Description

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

Conventionally, for example, in a dishwasher, there is no example in which a frame is provided to support an inner tub from below. The nine-frame frame molded from resin or the like used in washing machines is installed on the lower flange of the exterior, and screws are often used as the connection means. In addition, in a dishwasher, there is no connection between the inner tank and the underframe, which is the case with the above-mentioned method, and the peripheral edge of the inner tank is usually inserted into the upper flange of the exterior and fixed with several screws. has been done. Therefore, the inner tank is suspended inside the exterior, and its strength is weak.
To strengthen it, reinforcing plates were often added to connect it to the exterior.

Most of the underframes used in dishwashers, etc. are made of sheet metal.The frame is made of bent beam-like plates, and supports are erected from each corner, and the inner tank is fixed to the supports. The sheet metal frame and supports that support the tank are strong in terms of strength, but the parts that are attached to the inner tank are often screwed, so the mounting holes must be drilled through the inner tank wall. In addition, the inner tank wall itself must have the necessary strength to sustain the fall impact applied to the underframe and the load during use, which reduces not only assembly man-hours but also material costs. But it was getting expensive.

The present invention solves the above-mentioned conventional problems by supporting the tank not locally but globally.
This is intended to reduce assembly man-hours by simplifying the support structure of the inner tank, and also to prevent deformation, displacement, etc. of the fixed part of the inner tank due to vibrations and dropping impacts during product transportation.

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, which corresponds to the Japanese cypress in the present invention, in which tableware to be washed is stored set 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 a conventional well-known tank. 2
is an underframe integrally molded of resin or the like, which is located below the inner tank 1 and forms the base of the lower part of the main body of the dishwasher, and an inner tank support part 3 that protrudes upward is integrally formed at the rear of the frame. , supports the bottom part 4 of the inner tank 1 and its peripheral part 6 downwardly.

Reference numeral 6 denotes two columns fixed to the left and right 7 lunges of the front opening of the inner tank 1 from the outside.The lower ends are placed on the mounting bosses 7 at the front left and right corners of the underframe 2, and the columns 6 are supported from below. It is fixed to the mounting seat part 8 with tapping screws.

9 is attached to two places on the left and right sides of the upper surface of the inner tank 1.
It is engaged with the peripheral edge 11 of the upper surface. 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 abbreviated part 9m at the upper end of the holding fitting 9, and the lower 7 flange part The portion 14 is engaged with a lower surface 16 on both left and right sides of the underframe 2, and several protrusions 16 are formed on the lower surface 16, and these protrusions 16 are bored into the lower flange portion 14 of the outer device 2. It is inserted into and locked into the engagement hole 17 formed in the above-mentioned manner. The front 7 flange 18 of this outer device 2 is engaged with the vertical lip 19 of the column 6 and is screwed to the column 6.

Inner tank support part of underframe 2? is the peripheral edge 6 of the bottom surface 4 of the inner tank 1
It consists of a groove 2o into which the bottom surface 4 of the inner tank 1 is inserted, a rib 21 that supports the bottom surface 4 of the inner tank 1 from below, and a holding rib 22 that holds the peripheral edge 6 from the outer periphery. Part of the side portion 6B is held by the inner tank support portion 3 of each side.

Reference numeral 23 denotes a piping relief part formed by recessing the rear part of the underframe 2, and a drainage hose 24 for discharging cleaning liquid used in the main body to the outside of the machine, a pressure hose 26 for water supply, etc.
An insertion hole 26 for piping inside and outside the machine is inserted into the back part 2 of the underframe 2.
It is set at 7. These hoses 24.25 are inserted into the insertion holes 2
Even if the main body is bent to the left or right after coming out of the pipe 6 and installed with the back side of the main body pressed against the wall of the room, it can be connected to a predetermined connection part through the space of the piping relief part 23 described above.

According to the above configuration, not only the sides of the inner tank 1 are partially supported by the supports, but also the vicinity of the ridgeline, which is a strong and stable part of the box-shaped inner tank 1, is supported, and the inner tank 1 is The inner tank 1 is supported stably by the retaining ribs 22 that fit in from the side and rear surfaces, even if vibration or impact force is applied to the main body from the outside.
This is to prevent abnormalities such as deformation and distortion of the inner tank 1, dents, and loosening of the attachment parts.

In addition, to connect the inner tank 1 and the underframe 2, it is only necessary to insert the inner tank peripheral part 6 into the groove part 18, which is the inner tank support part 3 of the underframe 2, and the installation is then done on the bottom of the inner tank 1. The vertical relationship between the inner tank 1 and the underframe 2 is maintained with high precision by the ribs 21 that support the section 4 from below. The through hole shown in the figure and the lower end of the caulking are provided with a groove 20, and the installation is done so that there will be no variation in the later related dimensions. In addition, also in the left-right direction and the front-back direction, the inner peripheral wall of the peripheral edge of the inner tank 1 is connected to the rib 2.
1, so there is little variation in dimensions.

In addition, since the inner tank 1 and the underframe 2 are only connected by fitting and are not attached with screws, vibrations transmitted from the inner tank 1, such as those of a pump or motor, are buffered at this part. , it is possible to prevent the vibration of the main body and the noise caused by it from being transmitted to the underframe 2 and the exterior.

Also, when the main unit is exposed to high or low temperatures,
When the material of the inner tank 1 is metal and the material of the underframe 2 is resin, the dimensional change due to the difference in coefficient of thermal expansion is very large. Particularly, when the inner tank 1 and the underframe 2 are directly screwed together, the attachment may cause distortion of the parts and even cracks due to stress distortion. However, by fitting the peripheral portion 6 into the groove portion 2o, such distortions and the like are absorbed, resulting in extremely stable attachment.

As is clear from the above embodiments, the present invention provides an upwardly open groove on the outer periphery of the resin underframe, and in this groove,
By fitting the periphery of the bottom surface of the tank, deformation in the supporting portion of the Japanese cypress can be absorbed, and furthermore, there are effects such as no variation in the fitting diameter.
