Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings wind cooling refrigerator 1 according to the embodiment of the present invention is described.
As Figure 1-Figure 4, casing 100, refrigerating evaporator 200, freezing fan 300, alternating temperature ducting assembly 400, temperature-sensing probe 500 and controller (not shown) is comprised according to the wind cooling refrigerator 1 of the embodiment of the present invention.
Be provided with refrigerator room 111 in casing 100, room 113 (above-below direction is as shown in the arrow A in Fig. 1-Fig. 4) between freezing compartment 112 and the alternating temperature in the vertical direction between refrigerator room 111 and freezing compartment 112, be provided with the air-supply passage 120 and return air channel 130 that are communicated with room 113 between freezing compartment 112 and alternating temperature in casing 100.
Refrigerating evaporator 200 is located at the position of corresponding freezing compartment 112 in casing 100, for freezing to freezing compartment 112.Freezing fan 300 is located in freezing compartment 112, and for being led room 113 between alternating temperature by air-supply passage 120 by the cold wind in freezing compartment 112, and cold between alternating temperature in room 113 returns freezing compartment 112 by return air channel 130.
Alternating temperature ducting assembly 400 to be located between alternating temperature in room 113, there is the exhaust air flue be communicated with air-supply passage 120 and the return airway 420 be communicated with return air channel 130, the return air inlet that alternating temperature ducting assembly 400 is provided with temperature sensing mouth, the air outlet be communicated with described exhaust air flue and is communicated with return airway 420 in alternating temperature ducting assembly 400.Temperature-sensing probe 500 is located in alternating temperature ducting assembly 400, and temperature-sensing probe 500 exposes from described temperature sensing mouth, for detecting the temperature between alternating temperature in room 113.Described controller is connected with freezing fan 300 with temperature-sensing probe 500 respectively, and described controller controls the rotating speed of freezing fan 300 according to the temperature detection value of temperature-sensing probe 500.
According to the wind cooling refrigerator 1 of the embodiment of the present invention, by arranging freezing fan 300 and the air-supply passage 120 and the return air channel 130 that are communicated with room 113 between freezing compartment 112 and alternating temperature, freezing fan 300 can be utilized to import between alternating temperature in room 113 by the cold air in freezing compartment 112 by air-supply passage 120, to realize the refrigeration of room 113 between alternating temperature.
In addition, by arranging temperature-sensing probe 500 and described controller, temperature-sensing probe 500 can be utilized to detect temperature between alternating temperature in room 113, described controller is made to control the rotating speed of freezing fan 300 according to the temperature detection value of temperature-sensing probe 500, to control the flow velocity that freezing fan 300 imports cold wind in room 113 between alternating temperature, realize the adjustment to temperature in room between alternating temperature 113.Because wind cooling refrigerator 1 regulates temperature between alternating temperature in room 113 by means of only regulating the rotating speed of freezing fan 300, not easily to cause between alternating temperature because miscellaneous part damages can not freezing in room 113 or temperature too low, not only temperature is regulated more accurately and reliably, and do not need to increase other devices (such as air door), the cost of air door can be saved like this, thus improve the cost performance of wind cooling refrigerator 1.
Therefore, have according to the wind cooling refrigerator 1 of the embodiment of the present invention that temperature-changing chamber temperature control is reliable, low cost and other advantages.
Below with reference to the accompanying drawings wind cooling refrigerator 1 according to the specific embodiment of the invention is described.
