Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to an air conditioner. BACKGROUND

[0002] Air conditioner, namely air conditioner, is a device for artificially adjusting and controlling the parameters of air in the environment of building or structure, such as temperature, humidity and flow rate.

[0003] The air conditioner of the prior art usually comprises an indoor unit and an outdoor unit, the indoor unit comprises an evaporator, and the outdoor unit comprises a compressor, a condenser, a drying bottle (or a storage tank) and an expansion valve (or a throttling component). The refrigeration principle of the air conditioner is usually that the compressor compresses the gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, which is sent to the condenser for cooling, and becomes medium-temperature and high-pressure liquid refrigerant after cooling. The medium-temperature and high-pressure liquid refrigerant enters the drying bottle for filtering and dehumidifying. The medium-temperature and high-pressure liquid refrigerant after filtering and dehumidifying is throttled and decompressed into low-temperature and low-pressure gas-liquid mixture (usually liquid) by the expansion valve (throttling component), absorbs heat in the air through the evaporator to vaporize into gas, and thus realizes refrigeration by absorbing heat in the air.

[0004] Air energy water heater, also known as "air source heat pump water heater", has similar working principle with the air conditioner. The compressor is driven by electric energy to operate. The high-pressure liquid working medium is evaporated into gas in the evaporator after passing through the expansion valve, and absorbs a large amount of heat energy from the air. The gaseous working medium is compressed into high-temperature and high-pressure liquid by the compressor, and then enters the condenser to release heat, thereby heating the water in the inner container.

[0005] However, in the prior art, when the air conditioner is cooling, the indoor unit blows cold air, and the outdoor unit blows hot air. Since the hot air blown by the outdoor unit is directly discharged to the atmosphere, the heat of the outdoor unit cannot be effectively utilized, resulting in waste of energy. SUMMARY

[0006] The present application provides an air conditioner to solve the technical problem that the heat of the outdoor unit cannot be effectively utilized in the prior art, reduce the waste of energy, and improve the energy utilization rate.

[0007] The application provides an air conditioner, comprising: an outdoor unit comprising a condenser; and a water heater comprising an inner container, wherein the inner container comprises: a container shell having a water-containing cavity; a first partition plate arranged in the water-containing cavity and separating the water-containing cavity into an upper cavity and a lower cavity, wherein a cavity wall of the upper cavity is provided with a water outlet; a second partition plate arranged in the lower cavity and separating the lower cavity into a left cavity and a right cavity, wherein the first partition plate is provided with a through hole communicating the right cavity and the upper cavity, the condenser is located in the left cavity, a cavity wall of the right cavity is provided with a water inlet, and the water inlet communicates with the water outlet through the water-containing cavity; a first heater arranged in the upper cavity; a first control valve located between the upper cavity and the left cavity and connected with the first partition plate, and used for controlling the opening and closing between the upper cavity and the left cavity; and a second control valve located between the left cavity and the right cavity and connected with the second partition plate, and used for controlling the opening and closing between the left cavity and the right cavity; in a first state, the first control valve and the second control valve are opened; and in a second state, the first control valve and the second control valve are closed, and the first heater is opened.

[0008] In an embodiment of the application, the water heater further comprises a second heater arranged in the left cavity, and in the second state, the first control valve and the second control valve are closed, and the second heater is opened.

[0009] In an embodiment of the application, the second heater is a heating film covering the cavity wall of the left cavity.

[0010] In an embodiment of the application, the outdoor unit further comprises an outdoor unit circuit board, and the air conditioner further comprises a heat transfer device connected with the outdoor unit circuit board and arranged to extend to the inner container.

[0011] In an embodiment of the application, one end of the heat transfer device is connected with the outdoor unit circuit board, and the other end of the heat transfer device is located in the water-containing cavity.

[0012] In an embodiment of the application, the heat transfer device comprises a first heat pipe, one end of the first heat pipe is connected with the outdoor unit circuit board, and the other end of the first heat pipe is located in the left cavity.

[0013] In an embodiment of the application, the heat transfer device further comprises a second heat pipe, one end of the second heat pipe is connected with the outdoor unit circuit board, and the other end of the second heat pipe is located in the upper cavity.

[0014] In an embodiment of the application, the water heater further comprises a temperature sensor for detecting the temperature of the water body in the left cavity, in the second state, and in the state that the temperature of the water body in the left cavity is higher than a preset value, the first control valve and the second control valve are closed, the first heater is opened, and the second heater is closed.

[0015] In an embodiment of the application, the water heater further comprises a controller connected with the first heater, the first control valve, the second control valve and the temperature sensor.

[0016] In an embodiment of the application, the cavity wall of the bottom of the left cavity is further provided with a drain hole, and the drain hole is sealingly provided with a plug.

[0017] The air conditioner provided by the present application has the condenser of the outdoor unit located in the water-containing inner cavity, and the heat released by the condenser can be transferred to the water in the water-containing inner cavity when the air conditioner is cooling, so that the heat released by the condenser can be effectively utilized, the waste of energy is reduced, the energy utilization rate is improved, and the technical problem that the heat of the outdoor unit cannot be effectively utilized in the prior art is solved.

[0018] It can be understood that, in summer, since the user usually uses the cooling function of the air conditioner, the temperature of the condenser is relatively high, and in summer, the air conditioner can be in the first state, i.e., the first control valve and the second control valve are opened, so that the water entering from the water inlet can flow to the upper cavity through the lower cavity (the left cavity and the right cavity) and flow out from the water outlet, i.e., the condenser can heat the water in the entire water-containing inner cavity; in winter, since the user usually uses the heating function of the air conditioner, the temperature of the condenser is relatively low, and in winter, the air conditioner can be in the second state, i.e., the first control valve and the second control valve are closed, and the first heater is opened, so that the condenser only exchanges heat with the closed left cavity, and the condenser can only freeze the water in the left cavity, but cannot freeze the water in the upper cavity and the right cavity, and since the first heater located in the upper cavity is opened in the second state, the user can also use the water heater in winter, i.e., the water entering from the water inlet can flow to the upper cavity through the right cavity and flow out from the water outlet.

[0028] Figs. 1-2 The air conditioner provided by the application is shown, and it can be seen from the figure that the air conditioner provided by the application comprises an outdoor unit 1, a water heater 2, a first heater 3, a first control valve 4 and a second control valve 5. The outdoor unit 1 comprises a condenser 11. The water heater 2 comprises an inner container 21, and the inner container 21 comprises a container shell 211, a first partition plate 212 and a second partition plate 213. The container shell 211 has a water-containing cavity. The first partition plate 212 is arranged in the water-containing cavity and divides the water-containing cavity into an upper cavity 201 and a lower cavity 202. The cavity wall of the upper cavity 201 has a water outlet 215. The second partition plate 213 is arranged in the lower cavity 202 and divides the lower cavity 202 into a left cavity 220 and a right cavity 221. The first partition plate 212 is provided with a through hole 200 communicating the right cavity 221 and the upper cavity 201. The condenser 11 is located in the left cavity 220. The cavity wall of the right cavity 221 is provided with a water inlet 214. The water inlet 214 communicates with the water outlet 215 through the water-containing cavity. The first heater 3 is arranged in the upper cavity 201. The first control valve 4 is located between the upper cavity 201 and the left cavity 220 and is connected with the first partition plate 212, and is used for controlling the on-off between the upper cavity 201 and the left cavity 220. The second control valve 5 is located between the left cavity 220 and the right cavity 221 and is connected with the second partition plate 213, and is used for controlling the on-off between the left cavity 220 and the right cavity 221. In a first state, the first control valve 4 and the second control valve 5 are opened. In a second state, the first control valve 4 and the second control valve 5 are closed, and the first heater 3 is opened.

[0029] The air conditioner provided by the application, the condenser 11 of the outdoor unit 1 is located in the water-containing cavity, and the heat released by the condenser 11 can be transmitted to the water in the water-containing cavity when the air conditioner is cooling, so that the heat released by the condenser 11 can be effectively utilized, the waste of energy is reduced, the energy utilization rate is improved, and the technical problem that the heat of the outdoor unit 1 cannot be effectively utilized in the prior art is solved.

[0030] It can be understood that in summer, since the user usually uses the refrigeration function of the air conditioner, the temperature of the condenser 11 is high (for example, 60 degrees), and in summer, the air conditioner can be in the first state, that is, the first control valve 4 and the second control valve 5 are opened, so that the water entering from the water inlet 214 can flow to the upper cavity 201 through the lower cavity 202 (the left cavity 220 and the right cavity 221) and flow out from the water outlet 215, that is, the condenser 11 can heat the water in the entire water-containing inner cavity; in winter, since the user usually uses the heating function of the air conditioner, the temperature of the condenser 11 is low (for example, 0 degrees), and in winter, the air conditioner can be in the second state, that is, the first control valve 4 and the second control valve 5 are closed, and the first heater 3 is opened, so that the condenser 11 only exchanges heat with the closed left cavity 220, and the condenser 11 can only freeze the water in the left cavity 220, but cannot freeze the water in the upper cavity 201 and the right cavity 221, and since the first heater 3 in the upper cavity 201 is opened in the second state, the user can also use the water heater 2 in winter, that is, the water entering from the water inlet 214 can flow to the upper cavity 201 through the right cavity 221 and flow out from the water outlet 215.

[0031] Specifically, the first heater 3 and the second heater 6 can be heating films, the first heater 3 can cover the cavity wall of the upper cavity 201, and the second heater 6 can cover the cavity wall of the left cavity 220; the first control valve 4 and the second control valve 5 can be electromagnetic valves or ball valves.

[0032] More specifically, the first partition plate 212 and the second partition plate 213 can be made of glass fiber, which can reduce the heat conduction of water between two adjacent cavities (for example, the upper cavity 201 and the left cavity 220).

[0033] Further, the air conditioner of the present application can further comprise a second heater 6 arranged in the left cavity 220, and in the second state, the first control valve 4 and the second control valve 5 are closed, and the second heater 6 is opened.

[0034] In specific implementation, since in winter, the user usually uses the heating function of the air conditioner, the temperature of the condenser 11 is low, and the condenser 11 is located in the left cavity 220 which contains water, if the condenser 11 freezes the water in the left cavity 220, the water will expand after freezing, thus, there is a technical problem that the gall bladder shell 211 is easy to be frozen and damaged (expanded), therefore, in the second state, the second heater 6 arranged in the left cavity 220 can be opened, so as to heat the water in the left cavity 220 through the second heater 6, prevent the water in the left cavity 220 from freezing, and solve the technical problem that the gall bladder shell 211 is easy to be frozen and damaged.

[0035] Still further, the second heater 6 is a heating film covering the cavity wall of the left cavity 220.

[0036] In particular implementation, the heating film covers the cavity wall of the left cavity 220, which can increase the heat exchange area and improve the heating efficiency, and further solve the technical problem that the gall bladder shell 211 is easily frozen.

[0037] In an embodiment of the present application, the outdoor unit 1 further comprises an outdoor unit circuit board 12; and the air conditioner further comprises a heat transfer device 7 connected to the outdoor unit circuit board 12 and extending towards the inner container 21.

[0038] In particular implementation, since a large amount of heat is released from the outdoor unit circuit board 12 during the operation of the air conditioner (cooling or heating), the above structure can conduct heat from the outdoor unit circuit board 12, transfer the heat released from the outdoor unit circuit board 12 to the inner container 21, accelerate the heating speed of the water, i.e., the heat source of the water in the inner container 21 also includes the heat released from the outdoor unit circuit board 12, improve the heat utilization rate, and solve the technical problem of fast power consumption for heating water.

[0039] Specifically, one end of the heat transfer device 7 is connected to the outdoor unit circuit board 12, and the other end of the heat transfer device 7 is located in the water-containing cavity.

[0040] In particular implementation, since a large amount of heat is released from the outdoor unit circuit board 12 during the operation of the air conditioner (cooling or heating), the above structure can conduct heat from the outdoor unit circuit board 12, transfer the heat released from the outdoor unit circuit board 12 to the water-containing cavity, accelerate the heating speed of the water, i.e., the heat source of the water in the water-containing cavity also includes the heat released from the outdoor unit circuit board 12, improve the heat utilization rate, and further solve the technical problem of fast power consumption for heating water.

[0041] More specifically, the heat transfer device 7 comprises a first heat pipe 71, one end of the first heat pipe 71 is connected to the outdoor unit circuit board 12, and the other end of the first heat pipe 71 is located in the left cavity 220.

[0042] In particular implementation, compared with a single copper pipe or other heat transfer structure, the heat pipe can improve the heat transfer efficiency, quickly transfer the heat from the outdoor unit circuit board 12 to the left cavity 220, further accelerate the heating speed of the water, and reduce the heat loss during the transfer process, and further solve the technical problem that the gall bladder shell 211 is easily frozen.

[0043] It can be understood that the heat pipe is a heat pipe with a wick, and the structure thereof is generally a pipe shell and a wick arranged in the pipe shell, and the wick is filled with a liquid-phase working medium. The principle of the heat pipe is that a porous wick is inlaid on the inner wall of a closed and highly vacuumized pipe (pipe shell) or cylinder, the wick is filled with a liquid-phase working medium, the heat pipe includes an evaporation section and a condensation section, an external heat source inputs heat to the evaporation section, the liquid-phase working medium is evaporated and vaporized, then the vapor flows to the condensation section to condense, the released latent heat of vaporization is sent to the outside, so that heat transfer is realized. The condensed liquid is retracted into the wick and flows back to the evaporation section mainly by the action of capillary force, and the automatic circulation of the working medium can be completed.

[0044] In some embodiments, the heat pipe can be fully closed and have a right-angle bend structure, and the inside of the heat pipe contains a refrigerant (or can be referred to as a liquid-phase working medium). The heat pipe can include an evaporation section, an adiabatic section and a condensation section connected in sequence. The evaporation section can be installed in the electric control box of the outdoor unit 1 and in contact with the vertically arranged computer board (outdoor unit circuit board 12). At this time, the refrigerant in the evaporation section is vaporized due to the high heat absorbed by the electrical elements (circuit components) of the computer board; the adiabatic section is mainly used to connect the evaporation section and the condensation section to prevent heat loss, and the adiabatic section usually needs to be heat-insulated; and the condensation section is arranged in the left cavity 220 and can exchange heat with the water in the left cavity 220.

[0045] In an embodiment of the present application, the air conditioner can further include a second heat pipe 72, one end of the second heat pipe 72 being connected to the outdoor unit circuit board 12, and the other end of the second heat pipe 72 being located in the upper cavity 201.

[0046] In specific implementation, since a large amount of heat is released by the outdoor unit circuit board 12 during the operation (cooling or heating) of the air conditioner, the above structure can conduct heat from the outdoor unit circuit board 12, transfer the heat released by the outdoor unit circuit board 12 to the upper cavity 201, and accelerate the heating speed of the water, that is, the heat source of the water in the upper cavity 201 also includes the heat released by the outdoor unit circuit board 12, improves the heat utilization rate, and further solves the technical problem of fast power consumption for heating water. That is, the heat released by the outdoor unit circuit board 12 is mainly transferred to the left cavity 220 and the upper cavity 201.

[0047] In some embodiments, the heat transfer device 7 further includes a first fin and a second fin, the first fin being arranged on the first heat pipe 71, and the second fin being arranged on the second heat pipe 72, so that the heat exchange area can be increased, the heat transfer efficiency can be improved, and the heat utilization rate can be further improved.

[0048] Further, the air conditioner can further include a temperature sensor for detecting the temperature of the water in the left cavity 220. In the second state, and in the state where the temperature of the water in the left cavity 220 is higher than a preset value, the first control valve 4 and the second control valve 5 are closed, and the first heater 3 is turned on and the second heater 6 is turned off.

[0049] In the embodiment, for example, in winter, the air conditioner is usually in the second state, that is, the first control valve 4 and the second control valve 5 are closed, the first heater 3 is opened, and the temperature of the water in the left cavity 220 is above 0 degrees, for example, 10 degrees, so that the water in the left cavity 220 is generally not frozen, and thus the second heater 6 does not need to be opened, and only the heat transfer of the first heat pipe 71 can meet the needs.

[0050] Further, the air conditioner can further include a controller connected to the first heater 3, the first control valve 4, the second control valve 5, and the temperature sensor.

[0051] In the embodiment, the controller can be used for operation, and manual operation is not needed, which is convenient and fast and solves the technical problem of time-consuming and laborious operation.

[0052] In one embodiment of the present application, the cavity wall of the bottom of the left cavity 220 is further provided with a drain hole 216, and the drain hole 216 is sealed with a plug 217.

[0053] In the embodiment, the drain hole 216 can drain the water in the left cavity 220, and the inner container 21 can be conveniently maintained, when maintenance is needed, the plug 217 is removed, the drain hole 216 is exposed, and the water in the left cavity 220 can be drained, so that the weight of the inner container 21 is reduced.

[0054] In some embodiments, the air conditioner of the present application can further include a thermal insulation layer, which can be made of glass wool, and the thermal insulation layer covers the outer surface of the container shell 211.

[0055] In the embodiment, the thermal insulation layer can insulate the water in the water-containing cavity, reduce the heat loss of the water in the water-containing cavity, and save energy.

[0056] It can be understood that nowadays, the energy problem is increasingly severe. In the field of refrigeration, reducing energy consumption and improving energy utilization rate are the problems that are focused on in the current air conditioning industry. When the air conditioner is in the refrigeration mode, the indoor unit brings comfortable and cool experience to the user, while the hot air blown by the outdoor unit 1 is directly spread to the outside, causing waste of energy. Therefore, based on the rich design and development experience in the related industry for many years, and in view of the existing technical means, the present application proposes an air conditioner that can simultaneously meet the dual needs of indoor refrigeration and hot water supply of the user.
