Preferably, the first air outlet 101 and the second air outlet 102 of the present embodiment are disposed at the end of the air outlet section of the cold air duct 10. The number of the air door assemblies 2 is one, the air door assemblies are arranged in the tail end of the air outlet section of the cold air duct 10 and are electrically connected with the control assembly 3, and the air door assemblies 2 can rotate between the first air outlet 101 and the second air outlet 102 which are opened and closed, the first air outlet 101 and the second air outlet 102 which are opened and closed. Therefore, the opening and closing of the first air outlet 101 and the second air outlet 102 can be controlled by only one air door assembly 2, the cold output capacity of the kitchen air conditioner and/or the refrigerator can be controlled, the intelligent control degree is high, and the manufacturing cost of the refrigerating system is further reduced.
In the present embodiment, as shown in fig. 2, the position where the damper assembly 2 opens the first outlet 101 and the second outlet 102 simultaneously is the a position. As shown in fig. 6, the damper assembly 2 is in the position B that closes the first outlet 101 and opens the second outlet 102. As shown in fig. 7, the damper assembly 2 is in the position C that opens the first outlet 101 and closes the second outlet 102. Therefore, according to the working state of the kitchen air conditioner and/or the refrigerator, the control component 3 can control the air door component 2 to flexibly rotate between the position A, the position B and the position C, and therefore the cold output of the kitchen air conditioner and/or the refrigerator is achieved.
As shown in fig. 1-2, in the present embodiment, the refrigeration apparatus 1 further includes a compressor 11, a condenser 12, an evaporator 13 and a first air blowing element 14, the compressor 11 and the first air blowing element 14 are respectively electrically connected to the control component 3, the evaporator 13 is disposed in the air intake section of the cold air duct 10 and is connected to the compressor 11 through the condenser 12, the compressor 11 is configured to deliver compressed refrigerant to the evaporator 13, and radiate heat and condense into a liquid state when flowing through the condenser 12, and the evaporator 13 can absorb heat to cool the surrounding air to generate cold energy. The first air supply member 14 is disposed in the cold air duct 10 and close to the evaporator 13, and is configured to blow cold energy generated by the evaporator 13 through heat absorption to an air outlet section of the cold air duct 10, so as to output cold energy for a kitchen air conditioner and/or a refrigerator. Therefore, the kitchen air conditioner and the refrigerator not only share the three core components of the compressor 11, the condenser 12 and the evaporator 13, but also reduce the electric energy loss caused by a redundant system, further reduce the manufacturing cost and contribute to improving the competitiveness of products compared with the existing refrigerator air conditioner which only shares the compressor and the condenser. In addition, according to the working state of the kitchen air conditioner and the refrigerator, the control component 3 can adjust the rotating speed of the compressor 11, so that the refrigerating device 1 can generate cold energy of different gears.
Specifically, the refrigeration device 1 further includes a second air blowing member 15 electrically connected to the control component 3, and the second air blowing member 15 is disposed near the condenser 12 and used for dissipating heat from the condenser 12. The refrigeration apparatus 1 further includes a filter 16 and a capillary tube 17, the condenser 12 is connected to the evaporator 13 through the filter 16, and the filter 16 is connected to the evaporator 13 through the capillary tube 17.
As shown in fig. 3, further, the refrigeration device further includes an inverter driver 4, the compressor 11 is electrically connected to the control component 3 through the inverter driver 4, and the control component 3 can adjust the rotation speed of the compressor 11 by adjusting the duty ratio of the PWM frequency of the inverter driver 4, so that the refrigeration device 1 generates cooling energy in different gears. In this embodiment, the variable frequency drive 4 is a variable frequency drive board.
In the present embodiment, the PWM frequency refers to the number of times per second that the signal goes from high level to low level and back to high level, and the duty ratio refers to the ratio between the duration of high level and the duration of low level. The variable frequency driving board is a unit for driving the compressor 11 to operate and is responsible for receiving the instruction (realized by serial port signals TX, RX and GND) of the control component 3 and adjusting the rotating speed of the compressor 11; the compressor 11 and damper assembly 2 are controlled electrical devices, the compressor 11 being controlled by the control assembly 3 (via phase drive signal U, V, W) and the damper assembly 2 being controlled by the control assembly 3 (via phase drive signals A +, B +, A-, B-). Therefore, the control component 3 can control the motion of the variable-frequency driving board and the air door component 2 in a linkage manner according to the application scene set by a user.
As can be seen from fig. 4, as the duty cycle of the PWM frequency of the variable frequency drive 4 increases, the corresponding rotational speed of the compressor 11 increases. The maximum speed of the compressor 11 is set to 4000rpm, and since the operation of the compressor 11 is controlled by its phase current, i.e. the speed depends on the current levels of the three phases U, V and W, and the current levels of the U, V and W depend on the duty ratio of the PWM frequency of each phase (e.g. the PWM frequency is fixed to 15KHz, i.e. the period is fixed to 66.6us), the PWM frequency duty ratio of the three phases U, V and W determine the speed of the compressor 11.
When the duty ratio of the PWM frequency of the variable frequency driver 4 is 40%, the corresponding rotating speed of the compressor 11 is 1600rpm, and at the moment, the refrigerating device 1 works at a low gear, namely, the low-gear refrigerating capacity is output by the kitchen air conditioner and/or the refrigerator; when the duty ratio of the PWM frequency of the variable frequency driver 4 is 70%, the corresponding rotating speed of the compressor 11 is 2800rpm, and at the moment, the refrigerating device 1 works at a middle gear, namely, the middle gear refrigerating capacity is output by a kitchen air conditioner and/or a refrigerator; when the duty ratio of the PWM frequency of the variable frequency driver 4 is 100%, the corresponding rotation speed of the compressor 11 is 4000rpm, and at this time, the refrigeration apparatus 1 operates at a high level, that is, it is a high-level cold output of the kitchen air conditioner and/or the refrigerator. Therefore, the frequency conversion technology is adopted as a core, according to the duty ratio of the PWM frequency of the frequency conversion driver 4 and the corresponding rotating speed of the compressor 11, the working gear of the refrigerating device 1 can be at least divided into a low gear, a middle gear and a high gear, so that the control assembly 3 can conveniently control the movement of the air door assembly 2 and flexibly adjust the working gear of the refrigerating device 1 according to the working state of a kitchen air conditioner and a refrigerator, the output cold quantity of the refrigerating device 1 can be matched with the combined use scene of the kitchen air conditioner and the refrigerator, and the power consumption of a kitchen appliance is further reduced.
The refrigeration gears of the kitchen air conditioner comprise a closing gear, a low gear refrigeration and a high gear refrigeration. The operation of the refrigeration system of the present embodiment will be described with reference to fig. 2 and fig. 5-7:
as shown in fig. 6 and 5, when the user only starts the refrigerator, the control component 3 controls the damper component 2 to be in the position B, and controls the refrigeration device 1 to start working to generate cooling capacity, and all cooling capacity in the cold air duct 1 is conveyed to the refrigerator through the second air outlet 102. Because the kitchen air conditioner is in a closed state and only needs to output cold energy for the refrigerator, the cold energy required by the refrigerator can be met by controlling the refrigerating device 1 to work at a low gear so as to reduce the electric energy loss, namely the duty ratio of the PWM frequency of the variable frequency driver 4 is controlled to be 40%, the corresponding rotating speed of the compressor 11 is 1600rpm, and the rotating speed of the compressor 11 reaches 1600rpm at the moment of t 1.
As shown in fig. 2 and 5, at time t2, the user starts the kitchen air conditioner and sets the refrigeration gear of the kitchen air conditioner to be low-gear refrigeration, and the control component 3 controls the damper component 2 to be at position a, so that the refrigeration device 1 operates to generate cold energy which is respectively conveyed to the refrigerator and the kitchen air conditioner through the cold air duct 10. In order to maintain the constant temperature control of the refrigerator, the working gear of the refrigerating device 1 needs to be adaptively improved to the middle gear, that is, the duty ratio of the PWM frequency of the variable frequency driver 4 is controlled to be 70%, the corresponding rotating speed of the compressor 11 is 2800rpm, and the rotating speed of the compressor 11 reaches 2800rpm at the time t3, so that the constant temperature control effect of the refrigerator can be prevented from being affected by the starting of the kitchen air conditioner, and the power consumption of the kitchen appliance is effectively reduced when the rotating speed of the compressor 11 can be adapted to the combined use scene of the kitchen air conditioner and the refrigerator.
As shown in fig. 7 and 5, at time t4, the user sets the refrigeration gear of the kitchen air conditioner to high-gear refrigeration, the control component 3 controls the damper component 2 to be at position a, so that the cooling capacity generated by the operation of the refrigeration device 1 can be respectively transmitted to the refrigerator and the kitchen air conditioner through the cold air duct 10, in order to maintain the refrigerator to be under constant temperature control, the operation gear of the refrigeration device 1 needs to be adaptively increased to high gear, that is, the duty ratio of the PWM frequency of the variable frequency driver 4 is controlled to be 100%, the corresponding rotation speed of the compressor 11 is 4000rpm, and the rotation speed of the compressor 11 reaches 4000rpm at time t5, at this time, the cooling capacity generated by the refrigeration device 1 can meet the requirement of the. In the process, in order to maintain the constant temperature control of the refrigerator and prevent the real-time temperature of the refrigerator from being too low or too high, the cold quantity conveyed to the refrigerator needs to be adaptively adjusted, namely, the control component 3 controls the air door component 2 to intermittently rotate back and forth between the position A and the position C according to the relation between the real-time temperature of the refrigerator and the target temperature, so that the cold quantity output by the refrigerator is adaptively adjusted.
It can be seen that the refrigerating system of this embodiment controls the motion of air door subassembly 2 according to the operating condition of kitchen air conditioner and refrigerator to adopt frequency conversion technique as the core, come the work gear of adaptability regulation refrigerating plant 1 through adjusting the compressor 11 rotational speed in a flexible way, when making refrigerating system can adapt kitchen air conditioner and refrigerator combination use scene, further reduce the power consumption of kitchen electrical apparatus.

Specifically, the refrigeration device 1 includes a cold air duct 10, a semiconductor refrigerator having a cold end and a hot end, and a third air supply member, wherein the semiconductor refrigerator is electrically connected to the control assembly 3, and the cold end of the semiconductor refrigerator is communicated with the cold air duct 10. The third air supply piece is arranged near the semiconductor refrigerator and electrically connected with the control assembly 3, and is used for blowing the refrigerating capacity generated by the cold end of the semiconductor refrigerator to the air outlet section of the cold air duct 10. The control component 3 can flexibly adjust the direct current voltage applied to the semiconductor refrigerator to output the cold energy of different gears, and the working gears of the refrigerating device 1 can be at least divided into three working gears of a low gear, a middle gear and a high gear according to the applied direct current voltage. Therefore, according to the working state of the kitchen air conditioner and/or the refrigerator, the control component 3 can control the movement of the air door component 2 and flexibly adjust the magnitude of the direct-current voltage applied to the air door component, and further the working gear of the refrigerating device 1 can be adaptively adjusted.
In addition, the hot end of the semiconductor refrigerator is communicated with the common flue, and the radiator is arranged on the hot end of the semiconductor refrigerator to prevent the temperature near the hot end of the semiconductor refrigerator from being too high, so that the use performance of the product is improved.

Because the current kitchen air conditioner is in a closed state, the cold output by the refrigerating device 1 is blown to the refrigerator through the second air outlet 102, and in order to realize the constant temperature control of the refrigerator and save electric energy, the refrigerating device 1 is controlled to work at a low gear.
