Description

Technical Field

[0001] This application belongs to the technical field of electrical appliances, and particularly relates to a water heater. Background Art

[0002] A heat pump water heater is an energy-efficient hot water supply device. The heat pump water heater includes an evaporator, a compressor, a condenser, and a water tank. After the compressor pressurizes the low-temperature and low-pressure gaseous refrigerant to form a high-temperature and high-pressure gas, it outputs it into the condenser. The condenser contacts the water tank to heat the water in the water tank. The refrigerant with a reduced temperature after heat exchange enters the evaporator, and the evaporator promotes the gasification of the refrigerant to form a low-temperature and low-pressure gaseous refrigerant again and enter the compressor, and the heating is completed through continuous circulation.

[0003] In the prior art, the inside of the heat pump water heater is divided into a first area and a second area. The water tank and the condenser are installed in the first area, and the compressor and the evaporator are installed in the second area. The compressor is located at the bottom of the second area, and the evaporator is located at the top of the second area.

[0004] However, the above distribution method squeezes the compressor and the evaporator in the same space, resulting in poor air circulation in the second area, which is not conducive to heat exchange between the evaporator and the compressor and affects the working efficiency of the heat pump water heater. Summary of the Invention

[0005] This application provides a water heater, which is beneficial to optimizing the air circulation inside the water heater, improving the heat exchange efficiency, and further improving the working efficiency of the water heater.

[0007] In a possible implementation manner, it further includes: a first partition plate for partitioning the first chamber and the second chamber; and / or, a second partition plate for partitioning the second chamber and the third chamber.

[0008] In a possible implementation manner, it further includes: a first partition plate, a second partition plate, and a connecting frame for connecting the first partition plate and the second partition plate.

[0009] In a possible implementation manner, it further includes: an electric control device, which is disposed in the second chamber and fixedly connected to the connecting frame; and / or, a throttling device, which is disposed in the second chamber and in the circulation loop, and the throttling device is fixedly connected to the connecting frame; and / or, the compressor is fixedly connected to the connecting frame.

[0010] In a possible implementation manner, the housing includes a first housing corresponding to the first chamber, a second housing corresponding to the second chamber, and a third housing corresponding to the third chamber. Two ends of the second housing are detachably connected to the first housing and the third housing respectively.

[0011] In a possible implementation manner, an overflow hole for communicating the second chamber and the third chamber is provided on the second partition plate.

[0012] In a possible implementation manner, an air inlet is provided on the second housing, an air outlet is provided on the first housing, and a fan assembly is disposed in the third chamber. The fan assembly is used to drive the air flow to discharge from the air inlet through the second chamber, the overflow hole and the third chamber in sequence and then from the air outlet.

[0013] In a possible implementation manner, the third chamber includes a first end facing the second chamber along the axial direction of the housing and a second end away from the second chamber. The evaporator is disposed at the first end, the air outlet is opened at the second end, and the fan assembly is arranged adjacent to the air outlet.

[0014] In a possible implementation manner, the fan assembly includes: a housing, which defines an overflow channel with both ends open. One end of the housing extends to the periphery of the evaporator, and the other end extends to the air outlet; a fan, which is disposed inside the housing.

[0015] In a possible implementation manner, the diameter of the air outlet is smaller than the diameter of the third chamber. Along the axial direction of the housing and from the second chamber towards the air outlet, the cross-sectional area of at least part of the overflow channel gradually decreases.

[0016] The water heater provided by this application divides the inner cavity defined by the outer shell into a first chamber, a second chamber, and a third chamber. The water tank assembly, the compressor, and the evaporator are respectively placed in the first chamber, the second chamber, and the third chamber. When the water heater is working, the compressor compresses the gaseous refrigerant to form a high-pressure and high-temperature gas, and transports the high-temperature and high-pressure gas to the condenser of the water tank assembly, thereby heating the water in the water tank body. After heat exchange, the temperature of the refrigerant decreases and part of it condenses into a liquid state. The low-temperature refrigerant enters the evaporator, and the evaporator promotes the evaporation of the refrigerant into a gas and transports it back to the compressor again. Therefore, when the compressor and the evaporator are respectively placed in two chambers, more sufficient space will be left around the compressor and the evaporator, thereby improving the air circulation in the inner cavity, being beneficial to the heat dissipation of the compressor. By installing a fan assembly, the speed of the air flow in the inner cavity is further accelerated, and the heat dissipation efficiency of the compressor is improved, thereby ensuring that the compressor can operate continuously and stably. At the same time, it can also ensure that there is sufficient low-temperature air supply for the evaporator, improve the heat exchange efficiency of the evaporator, enable the evaporator to quickly evaporate the liquid refrigerant into a gas state, be beneficial to improving the circulation efficiency of the refrigerant in the water heater, and further improve the working efficiency of the water heater.

These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below in conjunction with the drawings in the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0032] In the description of the present invention and the claims and the above - mentioned drawings, the terms "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein, for example.

[0033] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0034] As shown in the background art, in the prior art, a heat pump water heater is divided into a first region and a second region. A water tank and a condenser are installed in the first region, and a compressor and an evaporator are installed in the second region. The compressor is located at the bottom of the second region, and the evaporator is located at the top of the second region. However, in this way, the compressor and the evaporator are squeezed into the same space, resulting in poor air circulation in the second region, which is not conducive to heat exchange between the evaporator and the compressor and affects the working efficiency of the heat pump water heater.

[0035] To address the above technical problems, an embodiment of the present application provides a water heater, which includes a housing, a water tank assembly, a compressor, an evaporator, and a fan assembly. The housing defines an inner cavity, which is divided into a first chamber, a second chamber, and a third chamber. The water tank assembly, the compressor, and the evaporator are respectively disposed in the first chamber, the second chamber, and the third chamber. The water tank assembly includes a water tank body and a condenser. The evaporator, the condenser, and the compressor form a circulation loop. The fan is disposed in the second chamber or the third chamber to dissipate heat for the compressor. Thus, when the water heater operates, the compressor compresses the gaseous refrigerant to form a high-pressure and high-temperature gas, and transports the high-temperature and high-pressure gas to the condenser of the water tank assembly to heat the water in the water tank body. After heat exchange, the temperature of the refrigerant decreases and part of it condenses into a liquid state. The low-temperature refrigerant enters the evaporator, and the evaporator promotes the evaporation of the refrigerant into a gas and transports it back to the compressor again. Therefore, when the compressor and the evaporator are respectively placed in two chambers, more sufficient space will be left around the compressor and the evaporator, which can improve the air circulation in the inner cavity, facilitate the heat dissipation of the compressor, and further accelerate the air flow speed in the inner cavity by installing the fan assembly, improving the heat dissipation efficiency of the compressor, thus ensuring the continuous and stable operation of the compressor. At the same time, it can also ensure an adequate supply of low-temperature air for the evaporator, improve the heat exchange efficiency of the evaporator, enable the evaporator to quickly evaporate the liquid refrigerant into a gas state, facilitate the improvement of the refrigerant circulation efficiency in the water heater, and further improve the working efficiency of the water heater.

[0036] The following uses specific embodiments to elaborate in detail on the technical solution of the present application and how the technical solution of the present application solves the above technical problems. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe the embodiments of the present application with reference to the accompanying drawings:

[0037] See Figure 1 As shown in the figure, the water heater 100 provided by the embodiment of the present application includes a housing 110, a water tank assembly 120, a compressor 180, and an evaporator 130. Among them, the inner cavity of the housing 110 includes a first chamber 1111, a second chamber 1121, and a third chamber 1131 that are sequentially distributed along its own axis and are separated from each other; the water tank assembly 120 is disposed in the first chamber 1111, and the water tank assembly 120 includes a water tank body 121 and a condenser 122 disposed in the water tank body 121; the compressor 180 is disposed in the second chamber 1121; the evaporator 130 is disposed in the third chamber 1131, and the evaporator 130, the condenser 122, and the compressor 180 form a circulation loop; the fan assembly 140 is used to dissipate heat for the compressor 180.

[0038] In the embodiment of the present application, the compressor 180 compresses the gaseous refrigerant to form a high-pressure and high-temperature gas, and transports the high-temperature and high-pressure gas to the condenser 122 of the water tank assembly 120, thereby heating the water in the water tank body 121. After heat exchange, the temperature of the refrigerant decreases and part of it condenses into a liquid state. The low-temperature refrigerant enters the evaporator 130, and the evaporator 130 promotes the evaporation of the refrigerant into a gas and transports it back to the compressor 180 again, thus realizing a single cycle. The refrigerant can circulate multiple times in the circulation loop to achieve the supply of hot water. During the process of compressing the gaseous refrigerant, the compressor 180 releases a large amount of heat. Overheating of the compressor 180 will affect its working efficiency and easily accelerate the aging of the internal parts of the compressor 180, affecting the service life of the compressor 180. Therefore, it is necessary to improve the heat dissipation efficiency of the compressor 180. At the same time, the evaporator 130 also needs to maintain good heat exchange efficiency to quickly evaporate the liquid refrigerant into a gaseous refrigerant.

[0039] In the prior art, the compressor 180 and the evaporator 130 are placed in the same space, and the compressor 180 and the evaporator 130 mutually occupy the heat exchange space, resulting in poor air circulation in the inner cavity, and the heat exchange efficiency of the compressor 180 and the evaporator 130 is relatively low. In the embodiment of the present application, the compressor 180 and the evaporator 130 are respectively arranged in the second chamber 1121 and the third chamber 1131. Sufficient heat exchange space can be left around the compressor 180 and the evaporator 130, which is beneficial to improving the air circulation in the inner cavity. Among them, the second chamber 1121 and the third chamber 1131 can be communicated. Setting the fan assembly 140 in the second chamber 1121 or the third chamber 1131 can promote the air flow in the second chamber 1121 and the third chamber 1131, thereby improving the heat exchange efficiency of the compressor 180 and the evaporator 130, ensuring the continuous and stable operation of the compressor 180, improving the evaporation efficiency of the evaporator 130, being beneficial to increasing the circulation speed of the refrigerant in the water heater 100, and thus improving the working efficiency of the water heater 100. Of course, the specific installation position of the fan assembly 140 is not limited in the embodiment of the present application, and can be reasonably selected according to the sizes and positions of the compressor 180 and the evaporator 130, as long as it can promote the air circulation in the inner cavity.

[0040] Furthermore, since the evaporator 130 and the compressor 180 are arranged in two chambers, the evaporator 130 has a larger installation space. Therefore, the volume of the evaporator 130 can be appropriately increased to increase the surface area of the evaporator 130 in contact with the air, which is beneficial to further improving the evaporation efficiency of the evaporator 130, thereby accelerating the circulation speed and improving the working efficiency of the water heater 100. In addition, increasing the blank space in the inner cavity can also reduce the air flow resistance of the air flowing in the inner cavity, which is beneficial to reducing the noise generated by the air flow formed by the start of the fan assembly 140 in the inner cavity and improving the use experience of the water heater 100.

[0041] In some implementable ways, refer to Figure 1 and Figure 2 As shown, the embodiments of the present application further include: a first partition plate 151 and a second partition plate 152. The first partition plate 151 is used to partition the first chamber 1111 and the second chamber 1121, and the second partition plate 152 is used to partition the second chamber 1121 and the third chamber 1131.

[0042] In specific implementation, the first partition plate 151 and the second partition plate 152 are connected to the inner wall of the housing 110, which can play a role in supporting the housing 110 and is beneficial to improving the structural strength of the water heater 100. Among them, the first partition plate 151 can be set to partition the first chamber 1111 from the second chamber 1121 to prevent low-temperature air from entering the first chamber 1111 and affecting the operation of the water tank assembly 120. The second partition plate 152 can be set to only partition the second chamber 1121 and the third chamber 1131 in terms of positional relationship, but the second chamber 1121 and the third chamber 1131 remain connected. In this way, the fan assembly 140 can simultaneously promote the air circulation in the second chamber 1121 and the third chamber 1131, improve the heat exchange efficiency of the compressor 180 and the evaporator 130, and ensure the efficient and stable operation of the water heater 100.

[0043] In some implementable ways, refer to Figure 1 and Figure 2 As shown, the embodiments of the present application further include: a first partition plate 151, a second partition plate 152 and a connecting frame 153. The connecting frame 153 is used to connect the first partition plate 151 and the second partition plate 152.

[0044] In some embodiments, the connecting frame 153 connects the first partition plate 151 and the second partition plate 152 into a whole to form a fixing bracket 150. The compressor 180, the evaporator 130 and other electrical components in the water heater 100 can be fixed on the fixing bracket 150. In this way, when it is necessary to repair the water heater 100, only the housing 110 needs to be removed to expose the complete internal structure of the water heater 100, so that the corresponding part can be directly repaired. Compared with the prior art in which the compressor 180, the evaporator 130, etc. are fixed on the inner wall of the housing 110 and the housing 110 and the electrical components fixed on the housing 110 need to be removed together during maintenance, the removal work in the embodiments of the present application is simpler and more convenient to operate, which is beneficial to improving the repair efficiency of the water heater 100 and saving the maintenance cost of the water heater 100.

[0045] In some implementable ways, refer to Figure 1As shown in the figure, the embodiment of the present application further includes: an electric control device 160 and a throttling device 170. The electric control device 160 and the throttling device 170 can both be arranged in the second chamber 1121. The throttling device 170 is arranged in the circulation loop, and the electric control device 160, the throttling device 170 and the compressor 180 are all fixedly connected to the connecting frame 153.

[0046] It should be noted that the electric control device 160 is used for electrically connecting with devices such as the compressor 180 and the evaporator 130, so as to control the start or stop of the water heater 100 according to the user's instruction. The throttling device 170 is arranged in the circulation loop and plays a role in throttling and reducing pressure and regulating the flow rate. Since the temperature and pressure of the high-temperature and high-pressure gaseous refrigerant are both in a relatively high state after being condensed into a liquid by the condenser 122, and the pressure in the evaporator 130 is relatively small, if the refrigerant flowing out of the condenser 122 is directly transported to the evaporator 130, it is easy to cause damage to the evaporator 130. Therefore, a throttling device 170 can be arranged in the circulation loop to reduce the pressure of the refrigerant by means of narrowing the refrigerant passage and then transport it to the evaporator 130, which is beneficial to ensuring that the evaporator 130 can operate efficiently and stably continuously. At the same time, the throttling device 170 can also adjust the heating capacity of the water heater 100 by controlling the flow rate of the refrigerant in the circulation loop.

[0047] It can be understood that in order to improve the evaporation efficiency of the evaporator 130, the volume of the evaporator 130 can be appropriately increased, so as to increase the surface area of the evaporator 130 in contact with the air. Therefore, the installation space left for other structures in the third chamber 1131 is relatively small, while the space occupied by the compressor 180 in the second chamber 1121 is relatively small, and a relatively large installation space can be left. Moreover, the connecting bracket is located in the second chamber 1121, and the structural strength here is higher. Therefore, the compressor 180, the electric control device 160 and the throttling device 170 can all be fixed on the connecting bracket to improve the space utilization rate of the second chamber 1121. Among them, the specific layout manner of the compressor 180, the electric control device 160 and the throttling device 170 in the second chamber 1121 is not limited in the embodiment of the present application, as long as a certain distance is maintained between the three to ensure the air circulation in the second chamber 1121.

[0048] In some feasible ways, as shown in Figure 1 the figure, the housing 110 of the embodiment of the present application includes a first housing 111 corresponding to the first chamber 1111, a second housing 112 corresponding to the second chamber 1121, and a third housing 113 corresponding to the third chamber 1131. The two ends of the second housing 112 are detachably connected to the first housing 111 and the third housing 113 respectively.

[0049] In specific implementation, the first partition plate 151 can be fixedly connected to the first housing 111, and the second partition plate 152 can be detachably connected to the third housing 113 or the second housing 112. When it is necessary to repair the devices in the second chamber 1121 or the third chamber 1131, the second housing 112 or the third housing 113 can be detached separately, which will not affect the layout of the wire harness or pipeline in the water heater 100, and the repair cost is relatively low, which is beneficial to improving the repair efficiency of the water heater 100. Among them, the second housing 112 and the third housing 113 can be set as a sleeve structure sleeved on the fixed bracket 150, or the second housing 112 can be set as two detachable symmetrical structures, so that the second housing 112 can be detached separately without detaching the first housing 111 and the second housing 112, and the operation is more convenient. Of course, the specific structures of the second housing 112 and the third housing 113 are not limited in the embodiments of the present application and can be reasonably selected according to the shape structure of the water heater 100.

[0050] In some implementable ways, referring to Figure 1 and Figure 2 As shown, an overflow hole (not shown in the figure) for communicating the second chamber 1121 and the third chamber 1131 is provided on the second partition plate 152 of the embodiment of the present application.

[0051] It can be understood that providing an overflow hole on the second partition plate can balance the pressures in the second chamber 1121 and the third chamber 1131, avoid excessive pressure difference between the second chamber 1121 and the third chamber 1131 and cause damage, and is beneficial to ensuring the safe operation of the water heater 100. Further, the fan assembly 140 is arranged in the second chamber 1121 or the third chamber 1131. In this way, when the fan assembly 140 is started, it can promote the air circulation in the second chamber 1121 and the third chamber 1131 at the same time, which is beneficial to the fan assembly 140 to exert greater benefits, improve the heat exchange efficiency of the evaporator 130, the compressor 180, the electronic control device 160, etc., and then improve the working efficiency of the water heater 100 and ensure the continuous and stable operation of the water heater 100.

[0052] In some implementable ways, referring to Figure 1 As shown, an air inlet 1122 is provided on the second housing 112 of the embodiment of the present application, and an air outlet 1132 is provided on the first housing 111. The fan assembly 140 is arranged in the third chamber 1131, and the fan assembly 140 is used to drive the air flow to discharge from the air outlet 1132 after passing through the second chamber 1121, the overflow hole and the third chamber 1131 in sequence from the air inlet 1122.

[0053] In some embodiments, the fan assembly 140 drives the air flow to enter the second chamber 1121 from the air inlet 1122, flows through the electronic control device 160, the compressor 180 and the throttling device 170, then enters the third chamber 1131 through the current-carrying hole, flows through the evaporator 130, and finally discharges from the air outlet 1132. In this way, after the fan assembly 140 is started, the heat of the electronic control device 160, the compressor 180, the throttling device 170 and the evaporator 130 can be taken out from the air outlet 1132, which is beneficial to improving the heat exchange efficiency of the devices in the second chamber 1121 and the third chamber 1131, and ensuring the safe and efficient operation of the water heater 100. Further, heat dissipation fins can be provided on the electronic control device 160 to increase the heat exchange area, thereby improving the heat dissipation efficiency of the electronic control device 160.

[0054] Wherein, both the air outlet 1132 and the air inlet 1122 can be set as grid structures. Among them, the air inlet grid can be formed as an annular grid arranged along the circumferential side of the second housing 112, or the air inlet grid can be provided at the part of the second housing 112 close to the compressor 180 and the electronic control device 160. The embodiments of the present application do not limit this. The air outlet grid can be provided on the side of the evaporator 130 facing away from the second chamber 1121 to ensure that the formed air flow can flow through each device. The grid structure can also cut the concentrated air flow formed by the fan assembly 140 into multiple sub-flows, improve the uniformity of the air flow, and at the same time reduce the noise generated by the high-frequency air flow, which is beneficial to improving the use experience of the water heater 100. Of course, the specific structures and positions of the air outlet 1132 and the air inlet 1122 are not limited in the embodiments of the present application and can be reasonably selected according to actual needs.

[0055] In some realizable ways, referring to Figure 1 As shown, the third chamber 1131 of the embodiment of the present application includes a first end facing the second chamber 1121 along the axial direction of the outer shell 110 and a second end away from the second chamber 1121. The evaporator 130 is arranged at the first end, the air outlet 1132 is opened at the second end, and the fan assembly 140 is arranged adjacent to the air outlet 1132.

[0056] In specific implementation, arranging the fan assembly 140 adjacent to the air outlet 1132 is beneficial to forcing the air flow to flow axially from the air inlet 1122 to the air outlet 1132, making the air flow smoother and realizing heat exchange more efficiently. At the same time, the evaporator 130 is arranged at one end away from the air outlet 1132, which can also prevent dust from entering the evaporator 130 and keep the evaporator 130 clean.

[0057] Further, the evaporator 130 is heavier than the fan assembly 140. Setting the evaporator 130 at the first end, i.e., the position close to the middle of the water heater 100, is conducive to keeping the overall center of gravity of the water heater 100 stable. At the same time, the fan assembly 140 is far from vibration sources such as the compressor 180 and the evaporator 130, which is conducive to reducing the natural frequency and avoiding resonance, thereby reducing the noise generated when the fan assembly 140 starts.

[0058] In some realizable ways, as shown in Figure 1 the fan assembly 140 of the embodiment of the present application includes: a housing 141 and a fan 142. The housing 141 defines a flow-through channel with both ends open. One end of the housing 141 extends to the periphery of the evaporator 130, and the other end extends to the air outlet 1132; the fan 142 is arranged inside the housing 141.

[0059] In specific implementation, the housing 141 plays a certain guiding role. The housing 141 extends from the air outlet 1132 to the evaporator 130, and a semi-closed air chamber can be formed on the periphery of the evaporator 130, so that all the air flow passes through the evaporator 130 and then is discharged from the air outlet 1132 along the flow-through channel, optimizing the flow path of the air flow, which is conducive to improving the heat exchange efficiency of the evaporator 130.

[0060] In addition, a detachable filter screen can be provided on the housing 141 to intercept dust in the air and prevent the dust from contacting the fan blades of the fan 142, causing wear, which is conducive to extending the service life of the fan assembly 140.

[0061] In a possible realizable way, the diameter of the air outlet 1132 is smaller than the diameter of the third chamber 1131. Along the axial direction of the housing 110 and from the second chamber 1121 towards the air outlet 1132, the cross-sectional area of at least part of the flow-through channel gradually decreases.

[0062] In some embodiments, the flow-through channel continuously contracts along the axial direction of the housing 110, so that the air flow flowing in the flow-through channel is continuously cooled, ensuring the heat exchange efficiency of the air flow. At the same time, the contraction of the flow-through channel can prevent the air flow from directly contacting the third housing 113, thereby preventing heat exchange between the air flow and the third housing 113 and causing cold loss, which is conducive to further improving the overall heat exchange efficiency of the water heater 100 and improving the working efficiency of the water heater 100.

[0063] In addition, setting the diameter of the air outlet 1132 to be smaller than the diameter of the third chamber 1131 is conducive to reducing the static pressure at the air outlet 1132, thereby reducing the load of the fan 142 at the air outlet 1132, helping to reduce the power of the fan 142, and further reducing the energy consumption of the water heater 100.

[0064] In summary, the water heater 100 provided by the embodiments of the present application includes a housing 110, a water tank assembly 120, a compressor 180, an evaporator 130, and a fan assembly 140. The inner cavity defined by the housing 110 is partitioned into a first chamber 1111, a second chamber 1121, and a third chamber 1131. The water tank assembly 120, the compressor 180, and the evaporator 130 are respectively disposed in the first chamber 1111, the second chamber 1121, and the third chamber 1131. The housing 110 is provided with an air inlet 1122 communicating with the second chamber 1121 and an air outlet 1132 communicating with the third chamber 1131. The fan assembly 140 is disposed in the third chamber 1131 near the air outlet 1132, and the second chamber 1121 communicates with the third chamber 1131. Thus, the compressor 180 and the evaporator 130 are respectively disposed in two chambers, leaving more space in the inner cavity, improving the air circulation in the inner cavity. The fan assembly 140 drives the air flow to enter from the air inlet 1122, sequentially pass through the second chamber 1121 and the third chamber 1131, and then flow out from the air outlet 1132. In this way, the air flow generated by the fan assembly 140 can jointly take out the heat generated by the compressor 180 and the evaporator 130, and provide sufficient low-temperature air for the evaporator 130. With sufficient space and small air flow resistance, it is beneficial to improve the heat exchange efficiency of the compressor 180 and the evaporator 130, and at the same time reduce the noise generated by the air flow in the inner cavity, thereby improving the use experience of the water heater 100.
