CROSS-REFERENCE TO RELATED APPLICATIONS

The application is the national stage entry of PCT/CN2018/115670, filed on Nov. 15, 2018, which is based upon and claims priority to Chinese Patent Application No. 201810997068.X, filed Aug. 29, 2018, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the field of air conditioner technologies, and more particularly, to an indoor unit of an air conditioner and an air conditioner.

BACKGROUND

At present, air conditioners are more and more indispensable household appliances in people's daily life. Conventional air conditioners are mainly used to realize cooling and heating functions of an indoor unit, and thus the functions are relatively single. With increasing requirements of users for the air conditioners, air conditioners with storage function have become a trend. The indoor unit of the existing storage type air conditioner is provided with a storage basket, and items in the storage basket are cooled or heated by cold air or hot air generated after performing heat exchange with a heat exchanger. Although the purpose of heating or cooling can be achieved, the use of the cold air or the hot air will be affected by an environment temperature, thereby resulting in poor cooling or heating effect.

SUMMARY

Embodiments of the present disclosure provide an indoor unit of an air conditioner and an air conditioner, so as to solve the problem that the indoor unit of the air conditioner has poor effect when cooling or heating are performed by the cold air or the hot air during storage. In order to have a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not a general comment, nor is it intended to identify key/important constituent elements or describe the scope of protection of these embodiments. The sole purpose thereof is to present some concepts in a simplified form as a preface to the following detailed description.

According to a first aspect of the embodiments of the present disclosure, there is provided an indoor unit of an air conditioner, including an indoor unit housing, a heat exchanger, a conduit and one or more storage parts provided outside the indoor unit housing and/or inside the indoor unit housing, wherein one end of the conduit is connected to a liquid separator of the heat exchanger, the other end of the conduit is connected to a gas collecting pipe of the heat exchanger, and the conduit is used for heat exchange with the one or more storage parts.

Optionally, the storage part is a storage drawer, the indoor unit housing is provided with one or more installation openings, and the conduit is provided in a spiral shape at a position where the storage drawer is placed in the indoor unit housing,

when the storage drawer is in a closed state, the storage drawer passes through the installation opening and is located in the indoor unit housing, and the conduit is wound and sleeved on an outer wall of the storage drawer.

Optionally, the conduit is uniformly wound and sleeved on the outer wall of the storage drawer, and there is a set distance between the conduit and the outer wall of the storage drawer.

Optionally, elastic buckles are provided on both end faces of the storage drawer, corresponding positions in the indoor unit housing are provided with grooves, and the elastic buckles are matched with the grooves.

Optionally, the indoor unit housing is provided with sliding rails at both sides of the installation opening, and the storage drawer is slidably connected to the sliding rails.

Optionally, the indoor unit of the air conditioner further includes a controller and a temperature sensor, wherein the temperature sensor is provided in the storage part, an electronic expansion valve is provided on the conduit, an input end of the controller is electrically connected to the temperature sensor for receiving temperature signals sent by the temperature sensor, and an output end of the controller is electrically connected to the electronic expansion valve for controlling an opening of the electronic expansion valve.

Optionally, the conduit includes a first pipe section and a second pipe section, the first pipe section exchanges heat with the storage part, and a layer of thermal insulation material is provided on an outer wall of the second pipe section.

Optionally, the storage part is provided in a space between the heat exchanger and an air outlet in the indoor unit housing.

Optionally, the indoor unit of the air conditioner is a vase-shaped indoor unit of the air conditioner, the vase-shaped indoor unit includes a base, a main housing and a head and neck portion, the base, the main housing and the head and neck portion are sequentially connected from bottom to top to form a vase structure, the heat exchanger is provided in the main housing, the air outlet is provided on the main housing, and the storage part is provided in the main housing.

According to a second aspect of the embodiments of the present disclosure, there is provided an air conditioner, including the above-mentioned the indoor unit of the air conditioner.

Some technical solutions provided by the embodiments of the present disclosure may achieve following technical effects.

It is beneficial to a circulation of the refrigerant by connecting the conduit to the gas collecting pipe and the liquid separator of the heat exchanger respectively to form a loop with the heat exchanger. When the air conditioner is in a cooling working condition, the temperature of the refrigerant flowing through the heat exchanger (an evaporator) drops sharply due to the increase in space, and the decrease in pressure, at this time, the heat exchange is performed with the storage part through the conduit to cool the storage part; and when the air conditioner is in a heating working condition, the refrigerant flowing through the heat exchanger (a condenser) is a high-temperature and high-pressure liquid, at this time, the heat exchange is performed with the storage part through the conduit to heat the storage part, and is not easily affected by the environment temperature, thereby improving the cooling or heating effect.

It should be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not intended to limit the present disclosure.
