Description

The present invention relates to an air conditioner , and in particular, an air conditioner equipped with a filter cleaning device that automatically removes dust, dust, lint and the like (collectively referred to as “dust” in the present invention) trapped in a filter. About.

  2. Description of the Related Art Conventionally, an air conditioner having a filter cleaning device function capable of removing dust attached to a filter by moving the filter and easily collecting the removed dust has been disclosed (for example, see Patent Document 1). ).

JP 2004-28487 A (page 5-8, FIG. 1)

However, the air conditioner disclosed in Patent Document 1 has the following problems.
(A) The filter in the filter cleaning section is pushed out of the machine while pushing up the open / close panel provided on the front panel of the air conditioner during cleaning, that is, the filter is visually recognized from the inside, so the design of the apparatus As a result, the cleanliness of the device is impaired and the occupants may feel uncomfortable and the competitiveness of the product is reduced.
(Ii) Since the filter moving mechanism in the filter cleaning section includes a rack formed at the center in the width direction of the filter, a pinion that rotates in mesh with the rack, and a drive motor that rotates the pinion. If multiple filters (same for multiple filter cleaning units) are installed in the air conditioner, the drive motor will become more than one, resulting in increased manufacturing costs, increased equipment weight, and an air conditioner equipped with this. The product becomes less competitive as it increases size and restricts design.

The present invention has been made in view of the above, and can be cleaned while the filter is concealed in the machine, and the motor that moves the filter even if a plurality of filters are installed in the air conditioner. An object of the present invention is to provide an air conditioner having a filter cleaning device that can prevent the expansion.

An air conditioner according to the present invention has a housing that has an air inlet that opens to the top surface and sucks air, and an air outlet that opens to the ground side and blows out the sucked air.
A blower fan that is installed in the housing and blows out the air sucked from the suction port from the air outlet;
A front guide plate and a rear guide plate that form a blow-out side air passage between the blower fan and the outlet;
A heat exchanger installed in the flow of air formed by the blower fan;
A filter that is disposed between the suction port and the heat exchanger and captures dust in the air sucked from the suction port;
A filter cleaning device installed in the housing and cleaning the filter;
The filter cleaning device moves the filter, a filter moving unit, a dust removing unit that contacts the filter and removes dust captured by the filter, and dust that collects the dust removed by the dust removing unit A recovery unit,
The filter moving section, the filter, along the arcuate movement path in the housing, the upper edge of the filter reaches a position on the top surface side near the rear surface in the housing, and the lower edge of the filter moves in the housing. The range of reaching the position of the front guide plate near the front is reciprocated.

Therefore, in the air conditioner according to the present invention, since the filter moves in the casing along the arcuate movement path, the filter does not protrude outside the casing and is not visible from the outside of the casing. The design is improved and the cleanliness of the device is increased. Furthermore, since the plurality of filters are selectively moved by one motor, the number of installed motors is reduced, the motor capacity is reduced, and the apparatus cost is reduced. Therefore, product competitiveness is improved.

  Hereinafter, a filter cleaning apparatus according to an embodiment of the present invention will be described with reference to the drawings as a first embodiment in which one filter is installed and as a second embodiment in which two filters are installed. To do. In the following drawings, the same or corresponding portions are denoted by the same reference numerals, and a part of the description is omitted.

(Assembly of filter cleaning device)
FIG. 6 is a perspective view showing a state where the filter cleaning device shown in FIG. 1 is assembled. In FIG. 6, the shaft support protrusion 75 of the dust removing unit 70 enters the through hole 85 of the dust collecting unit 80, and the roll brush drive shaft 72 of the dust removing unit 70 is locked to the notch 84 of the dust collecting unit 80. Thus, the filter cleaning device 50 is assembled. At this time, the dust collecting unit 80 and the dust removing unit 70 are joined to each other in a rotatable manner with the intrusion part and the locking part as the rotation center.
That is, since the dust removing unit main body 74 of the dust removing unit 70 functions as an “opening / closing lid” of the dust collecting box 83 of the dust collecting unit 80, when the dust removing unit main body 74 is aligned with the dust collecting box 83, the dust removing unit A substantially sealed dust box is formed by the main body 74, the dust collection box 83, and the roll brush 71.

  Further, since the end surface of the dust removing unit main body 74 has entered the inside of the dust collection box 83, a small protrusion or a small recess is formed outside the end surface of the dust removing unit main body 74, and the inside of the end surface of the dust collecting box 83 is formed. If the small protrusions or small protrusions that can be locked to the small protrusions or small recesses are formed, the dust removing unit main body 74 and the dust collection box 83 are not easily separated by locking them. Dust is not accidentally dissipated from the dust box. Further, since the locking can be separated with a slight force, the operation of discharging dust from the dust box becomes easy.

(Attaching the filter cleaning device)
FIG. 7 is a cross-sectional view at an end portion in a side view schematically showing the air conditioner according to Embodiment 1 of the present invention. In FIG. 7, a cleaning device installation slope 18 for installing the filter cleaning device 50 is formed at the end of the housing 10 of the air conditioner 100. Therefore, the front door 12 is opened, and the filter cleaning device 50 can be easily attached or detached. At this time, the filter moving unit 60 holding the filter 40 (indicated by a slanting line in the lower right in the figure), the integrated dust removing unit 70 and the dust collecting unit 80 (same as the dust box, in the figure) May be attached separately or integrally.
In the above, the filter moving part locking protrusion 66 of the filter moving part 60 and the dust collecting part locking protrusion 86 of the dust collecting part 80 are illustrated as being mutually locked. It is not limited. For example, a protrusion formed on the other end surface may be locked (or fitted) in a groove formed on one end surface, and the filter moving unit 60 may be engaged with the cleaning device installation slope 18 of the housing 10. You may form the slope which stops and the slope which the dust collection | recovery part 80 latches, respectively.

(How to move the filter)
FIG. 8 is a cross-sectional view in side view for explaining a moving procedure of the filter in the filter cleaning device shown in FIG. 1. In FIG. 8, the filter 40 has been moved to the lower limit. That is, the filter 40 moves along the arcuate moving path 17 from the state where the upper edge 46 is at the position A (see FIG. 1) until the lower edge 47 reaches the position B.
In the “outward path” from position A to position B, the roll brush 71 rotates in the same direction (clockwise in the figure) as the moving direction of the filter 40 (substantially downward in the figure). Dust trapped in the gas 41 is removed. In particular, since the peripheral speed (Vb) of the roll brush 71 is slower (Vb <Vf) than the moving speed (Vf) of the filter 40, the dust trapped in the filter vent 41 is temporarily removed from the roll brush. After being collected on the biting side of 71 (the top surface side in the figure), it adheres to the roll brush 71 and is carried to the biting side (the ground side in the figure). The attached dust is scraped off by the scraping plate 81 and collected in the dust collection box 83.

On the other hand, the filter 40 that has reached the lowering limit is moved by the filter drive gear 61 that rotates in the reverse direction (clockwise in the drawing) and returns to the rising limit (see FIG. 1). That is, the upper edge 46 reaches the position A.
In the “return path” from the position B to the position A, the roll brush 71 stops rotating. Therefore, even if the dust that has not been removed in the forward path is removed in the return path, the dust is only collected on the biting side (the ground side in the figure) of the non-rotating roll-shaped brush 71 and bite. It is not carried to the delivery side (the top side in the figure). Therefore, the dust removed from the roll-shaped brush 71 does not dissipate out of the dust collection box 83.

[Embodiment 2]
(Air conditioner)
9 and 10 are perspective views schematically showing a filter cleaning device installed in the air conditioner according to Embodiment 2 of the present invention. FIG. 9 is before assembly, and FIG. 10 is after assembly.
9 and 10, an air conditioner 200 (not shown) is formed by a housing 10, a blower fan 20 that is installed in the housing 10 and sucks air and blows out the sucked air, and the blower fan 20. The heat exchanger 30 that is disposed in the air passage that harmonizes the sucked air, the first filter 40a and the second filter 40b that capture dust contained in the sucked air, and the first filter 40a and the second filter 40b. A first filter cleaning device 50a and a second filter cleaning device 50b, respectively, and a rotation output device 90 that alternatively outputs rotation to the first filter cleaning device 50a or the second filter cleaning device 50b. ing.

The first filter 40a and the second filter 40b are both the same as the filter 40 in the first embodiment.
In the drawing, the first filter cleaning device 50a arranged on the right side is the same as the filter cleaning device 50 in the first embodiment, and the first filter rotation input gear 63a and the first roll-shaped brush are disposed at the left end portion thereof. The rotation input gear 73a is located. On the other hand, the second filter cleaning device 50b arranged on the left side in the figure is the first in that the second filter rotation input gear 63b and the second roll-shaped brush rotation input gear 73b are located at the right end. Although different from the filter cleaning device 50a, the configuration except this is the same as that of the first filter cleaning device 50a (same as the filter cleaning device 50 shown in the first embodiment). That is, the filter rotation input gears 63a, 73a, 63b, and 73b are concentrated in the central portion of the housing in a front view.

(Rotation output device)
The rotation output device 90 includes one motor (not shown), a first filter rotation output gear 96a that can be meshed with the first filter rotation input gear 63a, and a first roller that can mesh with the first roll-shaped brush rotation input gear 73a. 1-roll brush rotation output gear 97a, a second filter rotation output gear 96b that can mesh with the second filter rotation input gear 63b, and a second roll-shaped brush rotation output that can mesh with the second roll brush rotation input gear 73b. A gear 97b (hereinafter, these may be collectively referred to as "filter rotation output gear 91"). That is, the rotation output device 90 selects a rotation distribution mechanism (not shown) that selectively transmits the rotation of one motor to any one of the filter rotation output gears 91 and the rotation of any one of the filter rotation output gears 91. And a rotation stopping mechanism (not shown) that stops at once.
Since the rotation output device 90 is fixed to the housing 10, the gears mesh with each other when the first filter cleaning device 50 a and the second filter cleaning device 50 b are attached to the housing 10. is there.

(How to move the filter)
Since the rotation output device 90 includes the filter rotation output gear 91, the rotation distribution mechanism, and the rotation stop mechanism as described above, the first filter 40a and the second filter 40b move in the following manner. Do (same as to be cleaned).
That is, the first filter 40a moves from the position A toward the position B (outward movement), and after the forward movement is completed, the second filter 40b moves from the position A toward the position B (outward movement). Then, after the both forward movements are completed, the first filter 40a is moved from the position B toward the position A (return movement), and after the return movement is completed, the second filter 40b is moved from the position B to the position A. Move toward (return trip).

In the forward movement, the first roll-shaped brush rotation output gear 97a and the first filter rotation-output gear 96a are set so that the peripheral speed of the first roll-shaped brush 71a is smaller than the movement speed of the first filter 40a. Each rotates in the opposite direction at a predetermined rotational speed (same as the rotational speed ratio). Similarly, the second roll-shaped brush rotation output gear 97b and the second filter rotation-output gear 96b are rotated at predetermined rotations so that the peripheral speed of the second roll-shaped brush 71b is smaller than the moving speed of the second filter 40b. Rotate in the opposite direction by the number (same as the rotation ratio).
Further, in the backward movement, the first filter rotation output gear 96a rotates while the first roll brush rotation output gear 97a stops rotating, and similarly, the second roll brush rotation output gear 97b stops rotating. In this state, the second filter rotation output gear 96b rotates.

Therefore, as in the first embodiment, the dust trapped by the first filter 40a and the second filter 40b is removed and collected in the first dust collection box 83a and the second dust collection box 83b. At this time, each of the first filter 40a and the second filter 40b is moved by one motor, and the time is alternatively shifted, so that the capacity of the motor is reduced. Can do. Therefore, an increase in manufacturing cost of the air conditioner 200 can be suppressed.
In the above, the backward movement is started after the forward movement of both the first filter 40a and the second filter 40b is completed, but the present invention is not limited to this, and the forward movement of the first filter 40a is performed. Further, after the backward movement is completed, the forward movement of the second filter 40b may be started.

(Filter confirmation switch)
FIG. 11 is a perspective view schematically showing a filter confirmation switch installed in the air conditioner according to Embodiment 2 of the present invention. A filter confirmation switch (hereinafter referred to as “switch”) 9 is installed at a position A of the housing 10 and is fixed to the switch base 1 and the switch base 1 fixed to the housing 10 side. The switch box 2, a fixed contact (not shown) fixed in the switch box 2, a moving contact (not shown) that is movably disposed in the switch box 2 and can be short-circuited and insulated from the fixed contact, and the movement It has an advancing / retreating portion 3 that has a contact and protrudes and retreats from the switch box 2, and a lever 4 that can freely come into contact with the advancing / retreating portion 3 and retreat.

The lever 4 is provided with a support protrusion (not shown) in the center, and the support protrusion is guided by a guide groove 6 formed in the switch base 1 so that it can be translated and rotated, and is attached in a direction away from the advance / retreat portion 3. It is biased by a biasing means (not shown) or gravity. That is, the lever 4 moves forward and backward and tilts (moves like a seesaw).
Therefore, when the upper edge 46a of the first filter 40a contacts the first contact portion 5a formed at one end of the lever 4, the lever 4 tilts and the first contact portion 5a rises. The second contact portion 5b formed at the other end of the lever 4 is lowered. Similarly, when the upper edge 46b of the second filter 40b contacts the second contact portion 5b of the lever 4, the lever 4 tilts, the second contact portion 5b rises, and the first contact portion 5a. Descends.
On the other hand, when both the upper edge 46a of the first filter 40a and the upper edge 46b of the second filter 40b are in contact with the first contact portion 5a and the second contact portion 5b of the lever 4, the lever 4 tilts. Therefore, the lever 4 comes into contact with the advancing / retreating portion 3 to retract the advancing / retreating portion 3. Therefore, the fixed contact and the moving contact are short-circuited by the retreat of the advance / retreat unit 3.

  That is, since the switch 9 is installed in the air conditioner 200, the first filter. When the cleaning device 50a and the second filter cleaning device 50b are attached, it is easily confirmed that they are installed at regular positions. Further, when the movement of one or both of the first filter 40a and the second filter 40b is started or when the movement is finished, both the first filter 40a and the second filter 40b are at the ascent limit (position A). It can be easily confirmed. At this time, the number of the switches 9 is one, and the structure is simple and small. Therefore, the switch 9 can be easily installed on the housing 10 and an increase in the manufacturing cost of the air conditioner 200 can be suppressed.

  Since the present invention has the above configuration, the filter can be cleaned while being hidden in the machine, and a plurality of filters can be cleaned with a single motor. It can be widely used as a cleaning device and as various air conditioners.
