Abstract
An air curtain device of an air-cooled refrigerator comprises a sensor, a control panel and air supply devices, wherein the sensor, the control panel and the air supply devices are fixedly mounted on a control box, and the control box is mounted inside a refrigerator chamber by the aid of a fixing mechanism arranged on a side plate. According to the air curtain device of the air-cooled refrigerator, an air guiding groove is formed in each of upper and lower ends of the top of the position, closes to a door, of the control box, and air inlets of the air guiding grooves are connected with air outlets of the air supply devices. The air curtain device has the beneficial effects as follows: the air curtain device is simple in structure, and a refrigerator body is not required to be correspondingly refitted, so that the production time is greatly shortened; the air curtain device is wide in applicability and can be conveniently and easily mounted on whether novel refrigerators or old refrigerators, and thus the refrigerators have an air curtain function. Compared with the prior art, the air curtain device has the advantages of simple structure, convenience in use, low production cost, capability of saving energy and environment-friendliness.
Description
Technical field
The present invention relates to technical field of refrigeration equipment, specifically a kind of wind cooling refrigerator wind curtain device.
Background technology
Between electric refrigerator, room generally comprises cold room and refrigerating chamber, its type of cooling is divided into direct-cooling type and air-cooled, wherein, direct-cooling type is to utilize the mode of refrigerator inside natural convection air to reduce an indoor temperature, air-cooled, by fan and air channel cold air is delivered to each between indoor, forced air convection reduces an indoor temperature.Respectively there are pluses and minuses in two kinds of refrigeration modes, is Given this known item, does not carry out repeating comparing at this.
For air-cooling electric refrigerator, after opening chamber door, have a large amount of cold air overflow from inside, not easily cold air preserves, and cause that power consumption increases, in order to solve this problem, generally arranging an air curtain generating on the top of cold room in prior art, cold wind vertically blows out from this air curtain generating, forms one cold air barrier to stop the excessive of cold air.If China Patent No. is the patent of invention of a a kind of wind cooling refrigerator wind curtain device by name disclosed in 200620047087, comprising: sensor, panel, air-supply arrangement, the input of panel linked by the outfan of sensor, and the power control terminal of air-supply arrangement linked by the outfan of panel.Further, described sensor can be door switch sensor, and panel is PCB panel, and air-supply arrangement includes blower fan, air channel, nozzle, and the one end in air channel is positioned at fan outlet, and the other end is provided with nozzle.Nozzle may be installed wind cooling refrigerator inner tip by near-door part, and air-out direction is downward；Certainly, as long as effective air curtain can be formed, adopt other forms, for instance be arranged on bottom or both sides it is also possible that.The rectangle being shaped as strip of described nozzle, same, as long as effective air curtain can be formed, adopt the nozzle of other shapes it is also possible that.When opening the door, door body touches the signal of door switch sensor feedback enabling to PCB panel, and PCB panel provides fan power after receiving feedback signal, and the air-flow provided after fan operation is sprayed by nozzle through air channel.The rectangle being shaped as strip of nozzle, thus the air-flow sprayed from top to bottom becomes tentiform.The airflow field that air curtain is formed can stop the intrusion of the outer hot-air of refrigerator, thus reducing the rise of the ice the temperature inside the box caused because hot-air invades and the skewness of temperature.When closing behind the door, door switch sensor feedback closes gate signal to PCB panel, and PCB panel cutout fan power, blower fan is out of service.
The refrigerator of this structure largely solves the rise of ice the temperature inside the box because hot-air intrusion causes and the skewness of temperature affects the fresh keeping time of food and the problem of the quality of storage, but find in actual applications, the refrigerator of this structure also exists problems with, one, adopt longer air channel that wind is delivered to nozzle due to blower fan and air channel is arranged on refrigerator cavity wall, need to change if air channel or blower fan damage, then need to empty in refrigerator and even remove refrigerator enclosing cover and can be replaced, maintenance maintenance is caused inconvenience part, they are two years old, this structure wind cooling refrigerator wind curtain device needs cabinet body structure is reequiped, it is not suitable for existing refrigerator structure, add the expenditure of user, be not suitable for being widely popularized.
Summary of the invention
The present invention is directed to the defect of above-mentioned existence, the technical scheme of technical problem to be solved and proposition is: provide a kind of simple in construction, produces easily, wind cooling refrigerator wind curtain device easy to maintenance.
The present invention realizes with the following methods: a kind of wind cooling refrigerator wind curtain device, including sensor, panel, air-supply arrangement, wherein said sensor and panel and air-supply arrangement are fixedly mounted on control box, and the fixed mechanism that control box is provided with by side plate is arranged in refrigerator chamber.
In above-mentioned wind cooling refrigerator wind curtain device, described control box respectively sets a wind guide tank by the upper and lower two ends, top of near-door part, and the air intake mouth of wind guide tank is connected with the air outlet of air-supply arrangement.
In above-mentioned wind cooling refrigerator wind curtain device, described control box afterbody bottom has air vent, and described air-supply arrangement is fixedly mounted on above air vent, and air vent is connected with the air inlet of air-supply arrangement.
In above-mentioned wind cooling refrigerator wind curtain device, described sensor is door switch sensor, and door switch sensor passes through wire and panel.
The beneficial effects of the present invention is: 1) safeguard easily, easy to maintenance, control on box owing to panel and air-supply arrangement are incorporated into one by the present invention, if needing repairing maintenance, only control box need to be taken off and just completing to overhaul replacing；2) simple in construction, it is not necessary to casing is reequiped accordingly, greatly reduces the production time；3) usability is wide, no matter is new-type or old-fashioned refrigerator, can install this wind cooling refrigerator wind curtain device and make refrigerator have air curtain function, and simple installation is easy.Compared with prior art, having simple in construction, easy to use, production cost is low, the advantage of energy-conserving and environment-protective.
