Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath apparatus, and more particularly to a bath apparatus, in which hot water in a bath tub is forcibly circulated, while filtering, sterilizing, and other cleaning treatments are performed, and at the same time, the bath temperature is maintained at a bath temperature. The present invention relates to a so-called 24-hour bath apparatus which is capable of taking a bath at any time for 24 hours while keeping a bath at any time.

[0002]

2. Description of the Related Art Recently, bathtub hot water purifiers have been actively used, which keep the hot water in a bathtub constantly clean and at an appropriate temperature, allow comfortable bathing 24 hours a day, and save water.

[0003] An example of such a bathtub hot water purifier is shown in FIG. 8, wherein 1 is a bathtub, 2 is hot water, 3 is a hot water suction pipe for pumping hot water 2 in bathtub 1, and 4 is a hot water suction pipe. An apparatus main body in which devices for cleaning the hot water pumped up by the water suction pipe 3 are collectively provided, and 9 is a fountain pipe for ejecting the hot water treated by the apparatus main body 4 into the bathtub 1 again. .

In order to remove dirt from the hot water, the apparatus main body 4 is provided with a filtration tank 5 containing various types of granular filter media such as activated carbon, activated stones, and porous ceramic balls, and a fibrous filter alone or in combination. Pumps for forcibly circulating water, a sterilizing tank 7 provided with an ultraviolet killing lamp for sterilizing hot water, a heating tank 8 provided with a heater for maintaining hot water at an appropriate temperature, etc., are connected in series with cleaning equipment. Has been deployed.

[0005] The bathtub 1 is provided with a hot water suction unit 10 for sucking hot water to be cleaned and a hot water unit 11 for spouting hot water that has been subjected to the cleaning process again. 3 is connected to the fountain unit 11 at the tip of the fountain pipe 9.

[0006] As shown in FIG.
A pre-filter 13 for removing large dirt is accommodated in a filter case 12 and closed by a filter case lid 14 provided with a water inlet 15.

Although not shown, the fountain unit 11 jets the purified water from the fountain port 16 into the bathtub 1 as a jet while mixing the air sucked from an intake pipe connected to the ejector unit. It is configured as a jet nozzle for a bubble bath.

Therefore, when the circulating pump 6 is operated by the apparatus constructed as described above, the hot water 2 in the bathtub 1 is sucked through the hot water inlet 15 of the hot water unit 10 and is first passed through the pre-filter 13 in the filter case 12. The large dirt is removed and enters the apparatus main body 4 through the water suction pipe 3.

The hot water that has entered the apparatus main body 4 is filtered in a filtration tank 5, sterilized in a sterilizing tank 7, kept warm in a heating tank 8, and subjected to a cleaning treatment. After 9, jets are jetted out of the hot water port 16 of the hot water unit 11 as a jet flow. At this time, if a valve is opened and air is sucked from an intake pipe, a bubble bath is formed.

As described above, when the cleaning process of the hot water 2 in the bathtub 1 is continued, the pre-filter 1
The filter medium filled in the filter tank 3 and the filter tank 5 becomes dirty and clogged, and the amount of hot water flowing through the cleaning pipe is reduced.

When the cleaning pipe is clogged and the flow rate of hot water decreases, the effect of the cleaning process naturally declines and the bathtub 1
Hot water 2 inside will not be clean.

When the cleaning pipe is clogged and the flow rate of hot water decreases, a small amount of hot water is heated to a high temperature in the heating tank 8, and as a result, a small amount of hot water is heated to the fountain unit 11. Squirt into the bathtub 1 from the hot spring port 16 of the bathtub 1
As for the temperature of the hot water inside, unevenness occurs in which the upper part is high and the lower part is low.

Further, in the heating unit 8, since the temperature of the hot water sucked from the hot water suction unit 10 is detected by a sensor and the hot water is heated while controlling the heater, if the temperature of the lower hot water in the bathtub 1 is low. The temperature of the hot water sucked from the hot water suction unit 10 is low, the heater of the heating unit 8 keeps heating the hot water, and the hot water continues to squirt upward, and the temperature unevenness becomes more and more severe.

Further, when the cleaning pipe is clogged and the flow rate of the hot water decreases, the momentum of the hot water spouting from the hot water unit 11 decreases, and at the same time, the amount of the air sucked from the suction pipe decreases, so that the effect as a bubble bath can be obtained. It will be lower.

As described above, various problems occur when the cleaning pipe is clogged and the flow rate of the hot water is reduced. Therefore, the pre-filter 13 of the hot water absorption unit 10 and the filter medium of the filtration tank 5 are cleaned of dirt attached thereto. Cleanliness must be constantly managed to avoid clogging.

In order to prevent the filter medium of the filtration tank 5 from becoming dirty and clogging the pipeline, many apparatuses are provided with an automatic backwashing device. It is automatically dropped by back washing, and after several months, the filter medium is taken out of the filtration tank 5 and washed or replaced.

The pre-filter 1 of the hot water unit 10
In No. 3, since a large amount of dirt is attached and clogging is likely to occur, it is necessary to frequently remove the dirt from the filter case 12 and remove the dirt.

[0018]

However, since the pre-filter 13 is left to the user who is busy in daily life, it cannot be easily cleaned as instructed in the instruction manual.

For this reason, the pre-filter 13 is so dirty that it is easily clogged. However, if various problems occur due to the above-mentioned clogging of the pipeline, the user mistakenly thinks that the apparatus has failed. It often takes time to take appropriate measures.

In order to automatically detect clogging of a pipeline and notify a user of the clogging, a water flow sensor for detecting a flow rate is provided in a conventional pipeline, or a pressure difference between a suction side and a discharge side of a circulation pump is detected. For example, a differential pressure sensor is provided, and the detection result of such a sensor is displayed on a display device.

However, if a sensor is provided in a pipe, the cost increases first, and even if a sensor is provided in a pipe in which dirty water flows, no matter how precise the sensor is provided, if the sensor becomes dirty, it malfunctions and becomes too accurate. Clogging of pipelines could not be detected.

The present invention solves the above-mentioned drawbacks of the prior art, and cleans a bathtub hot water provided with an automatic pre-filter and a pipe line clogging detecting means capable of informing a user of clogging accurately at a low cost. It is an object to provide a chemical conversion device.

[0023]

That is, according to the present invention, a circulation pump is operated to draw hot water in a bathtub from a hot water suction unit via a hot water suction pipe, and sterilization in a sterilization tank in the apparatus main body, and sterilization in a filtration tank. In a bathtub hot water purifying apparatus in which predetermined cleaning processing such as filtration and heating in a heating unit is performed and the jet water is jetted again from the hot water unit through a hot water pipe into the bathtub, the hot water flow rate of the hot water at the hot water spout or the spout port is controlled. A rotatable clogging display plate is provided accordingly, and if the flow rate of hot water is reduced due to clogging of a pipeline, the clogging display plate is turned to a visible position.

The clogging display plate may be an impeller that is attached to a hot water inlet of the hot water unit and rotates to a visible position through a confirmation window when the pipeline is clogged, or a fountain of the hot water unit. An inclined plate that pivots between a horizontal and a vertical opening / closing position in accordance with the amount of the hot water with respect to the mouth, and is located at a vertical closed position to be visible when the pipeline is clogged,
It is configured to be inexpensive, operate accurately in accordance with the flow rate of hot water, and notify a user of clogging accurately.

[0025]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described first with reference to a first embodiment shown in FIGS.

In the first embodiment, a water suction port 1 of a water suction unit 10 is used.
This is an example in which a clogging display plate that rotates in accordance with the amount of hot water flowing into the water bath 5 is provided. As shown in FIG. A confirmation window 17 is provided at an appropriate position so that the inside of the appropriate size can be seen through.

Reference numeral 18 denotes an impeller as a clogging display plate as shown in FIG. 2, and the impeller 18 is a fan-shaped plate which rotates around a required position, and the surface of the fan-shaped plate The mounting boss 20 is provided with a bearing hole for fitting the mounting shaft at a required position serving as a center of rotation on the rear surface, and simultaneously flows radially from the required position. A plurality of blade ribs 19 for projecting the resistance of the hot water and rotating the plate are provided.

The impeller 18 configured as described above is
The bearing hole of the mounting boss 20 protruding from the rear surface is rotatably fitted to the mounting shaft, and is attached to the water suction port 15 of the water suction unit 10 at a position behind the confirmation window 17.

Then, when hot water is not flowing at all at the suction port 15 or hot water is not flowing at all, or when the flow rate of hot water is very small even if the hot water is operated, the impeller 18 does not rotate at all due to the flow of hot water. As shown in FIG.
It is located in a state where the color applied to the surface can be visually checked from.

On the other hand, when the apparatus operates and a large amount of hot water flows, the impeller 18 is rotated clockwise by the force of the hot water, and as shown in FIG. It is located in a state where the color applied to the surface cannot be seen at all.

Therefore, when the apparatus is operated and a large amount of hot water is sucked in and the color painted on the surface of the impeller 18 is not seen at all through the confirmation window 17 of the hot water inlet 15, not only is there no abnormality in the apparatus but also the pipe line is visible. You can enjoy bathing as it is not clogged.

On the other hand, when the amount of hot water sucked in is small and the color of the surface of the impeller 18 is visible in the confirmation window 17 of the hot water inlet 15, there is something wrong with the device or the pipeline is clogged. Therefore, the user first opens the filter case lid 14 of the hot water unit 10, takes out the pre-filter 13, and cleans it.

If the cleaned pre-filter 13 is stored in the hot water absorption unit 10 and the apparatus is operated again, and the color painted on the surface of the impeller 18 cannot be seen from the confirmation window 17 at all, the clogging of the pipe line may occur. You can continue driving as it is.

On the other hand, when the color painted on the surface of the impeller 18 is visible in the confirmation window 17, for example, a lot of dirt is attached to equipment other than the pre-filter 13 such as the filtration tank 5, and the pipeline is clogged. The user cannot easily take action depending on whether the device is out of order or if some device is out of order.

As described above, the confirmation window 1 of the hot water absorption unit 10
The device can be properly managed only by checking whether the color painted on the surface of the impeller 18 can be seen at 7, and the pre-filter 13, which can be easily washed by the user, is simply clogged with dirt. There is no need to receive service, and at the same time, for example, the circulation pump 6 runs idle,
There is no need to worry about the failure of the heater of the heating tank 8 causing the heater to be idle and to cause a major accident.

Next, the spout is rotated with respect to the spout 16 of the spout unit 11 in accordance with the amount of flowing hot water, and the pipe is clogged. This will be described. That is, a second embodiment in which a clogging display plate which rotates in accordance with the amount of flowing hot water and displays clogging of a pipeline with respect to a fountain opening 16 of the fountain unit 11 is provided will be described with reference to FIGS. I do.

In the second embodiment, a transparent protective tube 23 is placed over the fountain opening 16 of the fountain unit 11 projecting into the bathtub 1.

Reference numeral 21 denotes an inclined plate provided as a clogging display plate with respect to the spout 16. The lower end of the inclined plate 21 is rotatable by a protective case 23 which is covered at a front position with respect to the spout 16. The surface facing the bather is painted with, for example, a red identification color.

A balance 22 extending downward is attached to the center of the lower end of the inclined plate 21, whereby a force for rotating the inclined plate 21 in the counterclockwise direction by the pressure of the hot water spouted from the spout 16 is provided. At the same time, the inclined plate 21 rotates to the clogging display position only when the amount of hot water spouted from the spout 16 becomes an appropriate amount for detecting clogging. I have.

That is, FIGS. 4 and 5 show a state where the pipeline is not clogged and the amount of hot water spouting from the spout 16 is large. At this time, the inclined plate 21 is the spouting hot water. Since it receives a large pressure, it rotates counterclockwise and is located at an open position horizontal to the fountain port 16.

On the other hand, FIGS. 6 and 7 show a state in which the pipe is clogged and the amount of hot water spouting from the spout 16 becomes less than a certain amount. 21 is a spouting hot water that does not receive too much pressure,
To rotate clockwise with the force of.

Then, the bather 24 clearly sees the inclined plate 21 by the identification color, and knows that the pipeline is clogged, so that the above-mentioned appropriate treatment can be taken.

[0043]

The present invention is constructed as described above, and has a very simple structure, such as a display plate which automatically rotates according to the amount of hot water flowing into a hot water inlet or a hot water outlet, is hard to malfunction, and can be manufactured at a low cost. The bather can easily recognize the clogging visually.

As a result, the user can easily take an appropriate action when using the apparatus, and can easily receive the service of the maker even though the pre-filter which can be easily washed is dirty and clogged. At the same time, for example, the circulation pump runs idle,
This eliminates the risk of overlooking a failure such as an empty heating of the heating tank heater and causing a major accident.
