Description

[0001] Technical Field: The present invention relates to a household electrical appliance product used in people's daily life, in particular to a household energy-saving refrigerator. Background Art

[0002] Currently, commonly used household refrigerators, household kitchen air conditioners, household dining room air conditioners, and household heat pump water heaters are all household electrical appliance products that work independently. When they work independently, they only separately utilize the heat energy or cold energy generated by the electrical energy they consume. When a household refrigerator works, the cold energy generated by the electrical energy it consumes is fully utilized, but the heat energy generated simultaneously is dissipated into the air, resulting in waste of heat energy. When the refrigerator is refrigerating, the evaporator will frost. In fact, the frost on the evaporator is also a manifestation of cold energy. However, the refrigerator needs to be defrosted regularly every day. When defrosting, an electric heating wire is used to heat and defrost, consuming electrical energy, thus also causing waste of electrical energy and cold energy; when a household kitchen air conditioner and a dining room air conditioner are refrigerating, the cold energy generated by the electrical energy they consume is fully utilized, but the heat energy generated simultaneously is dissipated into the air, thus also causing waste of heat energy; when a household heat pump water heater works, the heat energy generated by the electrical energy it consumes is fully utilized, but the cold energy generated simultaneously is not utilized, thus also causing waste of cold energy. And during spring, autumn, and winter, its evaporator will frost every day when it works. The frost on the evaporator is also a manifestation of cold energy. However, when it works in the above three seasons, it needs to be defrosted every day. When defrosting, electrical energy is consumed to reverse defrost using the heat energy of hot water, thus also causing waste of electrical energy, cold energy, and heat energy.

[0021] The effects of the present invention are as follows: 1. It is a household appliance product integrating six functions of a refrigerator, a kitchen air conditioner, a dining room air conditioner, a water source heat pump water heater, an air source heat pump water heater, and an electric water heater. This is because the device is provided with a refrigerator refrigeration system, an air conditioner refrigeration system, a converter for the dining room air conditioner and the kitchen air conditioner, a water source heat pump hot water system, an air source heat pump hot water system, and an electric auxiliary heater; 2. When the refrigerator function, the air conditioner function, or the heat pump water heater function in the device is started to work, the released heat energy and cold energy can be fully recovered and reused, and the cold energy during defrosting can also be recovered and reused. Therefore, its energy-saving effect is very remarkable during use. This is because when the refrigerator refrigerates, the condensed high-temperature waste heat energy is absorbed by the water in the heat preservation hot water tank, and the waste heat energy is recovered and utilized. After the waste heat energy is recovered, the condensation pressure during the operation of the refrigerator will be reduced, the load during the operation of the compressor will be reduced, and the power consumption of the refrigerator compressor will also be reduced. At the same time that the waste heat energy is recovered and utilized, the water temperature in the heat preservation hot water tank also rises. Also, because heat pump defrosting is adopted, this defrosting method can recover and utilize the waste cold energy generated during frosting when the refrigerator works and the air source heat pump works. After this waste cold energy passes through the operation of the heat pump, it can be absorbed by the integrated cold energy-heat energy collector. After the integrated cold energy-heat energy collector absorbs the waste cold energy, the temperature of the refrigerator condenser placed in the water container can be lowered, thereby reducing the load during the operation of the refrigerator compressor and also reducing the power consumption of the refrigerator compressor. This not only cancels the electric heating wire defrosting, but also enables the waste cold energy to be recovered and reused. Also, because the energy efficiency of heat pump heating during defrosting is greater than that of pure electric heating, the electric energy during defrosting is also saved, and both the waste heat energy and the waste cold energy are recovered and reused.

The refrigerator compressor 1 is electrically connected to the single-chip microcomputer. When the refrigerator compressor 1 works, after the gaseous refrigerant passes through the first condenser 14, the second heat dissipation evaporation dish 39, the fourth condenser 31, and the condensation radiator 29, it will change from gaseous to liquid and release heat energy. After the liquid refrigerant passes through the filter 32 and the third throttle valve 35, it will evaporate into gaseous in the second evaporator 37 and absorb heat for refrigeration, that is, release cold energy, so that the temperature in the heat-insulating box 38 is extremely low.The air-conditioning refrigeration system is installed in the integrated core mainframe box 46. It is composed of an air-conditioning compressor 7, a second condenser 15, a first heat dissipation evaporator 18, a third condenser 20, a sixth solenoid valve 22, a first throttle valve 24, a steam-cooling heat exchanger 9, and a third solenoid valve 6, which are connected in series in a closed loop in sequence. The air-conditioning compressor 7, the third solenoid valve 6, and the sixth solenoid valve 22 are respectively electrically connected to the single-chip microcomputer. When the air-conditioning compressor 7 operates for refrigeration, after the gaseous refrigerant passes through the second condenser 15, the first heat dissipation evaporator 18, and the third condenser 20, it will change from gaseous to liquid and release heat energy. After the liquid refrigerant passes through the sixth solenoid valve 22 and the first throttle valve 24, it will evaporate into gaseous in the steam-cooling heat exchanger 9 and absorb heat for refrigeration, that is, release cold energy. The cold air containing cold energy is discharged from the dining room air-conditioning air outlet 51 or the kitchen air-conditioning air outlet 52, and the hot air containing heat energy is discharged from the heat dissipation air outlet 53. The water source heat pump hot water system is installed in the integrated core mainframe box 46. It is composed of an air-conditioning compressor 7, a second condenser 15, a first heat dissipation evaporator 18, a third condenser 20, a seventh solenoid valve 23, a second throttle valve 25, and a first evaporator 34, which are connected in series in a closed loop in sequence. The air-conditioning compressor 7 and the seventh solenoid valve 23 are electrically connected to the single-chip microcomputer. When the water source heat pump hot water system heats water, the air-conditioning compressor 7 operates. After the gaseous refrigerant passes through the second condenser 15, the first heat dissipation evaporator 18, and the third condenser 20, it will change from gaseous to liquid and release heat energy. At this time, most of the heat energy will be released by the second condenser 15 installed in the heat preservation hot water tank 12, so that the water temperature in the heat preservation hot water tank 12 rises due to obtaining heat energy. After the liquid refrigerant passes through the seventh solenoid valve 23 and the second throttle valve 25, it will evaporate into gaseous in the first evaporator 34 and absorb the heat energy of the water in the water container 30, so that the water temperature in the water container 30 drops due to refrigeration. The air source heat pump hot water system is installed in the integrated core mainframe box. It is composed of an air-conditioning compressor 7, a second condenser 15, a first heat dissipation evaporator 18, a third condenser 20, a sixth solenoid valve 22, a first throttle valve 24, a steam-cooling heat exchanger 9, and a third solenoid valve 6, which are connected in series in a closed loop in sequence. The air-conditioning compressor 7, the third solenoid valve 6, and the sixth solenoid valve 22 are respectively electrically connected to the single-chip microcomputer. When the air-conditioning compressor 7 operates, after the gaseous refrigerant passes through the second condenser 15, the first heat dissipation evaporator 18, and the third condenser 20, it will change from gaseous to liquid and release heat energy. At this time, most of the heat energy will be released by the second condenser 15 installed in the heat preservation hot water tank 12, so that the water temperature in the heat preservation hot water tank 12 rises due to obtaining heat energy. After the liquid refrigerant passes through the sixth solenoid valve 22 and the first throttle valve 24, it will evaporate into gaseous in the steam-cooling heat exchanger 9 and absorb the heat energy in the air.The electric water heater is installed in the heat-insulated hot water tank 12 and consists of an electric auxiliary heater 11 electrically connected. As long as the electric auxiliary heater 11 is powered on, it will directly convert electrical energy into heat energy, and the water in the heat-insulated hot water tank 12 will be heated up after obtaining the heat energy. The integrated cold energy-heat energy collector is installed in the water container 30 and consists of a fourth condenser 31 and a first evaporator 34. When the refrigerator compressor 1 operates, the water in the water container 30 can absorb the waste heat energy released by the fourth condenser 31, thereby causing the surface temperature of the fourth condenser 31 to drop and the condensation pressure in the refrigerator refrigeration system to drop, and the power consumption during the operation of the refrigerator compressor 1 will be reduced. When the water source heat pump operates, the first evaporator 34 in the water container 30 can absorb the heat in the water. After the heat in the water in the water container 30 decreases, the temperature will drop, which will also reduce the power consumption during the operation of the refrigerator compressor 1 and reduce the power consumption of the refrigerator compressor 1. The refrigerator defrosting cold evaporator is installed in the insulation box 38 and consists of a fifth condenser 36 and a second evaporator 37. When the refrigerator compressor 1 operates, the second evaporator 37 will absorb heat and release cold energy. The cold energy released by the second evaporator 37 can ensure the low temperature required for refrigerator freezing and freshness preservation. When the cold energy released by the second evaporator 37 lasts for too long, frost will form on the surface of the second evaporator 37. At this time, defrosting needs to be carried out by relying on the fifth condenser 36 in the refrigerator heat pump defrosting system. The refrigerator heat pump defrosting system is installed in the integrated core main engine box 46 and consists of an air-conditioning compressor 7, a second condenser 15, a first heat dissipation evaporator 18, an eighth solenoid valve 26, a fifth condenser 36, a second one-way valve 33, a second throttle valve 25, and a first evaporator 34 connected in series in a closed loop in sequence. The air-conditioning compressor 7 and the eighth solenoid valve 26 are electrically connected to the single-chip microcomputer. When the refrigerator needs to be defrosted, the air-conditioning compressor 7 starts to operate. After the gaseous refrigerant passes through the second condenser 15, the first heat dissipation evaporator 18, the eighth solenoid valve 26, and the fifth condenser 36, it will change from gaseous to liquid and release heat energy. At this time, part of the condensation heat energy will be released by the fifth condenser 36 installed in the insulation box 38. The heat energy released by the fifth condenser 36 is sufficient to remove the frost on the surface of the second evaporator 37. After the liquid refrigerant passes through the second one-way valve 33 and the second throttle valve 25, it will evaporate into a gaseous state in the first evaporator 34 and absorb the heat in the water in the water container 30, and cool the water in the water container 30 again. This will also reduce the power consumption during the operation of the refrigerator compressor 1 and reduce the power consumption of the refrigerator compressor 1.The heat collector is installed in the insulated hot water tank 12 and consists of a first condenser 14, a second condenser 15, and an electric auxiliary heater 11 electrically connected to the single-chip microcomputer. When the refrigerator compressor 1 or the air conditioner compressor 7 starts to work, both the first condenser 14 and the second condenser 15 will release heat energy due to the change of the refrigerant from gaseous state to liquid state. When the electric auxiliary heater 11 is started to work, electrical energy will also be converted into heat energy. After the water in the insulated hot water tank 12 absorbs the heat energy, the water temperature will rise. The air-conditioning heat pump defrosting system is installed in the integrated core host box 46 and consists of an air conditioner compressor 7, a second condenser 15, a fifth solenoid valve 16, a steam-cooling heat exchanger 9, a first check valve 27, a second throttle valve 25, and a first evaporator 34 connected in series in a closed loop. The air conditioner compressor 7 and the fifth solenoid valve 16 are electrically connected to the single-chip microcomputer. When the air-source heat pump hot water system is used to heat water in spring, autumn, and winter, frost will form on the surface of the steam-cooling heat exchanger 9. At this time, defrosting is required. When defrosting is needed, the air conditioner compressor 7 starts to work. After the gaseous refrigerant passes through the second condenser 15, the fifth solenoid valve 16, and the steam-cooling heat exchanger 9, it will change from gaseous state to liquid state and release heat energy. At this time, part of the heat energy will be released from the steam-cooling heat exchanger 9, and this heat energy is sufficient to remove the frost on the surface of the steam-cooling heat exchanger 9. After the liquid refrigerant passes through the first check valve 27 and the second throttle valve 25, it will evaporate into gaseous state in the first evaporator 34 and absorb the heat energy of the water in the water container 30, and at the same time cool the water in the water container 30, which will also reduce the power consumption when the refrigerator compressor 1 works and reduce the power consumption of the refrigerator compressor 1. The pressure balancer is connected in parallel to the pipeline connecting the inlet and outlet of the air conditioner compressor 7 and consists of a fourth solenoid valve 8. In order to reduce the starting power and current of the air conditioner compressor 7, before the air conditioner compressor 7 starts to work, the high and low pressures in the refrigeration system need to be balanced. Just charge the fourth solenoid valve 8, and the pressures at the inlet and outlet of the air conditioner compressor can quickly reach balance.The refrigerator refrigeration pressure control system is connected in parallel to the refrigerator refrigeration system. It consists of a first solenoid valve 2, a liquid storage tank 3, a second solenoid valve 4, and a one-way constant pressure device 5. One end of the first solenoid valve 2 is connected in parallel to the suction port of the refrigerator compressor 1, and the other end is connected to one end of the liquid storage tank 3. The other end of the liquid storage tank 3 is connected to one end of the second solenoid valve 4 and the one-way constant pressure device 5 connected in parallel. The other ends of the solenoid valve 4 and the one-way constant pressure device 5 connected in parallel are connected in parallel to the middle of the first condenser 14 and the second heat dissipation evaporator 39. The first solenoid valve 2, the second solenoid valve 4 are electrically connected to the single-chip microcomputer. When the high pressure during the operation of the refrigerator compressor 1 is too high, the excess refrigerant will be temporarily stored in the liquid storage tank 3 through the one-way constant pressure device 5. When the high pressure during the operation of the refrigerator compressor 1 is too low, the refrigerant stored in the liquid storage tank 3 will be released to the refrigerator refrigeration system through the first solenoid valve 2 and the second solenoid valve 4, which can ensure that the refrigerator compressor 1 operates under the normal pressure of the refrigerator refrigeration system. The fresh-keeping cold energy transmission system is arranged between the integrated core main engine box 46 and the fresh-keeping and heat-insulating box 49. It is composed of a fresh-keeping cold air upper ventilation duct 43 and a fresh-keeping cold air lower ventilation duct 45 embedded in the fresh-keeping and heat-insulating box 49, which are connected to the heat-insulating box 38 embedded in the integrated core main engine box. When the temperature in the fresh-keeping and heat-insulating box 49 is higher than the fresh-keeping temperature, the refrigerator compressor 1 starts to refrigerate. The third fan 47 continuously transports the cold energy in the heat-insulating box 38 to the fresh-keeping and heat-insulating box 49 until the fresh-keeping and heat-insulating box 49 reaches the fresh-keeping temperature. The freezing cold energy transmission system is arranged between the integrated core main engine box 46 and the freezing and heat-insulating box 50. It is composed of a freezing cold air upper ventilation duct 42 and a freezing cold air lower ventilation duct 44 embedded in the freezing and heat-insulating box 50, which are connected to the heat-insulating box 38 embedded in the integrated core main engine box. When the temperature in the freezing and heat-insulating box 50 is higher than the freezing temperature, the refrigerator compressor 1 refrigerates. The fourth fan 48 continuously transports the cold energy in the heat-insulating box 38 to the freezing and heat-insulating box 50 until the freezing and heat-insulating box 50 reaches the freezing temperature. The converter for the dining room air conditioner and the kitchen air conditioner is arranged in the integrated core main engine box 46. It consists of a wind direction motor 40 electrically connected to the single-chip microcomputer. When using the air conditioner for refrigeration in summer, only by charging or powering off the wind direction motor 40, it is possible to choose to blow the cold air to the air outlet 52 of the kitchen air conditioner or to the air outlet 51 of the dining room air conditioner.The water system is installed in the integrated core mainframe box body 46. It consists of a tap water source 19, a first water switch 17, a heat-insulated hot water tank 12, a water outlet faucet 13, a water container 30, and a second water switch 28. The tap water source 19, the first water switch 17, the heat-insulated hot water tank 12, and the water outlet faucet 13 are connected in series in sequence. One end of the water container 30 is connected to the second water switch 28, and the other end of the water container 30 is connected in parallel between the first water switch 17 and the heat-insulated hot water tank 12. When the first water switch 17 and the second water switch 28 are opened, the water in the tap water source 19 will fill the heat-insulated hot water tank 12 and the water container 30. After filling with water, the first water switch 17 and the second water switch 28 are closed. After the heat-insulated hot water tank 12 absorbs heat energy and the water temperature rises, only by turning on the first water switch 17, hot water can flow out from the water outlet faucet 13. The single-chip microcomputer 41 is electrically connected to the refrigerator compressor 1, the air conditioner compressor 7, the first solenoid valve 2, the second solenoid valve 4, the third solenoid valve 6, the fourth solenoid valve 8, the fifth solenoid valve 16, the sixth solenoid valve 22, the seventh solenoid valve 23, the eighth solenoid valve 26, the first blower 10, the second blower 21, the third blower 47, the fourth blower 48, the first temperature probe 54, the second temperature probe 55, the third temperature probe 56, the fourth temperature probe 57, the fifth temperature probe 58, the electric auxiliary heater 11, and the wind direction motor 40. It receives the data signals from each terminal, processes them, and issues instructions to each terminal to make the entire system operate normally.

[0025] The working process of this energy-saving refrigerator is as follows: After the refrigerator compressor in the refrigeration system of this device starts to work, the evaporator 37 will enable the insulation box 38 to obtain sufficient low-temperature cold energy. This low-temperature cold energy is respectively transported to the fresh-keeping insulation box body 49 and the freezing insulation box body 50 through the fans 47 and 48 in the cold energy transmission system, so that the fresh-keeping insulation box body 49 reaches the fresh-keeping temperature and the freezing insulation box body 50 reaches the freezing temperature. At the same time, the water in the heat preservation hot water tank 12 recycles the waste heat energy of the condenser 14 when the refrigerator is working. After recycling the condensed waste heat energy, the water temperature in the heat preservation hot water tank 12 will rise; After the air-conditioning compressor in the air-conditioning refrigeration system of this device starts to work, the steam-cooling heat exchanger 9 will obtain sufficient low-temperature cold energy. This low-temperature cold energy can be respectively transported to the dining room or the kitchen through the fan 10, the wind direction motor 40, the dining room air-conditioning air outlet 51 or the kitchen air-conditioning air outlet 52. At the same time, the water in the heat preservation hot water tank 12 absorbs the waste heat energy of the condenser 15 when the air conditioner is working. After recycling the condensed waste heat energy, the water temperature in the heat preservation hot water tank 12 will rise. When the water temperature rises to the limit high temperature, the excess waste heat energy will be transported to the outside through the fan 21 and the heat dissipation air outlet 53; After the air-conditioning compressor in the water source heat pump hot water system of this device starts to work, the water in the heat preservation hot water tank 12 will absorb the heat energy of the condenser 15, and the water temperature will rise. At the same time, the water in the water container 30 will absorb the low-temperature waste cold energy released by the evaporator 34, which will reduce the water temperature of the water container 30. In this way, both the cold energy and the heat energy are fully utilized; After the air-conditioning compressor in the air source heat pump hot water system of this device starts to work, the steam-cooling heat exchanger 9 will absorb the heat energy in the air, the condenser 15 will release heat energy, and the water in the heat preservation hot water tank 12 will absorb the condensed heat energy of the condenser 15, and the water temperature will rise; After the electric water heater in this device starts to work, as long as the electric auxiliary heater 11 is powered on, it will directly convert electrical energy into heat energy. After the water in the heat preservation hot water tank 12 obtains the heat energy, the water temperature will rise; When the refrigerator in this device needs defrosting, only need to start the refrigerator heat pump defrosting system. After the air-conditioning compressor starts to work, the condensed heat energy released by the condenser 36 is sufficient to remove the frost on the surface of the evaporator 38. The water in the water container 30 will absorb the low-temperature waste cold energy of the evaporator 34, so that the waste cold energy can be recycled and reused. At the same time, the working load of the refrigerator compressor will be reduced and the power consumption will be reduced; When the air source heat pump water heater in this device needs defrosting, only need to start the air-conditioning heat pump defrosting system. After the air-conditioning compressor starts to work, at this time the steam-cooling heat exchanger 9 has the function of a condenser, and the condensed heat energy it releases is sufficient to remove the frost on its surface. The water in the water container 30 will absorb the low-temperature waste cold energy of the evaporator 34, so that the waste cold energy can be recycled and reused. At the same time, the working load of the refrigerator compressor will be reduced and the power consumption will be reduced.
