Abstract

The utility model relates to an air channel of an air cooling refrigerator, which mainly solves a vortex phenomenon generated in air circulation, an air channel is arranged in an interlayer between an upper and a lower chamber of a refrigerator, and the rear end of the air channel is extended to an evaporator place which is provided with a fan used for transferring cold air to the inner part of a room; the place near the evaporator is provided with an air opening used for transferring air to the upper and the lower chamber of the refrigerator, the front end of the air channel is provided with an upper and a lower air return openings which can cause that the upper and the lower chamber of the refrigerator can be communicated with the inner air channel, and the upper and the lower air return openings can be used for the air return; the cold air can enter the upper and the lower refrigerator chambers through the air transferring opening, when the cold air enters the air channel, the cold air uniformly and smoothly flows through the spaces of the upper and the lower chamber and enters the air return openings, and the uniform and thorough refrigeration of the refrigerator chambers can be ensured.

Description

Air duct of refrigerator

Technical field

The utility model relates to the refrigerator technology, specifically is the air channel design about air-cooled refrigerator.

Background technology

At present in refrigeration industry, wind cooling refrigerator has the direct cooling refrigerator excellent function that is beyond one's reach because of it, and popular day by day.But in the manufacture process of wind cooling refrigerator, lack reasonability because its air channel is arranged, thereby have many defectives and deficiency inevitably, circulation has vortex phenomenon as wind, and insufficient, freezing, the temperature of refrigerating chamber of freeze is difficult to assurance etc.

Technology contents

The purpose of this utility model provides a kind of novel air duct, avoids the vortex phenomenon that is produced in the wind circulation thus.

For achieving the above object, the technical solution adopted in the utility model is: a kind of Air duct of refrigerator, be provided with an air channel in the interlayer between the upper and lower chamber of refrigerator, the rear end, air channel extends to the evaporimeter place, the evaporimeter place is provided with cold wind is sent into indoor fan, it is characterized in that: be provided with to the air port of refrigerator upper and lower chamber air-supply near evaporimeter position place, the front end in described air channel be provided with the air feed that the interior air channel of the upper and lower chamber of refrigerator and its is communicated with return into upper and lower chamber return air inlet.

By above-mentionedly give, the setting of return air, cold wind enters upper and lower refrigerator chamber by air outlet, cold wind evenly flows through glibly up and down and enters return air inlet behind the space, chamber when entering the air channel by return air inlet, produce at the indoor no significant eddy current of refrigerator at cold wind, thereby guaranteed all even abundant of the indoor refrigeration of refrigerator.

The specific embodiment

Referring to Fig. 1,2,4, Air duct of refrigerator disclosed in the utility model, be included in an air channel 31 that is provided with in the interlayer 30 between the upper and lower chamber of refrigerator, interlayer 30 is a froth bed in fact, 31 rear ends, air channel extend to evaporimeter 40 places, evaporimeter 40 places are provided with cold wind are sent into indoor fan 50, be provided with to the

air port

61,34 of the upper and lower chamber of

refrigerator

10,20 air-supplies near evaporimeter 40 positions, the front end in described air channel 31 be provided with the air feed that the interior air channel 31 of the upper and

lower chamber

10,20 of refrigerator and its is communicated with return into upper and lower chamber

return air inlet

32,33.

As shown in Figure 1, 2, air port, last chamber 61 is by being located at evaporimeter 40 places, the hollow hole that the case cover 60 on evaporimeter 40 and fan 50 tops is offered constitutes, the volume damper 70 that is used to control the air output size is positioned at the path 80 of fan 50 sides, the lower end of this path 80 is provided with the air outlet 34 that communicates with following chamber, and path 80 links to each other through the cold air passage of control valve 70 with evaporimeter 40 places.

Shown in Fig. 1,2,4, the described outgoing direction of going up air port, chamber 61 is positioned at top and front upper part, and following chamber air outlet 34 is positioned at the position, both sides on the back top of chamber down, and release handle 71 parts of described control valve 70 are emerging in the position, front side of case cover 60.

As shown in Figure 3, the described chamber return air inlet 32 of going up evenly is arranged on the plate face 34 at interval for a plurality of apertures, and simultaneously referring to Fig. 2, the aspect angle of plate face 34 and interlayer is between 30 °～60 °, following chamber return air inlet 33 is made of even the layout at interval of a plurality of apertures, as shown in Figure 5.

Core of the present utility model is to provide two circulation canals, is respectively to go up chamber circulation canal and following chamber circulation canal, and the utility model is described in further detail below in conjunction with the cyclic process of cold wind.

In conjunction with Fig. 1, cold wind is set out by evaporimeter 40 and is entered in the refrigerator chamber, top 10 by air port, last chamber 61 behind passing through fan 50, the cold wind flow direction is shown in the direction of arrow among Fig. 2, indoor carry out cold and hot exchange back by on chamber return air inlet 32 enter in the air channel 31, the temperature control in the last chamber 10 can realize adjusting by temperature sensor.

In conjunction with Fig. 4, the cold blast rate that enters down chamber 20 is the ventilation that controls to adjust valve 70 by release handle 71, at first cold wind is set out behind passing through fan 50 by evaporimeter 40 and cold wind is delivered to control valve 70, control valve 70 is sent into chamber under the refrigerator with an amount of cold wind through air channel path 80 and following chamber air outlet 34, the cold wind flow direction shown in the direction of arrow among Fig. 2,4, indoor carry out cold and hot exchange back by on chamber return air inlet 33 enter in the air channel 31.

The above-mentioned hot blast that enters air channel 31 is sent to evaporimeter 40 places and cools off, and waits for next cold cycling.
