  By the way, in winter, the heating device is operated for warming to increase the external atmospheric temperature of the device, and in summer (particularly during the rainy season), the heating device is operated to dry the objects to be dried.

  In the above-described conventional heating apparatus, since the control mode is one way, when the heating intensity set by the strength setting means is the same, the heating value in the heating means is the same regardless of whether it is summer or winter. This can lead to overheating in summer when the external ambient temperature is high compared to winter when the external ambient temperature is low, and underheating compared to summer when the external ambient temperature is low. This caused heating variations.

  The present invention was invented in view of the above-described conventional problems, and the object of the present invention is to provide a heating device that does not cause variation in heating due to a difference in external ambient temperature. It is what.

  In order to solve the above problems, the present invention has the following configuration.

  Heating means, temperature detecting means for detecting the ambient temperature, intensity setting means for setting the intensity of heating, and control means for controlling the amount of heat generated by the heating means based on the intensity of heating set by the intensity setting means And comprising. The control means changes the control mode so that the amount of heat generated by the heating means at the set arbitrary intensity varies according to the external ambient temperature.

  In addition, when the predetermined temperature is set as a threshold value of the external atmosphere temperature, and the external atmosphere temperature detected by the temperature detection means exceeds / above the predetermined threshold value, the control mode is set to the low temperature mode and is detected by the temperature detection means. It is also preferable to set the control mode to the high temperature mode when the external ambient temperature to be performed is equal to or less than the predetermined threshold value.

  By changing the control mode according to the external ambient temperature, the present invention always sets the heating intensity with the same feeling throughout the year without being aware of whether it is winter or summer or the external ambient temperature. Thus, it is possible to eliminate the variation in heating caused by the difference in external ambient temperature.

It is an external atmosphere temperature-target temperature figure explaining the method of the correction | amendment of control in one Embodiment of this invention. It is a schematic block diagram of a heating apparatus same as the above. It is a general-view figure of a heating apparatus same as the above. It is a front view of the operation part of a heating apparatus same as the above. It is a figure of external ambient temperature-target temperature explaining the method of the change of control in other embodiment.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIG. 2, the heating device A includes a heating means 1, a temperature detection means 2, a strength setting means 3, and a control means 4, and in this embodiment, as shown in FIG. 3. It is the heating apparatus A in the shape of a panel. Reference numeral 8 in FIG. 3 is a clothesline, and reference numeral 9 is an object to be heated.

  Examples of the heating means 1 include those using warm water as a heat medium, electric heaters, combustors, and the like. In this embodiment, the heating means 1 is a PTC heater, and the PTC heater is embedded in the panel-shaped heating apparatus A.

  The strength setting means 3 is for setting the intensity of heating. The intensity of heating is set at a plurality of levels, and in this embodiment, there are five levels from the weakest level 1 to the strongest level 5 of the heating intensity. The intensity of heating may be set not continuously but continuously. This strength setting means 3 may be provided in the main body provided with the heating means 1 of the heating apparatus A, but in this embodiment, as shown in FIG. 4, the main body is connected to the main body via a communication means (not shown). The communication unit 5 may be provided, and the communication means may be either wireless or wired. Further, the operation unit 5 is provided with a strength display unit 6 for displaying a set level of heating intensity and an on / off switch 7 for turning on / off the heating.

  The temperature detection means 2 detects the external atmospheric temperature of the place where the heating device A is used, and normally detects the temperature of the room where the heating device A is used. This temperature detection means 2 is composed of a thermistor, a thermocouple, etc., and may detect the temperature directly by exposing it to the indoor air that is the temperature detection target, but indirectly detects the temperature without exposing it to the indoor air. You may do it.

  For example, the temperature of the external external atmosphere is detected from the rate of decrease in the temperature of the electrical device when the electrical device that generates heat by energization is stopped, for example. Preferred examples of the electric device that generates heat when energized include a relay and a DC power supply component, but may be an operation switch, a display unit, a transmission / reception unit, other resistance elements, or the like. The temperature detected by the temperature detection means 2 is affected by the external ambient temperature. When energization of the electrical device is stopped, heat generation in the electrical device stops and the temperature of the electrical device decreases, but this rate of decrease is slow when the external ambient temperature is high, and the rate of decrease is fast when the external ambient temperature is low. For this reason, the external ambient temperature can be detected by detecting the descending speed.

  The control means 4 is composed of a microcomputer and controls the amount of heat generated by the heating means 1 based on the heating intensity set by the strength setting means 3.

  In accordance with the heating intensity levels 1 to 5, the heating means 1 is controlled so as to vary the amount of heat generated. However, in the present invention, the amount of heat generated by the heating means at an arbitrary set intensity is further controlled. It is characterized in that the control mode is changed so as to vary depending on the ambient temperature.

  In the present embodiment, as shown in FIG. 1, an external ambient temperature of 20 ° C. is used as a threshold value, and when the external ambient temperature is 20 ° C. or higher, a low temperature control mode (hereinafter referred to as a low temperature mode) is performed. When the temperature is lower than ° C., a high temperature control mode (hereinafter, referred to as a high temperature mode) is performed. In the low temperature mode, the target temperature for level 1 is 30 ° C., the target temperature for level 2 is 35 ° C., the target temperature for level 3 is 40 ° C., the target temperature for level 4 is 46 ° C., and the target temperature for level 5 is 51 ° C. In the high temperature mode, the target temperature for level 1 is 35 ° C., the target temperature for level 2 is 41 ° C., the target temperature for level 3 is 48 ° C., the target temperature for level 4 is 54 ° C., and the target temperature for level 5 is 60 ° C. . The control unit 4 controls the amount of heat generated by the heating unit 1 so that the target temperature is reached. Here, the target temperature is an index for determining the amount of heat generated by the heating means 1 provided for convenience during design, and may not be the external ambient temperature. The amount of heat generated by the heating unit 1 is determined based on the target temperature, and the amount of heat generated by the heating unit 1 increases as the target temperature increases.

  For example, in the winter, for heating, a heated object such as a person in front of the heating device A is heated or the external atmosphere temperature is increased. In summer (especially during the rainy season), a heated object 9 such as a towel is disposed in front of the panel-shaped heating device A (in the heat radiation direction) to dry the heated object 9. When the user sets the heating intensity in the summer in the same way as in the winter, the external atmosphere temperature is higher than that in the winter. Therefore, in the case of the conventional heating apparatus A, the heating means 1 when the heating intensity is the same. The amount of heat generated becomes larger than necessary, resulting in variations in heating.

  In the present invention, since the amount of heat generated by the heating means 1 is made different according to the external ambient temperature as described above, the user can use it for one year without being aware of whether it is winter or summer or the external ambient temperature. It is possible to prevent variations in heating caused by differences in the external ambient temperature by simply setting the heating intensity with the same feeling throughout.

  There may be a plurality of threshold values. In this case, the high temperature region and the low temperature region sandwiching the threshold value are controlled so that the high temperature region has a lower temperature at the same intensity setting than the low temperature region.

  In addition, the ON / OFF switch 7 is provided with a control display unit 61 capable of flashing. The control display unit 61 lights or flashes in the high temperature mode, and the control display unit 61 flashes or lights in the low temperature mode. You may make it do. Thereby, the user can know whether the high temperature mode is performed or the low temperature mode is performed.

  In the upper embodiment shown in FIG. 1, two types of control are performed using the external ambient temperature of 20 ° C. as a threshold value. However, in the other embodiments shown in FIG. 5, the target temperature is continuously set to any external ambient temperature. The control mode has been changed to change.

  When the external ambient temperature is 0 ° C, the target temperature for level 1 is 39 ° C, the target temperature for level 2 is 45 ° C, the target temperature for level 3 is 51 ° C, the target temperature for level 4 is 58 ° C, and the target temperature for level 5 Is 64 ° C.

  When the external ambient temperature is 10 ° C, the target temperature for level 1 is 34 ° C, the target temperature for level 2 is 40 ° C, the target temperature for level 3 is 47 ° C, the target temperature for level 4 is 53 ° C, and the target temperature for level 5 Is 59 ° C.

  When the external ambient temperature is 20 ° C, the target temperature for level 1 is 33 ° C, the target temperature for level 2 is 38 ° C, the target temperature for level 3 is 43 ° C, the target temperature for level 4 is 49 ° C, and the target temperature for level 5 Is 54 ° C.

  When the external ambient temperature is 30 ° C., the target temperature of level 1 is 31 ° C., the target temperature of level 2 is 36 ° C., the target temperature of level 3 is 41 ° C., the target temperature of level 4 is 46 ° C., and the target temperature of level 5 Is 51 ° C.

When the external ambient temperature is between 0 ° C. and 10 ° C., for example, the target temperature of level n (n = 1, 2, 3, 4, 5) is the target temperature Tn of level n with the external ambient temperature of 0 ° C. _Assuming that the external ambient temperature changes linearly from ₀ to the target temperature Tn ₁₀ of the level n of 10 ° C., the target temperature T is determined from the detected external ambient temperature t.
Calculated as T = (Tn ₁₀ −Tn ₀ ) / 10 × (t−0) + Tn ₀ .

Further, when the external ambient temperature t is between 10 ° C. and 20 ° C., the target temperature T of the level n at which the external ambient temperature is 20 ° C. is Tn ₂₀ , and the target temperature T is set as described above.
Calculated as T = (Tn ₂₀ −Tn ₁₀ ) / 10 × (t−10) + Tn ₁₀ .

Similarly, when the external ambient temperature t is between 20 ° C. and 30 ° C., the target temperature T of the level n at which the external ambient temperature is 30 ° C. is Tn ₃₀ , and the target temperature T is
Calculated as T = (Tn ₃₀ −Tn ₂₀ ) / 10 × (t−20) + Tn ₂₀ .

Similarly, when the external ambient temperature t is between 30 ° C. and 40 ° C., the target temperature T is set to Tn ₄₀ with the target temperature of the level n at which the external ambient temperature is 40 ° C.
T = (Tn ₄₀ −Tn ₃₀ ) / 10 × (t−30) + Tn ₃₀

  In this way, finer control is possible.
