Abstract

A retaining structure preventing the movement of a seal (20), said retaining structure comprises a lug (131) configured on a cover (13) mating the shape of a detergent receptacle (10a), a groove (133) positioned at the perimeter of said lug (131) and wherein the seal (20) can be positioned, and at least one retaining member (132) configured around the lug (131) at said groove (133). Said retaining member (132) having a surface, said seal (20) being located in use between said groove (133) and said surface, thereby preventing the seal (20) getting out of the groove (133) by contacting with the seal (20) with said surface.

The retaining structure is suitable for a detergent dispenser of a dishwasher.

Description

TECHNICAL FIELD

The present invention is related to a retaining structure enabling the seal to be adapted on the section closing the detergent receptacle in detergent boxes.
The present invention is especially related to a retaining structure enabling the seal to be adapted on the section closing the detergent receptacle in detergent boxes of dish washers.

PRIOR ART

Dish washers comprise detergent boxes which are generally used by being adapted at the cover and dispensing the cleaning material therein into the washer by being opened at a determined time during the washing program.
Detergent boxes have receptacles where different kinds of materials are positioned. One of said receptacles is the detergent receptacle where detergent that will clean the objects to be washed is put. The detergent receptacle is opened at a desired time during the washing and the detergent therein circulates within the washer by being pushed with the water pressure. Therefore, hygiene of the objects to be cleaned is provided.
The washing program comprises several steps before dispensing the detergent in the washer. Meanwhile, the detergent receptacle is required to be completely isolated from the inside of the washer. Otherwise, if a leakage is experienced, the washing cannot be performed with desired performance. Therefore, seals are adapted on the section of detergent boxes which cover the detergent receptacle. The seal is a material such as gasket and the like, and surrounds the receptacle and prevents the detergent leakages into or from the detergent receptacle.
In the state of art, a groove and lugs extending outwards around said groove are configured during the production of detergent box in order to ensure the adaptation of seals onto the cover. After the seal is located into the groove, said lugs are melted by means of resistor and bended so as to hold the seal. Thus, the seal is prevented from getting out of the groove. However, bending the lugs as a second process causes difficulty of use. This situation especially causes the process period to be longer and the labor costs to be higher, in terms of serial production.
As a result, the above mentioned problems require making a development in the related technical field.

BRIEF DESCRIPTION OF THE INVENTION

In order to eliminate the above mentioned disadvantages and to offer new advantages in the related technical field, the present invention is related to a new retaining structure developed for the seals used in the detergent receptacles of dish washers.
The primary object of the present invention is to disclose a retaining structure in order to adapt the seals on the cover of detergent receptacle in a practical manner.
In order to achieve all the objects mentioned above and to be understood from the detailed description below, the present invention is related to a retaining structure preventing the movement of seal by being used together with at least one detergent receptacle, an inner cover closing said detergent receptacle and a seal positioned so as to surround the detergent receptacle on said inner cover. Said retaining structure is characterized in that it comprises a lug configured on the inner cover in accordance with the form of detergent receptacle, a groove adjacent to said lug and configured so as to surround thereof, and where seal is positioned, and at least one retaining member configured around the lug so as to have an area enough for the seal to be located between said groove and thereof, and preventing the seal getting out of the groove by contacting with the seal through a sufficiently broad surface.
In order for the embodiment of the present invention to be better understood together with the additional members and advantages thereof, it is required to be evaluated with the figures described below.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the novelty according to the present invention is only described for the subject to be understood better by way of examples, without any limiting effect. Accordingly, a retaining structure developed to be used in the cleaning boxes of dish washers is described in the description and figures below. However, said retaining structure can be used with different apparatuses, with small changes that will be made thereon.
Figure 1 is the cross-sectional view of a cleaning box (10) assumed to be used with the retaining structure according to the present invention. Accordingly, the cleaning box (10) generally comprises a detergent receptacle (10a) where the detergent is put, an inner cover (13), and an outer cover (12) that is in contact with said inner cover (13) and serves as a closer for the entire cleaning box (10).
Figure 2 is the view of the inner cover (13). Accordingly, a lug (131) configured on the section of inner cover (13) which closes the detergent receptacle (10a) so as to have a form in line with the detergent receptacle (10a), retaining members (132) configured around said lug (131) at certain distances so as to preferably have semi-C form, and a groove (133) adjacent to the lug (131) and configured so as to surround thereof.
A seal (20) complying with the diameter of the groove (133) is positioned into said groove (133). When said seal (20) is positioned into the groove (133), it contacts with all retaining members (132) through the inner surface of semi-C form. The contact surfaces of retaining members (132) are configured so as to have broadness that will enable holding the seal (20) during the back and forth motion of the cover and preventing thereof from getting out of the groove (133).
The retaining members (132) according to the present invention are formed during the production of the inner cover (13), serves as preventer for the seal (20) without requiring any additional process after the seal (20) is positioned into the groove (132), and prevents the seal (20) from getting out of the groove (133).

Claims

A retaining structure preventing the movement of the seal (20) by being used together with;
- at least one detergent receptacle (10a),

- an inner cover (13) closing said detergent receptacle (10a), and

- a seal (20) positioned on said inner cover (13) so as to surround the detergent receptacle (10a),
characterized in comprising;
- a lug (131) configured on the inner cover (13) in accordance with the form of detergent receptacle (10a),

- a groove (133) adjacent to said lug (131) and configured so as to surround thereof, and where seal (20) is positioned, and

- at least one retaining member (132) configured around the lug (131) so as to have an area enough for the seal (20) to be located between said groove (133) and thereof, and preventing the seal (20) getting out of the groove (133) by contacting with the seal (20) through a sufficiently broad surface.
