The specific application of the pipe connection structure of this embodiment is that the pipe connection structure is used to connect with the fresh air device 120 of the main body 100 of the indoor unit of the air conditioner, the first air channel is a dirty air channel, and the second air channel is a fresh air channel.
The invention also provides an air-conditioning indoor unit, which comprises the connecting pipe structure.
According to the connecting pipe structure, the first pipe body and the second pipe body are designed into the sleeve structure, so that the problems that after-sale installation and punching are large in quantity, and the connecting pipe cannot be bent are solved.
The invention designs an air pipe assembly with two pipes in one hole, which is used for transmitting fresh air and dirty air, wherein a large pipe is a fresh air pipe, a small pipe is an exhaust pipe for separating the fresh air from the dirty air, and a sleeve structure is designed. A heat-insulating connecting pipe method for the total-heat fresh air conditioner is also designed, and the fresh air pipe is wrapped by a heat-insulating sleeve. In addition, the invention designs a pipe connecting method of a secondary heat exchange total-heat fresh air conditioner.
The sleeve pipe connecting component is connected with the indoor air conditioner and the outdoor rain cover component, and plays a role in conveying fresh air entering and dirty air discharging.
The sleeve union subassembly comprises insulation support, fresh air pipe, exhaust pipe, indoor joint (indoor joint part 30), foam joint (chucking part 50), a plurality of support frame, exhaust pipe sealing rubber circle. The exhaust pipe (first body 10) is the flexible hose that can stretch out and draw back to the steel wire of spiral is the skeleton, toughness such as outside parcel one deck PVC, and the material that mobility is good can be according to the demand extension or shorten. One end of the exhaust pipe in the room is connected by an indoor joint through screw threads, and in order to prevent exhaust air from leaking outside, a sealing rubber ring of the exhaust pipe is added at the bottom of the indoor joint before screw thread connection. Finally, the exhaust pipe and the indoor joint are sealed and fixed by glue to prevent the exhaust pipe from rotating. The outer loop of indoor joint passes through the fixed fresh air pipe of glue (second body 20), prevents that fresh air from spilling.
The heat preservation sleeve wraps up on circular blow molding pipe surface, has two effects:
firstly, the fresh air pipe (circular blowing pipe) is protected, the appearance is elegant, and the grade of the total-heat fresh air conditioner is increased. The fresh air pipe needs to penetrate through a wall hole, so that the fresh air pipe is easy to wear, and the fresh air pipe cannot be damaged by adding the heat-insulating sleeve;
secondly, the heat preservation effect, in chilly winter, the chilly new trend of follow introduction, indoor temperature is higher, does not wrap up the insulating sleeve, exposes indoor inner fresh air pipe surface and can produce the condensation water, drips the floor in the customer's house on, wraps up insulating sleeve fresh air pipe and can not produce the comdenstion water.
The fresh air pipe and the exhaust pipe are supported by a support ring 61, so that the exhaust pipe is centered. The two supporting parts 611 are butted and fixed on the exhaust pipe through the buckles, and the fixed supporting parts cannot rock back and forth on the exhaust pipe. The number of support rings is determined by the length of the fresh air duct.
The outdoor end of the sleeve structure pipe connecting component is connected with the rain cover component through threaded connection. The rain cover component consists of a rain cover, an outdoor air outlet box (a second air box), a fresh air box (a first air box), a fresh air pipe sealing rubber ring and an exhaust pipe sealing rubber ring.
The fresh air component is provided with an indoor fresh air inlet and an indoor air outlet. Indoor fresh air inlet draw-in groove is inserted through 2 joint buckles to indoor joint's outer loop, can press down when after sale dismantlement and connect the buckle to dismantle and press the position, easily deviate from.
The exhaust pipe of the pipe connecting component, the indoor exhaust outlet and the outdoor exhaust box form a dirty air channel, and the fresh air pipe of the pipe connecting component, the indoor fresh air inlet and the outdoor fresh air box form a fresh air channel.
The length of new tuber pipe is cut according to the thickness of wall body 130, and the one end of being connected with outdoor rain-proof cover subassembly can be cut, and the one end of being connected with indoor air conditioner can not cut.
When the connecting pipe component is installed on the wall, the angle of downward inclination is required to be kept between the connecting pipe component and the wall, and the indoor side of the hole is higher than the outdoor side of the hole, so that the rainwater is prevented from flowing backwards.
In the hot summer, the air temperature of fresh air pipe is very high, and dirty wind from indoor exhaust passes through from the exhaust pipe, and the temperature is very low, through the cooling of exhaust pipe, and the fresh air temperature that flows to total heat exchange core can reduce, plays the effect of heat transfer in advance. On the contrary, in chilly winter, cold air gets into the fresh air pipe, and the dirty wind that the temperature is high passes through the exhaust pipe, and cold air improves the problem of new trend through cold and hot exchange, then gets into indoor total heat exchange core.
By adopting the sleeve pipe structure, the pipe connecting component can realize the functions of introducing fresh air and discharging dirty air only by drilling a hole on the wall. Simultaneously when the installation use ripple blow molding new trend hose and exhaust pipe that can stretch out and draw back can the hose of bending, can reduce the area that the air conditioner occupy the house, make things convenient for after-sales installation and maintenance. The rain-proof cover assembly is matched with the pipe connecting part for use, so that rainwater cannot flow back indoors, and the purpose of rainwater backflow prevention is achieved. The heat-insulating sleeve of the connecting pipe component generates condensed water, and the sleeve of the fresh air pipe and the exhaust pipe are matched to play a role in secondary heat exchange.
In addition, the fresh air pipe can use a blow molding pipe or other form hoses with smooth inner wall and corrugated or threaded outer wall, and the smooth inner wall can reduce wind resistance and improve fresh air volume.
The large pipe of the connecting pipe part of the sleeve structure can be a fresh air pipe and can also be an exhaust pipe. The large pipe can adopt a flexible hose, and the bending capacity of the flexible hose is higher than that of the corrugated blow-molded pipe. The large pipe and the small pipe are simultaneously installed after sale by adopting the telescopic hoses without cutting, so that a client can extend and shorten according to the requirement, and the after-sale installation cost is reduced.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:
1. the problems of high cost and large punching quantity of after-sale installation punching are solved;
2. the problem that the connecting pipe cannot be bent is solved;
3. the problem of the heat exchange efficiency low is arranged in new trend, the air exhaust.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
