DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a bathtub with a water heater.

[0002]

2. Description of the Related Art In a bathtub with a water heater, a control method such as a hot water filling operation is different depending on a depth and a type (Western type, Japanese type) of a bathtub to be used. It was necessary to switch the setting of the construction conditions and use conditions of the bath kettle with a water heater according to the depth and type.

In such a case, conventionally, the setting of the working condition and the use condition is switched by a dip switch (hard dip switch) provided on an electrical board of a bathtub with a water heater.

[0004] In addition, there has been a configuration in which a dip switch is set from the remote controller using a remote controller and special software (soft dip switch).

[0005]

However, since the (hard) dip switches are small, the settings have to be switched one by one at the end of each pin, which is troublesome and troublesome. In addition, there was a high possibility that the user would make a mistake in setting because it was difficult to see.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a bath kettle with a water heater which can easily switch the setting according to construction conditions and use conditions. Is to provide.

[0007]

According to a first aspect of the present invention, there is provided a bath kettle with a water heater, which comprises a bath kettle body having a hot water supply function and a bath kettle with a water heater provided with a remote controller for operation. It is characterized in that a setting input for performing a setting suitable for the user can be input by a driving operation means of a remote controller according to a guide.
Here, the operation operation means of the remote controller is a normal switch or button for operating and setting a bathtub with a water heater, such as an operation switch of a water heater or a bathtub or a temperature setting button. The guide may be visual, such as a display screen, or auditory, such as a voice guide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) FIG. 1 is a view showing a configuration of a bathtub with a water heater according to one embodiment of the present invention. A hot-water supply heat exchanger 2 is disposed above the hot-water supply can 1, a gas burner 3 is provided below the hot-water supply heat exchanger 2, and a combustion air is supplied to the gas burner 3 on a lower surface of the hot-water supply can 1. Hot water supply combustion fan 4 is attached. The hot water supply heat exchanger 2 is connected with a water supply pipe 5 for supplying water from city water or the like and a hot water supply pipe 7 for supplying hot water heated by the hot water supply heat exchanger 2, and between the water supply pipe 5 and the hot water supply pipe 7. Are connected to both ends of a bypass pipe 9. The water supply pipe 5 is provided with a water amount sensor 6 for detecting a flow rate of incoming water, the tapping pipe 7 is provided with a flow control valve 8, and the bypass pipe 9 is provided with a bypass flow control valve 10. When the callan or the like provided at the end of the tapping pipe 7 is opened, the water quantity sensor 6
Detects the amount of water equal to or more than the minimum operating flow rate, the gas burner 3 is ignited, and the water flowing from the water supply pipe 5 is heated by the hot water supply heat exchanger 2 and is discharged from the water discharge pipe 7. The water that has passed through the bypass pipe 9 is mixed and the hot water is discharged from the caran or the like.

A bath heat exchanger 13 is provided above the bath can 12.
The gas burner 1 is provided below the bath heat exchanger 13.
The gas burner 14 is provided on the lower surface of the bath can 12.
Is provided with a bath combustion fan 15 for supplying combustion air to the bath. The bath heat exchanger 13 is connected to a bath return pipe 21 and a bath going pipe 22 connected to a circulation adapter 32 of a bathtub 31, and the bath return pipe 21 is connected to a bath pump 2.
3 and a bath water flow switch 24 are provided. Then, the bath pump 23 is operated to circulate the hot water in the bathtub into the additional heating circuit (bath return pipe 21 and bath going pipe 22),
By heating the hot water passing through the bath heat exchanger 13 by burning the gas burner 14, the hot water in the bathtub can be additionally heated.

Two drop pipes 25, 2 from the tapping pipe 7
8, one dropping pipe 25 is connected to the bath return pipe 21, and the other dropping pipe 28 is connected to the bath going pipe 22. The dropping pipe 25 is provided with an on-off valve 26 and a check valve 27, and the dropping pipe 28 is provided with an on-off valve 29 and a check valve 30. Thus, the on-off valves 26 of the two drop pipes 25, 28
And 29 are opened and the hot water heated by the hot water supply heat exchanger 2 and discharged to the tapping pipe 7 is dropped and supplied to the bath return pipe 21 and the bath going pipe 22 through the pipes 25 and 28, and this hot water is supplied to the bath return pipe 21 and the bath The water is dropped into the bathtub 31 by the two transports from the outgoing pipe 22, and the bathtub 31 is filled with hot water and refilled (added water).

The hot water supply can 1 and the bath can 12 are evacuated through a common exhaust port 11. Also,
Gas pipe 17 provided with a main solenoid valve 20 and a gas proportional valve 19
, Two gas pipes 16a and 16b are branched,
The gas pipe 16a is connected to the gas burner 3, and the on-off valve 18
Is connected to the gas burner 14.

When the hot water is automatically dropped into the bathtub to a predetermined depth as described above, an operation for calculating the bathtub cross-sectional area is executed to obtain the bathtub cross-sectional area, and the bathtub cross-sectional area and the predetermined depth are calculated. What is necessary is just to drop hot water of the amount of water approximately equal to the product of the products into the bathtub. However, the calculation method for obtaining the bathtub cross-sectional area differs between a Japanese bath whose bottom and top surfaces are almost equal, and a Western bath whose top surface is larger than the bottom, and the bathtub depth also differs. . For this reason,
If the setting is made in accordance with either one, the error increases on the other side, so when installing a bathtub with a water heater, it is necessary to set the shape of the bathtub.

Such a setting can be performed by a remote controller for operating a bathtub with a water heater. That is, by operating an operation switch or an operation button provided on the remote controller as predetermined, the remote controller can be switched from the normal mode to the setting mode.
For example, in the case of the remote controller 41 as shown in FIG. 2, it may be possible to switch to the setting mode by holding down the bath automatic switch 46 for about 5 to 10 seconds. Alternatively, by pressing the up button 44 three times and the down button 45 three times, or simultaneously pressing the up button 44 and the down button 45 three times,
The mode may be switched to the setting mode. By operating the operation switch or the operation button of the remote controller 41 as predetermined, the remote controller 41 can be returned from the setting mode to the normal mode.

FIG. 2 shows a state in which the remote controller 41 has been switched to the setting mode in this manner, and a message 43 of “setting” is displayed on the display section 42. On the screen of the display section 42, the bathtub shape can be set. By pressing the up button 44, the bath is set to a Western style bus, and by pressing the down button 45, the Japanese style bath is set. Then, when the bathtub shape is set to a Japanese bath, when the hot water is dropped into the bathtub, the amount of hot water dropped into the bathtub is calculated by a calculation method that does not consider the area ratio between the bottom surface and the top surface of the bathtub. Also, if the bathtub shape is set to a Western style bath,
The amount of hot water dropped into the bathtub is calculated by a calculation method that takes into account the area ratio between the bottom surface and the top surface of the bathtub. When the bathtub shape is set,
As shown in FIG. 3, the screen of the display unit 42 switches to the next setting item.

FIG. 3 shows a setting mode of the bathtub height (installation height of the bathtub). When the up button 44 is pressed, the bathtub height is set to -3 m to +7 m, and when the down button 45 is pressed, the bathtub height is set. Is set to −5 m to −3 m. The bathtub height here refers to the height of the installation position of the bathtub with respect to the bath pump 23. When the installation height of the bathtub 31 is normal (−3 m to +7 m), the bathtub 31
When the bathtub 31 is located at a lower position, the self-priming of the bath pump 23 and the air purging in the pipes take time, so that the circulation is It is necessary to set the judgment time for judgment, the water level stabilization wait time after the circulation judgment is OK, the bath water circulation time after the reheating operation, etc. to be set longer than usual, and to operate. It can be set in this mode.

FIG. 4 shows a setting mode of the bathtub size. When the up button 44 is pressed, the bathtub is set to a normal size, and when the down button 45 is pressed, the bathtub is set to a large size. When the bath is set to a normal-sized bathtub, the temperature of the hot water in the bathtub 31 is lower than the temperature lower than the set temperature Ts by a constant temperature X (that is, Ts−
X or less), the gas burner 14 of the bath kettle with a water heater is burned at the maximum capacity, and when Ts-X is reached, the combustion capacity of the gas burner 14 is reduced (for example, the combustion capacity is reduced by half).
To The operation is performed so that hot water is discharged from the circulation adapter 32 of the bathtub 31 and does not hit the bather's feet or the like. On the other hand, when the bath is set in a large bathtub, the gas burner 14 of the bath kettle with a water heater is burned at the maximum capacity from the beginning to the end when the bath is additionally heated. Thereby, in the case of a large-sized bath, reheating is extremely time-consuming, and the disadvantage that reheating is not completed even after 1-2 hours can be avoided, and reheating can be performed in the shortest time. Also,
In the case of a large bathtub, comfort is maintained because there is a low possibility that a part of the body such as the feet of the bather is present near the circulation adapter 32. In addition, when it is set to a large bathtub, a safety mode for forgetting to close the drain plug of the bathtub (circulation adapter provided in the bathtub with a pressure sensor for detecting the water level in the bathtub of the bathtub with a water heater even if the bath is filled with a predetermined amount of water) To stop the bath if the water level cannot be detected through the system.) I do.

Hereinafter, although the state of the remote controller is not shown, other various construction conditions and use conditions described below can be set by the remote controller.

For example, the heat change switching mode (switching of gas type) is to set whether the gas type to be used after installation is a shipping gas type (for example, 6C) or something other than that, and according to the setting. The control amount (control table) of the gas proportional valve current is switched.

The exhaust length mode is for setting whether the exhaust extension length is standard (within 2 bends of 3 m) or other, and accordingly, the hot water supply combustion fan 4 and the bath combustion fan 15 are set accordingly. Change the fan rotation speed.

In the bath water level switching mode, whether or not a water level sensor is mounted is switched, and the target water level when the bath is dropped is changed by about 5 cm accordingly. When the water level sensor is mounted, there is little possibility that hot water overflows from the bathtub. Therefore, when the water level sensor is mounted, the target water level is set higher by about 5 cm.

In the bath water amount switching mode, the set pouring amount is adjusted, for example, in increments of 50 liters in a fixed-rate pouring type bath water heater. That is, each time the up button is pressed, the volume increases by 50 liters, and each time the down button is pressed, the volume decreases by 50 liters.

In the heating hot water temperature setting mode, the hot water temperature is switched between 80.degree. C. and 60.degree. C. depending on whether it is bathroom heating or floor heating.

The bath pipe extension mode is for setting whether the bath pipe is standard (within 7 bends and 5 m) or not, and the control method is set similarly to the case of setting the bath height. change.

In the hot water continuous combustion mode, the continuous hot water combustion is y
The setting is es or no. If yes, the stop of hot water supply combustion is normally canceled in 60 minutes.

The bath / heating freeze prevention mode is for setting whether the bath / heating freeze prevention operation is yes or no.
If yes, the operation of the bathtub with the water heater is prohibited from stopping to prevent freezing.

The bath / heating freezing prevention mode is for setting whether the bath / heating freezing prevention operation is yes or no.
If yes, the pump is prohibited from circulating hot water in the pipes to prevent freezing.

The 24-hour heat retention mode is for turning off the standard mode (maximum heat retention time of 9 hours) to make the heat retention time of hot water in the bathtub continuous and unlimited.

[0031]

According to the bath kettle with the water heater according to the first aspect, the setting suitable for the construction condition or the use condition can be performed from the operation operation means of the remote controller according to the guide, so that it can be installed in the bathroom or kitchen. The settings can be easily made by operating the attached remote controller.

[0032] In the bath kettle with a water heater according to claim 2,
Since the input method of the setting input is different from the normal driving operation, the risk of erroneous operation from the normal driving operation is reduced. In addition, since only one mode is displayed at the time of setting input, there is little possibility that the setting contents are mistaken on the display screen, and setting input can be performed easily and accurately.
