Description

  The present invention relates to a floor warm carpet.

  Conventionally, a floor surface hot water heating apparatus (for example, refer to Patent Document 1) has a hot water pipe installed under a floor surface in the room, and hot water heated by a hot water source such as gas, electricity, or heat pump is supplied to the hot water pipe. By supplying, the floor is directly heated.

  When using this floor surface hot water heating device, for example, the user may place a chair on the floor surface, sit on the chair, and heat the feet with the back of the foot resting on the floor surface. A carpet may be laid on the top and warmed in a posture where the lower body is placed on the carpet.

  This floor hot water heating device requires a hot water supply heat source, a hot water pipe, and the like, and the hot water pipe must be installed below the floor surface. Therefore, installation in an existing building requires labor and cost. Therefore, the floor hot water heater is often installed mainly when a building is newly constructed.

  On the other hand, carpets are laid on the floor surface of the room and are classified as so-called electric carpets that can be heated relatively easily by energizing a heating element that generates heat due to Joule heat disposed inside. A warm floor carpet (for example, Non-Patent Document 1) is also known.

  This floor warm carpet is different from a carpet-type electric carpet that is used with a cover woven with fibers, and is configured to be laid directly on the floor without using the cover and to be easily used. Has been. For example, the warm floor carpet has a surface material (a member touching the user's body) similar to the woody tone of the indoor floor surface, and is made of a smooth material that does not allow water to pass through. The floor warming carpet is used in such a usage form that a user places a table or chair on the surface material, sits on the chair, and heats the feet around the surface in a posture where the back of the foot is placed on the surface material. ing.

  In addition, the floor warming carpet is not only a smooth material that does not allow water to pass through, but the floor warming carpet sinks slightly toward the floor when the body is placed on it, so that it recovers when the load on the body disappears. Material. For this reason, the floor warm carpet is not only used in a manner in which the user sits on a chair and places his feet on the surface material as described above, and heats the feet around the feet, but also the user has at least the back of the feet. It can also be used for usage in which the lower body other than the above is warmed in a posture where it is placed on the surface material.

2007 / Electric carpets listed in pages 5 to 16 of the electric heating general catalog (as of September 1, 2007, Matsushita Electric Industrial Co., Ltd.)

However, in the above conventional warm floor carpet, even if the posture when the user warms is changed, the discomfort given to the user according to the change in the posture (change in use form) is sufficient. However, there is still room for improvement from the viewpoint of performing appropriate temperature control of the surface material so that heating can be performed in a reduced state.

  That is, the above conventional floor warming carpet is used when the user warms up with the posture that the back of the foot is placed on the surface material by sitting on a chair (hereinafter referred to as “first warming”). Emphasizing that sufficient temperature can be obtained even if the body is warmed in a very narrow area of the body of the back, the set temperature of the surface material at the time of this first warming, "the user is at least other than the back of the foot In general, the temperature control should be performed at a slightly higher temperature than the set temperature of the surface material when the lower body is warmed with the posture placed on the surface material (hereinafter referred to as “second warming”). Was composed.

  In other words, the conventional floor warm carpet is designed on the assumption that the user uses the posture at the time of the first warming, and the temperature of the first warming is higher than the set temperature of the surface material in the posture of the second warming. In addition to warming by raising the set temperature of the surface material in the posture and directly touching the surface material, even if the body is not directly touching the surface material, the user will be sufficiently exposed to radiation heat from the floor warm carpet. It was designed to give you a sense of warmth.

  However, as a result of the survey on the actual use of the floor warming carpet users by the present inventors, the user is using the floor warming carpet in the second warming posture rather than the first warming posture. I found many.

  For this reason, when the user moves from the posture at the time of the first warming to the posture at the time of the second warming and tries to warm up, the user feels the uncomfortable feeling of being hot when warming in the posture at the time of the second warming. There was a fear.

  In addition, when the user feels hot during the second warming, it is only necessary to adjust the amount of current supplied to the heating element to lower the temperature of the surface material, but a predetermined time is required to lower the temperature of the surface material. Therefore, it takes time for the user to feel comfortable warmth after lowering the temperature of the surface material. Therefore, after adjusting the temperature of the surface material, if the temperature of the surface material is not appropriate for the user, there is a need to adjust the temperature again in addition to the waiting time for the inevitable temperature change described above. Accordingly, there is a possibility that the user may amplify the uncomfortable feeling that the user is unsatisfactory, and there is room for improvement from the viewpoint of sufficiently reducing the unpleasant feeling given to the user.

  The present invention has been made in view of the above-described problems of the prior art, and even when the user changes the posture when warming, the posture is changed (change in use form). An object of the present invention is to provide a floor warming carpet capable of appropriately controlling the temperature of a surface material so that warming can be performed in a state where discomfort given to a user is sufficiently reduced.

In order to solve the above-described problems of the prior art, the present invention provides:
A floor warm carpet used on the floor surface,
A curtain-like base material that can be wound and folded;
A surface material covering a surface facing the user of the two main surfaces of the substrate;

At the time of the second warming in which the user warms at least the lower body other than the back of the foot on the surface material, the set temperature Ts of the surface material is set to a temperature Ts2 lower than the temperature Ts1 at the time of the first warming. A temperature conservative setting means for setting according to the user's request; and
Connected to the heating element, temperature detection means, temperature setting means, and temperature moderation setting means, receives a temperature control signal transmitted from either the temperature setting means or the temperature moderation setting means, The temperature of the heating element detected by the temperature detecting means so that the actual surface temperature Tsr approaches the set temperature Ts set by the user's request using either the temperature setting means or the temperature conservative setting means. Temperature control means for controlling energization to the heating element based on Th;
Having
A floor warm carpet is provided.

  Here, in the present invention, the temperature Ts1 at the time of the first warming is higher than that at the time of the second warming, and from the following temperature range between the “lower limit value A” and the “upper limit value A”. This is a predetermined “set temperature value A” to be selected.

  That is, the temperature that the user feels in the first warming posture is “when the temperature rises from the temperature range where it feels cold to the temperature range where it feels warm (or from the temperature range where it feels warm to the temperature range where it feels cold” In this case, the boundary value between the temperature range in which the user feels cold and the temperature range in which the user feels not cool is set as the “lower limit value A”, and the temperature range where the user feels hot from the temperature range where the user feels warm The boundary value between the temperature range that the user feels warm and the temperature range that the user feels hot when the temperature rises to (or the temperature drops from a temperature range that feels hot to a temperature range that feels warm) ”Is an“ upper limit value A ”, and is a set temperature value A determined from a temperature range in which the temperature is felt to be warm from the“ lower limit value A ”to the“ upper limit value A ”.

  These “lower limit value A”, “upper limit value A”, and “temperature Ts1” are the usage environment of the floor warm carpet of the present invention {the daily change in the average temperature at the installation site, the annual (season) of the average temperature described above. Change, daily change in average humidity at the installation location, annual (seasonal) change in the above average humidity, user information (number of users sharing the floor warm carpet of the present invention, age distribution, Gender distribution, body fat percentage distribution, weight distribution, etc.), etc.} can be determined in advance by experiments or simulations so as to be suitable for use in the first warming posture.

  In the present invention, the temperature Ts2 at the second warming is lower than the temperature at the first warming and is selected from the following temperature range between the “lower limit B” and the “upper limit B”. This is a predetermined “set temperature value B”.

  That is, the temperature that the user feels in the second warming posture is “when the temperature rises from a temperature range where it feels cold to a temperature range where it feels warm (or from a temperature range where it feels warm to a temperature range where it feels cold” In this case, the boundary value between the temperature range in which the user feels cold and the temperature range in which the user feels not cool is set as the “lower limit value B”, and the temperature range where the temperature feels hot from the temperature range where the user feels warm The boundary value between the temperature range that the user feels warm and the temperature range that the user feels hot when the temperature rises to (or the temperature drops from a temperature range that feels hot to a temperature range that feels warm) ”Is an“ upper limit value B ”, and is a set temperature value B determined from a temperature range that is felt to be warm from the“ lower limit value B ”to the“ upper limit value B ”.

  These “lower limit value B”, “upper limit value B”, and “temperature Ts2” are the usage environment of the floor warm carpet of the present invention {the daily change of the average temperature at the installation site, the annual (season) of the average temperature. Change, daily change in average humidity at the installation location, annual (seasonal) change in the above average humidity, user information (number of users sharing the floor warm carpet of the present invention, age distribution, Gender distribution, body fat percentage distribution, weight distribution, etc.)} can be determined in advance by experimentation or simulation so as to be suitable for use in the second warming posture.

  As described above, the floor warm carpet according to the present invention allows the user to make the set temperature Ts of the surface material lower than the temperature Ts1 at the time of the first warming at the time of the second warming. The temperature control of the surface material can be set using the temperature conservative setting means. In other words, it is possible to select whether or not the user performs temperature control using the temperature conservative setting means at his / her own intention, and whether or not to heat at a temperature Ts2 lower than the temperature Ts1.

  In this way, the user uses the floor warming carpet of the present invention after recognizing at which of the temperatures Ts1 and Ts2 the user warms.

  Therefore, when the user selects to perform temperature control of the temperature Ts2 using the temperature conservative setting means, the temperature Ts2 that is not preheated is set to a temperature Ts2 that feels not to be hot. When shifting to the second warming posture, warming can be performed in a state where the discomfort of hotness is sufficiently reduced.

  Furthermore, in this case, since the temperature Ts2 is preset to a temperature at which it feels not hot as described above, the temperature of the surface material is surely adjusted to a comfortable temperature Ts2. Therefore, the problem of the prior art described above: “If the temperature of the surface material is not appropriate for the user after adjusting the temperature of the surface material, in addition to the waiting time for the inevitable temperature change described above, again It is possible to sufficiently prevent the occurrence of “there is a possibility that the user may amplify the uncomfortable feeling of being unusable” due to the complexity of having to adjust the temperature.

  Further, when the user has selected to perform temperature control of the temperature Ts1 without using the temperature moderation setting means, the temperature Ts1 is changed when the posture is changed from the first warming posture to the second warming posture. Even if the control remains as it is, the user himself selects and recognizes the temperature control of the temperature Ts1, so that the user can perform warming in a state where the discomfort of being hotter than before is sufficiently reduced.

  Furthermore, in this case, when the user is in the posture at the time of the first warming, it is selected to perform temperature control of the temperature Ts2 using the temperature conservative setting means, and then the posture is shifted to the posture at the second warming. Or when the user chooses to perform temperature control of the temperature Ts2 using the temperature moderation setting unit again after shifting from the posture at the time of the first warming to the posture at the time of the second warming, Since the temperature of the surface material is surely adjusted to the comfortable temperature Ts2, the problem of the prior art described above: “After adjusting the temperature of the surface material to be lowered, the temperature of the surface material was not appropriate for the user. In this case, in addition to the above-mentioned waiting time for the inevitable temperature change, there is a need to adjust the temperature again, and the user may amplify the unpleasant feeling that it is inconvenient to use. In prevention That.

  As a result, according to the floor warming carpet of the present invention, even when the posture when the user warms is changed, discomfort given to the user in accordance with the change in the posture (change in usage pattern). Therefore, it is possible to perform appropriate temperature control of the surface material so that the heating can be performed in a state in which the temperature is sufficiently reduced.

More specifically, according to the floor warming carpet of the present invention, for example, when the user warms in the above-mentioned first warming posture and when warming in the second warming posture, Even in the case of using the posture, the temperature control of the surface material suitable for each posture can be performed. For example, from the posture in which the user warms mainly with the back of the foot during the first warming (see FIG. 5 described later). The posture in which the lower body other than at least the back of the foot is placed on the surface material during the second warming {see FIG. 4 described later. When the user transitions to the posture on which the user lies on the whole surface (including the so-called “back-up” posture, the “collapse” posture, and the posture of the body lying on the surface material)} Even if there is a part of the body that touches directly on the surface material {or a part of the body that touches the surface material indirectly (if there is another rug between the surface material and the user) It is possible to provide a warm sensation to the user without feeling the body part)} hot.

  Here, in the present invention, as described above, the temperature control means detects the temperature by the temperature detection means so that the actual surface temperature Tsr of the surface material approaches the set temperature Ts set by the user's request. Although the current supply to the heating element is controlled based on the temperature Th of the generated heating element, from the viewpoint of obtaining the above-described effect of the present invention more reliably, the “temperature control means sets the actual surface temperature Tsr of the surface material. It is preferable to “control the temperature Ts”.

  In addition, from the viewpoint of obtaining the above-described effect of the present invention more reliably, in the warm floor carpet of the present invention, the temperature control means receives the temperature control signal from the temperature moderation setting means, and the operation time elapses. A fluctuation temperature control unit for changing the set temperature Ts of the surface material is further provided, and the upper limit value of the temperature control range of the set temperature Ts of the surface material by the fluctuation temperature control unit is the temperature Ts2 at the second warming time. It is preferable that the setting is made as described above (claim 2).

  Thus, when the temperature control means receives an instruction signal for setting the set temperature Ts of the surface material to the temperature Ts2 at the second warming time from the temperature moderation setting means, the temperature control means at the first warming time set by using the temperature setting means. The temperature Ts1 is changed to the temperature Ts2 at the time of the second warming, and the operation of the fluctuation temperature control unit is started. Here, the temperature control range of the set temperature Ts of the surface material that is fluctuated by the fluctuation temperature control by the fluctuation temperature control unit is the temperature Ts2 at the time of the second warming because the upper limit value of the fluctuation is the temperature Ts2 at the second warming. It is possible to more reliably and safely reduce the unpleasant sensation given to the person.

  In addition, when the fluctuation temperature control by the fluctuation temperature control unit is performed as compared with the case where the fluctuation temperature control by the fluctuation temperature control unit is not performed, the upper limit value is the temperature Ts2 at the second warming time, and other than the upper limit value. In the temperature control range, naturally, the temperature is lower than the temperature Ts2 at the time of the second warming, and therefore the energization amount to the heating element can be saved in other temperature control ranges other than the upper limit value. Therefore, by optimizing the fluctuation control pattern, it is also possible to easily obtain a further energy saving effect while giving a sufficient warm feeling to the user.

  Furthermore, when employing the above-described fluctuation temperature control unit, from the viewpoint of more reliably obtaining the effects of the present invention and the additional effect obtained when employing the above-described fluctuation temperature control unit, the surface material by the fluctuation temperature control unit It is preferable that the lower limit value of the temperature control range of the set temperature Ts is set to be equal to or higher than the minimum environmental temperature value Tm when used in the installation space.

  As a result, the fluctuation temperature control is performed at the environmental temperature minimum value Tm or more when used in the installation space, so that the actual surface temperature Tsr of the surface material of the floor warm carpet becomes too low and the user's warm feeling Can be prevented more reliably.

  In addition, the minimum value Tm of the environmental temperature when used in the installation space is the usage environment of the floor warm carpet of the present invention {the change of the average temperature in the installation day, the change of the average temperature in the year (season). , Daily change in average humidity at installation location, annual (seasonal) change in the above average humidity, user information (number of users who share the floor warm carpet of the present invention, age distribution, gender) Distribution, body fat percentage distribution, weight distribution, etc.), etc.} can be determined in advance by experiments or simulations.

Moreover, it is preferable that the floor warm carpet of this invention is used as an auxiliary heating apparatus at the time of heating the installation space, such as an air conditioner, a ceramic fan heater, a stove (electric stove, oil stove, gas stove), etc. It is preferable to be used with the main heating equipment. When used with such a main heating device, the minimum value Tm of the environmental temperature can be easily set. In this case, the minimum value Tm of the environmental temperature can more reliably prevent the user's sense of warmth from being impaired. From the viewpoint, it is preferably set within a temperature range of 20 to 30 ° C, more preferably set within a temperature range of 23 to 27 ° C, and further preferably 25 ° C.

  Further, from the viewpoint of obtaining the effect of the present invention more reliably, the temperature moderation setting means determines whether the posture of the user located on the surface material is one of the first warming posture and the second warming posture. It has a human body detecting means for detecting, and the temperature setting means is a set temperature Ts of the surface material set by the request of the user based on the posture of the user detected by the human body detecting means of the temperature conservative setting means. It is preferable to control energization to the heating element so as to satisfy (Claim 4).

  With this configuration, when the user selects temperature control by the temperature moderation setting unit, the human body detection unit determines whether the user's posture is one of the first warming posture and the second warming posture. You can check if there is.

  Thereby, when the user selects the temperature control by the temperature moderation setting means, if the user's posture is the posture at the time of the second warming by the human body detection means, the temperature control is performed with the set temperature Ts of the surface material as the temperature Ts2. If the posture of the user is the first warming posture by the human body detection means, the temperature control for maintaining the temperature Ts1 without changing the set temperature Ts of the surface material to the temperature Ts2 can be performed. That is, it is possible to perform more precise control so that heating can be performed in a state in which discomfort given to the user is sufficiently reduced in accordance with a change in the posture of the user (change in usage pattern).

  Further, when the above-described fluctuation temperature control means is adopted in addition to the human body detection means, when the user selects temperature control by the temperature moderation setting means, the posture of the user is changed by the human body detection means. 2 If the posture is a warming posture, the surface material set temperature Ts is set to the temperature Ts2, and the fluctuation temperature is controlled. If the posture of the user is the first warming posture by the human body detection means, the surface material set temperature Ts is set. The temperature control can be configured to maintain the temperature Ts1 without using the temperature Ts2.

  When the floor warming carpet of the present invention is provided with the human body detecting means, (1) when the user selects the temperature control by the temperature mode setting means, the control by the above human body detecting means is automatically performed in conjunction with this. (2) When the user selects temperature control by the temperature moderation setting unit, it may be configured to select whether or not to further perform control by the human body detection unit.

  Here, when the floor warming carpet of the present invention is provided with the human body detection means, the human body detection means is mounted on another electrical device that uses information obtained from the human body detection means installed in the installation space for operation control. (Claim 5).

Thus, other electrical equipment {(TV, audio equipment, lighting equipment, heating equipment (air conditioner, ceramic fan heater, electric stove, oil stove, gas stove), refrigerator, washing machine, microwave oven, dishwashing equipment, these By installing the human body detection means on the remote control etc. of the device of the apparatus, the restriction on the arrangement position of the human body detection means is relaxed compared with the case where the human body detection means is mounted on the warm floor carpet itself, and the user's It is possible to more surely check whether the posture is one of the first warming posture and the second warming posture, for example, information on the posture of the user by the human body detection means provided in the heating device. Can be shared between the floor warming carpet and the heating device of the present invention using a known infrared communication technology or the like, more appropriate heating according to the posture of the user can be ensured. Rukoto can. Further, as compared with the case of mounting the human body detecting means is floor heating carpet itself, increase the manufacturing cost of the floor heating carpet itself, it is possible to suppress an increase in price.

  In the warm floor carpet of the present invention, when the human body detection means is mounted on another electrical device, the warm floor carpet itself is further provided with a second human body detection means from the viewpoint of more reliably detecting the human body. May be provided.

  Further, in the floor warming carpet of the present invention, the temperature setting means has a plurality of predetermined temperature setting regions, and the user sets a desired temperature Ts of the desired surface material from the plurality of temperature setting regions. The temperature control means uses the temperature conservative setting means, and the temperature control means changes the set temperature Ts of the surface material to the temperature Ts2 at the second warming time that is lower than the temperature Ts1 at the first warming time. When it is requested to do so, based on the set temperature Ts of the surface material selected by the user from the plurality of temperature setting regions in the temperature setting means, the temperature of the surface material decreases as the set temperature Ts of the surface material decreases. You may employ | adopt the structure which changes the fall width (Ts1-Ts2) of the said temperature so that the fall width (Ts1-Ts2) may become small (Claim 6).

  As described above, the temperature setting means has a plurality of predetermined temperature setting regions, and the user selects a desired set temperature Ts of the surface material from the plurality of temperature setting regions. Thus, the user can easily set the set temperature Ts of the surface material.

  In addition, since the temperature decrease width (Ts1-Ts2) is changed so that the temperature decrease width (Ts1-Ts2) becomes smaller as the set temperature Ts of the surface material becomes lower, When the user selects the high temperature side of the temperature setting region, temperature control at a sufficiently low temperature Ts2 can be realized so as to more surely prevent discomfort that the user feels hot during the second warming. Easy to do. In addition, when the user selects the low temperature side of the plurality of temperature setting regions, the temperature Ts2 is sufficiently high so as to more reliably prevent the user from feeling uncomfortable during the second warming. It is easy to realize temperature control.

  From the viewpoint of obtaining this effect more reliably, the temperature setting means displays a plurality of temperature setting areas to the user and a display selection unit that allows the user to select one of the plurality of temperature setting areas. It is preferable to have (claim 8).

  By providing this display selection section, the user can easily set the set temperature Ts of the surface material without being aware of the specific temperature value.

  Furthermore, in the floor warming carpet of the present invention, when the above-described configuration (Claim 6) is adopted, the temperature setting means includes a plurality of temperature setting regions in order from the highest temperature to the first temperature region and the second temperature. It is preferable that the predetermined range is determined in advance in three regions, that is, the region and the third temperature region.

  Thus, by limiting the plurality of temperature setting regions to the three regions of the first temperature region, the second temperature region, and the third temperature region, the user can set the surface material set temperature Ts. Can be set more easily without being aware of a specific temperature value.

  Also in this case, from the viewpoint of more reliably obtaining this effect, the temperature setting means displays the plurality of temperature setting areas to the user and selects any one of the plurality of temperature setting areas to the user. It is preferable to have a display selection part to be made (claim 8).

  By providing this display selection section, the user can easily set the set temperature Ts of the surface material without being aware of the specific temperature value.

  For example, if the first temperature region, the second temperature region, and the third temperature region are sequentially displayed on the display selection unit as “high”, “medium”, and “low” regions, the user can The set temperature Ts of the surface material can be set more easily from a display range that is easily recognized visually such as “high”, “medium”, and “low” without being aware of a specific temperature value. It becomes like this.

In the floor warm carpet of the present invention,
The main surface of the surface material is configured to be divided into a plurality of heating regions,
A first heating operation mode in which substantially the entire main surface of the surface material is heated, and the plurality of heating regions of the main surface of the surface material are independently heated, and the plurality of heating regions are not simultaneously heated. A heating operation mode switching setting means for setting the second heating operation mode according to a user's request is further provided,
When the user requests the operation in the second heating operation mode using the heating operation mode switching setting unit, the temperature control unit is configured regardless of whether the user requests (using the temperature moderation setting unit). Regardless of whether or not there is a request to perform control at the second warming time set), control at the first warming time set by using the temperature setting means is performed and second warming temperature set by using the temperature moderation setting means is performed. It is good also as a structure which does not perform the control in time (Claim 9).

  With this configuration, even if the floor warm carpet of the present invention is used in combination with other electrical equipment, the occurrence of breaker down can be more reliably prevented.

  For example, when the main surface of the surface material is divided into two heating regions {the half surface (left half surface) of the main surface of the surface material (main surface of the base material) and the other half surface (right half surface) alternately When the heating element is arranged so that it can be heated}, when the user requests the operation in the second heating operation mode using the heating operation mode switching setting means, the left half surface and the right half surface of the main surface of the surface material are By energizing alternately, it is possible to heat with less power consumption than when heating the entire main surface of the normal surface material.

  In addition, for example, in the case of a small number of users such as one user, the entire main surface of the surface material is not heated, and a part (for example, only half surface) of the main surface of the surface material can be used. Therefore, also from this viewpoint, heating can be performed with less power consumption where there are users, and heating without waste can be realized.

  Further, even when the user requests the operation in the second heating operation mode using the heating operation mode switching setting means, the temperature setting means is used regardless of whether or not the user requests. By providing a configuration in which the control during the first warming is performed and the control during the second warming that is set using the temperature conservative setting means is not performed, a sufficient warming sensation can be more reliably given to the user. Will be able to.

Furthermore, in the floor warm carpet of the present invention, when adopting a configuration (claim 9) that realizes the operation in the second heating operation mode described above,
When the user requests the operation in the second heating operation mode by using the heating operation mode switching setting unit, the temperature control means uses the fluctuation temperature control unit 17 regardless of the user's request. The fluctuation temperature control unit is configured to start temperature control of the set temperature Ts of the surface material, regardless of whether or not there is a request for fluctuation temperature control.
The upper limit value of the temperature control range of the set temperature Ts of the surface material by the fluctuation temperature control unit is set to be the temperature Ts1 at the time of the first heating,
Preferably, the lower limit value of the temperature control range of the set temperature Ts of the surface material by the fluctuation temperature control unit is set to be equal to or higher than the minimum value Tm of the environmental temperature when used in the installation space. ).

  Thereby, the energy saving effect can be obtained more easily and reliably while giving a sufficient warm feeling to the user.

  Further, in the warm floor carpet of the present invention, the surface material is formed using a constituent material that does not allow water to pass therethrough and has flexibility, and the base material is unloaded before the load is applied. Preferably, it is formed using a constituent material that can be restored to its original shape (claim 11).

  As a result, at the time of heating by temperature control using the above-described temperature setting means, temperature moderation setting means, and temperature control means (further, the fluctuation temperature control unit), the user can change the posture during the first warming and the second warming temperature. In any of the time postures, softness can be felt when placed on the surface material. For this reason, it is possible to perform heating in a state where the discomfort given to the user is further reduced.

  According to the floor warming carpet of the present invention, even when the posture of the user when warming is changed, the discomfort given to the user according to the change of the posture (change of the use form) is sufficiently obtained. Appropriate temperature control of the surface material can be performed so that heating can be performed in a reduced state.

(First embodiment)
1st Embodiment of the floor warm carpet of this invention is described using FIGS.

More specifically, FIG. 4 shows a scene in which the user 11 warms up using the floor warming carpet 1 in the first warming posture (the posture in which the user 11 puts the back of the foot on the surface material 4). The warm floor carpet 1 is laid on the floor surface 7 and placed on the table 8 and the chair 9. Further, the user 11 sits on the chair 9 and sits on the foot 10. The scene which has mounted the back on the surface material 4 (floor warm carpet 1) is shown.

  Furthermore, FIG. 5 is a schematic diagram showing an example of the case where the user uses the floor warming carpet shown in FIG. 1 in the first warming posture. More specifically, FIG. 5 shows that the user 11 is warmed using the floor warming carpet 1 in the second warming posture (the posture where the user 11 has placed at least the lower body 12 other than the back of the foot on the surface material 4). The floor warm carpet 1 is laid on the floor surface 7, and the user 11 attaches at least the lower body 12 other than the back of the foot 10 to the surface material 4 (floor warm carpet 1). ) Shows the scene shown above.

  Further, FIG. 6 shows the change over time of the set temperature Ts of the surface material and the actual surface temperature Tsr of the surface material when the control using the temperature conservative setting means of the warm floor carpet shown in FIG. 1 is performed. It is a schematic diagram which shows an example of a profile (when the fluctuation temperature control using the fluctuation temperature control part 17 mentioned later is not performed).

  The warm floor carpet 1 of the first embodiment shown in FIGS. 1 and 2 is used by being laid on the floor surface. The main surface on which the user is placed has a substantially rectangular curtain shape and a predetermined area (1). Tatami mat, 2 tatami mats, 3 tatami mats, etc.) and a predetermined thickness. When a load is applied, for example, when the user is placed on the surface facing the user, the portion of the surface where the load is applied is slight. When the load disappears, the sunken part of the surface is restored to its original state.

  As shown in FIGS. 1 and 2, the warm floor carpet 1 is directed to the user side of a curtain-like base material 2 that can be wound and folded, and two main surfaces of the base material 2. A surface material 4 that covers the front surface (main surface facing the user), a back material 5 that covers the back surface (main surface facing the floor surface) facing the floor surface, and the inside of the base material 2 A heating element 3 that generates heat by Joule heat generated by energization, and a temperature detection means 13 that is disposed integrally with the heating element 3 inside the substrate 2 and detects the temperature Th of the heating element 3; And a controller body 6 that is electrically connected to the heating element 3 and the temperature detection means 13 and controls the energization of the heating element 3 based on the temperature Th of the heating element 3 detected by the temperature detection means 13. It has a configuration.

  The base material 2 has a curtain shape whose main surface is substantially rectangular. The base material 2 is a constituent material that can be wound and folded, and is formed using a constituent material that can be restored to its original shape before the load is applied when the load is eliminated. As such a constituent material, for example, urethane foam is preferable.

  The surface material 4 is arrange | positioned so that the surface which faces a user side among the two main surfaces of the base material 2 may be covered. The surface material 4 is a constituent material that does not allow water to pass therethrough and is formed using a constituent material having flexibility. As such a constituent material, for example, polyvinyl chloride is preferably exemplified.

  The back material 5 is disposed so as to cover the back surface facing the floor surface of the two main surfaces of the substrate 2. Similarly to the surface material 4 described above, the back surface material 5 is preferably formed using a material that does not allow water to pass through and has flexibility. As such a constituent material, for example, polyvinyl chloride is preferably exemplified.

  The heating element 3 has a configuration that generates heat due to Joule heat generated by energization. In the case of this embodiment, the heating element 3 is embedded on the side close to the surface material 4 in the base material 2 from the viewpoint of efficiently heating the surface material 4. Has been.

  Moreover, in this embodiment, the heating area | region of the main surface of the surface material 4 can be divided into the whole surface or two using the heating operation mode switch setting means 20 (refer FIG. 2) mentioned later by a user's request | requirement. Further, the heating element 3 is disposed in the base material 2.

  In the present embodiment, the controller body 6 is integrally installed at the corner portion of the warm floor carpet 1 having a curtain shape. A power cord plug (not shown) is connected to the controller body 6, and the power cord plug is inserted into a power outlet (not shown) on the wall of the installation space of the floor warm carpet 1 and used. Is done.

  As shown in FIG. 2, the controller body 6 mainly includes a temperature setting means 14, a temperature moderation setting means 16, and a temperature control means 15, which will be described later.

  The temperature setting means 14 is used for setting the temperature Ts of the surface material 4 during the first warming (see FIG. 4) when the user 11 heats the back of the foot on the surface material 4 (on the floor warming carpet 1). Is set at the request of the user. The temperature setting means 14 has a built-in microcomputer and its peripheral circuit, and transmits information on the set temperature Ts of the surface material 4 set by the operation of the user 11 to the temperature control unit 15 described later. Have.

  The temperature moderation setting means 16 sets the set temperature Ts of the surface material at the time of the second warming (see FIG. 5) in which the user 11 warms the posture with the lower body 12 other than the back of the foot placed on the surface material 4. This is for setting at the user's request (by the user's operation) such that the temperature Ts2 is lower than the temperature Ts1 at the time of the first warming.

  For example, when the user warms in the second warming posture (FIG. 5), the temperature mode setting means 16 is operated to send a control signal to the temperature control means 15 described later, whereby the first warming posture (FIG. 5). The set temperature Ts of the surface material 4 can be lowered as compared with the case of heating in 4).

  The temperature control means 15 is connected to the heating element 3, the temperature detection means 13, the temperature setting means 14, and the temperature moderation setting means 16, and based on the temperature Th of the heating element 3 detected by the temperature detection means 13. This is for controlling energization to the heating element 3.

  The temperature control means 15 is configured to receive a temperature control signal transmitted from either the temperature setting means 14 or the temperature moderation setting means 16 by the operation of the user 11. In the temperature control means 15, the actual surface temperature Tsr of the surface material is set using either the temperature setting means 14 or the temperature moderation setting means 16 at the request of the user (by the user's operation). The energization to the heating element 3 is controlled based on the temperature Th of the heating element 3 detected by the temperature detection means 13 so as to approach the set temperature Ts of the surface material 4.

  Here, the floor warm carpet of the present embodiment is configured so that the actual temperature Tsr of the surface material 4 can be indirectly monitored by detecting the temperature Th of the heating element 3 by the temperature detecting means 13 during use. Yes.

  The temperature control means 15 incorporates a microcomputer and its peripheral circuits, and in these, a calculation formula that can calculate (convert) the actual temperature Tsr of the surface material 4 from the temperature Th of the heating element 3. Alternatively, a table in which converted data is organized is stored. These calculation formulas or tables show the usage environment of the floor warm carpet 1 {daily change in average temperature at the installation site, annual (seasonal) change in the above average temperature, daily change in average humidity at the installation site, Annual (seasonal) change in the above average humidity, user information (number of users who share the floor warm carpet of the present invention, age distribution, gender distribution, body fat percentage distribution, weight distribution, etc.), etc. } Is determined in advance by experiments or simulations.

  For example, in the warm floor carpet of the present embodiment, the temperature control means 15 is based on the temperature Th of the heating element detected by the temperature detection means 13 (and thus the actual temperature Tsr of the surface material 4). When the temperature Tsr exceeds the set temperature Ts of the surface material 4 set by the user 11, the power supply to the heating element 3 is turned off.

  More specifically, the temperature control means 15 is configured so that the temperature Th of the heating element detected by the temperature detection means 13 (and thus the actual temperature Tsr of the surface material 4) is set by the user 11 to the set temperature Ts of the surface material 4. When it becomes below, it controls so that the electricity supply to the heat generating body 3 is turned ON. In this way, the temperature control means 15 has a configuration that performs so-called ON-OFF control of energization to the heating element 3.

  Here, in the present embodiment, the temperature Ts1 during the first warming is higher than that during the second warming and is a temperature range between the “lower limit A” and the “upper limit A” described above. Is a “set temperature value A” that is determined in advance. In the present embodiment, the temperature Ts2 during the second warming is lower than that during the first warming and is in the temperature range between the “lower limit B” and the “upper limit B” described above. This is a predetermined “set temperature value B” selected from the inside.

  The warm floor carpet 1 of the present embodiment includes the above-described temperature detection means 13, temperature setting means 14, temperature control means 15, and temperature moderation setting means 16, so that the following can be performed.

  That is, the floor warm carpet 1 of the present embodiment allows the user to use the temperature moderation setting means 16 so that the set temperature Ts of the surface material 4 is lower than the temperature Ts1 at the first warming time during the second warming time. The temperature control of the surface material 4 can be set to be Ts2.

  In other words, the user can select whether or not to perform temperature control using the temperature moderation setting means 16 by his / her own intention, or whether or not to heat at a temperature Ts2 lower than the temperature Ts1. Thus, the user can use the floor warming carpet 1 after recognizing at which of the temperatures Ts1 and Ts2 the user warms.

  Therefore, when the user selects to perform the temperature control of the temperature Ts2 using the temperature moderation setting unit 16, the temperature Ts2 is set to the temperature Ts2 that the user feels that the temperature is not set in advance. When moving to the second warming posture, the warming can be performed in a state where the discomfort of hotness is sufficiently reduced.

  Furthermore, in this case, since the temperature Ts2 is set in advance to a temperature at which it feels not hot as described above, the temperature of the surface material 4 is surely adjusted to a comfortable temperature Ts2. Therefore, the problem of the prior art described above: “If the temperature of the surface material is not appropriate for the user after adjusting the temperature of the surface material, in addition to the waiting time for the inevitable temperature change described above, again It is possible to sufficiently prevent the occurrence of “there is a possibility that the user may amplify the uncomfortable feeling of being unusable” due to the complexity of having to adjust the temperature.

  Further, when the user has selected to perform the temperature control of the temperature Ts1 without using the temperature moderation setting means 16, the temperature Ts1 is changed when the posture is changed from the first warming posture to the second warming posture. Even if the temperature control is maintained, the user selects and recognizes the temperature control of the temperature Ts1 by himself, so that the user can perform the heating in a state in which the discomfort that is hotter than before is sufficiently reduced.

  Further, in this case, when the user is in the posture at the time of the first warming, it is selected to perform temperature control of the temperature Ts2 using the temperature moderation setting unit 16 again, and then the posture at the time of the second warming is changed. When the transition is made, or when the user selects to perform the temperature control of the temperature Ts2 using the temperature moderation setting unit 16 after the transition from the posture at the time of the first warming to the posture at the time of the second warming. However, since the temperature of the surface material 4 is surely adjusted to a comfortable temperature Ts2, the problem of the prior art described above: “After adjusting the temperature of the surface material to be lowered, the temperature of the surface material is appropriate for the user. If this is not the case, in addition to the above-mentioned waiting time for the inevitable temperature change, there is a need to adjust the temperature again, and the user may amplify the uncomfortable feeling of being unusable. '' The ten It can be prevented.

  As a result, in the warm floor carpet 1, even when the user changes the posture when warming, the discomfort given to the user according to the change in the posture (change in use form) is sufficiently reduced. Thus, it is possible to perform appropriate temperature control of the surface material so that the heating can be performed in the above state.

  More specifically, according to the floor warming carpet 1, for example, any posture of when the user warms in the above-described first warming posture and when warming in the second warming posture. Even in the case of use in the above, since the temperature control of the surface material suitable for each posture can be performed, for example, from the posture in which the user warms mainly with the back of the foot during the first warming (see FIG. 5), the second warming is performed. At least a posture in which the lower body other than the back of the foot is placed on the surface material 4 (see FIG. 4). When the user transitions to the posture on which the user lies on the surface material 4 (including the so-called “back-up” posture, the “collapse” posture, the posture of the body lying on the surface material, etc.)} However, the body part that directly touches the surface material {or the body part that indirectly touches the surface material 4 (the rug when another rug is placed between the surface material 4 and the user) It is possible to provide the user with a preferable warm sensation without feeling hot in the body part touching the top)}.

  Here, in this embodiment, as described above, the temperature control means 15 detects the temperature so that the actual surface temperature Tsr of the surface material 4 approaches the set temperature Ts set by the user's request. Although energization to the heating element is controlled based on the temperature Th of the heating element detected by the means, from the viewpoint of obtaining the above-described effect of the present invention more reliably, “the temperature control means 15 is the actual temperature of the surface material 4. It is preferable to control so that the surface temperature Tsr becomes the set temperature Ts ”.

  Furthermore, in the case of the warm floor carpet 1 of the present embodiment, when the temperature control unit 15 receives the temperature control signal from the temperature moderation setting unit 16, the set temperature Ts of the surface material 4 is changed as the operation time elapses. A fluctuation temperature control unit 17 is provided.

  The upper limit value of the temperature control range of the set temperature Ts of the surface material 4 by the fluctuation temperature control unit 17 is set to be the temperature Ts2 at the second warming time.

Thus, when the temperature control means 15 receives the instruction signal for setting the set temperature Ts of the surface material 4 to the temperature Ts2 at the time of the second warming from the temperature moderation setting means 17, the first temperature set by using the temperature setting means 15 is set. The temperature Ts1 at the time of the first warming is changed to the temperature Ts2 at the time of the second warming, and the operation of the fluctuation temperature control unit 17 is started. Here, the temperature control range of the set temperature Ts of the surface material that is fluctuated by the fluctuation temperature control by the fluctuation temperature control unit 17 is the temperature Ts2 at the time of the second warming because the upper limit value of the fluctuation is the second warming time. It is possible to more reliably and safely reduce the unpleasant sensation given to the user.

  In addition, when the fluctuation temperature control is performed by the fluctuation temperature control unit 17, the upper limit value is the temperature Ts2 at the second warming time and not the upper limit value when the fluctuation temperature control unit 17 performs the fluctuation temperature control as compared with the case where the fluctuation temperature control unit 17 does not perform the fluctuation control. Naturally, in the other temperature control range, the temperature is lower than the temperature Ts2 at the time of the second warming, and therefore, the energization amount to the heating element 3 can be saved in the other temperature control range other than the upper limit value. Therefore, by optimizing the fluctuation control pattern, it is also possible to easily obtain a further energy saving effect while giving a sufficient warm feeling to the user.

  Further, the lower limit value of the temperature control range of the set temperature Ts of the surface material 4 by the fluctuation temperature control unit 17 is set to be equal to or higher than the minimum value Tm of the environmental temperature when used in the installation space of the warm floor carpet 1. ing.

  As a result, the fluctuation temperature control is performed at the environmental temperature minimum value Tm or more when used in the installation space of the warm floor carpet 1, so that the actual surface temperature Tsr of the surface material 4 of the warm floor carpet 1 is lowered. Thus, it is possible to more reliably prevent the user's sense of warmth from being impaired.

  The minimum value Tm of the environmental temperature when used in the installation space of the warm floor carpet 1 is determined in advance by experiments, simulations, etc. in consideration of the use environment of the warm floor carpet 1 as described above. I can keep it.

  The warm floor carpet 1 is preferably used as an auxiliary heating device for heating the installation space, and is mainly used for an air conditioner, a ceramic fan heater, a stove (electric stove, oil stove, gas stove), and the like. It is preferably used with a heating device. When used with such a main heating device, the minimum value Tm of the environmental temperature can be easily set. In this case, the minimum value Tm of the environmental temperature can more reliably prevent the user's sense of warmth from being impaired. From the viewpoint, it is preferably set within a temperature range of 20 to 30 ° C, more preferably set within a temperature range of 23 to 27 ° C, and further preferably 25 ° C.

  Next, in the floor warm carpet 1 of the present embodiment, an example of the operation when performing the control using the temperature moderation setting means 16 and the fluctuation temperature control unit 17 is set for the surface material 4 shown in FIGS. 3 and 6. A description will be given using a profile of the change with time of the temperature Ts and the change with time of the actual surface temperature Tsr of the surface material 4.

  First, a user lays the floor warm carpet 1 of the present embodiment on the floor surface of an installation space such as a room in a house and plugs the power cord into a power outlet provided on the wall of the installation space.

  Next, as shown in FIG. 4, when the user warms in the first warming posture, the user usually operates the temperature setting means 14 of the controller body 6 (for example, provided in the temperature setting means 14). Further, by setting the temperature Ts1 of the surface material 4 (by pressing a push button for selecting the set temperature Ts1 or the like), it is possible to obtain a warmth that does not feel cold even when the temperature of the body is relatively narrow such as the back of the foot. A preferable temperature (for example, 37 ° C.) is set.

Then, the temperature control means 15 that has received the control signal related to the set temperature Ts1 of the surface material 4 from the temperature setting means 14 determines the set temperature Ts1 (for example, 37 ° C.) of the surface material 4 and the heating element 3 obtained from the temperature detection means 13. Based on the temperature Th, energization of the heating element 3 by ON-OFF control is started. The actual temperature setting temperature Ts of the surface material 4 is controlled by the temperature control means 15.
r becomes substantially constant at a temperature value close to the set temperature Ts1 of the surface material 4.

  Next, as shown in FIG. 5, when the user changes the posture from the first warming posture to the second warming posture, the user uses the temperature moderation setting means 16 of the controller body 6 (for example, By pressing a push button for selecting the set temperature Ts2 provided in the temperature moderation setting means 16, the set temperature Ts2 of the surface material 4 (at least in the heating of a relatively wide range of the body other than the lower back of the foot) A preferable temperature (for example, 35 ° C.) at which warmth that does not feel hot is obtained is set.

  The temperature control means 15 that has received the control signal related to the set temperature Ts2 of the surface material 4 from the temperature moderation setting means 16 gives priority to this control signal from the temperature setting means 14 over the control signal related to the set temperature Ts1 of the surface material 4. Based on the set temperature Ts2 (for example, 35 ° C.) of the surface material 4 and the temperature Th of the heating element 3 obtained from the temperature detecting means 13, the heating element 3 is started to be energized by the ON / OFF control. By the control by the temperature control means 15, the actual temperature setting temperature Tsr of the surface material 4 becomes substantially constant at a temperature value close to the setting temperature Ts2 of the surface material 4 (profiles of Ts and Tsr at the operation time t0 in FIG. 3). And the profile of Ts and Tsr in FIG. 6).

  In particular, in this case, the actual temperature Tsr of the surface material 4 can be easily set to a temperature suitable for warming only by performing an operation such as pressing the temperature mode setting means 16 of the controller body 6 and pushing a button. Therefore, the complexity of the adjustment operation of the set temperature Ts of the surface material 4 can be sufficiently reduced as compared with the conventional case, and the usability is improved.

  Further, during operation using the temperature moderation setting means 16, (1) when the user selects the fluctuation temperature control by the fluctuation temperature control unit 17 provided in the temperature control means 15, or (2) temperature When the user selects the operation using the conservative setting means 16, when the fluctuation temperature control by the fluctuation temperature control unit 17 is automatically started, the following fluctuation temperature control is started.

  That is, when the fluctuation temperature control by the fluctuation temperature control unit 17 of the temperature control means 15 is started, the set temperature Ts of the surface material 4 (the set temperature Ts2 of the surface material 4) is Ts in the operation times t1 to t8 in FIG. As shown in the profile, the time fluctuates as the driving time elapses.

  Here, in the case of the present embodiment, as described above, the upper limit value of the temperature control range of the set temperature Ts of the surface material 4 (set temperature Ts2 of the surface material 4) by the fluctuation temperature control unit 17 is the second value. The temperature is set to be the temperature Ts2 at the time of warming (the temperature Ts2 at the time of the second warming when the fluctuation temperature control unit 17 is not used, for example, 35 ° C.). In addition, the lower limit value of the temperature control range of the set temperature Ts of the surface material 4 by the fluctuation temperature control unit 17 is set to be equal to or higher than the minimum value Tm of the environmental temperature when used in the installation space.

  And the temperature control means 15 is based on ON-OFF control to the heat generating body 3 based on the set temperature Ts2 of the surface material 4 that fluctuates within the above temperature range and the temperature Th of the heat generating body 3 obtained from the temperature detecting means 13. Energize.

  By the control by the temperature control means 15, the actual temperature setting temperature Tsr of the surface material 4 is equal to the set temperature Ts2 of the surface material 4 with a predetermined time (for example, operation times t1 to t8 shown in FIG. 3) as one cycle. It fluctuates at a temperature value close to the set temperature Ts2 of the surface material 4 along with the fluctuation (see the profile of Tsr in the operation time t1 to t8 in FIG. 3).

  For example, in this case, the set temperature Ts2 of the surface material 4 is lower than the temperature Ts2 during the second warming (temperature Ts2 during the second warming when the fluctuation temperature control unit 17 is not used, for example, 35 ° C.) at an appropriate interval. (E.g., 1 ° C, 5 ° C, 1 ° C, 2 ° C, lower), so that the lower body 12 in a wider area than the back of the foot touches the floor warm carpet 1 directly as shown in FIG. Thus, it is possible to perform safe temperature control that sufficiently prevents the above-mentioned problem, and to expect an energy saving effect as compared with the case where the ON-OFF temperature control at the first warming time described above is simply performed.

(Second Embodiment)
Next, 2nd Embodiment of the floor warm carpet of this invention is described using FIG.

  FIG. 7 is a control block diagram showing the basic configuration of the second embodiment of the warm floor carpet of the present invention. For convenience of explanation, the same or corresponding parts as those of the warm floor carpet 1 according to the first embodiment will be described with the same reference numerals.

  The warm floor carpet 1A of the second embodiment has a low temperature setting means 16 having a different configuration from the low temperature setting means 16 mounted on the warm floor carpet 1 of the first embodiment. The configuration other than performing control for using the floor has the same configuration as the warm floor carpet 1 of the first embodiment.

  Therefore, in the following description, the temperature moderation setting means 16 which is a component different from the warm floor carpet 1 of the first embodiment will be described.

  As shown in FIG. 7, the temperature moderation setting means 16 mounted on the floor warming carpet 1 of the second embodiment is such that the posture of the user located on the surface material 4 is the first warming posture and the second warming time. Human body detecting means 22 for detecting any one of these postures. The temperature setting means 15 generates heat based on the posture of the user detected by the human body detection means 22 of the temperature moderation setting means 16 so that the set temperature Ts of the surface material 4 set by the user's request is reached. It is configured to control energization to the body.

  With this configuration, when the user selects the temperature control by the temperature moderation setting unit 16, the human body detection unit 22 causes the posture of the user to be either the first warming posture or the second warming posture. It can be confirmed whether it is.

  Thereby, when the user selects temperature control by the temperature moderation setting means 16, if the user's posture is the posture at the time of the second warming by the human body detection means 22, the set temperature Ts of the surface material 4 is set to the temperature Ts2. If temperature control is performed and the posture of the user is the posture at the time of the first warming by the human body detection means, the temperature control for maintaining the temperature Ts1 without changing the set temperature Ts of the surface material 4 to the temperature Ts2 may be performed. it can. That is, more precise control can be performed so that heating can be performed in a state in which discomfort given to the user is sufficiently reduced in accordance with a change in the posture of the user (change in usage pattern).

  Further, when the above-described fluctuation temperature control means 17 is employed in addition to the human body detection means 22, when the user selects the temperature control by the temperature moderation setting means 16, the human body detection means 22 causes the user to If the posture is the second warming posture, the set temperature Ts of the surface material 4 is set to the temperature Ts2, and the fluctuation temperature control is performed. If the posture of the user is the first warming posture by the human body detection means 22, the surface The temperature control for maintaining the temperature Ts1 without changing the set temperature Ts of the material 4 to the temperature Ts2 can be performed.

When the human body detection means 22 is provided, (1) when the user selects the temperature control by the temperature moderation setting means 16, the above-described human body detection means 22 automatically controls in conjunction with this. Alternatively, (2) when the user selects the temperature control by the temperature moderation setting unit 16, it may be configured to select whether or not the control by the human body detection unit 22 is further performed.

  Here, when the human body detection unit 22 is provided, the human body detection unit 22 uses other information obtained from the human body detection unit 22 installed in the installation space of the warm floor carpet 1A of the second embodiment for operation control. It is good also as a structure mounted in the electric equipment.

  In this way, other electric devices installed in the same installation space as the floor warming carpet 1A of the second embodiment {(TV, audio device, lighting device, heating device (air conditioner, ceramic fan heater, electric stove, oil stove, Gas stove), refrigerator, washing machine, microwave oven, dish washing device, operation remote controller for these devices, etc.} by installing the human body detection means 22 to install the human body detection means 22 on the warm floor carpet 1A itself Compared to the above, the restriction on the arrangement position of the human body detection means 22 is relaxed, and it is confirmed more reliably whether the posture of the user is one of the first warming posture and the second warming posture. Will be able to.

  For example, the floor warming carpet 1A and the heating device share information on the posture of the user by the human body detection means 22 provided on the main body of the heating device such as an air conditioner or a remote controller using a known infrared communication technology. If possible, appropriate heating according to the posture of the user can be further ensured.

  Moreover, compared with the case where the human body detection means 22 is mounted on the warm floor carpet 1A itself, an increase in manufacturing cost and an increase in sales price of the warm floor carpet 1A itself can be suppressed.

  In addition, in the warm floor carpet of the present invention, when the human body detection means is mounted on another electrical device, and when emphasizing more reliable human body detection, the warm floor carpet 1A itself also has a second human body. You may provide a detection means as needed.

(Third embodiment)
Next, a third embodiment of the warm floor carpet of the present invention will be described.

  The warm floor carpet (not shown) of the third embodiment includes a temperature setting means (not shown) having a different configuration from the temperature setting means 14 mounted on the warm floor carpet 1 of the first embodiment described above. Other than performing temperature control means (not shown) having a configuration different from the temperature control means 15 mounted on the warm floor carpet 1 of the embodiment and performing control for using the temperature setting means and the temperature control means. Has the same configuration as the warm floor carpet 1 of the first embodiment.

  Therefore, in the following description, a temperature moderation setting unit and a temperature control unit, which are components different from the warm floor carpet 1 of the first embodiment, will be described. For convenience of explanation, the same or equivalent parts as those of the warm floor carpet 1 of the embodiment will be described with the same reference numerals.

  In the warm floor carpet 1 of the third embodiment, the temperature setting means 16 has a plurality of predetermined temperature setting areas, and the user sets a desired surface material 4 from the plurality of temperature setting areas. The temperature Ts is selected.

Further, the temperature control means 15 requires the user to set the set temperature Ts of the surface material 4 to the temperature Ts2 at the second warming time lower than the temperature Ts1 at the first warming time by using the temperature moderation setting means 16. In this case, the following temperature control is performed. That is, in this case, the temperature control unit 15 determines that the set temperature Ts of the surface material 4 is based on the set temperature Ts of the surface material 4 selected by the user from the plurality of temperature setting regions in the temperature setting unit 16. The temperature reduction width (Ts1-Ts2) is changed so that the temperature reduction width (Ts1-Ts2) decreases as the temperature decreases.

  As described above, the temperature setting means 16 has a plurality of predetermined temperature setting regions, and the user selects a desired set temperature Ts of the surface material 4 from the plurality of temperature setting regions. Therefore, the user can easily set the set temperature Ts of the surface material 4.

  In addition, since the temperature decrease width (Ts1-Ts2) is changed so that the temperature decrease width (Ts1-Ts2) becomes smaller as the set temperature Ts of the surface material 4 becomes lower, When the user selects the high temperature side of the temperature setting range, temperature control at a sufficiently low temperature Ts2 is realized so as to more surely prevent discomfort that the user feels hot during the second heating. Can be easily done. In addition, when the user selects the low temperature side of the plurality of temperature setting regions, the temperature Ts2 is sufficiently high so as to more reliably prevent the user from feeling uncomfortable during the second warming. It is easy to realize temperature control.

  From the viewpoint of obtaining this effect more reliably, the temperature setting means 14 displays a plurality of temperature setting areas to the user, and also allows the user to select any one of the plurality of temperature setting areas ( (Not shown).

  By providing this display selection section, the user can set the set temperature Ts of the surface material 4 more easily without being aware of a specific temperature value.

  Further, when the configuration of the present embodiment is adopted, the temperature setting unit 15 includes a plurality of temperature setting regions in the order of the highest temperature, the first temperature region, the second temperature region, and the third temperature region. It is preferable that the number is predetermined in three regions.

  Thus, by limiting the plurality of temperature setting regions to the three regions of the first temperature region, the second temperature region, and the third temperature region, the user can set the temperature of the surface material 4. Ts can be set more easily without being aware of a specific temperature value.

  Also in this case, from the viewpoint of obtaining this effect more reliably, the temperature setting means 14 displays the plurality of temperature setting areas to the user and any one of the plurality of temperature setting areas to the user. It is preferable to have a display selection unit (not shown) for selection.

  By providing this display selection section, the user can set the set temperature Ts of the surface material 4 more easily without being aware of a specific temperature value.

  For example, if the first temperature region, the second temperature region, and the third temperature region are sequentially displayed on the display selection unit as “high”, “medium”, and “low” regions, the user can The set temperature Ts of the surface material can be set more easily from a display range that is easily recognized visually such as “high”, “medium”, and “low” without being aware of a specific temperature value. It becomes like this.

  For example, when the user looks at the display selection unit of the temperature setting unit 14 and selects the “high” setting, the temperature control unit is initially set in advance so as to control the set temperature Ts of the surface material 4 to be, for example, 50 ° C. When the user looks at the display selection unit of the temperature setting unit 14 and selects the “medium” setting, the temperature control unit controls in advance so that the set temperature Ts of the surface material 4 is, for example, 37 ° C. When initial setting is performed and the user views the display selection unit of the temperature setting unit 14 and selects “low” setting, the temperature control unit controls the set temperature Ts of the surface material 4 to be, for example, 25 ° C. Initial settings may be made in advance.

  Note that the first temperature region, the second temperature region, and the third temperature region to be displayed on the display selection unit are displayed as the above-described character representations of “high”, “medium”, and “low”. There is no limitation, and other character expressions may be used. For example, it may be displayed as areas “1”, “2”, and “3” in order, or may be displayed as areas “A”, “B”, and “C”, respectively, “strong”, “medium” ”And“ weak ”areas may be displayed.

  The plurality of temperature setting regions may be two or more regions, and is not limited to the above three regions.

  Further, in the warm floor carpet of the third embodiment, a configuration in which the human body detection means 22 is mounted on the temperature moderation setting means 16 described in the warm floor carpet 1A of the second embodiment described above may be adopted.

(Fourth embodiment)
Next, 4th Embodiment of the floor warm carpet of this invention is described using FIG.8, FIG.9 and FIG.10.

  FIG. 8 is a control block diagram showing the basic configuration of the fourth embodiment of the warm floor carpet of the present invention. FIG. 9 is a schematic diagram illustrating an example of the case where the floor warm carpet 1B according to the fourth embodiment is operated in the first heating operation mode. Furthermore, FIG. 10 is a schematic diagram showing an example of the case where the floor warm carpet 1B of the fourth embodiment is operated in the second heating operation mode. For convenience of explanation, the same or corresponding parts as those of the warm floor carpet 1 according to the first embodiment will be described with the same reference numerals.

  As shown in FIG. 8, the warm floor carpet 1B of the fourth embodiment has the same configuration as the warm floor carpet 1 of the first embodiment except for the following. That is, unlike the warm floor carpet 1 of the first embodiment, the warm floor carpet 1B of the fourth embodiment has a heating operation mode switching setting means 20 that is electrically connected to the temperature control means 15. Furthermore, unlike the warm floor carpet 1 of the first embodiment, the warm floor carpet 1B of the fourth embodiment corresponds to the first heating operation mode and the second heating operation mode set by the heating operation switching setting means 20. Thus, the main surface of the surface material 4 is divided into two heating regions.

  Therefore, in the following description, the heating operation mode switching setting unit 20 which is a component different from the warm floor carpet 1 of the first embodiment and the temperature control unit 15 that performs temperature control using the heating operation mode switching setting unit 20 will be described.

  As shown in FIG.9 and FIG.10, the floor warm carpet 1B of 4th Embodiment divided | segmented into the heating of the substantially whole main surface S of the surface material 4, and two heating area | regions (area | region S1 and area | region S2). The heating element 3 is disposed in the base material 2 so that both heating and heating can be performed.

  Further, as shown in FIG. 8, the warm floor carpet 1B of the fourth embodiment is further provided with a heating operation mode switching setting means 20.

  The heating operation mode switching setting means 20 includes a first heating operation mode in which substantially the entire main surface S of the surface material 4 is heated, and the two heating regions (region S1 and region) of the main surface S of the surface material 4. This is for setting a second heating operation mode in which S2) is independently heated and the two heating areas (area S1 and area S2) are not simultaneously heated at the request of the user.

In addition, when the user requests the operation in the second heating operation mode using the heating operation mode switching setting unit 20, the temperature control unit 15 (temperature modest setting unit). 16) (regardless of whether or not there is a request for performing control at the second warming time set using 16), the control at the first warming time set using the temperature setting means 14 is performed, and the temperature conservative setting means 16 is used. It is set as the structure which does not perform the control at the time of the 2nd heating set.

  Regardless of whether or not there is a request to perform control at the second warming time set using the temperature moderation setting means 16, the control at the first warming time set using the temperature setting means 14 is preferentially performed. By doing so, even if the floor warm carpet 1B is used in combination with other electrical equipment, the occurrence of breaker down can be more reliably prevented.

  For example, when the heating element 3 is disposed so that the left half surface (region S1) and the other right half surface (region S2) of the main surface S (main surface of the base material) of the surface material 4 can be alternately heated, When the operation in the second heating operation mode is requested using the heating operation mode switching setting means 20, the left half surface (region S1) and the right half surface (region S2) of the main surface S of the surface material 4 are alternately energized. Thereby, compared with the case where the whole main surface S of the normal surface material 4 is heated, it can heat with less power consumption.

  Further, for example, when the number of users is small, such as when the number of users is small, the entire surface of the main surface S of the surface material 4 is not heated, and a part of the main surface S of the surface material 4 such as the left half surface (region S1) ) Can also be used, and from this point of view, heating can be performed with less power consumption where there are users, and heating without waste can be realized.

  Furthermore, even if the user uses the heating operation mode switching setting means 20 to request operation in the second heating operation mode, the temperature setting means 14 is used regardless of whether or not the user requests. The control at the time of the first warming that is set is given priority, and the control at the time of the second warming that is set by using the temperature moderation setting means 22 is not performed. Can be given more reliably.

  Further, in the case of the warm floor carpet 1B of the fourth embodiment, the temperature control means 15 uses the heating operation mode switching setting means 20 to request the user to operate in the second heating operation mode. The temperature control of the set temperature Ts of the surface material by the fluctuation temperature control unit 17 is started regardless of whether or not there is a request (regardless of whether there is a request to perform fluctuation temperature control using the fluctuation temperature control unit 17). May be.

  In this case, the upper limit value of the temperature control range of the set temperature Ts of the surface material 4 by the fluctuation temperature control unit 17 is set to be the temperature Ts1 at the time of the first heating, and the surface by the fluctuation temperature control unit 17 It is preferable that the lower limit value of the temperature control range of the set temperature Ts of the material 4 is set to be equal to or higher than the minimum value Tm of the environmental temperature when used in the installation space.

  Thereby, the energy saving effect can be obtained more easily and reliably while giving a sufficient warm feeling to the user.

  Further, when the heating element 3 is energized also in the warm floor carpet 1B of the fourth embodiment, the human body detection means is added to the temperature moderation setting means 16 described in the warm floor carpet 1A of the second embodiment described above. A configuration in which 22 is mounted may be employed.

  Also, in the warm floor carpet 1B of the fourth embodiment, when the heating element 3 is energized, the temperature setting means 16 and the temperature control means 15 described in the warm floor carpet of the third embodiment described above are used. You may employ | adopt the structure to mount.

Further, when the heating element 3 is energized also in the warm floor carpet 1B of the fourth embodiment, the human body detection means is added to the temperature moderation setting means 16 described in the warm floor carpet 1A of the second embodiment described above. You may employ | adopt simultaneously the structure which mounts the structure which mounts the temperature setting means 16 and the temperature control means 15 which were described in the floor warm carpet of 3rd Embodiment described previously.

(Other variations)
The warm floor carpets of the first to fourth embodiments of the present invention have been described above. However, the warm floor carpet of the present invention is limited to the above-described warm floor carpets of the first to fourth embodiments. is not.

  For example, as the floor warming carpet 1 of the first embodiment, the aspect in which the controller body 6 is integrally installed at the corner has been described. However, in the floor warming carpet of the present invention, the controller body 6 is disposed at this position. It is not limited. In the present invention, the controller body 6 may be physically provided separately from the warm floor carpet 1, for example, a remote controller physically provided separately from the warm floor carpet 1. In this case, the floor warm carpet 1 and the remote controller (controller body 6) mutually transmit and receive control signals necessary for temperature control by infrared communication using a known remote control technology using infrared communication, and the heating element 3 What is necessary is just to comprise so that temperature control can be performed.

  In this case, whether the temperature mode setting unit 16 includes the human body detection unit 22 or the temperature mode setting unit 16 does not include the human body detection unit 22, the controller The body 6 may be physically provided separately from the warm floor carpet 1 as a remote controller. Further, in this case, the remote controller may be mounted on another electrical device installed in the same installation space as the warm floor carpet 1. Thus, compared with the case where the controller body 6 is mounted on the warm floor carpet itself, an increase in manufacturing cost and an increase in sales price of the warm floor carpet 1 itself can be suppressed.

  For example, as the heated floor carpet 1 according to the first embodiment, the aspect in which the main surface on which the user is mounted has a substantially rectangular curtain shape has been described. However, the shape of the main surface on which the user of the heated floor carpet according to the present invention is mounted. Is not limited to this. The shape of the main surface on which the user of the warm floor carpet of the present invention is placed can be appropriately changed according to the shape of the floor surface of the installation space or the user's preference. For example, the shape of the main surface on which the user of the warm floor carpet of the present invention is placed may be a substantially circular shape, a substantially elliptical shape, a substantially triangular shape, or a substantially hexagonal shape.

  In addition, as described with reference to FIGS. 9 and 10, as the floor warming carpet 1 </ b> B of the fourth embodiment, the surface material is used by using the heating operation mode switching setting unit 20 (see FIG. 8) at the request of the user. Heating can be performed both when heating the entire heating area of the four main surfaces S and when heating the main surface S of the surface material 4 divided into two heating areas (region S1 and region S2). The embodiment in which the heating element 3 is disposed in the base material 2 has been described. However, the aspect at the time of dividing | segmenting the heating area | region of the main surface of the surface material 4 of the floor warm carpet of this invention is not limited to this. The aspect at the time of dividing | segmenting the heating area | region of the main surface of the surface material 4 of the floor warming carpet of this invention is an area | region or user with high use frequency (area | region where a user heats frequently) among the floor surfaces of installation space. It can be appropriately changed in consideration of the preference, and may be divided into two or more.

  An example different from the example shown in FIG. 10 will be described with reference to FIG. FIG. 11 is a schematic diagram showing another example when the warm floor carpet 1B shown in FIG. 10 is operated in the second heating operation mode.

For example, as shown in FIG. 11, the main surface S of the surface material 4 of the warm floor carpet 1B is divided into three regions (region S1, region S2, region S3), and the heating operation mode switching setting means 20 (see FIG. 2). ), Only the area S1 is heated (heating ON), and the areas S2 and S3 are not heated (
State of heating OFF), heating only area S2 (heating ON) and not heating area S1 and area S3 (heating OFF), heating only area S3 (heating ON), and heating area S1 and area S2 (no heating) You may comprise so that it can heat so that a heating OFF state may be repeated in order. The areas of the region S1, the region S2, and the region S3 at this time may be the same or different.

  Further, one of the region S1, the region S2, and the region S3 may not be always heated (heating OFF), and the remaining two regions may be alternately heated in the heating ON and heating OFF states. Furthermore, one of the region S1, the region S2, and the region S3 may not be always heated (heating OFF), and the remaining two regions may be heated simultaneously with the heating ON and heating OFF states. Further, two of the regions S1, S2, and S3 may not be always heated (heating OFF), and only the remaining one region may be heated in the heating ON and heating OFF states.

  By configuring in this way, it is possible to specify a region having a high usage frequency (a region where the user is frequently warmed) from the floor surface of the installation space, or to take into account the user's preference and to reduce comfort. Heating is possible.

  According to the warm floor carpet of the present invention, even if the warming carpet is laid on the indoor floor surface, even if the posture of the user is changed, the posture changes (changes in usage pattern). Accordingly, it is possible to perform appropriate temperature control of the surface material so that the user can perform warming in a state in which discomfort given to the user is sufficiently reduced.

  Therefore, the floor warm carpet of the present invention can be suitably applied to heating applications for floor surfaces of a wide range of buildings such as hospitals, public facilities, and commercial facilities as well as residential homes.
