DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher having a structure in which a washing chamber is opened and closed by a hood-shaped door which is turned up and down.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Publication No. 61-14355, a frame which is covered with a stainless steel panel on an upper part of a main body and has an opening on one side is provided. There is a dishwasher which is rotatably supported to open and close an opening and has a hood-like door which forms a washing chamber together with a frame.

[0003] Here, the same type as the above-mentioned dishwasher,
Dishwashers with doors at the front and back are shown in FIGS. The door 1 of the dishwasher 10 partially enters the frame 2 and opens and closes. The door 1 as well as its left and right sides 1a,
Although an appropriate clearance is provided between the left and right side surfaces 1a and 1a of the frame 1 when the door 1 is opened and closed, an appropriate clearance is provided between the left and right side surfaces 1a and 1a of the frame 1 when the door 1 is opened and closed. The inner surfaces of the left and right side surfaces 2a, 2a may come into contact with each other. The contact point is indicated by a hatched portion 3. In addition, 1
c is a handle of the door 1, 4 is a window portion that looks through the washing room, and 5 is a washing machine body.

As a result, the outer surfaces of the left and right side surfaces 1a, 1a of the door 1 are rubbed and markedly impaired in appearance. In order to prevent this, conventionally, for example, as shown in FIG. 7, a roller 6 is used to keep the distance between the door 1 and the frame 2 constant, or to sufficiently prevent the distance between the door 1 and the frame 2 from contacting. There is a method such as taking a structure.

[0005] However, the former method has a problem that costs are required, such as the necessity of roller parts, and the latter method has a problem that the width becomes unnecessarily large and the size of the product increases.

Therefore, as a further improved plan, as shown in FIGS. 8 to 11, the restricting pieces 8, 8 formed of a slippery material, for example, a resin, are vertically opposed to the inner edge of the opening 7 of the frame 2 as shown in FIGS. In addition to restricting the lateral movement of the mounting door 1, a method has been proposed in which the door 1 opens and closes by rubbing with the resin-made restricting pieces 8, 8 to avoid direct contact of the entire frame 21 of the door 1. .

[0007]

However, even if a resin having a low coefficient of friction is used for the restricting pieces 8, 8 in the third method, the door 1 can be used.
When the door 1 and the restriction pieces 8 and 8 come into contact with each other because the
As shown in FIG. 1, there is a problem that the rub marks 9 are still formed in a wide range as shown by oblique lines on the lower left and right side surfaces 1a and 1a of the door 1.

[0008] The present invention has been made in view of the above points, and has as its object to provide a dishwasher having an improved rotating door capable of significantly reducing rubbing marks.

According to the present invention, there is provided a frame provided so as to cover a cleaning chamber in an upper portion of a main body, and having an opening for taking in and out an object to be cleaned on a side surface, and a rotating member which is rotated inside the frame when opened. A dishwasher provided with a hood for closing the opening so as to be able to close the opening, a pair of right and left regulating pieces provided on opposite side edges of the opening of the frame to regulate lateral blur when the hood is opened and closed, A dishwasher is provided, which is provided on both sides of the hood, and is provided with a rib that comes into contact with the regulating piece when the hood is opened and closed.

When the hood is closed,
The dishwasher according to claim 1, wherein the dishwasher is provided on a side portion of the hood located in the frame.

[0010]

The contact with the regulating piece provided on the opening edge of the frame is changed from surface contact to point contact by the rib on the side of the door,
The contact point is also limited to only within the range of the rib, and the rubbing mark can be reduced as compared with the conventional case where the regulating piece and the door side face directly contact.

Further, since the ribs are provided on the side portions located in the frame of the closed door, the ribs are not normally exposed to the outside, so that the appearance is good.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

First, the overall structure of a dishwasher will be described with reference to FIG. 1. Reference numeral 10 denotes a hood-type dishwasher inside a main body 5 covered with stainless steel panels.
A washing tank 11 having a water receiving portion 11a integrally formed thereon is provided. The washing water stored in the washing tank 11 is pressurized by the washing pump 12 and is fed from the connecting pipe 13 to the washing nozzles 16, 16 rotatably arranged up and down in the washing chamber 15 through the washing pipe 14 to be pressure-fed. Rack 1
The cleaning is performed by spraying the sprayed ink on the nozzle 7. After washing for a certain period of time, the rinse water is pressurized by a rinse pump 19 from a booster 18 that stores and heats the final rinse water, and the cleaning nozzle 16
The rinsing nozzles 21 and 21 are provided coaxially with the nozzle 16 and finish rinsing is performed.

The washing chamber 15 in which the washing nozzle 16 and the rinsing nozzle 21 are rotatably arranged is provided with a housing provided at the upper part of the main body 5, that is, a front and a rear for storing and taking out an object to be washed, respectively. The frame 2 is formed so as to be covered with the frame 2 having the openings 7 and the hood-shaped door 1 for opening and closing the openings 7. Each door 1, 1 has a pivot leg 1d,
1d and the legs 1d and 1d are
Are pivotally supported by shafts 22 and 22 mounted horizontally at the central portion of the frame, and can be freely opened and closed by a handle, and can be opened and closed by a handle.
As shown in a dashed line, it enters into the frame 2 and opens.

In the structure having such a pair of doors 1, 1, one of the doors 1 is opened and the rack 17 is put into the cleaning chamber 15 through one of the openings 7, and the cleaning and cleaning is performed for a predetermined time. After the rinsing, the tableware can be washed in a flowing manner by opening the door 1 on the opposite side and taking out the inside of the rack.

Here, an appropriate space is provided between the door 1 and the opening 7, but the restricting pieces 8, 8 are attached to the inside of the left and right side edges of the opening 7 facing each other as in the conventional case.
