Description

[Detailed description of the invention] [Industrial application field] By collecting dirt on the surface of the hot water without overflowing the bathtub and reusing it after heating, it saves water and energy, and keeps the bathtub clean at all times. This invention relates to a deodorizing overblow device that can do the following.

[Conventional technology]

Conventional bathtubs either allow hot water to overflow from the bathtub or only allow over-circulation without providing an overflow, but they have disadvantages such as overflowing the bathtub is a waste, and without an overflow, the surface of the hot water becomes unpleasantly dirty. It was hot.

[Problem that the invention attempts to solve]

This invention attempts to solve the problem that conventional bathtubs cause hot water to overflow from the bathtub, wasting the hot water, and the problem that if there is only overcirculation without an overflow, the surface of the hot water gets dirty and unpleasant. It is.

[Means for solving problems]

An overblow with a collection port at the top and a trap inside is buried in the edge of the bathtub slightly below the upper edge of the bathtub with the collection port facing inward.
The lower part of the overblow and the upper part of the hot water storage tank are connected with an overblow pipe, the lower part of the hot water storage tank and the circulation pump are connected with a pipe via a hair catcher, and the pressure feeding pipe of the circulation pump is connected to the upper part of the sand filter. A hot water supply port is provided at a location on the edge of the bathtub, located higher than the overblow, and the hot water supply port and the lower part of the sand filter are connected with a hot water supply pipe.
Hot water is heated by a heating device such as a boiler, and the overflowing water is dropped into the overflow from the collection port and sent to the hot water storage tank, where it is sent to the sand filter by the circulation pump. A hair catcher filters the hair, a trap prevents the backflow of odors from the hot water tank, a sand filter filters dirt from the bathtub, a heating device heats the water to an appropriate temperature, and the hot water is sent to the bathtub from the hot water supply port. The problem was solved in this way.

[Effect]

The hot water that overflows from the bathtub is collected from the overflow collection port, the overflowing hot water is sent to the hot water storage tank through the overflow pipe, and the hot water that has accumulated in the hot water storage tank is sent to the sand filter using a circulation pump to filter out the entire hot water. However, the hair in the hot water is passed through a hair catcher before being sent to the sand filter.
At overflow, a trap that forms an S-junction to prevent odors prevents odors from flowing back from the hot water storage tank.
Furthermore, hot water is heated to an appropriate temperature by passing a heating device between the hot water supply pipes connecting the sand filter and the hot water supply port.
For example, the heating device uses a vertical heat exchanger.
The hot water in the hot water supply pipe is heated by circulating high temperature hot water or steam from a heating boiler.

〔Example〕

An overblowing device 3 having a collection port 1 at the top and a trap 2 inside is buried in the edge 5 of the bathtub 4 at a location slightly below the upper end of the edge 5 with the recovery port 1 facing inward. The lower part of the blowing device 3 and the upper part of the hot water storage tank 6 are connected by an overblow pipe 7, and the lower part of the hot water storage tank 6 and the circulation pump 8 are connected by a pipe 10 via a hair catcher 9. The pressure feed pipe 11 is connected to the inlet side of the sand filter 12, and a hot water supply port 13 is provided at a place on the edge of the bathtub 4, located higher than the overblow 3. The outlet side is connected with a hot water supply pipe 14, and the hot water supply pipe 14 is heated by passing through a heating device 15 such as a boiler (not shown). The overblow 3 has flat sides and an inverted mountain shape in a front view, and has a socket 16 at its lower end for connection to the overblow pipe 7, and a movable plate 17 for adjusting the water level on the back side of the recovery port 1, which can be moved up and down. It is flexible and extends over the entire width of the collection port. Odor stopper S is placed at the bottom of the overflow 3.
A trap 2 forming a crossroads is provided.
A supply pipe 18 and a discharge pipe 19 from a heating boiler (not shown) are connected to the vertical heat exchanger 15, and hot water in the hot water supply pipe 14 is heated by circulating hot water or steam. be. The outer surface of the overflow 3 is covered with lath to improve adhesiveness.

〔effect〕

To prevent hot water from overflowing from the bathtub, dirt on the surface of the hot water can be collected, heated and reused, saving water and energy, and keeping the bathtub clean at all times.

The figure shows a front view and a side view of the overflow.

Claims (1)

[Scope of utility model registration request] An overblower device with a collection port at the top and a trap inside is buried within the edge of the bathtub, slightly below the top of the edge, with the recovery port facing inward, and the bottom of the overblower is placed over the top of the hot water storage tank. Connect the lower part of the hot water storage tank and the circulation pump with a pipe through a hair catcher, connect the pressure pipe of the circulation pump to the inlet side of the sand filter, and The hot water supply port is located at a location higher than the overblow, and the hot water supply port is connected to the outlet side of the sand filter by a hot water pipe, and the hot water is heated by a heating device such as a boiler. This is an odor-proof overblow device.
