(First embodiment)
The heating device included in the disclosed disclosure includes, for example, a vehicle device mounted on an interior member in a vehicle interior, a device mounted on an interior member in a room other than the vehicle interior, and a heater main body that supplies radiant heat. It is a device. This heating device is a device that has a heat generating portion and supplies radiant heat to the outside by heat released from the heat generating portion. Therefore, this heating device is a radiant heater device capable of providing radiant heat transmitted by a heat ray from a high-temperature solid surface to a low-temperature solid surface regardless of the presence of air or the like therebetween.

1st Embodiment demonstrates the example which provides the radiation heater apparatus 1 provided in a vehicle interior as an indoor heating apparatus. The radiation heater device 1 can be installed in a room of a moving body such as a road traveling vehicle, a ship, and an aircraft, a room of a building fixed to land, a device having a heating function, and the like. A radiation heater device 1 according to the first embodiment will be described with reference to FIGS.

In FIG. 1, the radiation heater device 1 constitutes one of the heating devices for the passenger compartment. In each embodiment shown below, the case where the radiation heater apparatus 1 is provided in a vehicle interior is demonstrated as an example of the heating apparatus for vehicles. The radiation heater device 1 is an electric heater that generates heat by being fed from a power source such as a battery or a generator mounted on a moving body. The radiation heater device 1 has a plate-shaped heater body. The radiation heater device 1 generates heat when electric power is supplied. The radiant heater device 1 radiates radiant heat R mainly in a direction perpendicular to the surface in order to warm an object positioned in a direction perpendicular to the surface.

In the passenger compartment, there is a seat 20 for the passenger 21 to sit on. Hereinafter, the radiation heater device 1 may be simply referred to as the device 1. The device 1 is installed indoors so as to radiate radiant heat R to the feet of the passenger 21. The device 1 is installed on a wall surface in the room. The indoor wall surface is an interior member such as an instrument panel, a door trim, or a ceiling, and constitutes an interior member of the vehicle. The apparatus 1 is installed so as to face an occupant 21 in a normal posture assumed. For example, a road traveling vehicle has a steering column 22 for supporting the handle 23. Therefore, the apparatus 1 can be installed on the lower surface of the steering column 22, an instrument panel, a door trim, a ceiling, and the like, which are examples of interior members, so as to face the occupant 21.

The cross-sectional view of FIG. 2 shows an example of the configuration of a typical heater body related to the apparatus 1. The apparatus 1 is formed in a substantially rectangular thin plate shape. The apparatus 1 includes a substrate unit 10 as an example of a heater body. The substrate unit 10 includes a plurality of heat generating units 11 and a pair of terminals 12 that are conductive units. The apparatus 1 can also be called a planar heater that radiates radiant heat R mainly in a direction perpendicular to the surface. The substrate unit 10 constitutes a heater body including a heat generating unit 11 that generates heat when energized.

The substrate unit 10 is made of a resin material that provides excellent electrical insulation and withstands high temperatures. The substrate unit 10 is, for example, a multilayer substrate. The substrate unit 10 includes a front surface layer 101, a back surface layer 102, and an intermediate layer 103. The surface layer 101 faces the radiation direction of the radiant heat R and is located on the front surface side (first surface side) of the heater body. The surface layer 101 is a surface that is disposed to face a part of the body of the occupant 21 that is the heating target in the installation state of the device 1. The back surface layer 102 forms the back surface of the heater body and is located on the back surface side (second surface side) of the heater body. The intermediate layer 103 supports the heat generating portion 11 and the terminal 12 while being sandwiched between the front surface layer 101 and the back surface layer 102. The substrate unit 10 is a member for supporting a plurality of heat generating units 11 each having a linear shape. The front surface layer 101, the back surface layer 102, and the intermediate layer 103 are insulating portions made of a material having a lower thermal conductivity than the heat generating portion 11 and the terminal 12. For example, the front surface layer 101, the back surface layer 102, and the intermediate layer 103 are made of polyimide resin.

Each of the plurality of heat generating portions 11 is made of a material that generates heat when energized. The heat generating part 11 can be made of a metal material. For example, the heat generating portion 11 can be made of copper, silver, tin, stainless steel, nickel, nichrome, or the like. The plurality of heat generating portions 11 each have a linear shape or a plate shape parallel to the surface of the substrate portion 10, and are arranged in a distributed manner with respect to the surface of the substrate portion 10. Moreover, the heat generating part 11 is a single linear body, and may be arranged so as to be distributed over the entire substrate part 10.

Each heat generating portion 11 is connected to a pair of terminals 12 arranged at a predetermined interval. The heat generating part 11 is disposed with a gap between the pair of terminals 12. The plurality of heat generating portions 11 are connected in parallel to the pair of terminals 12 so as to bridge between the pair of terminals 12, and are provided over substantially the entire surface of the substrate portion 10. The plurality of heat generating portions 11 are provided so as to be sandwiched between the front surface layer 101 and the back surface layer 102 together with the intermediate layer 103. The plurality of heat generating portions 11 are protected from the outside by the substrate portion 10. The front surface layer 101 and the back surface layer 102 can be provided by printing or adhesion.

Each heating part 11 is a member that is thermally connected to at least the surface layer 101 and generates heat when energized. Thereby, the heat generated by the heat generating portion 11 is transmitted to the surface layer 101. The heat generated by one heat generating portion 11 is radiated from the surface layer 101 to the outside as radiant heat via a member such as the substrate portion 10 and is provided to the opposing occupant 21.

The heat generating unit 11 is set to have a predetermined length in order to obtain a predetermined heat generation amount. Therefore, each heat generating portion 11 is set to have a predetermined resistance value. In addition, each heat generating part 11 is set in size and shape so that the thermal resistance in the lateral direction becomes a predetermined value. Accordingly, the plurality of heat generating units 11 generate a predetermined amount of heat when a predetermined voltage is applied. The plurality of heat generating portions 11 generate a predetermined amount of heat and rise to a predetermined temperature. The plurality of heat generating portions 11 that have risen to a predetermined temperature heat the surface layer 101 to a predetermined radiation temperature. And the apparatus 1 can radiate the radiant heat R which makes the passenger | crew 21, ie, a person, feel warmth.

The output, temperature, and heat generation amount of the heat generating unit 11 are controlled by the heater ECU. The heater ECU can control the output, temperature, amount of heat generation, and the like of the heat generating unit 11 by controlling the voltage value and the current value applied to the heat generating unit 11. For example, the heater ECU can supply power obtained from a battery to the device 1 and control the supplied power. The heater ECU can control the output of the heat generating unit 11 by the power control.

Therefore, the heater ECU varies the amount of radiant heat given to the passenger 21. When energization of the device 1 is started by the heater ECU, the surface temperature of the device 1 rapidly rises to a predetermined radiation temperature to be controlled. For this reason, warmth can be given to the passenger | crew 21 rapidly also in winter.

When an object comes into contact with the surface layer 101 of the apparatus 1, the heat transferred from the heat generating portion 11 to the surface layer 101 is rapidly transferred to the contacting object. As a result, the temperature of the contacting portion of the surface layer 101 is rapidly reduced. Therefore, the surface temperature of the device 1 in the part in contact with the object is rapidly lowered. The heat of the part in contact with the object is transmitted to the object in contact and diffuses to the object in contact. For this reason, an excessive increase in the surface temperature of the contacting object is suppressed.

Next, the detailed configuration of the radiation heater device 1 will be described with reference to FIGS. FIG. 4 shows the configuration of the radiation heater device 1 and the relationship between the radiation heater device 1 and the interior member. FIG. 5 shows the configuration of the guard member 3, the heater body, and the base member 4 and their relationship. The steering column 22 is provided with an opening 220 having an opening area in which the device 1 can be mounted. The device 1 is provided so as to be located on the back side of the opening 220, that is, on the back side of the steering column 22, in other words, in a space opposite to the vehicle interior with respect to the interior member. The board | substrate part 10 comprises a heater main body.

The radiation heater device 1 includes a guard member 3 located on the vehicle interior side, and a base member 4 located on the back side of the interior member and combined with the guard member 3. The base plate part 10 is supported by the guard member 3 at a part of the front surface, which is an end surface on the indoor side, and the base member 4 is supported at a part of the back surface by the guard member 3 and the base member 4 from both sides. It is pinched.

The guard member 3 and the base member 4 constitute a heater case that houses the heater body. The heater main body is provided in the heater case so that the indoor side surface thereof is located on the back side (the side opposite to the indoor side) of the interior member relative to the indoor side surface of the interior member. The Z direction from the back side of the interior member toward the vehicle interior is a direction in which the base member 4, the heater body, and the guard member 3 are arranged in this order. Therefore, the guard member 3 is a front case member (first surface case member) that supports the heater body from the front side, and the base member 4 is a back case member (second case) that supports the heater body from the back side. Surface side case member).

The guard member 3 is a frame-like member that includes a lattice portion 31 and a frame portion 32 erected from the periphery of the lattice portion 31. The frame portion 32 forms a square shape having four side portions. The lattice portion 31 forms a large number of hole portions 30. The guard member 3 has an opening formed on the vehicle interior side that is a set of a large number of holes 30 that is equal to or larger than the size of the surface layer 101. The lattice portion 31 is preferably provided substantially flush with the surface of the steering column 22. With this configuration, since the lattice portion 31 does not protrude from the interior member, the appearance is good and the collision between the lattice portion 31 and the occupant can be suppressed.

The frame portion 32 of the guard member 3 protrudes from the vehicle interior side where the lattice portion 31 is formed toward the back side of the interior member, that is, the opposite side of the vehicle interior so as to form a quadrilateral wall.

The frame portion 32 of the guard member 3 is provided with a plurality of attachment pieces 34 protruding outward. Each attachment piece 34 is formed with a through hole. When the guard member 3 and the base member 4 are assembled together, the fixing screw 441 is inserted into the through hole. A plurality of boss portions 44 in which screw holes are formed are provided on the outer peripheral edge portion 41 of the base member 4. Each boss portion 44 is provided so that the screw hole of the boss portion 44 and the through hole of each attachment piece 34 coincide with each other when the guard member 3 is set and fixed to the base member 4 at a predetermined position. ing. By tightening the screw 441 through the screw hole of the matched boss portion 44 and the through hole of the attachment piece 34, the attachment piece 34 is pressed against the end face of the boss portion 44 by the head of the screw 441, and the guard member 3 is It is fixed to the base member 4.

Further, the base member 4 and the guard member 3 may be configured so as to form an integral heater device in a state where the heater body is sandwiched by providing a portion that fits together.

The base member 4 is a frame-like member that includes a base portion 40 and an outer peripheral edge portion 41 that forms a frame portion standing from the periphery of the base portion 40. The outer peripheral edge portion 41 forms a square shape having four side portions, and has the same shape as the frame portion 32 of the guard member 3. When the outer peripheral edge portion 41 is fitted into the frame portion 32 of the guard member 3, the guard member 3 and the base member 4 are assembled together. Therefore, the base part 40 is installed so as to face the back surface layer 102 of the heater body.

The base member 4 constitutes a part of the heater case by being combined with the guard member 3 integrally. The base member 4 includes a plurality of protrusions 43 that protrude from the surface of the base portion 40 that faces the back surface layer 102 of the heater body. The plurality of protrusions 43 protrude toward the back surface of the substrate portion 10 that is the back surface of the heater body.

The plurality of protrusions 43 are provided so as to have a protruding dimension that does not come into contact with the back surface of the heat generating part 110 that is an area where the heat generating part 11 is provided. That is, the plurality of projecting portions 43 do not contact the substrate portion 10 in a normal state in which the substrate portion 10 is supported by the guard member 3 and the base member 4 and integrally assembled. Therefore, a space portion is generated between the substrate portion 10 and the base portion 40 of the base member 4. This space portion constitutes an air chamber in which air exists. This air chamber is formed as a space portion surrounded by the frame portion 32 of the base member 4 and the guard member 3 and the heater body. The air chamber is a space portion that is partitioned and formed on the back side of the heater body, and serves as a heat insulating portion that suppresses the heat of the heater body from being radiated to the back side.

The plurality of protrusions 43 are evenly arranged without deviation in the entire base portion 40 facing the back surface of the heater body. The protruding portion 43 protrudes from the base portion 40 in a pin shape. The protrusion 43 constitutes a columnar part such as a cylinder or a prism. The plurality of protrusions 43 are arranged at equal intervals in the longitudinal direction X along the long side of the rectangular heater body, and at equal intervals in the short direction Y along the short side of the heater body. .

The interval between the protrusions 43 arranged on the base 40 is preferably set to be smaller than the outer diameter of a finger or an object that is assumed to be able to apply an external force to the heater body, for example, in a range of 5 mm to 10 mm. Can be set. This is because, when an external force acts on the heater body, local dents in the heater body are suppressed to reduce the degree of damage.

Also, it has been confirmed by experiments that the interval between the protrusion 43 and the back surface of the heater body is preferably set to 1 mm or more. Moreover, it has been confirmed by experiments that the distance between the base portion 40 of the base member 4 and the back surface of the heater body is preferably set to about 5 mm or more, or about 10 mm or more.

The frame portion 32 of the guard member 3 is provided with a plurality of front-side support pieces for supporting a part of the surface layer 101 that is the end surface on the indoor side of the substrate portion 10. For example, the support piece on the front side protrudes from the predetermined position of the frame portion 32 inwardly along the substrate portion 10. The base part 40 of the guard member 3 is provided with a plurality of back side support pieces for supporting a part of the back layer 102 of the substrate part 10. The support piece on the back side protrudes in a direction intersecting the substrate part 10 from a predetermined position of the base part 40 toward the indoor side, for example.

As described above, the substrate portion 10 is sandwiched from both sides by the plurality of support pieces of the guard member 3 and the plurality of support pieces of the base member 4 and is fixed at a part of the outer peripheral edge. These support pieces partially support the non-heat generating portion 112 located on the outer peripheral edge of the heater body where the heat generating portion 11 is not provided.

Thus, a part of the outer peripheral edge of the heater main body, which is also the non-heat generating portion 112, is fixed by the heater case including the guard member 3 and the base member 4. The substrate part 10 is supported by a heater case at a part of the outer periphery that is the non-heat generating part 112, and is installed in a state where the back surface of the heat generating part 110 does not contact the plurality of protrusions 43. Further, the non-heat generating portion 112 may be provided over the entire outer peripheral edge of the heater body.

The apparatus 1 supports the substrate unit 10 by sandwiching the substrate unit 10 from the front side and the back side by a heater case including the guard member 3 and the base member 4. An elastic member 5 that is elastically deformed is provided at a portion that sandwiches the substrate portion 10. The elastic member 5 constitutes an elastic part that is elastically deformed by a clamping force acting in a direction perpendicular to the surface perpendicular to the surface of the substrate part 10. The elastic member 5 is a separate component from the heater case and the heater body, and is formed of a rubber-like elastic elastomer. The elastic member 5 is a cylindrical body. For example, the elastic member 5 is a cylindrical body.

The substrate part 10 includes a non-heat generating part 111 where the heat generating part 11 is not provided in a part corresponding to a place where the elastic member is provided. This non-heating part 111 contacts the elastic member 5 on one side. A through hole 1111 is formed in the non-heating portion 111. Around the through hole 1111, it is provided so as to surround the non-heat generating portion 111.

The non-heat generating portion 111 has a surface area larger than the area in contact with the elastic member 5 on the surface facing the elastic member 5. That is, the non-heat generating portion 111 is in contact with the end surface of the cylindrical elastic member 5 at a part of one surface.

The base member 4 includes a columnar portion 48 for positioning the substrate portion 10 and the elastic member 5. The columnar portion 48 has a pin shape protruding from the base portion 40 of the base member 4 toward the guard member 3 or the indoor side. The columnar part 48 does not limit the outer shape, and may be, for example, a prism, a cylinder, or a tapered shape.

The columnar portion 48 is inserted into the through hole 1111 of the non-heat generating portion 111 and the inner peripheral surface of the elastic member 5 in a state where the substrate portion 10 is sandwiched from the front side and the back side by the heater case. In other words, the columnar portion 48 extends through the non-heat generating portion 111 and the elastic member 5 in a state where the substrate portion 10 is sandwiched by the heater case. That is, the columnar part 48, the through hole 1111 and the elastic member 5 are in a coaxial positional relationship.

The columnar part 48 is provided so as to leave a gap between the inner peripheral edge of the through hole 1111 and the outer peripheral surface of the columnar part 48. This gap is preferably set to such a dimension that the inner peripheral edge of the through hole 1111 and the columnar part 48 do not come into contact with each other when the substrate part 10 extends due to heat generation.

The elastic member 5 is provided so as to be sandwiched between the base portion 40 of the base member 4 and the substrate portion 10. In the elastic member 5, one end surface of the cylindrical body is in contact with the base portion 40, and the other end surface of the cylindrical body is in contact with the non-heat generating portion 111. Therefore, the compressive force received from the base part 40 and the non-heating part 111 acts on the elastic member 5 in the axial direction of the cylindrical body (same as the Z direction in the figure). Since the holding force received in the direction perpendicular to the surface (same as the Z direction in the drawing) is relieved by the elastic force of the elastic member 5, the substrate portion 10 is held in a state where the surface pressure acting on the non-heat generating portion 111 can be reduced. . In other words, the elastic member 5 can serve as a cushion that relieves the clamping force received by the heater body from the heater case. Therefore, by holding the substrate portion 10 using the elastic member 5, the substrate portion 10 can be held in a state where the expansion and contraction accompanying the heat generation of the substrate portion 10 is allowed.

Among the front side case member and the back side case member, the guard member 3 that is the other case member includes a receiving portion 35 that supports the columnar portion 48. The receiving portion 35 is a cylindrical body having one end protruding toward the heater body open and the other end closed. The receiving portion 35 receives the columnar portion 48 from the opening at the tip. The receiving portion 35 supports the columnar portion 48 so as to surround the outer peripheral surface of the columnar portion 48 until the tip of the columnar portion 48 comes close to the closed other end wall 351.

The inner peripheral surface of the receiving portion 35 may come into contact with the outer peripheral surface of the columnar portion 48, or a positional relationship in which the columnar portion 48 is movable inside the receiving portion 35 by providing a slight gap therebetween. It is good. Therefore, the receiving portion 35 supports the columnar portion 48 so that the columnar portion 48 cannot be largely displaced inside the receiving portion 35 and the relative positional relationship between the two is maintained.

Further, FIG. 7 shows a configuration in which the heater body is supported by the heater case. As shown in FIG. 7, when the elastic member 5 is hardly elastically deformed, the tip of the columnar portion 48 is in a positional relationship where it does not contact the other end wall 351. With this configuration, when the clamping force increases and the elastic deformation amount of the elastic member 5 increases, the elastic member 5 can be elastically deformed until the tip of the columnar portion 48 contacts the other end wall 351. Therefore, the apparatus 1 can tolerate elastic deformation of the elastic member 5 over a wide range. Furthermore, it is preferable that the gap between the tip of the columnar part 48 and the other end wall 351 is set to a dimension that prevents the two from contacting when the elastic member 5 is elastically deformed to the maximum extent. According to this, the board | substrate part 10 can be supported in the state which can move to the direction parallel to the surface, without the part clamped of the board | substrate part 10 being completely fixed.

It is preferable that there are a plurality of portions where the substrate portion 10 is sandwiched by the front case member and the back case member via the elastic member 5. For example, in the example shown in FIGS. 5 and 6, the substrate portion 10 is sandwiched via the elastic member 5 at two locations.

The outer peripheral edge 41 of the base member 4 is provided with a plurality of mounting pieces 45 protruding outward. Each attachment piece 45 is formed with a through hole. A fixing screw is inserted into the through hole when the radiation heater device 1 is fixed to the interior member. A plurality of boss portions 221 having screw holes are provided on the back side of the steering column 22 (see FIG. 3). Each boss portion 221 is provided so that the screw hole of the boss portion 221 and the through hole of each attachment piece 45 coincide when the apparatus 1 is set and fixed to the interior member at a predetermined position. . By tightening the screw through the screw hole of the matching boss portion 221 and the through hole of the attachment piece 45, the attachment piece 45 is pressed against the end face of the boss portion 221 by the head of the screw, and the device 1 becomes an interior member. Fixed.

The substrate unit 10 includes a fixing unit 1120 for fixing the substrate unit 10 to the base member 4 by screwing or the like. The fixing portion 1120 is a plate-like portion provided at the end of the substrate portion 10 and has a plurality of through holes 1121 through which fixing screws 471 are inserted. The base member 4 is provided with a plurality of boss portions 47 in which screw holes are formed. Each boss portion 47 is provided so that the screw hole of the boss portion 47 and each through hole 1121 coincide with each other when the substrate portion 10 is set and fixed to the base member 4 at a predetermined position.

The base member 4 is provided with a female connector 46. The female connector portion 46 includes a power input terminal 461 protruding from the substrate portion 10 side. The other end portion 4611 of the terminal 461 is installed in the fixed portion 1120 and is electrically connected to the heat generating portion 11 from there through a conductive pattern or the like. For example, the other end portion 4611 of the terminal 461 is securely installed in a state of penetrating the fixing portion 1120.

The female connector portion 46 is connected to a male connector portion including a power output terminal to which power is supplied from the outside. When the male connector portion is connected to the female connector portion 46, the power output terminal and the power input terminal 461 are connected, and an external power source is input to the heat generating portion 11 of the board portion 10. Will be in a state.

The base member 4 is located on the back side of the heater body, and also functions as a heat insulating part that suppresses the heat of the heater body being radiated to the back side. The base member 4 is made of a heat-insulating material such as a foamable material, a urethane resin, or a rubber material. The base member 4 is made of a material having higher heat insulation performance than the heat generating portion 11 and the surface layer 101.

Next, the procedure for mounting the radiation heater device 1 on the interior member will be described. First, the heater body is held between the guard member 3 and the base member 4 at a predetermined position with the elastic member 5 interposed therebetween. In this state, the guard member 3 and the base member 4 are held by the screws 441 described above. Tighten and fix with. Further, when the guard member 3 is mounted on the steering column 22, the mounting pieces 45 and the boss portions 221 are aligned, and these are fastened and fixed by the screws described above. Thereby, the radiation heater device 1 is fixed to the interior member. Moreover, you may comprise so that the case where the base member 4 and the guard member 3 were united may be fixed to an interior member by providing the part fitted with an interior member.

Next, the effect which the heating device of a 1st embodiment brings is explained. A radiant heater device 1 that is a heating device includes a sheet-like heater body (for example, the board portion 10) that emits radiant heat by heat supplied from a heat generating portion 11, and a heater that is mounted on an interior member in a vehicle compartment and accommodates the heater body. A case. The heater case includes a guard member 3 and a base member 4 that sandwich the heater body and are assembled together. The heater case supports the heater body by sandwiching it from the front side and the back side. An elastic portion (for example, an elastic member 5) that is elastically deformed by a clamping force acting in a direction perpendicular to the surface perpendicular to the surface of the heater body is provided at a portion that sandwiches the heater body.

According to this configuration, since the elastic portion is provided at the portion where the heater body is sandwiched, the heater body is supported in a state in which the sandwiched portion is movable in a direction parallel to the surface without being fixed by the elastic force. Is done. That is, the heater main body is held with an appropriate force adjustment by the elastic force acting in the direction perpendicular to the surface, and can be held so as to extend and contract in any direction parallel to the surface of the heater main body. In the heater body supported by the heater case in such a sandwiched state, even if the heater body expands and contracts due to heat, the sandwiched portion allows expansion and contraction, so that expansion and contraction is not prevented at the sandwiched portion. Therefore, the heating apparatus which can avoid that the stress concentration by wrinkles and sagging arises in the said clamping part in a heater main body is obtained. Furthermore, since an elastic force acts on the part that sandwiches the heater body, it can contribute to suppressing vibration of the heater body and resonance with other members.

In addition, the heater body includes a non-heat generating portion 112 where the heat generating portion 11 is not provided. A part of the outer peripheral edge of the heater body, which is also the non-heat generating portion 112, is fixed by the heater case. According to this configuration, the heater body is fixed at a part of the outer peripheral edge. The heater body can be expanded and contracted in any direction parallel to the surface except for the fixed portion.

Further, the heater body includes a non-heat generating portion 111 at a portion corresponding to a place where the elastic member 5 (an example of an elastic portion) is provided. According to this structure, since the part of the heater main body which the elastic member 5 contacts is the non-heating part 111, it can suppress that the heat of a heater main body is transmitted to a heater case.

Further, the heater case includes a columnar portion 48 that extends through the non-heat generating portion 111 and the elastic portion and positions the heater main body and the elastic portion. According to this configuration, it is possible to accurately set the position where the heater body is held in a state where an elastic force is applied. Furthermore, when the elastic member 5 is a separate part from the heater case, the elastic member 5 can be installed at an accurate position, and the elastic force of the elastic member 5 can be accurately applied to the heater body.

Further, one base member 4 of the front side case member and the rear side case member includes a columnar portion 48 protruding toward the other. The guard member 3 that is the other case member includes a receiving portion 35 that supports the columnar portion 48. According to this configuration, since the columnar portion 48 is supported by the receiving portion 35, the deformation of the columnar portion 48 can be suppressed while the heater case sandwiches the heater body.

Further, a plurality of portions where the elastic member 5 is provided and the heater main body is sandwiched are provided. According to this structure, it becomes possible to hold | maintain a heater main body in the state which made the elastic force act in several places. For this reason, a heater main body can be stably hold | maintained in the state which can be expanded-contracted.

Also, the heater body is provided so that the outer peripheral edge is at least a portion fixed by the heater case, and a gap is formed with the heater case in a direction parallel to the surface of the heater body. The gap is set to a dimension that prevents the heater body and the heater case from contacting when the heater body is extended by heat generation. According to this configuration, even if the heater body expands and contracts due to heat, it can be prevented from coming into contact with the heater case, and the heater body is unlikely to sag. Moreover, it can suppress that the heat of a heater main body is transmitted to a heater case.

Further, a through hole 1111 through which the columnar portion 48 passes is formed in the non-heat generating portion 111. The columnar part 48 is provided so as to leave a gap between the inner peripheral edge of the through hole 1111 and the outer peripheral surface of the columnar part 48. The gap is set to a dimension that prevents the inner peripheral edge of the through hole 1111 from contacting the columnar portion 48 when the heater body is extended by heat generation. According to this configuration, even if the heater main body expands and contracts due to heat, the non-heat generating portion 111 can be prevented from coming into contact with the columnar portion 48 and the heater main body is less likely to sag.

Further, the non-heat generating portion 111 of the sandwiched heater body has a surface area larger than the area in contact with the elastic member 5 on the surface located on the elastic member 5 side. According to this configuration, it is possible to suppress heat from being transmitted from the heat generating portion 110 of the heater body to the heater case via the elastic member 5. Moreover, it is preferable from the viewpoint of heat transfer suppression that the size of the non-heat generating portion 111 is set to be 2 mm or more larger than the portion of the elastic member 5 in contact with the non-heat generating portion 111 by verification with an actual machine. Have confirmed.

Further, the heater main body has a fixing portion 1120 fixed to the heater case, and the terminal 461 conducting to the heat generating portion 11 is fixed to the fixing portion 1120. According to this configuration, when the terminals are connected to turn on the power, for example, the terminal 461 is reliably supported against an external force acting on the terminal 461 when the male connector and the female connector are connected. Thus, it is possible to suppress the occurrence of defects such as deformation in the terminal 461 and the substrate unit 10.

The elastic member 5 is a separate part from the heater case. According to this, the durability of the elastic portion can be improved by configuring the elastic portion as a separate component from the heater case. The elastic force provided by the elastic part can be appropriately set and managed.

The base member 4 includes a plurality of protrusions 43 that protrude toward the back surface of the heater body located on the opposite side of the front surface of the heater body facing the vehicle interior. The heater body is supported by the heater case at a non-heat generating portion 112 where the heat generating portion 11 is not provided, and is installed so that the back surface of the heat generating portion 110 where the heat generating portion 11 is provided does not contact the plurality of protrusions 43.

According to this configuration, the substrate unit 10 is supported by the heater case at the non-heat generating portion 112 in a normal state that is normally used, and the back surface of the heat generating portion 110 does not contact the plurality of protrusions 43. For this reason, the heat transmitted from the heat generating part 110 to the base member 4 is greatly reduced as compared with the conventional apparatus in which the heat generating part 110 is in contact with the heater case.

For example, when an external force is applied to a heater main body supported by a heater case at a conventional heat generating portion by a human finger or an object, the heater main body is deformed, and depending on the degree of deformation, the heater body for the vehicle is deformed. Bugs and problems may occur. In the radiant heater device 1, when an external force is applied to the heater body in this way, the plurality of protrusions 43 protrude toward the back surface of the substrate portion 10, and thus the deformed substrate portion 10. The protrusion 43 can contact the back surface of the substrate 10 to support the substrate unit 10. Thereby, it can suppress that the board | substrate part 10 deform | transforms excessively.
