[0001]

[Industrial applications]

 The present invention relates to a bath cleaning device capable of automatically cleaning the inside of a bath.

[0002]

[Prior art and its problems]

 There is a cleaning device that automatically cleans the inside of the bathtub by ejecting cleaning water containing a cleaning agent from the nozzles on the back of the bath lid or the nozzles on the inner wall of the bathtub and spraying it onto the inner wall of the bathtub. However, in such a cleaning device, since the cleaning water spouts vigorously from the nozzle, if the shape of the bath lid covered on the upper surface of the bathtub is flat, the sprayed cleaning liquid will not flow between the bath lid and the bathtub. There is a problem that it is easy to leak from the space between the upper surfaces to the outside, and if the cleaning liquid leaks to the outside, the amount of the cleaning liquid decreases, so the cleaning efficiency deteriorates and additional cleaning liquid must be added.

[0003]

[Means for Solving the Problems]

 The present invention was devised in view of the above conventional problems, and an object thereof is not to provide a bath cleaning device in which cleaning liquid does not leak to the outside, and the gist thereof is to provide hot water supplied from a heat source device. Circulation in which cleaning water with detergent added is sprayed from the nozzle on the back of the bath lid or the inner wall surface of the bathtub toward the inner wall surface of the bathtub to wash the bathtub, and the wash water after cleaning is circulated to the heat source device. In a bathtub cleaning device having a passage formed therein, the bath lid is provided with a step portion that is in contact with the upper surface of the handrail portion of the bathtub and the inner surface of the side wall portion.

[0004]

[Action]

 The bath lid is provided with a stepped portion, and when the bath lid is covered on the upper surface of the bathtub, the stepped portion contacts the upper surface of the handrail portion of the bathtub and the inner surface of the side wall portion of the bathtub, and The bath lid comes into contact with the inner peripheral edge over a large area, and the cleaning water that is vigorously ejected from the nozzle does not scatter to the outside because the bath lid is not flat like the conventional one, and the cleaning liquid Can be prevented from decreasing.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a bathtub cleaning apparatus. In a bathtub 1, a side wall portion 1b is integrally formed on the outer periphery of a bottom surface 1a in a rising shape, and a handrail portion is protruded outward at an upper end portion of the side wall portion 1b. 1c is integrally formed, and a drain port 1d is formed in the bottom surface 1a in the shape of a recess downward.

A bath lid 2 is covered on the upper surface of the bathtub 1, and the bath lid 2 is configured by a main plate 2 A and a sub plate 2 B that are foldably connected by a butterfly plate 4. A plurality of nozzles 3 are provided on the back surface of 2A, and washing water can be jetted from the nozzles 3 into the bath 1. Further, a concave portion 2b is formed in a concave shape on the back surface of the sub plate 2B, and when the sub plate 2B is folded with respect to the main plate 2A, the nozzle 3 is housed in this concave portion 2b, and the sub plate 2B is the main plate. It is folded in a thin state on the back side of 2A. A nozzle 5 is also provided on the inner wall of the bath 1 so that the cleaning water can be jetted from the nozzle 5.

A drainage path 7 is formed at the bottom of the drainage opening 1d via a valve 6, and a circulation path 8 is connected to the side surface of the drainage opening 1d. The circulation path 8 is connected to a heater 10 via a valve 9, and a pipe 13 having a pump 12 is connected to the heater 10, and an end of the pipe 13 is inside the main plate 2A of the bath lid 2. And is connected to the nozzle 3 by being communicated in a buried manner. Further, a detergent feeder 15 is provided on the upstream side of the pump 12 in the pipe 13 via a valve 14, and the detergent can be fed into the detergent feeder 15. Further, the valve 9 is connected to a water supply channel 11 connected to an external water pipe or the like. Further, a pipe 16 branched from the pipe 13 is connected to the nozzle 5.

In such a structure, the water supplied from the water supply passage 11 is heated by the heater 10 and is pumped by the pump 12 to be ejected from the nozzles 3 and 5 into the bathtub 1. Since the detergent put in is mixed with the detergent, it is sprayed as cleaning water containing detergent onto the inner wall surface of the bathtub 1, and the cleaning water sprayed on the inner wall surface automatically cleans the bathtub 1, and after cleaning, The cleaning liquid is stored in the drainage port 1d of the bath, passes through the circulation path 8 and is returned to the heater 10 to be reheated, and is ejected from the nozzles 3 and 5 via the pump 12.

In this example, the pump 12 is capable of intermittently pumping the cleaning water to the nozzles 3, 5 side, and the pump 12 is turned on and off intermittently via a control device (not shown). There are cases where the pump 12 is turned off and pumps the cleaning water intermittently to the nozzles 3 and 5, and cases where the pump 12 itself has a structure in which an impeller or the like capable of intermittently pumping the cleaning water is incorporated. When the cleaning water is continuously ejected, a water film is formed on the inner wall surface of the bath to reduce the cleaning effect. However, when the pump 12 intermittently pumps the cleaning water, the nozzle 3 and Since the cleaning water is jetted intermittently from No. 5, a new cleaning liquid is constantly sprayed so as to hit the inner wall surface of the bathtub without forming a water film on the inner wall surface of the bathtub. A high cleaning effect can be obtained by hitting.

Further, in order to prevent the jetted cleaning liquid from splashing to the outside, in this example, a stepped portion 2a is formed on the outer peripheral backsides of the main plate 2A and the sub plate 2B of the bath lid 2. Has become. That is, as shown in an enlarged view of the main part in FIG. 2, the outer peripheral side of the step portion 2a of the bath lid 2 is formed thin, and the inner side of the step portion 2a is formed thick, and the handrail 1c of the bathtub 1 is formed. The stepped portion 2a contacts the upper surface of the wall and the inner surface of the side wall portion 1b, and the contact area is larger than that of the conventional flat-shaped bath lid. Scattering can be prevented well. Therefore, the washing water does not leak and decrease, and it is possible to obtain a good washing effect without adding a washing liquid during washing.

In order to prevent the wash water from splashing to the outside even more favorably, as shown in FIG. 3, a protrusion 2c for further increasing the contact area is integrally formed in a drooping shape to form a stepped portion 2a. The bath lid 2 may be formed in a shape with an increased contact portion. As shown in FIG. 4, when the stepped portion 1e is formed on the bathtub 1 side to increase the contact area, the bath lid 2 may be lifted up, and the washing water is collected in the stepped portion 1e. It is easy, and this part is dirty and difficult to clean, and it is more effective to form a step on the bath lid 2 side to increase the contact area.

Further, by forming the step portion 2a on the bath lid 2 side, the inner thickness of the step portion 2a can be increased, and therefore, the nozzle 3 and other components such as pipes are provided in the bath lid 2. It is possible to satisfactorily store it in a buried state. Further, when the bath lid 2 is covered on the upper surface of the bathtub 1, since the bath lid 2 is visually recognized as a thin shape from the outside, the overall appearance is extremely good.

In this example, the nozzle 5 is provided on the inner wall surface of the bathtub 1. However, the nozzle 5 may not be provided, and the cleaning water is sprayed only from the nozzle 3 on the bath lid 2 side. It can also be a device that can be taken out.
