Through this scheme, the refrigerator can realize cooling fast and heating pending food under the effect of high voltage electrostatic field. The scheme can also enable the refrigerator to have cooling and heating functions at the same time. On the other hand, the refrigerator can achieve rapid cooling or freezing by communicating the chamber and cool air outside the chamber. In addition, a circulating air duct is formed in the cavity, and the acting force of the fan is utilized to accelerate the heat circulation in the cavity and accelerate the thawing process. Moreover, when the high-voltage power supply works, a large amount of negative ions and a small amount of ozone are generated between the electrode plates, so that the object to be treated in the cooling/heating unit 10 is sterilized and deodorized.

The refrigerator may also be an upper and lower double door refrigerator or other type of refrigerator cooling/heating unit.

The embodiment of the invention also discloses a refrigerator working method, which comprises the following steps:

in the heating mode, the air passage 600 for communicating the cold source 20 with the chamber 1002 for accommodating the object to be processed is closed, and the electrostatic generating device 200 is activated to apply an electrostatic field to the chamber 1002;

The above-described method steps are not limited by the order, i.e., the closing of the air passage and the starting of the static electricity generating device are not in order, and can be performed simultaneously or sequentially. The same is true for opening the air passage and activating the static electricity generating device.

According to the scheme, the air channel is closed in the heating mode by selecting different working modes, and the heating or thawing process is accelerated by utilizing a heat source; in the rapid cooling mode, circulation of cool air between the chamber and the outside of the chamber is achieved, thereby accelerating the cooling or freezing process.

In one embodiment, before activating the static electricity generating apparatus 200, it may further include determining whether the chamber door 101 is closed.

In one embodiment, the method may include, in the rapid cooling mode, the first fan 400 operating to input cold air from the cold source 20 into the chamber 1002.

In one embodiment, the method may include, in the rapid cooling mode, stopping the operation of the static electricity generating apparatus 200 when the temperature sensor detects that the temperature of the object to be processed is lower than a preset value. For example, when the food temperature is detected to be lower than-18 ℃, the cooling or freezing process is finished and the static electricity generating apparatus 200 stops operating.

In one embodiment, the method may include activating a second fan 400' to facilitate heat exchange within the chamber 1002 in a heating mode. For example, in the heating mode, the air inlet 601 and the air outlet 602 of the air passageway 600 are closed, and the second fan 400' is simultaneously activated to drive the hot air of the installation room 1001 to the chamber 1002, thereby accelerating the heating or thawing process of the object to be processed in the chamber 1002.

In one embodiment, the temperature of the chamber 1002 is higher than a preset value, and the second fan 400' stops operating. For example, when the chamber temperature is detected to be higher than 0 ℃, the fan stops working; otherwise, the fan continues to operate.

In one embodiment, the static electricity generating apparatus 200 stops working when the temperature of the object to be processed is higher than a predetermined value. For example, in the heating mode, when the temperature of the food is detected to be higher than 0 ℃, the static electricity generating device 200 stops operating.

Wherein, the controller 30 is used for controlling to close the air inlet 601 and the air outlet 602 in the heating mode, and controlling to activate the static electricity generating device 200 to apply the electrostatic field to the chamber 1002; the air inlet 601 and the air outlet 602 are controlled to be opened in the rapid cooling mode, so that the cold air is input from the cold source 20 to the chamber 1002, and the static electricity generating device 200 is activated to apply the electrostatic field to the chamber 1002.

In one embodiment, the controller 30 is also used to control activation of the second fan 400' to facilitate heat exchange between the chamber 1002 and a heat source 300 in the heating mode.

In one embodiment, the controller 30 is configured to control the second fan 400' to stop when the temperature of the chamber 1002 is detected to be higher than a preset value in the heating mode. For example, when the temperature of the chamber is detected to be higher than 0 ℃, the fan is controlled to stop working; otherwise, controlling the fan to continue working

In one embodiment, the controller 30 is configured to control the static electricity generating apparatus 200 to stop operating when the temperature of the object to be treated is detected to be higher than a predetermined value in the heating mode. For example, in the heating mode, when the temperature of the food is detected to be higher than 0 ℃, the static electricity generating device 200 is controlled to stop operating.

In one embodiment, in the rapid cooling mode, when the temperature of the object to be processed is lower than a predetermined value, the controller 30 is configured to control the static electricity generating apparatus 200 to stop operating. For example, when the temperature of the food is detected to be lower than a predetermined value, for example, -18 ℃, the cooling or freezing process is finished, and the static electricity generating device 200 is controlled to stop working.

The operation mode of the refrigerator 50' may be selected or set by a mechanical button, an on-screen button, or a mobile terminal device.

Referring to fig. 5, the following describes the operation flow of the embodiment of the present invention in detail by taking the refrigerator 50 as an example.

The refrigerator 50 includes the aforementioned cooling/heating unit 10, which includes two operation modes, i.e., a rapid cooling mode and a heating mode. The user may select the operation mode of the refrigerator 50 through a touch screen or buttons of the refrigerator 50 or through a mobile device such as a mobile phone.

During heating or thawing, first temperature sensor 500 monitors the temperature of chamber 1002, and when the temperature of chamber 1002 is higher than 0 ℃, it indicates that thawing has been completed, and controls second fan 400' to stop working; otherwise, second fan 400' continues to operate to promote circulation of air within chamber 1002 to speed up the heating or thawing process.

At the same time, the second temperature sensor 500' also monitors the temperature of the thawed food. When the temperature of the food is higher than 0 ℃, indicating that the thawing is completed, the static electricity generating device 200 is controlled to stop working and quit the heating mode.

When the refrigerator 50 enters the rapid cooling mode, it is judged whether the chamber door 101 of the cooling/heating unit 10 is closed; after closing, the air inlet and air outlet are opened (601, 602), and the static electricity generating apparatus 200 operates to start the freezing or cooling process. In one embodiment, the first fan 400 may be activated simultaneously to circulate cool air to accelerate the freezing or cooling process. In the rapid cooling process, when the temperature of the food is detected to be lower than-18 ℃, the freezing process is finished, the static electricity generating device 200 stops working, and the rapid cooling mode is exited.
