Description

Technical Field

[0001] This utility model belongs to the field of air conditioning control technology and relates to an air conditioning control device with a solenoid valve assembly. Background Technology

[0002] In modern air conditioning equipment and refrigeration systems, precise airflow control is typically required to meet the varying temperature, humidity, and air quality needs of different areas. Traditional dampers, as key components for opening and closing airflow channels, are motor-controlled and widely used in these systems. However, when faced with complex structures with multiple airflow channels, the limitations of traditional damper designs become increasingly apparent.

[0003] For a single airflow channel, using a single damper to open, close, or regulate airflow is a relatively simple and direct solution. However, when multiple airflow channels are involved, continuing to use a separate damper for each channel significantly increases the complexity of the entire system. This not only increases manufacturing costs but is also difficult to implement due to limited installation space. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an air conditioning control device with a solenoid valve assembly.

[0005] The objective of this utility model can be achieved through the following technical solution: an air conditioning control device with a solenoid valve assembly, comprising:

[0006] The housing is provided with an air inlet channel, a transition cavity and an air outlet channel. The number of air outlet channels is at least two. The number of transition cavities is the same as the number of air outlet channels and they are arranged in a one-to-one correspondence. Each air outlet channel is connected to each of the transition cavities. The transition cavity and the air inlet channel are connected through a branch hole.

[0007] The number of solenoid valves is the same as the number of transition chambers and they are arranged in a one-to-one correspondence. Each solenoid valve is installed in the transition chamber and is connected to a movable sealing block.

[0008] The travel positions of the blocking block include a blocking position and an open position; when the blocking block is in the blocking position, the blocking block blocks the opening connecting the branch hole and the air inlet channel; when the blocking block is in the open position, the air outlet channel and the air inlet channel are connected through the transition cavity.

[0009] Preferably, the air inlet channel and each of the air outlet channels extend along a first direction, and the transition cavity and the branch hole extend along a second direction, wherein the first direction and the second direction are perpendicular.

[0010] Preferably, the branch hole is connected to the center of the transition cavity in the radial direction, and the air outlet channel is connected to the end of the transition cavity in the radial direction.

[0011] Preferably, the cross-section at the intersection of the air outlet channel and the transition cavity is configured as an arc-shaped notch structure.

[0012] Preferably, the number of transition cavities is at least four, and each transition cavity is divided into two rows and distributed on both sides of the air inlet channel.

[0013] Preferably, the air inlet channel and each of the air outlet channels are configured as blind holes, and the openings of the air inlet channel and each of the air outlet channels are located on one end face of the housing.

[0014] Preferably, a spring is provided between the solenoid valve and the sealing block, and the spring applies a spring force to the sealing block to make it tend toward the sealing position.

[0015] Preferably, the pull rod of the solenoid valve is fixedly connected to the blocking block. When the solenoid valve is energized, the solenoid valve applies a pulling force to the blocking block through the pull rod, causing it to tend towards the open position.

[0016] Preferably, the housing is also connected to a mounting bracket.

[0017] Preferably, the mounting bracket is provided with at least two mounting holes.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Based on the structure of one air inlet channel corresponding to multiple air outlet channels, the opening and closing of each branch hole is independently controlled by the solenoid valve set between each transition chamber, thereby controlling the opening and closing of each air outlet channel, which greatly reduces the complexity of the system.

[0020] 2. By extending the air inlet and outlet channels along the first direction, the air inlet and outlet channels, as well as the individual outlet channels, are arranged in parallel, ensuring their axial alignment. This design allows for more efficient use of internal space, accommodating more outlet channels within a limited area while ensuring each outlet channel has an independent transition chamber for airflow control, guaranteeing precise and independent airflow distribution. Furthermore, the alignment of the air inlet and outlet channels in the same direction makes the airflow path more direct, reducing unnecessary bends or turns. The transition chambers and branch holes extend along the second direction. By making the first and second directions perpendicular to each other, three-dimensional space can be effectively utilized, optimizing the device's size and layout. This perpendicular cross-design allows for easier installation and maintenance of the solenoid valves and sealing blocks, avoiding interference with the air inlet and outlet channels and fully utilizing the housing space.

[0021] 3. When the solenoid valve is de-energized, the spring applies a continuous force to the sealing block, keeping it in the sealed position and thus closing the branch orifice. This means that when the system is de-energized or the solenoid valve is not activated, the air outlet is closed by default. When it is necessary to open an air outlet, the corresponding solenoid valve is energized and generates magnetic force, overcoming the spring force to pull the sealing block to the open position, thereby opening the branch orifice and allowing airflow.

Detailed Implementation

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figures 1 to 6 As shown, an air conditioning control device with a solenoid valve assembly includes: a housing 100, which is provided with an air inlet channel 110, a transition cavity 120, and an air outlet channel 130. The number of air outlet channels 130 is at least two. The number of transition cavities 120 is the same as the number of air outlet channels 130 and they are arranged in a one-to-one correspondence. Each air outlet channel 130 is connected to each transition cavity 120. The transition cavity 120 is connected to the air inlet channel 110 through a branch hole 140. A solenoid valve 200 is also included. The number of solenoid valves 200 is the same as the number of transition chambers 120 and they are set one-to-one. Each solenoid valve 200 is installed in the transition chamber 120. The solenoid valve 200 is connected to a movable blocking block 210. The stroke position of the blocking block 210 includes a blocking position and an open position. When the blocking block 210 is in the blocking position, the blocking block 210 blocks the opening connecting the branch hole 140 and the air inlet channel 110. When the blocking block 210 is in the open position, the air outlet channel 130 and the air inlet channel 110 are connected through the transition chamber 120.

[0031] The air inlet channel 110 is the path for airflow (cold or hot air) to enter the device. The transition cavity 120 is independently set and acts as a transition between the air inlet channel 110 and the air outlet channel 130. That is, the airflow in the air inlet channel 110 can only enter the air outlet channel 130 after passing through the transition cavity 120. Each transition cavity 120 corresponds to one air outlet channel 130, meaning each transition cavity 120 controls the opening and closing of the corresponding air outlet channel 130. There are at least two air outlet channels 130, which are used to transport the airflow. In this design, the airflow in the air inlet channel 110 can enter the air outlet channel 130 through the transition cavity 120 and then be output. That is, the air inlet channel 110-branch hole 140-transition cavity 120-air outlet channel 130 forms an airflow transport path. By controlling the opening and closing of the branch hole 140 and the transition cavity 120, the opening and closing of the corresponding air outlet channel 130 can be achieved.

[0032] Each transition chamber 120 is equipped with a solenoid valve 200. The number of solenoid valves 200 is equal to the number of air outlet channels 130 (and the corresponding transition chambers 120). Each solenoid valve 200 is connected to a blocking block 210, which can move between a blocked position and an open position. When the blocking block 210 is in this position, it completely blocks the opening where the branch hole 140 meets the air inlet channel 110, thereby preventing airflow from entering the corresponding transition chamber 120 and the air outlet channel 130. When the blocking block 210 moves to this position, it separates from the opening of the branch hole 140, allowing the air inlet channel 110 to connect with the air outlet channel 130 through the transition chamber 120.

[0033] In actual use, when a specific air outlet 130 needs to be opened, the corresponding solenoid valve 200 is energized, causing the sealing block 210 to be in the open position. If a certain air outlet is to be closed, the solenoid valve 200 is de-energized, and the sealing block 210 moves to the sealing position. By controlling which solenoid valves 200 are active, the opening and closing of different air outlets in the air conditioning system can be flexibly controlled, thereby controlling the state of each air outlet 130.

[0034] This solution improves control efficiency and reduces complexity by simplifying the system structure. In traditional air conditioning airflow control systems, achieving independent control of multiple air outlets may require complex mechanical structures or multiple independent controllers, increasing system complexity and cost. Since each air outlet duct 130 is directly controlled by its own solenoid valve 200, no additional mechanical linkages or other complex linkage mechanisms are needed. Therefore, the overall system physical design is simpler, and each air outlet duct 130 can be controlled individually. This means that airflow can be precisely adjusted according to the needs of different areas, providing a better user experience and energy efficiency management. The solenoid valve 200 has a fast operating speed, quickly responding to changes in control signals and rapidly adjusting airflow, improving the system's responsiveness. The reduced number of moving parts reduces potential failure points and makes maintenance more convenient and faster.

[0035] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, based on the above embodiment, the air inlet channel 110 and each air outlet channel 130 extend along the first direction, and the transition cavity 120 and the branch hole 140 extend along the second direction. The first direction and the second direction are perpendicular.

[0036] By extending the air inlet channel 110 and the air outlet channel 130 along the first direction, it means that the air inlet channel 110 and the air outlet channel 130, as well as each air outlet channel 130, are arranged in parallel, making the axial directions of the air inlet channel 110 and the air outlet channel 130 consistent. This design can make more efficient use of internal space, accommodating more air outlet channels 130 within a limited space, while ensuring that each air outlet channel 130 has an independent transition cavity 120 for airflow control, ensuring the accuracy and independence of airflow distribution. Furthermore, the air inlet channel 110 and the air outlet channel 130 are arranged in the same direction, making the airflow path more direct and reducing unnecessary bends or turns.

[0037] Both the transition cavity 120 and the branch hole 140 extend along the second direction. By making the first and second directions perpendicular to each other, three-dimensional space can be effectively utilized, optimizing the size and layout of the device. This perpendicularly intersecting design allows the solenoid valve 200 and the sealing block 210 to be installed and maintained more easily, and avoids interference with the air inlet channel 110 and the air outlet channel 130, making full use of the space in the housing 100.

[0038] Based on the above implementation, the branch hole 140 is connected to the center position of the transition cavity 120 in the radial direction, and the air outlet channel 130 is connected to the end position of the transition cavity 120 in the radial direction.

[0039] The branch hole 140 and the air outlet 130 are connected to the transition cavity 120 at different radial positions. The main purpose of this design is to avoid interference between the branch hole 140 and the air outlet 130. In addition, since the branch hole 140 is connected to the center of the transition cavity 120 in the radial direction, the sealing block 210 can act precisely at the center of the transition cavity 120, thereby better sealing or opening the opening of the branch hole 140.

[0040] In the actual structure, each transition cavity 120 is actually located at the same horizontal height, while the air outlet duct 130 passes through the upper or lower part of the transition cavity 120. This design allows multiple air outlet ducts 130 to be located at different heights, and by communicating with the upper or lower part of the transition cavity 120, interference between the various air outlet ducts 130 is avoided.

[0041] Based on the above embodiment, the cross-section at the intersection of the air outlet channel 130 and the transition cavity 120 is configured as an arc-shaped notch structure. The arc-shaped notch structure allows airflow to enter the air outlet channel 130 evenly.

[0042] Based on the above embodiment, the number of transition cavities 120 is at least four, with each transition cavity 120 arranged in two rows and distributed on both sides of the air inlet channel 110. This design of dividing the transition cavities 120 into two rows and distributing them on both sides of the air inlet channel 110 allows for more efficient use of the space within the housing 100. This symmetrical layout makes the device more compact, and symmetrical structures generally mean simpler mold designs.

[0043] In the actual structure, there are four air outlet channels 130 and four transition cavities 120. The air outlet channels 130 and transition cavities 120 are arranged in two rows on both sides of the air inlet channel 110. The two transition cavities 120 in the same row are at the same height, and the two air outlet channels 130 in the same row are arranged vertically in a vertically corresponding manner. In the two air outlet channels 130 in the same row, one is connected to the upper radial end of one transition cavity 120, and the other is connected to the lower radial end of another transition cavity 120. By arranging the two air outlet channels 130 in the same row in a staggered vertical layout, they can each connect to the two transition cavities 120 located at the same height. This design avoids interference between the two air outlet channels 130 in the same row.

[0044] In the actual structure, the air inlet channel 110 and each air outlet channel 130 are both set as blind hole structures, and the opening of the air inlet channel 110 and the opening of each air outlet channel 130 are located on one end face of the housing 100.

[0045] like Figure 1 , Figure 3 As shown, based on the above embodiment, a spring 220 is provided between the solenoid valve 200 and the blocking block 210, and the spring 220 applies a spring force to the blocking block 210 to make it tend to the blocking position.

[0046] When the solenoid valve 200 is de-energized, the spring 220 applies a continuous force to the sealing block 210, keeping it in the sealed position and thus closing the branch port 140. This means that when the system is de-energized or the solenoid valve 200 is not activated, the air outlet duct 130 is closed by default. When it is necessary to open an air outlet duct 130, the corresponding solenoid valve 200 is energized and generates magnetic force, which overcomes the elastic force of the spring 220 and pulls the sealing block 210 to the open position, thereby opening the branch port 140 and allowing airflow.

[0047] In addition, the function of spring 220 can reduce the workload of the coil of solenoid valve 200, because it only needs to overcome the resistance of spring 220 instead of relying entirely on its own strength to move the sealing block 210, thereby reducing the wear of mechanical parts.

[0048] Based on the above implementation method, the pull rod of the solenoid valve 200 is fixedly connected to the blocking block 210. When the solenoid valve 200 is energized, the solenoid valve 200 applies a pulling force to the blocking block 210 through the pull rod, causing it to tend to open.

[0049] The fixed connection between the pull rod and the sealing block 210 allows the solenoid valve 200 to directly control the action of the sealing block 210, reducing intermediate links and improving the system's response speed and control accuracy.

[0050] like Figure 1 As shown, based on the above embodiment, a mounting bracket 300 is also included, and the housing 100 is connected to the mounting bracket 300. The housing 100 can be mounted via the mounting bracket 300, thereby installing the housing 100 at a corresponding position in the air conditioning system.

[0051] Preferably, the mounting bracket 300 is provided with at least two mounting holes 310.

[0052] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0053] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0055] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
