Description

Technical Field

[0001] The utility model relates to the technical field of passive house exhaust structures, and more specifically to an air intake and exhaust structure for a passive house in a construction project. Background Art

[0002] The air intake and exhaust structure is used in passive houses in construction projects mainly to reduce energy consumption and optimize air circulation while ensuring air quality, thereby maintaining a comfortable indoor climate environment. The design concept of passive houses in construction projects is to achieve a low-energy, high-comfort living and working environment through efficient building envelope structures and intelligent indoor environmental control systems. As an indispensable part of passive house design, the air intake and exhaust structure has the important function of maintaining indoor air quality and pressure balance. The following is a detailed analysis of its design and function.

[0003] In order to avoid the inlet and outlet air intercommunication, the existing passive house air intake and exhaust structure adds an L-shaped pipe structure, which makes the inlet and outlet air in opposite directions, thereby reducing the impact of the inlet and exhaust air. However, such a structure will cause the overall pipe structure to be extended, which reduces the overall support force of the pipe. Over a long period of time, the pipe connection end will be compressed and deformed, affecting the sealing of the connection. The reduction in sealing affects the quality of the fresh air fan ventilation. In view of this, we propose an air intake and exhaust structure for passive houses in construction projects. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide an air intake and exhaust structure for a passive house in a construction project to solve the technical problem that the increase of the current L-shaped pipe will lead to an increase in the gravity at the side end of the pipe, which will squeeze the pipe connection and deform under long-term action, affecting the sealing of the connection.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an air intake and exhaust structure for a passive house in a construction project, comprising a fresh air fan installed on a wall, wherein an outer air inlet and an outer air outlet of the fresh air fan are both installed with a first extension pipe penetrating the wall, an inner air inlet and an inner air outlet of the fresh air fan are both installed with a second extension pipe, the pipe openings of the two first extension pipes are both installed with first L-shaped pipes facing in opposite directions, and the pipe openings of the two second extension pipes are both installed with second L-shaped pipes facing in opposite directions, and a first bidirectional support member combined with the first L-shaped pipes is fixedly provided on one side of the wall close to the two first L-shaped pipes;

[0006] The first support member includes a support plate, and support blocks are fixedly provided on the upper and lower sides of the support plate. An elastic clamp combined with the support block is fixedly provided at one end of the support block close to the first L-shaped tube, and the opening diameter of the elastic clamp is smaller than the diameter of the first L-shaped tube.

[0007] The utility model can arrange the external air inlet and outlet of the fresh air fan on the outside of the wall by designing the first extension pipe, and the arrangement of the first L-shaped pipe does not affect the air intake and exhaust operations, and the first L-shaped pipe can improve the position stability under the limitation of the first two-way support member, thereby reducing the pressure on the first extension pipe, thereby maintaining a stable connection between the two and not easy to deform. Such structural coordination can maintain good connection sealing and reduce the impact on the ventilation of the fresh air fan.

[0008] Preferably, the elastic clamp comprises an elastic half ring, a wave groove is formed on one side of the elastic half ring close to the support block, and L-shaped pressing blocks are fixedly provided on the outer walls at both ends of the elastic half ring.

[0009] Preferably, a second bidirectional support is fixedly provided on one side of the fresh air fan close to the second extension tube, and the second bidirectional support is clamped and connected to the second extension tubes on both sides.

[0010] Preferably, bowl-shaped expansion pieces are fixedly provided at the pipe openings of the first L-shaped pipe and the second L-shaped pipe, and dust-proof pieces are fixedly provided on the outer edges of the expansion pieces on the first L-shaped pipe.

[0011] Preferably, a rain shield is installed on the top of the dustproof piece on the upper side, a threaded rod is fixed on the top of the dustproof piece, and a threaded hole combined with the threaded rod is opened on the top inner wall of the rain shield.

[0012] Preferably, a sealing ring is fixedly provided on the tube wall of the first extension tube and fits the outer edge of the tube opening of the first L-shaped tube, and a protective sleeve is fixedly provided on the outer wall of the first telescopic tube and fits the outer wall of the side end of the first L-shaped tube.

[0013] Preferably, a ring-shaped guide groove is provided on the outer wall of the first L-shaped tube close to the side end of the protective sleeve.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model can set the external air inlet and outlet of the fresh air fan on the outside of the wall by designing the first extension pipe. The setting of the first L-shaped pipe does not affect the air intake and exhaust work. The first L-shaped pipe can improve the position stability under the limitation of the first two-way support member, reduce the pressure on the first extension pipe, so that the connection between the two can be kept stable and not easy to deform. Such structural coordination can maintain good connection sealing and reduce the impact on the ventilation of the fresh air fan.

[0016] 2. The utility model can also quickly combine with or separate from the first L-shaped tube through an elastic clamp composed of an elastic semi-ring, a wave groove and an L-shaped pressure block. When the L-shaped pressure blocks on both sides are squeezed, the opening of the elastic semi-ring can be opened to expand the opening diameter. The setting of the wave groove can enhance the opening elasticity of the elastic semi-ring and facilitate the disassembly and assembly operation. The dustproof part arranged on the outer expansion part of the first L-shaped tube can reduce the entry of dust into the fresh air fan. At the same time, the rain shield arranged on the upper dustproof part can prevent rainwater from entering the fresh air fan when it rains, thereby reducing the impact of rainwater on the fresh air fan.
