Problems solved by technology

When the door of the refrigeration appliance is opened and the air curtain is used to prevent cold air from leaking out, because the external environmental conditions are constantly changing, for example, there is a big difference between the temperature and air pressure in the morning and the temperature and air pressure at noon. Power air curtain, when impacted by different external environments, the ability to protect the internal cold air is limited

Embodiment 1

[0034] Please refer to, a refrigeration appliance with an air curtain is designed. The refrigeration appliance is composed of a box body 1, a door body 2, an insulating foam layer, a refrigeration system, an air curtain system, and a control system 6. The foam layer divides the box body into at least one compartment, and each compartment corresponds to a door body 2 to form an independent low-temperature food storage space.

[0035] The air curtain machine 4 is made up of blower fan, shell, air inlet and air outlet, is installed on the side of independent space box body liner, and air curtain forms " door curtain " at the liner mouth.

[0036] The box refrigeration system is composed of conventional refrigeration components such as compressors, evaporators, capillary tubes, condensers, and filters.

[0037] The above-mentioned electronic devices are connected with the control system 6 .

[0038] The fan of the air curtain machine 4 is a centrifugal or axial flow, and is gener...

Embodiment 2

[0046]Please refer to, the refrigerating appliance consists of a sealed open-cavity box 1 composed of an insulating foam layer and an openable door 2 to form a closed refrigerating appliance low-temperature compartment 3. The refrigeration system keeps the refrigerating appliance low-temperature compartment 3 at a low temperature for use in Store food, etc. The air curtain machine 4 is suspended on the top of the box body 1 near the door body 2 . The door body 2 is also provided with a proximity door switch 5. When the door body 2 is opened, the proximity door switch 5 is in an off state, and when the door body 2 is closed, the proximity door switch 5 is closed. Electric devices such as the air curtain machine 4 and the proximity door switch 5 are connected with the control system 6 . When it is judged that the door body 2 is opened, the control system 6 immediately sends an instruction to make the door 4 start working.

[0047] Air curtain machine 4 is made up of centrifuga...

Abstract

The invention discloses a refrigerating appliance with an air curtain and a control method of the refrigerating appliance, and relates to the technical field of refrigeration. In the refrigerating appliance, an air curtain system comprises an air curtain machine, the air curtain machine comprises a centrifugal draught fan and a draught fan shell, and the air curtain machine is arranged on one sideof an independent space box inner container; an outside temperature sensing device and an outside air pressure sensing device are embedded in an outer panel of a door body; and an inside air pressuresensing device is embedded in a low-temperature chamber of the refrigerating appliance in a box. The air curtain machine is arranged in the refrigerating appliance, the outside temperature sensing device and the outside air pressure sensing device for sensing monitoring of the outside environment conditions and the inside air pressure sensing device for sensing monitoring of the interior of the refrigerating appliance are arranged, accordingly, the air curtain machine is correspondingly driven to conduct corresponding power adjustment according to the difference of the corresponding outside conditions and the refrigerating appliance interior condition, and for different outside environment impacts, the interior cold air protection degree is improved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a refrigeration appliance with an air curtain and a control method thereof. Background technique [0002] The existing air curtain machine is to form an "invisible door curtain" by driving the strong airflow generated by the cross-flow or centrifugal wind wheel. Divide the indoor and outdoor into two independent temperature zones to create a comfortable indoor environment, maintain the effect of indoor air conditioning and purify indoor air, save electricity while allowing air to circulate, and can effectively isolate dust, smoke, odor, insects and microorganisms Wait. Prevent cold (warm) air from flowing out, which can save electricity and effectively prevent cold (warm) air from escaping. The indoor and outdoor are divided into two independent temperature zones. When the air conditioner is running for a long time, the auxiliary circulation can adjust the temp...
