[0003] Existing integrated refrigerators and air conditioners are mostly used at home and blow out the cold air from the refrigerator to function as an air conditioner. Chinese Patent Publication No. CN 215597581 U discloses a technical solution for combining an air conditioner and a refrigerator. However, while integrating the air conditioner and refrigerator into one unit reduces space, this solution still consumes significant energy due to the use of two separate compressors to perform the cooling functions of the air conditioner and refrigerator, respectively.

[0004] In view of this, the inventors propose the following technical solutions. Utility model content:

[0009] Furthermore, in the above technical solution, one end of the second circuit is connected between the refrigerator evaporator and the second switch, and the other end of the second circuit is connected between the refrigerator and the second interface.

[0018] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0019] See Figures 1 to 4As shown, a refrigerator-air conditioner integrated unit with a shared compressor comprises: a compressor 1, a condenser 2, an air-conditioning evaporator 4, a refrigerator evaporator 5, a four-way reversing valve 7, and a three-way valve 8. One end of the condenser 2, the air-conditioning evaporator 4, and the refrigerator evaporator 5 are arranged in parallel via the three-way valve 8, and the other ends of the condenser 2, the air-conditioning evaporator 4, and the refrigerator evaporator 5 are connected to the compressor 1 via the four-way reversing valve 7; a first throttle valve 13 is provided between the air-conditioning evaporator 4 and the three-way valve 8, and a second throttle valve 14 is provided between the refrigerator evaporator 5 and the three-way valve 8. A compressor 1 and a condenser 2 are used in conjunction with a four-way reversing valve 2, a first throttle valve 13 and a second throttle valve 14, so that one compressor 1 can simultaneously meet the air conditioning refrigeration function and the refrigerator refrigeration function. This not only makes the structure more compact and reduces the occupied space, but also has low energy consumption, saves energy and reduces emissions, and can adapt to a variety of occasions. For example: as a mobile air-conditioning refrigerator all-in-one machine, it can be used in outdoor activities such as camping. At this time, an outdoor mobile power supply or electric car can power the device, making it more portable.

[0020] A second circuit 10 is provided between the refrigeration unit 2 and the four-way reversing valve 7, connecting to the refrigerator evaporator 5. A first switch 11 is provided on the second circuit 10, and a second switch 12 is provided between the refrigerator evaporator 5, the air conditioner evaporator 4, and the four-way reversing valve 7. By adding the second circuit 10 and the first and second switches 11 and 12, the air conditioner evaporator 4 and the refrigerator evaporator 5 can operate in independent cooling and heating or simultaneous cooling and heating modes under the coordinated control of the four-way reversing valve 2, the first and second switches 11 and 12. This not only makes the structure more compact and reduces space, but also reduces energy consumption, saves energy, and reduces emissions, making it suitable for a variety of occasions. For example, as a mobile air conditioner and refrigerator all-in-one, it can be used in outdoor activities such as camping. In this case, an outdoor mobile power bank or electric car can power the device, making it more portable.

[0021] The four-way reversing valve 7 includes a first interface and a third interface respectively connected to the inlet and outlet of the compressor 1, a second interface connected to the refrigerator 2, and a fourth interface connected to both the air conditioner evaporator 4 and the refrigerator evaporator 5. A second switch 12 is located between the fourth interface and the air conditioner evaporator 4 and the refrigerator evaporator 5 to facilitate disconnection between the refrigerator evaporator 5 and the fourth interface without blocking the connection between the fourth interface and the air conditioner evaporator 4. One end of the second circuit 10 is connected between the refrigerator evaporator 5 and the second switch 12, and the other end of the second circuit 10 is connected between the refrigerator 2 and the second interface. When the first switch 11 is closed, the refrigerator 2 can be directly connected to the refrigerator evaporator 5.

[0022] One end of the second loop 10 is connected between the refrigerator evaporator 5 and the second switch 12, and the other end of the second loop 10 is connected between the refrigerator 2 and the second interface. When the first switch 11 is closed, the refrigerator 2 can be directly connected to the refrigerator evaporator 5. The air conditioner evaporator 4 is provided with an evaporating fan 41, and the refrigerator 2 is provided with a condensing fan 21.

[0023] The refrigerator evaporator 5 includes at least a refrigeration evaporator 51 and a freezing evaporator 52. One end of the refrigeration evaporator 51 and the freezing evaporator 52 are connected to the three-way valve 8 through a solenoid valve 9. A second throttle valve 14 and a third throttle valve 15 are respectively provided between the solenoid valve 9 and the refrigeration evaporator 51 and the freezing evaporator 52. A drying filter 3 is provided between the refrigerator 2 and the three-way valve 8.

[0024] See Figure 1 The figure shows the first embodiment of the present invention, which operates in the following modes: air conditioning cooling and refrigerator cooling. At this point, the first port of the four-way reversing valve 7 is connected to the second port, the third port is connected to the fourth port, the first switch 11 is open, the second switch 12 is closed, and the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 are all open. Of course, the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 can all be independently controlled to open and close, thereby achieving single air conditioning cooling, single refrigerator cooling, and any combination of two groups. In this operating mode, gas pumped from the compressor 1 enters the condenser 2 through the first and second ports. After being cooled by the condenser 2, the gas is dried and filtered by the drying filter 3 before being diverted through the three-way valve 8 to the air conditioning evaporator 4 and the solenoid valve 9. Finally, it enters the air conditioning evaporator 4 and the refrigerator evaporator 5, achieving air conditioning cooling and refrigerator cooling. The heat-exchanged gas then returns to the compressor 1 through the fourth and third ports of the four-way reversing valve 7, thus achieving a closed-loop circulation of gas.

[0025] See Figure 2The figure shows the second embodiment of the present invention, which operates in the following modes: air conditioning heating and refrigerator heating. At this point, the first port of the four-way reversing valve 7 is connected to the fourth port, the third port is connected to the second port, the first switch 11 is open, the second switch 12 is closed, and the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 are all open. Of course, the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 can all be independently controlled to open and close, thereby enabling heating for the air conditioner alone, heating for the refrigerator alone, and any combination of these two. In this operating mode, gas pumped from the compressor 1 flows through the first and fourth ports into the air conditioner evaporator 4 and the refrigerator evaporator 5. Due to the high temperature of the gas at this point, heating for the air conditioner and refrigerator are achieved. Subsequently, the heat-exchanged gas passes through the solenoid valve 9 and the three-way valve 8, and then through the filter drier 3 into the condenser 2. From the condenser 2, it returns to the compressor 1 through the second and third ports of the four-way reversing valve 7, thus achieving a closed-loop circulation of gas.

[0026] See Figure 3 The figure shows the third embodiment of the present invention, in which the operating mode is: air conditioning cooling, refrigerator heating. At this time, the first port of the four-way reversing valve 7 is connected to the second port, the third port is connected to the fourth port, the first switch 11 is closed, the second switch 12 is open, and the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 are all open. Of course, the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 can all be independently controlled to open and close, achieving single air conditioning cooling or a combination of air conditioning cooling and refrigerator heating. In this working mode, the gas pumped out from the compressor 1 partially flows into the condenser 2 through the first interface and the fourth interface, and partially flows into the refrigerator evaporator 5 through the second circuit 10. Subsequently, the gas flowing into the condenser 2 is refrigerated and flows through the drying filter 3 and then flows into the air-conditioning evaporator 4 from the three-way valve 8. The gas flowing into the refrigerator evaporator 5 is merged with the solenoid valve 9 and then flows into the air-conditioning evaporator 4 through the three-way valve 8, thereby realizing the cooling of the air conditioner. Finally, the gas flowing into the air-conditioning evaporator 5 returns to the compressor 1 through the fourth interface and the third interface of the four-way reversing valve 7, thereby realizing the closed-loop circulation of the gas.

[0027] See Figure 4The fourth embodiment of the present invention is shown in FIG. 1 , which operates in the following modes: heating with the air conditioner and cooling with the refrigerator. At this point, the first port of the four-way reversing valve 7 is connected to the fourth port, the third port is connected to the second port, the first switch 11 is closed, the second switch 12 is open, and the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 are all open. Of course, the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 can all be independently controlled to open and close, enabling either heating with the air conditioner alone or a combination of heating with the refrigerator. In this working mode, the gas pumped out from the compressor 1 flows into the air conditioner evaporator 4 through the first interface and the fourth interface for heating. After heat exchange, the gas flows to the drying filter 3 and the solenoid valve 9 respectively through the three-way valve 8. Subsequently, the gas passing through the drying filter 33 passes through the condenser 2 and returns to the compressor 1 through the second interface and the third interface of the four-way reversing valve 7, while the gas passing through the solenoid valve 8 flows to the refrigerator evaporator 5 for cooling. Subsequently, the gas returns to the compressor 1 from the second circuit 10 through the second interface and the third interface of the four-way reversing valve 7, thereby realizing a closed-loop circulation flow of the gas.

[0028] In summary, in the present invention, through the coordinated control of the four-way reversing valve 7 and the first switch 11 and the second switch 12, a plurality of working modes of the air conditioner and the refrigerator can be realized by using a compressor 1 and a condenser 2, which greatly reduces the required energy consumption. It can not only reduce the power consumption of the household, but also facilitate users to use it outdoors in a portable manner, greatly increasing the scope of application of the equipment.

[0029] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
