Description

  The present invention relates to an air purifier having an installation state detection unit for detecting two types of installation states of floor-standing installation and wall-mounted installation, and a mechanism for opening and closing the air outlet based on the detection result of the installation state detection unit. It is.

  In order to efficiently purify indoor air, it is preferable that the air purifier is configured so as to blow clean air from the installed wall to the opposite wall and circulate the air in the entire room. For this purpose, the air cleaner is generally configured to form a blower outlet on the upper surface so that the room air is largely convected.

  In such an air cleaner, in order to improve usability, there is known an apparatus in which both installation states of floor installation and wall installation can be selected (Patent Document 1). When a structure with an air outlet provided on the upper surface of the air purifier is adopted, when the air purifier is used in a wall-mounted state, the clean air exhausted from the air outlet on the upper surface of the air cleaner collide. Since the air exhausted from the air outlet also flows around the surrounding room air, there is a problem that dust or the like contained in the entrained room air collides with and adheres to the ceiling, which causes the ceiling to become dirty. In addition, in an air purifier that exhausts air containing negative ions, there is a problem that dust or the like in indoor air is charged by negative ions and collides with and adheres to the ceiling together with the exhaust flow, making the ceiling more likely to become dirty. is there.

In order to solve the above-described problem, Patent Literature 1 includes an installation state detection unit that detects the installation state of the air cleaner, and when the wall-mounted installation state is detected, the air cleaner is attached to the air outlet on the upper surface of the air cleaner. By reducing the opening angle of the louver, the wind direction of the clean air exhausted from the air outlet is changed from directly above to diagonally forward, and the air exhausted from the air outlet is prevented from colliding with the ceiling.
JP 11-151414 A

  However, since the position of the air outlet of the air cleaner of Patent Document 1 is on the upper surface, the clean air exhausted to the ceiling collides when the wall-mounted position is close to the ceiling. Since the exhausted clean air collides with the ceiling, the flow of the exhausted clean air is limited, and the wind speed of the clean air exhausted by the collision with the ceiling decreases, so the air does not flow to the back of the room, There was a problem that air could not be circulated greatly throughout the room, an air short (clean air re-intake) occurred, and the air in the entire room could not be purified efficiently.

  In addition, it is conceivable to install the air cleaner upside down as a countermeasure against this problem, but the operation panel, display panel, label, etc. will be reversed, and the user will determine the display contents on the operation panel. It becomes difficult, and the problem that usability is bad arises.

  An object of the present invention is to provide a mechanism for changing the air outlet without changing the direction of the air cleaner according to the installation state.

The flow of the exhausted clean air is not limited, and the wind speed of the exhausted clean air is not reduced, and there is an effect that the air can be circulated widely throughout the room.

  According to claim 2, when installing on the floor, the pin is pushed up by the installation surface, and the pushed-up pin detects the installation state by operating the switch. There is an effect.

  According to the third aspect, since the upper air outlet is opened and closed by the upper lid operated by motor control, the upper air outlet can be automatically opened and closed according to the detection result of the installation state detection unit. .

  According to claim 4, in any installation state of floor-standing installation or wall-mounted installation, since it is only one of the first air outlet or the second air outlet, the air volume is increased compared to the first embodiment, and The wind speed is also increased, and the range in which the indoor air circulates can be widened. Also, since the second air outlet is configured to be blocked by the installation surface when installed on the floor, the second air outlet is used to close the second air outlet. There is an effect that the configuration can be simplified without requiring a special configuration.

  A first embodiment of the present invention will be described in detail below with reference to FIGS.

  Reference numeral 1 denotes a synthetic resin main body having a first air outlet 2 on the upper surface, a second air outlet 3 on the left and right side surfaces, and air inlets 4 on the front side surfaces and both side surfaces. An air passage 5 is formed in the main body 1 so as to communicate the air inlet 4 with the first air outlet 2 and the second air outlet 3, and the air passing through the air air passage 5 on the back surface of the air inlet 4. Is provided. A blower fan 7 is disposed in the blower passage 5, and a motor 8 that drives the blower fan 7 is disposed in the main body 1. The first air outlet 2 is provided with an upper lid 9 for opening and closing the first air outlet 2, and the upper lid 9 is controlled to be opened and closed by a motor (not shown) controlled by a control unit (not shown). It is like that. The control unit, the motor controlled by the control unit, and the upper lid 9 constitute an opening / closing mechanism.

Reference numeral 10 denotes an installation state detection unit disposed at the bottom of the main body 1. When the main body 1 is placed on the floor, the tip 11 abuts against the installation surface and slides in the vertical direction, and the tip of the pin 11 The spring 12 is urged in a direction protruding from the main body 1 and the switch 13 is operated by the pin 11.
Thus, in the floor-standing installation state shown in FIG. 2, the pin 11 abuts on the installation surface and is pushed up into the main body 1, the pin 11 operates the switch 13, and the switch 13 is turned on. Based on the output of the switch 13, in the floor-mounted installation state, the control unit opens the upper lid 9 to open the first air outlet 2. By opening the first air outlet 2, the indoor air sucked from the air inlet 4 by driving the blower fan 7 is purified through the filter 6, and the air is discharged from the first air outlet 2 and the second air outlet 3. Exhausted.
In the floor-standing installation state, the first air outlet 2 formed on the upper surface of the main body 1 is opened, and the indoor air is widely circulated by the exhaust flow exhausted from the first air outlet 2, so that the efficiency of purifying the indoor air is improved. Can be improved. Moreover, since clean air is exhausted also from the 2nd blower outlet 3 formed in the both sides | surfaces of the main body 1, coupled with the exhaust flow from the 1st blower outlet 2, the circulation efficiency of indoor air can be improved further.
In the wall-mounted state shown in FIG. 3, the tip of the pin 11 protrudes downward from the main body 1 by the biasing force of the spring 12, and the switch 13 is turned off. Based on the output of the switch 13, the control unit closes the first air outlet 2 with the upper lid 9 in the wall-mounted state. Since the first outlet is closed, the exhaust flow does not collide with the ceiling, and it is possible to prevent the exhaust flow flowing in the surrounding room air from contaminating the ceiling. Further, since the exhausted clean air does not collide with the ceiling, the flow of the exhausted clean air is not restricted, and the wind speed of the exhausted clean air is not reduced. When the first air outlet 2 is closed, the amount of air blown from the second air outlet 3 is increased, so that the air flows into the interior of the room and a large circulation of air over the entire room can be performed. It can be prevented from occurring.

  In the first embodiment, both the air inlet 4 and the second air outlet 3 are formed on the side surface. However, the position of the surface on which the air inlet 4 is formed on the side surface and the second air outlet 4 are arranged so that an air short circuit does not occur on the side surface. A step 15 is provided with respect to the position of the surface where the outlet 3 is formed (see FIG. 6). Further, as shown in FIG. 6, the surface on which the second air outlet 3 is formed is gently angled, and the air exhausted from the second air outlet 3 is sucked from the air inlet 4. The air is exhausted rearward and leftward and rightward so that it is not trapped by the airflow and does not collide with the rear wall, so that the room air circulates widely.

  Next, a second embodiment of the present invention will be described in detail below with reference to FIGS. The same parts as those in the first embodiment described above are denoted by the same reference numerals and description thereof is omitted.

  In the second embodiment, the second air outlet 14 is formed on the bottom surface of the main body 1. In the wall-mounted state, the first blower outlet 2 is closed by the control unit as in the first embodiment, so that the indoor air sucked from the intake port 4 by driving the blower fan 7 is purified through the filter 6. And exhausted from the second outlet 14. On the other hand, in the floor-mounted installation state, the first air outlet 2 is opened by the control unit and the second air outlet 14 is closed by the installation surface, so that the indoor air sucked from the air inlet 4 by driving the blower fan 7 is The air is purified through the filter 6 and exhausted from the first air outlet 2.

In 2nd embodiment, since it becomes only any one of the 1st blower outlet 2 or the 2nd blower outlet 14 in any installation state of floor-standing installation and wall hanging installation, air volume becomes large compared with 1st embodiment. In addition, the wind speed is increased and the indoor air can be circulated greatly. Moreover, since the 2nd blower outlet 14 was set as the structure obstruct | occluded by the installation surface at the time of floor-standing installation, the special structure for obstruct | occluding the 2nd blower outlet 14 is not required, and a structure can be simplified. .
