<Third Embodiment>
In the first embodiment, in the fourth mode for keeping the bedding at the target temperature before going to bed, the heating means is controlled to reach the target temperature based on the temperature detected at the installation position. After heating to a temperature higher than the temperature, the target temperature may be maintained while cooling.
3rd Embodiment is described using FIG.14 and FIG.15.
The third embodiment differs from the first embodiment in the content of control when the fourth mode is selected, and the same reference numerals are used for the same configurations as in the first embodiment.
The configuration of the control unit of the third embodiment has the same configuration as that of the control unit 171 of the first embodiment (the program of the fourth mode is different from that of the first embodiment). For the sake of distinction, although not shown in the drawing, the code of the control unit in the third embodiment is "2171".
Also, the position of the temperature sensor is changed from the position of the temperature sensor 134 in the first embodiment, and the temperature sensor 2134 will be described in the third embodiment.

Here, as described above, since the second step indicated by "2" changes depending on the room temperature, it does not become a constant time like the first step indicated by "1". The second time "2Ti2", which is the total operating time, is predetermined (unless the user turns off the power at any time), but the time of the second step depends on the room temperature. Therefore, the time of the third step indicated by "3" also varies depending on the room temperature. However, the time from the start to the end of the fourth mode is constant.

A description will be given below with reference to the flowchart of FIG. 15 .
The controller 2171 starts when the user selects the fourth mode.
When the control unit 2171 starts, the room temperature 2Te0, the target temperature 2Te1, etc. are cleared to 0, and the timer is reset. The heater 131 of 13 and the drive motor of the blower unit 122 are turned on (S202), and the timer is started (S203).
At this time, the temperature of the hot air discharged from the nozzle main body 33 of the hose body 3 (heater ON state) is constant and is "2Te2", which is higher than the target temperature 2Te1.
When the elapsed time 2Ti of the timer reaches the first time "2Ti1"("Yes" in S204), the control unit 2171 turns off the heater 131 regardless of the room temperature 2Te0 acquired in S201 (S205). , the target temperature 2Te1 corresponding to the room temperature 2Te0 is read from the storage unit (S206).
As a result, the temperature of the bedding falls from the temperature 2Te2 of the hot air discharged from the nozzle main body 33 .

The storage unit stores the room temperature 2Te0 and the target temperature 2Te1 in association with each other. Here, the room temperature 2Te0 is divided into three temperature ranges, and a target temperature 2Te1 is set for each temperature range.
When the room temperature 2Te0 measured by the temperature sensor 2134 is less than 7 [°C], the target temperature 2Te1 is set to a temperature within the range of 50 [°C] to 60 [°C] (for example, 55 [°C]), When the room temperature 2Te0 measured by the temperature sensor 2134 is 7 [° C.] or more and less than 13 [° C.], the target temperature 2Te1 is a temperature within the range of 45 [° C.] or more and 55 [° C.] or less (for example, 50 [° C.]). ), and when the room temperature 2Te0 measured by the temperature sensor 2134 is 13[°C] or higher, the target temperature 2Te1 is a temperature in the range of 40[°C] to 50[°C] (for example, 45[°C]). is set to

When the temperature 2Te measured by the temperature sensor 2134 drops to the target temperature 2Te1 (“Yes” in S207), the controller 2171 controls the heater 131 so that the temperature 2Te measured by the temperature sensor 2134 maintains the target temperature 2Te1. is turned ON/OFF for feedback control (S208).
When the elapsed time 2Ti of the timer reaches "2Ti2", which is the second time ("Yes" in S204), the control unit 2171 turns off the drive motor (S210) and ends the process.
In step S210, for example, when the heater 131 is ON, the drive motor may be turned OFF at the same time as the drive motor or after a predetermined time has elapsed after the heater 131 is turned OFF.
When the control unit 2171 receives an operation from the user to terminate the driving in the fourth mode, the control unit 2171 interrupts and terminates the processing.

As described above, after heating to a temperature (“2Te2”) higher than the target temperature 2Te1, the heater 131 is turned off to maintain the target temperature 2Te1 while naturally cooling, and the drive motor is operated at approximately the maximum output value. It suffices to suppress the operation to 20 to 30 [%], and the noise from the air blower 1012 can be reduced while suppressing the power consumption related to the heater 131 and the motor drive. In addition, temperature unevenness in the bedding (for example, the gap between the comforter and the mattress, the gap between the comforter and the mattress, etc.) can be reduced.
The target temperature 2Te1 here is set higher than the target bed temperature (in the range of 31 [° C.] or more and 35 [° C.] or less) at which the sleeping person feels comfortable when entering the bedding, considering the room temperature. It has become. For example, when the room temperature 2Te0 is less than 7 [°C], the target temperature 2Te1 is 10 [°C] higher than when the room temperature 2Te0 is 13 [°C] or higher. As a result, it is possible to provide the above-described target bed temperature that is comfortable for the user regardless of the season (season) of use, except for summer.

The drying apparatus of the third embodiment described here is a drying apparatus that performs a mode of heating bedding before going to bed and keeping it at a target temperature.
As such a drying device, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 5-345098. However, since this drying apparatus dries the futon at a high temperature even when the room temperature is high, such as in the summer, it takes a long time to lower the temperature of the futon (to finish the futon), which tends to increase the electricity bill. In addition, since the room temperature is detected after the futon is dried, the temperature sensor installed near the heater cannot detect the accurate room temperature due to the high temperature of the atmosphere around the futon. (Because the optimal air blowing time cannot be set), there is a risk that the futon cannot be kept in a comfortable temperature range.
The drying apparatus according to the third embodiment determines a plurality of types of target temperature based on the room temperature before heating when executing the mode of heating the bedding before going to bed and keeping it at the target temperature. As a result, when used in similar temperature environments, the temperature of the bedding is maintained at a substantially constant temperature, and regardless of the season or time, the temperature variation of the material to be dried is reduced according to the room temperature at the time of use. can.
The drying apparatus according to the third embodiment that performs such control is an invention capable of reducing variations in temperature of the material to be dried (bedding, etc.) after drying.

2. Position of Temperature Sensor In the third embodiment, a thermistor is used as the temperature sensor 2134, a PTC heater is used as the heater 131, and the overall shape is a thin box. As shown in FIG. 16(a), the temperature sensor 2134 is positioned such that the detection portion 2134a is 10 [mm] away from the upper surface of the heater 131 (in the direction in which air is blown) ("L1" in the drawing). and arranged parallel to the upper surface 131 b of the heater 131 . It should be noted that the detection portion 2134a is preferably within a range of 8 to 15 [mm] from the upper surface of the heater 131 from the viewpoint of reliability of the measured temperature.
16(b), the temperature sensor 2134 has a detection portion 2134a located at a position 20 [mm] away from the inner surface of the heating cylinder 132 ("L2" in the figure). It is It should be noted that the detection portion 2134a is preferably within a range of 15 to 25 [mm] from the inner surface of the heating cylinder 132 from the viewpoint of the reliability of the measured temperature.
As a result, although the temperature sensor 2134 is arranged above the heater 131 and measures the temperature of the air heated by the heater 131, as shown in Table 1, the air is blown out from the nozzle body 33. The correlation between the temperature of the hot air (“nozzle outlet temperature” in the table) and the temperature measured by the temperature sensor 2134 (“thermistor temperature” in the table) is improved. That is, the variation in the temperature measured by the temperature sensor 2134 can be reduced with respect to the temperature in the nozzle body 33 .

ここでの加熱部１３の加熱筒体１３２は、加熱筒体１３２の内壁から内側に離間し、温風が通過する方向と平行なリブ壁１３２ａが設けられ、温度センサ２１３４はリブ壁１３２ａに沿って固定されている。これにより、温度センサ２１３４の検出部分２１３４ａの位置が不動となり、安定した温度を測定できる。また、リブ壁１３２ａに設けるため、製造時の検出部分２１３４ａの位置のばらつきを小さくできる。 Therefore, in the fourth mode, although the target temperature is controlled based on the temperature measured by the temperature sensor 2134 arranged near the heater 131, the actual temperature inside the bedding can be controlled with high accuracy.

The heating cylinder 132 of the heating unit 13 here is spaced inward from the inner wall of the heating cylinder 132, and is provided with a rib wall 132a parallel to the direction in which the hot air passes. is fixed. As a result, the position of the detection portion 2134a of the temperature sensor 2134 becomes immovable, and stable temperature measurement can be performed. Moreover, since it is provided on the rib wall 132a, variations in the position of the detection portion 2134a during manufacturing can be reduced.

<Fourth Embodiment>
In the first embodiment, the heater 131 is provided in the heating cylinder 132, and the temperature of the heater 131 is indirectly measured by the temperature sensor 133. may
Conventionally, heaters used vary in size, so the distance between the heater in the heating cylinder and the temperature sensor is not constant, and there is a problem that the temperature of the heater cannot be detected accurately. Since the temperature (applied power) of the heater is adjusted based on the detection result of the temperature sensor, the temperature of the hot air blown out from the heating unit is unstable in the conventional method.
In the fourth embodiment, by providing the elastic body, for example, even if the heater size varies, the distance between the heater and the temperature sensor becomes constant, and the temperature of the heater can be accurately measured by the temperature sensor.

1. Overall The fourth embodiment will be described mainly with reference to FIGS. 17 to 19. FIG.
Note that the fourth embodiment differs from the first embodiment in the heating unit 3013, and the same reference numerals are used for the same configurations as in the first embodiment even if they are not shown in FIGS.
The heating unit 3013 includes a heating cylinder 3130, a heater 131 arranged in the heating cylinder 3130, a temperature sensor 133 provided on the outer surface of the heating cylinder 3130, and biasing the heater 131 toward the temperature sensor 133. and an elastic body 3200 .
The heating cylinder 3130 constitutes a case that houses the heater 131, and the temperature sensor 133 is attached to the case. Also, although one elastic body 3200 is used here, a plurality of elastic bodies 3200 may be used.
The heater 131 is a so-called ceramic heater (PTC heater) in which a heating element (PTC element) is sandwiched between radiator plates and an electrode sheet is joined to the radiator plates. The heater 131 has a low (thin) rectangular parallelepiped shape with a low height (thickness). Here, a temperature sensor 133 is provided on one end face (this end face is defined as a first end face) 131c which has a rectangular shape in plan view and is perpendicular to the longitudinal direction, and the other end face (this end face is referred to as a first end face) perpendicular to the longitudinal direction. An elastic body 3200 is provided on the side of 131d (which is assumed to be the second end surface).
Note that the end faces in the short direction of the heater 131 may be the first end face and the second end face, and the planar shape of the heater 131 may be square. That is, the first end face and the second end face may be end faces positioned on a predetermined direction (virtual straight line) with respect to the heater 131 .
The temperature sensor 133 measures the temperature of the air heated by the heater 131 , and measures the temperature of a case (partition wall portion 3131 k described later) in contact with the heater 131 . Note that there is a correlation between the temperature of the air heated by the heater 131 and the temperature of the case (the partition wall portion 3131k), and the correlation is obtained in advance by tests or the like. The temperature sensor 133 is, for example, a bimetal type.

2. Each part (1) Heating cylinder The heating cylinder 3130 consists of the lower cylinder 3131 located in the blower part 12 side, and the upper cylinder 3132 located in the hose body 3 side here. When the heater 131 is arranged in the lower cylinder 3131, the projecting portions 3131m and 3132m of the lower cylinder 3131 and the upper cylinder 3132 are connected to each other by screws (not shown) or the like.

The lower cylindrical body 3131 mainly functions to accommodate the heater 131 . The lower cylindrical body 3131 has an inner peripheral surface shape that matches the external shape of the heater 131 . Here, the heater 131 has a rectangular shape in plan view, and the inner peripheral surface shape of the lower cylindrical body 3131 has a rectangular shape in cross section.
The temperature sensor 133 is attached to the wall portion 3131 a of the lower cylinder 3131 facing the first end surface 131 c of the heater 131 . The temperature sensor 133 here is inserted and fixed in the recessed portion 3131b of the wall portion 3131a. The temperature sensor 133 is fixed in contact with the bottom of the recessed portion 3131b. As a result, variations in temperature detection accuracy between individual drying devices can be reduced.

A support portion 3131d that supports the elastic body 3200 is provided on the inner surface of the wall portion 3131c of the lower cylinder 3131 that faces the wall portion 3131a. Note that the support portion 3131d is referred to as a lower support portion 3131d in order to distinguish it from an upper support portion 3132c which will be described later.
The elastic body 3200 here is inserted between the heater 131 and the wall portion 3131c from the same direction as the installation direction of the heater 131 to the lower cylindrical body 3131 . The installation direction of the heater 131 is the direction in which the cylinder axis of the heating cylinder 3130 extends, and is the direction from the upper cylinder 3132 to the lower cylinder 3131 . The insertion direction of the elastic body 3200 is also the same.
The lower support portion 3131d supports the elastic body 3200 from the side opposite to the direction in which the elastic body 3200 is inserted. Here, the lower support portion 3131d is supported from the blower portion 12 side. In addition, the extending direction of the cylinder axis of the heating cylinder 3130 may be defined such that the air blower 12 side is the lower side and the hose body 3 side is the upper side.
As shown in FIG. 18A, the lower support portion 3131d is composed of one or more protruding portions 3131e that protrude from the inner surface of the wall portion 3131c toward the heater 131 side. There are two projecting portions 3131e, for example, projecting in a plate shape.

On the inner surface of the wall portion 3131c, movement of the elastic body 3200 in a direction orthogonal to the direction in which the elastic body 3200 is inserted and the direction in which the elastic body 3200 biases the heater 131 (the lateral direction of the heater 131) is provided. A regulation portion 3131f for regulation is provided. Here, the restricting portions 3131f are provided on both sides of the elastic body 3200 . The restricting portion 3131f is composed of a pair of rib portions 3131g extending on both sides of the elastic body 3200 in the insertion direction. As shown in FIG. 18(a), the lower ends of the pair of rib portions 3131g are connected to projecting portions 3131e of the lower support portion 3131d. The projecting portion 3131e is reinforced by a rib portion 3131g. The pair of rib portions 3131g also serve as guide portions for guiding the insertion of the elastic body 3200. As shown in FIG.

The lower cylindrical body 3131 has a heater support portion 3131h that protrudes inward and supports the heater 131 from below, and a groove 3131j for the electrical connection portion 131a of the heater 131 . The lower cylindrical body 3131 has a partition wall portion 3131k connected to the bottom of the recessed portion 3131b on the wall portion 3131c side with respect to the wall portion 3131a. More precisely, the heater 131 is accommodated in the space formed by the walls other than the wall 3131a and the partition wall 3131k. That is, the part where the temperature sensor 133 is provided in the case housing the heater 131 is the partition wall portion 3131k.
A thermal fuse 3135 is provided on the partition wall portion 3131k on the side of the upper cylinder 3132 . A thermal fuse 3135 operates to cut off the current when the temperature of the heater 131 rises excessively. The partition wall portion 3131k may be configured to be the wall portion of the lower cylindrical body, and in this case, the temperature fuse 3135 can be provided outside the wall portion.

An elastic body 3200 is supported on the inner surface of a wall portion 3132b that constitutes the upper cylinder 3132 and is located above the wall portion 3131c of the lower cylinder 3131 from the opposite side (upper side) of the lower support portion 3131d. A support portion 3132c is provided. The support portion 3132c is referred to as an upper support portion 3132c to distinguish it from the lower support portion 3131d.
The upper support portion 3132c abuts on the bent portion 3230 of the elastic body 3200 from the direction in which the elastic body 3200 is inserted. The upper support portion 3132c is composed of a rib portion 3132d that protrudes inward from an intermediate portion of a virtual line extending from the pair of rib portions 3131g and extends in the insertion direction. This prevents the elastic body 3200 from coming out from between the heater 131 and the lower cylindrical body 3131 in the direction opposite to the insertion direction, so that the heater 131 can be biased toward the temperature sensor 133 for a long period of time.

The upper cylindrical body 3132 has a heater support portion 3132f that supports the heater 131 from above. The heater support portion 3132f is configured by a rib that protrudes inward from the inner peripheral surface and extends along the insertion direction of the heater 131 .
The upper cylindrical body 3132 has a mounting portion 3132g for mounting the cover portion 19, as shown in FIG. The mounting portion 3132g is configured by an outer flange projecting radially outward from the upper edge. A mounting portion 3132g of the upper cylindrical body 3132 has grooves for fixing and supporting the temperature sensors 2133 and 2134 . The temperature sensors 2133 and 2134 are, for example, thermistors, the temperature sensor 2133 is for detecting an abnormal temperature of the heater 131, and the temperature sensor 2134 is for controlling the hot air temperature.
The upper cylinder 3132 has a rib wall 3132k inside the wall 3132a located above the wall 3131a of the lower cylinder 3131 corresponding to the partition wall 3131k. A lower end portion of the rib wall 3132k is connected to the wall portion 3132a via a connecting portion 3132j. The connecting portion 3132 j also has a function of supporting the thermal fuse 3135 of the lower cylinder 3131 .

(2) Elastic Body The elastic body 3200 is inserted between the heater 131 and the wall portion 3131c facing the wall portion 3131a (partition wall portion 3131k) where the temperature sensor 133 is arranged. force on. Thereby, the distance between the temperature sensor 133 and the first end surface 132c of the heater 131 can be made constant. That is, the first end surface 132c of the heater 131 contacts the wall portion 3131a (partition wall portion 3131k), and the cover surface of the temperature sensor 133 is arranged at a fixed position with respect to the wall portion 3131a (partition wall portion 3131k). , the distance between the temperature sensor 133 and the first end surface 132c of the heater 131 is constant even if the size of the heater 131 varies. Here, the first end surface 132c of the heater 131 is urged by the elastic body 3200 so as to come into contact with the partition wall portion 3131k.

Hereinafter, description will be made mainly using FIG. 18(b).
The elastic body 3200 is formed by bending or bending a thin metal plate, for example, and has a so-called plate spring structure. The elastic body 3200 has at least an elastic deformation portion 3210 arranged between the heater 131 and the wall portion 3131c.
The elastically deformable portion 3210 is elastically deformed in response to a change in the distance between the heater 131 and the wall portion 3131c, and generates an urging force in the direction of increasing the distance between the heater 131 and the wall portion 3131c.
The elastically deforming portion 3210 has a first side portion 3211, a second side portion 3212, and a connecting portion 3213 that are inclined with respect to the insertion direction of the elastic body 3200, and has a "V" shape as a whole. The height of the elastic deformation portion 3210 (the distance from the plane of the connecting portion 3213 when the V-shaped opening side is placed on the plane) is set larger than the distance between the heater 131 and the wall portion 3131c. This generates a force that urges the heater 131 toward the wall portion 3131a.
Here, the connecting portion 3213 contacts one side of the heater 131 and the wall portion 3131c (here, the second end face 131d of the heater 131), and the end portion 3211a of the first side portion 3211 opposite to the connecting portion 3213. The connecting portion 3213 of the second side portion 3212 and the end portion 3212a opposite to the connecting portion 3213 are connected directly or indirectly (here, indirectly due to an extending portion 3220 described later) to the other of the heater 131 and the wall portion 3131c ( Here, it is the wall portion 3131c). Note that the end portion 3211a of the first side portion 3211 constitutes a contact portion because it contacts the heater 131 or the wall portion 3131c indirectly or directly. The symbol 3211a is also used for this contact portion.

In the elastically deformable portion 3210, when the distance between the heater 131 and the wall portion 3131c is small, the distance between the end portion 3211a of the first side portion 3211 and the end portion 3212a of the second side portion 3212 is increased, or the first side portion 3211 and/or the second side portion 3212 is elastically deformed such as curved in the thickness direction. An urging force is generated by the restoring force of this elastic deformation.
The end portion 3211a of the first side portion 3211 here is folded back to the side opposite to the second side portion 3212 . This folded portion is referred to as a folded portion 3214 . As a result, the end portion 3211a can be moved smoothly, and the end portion 3211a can be easily moved in the distance direction with respect to the end portion 3212a on the second side portion 3212 side. In particular, by providing an extension portion 3220, which will be described later, the end portion 3211a can slide along the extension portion 3220, and can move more smoothly.

The elastic body 3200 has an extending portion 3220 extending from the end portion 3212a of the second side portion 3212 to the side opposite to the insertion direction (the side where the first side portion 3211 exists). The extension 3220 here extends along the insertion direction. The extension 3220 extends parallel to the direction of insertion, that is, straight. An end portion 3212a of the second side portion 3212 is also a connecting portion between the second side portion 3212 and the extending portion 3220, and the connecting portion is also denoted by "3212a".
The second side portion 3212 is inclined away from the extending portion 3220 as it moves from the connecting portion 3212a with the extending portion 3220 to the first side portion 3211 side. Thereby, the insertion can be easily performed by inserting the elastic body 3200 from the connecting portion 3212a side.
The extending portion 3220 extends upward longer than the folded portion 3214 . This prevents the end portion 3211a of the first side portion 3211 from being caught on the wall portion 3131c or the second end face 131d of the heater 131 when inserting the elastic body 3200, so that the elastic body 3200 can be smoothly inserted. Further, when inserting, the extending portion 3220 can be slid while being in contact with the inner surface of the wall portion 3131c or the first end surface of the heater 131 (here, the wall portion 3131c). Thereby, the elastic body 3200 can be easily inserted. In addition, even when the elastically deformable portion 3210 is elastically deformed during insertion, the end portion 3211a of the first side portion 3211 contacts the extending portion 3220 and can move along the extending portion 3220, thereby smoothly moving the elastic body 3200. can be inserted.

The elastic body 3200 has a bending portion 3230 that bends toward the side where the elastic deformation portion 3210 exists, at the end portion of the extending portion 3220 opposite to the connecting portion 3212a. As a result, when the elastic body 3200 is inserted, the bent portion 3230 is bent to the side opposite to the wall portion 3131c, so that the bent portion 3230 does not contact the wall portion 3131c and the elastic body 3200 can be smoothly inserted. can. In addition, when inserting the elastic body 3200, the elastic body 3200 can be easily inserted by pushing the bent portion 3230 inward.
The bent portion 3230 is located above the upper surface 131e of the heater 131, as shown in FIG. 17(b). As a result, the bent portion 3230 does not come into contact with the heater 131 when the elastic body 3200 is inserted. Further, when the elastic body 3200 is removed, it can be easily performed by using the bent portion 3230 .

3. Regarding Elastic Body The elastic body 3200 has the V-shaped elastically deforming portion 3210, the extending portion 3220, and the bending portion 3230, but the elastic body may have the following configuration.
The elastic body 3200 has a plate spring structure made of metal or a resin containing heat-resistant resin or the like, and has an extending portion 3220 extending in the insertion direction, and an extending portion 3220 positioned on the distal end side when the elastic body 3200 is inserted. It integrally has an elastic deformation portion 3210 continuous to the end portion 3212a. As a result, the elastic body 3200 can be configured easily, and accurate detection results of the temperature sensor 133 can be obtained even if the heater 131 has variations in size. In addition, it can be easily implemented by simply inserting the elastic body 3200 between the heater 131 and the wall portion 3131 c located on the opposite side of the temperature sensor 133 .
The elastically deformable portion 3210 has a contact portion 3211 a that contacts the extending portion 3220 . As a result, the reaction force from the heater 131 can be distributed to the end portion 3212a on the insertion tip side and the contact portion 3211a, and a greater biasing force can be generated. In addition, fatigue characteristics of the elastically deforming portion 3210 can be enhanced.
The elastically deformable portion 3210 has a “V” shape, one end 3212a is the end on the insertion tip side, the other end 3211a is the contact portion 3211a, and the contact portion 3211a is the extended portion 3220. It is slidable along. As a result, the force generated when the elastic body 3200 is inserted between the heater 131 and the wall portion 3131c can be released by sliding.
The elastic body 3200 has a pressing portion 3230 for pushing the elastic body 3200 at the end portion 3212a of the extending portion 3220 opposite to the insertion tip end portion 3212a. The pressing portion 3230 may be configured by a bent portion that bends from the opposite end to the elastic deformation portion 3210 side. As a result, the elastic body 3200 can be easily pushed in, and the insertion of the elastic body 3200 into the heating portion 3013 can be easily performed.
In addition, in the invention of the elastic body in which only the function of urging the heater 131 toward the temperature sensor 133 is taken into consideration, the shape and structure of the heating cylinder, the presence or absence of other temperature sensors 2133 and 2134, and the electric connection portion 131a of the heater 131 The position and the like are not particularly limited.

As long as the elastic body can generate an urging force toward the temperature sensor, it may be, for example, as shown in FIG.
The elastic body 3300 has an elastic deformation portion 3310 as shown in FIG. 20(a). The elastic deformation portion 3310 includes a first side portion 3311, a second side portion 3312, a connecting portion 3313 connecting the first side portion 3311 and the second side portion 3312, and a connecting portion 3313 at the first side portion 3311. It has a first folded portion 3314 folded back from the opposite end 3311a and a second folded portion 3315 folded back from the end 3312a opposite to the connecting portion 3313 of the second side portion 3312 . In this case, the connecting portion 3313, the end portion 3311a of the first side portion 3311, and the end portion 3312a of the second side portion 3312 directly contact the heater and the case. The end portions 3311a and 3312a constitute contact portions.
