Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioning circulation systems, specifically, it relates to an air conditioning circulating water pipe. Background Technology

[0002] Air conditioning circulating water piping is a core component of central air conditioning systems, enabling the transport and heat exchange of chilled and hot water. Its main function is to transport the chilled or hot water generated by the outdoor unit to the indoor terminal units, regulate the indoor temperature, and then return it to the outdoor unit, forming a stable circulation loop to ensure the efficient operation of the air conditioning system's cooling or heating functions. In practical applications, circulating water piping often needs to handle unexpected situations such as main pipe blockage or branch line closure. In these cases, a specific structure is required to enable rapid switching of the water flow, preventing overheating and damage to the outdoor unit due to water stagnation and ensuring continuous system operation.

[0003] However, current air conditioning circulating water pipe switching mostly relies on solenoid valve control. Solenoid valves are not only expensive to manufacture, but mechanical switching structures also have the defect of fixed diameter, which cannot adaptively adjust the size of the water flow channel according to water pressure changes. When the water pressure rises suddenly, water flow is easily obstructed, and it is still difficult to fully protect the outdoor unit of the air conditioner.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the current issue that air conditioning circulating water pipe switching relies heavily on solenoid valves, which are expensive to manufacture, and whose mechanical switching structures suffer from fixed diameters and inability to adaptively adjust the water flow channel size according to water pressure changes, leading to water flow obstruction during sudden pressure increases and insufficient protection for the outdoor unit, the basic concept of this utility model is as follows: An air conditioning circulating water pipeline includes a water tank and a four-way pipe. The water tank is connected to a main pipe, a drain pipe, a circulation pipe, and an airflow pipe. A four-way pipe is installed at the intersection of the main pipe, the drain pipe, the circulation pipe, and the airflow pipe. An adjustment mechanism for switching water paths is installed inside the four-way pipe. The adjustment mechanism includes a piston and a sliding rod.

[0006] In a preferred embodiment of this utility model, the main pipe and the drain pipe are coaxially arranged and horizontally, and the circulation pipe and the airflow pipe are coaxially arranged and vertically.

[0007] In a preferred embodiment of this utility model, the four-way pipe is provided with an installation groove and four sliding grooves. The installation groove is frustum-shaped and its inner diameter gradually increases from top to bottom. The piston is installed in the installation groove, and the four sliding rods are respectively slidably installed in the four sliding grooves.

[0008] In a preferred embodiment of this utility model, a guide rod is installed in the sliding groove, the sliding rod is slidably sleeved on the guide rod, and a spring is also installed in the sliding groove, the spring being movably sleeved on the guide rod.

[0009] In a preferred embodiment of this utility model, one end of the spring abuts against the bottom of the sliding groove, and the other end abuts against the bottom of the sliding rod, the end of which is connected to the piston.

[0010] In a preferred embodiment of this utility model, the water tank is also connected to an outlet pipe and an inlet pipe, and the drain pipe and outlet pipe are connected to the outdoor unit of the air conditioner through connecting pipes.

[0011] In a preferred embodiment of this utility model, the four-way pipe is connected to the main pipe, the drain pipe, the circulation pipe and the airflow pipe respectively. A water stop valve is installed at the end of the airflow pipe, and the other end of the main pipe is used to connect to the pipes inside the house.

[0012] In a preferred embodiment of this utility model, the mounting groove is coaxially arranged with the circulation pipeline of the four-way pipe, the four sliding grooves are evenly distributed along the circumference of the mounting groove, and all four sliding grooves are connected to the mounting groove.

[0013] Compared with the prior art, the present invention has the following advantages: This invention utilizes an adjustment mechanism consisting of a frustum-shaped mounting groove, a piston, a sliding rod, and a spring within a four-way pipe. This eliminates the need for a solenoid valve, reducing manufacturing costs. The inner diameter of the frustum-shaped mounting groove gradually increases from top to bottom. Combined with the structure of the spring and sliding rod, the size of the water flow channel is adaptively adjusted according to changes in water pressure after the main pipe becomes blocked. The greater the water pressure, the wider the channel opens, ensuring rapid and smooth water flow and preventing damage to the air conditioner's outdoor unit due to stagnant water.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0018] like Figures 1 to 5 As shown, an air conditioning circulating water pipeline includes a water tank 1 and a four-way pipe 2. The water tank 1 is connected to a main pipe 11, a drain pipe 12, a circulation pipe 15, and an airflow pipe 16. The four-way pipe 2 is installed at the intersection of the main pipe 11, drain pipe 12, circulation pipe 15, and airflow pipe 16. An adjustment mechanism 3 for switching water flow paths is installed inside the four-way pipe 2. The adjustment mechanism 3 includes a piston 33 and a sliding rod 34. In this configuration, the water tank 1 provides water storage and transfer space, and the four-way pipe 2 serves as the core for the convergence of all pipes. Working in conjunction with the piston 33 and sliding rod 34 of the adjustment mechanism 3, it guides and switches water flow paths under different operating conditions, ensuring that the water flows along a preset path.

[0019] like Figures 1 to 5 As shown, in a specific embodiment, the main pipe 11 and the drain pipe 12 are coaxially arranged and horizontally, while the circulation pipe 15 and the airflow pipe 16 are coaxially arranged and vertically. In this arrangement, the horizontally arranged main pipe 11 and drain pipe 12 facilitate the horizontal transmission of water flow between the indoor pipes and the four-way pipe 2, while the vertically arranged circulation pipe 15 and airflow pipe 16 are adapted to the vertical return of water flow and the vertical balance of air pressure, respectively. The orientation of the pipes optimizes the direction of water flow and the efficiency of air pressure circulation.

[0020] like Figures 1 to 5 As shown, further, the four-way pipe 2 has an installation groove 31 and four sliding grooves 32. The installation groove 31 is frustum-shaped, and its inner diameter gradually increases from top to bottom. The piston 33 is installed in the installation groove 31, and the four sliding rods 34 are respectively slidably installed in the four sliding grooves 32. In this configuration, the installation groove 31 provides installation and movement space for the piston 33, the frustum-shaped structure provides a basis for the adaptive adjustment of the water flow channel, and the sliding grooves 32 guide and limit the sliding rods 34, ensuring the stability of the movement of the piston 33 and the sliding rods 34.

[0021] like Figures 1 to 5As shown, a guide rod 35 is further installed in the sliding groove 32, and the sliding rod 34 is slidably sleeved on the guide rod 35. A spring 36 is also installed in the sliding groove 32, and the spring 36 is movably sleeved on the guide rod 35. In this configuration, the guide rod 35 provides guidance for the sliding of the sliding rod 34, preventing the sliding rod 34 from deviating. The spring 36 stores and releases elastic force through its own elastic deformation, providing power support for the reset of the sliding rod 34 and the sealing of the piston 33.

[0022] like Figures 1 to 5 As shown, one end of the spring 36 abuts against the bottom of the sliding groove 32, and the other end abuts against the bottom of the sliding rod 34, with the end of the sliding rod 34 connected to the piston 33. In this configuration, the spring 36 transmits its elastic force to the sliding rod 34 through the abutment relationship at both ends, and the sliding rod 34 then transmits the elastic force to the piston 33, achieving a stable fit of the piston 33 within the mounting groove 31, ensuring the passage is blocked under normal conditions and opened under emergency conditions.

[0023] like Figures 1 to 5 As shown, the water tank 1 is further connected to an outlet pipe 13 and an inlet pipe 14. The drain pipe 12 and the outlet pipe 13 are connected to the outdoor unit 4 of the air conditioner via a connecting pipe 5. In this configuration, the inlet pipe 14 is used to guide the return water flow from the indoor pipes into the water tank 1, while the outlet pipe 13 guides the water flow in the water tank 1 to the outdoor unit 4 of the air conditioner. The connecting pipe 5 serves as a transition channel to connect the drain pipe 12, the outlet pipe 13, and the outdoor unit 4 of the air conditioner.

[0024] like Figures 1 to 5 As shown, the four-way pipe 2 is further connected to the main pipe 11, drain pipe 12, circulation pipe 15, and airflow pipe 16, respectively. A stop valve is installed at the end of the airflow pipe 16, and the other end of the main pipe 11 is used to connect to the pipes inside the house. In this configuration, the four-way pipe 2 achieves centralized distribution of water flow and airflow through direct connection with each pipe. The stop valve prevents water from overflowing from the airflow pipe 16, and the main pipe 11 serves as the main channel for water to enter the room for heat exchange, ensuring the indoor temperature regulation needs.

[0025] like Figures 1 to 5 As shown, the mounting groove 31 is coaxially arranged with the circulation pipe 15 of the four-way pipe 2, and the four sliding grooves 32 are evenly distributed around the circumference of the mounting groove 31, and all four sliding grooves 32 are connected to the mounting groove 31. In this arrangement, the coaxiality between the mounting groove 31 and the circulation pipe 15 ensures that water flows into the circulation pipe 15 after the piston 33 moves down, and the even circumferential distribution of the sliding grooves 32 makes the force exerted by the sliding rod 34 on the piston 33 more balanced.

[0026] The implementation principle of an air conditioning circulating water pipeline in this embodiment is as follows: Under normal operating conditions, the water output from the outdoor unit 4 of the air conditioner flows into the drain pipe 12 through the connecting pipe 5, and then into the four-way pipe 2. At this time, the spring 36 in the sliding groove 32 pushes the sliding rod 34 through its own pre-tightening force, so that the piston 33 is attached to the upper part of the frustum-shaped mounting groove 31, blocking the passage of the circulating pipeline 15. The water flows from the four-way pipe 2 into the main pipe 11. After completing the heat exchange through the pipes in the house, it flows back to the water tank 1 through the inlet pipe 14, and then flows back to the outdoor unit 4 of the air conditioner through the outlet pipe 13 and the connecting pipe 5, forming a complete main circulation. The airflow pipe 16, together with the water stop valve, is used to balance the air pressure in the four-way pipe 2 and the water tank 1 to ensure smooth water flow.

[0027] When the main pipe 11 is blocked or closed, the water pressure in the drain pipe 12 increases. The water pressure acts on the lower surface of the piston 33, pushing the piston 33 to move downward along the frustum-shaped mounting groove 31. Since the mounting groove 31 has a frustum-shaped structure with an inner diameter that gradually increases from top to bottom, the greater the water pressure, the farther the piston 33 moves downward, and the larger the water flow channel formed between the inner wall of the mounting groove 31 and the piston 33. When the piston 33 moves downward, it drives the sliding rod 34 to slide along the guide rod 35 and compress the spring 36. The water flows into the circulation pipe 15 through the gradually expanding channel and finally flows into the water tank 1. Then, it flows back to the air conditioner outdoor unit 4 through the outlet pipe 13 and the connecting pipe 5, preventing the air conditioner outdoor unit 4 from being damaged due to water stagnation. If water accidentally flows into the airflow pipe 16, the stop valve at its end will prevent the water from flowing out.
