a second solenoid valve 105, the second solenoid valve 105 being connected in parallel with the first refrigeration circuit 10;
and the processor 106 is used for controlling the first electromagnetic valve 104 to be disconnected and controlling the second electromagnetic valve 105 to be connected when the refrigerator door is detected to be not normally closed and the time length of the refrigerator door is not normally closed to exceed the preset time length, so that the compressor refrigerating system only refrigerates the cold tank of the water dispenser.
Alternatively, the on and off states of the first solenoid valve 104 and the second solenoid valve 105 are controlled by the processor 106.
Fig. 2 is a schematic structural diagram of a compressor refrigeration system under a condition that a refrigerator door is normally closed according to an embodiment of the present invention. Referring to fig. 2, in case that the refrigerator door is normally closed, the processor controls the first solenoid valve 104 to be always in an on state and controls the second solenoid valve 105 to be always in an off state. The first electromagnetic valve 104 and the refrigerator evaporator 103 form a first refrigeration circuit 10, the cold tank evaporator 102 and the compressor 101 are connected in series with the first refrigeration circuit 10, namely when the first refrigeration circuit 10 is conducted, the compressor refrigeration system can refrigerate a cold tank of the water dispenser through the cold tank evaporator 102 and simultaneously refrigerate the refrigerator through the refrigerator evaporator 103, so that simultaneous refrigeration of the refrigerator and the water dispenser is realized.
Fig. 3 is a schematic structural diagram of a compressor refrigeration system in a case where a refrigerator door provided in the first embodiment of the present invention is not normally closed. Referring to fig. 3, the second electromagnetic valve 105 is connected in parallel with the first refrigeration line 10, and is connected in series with the cold tank evaporator 102 and the compressor 101, and when the second electromagnetic valve 105 is turned on, the first electromagnetic valve 104 is turned off, and the compressor refrigeration system only cools the cold tank of the water dispenser through the cold tank evaporator 102, so that independent refrigeration of the water dispenser is realized. That is, the cold tank evaporator 102 and the compressor 101 are located in the main circuit structure of the compressor refrigeration system, the first electromagnetic valve 104 and the refrigerator evaporator 103 are the first branch of the compressor refrigeration system, and the second electromagnetic valve 105 is the second branch of the compressor refrigeration system.
The processor 106 may be a single-chip microcomputer, and may detect a closed state of the refrigerator door, where an abnormal closed state of the refrigerator door may include a case where the refrigerator door is opened or the refrigerator door is virtually closed, and the case where the refrigerator door is virtually closed may be understood as a case where the refrigerator door is not in contact with or virtually in contact with a refrigerator side plate.
Optionally, the preset time period is set to be longer than the opening time period of the refrigerator door when the user daily takes or puts things.
Illustratively, when the refrigerator door is normally closed, the processor controls the first electromagnetic valve 104 to be turned on and controls the second electromagnetic valve 105 to be turned off in the compressor refrigeration system, so that the compressor 101 can simultaneously refrigerate the refrigerator and the cold tank of the water dispenser.

At this time, the refrigerating circuit composed of the compressor 101, the cold tank evaporator 102 and the second electromagnetic valve 105 is turned on, and the compressor 101 only cools the cold tank of the water dispenser through the cold tank evaporator 102, and does not cool the refrigerator any more. When the temperature in the cold tank of the water dispenser reaches the required temperature, the compressor 101 stops working, so that the power consumption waste caused by the fact that the compressor 101 always works due to the fact that the refrigerator door is not normally closed for a long time is avoided, and the risk that water in the cold tank of the water dispenser is frozen and cannot be discharged due to the fact that the required temperature in the water dispenser is generally lower than the required temperature in the refrigerator is avoided.
The compressor refrigerating system provided by the embodiment is applied to a water dispenser integrated with a refrigerator, at least comprises a compressor, a cold tank evaporator and a refrigerator evaporator which are sequentially connected in series from beginning to end, and further comprises a first electromagnetic valve, a second electromagnetic valve and a processor, wherein the first electromagnetic valve is connected in series between the cold tank evaporator and the refrigerator evaporator, so that the first electromagnetic valve and the refrigerator evaporator form a first refrigerating circuit, and the second electromagnetic valve is connected with the first refrigerating circuit in parallel. When the processor detects that the refrigerator door is not normally closed and the time length of the refrigerator door is not normally closed exceeds the preset time length, the first electromagnetic valve is controlled to be disconnected, the second electromagnetic valve is controlled to be connected, the first refrigerating circuit is disconnected, and the compressor refrigerating system only refrigerates the cold tank of the water dispenser. The problems that in the prior art, under the conditions that a refrigerator door is normally opened or the refrigerator door is not normally closed and the like, the temperature cannot be required in the refrigerator, so that the compressor always works to cause power consumption waste, and the freezing risk exists in water in the cold tank of the water dispenser are solved, the effects of preventing the water in the cold tank of the water dispenser from freezing and the power consumption waste of a refrigerating system are achieved, the reliability of the whole refrigerating system of the compressor is improved, and the problems of damage and service life reduction of the compressor caused by the constant operation of the compressor are solved.
Fig. 4 is a schematic structural diagram of another compressor refrigeration system according to a first embodiment of the present invention. Referring to fig. 4, in addition to the above, optionally, the compressor refrigeration system further includes: a cold tank capillary 107, a condenser 108, a dry filter 109 and a refrigerator capillary 110, wherein the refrigerator capillary 110 is connected in series between the first electromagnetic valve 104 and the refrigerator evaporator 103, the cold tank capillary 107 is connected in series between the cold tank evaporator 102 and the compressor 101, the dry filter 109 is connected in series between the cold tank capillary 107 and the compressor 101, and the condenser 108 is connected in series between the dry filter 109 and the compressor 101.
For example, when the first electromagnetic valve 104 is turned on and the second electromagnetic valve 105 is turned off, after the compressor 101 is turned on and operated, the compressor 101 operates to drive the refrigerant to flow in the pipeline. The refrigerant enters the condenser 108 from the exhaust port of the compressor 101 to reduce the heat of the refrigerant, then the moisture in the refrigerant is removed through the drying filter 109, the refrigerant enters the cold tank evaporator 102 after being throttled by the cold tank capillary tube 107, the refrigerant evaporates and absorbs heat, the heat of water in the cold tank is taken away, the water temperature of the water dispenser is reduced, and the refrigerant continues to enter the refrigerator evaporator 103 after being throttled by the refrigerator capillary tube 110 to evaporate and absorb the heat of air in the refrigerator. And finally, the refrigerant returns to the compressor 101 to sequentially circulate and refrigerate the cold tank of the water dispenser and the refrigerator. When the refrigerant circulates, the temperature of the cold tank water and the temperature of the refrigerator space continuously decrease until the processor 106 sends a stop signal to the compressor 101, and the compressor 101 stops operating.
When the first electromagnetic valve 104 is disconnected and the second electromagnetic valve 105 is connected, after the compressor 101 is started to operate, the compressor 101 operates to drive the refrigerant to flow in the pipeline. The refrigerant enters the condenser 108 from the exhaust port of the compressor 101 to reduce the heat of the refrigerant, then the water in the refrigerant is removed through the drying filter 109, the refrigerant enters the cold tank evaporator 102 after being throttled by the cold tank capillary tube 107, the refrigerant evaporates and absorbs heat, the heat of the water in the cold tank of the water dispenser is taken away, the water temperature in the cold tank of the water dispenser is reduced, and finally the refrigerant returns to the compressor 101. The cooling of the cold tank of the water dispenser is carried out in a circulating way in sequence, and when the refrigerant circulates, the water temperature of the cold tank of the water dispenser is continuously reduced until the processor 106 sends a stop signal to the compressor 101, and then the compressor 101 stops running.
Example two
Fig. 5 is a schematic structural diagram of a water dispenser integrated with a refrigerator according to a second embodiment of the present invention, where the water dispenser integrated with a refrigerator includes a water dispenser 200, a refrigerator 300, and a compressor refrigeration system, and the optional compressor refrigeration system further includes, based on the above embodiments, referring to fig. 5:
a micro switch 107 is located on the refrigerator side panel for being in an off state and generating an off signal to be transmitted to the processor 106 when the refrigerator door is not normally closed, and being in an on state and generating an on signal to be transmitted to the processor 106 when the refrigerator door is normally closed.
Illustratively, when the refrigerator door is normally closed, the micro switch 107 is pressed by the refrigerator door to communicate, and a communication signal is generated and transmitted to the processor 106. If the user forgets Guan Bing the door or the refrigerator door is not closed after putting things, the refrigerator door is in an open state, and the micro switch 107 is not touched by the refrigerator door, the micro switch 107 is in a disconnection state, and the micro switch 107 generates a disconnection signal and transmits the disconnection signal to the processor 106. Optionally, the micro switch 107 transmits a status signal to the processor 106 in real time, that is, when the micro switch 107 is connected, a connection signal is transmitted to the processor 106 in real time, and when the micro switch 107 is disconnected, a disconnection signal is transmitted to the processor 106 in real time.
Optionally, the processor 106 is configured to determine that the refrigerator door is not normally closed and the duration of the abnormal closing exceeds the preset duration when the continuous receiving of the disconnection signal and the duration of the receiving exceeds the preset duration are detected, so as to control the first electromagnetic valve 104 to be disconnected and control the second electromagnetic valve 105 to be turned on, so that the compressor refrigeration system only refrigerates the cold tank of the water dispenser; the processor 106 is further configured to control the second electromagnetic valve 105 to be turned off and the first electromagnetic valve 104 to be turned on when receiving the communication signal, so that the compressor refrigeration system can simultaneously refrigerate the refrigerator and the cold tank of the water dispenser.
For example, if the user forgets Guan Bing that the refrigerator door is not closed after taking or putting things, the micro switch 107 is not touched and is in an off state, the micro switch 107 generates an off signal and transmits the off signal to the processor 106 in real time, and the processor 106 determines that the refrigerator door is not normally closed after receiving the off signal. When the processor 106 continuously receives the off signal for a period of time exceeding a preset period of time, it can be determined based on the period of time that the refrigerator door is not normally closed for a preset period of time, and then the processor 106 controls the first electromagnetic valve 104 to be turned off and controls the second electromagnetic valve 105 to be turned on, and at this time, the refrigerating system only refrigerates the cold tank of the water dispenser, and no longer refrigerates the refrigerator. After the temperature required in the water dispenser is reached in the cold tank of the water dispenser, the processor 106 controls the compressor 101 to stop working, so that the power consumption waste caused by the fact that the compressor 101 always works due to the fact that the refrigerator door is not normally closed for a long time is avoided, and the risk that water in the cold tank of the water dispenser is frozen and cannot be discharged due to the fact that the temperature required in the water dispenser is usually lower than the temperature required in the refrigerator is avoided.
After a period of time, when the user finds that the refrigerator door is not normally closed, the micro switch 107 is touched again to press the communication, and the micro switch 107 generates a communication signal to be transmitted to the processor 106 in real time. After the processor 106 receives the communication signal, the second electromagnetic valve 105 is controlled to be disconnected, and the first electromagnetic valve 104 is controlled to be connected, so that the refrigerating system can simultaneously refrigerate the refrigerator and the cold tank of the water dispenser.
According to the technical scheme, the micro switch is arranged on the refrigerator side plate, and when the refrigerator door is normally closed, the micro switch is triggered to be pressed and communicated, and a communication signal is transmitted to the processor in real time; when the refrigerator door is not normally closed, the micro switch is disconnected and transmits a disconnection signal to the processor in real time. The processor controls the on and off states of the first electromagnetic valve and the second electromagnetic valve according to the received on signal or the off signal and the duration of the received off signal, so that the compressor refrigerating system can simultaneously refrigerate the refrigerator and the cold tank of the water dispenser when the refrigerator door is normally closed, and can only refrigerate the cold tank of the water dispenser when the refrigerator door is not normally closed. Through the arrangement of the micro switch, the processor can conveniently judge the closing state of the refrigerator door, and then the whole compressor refrigerating system is controlled.
Example III
Fig. 6 is a schematic diagram of a compressor refrigeration system according to a third embodiment of the present invention. This embodiment is based on the above embodiments, and referring to fig. 6, the compressor refrigeration system further includes: the first temperature controller 111 is located in the refrigerator, and the first temperature controller 111 is configured to send a first signal to the processor 106 to enable the processor 106 to control the compressor 101 to stop working when the first solenoid valve 104 is turned on and the temperature in the refrigerator is detected to reach the first target temperature.
Optionally, the first target temperature is a preset refrigeration temperature required in the refrigerator.
For example, a first target temperature, which is a required refrigeration temperature in the refrigerator, is preset, when the refrigerator door is in a normal closed state, the first solenoid valve 104 is turned on, the second solenoid valve 105 is turned off, the compressor refrigeration system simultaneously cools the refrigerator and the cold tank of the water dispenser, and the first temperature controller 111 is disposed in the refrigerator to detect the temperature in the refrigerator in real time. As the compressor 101 is operated all the time, the temperatures in the refrigerator and the water dispenser are continuously reduced, when the first temperature controller 111 detects that the first target temperature is reached in the refrigerator, a first signal is sent to the processor 106, and after the processor 106 receives the first signal, the compressor 101 is controlled to stop operating, and the whole compressor refrigeration system does not refrigerate the cold tanks of the refrigerator and the water dispenser.
Optionally, the compressor refrigeration system further comprises: the second temperature controller 112 is located in the cold tank, and the second temperature controller 112 is configured to send a second signal to the processor 106 to cause the processor 106 to control the compressor 101 to stop operating when detecting that the temperature in the cold tank reaches the second target temperature when the second electromagnetic valve 105 is turned on.
Optionally, the second target temperature is a preset refrigeration temperature required in the cold tank of the water dispenser.
For example, the required refrigeration temperature in the cold tank of the water dispenser, that is, the second target temperature, is preset, when the refrigerator door is in an abnormal closed state, the first electromagnetic valve 104 is disconnected, the second electromagnetic valve 105 is turned on, and the compressor 101 only cools the cold tank of the water dispenser. The second temperature controller 112 is disposed in the cold tank of the water dispenser, detects the temperature in the cold tank of the water dispenser in real time, and continuously decreases the temperature in the cold tank of the water dispenser as the compressor 101 is operated all the time. When the second temperature controller 112 detects that the second target temperature in the cold tank of the water dispenser is reached, a second signal is sent to the processor 106, and after the processor 106 receives the second signal, the compressor 101 is controlled to stop working, and the compressor refrigerating system does not refrigerate any more.
Optionally, the first target temperature is lower than the second target temperature. When the refrigerator door is not normally closed, the compressor refrigerating system only refrigerates the cold tank of the water dispenser, and the compressor stops working when the second target temperature is reached in the cold tank of the water dispenser, so that the power consumption waste caused by the fact that the compressor 101 always works when the refrigerator door is not normally closed and the refrigerator is not directly reached to the required temperature in the refrigerator is avoided, and the situation that the compressor 101 always works and the water dispenser is frozen when the refrigerator door is not normally closed and the refrigerator is directly not reached to the required temperature is avoided. When the refrigerator door is normally closed, the compressor refrigeration system simultaneously cools the refrigerator and the cold tank of the water dispenser, and only when the first target temperature is reached in the refrigerator evaporator 103, the compressor stops working.
According to the water dispenser refrigerating system provided by the embodiment of the invention, the first temperature controller is arranged in the refrigerator, the second temperature controller is arranged in the cold tank of the water dispenser, and when the compressor refrigerating system simultaneously refrigerates the refrigerator and the cold tank of the water dispenser, the first temperature controller detects that the refrigerator reaches a first target temperature, and sends a first signal to the processor so that the processor controls the compressor to stop working; when the compressor only refrigerates the cold tank of the water dispenser, the second temperature controller detects that the temperature in the cold tank of the water dispenser reaches the second target temperature, and sends a second signal to the processor to enable the processor to control the compressor to stop working, so that the power consumption waste caused by the fact that the compressor always works when the refrigerator door is not normally closed and the compressor always works when the refrigerator door is not always closed is avoided, the situation that the refrigerator always works when the refrigerator door is not always closed and the compressor always works and the ice is formed in the cold tank of the water dispenser is avoided, the reliability of the whole refrigerating system of the compressor is improved, and the problems of damage and service life reduction caused by the fact that the compressor always works are solved.
Note that the above is only a preferred embodiment of the present invention and the technical principle applied.
