Description

[Technical field]

[0001] The present invention relates to a bathtub cleaning device that is attached to a bathtub lid and is used to clean the inside of an empty bathtub. [Background technology]

[0002] Conventionally, the typical cleaning method is to spray detergent into the bathtub, wipe off the dirt with a sponge or the like, and then rinse off the detergent and dirt in the shower. However, this method requires bending over when spraying the detergent or wiping off with a sponge or the like, which can be problematic for workers, especially elderly people, as it requires them to work in uncomfortable positions.

[0003] Therefore, a bathtub cleaning device has been developed which is equipped with a main body configured to float in bath water, a water supply port provided at a designated position on the main body, a nozzle for spraying water supplied from the water supply port, and a pump for supplying bath water from the water supply port to the nozzle, the nozzle being located above the bath water level, the main body being floated on the remaining water in the bathtub, the bathtub drain plug being removed and the tub lid being placed on the bathtub to drain the remaining water, the cleaning switch being pressed to start operation of the main body, the bath water that has been sucked up being sprayed from the nozzle and evenly sprayed onto the walls of the bathtub, making it possible to clean dirt inside the bathtub (see, for example, Patent Document 1).

[0004] This bathtub cleaning device can automatically and economically clean the dirt from the bathtub by using the remaining water in the bathtub, eliminating the need to bend over during manual cleaning. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2000-93338 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the above-mentioned conventional technology, since it is electrically operated, the risk of electric leakage cannot be denied, and since it uses leftover water with floating dirt, it is necessary to take measures to remove it such as a filter. Furthermore, there were problems that had to be solved, such as the impossibility of cleaning the inner bottom of the bathtub, where dirt and stubborn slime accumulate. [Means for solving the problem]

[0007] In consideration of the problems associated with the above-mentioned conventional technologies, such as the risk of electric leakage, the need for a means of removing dirt, and the inability to clean the inner bottom of the bathtub, the present invention solves the above-mentioned problems by forming a water supply channel that penetrates vertically through a base material that can be placed between a pair of adjacent lid panels of a bathtub lid that can be divided into multiple lid panels, or a bathtub lid that covers the bathtub, making it possible to connect a water supply hose to the inlet of the water supply channel, and removably attaching a spray unit to the outlet of the water supply channel, thereby making it possible to clean the inner wall and inner bottom surfaces of the bathtub using only the water pressure from the tap water, which contains very few impurities. Effect of the Invention

[0008] In short, the present invention forms a water supply passage that penetrates vertically through a base material that can be placed between a pair of adjacent lid panels of a bathtub lid that can be divided into multiple lid panels, makes a water supply hose connectable to the inlet part of the water supply passage, and has a spray part that is removably attached to the outlet part of the water supply passage, so that existing split bathtub lids can be used, and by simply covering the bathtub with the lid panels connected by the base material, connecting the water supply hose to the connection part and starting the water supply, the cleaning water can be sprayed evenly onto the inner wall and inner bottom surfaces of the bathtub without splashing the cleaning water around, and can clean even the inner bottom surface of the bathtub where dirt and stubborn slime tend to accumulate, eliminating the need for manual cleaning work.

[0009] By forming insertion slits for the inner end of the lid panel on both sides of the base material, it is possible to improve the integrity of the lid panel and the base material, and no gaps are created between the lid panel and the base material, thereby further improving the function of preventing cleaning water from splashing around.

[0010] A water supply passage is formed that penetrates the bathtub lid from top to bottom, a water supply hose can be connected to the inlet of the water supply passage, and a spray unit is removably attached to the outlet of the water supply passage.By simply covering the bathtub with this bathtub cleaning device, connecting the water supply hose to the connection unit and starting the water supply, the cleaning water can be sprayed evenly onto the inner wall and inner bottom surfaces of the bathtub without splashing the cleaning water around, and the inner bottom surface of the bathtub, which is particularly prone to accumulation of dirt and stubborn slime, can be cleaned, eliminating the need for manual cleaning work.If the water supply hose and spray unit are removed, the device can be used as a normal bathtub lid, and has extremely great practical effects.
