[0032] The set insulation box 200 is loaded with a heating component 300, and the high-temperature refrigerant output by the compressor 110 is used to heat the water in the first chamber 220 and / or the second chamber 230, so as to recycle the waste heat of the air conditioner 100 and improve the energy utilization efficiency, which not only saves a lot of energy but also reduces the thermal pollution to the environment. The set first chamber 220 and the second chamber 230 realize gradient heating of the water, so that the water in the relatively upper second chamber 230 is hotter, and the hot water rises to the second chamber 230, and the hot water is output from the water outlet pipe 250 on the second chamber 230.

The set electronic three-way reversing valve 400 is used to connect or remove the insulation box 200 from the refrigerant circulation system of the air conditioner, that is, to turn on or off the water heater.

[0033] In some embodiments, the heating assembly 300 includes a heating coil, one end of the heating coil is connected to the outlet of the compressor 110, and the other end of the heating coil is connected to the first inlet 121 of the four-way reversing valve 120. The electronic three-way reversing valve 400 is connected between one end of the heating coil and the other end of the heating coil. The heating coil structure is simple and easy to install.

[0034] In some embodiments, two groups of heating coils are provided, and the first chamber 220 and the second chamber 230 are each provided with a group of heating coils. The two groups of heating coils are connected as a whole. One end of the whole is connected to the outlet of the compressor 110, and the other end of the whole is connected to the first inlet 121 of the four-way reversing valve 120. The electronic three-way reversing valve 400 is connected between one end of the whole and the other end of the whole. The two groups of heating coils can realize zoned heating of the first chamber 220 and the second chamber 230.

[0035] In some embodiments, the heating coil is arranged in a spiral shape.

[0036] In some embodiments, the heating coil is made of copper or stainless steel tubing.

[0037] In some embodiments, a temperature probe 260 is provided on the insulated box 200, and the detection part of the temperature probe 260 extends into the second cavity 230. The temperature probe 260 is used to detect the temperature of the hot water in the second cavity 230. The set temperature probe 260 is used to detect the temperature of the hot water in the second cavity 230. It can be understood that the temperature probe 260 is used in conjunction with the controller. The controller can be a common PLC or computer and other devices. The specific wiring method is a routine choice of technicians in this field.

[0038] In some embodiments, a sewage outlet 270 is disposed at the bottom of the insulated box 200 , and the sewage outlet 270 is connected to the first chamber 220 . The sewage outlet 270 is used to discharge sewage precipitated at the bottom of the first chamber 220 .

[0039] In some embodiments, filter holes 211 are provided on the partition 210 , and the filter holes 211 ensure the purity of water in the second chamber 230 .

[0040] In some embodiments, a support leg 280 is connected to the lower end of the thermal insulation box 200 , and the support leg 280 is provided to facilitate supporting the thermal insulation box 200 .

[0041] It should be noted that when the air conditioner is used for cooling in summer, the exhaust gas of the compressor 110 passes through the electronic three-way reversing valve to the refrigerant outlet valve 500a of the outdoor unit and enters the heating component 300 in the insulated box 200. The refrigerant then enters the refrigerant inlet valve 500b of the outdoor unit through the outlet of the heating component 300, and then enters the first inlet 121 of the four-way reversing valve 120 from the refrigerant inlet valve 500b of the outdoor unit through the one-way valve 500c. The so-called outdoor unit, that is, the outdoor unit of the air conditioner, is the indoor unit loaded with the condenser 130. outdoor unit; then the refrigerant enters the condenser 130 through the first outlet 122 of the four-way reversing valve 120, and the refrigerant enters the evaporator 14 after taking effect in the condenser 130. After the refrigerant in the evaporator takes effect, it returns to the compressor 110 through the second inlet 123 and the second outlet 124 of the four-way reversing valve 120. When heating water, the temperature probe 260 detects the temperature, and the central control device is used to control the fan 600 to be turned off, so as to avoid the fan 600 from discharging hot air to the outside, thereby saving electricity.

[0042] When the air conditioner is used for heating in winter, the exhaust gas of the compressor 110 enters the heating component 300 through the electronic three-way reversing valve 400 and the refrigerant outlet valve 500a of the outdoor unit. The hot refrigerant heats the water in the insulation box 200 in the heating component 300, and then the refrigerant flows out of the heating component 300. The refrigerant reaches the refrigerant inlet valve 500b, the one-way valve 500c and the first inlet 121 of the four-way reversing valve 120 of the outdoor unit in turn, and then the refrigerant enters the evaporator 140 through the second inlet 123 of the four-way reversing valve 120 to heat the indoor room. The refrigerant in the evaporator 140 then enters the condenser 130, and the condenser 130 blows out cold air under the action of the fan 600. At this time, the condenser 130 and the fan 600 act as a cooling system. While the evaporator 140 is heating, hot water can be produced in the insulation box 200.

[0043] It is understandable that in summer, when cooling, the heat discharged by the air conditioner is used, while in winter, when heating, the heat preservation box 200 is needed to share the heat of the evaporator 140, that is, to make full use of the heat.

[0044] In some embodiments, when heating in winter, a set of temperature controllers are set indoors. When the indoor temperature reaches the set temperature, the temperature controller can control the exhaust fan of the evaporator 140 to stop running, so that the heat energy of the air conditioner is directly sent to the heating coil of the insulation box 200 for heating. When the indoor temperature drops to the set temperature, the temperature controller controls the exhaust fan of the evaporator 140 to run to increase the indoor temperature. The electronic three-way reversing valve 400 can also be closed to prevent the refrigerant from entering the heating coil, that is, to turn off the heating function of the water heater. The one-way valve 500c controls the flow direction of the refrigerant so that it does not pass through the heating coil.

[0045] In some embodiments, in the system structure of the insulated box 200, normal pressure tap water is injected into the insulated box from the water inlet pipe 240, heated by the refrigerant heating coil, and then flows out from the water outlet pipe 250 to connect to the user's hot water system for supply. When the water temperature of the water heater reaches the set temperature, the temperature probe 260 detects the temperature, so that the control center automatically closes the electronic three-way reversing valve 400, so that the heating coil is not conducted, that is, the heating function of the water heater is turned off. The temperature probe 260 is added to ensure that the water heater does not produce vaporization, effectively protecting personal safety. A sewage outlet 270 is provided at the bottom of the water tank. When the water heater absorbs heat to a saturated state, the temperature probe 260 automatically turns on the fan 600 on the condenser 130 to cool the system, ensuring that the air conditioning compressor 110 operates normally. When the user does not use the water heater connection, the air conditioning water heater is installed and operated like a general heat pump air conditioner.

[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
