Similarly, the third direction is referred to as the front-back direction or the front-back direction, and one side of the third direction is referred to as the "back side" or the "rear side", and the other side is referred to as the "front side" or the "front side".
The device main body 1 and the hose body 3 will be explained below.

2. Apparatus Main Body As shown in FIGS. 5 and 6, the apparatus main body 1 includes a housing 11 having at least an intake port 11a and a discharge port 11b, and a housing 11 that blows air sucked in from the intake port 11a toward the discharge port 11b. It includes an air blowing section 12 and a heating section 13 that heats the air blown from the air blowing section 12.
In addition to the blower section 12 and the heating section 13, the device main body 1 includes, for example, a hose connection section 14 (see FIG. 2) that connects to one end 32 of the hose body 3, an operation section 15 for operating the drying device, and a blower section. 12 and the heating section 13, a support section 161 that supports the hose body 3 in the housed state, a power supply section that supplies power to the blower section 12, etc., and a winding around which a cord 179 is wound for connection to a commercial power supply. One or more of the attaching part 165 and the cover part 19 that covers the connection part of the hose body 3 may be provided, and here, the apparatus main body 1 including all of them will be described.
Note that the control section and the power supply section are integrated, and will be described as a circuit section 17 here. Further, the support portion 161 and the wrapping portion 165 are constituted by an integrated support wrapping member 16.

(1) Air blower The air blower 12 includes a blower fan and a drive motor. Here, the ventilation fan is constituted by a sirocco fan, and the drive motor is constituted by a brushless motor. As shown in FIGS. 8(a) and 8(c), the blower unit includes a blower-type blower unit 122 that integrally includes a sirocco fan (not shown) and a drive motor (not shown) in a casing 121, and A ventilation case 123 that accommodates the unit 122 is provided.

It has an exhaust port 121a on the 13 side. Note that the end wall 121b appearing in FIG. 8(c) is one end wall (left end wall) of the casing 121.

The blower case 123 has a shape corresponding to the blower unit 122 and is composed of a case body 124 and a case cover 125. The end wall 124a of the case body 124 faces (at least one) of the intake ports 11a of the housing 11, and as shown in FIG. , has a circular opening 124b. Case cover 125 faces the right end wall of casing 121 of blower unit 122 .

The air sucked in from the opening 124b of the end wall 124a of the case body 124 passes through the case cover 125 side along the peripheral wall 121c (see (c) in FIG. 8) inside the ventilation case 123, and is then sucked into the right end wall of the casing 121. It enters the casing 121 through the opening and is discharged toward the heating section 13 through the exhaust port 121a of the casing 121. As a result, the opening 124b of the case body 124 and the intake port of the casing 121 become far apart, and the noise from the ventilation unit 122 leaking to the outside of the ventilation section 12 is reduced between the opening (124b) of the ventilation case (123) and the intake port of the casing (121). This can be made smaller than when the air intake ports are placed opposite to each other.

As shown in FIG. 8C, the blower section 12 includes one or more absorbing members 126 between the casing 121 and the blower case 123 (case body 124) for absorbing vibrations of the drive motor. The absorbent member 126 is made of an elastic body such as sponge (polyurethane, polyester, glass wool, polyethylene terephthalate, polyolefin, silicone, rubber), for example. Note that the absorbing member 126 also functions as a support member that supports the ventilation unit 122 within the ventilation case 123.

In other words, as shown in FIG. 2(b), the rotation axis A1 of the blower section 12 is located approximately at the center of the apparatus main body 1 in the front and back directions, and the discharge port 11b of the apparatus main body 1 is located at the center (or approximately located on the back side from the center). Note that the exhaust port 123a of the ventilation case 123 is an exhaust port of the ventilation section 12, and is designated by the reference numeral 123a.

(2) Heating section The heating section 13 includes at least a heater 131, as shown in FIG. The heating section 13 here is disposed above the exhaust port 123a of the blower section 12 (on the discharge port 11b side of the device main body 1). The heating section 13 includes a heating cylinder 132 connected to the blow case 123 of the blower 12 in communication with the exhaust port 123a of the blower 12, and a heater 131 disposed inside the heating cylinder 132. . Note that the heating cylinder 132 is provided with a temperature sensor 133 that measures the temperature of the air heated by the heater 131, as shown in FIG. 8(b).

(3) Hose Connection Portion The hose connection portion 14 (see FIG. 2) includes a cylindrical portion 141 that fits onto one end portion 32 of the hose body 3, as shown in the enlarged view of FIG. 3(b). For the connection between the hose connection part 14 and the hose body 3, an engagement structure, a screw structure, an adhesive structure, etc. can be used. Here, a screw structure is used. Therefore, the inner peripheral surface of the cylindrical portion 141 is a thread (female thread) 141a, into which the thread 32a of the one end portion 32 of the hose body 3 is screwed. The hose connection part 14 is held on the housing 11 side using a cover part 19.
The hose connection portion 14 is composed of an annular body 143, as shown in FIGS. 5 and 6. The annular body 143 has the above-mentioned screw 141a on its inner peripheral surface, and also has a filter part 145 on the side of the blowing part 12 to prevent foreign matter from entering.

(4) Cover Part In addition to the function of protecting the hose body 3, the cover part 19 has a function of holding the annular body 143 of the hose connection part 14 in the housing 11, for example.
As shown in FIGS. 5 and 6, the cover portion 19 includes a cylindrical portion 191 extending in the vertical direction, an outer flange portion 193 extending radially outward from one end of the cylindrical portion 191, and a cylindrical portion 191 extending in the vertical direction. It is constituted by a cylindrical body 197 that integrally includes a stepped portion 195 between a portion 191 and an outer flange portion 193.
As shown in the enlarged view of FIG. 3(b), the cover part 19 has a cylindrical part 191 and a step part 195 inserted into the discharge port 11b of the housing 11 from the inside, and an outer flange part 193 that is inserted into the discharge port 11b of the housing 11. It is fixed to the casing 11 in a state where it comes into contact with the periphery of the discharge port 11b. The annular body 143 of the hose connection part 14 is disposed on the stepped part 195 of the cylindrical body 197 and is supported by the heating cylinder 132 of the heating part 13 from the inside of the housing 11 . In this way, since the stepped portion 195 (annular body 143) is located at the lower end of the cylindrical body 197 in the vertical direction, the total length of the hose body 3 can be reduced more than when the annular body is located at the upper end or in the middle of the cylindrical body 197, for example. You can make it longer.
As shown in FIG. 3B, the cylindrical portion 191 accommodates the one end 32 side of the hose body 3 (the other end side of the hose body 3 from the connection part with the discharge port 11b of the housing 11). This makes it possible to protect the one end 32 side of the hose body 3. In other words, the cylindrical portion 191 can also be said to be a hose accommodating portion that accommodates the one end 32 side of the hose body 3.

(5) Operation unit As shown in FIG. 2, the operation unit 15 controls, for example, turning the power on or off, selecting the hot air temperature, selecting the hot air discharge time, setting the timer, selecting the automatic mode, etc. An operation board 153 (see FIG. 6) is provided with an operation portion 151 (see FIG. 5) for performing the operation.

There is a fourth mode that warms the futon to a state warmer than room temperature when sleeping.

(6) Circuit section (6-1) Control section The control section 171 controls the blower section 12 (drive motor) and the heating section so that the hot air temperature, air volume, and operating time are set by the user's operation of the operation section 15. 13 (heater 131), control the blower section 12 and heating section 13 according to the automatic mode selected by the user, and stop the driving using the temperature sensor 133.
As shown in FIG. 9, the control unit 171 is composed of, for example, a CPU, a working RAM, a storage unit, a timer, etc., and is configured based on various setting data stored in the storage unit or when in automatic mode. controls the driving of the blower section 12 and the heating section 13, respectively, based on a computer program stored in the storage section.
As shown in FIG. 7, the control unit 171 includes an electronic component 172 that constitutes a CPU, a RAM, a storage unit, etc. on a circuit board 173. The circuit board 173 is disposed on the right side of the air blower 12 and on the front side of the rotation axis A1 of the air blower 12. Thereby, the space on the front side of the rotation axis A1 of the blower section 12 can be effectively utilized. Note that in FIG. 5 and the like, the electronic component 172 is shown as one block.

The control unit 171 controls the ON/OFF operation of the heating unit 13 based on the temperature detected by the temperature sensor 134 (see FIG. 7), so that the selected or set hot air temperature is achieved. .
Specifically, as shown in FIG. 10, when a predetermined set temperature is Te3, the control unit 171 starts driving the heating unit 13 when the temperature detected by the temperature sensor 133 of the heating unit 13 reaches Te4, which is higher than Te3. When the detected temperature reaches Te2, which is lower than Te3, the heating section 13 is driven, and when the time measured by the timer reaches the set time Ti1, the heating section 13 is stopped, and when the detected temperature reaches Te1, the blowing section 12 is activated. Stop driving.

When the fourth mode is selected in the automatic mode, the control unit 171 drives the heating unit 13 and the blowing unit 12 so that the set temperature Te3 is higher than the temperature detected by the temperature sensor 134 by a predetermined temperature.
That is, when the control unit 171 receives the fourth mode as the automatic mode through the operation unit 15, the control unit 171 performs a step of acquiring the detected temperature from the temperature sensor 134, and a step of setting the set temperature Te3 to be heated based on the detected temperature. A step of controlling the driving of the heating section 13 based on the set temperature Te3 is performed.
In an invention that focuses on the fourth mode, in a drying device that has a hose body whose other end is inserted into an object and is capable of executing a hot air mode in which hot air is discharged from the other end, the interior of the drying device is a heating section that heats the air taken in to generate the warm air; a temperature detection section (temperature sensor) that detects the temperature at the installation position; and a control section that controls the heating means based on the detected temperature. Equipped with.

To set the set temperature Te3, a table is stored in the storage unit that associates the heating temperature to be heated (difference between the set temperature and the detected temperature) and the detected temperature with respect to the detected temperature. This is performed by acquiring the heating temperature from the storage unit and adding the heating temperature acquired from the storage unit to the detected temperature. Note that when the room temperature is high (for example, in spring or autumn), the difference between the heating temperature and the room temperature is small, and when the room temperature is low (for example, in the winter), the difference between the heating temperature and the room temperature is large. They are each set so that
At this time, as shown in FIG. 7, the control unit 171 detects the temperature from a temperature sensor 134 provided outside the ventilation case 123 of the ventilation unit 12 and between the ventilation case 123 and the intake port 11a of the housing 11. Since this is obtained, the influence of heat generated from the electronic components 172, circuit board 173, etc. of the circuit section 17 can be reduced. Note that since the temperature sensor 134 mainly measures the temperature of the room, it can also be called a room temperature sensor.
In particular, by making the intake port 11a the intake port located on the opposite side in the vertical direction from the discharge port 11b (on the lower wall of the housing 11), the device main body 1 can be covered with a futon or the like during use. The bottom wall of the housing 11 is difficult to cover, and air having room temperature is sucked in through the intake port 11a. This makes it possible to accurately measure the room temperature, perform accurate heating in consideration of the room temperature, and improve comfort when getting into the futon for sleep.
When the operating time of the drying device is selected by the user, the control unit 171 starts a timer and causes the display portion 155 to display the elapsed time from the start of air blowing or the remaining operating time.

(6-2) Power supply unit The power supply unit receives power from a commercial power source via the cord 179 (see FIG. 6) and generates power to be supplied to the blower unit 12, heating unit 13, operation unit 15, control unit 171, etc. do.

A third embodiment will be described using FIGS. 14 and 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 components as in the first embodiment.
Note that the configuration of the control unit in the third embodiment is the same as the control unit 171 in the first embodiment (the fourth mode program is different from the first embodiment), but it is different from the first embodiment. Although not shown in the figure, the control unit of the third embodiment is designated by the reference numeral "2171" for differentiation.
Further, the position of the temperature sensor is changed from the position of the temperature sensor 134 in the first embodiment, and will be described as a temperature sensor 2134 in the third embodiment. As described later, the temperature measured by the temperature sensor 2134 is the temperature above the heater 131, but the measured temperature is associated with the temperature discharged from the nozzle body 33, and the temperature around the nozzle body 33 in the bedding is correlated with the temperature discharged from the nozzle body 33. Corresponds to temperature.

1. Control Unit When the fourth mode is selected in the automatic mode, the control unit 2171 has a plurality of types of target temperatures 2Te1, as shown in FIG. 14, and is determined based on the room temperature 2Te0 before heating.
Here, the target temperature 2Te1 when the room temperature 2Te0 is "2Te0a" is "2Te1a", the target temperature 2Te1 when the room temperature 2Te0 is "2Te0b" is "2Te1b", and the target temperature 2Te1 when the room temperature 2Te0 is "2Te0c" is "2Te1b". The target temperature 2Te1 is "2Te1c".
In addition, when it means a numerical value such as temperature, "" is attached.
The specific numerical relationship between the room temperature 2Te0 and the target temperature 2Te1 here is as shown in FIG. 14, as follows.
2Te0a<2Te0b<2Te0c<2Te1c<2Te1b<2Te1a

The control unit 2171 corresponds to the first step of discharging hot air at a first temperature of “2Te2” until the elapsed time 2Ti reaches the first time of “2Ti1” and the room temperature 2Te0 measured by the temperature sensor 2134. A second step of lowering the temperature until it reaches the target temperature 2Te1, and a third step of maintaining the target temperature 2Te1 lowered in the second step until the elapsed time 2Ti reaches a second time of "2Ti2".
In addition, in the second step, since the time taken to lower the temperature varies depending on the room temperature, the time of the second step is not constant and does not reach a predetermined time.
"1", "2", and "3" written along the horizontal axis in FIG. 14 indicate the first step, second step, and third step, respectively, when the room temperature 2Te0 is "2Te0b". Here, as described above, since the second step indicated by "2" changes depending on the room temperature, it does not take a constant time like the first step indicated by "1". In addition, the second time "2Ti2", which is the total operating time, is predetermined at a predetermined time (unless the user turns off the power at an arbitrary 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.

The process will be explained below using the flowchart shown in FIG.
The control unit 2171 starts when the user selects the fourth mode.
When the control unit 2171 starts, after clearing the room temperature 2Te0, the target temperature 2Te1, etc. to 0, and resetting the timer, etc., the control unit 2171 acquires the room temperature 2Te0 from the temperature sensor 2134 in several seconds to several tens of seconds at the most (S201), and the heating unit The heater 131 of No. 13 and the drive motor of the blower unit 122 are turned on (S202), and a timer is started (S203).
At this time, the temperature of the hot air discharged from the nozzle body 33 of the hose body 3 (with the heater ON) 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 obtained 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 decreases from the temperature 2Te2 of the warm air discharged from the nozzle 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 regions, and a target temperature 2Te1 is set for each temperature region.
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 if the room temperature 2Te0 measured by the temperature sensor 2134 is 13 [°C] or more, the target temperature 2Te1 is a temperature in the range of 40 [°C] or more and 50 [°C] or less (for example, 45 [°C]). is set to .

When the temperature 2Te measured by the temperature sensor 2134 falls to the target temperature 2Te1 ("Yes" in S207), the control unit 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 to perform feedback control (S208).
When the elapsed time 2Ti of the timer reaches the second time "2Ti2"("Yes" in S204), the control unit 2171 turns off the drive motor (S210) and ends the process.
Note that 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 period of time has elapsed after the heater 131 is turned OFF.
When the control unit 2171 receives an operation from the user to end the operation in the fourth mode, the control unit 2171 interrupts and ends the process.

As mentioned above, after heating to a temperature higher than the target temperature 2Te1 ("2Te2"), in order to maintain the target temperature 2Te1 while cooling naturally, the heater 131 is turned off and the drive motor is operated at approximately the maximum output value. It is sufficient to operate with the power consumption suppressed to 20 to 30%, and the noise from the blower section 1012 can be reduced while suppressing power consumption related to driving the heater 131 and motor. Furthermore, temperature unevenness within 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 considering the room temperature compared to the target bed temperature (range of 31 [℃] or higher and 35 [℃] or lower) that makes the sleeper feel comfortable when they are inside the bedding. It becomes. 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 more. This makes it possible to provide the above-mentioned target bed temperature that is considered comfortable for the user, regardless of the season (time) of use, except for summer.

The drying device of the third embodiment described here is a drying device that executes a mode in which bedding is heated before going to bed and kept warm at a target temperature.
As such a drying device, there is, for example, one disclosed in Japanese Patent Application Laid-Open No. 5-345098. However, this drying device dries the futon at a high temperature even when the room temperature is high, such as in the summer, so it takes a long time to lower (finish) the futon temperature, which tends to increase electricity costs. In addition, since the room temperature is detected after the futon is dry, the temperature sensor installed near the heater cannot accurately detect the room temperature due to the high temperature of the atmosphere around the futon. There is also a risk that the futon cannot be kept within a comfortable temperature range (because the optimal air blowing time cannot be set).
The drying device according to the third embodiment determines a plurality of types of target temperatures based on the room temperature before heating when executing a mode in which bedding is heated before going to bed and kept warm at a target temperature. As a result, when used in a similar temperature environment, the temperature of the bedding is kept at a nearly constant temperature, and regardless of the season or time, variations in the temperature of the items to be dried are reduced depending on the room temperature at the time of use. can.
The drying device according to the third embodiment that performs such control is an invention that can reduce variations in the temperature of the dried material (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 entire device has a thin box shape. As shown in FIG. 16(a), the temperature sensor 2134 has a detection portion 2134a at a position 10 mm away from the upper surface of the heater 131 (in the direction in which the air is blown) (which is "L1" in the figure). The heater 131 is arranged parallel to the upper surface 131b of the heater 131. Note that the detection portion 2134a is preferably located within a range of 8 to 15 [mm] from the top surface of the heater 131 from the viewpoint of reliability of the measured temperature.
Further, as shown in FIG. 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). has been done. Note that the detection portion 2134a is preferably located within a range of 15 to 25 [mm] from the inner surface of the heating cylinder 132 from the viewpoint of reliability of the measured temperature.
As a result, even though the temperature sensor 2134 is disposed above the heater 131 and measures the temperature of the air heated by the heater 131, as shown in Table 1, air is blown out from the nozzle body 33. There is a good correlation between the temperature of the hot air (which is the "nozzle outlet temperature" in the table) and the temperature measured by the temperature sensor 2134 (which is the "thermistor temperature" in the table). In other words, variations in the temperature measured by the temperature sensor 2134 with respect to the temperature at the nozzle body 33 can be reduced.

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, even though the target temperature is managed based on the temperature measured by the temperature sensor 2134 disposed near the heater 131, the actual temperature inside the bedding can be managed with high accuracy.

Here, the heating cylinder 132 of the heating section 13 is provided with a rib wall 132a that is spaced inward from the inner wall of the heating cylinder 132 and parallel to the direction in which the hot air passes, and the temperature sensor 2134 is mounted along the rib wall 132a. Fixed. Thereby, the position of the detection portion 2134a of the temperature sensor 2134 remains fixed, allowing stable temperature measurement. Further, since the detection portion 2134a 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 inside the heating cylinder 132 and the temperature of the heater 131 is indirectly measured by the temperature sensor 133. However, the heating cylinder includes an elastic body that biases the heater toward the temperature sensor. You can.
Conventionally, since the heaters used vary in size, the distance between the heater in the heating cylinder and the temperature sensor is not constant, and there has been a problem that the temperature of the heater cannot be detected accurately. Note that because the temperature of the heater (applied power) is adjusted based on the detection result of the temperature sensor, in the conventional method, the temperature of the hot air blown out from the heating section was unstable.
In the fourth embodiment, by providing the elastic body, the distance between the heater and the temperature sensor is constant even if the heater size varies, and the temperature of the heater can be accurately measured by the temperature sensor.

1. Overall The fourth embodiment will be described mainly using FIGS. 17 to 19.
Note that the fourth embodiment differs from the first embodiment in the heating section 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. 17 to 19.
The heating unit 3013 includes a heating cylinder 3130, a heater 131 disposed inside the heating cylinder 3130, a temperature sensor 133 provided on the outer surface of the heating cylinder 3130, and biases the heater 131 toward the temperature sensor 133. and an elastic body 3200.
Note that the heating cylinder 3130 constitutes a case that houses the heater 131, and a temperature sensor 133 is attached to the case. Further, although one elastic body 3200 is used here, a plurality of elastic bodies may be used.
The heater 131 is a so-called ceramic heater (PTC heater) in which a heating element (PTC element) is sandwiched between heat sinks and an electrode sheet is bonded to the heat sink. The heater 131 has a rectangular parallelepiped shape with a low (thin) height (thickness). Here, the temperature sensor 133 is provided on one end surface 131c which is rectangular in plan view and perpendicular to the longitudinal direction (this end surface is referred to as the first end surface), and the temperature sensor 133 is provided on the other end surface (this end surface is referred to as the first end surface) orthogonal to the longitudinal direction. An elastic body 3200 is provided on the side (which is referred to as the second end surface) 131d.
Note that the end faces of the heater 131 in the lateral direction may be the first end face and the second end face, or the heater 131 may have a rectangular shape in plan view. That is, the first end surface and the second end surface may be end surfaces located 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 the case (partition wall portion 3131k, which will be described later) that is 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 (partition wall portion 3131k), and this correlation has been determined in advance through a test or the like. The temperature sensor 133 is, for example, a bimetal type.

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

The lower cylinder body 3131 mainly has the function of accommodating 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 a plan view, and the inner peripheral surface shape of the lower cylinder 3131 has a rectangular shape in a cross section.
A temperature sensor 133 is attached to a wall portion 3131a of the lower cylinder 3131 facing the first end surface 131c of the heater 131. The temperature sensor 133 here is fixed while being inserted into 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. Thereby, variations in temperature detection accuracy between individual drying apparatuses can be reduced.

A support portion 3131d that supports the elastic body 3200 is provided on the inner surface of a 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 to distinguish it from an upper support portion 3132c 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 on the lower cylinder body 3131. The installation direction of the heater 131 here 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. Note that the insertion direction of the elastic body 3200 is also the same.
The lower support portion 3131d supports the elastic body 3200 from the opposite side to the insertion direction of the elastic body 3200. Here, the lower support part 3131d supports from the blower part 12 side. In addition, in the direction in which the cylinder axis of the heating cylinder 3130 extends, the blowing section 12 side may be referred to as the lower side, and the hose body 3 side may be referred to as the upper side.
As shown in FIG. 18A, the lower support portion 3131d includes one or more protruding portions 3131e that protrude toward the heater 131 from the inner surface of the wall portion 3131c. The protruding portions 3131e have, for example, a plate shape, and there are two of them.

The inner surface of the wall portion 3131c is provided to prevent the elastic body 3200 from moving in a direction perpendicular 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). A regulating section 3131f is provided for regulating. Here, the regulating portions 3131f are provided on both sides of the elastic body 3200. The restricting portion 3131f is constituted by a pair of rib portions 3131g extending on both sides of the elastic body 3200 in the insertion direction. The lower ends of the pair of rib portions 3131g are connected to the protruding portion 3131e of the lower support portion 3131d, as shown in FIG. 18(a). The protruding portion 3131e is reinforced by the rib portion 3131g. Note that the pair of rib portions 3131g also serve as guide portions that guide insertion of the elastic body 3200.

The lower cylinder 3131 has a heater support portion 3131h that protrudes inward to support the heater 131 from below, and a groove 3131j for the electrical connection portion 131a of the heater 131. The lower cylinder 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. To be precise, the heater 131 is housed in a space formed by the partition wall 3131k and other walls except the wall 3131a. In other words, the part of the case that accommodates the heater 131 and where the temperature sensor 133 is provided is the partition wall part 3131k.
A thermal fuse 3135 is provided on the upper cylinder 3132 side of the partition wall portion 3131k. Thermal fuse 3135 operates to cut off the current when the temperature of heater 131 rises excessively. Note that the partition wall portion 3131k may be configured as a wall portion of the lower cylinder, and in this case, this can be implemented by providing the thermal fuse 3135 on the outside of the wall portion.

An elastic body 3200 is supported from the opposite side (upper side) to the lower support part 3131d on the inner surface of a wall part 3132b that constitutes the upper cylinder body 3132 and is located above the wall part 3131c of the lower cylinder body 3131. 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 contacts the bent portion 3230 of the elastic body 3200 from the insertion direction of the elastic body 3200. The upper support portion 3132c is constituted by a rib portion 3132d that protrudes inward from a midpoint of an imaginary line extending from the pair of rib portions 3131g and extends in the insertion direction. Thereby, the elastic body 3200 can be prevented from coming out from between the heater 131 and the lower cylinder 3131 in the direction opposite to the insertion direction, and the heater 131 can be biased toward the temperature sensor 133 for a long period of time.

The upper cylinder 3132 has a heater support portion 3132f that supports the heater 131 from above. The heater support portion 3132f is constituted by a rib that protrudes inward from the inner circumferential surface and extends along the insertion direction of the heater 131.
The upper cylinder 3132 has a mounting portion 3132g for mounting the cover portion 19, as shown in FIG. The attachment portion 3132g is constituted by an outer flange that projects radially outward from the upper end edge. The mounting portion 3132g of the upper cylinder 3132 has grooves for fixedly supporting the temperature sensors 2133 and 2134. Note that the temperature sensors 2133 and 2134 are, for example, thermistors, the temperature sensor 2133 is for detecting abnormal temperature of the heater 131, and the temperature sensor 2134 is for controlling the temperature of hot air.
The upper cylinder 3132 has a rib wall 3132k on the inside of a 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 3132j 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 a wall portion 3131c facing the wall portion 3131a (partition wall portion 3131k) where the temperature sensor 133 is disposed, so as to move the heater 131 toward the wall portion 3131a side. to energize. 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 is in contact with the wall 3131a (partition wall 3131k), and the cover surface of the temperature sensor 133 is placed at a fixed position relative to the wall 3131a (partition wall 3131k). Even if the size of the heater 131 varies, the distance between the temperature sensor 133 and the first end surface 132c of the heater 131 is constant. Note that 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.

The following description will mainly be made using FIG. 18(b).
The elastic body 3200 is formed by, for example, bending or bending a thin metal plate, and has a so-called leaf spring structure. The elastic body 3200 has at least an elastically deformable portion 3210 disposed between the heater 131 and the wall portion 3131c.
The elastic deformation portion 3210 elastically deforms in response to a change in the distance between the heater 131 and the wall portion 3131c, and generates a biasing force in a direction that increases the distance between the heater 131 and the wall portion 3131c.
The elastic deformation 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 opening side of the V-shape is placed on a plane) is configured to be 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 surface 131d of the heater 131), and the connecting portion 3213 and the opposite end 3211a of the first side portion 3211 contact each other. The connecting portion 3213 and the opposite end 3212a of the second side portion 3212 are connected directly or indirectly (in this case, indirectly through an extending portion 3220, which will be described later) to the heater 131 and the other side of the wall portion 3131c ( Here, it comes into contact with the wall portion 3131c). Note that the end portion 3211a of the first side portion 3211 constitutes a contact portion because it indirectly or directly contacts the heater 131 or the wall portion 3131c. The reference numeral 3211a is also used for this contact portion.

When the distance between the heater 131 and the wall 3131c is small, the elastically deformable portion 3210 may cause the distance between the end 3211a of the first side portion 3211 and the end 3212a of the second side portion 3212 to become large, or 3211 and/or the second side portion 3212 is elastically deformed, such as by curving so as to bulge in the thickness direction. An urging force is generated by the restoring force of this elastic deformation.
The end 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 moves smoothly, and the end portion 3211a can easily move in the distance direction relative to the end portion 3212a on the second side portion 3212 side. In particular, by providing the extending portion 3220 described below, the end portion 3211a can slide along the extending portion 3220, and can move more smoothly.

The elastic body 3200 has an extending portion 3220 extending from the end 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 extending portion 3220 here extends along the insertion direction. The extending portion 3220 extends parallel to the insertion direction, that is, in a straight line. Note that the end portion 3212a of the second side portion 3212 is also a connecting portion between the second side portion 3212 and the extension portion 3220, and the connecting portion is also designated as “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 toward the first side portion 3211 side. Thereby, the elastic body 3200 can be easily inserted by inserting it from the connecting portion 3212a side.
The extending portion 3220 extends upward longer than the folded portion 3214. Thereby, when inserting the elastic body 3200, the end 3211a of the first side portion 3211 can be prevented from being caught on the wall 3131c or the second end surface 131d of the heater 131, and the elastic body 3200 can be inserted smoothly. Further, during insertion, 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. Furthermore, even when the elastic deformation section 3210 is elastically deformed during insertion, the end 3211a of the first side portion 3211 comes into contact with the extension section 3220 and can move along the extension section 3220, allowing the elastic body 3200 to move smoothly. Can be inserted.

The elastic body 3200 has a bent portion 3230 that is bent toward the side where the elastic deformation portion 3210 is present, at the end of the extending portion 3220 on the side opposite to the connecting portion 3212a. As a result, when inserting the elastic body 3200, since the bent portion 3230 is bent to the opposite side to the wall portion 3131c, the bent portion 3230 does not come into contact with the wall portion 3131c, and the elastic body 3200 can be inserted smoothly. can. Moreover, when inserting the elastic body 3200, the elastic body 3200 can be easily inserted by pushing in the bent portion 3230.
The bent portion 3230 is located above the upper surface 131e of the heater 131, as shown in FIG. 17(b). This prevents the bent portion 3230 from coming into contact with the heater 131 when the elastic body 3200 is inserted. Further, when removing the elastic body 3200, it can be easily done by using the bent portion 3230.

3. About the elastic body Although the elastic body 3200 had a V-shaped elastic deformation part 3210, an extension part 3220, and a bent part 3230, the elastic body may have the following configuration.
