The gas water heater 100 is a common type of kitchen appliance. Depending on the installation environment, the apparatuses are roughly classified into indoor-installed balancing apparatuses, forced air cleaners, and outdoor-installed outdoor apparatuses. Most of the indoor installation places are bathrooms, kitchens or balconies. The main installation place is the kitchen, and the gas water heater 100 has a single function and only provides domestic hot water due to the limitation of the house type and the gas pipeline. In order to solve the problem of kitchen stuffiness in summer, kitchen refrigeration products are increasingly used in the kitchen. The traditional wall-mounted air conditioner or the special kitchen air conditioner needs to be provided with an outdoor unit and occupies precious kitchen space, the mobile air conditioner has low refrigeration power, and the exhaust is indoor or needs to be specially provided with a large-diameter exhaust pipe to be communicated with the outside, so that the use is inconvenient. Although the products such as kitchen cooling and heating device can save space, the refrigeration effect is poor.

In the correlation technique, above-mentioned domestic gas instantaneous water heater and kitchen refrigeration product all set up alone for the kitchen that originally the space is not abundant becomes more crowded, and the kitchen refrigeration product refrigeration effect that can save space is unsatisfactory, therefore present kitchen refrigeration product all can not compromise refrigeration effect and installation space. The application provides a gas heater 100 can improve above-mentioned problem, and the gas heater 100 that the application provided integrates hot water function and refrigeration function, and same gas heater 100 can refrigerate when boiling water, and two kinds of functions can be realized to same product, can save installation space.

The application is described below with reference to specific embodiments in conjunction with the following drawings:

the embodiment provides a gas water heater 100, and the gas water heater 100 that this embodiment provided integrates hot water function and refrigeration function, and same gas water heater 100 can refrigerate when heating up water, and two kinds of functions can be realized to same product, can save installation space.

In the embodiment of the present application, the gas water heater 100 includes: a housing 110, the housing 110 having an inner cavity 112 and an air inlet (not shown) and an air outlet (not shown) communicating with the inner cavity 112; the hot water module 130, the hot water module 130 is set up in the cavity 112, is used for providing the hot water; the heat exchange module 120 is disposed in the inner cavity 112, the heat exchange module 120 includes a compressor 121, an expansion valve 122, a condenser 123 and an evaporator 124, the compressor 121, the condenser 123, the expansion valve 122 and the evaporator 124 are sequentially connected to form a circulation loop for a heat exchange medium to flow, the evaporator 124 exchanges heat with air entering the inner cavity 112 from the air inlet through the heat exchange medium, and the air after heat exchange is blown out of the inner cavity 112 from the air outlet.

In this embodiment, the heat exchange module 120 and the hot water module 130 are installed in the inner cavity 112 at the same time, and work independently therebetween, when a user starts a refrigeration mode, a high-temperature and high-pressure heat exchange medium flowing out of the compressor 121 enters the condenser 123, forms a low-temperature and high-pressure heat exchange medium after heat exchange is performed by the condenser 123, and forms a low-temperature and low-pressure heat exchange medium after heat exchange is performed by the expansion valve 122 and enters the evaporator 124. The evaporator 124 exchanges heat with the air in the inner cavity 112, absorbs heat of the air in the inner cavity 112, reduces the temperature of the air, and blows the low-temperature air out of the inner cavity 112 from the air outlet, thereby playing a role in refrigeration. The high-temperature low-pressure heat exchange medium flowing out of the evaporator 124 flows back to the compressor 121, and is thus circulated.

Similarly, if a user starts the heating mode, the high-temperature and high-pressure heat exchange medium flowing out of the compressor 121 enters the evaporator 124, the evaporator 124 exchanges heat with the air in the inner cavity 112, heat is released to the air in the inner cavity 112, the temperature of the air is raised, and the high-temperature air is blown out of the inner cavity 112 from the air outlet, so that the heating function is achieved. The heat exchange medium with low temperature and high pressure flowing out of the evaporator 124 passes through the expansion valve 122 to form a heat exchange medium with low temperature and low pressure, and then passes through the condenser 123 to form a heat exchange medium with high temperature and low pressure, and flows back to the compressor 121, and the cycle is repeated.

In this embodiment, the hot water module 130 and the heat exchange module 120 are both disposed in the inner cavity 112, the hot water module 130 is used for providing hot water, and the heat exchange module 120 is mainly used for cooling or heating, and integrates two functions, so as to reduce the occupied space of installation and reduce the occupied operating space of the kitchen.

It is easily understood that the gas water heater 100 is mainly installed in a kitchen, which would otherwise generate a large amount of heat during cooking, and thus the heating module mainly uses a cooling mode.

In addition, in the embodiment of the present application, the hot water module 130 is the same as the hot water supply portion of the gas water heater 100 in the related art, the heat exchange module 120 adopts the air conditioning principle, and the hot water module 130 and the heat exchange module 120 are optimized and combined together, so that the hot water supply function is suitable for being realized, the cooling purpose of the kitchen environment can be realized, the installation is convenient, and the installation space is saved.

In some embodiments, the heat exchanging module 120 further includes a heat exchanging fan 125, the heat exchanging fan 125 is disposed at the air outlet, and when the heat exchanging module 120 is in operation, the heat exchanging fan 125 is activated to discharge the air in the inner cavity 112 after exchanging heat with the evaporator 124 to the outside of the inner cavity 112 through the air outlet. Under the condition that the gas heat exchanger is installed in a kitchen, the heat exchange module 120 operates in a cooling mode, and the heat exchange fan 125 discharges cold air in the inner cavity 112 from the air outlet, thereby cooling the kitchen environment.

In some embodiments, the inner cavity 112 has a hot water chamber 113 and a heat exchange chamber 114 which are independent from each other, the air inlet and the air outlet are both communicated with the heat exchange chamber 114, the hot water module 130 is installed in the hot water chamber 113, and the heat exchange module 120 is installed in the heat exchange chamber 114.

In some embodiments, the hot water chamber 113 and the heat exchange chamber 114 are independent from each other, so that the hot water module 130 and the heat exchange module 120 do not interfere with each other. That is, the heat exchange module 120 and the hot water module 130 are two separately integrated modules, and can work separately therebetween, so that they can be separately maintained when one of the modules fails, thereby reducing the maintenance cost of the gas water heater 100.

The hot water module 130 heats water introduced into the hot water chamber 113 by mainly burning gas, and a large amount of heat is generated during the combustion of the gas. Likewise, heat exchange module 120 also generates heat during operation. Under the condition that only the hot water module 130 works, the hot water module 130 generates a large amount of heat, which may cause the ambient temperature of the heat exchange module 120 not working to rise, and the heat exchange module 120 does not work and can not automatically dissipate heat, and the service life of the heat exchange module 120 is affected by the overhigh ambient temperature. Similarly, in the condition that only the heat exchange module 120 operates, the heat exchange module 120 mainly operates in the cooling mode, and the ambient temperature in the entire inner cavity 112 may be relatively low, which may also affect the service life of the hot water module 130.

Under the condition that the hot water module and the hot water module work simultaneously, the hot water module 130 is used for providing hot water and mainly heats water through gas combustion, the hot water cavity 113 can generate a large amount of heat, and the temperature in the hot water cavity 113 is high. And heat exchange module 120 mainly operates the refrigeration mode, and the temperature in heat exchange cavity 114 is lower relatively, and hot water cavity 113 and heat exchange cavity 114 set up independently each other, can avoid hot-blast and the cold wind in the heat exchange cavity 114 in the hot water cavity 113 to concatenate each other, influence heat exchange module 120's refrigeration effect.

In some embodiments, a partition 116 is disposed in the housing 110, and the partition 116 divides the inner cavity 112 into a hot water chamber 113 and a heat exchange chamber 114 that are independent of each other.

In some embodiments, the hot water chamber 113 and the heat exchange chamber 114 are separated by the partition 116, and the hot water chamber 113 and the heat exchange chamber 114 which are independent of each other can be implemented in the inner chamber 112, so that the hot water chamber 113 and the heat exchange chamber 114 are independently arranged in the same inner chamber 112, thereby reducing the volume of the whole gas water heater 100 as a whole and reducing the occupied space of the gas water heater 100.

In order to further reduce the heat exchange between the hot water chamber 113 and the refrigeration chamber, in some embodiments, the partition 116 has a heat insulation function, and specifically, the partition 116 may be made of a heat insulation material, or the partition 116 may be provided with a heat insulation layer made of a heat insulation material. In other embodiments, both the hot water module 130 and the heat exchange module 120 may be coated with insulation. By arranging the heat insulation material, the heat exchange between the hot water chamber 113 and the refrigeration chamber is further reduced, and the hot water temperature and the refrigeration temperature are ensured.

The partition 116 may be disposed horizontally, vertically, or obliquely, or the partition 116 may also be a profiled plate to match the external shape of the hot water module 130 and the heat exchange module 120. In some embodiments, the partition 116 is a straight plate and is disposed in a vertical direction, so that the hot water chamber 113 and the refrigeration chamber are disposed side by side in a horizontal direction, and by disposing the hot water chamber 113 and the refrigeration chamber to be distributed side by side in the horizontal direction, the overall height of the gas water heater 100 can be reduced, and the installation is facilitated.

Because in the refrigeration process of the heat exchange module 120, the condenser 123 generates heat, in order to reduce the influence of the heat exchange of the condenser 123 on the refrigeration, the partition plate 116 divides the heat exchange chamber 114 into a first sub-chamber 1142 and a second sub-chamber 1144, the condenser 123 is arranged in the first sub-chamber 1142, the compressor 121, the expansion valve 122 and the evaporator 124 are arranged in the second sub-chamber 1144, and the air inlet and the air outlet are all communicated with the second sub-chamber 1144.

In some embodiments, the hot water module 130 includes an exhaust channel 131, the heat exchange module 120 further includes a heat dissipation channel 126, the heat dissipation channel 126 communicates with the inner cavity 112, the condenser 123 is disposed adjacent to the heat dissipation channel 126, and the heat dissipation channel 126 communicates with the exhaust channel 131.

In some embodiments, the exhaust channel 131 has a connection port 132, and an end of the heat dissipation channel 126 remote from the condenser 123 is connected to the connection port 132.

In some embodiments, the heat dissipation channel 126 is connected to the exhaust channel 131 through the connection port 132 at one end and to the condenser 123 at the other end. In other words, the hot air in the heat dissipation channel 126 is collected into the exhaust channel 131 and exhausted through the exhaust channel 131. That is, for the hot water module 130, only the connection port 132 is disposed on the exhaust channel 131, and no other structure is added, so that the manufacturing cost of the whole gas water heater 100 is reduced.

In some embodiments, the housing 110 has a heat exchange port 117 in communication with the interior cavity 112, the heat sink channel 126 is in communication with the heat exchange port 117, and the condenser 123 is disposed proximate to the heat exchange port 117.

The heat exchange module 120 further includes a heat dissipation fan 128, the heat dissipation fan 128 is disposed on a side of the condenser 123 far away from the heat exchange port 117, and in a working process of the heat exchange module 120, the heat dissipation fan 128 blows air to the condenser 123, so as to take away heat on the condenser 123 and refrigerate a heat exchange medium passing through the condenser 123.

In addition, in other embodiments, the heat dissipation channel 126 may extend into the first sub-chamber 1142 through the heat exchange port 117, and the condenser 123 and the heat dissipation fan 128 may be disposed in the heat dissipation channel 126. Also, a heat radiation fan 128 is provided on a side of the condenser 123 remote from the heat exchange port 117.

In some embodiments, a check valve 127 is disposed on the heat dissipation channel 126, and the check valve 127 is used to prevent the hot air in the exhaust channel 131 from flowing into the heat dissipation channel 126.

The check valve 127 allows air flow from the heat dissipation channel to the exhaust channel 131 of the hot water module 130, but prevents air of the hot water module 130 from flowing backward to the heat dissipation channel. By installing the check valve 127 on the heat dissipation channel, the smoke in the hot water module 130 is prevented from entering the inner cavity 112 of the housing 110 of the gas water heater 100, and further the smoke in the gas water heater 100 is prevented from being blown into the kitchen.

In some embodiments, the heat dissipation channel 126 and the exhaust channel 131 are disposed above the internal cavity 112. The exhaust channel 131 and the heat dissipation channel 126 are disposed above the inner cavity 112, and can exhaust the waste gas and the hot gas by using the flowing direction of the gas itself, and the waste gas and the hot gas can be exhausted without providing other driving components.

By arranging the hot water module 130 and the heat exchange module 120 to be distributed side by side in the horizontal direction, the overall height of the gas water heater 100 can be reduced, and the exhaust channel 131 and the heat dissipation channel are ensured to be located at the same height, which facilitates the pipeline arrangement.

In some embodiments, the evaporator 124 is disposed between the air inlet and the air outlet, and is disposed proximate to the air outlet. That is, the evaporator 124 is disposed in the channel formed by the air inlet and the air outlet, so that the air entering the inner cavity 112 from the air inlet needs to be subjected to heat exchange by the evaporator 124 when being discharged from the air outlet, thereby improving the heat exchange effect.

In some embodiments, the hot water module 130 further includes a combustion chamber 133 and a combustion heat exchanger 134, the combustion chamber 133 is communicated with both the gas pipe and the exhaust channel 131, when hot water is required to be provided, the gas enters the combustion chamber 133 through the gas pipe for combustion, and hot flue gas generated by the combustion is exhausted to the outside through the exhaust channel 131.
