Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a bath water purifying apparatus.

[0002]

2. Description of the Related Art Bath water purifying apparatuses for circulating and purifying bath water in bathtubs have become widespread in recent years. As shown in FIG. 11, a circulating pump P is provided inside the bath water purifying apparatus. The circulating pump P is used to supply bath water from a bath tub B to perform predetermined processing such as filtration, sterilization or heating. In addition, the water flows into the bathtub B. In such a bath water purification device, it is necessary to drain water from the inside of the device and the piping when cleaning and maintaining the inside of the device. There was a problem that it took time and effort to fill the water.

[0003]

In order to solve this drawback, a self-contained pump may be used as the circulating pump. However, the self-contained pump is expensive and has a high closing pressure due to its structure. In addition, there is a problem that the pressure resistance of the pipes and pipes must be increased, which further increases the cost and limits the improvement of the self-sufficiency performance. Further, performing the self-sufficiency operation for a longer time causes a problem such as shortening of the pump life. An object of the present invention is to remedy the disadvantages of the prior art.

[0004]

In order to achieve the above-mentioned object, the present invention provides a bath, wherein after entering bath water from a bath tub and performing a predetermined purification treatment, the purified bath water flows out of the bath tub. In the water purification apparatus, a non-self-contained pump for circulating the bath water, a self-contained pump disposed in parallel or in series with the non-self-contained pump, and A control device for performing a water filling operation using the self-contained pump at a time, and switching to operation of the non-self-contained pump when the water filling state is confirmed. According to the above configuration, the self-contained pump allows water to be filled in the apparatus and the piping without manual operation. Further, since the self-contained pump is used only at the time of filling with water, a small capacity pump may be used. Therefore, it is not necessary to increase the pressure resistance of the apparatus itself or the piping, and the cost increase is reduced. It is also possible to improve the self-sufficiency performance and extend the life of the pump. It is also possible to provide a sensor for detecting whether or not there is water in the device, and to configure the control device to recognize a water filling state based on a signal from the sensor. Further, it is possible to further provide a means for giving a reference time required for filling with the self-contained pump, and the control device can recognize the filling state based on the reference time from the means for giving the reference time.
When the operation is started by operating the operation start key or the like, the water filling operation is performed using the self-contained pump, and when the state of the water filling is confirmed, the operation is switched to the non-self-contained pump to perform the normal operation. Such a configuration is also possible. In the case of this configuration, the water filling operation is always performed automatically at the start of the operation, so that an accident caused by forgetting to fill the water can be prevented.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, a water inlet pipe 1 is connected to a bathtub B, and the bathwater in the bathtub B is sucked by a non-self-contained pump P1 through the water inlet pipe 1, sent to a filtration tank T, and heated to a predetermined temperature by a heater H. It is configured to heat and return the bath water to the bathtub B via the water discharge pipe 2. A check valve V1 is provided on the bathtub B side of the non-self-contained pump P1 to prevent backflow of the bath water.

[0006] A parallel pipe 3 is provided at both ends of the non-self-contained pump P1.
The self-contained pump P2 and the check valve V2 are interposed in the middle of the parallel piping 3. Self-contained pump P
Numeral 2 is used for filling the inside of the apparatus and each pipeline with water. Normally, only the non-self-contained pump P1 is used as shown in FIG. During normal operation, the bath water is supplied to the inlet pipe 1
Through the check valve V1 and the non-self-contained pump P1 to the filtration tank T, and from the heater H to the bathtub B through the water discharge pipe 2.

FIG. 2 shows the flow of bath water at the time of water filling. The non-self-contained pump P1 stops driving, only the self-contained pump P2 operates, and the bath water flows from the water inlet pipe 1 to the check valve V2. It is configured to return from the water discharge pipe 2 to the bathtub B via the self-contained pump P2, the filtration tank T and the heater H. The check valve V1 allows the self-contained pump P2 and the non-self-contained pump P1 to smoothly fill with water without circulating the bath water.

As described above, since the water filling is performed by the self-contained pump P2, the labor of water filling as in the conventional case is reduced. Further, since the self-contained pump P2 is used only at the time of filling with water, its capacity may be smaller than that of the non-self-contained pump P1, and it is sufficient if the capacity is sufficient to fill the water. In addition, the self-contained pump P2 is driven only when it is filled with water, and has a small capacity. Therefore, it is not necessary to increase the pressure resistance of the filtration tank T and each pipe in the apparatus.

A control device 5 for controlling the entire device such as the non-self-contained pump P1, the self-contained pump P2 or the heater H, and an operation device 6 for a user to operate are provided. When the user issues a water filling command or an operation start command via the operation device 6, the control device 5 starts the self-contained pump P2.
Is driven to perform water filling, and when the water filling is completed, the self-contained pump P2 is stopped, and the drive is switched to the non-self-contained pump P1 to perform normal operation. Various methods can be adopted as means for detecting the completion of water filling. For example, a water presence / absence sensor is provided in the pipeline of the apparatus, the filtration tank T, or the like, and the completion of water filling is detected by a detection signal from the sensor. Configurations can be employed. Alternatively, timer means may be provided in the control device 5 so that the water filling time is counted, and when a predetermined time has elapsed, it is determined that the water filling is completed. In this case, the predetermined time may be a predetermined time, or it may be configured that actual filling is performed and the time required at that time is stored in a memory or the like.

FIGS. 3 and 4 show another embodiment, in which a check valve V1 is provided on the water inlet pipe 1 side of the non-self-contained pump P1.
Is provided with a series pipe 4 in parallel with the self-contained pump P2.
And a non-self-contained pump P1 and a self-contained pump P2 are connected in series. FIG. 4 shows the flow of bath water at the time of water filling. Other configurations are the same as those in the embodiment shown in FIG.

FIGS. 5 and 6 show another embodiment in which a check valve V1 is provided on the filtration tank T side of the non-self-contained pump P1.
, A series pipe 4 is provided in parallel with this, and a self-contained pump P2 is interposed here. FIG. 6 shows the flow of bath water at the time of water filling. Other configurations are the same as those in the embodiment shown in FIG.

The operation will be described with reference to FIGS. Here, a water filling timer and a memory for storing the water filling time are provided, the water filling is actually performed, a necessary reference time is determined, and thereafter, the water filling operation is performed based on the reference time. The control device 5 checks whether or not the water filling key of the operating device 6 has been pressed (step S1). When the water filling key is pressed, the timer starts counting (step S2), and at the same time, starts the operation of the self-contained pump P2. (Step S3). When the operator confirms the end of the water filling (step S4) and presses the water filling key again (step S5),
The control device 5 stops the self-contained pump P2 (step S5).
6) The time measured by the timer is stored in the memory (step S7).

In FIG. 8, when the operation key is pressed (step S8), the stored water filling time is read from the memory (step S9), and at the same time, the operation of the self-contained pump P2 is started (step S10), and the timer is started. Then, the counting of the operation time is started (step S11). When the running time reaches the stored water filling time (step S12),
The self-contained pump P2 is stopped (Step S13), the operation of the non-self-contained pump P1 is started (Step S14), and the normal operation state is set.

The operation when the water presence / absence sensor is used will be described with reference to FIG. When the operation key is pressed (step S15), the operation of the self-contained pump P2 is started (step S16), and when a water-present state is detected by the sensor (step S17), the self-contained pump P2 is stopped (step S18). ), The operation of the non-self-contained pump P1 is started (step S19), and the normal operation is performed.

According to the configuration of the embodiment described above, water filling can be performed by the self-contained pump P2, and the burden on the user can be reduced. Further, since the water filling operation is automatically performed at the start of the operation, there is no danger of forgetting to fill the water. Further, since the self-contained pump P2 can be small in size, and it is not necessary to increase the pressure resistance of the entire apparatus, there is an effect that an increase in cost can be suppressed.

In the above-described embodiment, the non-self-contained pump P1 is provided with a flow rate adjusting function to suppress the variation of the circulating flow rate of the bath water generated due to the installation state of the apparatus, and to exhibit the appropriate purifying function. Can be maintained. FIG. 10 shows this operation. During normal operation (step S30), the flow rate adjustment function is selected (step S3).
1) A flow adjustment operation is performed (step S32). When the operation is completed (step S33), the adjustment state is stored (step S34), and normal operation is performed in this state.
