[0005] Various aspects of a vehicle heating device for solving the above problems will be described below. [Embodiment 1] A vehicle heating device that has a heater that heats using radiant heat and is attached to the interior of a vehicle, the vehicle housing the heater with the side of the heater facing the passenger compartment as the front side of the heater and the side of the heater opposite the side facing the passenger compartment as the back side of the heater, the vehicle heating device comprising: a case composed of an end wall facing the back side of the heater and a peripheral wall; and a lid portion positioned opposite the front side of the heater, the case and the lid portion being configured so that an air layer is interposed between the heater and the lid portion, the end wall comprising a porous member that contacts the back side of the heater and a plate material made of a resin molded product covering the side of the porous member opposite the side that contacts the heater.

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle heating device will be described below with reference to the drawings. In the following description, the forward direction of the vehicle is referred to as the front, and the backward direction is referred to as the rear. The left and right direction is the width direction of the vehicle, and corresponds to the left and right direction when the vehicle is moving forward.

[0016] <Vehicles and heating systems> As shown in Fig. 1, a heating device 10, which is one embodiment of a vehicle heating device, is attached to the interior of a vehicle 90. The heating device 10 is capable of heating by radiant heat, as will be described later.

[0017] In a passenger compartment 90a of a vehicle 90 illustrated in FIG. 1, a first seat 91 and a second seat 92 are arranged side by side in the left-right direction as front seats. The first seat 91 is the front left seat of the vehicle 90, and the second seat 92 is the front right seat of the vehicle 90. A center console 97 is arranged between the first seat 91 and the second seat 92 in the passenger compartment 90a. The center console 97 is also called a console box, a floor console, etc. An instrument panel 98 is arranged in front of the first seat 91 and the second seat 92. A front left door 93 of the vehicle 90 is provided with a first door trim 94 facing the first seat 91. A front right door 95 of the vehicle 90 is provided with a second door trim 96 facing the second seat 92.

[0018] 1, the heating device 10 can be attached to, for example, the center console 97 of the vehicle 90. There are no particular limitations on the object to be heated by the heating device 10. For example, the heating device 10 may be attached so as to radiate heat toward the thighs of a passenger sitting in a seat, or the heating device 10 may be attached so as to radiate heat toward the shins of a passenger sitting in a seat.

[0019] There is no limit to the number of heating devices 10 that the vehicle 90 is equipped with. One heating device 10 may be installed, or two or more heating devices 10 may be installed. When the heating device 10 is attached to the center console 97, it is preferable to arrange the heating device 10 as follows. For example, as shown in FIG. 1, the heating device 10 is attached to the surface of the center console 97 facing the first seat 91, and the heating device 10 is attached to the first door trim 94. For example, as shown in FIG. 1, the heating device 10 is attached to the surface of the center console 97 facing the second seat 92, and the heating device 10 is attached to the second door trim 96.

[0020] The center console 97, the first door trim 94, the second door trim 96, and the instrument panel 98 are examples of the interior of the vehicle 90. There are no particular limitations on the location where the heating device 10 is attached, as long as it is part of the interior of the vehicle 90. For example, the heating device 10 may be attached in a position where it can radiate heat toward passengers seated in the rear seats of the vehicle 90. Other specific examples of the interior include the rear surfaces of the seats, such as the first seat 91 and the second seat 92, and the ceiling.

[0021] As shown in Figures 3 and 4, the heating device 10 includes a heater 20. The heater 20 is capable of heating by radiant heat. The surface of the heater 20 facing the vehicle interior 90a is referred to as the front surface 21 of the heater 20. The surface of the heater 20 opposite to the surface facing the vehicle interior 90a is referred to as the back surface 22 of the heater 20. The surface of the heater 20 connecting the back surface 22 and the front surface 21 is referred to as the side surface 23.

[0022] The heating device 10 includes a case 30 that houses the heater 20. The heating device 10 includes a lid 40 that is disposed in a position facing the front surface 21 of the heater 20. The heating device 10 may also include a skin material 50.

[0023] As shown in FIGS. 2, 3, and 4, the heating device 10 can be attached to a mounting portion 99 provided in the interior of the vehicle 90. One example of the mounting portion 99 is a recess formed in the interior. The heating device 10 can be attached to the interior by fitting it into the mounting portion 99, which serves as a recess. The heating device 10 is preferably attached so that the front surface 21 of the heater 20 is recessed from the surface of the interior, i.e., is located on the opposite side of the interior surface from the passenger compartment 90a. As an example, the heating device 10 is attached so that the skin 50 or the lid 40 is flush with the surface of the interior. The heating device 10 may be attached so that the skin 50 or the lid 40 is recessed from the surface of the interior, or so that it protrudes into the passenger compartment 90a from the surface of the interior.

[0024] <Heater> The heater 20 generates heat by receiving power from, for example, a power source provided in the vehicle 90. In each drawing, the power source and the wiring between the power source and the heating device 10 are not shown.

[0025] The heater 20 is configured so that the front surface 21 can radiate heat. 3 and 4 show an arrow indicating a radiation direction D1, which is a direction from the heater 20 toward the vehicle interior 90a. An example of the radiation direction D1 is a direction perpendicular to the front surface 21 of the heater 20.

[0026] The heater 20 is, for example, a planar heater. The planar heater has a rectangular shape in a plan view. As another example, the heater 20 may be formed so that a rod-shaped heater has a serpentine shape on the same plane that forms the front surface 21.

[0027] <Case> 3 and 4, the case 30 is composed of an end wall 31 and a peripheral wall 32. The case 30 is box-shaped with an opening, and houses the heater 20 so that the front surface 21 of the heater 20 faces the opening. The end wall 31 is a wall that faces the back surface 22 of the heater 20. The peripheral wall 32 is a wall that surrounds the side surface 23 of the heater 20.

[0028] [End wall] The end wall 31 has a first end wall material 31F in contact with the back surface 22 of the heater 20, and a second end wall material 31S covering the surface of the first end wall material 31F opposite to the surface in contact with the heater 20.

[0029] In this embodiment, a two-layer end wall 31 made up of a first end wall material 31F and a second end wall material 31S is laminated on the back surface 22 of the heater 20. More specifically, the first end wall material 31F is laminated on the entire back surface 22 of the heater 20. The second end wall material 31S is laminated on the entire surface of the first end wall material 31F opposite to the surface laminated on the back surface 22.

[0030] The first end wall material 31F is a porous member. The second end wall material 31S is a plate material made of a resin molded product. Specific examples of porous members and plate materials include the following. (porous material) As the porous member, for example, a fibrous body, a foam, etc. can be used. The porous member is not particularly limited as long as it exhibits heat insulating properties, and examples thereof include the following. As the fibrous body, a nonwoven fabric, a woven fabric, etc. made of polyester fiber, polyolefin fiber, aramid fiber, glass fiber, cellulose fiber, nylon fiber, vinylon fiber, rayon fiber, etc. can be used. As the foam, a polyethylene foam, a polyurethane foam, a polyolefin foam, a polystyrene foam, etc. can be used. As the porous member, a foam is preferred, and among foams, polyethylene foam is more preferred.

[0031] (plate material) The plate material is a molded product made of a material with high thermal insulation properties, such as polypropylene or polyethylene. The method for molding the plate material is not particularly limited, and examples thereof include injection molding, extrusion molding, and vacuum molding. One example is a solid plate material, but a hollow plate material may also be used. As the plate material, a resin molded product made of polypropylene is preferred.

[0032] [Peripheral wall] The peripheral wall 32 includes, for example, a first peripheral wall material 32F that contacts the side surface 23 of the heater 20. The peripheral wall 32 may also include a second peripheral wall material 32S that covers the surface of the first peripheral wall material 32F opposite to the surface that contacts the heater 20.

[0033] In this embodiment, a two-layer peripheral wall 32 made up of a first peripheral wall material 32F and a second peripheral wall material 32S surrounds the side surface 23 of the heater 20. For example, the first peripheral wall material 32F contacts the side surface 23 of the heater 20 along the entire periphery thereof. A second peripheral wall material 32S is laminated over the entire surface of the first peripheral wall material 32F opposite the surface contacting the side surface 23.

[0034] The first peripheral wall material 32F is a porous material. As the porous material, the same porous material as exemplified as the porous material constituting the first end wall material 31F can be used. The porous material constituting the first peripheral wall material 32F may be the same type of porous material as the porous material constituting the first end wall material 31F, or may be a different type of porous material.

[0035] When the porous member constituting the first end wall material 31F and the porous member constituting the first peripheral wall material 32F are the same type of porous member, the first end wall material 31F and the first peripheral wall material 32F may be an integrated member, or the first end wall material 31F and the first peripheral wall material 32F may be separate members.

[0036] The second peripheral wall material 32S is a plate material made of a resin molded product. The plate material may be the same as the plate material exemplified for the second end wall material 31S. The plate material for the second peripheral wall material 32S may be the same type of plate material as the plate material for the second end wall material 31S, or may be a different type of plate material.

[0037] When the plate material constituting the second end wall material 31S and the plate material constituting the second peripheral wall material 32S are the same type of plate material, the second end wall material 31S and the second peripheral wall material 32S may be molded as a single unit, or the second end wall material 31S and the second peripheral wall material 32S may be separate molded products. When the plate material constituting the second end wall material 31S and the plate material constituting the second peripheral wall material 32S are different types of plate material, the second end wall material 31S and the second peripheral wall material 32S may be molded as a single unit by, for example, two-color molding.

[0038] <Lid> 3 and 4, the cover part 40 includes a first cover member 40S. The first cover member 40S is configured to close the opening of the case 30.

[0039] The first cover member 40S is, for example, a plate material made of a resin molded product. The plate material may be the same as the plate material exemplified for the second end wall member 31S. The plate material for the first cover member 40S may be the same type of plate material as the plate material for the second end wall member 31S, or may be a different type of plate material.

[0040] The lid portion 40 may have through holes 42 penetrating in the radiation direction D1, which is the direction from the heater 20 toward the passenger compartment 90a. Figures 2 and 4 show, as an example, eight through holes 42 and a lattice portion 41, which is a portion of the lid portion 40 where no through holes 42 are formed. The shape, size, and number of the through holes 42 are not particularly limited.

[0041] The lid portion 40 may include a second lid portion 40F laminated on the first lid portion 40S. The second lid portion 40F is laminated, for example, on the surface of the first lid portion 40S facing the heater 20. If the lid portion 40 has through holes 42, the second lid portion 40F can be laminated on the first lid portion 40S at the lattice portion 41 of the lid portion 40.

[0042] The second cover member 40F is, for example, a porous member. The porous member may be the same as the porous member exemplified for the first end wall member 31F. The porous member for the second cover member 40F may be the same type of porous member as the porous member for the first end wall member 31F, or may be a different type of porous member.

[0043] The case 30 and the lid 40 are configured so that an air layer 11 is interposed between the heater 20 and the lid 40. Specifically, as shown in Figures 3 and 4, the lid 40 is configured to be disposed at a position spaced a specified distance from the front surface 21 of the heater 20 in the radiation direction D1. This defines the air layer 11 by the front surface 21 of the heater 20, the peripheral wall 32 of the case 30, and the lid 40. If the lid 40 has a through-hole 42, the air layer 11 communicates with the through-hole 42.

[0044] <Skin material> The upholstery material 50 may be a material used for vehicle interiors. Specific examples of the upholstery material 50 include fabrics, nonwoven fabrics, knitted fabrics, resin sheets, synthetic leather, artificial leather, and natural leather. The upholstery material 50 may have a pattern or the like to enhance its design. The upholstery material 50 may have a coarse mesh structure.

[0045] 2, 3 and 4, for example, a skin material 50 may be attached to the surface of the lid portion 40. When the lid portion 40 has a through-hole 42, as shown in Fig. 4, the heater 20 and the skin material 50 face each other at a position corresponding to the through-hole 42, with the air layer 11 and the through-hole 42 interposed therebetween.

[0046] As shown in FIGS. 3 and 4, for example, a skin material 50 may be attached to the surface of the peripheral wall 32. The covering material 50 may be of the same type as or a different type from the interior covering to which the heating device 10 is attached. A covering material 50 that is integrated with the interior covering and has an attachment portion 99 can also be attached to the surface of the lid portion 40.

[0047] <Operation of this embodiment> When the heating device 10 is operated, the heater 20 generates heat. The generated heat is radiated from the front surface 21 of the heater 20. The radiant heat is radiated to the occupants of the vehicle 90 via the lid portion 40 and the covering material 50. At this time, since the air layer 11 is interposed between the heater 20 and the lid portion 40 facing the front surface 21 of the heater 20, the temperature rise of the lid portion 40 is suppressed compared to when the heater 20 and the lid portion 40 are in direct contact.

[0048] Heat generated in the heater 20 is radiated from the front surface 21 and also dissipated to components present around the heater 20. In the heating device 10 of this embodiment, the end wall 31 in contact with the back surface 22 of the heater 20 has thermal insulation properties, thereby suppressing heat dissipation in the direction opposite to the direction from the heater 20 toward the passenger compartment 90a. Furthermore, the peripheral wall 32 in contact with the side surface 23 of the heater 20 has thermal insulation properties, thereby suppressing heat dissipation in the direction perpendicular to the direction from the heater 20 toward the passenger compartment 90a.

[0049] <Effects of this embodiment> (1) According to this embodiment, the end wall 31 has a two-layer structure made of a porous member and a plate material, and therefore the end wall 31 has excellent heat insulation properties. This makes it possible to suppress heat radiation from the heater 20 in the direction opposite to the direction from the heater 20 toward the passenger compartment 90a. This reduces heat loss from the heater 20, thereby improving heating efficiency.

[0050] (2) Because the air layer 11 is present between the heater 20 and the lid portion 40, the temperature of the lid portion 40 is less likely to become excessively high compared to when the heater 20 and the lid portion 40 are in direct contact with each other. As a result, even if an occupant of the vehicle 90 touches the lid portion 40, the heat felt by the occupant through contact with the lid portion 40 can be reduced. According to this embodiment, the heat felt by the occupant through contact with the lid portion 40 when the occupant touches the lid portion 40 can be reduced without employing a configuration for detecting contact with an occupant or a processing circuit that reduces the output of the heater based on contact with the occupant.

[0051] (3) When the peripheral wall 32 has a two-layer structure made of a porous member and a plate material, heat radiation from the heater 20 in a direction perpendicular to the direction from the heater 20 toward the passenger compartment 90a can be suppressed. The peripheral wall 32 in contact with the side surface 23 in addition to the end wall 31 in contact with the back surface 22 of the heater 20 can further reduce heat loss from the heater 20, thereby further improving heating efficiency.

[0052] (4) When the lid portion 40 has the through-hole 42, even if an occupant of the vehicle 90 touches the lid portion 40, the area of ​​contact with the lid portion 40 can be made smaller compared to when the lid portion 40 does not have the through-hole 42. As a result, even if an occupant of the vehicle 90 touches the lid portion 40, the heat felt by the occupant through contact with the lid portion 40 can be reduced. Alternatively, if the occupant touches the position corresponding to the through-hole 42 and only comes into contact with the upholstery material 50, contact with the lid portion 40 can be avoided. Furthermore, in this embodiment, an air layer 11 is interposed between the heater 20 and the lid portion 40. Due to the presence of the air layer 11, even if the occupant's finger or the like touches the position corresponding to the through-hole 42, the finger or the like is unlikely to reach the heater 20, thereby preventing contact between the occupant and the heater 20.

[0053] (5) When the heater 20 is a planar heater, it is possible to efficiently radiate heat to the passenger compartment 90a. (6) When the heating device 10 of this embodiment is attached to the center console 97, the heating device 10 can be placed closer to the occupants than when the heating device 10 is attached to the instrument panel 98. When the heating device 10 is close to the occupants in this manner, the occupants can easily feel the heating effect even if the output of the heater 20 is kept low. Because the heating device 10 of this embodiment has little heat loss, it can provide efficient heating even if the output of the heater 20 is kept low.

[0054] On the other hand, if the heating device 10 is close to the occupant, the occupant may easily come into contact with the lid portion 40. In this regard, with the heating device 10 of the present embodiment, the temperature of the lid portion 40 is unlikely to become excessively high, ensuring safety.

[0055] (7) When a pair of heating devices 10 are installed so that the occupant is sandwiched between them, for example, when the heating devices 10 are installed on both the center console 97 and the first door trim 94, the occupant of the vehicle 90 can be heated from both the left and right sides. This configuration allows the occupant to more easily feel the heating effect.

[0056] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0057] In the above embodiment, the end wall 31 has a two-layer structure composed of the first end wall material 31F and the second end wall material 31S. However, the end wall is not limited to such a two-layer structure and may have a multi-layer structure of three or more layers. For example, another plate material or the like may be laminated on the surface of the second end wall material 31S opposite to the surface laminated on the first end wall material 31F. Similarly, the peripheral wall may also have a multi-layer structure of three or more layers.

[0058] The end wall may have a space defined therein. An example will be described with reference to FIG. 5 shows a heating device 110. In the heating device 110, the same components as those in the above embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0059] The heating device 110 includes a third end wall material 133. The third end wall material 133 is, for example, a plate material made of a resin molded product. The third end wall material 133 is attached to the second end wall material 31S. Specifically, the third end wall material 133 is attached to the surface of the second end wall material 31S opposite the surface laminated to the first end wall material 31F. A recess is formed in the surface of the third end wall material 133 facing the second end wall material 31S. Due to the presence of this recess, the end wall of the third end wall material 133 is positioned away from the second end wall material 31S in the direction opposite to the radiation direction D1. As a result, as shown in FIG. 5 , a back air space 134 is defined by the third end wall material 133 and the second end wall material 31S. For example, the back air space 134 is a closed space formed between the third end wall material 133 and the second end wall material 31S.

[0060] In the heating device 110, in addition to the first end wall material 31F and the second end wall material 31S, a back air layer 134 and a third end wall material 133 are arranged in the opposite direction to the radiation direction D1 relative to the heater 20. The end wall 131 in this heating device 110 is composed of the first end wall material 31F, the second end wall material 31S, and the third end wall material 133. The end wall 131 has the back air layer 134 as a space partitioned therein. This makes it possible to further suppress heat radiation from the heater 20 in the direction opposite to the radiation direction D1.

[0061] In the above modified example, the heating device 110 is configured to further include the third end wall member 133 to define the rear air space 134. However, a space located in the opposite direction to the radiation direction D1 relative to the heater 20 can also be defined by a configuration different from this. One example will be described using Figure 6.

[0062] 6 shows a heating device 210. In the heating device 210, the same components as those in the above embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate. The heating device 210 includes a second end wall material 231S instead of the second end wall material 31S in the above embodiment. The end wall 231 of the heating device 210 is made up of a first end wall material 31F and a second end wall material 231S.

[0063] 6, the second end wall material 231S has a wall portion 235 and a protrusion 236. The wall portion 235 covers the surface of the first end wall material 31F opposite to the surface that contacts the heater 20. The protrusion 236 protrudes from the wall portion 235 toward the first end wall material 31F. The end of the protrusion 236 that faces the first end wall material 31F contacts the first end wall material 31F.

[0064] The second end wall material 231S preferably has a plurality of protrusions 236. The plurality of protrusions 236 are preferably arranged at intervals. With this configuration, small chambers 237 are defined between adjacent protrusions 236, between adjacent protrusions 236 and the peripheral wall 32, and between the wall portion 235 and the first end wall material 31F. In other words, the end wall 231 has small chambers 237 as spaces defined therein. For example, the small chambers 237 are closed spaces formed between the second end wall material 231S and the first end wall material 31F. The plurality of small chambers 237 may be connected together, or the plurality of small chambers 237 may be independent of each other.

[0065] In addition, when the second end wall material 231S has multiple convex portions 236, the shape and size of each convex portion 236 may be equal to or different from each other, but it is preferable that the protruding length of each convex portion 236 from the wall portion 235 is equal to each other.

[0066] In the heating device 210, like the rear air layer 134 in the heating device 110, the small chamber 237 is arranged in the opposite direction to the radiation direction D1 relative to the heater 20. As a result, similar to the heating device 110, heat radiation from the heater 20 in the direction opposite to the radiation direction D1 can be further suppressed.

[0067] Furthermore, in the heating device 210, by bringing the protrusions 236 into contact with the first end wall material 31F, the contact area between the second end wall material 231S and the first end wall material 31F can be made smaller compared to the case where the second end wall material 31S is laminated over the entire surface of the first end wall material 31F as in the above embodiment. This makes it possible to more effectively suppress heat radiation from the heater 20 in the direction opposite to the radiation direction D1.

[0068] The end walls having a partitioned space inside can also be constructed using a plate material with a hollow structure such as plastic cardboard. For example, a porous member, a plate material made of a hollow resin molded product, and a plate material made of a solid resin molded product may be stacked in this order on the back surface 22 of the heater 20.

[0069] A space may be defined inside the peripheral wall of the case. For example, both the end wall and the peripheral wall may have a space defined inside. Alternatively, either the end wall or the peripheral wall may have a space defined inside.

[0070] In the above embodiment, the case 30 and the lid 40 are provided as separate components, but the lid and the peripheral wall may be integrally molded. In this case, the end wall may be a separate molded part from the molded part including the lid and the peripheral wall. [Explanation of symbols]
