Problems solved by technology

In addition, in order to respond to market demands such as a larger storage capacity and a variety of forms, it is necessary to increase the size and variety of heat-insulating boxes, and this will lead to an increase in the size of the above-mentioned reinforcing member and a problem caused by an increase in the number of parts. The resulting increase in material and processing costs, investment costs for molding dies, increase in storage places, etc.

Embodiment approach 1

[0027] figure 1 It is a perspective view showing the outline of the appearance of the heat insulation box of the refrigerator according to Embodiment 1 of the present invention viewed from the front upper right, figure 2 is roughly figure 1 The exploded perspective view of the structure of the bottom surface part of the thermal insulation box shown, image 3 yes means figure 2 An enlarged perspective view of the assembly of the front reinforcement member and the front set leg shown, Figure 4 Looking up from the lower part of the rear rear side figure 1 The main part perspective view of the heat insulation box shown. In the figure, the heat insulation box (excluding the door) 10 constituting the main body of the refrigerator is filled with the heat insulation material 5 in the gap formed by the outer box and the inner box 4 (described later). Figure 5 The above-mentioned inner box 4 constitutes the inner wall, and the above-mentioned outer box is formed by a U-shaped o...

Embodiment approach 2

[0052] Figure 10 It is an exploded perspective view schematically showing the bottom surface member structure in the heat insulation box of the refrigerator concerning Embodiment 2 of this invention. In the figure, the rear reinforcing member 7A is formed only by a portion linearly extending in the front-rear direction, and the rear reinforcing member 7 that rises upward in an L-shaped appearance on the rear end side like the rear reinforcing member 7 of Embodiment 1 is omitted. part. The second embodiment is suitable for accommodating a small and light refrigerator with a capacity of less than 300 liters, for example, when the weight of the refrigerator is small and the load applied to the bottom of the refrigerator due to impacts such as dropping during transportation is small. , since there is no need to pass figure 2 The raised part of the rear side reinforcing member 7 as shown reinforces the rear part of the heat-insulating box of the machine room. Figure 10 As sho...

Embodiment approach 3

[0057] Embodiment 3 is in figure 2 In the exploded perspective view of the shown heat insulation box bottom surface member structure, the front side reinforcement member 6 and the rear side reinforcement member 7 are formed in thickness different from each other as needed. For example, when the front side reinforcing member 6 and the rear side reinforcing member 7 are shared among models with different storage capacities, the rear side is reinforced in order to withstand the load applied to the bottom surface of the refrigerator of a model with a large capacity. The member 7 is thicker than the front reinforcement member 6, and ensures the rigidity of the mechanical component storage space on the back side of the bottom surface. At this time, if the thickness of the steel plate differs by, for example, about 0.2 mm in the press working, the required dimensional accuracy can be ensured as a member forming the heat insulating box even if it is formed by the same press die.

Abstract

Provided is a refrigerator capable of securing the necessary strength and assembly workability while reducing the number of parts and the amount of materials used, even in cases of increased capacity and wide variation. The refrigerator is provided with a base plate member 3 forming a bottom outer surface of a heat insulating casing 10 and reinforcing members provided forming a pair extending, respectively, in a front-rear direction to a left edge part and a right edge part in a lower surface part of the base plate member as seen from a front side, wherein the reinforcing members are set so as to comprise a front side reinforcing member 6 provided to a front part side of the base plate member and fixed to the base plate member; and a rear side reinforcing member 7 arranged in a rear part separated with respect to the front side reinforcing member, and fixed to the base plate member.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a refrigerator with an improved bottom structure of a heat insulation box. Background technique [0002] The heat insulation box of the refrigerator needs to be able to withstand the total weight of the refrigerator itself and the load generated during transportation. The bottom surface of the heat insulation box is provided with a reinforcing member such as a pressed steel plate. In addition, in order to respond to market demands such as a larger storage capacity and a variety of forms, it is necessary to increase the size and variety of heat-insulating boxes, and this will lead to an increase in the size of the above-mentioned reinforcing member and a problem caused by an increase in the number of parts. The resulting increase in material and processing costs, investment costs for molding dies, and increase in storage locations. On the other hand, the heat insulation box structure of the refr...
