Abstract

PURPOSE:To conduct electricity to heaters arranged in all heating faces of a substrate regardless of a selected heating face and to exterminate ticks surely and effectively by providing a heating face selecting means, a high-temperature heating means to heat the base body at a high temperature, etc. CONSTITUTION:In case, ticks are exterminated while a heating face 2a is selected and a set temperature 3 (35 deg.C) is set, when a high-temperature switch 23 is operated, a high-temperature heating means 24 operates and a setting circuit 11 of the 7 (50 deg.C) of a temperature setting means 8 is selected by an output S9. Set data are changed and inputted to comparing means 13a and 13b, a 3H meter 22 of a timer means 18 is selected by an output S7 of the means 24 and the outputs S5 and S6 of time data are inputted to control means 25a and 25b. An output S8 of the means 24 is inputted to a switching circuit 16 of a selecting means 15, outputs S3 and S4 of the circuit 16 becomes H and are inputted to the means 25a and 25b. Thus, the heating faces 2a and 2b are heated at the high temperature of 7 (50 deg.C) and the ticks can be exterminated, and when the means 18 counts the 3H, the electricity conduction is cut off.

Description

[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD OF THE INVENTION The present invention relates to wide rf IJ electric heaters such as electric carpets. One conventional technology for large area like electric carpet! 1c air heaters have the disadvantage that their power consumption is large, which increases the electricity bill. Ninth, it is proposed to select and heat only the minimum heating surface of the appliance body (where the person taking the heat is), depending on the number of people taking the heat or the position of the person taking the heat.
(Japanese Utility Model Publication No. 187217/1983) Recently, it has become clear that many mites breed parasitically on the underside of carpets, causing eczema on the human body, and countermeasures have been urgently needed. Dust mites can be killed by raising the temperature of the main unit to a high temperature of 50°C or higher, for example, and keeping it for 2 to 3 hours.However, as mentioned above, when one heating surface is selected, when a specific switch If you operate to raise the temperature, only the selected heating surface will become hot.
Dust mites move to the unselected heating surface on the low temperature side, and the effect is not obtained at all. (c) Problems to be Solved by the Invention The present invention reliably and effectively exterminates mites by energizing heaters disposed on all heating surfaces of the base, regardless of the selected heating surface. It is. B) Means for Solving the Problems The present invention provides a heating surface t-
a base body having a substrate, a heater disposed on each heating surface of the base body, and a selection means for selecting some or all of the heating surfaces and heating the selected heating surfaces by energizing the heaters. and high heating means for heating the base at a high temperature by energizing each of the heaters of the heating surface by the operation thereof, and the heating means is provided with the heating surface selected by the @ period selection means. Irrelevantly i! iIll'ill! A configuration is used in which electricity is supplied to the heaters disposed on all heating surfaces of the base. (3) In the case where, for example, one heating surface selected by the action selection means is being heated on the temperature side based on the set temperature,
By the operation of the high-temperature heating means, the heaters of all the heating surfaces are energized irrespective of the above-mentioned selected next heating surface to automatically reduce the temperature of the entire surface 7111 and raise the temperature of the substrate to exterminate the mites.

For example, if only the heating surface (2a) shown in Figure 2 and 9 is selected. , when heating, operate the changeover switch (141) to set only the output (S3) at the selection means to 7rJ, and at the same time operate the timer switch (L7) to set the desired energization time (for example, 5H).

Eventually, the timing operation by the timer means progresses and, for example, 4 hours and 30 minutes after the time has been counted, the notification means @ is driven, and after that, when the timekeeping operation for 5 hours is completed, the output (a) of the timer means a& becomes rLJ and the alarm means @ is driven. Cut off the 1! to the 1 heater (3a).Here, the heating surface (2a) mentioned above is selected and the set temperature '3 is set.

), (89) are canceled, and the setting data of the temperature setting means (83) and the output of the selection hand gius heat only the heating surface (2a) at the initially set temperature based on the initially selected content. In other words, the set temperature of the d degree setting means 4810 becomes '3. (35°C), and the output of the selection means (Is
S3] becomes "H" and the output (S4) becomes rLJ. In this example, the case where only the selected heating surface (2a) is heated is described, but the selected heating surface [2b]
The same applies even if the temperature is 7!11. Of course, the same applies even if both of the selected heating surfaces (21!, (2b) are heated at the same time!) Also, the number of heating surfaces may be three or four or more. In this embodiment, the high temperature by the high heating means is set at a set temperature level of 172 (5
0℃), but high temperature 1: Like the fifth factor, the set temperature level '7. (It is also possible to set the temperature to a level (55℃) that is higher than 45℃ for exterminating one mite.Although the present invention has been explained using a carpet as an example, it may also be applied to a wide-area heater such as a 1Jr or air blanket. (g) Effects of the Invention Since the present invention is constructed as described above, when any heating surface is selected from a plurality of heating surfaces, the present invention can be used for the purpose of exterminating mites. When the high heating means is operated, all heating surfaces are heated at a high temperature regardless of the heating surface selected above, so the selection means must be operated each time the high temperature is set. It is possible to exterminate mites reliably and easily without having to select the above-mentioned high heating means.Furthermore, after the above-mentioned operation of the high heating means, the timer means performs a total of 1'l? for a predetermined period of time, and then the high heating means Since the operation is stopped, the high heating state does not continue unnecessarily for a long time and wasteful power consumption can be suppressed.Furthermore, when the high heating means is activated while the timer means is in operation, the high heating means is activated. When the operation is stopped, the initially selected heating surface is controlled based on the initially set desired temperature. It has many advantages such as no need to select and set a set temperature.
