Air flow circulation device for food refrigeration display cabinet

Abstract

The invention relates to an air flow circulation device for a food refrigeration display cabinet and belongs to the technical field of domestic appliances. The food refrigeration display cabinet comprises a cabinet body, wherein the cabinet body is provided with a cabinet chamber, a cabinet door and a lamp box; a cabinet chamber roof plate is arranged at the top of the cabinet chamber; cabinet body foaming layers are arranged between a rear cabinet body plate and a rear cabinet chamber wall, between the lamp box and the cabinet chamber roof plate and between the left and right lateral plates of the cabinet body and the left and right outer walls of the cabinet chamber; the air flow circulation device comprises a fan and is characterized in that a fan accommodating chamber and an air flue cavity are sunken in the surface of the cabinet chamber roof plate and on one side, facing to the cabinet chamber, of the cabinet chamber roof plate; the fan is fixed in the fan accommodating chamber; a fan air outlet of the fan is corresponding to the air flue cavity. The suspension mode in the prior art is changed into the hidden mode, so that the occupation for the space of the cabinet chamber is avoided, the fan is prevented from being impacted by food and the viewing effect can be enhanced. Air flow discharged from the fan air outlet of the fan is concentrated, so that the fan efficiency is increased and the energy-saving effect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of household appliances, and specifically relates to an air circulation device of a food refrigerated display cabinet. Background technique [0002] In order to avoid the temperature difference in the cabinet cavity of the food refrigerated display cabinet (ie, the refrigerator compartment, the same below), for example, the temperature of the upper part of the cabinet cavity is higher than the temperature of the lower part, so it is necessary to install an air circulation device on the top of the cabinet cavity. The air in the cabinet cavity is in a circulating state to achieve the goal of uniform temperature in the cabinet cavity and prevent the food in the upper part of the cabinet cavity from deteriorating. [0003] The air circulation device of the food refrigerated display cabinet in the prior art is composed of Figure 4 As shown, on the top of the cabinet cavity 11 of the cabinet 1 and at a position correspon...

AI Technical Summary

Problems solved by technology

[0004] The air circulation device of the food refrigerated display cabinet with the above structure has the following technical problems in the actual use process: First, because the entire fan 2 is suspended, it occupies the limited space of the cabinet cavity 11 to a certain extent. Very valuable space; the second, there is the danger that the fan 2 is damaged by the impact of food, because in the process of placing food in the cabinet cavity 11, the fan 2 will be hit if carelessness; third, because the fan 2 is exposed It is installed in a vertical position, thus impairing the simplicity and visual effect of the cabinet cavity 11; Fourth, because the fan 2 is suspended, it is not conducive to the construction of an air duct, that is, it is impossible to form a diversion cavity, so that the air circulation efficiency of the fan 2 is low, which is not conducive to save energy
