BACKGROUND OF THE INVENTION The present invention relates to a bath device, and more particularly to a bath device having an automatic water filling function. Even if the water pressure gauge for detecting the water level in the bath changes its performance over time, it is affected. It is designed so that it can be filled with water accurately up to the proper water level without being sprayed.

[0002]

2. Description of the Related Art There is a bath apparatus shown in FIG. 1 which has an automatic water filling function for automatically stopping the water filling operation when the hot water for filling water reaching a certain level reaches a certain level. In this bath apparatus, a water filling circuit (17) connecting from the water heater (5) to the bathtub (2) is formed, and the water filling circuit (17) is provided with a water filling valve (4) from its upstream side. The water pressure gauge (34) is inserted in this order.

Further, the water heater (5) and the water filling valve (4) are controlled by a control device (3) incorporating a microcomputer, and the control device (3) includes appliances. A power switch (31) provided on the main body (A) and an operation switch (32) provided on the bathroom wall surface are connected by wiring. After the installation work of the equipment and the like, an initial setting work for determining a reference water pressure (P0), which will be described later, which is necessary at the time of actual filling of water is performed. The water pressure gauge (34) is not constant in the height direction between the equipment body (A) and the bathtub (2) for each equipment to be installed.
Cannot uniformly determine the water level in the bathtub, so an initial setting operation is performed to determine the reference water pressure (P0), which is a reference for determining the water level in the bathtub, for each installed device.

That is, when the power switch (31) is turned on, the water filling valve (4) is opened and the water supplied from the water heater (5) is sent to the bathtub (2) side. Then, when a certain amount of time has elapsed from the start of the water supply and the water supplied from the water heater (5) reaches the bathtub (2), the water filling valve (4) is closed and the water filling valve (4) is closed. Keep the water in the downstream circuit. And in this state, the water pressure gauge (3
The reference water pressure (P0) detected by 4) is stored in the control device (3). Then, at the reference water pressure (P0), the filling water is supplied into the bathtub (2) so that the water level in the bathtub is the filling circuit (1).
The water pressure is equal to the water pressure detected by the water pressure gauge (34) when it is assumed that the water pressure has risen up to the water discharge port (29) at the downstream end of 7). As a result, the initial setting work for determining the reference water pressure (P0) is completed, and the actual water filling described later is performed by using the reference water pressure (P0).

When the operation switch (32) is turned on during the actual filling of water, the water filling valve (4) is opened and the water heater (5) is opened.
The hot water boiled in is supplied to the bathtub (2). And
“Reference water pressure (P0) + Δ” obtained by adding a water head pressure ΔP corresponding to the height difference between the water discharge port (29) opened on the side wall of the bathtub (2) and the set water level (K) suitable for bathing to the reference water pressure (P0).
When the water pressure gauge (34) detects the water pressure "P", the filling operation of the bathtub (2) is stopped. As a result, the water can be filled up to the set water level (K) based on the water discharge port (29) formed on the side wall of the bathtub (2), and the difference in height between the installation positions of the appliance body (A) and the bathtub (2). Can be properly filled with water even if the amount of water does not vary depending on the installation equipment.

However, in the above-mentioned conventional apparatus, the performance of the water pressure gauge (34) changes with the passage of a long time, so that the water level in the bathtub when the filling is completed is gradually deviated from the proper water level. There was an inconvenience. The present invention has been made in view of the above-mentioned points, and includes "a water filling circuit (17) for supplying hot water to the bathtub (2) and the water filling circuit (17).
The water filling valve (4) and the water pressure gauge (34) inserted in the bath, and the operation switch (3) operated when filling the bathtub (2) with water.
2), the water pressure gauge (3) in a state where the water filling circuit (17) on the downstream side of the water pressure gauge (34) is filled with water.
In the bath device adapted to determine the water level filled in the bathtub (2) based on the reference water pressure (P0) detected by 4) and the water pressure detected by the water pressure gauge (34) during actual water filling.
Even if the performance of the water pressure gauge (34) changes with time, the problem is to prevent the water level in the bathtub from greatly deviating from the proper water level after the completion of the water filling.

[0007]

The technical means of the present invention for solving the above-mentioned problem is "a water filling counter for counting the number of times the operation switch (32) is turned on, and the counted value is monitored to reach a predetermined value. At the time, a judging device for outputting an initial setting request signal is provided, and when the judging device outputs an initial setting request signal, an initial setting operation for redetermining the reference water pressure (P0) is executed, and
I tried to reset the water filling counter. ”

[0008]

The above technical means operates as follows. When the operation switch is turned on, the filling operation of supplying hot water to the set water level to the bathtub is executed in the same manner as the conventional one, and the number of times the operation switch is turned on is counted by the water filling counter and the counted value is obtained. Will increase. That is, the number of times of water filling is counted by the water filling counter.

When the above-mentioned filling operation is repeated and the above-mentioned count value output from the counter for the number of filling times reaches a predetermined value, the judging device for monitoring the count value outputs an initial setting request signal. When the signal is generated, the initialization operation for determining the reference water pressure (P0) is executed in the same manner as the conventional one described above.

When the initial setting request signal is issued, the water filling counter is reset to zero. As a result, when the subsequent operation switch (32) is turned on, the number of times the switch is turned on is counted again from the beginning. In this way, when the water filling operation is repeated a predetermined number of times, the initial setting operation for redetermining the reference water pressure (P0) by the water pressure gauge (34) is executed each time.

[0011]

[Effect] The present invention has the following specific effects. Since the reference water pressure (P0) is checked by the water pressure gauge (34) every time the filling operation is repeated a predetermined number of times, even if the performance of the water pressure gauge (34) changes with time, the reference water pressure (P0) can be changed accordingly. P0)
Since the value of is determined, it is possible to prevent the inconvenience that the water level in the bathtub at the time of actual filling is largely deviated from the appropriate water level.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the embodiments of the present invention described above will be explained with reference to the drawings. The water circuit and the like of the bath apparatus according to the embodiment of the present invention is configured similarly to that of FIG. 1 described above. Control device (3) for controlling the operation of the water filling valve (4) and the water heater (5)
A control program having the content shown in the flowchart of FIG. 2 is written in the microcomputer of FIG. 2. Next, the operation of the bath apparatus according to the embodiment of the present invention will be described with reference to FIG. . First, when the power switch (31) is turned on, the water filling frequency memory N for counting the number of water filling operations described later is set to "0" (see steps (61) and (62) in the drawing).

.. Next, the hot water filling valve (4) is opened to supply water to the bathtub (2) and the water supply state is continued for a certain period of time (see steps (63) and (64) in the drawing). In addition, the above-mentioned certain time for maintaining the water supply state is necessary for the water from the water heater (5) supplied through the water filling valve (4) to reach the water outlet (29) of the water filling circuit (17). It is set to a different time. Therefore, when the water filling valve (4) is closed when the time has elapsed (see the step in the drawing (65)), the water supplied from the water heater (5) reaches the spout (29). It will be. Therefore,
When the water filling valve (4) is closed in this state, water is contained in the water filling circuit (17) from the water filling valve (4) to the water discharge port (29).

.. When the water filling valve (4) is closed, the water pressure detected by the water pressure gauge (34) is then determined.
As described above, water is contained in the flow path from the outlet to the outlet (29) at the downstream end of the water filling circuit (17). Therefore, the water pressure detected by the water pressure gauge (34) at this time is detected. Is equal to the reference water pressure (P0) that is detected by the water pressure gauge (34) on the platform that is assumed to be filled with water up to the spout (29) of the bathtub (2). Then, the reference water pressure (P0) is stored in the memory of the microcomputer of the control device (3) (refer to step (66) in the drawing).

[0015] Next, the value of the water filling frequency memory N set to “0” at the time of turning on the power described above is checked, and it is
If it is not "0", it waits until the operation switch (32) is turned on (see the steps of the drawing code blocks (67), (68)).

.. When the operation switch (32) is turned on, the water filling frequency memory N for storing the number of times of the water filling operation.
If the value of the water filling frequency memory N is not "50" after increasing the value of "1", that is, if the water filling operation is not performed 50 times, the water heater ( 5) is brought into an operating state, hot water is boiled by this, and the water filling valve (4) is opened to start the water filling operation to the bathtub (2) (see steps (70) to (72) in the drawing). still,
In this embodiment, the functional unit in the control device (3), which increases the value of the filling frequency memory N every time the operation switch (32) is turned on, has a function part described in the technical means section. Corresponds to a counter.

[0017] When the filling operation starts, the water pressure gauge (3
The filling operation is advanced while judging the detected water pressure of 4), and the detected water pressure of the water pressure gauge (34) is the reference water pressure (P
Corresponding to the height difference between the water level and the spout (29) when it is assumed that the water level in the bathtub (2) has risen to a set water level (K) suitable for bathing, which is higher than 0) by a certain water level. When the water pressure gauge (34) detects a pressure greater than the reference water pressure (P0) by the water head pressure ΔP, the water heater (5) is stopped and the water filling valve (4) is closed to end the water filling operation (drawing). See steps (73) and (74). And
After that, the control operation is returned to the step of the above-mentioned drawing code (68) for monitoring the closing of the operation switch (32).

.. When it is determined in the step of the drawing symbol (70) that the value of the water filling frequency memory N, which stores the number of times the operation switch (32) has been turned on, is reached "50", the hot water filling operation is repeated. The above-mentioned drawing code (63) for checking the reference water pressure (P0) by opening the tension valve (4) for a certain period of time
Even if the control operation of (66) is executed and the performance of the water pressure gauge (34) is changed compared to when the equipment was initially installed, the reference water pressure (P0) is checked again by the water pressure gauge (34) at that time. , This value is stored again in the memory of the microcomputer. Then, after resetting the value of the number N of times of filling water to "0", the water filling operation is performed in which the water heater (5) is put into the operating state and the filling valve (4) is opened. In this embodiment, the functional unit in the control device (3) for judging whether or not the value of the above-mentioned filling frequency memory N has become "50" is the judging device described in the above-mentioned technical means section. It corresponds.

As described above, according to the above-described embodiment, the reference water pressure (P0) is re-measured every time the filling operation is repeated a certain number of times, so that the performance of the water pressure gauge (34) changes with a long time change. Even if it comes, the standard water pressure (P
0) is determined, and there is less inconvenience that the water level in the bathtub (2) is greatly deviated from the proper water level when the filling of water is completed.
When the operation switch (32) is turned on while the bathtub (2) is already filled with water, the bathtub (2) may be heated to a set temperature suitable for bathing. If the water level in the bathtub (2) is slightly insufficient when the operation switch (32) is turned on,
You may make it perform the operation which replenishes this with warm water. That is, the operation switch (3) has a function as a so-called automatic switch for executing the appliance operation according to the state in the bathtub (2).
It may be added to 2).
