[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a reheating control device for a bath pot that performs reheating when it is detected that a person has bathed in a bathtub.
[0002]
[Prior art]
Usually, a bath pot reheating control device has a function of a heat retention mode, and a predetermined time (for example, 30 minutes) after the bath has boiled is in the operation mode of the heat retention mode. During this heat retention mode period, the temperature of the bath is controlled. When the bath temperature (bath water temperature) falls below the permissible range below the bath setting temperature, the reheating starts automatically, the bath temperature is maintained at the set temperature, and any time during the warming mode period. Hot water temperature is maintained in the bath.
[0003]
Recently, the signal of the water level sensor (pressure sensor) that detects the water level of the bathtub by the water pressure is taken in, and it is detected that a person has bathed in the bathtub by the change in the output of this water level sensor. If it is lower, it has been proposed to start chasing automatically, and in the case of a device with a higher level of function, it is automatically entered into the bathtub by pressing the high function operation button before the person takes a bath. A control method has been proposed in which the bath temperature is lowered by, for example, about 1.5 ° C to make it easier to enter the bathtub, and the bath temperature is raised to the set temperature immediately after detecting that a person has entered the bathtub. ing.
[0004]
In addition, the bath apparatus disclosed in Japanese Examined Patent Publication No. 6-84840 determines whether a bather is a child or an elderly person depending on the amount of water level change of a water level sensor (pressure sensor) when a person enters the bathtub. It has been proposed that when the child is a child, the set temperature of the bath is changed and set lower.
[0005]
[Problems to be solved by the invention]
For example, when taking a bath in winter, even when the bath temperature is the same, the temperature of the body is different between taking a bath with the body cold and taking a bath with the body cold. When bathing in a bathtub, it feels hot even if it is very lukewarm, and feels warm when bathing in an uncooled state.
[0006]
In the conventional bath apparatus, the cold state of the bather is not taken into consideration at all, and the bathing is performed immediately after detecting that a person has bathed in a uniform fixed pattern. The bath water temperature rises due to chasing before the body warms up sufficiently, causing the problem of forcing the bather to feel uncomfortable, and when taking a bath when the body is not cold, Even after the start of chasing, there is a problem that it feels uncomfortable as long as it feels slim for a long time.
[0007]
The present invention has been made to solve the above-described problems, and its purpose is to automatically determine the degree of cooling of the body of the bather based on the output information of the water level sensor when the person bathes in the bathtub.

[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention are described below with reference to the drawings. FIG. 1 shows a block configuration of a main part of an embodiment of a reheating control device for a bath according to the present invention, and FIGS. 2 and 3 show a schematic configuration of a bath having the control device of the present embodiment. It is shown.
[0014]
As shown in FIGS. 2 and 3, a bathtub 3 is connected to the bathtub 1 via external pipes 2 a and 2 b. A heating device 4 is accommodated in the bath 3, and the heating device 4 is configured to heat the reheating heat exchanger 6 with a burner 5.
[0015]
The gas passage 7 communicating with the burner 5 is provided with electromagnetic valves 8a and 8b for opening and closing the gas passage and a proportional valve 10 for controlling the gas supply amount to the burner 5 by the valve opening amount.
[0016]
A pipe 12 is connected between the inlet side of the reheating heat exchanger 6 and the discharge side of the circulation pump 11, and the suction side of the circulation pump 11 and the external pipe 2 a are connected by a return side pipe 13. Further, an outward pipe 14 is connected between the outlet side of the reheating heat exchanger 6 and the external pipe 2b, and these external pipe 2a, return side pipe 13, circulation pump 11, pipe 12, The passage leading to the bathtub 1 through the reheating heat exchanger 6, the outward pipe 14, and the external pipe 2 b in this order forms a recirculation circuit 15 for bath hot water.
[0017]
In the figure, 16 is a water level sensor composed of a pressure sensor for detecting the hot water level of the bathtub by water pressure, 17 is a water flow switch for detecting the flow of hot water, and 18 is the hot water temperature of the bathtub 1 as the bath temperature. A bath temperature sensor to be detected, 20 is a control device for controlling the reheating operation of the bath, and 21 is a remote controller provided with operation buttons, setting means for bath set temperature, and the like.
[0018]
The control device 20 controls the chasing operation as follows. For example, when the reheating operation is instructed by the remote controller 21 or in the operation state of the heat retaining mode, the circulation pump 11 is driven to circulate hot water in the bathtub 1 through the recirculation circuit 15. When the temperature detected by the bath temperature sensor 18 falls below the permissible range from the bath set temperature due to the circulation of the hot water, the electromagnetic valve 8a, 8b and the proportional valve 10 are opened, and the burner 5 is ignited by an unillustrated ignition means, and the circulating hot water is heated by the combustion heating power of the burner 5 when passing through the reheating heat exchanger 6, and reheating is performed. proceed. When the hot water temperature detected by the bath temperature sensor 18 reaches the bath set temperature, the circulation pump 11 is stopped, the combustion of the burner 5 is stopped, and the reheating is finished.
[0019]
What is characteristic in the present embodiment is that when a person takes a bath in the bathtub 1 during the heat retention mode operation, the coldness level of the bather is automatically detected, and the reheating pattern corresponding to the coldness level is detected. Therefore, the control device 20 is provided with a configuration for performing the follow-up operation.
[0020]
FIG. 1 shows the configuration of the essential parts of this unique control device 20, and a cooling degree determination part 22, a reheating control part 23, a cooling degree pattern data memory 24, a reheating pattern data memory 25, and And a timer 26 provided accordingly.
[0021]
The coldness pattern data memory 24 stores basic data for determining the coldness (cooling condition) of a person taking a bath. In this embodiment, the data for judging the degree of cooling is created based on the change pattern of the sensor output of the water level sensor 16. FIG. 4 shows a typical example of the cooling degree pattern for judging the cooling degree.
[0022]
(A) and (a ′) in FIG. 4 are data based on the temporal change rate of the water level sensor output, that is, the inclination of the sensor output rise accompanying the rise of the bath water level when the bather enters the bath. is there. When the degree of coldness of the body is small, the time from when the bather enters the bathtub until the water level is stabilized, for example, from the bath to the shoulder, is short, and therefore the slope α _S of the sensor output increase is large.
[0023]
On the other hand, when the bather's body is cold, the temperature of the body (the temperature felt by the body) increases even if the temperature of the bath is the same. Therefore, the slope α _G of increase in sensor output is small. Thus, the coldness degree of a bather's body can be judged from the inclination pattern of the rise of the sensor output from the bathing detection position where a person enters the bathtub and the bath water level starts to rise.
[0024]
When creating data for judging the degree of coldness based on this sensor output rise slope (tilt), the sensor output rise pattern data at the time of bathing in the bath was tested in each case when the coldness level of the body was small and large. Based on these experimental results, the optimum data of the sensor output increase slope when the degree of cooling is small and when the degree of cooling is small is created. For example, when the degree of cooling is small, the pattern data of FIG. When the degree of cooling is large, the pattern data (a ') in the figure is stored in the pattern data memory 24 as data for determining the degree of cooling. Actually, the upper and lower widths ± Δα _S and ± Δα _G are given to α _S that is judgment data with a low cooling degree and α _G that is judgment data with a high cooling degree, respectively, and the judgment data is α _S ± Δα _S , α _G ± Δα _G
[0025]
Also, as shown in FIGS. 4 (b) and 4 (b '), when the body temperature of the bather is small, the time until the water level stabilizes after bathing in the bath, for example, to the shoulder. t _S is shortened, and conversely, when the body is cold, the time t _G from entering the bathtub until the water level stabilizes becomes longer because the body is slowly bathed in the water at a slow speed. . Thus, it can employ | adopt as data which judge the coldness degree of a body by the time from the time of bathing detection to a bathtub (starting point where a bathtub water level rises) until a bather uses a hot water and a water level is stabilized. In this case as well, when the body is cold and when it is not cold, a bathing experiment is performed in the bathtub. The time t _S from the start of bathing to the stabilization of the water level when the degree of cooling is small, and the bathtub when the degree of cooling is large The optimum time t _G from the start of bathing to the stabilization of the water level is obtained, and ± Δt _S and ± Δt _G are added to these values, and the cooling degree pattern data is given as t _S ± Δt _S , t _G ± Δt _G Is stored in the cooling degree pattern data memory 24.
[0026]
Further, the degree of coldness of the bather's body can be determined based on a special sensor output pattern. For example, as shown in FIG. 4 (c), when the coldness of the bather's body is small, the bather smoothly enters the bathtub and uses the hot water, but when the coldness of the body is large, For example, there is a case where the user feels hot as soon as one foot is first placed in the bathtub, and the foot is retracted. In this case, a special sensor output pattern as shown by an arrow A in FIG. .
[0027]
When judging the degree of cooling based on such a special pattern of sensor output, a pattern in which no special pattern as shown in FIG. 4C is generated is used as pattern data when the degree of cooling is small, and FIG. The case where various special patterns as shown in (c ′) of FIG. 5 are generated is stored in the cooling degree pattern data memory 24 as pattern data having a high cooling degree. Any one of the data of the groups (a) and (a ') in FIG. 4, the data of the groups (b) and (b'), and the data of the groups (c) and (c '). However, in order to more accurately determine the degree of coldness of the bather, two or more groups of data (more preferably, all groups of data) are stored in the memory 24. To store.
[0028]
The cooling degree determination unit 22 takes in the sensor output from the water level sensor 16, detects a person bathing in the bathtub when the sensor output starts increasing, and the detection pattern of the water level sensor 16 is stored in the cooling degree pattern data memory 24. Compared with the coldness pattern data, it is determined whether the coldness of the bather's body is small or large. For example, if the sensor output pattern of the water level sensor 16 is included in the inclination range (α _S ± Δα _S ) of the sensor output increase as shown in FIG. 4A, it is determined that the degree of cooling is small. If it is included in the rising slope range (α _G ± Δα _G ) of the sensor output as shown in (a ′) of FIG.
[0029]
In addition, when the degree of cooling is determined by the time from when the bather starts entering the bathtub until the water level is stabilized, the cooling degree determination unit 22 sets the timer 26 when the bathing is detected due to an increase in sensor output. Operate and measure the time until the water level stabilizes. The measured time is compared with the data stored in the cooling degree pattern data memory 24. For example, if the time is within the range of t _s ± Δt _S as shown in FIG. Is determined to be small, and when the time is within the range of t _G ± Δt _G , the degree of cooling is determined to be large.
[0030]
Further, when determining the degree of cooling of the body based on whether or not a special pattern is generated in the water level sensor output, the sensor output pattern of the water level sensor 16 includes, for example, a special pattern A as shown in FIG. If this happens, it is judged that the bather is cold.
[0031]
The determination of the cooling degree is made up of the groups shown in (a) and (a ′) of FIG. 4, the groups shown in (b) and (b ′), and the groups shown in (c) and (c ′). Although the degree of coldness of the body may be determined based on the pattern data of any one group, in order to make the determination more accurately, data of two or more groups (more preferably, data of all groups) are used. Make a comprehensive decision as a decision target.
[0032]
The chasing pattern data memory 25 stores chasing pattern data corresponding to the coldness of the bather's body.
[0033]
FIG. 5 shows examples of various reheating patterns when the cooling degree is small and large. (A) and (a ') of the figure are reheating pattern data based on the amount of heat per unit time of reheating (burning heat amount of the burner 5 per unit time), and (a) of the figure is bathing. The reheating pattern when the amount of heat per unit time of reheating that starts after detection is increased and the refrigerating degree is small is shown. (A ′) in FIG. This is a reheating pattern in a case where the degree of cooling for performing reheating by reducing the amount of heat per hour is large. If the bather's cold level is small, he will not feel hot even if he starts chasing with a large amount of heat, but if the cold level is large, he will feel hot when he starts chasing with a large amount of heat. It is intended to whisper.
[0034]
(B) and (b ′) in FIG. 5 show a rebirth that distinguishes a rebirth form between a case where the degree of cooling is small and a case where it is large depending on the total amount of heating during a rebirth period after the rebate starts. Pattern data. This is because if the body of the bather is cold, it will not feel particularly hot even if it is reheated with a large total heat, and if the body is cold, it will be reheated with a large total heat. Because it feels hot when you do it, you try to catch up with a small total heat.
[0035]
The data shown in (c) and (c ′) of FIG. 5 is data for discriminating the chasing pattern according to the chasing start waiting time from when bathing is detected until chasing is started. If the temperature of the bather is small, the body will adjust to the bath temperature in a short time after bathing detection, so if you start chasing after a short time after bathing detection, you will not feel hot and start chasing after bathing detection If the time until the time is long, there is a problem that it feels slim before retreating. In order to solve such a problem, when the degree of cooling is small, retreat is started within a short time after detection of bathing. (C) retrace pattern data is provided. Also, if the bather is cold, it will feel hot if you start chasing immediately after bathing detection.To avoid this, take a relatively long time until the body adjusts to the bath temperature after bathing detection. The pattern shown in FIG. 5 (c ′), which starts reheating after that, is given as reheating pattern data when the degree of cooling is large.
[0036]
Further, as shown in (d) and (d ′) of FIG. 5, when the bather's cooling degree is small, it is given as continuous driving retreat pattern data, and when the cooling degree is large, intermittent reheating operation data is given. Can also be given. If the bather is cold, it feels hot when chasing continuously, so chasing is intermittently performed to gradually adjust the bather to the set temperature of the bath. Further, as shown in (e) and (e ′) of FIG. 5, the time per one time of intermittent chasing may be changed. Although not shown in the figure, the times per (e) and (e ′) may be made the same by changing the times per one time.
[0037]
The tracking pattern data of each group is given in an appropriate form such as graph data, table data, arithmetic expression data, etc., for example, when giving stepless control data according to the cooling condition in the arithmetic expression data, In the groups (a) and (a ′) of FIG. 5, the amount of heat per unit time is given as a function f (P / t) of the change value per unit time t of the water level sensor output P according to the coldness of the bather. It is done. Similarly, in the data of the groups (b) and (b ′) in FIG. 5, the total amount of heat given to the bathtub hot water according to the degree of cooling is given as a function of h (P / t). Moreover, it does not matter even if it changes into a total calorie | heat amount and is a bath water temperature.
[0038]
In the data of the groups (c) and (c ′) in FIG. 5, the waiting time until the start of reheating is given as a function of g (P / t) according to the degree of cooling.
[0039]
The retrace pattern data memory 25 includes one of the groups (a), (a ′) and (b), (b ′) and (c), (c ′), (d), and (d ′). Although it may be given as data, two or more data parameters of each of these groups may be combined to create rework pattern data corresponding to the cooling degree, and this may be stored in the retreat pattern data memory 25 .
[0040]
The chasing control unit 23 stores chasing pattern data corresponding to the bather's cold degree in the chasing pattern data memory 25 based on the bather's cold degree determination information determined by the coldness degree determining unit 22. The driver selects one of the various repelling pattern data, and controls the repulsive operation based on the selected repelling pattern data. For example, when the data (a) or (a ′) in FIG. 5 is selected, the power applied to the proportional valve 10 according to the amount of reheating heat per unit time (the valve opening amount of the proportional valve 10 is the amount of applied power). (Proportional to the size), or the amount of rotation of the circulation pump 11 (the flow rate of the circulating hot water), or both. Further, in the control based on the reheating pattern data of the groups (b) and (b ′) in FIG. 5, the size of the area obtained by multiplying the heat amount per unit time of reheating by the continuous supply time of the heat amount is shown. The time and / or amount of heat is controlled so that the total amount of heat given in (b) or (b ′) of 5 is reached.
[0041]
Further, in the case of the control by the tracking pattern data of the groups (c) and (c ′) shown in FIG. 5, the timer time is instructed to the timer 26, and when the bathing is detected according to the coldness level of the bather. Controls the waiting time from the start to the start of chasing. Furthermore, in the case of controlling the reheating operation based on the pattern data of the operation mode shown in (d) and (d ′) of FIG. 5, the reheating heat amount is continuously added when the coldness level of the bather is small. The chasing operation is controlled by continuous operation, and when the degree of cooling is large, the chasing operation is controlled by intermittent operation based on the data given by (d ′) in FIG. When the data of each group is used as a parameter and the data of two or more groups is combined and the reheating pattern data for the case of low and high cooling is given, the control form corresponding to that is followed. Control whispering. Further, in (e) and (e ′) shown in FIG. 5, the time and / or the number of intermittent operations are controlled.
[0042]
According to the present embodiment, when a person bathes in a bathtub in the operation state of the heat retention mode, the cooling degree (cooling degree) of the person's body is determined by the instrument itself based on the detection output of the water level sensor, and the bathing is performed. The appropriate chasing pattern data corresponding to the person's cold state is selected, and chasing is performed according to the data, so that the bather does not feel uncomfortable by feeling warm or hot, Since the chasing is performed so as to adjust to the sensible temperature suitable for the cooling condition, it is possible to achieve an epoch-making effect that the bath water temperature can be raised to the bath set temperature in a comfortable bathing state.
[0043]
In addition, the selection of the chasing pattern data suitable for these bathers is done automatically by the equipment itself without any trouble of the buttons being operated by the bather, so it is easy to use and provides a comfortable bath environment for the user. It becomes possible to provide.
[0044]
In addition, this invention is not limited to the said embodiment example, Various embodiment can be taken. For example, in the above-described embodiment, a bath pot that forcibly circulates bath water using the circulation pump 11 has been described. However, the embodiment is applied as a recirculation control device for a natural circulation bath that does not use the circulation pump 11. It is also possible. For example, as shown in FIG. 6, the natural circulation type bath pot is supplied with air (air) into the bathtub 1 from the outside using a hose or the like after being reheated. There are types that stir hot water, and types that, as shown in FIG. 7, drop hot water produced by a heat exchanger by burner heating into the bathtub 1 and reheat with hot hot water. The present invention can also be applied to a type of instrument.
[0045]
Further, in the above-described embodiment, the description has been given for the bath pot having only the reheating function, but, for example, the reheating circulation path of the bath and the hot water supply pipe of the water heater are connected by a hot water filled passage with a pouring valve. It can also be applied as a reheating control device for a hot water bath with a hot water filling function that can fill the bathtub from the hot water supply side through the hot water filling passage and the reheating circulation passage. It can be applied as a reheating control device for various types of bath pots.
[0046]
Furthermore, in the above embodiment, an example in which the bather's coldness level is continuously determined has been shown, but it may be divided into two types, large and small, or large, medium, and small. Furthermore, it may be subdivided into four or more sections. As described above, even when the cooling degree is divided into three or more, the cooling degree pattern data for distinguishing and determining the divided cooling degrees is stored in the cooling degree pattern data memory 24, and the subdivided cooling degree data is stored. The tracking pattern data corresponding to the classification is stored in the tracking pattern data memory 25. By subdividing the bather's cooling degree in this way, it becomes possible to select more detailed reheating pattern data that matches the cooling degree of the bather and to perform more comfortable reheating combustion operation. In the embodiment, the reheating pattern in the case where the temperature of the bathtub hot water is lower than the bath set temperature has been described. However, the present invention is not limited to this. It doesn't matter. Further, it may be a constant amount of heat instead of a constant temperature, or may be manually turned off (OFF) as a continuous chasing.
[0047]
【The invention's effect】
The present invention automatically determines the cooling level of a person who has bathed in a bathtub using the detection output of a water level sensor that detects the bathtub water level, and the reheating pattern data suitable for the cooling level (cooling level) of the bather Since the bather is configured to control the chasing operation based on the data, the bather feels hot and slim and feels comfortable with the cold temperature of his / her body. As a result of the retreating by the retreating pattern, it is possible to achieve an epoch-making effect that it is possible to retreat the bath water to the bath set temperature in a comfortable bathing state.
[0048]
In addition, the selection of the chase pattern data according to the coldness of the bather's body is performed without the trouble of the button being operated by the bather, and the appliance itself automatically determines the coldness of the bather's body. Since it is a thing, it becomes very convenient and it becomes possible to provide a user with a comfortable bath environment.
