Description

  The present invention relates to an electrical appliance.

  As a conventional electric anchor, there is one that is configured as a flat thin plate and can be kept warm by putting a foot on the bed in a sleeping state (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 63-74113 Japanese Utility Model Publication No. 61-142210

  However, the electric anchor described in Patent Document 1 has a problem that there is a risk of low-temperature burns when the legs are put on for a long time.

  The present invention has been made paying attention to such a problem, and an object thereof is to provide an electrical appliance capable of preventing low-temperature burns.

  In order to achieve the above object, an electric appliance according to the present invention includes a plate-like electric heating element, a housing member, a pressure sensor, and a temperature control unit, and the plate-like electric heating element is connected to a power source to generate heat. The housing member is made of a resilient net, is entirely plate-shaped and has a housing portion therein, the plate-like electric heating body is housed in the housing portion, and the pressure sensor is Provided inside the housing member to detect a pressure in the thickness direction applied to the housing member, and the temperature control unit lowers the temperature of the plate-shaped electric heating body according to the magnitude of the pressure detected by the pressure sensor. The temperature is adjustable.

  The electric anchor according to the present invention is used by putting a foot on a plate-shaped accommodation member in a lying state. The feet can be kept warm by connecting the plate-like electric heating element to a power source to generate heat. Since the housing member is made of a resilient net, the feeling of placing the foot is soft and the foot is less likely to get tired. Since the plate-like electric heating element is accommodated in the accommodation portion made of a net, it is possible to prevent the feet from directly touching the plate-like electric heating element and to prevent low-temperature burns caused by long-term use. Further, since the housing member is made of a net, the heat from the plate-like electric heater can be diffused efficiently. Since the electric heating element according to the present invention has the plate-like electric heating element accommodated in the accommodating portion, it can be used along the horizontal direction, or can be used upright in the vertical direction.

  As the plate-shaped electric heating element, a commercially available plate-shaped electric heater may be used in addition to a commercially available line surface heating element or a sheet heating element. The housing member is preferably covered with a cloth cover or the like.

In the electric anchor according to the present invention, when a pressure in the thickness direction is applied to the housing member by placing a foot on the housing member, the pressure sensor detects the pressure and the temperature control unit detects the temperature of the plate-like electric heater. Can be adjusted to lower. As a result, the weight of the foot makes the accommodating member made of an elastic net thin, and when the foot approaches the plate-like electric heating body, the pressure detected by the pressure sensor increases, and the temperature of the plate-like electric heating body decreases. For this reason, it can be prevented that the foot is too close to the plate-like electric heating body and the heating temperature of the foot rises to feel hot or cause low-temperature burns. Therefore, regardless of the weight of the foot or the weight applied to the housing member, it is possible to adjust the temperature to a comfortable temperature while keeping the feeling of putting the foot elastic and soft.
In the electric appliance according to the present invention, the temperature controller may turn off the power source of the plate-shaped electric heating element when the pressure detected by the pressure sensor is equal to or larger than a predetermined level. In this case, it is possible to further prevent low temperature burns and breakdowns.

  The electric anchor according to the present invention has a power switch and a light emitting part, and the power switch has a switch case having a light transmitting part and is connected between the plate-like electric heating body and the power source, A light emitting unit is connected to the power source through the power switch so as to be switched on / off in accordance with the on / off state of the plate-shaped electric heating element, and is provided inside the switch case so as to emit light to the outside through the light transmitting unit. It may be done. In the configuration having the power switch and the light emitting unit, the on / off state of the plate-like electric heating body can be seen at a glance by confirming the light emission of the light emitting unit. Since the light emitting part shines and stands out in a dark room, it is possible to prevent the power switch from being forgotten to be turned off. Since the light emitting unit is provided inside the switch case of the power switch, it is possible to confirm the on / off state of the plate-shaped electric heating body as the power switch is operated.

  According to the present invention, it is possible to provide an electric appliance that can prevent low-temperature burns.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the electric anchor 1 includes a plate-shaped electric heating element 2, a housing member 3, an electric cord 4, an intermediate switch 5, and a cover 6.

  The plate-shaped electric heating element 2 is made of a commercially available line surface heating element having a rectangular plate shape. The plate-like electric heater 2 has a configuration that generates heat when connected to a power source. The plate-like electric heating element 2 has a sheet-like rubber attached to the front surface and an aluminum foil attached to the back surface to uniformly transmit heat. In addition, the plate-shaped electric heating body 2 may be enclosed in the bag made from aluminum foil instead of sticking aluminum foil. Use a bag with a hole for air venting.

  The housing member 3 is made of a long iron net and has elasticity. The housing member 3 has a rectangular plate shape as a whole, is slightly larger than the plate-like electric heating body 2, and has a housing portion 3a therein. The accommodating member 3 accommodates the plate-like electric heater 2 in the accommodating portion 3a.

  One end of the electric cord 4 is connected to the side of the plate-like electric heating body 2 through the mesh of the housing member 3. The electric cord 4 has a plug 4a that can be connected to the electric outlet at the other end in order to take power from an electric outlet provided on the wall surface of the house. The electric cord 4 can supply electricity from the power source to the plate-like electric heater 2.

  The intermediate switch 5 has a switch case 5c having a display window 5a for displaying on / off of the power source and a circular light transmitting portion 5b. The intermediate switch 5 is provided at the center of the electric cord 4 and is connected between the plate-like electric heating element 2 and the power source. As shown in FIG. 2, the intermediate switch 5 includes a power switch 7, a light emitting unit 8, and a resistor 9 inside a switch case 5c.

  The power switch 7 is a push-type switch that can be switched on and off. The power switch 7 has two interlocking terminals and is connected in series to the two terminals of the plug 4a. The light emitting unit 8 is formed of a red light emitting diode, and is connected in parallel to the plate-like electric heater 2 on the plate-like electric heater 2 side from each power switch 7. The light emitting unit 8 is connected to a power source via the power switch 7 so as to be switched on / off in accordance with the on / off of the plate-like electric heating element 2. The light emitting part 8 is disposed inside the light transmitting part 5b and is provided so as to be able to emit light through the light transmitting part 5b. The resistor 9 is connected in series with the light emitting unit 8 in order to adjust the current flowing through the light emitting unit 8.

  The cover 6 is made of cloth and covers the housing member 3. The cover 6 has an opening with a fastener, and the accommodating member 3 can be taken in and out from the opening.

  In a specific example, the plate-shaped electric heating element 2 has a width of 320 mm, a depth of 260 mm, a rated voltage of 100 V, a power consumption of 21 W, and a surface temperature of 50 degrees at the maximum. The light emitting unit 8 has a power consumption of 0.002W. The resistor 9 is 25 kΩ.

Next, the operation will be described.
The electric anchor 1 is used by putting a foot on the plate-like accommodation member 3 in a lying state. The feet can be kept warm by inserting the plug 4a into an electrical outlet and connecting the plate-like electric heating element 2 to a power source to generate heat. Since the housing member 3 is made of a resilient net, the feeling of putting a foot on it is soft and the foot is less likely to get tired. Since the plate-like electric heating element 2 is accommodated in the accommodation portion 3a made of a net, it is possible to prevent the feet from directly touching the plate-like electric heating element 2 and to prevent low-temperature burns caused by long-time use. Moreover, since the accommodating member 3 consists of a net | network, the heat from the plate-shaped electric heating body 2 can be spread | diffused efficiently. In addition, since the electric anchor 1 is accommodated and protected by the plate-like electric heater 2 in the accommodating portion, it can be used along the horizontal direction or can be used in the vertical direction.

  The electric anchor 1 confirms the light emission of the light-emitting portion 8 so that the on / off state of the plate-like electric heater 2 can be known at a glance. Since the light emitting unit 8 shines and stands out in a dark room, it is possible to prevent the power switch 7 from being forgotten to be turned off. Since the light emitting unit 8 is provided inside the switch case 5c, it is possible to confirm the on / off of the plate-shaped electric heating element 2 as the power switch 7 is operated.

  In addition, as a result of performing the continuous use test for 3 days, the temperature of the intermediate switch 5 increased only to 40 degrees at the maximum. From this result, it can be seen that the electric anchor 1 has high safety without causing a burn or a fire due to heat generated by the light emitting portion 8 or the resistor 9 during use.

  As shown in FIG. 3, the electric anchor 1 may have a pressure sensor 10 and a temperature control unit 11. The pressure sensor 10 is provided inside the housing member 3 so as to detect pressure in the thickness direction applied to the housing member 3. The temperature control unit 11 can adjust the temperature so as to lower the temperature of the plate-shaped electric heater 2 according to the magnitude of the pressure detected by the pressure sensor 10. The pressure sensor 10 has a thin plate shape and is disposed in the vicinity of the center of the surface of the plate-like electric heating body 2 inside the housing member 3. The temperature control unit 11 is provided on a side portion near one corner of the plate-like electric heating body 2, and is connected to the pressure sensor 10 via the cable 12. The electric cord 4 is connected to the temperature control unit 11.

  In the configuration having the pressure sensor 10 and the temperature control unit 11, when the electric anchor 1 puts a foot on the housing member 3 and pressure in the thickness direction is applied to the housing member 3, the pressure is applied to the pressure sensor. 10 can be detected and adjusted by the temperature control unit 11 to lower the temperature of the plate-like electric heating element 2. As a result, with the weight of the foot, the accommodating member 3 made of an elastic net becomes thin, and when the foot approaches the plate-like electric heater 2, the pressure detected by the pressure sensor 10 increases, The temperature goes down. For this reason, it can be prevented that the foot is too close to the plate-like electric heating body 2 and the heating temperature of the foot rises to feel hot or cause low-temperature burns. Therefore, regardless of the weight of the foot or the weight applied to the housing member 3, it is possible to adjust the temperature to a comfortable temperature while keeping the feeling of putting the foot on and soft. Further, when the pressure detected by the pressure sensor 10 is equal to or larger than a predetermined magnitude, the temperature control unit 11 turns off the power source of the plate-like electric heating element 2. Thereby, it is possible to further prevent low-temperature burns and breakdowns.
