Description

  The present invention relates to drying, warming, and dehumidification of bedding, and in particular, when drying bedding at a high hot air temperature, a person who accidentally sleeps on bedding is not burned at a low temperature. It is.

  Known beddings configured to feed warm air and cold air into this type of mattress have a structure as shown in FIGS. 5 and 6. That is, the quilt main body 101 is composed of an upper fabric 103a and a lower fabric 103b in which a batting 102 is integrated with a front fabric by quilting or the like, a porous hard layer 104 made of a material harder than the batting 102, and a hard layer 104 thereof. An air bag 105 for wrapping the layer 104 and for passing warm air or cold air is inserted into the mattress main body 101, and the mattress main body 101 is connected to the mattress main body 101 from the futon dryer 106 through a hose 107. Then, warm air 108 is supplied to warm the futon main body 101 (see, for example, Patent Document 1).

JP-A-8-84642

  In the above prior art, the quilt main body 101 configured to send warm air and cold air to the quilt main body 101 has a porous air-permeable hard layer 104 inserted therein, so that a person lays it. Since a space having air permeability can be secured even when sleeping on the futon main body 101, the futon main body 101 can be warmed by continuously sending warm air during sleep. In order to warm a user sleeping on such a mattress body 101, if the temperature of the mattress body 101 surface is kept warmer than the body temperature (about 36 degrees), there is a risk of low-temperature burns. It was necessary to be at temperature.

  On the other hand, when used as a dryer for drying the mattress main body 101, it is necessary to increase the drying efficiency of the mattress main body 101 and raise the hot air temperature to about 50 degrees or more in order to kill mites and the like.

  In order to make both usages compatible, a means of changing the hot air temperature depending on the usage, for example, a switch is provided in the futon dryer 106, etc., to switch between the hot air temperature at bedtime and the hot air temperature at futon drying. However, there is a risk that if the user goes to bed while warm air is blown on the futon main body 101 and the user sleeps while the futon is dry, there is a risk of low-temperature burns.

  The present invention has been made in order to solve the above-mentioned problems. In Claim 1, a quilt main body covered with a breathable fabric, and a breathable space provided in the quilt main body. A material unit, a ventilation bag provided on the lower side or the upper side of the space material unit and having an opening on a part of the side surface, the air bag formed of a poorly breathable material, and communicates with the space material unit and the ventilation bag. A connecting pipe provided in such a manner, hot air supplying means for blowing warm air or cold air to the space material unit and the ventilation bag through the connecting pipe, and control for controlling the temperature of the hot air supplied by the hot air supplying means And a pressure sensor for detecting the air blowing pressure of the hot air supply means, and the controller controls the temperature of the hot air blown by the hot air supply means by a signal from the pressure sensor.

  According to the second aspect of the present invention, a changeover switch for inputting to the control unit is provided, and the hot air temperature of the hot air supply means can be changed by switching to at least the hot air mode, the futon drying mode, and the air blowing mode by the changeover switch. Is.

  Further, according to the third aspect, the amount of hot or cold air blown to the ventilation bag is made larger than the amount of air blown to the space material unit.

  Since the bedding with a pressure detection function of the present invention is configured as described above, the surface temperature of the cloth of the mattress can be set to about 50 degrees by switching the changeover switch to the futon drying mode. For example, if a hanging futon is hung on the mattress, the mattress and the mattress can be dried and mites can be killed.

  By switching the changeover switch to the hot air mode, the surface temperature of the cloth of the mattress can be reduced to about 36 degrees, and even if the user keeps sending hot air at bedtime, there is a concern about low temperature burns. Can be without.

  Further, by switching the changeover switch to the air blowing mode, the hot air and moisture accumulated in the futon body can be discharged out of the futon body in a hot summer, and a comfortable sleeping environment can be created.

  In addition, when the user switches to bed-drying mode by switching the changeover switch and the user goes to bed on the bedside, the temperature of the hot air is automatically controlled by the pressure sensor signal so that low-temperature burns do not occur. In addition, since the quilt body can be kept warm, safe and comfortable bedding can be supplied.

  An embodiment of the present invention will be described below with reference to FIGS.

  FIG. 1 is a longitudinal sectional view of a bedding with a pressure detection function for explaining an embodiment of the present invention, FIG. 2 is a longitudinal sectional view of the main part, FIG. 3 is a plan view of the same, and FIG. 4 is a control of hot air supply means. It is a block diagram.

  In the figure, 1 is a mattress main body, 2 is a batting, 3 is a cloth-like material having air permeability, and is composed of an upper cloth 3a, a lower cloth 3b, and a side cloth 3c. The upper cloth 3a and the lower cloth 3b are The outer cover of the laid futon main body 1 is configured so that the batting 2 is integrated by quilting or the like and is covered with the side cloth 3c.

  6 is a space material, which is formed of a hard material having porous air permeability, and has such a hardness that the air permeability is not lost by being crushed by a person sleeping. It is what you have.

  Reference numeral 7 denotes a storage bag made of a cloth-like material having good air permeability. The space material 6 is stored in the storage bag 7 to form a space material unit 8. The space material unit 8 is provided in the mattress main body 1.

  Reference numeral 9 denotes a ventilation bag, which is made of a cloth-like material having poor air permeability, and is provided below the space material unit 8 in the mattress main body 1. Reference numeral 9 a denotes a warm air passage that flows through the ventilation bag 9. The ventilation bag 9 may be provided on the upper side of the space material unit 8.

  Reference numeral 10 denotes an opening, which is provided on a part of the side surface of the ventilating bag 9, and the air blown from here to the ventilating bag 9 has a breathability, for example, a mesh-like side fabric 3c having good breathability. It is discharged to the outside of the futon main body 1 through.

  11 is a connecting pipe, which is branched into a connecting pipe A11a for blowing air to the space material unit 8 in the quilt main body 1 and a connecting pipe B11b for blowing air to the ventilation bag 9, so that air can be blown to both. It is configured.

  Reference numeral 12 denotes a hot air supply means, a blower 13 driven by a motor (not shown), a blower casing 14 for guiding the wind generated by the blower 13, and a wind blown into the blower casing 14. A heater 15 that changes to wind, a pressure sensor 17 that detects the blowing pressure of the blower 13 provided at the tip of the connecting pipe 16 that is connected to the blowing casing 14, and a wind sensor that is provided downstream of the heater 15 The temperature sensor 18 includes a thermistor 18 that detects temperature, and a control unit 19 that controls the energization of the heater 15 and the blower 13 by inputting output signals of the thermistor 18 and the pressure sensor 17.

  A hose 20 lays the warm air supplied from the hot air supply means 12 and the cold air 23 to lay the space material unit 8 and the ventilation bag 9 of the futon main body 1. To connect.

  In the control block diagram of the hot air supply means 12 in FIG. 4, 21 is a changeover switch, 22 is an operation ON / OFF switch, which is provided in the hot air supply means 12 so that it can be operated by the user. A signal is input to the control unit 19 connected to a lead wire 19. The changeover switch 21 is a warm air mode for blowing warm air for warming the quilt body 1 at bedtime, a futon drying mode for blowing warm air for drying the futon, and only blowing air without energizing the heater 15. The air blowing mode to be set can be set, and the hot air temperature can be varied by switching the switch.

  The operation ON / OFF switch 22 is a switch for turning ON / OFF the operation of the hot air supply means 12.

  Next, the effect | action by the above structure is demonstrated.

  When drying the futon main body 1, when the changeover switch 21 is switched to the futon drying mode and the operation switch 22 is turned on, the control unit 19 energizes the heater 15 and energizes the blower 13, and the hot air flows through the hose 20. The air is blown to the connecting pipe 11 of the mattress main body 1 and is blown to the space material unit 8 and the ventilation bag 9 communicated by the connecting pipe 11.

  The air blown to the ventilation bag 9 is spread through a side fabric 3c having good ventilation characteristics through a mesh-like air permeability from an opening 10 provided in a part of the side surface of the ventilation bag 9. When the user is not on the quilt main body 1, the ventilation bag 9 is inflated and the air passage 9a is secured, so that the blowing pressure of the warm air does not increase that much. Accordingly, at this time, the pressure sensor 17 provided in the hot air supply means 12 detects a low pressure.

  The temperature of the warm air blown at this time is detected by the thermistor 18 and is controlled by the control unit 19 to control the energization of the heater 15 to be a constant temperature. The warm air blown to the space material unit 8 spreads over the space material 6 as a whole, and the upper fabric 3a portion is warmed to about 50 degrees by the warm air that is ventilated through the storage bag 7 and the upper fabric 3a to the upper surface of the futon main body 1. . As a result, if a quilt is placed on the quilt body 1, the quilt body 1 and the quilt can be dried at the same time, and mites can be killed by the temperature rise. When the operation switch 22 is turned ON, the blowing mode of the warm air blown to the mattress main body 1 is the same as that of the futon drying mode, but the temperature of the upper fabric 3a portion of the mattress main body 1 becomes about 36 degrees. Thus, the energization of the heater 15 is controlled by the control unit 19. Since the space material unit 8 is provided in the mattress main body 1, a warm air passage can be secured even when the user goes to bed on the mattress main body 1, and the storage bag 7 and the upper fabric 3a, Since the lower fabric 3b and the side fabric 3c are made of a breathable member, warm air can be ventilated into the mattress main body 1, and the user can keep warming the mattress main body 1 even at bedtime. it can. At this time, the ventilation bag 9 is crushed by the weight of the user and the air passage 9a cannot be secured, and the warm air that flows through this portion is concentrated in the space material unit 8, and the space material unit 8 relatively. However, since the air permeability does not change, the pressure of the warm air rises, and the pressure sensor 17 provided in the warm air supply means 12 detects a high pressure. In this way, it is possible to detect whether the user is riding on the quilt main body 1 or not by the detection output of the pressure sensor 17.

  Therefore, even if the user continues to heat the futon main body 1 with warm air at bedtime, there is no worry of low temperature burns because the temperature is low.

  When the changeover switch 21 is switched to the air blowing mode and the operation switch 22 is turned on, the blowing mode of the warm air blown to the mattress main body 1 is the same as described above, but the heater 15 is not energized. The cool air blown into the main body 1 allows the hot air or moisture remaining in the futon main body 1 to be discharged out of the futon in a hot summer or the like to sleep coolly.

  If the person accidentally goes to sleep on the quilt main body 1 during operation with the changeover switch 21 switched to the futon drying mode, the ventilation bag 9 is crushed by the weight of the user, thereby ventilating the ventilation bag 9. Since the passage 9a cannot be secured, the warm air that has flowed to the ventilation bag 9 side concentrates on the space material unit 8 side, so that the amount of air flowing to the space material unit 8 portion is relatively increased. At this time, since the air permeability of the storage bag 7 and the upper fabric 3a storing the space material 6 does not change, the blowing pressure blown from the warm air supply means 12 becomes high, and the pressure sensor 17 detects the pressure increase. The controller 19 controls the energization of the heater 15 so as to lower the hot air temperature while detecting the hot air temperature by the thermistor 18 based on the detection signal, so that the temperature of the upper fabric 3a of the mattress 1 is about 36 degrees. Control to be. In this case, since the space member 6 secures a ventilation path for the warm air by the space member 6, the warm air supply means 12 can continue to supply the warm air, and the upper fabric 3 a of the mattress main body 1 can be kept warm. However, because of the low temperature, there is no worry of low temperature burns.

  In order to reliably detect with the pressure sensor 17 that a person has got on the mattress main body 1 during the operation in the futon drying mode, an increase in the blowing pressure due to the load applied to the mattress main body 1 If the threshold value of the pressure sensor 17 is set so as not to detect the malfunction, malfunction can be prevented.

  Further, by allowing a large amount of warm air or cold air to be blown to the space material unit 8 and the ventilation bag 9 to flow toward the ventilation bag 9 side, the user goes to bed on the mattress main body 1 and the ventilation bag. When 9 is crushed, since the increase value of the blowing pressure due to the air passage 9a of the ventilation bag 9 being blocked increases, it can be easily detected by the pressure sensor 17, and malfunction can be prevented.

  Thus, by switching the changeover switch 21 to the futon drying mode, the surface temperature of the dough 3 of the mattress main body 1 can be set to about 50 degrees, and the mattress is hung on the mattress main body 1 or the like. The bed mattress 1 and the quilt can be dried and mites can be killed.

  Further, by switching the changeover switch 21 to the warm air mode, the surface temperature of the cloth 3 of the mattress 1 can be set to about 36 degrees, and even if the user keeps sending warm air at bedtime, the temperature is low. It can be assumed that there is no worry of burns.

  Further, by switching the changeover switch 21 to the air blowing mode, the hot air and moisture staying in the futon main body 1 can be discharged out of the futon main body 1 in a hot summer or the like, and a comfortable in-bed environment is created. Can do.

  Further, when the user switches to the futon drying mode by switching the changeover switch 21 and sleeps on the mattress main body 1, the hot air temperature is automatically controlled by the signal of the pressure sensor 17 to prevent low temperature burns. Since it is possible to continue to warm the futon main body 1 at a low temperature, a safe and comfortable bedding can be supplied.
