Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature control device for electric heating appliances such as electric carpets, electric stoves, and electric blankets.

[0002]

2. Description of the Related Art A conventional temperature control device of this type will be described with reference to FIG. Reference numeral 1 is a heater, and 2 is a driving means for driving the heater 1. A relay is generally used in a high power temperature control device such as an electric carpet. Reference numeral 3 is a temperature detecting means for detecting the temperature in the vicinity of the heater 1, and generates a temperature detection signal. Normally, a temperature sensitive element such as a thermistor detects temperature as a voltage value. Reference numeral 4 is a temperature setting means for setting a desired temperature. The control means 5 which receives the temperature detection means 3 and the first temperature setting means 4 drives the drive means 2 to energize the heater 1. FIG. 3 shows a drive determination block diagram in the control means 5. The control means 5 has a comparing means 6 for comparing the detected temperature of the temperature detecting means 3 with the set temperature of the first temperature setting means 4, and the detected temperature detected by the temperature detecting means 3 by the comparison of the comparing means 6 is the temperature setting. When the temperature is lower than the set temperature set by the means 4 (detection temperature <set temperature), the heater 1 is driven by the driving means 2. Once the detected temperature becomes higher than the set temperature (detected temperature ≧ set temperature), the control temperature is provided with hysteresis, and control is performed in consideration of the contact life of the driving means 2 such as a relay.

The operation of the above configuration will be described. The temperature of the heater 1 detected by the temperature detecting means 3 is compared with the control temperature set by the first temperature setting means 4. At this time, the driving unit 2 energizes the heater 1 until the temperature of the heater 1 becomes higher than the control temperature set by the first temperature setting unit 4. Then, when the temperature of the heater 1 becomes higher than the control temperature set by the first temperature setting means 4, the driving means 2 stops energization of the heater 1. Further, when the temperature of the heater 1 becomes lower than the control temperature set by the first temperature setting means 4, the driving means 2 starts energizing the heater 1 again. Such a series of operations are repeated to keep the temperature of the heater 1 such as the temperature controller constant.

FIG. 4 is an external view of an electric carpet. The electric carpet is composed of a main body 7 in which a heater 1 and a temperature detecting wire as a temperature detecting means 3 are arranged, and a controller box 8 in which a first temperature setting means 4 and a control board constituting the driving means 2 and the like are housed. Has been done. Further, as shown in FIG. 5, the temperature control device such as an electric carpet is provided with the room temperature detecting means 9
The temperature around the controller box 8 is detected.

Further, as shown in FIG. 6, the first
When the energization is started by the temperature setting means 4, the temperature setting is controlled to be high for a certain time regardless of the temperature setting, and the discomfort of the user due to the low surface temperature at the beginning of the energization is improved (hereinafter, this control is performed. That is called the initial rapid heating means).

Further, the user can use the second temperature setting means 1
When 0 is selected, the energization of the heater 1 is controlled via the driving means 2 at the set temperature of the second temperature setting means 10 according to the room temperature detected by the room temperature detecting means 9. Normally, the first temperature setting means 4 is used, and other heating equipment such as an air conditioner is also used. When the room temperature is sufficiently warmed up, the second temperature setting means 9 is used.
To set the second temperature setting state. Therefore, even if the set temperature of the second temperature setting means is lower than the set temperature of the first temperature setting means, the user does not feel discomfort, and the temperature setting is set to a low temperature, so that an energy saving effect can be obtained.

[0007]

However, the conventional structure as described above has the following drawbacks.

When the second temperature setting means 9 is operated at the start of energization to start energization in the second temperature setting state, the temperature setting becomes a low temperature fixed temperature setting with a low temperature, and the rising temperature of the carpet body is low. , Has the problem of feeling slimy.

When the energization is started in the first temperature setting state 4 at the start of the energization, the initial fast heating means keeps the first temperature for a predetermined time.
Control is performed at a temperature higher than that of the temperature setting means 4, but the main body 7
The second temperature setting means 9 while the temperature of the
In the case where the temperature is changed to the second temperature adjustment setting state, the initial rapid heating means is released, and the temperature of the carpet body 7 does not become sufficiently high, and there is a problem that it feels lukewarm.

Further, normally, the first temperature setting means 4 is used and other heating equipment such as an air conditioner is also used. When the room temperature is sufficiently warmed, the second temperature setting means 9 sets the second temperature. In order to set the state, when other heating equipment is not used, the room temperature is low, and it feels slimy unless the temperature of the carpet main body 7 is raised. Therefore, it is usually used in the first temperature setting state 4. There are many.

A first object of the present invention is to eliminate the delay in the rise of the main body temperature even when the second temperature setting means is selected, and to improve the discomfort during use.

A second object is to set the main body temperature according to the environment in which the carpet is used, and to supply a carpet that is more convenient to use.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the temperature control device of the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of the temperature control device of the present invention. Reference numeral 1 is a heater, and 2 is a driving means for driving the heater 1. Reference numeral 3 is a temperature detecting means for detecting the temperature in the vicinity of the heater 1, and generates a temperature detection signal. Normally, a temperature sensitive element such as a thermistor detects temperature as a voltage value. Reference numeral 4 is a first temperature setting means for setting a desired temperature. The control means 5 which receives the temperature detection means 3 and the first temperature setting means 4 drives the drive means 2 to energize the heater 1. When the energization is started by the first temperature setting means 4 at the start of energization, the user has an initial rapid heating means for controlling the temperature setting to be high for a fixed time regardless of the temperature setting, and a user due to a low surface temperature at the beginning of the energization start. Has improved the discomfort of.

Reference numeral 9 is a room temperature detecting means for detecting the room temperature near the controller box 8. Reference numeral 10 is a second temperature setting means, and when the second temperature setting means 9 is selected, the second temperature setting means 1 is used.
Temperature control is performed at a set temperature of 0. Second temperature setting means 9
The temperature control at the time of selection is the same as that at the time of selecting the first temperature setting means, the set temperature of the second temperature setting means 9 is compared with the detected temperature of the temperature detecting means 3, and when the detected temperature is lower than the set temperature (detection) When the temperature is lower than the set temperature, the heater 1 is energized via the driving means 2 to warm the main body. When the detected temperature is higher than the set temperature (detected temperature> set temperature), the energization of the heater 1 by the driving means 2 is stopped. Drive means 2
When the energization of the heater 1 is stopped at, the detected temperature gradually decreases, and the detected temperature falls below the set temperature (detected temperature <set temperature). When the detected temperature becomes lower than the set temperature, the heater 1 is energized again. This series of operations is repeated to maintain the temperature of the carpet.

As for the actual state of use of carpets, not only the carpet itself but also other heating devices are used together to heat the entire living room. In this way, the second temperature setting means 9 is selected when the carpet is used together with another heating device such as an air conditioner or a fan heater. At this time, the temperature of the living room (room temperature) is the temperature expected by the user (appropriate temperature), and even if the temperature of the carpet is set to a slightly low temperature, the user does not feel "slimy". Therefore, by setting the set temperature of the second temperature setting means 10 to be lower than that of the first temperature setting means 4, the user is neither warm nor cold (this is referred to as zero thermal sensation). And it saves energy.

Also, the first temperature control device of the present invention accelerates the rise of the main body temperature even when the second temperature setting means 10 is selected, as in the initial fast heating means when the first temperature setting means 4 is selected. Heater quick heating means 1 for eliminating discomfort of the wearer
1 for a fixed time from the time when the second temperature setting means 10 is selected,
Energization is performed at a set temperature that is higher than the set temperature of the second temperature setting means 10 by a certain temperature.

In the second temperature control means of the present invention, the room temperature detecting means 9 corrects the temperature setting of the heater rapid heating means 11 which is higher than the second temperature setting means 10 by a constant temperature.
The temperature detected by the room temperature detector 9 is a reference temperature (for example, 20
When the temperature is lower than (.degree. C.), the set temperature is set higher according to the degree of low temperature from the reference temperature, and when the temperature is higher than the reference temperature, the set temperature is set low according to the degree of high temperature from the reference temperature. This is shown in FIG. Further, not only the set temperature but also the set temperature obtained by correcting the set temperature at the room temperature detected by the room temperature detection unit 9 from the set temperature of the second temperature setting unit 10 when the second temperature setting unit 10 is selected is controlled. The room temperature detecting means 9 corrects the control time of the heater fast heating means 11 (hereinafter referred to as the heater fast heating time). Similarly to the set temperature, the energization time of the heater fast heating means 11 is set so that if the temperature detected by the room temperature detecting means 9 is lower than the reference temperature (for example, 20 ° C.), the heater fast heating time is lengthened and is higher than the reference temperature. If so, shorten the heater fast heating time.

Here, the operation of the heater rapid heating means 11 will be described in detail. The heater rapid heating means 11 improves the discomfort of the user due to the delay in the rise of the main body temperature at the start of energization as described above, but the room temperature is high when used together with other heating devices such as air conditioners and fan heaters. When the heater rapid heating means 11 is performed at this time, the main body temperature becomes a higher temperature than the set temperature of the second temperature setting means 10, so that the main body temperature once becomes a high temperature state and then the original set temperature of the second temperature setting means 10 is reached. Will be returned to. This is a feeling that the user feels “hot” in a high temperature state, and feels “hot” under the original temperature set by the second temperature setting means 10, so that the user feels “thin”. With this, even if the start-up is improved, discomfort occurs during use. In order to improve this, if the temperature detected by the room temperature detecting means 9 is lower than a certain temperature (for example, 20 ° C.), the temperature control by the heater rapid heating means 11 is eliminated, and if it is high, the heater rapid heating is performed. The means 11 controls the temperature. When the room temperature detected by the room temperature detecting means 9 is high, the heater quick heating means 11 does not control the temperature, so that the user does not feel uncomfortable. Further, when the detected room temperature is low, the temperature is controlled by the heater rapid heating means 11, so that the discomfort caused by the delay in rising is eliminated.

As shown in FIG. 8 as an environment in which the carpet is used, another heating device such as a fan heater is placed near the room temperature detecting means 9 in the controller box 8, and warm air such as the fan heater is supplied to the room temperature detecting means 9. When the detected temperature is affected, when the entire controller box 8 is kept warm by a cushion or the like, or when the room temperature detecting means 9 is kept warm even if not the entire controller box 8, the detected room temperature is on the high temperature side. I will detect it. At this time, even though the actual room temperature is low, the detected room temperature is detected to be high, so the heater rapid heating means 11 is released, and the start-up of the main body is delayed and it becomes uncomfortable. Therefore, the presence / absence of the heater rapid heating means 11 is determined not only by the temperature detected by the room temperature detecting means 9 but also by the temperature detected by the temperature detecting means 3 for detecting the temperature in the vicinity of the heater 1. The operation at this time is shown in (Table 1).

[0025]

[Table 1]

When the room temperature is lower than a certain temperature (for example, 20 ° C.), the operation is switched as follows according to the temperature detected by the temperature detecting means 3. When the temperature detected by the temperature detecting means 3 is a low temperature below a certain temperature (for example, 35 ° C.), both the room temperature and the main body temperature are low, so the temperature control by the heater rapid heating means 11 is performed, and the temperature control according to the room temperature is performed. I do. When the temperature detected by the temperature detecting means 3 is higher than 35 ° C., the main body temperature is already high even if the room temperature is low.
The temperature control of 1 is not performed. When the room temperature and the body temperature are both high, the room temperature and the body are already warm, so the heater rapid heating means 11
The temperature control is not performed. Even when the room temperature is high, when the body temperature is low, the user does not feel uncomfortable because the room temperature is high. For controlling the temperature of the carpet, it is determined that the controller box 8 is kept warm by another heating device and the room temperature detected by the room temperature detecting means 9 is highly likely to be erroneously detected. Although the room temperature is a high temperature, but the main body temperature is low, the temperature control by the heater rapid heating means 11 is performed. Since there is a possibility that the temperature detected by the room temperature detecting means 9 is erroneously detected as the set temperature of the heater fast heating means 11 at this time, the set temperature and the heater fast heating time are not corrected at the room temperature detected by the room temperature detecting means 9, Fixed setting and fixed time. Since the set temperature at this time is already high at room temperature, if the set temperature of the main body temperature is set high, it becomes uncomfortable and uncomfortable, so the set temperature is lowered (for example, 30 ° C.).

In this embodiment, the reference temperature and a certain temperature are set to 2
Although the temperature is 0 ° C., it goes without saying that the same configuration can be obtained even when a temperature other than 20 ° C. is used as the reference temperature. Further, although the reference temperature of the set temperature and the reference temperature of the heater rapid heating time are described as being the same, it is obvious that the different reference temperatures have the same configuration.

[0028]

As described above, according to the temperature control device of the first invention, the following effects can be obtained.

(1) By providing the heater fast heating means when the second temperature setting means is selected, the surface temperature expected by the user can be quickly raised when the temperature of the carpet main body is low, like the initial fast heating means.

(2) Further, by setting the temperature of the heater rapid heating means according to the room temperature, the overshoot of the surface temperature when the control temperature of the first temperature setting means is switched to the second temperature setting means. lose.

(3) When the room temperature detecting means is kept warm by a fan heater or the like, erroneous detection of the set temperature of the heater rapid heating means is prevented, and the surface temperature expected by the user is quickly raised.

Further, according to the temperature control device of the second invention, the following effects can be obtained. (4) The room temperature detecting means corrects the set temperature and time of the heater fast heating means to perform control according to the surrounding environment.
