Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a dishwasher.

(b) Conventional technology Previously, Publication No. 1986-8667 (A47L 15/42)
As shown in FIG. 14, the dishwasher shown in FIG.
It is composed of three members: a saucer-shaped bottom surface portion 55 that supports the lower surface of the frame portion 54, and a rear cover (not shown) that covers the rear surface of the frame portion 54.

Since various parts such as various pumps such as a cleaning tank and a circulation pump are installed inside the machine frame,
Before assembly of the washing machine, the machine frame cannot be stored as a complete product, and the three parts mentioned above are generally stored individually.

However, since the frame portion 54 has a U-shape, it is easily deformed by external forces from the side, and when deformed, there is a problem that assembly work is time-consuming.

It is also conceivable to separately install a reinforcing member in advance between both side surfaces 52 and 53 of the frame body part 54,
That would increase costs.

(c) Problems to be solved by the invention The invention prevents the deformation of the frame part of a dishwasher when parts are stored before assembly without increasing costs, thereby improving assembly work. This will enable you to do the same.

(d) Means for Solving Problems The dishwasher of the present invention has a frame portion formed by bending a rectangular sheet metal into a U-shape on the top and both sides of the machine frame. A cut portion is formed by cutting the rear corner portion across the top and side surfaces thereof, and a filter cover having a ventilation hole serving as a drying air path is installed in the cut portion between the two side surfaces. It is.

(e) Effect: That is, the filter cover also serves as a reinforcing member to prevent deformation of the frame body. Also, by cutting out the rear corner of the frame body, the sense of depth when viewed from the front is alleviated.

(f) Examples Embodiments of the present invention will be described based on the drawings.

Reference numeral 17 denotes a sheathed heater disposed at the bottom of the washing chamber 3, which heats the washing water and rinsing water and heats the washing water and the rinsing water during drying.
This increases the temperature inside the container, thereby promoting cleaning and drying.

Reference numeral 18 denotes a ventilation duct formed in the vertical direction on the rear surface of the cleaning chamber 3; The cleaning chamber 3
Drying air is introduced inside. Further, a joint pipe 22 is formed protruding outward near the outlet 19 of the air duct 18, and a water supply pipe 23 from a water supply source (not shown) is connected to the joint pipe 22, and water is supplied from the outlet 19. is also carried out. 24 is a water supply solenoid valve that controls water supply operation. Reference numeral 25 indicates an exhaust duct for discharging moisture in the cleaning chamber 3 along with dry air from the upper rear surface, 26 indicates a filter cover disposed at the rear corner of the machine frame 2, and 27 and 28 indicate the filter cover 26. an intake port of the fan device 21 and an exhaust duct 25 formed in the fan device 21;
29 is a drain pump that is disposed below the cleaning chamber 3 and is connected to a drain port (not shown) of the cleaning chamber 3; 30 is a drain pump that drains the cleaning liquid or rinsing liquid in the cleaning chamber 3 by the drain pump 29; This is a drain pipe for discharging water to the outside of the machine.
They are arranged in an inverted U-shape along the line a. The drain pipe 30 has a branch pipe 31 on the way from the drain pump 29 to the top of the drain pipe 30.
A terminal end 31a of the branch pipe 31 is connected to a second joint pipe 32 that is formed to protrude above the joint pipe 22 of the air duct 18. 33... are various operation switches and power switches arranged at the front lower part of the machine frame 2, and 34 are electrical components connected to each of these switches 33....

Here, as shown in FIGS. 6 to 9, the machine frame 2 includes a frame portion 35 which is bent into a U-shaped cross section to form an upper surface 2a and both side surfaces 2b and 2c; A saucer-shaped bottom portion 36 that supports the lower end of the frame portion 35 and a rear cover 3 that covers the rear opening of the frame portion 35
It consists of 7. Incidentally, the front part of the bottom part 36 constitutes an operation panel 38 at the lower front of the machine frame.

The frame portion 35, the bottom portion 36 and the rear cover 37
are stored separately for each part and are integrated into the machine frame 2 when the washing machine is assembled. However, in the frame part 35, there is a part at the rear corner extending diagonally across the top and side surfaces. By forming a cut portion 39 and screwing the filter cover 26 onto the cut portion 39 in advance, the filter cover 26 can be attached to the both side surfaces 2b,
It is constructed between 2c. That is, when handling the frame body part 35, it is easily deformed by applying an external force in the direction of the arrow in FIG. Deformation of the frame portion 35 is prevented without using a separate member. In addition, by cutting the rear upper part of the frame body part 35, the area of the upper surface of the machine frame 2 is apparently smaller, and the front (in the direction of the arrow in FIG. 6)
The sense of depth of the device body when viewed from above is alleviated. Furthermore, the intake and exhaust ports 27 and 28 of the filter cover 26 are also opened diagonally, so that even if something is placed on the top surface of the device, it will not be blocked by this.

Next, as shown in FIGS. 10 to 13, the cleaning chamber 3 includes a top plate 40, a side plate 41, and a bottom plate 42.
It is composed of three members. The top plate 40 is formed by bending each side edge of a rectangular sheet metal upward by 90 degrees to form a rising wall, and the side plate 41 is formed by bending a rectangular sheet metal into a U-shape, and the upper end 41a is bent upward at 90 degrees. It is formed by bending the upper half outward at 45 degrees and the lower end portion 41b outward at 90 degrees. The bottom plate 42 is bent into a saucer shape like the top plate 40, and the upper end is bent outward at 90 degrees to form a horizontal part 42a, and the tip part 42b is shaped like an inverted U. It has a bent shape. 4
3... are stoppers fixed to the inner peripheral surface of the side plate 41 at equal intervals, and when the top plate 40 is fitted to the upper end 41a of the side plate 41 from above, the outer bottom surface of the top plate 40 is fixed. is supported from below, and is provided so that the upper end of the top plate 40 and the upper end of the side plate 41 are at the same position on the horizontal line.

First, the lower end portion 41b of the side surface 41 is placed on the horizontal portion 42a of the bottom plate 42, and both are welded.The top plate 40 is fitted onto the upper end portion 41a of the side surface plate 41, and the stopper 43 ... and weld the fitting surfaces of both. At this time, the side plate 41
Since the upper end portion 41a of the welded portion 44 is bent, a V-shaped groove 45 is formed in the upper portion of the welded portion 44. Specifically, the maximum width of this V-shaped groove 45 is 3 mm.
Note that this V-shaped groove 45 is formed in the upper end portion 4 of the top plate 40.
It may be formed by bending 0a inward, or it may be formed by bending both.

A paste-like silicone agent 46 is loaded into the V-shaped groove 45 as a water sealant, and the bottom plate 4
A silicone agent 48 as a water sealant is also filled in a gap 47 between the bent base of the tip portion 42b of No. 2 and the lower end portion 41b of the side plate 41. In this loading operation, the former only needs to be loaded into the groove 45, and the latter has a curved tip 42b, so there is no risk of injury from the end surfaces of the side plates 41 and bottom plate 42 during the loading operation. Extremely low and easy to work with. Furthermore, regarding the tip portion 42b of the bottom plate 42,
By making it curved, the strength is increased and the tip part 42
The incidence of dimensional errors near b is extremely low. Furthermore, since the upper end 41a of the side plate 41 is bent at 45 degrees to form the V-shaped groove 45, a sufficient reinforcing effect can be obtained, and the L-shaped Compared to the case where the side plate 41 is bent into a shape, the area of the side plate 41 may be smaller, and it is superior in terms of cost.

The cleaning chamber 3 assembled as described above consists of the machine frame 2
At this time, the distance a between the upper surface 2a of the frame portion 35 and the upper end of the top plate 40 is approximately 5 mm.
Set as below. That is, when the frame body part 35 is bent downward due to pressure from above, the interval a is set such that it can be supported by both upper end surfaces of the V-shaped groove 45 (therefore, they may be in contact with each other). ). In this embodiment, the limit value of this distance a is about 5 mm, and this value can be changed depending on the material and thickness of the frame portion 35.

(g) Effects of the invention In the present invention, a filter cover is attached to the frame of the dishwasher frame and the frame is stored, so there is no need to use a separate reinforcing member. Deformation of the frame body can be prevented. Therefore, the assembly work can be carried out efficiently.

Moreover, since we cut out the rear corner of the frame,
When installing the product, the sense of depth seen from the front is alleviated.
