Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath reservation operation device for automatically boiling a bath by a reservation operation.

[0002]

2. Description of the Related Art In a bath water heater, in addition to a device of a type in which a boiling operation is started immediately when a user performs a predetermined boiling operation, a bath reservation operating device is installed, and a bath set by a user is set. There is a device of a type in which a boiling operation is started so as to be heated at a reserved time which is a boiling time.

[0003] The bath reservation operation device in the latter bath water heater has an automatic operation in which a reservation time is set after a reservation switch for starting a reservation operation is turned on, and the bath is heated to a preset hot water amount and temperature. When the switch is turned on, the bath can be heated to the hot water amount and temperature corresponding to the automatic operation switch at the reserved time. Therefore, the conventional bath reservation operation device is a single-function device that only heats up to the hot water amount and temperature set in the automatic operation switch.

[0004] On the other hand, the amount and temperature of the boiling water of the bath vary depending on the individual user, or even a single user depending on the demand at each time. Then, the single-function bath reservation driving device as described above cannot cope with various preferences of the user.

[0005] Since the bath reservation operation device is provided with various switches for changing the set hot water amount and the set temperature, if the operation of these switches is linked to the operation of the automatic operation switch, the amount of hot water, the temperature, etc. Fine setting is possible.

[0006]

However, if the operation of switches other than the automatic operation switch is unconditionally enabled in the reserved operation, a setting error may be caused due to complicated operation. If the boiling water temperature is too hot or too warm due to a mistake in setting the boiling temperature, a large thermal load is applied to the body of the user who took a bath, which is not preferable.

By the way, there is a case where the reservation operation is set in a state where there is residual water in the bathtub. In such a case, the above-mentioned conventional bath reservation driving apparatus is configured to start the automatic operation a predetermined time before the reservation time, ignoring the remaining water.

Then, when there is a lot of residual water in the bathtub,
The poured hot water mixes with the remaining water, causing the water temperature to drop and the water not to boil by the reserved time. Also, if there is little remaining water in the bath tub, the bath tub will be filled with hot water poured at the set temperature and it will boil well before the reservation time, and even though it has been boiled up, the reservation time May be pinched.

In the calculation of the residual water amount in a so-called simple automatic bath water heater that only supplies hot water and does not perform reheating, reheating is performed only for a predetermined time to reheat the hot water and the water is supplied from the piping to the bathtub and the reheating. It circulates with the return pipe, and the amount of residual water in the bathtub is calculated from the amount of increase in the bath temperature with respect to the given amount of heat. Since the temperature of the pipe varies depending on the outside air temperature, the amount of increase in the bath temperature changes with the outside air temperature. The efficiency of the circulation of the bathtub, the reheating line and the hot water from the reheating line to the reheating line is called system efficiency.

Unless the system efficiency is taken into account in the calculation of the residual water amount by simple auto, in the summertime when the outside air temperature is high and the temperature of the piping rises, the residual water amount is calculated to be smaller than the actual amount because the hot water temperature rises with a small amount of heat. The amount of pouring water is increased and hot water may overflow from the bathtub. Also, in winter when the outside air temperature is low and the temperature of the pipes falls, the hot water temperature does not rise unless a large amount of heat is given, so the remaining water amount is calculated more than the actual amount and the pouring volume decreases, or sometimes pouring is performed. The automatic operation may be completed without the operation. further,
Unless system efficiency is taken into account when boiling the bath, it is difficult to boil the bath at the reserved time.

In order to prevent such inconvenience, conventionally, the system efficiency has been manually adjusted by switching jumpers and dip switches according to the season.

However, in this case, it is not possible to precisely control the system efficiency in response to daily fluctuations in the outside air temperature, and it is not possible to perform a comfortable bath reservation operation.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a bath reservation driving apparatus which can secure a margin for a reservation setting error and can perform various types of bath reservation driving.

It is another object of the present invention to provide a bath reservation operating device that can boil a bath at a reservation time regardless of the presence or absence of residual water in a bathtub.

It is a further object of the present invention to provide a bath reservation operating device capable of accurately performing a bath reservation operation without being affected by fluctuations in the outside air temperature.

In the present invention, the type and layout of the operation switches of the operation unit 1 and the display contents and layout of the display unit 2 are not limited to these, and can be freely set. Further, the pouring amount and the bath temperature are not limited to the numerical values described above.

A reservation driving operation by the bath reservation driving device will be described with reference to FIG. Here, FIG.
The reservation driving operation by the bath reservation driving device installed in the bathroom shown in FIG.

First, when the reservation switch 18 is turned on (step S1), a reservation display section 24 indicating that a reservation operation is set is turned on, a time display section 25, and a time setting switch which is an operable switch. 19, automatic operation switch 11, gather switch 12, fill switch 1
3 and the hot water volume control switch 22 are blinked (step S2). Here, the blinking of the switch means that the switch itself blinks, the display provided near the switch blinks, or the display of the type pressed on the display unit distant from the switch indicates such display. Flashing. Also, instead of blinking, the color of the display is changed. When the switch is pressed, the switch itself emits light, for example, yellow, and when the switch is pressed, the light emission color of this switch is changed from yellow to, for example, green. May be.

Here, the switches related to the contents of the boiling water that flashes when the reservation switch 18 is turned on are limited to switches that do not apply a large thermal load to the body of the user who takes a bath even if a setting error is made. ing.

That is, the switches for adjusting the contents of the boiling water include the automatic operation switch 11 and the collecting switch 1.
2. The filling switch 13, the hot water amount switch 15, which is the hot water amount adjusting switch 22, the generous switch 16, and the hot water temperature switch 17. The bath temperature is too hot or too warm. Then, if the user is inadvertently immersed in the bathtub, there is a possibility that a large thermal load (a feeling such as “hot” or “cold”) is applied to the body. On the other hand, the automatic operation switch 11, which boils up to the set temperature and the set hot water amount,
With the collecting switch 12 and the filling switch 13 for boiling up to a temperature slightly higher or lower than the set temperature, the hot water amount switch 15 for adjusting the set hot water amount, and the generous switch 16, such a problem does not occur even if a setting error is made. .

Therefore, as described above, a switch that does not have such a possibility is blinked as being operable in a limited manner, and a margin for a reservation setting error is secured.

If one of the switches for instructing the operation related to the change of the automatic driving condition described above is provided with a setting switch for detecting bathing and changing the hot water temperature, for example, Before this, the set hot water temperature is set low (for example, the set temperature minus 1.5 ° C.), and when the presence of the input person is detected by a pressure sensor or the like, the temperature is raised to the set temperature.

Next, it is determined whether or not the time setting switch 19 has been operated (step S3). When the time setting switch 19 is operated in the state where the reservation switch 18 is turned on, the reservation time is set. Therefore, if the time setting switch 19 is operated and the reservation time is set in step S3, the reservation time is set. The reservation time is received (step S4). On the other hand, if the time setting switch 19 is not operated, it is considered that the user wants to heat up to the already set reservation time, so the previous reservation time is inherited as it is (step S5).

After step S4 or step S5, the time setting switch 19 is turned off and the time display section 25 is turned on (step S6).

Then, the flashing automatic operation switch 11,
A predetermined boiling program set by selecting a predetermined switch from the hot water amount switch 15 and the full switch 16 which are the collecting switch 12, the filling switch 13 and the water amount adjusting switch 22 is received (step S7). The boiling program is set by selecting one of these switches or a plurality of switches under a predetermined combination. Thus, various types of bath reservation driving are enabled.

Here, in the present embodiment, the following first to tenth boiling programs can be set. However, at least one of these boiling programs may be settable, or another boiling program may be settable.

The first boiling program is set by selecting only the automatic operation switch 11. The first boiling program is a program for pouring up to a set amount of hot water, boiling to a set temperature, and keeping the temperature for a predetermined time (for example, 4 hours). It is.

The second boiling program is set by selecting only the collecting switch 12, so that the water in the bathtub is raised to a temperature higher by a predetermined temperature (for example, 2 ° C.) than the set temperature without pouring. It is a program to boil.

The third boiling program is set by selecting only the filling switch 13, and the temperature of the water in the bathtub is reduced to a predetermined temperature (for example, 2 ° C.) lower than the set temperature without pouring. It is a program to boil.

The fourth boiling program is a program which is set by selecting only the hot water amount adjusting switch 22. The fourth boiling program is a program for pouring the hot water amount along the hot water amount adjusting switch 22 and boiling it up to the set temperature.

The fifth boiling program is set by selecting the automatic operation switch 11 after selecting the collecting switch 12 and pouring up to the set hot water amount, and only a predetermined temperature (for example, 2 ° C.) from the set temperature. This is a program for keeping the temperature for a predetermined time (for example, 4 hours) after boiling it to a high temperature.

The sixth boiling program is set by selecting the automatic operation switch 11 after selecting the filling switch 13 and pouring up to the set hot water amount, and only a predetermined temperature (for example, 2 ° C.) from the set temperature. This is a program for keeping the temperature for a predetermined time (for example, 4 hours) after boiling it to a low temperature.

The seventh boiling program is set by selecting the automatic operation switch 11 after selecting the hot water amount adjusting switch 22, and pouring up to the hot water amount along the hot water amount adjusting switch 22 and boiling it up to the set temperature. After that, the program keeps the temperature for a predetermined time (for example, 4 hours).

The eighth boiling program is set by simultaneously selecting the collecting switch 12 and the filling switch 13, and is a program for boiling water in a bathtub to a set temperature without pouring water.

The ninth boiling program is set by selecting the hot water switch 12, the hot water control switch 22 and the automatic operation switch 11, or the hot water control switch 22, the hot water switch 12, and the automatic operation switch 11 in that order. This is a program for pouring up to the amount of hot water along the hot water amount adjusting switch 22, boiling the hot water to a temperature higher than the set temperature by a predetermined temperature (for example, 2 ° C.), and keeping the temperature for a predetermined time (for example, 4 hours).

Then, the tenth boiling program is performed in the order of the filling switch 13, the hot water amount adjusting switch 22, the automatic operation switch 11, or the hot water amount adjusting switch 22,
It is set by selecting the filling switch 13 and the automatic operation switch 11 in this order, and pouring up to the amount of hot water along the hot water amount adjusting switch 22 to set a predetermined temperature (for example, 2
This is a program for keeping the temperature for a predetermined time (for example, 4 hours) after boiling it to a temperature lower by (° C.).

When the boiling program set in this way is received, the switch selected for setting the boiling program is turned on, and the switches not selected are turned off (step S8).

Next, the presence or absence of residual water in the bathtub is checked (step S9).

If there is residual water in the bathtub in step S9, the residual water amount and residual water temperature are detected (step S9).
10). Here, the residual water amount can be determined by measurement using a pressure sensor or a flowing water switch, or by calculation from the amount of increase in the bath temperature with respect to a given predetermined amount of heat.
Further, the residual water temperature can be obtained by measurement using a thermistor.

When the residual water amount and residual water temperature are detected,
The required boiling time after pouring the required amount of water from the remaining water amount and the remaining water temperature, and the required pouring time from the remaining water amount to the set hot water amount are calculated (step S11). And
It is determined whether the previous time has been reached from the reservation time by the sum of the required time for boiling and the required time for pouring (step S12), and if it has, the reserved operation according to the set contents (boiler program) is performed. Execute (Step S
13). In addition, when the bath has boiled up after the reserved operation is completed, an end buzzer may be sounded to notify the user to that effect.

Here, the boiling to the set temperature in the case where there is residual water can be performed by first boiling the residual water to the set temperature and then pouring hot water at the set temperature, or
First, hot water at a set temperature is poured into the remaining water to set the amount of hot water, and then reheating is performed to the set temperature.

On the other hand, if there is no remaining water in the bath tub in step S9, it is determined whether or not a predetermined time before the reserved time has arrived (step S14).
Then, when the time has arrived, the reserved operation according to the set contents is executed (step S13).

As described above, the presence or absence of residual water in the bathtub is checked, and if there is residual water, the reservation time is calculated by adding the required time for boiling and the required time for pouring obtained from the residual water amount and the residual water temperature. The reserved operation is started before the start of the operation, and if there is no remaining water, the reserved operation is started only a predetermined time before the reserved time. Instead, the bath can be heated at the reserved time. Thereby, it is possible to prevent inconvenience that the water does not boil before the reserved time or the water is heated well before the reserved time.

The process of detecting the remaining water amount and adjusting the reserved operation start time from the remaining water amount and the remaining water temperature may be omitted. In this case, the reserved driving is uniformly started a predetermined time before the reserved time.

Here, in the reserved operation, it is desirable that the operation is performed with system efficiency. That is, the system calculates the residual water amount, for example, twice, which measures the rise amount of the bath temperature with respect to the heat amount given by the reburning combustion, to determine the system efficiency, and to operate according to the system efficiency. Alternatively, the outside air temperature is measured by an outside air thermistor. For example, when the outside air temperature is 20 ° C., the system efficiency is set to 100%. When the outside air temperature is lower than this, the system efficiency is set to, for example, 90%. The system efficiency is set to, for example, 110%, and operation is performed according to the set system efficiency.

In this way, the required time during reheating and pouring does not fluctuate due to the outside air temperature, and the remaining water amount calculation by the simple auto becomes accurate, and is not affected by the fluctuation of the outside air temperature. Thus, it is possible to accurately perform the bath reservation operation.

[0061]

As apparent from the above description, the following effects can be obtained according to the present invention.

(1) Switches that do not cause a large thermal load to the user even if a setting error is made are made operable to a limited extent and blink, and a boiling program is set by these switches. Therefore, it is possible to secure a margin for a reservation setting error and to perform various types of bath reservation driving.

(2) When there is residual water in the bathtub, the reserved operation is performed before the reserved time by the sum of the required boiling time and the required pouring time obtained from the residual water amount and the residual water temperature. So that if there is no remaining water, the reserved operation is started only a predetermined time before the reserved time, so whether or not there is residual water in the bathtub,
It becomes possible to boil the bath at the reserved time. Therefore, it is possible to prevent inconvenience that the water does not boil before the reserved time or the water is heated well before the reserved time.

(3) Since the reserved operation is performed with the system efficiency, the required time during reheating and pouring does not fluctuate due to the outside air temperature, and the calculation of the remaining water amount by the simple auto becomes accurate, and the outside air temperature is reduced. It is possible to perform the bath reservation operation accurately without being affected by the fluctuation of the bath.
