Abstract
The invention provides an air curtain type freezer. The position, 1-3 cm higher than a freezer door, of one side of the outer wall of a slide way of the pushing-and-pulling type freezer door is provided with an air outlet parallel to the freezer door, and an air suction port is formed in the other side in the same direction. When the freezer door is opened, a transverse air curtain generated on an opening can prevent outside water vapor from entering the freezer, and therefore the defrosting phenomenon can be reduced.
Description
Art
The present invention relates to a kind of wind-curtain type refrigerator-freezer, when cabinet door is opened, the horizontal air curtain that opening part produces can hinder external moisture to enter refrigerator-freezer, thus reducing refrigerator-freezer inwall frosting.
Background technology
At present, known refrigerator-freezer structure is made up of cabinet, refrigeration system, temperature control equipment three part. In the process used, refrigerator-freezer cabinet door needs through normally open, and external water branch enters inside cabinet with air, so, frosting, prolongation over time will be formed at refrigerator-freezer inwall, the thickness of frosting can be continuously increased, thus affecting the refrigerating efficiency of refrigerator-freezer, increases the energy consumption of refrigerator-freezer. Along with the development of fresh based article industry, refrigerator-freezer manufacturing enterprise, market, family use more and more extensive, the problem that effectively solves refrigerator-freezer frosting, for extending refrigerator-freezer service life, to reduce energy resource consumption significant.
Summary of the invention
In order to overcome existing refrigerator-freezer easily to produce the deficiency of frosting, the present invention provides a kind of wind-curtain type refrigerator-freezer, this refrigerator-freezer can pass through the entrance of external moisture during the effect effectively prevention refrigerator-freezer cabinet door unlatching of air curtain, thus effectively reducing the refrigerator-freezer inwall frosting degree because regular unlatching causes.
The technical solution adopted for the present invention to solve the technical problems is: in plug-type refrigerator-freezer pocket door slide outer wall side higher than 1-3 centimetre of position of cabinet door, be mounted parallel to the air outlet of cabinet door, in the equidirectional installation inlet scoop of opposite side. Stable air curtain is formed under the air outlet combined effect with inlet scoop. Air-out and inlet scoop are set to 4-6, and each air port width is set to 10-30 centimetre. Air switch is arranged on inside freezer door slideway, and when freezer door closes, switch is depressed, and now this switch correspondence blower fan cuts out, and then opens time contrary. The switch in each air port is arranged at the position in this air port and cabinet wall side distalmost end outdoors, and only when cabinet door fully slides out this position, this air port is just opened. So, the problem that when effectively prevent cabinet door closure state, air port is still run. One Fans is set, is simultaneously used for blowing and air draught, is arranged on bottom refrigerator-freezer. The operation of blower fan is subject to air port place on-off control and side all air switch corresponding power of fan of co-controlling. When a switch open, blower fan is with less Power operation, and when two switches start jointly, the operation power of blower fan increases, and when all switches are all opened, blower fan runs with peak power.
The invention has the beneficial effects as follows, after refrigerator-freezer cabinet door is opened, cabinet door place can produce the air curtain with certain flow rate, and this air curtain can stop external heat humid air to enter refrigerator-freezer, thus reducing refrigerator-freezer frosting degree.

Detailed description of the invention
In FIG, air outlet (1) is set to 6, and inlet scoop (2) are corresponding with air outlet quantity, and each air port width is set to 20 centimetres. The open and close of air outlet (1) and inlet scoop (2) are by the control of electronic valve switch (3), and electronic valve switch (3) realizes being turned on and off air outlet (1) and inlet scoop, relevant position (2) mainly through the open and close controlling electronic valve (5). Electronic valve switch (3) is arranged in slideway (4), and when freezer door closes, switch is depressed, and now this switch correspondence electronic valve (5) cuts out, and then opens time contrary. Each electronic valve switch (3) is positioned at the position in its controlled air port and cabinet wall side distalmost end outdoors, and only when plug-type cabinet door (6) fully slides out this position, this electronic valve (5) is just opened. Blower fan (7) is positioned at the bottom of refrigerator-freezer, being connected respectively through 6 air outlets (1) with refrigerator-freezer of a main pipeline (8) and 6 blower fan subtubes (9) and 6 inlet scoops (2), electronic valve (5) lays respectively at each subtube (9). The power of blower fan (7) is subject to electronic valve on-off control, power is divided into 3 grades, when only one of which electronic valve switch (3) is opened, 1 grade of energetic start up of blower fan, now blower fan is with less power motion, only meet the running in an air port, along with the increase opening electronic valve switch (3) number, blower fan (7) power improves constantly, due to Bidirectional pulling sliding door position limitation, only having at most 3 electronic valves switch (3) to be simultaneously open, therefore, 3 grades of power of fan arrange the running that can meet this refrigerator-freezer.
In the embodiment depicted in figure 2, air outlet (1) is set to 4, and inlet scoop (2) are corresponding with air outlet quantity, and each air port width is set to 30 centimetres. The open and close of air outlet (1) and inlet scoop (2) are by the control of electronic valve switch (3), and electronic valve switch (3) realizes being turned on and off air outlet (1) and inlet scoop, relevant position (2) mainly through the open and close controlling electronic valve (5). Electronic valve switch (3) is arranged in slideway (4), and when freezer door closes, switch is depressed, and now this switch correspondence electronic valve (5) cuts out, and then opens time contrary. Each electronic valve switch (3) is positioned at the position in its controlled air port and cabinet wall side distalmost end outdoors, and only when plug-type cabinet door (6) fully slides out this position, this electronic valve (5) is just opened. Blower fan (7) is positioned at the bottom of refrigerator-freezer, being connected respectively through 6 air outlets (1) with refrigerator-freezer of a main pipeline (8) and 6 blower fan subtubes (9) and 6 inlet scoops (2), electronic valve (5) lays respectively at each subtube (9). The power of blower fan (7) is subject to electronic valve on-off control, power is divided into 2 grades, when only one of which electronic valve switch (3) is opened, 1 grade of energetic start up of blower fan, now blower fan is with less power motion, only meet the running in an air port, along with the increase opening electronic valve switch (3) number, blower fan (7) power improves constantly, due to Bidirectional pulling sliding door position limitation, only having at most 3 electronic valves switch (3) to be simultaneously open, therefore, 2 grades of power of fan arrange the running that can meet this refrigerator-freezer.
