CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of priority to Korean Patent Application No. 10-2019-0113103, filed in the Korean Intellectual Property Office on Sep. 11, 2019, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a cap and a water-heating device including the same, and more particularly, relates to a cap for allowing an indoor water-heating device to be used outdoors and a water-heating device including the cap.

BACKGROUND

A water-heating device, such as a water heater, a boiler, or the like, may be installed indoors or outdoors depending on an installation environment.

In the related art, an outdoor water-heating device is manufactured to be suitable only for outdoor use, and an indoor water-heating device is manufactured to be suitable only for indoor use. Therefore, in a case where the outdoor water-heating device is installed indoors, it may not be easy to supply air and release exhaust gas, and in a case where the indoor water-heating device is installed outdoors, foreign matter may be introduced through a connecting adaptor installed at the top, an air supply tube, or an exhaust tube, and therefore the indoor water-heating device is more likely to malfunction.

When water-heating devices are separately manufactured for indoor use and outdoor use, it may be inefficient in terms of production and inventory management. Accordingly, a method for installing one product both indoors and outdoors is required.

SUMMARY

The present disclosure has been made to solve the above-mentioned problems occurring in the prior art while advantages achieved by the prior art are maintained intact.

An aspect of the present disclosure provides a cap for allowing one product to be installed both indoors and outdoors by converting an indoor water-heating device such that the indoor water-heating device is installed and used outdoors, and a water-heating device including the cap.

Another aspect of the present disclosure provides a cap for facilitating inventory management by allowing a water-heating device to be converted for indoor or outdoor use depending on an installation environment or a country in which the water-heating device is installed.

The technical problems to be solved by the present disclosure are not limited to the aforementioned problems, and any other technical problems not mentioned herein will be clearly understood from the following description by those skilled in the art to which the present disclosure pertains.

According to an aspect of the present disclosure, a cap for covering a top side of a case of a water-heating device includes a cover having a receiving space that is open at the bottom, the cover including an exhaust hole formed therein for releasing exhaust gas in the case to the outside, and an exhaust duct that is received in the receiving space and coupled to the cover and that forms an exhaust channel that connects an exhaust tube included in the case and the exhaust hole and releases the exhaust gas, in which the exhaust duct is formed of a material different from a material of the cover, and the material of the exhaust duct has higher heat resistance than the material of the cover.

According to another aspect of the present disclosure, a water-heating device includes a case that has an interior space therein and that includes an air supply tube that introduces air into the interior space and an exhaust tube that releases exhaust gas generated in the interior space, and a cap that covers a top side of the case. The cap includes a cover having a receiving space that is open at the bottom, the cover including an exhaust hole formed therein for releasing the exhaust gas in the interior space to the outside, and an exhaust duct that is received in the receiving space and coupled to the cover and that forms an exhaust channel that connects an exhaust tube included in the case and the exhaust hole and releases the exhaust gas, in which the exhaust duct is formed of a material different from a material of the cover, and the material of the exhaust duct has higher heat resistance than the material of the cover.
