Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an air conditioner. Background Art

[0002] Air conditioning, or air conditioner, refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the ambient air in a building or structure.

[0003] The air conditioner of the prior art usually includes an indoor unit and an outdoor unit. The indoor unit includes an evaporator, and the outdoor unit includes a compressor, a condenser, a drying bottle (or a liquid storage tank), and an expansion valve (or a throttling component). The refrigeration principle of the air conditioner is usually to compress the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant through a compressor, and send it to the condenser for cooling. After cooling, it becomes a medium-temperature and high-pressure liquid refrigerant. The medium-temperature and high-pressure liquid refrigerant enters the drying bottle for filtration and dehumidification. After filtration and dehumidification, the medium-temperature and high-pressure liquid refrigerant is throttled and reduced in pressure by the expansion valve (throttling component) to become a low-temperature and low-pressure gas-liquid mixture (usually more liquid), which absorbs heat in the air through the evaporator and vaporizes into a gaseous state, thereby achieving refrigeration by absorbing heat in the air.

[0004] Air-energy water heater, also known as "air source heat pump water heater", works on a principle similar to that of an air conditioner. It uses electricity to drive the compressor. After the high-pressure liquid working fluid passes through the expansion valve, it evaporates into a gas in the evaporator and absorbs a large amount of heat energy from the air; the gaseous working fluid is compressed by the compressor into a high-temperature and high-pressure liquid, and then enters the condenser to release heat, thereby heating the water in the inner tank.

[0005] However, in the prior art, when the air conditioner is in cooling mode, the indoor unit usually blows out cold air, while the outdoor unit blows out hot air. Since the hot air blown out by the outdoor unit is directly discharged into the atmosphere, the heat of the outdoor unit cannot be effectively utilized, resulting in a waste of energy. Summary of the invention

[0006] The present invention provides an air conditioner, which is used to solve the technical problem in the prior art that the heat of an outdoor unit cannot be effectively utilized, thereby reducing energy waste and improving energy utilization.

[0007] The present invention provides an air conditioner, comprising: an outdoor unit, comprising a condenser and an outdoor unit circuit board; a water heater, comprising an inner tank, the inner tank having a water-containing inner cavity, and having a water inlet and a water outlet, the water inlet being connected with the water outlet through the water-containing inner cavity, the condenser being located in the water-containing inner cavity, so as to transfer the heat of the condenser to the water in the water-containing inner cavity when the air conditioner is in a refrigeration state; a heat transfer device, connected to the outdoor unit circuit board, and extending toward the inner tank.

[0008] In an embodiment of the present invention, one end of the heat transfer device is connected to the outdoor unit circuit board, and the other end of the heat transfer device is located in the water containing cavity.

[0009] In an embodiment of the present invention, the heat transfer device includes at least one heat pipe, one end of the heat pipe is connected to the outdoor unit circuit board, and the other end of the heat pipe is located in the water-containing cavity.

[0010] In an embodiment of the present invention, the heat transfer device further comprises fins arranged on the heat pipe.

[0011] In an embodiment of the present invention, the inner tank includes: a tank shell, a water-containing cavity, a water inlet and a water outlet are arranged on the tank shell; a first partition plate is arranged in the water-containing cavity and divides the water-containing cavity into an upper cavity and a lower cavity, the other end of the heat transfer device is located in the upper cavity, and the water outlet is opened in the cavity wall of the upper cavity; a second partition plate is arranged in the lower cavity and divides the lower cavity into a left cavity and a right cavity, the condenser is located in the left cavity, and the water inlet is opened in the lower cavity wall of the right cavity; a first control valve is located between the upper cavity and the left cavity and is connected to the first partition plate; a second control valve is located between the upper cavity and the right cavity and is connected to the first partition plate; a third control valve is located between the left cavity and the right cavity and is connected to the second partition plate; in the first state, the first control valve, the second control valve and the third control valve are opened; in the second state, the first control valve and the third control valve are closed and the second control valve is opened.

[0012] In an embodiment of the present invention, a controller is further included, which is connected to the first control valve, the second control valve and the third control valve.

[0013] In an embodiment of the present invention, a temperature sensor is also included, which is located in the left cavity and connected to the controller and the condenser. When the temperature sensor detects that the temperature of the condenser is higher than a preset value, the first control valve, the second control valve and the third control valve are opened by the controller. When the temperature sensor detects that the temperature of the condenser is lower than a preset value, the first control valve and the third control valve are closed by the controller and the second control valve is opened.

[0014] In an embodiment of the present invention, a heater is further included and arranged in the upper cavity.

[0015] In an embodiment of the present invention, a heat-insulating layer is also included, covering the outer surface of the gallbladder shell.

[0016] In an embodiment of the present invention, the thermal insulation layer is made of glass wool.

[0017] In the air conditioner of the present invention, the condenser of the outdoor unit is located in the water-containing cavity, and the heat of the condenser can be transferred to the water in the water-containing cavity when the air conditioner is in a cooling state. Thus, the heat released by the condenser can be effectively utilized, energy waste can be reduced, energy utilization rate can be improved, and the technical problem that the heat of the outdoor unit cannot be effectively utilized in the prior art can be solved; and during the operation of the air conditioner, the outdoor unit circuit board will release a large amount of heat. By connecting the heat transfer device to the outdoor unit circuit board and extending it to the inner tank, not only can the outdoor unit circuit board be heat-conducted, but the heat released by the outdoor unit circuit board can also be transferred to the water in the water-containing cavity, which can accelerate the speed of water heating. That is, the heat source of the water in the inner tank is the heat released by the condenser and the heat released by the outdoor unit circuit board.

[0018] It is understandable that if the outdoor unit circuit board is not heat-conducted, then during the operation of the air conditioner, the temperature of the circuit components (such as chips) on the outdoor unit circuit board (or the electronic control system) will be too high, which will cause current limiting and reduce the frequency of the outdoor unit compressor, thereby reducing the cooling capacity of the air conditioner, and in the long run it will also affect the service life of the circuit components.

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the description of this embodiment, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the embodiment.

[0029] Figures 1 to 5 The air conditioner provided by the present invention is shown. As can be seen from the figure, the air conditioner of the present invention includes an outdoor unit 1, a water heater 2 and a heat transfer device 3. The outdoor unit 1 may include a connected condenser 11 and an outdoor unit circuit board 12; the water heater 2 includes an inner tank 21, the inner tank 21 has a water containing cavity 201, and has a water inlet 202 and a water outlet 203, the water inlet 202 is connected to the water outlet 203 through the water containing cavity 201, the condenser 11 is located in the water containing cavity 201, so as to transfer the heat of the condenser 11 to the water in the water containing cavity 201 when the air conditioner is in a cooling state; the heat transfer device 3 is connected to the outdoor unit circuit board 12, and is extended to the inner tank 21.

[0030] like Figure 3As shown, in the air conditioner of the present invention, the condenser 11 of the outdoor unit 1 is located in the water-containing cavity 201, and the heat of the condenser 11 can be transferred to the water in the water-containing cavity 201 when the air conditioner is in a cooling state. Thus, the heat released by the condenser 11 can be effectively used to heat the water, thereby reducing energy waste, improving energy utilization, and solving the technical problem that the heat of the outdoor unit 1 cannot be effectively utilized in the prior art; and during the operation of the air conditioner, the outdoor unit circuit board 12 will release a large amount of heat. By connecting the heat transfer device 3 to the outdoor unit circuit board 12 and extending it to the inner tank 21, not only can the outdoor unit circuit board 12 be heat-conducted, but also the heat released by the outdoor unit circuit board 12 can be transferred to the water in the water-containing cavity 201, which can accelerate the speed of water heating. That is, the heat source of the water in the inner tank 21 is the heat released by the condenser 11 and the heat released by the outdoor unit circuit board 12.

[0031] It is understandable that if the outdoor unit circuit board 12 is not heat-conducted, then during the operation of the air conditioner, the temperature of the circuit components (such as chips) on the outdoor unit circuit board 12 (or the electronic control system) will be too high, which will cause current limiting and reduce the frequency of the compressor of the outdoor unit 1, thereby reducing the cooling capacity of the air conditioner, and in the long run it will also affect the service life of the circuit components.

[0032] In addition, since conventional air conditioners and air-energy water heaters both include a condenser 11, that is, two condensers 11, and the air conditioner of the present invention integrates the function of the water heater 2 and has only one condenser 11, the cost for users to purchase an air conditioner and a water heater 2 (air-energy water heater) separately can be reduced.

[0033] like Figure 3 As shown, further, one end of the heat transfer device 3 is connected to the outdoor unit circuit board 12 , and the other end of the heat transfer device 3 is located in the water containing cavity 201 .

[0034] In specific implementation, during the operation of the air conditioner, the outdoor unit circuit board 12 will release a large amount of heat, and the heat transfer device 3 can transfer the heat from the outdoor unit circuit board 12 to the water containing cavity 201. As a result, the water in the water containing cavity 201 can exchange heat with the heat transferred to the water containing cavity 201 via the outdoor unit circuit board 12, further accelerating the speed at which the water is heated.

[0035] like Figure 3 As shown, further, the heat transfer device 3 includes at least one heat pipe 31 , one end of the heat pipe 31 is connected to the outdoor unit circuit board 12 , and the other end of the heat pipe 31 is located in the water containing cavity 201 .

[0036] In specific implementation, compared with a single copper tube or other heat transfer structure, the heat pipe 31 can improve the heat transfer efficiency, so that the heat of the outdoor unit circuit board 12 is quickly transferred to the water-containing cavity 201, further accelerating the speed of water heating and reducing heat loss during the transfer process.

[0037] It is understandable that the heat pipe 31 is a heat pipe 31 with a liquid wick, and its structure is usually a tube shell and a liquid wick arranged in the tube shell, and the liquid wick is soaked in a liquid phase medium. The principle of the heat pipe 31 is that a layer of a liquid wick with a porous capillary structure is embedded in the inner wall of a closed high-vacuum tube (tube shell) or a cylinder, and the liquid wick is soaked in a liquid phase medium. The heat pipe 31 includes an evaporation section and a condensation section. The external heat source inputs heat in the evaporation section to evaporate and vaporize the liquid phase medium, and then the steam flows to the condensation section for condensation, and the released latent heat of vaporization is sent to the outside, thereby realizing heat transfer. The condensed liquid is retracted into the liquid wick, and mainly relies on the action of capillary force to flow back to the evaporation section, which can complete the automatic circulation of the medium.

[0038] In some embodiments, the heat pipe 31 may be a fully enclosed structure with a right-angle bend, which contains a refrigerant (or liquid phase working medium) inside. The heat pipe 31 may include an evaporation section, an insulation section, and a condensation section connected in sequence. The evaporation section may be installed in the electrical control box of the outdoor unit 1 and contact the vertically placed computer board (outdoor unit circuit board 12). At this time, the refrigerant in the evaporation section vaporizes because it absorbs the high heat of the electrical components (circuit components) of the computer board; the insulation section is mainly used to connect the evaporation section and the condensation section to prevent heat loss. The insulation section usually needs to be treated with thermal insulation; the condensation section is arranged in the water-containing cavity 201 and can exchange heat with the water in the water-containing cavity 201.

[0039] In some embodiments, there may be a plurality of heat pipes 31 , and the plurality of heat pipes 31 may be arranged side by side and spaced apart.

[0040] like Figure 3 As shown, in this embodiment, the heat transfer device 3 may further include fins 32, which are arranged on the heat pipe 31. That is, the heat transfer device 3 may be a tube-fin type.

[0041] Through the above-mentioned structural arrangement, the heat exchange area can be increased, the heat transfer efficiency of the heat pipe 31 can be improved, the speed at which water is heated can be further accelerated, and the heat loss during the transfer process can be reduced.

[0042] like Figure 3 and Figure 4As shown, in one embodiment of the present invention, the inner tank 21 includes a tank shell 200, a first baffle 210, a second baffle 220, a first control valve 230, a second control valve 240 and a third control valve 250, and a water-containing cavity 201, a water inlet 202 and a water outlet 203 are arranged in the tank shell 200; the first baffle 210 can be arranged in the water-containing cavity 201 along the horizontal direction, and divides the water-containing cavity 201 into an upper cavity and a lower cavity, the other end of the heat transfer device 3 is located in the upper cavity, and the water outlet 203 is opened in the cavity wall of the upper cavity; the second baffle 220 can be arranged in the lower cavity along the vertical direction, and divide the lower cavity There are a left chamber and a right chamber, the condenser 11 is located in the left chamber, and the water inlet 202 is opened in the lower chamber wall of the right chamber; the first control valve 230 is located between the upper chamber and the left chamber, and is connected to the first partition 210; the second control valve 240 is located between the upper chamber and the right chamber, and is connected to the first partition 210; the third control valve 250 is located between the left chamber and the right chamber, and is connected to the second partition 220; in the first state, the first control valve 230, the second control valve 240 and the third control valve 250 are opened; in the second state, the first control valve 230 and the third control valve 250 are closed and the second control valve 240 is opened.

[0043] In specific implementation, since users usually use the cooling function of the air conditioner in summer, the air conditioner can be placed in the first state in summer, such as Figure 3 As shown, the first control valve 230, the second control valve 240 and the third control valve 250 are opened, so that the water in the water inlet 202 can flow to the upper chamber through the lower chamber (left chamber and right chamber) and flow out from the water outlet 203. Since the other end of the heat transfer device 3 is located in the upper chamber, and the condenser 11 is located in the left chamber, when the air conditioner is cooling, the heat released by the condenser 11 can be used to heat the water in the left chamber, and the heat released by the outdoor unit circuit board 12 can be transferred to the upper chamber through the heat transfer device 3 to heat the water in the upper chamber. Since users usually use the heating function of the air conditioner in winter, the air conditioner can be placed in the second state in winter, such as Figure 4 As shown, the first control valve 230 and the third control valve 250 are closed and the second control valve 240 is opened, so that the water in the water inlet 202 can flow to the upper chamber through the right chamber and flow out from the water outlet 203. Since the other end of the heat transfer device 3 is located in the upper chamber, the air conditioner can rely on the heat released by the outdoor unit circuit board 12 and transferred to the upper chamber through the heat transfer device 3 when heating, so as to heat the water in the upper chamber. In addition, since the water entering the water containing chamber 201 will not flow into the left chamber, that is, the left chamber is not connected with other chambers (the upper chamber and the right chamber), even if the temperature of the condenser 11 is low, the temperature of the water in the water containing chamber 201 will not be reduced, and the user's experience of using hot water will not be affected, thereby solving the technical problem that the water in the water containing chamber 201 cannot be heated or cannot be heated well in winter.

[0044] It is understandable that in winter, users may use air conditioning for heating to increase the indoor temperature. When the air conditioning is heating, the indoor unit usually emits hot air and the outdoor unit 1 emits cold air. Therefore, the temperature of the condenser 11 is relatively low. Although the heat transfer device 3 can transfer the heat released by the outdoor unit circuit board 12 to the inner tank 21, there is still a technical problem that the water in the water containing cavity 201 cannot or cannot be heated to the temperature required by the user, which affects the user's experience of using hot water.

[0045] In a specific embodiment, a water inlet pipe and a water outlet pipe may be separately provided in the left cavity to exchange heat with the condenser 11 (heat exchanger) in the left cavity to prevent frost when the indoor unit is heating.

[0046] In this embodiment, the first partition plate 210 and the second partition plate 220 may be made of glass fiber, which can reduce the heat conduction of water between two adjacent chambers.

[0047] In some embodiments, the second control valve 240 may not be provided, and the first partition plate 210 may only have a through hole at the location of the second control valve 240 to connect the upper chamber and the right chamber.

[0048] In one embodiment of the present invention, the air conditioner may further include a third state. In the third state, the first control valve 230, the second control valve 240 and the third control valve 250 are all closed. Therefore, it can be used to check the sealing of the inner tank 21 to determine whether there is a sealing problem in the upper cavity or the lower cavity, thereby facilitating maintenance.

[0049] In specific implementation, when it is necessary to check the sealing of the inner tank 21, the air conditioner can be put into the third state, that is, the first control valve 230, the second control valve 240 and the third control valve 250 are closed. Thus, water entering the inner tank 21 through the water inlet 202 can only enter the lower chamber. If there is no leakage in the lower chamber, it means that there is no sealing problem in the lower chamber, which means that there is a sealing problem in the upper chamber, which is convenient for maintenance personnel to determine the location that needs maintenance.

[0050] like Figure 5 As shown, specifically, the air conditioner of the present invention may also include a first tube 4, a second tube 5 and a third tube 6. The first tube 4 and the second tube 5 are vertically penetrated in the first partition 210, the upper chamber is connected with the left chamber through the first tube 4, and the upper chamber is connected with the right chamber through the second tube 5. The first control valve 230 is arranged in the first tube 4, the second control valve 240 is arranged in the second tube 5, and the third tube 6 is horizontally penetrated in the second partition 220, the left chamber is connected with the right chamber through the third tube 6, and the third control valve 250 is arranged in the third tube 6.

[0051] Furthermore, the air conditioner of the present invention may further include a heater, which may be a conventional electric heater and is disposed in the upper cavity.

[0052] During specific implementation, the heater can be used to heat the water in the upper chamber, thereby increasing the heating speed of the water in the upper chamber and solving the technical problem of slow heating speed of the water in the upper chamber.

[0053] In some embodiments, the heater can also be used for thawing, that is, to prevent the water in the water containing cavity 201 from freezing and causing the water heater 2 to fail, so as to meet the user's demand for hot water.

[0054] Furthermore, the air conditioner of the present invention may further include a heat-insulating layer, which may be made of glass wool, and the heat-insulating layer covers the outer surface of the shell 200 .

[0055] During specific implementation, the heat-insulating layer can insulate the water in the water-containing cavity 201 , thereby reducing the heat loss of the water in the water-containing cavity 201 and saving energy.

[0056] In one embodiment of the present invention, the air conditioner of the present invention may further include a controller connecting the first control valve 230, the second control valve 240 and the third control valve 250, wherein the first control valve 230, the second control valve 240 and the third control valve 250 may be solenoid valves.

[0057] In a specific implementation, the controller may open or close the first control valve 230 , the second control valve 240 , and the third control valve 250 , that is, the controller may switch the air conditioner between the first state and the second state.

[0058] In this embodiment, the air conditioner provided by the present invention may also include a temperature sensor, which is located in the left cavity and connected to the controller and the condenser 11, wherein when the temperature sensor detects that the temperature of the condenser 11 is higher than a preset value, the first control valve 230, the second control valve 240 and the third control valve 250 are opened by the controller; when the temperature sensor detects that the temperature of the condenser 11 is lower than a preset value, the first control valve 230 and the third control valve 250 are closed by the controller and the second control valve 240 is opened.

[0059] like Figures 3 to 5As shown, during the specific implementation, the temperature sensor can detect the temperature of the condenser 11, thereby determining whether the air conditioner is in the heating mode or the cooling mode. If the temperature sensor detects that the temperature of the condenser 11 is higher than the preset value, it can be said that the air conditioner is in the cooling mode and the condenser 11 is releasing heat. Therefore, the controller can be used to control the opening of the first control valve 230, the second control valve 240 and the third control valve 250, so that the air conditioner is in the first state, and the heat released by the condenser 11 is used to heat the water in the water-containing cavity 201; if the temperature sensor detects that the temperature of the condenser 11 is lower than the preset value, it can be said that the air conditioner is in the heating mode and the condenser 11 is absorbing heat. Therefore, the controller can be used to control the closing of the first control valve 230 and the third control valve 250 and the opening of the second control valve 240, so that the air conditioner is in the second state, so as to prevent the temperature of the condenser 11 from being too low and lowering the temperature of the water in the water-containing cavity 201, thereby improving the user experience.

[0060] It is understandable that nowadays, energy problems are becoming increasingly severe. In the field of refrigeration, reducing energy consumption and improving energy utilization are issues that are currently being focused on in the air-conditioning industry. When the air conditioner is in cooling mode, while the indoor unit brings a comfortable and cool experience to the user, the hot air blown out by the outdoor unit 1 is directly transmitted to the outdoors, resulting in a waste of energy. To this end, the present invention proposes an air conditioner that can simultaneously meet the user's dual needs of indoor cooling and hot water supply. In addition, in order to alleviate the technical problem of high temperature rise of circuit components in the air conditioner, the present invention also applies heat pipes 31 (heat exchangers) to the outdoor unit circuit board 12 and the water heater 2.

[0061] It can also be understood that, as is well known, during cooling, the indoor unit blows cold air and the outdoor unit 1 blows hot air. In one embodiment of the present invention, the original heat dissipation structure of the outdoor unit 1 that relies on the fan can be removed, and related components such as the water heater 2 can be added. The outdoor unit 1 can be divided into three spaces: an electric control box, a compressor compartment, and a water heater compartment. The water heater compartment includes an inner tank 21 and an insulation layer (glass fiber wool felt) arranged around the inner tank 21. The inner tank 21 contains water that needs to be heated. There are two heating components inside the inner tank 21: the condenser 11 and the condensing section of the heat pipe 31. The condenser 11 is not much different from the existing ones, and refrigerant is stored inside it, participating in the complete refrigeration cycle.

[0062] In addition, the components of the circuit board have very high temperatures when working, and many of them will exceed one hundred degrees Celsius. In the long run, this will cause damage to the components and affect their service life. Moreover, the long-term high temperature of the components will also trigger the shutdown protection, affecting the normal use of the air conditioner and bringing a bad experience to the user. The present invention can not only effectively reduce the temperature rise of the components by adding a heat pipe 31, but also use this part of the heat to heat water and supply hot water to the user to meet the user's usage needs.
