Referring to fig. 1 and 2, fig. 1 is a front view of a refrigerator according to an embodiment of the present application. Fig. 2 is a side view of the refrigerator shown in fig. 1. The embodiment of the application provides a refrigerator 100, the refrigerator 100 comprises a refrigerator body, a door body, a first evaporator 40, a second evaporator 50, an air duct 60, a fan 30 and a controller 90, wherein a storage compartment is arranged in the refrigerator body, the storage compartment comprises a freezing chamber 20 and a refrigerating chamber 10, the freezing chamber 20 is provided with a top 210 and a bottom 220 which are oppositely arranged, and a side 230 and a back 230 which are arranged around the bottom 220, and the back 230 is oppositely arranged with the door body. The first evaporator 40 and the second evaporator 50 are both used for refrigerating the freezing chamber 20, wherein the first evaporator 40 and the second evaporator 50 are connected in parallel, the first evaporator 40 is arranged on the back 230 of the freezing chamber 20, and the second evaporator 50 is arranged on the top 210 of the freezing chamber 20, i.e. the refrigerating direction of the first evaporator 40 is perpendicular to the refrigerating direction of the second evaporator 50. The air duct 60 connects the freezing compartment 20 and the refrigerating compartment 10, and the blower 30 is disposed in the air duct 60 and located in the freezing compartment 20. The controller 90 is electrically connected to the first evaporator 40, the second evaporator 50, and the fan 30, respectively, and the controller 90 is configured to cool the freezing chamber 20 and the refrigerating chamber 10, respectively, by controlling the first evaporator 40, the second evaporator 50, and the fan 30, respectively.

When the refrigerating compartment 10 does not need to be refrigerated and the freezing compartment 20 does need to be refrigerated, the controller 90 controls the blower 30 to stop operating, and the first evaporator 40 and the second evaporator 50 simultaneously refrigerate to refrigerate the freezing compartment 20. According to the embodiment of the application, the air door is not arranged in the air duct 60, namely, the air supply opening of the air duct 60 arranged in the refrigerating chamber 10 is in a normally open state, and when the refrigerating chamber 10 does not need to be refrigerated and the freezing chamber 20 does need to be refrigerated, the fan 30 is closed, so that cold air can be prevented from entering the refrigerating chamber 10. Also, with the blower fan 30 turned off, the first evaporator 40 is disposed at the side of the freezing chamber 20 and the second evaporator 50 is disposed at the top 210 of the freezing chamber 20, so that the first evaporator 40 and the second evaporator 50 simultaneously cool to form an air flow to cool the freezing chamber 20. In addition, when the refrigerating chamber 10 needs to be refrigerated, cool air can be input into the refrigerating chamber 10 by opening the fan 30, so that the embodiment of the application realizes the refrigeration of the refrigerating chamber 10 by controlling the opening and stopping of the fan 30, and realizes the independent refrigeration of the freezing chamber 20 by the first evaporator 40 and the second evaporator 50 under the condition that the fan 30 is stopped and no air door exists, thereby realizing the independent refrigeration of the freezing chamber 20, and saving the cost without arranging an air door.

The air duct 60 includes a first air duct 610, a second air duct 620, and a third air duct 630 sequentially connected, the first air duct 610 is disposed on a side back of the refrigerating chamber 10, the third air duct 630 is disposed on a side back of the freezing chamber 20, and the second air duct 620 is disposed between the refrigerating chamber 10 and the freezing chamber 20.

It will be appreciated that the blower 30 and the first evaporator 40 are both disposed in the third air duct 630, and that the first evaporator 40 is disposed on a side of the blower 30 remote from the refrigerator compartment 10. The cool air of the freezing compartment 20 may be sequentially flowed into the second air duct 620 and the first air duct 610 from the third air duct 630 by the rotation of the blower 30, and then flowed into the refrigerating compartment 10 through the first air duct 610 to cool the refrigerating compartment 10.

Because the second evaporator 50 is disposed at the top 210 of the freezing chamber 20 and the first evaporator 40 and the second evaporator 50 are used for cooling in a matched manner, the first evaporator 40 can be set as a single-row fin evaporator.

It should be noted that, in some embodiments, the second evaporator 50 may be disposed inside the chamber 20, and in other embodiments, the second evaporator 50 may be disposed outside the chamber 20. In particular, when the second evaporator 50 is disposed outside between the freezing chambers 20, the second evaporator 50 may be a plate tube evaporator. When the second evaporator 50 is disposed in the compartment of the freezing compartment 20, the second evaporator 50 may be any type of evaporator other than a plate tube evaporator, for example, one of a wire tube evaporator, a fin evaporator and a roll-bond evaporator, and the specific arrangement may be according to the actual situation, without being particularly limited thereto.

It will be appreciated that the refrigerator 100 includes a liner for insulating the foaming layer, wherein the placement of the second evaporator 50 in the compartment of the freezer compartment 20 means that the second evaporator 50 is disposed inside the liner, not in contact with the foaming layer. The second evaporator 50 being disposed outside between the freezing chambers 20 means that the second evaporator 50 is disposed outside the inner container to be in contact with the foaming layer.

The plate tube evaporator may be as shown in fig. 3, and fig. 3 is a schematic structural diagram of the plate tube evaporator in the refrigerator shown in fig. 1. The plate and tube evaporator includes an evaporation plate 510 and an evaporation coil 520 disposed on the evaporation plate 510. The evaporation plate 510 is formed of an aluminum plate, and heat exchange is performed through the evaporation plate 510, so that the area of the evaporation plate 510 determines the refrigerating capacity of the plate tube evaporator.

It should be noted that, the start temperature and the stop temperature of the freezing chamber 20 may be default temperatures according to the ambient temperature, or may be obtained in combination with the target temperature of the freezing chamber 20 set by the user. The start-up temperature and the stop-up temperature of the refrigerating chamber 10 may be default temperatures of the system according to the ambient temperature, or may be obtained by combining the target temperatures of the refrigerating chamber 10 set by the user, which are not particularly limited herein, and are particularly set according to actual situations.

When the current temperature of the freezing chamber reaches the starting temperature and the current temperature of the refrigerating chamber reaches the stopping temperature, the refrigerating chamber is determined to have the refrigerating requirement, and the refrigerating chamber is determined to have no refrigerating requirement.

When the freezing chamber 20 has a refrigerating demand, the current temperature of the refrigerating chamber 10 is compared with the shutdown temperature of the refrigerating chamber 10, and when the current temperature of the refrigerating chamber 10 reaches the shutdown temperature, it is determined that the freezing chamber 20 has a refrigerating demand and the refrigerating chamber 10 has no refrigerating demand.

204. When the current temperature of the freezing chamber does not reach the starting temperature, and the current temperature of the refrigerating chamber reaches the starting temperature, the refrigerating chamber is determined to have a refrigerating requirement, and the freezing chamber does not have the refrigerating requirement.

Comparing the current temperature of the freezing chamber 20 with the start-up temperature of the freezing chamber 20, and determining that the freezing chamber 20 has no cooling requirement when the current temperature of the freezing chamber 20 does not reach the start-up temperature.

When the freezing chamber 20 has no refrigeration requirement, the current temperature of the refrigerating chamber 10 is compared with the starting temperature of the refrigerating chamber 10, and when the current temperature of the refrigerating chamber 10 reaches the starting temperature, it is determined that the freezing chamber 20 has no refrigeration requirement and the refrigerating chamber 10 has a refrigeration requirement.

In other embodiments, whether the freezing compartment 20 and the refrigerating compartment 10 require cooling is directly acquired according to the acquired control instruction. For example: a first control instruction for controlling the refrigerating compartment 10 and a second control instruction for controlling the freezing compartment 20 are acquired. And determines whether the refrigerating compartment 10 and the freezing compartment 20 have a refrigerating demand according to the first control command and the second control command. If the first control command is that refrigeration is required, determining that the refrigerating chamber 10 has a refrigeration requirement; if the first control command is that refrigeration is not required, it is determined that the refrigeration compartment 10 is not in need of refrigeration. If the second control command is that refrigeration is required, determining that the freezing chamber 20 has a refrigeration requirement; if the second control command is that refrigeration is not required, it is determined that the freezer compartment 20 has no refrigeration requirement.

102. When the refrigerating chamber has a refrigerating requirement, the first evaporator and the fan are controlled to be started to work, and the fan 30 is controlled to supply air to the refrigerating chamber through the air duct so as to control the temperature of the refrigerating chamber.

When the refrigerating chamber 10 has a refrigerating requirement, the first evaporator 40 is controlled to be started to perform refrigeration, the fan 30 is started to rotate, and cold air is input into the refrigerating chamber 10 through the air duct 60 by rotating the fan 30, so that the temperature of the refrigerating chamber 10 is controlled.

In some embodiments, during the cooling process of the refrigerating chamber 10, different cooling schemes can be performed according to the difference between the current temperature and the preset temperature, please continue to refer to fig. 6, and fig. 6 is a schematic flow chart of the control method shown in fig. 4 when the refrigerating chamber has a cooling requirement. The specific flow is as follows:

301. The current temperature of the refrigerating chamber is obtained.

The current temperature of the refrigerating compartment 10 is obtained according to a temperature sensor provided at the refrigerating compartment 10.

302. And if the difference value between the current temperature and the preset temperature is within the threshold value, controlling the first evaporator to refrigerate and controlling the second evaporator to stop working.

The current temperature of the refrigerating compartment 10 and the preset temperature are subjected to a difference process, and when the difference is within a threshold value, the first evaporator 40 is controlled to cool and the second evaporator 50 is controlled to stop operating. That is, when the current cooling intensity is not high, only the first evaporator 40 can be controlled to cool alone, and by controlling the first evaporator 40 to operate alone to cool the refrigerating chamber 10, the power consumption can be reduced, and the electric energy can be saved.

After the first evaporator 40 alone cools for a period of time, if the temperature of the refrigerating compartment 10 reaches the shutdown temperature of the refrigerating compartment 10, the fan 30 and the first evaporator 40 are controlled to stop operating.

303. And if the difference value between the current temperature and the preset temperature is not within the threshold value, controlling the first evaporator and the second evaporator to simultaneously refrigerate so as to refrigerate the refrigerating chamber.

The current temperature of the refrigerating compartment 10 and the preset temperature are subjected to a difference process, and when the difference is not within a threshold value, both the first evaporator 40 and the second evaporator 50 are controlled to be cooled. I.e. when the current refrigeration intensity is high, the first evaporator 40 and the second evaporator 50 are controlled to perform refrigeration in a matched manner. Wherein the first evaporator 40 may be controlled to cool at a third power and the second evaporator 50 may be controlled to cool at a fourth power, the fourth power being less than the third power. That is, when cooling the refrigerating chamber 10, since the cool air is mainly supplied to the channel through the fan 30 to cool the refrigerating chamber 10, and the first evaporator 40 is disposed in the air duct 60 and the first evaporator 40 is located below the fan 30, the first evaporator 40 is mainly used when cooling the refrigerating chamber 10, so that the energy consumption can be reduced. The specific values of the third power and the fourth power are set according to the actual situation, and are not particularly limited herein.

In other embodiments, the cooling power of the first evaporator 40 and the cooling power of the second evaporator 50 may be adjusted in real time according to the current temperature, and are not particularly limited herein.

After the first evaporator 40 and the second evaporator 50 are cooled for a period of time, if the temperature of the refrigerating compartment 10 reaches the shutdown temperature of the refrigerating compartment 10, the fan 30, the first evaporator 40 and the second evaporator 50 are controlled to stop working.

103. When the refrigerating chamber has no refrigerating requirement, the fan is controlled to stop working, and the first evaporator and the second evaporator are controlled to simultaneously refrigerate to form a cold air circulation to refrigerate the freezing chamber.

When the refrigerating compartment 10 has no refrigerating demand and the freezing compartment 20 has a refrigerating demand, it is necessary to control the stopping of the blower fan 30 to prevent cool air from entering the refrigerating compartment 10. When the fan 30 stops working, if only the first evaporator 40 or the second evaporator 50 is controlled independently to perform cooling, the cooling effect in the freezing chamber 20 is poor, and the cooling is uneven, so that the embodiment of the application can cool the freezing chamber 20 by controlling the first evaporator 40 and the second evaporator 50 to perform cooling simultaneously to form a cooling air circulation, and the cooling speed of the freezing chamber 20 can be accelerated by the cooling air circulation, thereby reducing the energy consumption of the refrigerator 100.

Wherein, when controlling the first evaporator 40 and the second evaporator 50 to simultaneously cool, it may be to control the first evaporator 40 to cool at the first power; the second evaporator 50 is controlled to cool at a second power, wherein the first power is less than the second power. That is, since it is necessary to circulate the cool air when the freezing chamber 20 is cooled alone, the second evaporator 50 is mainly used when the freezing chamber 20 is cooled alone, and thus the energy consumption can be reduced. The specific values of the first power and the second power are set according to practical situations, and are not particularly limited herein.

In the cooling process, if the current temperature of the freezing chamber 20 reaches the shutdown temperature, the first evaporator 40 and the second evaporator 50 are controlled to stop operating.

With continued reference to fig. 7, fig. 7 is a schematic flow chart of the control method shown in fig. 4, in which both the freezing chamber and the refrigerating chamber have refrigeration requirements. When the refrigerating requirements of the refrigerating chamber and the freezing chamber are obtained, the specific control method flow is as follows:

401. when the refrigerating chamber and the freezing chamber have refrigeration requirements, the first evaporator and the fan are controlled to be started to work, and the fan is controlled to supply air to the refrigerating chamber through the air duct so as to control the temperature of the refrigerating chamber.

When both the refrigerating chamber 10 and the freezing chamber 20 have refrigeration requirements, the first evaporator 40 and the fan 30 can be controlled to be started to operate, and the fan 30 is controlled to supply air to the refrigerating chamber 10 through the air duct 60 so as to control the temperature of the refrigerating chamber 10.

402. After the fan works for a period of time, the current temperature of the refrigerating chamber is obtained, if the current temperature of the refrigerating chamber reaches the shutdown temperature, the fan is controlled to stop working, and the second evaporator is controlled to start working.

After the first evaporator 40 and the fan 30 are operated for a period of time, the current temperature of the refrigerating chamber 10 is obtained through the temperature sensor, the current temperature of the refrigerating chamber 10 is compared with the shutdown temperature of the refrigerating chamber 10, if the current temperature of the refrigerating chamber 10 reaches the shutdown temperature, the refrigerating chamber 10 is indicated to not need to be refrigerated, the fan 30 is controlled to stop working, and the second evaporator 50 is controlled to be started to work. If the current temperature of the refrigerating compartment 10 does not reach the shutdown temperature, which means that the refrigerating compartment 10 needs to continue to be refrigerated, the fan 30 and the first evaporator 40 are controlled to continue to operate.

403. After the fan stops working for a period of time, the current temperature of the freezing chamber is obtained, and if the current temperature of the freezing chamber reaches the shutdown temperature, the first evaporator and the second evaporator are controlled to stop working.

When the current temperature of the refrigerating compartment 10 reaches the shutdown temperature and the blower 30 stops operating for a while, the current temperature of the freezing compartment 20 is obtained, the current temperature of the freezing compartment 20 is compared with the shutdown temperature of the freezing compartment 20, and if the current temperature of the freezing compartment 20 reaches the shutdown temperature, it is indicated that the freezing compartment 20 does not need to be cooled either, so that the first evaporator 40 and the second evaporator 50 are controlled to stop operating.
