Problems solved by technology

However, how to ensure the sealing between the flexible and movable film-like belt 19 and the rigid box body is a major problem in the performance of the device.
In fact, the dust suction device provided by this patent cannot be well solved due to the sealing problem. When working, the suction force of the suction hole 19a is very small, and the dust suction speed is very slow.

Embodiment 1

[0038] Figure 4 Shown is a cross-sectional view of an embodiment of an air-conditioning indoor unit with a filter dust removal device provided by the present invention. It can be seen from the figure that the air-conditioner indoor unit with a filter dust removal device includes a casing 10 and a casing 10 is provided with an air inlet 11 and an air outlet 12, and an annular heat exchanger 13 is arranged inside the casing 10, and a fan 15 is arranged around the center of the annular heat exchanger 13, and the air outlet of the fan 15 is connected to the casing 10 The air outlet 12 is provided with an air deflector 16 on the air outlet, and a dust filter 17 is provided on the outside of the annular heat exchanger 13; the dust filter 17 of the present invention is a rolling door type rigid with a supporting frame Filter screen; the two ends of the hard filter screen with the rolling door type of the support frame are provided with rollers 18 that drive the hard filter screen of...

Embodiment 2

[0042] Image 6 Shown is a cross-sectional view of another air-conditioning indoor unit with a filter dust removal device provided by the present invention. It can be seen from the figure that the air-conditioner indoor unit with a filter dust removal device includes a casing 10 and a casing 10 An air inlet 11 and an air outlet 12 are arranged on the top, and an annular heat exchanger 13 is arranged inside the casing 10, and a fan 15 is arranged around the center of the annular heat exchanger 13, and the air outlet of the fan 15 is connected to the bottom of the casing 10. The air outlet 12 is provided with an air deflector 16 on the air outlet, and a dust filter 47 is provided on the outside of the annular heat exchanger 13; the dust filter 47 in this embodiment is a flexible filter; Both ends of the flexible filter 47 are provided with rollers 48 that drive the flexible filter to move; both sides of the flexible filter are provided with uniformly arranged through holes 471, ...

Embodiment 3

[0045] The difference between this embodiment and the second embodiment lies in that the structure of the flexible filter is different. The flexible filter screen described in Embodiment 2 is an annular filter screen, and through holes are arranged on both sides of the filter screen, and ratchets are provided at both ends of one of the rollers 48, and the ratchets of the ratchet are connected with the flexible filter screen. The through-holes on both sides are snapped together. The driving motor drives the roller 48 provided with the ratchet to rotate, and the ratchet drives the flexible filter to move axially. Since the heat exchanger 13 is annular, a plurality of support rollers 45 are provided under the flexible filter 47 . To make the flexible filter net 17 in a bent shape.

[0046] In this embodiment, in order to reduce the ratchet wheels at both ends of the supporting roller and the roller, the flexible filter is fixed and wound on the rollers at both ends.

Abstract

The invention pertains to air conditioner field, and specifically is an air conditioner indoor set with a filter screen dust removing device, comprising a housing, an air inlet and an air outlet disposed on the housing, a circular heat exchanger disposed in the housing, a fan is disposed at the circulating center of the circular heat exchanger, an air outlet of the fan communicating with the air outlet of the housing, and a dust removing filter screen disposed at the outer side of the circular heat exchanger; wherein a rolling shaft activating the filter screen is disposed at the two ends of the filter screen; a dust absorption pipe formed of a helical groove pipe and an axial straight groove pipe sleeving each other is disposed near to the filter screen, a hose communicating with the dust absorption pipe is disposed at the terminal of the straight groove pipe of the dust absorption pipe, and an electric motor rotating the helical groove pipe is disposed at the terminal of the helical groove pipe. An inhalation pore is formed by a straight groove pipe and a helical groove pipe sleeving each other with airtightness, wind power is centralized, and dust is removed with high efficiency; filter screen dust is removed roundly in condition that the indoor set outer cover is not opened.

Description

technical field [0001] The invention relates to a dust removal device, in particular to an air conditioner indoor unit with a filter net dust removal device. Background technique [0002] Existing air-conditioning indoor units such as figure 1 , 2 As shown, there is a casing 4, an air inlet 8 is provided on the top and the front of the casing 4, an air outlet 9 with a wind deflector 3 is provided on the bottom front side slope of the casing, and a ring-shaped heat sink is arranged inside the casing. The exchanger 6 is provided with a fan 7 around the center of the annular heat exchanger 6 , and the air outlet of the fan 7 is connected to the air outlet 9 of the casing 4 . In order to prevent dust from invading the inside of the body, an air filter 5 is provided between the heat exchanger 6 and the casing, and the indoor air is sucked in by the fan 7, and the sucked air exchanges heat with the heat exchanger 6 to become cold or hot wind. Air outlet 9 blows out indoors. Th...
