Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a transpiration mat impregnated with a transpiration agent that can be evaporated by heating.

(Prior art) A pine base material impregnated with a transpiration agent such as an insecticide that can be evaporated by heating is placed on a heater in the main body of the device, and the heater heats the pine base material to evaporate the transpiration agent. This type of transpiration device is widely known.

However, in the above-mentioned transpiration devices, heat transfer occurs at the contact area with the heater based on the weight of the pine base material, so the heating efficiency tends to decrease due to poor contact, and it takes time to obtain the desired transpiration. There are some difficulties.

In view of the above-mentioned problems, it has recently been proposed to embed a heater in the pine tree itself (Special Public Interest Publication No. 57-
Publication No. 8698).

The transpiration mat disclosed in the publication includes a pine base material, a heater plate with a conductive wire portion deposited on its surface and embedded in the pine base material with the side opposite to the conductive wire portion exposed, and a conductive wire portion. It consists of a pair of heater terminals protruding from both ends of the unit, and is used by connecting the heater terminals to a power supply terminal provided on the stand.

(Problems to be Solved by the Invention) However, in the transpiration mat disclosed in the above publication, it is necessary to separately attach the heater terminals to the heater plate, so there is a drawback that the attachment work is time-consuming and the manufacturing cost increases. Furthermore, since one side of the heater plate is exposed to the outside from the mat base material, thermal energy is likely to be wasted due to heat dissipation from the exposed side, resulting in an increase in power consumption.

The present invention has been made in view of the above circumstances, and its purpose is to provide a transpiration mat that can be manufactured easily and inexpensively and that can evaporate with high efficiency.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a heater layer made of a resistive material is printed in a meandering pattern on the surface of a substrate having a predetermined shape, and both ends of the heater layer are aligned with the substrate. While extending to the side to form a heater plate,
A pine base material impregnated with a transpiration agent is brought into close contact with both sides of the heater plate, so that both ends of the heater layer are exposed as terminals for power supply.

(Function) The transpiration pine according to the present invention can be manufactured by preparing a heater plate and a pine base material respectively, and simply laminating these parts.

Further, since both ends of the heater layer are exposed as terminal portions with the mat base material in close contact with both surfaces of the heater plate, no separate parts are required to form the terminal portions.

Furthermore, since the mat base materials are closely attached to both sides of the heater plate, the heat generated in the heater layer when power is supplied can be transferred to the mat base materials on both sides without waste.

(Embodiment) Figs. 1 and 2 show an embodiment of the present invention, in which Fig. 1 is a perspective view of a transpiration mat, and Fig. 2 is an exploded perspective view of the transpiration mat.

The transpiration mat 1 shown in FIG. 1 is composed of a heater plate 2 and a pair of mat base materials 3, and has a laminated structure.

The heater plate 2 has a rectangular printed circuit board 2a.
A heater layer 2b made of a resistive material is pattern-printed in a meandering pattern on the surface of the heater layer 2b, and both ends of the heater layer 2b are extended to one side of the printed circuit board 2a. In the illustrated example, one side portion of the printed circuit board 2a is bent downward, and the bent portion of the heater layer 2b is used as a terminal portion 2c for power supply.

The mat base material 3 is made of a liquid-containing material such as woven fabric, non-woven fabric, cardboard, resin foam, porous ceramic, etc., and has a rectangular shape with the same width and short length as the heater plate 2. Further, the pine base material 3 is impregnated with a transpiration agent such as a deodorant or an insecticide that can be evaporated by heating. This mat base material 3 is superimposed on both sides of the heater plate 2 and fixed with a heat-resistant adhesive.

Here, a method for manufacturing the above-mentioned transpiration mat 1 will be explained with reference to FIG. In manufacturing, the heater plate 2 on which the heater layer 2b is formed and the pine base material 3 impregnated with the transpiration agent are prepared respectively, and first, one side on the terminal side of each of both sides of the heater plate 2 is removed. With the pine base materials 3 aligned on three sides, both pine base materials 3
is glued to the heater plate 2. Next, the pine base material 3
By bending one side of the heater plate 2 exposed downward at a substantially right angle, the transpiration mat 1 shown in FIG. 1 is manufactured.

According to the above-described embodiment, the heater plate 2
By preparing a mat base material 3 and a mat base material 3, the transpiration mat 1 can be easily manufactured by simply laminating these parts, and since the number of parts is small and the cost is low, the mat itself can be manufactured at low cost.

In addition, with the mat base material 3 in close contact with both sides of the heater plate 2, both ends of the heater layer 2b are connected to the terminal portions 2c.
Since the terminal part is exposed as a terminal part, no separate parts are required to form the terminal part, and the number of parts can be reduced and the manufacturing process can be simplified.

Furthermore, since the mat base material 3 is closely attached to both sides of the heater plate 2, the heat generated in the heater layer 2b when power is supplied can be transferred to the mat base material 3 on both sides without waste, reducing power consumption. transpiration with high efficiency.

In the above embodiment, one side of the heater plate is bent downward, but bending is not necessarily necessary as long as both ends of the heater layer are exposed.

FIG. 3 shows a socket for supplying power to the transpiration mat 1 described above.

The socket 10 shown in the figure has an insertion opening 11 into which the end of the transpiration mat 1 can be inserted, and a pair of electrodes 12 provided on the inner bottom surface of the insertion opening 11. A power cord 13 is pulled out from.

When using the above-described transpiration mat 1, connect the power cord 13 of the socket 10 to an applicable power source, and insert the transpiration mat 1 into the insertion opening 11 of the socket 10.
by inserting the terminal side of each terminal 2c into the electrode 12.
All you have to do is contact it. As a result, transpiration pine 1
Electric power is supplied to the heater layer 2b of the heater layer 2b.
The pine base material 3 on both sides is heated by the heat generated in b, and the transpiration agent evaporates.

Also, FIG. 4 shows a different socket from that shown in FIG.

The socket 20 shown in the figure has an insertion port 21 into which the end of the transpiration mat 1 can be inserted, a pair of electrodes 22 provided on the inner bottom surface of the insertion port 11, and can be plugged into a household power outlet. power plug 23
The power plug 23 is connected to each electrode 22 via a lead wire 24.

When using the above-mentioned transpiration mat 1, insert the power plug 23 of the socket 20 into a power outlet, insert the terminal side of the transpiration mat 1 into the insertion opening 21 of the socket 20, and connect each terminal part 2c. It may be brought into contact with the electrode 22. The transpiration effect is similar to that of the socket 10 described above.

(Effects of the invention) As detailed above, according to the invention, if a heater plate and a pine base material are prepared respectively, a transpiration pine can be easily manufactured by simply laminating these parts. Since the number of parts is small and the cost is low, the mat itself can be manufactured at low cost.

In addition, since both ends of the heater layer are exposed as terminals with the mat base material in close contact with both sides of the heater plate, no separate parts are required to form the terminals, and the number of parts can be reduced. can simplify manufacturing man-hours.
