Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat storage type or non-heat storage type floor heating control method.

[0002]

2. Description of the Related Art In a conventional temperature control method for a floor heating system, as shown in Japanese Patent Application Laid-Open No. 4-15420 as an example of heat storage type floor heating, a temperature detecting place where a sensor is installed to obtain temperature information is a floor finishing material. (The following is referred to as the underfloor material), the vicinity of the floor near the heat storage material, and the indoor air temperature are generally performed in two places to obtain a comfortable heating environment.

When nothing is placed on the floor surface, comfortable temperature control can be performed by the floor surface temperature and the room air temperature as described above. However, the floor surface temperature including the underfloor material is detected on the floor surface. Since the whole is a moving living space for human beings, things such as rugs such as furniture and carpets as well as human beings were placed on the detection place and blocked, that is, heat radiation from the floor surface was obstructed. It often goes into a state. If it is blocked and heat dissipation is disturbed, the temperature of that part naturally rises, and the sensor installed at the detection location cannot detect normal temperature as the entire floor heating system. That is, in the case of the heat storage type floor heating, while the heat storage is energized, the temperature information becomes erroneous as if the heat storage was completed earlier, and the heat storage becomes insufficient. In the case of non-heat storage type floor heating, the temperature control mechanism operates due to incorrect temperature information even if the floor surface temperature other than the closed part has not reached the specified value. It may not be.

[0004]

As described above, conventionally, in the comfortable temperature control of the whole room by the floor heating, the floor temperature detection method and the numerical processing method based on the temperature information are not appropriate. There was a problem.

In view of the above problems, it is an object of the present invention to make it difficult for the floor surface at the temperature detection position where the sensor is installed to be closed, and to enable proper temperature control even if it is closed. .

[0006]

[Means for Solving the Problems] In order to solve the above-mentioned problems, a floor temperature sensor provided in a lower floor material for arranging a heat storage material and a heating element under the floor surface, and a wall surface remote from the floor surface are provided. Equipped with a wall temperature sensor and a controller body that controls based on temperature information from both the floor temperature sensor and the wall temperature sensor. When the temperature detection range of the floor temperature sensor is blocked, the floor surface temperature is converted. The value below the temperature that does not cause human injury such as low temperature burns and the heat resistance limit temperature of each member of the underfloor material such as heat storage material, and further exceeds the preset condition range. Exclude erroneous temperature information on the heating side of the underfloor to be placed, and only the temperature information on the heating side of the underfloor that places the heating element in the proper range and the temperature information on the wall surface on the heating side, Heat storage energization and general energization during the daytime It was assumed to continue.

Further, on the heat generating side of the underfloor material on which the heating element is arranged, a floor temperature sensor is installed on the floor surface or under the underfloor material, and the temperature detection range is clearly indicated on the floor surface immediately above the floor temperature sensor. In addition to providing the temperature detection position part, on the wall surface on the heating side away from the floor surface,
The wall temperature sensor is provided at a position corresponding to the wall surface including the indoor space and the ceiling surface.

Further, in the controller body which controls based on the temperature information from both the floor temperature sensor and the wall temperature sensor,
For the control, the condition to be newly predicted and set is set to a constant temperature range or a constant temperature rising rate range.

Further, when erroneous temperature information on the heat generating side of the underfloor material on which the heating element is arranged is excluded, the user can recognize the abnormal state of temperature detection of the floor surface so that the controller main body can display an indicator light or a notification unit. It is supposed to be notified by a notification sound.

Further, the floor temperature sensor installation site on the heat generation side of the underfloor material for arranging the heating element is made to be able to change the control set temperature of the controller body, and the underfloor material / heat storage which is each member under the underfloor material. The back surface of the material / heating element, the floor surface, or a part having a combination of them can be selected.

Radiation heat from the wall surface including the ceiling surface, the indoor space, the floor surface which is the heat generating side such as the panel surface of the main body of the wall mounting controller, etc. In addition, the control set temperature of the controller body that receives the temperature information from the wall temperature sensor can be changed.

Further, the range of the temperature detection position portion provided on the floor surface is a means which does not easily disappear, and the light emitting display means having excellent visibility and long life is embedded in the underfloor material on the same plane as the floor surface. .

[0013]

Function: By clearly indicating the temperature detection range of the sensor on the floor by means that cannot be easily erased by anyone, the resident does not put furniture or rugs on the temperature detection range.

Further, even if the temperature detection range part is blocked, proper control can be performed by the temperature information of the sensor on the heat collecting side. Therefore, in the case of the heat storage type floor heating, proper heat storage can be continued while the heat storage is energized. In the case of non-heat storage type floor heating, the comfortable environment in the room, which is set in advance by the temperature information from the sensor provided on the heating side, is maintained, so heating does not become insufficient.

Further, when the temperature detection range is closed and an abnormal temperature is detected, the removal of the blockage is speeded up by the display notification of the controller or the like, and proper temperature control can be continued.

Further, an indicator lamp 17 and a notification unit 18 are provided on the surface of the controller body 7. Although not shown in FIG. 3, safety devices such as an earth leakage breaker and an overcurrent breaker are provided in the power supply circuit as needed.

That is, although the underfloor material 1 is a wooden floor finish material generally used for houses in this embodiment, it is not limited to wood. The underfloor material 2 specifically refers to the back surface of the underfloor material 1, the heat storage material 8, the heating element 9, the space between them, and the like.

The floor temperature sensor 3 is a place which is not affected by heat from the sun such as solar radiation, heat generating equipment, housework, etc.
The floor surface 1a, the back surface portion 3a of the underfloor material 2, the heat storage material 8 portion 3b, the heating element 9 portion 3c, or the like can be provided on the respective surfaces or side surfaces thereof or collectively.

To do. In this embodiment, the case of the floor surface 1a will be described.

The temperature detecting position portion 5 displays the detection range of the floor surface temperature of the floor temperature sensor 3 on the floor surface 1a by means that cannot be easily erased. For example, it is possible to embed a light emitting display means such as a light emitting diode having excellent visibility and life on the floor surface 1a in the underfloor material 1 (not shown), or to inspect a sensor or the like in consideration of serviceability. , There is a form such as an attachment frame of an underfloor storage or a floor-embedded power outlet and its opening / closing mechanism.

Similar to the floor temperature sensor 3, the wall temperature sensor 6 is provided on each of the wall surfaces 14a and the like including the ceiling surface 15a or collectively in a place not affected by other heat. However, the wall temperature sensor 6 is provided at a place that is equivalent to the wall temperature away from the wall surface 14a unless it is greatly affected by the indoor air.

The controller main body 7 is provided at a position where a resident can easily operate it and can easily see the display. When the surface temperature of the controller body 7 shows a tendency equivalent to the wall surface temperature, the wall temperature sensor 6 is provided on the surface of the controller body 7.

Further, since the temperature information from the floor temperature sensor 3 and the wall temperature sensor 6 varies depending on the characteristics of the respective sensors, the installation site, etc., or the floor heating system scale, etc., it can be changed by a switch or a program of a microcomputer. Be prepared to respond.

Further, as shown in FIG. 3, in the case where the control relay box 19 for supplying the power source 20 to the heating element 9 is not built in the controller body 7 but separated according to the scale of the floor heating system. There is also.

The heat storage material 8 is provided between the joists 11 of the underfloor material 2 and at a position where it is heated by the heating element 9. The volume of the heat storage material 8 can be changed according to the required heat storage amount, or the heat storage material 8 can be provided below the heating element 9. Even in the case of a site-installed heat storage material such as concrete without joists 11, the amount of heat storage material is appropriately adjusted according to the entire system.

The heating element 9 has a surrounding electrically insulated
Similar to the heat storage material 8, the heat storage material 8 is provided between the joists 11 of the underfloor material 2 to heat the heat storage material 8. The heating element 9 referred to here includes not only a heating element but also a panel-like unit integrated with the heat storage material 8 and the heat insulating material 10a. In the non-heat storage type floor heating without the heat storage material 8, the heating element 9 is used to heat directly from the rear surface of the underfloor material 1.

As the heat insulating material 10a, a material having a low thermal conductivity is selected in order to withstand the temperature and load of the heat generating element 9 and the heat storage material 8 placed thereon and improve the heating efficiency. Insulation 1
In order to improve the heating efficiency even for 0b, a material with a small heat transmission coefficient from the indoor side to the outdoor side is selected comprehensively, including the difficulty of construction management.

The joists 11 fix the underfloor material 1 at the upper part,
The side part accommodates the heat storage material 8, the heating element 9, and the heat insulating material 10a between the joist material 11 provided adjacently. The height of the joist 11 is appropriately determined according to the specifications of the floor heating system to be installed.

Support material 1 for supporting the underfloor heating system from below the floor
2. The construction material is generally undertaken by the construction worker for the large drawing material 13 according to the specified specifications of the floor heating system, but the floor is sufficiently insulated to minimize the radiation of the floor heating from under the floor.

In the case of a general house, the side wall material 14 is a non-combustible material typified by gypsum board and has a decorative wallpaper on its surface. The ceiling material 15 is the same as the side wall material 14, but in many cases, a gypsum board is double-bonded to ensure a noncombustible partition with the second floor.

In the case of radiant heating type floor heating, the air existing in the indoor space 16 is not a direct heat medium for a warmer like a convection type heater, but the floor surface 1a and the wall surface 14 are
a, it is heated by thermal contact with the ceiling surface 15a and becomes one of the heating elements as convection heat.

The indicator lamp 17 and the notification unit 18 notify the warmer of the abnormality by light, sound, or the like when the temperature detection abnormality occurs such as when the temperature detection position portion 5 of the floor surface 1a is closed.

The relay box 19 controls the heating element 9 by a signal from the controller body 7 as necessary, such as when the floor heating system has a large scale and the control output in the controller body 7 is insufficient. Power source 20 is generally an alternating current
Power is supplied to the heating element 9, the controller body 7, and the relay box 19 at 100V or 200V.

In the temperature control circuit basic system diagram of FIG.
The controller main body 7, which is provided with a display unit 17 (not shown) such as a clock and a timer, and a display unit such as a clock and a timer, as a heat generating side, is used as a floor temperature sensor 3 and a warming side to obtain temperature information. The number of wall temperature sensors 6 is connected according to the scale of the floor heating system. Further, the controller body 7 is connected to a relay box 19 that controls the heating element 9. The controller body 7 and the relay box 19 are connected to the power source 20, but the power supply to the relay box 19 is performed by the controller body 7.
There is also a way through. Further, for a system having a small scale, the function of the relay box 19 can be built in the controller body 7.

Next, the operation of the above configuration will be described.

In the floor heating control method of the present invention, the temperature control temperature detecting sections are roughly divided into two locations. One of them is a floor, and the other is a wall. As for the floor, the floor surface 1a is specifically provided as a place where the detection unit can be provided, and the heat storage material 8 and the underfloor material 2 of the heating element 9 are also provided. It was possible to change the set control temperature.

From the heating element 9 to the floor surface 1a, it is a heating source when viewed from the entire room where the warmer is present.
For the sake of explanation, they are collectively referred to as the "heat generating side". Also, the wall surface 14a in the room away from the floor surface 1a with respect to the heat generating side,
Since the ceiling surface 15a, the indoor space 16 and the like are on the heated side where there are warmers, they are collectively referred to as the "warming side" for the sake of explanation. In an actual system, the temperature detection locations on the heat generation side and the heat collection side and the number thereof are appropriately selected depending on the scale and the like.

In order to maintain proper temperature control, the present invention adopts a method as shown in FIG. 1 that it can be adhered to by a user of floor heating. That is, by displaying the range of the temperature detection position portion 5 provided with the floor temperature sensor 3 clearly and easily by means that does not disappear, the floor heating user is less likely to be in the detection range or place an article or the like. Therefore, the temperature control is properly performed.

Further, when the light emitting display element is embedded in the underfloor member 1, the floor surface 1a displays the temperature detection position portion 5 even in a dark room such as at night so that it is extremely clear including the operating condition of the floor heating. Is displayed.

Next, the operation of the temperature control circuit will be described with reference to the temperature control circuit basic system diagram of FIG. 3 and the graphs of FIGS. 4 and 5.

In a normal state in which the temperature detecting position 5 on the floor surface 1a is not closed, temperature information from both the floor temperature sensor 3 and the wall temperature sensor 6 is taken in, and the controller main body 7 with a built-in microcomputer follows a program. And perform appropriate numerical control to perform normal proper temperature control.

That is, as shown in FIG. 4, the correlation between the wall temperature (Tw) and the floor temperature (Tf) in the room is obtained beforehand by experiments or the like on the basis of the comfortable temperature condition, and the temperature control requirement is set in the program. I'll do it. For example, in FIG. 4, when the wall or ceiling temperature Tw is 15 ° C., the floor surface temperature Tf is controlled to be about 24 ° C. Similarly, when Tw is 19 ° C., the temperature is controlled so that Tf is also about 19 ° C.
It should be noted that the comfortable temperature condition may vary depending on the region or individual, so it is preferable that the warmer can adjust the control temperature range to some extent.

Next, the temperature rise characteristics including the time element after energization as shown in FIG. 5 are also controlled while monitoring whether they are within the preset characteristic value range. Particularly in the case of the heat storage type floor heating system, the residual heat amount of the heat storage material 8 depends on the environmental conditions inside and outside the room even if the floor surface 1a is not blocked, and therefore the temperature of the floor surface 1a must be constantly monitored to prevent excessive heat storage. There will be a shortage.

That is, when the rate of temperature rise after energization is faster than the set value, it is assumed that there is a large amount of residual heat of the heat storage material 8, that is, the amount of heat that has already been stored. Proper heat storage control of the material 8 is performed, and temperature control is performed so that the heat resistant temperatures of other members can be observed.

It should be noted that the rate of rapid temperature rise due to the large amount of residual heat of the heat storage material 8 in the state where the floor surface 1a is not blocked is slower than when the floor surface 1a is blocked, so it is blocked. It can be determined that the temperature has risen.

On the contrary, when the rate of temperature rise after energization is slower than the set value, it is assumed that the residual heat amount of the heat storage material 8 is small, so that the energization time to the heating element 9 is lengthened or the system is operated. Alternatively, if the heating element can increase the heating value, the heating value is increased.

On the other hand, when the temperature detection position portion 5 of the floor surface 1a is partially closed and in an abnormal state, the temperature information detected by the floor temperature sensor 3 is the temperature information at the time of saturation or in the case of the heat storage type floor heating system. At the time of heat radiation, the heat storage material 8 serves as a heat source and shows a rapid temperature rise.

Therefore, when the rapid temperature rising rate and the temperature itself deviate from the preset characteristic values, the temperature information detected by the floor temperature sensor 3 is judged to be abnormal and is not taken as a numerical value for temperature control in the program. To

The previously set characteristic value is
The temperature conversion value of the floor surface 1a is below a temperature at which human body is not harmed by low-temperature burns, and below a heat resistance limit temperature equivalent value of a member such as the heat storage material 8.

When a plurality of temperature detecting position portions 5 on the floor surface 1a are provided, the temperature information of the other unclosed temperature detecting positions is fetched, but one or a plurality of temperature detecting position portions 5 are provided. When the temperature detection position portion 5 is closed, the temperature information of the wall temperature sensor 6 on the heating side is used to determine the heating status of the entire room and control the temperature.

Here, when the temperature information from the floor temperature sensor 3 is ignored, there is a possibility that the temperature may be slightly deviated from the optimum temperature control range by the combined temperature control with the wall temperature sensor 6.
This is a highly practical system as compared to a control system in which energization is stopped based on temperature information from the floor temperature sensor 3.

FIG. 6 shows an example of a control flow chart when the temperature control of the present invention is applied to the heat storage type floor heating with an additional heating function.

That is, when heat is stored when the power is on,
In the heat storage time zone, floor temperature (Tf) and wall temperature (Tf)
According to w), the relay is turned on under the on condition, and the relay is turned off under the off condition, and the temperature control is continued until the heat is dissipated.
Regarding the on condition and the off condition, FIG. 4 and FIG.
The characteristics such as the above are inputted in a program in advance, and used as a criterion for correctness of the temperature information from the floor temperature sensor 3 when the temperature detection position portion 5 of the floor surface 1a is closed.

Next, at the time of heat dissipation after the end of heat storage, if the additional heating key is on, the relay is turned on if the ON condition is satisfied by the floor surface temperature (Tf) and the wall surface temperature (Tw) as in the case of heat storage.
If it is an off condition, the relay is turned off and temperature control during reheating is continued until the heat radiation time period ends. The operation under the ON condition and the OFF condition is almost the same as that during heat storage,
The difference is that the heat storage material 8 is already warmed during heat dissipation, so during heating, there is no long-time energization from the beginning of energization as shown in Fig. 5, and the room is comfortable due to the temperature drop process during heat dissipation. In order to maintain the environment, it is necessary to make the setting of the floor temperature (Tf) and the wall surface temperature (Tw) for the on condition and the off condition more detailed.

Although the criteria for determining whether the temperature information from the floor temperature sensor 3 is correct or not are almost the same as in the case of heat storage, the floor surface 1a is radiated only by the heat storage material 8 at the time of heat radiation without additional heating. Since it is heated, the temperature rises when the floor surface 1a is closed, but in this case, although it cannot be involved in electrical control, it does not exceed the control temperature during heat storage, so there is very little problem in heating.

[0061]

As described above, according to the present invention, it is possible to perform proper floor heating control for the entire room by excluding erroneous temperature information generated due to the blockage of the floor surface and controlling the temperature. By clearly indicating the temperature detection position part and its range, the floor temperature sensor part by a person or an article is less likely to be blocked.

Further, since the temperature control is based on a constant temperature range and a temperature rising rate, a comfortable floor heating environment can always be obtained.

Further, since the abnormal temperature detection condition of the floor surface is notified to the warmer by the alarm light from the indicator light of the controller main body or the alarm unit, the use in the normal condition is increased, and more comfortable floor heating control is continued. Will be possible.

On the other hand, since the installation position of the floor temperature sensor can be freely selected, the design and construction according to the floor heating system scale and type can be facilitated, and more comfortable temperature control can be performed.

Further, by using the light emitting display means embedded in the underfloor material as the method of clearly indicating the temperature detection position portion on the floor surface, the temperature detection position portion is less likely to be blocked during use of floor heating even in a dark place such as at night. , Which made it possible to continue more comfortable temperature control.
