Abstract

PURPOSE:To perform foam bath operation for a long time without lowering the temperature of bath tub by a method wherein a title device is provided with a temperature sensor to detect a bath tub temperature and a regulating valve to regulate a quantity of water passing a position on the bath burner side, and even during foam bath operation, a part of circulating water is distributed and caused to flow to a position on the bath burner side according to a bath tub temperature. CONSTITUTION:When a bath tub temperature is decreased during foam bath operation, the decrease of the bath tub temperature is detected by a temperature sensor 7. When the bath tub temperature is decreased to a value lower than a specified value, the opening of a regulating valve 9 is increased through a control part 20, and a quantity of water flowing to the heat exchange coil 3a side is increased. This operation properly heats circulating water and the circulating water is returned to a bath tub 1 and therefore, a bath tub temperature is increased. When the bath tub temperature is increased to a value higher than a specified value, the opening of the regulating valve 9 is decreased. Namely, by properly regulating a quantity of circulating water distributed to the bath burner 2 side, the decrease of the temperature of bath tub water during foam bath operation is prevented, and heat insulation is effected. Regulation of a water quantity by means of the regulating valve 9 may be effected in two kinds of high and low, and regulation in multistage or non-stage regulation containing complete closing may be effected.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a bath device having a bubble bath function.

<Prior art and its problems> In this type of conventional bath device with bubble bath function,
The bubble bath operation and the bath reheating operation were not designed to operate at the same time. One of the major reasons for this is that bubble bath operation requires a large circulation flow rate and flow rate of bath water to mix air, and for this purpose, the bath water must be circulated through a reheating circulation path. This is because the flow rate and flow velocity cannot be obtained. This is because the circulation path for reheating must pass through a heat exchange coil in the bathtub, and a large flow rate and velocity cannot be expected. Therefore, conventionally, the reheating operation was stopped while the bubble bath operation was performed.

However, this conventional configuration has the disadvantage that when the bubble bath is operated for a long time, the temperature of the bathtub decreases due to air intrusion and the like.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a bathing device with a bubble bath function that eliminates the drawbacks of the above-mentioned prior art and does not cause the temperature of the bathtub to drop even if the bubble bath is operated for a long time.

Means for Solving the Problems> In order to achieve the above object, the bath device with a bubble bath function of the present invention is provided with a reheating function that guides the bathtub water to the bath pot and reheats it, and also has A bathing device with a bubble bath function, which has at least a bubble bath function of short-circuiting bathtub water by providing a short-circuit path in the middle, introducing air while spouting bubble-mixed water into the bathtub, and detecting the temperature of the bathtub. It has a temperature sensor and a control valve that adjusts the amount of water passing through the bathtub side, and is configured to distribute and flow a part of the circulating water to the bathtub side according to the bathtub temperature even during bubble bath operation. It is a feature.

<Operation> During bubble bath operation, when the bathtub temperature measured by the temperature sensor decreases, the control valve opens wider and the flow rate to the bathtub increases. When the bathtub temperature rises to, for example, a set temperature, the control valve is closed or throttled to reduce the bathtub temperature by making the flow rate to the bathtub zero or more than zero, which is considered to be extremely small. It is possible to perform a bubble bath operation for a long time without any trouble.

<Example> FIG. 1 is a block diagram of an apparatus implementing the present invention, and FIG. 2 is a time chart during bubble bath operation.

A circulation path 3 is provided from a bathtub 1 to a bath pot 2, and a circulation pump 4 is provided in the middle. A short circuit path 5 is provided in the circulation path 3, and an orifice 6 is provided in the middle of the short circuit path 5 to increase the flow velocity. Further, a temperature sensor 7 for detecting the temperature of the bathtub, a water flow switch 8, and a control valve 9 for regulating the amount of water passing through the bathtub 2 are provided on the side of the bathtub 2 from the short-circuit path 5 of the circulation path 3. A heat exchange coil 3a from the circulation path 3 is installed in the bathtub 2.
is arranged so that the water passing through the coil 3a is heated by the bath pot 2. Further, an inlet pipe 2a and an outlet pipe 2b for supplying hot water are provided, and a burner 2c is provided. On the other hand, a connection fitting 10 is provided at the connection part between the bathtub 1 and the circulation path 3, and an air introduction pipe 11 and its on-off valve 1 are provided.
2 is provided. The air introduction pipe 11 is connected, for example, to a negative pressure forming part of an ejector provided near the outlet of the circulation path 3 into the bathtub 1.

A control unit 20 controls the operation of the circulation pump 4, the on-off valve 12, the control valve 9, the burner 2c, etc. based on commands from the remote controller 30 and input information from the temperature sensor 7, water flow switch 8, etc.

Now, when reheating operation is performed, the circulation pump 4 is turned on, the control valve 9 is set to a sufficiently large opening degree, and the opening/closing valve 1 is set to a sufficiently large opening degree.
2 is closed, and by turning on the water flow switch 8, the burner 2 is turned on.
The operation of step c is also started, and the bath water is circulated to the bath pot 2.
It is heated by the heat exchange coil 3a.

On the other hand, when a bubble bath operation is performed, the circulation pump 4 is started in response to a command from the remote controller 30, and the control valve 9 is sufficiently throttled to reduce the flow rate through the heat exchange coil 3a. . Also, the on-off valve 12 is opened. Further, the water flow switch 8 is activated, the burner 2c is ignited, and the bath pot 2 is maintained at a predetermined temperature. Most of the circulating water from the bathtub 1 passes through the short circuit 5, increases the flow velocity at the orifice, is circulated to the bathtub 1, and is ejected from the connecting fitting 10.

Then, air from the air introduction pipe 11 is mixed in at the connection fitting 10, and the water is spouted into the bathtub 1 as foam-mixed water.

During bubble bath operation, when the bathtub temperature drops, it is detected by the temperature sensor 7, and when the temperature falls below a certain level, the opening degree of the control valve 9 is increased via the control unit 20, and the temperature is increased to the heat exchange coil 3a side. The amount of water flowing is increased. This will heat the circulating water appropriately and return it to the bathtub l.
The bathtub temperature increases. When the bathtub temperature rises above a certain level, the opening degree of the control valve 9 is reduced again. That is, during the bubble bath operation, by appropriately increasing or decreasing the amount of circulating water distributed to the bathtub 2 side, the temperature of the bath water is prevented from decreasing during the bubble bath operation, and the temperature is maintained. The amount of water can be adjusted in two ways, large and small, or can be adjusted in multiple stages or steplessly, including complete closure. Such configurations are also within the scope of the present invention.

<Effects> The present invention has the above configuration, and according to the bath device with a bubble bath function according to claim 1, even during the bubble bath operation, a part of the circulating water is distributed to the bathtub side according to the bathtub temperature. Since the bathtub water is flushed, the bathtub water can be appropriately heated even during the bubble bath operation, and the problem of the bathtub temperature decreasing during the bubble bath operation can therefore be solved.
