Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deodorizing device that provides an appropriate deodorizing effect to a room.

Deodorants conventionally used in automobile air conditioners and the like generally have the property that the amount of emission increases as the ambient temperature increases, and conversely, the amount of emission decreases as the ambient temperature decreases. In addition, the temperature inside a car cabin fluctuates dramatically between summer and winter, or between daytime and nighttime, so the amount of deodorant released during the daytime in summer is excessive, and the amount released is insufficient during low temperatures in winter, which is an inconvenience. occurs.

Therefore, in conventional deodorizing devices, in order to adjust the amount of deodorizing agent emitted, the user manually closes the emission hole when the ambient temperature is high and opens the emission hole when the ambient temperature is low. That was an annoyance.

SUMMARY OF THE INVENTION Therefore, the present invention provides a deodorizing device that eliminates the trouble of manually opening and closing a diffusion hole each time the user adjusts the amount of deodorizing agent released, and that always provides an appropriate amount of deodorizing agent. With the goal.

That is, the deodorizing device of the present invention has a heating element placed near the deodorant in a storage box in which the deodorant is housed, and a heating element that is connected to the heating element through an electric current, and a heating element that is connected to the heating element intermittently and provided in the storage box. It is characterized in that it is provided with a temperature switch having a temperature-sensitive metal piece that switches open and close the emission hole.

An embodiment in which the present invention is applied to an automobile air conditioner shown in the drawings will be described below. FIG. 1 is a front sectional view showing this embodiment, and FIG. 2 is a top view thereof.

The storage box 1 is made of resin and is divided into an upper storage box Q and a lower storage box 1b. The upper storage box 1a is provided with several mounting claw ICs for latching, and the lower storage box 1b is provided with a convex portion 1d at a portion corresponding to the mounting claw IC for latching. The upper storage box 1a and the lower storage box 1b are connected by the attachment claw IC and the convex portion 1d engaging with each other using the elasticity of the resin.

A net 3 for placing the deodorant 2 is removably installed on the upper part of the lower storage box. placed on this net 3,
The deodorant 2 is, for example, limonene (Co.

Felt is impregnated with vegetable oils and fats, including HI3), and stored in a breathable polyethylene bag. At the bottom of the net 3, a nichrome wire 4 serving as a heating element and having a power consumption of about 2 W is attached to the lower storage box 1b with screws 5 via terminals 6 and 7. The terminal 6 is connected to the temperature switch 9 by a fixed part lead wire 8 of the temperature switch 9, which will be described later, to the temperature switch 9b. It is fixed to the side wall of the storage box 1b.

On the other hand, a diffusion hole 9 is provided in the earthen wall of the upper storage box 1a, penetrating the inside and outside of the storage box 1, and a temperature switch 10 is located below the diffusion hole 9. The temperature switch 10 includes a movable part 10a having a bimetal structure as an example of a temperature-sensitive metal piece, a fixed part 10b made of copper, and a movable part 10a and a fixed part 10b.
The movable part 10a is attached to the side wall of the upper storage box 1a by hot-filming a resin adhesive bezel 11, and the movable part 10a is attached to the side wall of the upper storage box 1a.
It is connected to a terminal 12 provided at b by a lead wire 13. As described above, the lead wire 13 is fixed to the lower storage box 1b by the hooking claw piece 1e. This terminal I2 and the terminal 7 are connected to the same power source through a connection plug (not shown) or the like. On the other hand, the temperature switch fixing part Job is attached to the side wall of the upper storage box 1a facing the temperature switch movable part 10a by hot-filming a resin rivet 14.

Further, the upper wall of the upper storage box 1a is formed in such a shape that the diffusion hole 9 can be closed when the movable part 10a of the temperature switch 10 reaches a certain set temperature or higher, as shown in FIG. 3a.

That is, the inner surface 9a of the storage box where the divergence hole 9 is provided.
is sloping.

When this embodiment is used in an automobile, the installation location is not particularly limited, but it is installed, for example, at the bottom of the instrument panel or in the area between the rear seat and the rear window. In addition, the method for attaching the deodorizing device to the car body is that it can be attached to a resin hook part and attached to a part of the car body inside the car using a well-known Velcro tape that can be attached and removed. Attach to. In addition to the mounting method described above, it is also possible to mount by screwing or the like.

As a power source for the deodorizing device of this embodiment, a 12 V direct current power source for an automobile (not shown) is connected to the terminal 7 of the deodorizing device through a power switch installed on an instrument panel (not shown).
．． I am trying to connect to 11. In this case, the TIi source switch is provided separately in the deodorizing device, but it may be provided in the deodorizing device main body.

Next, the operation of this embodiment will be explained.

When the ambient temperature is low, for example, the temperature inside storage box 1 is 10℃
At this time, the movable part 10a of the temperature switch 10 closes the contact 10C as shown in FIG.
is in the energized state, and the temperature inside the storage box 1 rises to - with the energization time. In accordance with this temperature 11, the emitted 11jF It of the deodorizer 2 increases and evaporates from the diffusion hole 9 into the vehicle interior (not shown).

Furthermore, the temperature inside storage box 1 increases, for example, to 25'c.
When the amount exceeds the required amount, the amount of deodorizing agent 2 emitted also increases to the required amount. At this time, the movable part 10a of the temperature switch 10 bends toward the wall of the upper storage box 1a as shown in FIG. The temperature inside the storage box 1a will no longer rise.

Next, when the temperature inside the storage box 1 decreases to below 25° C., the movable portion 10a of the temperature switch 10 changes to state C (not shown in FIG. 3), and contacts IOC.

closes again.

In this manner, the temperature switch 10 automatically opens and closes in response to temperature changes, and the nichrome wire 4 is energized intermittently.

In addition, when the surrounding temperature becomes extremely high such as when parking under the scorching sun, for example when the temperature inside the storage box 1 reaches 80℃, the bimetallic temperature switch can be moved as shown in Figure 3a. The portion 10a closes the emission hole 9, and can prevent an excessive amount of the deodorant 2 from being emitted into the vehicle interior.

The embodiment described above is applied to an automobile air conditioner, but it can also be applied to general household indoor use by changing the power supply voltage of the deodorizing device and using a nichrome wire 4 with an appropriate power consumption. It is also possible to do so.

Note that the deodorant in the present invention is defined to include a fragrance that emits a fragrance and eliminates a bad odor.

In addition, in this example, nichrome wire 4 was used as the heating element, but
It goes without saying that other materials may be used as long as they generate heat when electrical current is passed through them (for example, a PTC heater), and instead of the bimetal used as a temperature-sensitive metal piece, a material that changes shape in response to temperature changes may be used. It goes without saying that other materials may also be used.

As described above, according to the present invention, the temperature switch 10 automatically opens and closes in response to temperature changes inside the storage box 1 to intermittently energize the heating element, and in addition to this, the deodorizer 2 is released. Hole 9
Since it can be opened and closed, it has the effect of automatically supplying an appropriate amount of deodorant 2 to be released in response to changes in ambient temperature.
