Abstract

PURPOSE:To provide electric bedding which is equipped with a drying function and which does not require the trouble of laying an air blowing mat when drying a quilt for use in bed, while ensuring the suction of air. CONSTITUTION:A bedding portion 7 which is installed on a bed mattress 23 having an air passage 14 therein and blowout holes each formed through the surface thereof and communicated with the air passage, and a heater unit 8 integrated into the bedding portion 7 and adapted to blow hot air into the air passage 14 by means of a built-in heater 17 and a blower 16 are provided. The heater unit 8 comprises a projecting portion 18 provided along the outer peripheral portion of the bedding portion 7 and on the side face portion of the direction of extension of the air passage 14, an air duct 19 projecting downward from the projecting portion 18 and having an inside cavity communicated with the blower 16, and a suction opening 20 provided through the outer fence portion of the air duct 19 and adapted to allow a flow of air in from the side face portion of the bed mattress 23. Therefore, air is surely sucked from the suction opening 20 of the bed mattress 23 and warm air is fed to the air passage 14 by the blower 16 and the heater 17 and is uniformly blown from each blowout hole to the whole bedding which is put over the surface of the bedding portion 7.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electric bedding with a drying function that can be used on a bed mattress and can dry the entire bedding.

0002

2. Description of the Related Art Conventionally, this type of bedding dryer has generally had a structure as shown in FIGS. 4 and 5. That is, the user inserts the ventilation mat 3 between the futon 1 and the comforter 2, and then inserts the ventilation hole 4 provided at the end of the ventilation mat 3.
By communicating with the ventilation passage 5 and further communicating with the ventilation hole 4 through the ventilation passage 5, a warm air generator 6 having an electric heater is sent to the ventilation mat 3, and the mattress 1 and the comforter 2 are heated. I was able to dry it.

0003

[Problems to be Solved by the Invention] However, with such a conventional structure, when in use, the ventilation mat 3 is inserted into the center of the bedding, the wrinkles are smoothed out so that warm air can reach the ends of the mat, and the ventilation passages 5 are Also, a complicated operation of setting the hot air generator 6 was required. If the blower mat 3 is inserted between the bedding in an uneven manner, there is a problem in that uneven drying occurs.

[0004] Furthermore, since the hot air generator 6 must be installed within the reach of the ventilation path 5, when used on a bed mattress, the installation height of the hot air generator 6 must be adjusted to match the height of the bed mattress. There was the inconvenience of having to make adjustments.

[0005] Therefore, the present invention provides an electric bedding with a drying function that does not require the labor of placing a ventilation mat, is easy to use on a bed mattress, and can reliably blow air even when a comforter is hung from above. The purpose is to obtain.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the electric bed with a drying function of the present invention is installed on a bed mattress and has an internal ventilation path and a blow-off hole on the surface communicating with this ventilation path. a bedding section; and a hot air unit configured integrally with the bedding section and blowing warm air into the ventilation path using a built-in heater and blower, the warm air unit including the ventilation section at an outer periphery of the bedding section. a protrusion provided on a side surface in the direction in which the path extends; a wind tunnel that protrudes downward from the protrusion and has a cavity therein that communicates with the blower; and a wind tunnel provided on the outer shell of the wind tunnel that extends from the side surface of the bed mattress. It is provided with a suction port through which air flows.

[0007]

[Function] With the above structure, the electric bedding with a drying function of the present invention blows warm air into the bed from the hot air unit integrated with the bedding part through the ventilation path and the blow-off hole inside the bedding part. At the same time, the entire bedding can be dried in its used state. Air is sucked in through the wind tunnel from the side surface of the bed mattress, and the air inlet is not blocked by a comforter or the like, so the air blowing operation can be performed reliably.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 3, reference numeral 7 denotes a bedding section, which is integrated with a hot air unit 8 provided at a corner thereof. As shown in FIG. 2, the cross-sectional structure of the bedding portion 7 is made by laminating a non-breathable outer fabric 9 and hard cotton 10, and forming irregularities by intermittently providing band-shaped heat-welded parts 9a. The first part 9a has a large number of blow-off holes 11.
mat 10a and urethane foam (density 40 kg/m3)
, hardness 20kg, t25mm, closed cell) 12 and lining cloth 1
It has a structure in which a second mat 12a is laminated and bonded with a second mat 12a in which grooves perpendicular to the recesses are pressed. The grooves of the first and second mats 10a and 12a communicate with each other in a three-dimensional cross shape, thereby forming a ventilation path 14 that communicates with the blow-off hole 11.
and the second mat 12a are sewn together with a hem cloth 15 at the outer periphery.

In addition, as shown in FIG. 1, a second mat 12
The ventilation path 14 of the groove part a and the blower 16 inside the hot air unit 8 are connected via a hot air outlet, and a heater 17 is provided between them. The outer case of the warm air unit 8 has a protrusion 18 on one side thereof.
A wind tunnel 19 is connected further downward, and a suction port 20 is formed in the outer part of the wind tunnel 19. A filter guide is provided on the inner surface of the suction port 20, and the dustproof filter 21 is inserted from the top surface of the hot air unit 8. Further, a rib 22 is provided on the lower surface of the hot air unit 8 to ensure a predetermined distance between the bed mattress 23 and the suction port 20.

With this configuration, as the blower 16 operates, air is sucked in as shown by the two-dot chain line in FIG. Warm air is blown. That is, even if a comforter or the like is hung from above, the suction port 20 is located between the wind tunnel 19 and the bed mattress 23 to ensure suction, so that reliable drying is possible.

Furthermore, since the dust filter 21 is inserted and pulled out from above, it is easy to handle even when the wind tunnel 19 is installed near a wall.
is on the side of the bed mattress 23, and the ribs 22 are provided, so that the bed mattress 23 is prevented from blocking the suction port 20, and suction can always be ensured.

[0013] In the above embodiment, the protrusion 18 and the wind tunnel 19 were constructed from the outer case of the hot air unit 8.
These are separate parts and the hot air unit 8 is attached using magnets, etc.
A similar effect can be obtained even if the device is removably attached to the outer case, making it easier to use during transportation and the like.

[0014]

Effects of the Invention As is clear from the above description, the electric bedding with a drying function of the present invention has an internal ventilation path, a bedding portion having an air outlet on the surface communicating with the ventilation path, and a bedding portion that is integrated with the bedding portion. and a hot air unit that blows hot air into the ventilation path using a built-in heater and a blower,
The warm air unit includes a protrusion provided on a side surface of the bedding section in an extending direction of the ventilation path, and a wind tunnel that protrudes downward from the protrusion and has a cavity therein that communicates with the blower. Since the wind tunnel is provided with a suction port which is provided in the outer part of the wind tunnel and allows air to flow in from the side surface of the bed mattress, the following effects can be obtained. (1) There is no need to lay down a ventilation mat, etc., and the entire bedding can be dried evenly while in use. (2) Even if a comforter is hung over the top, suction can be secured without blocking the suction port, and the air blowing load can be reduced, allowing smooth air blowing even with a thin and compact type blower with low air blowing pressure. This allows for reliable drying.
