Abstract
The utility model provides a refrigerator cold air circulation structure and a refrigerator. The refrigerator cold air circulation structure can solve the problems that fresh-keeping basins in an upper structure in the prior art have relatively bad refrigeration effects. The refrigerator cold air circulation structure comprises an upper structure and a lower structure divided by a separator plate. A support frame is equipped inside the upper structure. The support frame comprises a support frame main body, a support frame front side wall, and a support frame rear side wall. The support frame is supported on a large opening on the top of the refrigerator body through the front side wall and the rear side wall. A plurality of fresh-keeping basins are equipped on the support frame main body. The refrigerator body rear side between the support frame and the separator plate is provided with a fan. A plurality of ventilating openings are equipped on the front side wall and the rear side wall of the support frame. A gap is equipped between the front of the large opening on the top of the refrigerator and the front side wall of the support frame. The refrigerator cold air circulation structure provided in the utility model makes the cold air inside the upper structure involved in the cold air circulation under the effects of the fan and minimizes the difference between the temperature of the cold air in the fresh-keeping basins in the upper parts and that of the cold air in the parts below the fresh-keeping basins and the inner side of the refrigerator body. Excellent refrigeration effects are then achieved.
Description
Technical field
The utility model relates to household electrical appliance technical field, is specifically related to a kind of refrigerator cold air circulating structure and refrigerator.
Background technology
Commercial refrigerator also is fresh-keeping workbench, can be divided into two kinds of direct-cooled type and Wind-cooling types according to the difference of refrigerating mode thereof.A kind of salad workbench that cries of the commercial refrigerator of Wind-cooling type; Primary structure is to comprise double-layer structure up and down; Separate with demarcation strip the centre; Superstructure is to store classifiedly various seasoning matter foods and fasten to keep temperature with cover with many fresh-keeping basins, and understructure is used for depositing the food than single kind, and through the blower fan of back cold air is circulated.Now general cold air circulating structure is that cold air that blower fan blows out just sees through demarcation strip and is blown in the understructure below the fresh-keeping basin and circulates; And blow less than in the superstructure; The temperature that the air of the superstructure of fresh-keeping basin can only reduce the top air through the heat transmission of cold air reaches cool effect; So often cause the inequality of two parts cold air temperature up and down, the refrigeration of top Freshness keeping disc is relatively poor.Given this plant situation, urgently will solve the circulation of air problem of superstructure.
Summary of the invention
The utility model provides a kind of refrigerator cold air circulating structure and refrigerator, and it can solve the relatively poor problem of fresh-keeping basin refrigeration in the superstructure that prior art exists.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is,
A kind of refrigerator cold air circulating structure; Comprise by demarcation strip double-layer structure up and down at interval, bracing frame is set in the superstructure, comprise the bracing frame main body; Bracing frame front side wall and bracing frame rear wall; Support frame as described above is provided with some fresh-keeping basins through the big opening part of its forward and backward side wall support at the cabinet top on the support frame as described above main body, the cabinet rear side between bracing frame and the demarcation strip is provided with blower fan; The forward and backward sidewall of support frame as described above is provided with some ventilating openings, between the big open front at said cabinet top and the support frame as described above front side wall slit is set.
The utility model is through offering ventilating opening on the forward and backward sidewall of bracing frame; And between the big open front at cabinet top and bracing frame front side wall, the slit is set; Like this, the cold air that blower fan blows out arrives fresh-keeping basin upper space through the ventilating opening above the bracing frame rear wall, is recycled to the bracing frame front side wall then; See through the ventilating opening above the front side wall; Circulate downwards through the big open front at cabinet top and the slit between the bracing frame front side wall again, see through demarcation strip again and arrive understructure and circulation backward, thereby realize the smooth and easy circulation of fresh-keeping basin top air.The superstructure air is smooth and easy to have circulated, and makes the cold air of superstructure under the power of blower fan, also participate in the circulation of cold air, and it is minimum that cold air temperature and the cold air temperature temperature difference in fresh-keeping basin below and the cabinet of top fresh-keeping basin are dropped to, and reaches good refrigeration.
Further, said ventilating opening is the venetian blind type structure, and said ventilating opening is a punching hole, all is ecto-entad punching presses on the forward and backward sidewall, makes the oblique fresh-keeping basin direction of opening of ventilating opening.
Further, said gap width is 5-10mm.To guarantee the smooth and easy circulation of cold air, bracing frame also can well be supported by the cabinet top simultaneously.
A kind of refrigerator; Its cold air circulating structure comprises by demarcation strip double-layer structure up and down at interval, and bracing frame is set in the superstructure, comprises the bracing frame main body; Bracing frame front side wall and bracing frame rear wall; Support frame as described above is provided with some fresh-keeping basins through the big opening part of its forward and backward side wall support at the cabinet top on the support frame as described above main body, the cabinet rear side between bracing frame and the demarcation strip is provided with blower fan; The forward and backward sidewall of support frame as described above is provided with some ventilating openings, between the big open front at said cabinet top and the support frame as described above front side wall slit is set.
Further, said ventilating opening is the venetian blind type structure.
Further, said gap width is 5-10mm.
The front end size of the big opening of the utility model through having strengthened the cabinet top; Bracing frame front side wall and cabinet top no longer tightly is close together but the slit of certain distance has been arranged; And on front side wall that supports fresh-keeping basin and rear wall, make the ventilating opening of blind window shape, the cold air that the rear blower fan is blown can circulate downwards through ventilating opening.
The utility model compared with prior art has the following advantages and good effect:
This new technique has solved fresh-keeping basin top air and can not circulate and can only lean on air heat to transmit temperature reduction way; Not only energy-conservation but also can be rapidly fresh-keeping basin top temperature be reduced, and in use effectively guarantee the temperature and below temperature spread minimum of fresh-keeping basin top.
This new technique has improved the structure of cabinet circulating cold air mode; Cold air above making also participates in the circulation of cold air under the power of blower fan; It is minimum that cold air temperature and fresh-keeping basin below and the cold air temperature temperature difference in the cabinet of top fresh-keeping basin are dropped to, and reaches good refrigeration.
