[Industrial application fields]
The present invention relates to a bath apparatus that automates an optimal bathing environment by using both reheating and hot water purification.
[0002]
[Prior art]
Conventionally, a bath apparatus is provided with a memory circuit that tracks hot water in a bathtub. As is well known, the memorial circuit detects the water level and temperature of the hot water in the bathtub, heats it based on the hot water information, and supplies hot water from the water supply side. And the level of the hot water in the bathtub is generally detected by a pressure sensor through a return pipe.
[0003]
In addition, a purification circuit is attached to the bath apparatus in order to remove dirt from the hot water in the bathtub. The purification circuit circulates and purifies hot water in the bathtub through a filter and returns the hot water to the bathtub.
[0004]
[Problems to be solved by the invention]
By the way, the memorial circuit and the purification circuit both perform hot water circulation by a circulation pump. The chasing operation is a control for causing the hot water in the bathtub to reach a desired water amount and temperature, and it is necessary to accurately detect the water level in the bathtub. In the water level sensor using the pressure sensor, the chasing operation is performed. The pulsation of hot water in the dredging circuit decreases the detection accuracy. In other words, the circulation of hot water by the purification circuit may reduce the accuracy of detecting the water level in the tracking circuit and reduce the reliability of the tracking operation. Therefore, the chasing operation and the purifying operation cannot be used together.
[0005]
However, selectively performing the memorial operation and the purification operation is inefficient, and when the purification time is limited to a short time, discomfort to the bather is ignored depending on the purification ability with respect to the amount of hot water in the bathtub. I can't.
[0006]
In addition, it is possible to form the circulation port by making the memorial circuit and the purification circuit independent so as to prevent the interference between the two, but the circulation circuit becomes complicated and a plurality of openings are formed in the bathtub. There is a disadvantage of having to.
[0007]
Therefore, the present invention prevents the mutual interference between the pursuit circuit and the purification circuit, and can perform the pursuit and the hot water purification simultaneously or selectively, thereby accelerating the realization of a clean and optimum environment for bathing. An object is to provide a bath apparatus.

[0029]
Next, FIG. 6 has shown one Example of the control apparatus of the bath apparatus of this invention. This control device includes a main water supply unit 140 and a hot water supply / remembrance control unit 142 that performs hot water supply and reheating, and a purification control unit 144 that performs purification control. The main control unit 140 controls the control units 142 and 144. Each control unit 140, 142, 144 can be configured with a microcomputer, but can also be configured with an analog circuit. In realizing the necessary control operation, the control device may take any form.
[0030]
The hot water supply / remembrance control unit 142 performs each control of hot water supply or renewal, and includes various instructions such as operation instructions relating to operations such as hot water supply, replenishment of hot water, hot water circulation, burner combustion, and set temperature. Is input, and the detected temperatures of the temperature sensors 32 and 44 of the tracking circuit 10 and the hot water supply circuit 8 and the detected water level of the water level sensor 42 are input. Based on these input data, the circulation pump 40, the fuel on-off valve 52, the fuel proportionality A drive command is issued to the valve 30, various switching valves, and on-off valves. Then, the control unit 144 controls the operation of the purification circuit 12. The purification control unit 144 receives an operation instruction such as a purification operation and a temperature detected by the temperature sensor 56. Based on these input instructions, the circulation pump 54 and the sterilizer 70 blink, the switching valve 60, 66 is switched.
[0031]
The main control unit 140 receives an instruction for commanding the operation of each of the hot water supply circuit 8, the memory circuit 10, the purification circuit 12, or both. In addition, a temperature setting and a water level setting necessary for hot water supply / reheating operation are input. Temperature and water level setting data is transmitted to the hot water supply / remembrance control unit 142 via the main control unit 140, and operation instructions are issued to the hot water supply / remembrance control unit 142 and the purification control unit 144.
[0032]
Further, the temperature detected by the temperature sensor 56 of the purification circuit 12 is transmitted to the hot water supply / remembrance control unit 142 via the main control unit 140, and the hot water supply / remembrance control unit 142 is based on a signal from the purification control unit 144. Start the memorial operation.
[0033]
In the above configuration, the operation of the bath apparatus will be described.
[0034]
FIG. 7 shows the purifying operation by the purifying circuit 12 and the pursuit operation by the memorial circuit 10. The purifying circuit 12 drives the circulation pump 54 according to the command of the purifying control unit 144 and operates the sterilizer 70, that is, sterilizes the hot water 4 by turning on the sterilizing lamp, and filters dirt and the like by the filter 62, Remove dirt from hot water 4.
[0035]
When the temperature of the hot water 4 circulating through the purification circuit 12 is detected by the temperature sensor 56 and it is determined that the detected temperature is lower than the set temperature, the determination result is sent from the purification control unit 144 to the main control unit 140 and the hot water supply / This is transmitted to the tracking control unit 142. The hot water supply / remembrance control unit 142 receives this temperature data, drives the circulation pump 40, and checks the flowing water by the flowing water switch 46, opens the fuel on-off valve 52 and starts combustion of the burner 50.
[0036]
Since the hot water 4 in the bathtub 2 is agitated during purification, the temperature detection of the hot water 4 in the purification circuit 12 is accurately performed. When the detected temperature falls below the set temperature by a predetermined temperature, the remedy circuit 10 starts the remedy and heats the hot water 4 in the bathtub 2 based on the temperature data. The temperature of hot water can be effectively maintained using the combustion capability of the soot circuit 10.
[0037]
Now, when chasing, the hot water 4 heated by the heat exchanger 48 is discharged into the bathtub 10 from the discharge port 6A of the circulation connection device 6 via the forward pipe 16, and the heated hot water is joined to the junction 72. In this case, the amount of heat is relieved because it merges with the circulating water from the purification circuit 12. As a result, the temperature of the discharged hot water from the discharge port 6 </ b> A becomes lower than the hot water temperature of the heat exchanger 48. In this case, in the circulation connecting device 6, the discharge port 6A is formed at the center, but the temperature of the discharged water becomes a comfortable temperature due to the merging with the hot water on the purification circuit 12 side, and the body by the discharged water Can be moderately stimulated. Moreover, air bubbles can be mixed in the discharged water by mixing air generated from the air generation source 74, and the body can also be stimulated by these bubbles.
[0038]
The hot water supply / remembrance control unit 142 compares the detected value from the temperature sensor 44 with the set temperature, and when the detected value from the temperature sensor 44 reaches the set temperature, the fuel on-off valve 52 is closed and the burner 50 burns. Is stopped, the circulation pump 40 is stopped, and the chasing operation is finished.
[0039]
Next, FIG. 8 shows supply of hot water by the hot water supply circuit 8 and purification operation of the purification circuit 12. The operation of the purification circuit 12 is as described above. The water level of the bathtub 2 detected from the water level sensor 42 of the memorial circuit 10 is determined based on the hydrostatic pressure detected via the return pipe 18 from the suction port 6B of the circulation connecting device 6.
[0040]
The suction port 6B and the suction port 6C in the circulation connecting device 6 are set so that the water flows are separated from each other by the rectifying cover 118, the passage separation pipe 104, and the fixed flange 106, so that the suction from the suction port 6C. The flowing water does not suck the hot water 4 in the return pipe 18 on the suction port 6B side. Therefore, there is no influence on the water level detection of the water level sensor 42, and accurate water level detection can be performed. And the purification circuit 12 can detect the water level in the bathtub 2 even during the purification of the hot water 4, and the required amount of hot water 4 can be accurately supplied to the bathtub 2 based on the detection. In short, according to this circulation connecting device 6, even when the pursuit circuit 10 is chased, the rectifying cover 118, the passage separation pipe 104, the fixed flange 106 and the like are shielded between the passages even if the suction operation of the purification circuit 12 is used together. As a means, water level control can be performed based on accurate water level detection without causing sneaking or pulsation of suction water.
[0041]
Then, the detection value of the water level sensor 42 is compared with the set water level, and when the water level is lowered by a predetermined level from the set water level, hot water supply is started from the hot water supply circuit 8 to the bathtub 2 side to replenish the insufficient water amount. That is, when the amount of water in the bathtub 2 is insufficient, the on-off valve 34 is opened, the fuel proportional valve 30 is opened, the burner 28 is ignited, and combustion is started. The heated hot water is supplied to the bathtub 2 from the forward pipe 16 through the hopper 36 and the switching valve 38. When the detection value from the water level sensor 42 reaches the set water level, the on-off valve 34 and the fuel proportional valve 30 are closed to stop hot water supply. The temperature sensor 32 detects the hot water temperature on the heat exchanger 26 side, and adjusts the hot water temperature based on this detected temperature.
[0042]
Next, FIG. 9 shows a cleaning operation (back cleaning operation) of the filter 62 of the purification circuit 12. In the filter 62, unclean substances accumulate inside due to purification of the hot water 4, and as a result, the purification capacity of the hot water 4 decreases. Therefore, it is necessary to periodically pass hot water from the reverse side of the filter 62 and dispose of uncleaned substances outside. The filter 62 is cleaned every predetermined time.
[0043]
When the purification control unit 144 detects that a predetermined time has elapsed after the flowing water switch 58 detects flowing water after the purification operation is started, the switching valve 60 is switched to the flow path from the filter 62 to the discharge pipe 68. Is switched to the flow path from the bypass path 64 to the filter 62, and a cleaning command is issued to the hot water supply / remembrance control section 142 via the main control section 140. The purification control unit 144 drives the circulation pump 54 to suck in the hot water 4 in the bathtub 2 from the suction port 6 </ b> C, and causes the filtered water 62 to flow in the reverse direction via the bypass path 64. The hot water 4 that has passed through is discharged from the drain pipe 68 to the outside. As a result, the filter 62 is cleaned.
[0044]
At this time, the hot water supply / remembrance control unit 142 replenishes the bathtub 2 with the hot water 4 based on the cleaning instruction of the filter 62. This is because the hot water 4 in the bathtub 2 is used to wash the filter 62 and the hot water 4 is discharged to the outside, so that the hot water in the bathtub 2 is reduced. 4 is replenished. Since the hot water 4 in the bathtub 2 is replenished with the discharge, the water level in the bathtub 2 can be maintained without being extremely reduced.
[0045]
【The invention's effect】
As described above, according to the present invention, the following effects can be obtained.
a. The remedy circuit and the purification circuit can be connected to the bathtub with a single circulation connection means to perform selective operation, chasing operation or hot water purification of both, and the water flow of both on the circulation connection means side of the bathtub. Therefore, it is possible to suppress a decrease in detection accuracy of the water level due to pulsation that has conventionally occurred during the purification operation, and it is possible to simultaneously perform the pursuit operation and the purification operation. For this reason, chasing and hot water purification can be performed simultaneously or selectively, and the realization of a clean and optimum environment for bathing can be speeded up.
b. Compared to the conventional control that was forced to selectively perform the pursuit operation and the purification operation during bathing, it can be used together with the pursuit and hot water purification. Can be cleaned.
