Description

Technical Field

[0001] The present application relates to the technical field of household appliances, for example, to an air conditioner with a water dispenser. Background Art

[0002] Existing water dispensers and air conditioners are two common electrical appliances that are usually installed independently. These two completely independent devices result in high investment costs and low energy efficiency.

[0003] To reduce operating costs and improve energy efficiency, an air conditioner with a water dispenser has been proposed. The air conditioner consists of an outdoor unit and an indoor cabinet. The outdoor unit houses a compressor and a four-way valve, while the indoor cabinet primarily contains an evaporator. The indoor cabinet also houses a water dispenser connected to a water source. The water dispenser primarily includes a first heat exchange chamber, a first heat exchanger, a first heat exchange tube, a second heat exchange chamber, a second heat exchanger, and a second heat exchange tube. When the air conditioner is cooling, the refrigerant flows from the compressor through the four-way valve into the first heat exchanger for heat exchange. The heat is absorbed by the energy storage fluid in the first heat exchange chamber and transferred to the first heat exchange tube, heating the water in the first heat exchange tube. The refrigerant then flows to the condenser for heat exchange, then passes through the throttle valve and enters the first three-way valve. From the normally open end, it enters the evaporator for cooling. From the normally open end, it enters the second three-way valve and flows into the second heat exchanger for heat exchange. The cold energy is absorbed by the energy storage fluid in the second heat exchange chamber and transferred to the second heat exchange tube, cooling the water in the second heat exchange tube. The refrigerant then flows from the second heat exchanger through the four-way valve back to the compressor, and the cycle repeats. When the air conditioner is heating, the refrigerant flows in the reverse direction.

[0004] During the implementation of the above-described embodiment, it was discovered that the related art has at least the following problems: When the air conditioner switches between cooling and heating modes, the cooling and heating modes of the first and second heat exchange tubes also change accordingly. The first and second heat exchange tubes are used to cool or heat the water within their respective tubes to provide cold and / or hot water. This switching between cooling and heating modes can increase energy consumption and lead to unnecessary energy waste.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0045] In some embodiments, combined Figure 1 and Figure 2As shown, an air conditioner 1 with a water dispenser is provided, comprising an air conditioner body 10, a water dispenser body 20, and a conversion element 30. The air conditioner body 10 includes a refrigerant circuit equipped with an electronic expansion valve 100. The water dispenser body 20 includes a hot water tank 200, a cold water tank 202, a first heat exchange circuit 204, and a second heat exchange circuit 210. The first heat exchange circuit 204 communicates with the refrigerant circuit on one side of the electronic expansion valve 100 and is configured to perform heat exchange with one of the hot water tank 200 and the cold water tank 202. The second heat exchange circuit 210 communicates with the refrigerant circuit on the other side of the electronic expansion valve 100 and is configured to perform heat exchange with the other of the hot water tank 200 and the cold water tank 202. The conversion element 30 is disposed between the first heat exchange circuit 204 and the second heat exchange circuit 210 and is configured to switch the water tank for heat exchange with the first heat exchange circuit 204 or the second heat exchange circuit 210 in response to switching the air conditioner body 10 between cooling mode and heating mode.

[0046] The electronic expansion valve 100 is used to expand high-temperature, high-pressure refrigerant into low-temperature, low-pressure refrigerant. The air conditioner 1 with a water dispenser provided in the disclosed embodiment has refrigerant circuits on both sides of the electronic expansion valve 100 connected to a first heat exchange circuit 204 and a second heat exchange circuit 210, respectively. This allows the refrigerant to flow into the first heat exchange circuit 204 and the second heat exchange circuit 210 before entering the electronic expansion valve 100 and after exiting the electronic expansion valve 100, exchanging heat with the water in the hot water tank 200 and the cold water tank 202. This utilizes the waste heat and cooling generated during the operation of the air conditioner to provide heat and cooling sources for the water dispenser body 20, reducing the water dispenser's power demand and overall system energy consumption.

[0047] The air conditioner 1 with a water dispenser provided in the embodiment of the present disclosure is provided with a conversion element 30 on the first heat exchange circuit 204 and the second heat exchange circuit 210 to switch the water tank for heat exchange with the first heat exchange circuit 204 and the second heat exchange circuit 210 in response to the switching of the air conditioner body 10 between the cooling mode and the heating mode, so that the hot water tank 200 constantly provides hot water and the cold water tank 202 constantly provides cold water, so that the water dispenser body 20 can provide drinking water at a constant temperature.

[0048] For example, combined Figure 1As shown, in the cooling mode of the air conditioner body 10, the first heat exchange circuit 204 is connected to the refrigerant circuit (refrigerant input end) on one side of the electronic expansion valve 100. The refrigerant is diverted by the first heat exchange circuit 204 before entering the electronic expansion valve 100. The high-temperature and high-pressure refrigerant passes through the first heat exchange circuit 204 to exchange heat with the water in the hot water tank 200. The second heat exchange circuit 210 is connected to the refrigerant circuit (refrigerant output end) on the other side of the electronic expansion valve 100. After flowing out of the electronic expansion valve 100, the refrigerant is diverted by the second heat exchange circuit 210. The low-temperature and low-pressure refrigerant passes through the second heat exchange circuit 210 to exchange heat with the water in the cold water tank 202.

[0049] Combine Figure 2 As shown, after the air conditioner body 10 switches from cooling mode to heating mode, the refrigerant flows in the reverse direction. Because the connection positions between the first heat exchange circuit 204, the electronic expansion valve 100, and the second heat exchange circuit 210 are fixed, the refrigerant flowing through the first heat exchange circuit 204 becomes low-temperature and low-pressure, while the refrigerant flowing through the second heat exchange circuit 210 becomes high-temperature and high-pressure. The conversion component 30 responds to the mode switching of the air conditioner body 10, switching the water tank for heat exchange with the first heat exchange circuit 204 and the second heat exchange circuit 210, so that the water tank for heat exchange with the first heat exchange circuit 204 becomes the cold water tank 202, and the water tank for heat exchange with the second heat exchange circuit 210 becomes the hot water tank 200. The refrigerant in the low-temperature and low-pressure state flowing through the first heat exchange circuit 204 is heat exchanged with the water in the cold water tank 202, and the refrigerant in the high-temperature and high-pressure state flowing through the second heat exchange circuit 210 is heat exchanged with the water in the hot water tank 200, so that the hot water tank 200 constantly provides hot water and the cold water tank 202 constantly provides cold water.

[0050] Compared to related technologies, the heating and cooling states of the hot water tank 200 and the cold water tank 202 do not change with the cooling or heating mode of the air conditioner body 10, improving the stability of the water dispenser body 20. By ensuring that the water tanks constantly provide hot or cold water, the need to heat the water in the tanks from low to high temperatures and back again after the water tanks change state is avoided, thus reducing unnecessary energy waste and further lowering energy consumption. Furthermore, by ensuring that the water tanks constantly provide hot or cold water, the water tanks avoid switching between heating and cooling modes, extending the service life of the water tanks and the water dispenser body 20.

[0051] Optionally, combined Figure 1 and Figure 2As shown, the water dispenser body 20 further includes a first heat exchanger 218 and a second heat exchanger 220. The first heat exchanger 218 is disposed in the hot water tank 200 for exchanging heat with the hot water tank 200. The second heat exchanger 220 is disposed in the cold water tank 202 for exchanging heat with the cold water tank 202. The first heat exchange circuit 204 is in communication with one of the first heat exchanger 218 and the second heat exchanger 220, and the second heat exchange circuit 210 is in communication with the other of the first heat exchanger 218 and the second heat exchanger 220. The switching element 30 is configured to switch the heat exchanger in communication with the first heat exchange circuit 204 or the second heat exchange circuit 210 in response to switching the air conditioner body 10 between cooling mode and heating mode.

[0052] In this embodiment, the hot water tank 200 and the cold water tank 202 are each provided with a first heat exchanger 218 and a second heat exchanger 220. The first heat exchanger 218 is used to transfer heat carried by the first heat exchanger to the water in the hot water tank 200, thereby heating the water. The second heat exchanger 220 is used to absorb heat from the cold water tank 202, lowering the water temperature and producing cold water. The first heat exchange circuit 204 is connected to one of the first heat exchanger 218 and the second heat exchanger 220, while the second heat exchange circuit 210 is connected to the other of the first heat exchanger 218 and the second heat exchanger 220. When the air conditioner is operating in cooling mode or heating mode, the first heat exchanger 218 and the second heat exchanger 220 are used to transfer refrigerant in a high-temperature, high-pressure state or a low-temperature, low-pressure state to the first heat exchanger 218 and the second heat exchanger 220, providing a heat source and a cold source for the water dispenser body 20, thereby reducing the power demand of the water dispenser body 20. In this embodiment, the conversion element 30 switches the water tank for heat exchange with the first heat exchange circuit 204 and the second heat exchange circuit 210 in response to the switching of the air conditioner body 10 between the cooling mode and the heating mode, which refers to switching the heat exchanger connected to the first heat exchange circuit 204 and the second heat exchange circuit 210.

[0053] In this embodiment, when the first heat exchange circuit 204 is connected to the first heat exchanger 218, the refrigerant enters the first heat exchange circuit 204 from the refrigerant circuit through the refrigerant input end of the first heat exchange circuit 204, flows into the first heat exchanger 218 through the first heat exchange circuit 204 for heat exchange, then flows out of the first heat exchanger 218, and then flows back into the refrigerant circuit through the refrigerant output end of the first heat exchange circuit 204. At the same time, the second heat exchange circuit 210 is connected to the second heat exchanger 220. The refrigerant enters the second heat exchange circuit 210 from the refrigerant circuit through the refrigerant input end of the second heat exchange circuit 210, flows into the second heat exchanger 220 through the second heat exchange circuit 210 for heat exchange, then flows out of the second heat exchanger 220, and then flows back into the refrigerant circuit through the refrigerant output end of the second heat exchange circuit 210.

[0054] In this embodiment, when the first heat exchange circuit 204 is connected to the second heat exchanger 220, the refrigerant enters the first heat exchange circuit 204 from the refrigerant circuit through the refrigerant input end of the first heat exchange circuit 204, flows through the first heat exchange circuit 204 into the second heat exchanger 220 for heat exchange, flows out of the second heat exchanger 220, and then re-enters the refrigerant circuit through the refrigerant output end of the first heat exchange circuit 204. At the same time, the second heat exchange circuit 210 is connected to the first heat exchanger 218. The refrigerant enters the first heat exchange circuit 204 from the refrigerant circuit through the refrigerant input end of the second heat exchange circuit 210, flows through the second heat exchange circuit 210 into the first heat exchanger 218 for heat exchange, then flows out of the first heat exchanger 218, and then re-enters the refrigerant circuit through the refrigerant output end of the second heat exchange circuit 210.

[0055] In this embodiment, the first heat exchanger 218 is disposed in the hot water tank 200, and the second heat exchanger 220 is disposed in the cold water tank 202. The heat exchanger 218 may be placed inside the water tank or installed outside the water tank adjacent to the water tank. This application does not limit the specific positional relationship between the heat exchanger and the water tank, as long as heat exchange can be performed and the desired heat exchange efficiency is achieved.

[0056] Optionally, combined Figure 1 、 Figure 2 and Figure 8 As shown, the conversion element 30 includes a two-position four-way reversing valve 300. The two-position four-way reversing valve is provided in the first heat exchange circuit 204 and the second heat exchange circuit 210. The two-position four-way reversing valve 300 can be switched between a first position in which the first heat exchange circuit 204 exchanges heat with the hot water tank 200 and the second heat exchange circuit 210 exchanges heat with the cold water tank 202 in response to the switching of the air conditioner body 10 between the cooling mode and the heating mode, and a second position in which the first heat exchange circuit 204 exchanges heat with the cold water tank 202 and the second heat exchange circuit 210 exchanges heat with the hot water tank 200.

[0057] The operating principle of the two-position, four-way directional valve 300 is to change the connection state of fluid channels by moving its valve core. When the valve core is in one position, a specific channel is opened, allowing fluid to pass through. When the valve core moves to another position, the original channel is closed and a new channel is opened, changing the direction of fluid flow. The valve core position can be switched by an external control signal (such as an electromagnetic signal, a pneumatic signal, or a mechanical signal).

[0058] In this embodiment, a two-position, four-way reversing valve 300 is introduced as the switching element 30 to ensure rapid switching of the heat exchange path, improving the system's response speed and heat exchange efficiency. In the first position, the two-position, four-way reversing valve 300 causes the first heat exchange circuit 204 to exchange heat with the hot water tank 200, while the second heat exchange circuit 210 exchanges heat with the cold water tank 202. When the air conditioner body 10 switches operating modes (for example, from cooling mode to heating mode), the two-position, four-way reversing valve 300 moves to the second position. At this point, the first heat exchange circuit 204 exchanges heat with the cold water tank 202, while the second heat exchange circuit 210 exchanges heat with the hot water tank 200. By utilizing the two-position, four-way reversing valve 300 to flexibly switch the heat exchange path, the system fully utilizes the waste heat or cooling capacity generated during the cooling or heating process, reduces unnecessary energy consumption, and makes the system more energy-efficient and environmentally friendly.

[0059] Optionally, combined Figures 3 to 7 As shown, the first heat exchange circuit 204 includes a first heat exchange branch 206 and a second heat exchange branch 208. The first heat exchange branch 206 is configured to exchange heat with the hot water tank 200, and the second heat exchange branch 208 is configured to exchange heat with the cold water tank 202. The second heat exchange circuit 210 includes a third heat exchange branch 212 and a fourth heat exchange branch 216. The third heat exchange branch 212 is configured to exchange heat with the hot water tank 200, and the fourth heat exchange branch 216 is configured to exchange heat with the cold water tank 202. The conversion element 30 includes a plurality of solenoid valves 302, which are respectively provided at the refrigerant input end and the refrigerant output end of the first heat exchange branch 206, the second heat exchange branch 208, the third heat exchange branch 212, and the fourth heat exchange branch 216.

[0060] In this embodiment, the first heat exchange circuit 204 includes a first heat exchange branch 206 and a second heat exchange branch 208, and the second heat exchange circuit 210 includes a third heat exchange branch 212 and a fourth heat exchange branch 216 (refer to FIG. Figure 4 and Figure 6As shown, solid arrowed lines indicate the flow direction of the refrigerant in the heat exchange circuit, and dashed arrowed lines indicate the flow direction of the refrigerant in the heat exchange branches. The first heat exchange branch 206 and the third heat exchange branch 212 are both used for heat exchange with the hot water tank 200, while the second heat exchange branch 208 and the fourth heat exchange branch 216 are both used for heat exchange with the cold water tank 202. Solenoid valves 302 are provided at the refrigerant input and output ends of the first, second, third, and fourth heat exchange branches 206, 208, 212, and 216, forming a switching element 30. This allows for opening or closing specific heat exchange branches as needed, controlling the flow direction and flow rate of the refrigerant. This allows for switching between cooling and heating modes of the air conditioner body 10 by switching between the first and second heat exchange circuits 204, 210, and effectively controlling the water tank temperatures.

[0061] Specifically, the first heat exchange circuit 204 is connected to the refrigerant circuit (refrigerant input end) on one side of the electronic expansion valve 100, and the refrigerant is diverted by the first heat exchange circuit 204 before entering the electronic expansion valve 100. The second heat exchange circuit 210 is connected to the refrigerant circuit (refrigerant output end) on the other side of the electronic expansion valve 100, and the refrigerant is diverted by the second heat exchange circuit 210 after flowing out of the electronic expansion valve 100. Figure 3 and Figure 4 As shown, when the air conditioner body 10 is operating in cooling mode, the solenoid valve 302 on the first heat exchange branch 206 is open, the solenoid valve 302 on the second heat exchange branch 208 is closed, the solenoid valve 302 on the third heat exchange branch 212 is closed, and the solenoid valve 302 on the fourth heat exchange branch 216 is open. The high-temperature, high-pressure refrigerant passes through the first heat exchange branch 206 to exchange heat with the water in the hot water tank 200. The low-temperature, low-pressure refrigerant passes through the fourth heat exchange branch 216 to exchange heat with the water in the cold water tank 202.

[0062] Combine Figure 5 and Figure 6 As shown, after the air conditioner 10 switches from cooling mode to heating mode, the refrigerant flows in the reverse direction. In response to the mode switch, the solenoid valve 302 on the first heat exchange branch 206 closes, the solenoid valve 302 on the second heat exchange branch 208 opens, the solenoid valve 302 on the third heat exchange branch 212 opens, and the solenoid valve 302 on the fourth heat exchange branch 216 closes. The high-temperature, high-pressure refrigerant passes through the third heat exchange branch 212 to exchange heat with the water in the hot water tank 200. The low-temperature, low-pressure refrigerant passes through the second heat exchange branch 208 to exchange heat with the water in the cold water tank 202, ensuring a constant supply of hot water from the hot water tank 200 and cold water from the cold water tank 202.

[0063] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 8 As shown, the air conditioner body 10 further includes a compressor 102, an outdoor heat exchanger 104 and an indoor heat exchanger 106. The compressor 102, the outdoor heat exchanger 104, the electronic expansion valve 100 and the indoor heat exchanger 106 are connected in sequence to form a refrigerant circuit.

[0064] In this embodiment, the compressor 102, outdoor heat exchanger 104, electronic expansion valve 100, and indoor heat exchanger 106 are sequentially connected to form a refrigerant circuit, enabling the air conditioner 10 to efficiently perform cooling or heating functions and meet the user's desired indoor temperature. During the cooling process, the indoor heat exchanger 106 acts as an evaporator, and the outdoor heat exchanger 104 acts as a condenser. The compressor 102, serving as the power source for the refrigerant cycle, is responsible for compressing the low-temperature, low-pressure gas refrigerant into a high-temperature, high-pressure gas refrigerant, providing power for the refrigerant's flow and circulation. The high-temperature, high-pressure refrigerant gas exchanges heat with air or water in the outdoor heat exchanger 104, releasing heat and condensing into a high-pressure liquid. The electronic expansion valve 100, located between the outdoor heat exchanger 104 and the indoor heat exchanger 106, acts as a throttling and pressure-reducing device, converting the high-pressure liquid refrigerant into low-pressure wet vapor after passing through the expansion valve and entering the indoor heat exchanger 106. The low-pressure wet steam exchanges heat with the indoor air in indoor heat exchanger 106, absorbing heat and evaporating into a low-temperature, low-pressure gas, thereby lowering the indoor temperature. The low-temperature, low-pressure gas refrigerant then returns to compressor 102 to continue the refrigeration cycle. During the heating process, outdoor heat exchanger 104 acts as an evaporator, and indoor heat exchanger 106 acts as a condenser, with the refrigerant circulating in reverse. This process will not be further described here.

[0065] In some embodiments, combined Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, one end of the first heat exchange loop 204 is communicated with the pipeline between the compressor 102 and the outdoor heat exchanger 104 , and the other end of the first heat exchange loop 204 is communicated with the pipeline between the outdoor heat exchanger 104 and the electronic expansion valve 100 .

[0066] In this embodiment, one end of the first heat exchange loop 204 is connected to the pipeline between the compressor 102 and the outdoor heat exchanger 104, and the other end of the first heat exchange loop 204 is connected to the pipeline between the outdoor heat exchanger 104 and the electronic expansion valve 100. This allows for the following: during the cooling process, as the refrigerant exits the compressor 102 and enters the outdoor heat exchanger 104, a portion of the refrigerant is diverted into the first heat exchange loop 204. After completing heat exchange in the first heat exchange loop 204, the refrigerant rejoins the main flow (refrigerant loop) and enters the electronic expansion valve 100. During the heating process, as the refrigerant exits the electronic expansion valve 100 and enters the outdoor heat exchanger 104, a portion of the refrigerant is diverted into the first heat exchange loop 204.

[0067] In some embodiments, combined Figure 5 and Figure 7 As shown, both ends of the first heat exchange loop 204 are in sequential communication with the pipeline between the outdoor heat exchanger 104 and the electronic expansion valve 100 .

[0068] In this embodiment, the two ends of the first heat exchange loop 204 are sequentially connected to the pipeline between the outdoor heat exchanger 104 and the electronic expansion valve 100. This allows for the following: during the cooling process, when the refrigerant flows out of the outdoor heat exchanger 104 and is about to enter the electronic expansion valve 100, a portion of the refrigerant is diverted into the first heat exchange loop 204. After completing heat exchange in the first heat exchange loop 204, the refrigerant rejoins the main flow (refrigerant loop) and enters the electronic expansion valve 100. During the heating process, when the refrigerant flows out of the electronic expansion valve 100 and is about to enter the outdoor heat exchanger 104, a portion of the refrigerant is diverted into the first heat exchange loop 204. After completing heat exchange in the first heat exchange loop 204, the refrigerant rejoins the main flow (refrigerant loop) and enters the outdoor heat exchanger 104.

[0069] In some embodiments, combined Figure 7 As shown, one end of the second heat exchange loop 210 is connected to the pipeline between the electronic expansion valve 100 and the indoor heat exchanger 106 , and the other end of the second heat exchange loop 210 is connected to the pipeline between the indoor heat exchanger 106 and the compressor 102 .

[0070] In this embodiment, one end of the second heat exchange loop 210 is connected to the pipeline between the electronic expansion valve 100 and the indoor heat exchanger 106, and the other end of the second heat exchange loop 210 is connected to the pipeline between the indoor heat exchanger 106 and the compressor 102. This allows for the following: during the cooling process, when the refrigerant flows out of the electronic expansion valve 100 and is about to enter the indoor heat exchanger 106, a portion of the refrigerant is diverted into the second heat exchange loop 210. After completing heat exchange in the second heat exchange loop 210, the refrigerant rejoins the main flow (refrigerant loop) and enters the compressor 102. During the heating process, when the refrigerant flows out of the compressor 102 and is about to enter the indoor heat exchanger 106, a portion of the refrigerant is diverted into the second heat exchange loop 210. After completing heat exchange in the second heat exchange loop 210, the refrigerant rejoins the main flow (refrigerant loop) and enters the electronic expansion valve 100.

[0071] In some embodiments, combined Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 8 As shown, both ends of the second heat exchange loop 210 are connected to the pipelines between the indoor heat exchanger 106 and the compressor 102 in sequence.

[0072] In this embodiment, both ends of the second heat exchange loop 210 are sequentially connected to the pipeline between the indoor heat exchanger 106 and the compressor 102, so that during the cooling process, when the refrigerant flows out of the indoor heat exchanger 106, before entering the compressor 102, part of the refrigerant is diverted into the second heat exchange loop 210. After completing the heat exchange in the second heat exchange loop 210, the refrigerant re-enters the main flow (refrigerant loop) and enters the compressor 102. During the heating process, when the refrigerant flows out of the compressor 102, before entering the indoor heat exchanger 106, part of the refrigerant is diverted into the second heat exchange loop 210. After completing the heat exchange in the second heat exchange loop 210, the refrigerant re-enters the main flow (refrigerant loop) and enters the indoor heat exchanger 106.

[0073] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 8 As shown, the air conditioner body 10 further includes a four-way valve 108. The four ports of the four-way valve 108 are connected to the refrigerant input end and the refrigerant output end of the indoor heat exchanger 106, the outdoor heat exchanger 104, and the compressor 102 respectively.

[0074] Four-way valve 108 is a control valve with four ports. In this embodiment, the four ports of four-way valve 108 are connected to the refrigerant output of indoor heat exchanger 106, the refrigerant input of outdoor heat exchanger 104, the refrigerant input of compressor 102, and the refrigerant output of compressor 102, respectively. Four-way valve 108 switches the air conditioner 10 between cooling and heating modes by changing the flow direction of the refrigerant.

[0075] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 8 As shown, the air conditioner body 10 further includes a fan 110 . The fan 110 is located around the outdoor heat exchanger 104 .

[0076] In this embodiment, a fan 110 is provided around the outdoor heat exchanger 104 to accelerate the air flow around the outdoor heat exchanger 104, increase the air flow rate on the surface of the outdoor heat exchanger 104, speed up the transfer and dissipation of heat, reduce the temperature of the outdoor heat exchanger 104, improve the condensation efficiency, enhance the heat dissipation effect of the outdoor heat exchanger 104, and enable the refrigerant to release heat faster during the condensation process, thereby improving the efficiency of the entire cycle.

[0077] Optionally, combined Figure 8 and Figure 9 As shown, the air conditioner body 10 further includes a bypass line 112, a first electromagnetic three-way valve 114, and a second electromagnetic three-way valve 116. The bypass line 112 is connected in parallel with the indoor heat exchanger 106. The three ports of the first electromagnetic three-way valve 114 are respectively connected to one end of the bypass line 112, the electronic expansion valve 100, and the indoor heat exchanger 106. The three ports of the second electromagnetic three-way valve 116 are respectively connected to the other end of the bypass line 112, the indoor heat exchanger 106, and the compressor 102.

[0078] In this embodiment, the provision of a first solenoid three-way valve 114, a second solenoid three-way valve 116, and a bypass line 112 allows independent control of the start and stop of the air conditioner body 10 without affecting the water dispenser body 20. Specifically, the on / off states of the first and second solenoid three-way valves 114, 116 are controlled to determine whether the refrigerant enters the indoor heat exchanger 106 or bypasses the indoor heat exchanger 106 via the bypass line 112. By providing the bypass line 112 in parallel with the indoor heat exchanger 106, the refrigerant can flow directly to the next part of the system without having to pass through the indoor heat exchanger 106 for heat exchange. When the first and second solenoid three-way valves 114, 116 direct the refrigerant to the bypass line 112, the indoor heat exchanger 106 stops operating, and thus the air conditioner body 10 stops operating. When the first electromagnetic three-way valve 114 and the second electromagnetic three-way valve 116 guide the refrigerant to the indoor heat exchanger 106 , the indoor heat exchanger 106 operates, that is, the air conditioner body 10 operates.

[0079] Optionally, combined Figures 1 to 8 As shown, the air conditioner body 10 further includes a plurality of solenoid valves 302. The plurality of solenoid valves 302 are respectively disposed at the refrigerant input end and the refrigerant output end of the first heat exchange loop 204 and the second heat exchange loop 210.

[0080] In this embodiment, the refrigerant input end and the refrigerant output end of the first heat exchange circuit 204 and the second heat exchange circuit 210 are both provided with solenoid valves 302 to open or close the heat exchange circuit as needed, or to adjust the refrigerant flow through the first heat exchange circuit 204 and the second heat exchange circuit 210, thereby controlling the start and stop of the water tank of the water dispenser body 20, or the temperature of the water tank, without affecting the air conditioner body 10.

[0081] Optionally, combined Figure 8 As shown, the water dispenser body 20 further includes a warm water tank 222. The warm water tank 222 is spaced apart from the hot water tank 200 and the cold water tank 202.

[0082] In this embodiment, a warm water tank 222 is added to store warm water. Warm water refers to water with a temperature between cold water and hot water. The specific temperature can be set according to user needs, such as between 20-45°C. By setting the warm water tank 222 at intervals from the hot water tank 200 and the cold water tank 202, the heat exchange between water bodies of different temperatures is reduced, and the respective water temperatures are kept stable. In addition, by providing the warm water tank 222, users do not need to wait for the hot water to cool down or mix cold water and hot water, but can directly obtain warm water of a suitable temperature, meeting the needs of immediate drinking and improving the user experience. By adding the warm water tank 222, the water dispenser body 20 can provide water at three different temperatures: cold water, warm water, and hot water, meeting the drinking water preferences and scene requirements of different users, further improving the user experience.

[0083] In some embodiments, combined Figure 8 As shown, the first heat exchange loop 204 and the second heat exchange loop 210 are located on opposite sides of the warm water tank 222 for performing heat exchange with the warm water tank 222 .

[0084] In this embodiment, high-temperature and high-pressure refrigerant and low-temperature and low-pressure refrigerant flow through the first heat exchange circuit 204 and the second heat exchange circuit 210, respectively. By arranging the first heat exchange circuit 204 and the second heat exchange circuit 210 on opposite sides of the warm water tank 222, respectively, when the refrigerant flows through each heat exchange circuit, it can exchange heat with the water in the warm water tank 222, thereby realizing the regulation of the water temperature in the warm water tank 222.

[0085] In some embodiments, the water inlet of the warm water tank 222 is in communication with the water outlets of the hot water tank 200 and the cold water tank 202 .

[0086] In this embodiment, the water inlet end of the warm water tank 222 is connected to the water outlet ends of the hot water tank 200 and the cold water tank 202, so that the warm water tank 222 can simultaneously receive water from the hot water tank 200 and the cold water tank 202, so that the warm water tank 222 can mix hot water and cold water in different proportions as needed to achieve the required warm water temperature, thereby quickly responding to user needs and improving the user's drinking experience.

[0087] Optionally, combined Figures 1 to 8 As shown, the water dispenser body 20 further includes a water storage barrel 224. The water outlet of the water storage barrel 224 is communicated with the water inlet of the hot water tank 200 and the cold water tank 202.

[0088] In this embodiment, a water storage tank 224 is used to store water. The water outlet of the water storage tank 224 is connected to the water inlet of the hot water tank 200 and the cold water tank 202. When the water level in the hot water tank 200 and / or the cold water tank 202 drops to a water level threshold preset by the user or technician, the water in the water storage tank 224 automatically flows into the hot water tank 200 and / or the cold water tank 202 for replenishment, thereby ensuring the continuous water supply of the water dispenser body 20.
