The hot air generator is built in and includes a blower 4 and a heating element 5 and the like. The outside air entering from the intake port 2 is heated by the hot air generator 6 and discharged from the exhaust port 2. Reference numeral 7 denotes a hose which is rotatably and detachably supported at one end by the exhaust port 2, has a bellows portion 8 which can be extended and contracted at the center, and a cylindrical connection tube 9 at the other end. Reference numeral 10 denotes a humidity sensor that detects a predetermined humidity value and stops or starts the operation of the hot air generator 6. The humidity sensor 10 is electrically connected to the hot air generator 6 via a lead wire 11 and is attached to and detached from the surface of the main body 1. Mounted freely. The humidity sensor 10 is used by being placed on a body to be dried. Reference numeral 12 denotes a timer with a switch for supplying power to the hot air generator 6 and the humidity sensor 10 for a predetermined time. 13
Is a bag-shaped drying mat made of a ventilation material having at one end a communication port 14 detachably attached to the connection tube 9. Hot air generated by the hot air generating device 6 is passed through the hose 7 from the surface thereof by an arrow. Release in the direction. A is a futon and B is a futon.

FIG. 20 is a diagram showing a state of use of the futon drying by another conventional futon dryer disclosed in Japanese Patent Application Laid-Open No. 5-68789. The same or corresponding parts as those in FIG. 19 are denoted by the same reference numerals. In FIG. 1, reference numeral 1 denotes a main body having an intake port 2 and an exhaust port 3A. A hot air generator 6 composed of a blower 4 and a heating element 5 warms the outside air entering from the intake port 2 and discharges it from the exhaust port 3A. Built-in to be. Reference numeral 7 denotes a hose having one end rotatably / detachably supported by the exhaust port 3A, an elastic bellows portion 8 at the center, and a cylindrical connecting tube 9 at the other end. 10 is a connecting cylinder 9
And is electrically connected to the hot air generator 6 via a reinforcing piano wire (not shown) or the like provided in the bellows portion 8 to detect a predetermined humidity value and determine the temperature. This is a humidity sensor that stops and starts the operation of the wind generator 6.

Next, the operation will be described. In order to use the futon dryer, a drying mat 13 is spread and spread between the futon A and the futon B in FIGS.
The bellows portion 8 of the hose 7 is extended, and the connection tube 9 is inserted into the communication port 14 of the drying mat 13. At this time, in FIG. 20, the humidity sensor 10 does not enter the inside of the communication port 14 in order to accurately catch the drying condition of each of the futons A and B. In FIG. 21, the humidity sensor 10 is removed from the main body 1 and placed on the outer surface of the quilt A.

In this state, the timer 12 with a switch is operated to operate the hot air generator 6. The hot air generator 6 forcibly injects and passes outside air from the intake port 2, converts the outside air into hot air, and enters the inside of the drying mat 13 through the communication port 14 through the exhaust port 3 </ b> A and the hose 7. The hot air is discharged while inflating the drying mat 13 at that pressure. The discharged hot air is
The surroundings are warmed while passing through the futons A and B, and are released into the room with moisture. After the start of operation, FIG. 19 and FIG.
At 0, each of the humidity sensors 10 detects the humidity value of the warm air from each of the futons A and B when the humidity reaches a predetermined humidity value set in advance, and detects the humidity value via a control unit (not shown). Then, the operation of the hot air generator 6 is stopped to complete the drying of the bedding.

[0006]

In such a conventional configuration, in FIG. 19, the humidity sensor 10 is detached from the main body 1 and placed on a suitable place on the outer surface of the futon A, and Measure humidity. For this reason, the humidity sensor 10 changes its placement location each time it is used, or is affected by a change in the indoor humidity, so that the drying time tends to vary. Furthermore, since the humidity sensor 10 and the main body 1 are connected by the lead wire 11, the humidity sensor 10 easily moves on the futon A when some external force is applied, for example, when the user accidentally gets caught with a foot or the like. In addition, there is a problem that the device 1 is likely to fall off, and the operation of attaching and detaching to and from the main body 1 is troublesome.

Further, in FIG. 20, since the humidity sensor 10 is provided on the outer surface of the connection tube 9 formed in a cylindrical shape, the set position of the humidity sensor 10 is not always fixed and is set between the futons A and B. It changes every time. In general, the ratio of the amount of moisture absorption between the bedding A and the bedding B depends on the material and weight of the bedding, but the ratio of the bedding A to the bedding B is about 4: 6. It is relatively heavy and easily absorbs sweat and the like, and bedding B which is surrounded by the floor surface or the futon A and is hard to release sweat etc. into the room. This is because the futon A is easy to release the sweat and the like that has absorbed moisture in contact with the bed. For this reason, when drying the futon, it is necessary to surely catch the drying state of the futon B. That is, if the position of the humidity sensor 10 is located on the side of the futon A, the humidity sensor 10 operates at the humidity of the futon A.
There was also a problem that the dried food was insufficiently dried.

FIG. 21 shows a dry weight change curve in a futon dryer due to a difference in the amount of moisture absorption in the same futon. The ordinate represents the weight of the futon, and the abscissa represents the operation time. The futon is a weight (5 kg) in a completely dry state (after drying the futon, the dry weight per hour is 30 g or less). From the top, a: large amount of moisture absorption (700 g of moisture absorption), b: medium amount of moisture absorption (500 g of moisture absorption), c: small amount of moisture absorption (30% moisture absorption)
0g). As is clear from the figure, it takes more time for the futon of "a: large amount of moisture absorption" to reach the predetermined futon weight than the futon of "c: small amount of moisture absorption". In particular, in products without the humidity sensor 10, the user is required to determine the degree of wetness and drying of the futon. There was also.

Further, in FIGS. 19 and 20, since there is no indication of the drying end time at the time of starting the operation, the user is concerned about when the drying will end. There was also a problem that.

FIG. 1 is a partially cutaway sectional view showing a use state of the futon dryer, FIG. 2 is a diagram showing a relationship between an insertion shape of a connection port of a hose and an exhaust port of a main body, FIG. 3 is a block diagram of FIG. FIG. 4 is a flowchart showing the operation of the control unit of the futon dryer. In the above drawings, the same or corresponding parts in FIGS. 19 and 20 showing the conventional example are denoted by the same reference numerals, and detailed description thereof will be omitted. Arrows in the figure indicate the flow of air.

Reference numeral 15 denotes a sheet-like drying mat which wraps the upper surface, ie, the sleeping surface, of the bedding B so as to be accommodated therein, and is formed at one end thereof with an openable and closable fastener (not shown).

A connection projection 27 is provided as a part of the non-circular shape of the connection port 18, and a connection recess is formed as a recess forming a non-circular shape on the exhaust port 3 </ b> B side corresponding to the connection projection 27. Is provided.

Therefore, when the connection port 18 at one end of the hose 17 is attached to the exhaust port 3B, the connection projection 27 and the connection recess 28 are connected, and the vertical direction of the connection port 18 is determined. The vertical relationship of the exhaust pipe 20A on the other end side is also uniquely determined, and the first sensor 23 provided at the lower part of the exhaust pipe 20A can be configured to be always located at the lower side of the exhaust pipe 20A.

The exhaust pipe 20A has an outlet 21 for hot air at the upper part, and a first sensor 2 for detecting one or both of the temperature and the humidity by resistance at the lower part.
3 is formed. The first sensor 23 is connected to a reinforcing piano wire (not shown) wound around the bellows portion 19 or a connecting convex terminal 27A of a connecting convex portion 27 provided above the connection port 18 via a lead wire 26. It is connected.
When the connection port 18 is fitted into the exhaust port 3 having a concave shape substantially similar to the connection port 18 in the direction of the arrow in FIG. 2, the end face 18A of the connection port 18 comes into contact with the bottom surface 3Ba of the exhaust port 3B. Is fitted in a connection concave portion 28 which is a part of the connection port 18. At this time, the connection protrusion terminal 27A protruding from the connection protrusion 27 side of the end face 18A and electrically connected to the first sensor 23 is connected to the connection protrusion 28A provided on the connection recess 28 side of the bottom surface 3Ba. The hot air generator 6 and the first sensor 23 are electrically connected to each other. Even while the connection port 18 is being fitted into the exhaust port 3B, the connection port 18 does not have to worry about rotating.
There is no need to worry about damaging the connection convex terminal 27A when attaching and detaching.

As shown in FIG. 5, the shape of the exhaust pipe 20A is such that the lower part of the exhaust pipe 20A has a flat plate-like first sensor 23 so as to reliably catch the temperature and humidity values of the bedding B.
22A. As a result, since the detection portion 22A of the exhaust pipe 20A inserted from the communication port 16 is flat, the detection portion 22A can stably and reliably come into contact with the sleeping surface of the bedding B. Also, even if any external force is applied to the hose 17, the flat detecting portion 22A is difficult to move easily because the installation area is large, that is, the first sensor 2A.

Since the first sensor 23 is provided on the bottom surface side of the detection unit 22A, the warm air containing the moisture of the futon B flowing directly from the futon B without passing through the drying mat 15 is used as the first sensor. As a result, the temperature and humidity of the bedding B can be accurately detected.

Furthermore, since the support piece 25A having elasticity (see FIG. 1) is formed in the mat support portion 24A, the lower surface 16A of the communication port 16 of the drying mat 15 is securely held. Therefore, the mat 15 for drying is prevented from coming off.

Then each starts. At this time, in the course setting means 30, a preset temperature (65 ± 5 ° C.) is automatically set by the “cotton” key selected by the operation means 29 (step S04).

Next, a temperature command corresponding to the temperature (65 ± 5 ° C.) set by the course setting means 30 is sent to the futon temperature / humidity judging means 35 (step S1).
At this time, the measurement data of the bedding B from the first sensor 23 is also sent to the bedding temperature / humidity measuring means 34, converted into a temperature and sent to the bedding temperature / humidity determining means 35.

The futon temperature / humidity judging means 35 for judging whether or not the temperature of the bedding B is within the set temperature range is determined based on the temperature (65 ± 5 ° C.) set by the course setting means 30. The measurement data (temperature) of the bedding B from the sensor 23 is determined to be within the range, and a command is sent to the hot air control means 31 (step S2).

The hot air control means 31 having input the temperature command

The temperature of the bed B is a predetermined temperature (65 ± 5).
° C), the warm air control means 31 outputs a stop command for energization to the heating amount control means 32 and the blowing amount control means 33 (step S4). Immediately, the heating amount control means 32 and the blowing amount control means 33 automatically stop and end (step S5).

According to the above results, the exhaust pipe 20A is inserted into the communication port 16 of the drying mat 15 provided between the bedding B and the bedding A, and the operating means 29 is operated to obtain the moisture absorption amount. The first sensor comes into contact with the large bed of futon B, and in order to accurately judge and respond to the drying situation, the futon drying, which often relies on intuition, can be performed automatically and reliably. it can.

Embodiment 2 FIG. Next, even in the case of the futon having a different amount of moisture absorption than in the first embodiment, the drying state of the futon in the initial stage is caught, and the drying time is predicted and displayed on the main body 1 so that the user can easily recognize the drying end time. An embodiment will be described with reference to FIGS.

In the figures, the same or corresponding parts as those in FIGS. 1 to 5 are denoted by the same reference numerals, and their description is omitted. In the figure, reference numeral 36 denotes an energization time determination unit which detects a temperature change value of the futon B during a predetermined time, receives a signal from the futon temperature / humidity determination unit 35 for calculating a change rate, and sends a signal to the hot air generator 4. The power supply time is determined, and a signal is transmitted to a display means 37 and a hot air control means 38 described later. Reference numeral 37 denotes a display unit comprising a display unit provided at a position above the outer surface of the main body 1 so as to be easily seen by a user.

Reference numeral 38 denotes a hot air control means, which receives a signal for controlling the power supply time to the hot air generator 4 from the power supply time determination means 36, and after a lapse of a predetermined time, the heating amount control means 32 and the air supply amount control means. Through 33, the power supply to the hot air generator 4 is automatically stopped. The hot air control means 38 also receives the signal from the bedding temperature / humidity determination means 35 described in the first embodiment, and has the same function. Note that the priority when the information from the futon temperature / humidity judging means 35 and the energizing time judging means 36 are both entered into the hot air control means 38 is, for example, that the temperature of the bedding B is within the indicated energizing time. Even if the set temperature (65 ± 5 ° C) is reached,
The set temperature (65 ± 5 ° C.) is maintained, and the information from the energization time determination unit 36 is prioritized. However, the temperature of the bedding B immediately before the operation stop time is equal to the set temperature (65
If the temperature is lower than (± 5 ℃), this set temperature (65 ± 5 ℃)
Since the operation time is extended so as to enter, the information from the futon temperature / humidity judging means 35 is prioritized. After the operation is started, the temperature of the bedding B is input several times to the energization time determination means 36 via the futon temperature / humidity determination means 35 and the energization time is corrected, so that a more accurate display can be obtained. The display is performed at 37.

Reference numeral 101 denotes a control unit, as shown in FIG. 6, a course setting means 30, a hot air control means 39, a heating amount control means 32, a blowing amount control means 33, a futon temperature / humidity measuring means 34, a futon temperature / humidity measuring means. It is composed of a humidity determination means 35 and an energization time determination means 36, and is processed by a microcomputer.

Next, the operation will be described with reference to FIGS. The case where the material of the futons A and B is “cotton” and the first sensor is a temperature detecting sensor will be described. Body 1, hose 17 and drying mat 15
Connection and step S0 are the same as those in the first embodiment, and thus the details are omitted.

The energization time judging means 36 uses the first sensor 23, the futon temperature / humidity measuring means 34, and the futon temperature information on how the temperature of the futon B has changed during a predetermined time at the start of operation. In response to the change value determined in advance from the humidity determination unit 35 (details will be described later), the information about the operation end is sent to the hot air control unit 38 and the display unit 37 (step S12). The display means 37 displays the operation time or the operation end time for the hot air generator 6 to inform the user (step S1).

A command is issued to automatically stop energization of the hot air generator 6, and the hot air generator 6 terminates drying (step S4,
Step S5).

Here, the energization time to the hot air generator 6 is
Although it greatly depends on the amount of moisture absorbed by each of the futons A and B, the futon B within several minutes from the start of operation obtained from the experiment

Further, the energizing time to the hot air generator 6 and the display means 37
Is determined.

FIGS. 8 and 9 show the mattress B having an absolute weight of 5 kg.
Is a drying change curve of each of the temperature X and the relative humidity Y in the case of “Amount of moisture absorption (large)” in which 700 g of moisture is absorbed.
FIGS. 10 and 11 show that the bedding B having an absolute weight of 5 kg is 400
6 is a drying change curve of each of the temperature X and the relative humidity Y in the case of “moisture absorption (medium)” in which g of moisture has been absorbed. Figure 12
13 is a drying change curve of each of the temperature X and the relative humidity Y when the bedding B having an absolute weight of 5 kg absorbs 200 g of moisture and has a “moisture absorption (small)”. Figures 8, 10, and 12

9, 11, and 13, the vertical axis indicates the relative humidity Y (%), and the horizontal axis indicates the drying time T (minute). In addition,
The vertical axis of the temperature X is set such that the temperature increases downward.

As is apparent from the temperature change curves shown in the figures, the bed futon B at the initial operation time of 2 to 3 minutes was used.
Are different from each other, and the angles are compared as follows: “moisture absorption (large)” θt1 <“moisture absorption (medium)” θt2
<“Moisture absorption (small)” θt3. In addition, comparing the figures, the drying change curve of the humidity of the futon B is opposite to the drying change curve of the temperature because the same downward curve is obtained even though the temperature axis direction is reversed. The inclination is a gradient, and the humidity drop angle (θh) is compared as “moisture absorption (large)” θh1> “moisture absorption (medium)” θh2> “moisture absorption (small)” θh3.

Based on the above data, the amount of moisture absorption of the bedding B is subdivided, and the temperature rise angle (θt) and the temperature decrease angle (θh) and the respective drying times are obtained.
t, θh) is stored in the memory of the microcomputer, and the stored data is compared with the measured data. Then, the futon temperature / humidity judging means 35 determines whether the moisture absorption amount is close to large, medium, or small. How much temperature you need to raise,
It is possible to accurately determine how much dehumidification is required, and the like. The energization time determination means 36 determines the required operation time required for dehumidification at the start of operation and displays the result on the display means 37. Can be.

[Table 1]

The futon temperature / humidity judging means 39 sends data to the hot air volume control means 44 and the energizing time judging means 36 so as to automatically change and manage the temperature / humidity of the futon B based on the outside air temperature / humidity. Is sent.

Reference numeral 102 denotes a control unit, as shown in FIG. 14, a course setting unit 43, a hot air amount control unit 44, a heating amount control unit 32, a blowing amount control unit 33, a futon temperature / humidity measuring unit 34, a futon temperature / humidity measuring unit. Humidity determining means 39, energizing time determining means 36, outside temperature / humidity measuring means 41,
It is composed of humidity judgment means 42 and is processed by a microcomputer.

Next, the operation will be described with reference to the drawings. However, the material of the futons A and B is “cotton”, the first and second sensors 23 and 40 are each for temperature detection, and the outside air temperature is 20 ° C. First, in step S16,
The "cotton" key also serving as a start of operation in the operation means 29 is manually started (steps S160 and S16).
1) Then, the hot air generator 6 starts. At the same time, the first sensor 23 for measuring the temperature of the bedding and the second sensor 40 for measuring the outside air temperature also start the measurement (steps S162 and S164), and the respective data are transferred to the bedding temperature / humidity measuring means. 34, the bedding temperature / humidity judging means 39, the outside temperature / humidity measuring means 41, and the course setting means 43 via the outside temperature / humidity judging means 42 (Step S163, Step S165).

The course setting means 43 uses the data from the outside temperature / humidity judging means 42, which has judged that the outside air is 20 ° C., so that the temperature of the bedding B becomes 60 ° C. to 65 ° C. (step S).
17) A command is sent to the futon temperature / humidity judging means 39. The bedding temperature / humidity determining means 39 determines whether the data from the bedding temperature / humidity measuring means 34 is higher or lower than the data from the course setting means 43, and issues a command to the hot air volume control means 44. (Step S18). The hot air volume control means 44 adjusts the temperature of the bedding B to 60 ° C. to 65 ° C.
The operation of the hot air generator 6 is controlled (step S19) by instructing the heating amount control means 32 and the blowing amount control means 33 so that

Thereafter, the temperature of the bedding B is reduced to 60
When the temperature reaches ℃ to 65 ° C. (step S20), the futon temperature / humidity judging means 39 sends a command for instructing the hot air generator 6 to stop (step S4). That is, the process ends (step S5). Note that the priorities of the energization time determination unit 36 and the futon temperature / humidity determination unit 39 are the same as in the second embodiment, and a description thereof will be omitted.

As described above, with the change of the temperature or humidity of the outside air, that is, the seasonal change, the drying condition or time of the futon is changed, and the drying temperature is set high when the temperature is cold and low when the temperature is warm. Drying can be performed.

Embodiment 4 FIG. In the first embodiment, the exhaust pipe 20A is provided with the mat support portion 24A and the drying mat 1A is provided.
5 can be held, but as shown in FIG.
When the whole A is surrounded by the drying mat 15, the mat supporting portion 24A is not necessarily required. Therefore, an embodiment of the exhaust cylinder 20B in which the mat support portion 24A is not formed will be described with reference to FIG.

As shown in FIG. 16, the shape of the exhaust pipe 20B in the fourth embodiment is such that the lower part of the exhaust pipe 20B is a first flat plate in order to surely catch the temperature and humidity values of the bedding B. The detection unit 22B having the sensor 23 was used. As a result, the detection section 22B of the exhaust pipe 20B inserted from the communication port 16 is flat, so that the futon B
Can be in contact with the sleeping surface. Also, even if any external force is applied to the hose 17, the flat detection unit 22
Since B has a large installation area, it is difficult to move easily. That is, the first sensor 23 does not separate from the bed surface of the bed B and can keep catching the temperature of the bed surface of the bed B in a stable state. .

Embodiment 5 FIG. In the exhaust pipe A of the first embodiment, the first sensor is in direct contact with the bedding B without the intermediation of the drying mat 15, but the bedding B is more positively around the first sensor 23. An embodiment in which warm air flows from the air will be described with reference to FIG. 17A and 17B, similarly to FIG. 5, a mat support portion 24B as a cutout portion having a predetermined gap is formed in the exhaust pipe 20C between the flat plate-shaped detection portion 22C provided at the lower portion and the outlet 21 provided at the upper portion. The lower surface 16A of the communication port 16 at one end of the drying mat 15, which is formed in a bag-like shape with the upper surface made of a non-breathable material and the lower surface made of a breathable material, is formed to have elasticity in the mat support portion 24B. Since the holding piece 25B is sandwiched between the supporting pieces 25B, there is no fear that the drying mat 15 comes off as in the first embodiment.

For this reason, the detecting section 22A is provided with the drying mat 1
5 Not directly inside, but in direct contact with mattress B. Since the first sensor 23 is provided on the bottom surface side of the detection unit 22C, the warm air containing the moisture of the bedding B flowing directly from the bedding B without the intermediation of the drying mat 15 is used as the first sensor. 23.

Then, an air passage 45 formed in the detecting portion 22C around the first sensor 23 is formed,
A hollow space 46 connected to the air passage 45 is formed in the detection unit 22C, and a communication port 47 connected to the outlet 21 is formed on the inner wall 21A side of the outlet 21 of the space 46. And this communication port 47 is
A bypass passage which is inclined toward the outlet 21 and communicates with the air passage 45 through the space 46 and the outlet 21 is formed.

As described above, in normal use, the warm air generated by the warm air generator 6 enters the drying mat 15 through the outlet 21, but the outside air near the air passage 45 is
According to the principle of spraying, the temperature and humidity of the bedding B are reliably transmitted to the first sensor 23 while passing around the first sensor 23 from the air passage port 45, and the detecting unit 22C
The air enters the outlet 21 from the communication port 47 via the space 46 therein.

Therefore, not only the warm air from the bedding directly blows on the first sensor 23 but also the first air force is generated by the suction force using the flow force of the hot air generated by the hot air generator 6. In the fifth embodiment, in which warm air from the bedding flows around the sensor 23, the temperature and humidity of the bedding can be detected more accurately than in the fourth embodiment.

Further, in the fifth embodiment, even if the drying mat 15 is erroneously crushed during use, an abnormality is quickly caught and the safety of the main body is ensured.

That is, if the drying mat 15 is erroneously crushed in the fifth embodiment, the opening area of the drying mat 15 is reduced, the warm air is trapped, and the temperature of the drying mat 15 is abnormally high.
The internal pressure of 5 is increased. For this reason, the warm air flows backward from the normal state and enters through the communication port 47, and the warm air directly blows on the first sensor 23, rapidly raising the temperature of the first sensor 23 and from the air passage port 45. Discharged. As a result, the first sensor 23 transmits the abnormal high temperature information of the hot air to the futon temperature / humidity judging means 39 and outputs the information to the hot air generator 6.
The safety of the main body 1 can be ensured by stopping the operation of or by operating only the blower 4.

Embodiment 6 FIG. By the way, the above Examples 1 to
In 5, the outer shape of the connection port 18 and the concave shape of the exhaust port 3B are not limited to those shown in FIG. 2, but may be a non-circular shape such as an egg shape as shown in FIG. If the electrical connection mechanism is provided on the protruding portion when it is not circular as in the first embodiment, there is an effect that the protruding portion can be effectively used.

Further, in the sixth embodiment, the connection recess 28
Since the terminal 28B on the side is a protruding connection terminal and the terminal 27B on the connection protruding portion side is a connection concave terminal, even when the connection port 18 is not the exhaust port 3B, both the terminals 27 and 28 are externally connected. In this embodiment, there is no effect of damaging the terminal due to bumping, which is not provided in the first embodiment.

[0075]

Since the present invention is configured as described above, it has the following effects.

Since the wetness of the bedding which absorbs more moisture than the bedding is detected by the sensor, the drying of the bedding can be performed automatically and reliably.

Further, since the sensor is provided on the detection section in the form of a flat plate, the sensor can be reliably brought into contact with the bedding, and the wetness of the bedding can be detected in a stable state.

Further, at the start of the drying of the futon, the degree of wetness of the futon is detected by the sensor and the end of the drying is predicted, so that the end of the drying can be displayed on the main body in advance.

Further, by providing a sensor for detecting a change in the temperature or humidity of the outside air, the degree of drying of the futon can be changed, for example, in accordance with a change in the season.

Further, since the drying mat is held in the notch, the sensor for detecting the degree of drying of the futon is not located in the drying mat, but can be directly in contact with the bedding to detect the degree of wetness. it can.

In addition, when the drying mat is abnormal, a communication port is provided so that the hot air hits the sensor for detecting the degree of drying of the futon. Can be.
