Description

[Detailed Description of the Invention] [Field of Use and Outline of the Invention] The present invention relates to a bath apparatus having an automatic water filling function for stopping the water filling operation when the inside of the bathtub reaches a target water level. The temperature of the hot water filling can be easily changed during the hot rolling operation.

[Prior Art and Problem] Recently, the bath equipment having an improved function has been widely used, and a bath equipment having an automatic water filling function for stopping the water filling operation when hot water of a predetermined temperature is supplied to a certain level in the bathtub has become popular. I started to do it.

An example of this type of bath device is shown in FIG.

The bath device shown in the figure is capable of performing a standard filling operation in which hot water at a temperature generally preferred as a bathing temperature (hereinafter referred to as standard temperature) is poured into the bathtub. Standard water filling switch (4) operated when performing the above-mentioned water filling operation, and manual water filling switch (43) operated when performing water filling at a temperature freely set by the water temperature setting device (5) Is provided. Further, the wall surface of the bathroom is provided with a slimming switch (6) which is operated when the bathing water is warmed at a constant temperature (usually about 2 ° C.).

On the other hand, the combustion amount of the hot water supply gas burner (34) for heating the hot water supply heat exchanger (3) is controlled by the hot water temperature control circuit (8), and one of the hot water temperature control circuit (8) is controlled. The output of the standard temperature setting device (7) for setting the standard temperature and the output of the hot water temperature setting device (5) are selectively input to the input terminal of. Also, the hot water temperature control circuit (8)
A signal of a hot water temperature sensor (32) for detecting the temperature of hot water boiled in the hot water heat exchanger (3) is applied to the other input terminal of the hot water temperature control circuit (8). The combustion amount of the hot water supply gas burner (34) is controlled so that the detected temperature of the hot water supply temperature sensor (32) becomes equal to the set temperature of the standard temperature setting device (7) and the like.

A water level gauge (23) for detecting the water level in the bath is provided in the reheating circuit (21) formed so as to circulate between the bath (1) and the heat exchanger for reheating (2). .

Now, when the standard hot water filling switch (4) is turned on, the flip flop (49) is set, whereby the hot water filling valve (33) is opened and the main valve () inserted into the gas circuit to the hot water supply gas burner (34) is 36) opens and the hot water gas burner (34) begins to burn. Further, when the standard hot water filling switch (4) is turned on, the gate (71) corresponding to the standard temperature setting device (7) is opened, and the signal indicating the standard temperature set in the standard temperature setting device (7) is supplied with hot water. The signal from the hot water temperature sensor (32) for detecting the temperature is applied to the hot water temperature control circuit (8), whereby the standard temperature set in the standard temperature setting device (7) (generally as a bath temperature Hot water having a temperature corresponding to the (preferred temperature) is supplied to the bathtub (1) to start the filling operation.

When the inside of the bathtub (1) reaches a predetermined target water level, a water level gauge (23) arranged in the reheating circuit (21) outputs a water filling completion signal, and the water filling valve ( 33) is closed and the filling operation is stopped.

Next, after completion of the filling with water, the slimming switch (6)
When the switch is turned on, the timer (11) which operates in response to the turn-on signal outputs the "H" signal for a fixed time. Then, the water filling valve (33) is opened for a certain period of time while the hot water supply gas burner (34) is kept in the extinguished state, and a certain amount of cold water is supplied into the bathtub (1). That is, the bathing water in the reheating circuit (21) is kept at a constant temperature (usually about 2 ° C.) when the water supply operation is performed.
It is only slimy.

However, in the above-mentioned conventional one, when the slimming switch (6) is turned on, the water filling valve (33) is opened while the hot water supply gas burner (34) is kept in a fire extinguishing state to perform the water supply operation. Therefore, normally, when preparing a lukewarm bath, the lukewarm switch (6) is operated after the standard filling operation is completed. Therefore, in the above-mentioned conventional one, it is necessary to wait until the filling operation is completed once, and there is a problem that the operation when preparing a lukewarm bath becomes complicated.

The desired temperature is set in the hot water temperature setting device (5) shown in FIG. 6 and the manual hot water filling switch (43) is turned on to perform the manual hot water filling operation. It may be possible to drop the hot water into the bathtub (1), but in such a case, it is necessary to perform the temperature setting operation while being careful not to set the desired bathing temperature by mistake. Also, the filling operation becomes complicated.

<Regarding the Invention of Claim 1> The invention of Claim 1 is made in view of the above points,
"A slimming switch (6) that is operated when the bathtub (1) is warmed, a standard hot water switch (4) that is operated when performing a hot water filling operation at a predetermined temperature, and is further put into the bathtub (1). A hot water temperature control circuit (8) for controlling the temperature of hot water is provided, and when the standard hot water switch (4) is operated, a standard temperature signal from a standard temperature setting device (7) is sent to the hot water temperature control circuit (8). In the bath apparatus in which the hot water having the temperature is applied to the bathtub (1) ”, the lukewarm switch (6) is simply turned on even when the standard filling operation is in progress. Thus, it is an object of the present invention to prepare a bath with a loose eye when the filling of water is completed, thereby facilitating the operation of filling the lumber with hot water.

[Means] The technical means of the invention of claim 1 for solving the above problems will be described with reference to the conceptual diagram shown in FIG. 1. The technical means of the invention of claim 1 is "standard hot water switch. (4)
Alternatively, when the operation signal of either one of the lukewarm switch (6) is output, a bathing water presence signal is output when the water level in the bathtub is above a certain value, and a bathing water non-existence signal is output in the opposite case. Under the condition that a water level judging means is provided and a bathing water presence signal of the water level judging means, an operation signal of the slimming switch (6), a non-operation signal of the slimming switch (6) and an operation signal of the standard water filling switch (4) exist Then, the standard temperature signal is applied to the hot water temperature control circuit (8) to advance the hot water filling operation, and further there is a bathing water nonexistence signal and operation signals for the lukewarm switch (6) and the standard hot water filling switch (4). Under the conditions, a low temperature signal slightly lower than the standard temperature is applied to the hot water temperature control circuit (8) to advance the hot water filling operation. ”

[Operation] The above technical means operates as follows.

When there is no bathing water in the bathtub (1), a bathing water nonexistence signal is output from the water level determination means for detecting / determining the water level in the bathtub (1), and under this condition, the slime switch is provided. When only the standard hot water filling switch (4) is turned on without operating (6), the standard temperature is generated by the bath water non-existence signal, the operation signal of the standard hot water filling switch (4) and the non-operation signal of the lukewarm switch (6). A signal is generated and applied to the hot water temperature control circuit (8). Then, similarly to the conventional one described above, the standard temperature hot water is supplied from the bath device to the bathtub (1), and the standard hot water filling operation proceeds.

By the way, when the slimming switch (6) is turned on in the middle of the standard filling operation, the operation signal of the slimming switch (6) and the operation signal of the standard filling switch (4) which has already been generated. , The standard hot water switch (4)
At the time of the operation, a low temperature signal is generated by the bathing water nonexistence signal output from the water level determination means, whereby a low temperature signal slightly lower than the standard temperature signal is applied to the hot water temperature control circuit (8), As a result, the standard hot water filling operation is switched to the low temperature hot water filling operation. That is, even during the operation of the standard hot water filling, the hot water filling can be performed only by operating the slimming switch (6).

Next, the case where the slimming switch (6) is operated after the above-mentioned filling operation is completed will be described.

In this case, since the inside of the bathtub has been filled with water when the slimming switch (6) is turned on, a bathing water presence signal is output from the water level determination means when the slimming switch (6) is turned on. Then, the bathing water presence signal and the operation signal of the slimming switch (6) cause the operation of slimming the bathtub (1). That is, a water supply operation is performed to supply a certain amount of cold water into the bathtub (1), or the water in the bathtub is forcibly circulated in the reheating circuit for a certain period of time while the gas burner for reheating is kept in a fired state. However, this causes the water in the bathtub to be warmed by a certain temperature.

[Effect] The invention of claim 1 has the following unique effect.

Even during the standard hot water filling, by simply operating the lukewarm switch (6), the hot water filling can be performed at a temperature lower than that of the standard hot water filling. Therefore, after waiting for the hot water filling to complete, the switch (6 ) Is required to lower the temperature in the bathtub or to perform manual filling of water.

In addition, the slimming switch (6) used when lowering the temperature in the bathtub after completion of the filling of water functions also as a switch for lowering the temperature of the filling of water, and one switch has two functions. The number of switches can be reduced as compared with the case where two switches need to be provided for each of these functions.

[Embodiment] Next, an embodiment of the invention of claim 1 will be described with reference to the drawings.

As shown in FIG. 2, the water circuit and the gas circuit of the bath apparatus according to the embodiment of the present invention are configured in the same manner as the conventional one, and the heat exchanger (2) for reheating and the bath (1) A water temperature sensor (22) is arranged at the upstream end of the reheating circuit (21) formed so as to circulate between the two. In addition, a pulse generator (3) is provided in the water absorption circuit (30) on the upstream side of the hot water supply heat exchanger (3).
7) is inserted, and the pulse generator (37) is configured to output one pulse every time one water flows through the arrangement part. The number of pulses output from the pulse generator (37) is counted by the UP counter (38), and the counting result is input to a microcomputer (hereinafter abbreviated as microcomputer) (9).

Further, the output of the water level gauge (23) inserted in the reheating circuit (21) (in this embodiment, a water pressure gauge for detecting the water level in the bathtub (1) as pressure) is used for the first A / D conversion. Is applied to the input port of the microcomputer (9) through the device (40),
Further, a water temperature sensor (22) for detecting the temperature inside the bathtub (1)
Is applied to the input port of the microcomputer (9) via the second A / D converter (41).

On the other hand, the standard water filling switch (4) and the lukewarm switch (6) installed on the wall surface of the bathroom, and further the manual water filling switch (43) to be turned on when performing the manual water filling operation.
Is also connected to the input port of the microcomputer (9) in the same manner as the above-mentioned components. In addition, the hot water temperature setting device (5) that sets the desired bath temperature when performing manual hot filling is an up switch (51) that is operated when raising the set temperature and a down switch that is operated when lowering the set temperature. It is composed of a switch (52) and an UP / DOWN counter (50) for counting the number of times these switches are turned on, and the set temperature of the hot water temperature setting device (5) is displayed on a temperature display device (53). It has become.

Further, in this embodiment, when the operation is performed during the standard filling, the hot water filling operation is switched by 2 ° C. from the standard filling temperature, and when the operation is performed after completion of the filling, the bath water is changed from the current temperature. A temperature raising switch (62) provided to raise the temperature from 2 ° C. is provided.

Furthermore, a D / A converter (7
0) is connected, and the output of the D / A converter (70) is the hot water supply temperature attached to the hot water supply circuit (31) drawn downstream from the hot water supply heat exchanger (3). It is applied to the proportional control circuit (80) together with the output of the sensor (32). The proportional control circuit (80) controls the opening degree of the proportional valve (35) inserted into the gas circuit for the hot water supply gas burner (34). Then, in this embodiment, the proportional control circuit (80) corresponds to the hot water temperature control circuit (8) described in the section of the technical means.

A control program as shown in the flow chart of FIG. 3 is written in the microcomputer (9), and the operation of the bath apparatus according to the embodiment of the present invention will be described with reference to the flow chart shown in FIG.

First, after setting a flag F used for storing whether a slimming switch (6) or a temperature raising switch (62) described later is pressed to "0", whether the slimming switch (6) is turned on or not. Judge whether or not (see step of drawing code (81))
Then, if the slimming switch (6) is turned on, the flag F is set to "1" and "whether the temperature raising switch (62) is turned on or not" is determined by referring to the step of the drawing code (82). If the slimming switch (6) is not turned on, it is determined whether the temperature raising switch (62) is turned on without changing the content of the flag F (drawing reference numeral (83)).
See step). When the temperature raising switch (62) is turned on, the flag F is set to "2", and the output of the water level gauge (23) as the water level detecting means is read, and the output is at a constant level (filling completion level). Or a slightly lower level) or more, that is, whether there is a certain amount of bathing water in the bathtub (1) (drawing code (8
See step 4)).

In this embodiment, the functional unit of the microcomputer (9) that determines whether or not a certain amount of bath water is present in the bathtub (1) by checking the output of the water level gauge (23) is the technology described above. It corresponds to the water level determination means described in the section of the technical means.

Next, when the output signal of the water level gauge (23) is above a certain level and it can be determined that bath water is present in the bathtub, the CPU in the microcomputer issues a bath water presence signal and the program process conforms to the drawing code. The flow proceeds to the branch indicated by (85), and the contents of the flab F are judged. When the output of the water level gauge (23) is below the above level, the CPU outputs a bathing water nonexistence signal.

Next, as a result of checking the content of the flag F in the step of the above-mentioned drawing code (85), it can be confirmed that this is "0" and that neither the slimming switch (6) nor the temperature raising switch (62) has been turned on, The flag F is set to "0" again and the process returns to the step of the drawing code (81) for checking the closing signal of the slimming switch (6).

In this way, when a certain amount of bathing water is present in the bathtub (1), it is continuously monitored that the temperature increase switch (62) is turned on from the slimming switch (6). That is, the loop is connected to the drawing code (81) → (82) → (83) → (84) → (85) → (81).

Next, it is judged whether there is bathing water in the bathtub (1) (8
In step 4), if there is no output from the water level gauge (23) and it is judged that there is no bathing water in the bathtub (1), it is determined whether the standard water filling switch (4) has been operated. (Refer to the step of drawing code (87)), and if the standard hot water filling switch (4) is operated, the content of the flag F is checked (see the step of drawing code (89)).

As a result of checking the content of the flag F, the content of the flag F is "1", and the slimming switch (6)
If it is determined that the water has been added, the filling temperature T
Is set to "40 ° C" as a low temperature signal (refer to the step of drawing code (90)) On the other hand, when the content of the flag F is "2" as a result of checking the content of the flag F (standard hot water) If the temperature rise switch (42) is turned on before operating the tension switch (4), set the hot water temperature T to "44 ° C" (see the step of the drawing code (92)), or , If the content of the flag F is “0” (when neither the slimming switch (6) nor the temperature increasing switch (62) is turned on before operating the standard hot water filling switch (4)). Sets the filling temperature T to "42 ° C" as the standard temperature.

Next, the program control is transferred to the flow chart shown in the center of Fig. 3, and the hot water gas burner (34) for opening the hot water filling valve (33) and heating the hot water heat exchanger (3).
Open the main valve (36) inserted in the gas circuit to and
A temperature signal of the filling temperature T is applied to the proportional control circuit (80) via the D / A converter (70). Then, the proportional control circuit (80) compares the output of the D / A converter (70) with the output of the hot water supply temperature sensor (32) for detecting the temperature of the hot water heated by the hot water supply heat exchanger (3). Meanwhile, the combustion amount of the hot water supply gas burner (34) is controlled by adjusting the opening of the proportional valve (35) so that the hot water having the above-mentioned filling temperature T is supplied from the hot water supply heat exchanger (3). Yes (see step (93)).

Then, hot water having a temperature matching the filling temperature T is poured into the bathtub (1).
Is supplied to the water and the filling operation starts, and then the water level gauge (23)
Output determines whether the water level in the bathtub has reached the water level for completion of filling, and if the water level in the bathtub (1) has not reached the level for completion of filling water, the slime switch (6) is used during this filling operation.
It is monitored whether or not the temperature rise switch (62) is turned on (see steps (95) and (96) in the drawing). Then, if the slimming switch (6) is turned on during the water filling operation, the water filling temperature T is set to “40 ° C.” as the low temperature water filling temperature, and the water filling operation is performed. That is, when the lukewarm switch (6) is turned on even during the standard filling operation using the standard filling temperature of "42 ° C" set to the filling temperature T at the start of filling, The hot water of "40 ° C" is supplied to the bathtub (1) and the operation is switched to the hot water filling operation.

Therefore, compared to the above-mentioned conventional one in which it is necessary to turn on the slimming switch (6) to reduce the temperature in the bathtub after waiting for the completion of the standard filling operation, the filling operation of the lumber can be made easier. You can do it.

Further, in the case of this embodiment, when the hot water filling temperature T is set to “44 ° C.” and the lukewarm switch (6) is turned on while the hot water filling operation is being performed (high temperature hot water filling). But from that point on, the lukewarm filling operation proceeds.

Further, in this embodiment, when the temperature raising switch (62) is turned on in the step of the above-mentioned drawing symbol (96),
Since the content of the water filling temperature T is changed to "44 ° C" from that time, whether the standard water filling operation is in the process of supplying hot water of "42 ° C" to the bathtub (1). 40 ° C "
Regardless of whether the lukewarm hot water supplying operation is supplying hot water to the bathtub (1), hot water of "44 ℃" is supplied to the bathtub (1) from when the temperature increase switch (62) is turned on. As a result, the hot water filling operation is switched.

Then, when the water filling operation progresses and the water level in the bathtub (1) reaches the water level at which the water filling is completed, and a signal indicating this state is output from the water level gauge (23), the program control is performed according to the drawing code (94). From the step to the step (97), the filling valve (33) is closed and the hot water gas burner (34)
The main valve (36) inserted in the gas circuit to the valve is closed to complete the filling operation. After that, the program control will be returned to the first step of setting the flag F to "0".

In addition, from the step (87) for determining whether the standard water filling switch (4) has been turned on or not, the program control is performed for the step (86) for determining whether the manual water filling switch (43) has been turned on. When it is confirmed that the manual hot water filling switch (43) is operated when is moved, the output of the hot water temperature setting device (5) is read as the hot water filling temperature T. Then, after that, the same operation as the above-described filling operation is advanced using the above-mentioned filling temperature T (temperature set in the hot water temperature setting device (5)).

In the water filling completion state, a signal indicating the water filling completion state is output from the water level gauge (23), and when the slimmer switch (6) is operated in this state, the drawing reference numeral (84) → (85)
And the program control branches, and then the pulse generator (3
7) Reset the UP counter (38) that measures the output,
Further, the water filling valve (33) is opened with the main valve (36) inserted in the gas circuit to the hot water supply gas burner (34) being closed (while the hot water supply gas burner (34) is kept in the extinguished state).
That is, the supply water is supplied into the bathtub (1).

Then, when the signal of the UP counter (38) for counting the number of pulses output from the pulse generator (37) reaches a certain value and a certain amount of cold water is sent to the bathtub (1), the open water filling valve (33). ) Is closed, which causes the bath (1) to drop by a certain temperature (see drawing code (98)).

Further, in the above-mentioned water filling completion state, the temperature raising switch (62)
And the flag F is set to "2", the program control branches from the step of drawing code (84) to the step of (85) and then the process of drawing code (99) is executed.
The forced circulation pump (P) inserted in the reheating circuit (21) is driven, and the reheating gas burner (24) is burned,
Thereby, the bathing water in the bathtub (1) is circulated and heated to raise the temperature by a constant temperature (2 ° C.).

In the above embodiment, when the slimming switch (62) is turned on after the filling of water is completed, a certain amount of water is supplied to the bathtub (1). The forced circulation pump (P) may be driven for a certain period of time while maintaining the gas burner (24) in a fire extinguished state. In this case, since the reheating gas burner (24) is in a fire extinguishing state, the reheating heat exchanger (2) acts as a radiator, and the bath water circulates through the reheating circuit (21) to serve as the radiator. It is cooled by the acting heat exchanger (2), which makes the inside of the bath (1) warm by a certain temperature.

<Regarding the Invention of Claim 2> The object of the invention of Claim 2 is to make it possible to easily perform the operation of filling the lumber with hot water, like the invention of Claim 1 described above.

[Means] The technical means of the invention of claim 2 for solving the above-mentioned problem is to provide a "standard water filling switch (4) and a feed water switch (64), and an operation signal of the standard water filling switch (4). In a bath device equipped with a water filling device for supplying a set amount of hot water having a constant temperature to the bathtub (1) by input, water is supplied after the operation signal of the standard water filling switch (4) is input and before the water filling is completed. When the operation signal of the switch (64) is input, a control circuit is provided for supplying a certain amount of cold water to the bathtub (1) during or after the filling of water.

[Operation / Effect] The above technical means operates as follows.

When the standard filling switch (4) is operated, the filling operation is performed as in the conventional case.

During this filling operation, when the feed water switch (64) is operated to generate an operation signal for the switch, the output from the control circuit causes a certain amount of water to be added to the bathtub (1) during the filling operation or after the filling operation is completed. Cold water is supplied.

Therefore, it is necessary to operate the water supply switch (64) during the filling of water to prepare a lukewarm bath, and wait until the filling operation is completed before performing the sprinkling operation. The operation is simpler than the conventional one.

[Embodiment] Next, an embodiment corresponding to the invention of claim 2 described above is also the fourth embodiment.
It will be described with reference to FIGS.

As shown in FIG. 4, a hot water supply temperature sensor (32) and a hot water filling valve (33) are arranged in a hot water supply circuit (31) connected from the hot water supply heat exchanger (3) to the bathtub (1). In addition, a water meter (39) for measuring the amount of water supplied to the bathtub (1) is arranged upstream of the hot water supply heat exchanger (3).

Further, a proportional valve (35) and a main valve (36) located upstream thereof are provided in the gas circuit to the hot water supply gas burner (34) for heating the hot water supply heat exchanger (3). Proportional valve (3
The valve opening amount in 5) is controlled by the proportional control circuit (80). Then, the proportional control circuit (80) outputs the hot water temperature sensor (32) for detecting the temperature of hot water flowing out of the hot water heat exchanger (3), the output from the microcomputer (9), and the D / A. A signal indicating the standard filling temperature (normally 42 ° C.) converted into an analog amount by the converter (79) is applied.

Next, a control program having the contents shown in the flowchart of FIG. 5 is written in the microcomputer (9), and the operation of the bath apparatus of the above embodiment will be described below with reference to the flowchart.

When the power is turned on, the flag F used for storing whether or not the water supply switch (64) is turned on is set to "0".
Set to.

Next, wait for the standard hot water filling switch (4) to be turned on (see the step (102) of the drawing), and if the standard hot water filling switch (4) is turned on, open the main valve (36). The hot water supply gas burner (34) is set in the combustion state and the water filling valve (33) is opened, whereby the water filling operation is started. And, during this filling operation, the D / A converter (79)
A signal indicating the standard hot water filling temperature (42 ° C) is applied from the microcomputer (9) to the D /
It is in a state of being converted into an analog signal by the A converter (79) and applied to the proportional control circuit (80).

Then, the proportional control circuit (80) is a standard hot water from which the signal of the hot water supply temperature sensor (32) for detecting the temperature of hot water generated by heating in the hot water supply heat exchanger (3) is output from the microcomputer (9). The combustion amount of the proportional valve (35) is controlled so as to be equal to the tension temperature (see step (103) of the drawing).

When the water filling operation at the standard water filling temperature starts, the water level in the bathtub is monitored while judging the output of the water level gauge (23) (step of drawing code (104)), and if the water level in the bathtub has not reached the target water level, It is determined whether or not the water supply switch (64) is operated, and the water filling operation is performed while monitoring whether or not the water supply switch (64) is operated. Then, if the water supply switch (64) is operated during the filling of water, F is set to "1" (see the reference numerals (105) and (106) in the drawing).

Next, when the water filling operation progresses to reach the target water level in the bathtub and a signal indicating this is output from the water level gauge (23), the main valve (36) is closed and the hot water supply gas burner (34) is closed. Extinguish the fire and reset the water meter (39), and then check the contents of flag F. Then, the content of the flag F is "1".
If not (when the feed water switch (64) is not operated), the hot water filling is closed to complete the hot water operation, and conversely, when the content of the flag F is “1” (water filling operation) After confirming that the output of the water meter (39) becomes a constant value when the water supply switch (64) is operated on the way, that is, after supplying a constant amount of cold water to the bathtub (1). Close the water filling valve (33). This makes it possible to prepare a bath slightly warmer than the standard temperature (42 ° C).

In the above embodiment, if the water supply switch (64) is operated during the water filling, the water supply operation is performed after the water filling is completed. However, once the water supply switch (64) is operated, After the water filling operation is interrupted and the water filling operation is performed, the water filling operation may be continued again.
Alternatively, an independent water supply pipe may be separately provided in the bathtub (1), and a certain amount of water may be supplied to the bathtub (1) at the same time when the water supply switch (64) is operated.
