Abstract
The invention relates to a wind screen device of a wind cooled refrigerator, which comprises a door opening and closing sensor, a PCB sensor, a PCB control board, a blower, a wind channel, and a nozzle. The output end of the door opening and closing sensor is connected with the input end of the PCB control board, the output end of the PCB control board is connected with the power supply control end of the blower, one end of the wind channel is positioned on the wind outlet of the blower while the other end of the wind channel is provided with the nozzle which is arranged on the top in the wind cooled refrigerator near the outer door with the upward wind blowing direction. When the refrigerator door is opened, the air flow field formed by the wind screen system can prevent the invasion of the outer hot air of the refrigerator; when the door is closed, the blower stops to run, thereby relieving the recovering temperature in the refrigerator and the uneven distribution of the temperature caused by the invasion of the hot air, prolonging the freshness keeping time of the foods and ensuring the quality of the storage.
Description
Technical field
The invention belongs to art of refrigeration units, relate to the technology that keeps temperature in the refrigerator.
Background technology
The user runs into the door opening times time many or that open the door long the time when using refrigerator, tend to cause in the refrigerator temperature sharply go up and Temperature Distribution irregular, the appearance of this situation can make that the fresh keeping time of storage food shortens in the refrigerator, the quality reduction.
Summary of the invention
The purpose of this invention is to provide a kind of wind cooling refrigerator wind curtain device, wish that can completely cut off heat after opening the door imports into, the air curtain apparatus of temperature equalization more meets user's demand in the maintenance refrigerator, addresses the above problem.
For achieving the above object, solution of the present invention is: a kind of wind cooling refrigerator wind curtain device comprises: sensor, and control panel, air-supply arrangement, the output of sensor is linked the input of control panel, and the output of control panel is linked the power control terminal of air-supply arrangement.
Further, described sensor can be a door switch sensor, and control panel is the PCB control panel, and air-supply arrangement comprises blower fan, the air channel, and nozzle, an end in air channel is positioned at fan outlet, and the other end is provided with nozzle.
Nozzle can be installed in the wind cooling refrigerator inner tip by near-door part, and air-out direction is downward; Certainly,, adopt other forms, for example be installed in bottom or both sides and also be fine as long as can form effective air curtain.
Described its shape of nozzle is rectangular rectangle, and is same, as long as can form effective air curtain, adopts the nozzle of other shapes also to be fine.
When opening the door, the signal that door body shake-up door switch sensor feedback is opened the door is given the PCB control panel, and the PCB control panel provides fan power after receiving feedback signal, and the air-flow that provides behind the fan operation is sprayed by nozzle through the air channel.Its shape of nozzle is rectangular rectangle, thereby the air-flow of ejection becomes tentiform from top to bottom.The airflow field that air curtain forms can stop the intrusion of the outer hot-air of refrigerator, thereby has reduced to invade the rise of temperature in the refrigerator that causes and the skewness of temperature because of hot-air.When closing behind the door, the door switch sensor feedback is closed gate signal to the PCB control panel, PCB panel cutout fan power, and blower fan is out of service.
The airflow field that is formed by air curtain system after the user opens the door can stop the intrusion of the outer hot-air of refrigerator, invade the rise of temperature in the refrigerator cause and the skewness of temperature thereby alleviated because of hot-air, thus prolonged food fresh keeping time, guaranteed the quality of storage.
Description of drawings
Fig. 1 is the front view of an embodiment of the present invention;
Fig. 2 is the present invention's right cutaway view embodiment illustrated in fig. 1.
The specific embodiment
Specifically see also and see Fig. 1,2, a kind of wind cooling refrigerator wind curtain device, wherein: door switch sensor 1, PCB control panel 2, blower fan 3, air channel 4, nozzle 5, shelf 6.The output of door switch sensor 1 is linked the input of PCB control panel 2, and the output of PCB control panel 2 is linked the power control terminal of blower fan 3, and an end in air channel 4 is positioned at blower fan 3 air outlets, and the other end is provided with nozzle 5.
Nozzle 5 is installed in the wind cooling refrigerator inner tip by near-door part, and air-out direction is downward.
When opening the door, a signal that body shake-up door switch sensor 1 feedback is opened the door is given PCB control panel 2, and PCB control panel 2 provides blower fan 3 power supplys after receiving feedback signal, and the air-flow that provides after blower fan 3 operations is sprayed by nozzle 5 through air channel 4.Nozzle 5 be shaped as rectangular rectangle, thereby the air-flow of ejection becomes tentiform from top to bottom.The airflow field that air curtain forms can stop the intrusion of the outer hot-air of refrigerator, thereby has reduced to invade the rise of temperature in the refrigerator that causes and the skewness of temperature because of hot-air.When closing behind the door, door switch sensor 1 feedback is closed gate signal to PCB control panel 2, and PCB control panel 2 cuts off blower fans 3 power supplys, and blower fan 3 is out of service.
The airflow field that is formed by air curtain system after the user opens the door can stop the intrusion of the outer hot-air of refrigerator, thereby has reduced to invade the rise of temperature in the refrigerator that causes and the skewness of temperature because of hot-air, thus the fresh keeping time and the quality that have prolonged food.
The above-mentioned description to embodiment is can understand and use the present invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the foregoing description, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
