[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bathtub hot water purifying device that cleans the bathtub hot water using various devices, and in particular, the clogging of the filter is detected by detecting the hot water flow state in the circulation path of the bathtub hot water cleaning device. It relates to a device for knowing the state.

[0002]

[Prior art]

 Recently, the hot water in the bathtub is forcibly circulated in a circulation path equipped with various cleaning devices by a circulation pump, and dirt such as dirt and hair suspended in the hot water is filtered by a filtration device and activated. A bath water purifying device that purifies hot water by activating it in a stone tank or sterilizing it with a sterilization device has been developed and has been widely used.

More recently, in addition to simply purifying hot water, an electric heater for keeping warm water is also provided in order to keep the temperature of the hot water constantly at an appropriate temperature and to be able to comfortably bathe at any time for 24 hours. A jet nozzle is provided at the outlet of the purified hot water to the bathtub, and the hot air is jetted as a jet flow together with the air sucked from the intake device from the jet nozzle so that the so-called bubble bath can be enjoyed. became.

The most serious problem in such a bath water cleaning device is clogging of the filter in the filtering device.

That is, in the cleaning device, the filter filter of the filter device becomes clogged with dirt as the treatment progresses, and when the filter is clogged, the circulation amount of hot water is naturally small. The ability to clean the hot water of Natsute declines.

In addition, a jet nozzle having a self-priming intake device is provided at the outlet of the hot water, and the negative pressure generated by the flow of the hot water sucks in air through an intake pipe connected from the intake device, When hot water is jetted as a jet flow together with the generated air to provide a bubble bath function, if the circulation amount of hot water is reduced, the jet output of hot water becomes low and the degree of negative pressure of the intake device also becomes low. The amount of intake air also decreases and the function as a bubble bath decreases.

Further, an ozonizer is provided in the middle of the intake pipe connected to the intake device of the jet nozzle, and the inhaled air is ozoned and the ozonized air is ejected from the jet nozzle into the bath with the hot water to sterilize the hot water. If this is done, the sterilizing power of ozone will also decrease as the intake volume decreases.

As described above, when the filter is clogged, various problems occur. Therefore, the degree of clogging of the filter is constantly checked, and when the filter is clogged, it should be replaced and washed. Need to be

FIG. 3 shows a cleaning device equipped with a conventional filter clogging detection device.

In FIG. 3, 1 is a bathtub containing hot water 2, 4 is a water suction pipe having a pre-filter 3 for filtering large dirt at a tip of the hot water inlet, and 5 is for filtering dirt in hot water. The filter 6 loaded with the filter 6 is a circulating pump 7 for forcedly circulating hot water, 8 is a heater for keeping warm water at an appropriate temperature, and 9 is an activated stone 10 for activating hot water. It is a filled activated stone tank, and these devices are connected in series with each other by connecting pipes 14, 15 and 16.

Reference numeral 11 is a spout tube for spouting the hot water after the cleaning process into the bathtub 1, and the spout port of the spout tube 11 has an intake device 13 for spouting a jet flow. An etch nozzle 12 is attached.

Reference numeral 17 denotes a water flow sensor provided in the connecting pipe 16, and the water flow sensor 17 detects the amount of hot water flowing through the circulation path to know the clogging state of the filter 6.

Reference numeral 18 denotes an intake pipe having one end connected to the intake device 13 of the jet nozzle 12 and having an end open to the atmosphere. The intake pipe 18 has an electromagnetic valve 20 for opening and closing the intake port at the intake port at the tip. A high-pressure discharge type ozonizer 19 for ozone-izing the inhaled air is provided on the way.

In the cleaning apparatus configured as described above, the hot water 2 in the bathtub 1 is sucked up by the operation of the circulation pump 7 while filtering large contaminants from the hot water pipe 4 by the prefilter 3 and indicated by the arrow. After being filtered by the filter 6 of the filter device 5 to remove dirt, it is heated to a proper temperature by the heater 8 and finally activated by the activated stone 10 in the activated stone tank 9 and then from the jet nozzle 11 through the jet nozzle 12 to the intake pipe 18 It is jetted to the bathtub again as a jet flow together with the air taken in from the bath.

In this case, since the ozonizer 19 is provided in the middle of the intake pipe 18 connected to the intake device 13 of the jet nozzle 12, as described above, the jet nozzle 12 causes hot water to be ozonized along with the ozonized air. It is jetted out and the hot water 2 is sterilized by ozone.

In the above-mentioned device, when the filter 6 of the filtration device 5 is clogged and the amount of hot water flowing through the circulation path becomes a predetermined amount or less, the ability of cleaning and sterilizing the hot water decreases. The water flow sensor 17 detects this and sends a certain signal to notify the user so that the filter can be replaced or washed.

[0017]

[Problems to be solved by the device]

 However, as described above, when the flow rate of hot water is detected by the water flow sensor 17 provided in the hot water circulation path, since dirty hot water constantly circulates through the water flow sensor 17, the water flow sensor 17 becomes dirty. There is a risk of malfunctions or malfunctions that may occur due to sticking of foreign matter or catching foreign matter.

For this reason, the water flow sensor 17 is set to have a margin to operate on the safe side, and even if the filter 6 is slightly clogged, a clogging signal is generated. 6 must be replaced and washed.

The present invention solves the above-mentioned drawbacks of the prior art, accurately detects clogging of the filter in the bath water cleaning device, and replaces or cleans the filter unnecessary for the user. The purpose is to be able to maintain good cleaning and sterilizing ability without causing it.

[0020]

[Means for Solving the Problems]

 That is, the present invention is a bathtub hot water purification device in which various cleaning treatment devices are provided in the forced circulation pipeline of the bathtub hot water in which the bathwater is forcedly circulated by the circulation pump. A self-priming intake device that draws in the atmosphere by the negative pressure that accompanies this is installed, and the other end of the intake pipe whose one end is open to the atmosphere is connected to this self-priming intake device. An apparatus for cleaning bathtub hot water is equipped with an intake air amount sensor that detects the intake air amount.

[0021]

[Function of the device]

 The present invention is configured as described above, and when the flow rate of hot water decreases in the circulation path due to the clogging of the filter, the negative pressure is low in the self-priming intake device installed in the circulation path and the suction pipe Since the intake volume decreases, the clogging of the filter can be detected by detecting the change in intake volume with the intake volume sensor installed in the intake pipe connected to this intake system.

Unlike the conventional water flow sensor, the intake air amount sensor is not provided in the hot water circulation path, so it does not get dirty and is constantly operating normally, and the filter clogs the hot water flow rate. It is activated only when the intake air amount becomes less than the specified amount and the clogging of the filter is detected accurately.

[0023]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, and the basic configuration of this cleaning device is the same as that of the cleaning device of FIG. 3 shown above as a conventional example, and therefore, the same device is the same. Is attached.

The difference in configuration between the present embodiment and the conventional example shown in FIG. 3 will be described. First, in the present embodiment, the water flow sensor provided in the connecting pipe 16 which is the circulation path for hot water in the conventional example. 17 is omitted.

Next, in addition to the ozonizer 19 and the solenoid valve 20, the intake pipe 18 is provided with an intake air amount sensor 21 for detecting the intake air amount at the intake port at the tip.

In addition, as a method of supplying air to the jet nozzle 12 attached to the spout opening of the spout tube 11, there is a method of forcibly supplying air by an air pump, but in the present embodiment, Since the self-priming intake device 13 that changes the intake amount according to the change is provided to supply air, it is not necessary to install the intake device specially in the circulation path to detect the change in the intake amount, which is convenient. Is.

FIG. 2 shows an example of a jet nozzle 12 having a self-priming suction device 13. The jet nozzle 12 rotatably fits the spout nozzle 24, the suction device 13 and the spout nozzle 24. The aspirator unit 22 is formed from the nozzle cover 25 to which the spout tube 11 is connected, and the intake unit 13 narrows the flow path of the hot water to increase the flow velocity and forms a negative pressure for automatically sucking air by the bench Yury effect. And an intake port 23 to which the intake pipe 18 is connected.

With the above configuration, when the cleaning process using the device progresses and the filter 6 of the filtration device 5 is clogged and the circulating amount of hot water becomes small, the aspirator of the self-priming intake device 13 is reduced. The flow velocity of the hot water in the portion 22 becomes slow, and the negative pressure degree of the intake port 23 becomes low.

When the negative pressure degree of the intake port 23 becomes low, the intake amount from the intake pipe 18 connected to the intake port 23 naturally decreases and the intake amount decreases. It is detected by the intake air amount sensor 21 provided in the.

Therefore, if the intake air amount sensor 21 constantly detects the intake air amount of the intake pipe 18 connected to the intake device 13, it can be detected that the circulating amount of hot water has decreased in the circulation path. If a signal is generated when the intake air amount sensor 21 detects that the intake air amount has fallen below a predetermined amount, clogging of the filter 6 can be accurately notified.

Further, since the intake air amount sensor 21 is provided in the intake pipe 18 and does not come into contact with dirty hot water at all, there is no concern that the hot water becomes dirty. It does not malfunction or fail as long as the air intake is removed and the dirt is removed.

[0033]

[Effect of the device]

 The present invention has the above-described structure and operation, and the clogging state of the filter can be accurately grasped by the intake air amount sensor provided in the intake pipe connected to the self-priming intake device with almost no fear of malfunction or failure. it can.

Therefore, since the user is properly informed of the clogging of the filter by the intake air amount sensor, it is possible to wash the filter at an appropriate time without unnecessarily frequent cleaning. Doing this will keep your filter clean at all times.

Accordingly, a bath water purifying device that is easy to maintain and has the ability of cleaning and ozone sterilization constantly maintained in good condition is provided.
