Description

Air curtain type freezer
Technical Field
The invention relates to an air curtain type freezer, when a cabinet door is opened, a transverse air curtain generated at an opening can block external water vapor from entering the freezer, so that frosting on the inner wall of the freezer is reduced.
Background
At present, the well-known ice chest structure is composed of a chest body, a refrigerating system and a temperature control device. In the use process, refrigerator door needs often to be opened, and outside moisture can get into the internal portion of cabinet along with the air together, like this, will form at the refrigerator-freezer inner wall and frost, along with the extension of time, the thickness that frosts can constantly increase to influence the refrigeration efficiency of refrigerator-freezer, increase the energy consumption of refrigerator-freezer. Along with the development of the fresh product industry, the refrigerator is more and more widely used in production enterprises, markets and families, the problem of frosting of the refrigerator is effectively solved, and the refrigerator has important significance for prolonging the service life of the refrigerator and reducing energy consumption.
Disclosure of Invention
In order to overcome the defect that the conventional refrigerator is easy to frost, the invention provides the air curtain type refrigerator, which can effectively prevent external water vapor from entering when a door of the refrigerator is opened through the action of an air curtain, so that the frosting degree of the inner wall of the refrigerator caused by frequent opening is effectively reduced.
The technical scheme adopted by the invention for solving the technical problem is as follows: an air outlet parallel to the cabinet door is arranged at the position that one side of the outer wall of the sliding way of the sliding cabinet door is 1-3 cm higher than the cabinet door, an air suction opening is arranged at the other side in the same direction, and a stable air curtain is formed under the combined action of the air outlet and the air suction opening. The number of the air outlet and the number of the air suction openings are set to be 4-6, the width of each air opening is set to be 10-30 cm, the air opening switches are arranged inside the slideway of the refrigerator door, when the refrigerator door is closed, the switches are pressed down, the air openings corresponding to the switches are closed at the moment, and when the refrigerator door is opened, the switches of the air openings are all arranged at the positions of the air openings and the farthest end of the cabinet wall outside the cabinet door, and only when the cabinet door completely slides out of the positions, the air openings are opened, so that the problem that the air openings still operate when the cabinet door is closed is effectively solved. The refrigerator is provided with one fan, is used for blowing and sucking air and is arranged at the bottom of the refrigerator. The operation of the fan is controlled by the switch at the air inlet, and the corresponding fan power is controlled by all the air inlet switches at one side together.
The invention has the beneficial effects that after the door of the freezer is opened, the door of the freezer can generate the air curtain with certain flow velocity, and the air curtain can prevent external hot and humid air from entering the freezer, thereby reducing the frosting degree of the freezer.
Drawings
The invention is further illustrated with reference to the following figures and examples.
Fig. 1 is a configuration diagram of embodiment 1 of the present invention.
In the figure 1, 1 is an air outlet, 2 is an air suction opening, 3 is an electronic valve switch, 4 is a cabinet door slideway, 5 is an electronic valve, 6 is a push-pull cabinet door, 7 is a fan, 8 is a main fan pipeline, and 9 is a branch fan pipeline.
Fig. 2 is a configuration diagram of embodiment 2 of the present invention.
In fig. 2, 1 is an air outlet, 2 is an air suction opening, 3 is an electronic valve switch, 4 is a cabinet door slideway, 5 is an electronic valve, 6 is a push-pull cabinet door, 7 is a fan, 8 is a main fan pipeline, and 9 is a branch fan pipeline.
Detailed Description
In fig. 1, the number of the air outlets 1 is 6, the number of the air suction openings 2 corresponds to that of the air outlets, and the width of each air opening is 20 cm. The opening and closing of the air outlet 1 and the air suction opening 2 are controlled by the electronic valve switch 3, and the electronic valve switch 3 mainly controls the opening and closing of the electronic valve 5 to realize the opening or closing of the air outlet 1 and the air suction opening 2 at the corresponding position. The electronic valve switch 3 is arranged in the slide way 4, when the refrigerator door is closed, the switch is pressed, and the switch is closed corresponding to the electronic valve 5, and is opened when the refrigerator door is closed. Each electronic valve switch 3 is positioned at the position of the farthest end of the controlled air opening and one side of the outer wall of the cabinet door, and the electronic valve 5 is opened only when the push-pull cabinet door 6 completely slides out of the position. The fan 7 is located the bottom of refrigerator-freezer, divides pipeline 9 to link to each other with 6 air outlets 1 and 6 inlet scoop 2 of refrigerator-freezer through a trunk line 8 and 6 fans respectively, and the electronic valve 5 is located each branch pipeline 9 respectively. The power of fan 7 receives the electronic valve switch control, the power divide into 3 shelves altogether, when only one electronic valve switch 3 opens, 1 shelves power of fan starts, the fan moves with less power this moment, only satisfy the function in an wind gap, along with the increase of opening the electronic valve switch 3 number, 7 power of fan constantly improve, because two-way sliding door position limitation, only have 3 electronic valve switches 3 at most and opened by the while, therefore, 3 shelves fan power setting can satisfy the function of this refrigerator-freezer.
In the embodiment shown in fig. 2, 4 air outlets 1 are provided, the number of the air suction openings 2 corresponds to that of the air outlets, and the width of each air opening is set to be 30 cm. The opening and closing of the air outlet 1 and the air suction opening 2 are controlled by the electronic valve switch 3, and the electronic valve switch 3 mainly controls the opening and closing of the electronic valve 5 to realize the opening or closing of the air outlet 1 and the air suction opening 2 at the corresponding position. The electronic valve switch 3 is arranged in the slide way 4, when the refrigerator door is closed, the switch is pressed, and the switch is closed corresponding to the electronic valve 5, and is opened when the refrigerator door is closed. Each electronic valve switch 3 is located at the position of the farthest end of the air opening controlled by the electronic valve switch and one side of the outer wall of the cabinet door, and the electronic valve 5 is opened only when the push-pull cabinet door 6 completely slides out of the position. The fan 7 is arranged at the bottom of the freezer and is respectively connected with 6 air outlets 1 and 6 air suction openings 2 of the freezer through a main pipeline 8 and 6 fan branch pipelines 9, and the electronic valves 5 are respectively arranged at the branch pipelines 9. The power of fan 7 receives the electronic valve switch control, the power divide into 2 shelves altogether, when only one electronic valve switch 3 opens, 1 shelves power of fan starts, the fan moves with less power this moment, only satisfy the function in an wind gap, along with the increase of opening the electronic valve switch 3 number, 7 power of fan constantly improve, because two-way sliding door position limitation, only have 3 electronic valve switches 3 at most and opened by the while, therefore, 2 shelves fan power setting can satisfy the function of this refrigerator-freezer.
