Abstract

PURPOSE:To promote the convenience for use by providing a means for changing a setting in a temperature-setting means for a specified period of time, a means for making the changed period of time variable, and a means for changing the temperature for judgment by a temperature-judging means. CONSTITUTION:A temperature-detective means 3 detects the temperature of a heating means 2, and a temperature-judging means 5 judges the temperature detected by the temperature detective means 3 in respect of whether it requires powerful start or not. A temperature- controlling means 6 controls the heating means 2, and a temperature-setting means 7 sets the temperature controlled by the temperature-controlling means 6. A means 8 for changing the setting of temperature changes the temperature set by the temperature-setting means 7. A means 9 for changing the temperature for judgement changes the temperature judged by the temperature-judging means 5. A means 12 for making the time for a set temperature variable changes the time for which a high temperature is set during powerful start. When the user desires powerful start to be easy to be used in starting the power supply, the temperature for judgement is lowered by the use of the means 9 for changing the temperature for judgment; the means 9 for changing the temperature for judgment outputs a signal for lowering the temperature for judgment to the temperature-judging means 5 so that the temperature for judgment in respect of whether there should be powerful start or not declines. When powerful start is not desired to be easy to be used, the temperature for judgment to decide whether there should be powerful start or not rises. The temperature for judgment for powerful start can be varied and conditions can be selected for powerful start. Thus this method enhances the convenience for use.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to heating devices such as electric carpets.

Conventional technology This will be explained using a conventional electric carpet as an example.

As shown in Figure 6, when the i11 electricity of an electric carpet starts, in order to improve the temperature rise of the carpet body, even if the set temperature is low, the set temperature is controlled to be higher for a certain period of time after the start of electricity supply. .

This kind of control is called strong start control.

There are two methods of strong start control: a method of increasing the set temperature for a certain period of time, and a method of varying the time period during which the set temperature is kept high.

Strong start control is effective when the temperature of the carpet body is low, but if strong start control is performed when the carpet body is warm, such as when re-energizing, the body temperature will become too high and it will feel hot, making it difficult to use. For this reason, the main body temperature at the start of energization is detected and strong start control is performed only when the main body temperature is low.

Problems to be Solved by the Invention However, since the temperature of the detection line is detected with the above configuration and the presence or absence of a strong start is determined at a constant judgment temperature, the room temperature is low and the temperature rise is slow, and Even when it is better to apply a strong start when the power is re-energized, if the main body is warm to some extent, the strong start will not be applied.
It is inconvenient to use because it does not heat up easily.

If the judgment temperature is set low in order to give priority to temperature rise, a strong start is applied even when the room temperature is high and a strong start is not required, resulting in a problem in that the device gets hot and is not convenient to use.

The present invention solves the above-mentioned problems and relates to an easy-to-use warming device that changes the determination level of whether or not a strong start is to be started when the electric carpet is reenergized.

Means for Solving the Problems: A heating means, a temperature detection means for detecting the temperature of the heating means, a temperature control means for controlling the heating means, and a temperature setting means for setting the temperature of the heating means, temperature setting means for determining that the temperature of the temperature detection means is below a certain temperature when the heating means starts to be energized; a means for changing the setting of the temperature setting means for a certain period of time based on the output thereof; and a time period for changing the temperature setting means. and means for changing the judgment temperature of the temperature judgment means.

Effect of the Invention With the above-described configuration, the strong start start determination level is arbitrarily changed by the changing means at the time of starting energization.

Alternatively, the temperature increase rate of the temperature detection means or the room temperature is detected and changed. When the temperature rise rate is low or the room temperature is low, the judgment level is lowered to make it easier to perform a strong start. Furthermore, when the rate of temperature rise is high or the room temperature is high, the determination level is increased to optimize the strong start determination level.

EXAMPLE A first example of the present invention will be described below with reference to FIGS. 1 and 2. In Fig. 2, this is the main body of an electric carpet, and a controller 4 for controlling this electric carpet is connected. 2 is a heating means, and 3 is a temperature detection means for detecting the temperature of this heating means.

In FIG. 1, 2 is a heating means, 3 is a temperature detection means for detecting the temperature of this heating means, and 4 is a controller. 5 is a temperature determining means for determining whether the temperature of the temperature detecting means requires a strong start; 6 is a temperature controlling means for controlling the heating means;
7 is a temperature setting means for setting the control temperature of the temperature control means;
Reference numeral 8 denotes a temperature setting changing means for changing the set temperature of the temperature setting means. , 9 is a judgment temperature changing means for changing the judgment temperature of the temperature judgment means 5. Reference numeral 12 denotes a temperature setting time variable means for changing the time period during which the set temperature is kept high during a strong start.

The operation in the above configuration will be explained.

The operation of changing the determination temperature for a strong start by the determination temperature changing means 9 at the time of starting energization will be described below. If the user wants to make it easier to apply a strong start when starting energization, use the determination temperature changing means 9 to lower the determination temperature.

The determination temperature changing means 9 outputs a signal to lower the determination temperature to the temperature determination means 5, and the determination temperature for determining whether or not a strong start has started is lowered.

When the user wants to make it difficult for the user to perform a strong start, the determination temperature changing means increases the determination temperature. Judgment temperature changing means 9
outputs a signal to the temperature determination means 5 to increase the determination temperature,
The temperature for determining whether or not a strong start has started becomes higher.

Next, a description will be given of the strong start operation based on the relationship between the temperature detecting means temperature and the determination temperature at the time of starting energization.

The operation will be described when re-energization is started midway when the temperature of the temperature detection means is higher than the determination temperature for starting a strong start.

Since the temperature of the temperature detecting means 3 is higher than the determination temperature for starting a strong start, the temperature determining means 5 outputs a signal indicating no strong start to the temperature setting changing means 8. Since the temperature setting change means 8 does not have a strong start, no change output is output to the temperature setting means.

Temperature control is performed using the settings of the temperature setting means.

The operation when re-energization is started midway when the temperature of the temperature detection means is lower than the determination temperature for starting a strong start will be described.

Since the temperature of the temperature detecting means 3 is lower than the determination temperature for starting a strong start, the temperature determining means 5 outputs a signal indicating that a strong start is present to the temperature setting changing means 8.

The temperature setting changing means 8 makes the setting of the temperature setting means 7 high for a certain period of time to perform a strong start operation. When the judgment temperature is low, it is advantageous to use a strong start to improve the rise. It is effective to change the judgment temperature depending on conditions such as the size of the carpet and the room temperature.

The second example will be described below.

The operation of changing the strong start determination temperature based on the temperature rise rate immediately after the start of energization in FIG. 3 will be described below.

Immediately after the start of energization, the temperature increase rate detection means 10 detects the temperature increase rate of the temperature detection means 3. When the temperature increase rate is high, a change signal is output to the judgment temperature changing means 9 to increase the judgment temperature. The determination temperature changing means 9 outputs a signal to the temperature determination means 5 to increase the determination temperature, and the determination temperature for determining whether or not a strong start has started becomes higher.

When the temperature increase rate is low, a change signal is output to the judgment temperature changing means 9 to lower the judgment temperature. The determination temperature changing means 9 outputs a signal to lower the determination temperature to the temperature determination means 5, and the determination temperature for determining whether or not a strong start has started is lowered.

The determination temperature at the start of energization and the strong start operation are the same as in the first embodiment.

The third example will be described below.

In FIG. 4, 2 is a heating means, 3 is a temperature detection means for detecting the temperature of this heating means, and 4 is a controller. 5 is a temperature determining means for determining the temperature of the temperature detecting means, 6 is a temperature control means for controlling the heating means, 7 is a temperature setting means, and 8 is a temperature setting changing means of the temperature setting means. 9 is a judgment temperature changing means, and 11 is a room temperature detecting means for detecting the room temperature.

First, the relationship between the room temperature and the temperature for determining the presence or absence of a strong start will be explained. When the room temperature is high, there is less heat dissipated from the surface of the electric carpet, and it takes less time to reach the set temperature. bad. Therefore, the determination temperature for a strong start is high, and it is desirable to avoid a strong start as much as possible.

On the other hand, when the room temperature is low, a large amount of heat is radiated from the electric carpet, and it takes time to reach the set temperature.If you do not use a strong start, the temperature will not rise easily, making it difficult to use. Therefore, the judgment temperature for a strong start is low, and it is desirable to apply a strong start as much as possible.

Next, the operation of changing the strong start determination temperature based on the difference in room temperature at the time of starting energization will be described below. The room temperature detecting means 11 detects the room temperature at the start of electricity supply. When the room temperature is high, a change signal is output to the judgment temperature changing means 9 to raise the judgment temperature. The determination temperature changing means 9 outputs a signal to the temperature determination means 5 to increase the determination temperature, and the determination temperature for determining whether or not a strong start has started becomes higher.

When the room temperature is low, a change signal is output to the judgment temperature changing means 9 to lower the judgment temperature. The determination temperature changing means 9 outputs a signal to lower the determination temperature to the temperature determination means 5, and the determination temperature for determining whether or not a strong start has started is lowered.

The determination temperature at the start of energization and the strong start operation are the same as in the first embodiment.

Effects of the Invention As described above, the heating device of the present invention provides the following effects. Since the temperature for determining a strong start can be varied, the starting conditions for a strong start can be selected, making it easy to use.

In item (2), depending on the temperature rise of the main body immediately after starting energization,
Since the strong start judgment temperature is changed, when the temperature rises slowly, the strong start judgment level is lowered, and when the temperature rises quickly, the strong start judgment level is set high, thereby setting the optimum strong start level. settings can be made.

In item (3), by detecting the room temperature and changing the strong start level, the strong start level can be changed at the start of energization, so a more fine-grained level setting for strong start determination can be made.
