Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention sets the temperature and level of hot water in a bathtub in advance to desired values, and then temporarily raises or lowers the hot water temperature according to the individual bather's request. Or, it relates to an automatic bath device having a function of temporarily increasing the water level.

[0002]

2. Description of the Related Art In a conventional automatic bath device, when the temperature and water level of hot water in a bathtub are set to desired values in advance,
(Hereinafter, these set temperature and water level are referred to as set temperature Ts and set water level Ls, respectively), when the set temperature Ts and set water level Ls are automatically filled with water, and when the hot water temperature drops thereafter. Is heated up to the set temperature Ts, and when the water level drops due to the use of hot water, so-called automatic hot water filling / warming hot water is poured until the set water level Ls is reached (hereinafter referred to as "additional water"). Those having functions are provided.

However, with the automatic bath apparatus having such a function, the temperature and the water level of the hot water in the bathtub are set to the set temperature T.
Even if the set water level Ls is automatically maintained, it may happen that the individual bather wants to temporarily change the temperature Ts and the water level Ls.

[0006] For example, as for the bath temperature, there are individual differences in the sensation of the bather, so hot water at the set temperature Ts is hot, and the bath temperature is higher than the set temperature Ts only when the bather is bathing. You may want to lower it too. On the other hand, even for the same bather, if the body gets used to the bath temperature after bathing, it may feel lukewarm as it is.
There may be a case where the hot water temperature is desired to be higher than the set temperature Ts.

Regarding the water level, it may be desired to pour a certain amount of hot water (hereinafter referred to as "bath water") beyond the set water level Ls in order to feel a relaxing bathing feeling.

Therefore, in order to meet the demands of such individual bathers, in the prior art, an operation switch for increasing the hot water temperature by a constant width ΔT from the set temperature Ts (hereinafter, referred to as
A hot switch), an operation switch for decreasing the hot water temperature by a constant width ΔT below the set temperature Ts (hereinafter referred to as a lukewarm switch), and a hot water supply for increasing the set water level Ls by pouring a fixed amount of water. There is also provided a device provided with an operation switch (hereinafter, referred to as plenty of switches).

That is, in the apparatus of this configuration, when the hot switch is operated, for example, only once, the temperature T to be the control target (hereinafter referred to as the target temperature) T is set to the set temperature Ts.
T = Ts + ΔT so as to be increased by a constant width ΔT (for example, 1 ° C.), and reheating is performed so that the hot water temperature rises to the target temperature T. Therefore, a bathing feeling "hot" by ΔT above the set temperature Ts can be obtained.

When the lukewarm switch is operated only once, for example, T = T so that the target temperature T becomes smaller than the set temperature Ts by a constant width ΔT (for example, 1 ° C.).
Let s-ΔT, and pour water to the target temperature T so that the hot water temperature drops. For this reason, a "slimy" bathing feeling can be obtained by ΔT above the set temperature Ts.

Furthermore, when the full switch is operated, a fixed amount (for example, 20 liters) of hot water is supplied, so the water level rises by ΔL above the set water level Ls, and a "full bathing" feeling is obtained. .

By the way, when the hot switch or the lukewarm switch is operated, for example, only once, the target temperature is changed to T = Ts ± ΔT, but the changed state of the target temperature is changed by the next bather. If it is continued for a long time as it is, the next bather will have an inconvenience that the hot water temperature will be too hot or too slim and will cause discomfort.

Therefore, it is desirable to temporarily change the target temperature T by using such a hot switch or a lukewarm switch.

Therefore, in the prior art, the switch that is hot,
Alternatively, when the lukewarm switch is operated to change the target temperature T, the target temperature T is returned to the set temperature Ts and T = T after the predetermined time t ₀ set in advance has elapsed from the time of operating the switch. Ts, and thereafter, this set temperature Ts
Insulation combustion control is performed so that the hot water temperature is maintained.

[0013]

However, the following problems still remain in such a conventional automatic bath device.

(1) As described above, the time from the change of the target temperature T by the operation of the hot switch or the lukewarm switch to the return to the original set temperature Ts (hereinafter referred to as the holding time) t ₀ is conventionally It is fixed (for example, 15 minutes).

Therefore, when the person who operates the hot switch or the lukewarm switch continues to bathe for the holding time t ₀ or longer, the hot water temperature is set to the set temperature Ts during bathing.
And the person will not be able to enjoy the desired bathing feeling.

On the other hand, when the next person takes a bath before the holding time t ₀ elapses, the hot water does not reach the preset set temperature Ts, so that it is too hot or too luke. As a result, it is not possible to enjoy a comfortable bath, and the provision of a hot switch or a lukewarm switch is rather an adverse effect.

(2) Further, as described above, when the plenty of switches are operated, the set water level Ls is exceeded and Δ
L (In the above example, the water level rises with 20 liters of hot water)
When the hot water is poured so that the water level rises, and when the water level in the bathtub drops due to the use of hot water, the original set water level L
Although the hot water is added so as to return to s, in the conventional technique, the target temperature T when the hot water or the hot water is added is
Are controlled to match the set temperature Ts.

Therefore, even if the hot or lukewarm switch is operated to change the hot water temperature, the holding time t ₀
If, for example, the switch is fully operated before the lapse of time, hot and cold water of the set temperature Ts will be poured, and even though it is hot, it becomes lukewarm.
On the other hand, even if it becomes dull and hot, in this case as well, the person cannot enjoy the desired bathing feeling.

The present invention has been made in order to solve the above-mentioned problems, and the feeling of bathing "hot" or "warm" above the set temperature does not affect others, and the bathing time is long or short. Or, the challenge is to be able to continue to enjoy the taste of the person as desired, without being affected by the presence or absence of footbath or hot water.

The bathing detection means in the claims corresponds to the water level sensor 10 described above.

Further, the hot water supply channel 1 is provided at an intermediate position of the circulation channel 4 upstream of the circulation pump 8 to reach the water level sensor 10.
5, a check valve 16, an opening / closing valve 17, a water heater 18, and a temperature sensor 19 for detecting the incoming water temperature are sequentially connected to the hot water supply water passage 15 toward the upstream side.

Furthermore, the automatic bath apparatus 1 of this embodiment is
The remote control device 20 and the controller 22 are provided.

The remote controller 20 is for inputting various commands to the controller 22, and in this example, a temperature setting switch 31 for determining the set temperature Ts and a set water level Ls are set on the operation panel. Water level setting switch 32, an automatic operation switch 33 for specifying the automatic hot water filling / warming hot water function mode, and the hot water temperature setting temperature Ts
Akutsu switch 3 for increasing by a predetermined width ΔT than
4. Various switches including a lukewarm switch 35 for decreasing the hot water temperature by a constant width ΔT from the set temperature Ts, and a plenty switch 36 for increasing the water level by a fixed amount ΔL from the set water level Ls are arranged. .

The temperature setting means in the claims is the temperature setting switch 31, the water level setting means is the water level setting switch 32, the temperature changing means is attached to the switch 34 and the lukewarm switch 35, and the hot water commanding means is. Plenty of switches 36 are supported.

The controller 22 is composed of, for example, a microcomputer, is equipped with an arithmetic control unit 41, a memory 42, and an internal timer 43, and inputs data from the switches of the remote controller 20, the water level sensor 10, and the like. Based on the detection signal from the temperature sensor 12 and the like, the combustion control of the gas burner 14 for reheating and the water heater 18 is performed, and the movable parts 8, 17, ... Are controlled.

Then, the changed temperature temporary holding means and the temperature control means in the claims are constituted by the controller 22, and the holding time varying means in the claims are constituted by the water level sensor 10 and the controller 22. The addition hot water means and the hot water supply means in the claims are the controller 22 and the water heater 1.
And 8.

Next, the operation of the automatic bath apparatus having the above structure will be described with reference to the flow chart shown in FIG.

Here, the temperature setting switch 3 is previously set.
1 and the water level setting switch 32 are operated to set the temperature Ts.
And the set water level Ls is determined, and the automatic operation switch 33 is operated to set the automatic hot water filling / warming hot water mode. Therefore, in the bathtub 2, the preset temperature T is already set.
It is assumed that the hot water of s is automatically filled to the set water level Ls.

In this state, the controller 22 determines whether or not the hot switch 34 is operated (step 2). If the hot switch 34 is not operated, it is next determined whether or not the lukewarm switch 35 is operated (step 3).

Hot switch 34 and lukewarm switch 35
If neither is operated, after setting the flag F to "0" to indicate that the target temperature T has not changed.
(Step 4) Next, it is determined whether or not the plenty of switches 36 have been operated (Step 7).

Here, when the plenty of the switch 36 has been operated, the controller 22 opens the open / close valve 17 and controls combustion so that hot water of the target temperature T (= Ts) is discharged from the water heater 18. At the same time, the circulation pump 8 is activated to move into the bathtub 2 beyond a set water level Ls by a fixed amount (for example, 2
Only 0 liters of water is poured (step 8).

The temperature of this hot water is the target temperature T (= Ts)
Therefore, the feeling of bathing at the temperature T can be continued as it is without any sudden increase or decrease in the temperature of the hot water.
After that, the process proceeds to step 10.

On the other hand, when the switch 36 is not fully operated in step 7, the controller 2
2 ignites the burner 14 and activates the circulation pump 8 when the hot water temperature T _F falls below the target temperature T, based on the detection output of the temperature sensor 12, to reheat to the target temperature T. The reheating may be performed until the pump 8 is started at a predetermined time, the burner 14 is ignited, and the hot water temperature T _F reaches the target temperature T.

Further, based on the detection output of the water level sensor 10, the set water level L preset by the water level setting switch 32 is set.
When the water level becomes lower than s, the on-off valve 17 is opened to perform combustion control so that hot water having the target temperature T is discharged from the water heater 18, and the circulation pump 8 is activated to set the water level Ls into the bathtub 2. Add water until the temperature reaches (step 9).

That is, the temperature of this supplemental water is the target temperature T
Since it is the same as (= Ts), the bath temperature at the temperature T can be continued without any sudden increase or decrease in the bath temperature. After that, the process proceeds to step 10.

At step 10, it is judged whether or not the flag F is "0". If the flag F is "0", neither the hot switch 34 nor the lukewarm switch 35 is operated, and the target temperature T It is judged that there is no change, and the process returns to step 2.

On the other hand, when the hot switch 34 is operated in step 2, the current hot water temperature T _F of the bathtub 2 detected by the temperature sensor 12 is fetched (step 1
1), the hot water temperature T _F is a certain range α (eg 1
It is determined whether or not the temperature range is lower by (° C.) (step 12).

When the hot water temperature T _F is out of the temperature range lower than the set temperature Ts by the constant width α, the set temperature Ts is set as the target temperature T for keeping the hot water (step 14). Further, when the hot water temperature T _F is within the temperature range lower than the set temperature Ts by the constant width α, the temperature increased from the hot water temperature T _F by the predetermined width ΔT (for example, 1 ° C.) is set to the target temperature T _F. (= T _F + ΔT) (step 16), and the target temperature T is reheated (step 13).

Therefore, when the hot switch 34 is operated only once for the first time, the hot water temperature is higher than the current hot water temperature T _F , and a "hot" bathing sensation can be enjoyed.

In step 3, if the lukewarm switch 35 is operated, the controller 22
Opens the on-off valve 17 without burning the water heater 18,
The circulation pump 8 is activated to inject water into the bathtub 2 (step 15).

The amount of water injection ΔQ in this case is calculated by the arithmetic control unit 41.
Is determined so as to satisfy the following relational expression.

Qs · Ts + ΔQ · Tc = (Qs + ΔQ) · (Ts−ΔT) (where Qs = k · Ls) (1) where Ts is the set temperature, Ls is the set water level, and Tc is detected by the temperature sensor 19. The entered water temperature, ΔT is a constant width (for example, 1 ° C.) in which the temperature should be lowered, and k is a conversion coefficient to the amount of water.

It should be noted that instead of the set temperature Ts, the present hot water temperature T _F detected by the temperature sensor 12 is set to the set water level Ls.
Of the current water level L ₀ detected by the water level sensor 10 instead of
May be used respectively.

In this way, when the lukewarm switch 35 is operated, for example, only once at the beginning, the temperature of the hot water is lowered by ΔT from the set temperature Ts, and a "slimy" bathing feeling can be enjoyed.

Then, the controller 22 outputs (T-ΔT)
The temperature determined by is set again as the target value T for the next combustion control (step 17).

When the hot switch 34 or the lukewarm switch 35 is operated to change the target temperature T, after the flag F is set to "1" in order to show that the change has occurred. (Step 18), a predetermined holding time β is set in the internal timer 43 and the internal timer 43 is activated (step 19).

This holding time β is determined by taking into consideration the average time required for a bather to go up and the next person to take a bath and the average time spent in the washroom while taking a bath. It is set in advance so as to have an intermediate value of. For example, it is set to about 10 minutes, which is shorter than the conventional fixed time.

Subsequently, the controller 22 determines whether or not the ample switch 36 has been operated (step 7).

Here, when the plenty of switches 36 have been operated, the controller 22 discharges hot water of the target temperature T from the water heater 18 and sets the set water level Ls into the bathtub 2 as in the case described above. A certain amount (for example, 20 liters) of hot water is poured over the temperature (step 8).

Also in this case, since the temperature of the hot water is the same as the target temperature T after the change, there is no abrupt increase or decrease in the hot water temperature, and the feeling of bathing at that temperature T can be continued. .

Also, in step 7, there are plenty of switches 36.
If is not operated, the controller 22 reheats the water to the target temperature T if the hot water temperature T _F is lower than the target temperature T, and sets the water temperature if it is lower than the set water level Ls. Hot water is added until the water level reaches Ls (step 9).

Since the temperature of the hot water in this case is also the same as the target temperature T after the change, there is no abrupt increase or decrease in the hot water temperature, and the feeling of bathing at that temperature T can be continued.

Next, at step 10, it is judged whether or not the flag F is "0". When the flag F is not "0", that is, when F = 1, the controller 2
2 determines whether or not the hot switch 34 is operated (step 26), and if the hot switch 34 is operated, returns to step 11. Also, switch 3 that is hot
4 is not operated, next, the lukewarm switch 35
Is operated (step 27), and if the lukewarm switch 34 is operated, the process returns to step 15.

If neither the hot switch 34 nor the lukewarm switch 35 is operated, the controller 2
2 determines whether or not the user is taking a bath based on the detection output of the water level sensor 10 (step 22).

If it is determined that the user is taking a bath, step 1
Returning to step 9, the time measured by the internal timer 43 until then is cleared and the holding time β is set again. That is, if the bathing is continued, the internal timer 43 is consequently reset repeatedly, so that the internal timer 43 does not expire. Therefore, the changed target temperature T
Since the hot water in step 8 or the warming and adding hot water in step 9 is performed underneath, the feeling of bathing at the temperature T can be continuously enjoyed.

In step 22, if it is taken out of the bathtub 2 to change to the next bather, or if the person leaves the bathtub 2 temporarily to wash his / her body, it is determined that he is not taking a bath. Therefore, at this time, the controller 2
For No. 2, it is judged whether or not the holding time β of the internal timer 43 has elapsed and the time has expired (step 23).

Within the holding time β of the internal timer 43,
If the time is not yet up, return to step 7.

Then, after that, it is judged in step 22 whether or not the user is taking a bath again. Therefore, even if the bath is temporarily taken out from the bathtub 2 to wash the body, the bathtub is again taken before the holding time β elapses. If immersed in 2, the internal timer 43 is reset. Therefore, even in this case, the changed target temperature T
Underneath, the hot water in step 8 or the warming and adding water in step 9 is performed, and you can continue to enjoy the feeling of bathing.

On the other hand, the bathtub 1 to be replaced with the next bather
In case of the above, the internal timer 43 is timed up after the holding time β has elapsed in step 23. In this case, therefore, the target temperature T is returned to the set temperature Ts (step 24), and the process proceeds to step 1. Return to the initial state.

[0073]
