Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot heating device incorporated in a lower end portion of a home kitchen or a wash basin. 2. Description of the Related Art When cooking or washing while standing in front of a system kitchen or wash basin at home, the feet cool down in winter, so a foot heater is provided at the lower end of the system kitchen or wash basin. It has been practiced to heat the feet by incorporating the footsteps. [0003] As a domestic heating device, a heating device using a heater lamp as a heat source has been widely put into practical use. For example, as disclosed in JP-A-8-82424, a heater arranged in a casing is disclosed. 2. Description of the Related Art A reflection radiation type heating device in which a lamp is surrounded by a reflector and infrared rays are radiated from an opening in a front surface of a casing is known. However, when such a reflection radiation type heating device is used as a foot heating device, when standing in front of the opening on the front surface of the casing from which infrared rays are radiated, the feet are well heated, but the heating device is separated from the opening on the front surface of the casing. There is a problem that the feet are hardly heated when standing in the upright position. For this reason, for example, Japanese Patent Application Laid-Open No. 9-243176
As disclosed in Japanese Unexamined Patent Publication, a blower-type heating device is used in which a blower is disposed behind a heater lamp so that infrared rays are radiated from an opening in the front of the casing and warm air is also blown out. There are many. In the case of the ventilation type foot heating device, there is an advantage that even if the user stands at a position slightly deviated from the opening on the front surface of the casing, the foot is heated by the warm air which spreads right and left from the opening. [0005] By the way, since drainage and gas pipes and the like are arranged inside the system kitchen and the wash basin, the casing of the foot heating device is attached to the system kitchen and the wash basin. When incorporated in the lower end, these pipes interfere with the casing, and the casing can be incorporated only in a limited narrow range. Therefore,
The width of the front of the casing is limited. [0006] Further, in the ventilation type foot heating device, an air suction port is provided in the casing, but it is necessary to cover the suction port with a filter so that dust does not flow into the casing from the suction port. And if you use a foot heater,
Dust accumulates on the filter and must be removed from the suction port and cleaned periodically. For this reason,
A suction port was provided on the front surface of the casing so that the filter could be easily removed from the suction port. Therefore, as described above, the width of the opening on the front surface of the casing from which infrared rays are radiated and from which warm air is sent out is limited by the width of the front surface of the casing and restricted by the air suction port, and cannot be large. For this reason, there was a problem in that the heating range in front of the system kitchen or the wash basin was narrow. [0007] In view of the above, the present invention makes it possible to increase the width of the opening at the front of the casing from which infrared rays are radiated and from which warm air is sent out, and to effectively heat the feet over a wide area in front of a system kitchen or the like. It is another object of the present invention to provide a foot heating device in which a filter that covers the air suction port can be easily removed. In order to achieve this object, the present invention provides a heater lamp, a reflector surrounding the heater lamp, and a blower disposed inside a casing, which are formed on a front surface of the casing. From the opening that was emitted, while emitting infrared rays, in the foot heating device where hot air is sent out, a suction port for air is formed on a surface other than the front surface where the opening of the casing is provided, and a filter that covers the suction port, Attached to a slide member that can slide in the front direction of the casing. Embodiments of the present invention will be specifically described below with reference to the drawings. As shown in FIG. 1, a casing 1 of a foot heating device is incorporated, for example, at the lower end of a system kitchen, and when standing in front of the system kitchen, the feet are heated. The casing 1 is
It is a flat box having a size of, for example, 460 × 240 × 76 mm, and has a horizontally long opening 11 formed on the front surface thereof. A suction port 12 is formed on an upper surface of a rear portion of the casing 1, and a blower 4 including a cross flow fan is disposed below the suction port 12. The suction port 12 is covered with the filter 5. The casing 1 has a power consumption of, for example, 8
A heater lamp 2 composed of a 0 W tubular halogen incandescent lamp and a gutter-shaped reflecting mirror 3 surrounding the heater lamp 2 are arranged. Infrared rays radiated from the heater lamp 2 are directly or reflected by the reflecting mirror 3 and a casing is provided. Irradiation is performed from one opening 11. A high-radiation material, for example, a ceramic-based coating agent (not shown) mainly composed of alumina and silica is applied to the back surface of the reflector 3, and when the heater lamp 2 is turned on, the temperature of the reflector 3 becomes high. Emits a lot of infrared light from The reflecting mirror 3 has an intake hole 31 and an exhaust hole 3.
The cooling air blown from the blower 4 enters the reflecting mirror 3 through the intake hole 31, cools the inner surfaces of the heater lamp 2 and the reflecting mirror 3, becomes hot air, and is discharged from the exhaust hole 32. You. The cooling air that cools the back surface of the reflecting mirror 3 also becomes warm air, is discharged from the opening 11 together with the warm air discharged from the exhaust holes 32, and is provided for heating together with infrared rays emitted from the opening 11. The front surface of the reflecting mirror 3 is covered with a glass plate 33 so that water or the like does not splash on the heater lamp 2. Heat shielding plates 13 are arranged above and below the reflecting mirror 3 to prevent the casing 1 from becoming hot, and cooling air passing through the back surface of the reflecting mirror 3 approaches the reflecting mirror 3, and In addition to the fact that a high radiation material is applied to the back surface of the device, warm air is efficiently generated. Here, as shown in FIG. 2, two heater lamps 2 are disposed in the same plane in a C-shape with the reflecting surfaces of the two reflecting mirrors 3 facing each other at an angle. ing. That is, the imaginary lines L, L of the tube axis of the heater lamp 2 are arranged at an angle of, for example, 90 °. Therefore, the infrared rays radiated from the heater lamp 2
Irradiation spreads right and left not in the direction orthogonal to the direction but in the oblique direction. A power switch 14 and an abnormality indicator light 15 are mounted on the front surface of the casing 1, and a thermal fuse 16 is arranged near the opening 11. If the thermal fuse 16 blows due to overheating, the energization of the heater lamp 2 is automatically stopped, and the abnormality indicator lamp 15 is lit to notify the abnormality. As shown in FIG. 3, a pair of guide rails 17 extending from the front to the rear are provided on the upper surface of the casing 1, and the thin plate-shaped slide member 6 is slidably disposed along the guide rails 17. Have been. The slide member 6 has an L-shaped bent portion 61 formed at the front thereof, and the filter 5 is attached to the rear of the slide member 6. And the grip part 61 usually has the opening 1
1, the filter 5 is provided with a suction port 12 formed on the upper surface of the rear part of the casing 1 as described above.
Is covered. When the slide member 6 and the filter 5 are made flexible and freely bent at the upper and rear corners of the casing 1, the air suction port 1
2 can also be provided on the back of the casing 1. In any case, since the suction port 12 is not formed in the front surface of the casing 1, the opening 11 that emits infrared rays and blows out warm air can be formed almost completely on the front surface of the casing 1. The width of the opening 11 can be increased. Therefore, the feet can be effectively heated over a wide area in front of the system kitchen or the like. When the power switch 14 is turned on, the heater lamp 2 is turned on and the blower 4 operates. Therefore, the warm air is sent out from the wide opening 11 of the casing 1 by the blower 4 and spreads right and left, and the heater lamp 2 emits infrared rays because the virtual lines L of the tube axis intersect at an angle. The heating effect of the hot air spreading right and left is also synergistically influenced by the heating effect of the infrared rays spreading wide and diagonally from the opening 11 and the right and left, and the effective heating effect can be obtained over a wide range. . Therefore, even if the user stands at a position distant from the opening 11, the feet are efficiently heated. If such a foot heater is used for a long period of time, dust accumulates on the filter 5 and the filter performance deteriorates. Therefore, the state shown in FIG.
4B, the slide member 6 is slid forward as shown in FIG. 4B, and as shown in FIG. 4C, when the slide member 6 is pulled out of the casing 1, the filter 5 can be easily taken out. Can be. Then, the filter 5 is cleaned, and the slide member 6 is inserted into the guide rail 17 again and slid rearward to the state shown in FIG. In this way, the filter 5 can be easily removed and cleaned even though the suction port 12 is provided on a surface other than the front surface of the casing 1. As described above, according to the present invention, the heater lamp, the reflecting mirror surrounding the heater lamp, and the blower are arranged inside the casing, and the opening is formed on the front surface of the casing. Emits infrared light,
In the underfoot heating device through which the hot air is sent, the air suction port is formed on a surface other than the front surface where the opening of the casing is provided, so that the infrared radiation is emitted and the width of the opening through which the hot air is sent is wide. It is possible to effectively heat the feet over a wide area such as a system kitchen. Since the filter covering the air suction port is attached to the slide member slidable in the front direction of the casing, the filter can be easily removed and cleaned.
