DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0015]
As shown in FIGS. 1 to 3, the infrared treatment device A is formed in an opening at one end, and a head casing 2 in which the heat source 1 is accommodated and disposed so as to radiate infrared rays or far infrared rays toward the opening side. And a stand body 3 that holds the head casing 2.
[0016]
The head casing 2 is formed so as to have a bowl shape when viewed from the front, and the heat source portion 1 disposed therein is also substantially similar to the head casing 2. 20 is a grill detachably attached to the opening side of the head casing 2, and in FIG. 3, 23 is a plurality of air holes formed in the rear peripheral wall of the head casing 2, which are formed in two rows and into the head casing 2. Air is circulated to prevent overheating in the head casing 2 in use.
[0017]
As shown in FIG. 4, the heat source unit 1 has a bowl-shaped reflecting plate 10 attached to a boss 21 projecting from the inner surface of the head casing 2, and a heat insulating material 11 that is also shaped like a bowl on the reflecting plate 10. Thus, a plate-like heater portion 4 having an infrared plate 12 provided on the front surface is attached, and a space is formed between the reflecting plate 10 and the back surface of the head casing 2. In FIG. 4, 10a is a reflector mounting screw, 10b is the same color, and the stand body 3 has a support 31 for supporting and connecting the head casing 2 to the pedestal 30 as shown in FIGS. A power supply on / off timer switch 32, an energizing lamp 33 composed of LEDs, and a heater changeover switch 34 are provided on the surface of the pedestal 30.
[0018]
With the above configuration, when the timer switch 32 is operated and set at a desired time, the infrared plate 12 is heated by the heater unit 4 and far infrared rays are emitted, and the reflector 10 efficiently irradiates the front.
[0019]
Irradiated far-infrared rays can be warmed up to the back of the affected area at the same time, which can surely promote metabolic action and loosen up litter.
[0020]
In the above-described configuration, the present invention is such that the heat source section 1 has a plurality of heaters 4a and 4b arranged in parallel with each other, and the heaters 4a and 4b are sandwiched between a pair of thin plate-like heat conductors. It is characterized by being integrally formed.
[0021]
Further, heat conduction loss prevention that prevents heat generated in each heater 4a, 4b from being mutually conducted to a part of the heat conductor located between the plurality of heaters 4a, 4b as much as possible. It is also characterized by the provision of means.
[0022]
As described above, the heat source unit 1 is obtained by attaching the plate-like heater unit 4 to the reflecting plate 10 via the heat insulating plate 11, and is configured as follows in the present embodiment.
[0023]
That is, as shown in FIG. 5, the heater section 4 has a diameter smaller than that of the reflector 10 and is provided as a thin plate-like heat conductor on a bowl-shaped back plate 41 provided with a mounting screw 41a for the reflector 10. A thin plate-shaped heater substrate 43 sandwiched between a pair of mica plates 42, 42 formed into a shape and coated with an infrared generating material such as ceramics through a front plate 45 having the same shape as the back plate 41 and fired. Are integrally formed by sandwiching them by the infrared plate 12. The periphery of the infrared plate 12 is caulked and attached to the back plate 41. 41b is a collar for mounting the back plate 41.
[0024]
Heater wires 43a and 43b are wound around the heater substrate 43 in a state where they are separated from each other on the left and right sides to form separate left and right heaters 4a and 4b. Then, only one or both of the heaters 4a and 4b can be used simultaneously by the heater changeover switch 34 provided on the pedestal 30 of the stand body 3.
[0025]
Further, thermostats 5 and 5 are attached to the back surface of the reflector 10 for the left and right heaters 4a and 4b, respectively, so that the temperature of both heaters 4a and 4b is adjusted.
[0026]
In the present embodiment, as described above, the central portions of the back plate 41, the mica plates 42 and 42, the front plate 45, and the infrared plate 12 are appropriately cut out to form a constricted portion 12a to form a bowl shape. This constitutes a heat conduction loss prevention means. Therefore, heat conduction loss can be efficiently prevented with a simple configuration.
[0027]
Thus, since the heat conduction loss preventing means is intended to make the heat conduction area as small as possible, the notch (constriction 12a) for that purpose has a shape as shown in FIG. You can also.
[0028]
Further, the heat conduction loss preventing means may be an opening 12b as shown in FIGS. 7 (a) and 7 (b) in addition to the notch (constricted portion 12a). In FIG. 7A, a perforated opening 12b is provided so as to be positioned between the left and right heaters 4a and 4b.
[0029]
In FIG. 7B, a slit-like opening 12b is provided so as to be positioned between the left and right heaters 4a, 4b, and a heat insulating material 12c is further provided in the opening 12b. This prevents heat transfer due to radiant heat and convection heat. The heat insulating material 12c can be disposed in the perforated opening 12b.
[0030]
In the present embodiment, the heater unit 4 is composed of left and right heaters 4a and 4b. However, the number of heaters is not limited to two. For example, three or four heaters may be appropriately set. In this case, as shown in FIGS. 8 (a) and 8 (b), the constricted portion 12a and the opening portion 12b can be combined to form a heat conduction loss preventing means.
[0031]
In this embodiment, as shown in FIG. 9 (a), the front plate 45 and the infrared plate 12 are separated, but as shown in FIG. 9 (b), the front plate 45 is directly attached to the front surface of the front plate 45. Ceramics may be applied and fired. Further, as shown in FIG. 9 (c), the infrared plate 12 may be formed only of ceramics. In this case, the infrared plate 12 may be connected by caulking the periphery of the back plate 41.
[0032]
In this way, by arranging the heat source part 1 side by side with the left and right heaters 4a and 4b separated from each other, if both the left and right are heated at the same time, the radiation range of infrared rays and far infrared rays is expanded, and efficient thermal treatment is performed. In addition, if the area of the affected area is small, spot radiation can be achieved by using only one heater 4a, so that efficient thermal treatment can be performed.
[0033]
In addition, the heaters 4a and 4b are integrally formed by sandwiching the heaters 4a and 4b with a pair of thin plate-like heat conductors, so that the number of assembling steps can be reduced and the cost can be reduced compared to the case where the heater unit 4 is divided into a plurality of separate members. In addition to being advantageous, it is excellent in design and can improve aesthetics.
[0034]
In addition, by providing the constricted portion 12a as a heat conduction loss prevention means, when only one is used, the generated heat is prevented from being conducted to the other side as much as possible, and the portion immediately before the heater to be used Since the infrared plate 12 is efficiently heated, it does not take a long time to reach a predetermined temperature at which far infrared rays are emitted.
[0035]
Here, the other structure of this infrared rays therapeutic device A is explained in full detail.
[0036]
As shown in FIGS. 10 and 11, the infrared treatment device A according to the present invention is located at the center of the back surface of the pedestal 30 of the stand body 3 when the infrared treatment device A is lifted or tilted during energization. A safety switch 6 for stopping energization is attached.
[0037]
The switch 6 is mounted in a state of being biased downward, and closes the circuit when pushed into the pedestal 30. However, when the switch 6 projects downward from the pedestal 30 by the biasing force, the circuit is opened. The power supply is stopped.
[0038]
As described above, since the safety switch 6 is provided at the center of the pedestal portion 30, the safety switch 6 is immediately operated regardless of the inclination in any direction, and the safety is improved. 10 and 11, reference numeral 28 denotes a conductive wire, which is connected to the head casing 2 side through the inside of the flexible coupling rod 8 to form the above circuit.

FIG. 12 shows a circuit diagram of the present infrared treatment 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 others are disposed in the pedestal portion 30. 25 and 25 are thermal fuses.
[0043]
Next, the connecting rod for connecting and supporting the head casing 2 to the stand body 3 will be described. The connecting rod of the infrared treatment device A is a flexible connecting rod 8 as shown in FIGS. 1 to 4 and FIG. Yes. Therefore, as shown in FIG. 2, the head casing 2 can be freely bent and far infrared rays can be emitted in an arbitrary direction. FIG. 2 shows a state in which the head casing 2 is bent in the left-right direction, but the head casing 2 can be bent in a range of 360 ° including the front-rear direction.
[0044]
Further, when the head casing 2 is arbitrarily positioned as described above, the weight of the head casing 2 is lost, and there is a risk of falling.

[0046]
By arranging the weight body W at the above-mentioned location, the weight of the pedestal portion 30 is increased to maintain the stability of the entire infrared treatment device A, and for example, the balance is maintained even when the head casing 2 is tilted backward. Can be maintained and safety in use is improved.
[0047]
As shown in FIG. 10, the flexible connecting rod 8 is configured by covering a pipe 81 formed flexibly with a middle part of a pipe whose base end is connected to a pedestal 30 with a cover 82 formed in a bellows shape. The central portion of the head casing 2 is attached to the upper end of the flexible connecting rod 8 via a connector 27.
[0048]
The connector 27 has a rotary hinge structure as shown in FIG. 14, and includes a ring 27c for giving a click feeling when the head casing 2 is rotated.
[0049]
In FIG. 14, 2d is a mounting bolt, 27a is formed so that its front end can be freely fitted in a sliding groove 2e provided in the center of the rear surface of the head casing 2, and a connector 27 provided with a connecting surface 27d for connecting to the flexible pipe 81 at its rear end. The inner case 27b is an outer case that can be fitted into the inner case 27a, 28a is a lead-out hole, and 81a is a fixing nut that is screwed into a male thread formed at the upper end of the flexible pipe 81.
[0050]
With the above configuration, as shown in FIG. 15, the head casing 2 can be rotated 90 ° clockwise and the heaters 4a and 4b can be used in a vertically arranged state.
[0051]
At that time, since the head casing 2 is connected to the connector 27 at the center thereof, the balance during rotation is good.
[0052]
In addition, the infrared treatment device A according to the present embodiment can be used by appropriately switching the left, right, and front modes by the heater changeover switch 34. Is configured such that the head casing 2 can be rotated by 90 ° clockwise as viewed from the front via the connector 27, and the right heater 4b is energized if the heater changeover switch 34 is set to the right mode in this rotated state. To generate heat.
[0053]
In other words, the infrared treatment device A allows only the heater located on the upper side of the heaters 4a and 4b arranged side by side when the head casing 2 is rotated by 90 ° (see FIG. 4).
[0054]
In addition, the infrared treatment device A according to the present invention can also be provided with a grip 35 on the column 31 of the stand portion 3 as shown in FIG. The grip 35 here is made of rubber with anti-slip processing and is provided on the upper portion of the support 31. Thereby, the movement by carrying the infrared treatment device A becomes easy.
[0055]
Here, the case where the infrared treatment device A according to the present invention is actually used will be described below.
[0056]
FIG. 17 shows, for example, the case where the acupuncture points along the back and the spine are treated with heat, and the longitudinal direction of the head casing 2 is positioned along the spine and the left and right heaters 4a and 4b are used at the same time. As a result, the entire back can be warmed at the same time, and an efficient treatment can be performed.
[0057]
FIG. 18 shows a case where, for example, a knee treatment is performed, the head casing 2 is positioned so that the longitudinal direction thereof is vertical, and only the upper heater 4b is used.
[0058]
As described above, when the head casing 2 is used in the vertical direction, only the upper side of the heater unit 4 can be operated. Therefore, as shown by arrows f and g in FIG. As a result, heat can be prevented from staying in the head casing 2. That is, the heat rises as it warms up, but in this case, since the heater 4b is previously positioned above the head casing 2, the heated air immediately escapes out of the casing, and the inside of the head casing 2 It can prevent overheating.
[0059]
In addition, since the upper heater 4b is operated, when the head casing 2 is moved in the front-rear direction by the flexible connecting rod 8 rather than operating the lower side, the vertical range of far-infrared radiation is expanded and the usability is improved. .
[0060]
Another embodiment will be described with reference to FIGS. 19 (a) and 19 (b).
[0061]
This is because the dust intrusion prevention device 15 is provided in the head casing 2 and the grill 20 and the air hole 23 provided in the head casing 2 can be freely opened and closed. FIG. 19 (a) shows the opened state in FIG. (b) shows the closed state.
[0062]
That is, the grill 20 is composed of a large number of movable louvers 20a, and an opening / closing member 2a having an alignment hole 23a that can be aligned with the air hole 23 is disposed along the inner wall surface of the head casing 2, and a knob 2b The air hole 23 can be freely opened and closed by the above operation. Here, an interlocking mechanism 2c having a pair of meshing gears is provided to interlock the operation of the knob 2b and the opening / closing operation of the louver 20a.
[0063]
With such a configuration, it is possible to prevent dust and the like from entering the head casing as much as possible, and it is easy to clean the inside, and it is possible to take a long time until cleaning. In order to attach the opening / closing member 2a, the outer shape of the head casing 2 is formed in a half-cylindrical shape, and the above-described finger insertion preventing rib 23a is eliminated.
