Are sandwiched between them. 43a is a heater wire and 43b is a heater substrate.

Also, the reflector 10 and the head casing 2
A space is formed between the head casing and the back surface of the reflection plate 10, and a temperature overheating prevention means C including a thermostat 5 and a temperature fuse 25 is attached to the back side of the reflection plate 10 to adjust the temperature of the heater 4. The temperature inside 2 is prevented from rising excessively.

Further, the grill 20 has a temperature indicating portion E.
Is attached so that it can be visually indicated that the temperature inside the head casing 2 has reached the optimum temperature for use, or that the temperature has become too high, thereby further improving usability and safety. The overheat prevention means C and the temperature marking means E will be described in detail later.

In the infrared therapeutic device A having the above structure, the gist of the present invention is that a plurality of engaging claws 15 are formed on the periphery of the infrared emitting plate 12 or the back plate 41 and the engaging claws 15 are folded. It is characterized in that it is bent and engaged with the back plate 41 or the infrared radiation plate 12.

In this embodiment, three engaging claws 15 are formed on the peripheral edge of the infrared radiation plate 12 having a circular shape, and the engaging claws 15 are engaged with the back plate 41 also having a circular shape. The infrared radiation plate 12 is attached to the back plate 41.

That is, as shown in FIG. 5, three engaging claws are provided on the peripheral edge of the infrared radiation plate 12 at regular intervals.
15, the engaging claws 15 are bent and engaged with the back side of the back plate 41 so as to be attached, and the heater body 43 and the mica plate are provided between the infrared radiation plate 12 and the back plate 41. Holds 42,42.

At this time, the front and back plates
Since both 12 and 41 are circular, they may relatively rotate and deviate. Therefore, a rotation restricting means is provided to prevent the infrared radiation plate 12 and the back plate 41 from relatively rotating.

As the rotation restricting means, the back plate 41
In the configuration in which the engaging claws 15 formed on the peripheral edge of the infrared radiation plate 12 are locked to the convex body 45 protruding on the back surface of the back plate 41, in the present embodiment, the convex body 45 is the screw body 41a of the back plate 41.
Is also used in.

That is, as shown in FIGS. 5 and 6 (a), an engaging recess 15a is formed in one of the engaging claws 15, and the engaging recess 15a is engaged with the screw body 41a. The relative rotation between the infrared radiation plate 12 and the back plate 41 is prevented.

Further, as a modification, as shown in FIG. 6 (b), at least two of the engaging claws 15 are formed to have a length up to the position of the screw body 41a, and can be rotated clockwise or counterclockwise. The engaging claws 15 and 15 may be locked to the screw bodies 41a and 41a so that the rotation is restricted.

As described above, in this embodiment, since the screw body 41a, which is an existing component, is used as the convex body 45, the number of components does not increase, which is advantageous in cost.

As shown in FIGS. 7 (a) and 7 (b),
45 may be provided separately from the screw body 41a, and the engaging claw 15 may be engaged in the same manner as described above. This is also structurally simple and has no hindrance in implementation.

Although various forms other than the above can be considered as the rotation restricting means, for example, as shown in FIGS. 8 (a) and 8 (b), infrared rays are radiated to the engaging portion 46 formed on the back plate 41. The engaging claws 15 formed on the peripheral edge of the plate 12 may be engaged.

That is, in FIG. 8A, the back plate is
A projecting surface 47 projecting outward is formed on a part of the peripheral edge of 41,
An engaging portion 46 is formed on the protruding surface 47, which is a notch portion cut to the peripheral position of the back plate 41, and the engaging claw 15 is engaged with the engaging portion 46 to regulate the rotation.

In FIG. 8B, a part of the peripheral edge of the back plate 41 is directly cut out to form the engaging portion 46, while one of the engaging claws 15 is formed along the peripheral edge of the infrared radiation plate 12. Formed from a pair of claw pieces 15b, 15b that are open on both sides, and the claw pieces 15b, 15b
Is engaged with the engaging portion 46 and expanded and locked on the back surface of the back plate 41.

In this way, the engaging portion 46 for engaging the engaging claw 15
By providing the infrared radiation plate with a simple structure
The 12 and the back plate 41 can be reliably connected.

Further, as the rotation restricting means, in addition to the above-mentioned constitutions, the infrared radiation plate 12 and the back plate 41 are formed in irregular shapes as shown in FIGS. 9 (a), 9 (b) and 9 (c). You can FIG. 9A shows the infrared radiation plate 12
The back plate 41 has a rectangular shape, FIG. 9 (b) has both plates 12 and 41 having a triangular shape, and FIG. 9 (c) has both plates 12 and 41 have a cocoon shape. In both cases, the infrared radiation plate 12 and the back plate 41 do not rotate relative to each other and do not shift from each other.

Both plates 12 and 41 are repeatedly heated and cooled. Particularly, since the infrared radiation plate 12 is coated with ceramics, the repeated ends of heating and cooling make it easy to flip the ends. The number of the engaging claws 15 can be increased to the positions shown by the phantom lines to prevent turning up.

As described above, when the irregular shape is adopted, there are various shapes other than the above-mentioned rectangle, triangle, and cocoon shape, and it is possible to manufacture a product excellent in design with a beautiful design, and a special component structure. It is not necessary to control rotation.

Here, taking an example in which the infrared radiation plate 12 and the back plate 41 are formed in a cocoon shape (see FIG. 9).
(see (c)), another form of the heater 4 will be described.

In this embodiment, the heater 4 is composed of the mica plates 42, 4
The heater main body 43 sandwiched between the two is directly sandwiched between the infrared radiation plate 12 provided with the engaging claws 15 and the back plate 41. However, as shown in FIG.
A structure in which a heater body 43 sandwiched between mica plates 42, 42 is interposed between a front plate 40 and a back plate 41 having a formed thereon, and the infrared radiation plate 12 is further mounted so as to be positioned in front of the front plate 40. Can also be The twin heater type is used here,
The first heater 43c and the second heater 43d are arranged in parallel.

At this time, the form of the engaging claws 15 formed on the infrared radiating plate 12 is an inward tilting type in which the tips of the claws face downward as shown in FIGS. 11 and 12, and FIG. 13 and FIG.
As shown in FIG. 4, the tip of the claw is directed upward, and
As shown in Fig. 3, there are three possible lateral fall-types in which the tip of the nail opens laterally in a bifurcated manner.

That is, in the inward tilting type, the one shown in FIG. 11 is the engaging claw 15 which is continuously provided to the infrared radiation plate 12.
Is bent to the side of the pack plate 41, and the tip side thereof is bent to the back surface of the back plate 41 for connection.

Further, the one shown in FIG. 12 is one of the features of the present invention, and the engaging claw 15 is provided with a buffer portion 15c.

That is, the engaging claw 15 is formed to be longer than that shown in FIG. 11, and a substantially U-shaped folded portion is formed between the engaging claw 15 and the back plate 41 (FIG. 12 (b)).
), Then bend to the side of the pack plate 41, and
The tip side thereof is bent and attached to the back surface of the back plate 41, and the folded-back portion serves as a buffer portion 15c.

That is, for example, when the infrared radiating plate 12 and the back plate 41 are made of different materials, and the coefficients of thermal expansion are different, the expansion and contraction amounts of the two differ. Here, if it is firmly connected by the engagement claw 15, there is a possibility that a crack may occur in the ceramic coating portion of the infrared radiation plate 12 due to the difference in the amount of expansion and contraction thereof,
The buffer portion 15c can absorb the difference in the amount of expansion and contraction, and it is possible to prevent cracks from occurring in the ceramic coating portion.

Further, when an unexpected shock is applied from the outside, the shock absorbing portion 15c can absorb the shock and prevent the internal heater body 43 from being damaged.

The cushioning portion 15c can also be applied to the engaging claws 15 that are connected to the circular infrared radiation plate 12 described above.

Next, the outward tilt type shown in FIGS. 13 and 14 will be described. Here, in the back plate 41,
As one form of the engaging portion 46, a fitting hole 48 into which the engaging claw 15 is fitted.
The engaging claw 15 is fitted into the fitting hole 48 to be connected. In FIG. 13, the engaging claw 15 is once bent downward, and then the tip is fitted into the fitting hole 48. It is bent again and connected.

On the other hand, in the structure shown in FIG. 14, the engaging claws 15 are not formed so as to project from the infrared radiating plate 12, but the infrared radiating plate 12 is cut into left and right inward from its ends. , The engaging claw 15 is formed in a state of being continuously provided with the joint portion 12a formed between the ends of both cuts, and the tip of the engaging claw 15 is fitted into the fitting hole 48, and on the back side of the back plate 41. It is bent up and connected.

This outward falling type can be wound around the end edge of the pack plate 41 by the engaging claw 15 extending upward from the fitting hole 48 and can be surely connected.

Next, the sideways type shown in FIG. 15 will be described. Here, the engaging claw 15 is the infrared radiation plate.
A pair of claw pieces 15b, 15b that are double-opened along the edges of 12
Both of the claw pieces 15b, 15b are engaged with the left and right sides of an engaging recess 49 as an engaging portion 46 formed at the edge of the back plate 41.

In FIG. 15 (a), the engaging recess 49 is formed.
Is formed by cutting out at the edge of the back plate 41, and in FIG. 15 (b), the two ears 49a, 49a protruding outward from the edge of the back plate 41 are used for engagement. Recess
I have 49.

As described above, a plurality of engaging claws 15 are provided around the infrared radiation plate 12 or the back plate 41.
And the engaging claw 15 is bent and engaged with the back plate 41 or the infrared radiation plate 12, it is necessary to form a caulked portion over the entire circumference of the infrared radiation plate 12 as in the conventional case. Therefore, the infrared radiating plate 12 can be easily attached to the back plate 41, the assembling process of the infrared radiating means B can be efficiently performed, and the cost can be reduced.

Since the rotation restricting means is provided,
The infrared radiation plate 12 and the back plate 41 rotate relative to each other, and there is no risk that the ceramics having the far infrared radiation characteristics applied to the infrared radiation plate 12 are cracked or separated due to the impact of the rotation.

Here, the infrared radiation plate described above is used.
Twelve forms will be described.

As described above, the infrared radiating plate 12 is formed by coating ceramics on the front surface of a metal plate such as stainless steel or aluminum. In the embodiments described so far, the surface is flat. However, this may be formed in an uneven surface shape as shown in FIGS.

FIG. 16 shows an infrared radiation plate 12 having a corrugated surface, and FIG. 17 (a) shows a large number of circular convex portions 12b and concave portions 12c on the surface.
Are formed. Note that, as shown in FIG. 17 (b), the convex portion 12b and the concave portion 12c may have a rectangular shape.

As described above, if the surface of the infrared radiation plate 12 is formed in a concavo-convex shape, the surface area can be increased, and the radiation amount of far infrared rays per unit time can be increased, thereby enhancing the effect of hyperthermia treatment. be able to. In particular, the corrugated one can concentrate and radiate far infrared rays like a Fresnel lens, and since the strength increases, the applied infrared radiation ceramics may be cracked or peeled off by an external force or the like. There is nothing to do.

Further, as shown in FIG. 18, the infrared radiation plate 12 can be formed in a net shape.

In this case, a metal wire made of stainless steel, aluminum or the like carrying ceramics is knitted on a net, or a wire previously knitted on the net is made to carry ceramics.

With such a structure, the heater 4 is seen from the mesh.
Heat (near-infrared rays) is radiated directly to the affected area, which warms the surface of the affected area and is comfortable for the user. Furthermore, the affected area is effectively warmed from the net. Since the far infrared rays are radiated to the deep part of the affected area, the effect of hyperthermia treatment by the far infrared rays is enhanced.

Further, as shown in FIG. 19, it is possible to form a donut shape by opening the central portion of the infrared radiation plate 12.

In this case, the heat from the heater 4 is directly radiated from the central opening 12d of the infrared radiation plate 12 to the affected area, and far infrared rays are radiated in a ring shape from the peripheral edge thereof. Therefore, it is possible to obtain the same effect as in the case where the mesh is formed.

Here, other configurations of the infrared treatment device A according to this embodiment will be described.

First, the head casing 2 will be described. As shown in FIG. 2, the head casing 2 has a so-called super-circular shape in which the corners of a square are curved so that the four curved portions 22 are positioned vertically and horizontally. I have to.

The curved portion 22 is provided with a large number of ribs 24 so that a child or the like can insert a finger into the head casing 2 to prevent an accident such as a burn from occurring, and a rectifying effect as described below. I have.

That is, between the peripheral edge of the infrared emitting means B and the peripheral edge of the head casing 2 which are formed in a circular shape,
An air circulation gap D is formed.

Furthermore, on the back of the head casing 2,
The air holes 23 are concentrically formed in two rows (see FIG. 4), and the air is circulated in the head casing 2 by the air holes 23 and the air circulation gap D to improve the cooling effect in the head casing 2. I am raising.

At this time, due to the rectifying effect of the ribs 24, the inflowing air is regulated in the passages by the ribs 24 and flows out in a dispersed state, so that heat is not locally concentrated. There is no risk of resin burning near the top of the head casing 2 where heat easily accumulates.

Also, as shown in FIG.
A rib 23a for preventing finger insertion is provided over the entire circumference on the inner peripheral side edge of the row of 23 toward the heat source portion 1, and like the rib 24, a child or the like can thrust the finger through the air hole 23. Even if the same finger insertion prevention rib 23a does not interfere with the insertion of the finger to the back, an accident such as a burn can be prevented.

Further, dust that has entered through the air holes 23 will not be blocked by the upper surfaces of the finger insertion preventing ribs 23a and accumulated inside the head casing 2.

The infrared therapeutic device A according to the present embodiment enhances the cooling effect in the head casing 2 as described above, but further, the temperature excessive rise prevention means C is provided to ensure the overheating of the head casing 2. I am trying to prevent it.

Moreover, the temperature excessive rise preventing means C and the heat source section 1 are the same.
The heater 4 is connected by a heat conducting means which is a rod-shaped or plate-shaped connecting body so that the heat generated by the heater 4 can be directly conducted to the overheat prevention means C to prevent overheat. I am sure.

That is, as shown in FIG. 4, the overheat prevention means C comprises a thermostat 5 and a temperature fuse 25, and is attached in a state of being in close contact with the bulging surface 13 provided at the center of the reflecting plate 10. .

The thermostat 5 is attached at a position that is the shortest distance from any of the three screw bodies 41a protruding from the back plate 41, that is, at the center of the triangle connecting the attachment portions of the three screw bodies 41a. In addition, as shown in FIG. 21, the thermal fuse 25 is tightly covered and fixed to the bulging surface 13 by a connector 9 with a pressing portion which is fastened together with one of the screw bodies 41a. Reference numeral 91 is a pressing portion formed at the tip of the connector 9 with a pressing portion.

In this way, the screw body 41 of the back plate 41 is
The heater 4, the thermostat 5 and the temperature fuse 25 connected to the bulging surface 13 of the reflector 10 by a are the rod-shaped screw body 41a as a connecting body, and the bulging surface 13 of the plate-shaped reflecting plate 10 to the heat conducting means. The heat from the heater 4 is directly transmitted to the thermostat 5 and the thermal fuse 25 through the screw body 41a and the bulging surface 13. Moreover, the thermal fuse 25
Is covered with the connecting member 9 having a pressing portion, so that more efficient heat conduction is achieved.

The mounting of the thermal fuse 25 is shown in FIG.
In addition to the one shown in FIG. 22, a fuse mounting recess 13a may be formed in the bulging surface 13 as shown in FIG. 22 so that the thermal fuse 25 can be held securely. In this case, since the mounting posture of the thermal fuse 25 can be regulated by the fuse mounting recess 13a, the efficiency of the assembling work is improved.

Further, since the contact area is increased, the reliability of the operation of the thermal fuse 25 can be increased.

By the way, in this embodiment, the thermostat 5 and the thermal fuse 25 are mounted on the rear surface of the bulging surface 13 of the reflection plate 10, but as shown in FIG. May be attached to.

Further, it is conceivable that the above-mentioned connecting member 9 with a pressing portion is formed in a box shape with one side opening, and not only the thermal fuse 25 but also the thermostat 5 is housed therein.

In this case, since there is no influence of air convection, the thermostat 5 and the thermal fuse 25 can be operated only by the conduction heat from the heater 4, so that more accurate control is possible.

Regarding the temperature inside the head casing 2, in this embodiment, as described above, the temperature indicating portion E is attached to the front surface of the head casing 2 facing the affected area to be treated, that is, the front surface of the grill 20. I have set up.

In the temperature indicating portion E, as shown in FIG. 24, a temperature sensitive color changing element 51 is embedded in a metal plate 50, and a protective seal 52 is provided.
It is configured by covering in a sealed state with. This covered seal 52
Prevents the temperature-sensitive color changing element 51 from being oxidized and having a short life. As the temperature-sensitive color changing element 51, any one such as a seal-shaped element and a paint-shaped element may be used.

The back surface of the metal plate 50, that is,
The surface on the heater 4 side is colored in a blackish color that easily absorbs radiant heat. This is because the silver color peculiar to metal is likely to reflect heat and the like, but since it is a black system, the heat from the heater 4 can be reliably absorbed, and the operability of the temperature-sensitive color changing element 51 can be improved. Is.

With this structure, when the temperature inside the head casing 2 reaches or exceeds the predetermined temperature, as shown in FIG.
The temperature indicating portion E1 in which the temperature sensitive color changing element 51 is embedded changes color, and the user can recognize that it is dangerous if the head casing 2 is approached any further.

In this embodiment, the entire protective seal 52 is colored yellow, and the temperature indicating portion E1 is changed to orange when the temperature exceeds a predetermined temperature.

Therefore, normally, the whole is yellow, but when the temperature becomes high, only the temperature indicating portion E1 changes to orange, so that the change with the surrounding color becomes obvious and the user can easily identify it. ing. Note that the color is not limited to any color as long as it is a color change that can be easily identified by the user.

As another embodiment, as shown in FIG. 26, the temperature-sensitive color changing element 51 may be directly painted on the grill 20 so that the marking characters and symbols are exposed when the temperature becomes high. By doing so, the degree of recognition of the user can be further increased. The exclamation point symbol is shown in FIG. 26 (a), the six-star mark is shown in FIG. 26 (b), and the word “danger” is shown in FIG.

Although the temperature indicator E has been described here as a safety aspect for indicating that the temperature has become high, the temperature may be set so as to indicate that the temperature has reached the operating temperature. In this case, it is immediately known that it is suitable for hyperthermia, and it is convenient for the user.

Next, the stand main body 3 which supports the head casing 2 will be described. The stand main body 3 has a flexible connecting rod 8 as shown in FIGS. 1 to 3 and 20.
On the center line of the pedestal portion 30 which is formed in a circular shape and which is provided at the rear eccentric position, and the timer switch 32 and the energizing lamp 33 are provided on the surface of the pedestal portion 30. On the other hand, on the back surface of the pedestal portion 30, a safety switch 6 that stops the energization when the infrared therapeutic device A is lifted or tilted during energization is attached. 36 is a leg seat, and a non-slip material is stuck on the surface.

The safety switch 6 includes a support 31 and a pedestal 30.
It is attached in a state of being urged downward so that it is located on the extension line connecting the centers of the When it protrudes to, the circuit is opened and the energization is stopped.

As described above, since the pedestal portion 30 is circular and the support column 31 connecting the head casing 2 is erected at a position eccentric to the rear portion with respect to the pedestal portion 30, it is relatively rearward. Although it is easy to fall down, as described above, since the safety switch 6 is provided so as to be located on the extension line connecting the centers of the column 31 and the pedestal portion 30, the safety switch 6 does not matter if it falls to the rear left or right. Works well without bias.

In particular, in this embodiment, as shown in FIG. 27, since the safety switch 6 is provided at the center of the pedestal portion 30, not only the rear side but also the front side, the left and right sides, in any direction. The safety will be improved because it will be activated immediately even when tilted. In FIG. 27, 28 is a conducting wire, and the head casing 2
The side is connected through the inside of the flexible connecting rod 8 to form the circuit. Further, 34 is an electric plug.

As shown in FIG. 20, the flexible connecting rod 8 has a cover 82 formed in a bellows shape covering a connecting pipe 81 in which a middle portion of a pipe whose base end is connected to a pedestal portion 30 is formed in a flexible manner. It has been configured. With this configuration, it is possible to bend the head casing 2 freely and radiate far infrared rays in an arbitrary direction. Reference numeral 27 denotes a connector, and the head casing 2 is attached to the flexible connecting rod 8 via the connector 27.

In FIGS. 20 and 27, W is a weight and is arranged so as to be located on the extension line connecting the centers of the support column 31 and the pedestal portion 30 and in the vicinity of the front end in the pedestal portion 30. doing.

By disposing the weight W at the above-mentioned location,
The weight of the pedestal portion 30 is increased to maintain the stability of the infrared therapeutic device A as a whole, and even when the head casing 2 is used in a state in which the head casing 2 is tilted backward as described above, it is possible to maintain the balance and to use it. Safety is improved.

Further, in FIG. 27, reference numeral 7 designates a substrate disposed in the pedestal portion 30 and provided with a resistor 71 and a diode 72. Further, FIG. 28 shows a circuit diagram of the infrared therapeutic device A. In the figure, the portion surrounded by the alternate long and short dash line is accommodated in the head casing 2, and the other portions are disposed in the pedestal portion 30. .

EFFECT OF THE INVENTION An infrared radiating means is provided by sandwiching a heater body between a back plate attached to the inner wall of a head casing and an infrared radiating plate obtained by coating ceramics on a metal plate such as stainless steel or aluminum. In the infrared treatment device, a plurality of engaging claws are formed on the periphery of the infrared emitting plate or the back plate, and the engaging claws are bent to engage with the back plate or the infrared emitting plate. In addition, since it is not necessary to form a caulked portion around the entire circumference of the infrared radiation plate, the infrared radiation plate can be easily attached to the back plate, and the infrared radiation means can be assembled efficiently, and the cost can be reduced. You can

By forming the cushioning portion on the engaging claw, for example, the infrared radiation plate and the back plate are made of different materials, and the thermal expansion coefficient is different, and the engaging claw is stronger. Even if the expansion and contraction amounts are different when connected to each other, the difference in expansion and contraction amount can be absorbed by the buffer portion, and cracks can be prevented from occurring in the ceramic coating portion of the infrared radiation plate. .

Further, even when a shock from the outside is applied, the shock can be damped by the shock absorbing portion to prevent the heater body from being damaged.

Since the infrared radiation plate and the back plate are provided with the rotation restricting means for preventing the relative rotation of the infrared radiation plate and the back plate, the infrared radiation plate and the back plate are relatively rotated, and the impact of the rotation is generated. As a result, there is no risk of cracks or peeling occurring in the ceramics having the far-infrared radiation characteristics applied to the infrared radiation plate.

Since the above-mentioned rotation restricting means has the infrared radiation plate and the back plate of different shapes and can take various shapes other than the circular shape, a product having a beautiful design and excellent design is obtained. It can be manufactured and the rotation can be regulated without the need for a special component structure.

The rotation restricting means has a structure in which the engaging claws formed on the peripheral edge of the infrared radiating plate are engaged with the convex member projecting from the back surface of the back plate, whereby the rotation restricting can be performed with a simple structure. You can do it.

Since the convex body is also used as the screw body for attaching the back plate to the head casing, existing parts can be used, and the number of parts does not increase, which is advantageous in terms of cost.

The rotation restricting means has a structure in which the engaging claw formed on the peripheral edge of the infrared radiation plate is engaged with the notch formed in the back plate, so that the infrared radiation plate and the back plate can be simply structured. Secure connection is possible.
