Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a filter assembling structure suitable for being incorporated in an air conditioner.

[0002]

[Prior Art]

 A vertical sectional view of a conventional wall-mounted indoor unit of a separation type air conditioner is shown in FIG. In FIG. 3, 1 is a main body, 2 is a suction grill provided in the upper front part of the main body 1, 3 is a heat exchanger, 4 is a cross-row type fan arranged below the heat exchanger 3, and 5 is the main body. 1 is a blower outlet provided in the lower part of the front surface, 6 is a louver provided at the blower outlet 5, 7 is a drain pan provided under the heat exchanger 7, and 8 is provided behind the suction grill 2. A filter 9 is a casing forming an air flow path 10 in the main body 1 from the suction grill 2 to the air outlet 5. As shown in FIG. 2, the filter 8 is a clean filter including a pre-filter 81 for capturing large dusts in the room air, an electrostatic filter for removing cigarette smoke and odors, a deodorizing filter, and the like. Comprised of a filter 82 and a holding cover 83. The clean filter 82 is housed in the holding cover 83 and the three claws 84 provided on the prefilter 81 are locked in the engaging holes 85 provided on the holding cover 83. Assembled by

During operation of the air conditioner, the fan 4 rotates, and a refrigerant from an outdoor unit (not shown) circulates in the heat exchanger 3. Then, the indoor air passes through the suction grill 2 and is sucked into the main body 1 as shown by the solid arrow, and the dust contained therein is removed by passing through the filter 8 to flow through the heat exchanger 3. It is cooled or heated by passing it, is energized by the fan 4, and is guided to the louver 6 from the outlet 5 and blown out into the room.

[0004]

[Problems to be solved by the device]

 In the above air conditioner, the prefilter 81 of the filter 8 has to be cleaned approximately every two weeks, but each time, the three claws 84 are removed from the engaging holes 85, and the clean filter 82 and the holding cover 83 are removed. There was a problem that it was troublesome to remove from.

[0005]

[Means for Solving the Problems]

 The present invention has been proposed to solve the above problems, and the gist of the present invention is to provide a clean filter by a holding claw provided in a holding cover in a filter assembling structure in which a clean filter is tying and assembled with a prefilter. Is held on the holding cover, pins are provided on both sides of the holding cover, and handles are provided on the upper side of the holding cover, and the projections provided on the pins and the handles are engaged with the engagement grooves and the engagement holes provided on the prefilter. Thus, the holding cover is locked to the pre-filter, which is an assembly structure of the filter.

[0006]

[Action]

 Since the present invention has the above-described structure, the clean filter is held by the holding cover by the holding claw, and the holding cover is engaged with the prefilter by engaging the pin and the projection with the engaging groove and the engaging hole. Stop.

[0007]

【Example】

 One embodiment of the present invention is shown in FIG. The filter 100 includes a prefilter 101, a clean filter 102, and a holding cover 103. The holding cover 103 is formed by injection molding a flexible synthetic resin and has a frame shape as a whole. A holding claw 104 protruding inward is provided on the front surface and the rear surface thereof, and the holding claw 104 holds the cleaning filter 102 stored in the holding cover 103 so as not to come out. Pins 105 projecting laterally are provided on the lower portions of both sides of the holding cover 103, and engaging grooves 106 with which the pins 105 are engaged are cut from both sides of the frame 107 of the prefilter 101 from its front edge. There is. Further, a handle 108 that rises obliquely upward is provided on the rear portion of the upper surface of the holding cover 103, and a tongue piece 109 that extends forward is formed on the lower portion of the handle 108. Then, a protrusion 110 protruding downward is formed at the center of the lower surface of the tongue piece 109, and an engagement hole 111 with which the protrusion 110 is engaged is formed in the upper surface of the frame 107.

When assembling the filter 100, the clean filter 102 is stored in the holding cover 103 and held by the holding claw 104. Next, the pair of pins 105 are aligned with the entrances of the engaging grooves 106 and the holding cover 103 is pushed forward. The pre-filter 101, the clean filter 102, and the holding cover 103 are integrally assembled by engaging with the inner part and the projection 110 being locked in the engaging hole 111.

When cleaning the pre-filter 101, when the handle 108 is pulled down obliquely as shown by the arrow, the tongue 109 tilts and the projection 110 is pulled up and disengaged from the engagement hole 111. To do. Then, when the holding cover 103 is lifted diagonally upward by holding the handle 108, the pin 105 is pulled out from the engaging groove 106, and the holding cover 103 is separated from the prefilter 101.

[0010]

[Effect of the device]

 In the present invention, the holding filter provided on the holding cover holds the clean filter on the holding cover, pins are provided on both sides of the holding cover, a handle is provided on the upper part of the holding cover, and the pin and the protrusion provided on the handle are provided. Since the holding cover is locked to the prefilter by engaging the engaging groove and the engaging hole provided in the prefilter, the clean filter is held by the holding claw on the holding cover, and the pin and the projection are engaged in the engaging groove and the engaging hole. It can be assembled by engaging, and the holding cover and the clean filter can be simultaneously removed from the prefilter only by pulling the handle. Therefore, it becomes possible to easily and quickly clean the prefilter.
