DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a deodorizing apparatus for effectively removing living odors drifting in a bed living space, for example, body odor and human urine odor emitted from a patient, so that a comfortable bed life can be achieved. It is about a bed.

[0002]

2. Description of the Related Art In recent years, Japan has become one of the longest living countries in the world, and it is said that there is no time to create an environment suitable for an aging society. Against this background, as part of the creation of an environment, at home, the elderly can live in a comfortable bed, and it is easy to use for long-term caregivers who are forced to live in bed. In-home beds suitable for home care have been devised. For example, the living odor in the living space around the bed is associated with the bed life for many years, and especially the body odor and the urine odor emitted from the long-term caregiver, the elderly, etc. are very worrisome. At present, as a countermeasure against this, there are many cases where a commercially available air purifier is installed. In such an air purifier, the setting range of the target dust and the odor component that can be treated is wide, and the effect is often insufficient for the price and size. Therefore, recently, a bed provided with a deodorizer 2 on a bed 1 has been proposed (see FIGS. 4 and 5). In such a bed 1, a deodorizer 2 is attached to a lower portion of the bed, and air on the bed 1 is sucked through a duct 4 formed in a footboard 3 to deodorize the bed.

[0003]

However, the area under the bed 1, that is, immediately below the bottom, is blocked by a frame, a mattress, a futon, or the like, and the air stays there. It is desired to create a flow of air and reduce the humidity. The present invention has been proposed based on such a background, and promotes the ventilation of air in the space under the bottom as well as the atmosphere near the bottom of the bed to adjust the humidity so that a comfortable bed is provided. It is an object of the present invention to provide a bed provided with a deodorizing device so that a person can live a life.

[0004]

In order to solve the above-mentioned problems, the present invention provides a deodorizing device provided under the bottom with a bed.
From above the bottom of the bed through the suction air passage
The atmosphere is introduced and the deodorizing treatment is performed.
Is a deodorizing filter to remove odor components such as human odor.
Air in the vicinity of the bed to this deodorizing filter.
To encourage clean air to return to the room.
A plurality of suction pipes in the middle of the suction air passage.
Forming an opening for driving the fan of the deodorizer,
Suction the atmosphere under the bottom into the suction air passage.
Was. In the above configuration, a humidity sensor may be arranged below the bottom, and the operation of the deodorizer may be controlled based on a detection signal from the humidity sensor.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a bed provided with a deodorizing device according to the present invention will be described with reference to the accompanying drawings, which show one embodiment. FIG. 1 shows a bed 10 provided with a deodorizing device. Under the bottom 11 of the bed 10, a deodorizing machine 12 is attached. Bed 1
0 foot board 13 has an air suction port (not shown).
And the deodorizer 12 disposed below the bottom 11.
And a duct 14 as a suction air passage communicating with the air passage.

The deodorizer 12 operates an operation button (not shown) provided on a hand switch (to be described later) disposed on a fence or the like (not shown) near the bedside to thereby operate the electric bottom adjustment mechanism of the bed 10. It is configured to operate by receiving electric power via a controller (described later). The deodorizer 12 has a well-known structure, and has a deodorizing filter (not shown) for removing body odor emitted from the user and the bed 10, particularly odor components such as human urine odor. Fan 1 for introducing air in the vicinity of bed 10 to the filter for use to promote returning of the purified air to the room.
5 (see FIG. 2). As the deodorizing filter, a filter having a high effect of removing odor components such as body odor and human urine odor is used. Can be applied.

The duct 14 is provided on the foot board 13.
It communicates with an air suction port in the footboard 13 through an extendable bellows passage portion 16 extending below and extends in a substantially horizontal direction below the bottom 11 to the deodorizer 12. A plurality of suction openings 17 are cut and raised in the middle of the passage in the duct 14, and by driving the fan 15 of the deodorizer 12, the bottom 11
The lower atmosphere is sucked into the duct 14.

A humidity sensor 18 is provided directly below the bottom 11. The humidity sensor 18 is adapted to receive a detection signal into a controller of the electric bottom adjustment mechanism.

Accordingly, a control configuration of the deodorizing device will be described. As shown in FIG. 3, the controller 19 of the electric bottom adjustment mechanism incorporated in a control box (not shown) mounted on the middle floor or the like below the bottom of the bed 10 includes a hand switch 20 and an electric bottom adjustment mechanism. The head motor 21, the leg motor 22, and the vertical motor 23, which are drive sources, are connected via signal lines. The controller 19 is configured to receive a detection signal from the humidity sensor 18, and a deodorizer is provided from the controller 19. 12 is supplied with a control signal. The controller 19 is set with a procedure for controlling the deodorizing operation of the deodorizer 12 based on a detection signal from the humidity sensor 18 by operating an operation button provided on the hand switch 20.

Bed 1 equipped with a deodorizing device according to the present invention
0 is configured as described above, and its operation will be described next. When the operation button provided on the hand switch 20 is turned on, the controller 19 can recognize that the operation button has been turned on, and the controller 19 supplies power to the deodorizer 12 to drive the fan 15. it can. Then, air near the mattress M on the bottom 11 is sucked into the duct 14 from the air suction port of the footboard 13 through the bellows passage portion 16 and introduced into the deodorizing filter of the deodorizer 12, from which the odor component is introduced. It is removed and returned to the room as clean air again.

On the other hand, from the duct 14 below the bottom 11,
The atmosphere below the bottom 11 is sucked from the plurality of suction openings 17 in the middle of the passage, and is introduced into the deodorizing filter of the deodorizer 12 to remove odor components.
As described above, the atmosphere under the bottom 11 is sucked into the duct 14 during operation, so that the atmosphere under the bottom 11 does not stay, ventilation and dehumidification are promoted, and furthermore, odor is reduced. Since it can be removed, the atmosphere around the bed can be further reduced. The atmosphere in the space below the bottom 11 is monitored by a humidity sensor 18, and when the humidity in the atmosphere increases, the controller 19 determines that the atmosphere is stagnant, and the controller 19 sends the electric power to the deodorizer 12 to the fan 15. A control signal is supplied to increase the deodorizing ability. By continuing the above operation control, the bottom 1
First, ventilation of the atmosphere below the bottom as well as the air near the mattress M is promoted, and suitable humidity can be maintained, and a comfortable living space is provided.

[0012]

According to the present invention, not only on the bottom,
Ventilation of the atmosphere beneath the bottom can be promoted to reduce deodorization and humidity, resulting in a comfortable bed life.
