Detailed Description
In order that the utility model may be understood more fully, the utility model will be described with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the utility model. This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1-7, in this embodiment, a dustproof filtering structure for a base 1 of an indoor unit of an air conditioner includes a base 1 and a filter screen 2, wherein a vent hole is formed in a back area of the base 1, so that not only is an air quantity of heat exchange of external air entering the indoor unit from the vent hole increased, but also weight of the base 1 is reduced, and cost is reduced.
In order to prevent dust from entering the indoor unit from the ventilation holes, the filter screen 2 of the present embodiment is detachably covered at the ventilation position, thereby playing a role in dust-proof filtration. Specifically, at least one upper fastener 21 and at least one lower fastener 22 are respectively formed on the upper side and the lower side of the back surface of the filter screen 2, and the upper fastener 21 is matched and clamped with the upper edge of the vent hole; the lower fastener 22 is engaged with the lower edge of the vent hole.
In this embodiment, the lower fastener 22 includes a first connecting rib integrally formed on the back surface of the filter screen 2 in a protruding manner, and a first bending rib bent from the outer end of the first connecting rib towards the lower edge of the filter screen 2, where the first bending rib, the first connecting rib and the back surface of the filter screen 2 together enclose a first clamping interface capable of being clamped and matched with the lower edge of the vent hole.
In this embodiment, the upper fastener 21 includes a second connecting rib integrally formed on the back surface of the filter screen 2 in a protruding manner, and a second bending rib bent from the outer end of the second connecting rib towards the upper edge direction of the filter screen 2, where the second bending rib, the second connecting rib and the back surface of the filter screen 2 together enclose a second clamping interface capable of being clamped and matched with the upper edge of the vent hole.
Therefore, when the filter screen is installed, the first clamping connector of the lower fastener 22 is clamped with the lower edge of the vent hole, the filter screen 2 is bent, the second clamping connector of the upper fastener 21 is clamped with the upper edge of the vent hole, the assembly between the filter screen 2 and the base 1 is completed, and the quick installation of the filter screen 2 is realized. On the contrary, when the filter screen 2 is detached, the first clamping port of the lower fastener 22 is separated from the lower edge of the vent hole, and the second clamping port of the upper fastener 21 is separated from the upper edge of the vent hole, so that the filter screen 2 can be completely detached, and the filter screen 2 can be quickly detached. By adopting the structure form of the quick assembly disassembly filter screen 2, when the filter screen 2 is damaged, the new filter screen 2 can be directly assembled, disassembled and replaced without scrapping the base 1, thereby reducing the production reject ratio cost and the later maintenance cost.
In this embodiment, the shaping of filter screen 2 back has three along the last fastener 21 of filter screen 2 length direction side by side and three along filter screen 2 length direction side by side the lower fastener 22 of arranging to through the joint cooperation between a plurality of last fastener 21 and lower fastener 22 and the ventilation hole, thereby ensure that filter screen 2 can install on base 1 more stably, be difficult for taking place the drunkenness, abnormal problems such as becoming flexible. Secondly, the shape of the first clamping interface of the lower fastener 22 is matched with the lower edge of the vent hole, and the shape of the second clamping interface of the upper fastener 21 is matched with the upper edge of the vent hole, so that the back surface of the filter screen 2 can be tightly attached to the edge of the vent hole, gaps are reduced, and the dust filtering effect on the outside air is improved.
In this embodiment, each upper fastener 21 is vertically aligned with each lower fastener 22, thereby improving the stability of the screen 2 mounted on the base 1.
In this embodiment, the filter screen 2 includes a net frame and a net curtain fixed on the net frame, wherein the net frame is made of PP material by injection molding, and the characteristics of good ductility and toughness of the PP material are utilized, so that the filter screen 2 can be bent by snapping, and the durability is improved.
