Abstract

PURPOSE:To obtain an electric carpet adapted to adjust and set its heating temperature range matching the living pattern of occupants, by the manipulation of change over switch. CONSTITUTION:A controller 12 having a temperature adjusting circuit internally is provided with a temperature adjusting volume 13 for adjusting the temperature of carpet body and a change over switch 14 adapted to vary the temperature range to match the living pattern of occupants. A voltage comparator 17 functions to compare voltages respectively fed by the temperature adjusting volume 13 and by a surface temperature detector 16, and transmit an ON-OFF control signal to a power circuit 18. The change over switch 14 is internally provided with contacts (a), (b), (c) and (d) having voltages respectively corresponding to the temperatures of 45 deg.C, 40 deg.C, 30 deg.C and 25 deg.C. While an occupant is sitting on the carpet, the temperature adjusting range can be set in the range of 25-30 deg.C by changing the change over switch 14 to a position ''Sit A''. On the other hand, the temperature range can be adjusted to the range 40-45 deg.C and 30-45 deg.C respectively while the occupant sits on a chair (with the change over switch at a position ''Sit B'') and is standing for works (a position ''C'').

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric carpet whose temperature control range can be changed according to the living pattern of the occupant.

Conventional structure and problems Generally, electric carpets have a heater and a temperature sensor installed in their main body, and are not suitable for laying on the floor of the area to be heated. It's being carried away.

Figure 1 shows a configuration diagram of a conventional electric carpet, where 1 shows the electric carpet, and 2 shows the temperature side of the electric carpet that keeps the surface temperature of the electric carpet body 1 at an appropriate temperature.
A controller 3 that includes a circuit and a power supply circuit is a temperature control volume that controls the temperature of the electric carpet main body 1.

In the above-mentioned conventional configuration, the occupant has no choice but to adjust the temperature control volume 3 and the electric carpet main body 1.
can be brought to an appropriate temperature.

FIG. 2 shows the relationship between the surface temperature of the electric carpet and the temperature control notch in the conventional example. By adjusting and turning the temperature control volume 3 and setting the temperature control scale to an arbitrary position, the occupant can adjust the surface temperature of the electric carpet to a temperature that makes him feel comfortable.

However, the surface temperature of electric carpets that residents feel comfortable with varies greatly depending on their living patterns.For example, when residents live in a sitting or lying position, The surface temperature of an electric carpet that feels comfortable is 2 because direct conduction heat reaches it.
The temperature will be 5-30°C. However, when living in a standing or sitting position, the comfortable surface temperature is 40 to 45°C because radiant heat is used mainly to warm the body.

When a resident performs standing work, the comfortable surface temperature varies greatly depending on the intensity of the work.
A temperature control range of 45°C is required. In this way, there are multiple temperature control ranges in which residents feel comfortable, and these vary depending on their lifestyle patterns.

Therefore, in conventional electric carpets, the selection of the comfortable surface temperature was left to the occupants, and the occupants themselves had to adjust the temperature according to their lifestyle patterns, making them inconvenient to use. Additionally, in the case of conventional electric carpets, there is a possibility that residents may accidentally warm themselves for a long time on carpet soil with a surface temperature of 40°C or higher, in which case,
Purpose of the Great Low Temperature Invention The purpose of this invention is to inventively eliminate the above-mentioned drawbacks of the conventional technology, and to allow electric carpets to operate comfortably according to daily life patterns, and to reduce the risk of low temperature burns. .

Structure of the Invention In order to achieve the above object, the present invention is provided with a changeover switch that selectively changes over a plurality of temperature control ranges of the electric carpet main body according to the living pattern of the occupant.

With the above configuration, the temperature adjustment range can be set according to the resident's lifestyle pattern by simply operating the changeover switch.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 to 6.

FIG. 3 shows the structure of an electric carpet according to an embodiment of the present invention, in which numeral 11 is an electric carpet main body, and numeral 12 is a heating system for keeping the surface temperature of the electric carpet main body 11 at an appropriate temperature. 13 is a temperature control volume in all rows 9 for temperature control of the electric carpet main body 11, which is provided in the controller 12. Reference numeral 14 denotes a changeover switch for changing the temperature control range according to the living pattern of the resident. Like the temperature control volume 13, this changeover switch 14 is also provided in the controller 12, making it very convenient in terms of usability. It is something.

FIG. 4 is a system (goods) block diagram in the above embodiment,
Components with the same numbers as those in FIG. 3 indicate the same components, and therefore the description thereof will be omitted. 15 is a reference voltage generator that generates a reference voltage; 16 is the electric carpet main body 1;
It is a surface temperature detector that generates a voltage according to the surface temperature of the n1 (internally installed in the n1). 17 is a voltage comparator that compares the voltages of the temperature control volume 1370 and the like with the voltages from the surface temperature detector 16 and sends an ON-OFF damping 0 signal to the power supply circuit 18. 1, said selector switch 14
Contact points a, b, c, aiq inside f14
5℃, 40℃.

These contacts have voltages corresponding to 30°C and 26°C, and contacts e and f [are connected to both ends of the temperature control volume 13, and are connected to both ends of the temperature control volume 13, so that the occupant can adjust the temperature according to the living pattern of sitting position A or i-position standing work C. When the changeover switch 14 is operated,
In the case of a person, C and e, d and f are short-circuited, in the case of B, a and e, and b and f are short-circuited, and in the case of C, ia and e, and c and f are short-circuited. In addition, 19+ 20+ 2
1 + 22, 23 are the n contacts a, b,
This is an appropriate resistance to maintain c and d at a predetermined voltage.

In the above configuration, for example, when the resident lives in a sitting position, by switching the changeover switch 14 to the sitting position A, the temperature adjustment range is increased to 26° as shown in FIG.
The temperature can be set at ~3oC. 1. Similarly to Part 1, the temperature can be adjusted within the range of rJ, 40 to 45°C for sitting position B, and 30 to 45°C for standing work C.

As described above, the inventive electric carpet has a changeover switch that selectively switches between multiple temperature adjustment ranges according to the resident's lifestyle pattern, allowing the resident to adjust the temperature according to the lifestyle pattern of the resident. There is no need to do this, and all you have to do is turn the changeover switch. Therefore, the usability is greatly improved, and even the changeover switch can be set accurately, reducing the risk of low-temperature burns caused by prolonged heating. be.
