the electric food preparation appliance illustrated in fig1 and 2 comprises a rotary working tool , or blades , 1 installed in a jar 2 . if desired , rotary working tool 1 can be removably installed . more particularly , the appliance comprises a base 3 receiving a work container 4 forming jar 2 . a motor ( not shown ) is housed in base 3 . the motor is coupled with a drive mechanism 5 designed to cooperate with a drive element 6 disposed under blender jar 2 and connected to rotary working tool 1 . thus , as is clearly visible in fig2 , rotary working tool 1 is actuated through the bottom of jar 2 by means of drive element 6 . a lid 7 is associated with jar 2 . lid 7 presents an opening 8 advantageously placed at the bottom of a depression , or recess . opening 8 extends essentially above rotary working tool 1 installed in jar 2 . lid 7 has two diametrically opposed side recesses 9 adjacent to opening 8 . the appliance also comprises a mixing accessory 10 , shown in fig1 to 4 . mixing accessory 10 is adapted to be installed in opening 8 . as is clearly visible in fig2 , mixing accessory 10 extends then into jar 2 . mixing accessory 10 forms a spoon 11 . advantageously , spoon 11 can touch the walls of jar 2 when mixing accessory 10 is in place in opening 8 of lid 7 . mixing accessory 10 presents a hollow sleeve 12 forming an emerging conduit 13 . thus hollow sleeve 12 allows food ingredients to be introduced into jar 2 from the upper end of mixing accessory 10 installed in opening 8 of lid 7 . more particularly , hollow sleeve 12 forms a funnel 14 . the introduction of ingredients into mixing accessory 10 in place in opening 8 of lid 7 is thus facilitated . funnel 14 is provided at the end of conduit 13 opposed to spoon 11 . the other end of conduit 13 emerges near spoon 11 . mixing accessory 10 is provided with a flange 15 designed to be supported on lid 8 around opening 7 . flange 15 is arranged between spoon 11 and funnel 14 . if desired , hollow spoon 11 and handle 12 can be made of different materials . as is clearly visible in fig2 and 3 , mixing accessory 10 comprises a tubular part 16 forming funnel 14 , flange 15 and the major part of conduit 13 . tubular part 16 is advantageously made of a rigid material , such as for example polycarbonate . mixing accessory 10 also comprises a part 17 forming spoon 11 and part of conduit 13 from which spoon 11 projects . part 17 is made of a more flexible material , such as for example polypropylene . part 17 can advantageously be overmolded on tubular part 16 . thus , mixing accessory 10 at least partially present a hollow sleeve 12 made of a material more rigid than the material from which spoon 11 is made . the appliance also has a blocking element 20 , shown in fig1 to 4 . blocking element 20 is provided to be placed in opening 8 of lid 7 , as shown in fig1 and 4 . moreover , blocking element 20 is provided to be engaged in one end of hollow sleeve 12 . more specifically , blocking element 20 is constructed to be placed in the end of hollow sleeve 12 opposed to spoon 11 , as shown in fig2 and 3 . as shown in fig4 , blocking element 20 can be placed in opening 8 of lid 7 in place of mixing accessory 10 . blocking element 20 forms advantageously a container 21 . blocking element 20 can in particular be provided with level markings , or graduations , and can thus form a measuring cap . alternatively , the blocking element 20 can be provided at its bottom with at least one opening for the flow of liquid into jar 2 when blocking element 20 is in place in opening 8 or in mixing accessory 10 . the appliance further comprises a side support 30 designed to receive mixing accessory 10 . side support 30 presents an arm 31 surmounted by a protuberance 32 . protuberance 32 advantageously presents a storage body 33 and a support body 34 . hollow sleeve 12 is configured to be engaged on side support 30 . more particularly , side support 30 extends from base 3 . according to the preferred embodiment illustrated in fig1 , 2 and 4 , side support 30 is secured to , or integral with , a piece 35 forming a ring 36 . side support 30 and piece 35 are advantageously mounted to be removable from a case 40 forming a component of base 3 . for this purpose , ring 36 presents internal shaped regions , or conformations , e . g . protrusions , 37 adapted to cooperate with mating side shaped regions , or conformations , e . g . recesses , 41 formed on an upper part 42 of case 40 . side support 30 is advantageously adapted to occupy any one of several possible positions relative to case 40 . for the preferred embodiment shown in fig1 , there are four internal conformations 37 and eight side conformations 41 . thus , the user can choose from among eight available positions for side support 30 on case 40 . advantageously , the lower end of mixing accessory 10 , when in place on side support 30 , is disposed laterally at a distance from the lower part of the appliance , as shown in fig4 . mixing accessory 10 makes it possible to use spoon 11 to pour ingredients into jar 2 through opening 8 . mixing accessory 10 can also be constructed to provide funnel 14 through which ingredients can be poured into conduit 13 in jar 2 through opening 8 . mixing accessory 10 , when in place in jar 2 , can also be used to mix the ingredients present in jar 2 and / or to scrape food off of the internal wall of jar 2 , in particular during preparation of a puree , for example of chickpeas . blocking element 20 can be used to close the upper end of hollow sleeve 12 or to directly seal opening 8 of lid 7 . side support 30 can be used to receive mixing accessory 10 , as shown in fig4 , in which hollow sleeve 12 is engaged on side support 30 . storage body 33 is then engaged in the end of conduit 13 adjacent spoon 11 and the upper end of spoon 11 rests on support body 34 . if desired , side support 30 can also be used to hold blocking element 20 in an upside down orientation . the user can choose the orientation of side support 30 relative to case 40 by positioning internal conformations 37 of ring 36 opposite selected side conformations 41 of case 40 . thus , side support 30 can be placed on the left - hand side of the appliance , as shown in fig1 , 2 and 4 , but also on the right - hand side of the appliance , or opposite the front face or the rear face , or in any other intermediate position permitted by internal conformations 37 of ring 36 . side support 30 is thus not necessarily placed on the side of the appliance . the appliance according to the invention is thus particularly practical to use . fig5 shows an alternative embodiment differing from the embodiment shown in fig1 to 4 in that base 3 ′ includes case 40 , but does not carry side support 30 or piece 35 . instead , side support 30 is replaced by a side support 30 ′, which is designed to receive mixing accessory 10 and extends from , and may be integral with , blender jar 4 ′. blocking element 20 on lid 7 can also be used with mixing accessory 10 , in the same manner as blocking element 20 and mixing accessory 10 of the embodiment illustrated in fig1 to 4 . as a complementary alternative , side support 30 ′ is not necessarily disposed on the rear face of the appliance as illustrated on fig5 . fig6 illustrates an alternative embodiment differing from the embodiment illustrated in fig1 to 4 in that side support 30 ″ extends from , and may be integral with , lid 7 ″, instead of from blender jar 4 , or 4 ′, or from base 3 . in the embodiment of fig6 , base 3 ′ includes case 40 , but does not carry side support 30 or piece 35 . blocking element 20 on lid 7 ″ can also be used with mixing accessory 10 , in the same manner as blocking element 20 and mixing accessory 10 of the embodiment illustrated in fig1 to 4 . as a complementary alternative , side support 30 ″ is not necessarily positioned at the rear face of the appliance as illustrated on fig6 . as a complementary alternative , spoon 11 could be made of a flexible material , such as for example silicone . as a complementary alternative , mixing accessory 10 can in particular be made entirely of one material . as a complementary alternative , mixing accessory 10 need not be provided with flange 15 . as a complementary alternative , the motor could be integrated into blender jar 4 , 4 ′ and base 3 , 3 ′ can be eliminated . as a complementary alternative , protuberance 33 does not necessarily extend in a vertical direction , but could in particular be tilted , for example toward the front face of the appliance . the present invention is by no means limited to the embodiment described and its alternatives , but includes many modifications within the framework of the claims .
