Abstract

PURPOSE:To prevent snow from getting clogged to the inside of a tire housing, by attaching a panel heater, to be opposed to the back of a tire, to an inner surface of the tire housing. CONSTITUTION:A panel-form heater H is attached to the inside of each tire housing 2 of front wheels 1 of an automobile. In this case, the heater H is installed as to be opposed to the back of each front wheel 1 at both sides. This heater H consists of a flexible panel in which a faced electric heating element 6 is embedded, and a cord 3 is led out of this heating element 6. This cord 3 is connected to a power source via an on-off switch SW and a cigar socket 4. Accordingly, at the time of driving in a snow-covered district, if the on-off switch SW is made in circuit and the heater 6 is heated, the snow rolled in space between each front wheel and the housing 2 is melted by heat, thus snow is in no case clogged in the tire housing 2.

Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION (Industrial Field of Application) The present invention relates to an apparatus for melting snow and ice that adheres to the inside of a tire housing of an automobile when the automobile travels in a snowy area.

(Conventional technology and its problems) When a car walks in a snowy or snowy area, snow gets caught inside the tire housing by the wheels and freezes, impeding driving. is not easy to remove. Conventionally, the only way to remove snow that has gotten into the tire housing is to poke it with a stick or the like.

The present invention provides an automobile tire housing snow melting device that prevents snow from clogging the inside of the tire housing.
(The purpose is to

[Structure of the invention]

(Means for Solving the Problems) In order to achieve this object, in the present invention, a panel-shaped heater is attached to the inner surface of a tire housing of an automobile so as to face behind the tire.

(Function) By installing the panel heater in this way,
Snow caught between the wheel and the inner surface of the tire housing is melted by the heat and falls, so that the inside of the tire housing is not clogged with snow.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, a panel-shaped heater H, which is a feature of the present invention, is installed inside a tire housing 2 of, for example, a front wheel 1 of an automobile. It is preferable that the lower end of the heater H hangs slightly below the vehicle body so as to function as a mudguard. The plate heater H is an electric heater, and is connected via a cord 3 to an on-off switch SW that connects it to a power source (battery). Note that this switch SW can also be connected to the cigarette lighter socket 4. As shown in FIG. 2, panel heaters H are arranged oppositely behind the wheels 1.1 on both sides. The panel heater H attached to the inner surface of the tire housing 2 has an arc shape as shown in FIG.

As shown in FIG. 3, the panel heater H consists of a flexible panel 4 with a planar electric heating element 6 embedded therein, the lower end of which is folded back toward the back side. A cord 3 is derived from the planar heating element.

Planar heating element 6 embedded inside panel heater H
As shown in FIG. 4, it consists of a large number of strip-shaped heating elements arranged in parallel, and both ends of these strip-shaped heating elements 6 are connected by a common current-carrying part 7.7. The re-energizing part 7.7 is connected to the electrode 8
．． 8, and cords 3a and 3b are connected to these electrodes and put together as the cord 3. Furthermore, a pair of mounting holes 9.9 are provided in the upper part.

The panel heater H has a cross-sectional configuration as shown in FIG. An insulating resin layer 11 such as an olefin elastomer is provided on the front side (the side facing the wheel 1) of the sheet heating element 6.
However, a fluororesin layer 12 is laminated on the front side thereof. This resin layer 12 is made of, for example, Teflon (trade name), and serves as a snow accretion prevention layer to which snow and the like do not easily adhere. Further, a heat insulating layer 13 made of foamed urethane resin or the like is provided on the back side of the planar heating element 6, and a resin layer 14 such as an olefin elastomer is provided on the back side. These planar heating elements 6, resin layer 11, snow accretion prevention layer 1] layer 12,
The thickness of the heat insulating layer 13 and the resin layer 14 is, for example, 0.
25 m+*, 1 dragon, 0.1+ am, 5 dragon, 1 m+s, and the total thickness of the heater H can be approximately 81111 mm. Further, it is preferable that the heating element 6 has a voltage of 12 volts and 55 watts.

The panel heater H can be attached to the tire housing through its attachment hole 9 by screwing bolts or the like.

When driving in snowy or snowy areas, the switch SW is turned on to cause the electric heating element 6 to generate heat. As a result, the snow caught inside the tire housing 2 will melt, or even if it snows, it will be only a small amount. According to the test results, when the outside temperature was relatively high (about 0° C.) and the snow quality contained a lot of moisture, the snow fell naturally. In addition, when the outside temperature is low and the snow quality is low in moisture, there is little chance of the snow falling naturally, but it was relatively easy to remove it when the vehicle stopped or parked.

On the other hand, when a heater is not installed, the snow accumulated inside the tire housing becomes quite hard and difficult to remove.

The anti-snow layer of the panel heater H effectively prevents snow from accumulating on the surface of the heater, and the heat insulating layer 13 prevents heat transfer from the tire housing to the vehicle body.

Furthermore, since the heater H hangs down like a mudguard, it functions only as a mudguard when it is not generating heat.

〔Effect of the invention〕

As described above, in the present invention, the panel-shaped heater can melt the snow that tends to adhere to the inside of the tire housing, and prevent the snow that has accumulated inside the tire housing from solidifying and becoming an obstacle to driving.
