Thing compartment 120 starts when providing cold, to maintain the temperature stabilization of the second storing compartment 120 using its cold end cold.Semiconductor
Refrigeration module 240, based on Peltier principle, using semiconductor chilling plate as low-temperature receiver, and semiconductor chilling plate cold junction temperature is passed
It is delivered in storing compartment.
A kind of mode of distribution refrigerant of cooling medium distributor 250 is：In the first storing compartment 110 and the second storing compartment
When 120 temperature exceedes respective turn-on temperature, while starting the first blower fan 213 and controllable air door 223, so that first be steamed
The cold for sending out device 211 sends into the first storing compartment 110 and the second storing compartment 120 simultaneously, and in the temperature of the second storing compartment 120
Degree is reached after design temperature scope, controllable air door 223 is closed, so that the first evaporator 211 stops to the second storing compartment 120
Supply cold.
First throttle device 212 can use electric expansion valve (aperture is controllable), second throttling device in the present embodiment
232 can use capillary.First throttle device 212 can be configured in the first evaporator 211 simultaneously to the first storing compartment
110 and second storing compartment 120 freeze (controllable air door 223 be in opening) when, being arranged to the first aperture makes to feed to
The refrigerant of first evaporator 211 passes through.And only the first storing compartment 110 is freezed (the first blower fan in the first evaporator 211
213 start, and controllable air door 223 is closed) when, being arranged to the second aperture passes through the refrigerant for feeding to the first evaporator, and first
Aperture is more than the second aperture.So as to by adjusting first throttle device 212 so that the first evaporator 211 exports corresponding cold,
Meet different refrigeration needs.
Correspondingly, during first throttle device 212 is adjusted, compressor 260 can also accordingly be adjusted.Pressure
Contracting machine 260 can use frequency-changeable compressor, and be configured to the first evaporator 211 simultaneously to the first storing compartment 110 with
And second storing compartment 120 run with the first setpoint frequency when freezing (controllable air door 223 open state), in the first evaporator
211 only the first storing compartment 110 is freezed (the first blower fan 213 starts, and controllable air door 223 is closed) when, with second setting frequency
Rate is run, and the first setpoint frequency is higher than the second setpoint frequency.It can be made by adjusting compressor 260 and first throttle device 212
Corresponding cold is exported by the first evaporator 211, different refrigeration needs are met.
Correspondingly, during first throttle device 212 is adjusted, compressor 260 can also accordingly be adjusted.Pressure
Contracting machine 260 can use frequency-changeable compressor, and be configured to the first evaporator 211 simultaneously to the first storing compartment 110 with
And second storing compartment 120 run with the first setpoint frequency when freezing (controllable air door 223 open state), in the first evaporator

The course of work of multi-door refrigerator 10 is introduced control method below in conjunction with the multi-door refrigerator 10 of the present embodiment,
Figure 10 is the schematic diagram of the control method of multi-door refrigerator 10 according to an embodiment of the invention.The controlling party of the multi-door refrigerator 10
Method includes：
It is electric on step S1002, refrigerator 10, initialized, such as carrying out self-inspection to the state of refrigerator 10；
Step S1004, selects operational mode, and operational mode is included to each storing compartment target temperature setup parameter etc.；
Step S1006, it is determined whether use semiconductor refrigerating module 240, such as setting according to user to storing compartment
Whether automatic decision uses semiconductor refrigerating module 240, and such as user is by the first storing compartment 110 and the second storing compartment 120
When being set as the freezing compartment of same target temperature, it can be assumed that semiconductor refrigerating module 240 need not be used, if by second
When storing compartment 120 is set as the alternating temperature compartment different from the first storing compartment 110, it can be assumed that needing to use semiconductor refrigerating
Module 240.
Step S1008, in the case of without using semiconductor refrigerating module 240, in such a way the first storing
The storing compartment 120 of room 110 and second is freezed：It is larger that first throttle device 212 is set to aperture, the first blower fan 213 and pressure
Contracting machine 260 is run with high rotating speed.
Whether step S1010, in the case of using semiconductor refrigerating module 240, judge the temperature of the second storing compartment 120
Higher than turn-on temperature, the turn-on temperature can be set according to the design temperature of the second storing compartment 120, for example, be set higher than
The setting value of constant temperature degree one (such as 3 degree)；
Step S1012, in the case where the temperature of the second storing compartment 120 is higher than turn-on temperature, in such a way to the
One storing compartment 110 and the second storing compartment 120 are freezed：First blower fan 213 starts, and controllable air door 223 is opened；First segment
The stream aperture of device 213 is set to larger, and the first blower fan 213 is run with compressor 260 with high rotating speed；
Step S1014, judges whether the temperature of the second storing compartment 120 is reduced to design temperature scope, the design temperature model
Enclosing can also set according to the design temperature of the second storing compartment 120, for example, be set higher than the setting value of design temperature one (for example
3 degree)；
Step S1016, after the temperature of the second storing compartment 120 is reduced to design temperature scope, in such a way to
One storing compartment 110 and the second storing compartment 120 are freezed：First blower fan 213 starts, the second blower fan 223 is closed；Refrigerant point
Refrigerant is only provided simultaneously to the first evaporator 211 with device 250；Open semiconductor refrigerating module 240；Compressor 260 is with relatively low
Frequency is run, and the first blower fan 213 compared with the slow-speed of revolution to run.
Step S1018, the first storing compartment 110, the second storing compartment 120 difference refrigerating operaton, until between the first storing
The storing compartment 120 of room 110 and second is any be opened or the temperature of the second storing compartment 120 again higher than turn-on temperature (or
Higher than 5 degree of design temperature).
The multi-door refrigerator 10 of the present embodiment, is separated out two storing compartments, wherein one in refrigerator bottom by thermal-insulation baffle plate 150
Individual exclusive use compression-type refrigeration circulation is freezed, and another can select compression-type refrigeration to circulate or semiconductor refrigerating mould
Group is freezed.So as to being required to carry out refrigeration control according to the refrigeration of storing compartment, it is to avoid compressor 260 is frequently opened
Stop.
The multi-door refrigerator 10 of the present embodiment, can be cross side by side combination refrigerator, and two, top storing compartment is used as refrigerator
Room, the storing compartment of bottom two is respectively as refrigerating chamber or temperature-changing chamber, and wherein temperature-changing chamber, which is integrated, uses compression refrigerant and semiconductor
Refrigeration modes are freezed, and meet the use demand of user.
So far, although those skilled in the art will appreciate that detailed herein have shown and described multiple showing for the present invention
Example property embodiment, still, still can be direct according to present disclosure without departing from the spirit and scope of the present invention
