JPH0574388U - Lid for automatic washing bath - Google Patents

Abstract

(57) [Summary] [Purpose] I would like to obtain a lid with a structure in which the cleaning agent does not remain on the edge of the bathtub after automatic cleaning. [Structure] A step portion 5 is formed on an inner surface of a lid 3 having a heat insulating structure, and the step portion 5 is fitted inside a rounded portion 1 ′ of a bath 1. [Effect] Since the stepped portion 5 of the lid 3 is fitted inside the rounded portion 1 ′, the cleaning agent does not enter therein. Therefore, since the cleaning agent does not remain on the edge 2 of the bath 1 after cleaning, it is not necessary to wipe it off later.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lid for an automatic cleaning bath.

[0002]

[Prior Art]

 As a lid for a bathtub, a flat plate made of wood or plastic is known. Further, a lid having a heat insulating structure is also known for the purpose of keeping heat.

[0003]

[Problems to be solved by the device]

 However, when the lid having the above structure is used as it is for an automatic cleaning bath, there are the following problems.

A. Since the lid is simply put on the edge of the bathtub from above, as shown in FIG. 6, the cleaning liquid penetrates into the gap between the edge 2 of the bathtub 1 and the peripheral portion 3'of the lid 3 and remains there. From here on, you will have to wipe them by hand later.

B. During automatic cleaning, the heated cleaning water strongly hits the inside of the lid 3 and the internal pressure increases, so that the lid 3 is thermally deformed as shown in Fig. 6 or the cleaning water goes out through the gap. There is.

C. If the lid 3 is deformed and a gap is generated between the lid 3 and the edge 2 of the bathtub 1, heat escapes and heat retention deteriorates.

The present invention is to provide a lid for an automatic cleaning bath which does not have the drawbacks described in ac.

[0008]

[Means for Solving the Problems]

 The structure of the automatic washing bath lid according to the present invention is as follows.

A rigidity is formed by forming a peripheral portion that rides on the edge of the bathtub, and forming a step portion that is fitted to the inner wall of the bathtub inside the curve of the bathtub on the inside surrounded by this peripheral portion. An automatic cleaning bath lid comprising a lid body, a heat insulating material layer formed in a portion surrounded by a step portion of the lid body, and a shield layer formed to shield the heat insulating material layer.

[0010]

[Action]

 The lid is attached to the bathtub so that its step fits exactly inside the curve around the inside of the bathtub. Therefore, even if the washing water is jetted at an angle so as to enter between the bath and the lid during the automatic washing, it does not enter the gap. Further, since the lid is fitted to the inner surface of the bath at the stepped portion, it does not float up due to the internal pressure. Further, since the lid shields the heat insulating material layer with the shield layer, water does not enter the heat insulating material layer to lose the heat insulating effect, and the whole lid is not thermally deformed.

[0011]

【Example】

 In FIG. 1, 1 is a bathtub, 2 is a rim, and 3 is a lid. As shown in FIG. 2, the lid 3 is made of a rigid material such as hard plastic or aluminum. The base material 4 and the lid body 4 are lowered inward to form a step 5, the heat insulating material 6 is attached to the inside of the lowered portion, and the shield layer (resin layer) 7 is formed on the upper surface. This is a structure in which the heat insulating material 6 is shielded.

As for the structure of the lid 3, as shown in FIG. 3, an air layer 8 may be formed between the heat insulating material 6 and the shield layer 7. Further, as shown in FIG. 4, a step portion 7 ′ may be formed on the shield layer 7 side so as to be lowered by one step.

FIG. 5 shows a fitting structure of the bathtub 1 and the lid 3, in which the peripheral edge portion 3 ′ of the lid 3 rides on the edge 2 of the bathtub 1 and the step portion 5 is placed inside the rounded portion 1 ′ of the bathtub 1. Mating. As a result, even if the cleaning water is sprayed to the fitting portion as shown by the arrow, the fitting water does not penetrate into the space 9 including the rounded portion 1 ′ and the close contact portion between the edge 2 and the lid 3. Absent.

[0014]

[Effect of the device]

 The effects of the present invention are as follows.

A. A step portion was formed inside the lid, and this step portion was fitted inside the radius of the bathtub. As a result, there is no concern that the cleaning agent will enter and remain in the peripheral portion of the bathtub including the rounded portion, so there is no need to wipe it off later.

B. Since the stepped part of the lid is fitted on the bath side, the lid does not float up or slip off due to internal pressure during automatic cleaning. As a result, there is no concern that the cleaning water will be scattered and heat will not escape.

C. Since the lid has a heat insulating structure, the lid will not be deformed by heat during cleaning and the heat retention will be improved.

D. Since the heat insulating material is shielded by the shield layer, water does not enter the heat insulating material layer and the heat insulating effect is not lost.
