Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a configuration of an air passage for cooling in a refrigerator.

2. Description of the Related Art In recent years, as a configuration for cooling the inside of a refrigerator, an indirect cooling system that circulates cool air by using an evaporator and a fan for air blowing is often used because defrosting by a user is unnecessary.

An embodiment of the above-described conventional refrigerator cooling and air path configuration will be described below with reference to FIGS. 3 and 4 with reference to the drawings.

Reference numeral 1 denotes an under-counter type refrigerator used in a kitchen such as a restaurant, which has a plurality of refrigerator compartment doors 2a, 2b, and 2c each made of a heat insulating material at a front opening, and is provided with a horizontally long heat insulating box 2 And a machine room 7 for accommodating the compressor 4, the condenser fan 5, and the condenser 6 is formed on the left side of the main body. Numeral 8 is an insulating wall composed of an outer box 8a, an inner box 8b, and a foam insulating material 8c filled between the boxes 8a and 8b, and constitutes a refrigerator compartment 9 for cooling and freshening food. The refrigerator compartment 9 is provided with a shelf 10 on which foods are placed.

Reference numeral 12 denotes a heat insulating wall provided at an upper portion of the machine room 7, which is press-fitted into a side opening 13 of the heat insulating wall 8. And insulation wall
Numeral 12 constitutes a cooling chamber 14 for generating cool air. The cooling chamber 14 is provided with an evaporator 15, a drain pan 16 for receiving drain water dropped from the evaporator 15, and a cooling fan 17 for blowing cool air cooled by the evaporator 15. Reference numeral 18 denotes a partition wall for introducing a relatively warm cool air at the lower bottom of the refrigerator compartment 9 to prevent a short circuit with the air discharged from the cooling fan 17 and a drain pan.
The cooling fan 17 and the evaporator 15 guide the cool air circulated.

Reference numeral 19 denotes a louver for sending cool air generated by the evaporator 15 to the refrigerator compartment 9 via the cooling fan 17, and a wind direction adjusting rib 20 for rectifying the cool air discharged from the cooling fan 17.
The synthetic resin is integrally molded.

 21 is food.

The operation of the refrigerator configured as described above will be described below.

The louver attached to the partition wall 18 rectifies the cool air blown from the cooling fan 17 by the air direction adjusting ribs 20 and circulates the cool air uniformly to the refrigerator compartment 9.

However, in the configuration described above, when the food 21 is placed so that the cool air sent from the cooling chamber 14 is in close contact with the front of the louver provided on the partition wall 18, the air passage is formed. An uncooled state occurs due to the blockage, so a separate ventilation duct must be provided. However, when the ventilation duct is used, the ventilation flow is disturbed, and therefore, there is a problem that the cooling efficiency is deteriorated in the horizontally long refrigerator compartment 9 having a wide width.

The present invention has been made in view of the above problems, and provides a structure capable of improving cooling efficiency even when food is placed in close contact with a louver.

Means for Solving the Problems In order to solve the above problems, the refrigerator of the present invention has a configuration in which a plurality of bosses are formed in a convex shape on the louver 19 on the front surface of the louver wind direction adjusting rib. is there.

Effect of the Invention According to the present invention, with the above-described configuration, in the food placed in close contact with the convex boss on the front face of the louver, the cool air sent from the fan through the space for the louver for adjusting the wind direction of the louver and the boss is evenly diffused up, down, left and right. Therefore, the cooling efficiency can be improved.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1 and FIG. The same components as those in the related art are denoted by the same reference numerals, and detailed description is omitted.

Reference numeral 22 denotes a plurality of bosses formed in a convex shape on the surface 23 of the louver wind direction adjusting rib 20.

The operation of the refrigerator configured as described above will be described below.

Relatively warm cold air entering from the lower bottom portion of the partition wall 18 is guided to the partition wall 18, passes through the cooling chamber 14, is cooled by the evaporator 15, and is cooled by the cooling fan 17 to the surface of the wind direction adjusting rib 20.
A plurality of bosses 22 are discharged into the refrigerator compartment 9 via a louver 19 formed in a convex shape.

Even when the food 21 is placed in close contact with the front of the louver 19, the boss 22 formed in a convex shape allows the cool air to be evenly refrigerated due to the space between the front of the louver 19 and the food 21. The cooling efficiency is improved because it is diffused into the chamber 9.

Effect of the Invention As described above, the present invention provides a food product having a configuration in which a plurality of bosses are formed in a convex shape on the front surface of a synthetic resin louver with a wind direction adjusting rib attached to the surface of a refrigerator partition wall. Even when the air conditioner is installed in close contact with the louver surface, the cool air blown from the fan can be diffused more uniformly into the refrigerator compartment from the space of the boss, and the cooling efficiency can be improved.
