Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for supporting a tank, such as an inner tank of a dishwasher, and more specifically, to a support structure for supporting a tank by a frame arranged below the tank. be.

Conventionally, for example, dishwashers do not have a frame to support the inner tub from below, and therefore, generally, a frame-shaped base is formed by combining beams made of bent sheet metal, or a frame-shaped base is formed integrally. The structure consisted of a pedestal drawn and molded as a base, with pillars erected from each corner, and the inner tank was fixed through these pillars.
In this case, when fixing the support and the inner tank,
It is necessary to form a mounting hole that penetrates the inner tank wall, and water usually scatters inside the inner tank, which not only complicates the process to deal with water leaks, but also makes it difficult to assemble. This increased the number of man-hours and required a large amount of cost.

In addition, the struts that are fixed to the inner tank are screwed to a part of the inner tank wall, so if an excessive load is applied during a fall or during use, it may deform the inner tank or lead to water leakage. The mounting surface is prone to misalignment, so the walls that make up the inner tank needed to have considerable strength.

The present invention solves the above-mentioned conventional problems.

In this embodiment, a case will be described in which the present invention is applied to a dishwasher, but the present invention can be applied to support structures of tanks of other devices.

The main purpose of the present invention is to reduce the number of man-hours by simplifying the supporting structure of the tank, and to increase the strength of the main body structure by maintaining the entire bottom peripheral part, which is a stable part of the tank. without lowering
The purpose is to enable the wall thickness dimensions of the tank, supports and underframe to be set small.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral 1 denotes an inner tank of a dishwasher, etc., which corresponds to the tank in the present invention, and inside which dishes to be washed are set and stored in a basket. A cleaning liquid is usually discharged from a spray nozzle into the inner tank 1, and the dishes are washed. Note that the inside of the inner tank is not shown because it is well known in the art.
2 is located below the inner tub 1 and forms the base of the lower part of the main body of the dishwasher. It is an underframe made of resin or the like, and an upwardly projecting inner tank support part 3 is integrally formed at the rear part of the frame to support the bottom part 4 and peripheral part 5 of the inner tank 1 from below.

Reference numeral 6 denotes two columns fixed to the left and right flanges of the front opening of the inner tank 1 from the outside. It is fixed to part 8 with a pin screw.

Reference numeral 9 denotes holding fittings attached to two places on the left and right sides of the upper peripheral edge of the inner tank 1. The holding fittings 9 are made of sheet metal or the like, and claws 10 are formed on the sides of the holding fittings 9.
is engaged with the peripheral edge 11 of the upper surface of the inner tank 1. 12 is an exterior that covers the outer surface of the main body, and has upper and lower flange parts 13 and 14. The upper flange part 13 is engaged with the upper surface of the approximately L-shaped part 9A at the upper end of the holding fitting 9, and the lower flange part 14 is Lower surfaces 15 on both left and right sides of the underframe 2
Furthermore, there is a protrusion 16 on the lower surface 15.
A plurality of protrusions are provided, and these protrusions are inserted and locked into engagement holes 17 protruding from the lower flange 14 of the exterior 12. The front flange 18 of this sheath 12 engages with the vertical rib 19 of the column 6 and is screwed to the column 6.

The inner tank support part 3 of the underframe 2 includes a groove part 20 into which the peripheral edge part 5 of the bottom part 4 of the inner tank 1 is fitted, a rib 21 which supports the bottom part 4 of the inner tank 1 from below, and the peripheral edge part 5 from the outer periphery. It consists of a holding rib 22 for holding, and a part of the rear side part 5A and side part 5B of the peripheral edge part 5 of the inner tank 1 are each held by this inner tank support part 3.

Reference numeral 23 designates a piping relief section formed by recessing the rear part of the underframe 2, through which a drainage hose 24 for discharging the cleaning liquid used inside the main body to the outside of the machine, a pressure hose 25 for water supply, etc. are connected to the outside of the machine. An insertion hole 26 for piping is provided in the back surface 27 of the underframe 2. Even if these hoses 24 and 25 are bent to the left or right after coming out of the insertion hole 26 and installed with the back of the main body pressed against the wall of the room, they can still be connected through the space of the piping relief section 23 described above. can be connected to the section.

According to the above configuration, not only the side parts of the inner tank 1 are partially held by the support, but also the vicinity of the ridgeline, which is a strong and stable part of the box-shaped inner tank 1, is held, and the inner tank 1 The inner tank 1 is supported by the retaining ribs 22 so as to be supported from the side and rear surfaces of the main body, and the inner tank 1 is stably held even if impact force is applied to the main body from the outside, and abnormalities such as deformation, distortion, and hammering of the inner tank 1 occur. This is something I tried not to do. In addition, to connect the inner tank 1 and the underframe 2, it is only necessary to insert the inner tank peripheral part 5 into the groove part 20 which is the inner tank support part 3 of the underframe 2, and the front column 6 is attached to the lower end of the inner tank 1. Assembly is completed by simply screwing the support mounting seat part 8 to the mounting boss part 7 of the underframe 2, resulting in a significant reduction in man-hours.

In addition, the rear part of the underframe 2 is recessed and the piping relief part 2 is
3, the piping of the hoses 24 and 25 can be connected smoothly, and troubles such as inability to drain water due to bending of the hoses 24 and 25, which have conventionally been a problem when piping, can be prevented. That is, if the hoses 24 and 25 are suddenly pulled out to the left or right immediately after coming out of the main body, there is a problem that the hoses 24 and 25 will break at the bent part and the drain hose 24 will become clogged. This problem can be solved by gently bending the space within the portion 23.

As described above, according to the present invention, the holding strength of the tank can be greatly increased without increasing the thickness of the tank, the frame, the supports, etc., and the number of assembly steps can be reduced.
