The utility model relates to a control device capable of controlling an air door heater according to humidity. The control device comprises an air door heater (1), a humidity sensor (2) and a controller (3), which are arranged on an air door, wherein the humidity sensor (2) is used for detecting the humidity of the air door and converting a detection result into an electric signal to be output to the controller (3), and the air door controller (1) is controlled to work through an output signal of the controller (3). According to the utility model, a control process comprises the following steps of: the humidity sensor (2) is used for detecting the humidity of the air door and converting a detection result into an electric signal to be output to the controller (3), and the heating time of the air door controller (1) is controlled through the output signal of the controller (3), wherein the heating time and the humidity are directly proportional. The utility model considers the actual icing condition of the air door, through mastering the real-time humidity condition of the air door, the air door heater is effectively controlled to work, the energy is saved, and the control device is low-carbon and environmental-friendly.
Description
Technical field
The utility model belongs to the technical field of refrigerator, particularly a kind of control device according to humidity control air door heater.
Background technology
The circulation of wind cooling refrigerator single system is to rely on freezing evaporimeter and fan that low-temperature receiver is provided, and refrigerating chamber directly freezes, and simultaneously through the air door switch time of control refrigerating chamber and refrigerating chamber center-aisle, realizes the purpose of refrigerating chamber refrigeration.Because the temperature difference huge (about 20 degree) causes air door to be easy to freeze, thereby causes air door to freeze cisco unity malfunction between refrigerating chamber and the refrigerating chamber.Eliminate icing phenomenon so need to increase heater assembly, guarantee the air door regular event.When general refrigerator is controlled the air door heater, all be to adopt the method for often opening to handle, and do not consider the icing situation of reality at air door place to have increased unnecessary energy consumption.
The utility model content
The problem that the utility model will solve is to the deficiency of prior art a kind of control device of controlling the air door heater in real time, efficiently according to humidity to be provided.The utility model control device is easy, energy efficient, with low cost.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of control device according to humidity control air door heater is provided; Comprise the air door heater, humidity sensor and the controller that are arranged on the air door; Said humidity sensor detects air door humidity and testing result is converted into the signal of telecommunication exports to controller, the work of controller output signal control air door heater.
Said humidity sensor is located at the surface of air door.Be convenient to better provide in real time the humidity situation at air door place.
Said air door heater is by chip microcontroller, and equipment is simple and reliable.
The utility model according to the control procedure of the control device of humidity control air door heater is: said humidity sensor detects air door humidity and testing result is converted into the signal of telecommunication exports to controller; The heat time heating time of controller output signal control air door heater, said heat time heating time and humidity are proportional.Through control, control the work of air door heater real-time and efficiently to the real-time humidity situation in air door place.
In the above-mentioned control procedure, the air door heater work period is 100s, and it comprises following working method:

The control procedure of the utility model is: humidity sensor 2 detects air door humidity and testing result is converted into the signal of telecommunication exports to controller 3, and the heat time heating time of controller 3 output signal controlling air door heaters 1, said heat time heating time and humidity are proportional.
1 work period of air door heater is 100s, concrete comprises following working method:
A, humidity are 0 o'clock, and the air door heater cuts out always;
B, humidity are 100%, and the air door heater heats always;
C, humidity are between 0 and 100%, and the heat time heating time and the humidity of air door heater are proportional.
The utility model is controlled the work of air door heater, energy savings, low-carbon environment-friendly real-time and efficiently through the control to the real-time humidity situation in air door place; Solved well that refrigerator in the prior art adopts the method for the heater of often blowing in and the problem of wasting energy consumption.
Above embodiment only is used to explain the technical scheme of the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to preferred embodiment; The those of ordinary skill in affiliated field is to be understood that; Still can make amendment and perhaps the part technical characterictic is equal to replacement the specific embodiment of the utility model; And not breaking away from the spirit of the utility model technical scheme, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
