Description

Technical Field

[0001] This utility model relates to the field of controller structure. More specifically, this utility model relates to a controller for a constant temperature and humidity system. Background Technology

[0002] Currently, constant temperature and humidity systems are installed indoors to provide a comfortable living or working environment. A constant temperature and humidity environment improves human comfort and is beneficial to health. A constant temperature and humidity system typically includes: refrigeration equipment, heating equipment, dehumidification equipment, humidification equipment, temperature sensors, humidity sensors, and a controller for temperature and humidity regulation. The controller allows users to view indoor temperature and humidity or input desired parameters to adjust them. The controller usually consists of a housing, a PCB board inside the housing, and a touchscreen on the housing. The housing has multiple communication interfaces, and the PCB board integrates various modules. The touchscreen allows users to view or adjust relevant parameters to meet their living or working needs. However, existing controllers for constant temperature and humidity systems are susceptible to moisture intrusion in high-humidity environments, which can adversely affect the PCB board inside the housing. To address this issue, various moisture-proofing methods have been researched, such as placing desiccant granules inside the controller (e.g., a PLC controller disclosed in patent application number 202223106215.0) to absorb moisture entering the controller housing. However, once the desiccant granules are saturated with water, they lose their drying effect and need to be replaced with new desiccant granules. In the aforementioned controller structure, replacing the desiccant granules requires disassembling the entire controller structure and replacing the desiccant pack, which is cumbersome and inconvenient to use. Utility Model Content

[0003] One objective of this invention is to solve at least the aforementioned problems and to provide a constant temperature and humidity system controller that facilitates the replacement of desiccant granules and is easy to use.

[0004] To achieve these objectives and other advantages according to this utility model, a constant temperature and humidity system controller is provided, including a housing and a PCB board. The housing is provided with a partition plate to divide it into an operating area and a collection area arranged sequentially from top to bottom. The PCB board is disposed within the operating area. A filling hole is provided at one end of the top of the housing along its width direction, and a sealing cap is movably mounted on the filling hole. A passage hole is provided on the partition plate along the width direction of the housing. The system also includes:

[0005] A dehumidifier box is vertically slidably inserted into the passage hole. The top of the dehumidifier box is open and the bottom has an outlet. The dehumidifier box contains desiccant particles.

[0006] A blocking ball is installed inside the dehumidification box and corresponds to the outlet. A vertical rod is provided at the bottom of the blocking ball. The end of the vertical rod away from the blocking ball passes through the outlet and the passage hole in sequence and is connected to the bottom wall of the collection area.

[0007] A support spring is vertically installed at the bottom of the dehumidification box, with one end of the support spring away from the dehumidification box connected to the bottom wall of the collection area. When the support spring is in its natural state, the lower part of the sealing ball blocks the outlet, and the top of the dehumidification box extends into the adding hole and the bottom is located in the passage hole. When an external force presses down on the dehumidification box, the dehumidification box slides along the passage hole, thereby causing the sealing ball to open the outlet.

[0008] Preferably, the housing has an air inlet on the outer wall near the dehumidification box, the air inlet is located on one side of the dehumidification box, the operating area has a cooling fan located on the side of the dehumidification box away from the air inlet, and the operating area has an air outlet on the side wall away from the air inlet.

[0009] Preferably, the dehumidification box is attached to the inner wall of the shell along both side walls in the width direction of the shell.

[0010] Preferably, the dehumidification chamber is provided with a pair of inclined guide plates, the upper end of the guide plates being connected to the inner side wall of the dehumidification chamber, the lower end being connected to the inner bottom wall of the dehumidification chamber, and the lower end being tangent to the outlet.

[0011] Preferably, the support springs are a pair, with the pair of support springs located at both ends of the bottom of the dehumidifier box along its length.

[0012] Preferably, the top of the dehumidification box is provided with a cover plate.

[0013] Preferably, the dehumidification box is transparent, and transparent windows are provided on the side walls of both the collection area and the operation area.

[0014] This utility model has at least the following beneficial effects:

[0015] By configuring a housing, PCB board, partition plate, operating area, collection area, adding hole, sealing cover, passage hole, dehumidification box, desiccant granules, sealing ball, vertical rod, and support spring, in the initial state, desiccant granules are added to the dehumidification box through the adding hole, and the sealing cover is closed. The dehumidification box dehumidifies normally. At this time, under the action of the support spring, the sealing ball blocks the outlet. When it is necessary to replace the desiccant granules, the sealing cover is opened, and downward pressure is applied to the dehumidification box. During the downward sliding of the dehumidification box, the outlet moves away from the sealing ball, and the outlet opens. The desiccant granules enter the collection area through the outlet and passage hole. When no more desiccant granules flow out of the dehumidification box, the pressure applied to the dehumidification box is released. At this time, the sealing ball, under the action of the support spring, re-seals the outlet. Then, new desiccant granules are added to the dehumidification box, and the sealing cover is closed again. The dehumidification box resumes its dehumidification function. Overall, compared with the existing technology, it is not necessary to disassemble the controller to replace the desiccant granules, making desiccant replacement more convenient and easier to use.

[0016] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0023] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0024] like Figure 1-4 As shown, this utility model provides a constant temperature and humidity system controller, including a housing 1 and a PCB board. The housing 1 is provided with a partition plate 2 to divide the housing 1 into an operating area and a collection area arranged sequentially from top to bottom. The PCB board is disposed in the operating area. A filling hole is provided at one end of the top of the housing 1 along its width direction, and a sealing cover 3 is movably disposed on the filling hole. A passage hole is provided on the partition plate 2 along the width direction of the housing 1. The system also includes:

[0025] The dehumidification box 4 is vertically slidably inserted into the passage hole. The top of the dehumidification box 4 is open and the bottom has an outlet. The dehumidification box 4 contains desiccant particles 7.

[0026] A blocking ball 11 is disposed inside the dehumidification box 4 and corresponds to the outlet. A vertical rod 10 is provided at the bottom of the blocking ball 11. The end of the vertical rod 10 away from the blocking ball 11 passes through the outlet and the passage hole in sequence and is connected to the bottom wall of the collection area.

[0027] A support spring 9 is vertically installed at the bottom of the dehumidification box 4, with one end of the support spring 9 away from the dehumidification box 4 connected to the bottom wall of the collection area. When the support spring 9 is in its natural state, the lower part of the sealing ball 11 blocks the outlet, and the top of the dehumidification box 4 extends into the adding hole and the bottom is located in the passage hole. When an external force presses down on the dehumidification box 4, the dehumidification box 4 slides along the passage hole, thereby causing the sealing ball 11 to open the outlet.

[0028] In the above technical solution, the housing 1 is a square structure, and a PCB board (not shown in the figure) is provided inside it; a partition plate 2 is horizontally provided inside the housing 1 to divide the housing 1 into an upper operating area and a lower collection area. A movable door (not shown in the figure) is installed on the side wall of the collection area. An adding hole is opened at the top of the operating area, and a sealing cover 3 is matched with the adding hole. The sealing cover 3 is provided with a handle 13 for lifting the sealing cover 3. The adding hole is arranged along the width direction of the housing 1. A passage hole is opened on the partition plate 2, and the passage hole is connected to the... Corresponding to the added holes, the passage holes are also arranged along the width direction of the housing 1. A dehumidification chamber 4 is also provided inside the housing 1, containing desiccant particles 7. The desiccant particles 7 can be water-absorbing and color-changing silica gel particles (commonly used in laboratories). The length direction of the dehumidification chamber 4 is consistent with the width direction of the housing 1. Multiple air guide holes 15 are evenly distributed on both side walls of the dehumidification chamber 4 along its width direction (also along the length direction of the housing 1). The diameter of the air guide holes 15 is smaller than the diameter of the desiccant particles 7, for example, it can be 0.5~1mm smaller, to ensure the air can enter the dehumidification chamber. Air can pass through the dehumidifier box 5 while preventing desiccant particles 7 from leaking out of the dehumidifier box 4. The dehumidifier box 4 is vertically slidably inserted into the passage hole, allowing it to slide vertically along the passage hole. A support spring 9 is provided at the bottom of the dehumidifier box 4, with its other end connected to the inner bottom wall of the collection area to provide support. The dehumidifier box 4 has an open top and an outlet at the bottom. A sealing ball 11 is provided inside the dehumidifier box 4, with a vertical rod 10 at its bottom. The diameter of the vertical rod 10 is smaller than the diameter of the outlet. The end of the vertical rod 10 away from the blocking ball 11 passes through the outlet and connects to the inner bottom wall of the collection area. In this way, when the support spring 9 is in its natural state, the lower part of the blocking ball 11 blocks the outlet under the action of the support spring 9, and the top of the dehumidification box 4 extends into the adding hole and the bottom is located in the passage hole. The dehumidification box 4 dehumidifies the air entering the housing 1. When the sealing cover 3 is opened, the top of the dehumidification box 4 communicates with the outside. At this time, the external force presses the top of the dehumidification box 4, and the dehumidification box 4 slides along the passage hole, thereby causing the dehumidification box 4 to move relative to the blocking ball 11, thereby opening the outlet.

[0029] In this technical solution, during initial use, desiccant granules 7 are added to the dehumidifier box 4 through the adding hole, and the sealing cover 3 is closed (the sealing cover 3 does not contact the dehumidifier box 4 in its natural state after being closed). Under the action of the support spring 9, the sealing ball 11 blocks the outlet. At this time, the dehumidifier box 4 dehumidifies normally. When it is necessary to replace the desiccant granules 7, the sealing cover 3 is opened, and a downward pressing force is applied to the dehumidifier box 4. As the dehumidifier box 4 slides downward, it drives the outlet to move away from the sealing ball 11, thereby sealing it. Ball 11 moves away from the outlet to open it. At this time, desiccant particles 7 enter the collection area through the outlet and passage hole. When desiccant particles 7 no longer flow out of the dehumidification box 4, the pressure applied to the dehumidification box 4 is released. At this time, under the action of the support spring 9, the sealing ball 11 re-seals the outlet. Then, new desiccant particles 7 are added to the dehumidification box 4, and the sealing cover 3 is sealed again. The dehumidification box 4 resumes its dehumidification function. When the desiccant particles 7 in the collection area accumulate to a certain amount, the desiccant particles 7 can be taken out, dried once, and reused.

[0030] The beneficial effects of adopting this technical solution are that by setting up a housing 1, PCB board, partition plate 2, operation area, collection area, adding hole, sealing cover 3, passage hole, dehumidification box 4, desiccant granules 7, sealing ball 11, vertical rod 10, and support spring 9, a moisture-proof controller structure is provided. Compared with the existing technology, it is not necessary to disassemble the controller to replace the desiccant granules 7, which is more convenient in terms of desiccant replacement, and it is very convenient to use and has strong practicality.

[0031] In another technical solution, the housing 1 is provided with an air inlet 5 on the outer wall near the dehumidification box 4, the air inlet 5 is located on one side of the dehumidification box 4, a cooling fan 8 is provided in the operating area, the cooling fan 8 is located on the side of the dehumidification box 4 away from the air inlet 5, and an air outlet 14 is provided on the side wall of the operating area away from the air inlet 5.

[0032] In this technical solution, the air inlet 5 is provided on the side wall of the housing 1 where the operating area is located. The air inlet 5 is located on the side wall of the housing 1 near the dehumidification box 4. There can be multiple air inlets 5, which are arranged alternately from top to bottom. The cooling fan 8 is installed on the inner wall of the operating area and is located in the dehumidification box 4 away from the air inlet 5. That is, the dehumidification box 4 is located between the cooling fan 8 and the air inlet 5. The end of the cooling fan 8 away from its own motor faces the dehumidification box 4. The parameters of the cooling fan 8 can be set as follows: rated power can be set to 5W, maximum air volume can be set to 0.5m³ / min, and air pressure can be set to 50~80Pa, so as to force air... Air enters the operating area through the air inlet 5, passes sequentially through the air guide hole 15 on the dehumidification box 4 near the air inlet 5, the desiccant particles 7, and the air guide hole 15 on the other side wall of the dehumidification box 4, and is finally discharged through the air outlet 14. The diameter of the air guide holes can be designed to be 1mm, and the spacing between the holes can be designed to be 5mm, arranged in an alternating pattern to ensure that the air passes evenly through the desiccant layer and avoids particle leakage. Through the negative pressure of the cooling fan 8, the air flow path is limited to: air inlet 5 → air guide hole 15 (near the side of air inlet 5) → desiccant particle 7 layer → air guide hole 15 (near the side of cooling fan 8) → air outlet 14, forming a forced convection channel. This ensures that the air entering the housing 1 passes through the dehumidification box 4 to achieve the purpose of dehumidification.

[0033] In this technical solution, when in use, the cooling fan 8 is started, generating suction on the side near the dehumidification box 4, thereby causing outside air to enter the operating area through the air inlet 5. Then the air passes through the air guide hole 15 on the side wall of the dehumidification box 4 near the air inlet 5, the desiccant particles 7, and the air guide hole 15 on the side wall of the dehumidification box 4 near the cooling fan 8, and finally flows out from the air outlet 14.

[0034] The beneficial effect of adopting this technical solution is that by designing the air inlet 5, the cooling fan 8, and the air outlet 14, a heat dissipation and moisture-proof structure is provided, which can dehumidify the air entering the housing 1, and at the same time remove the hot air inside the housing 1, thus avoiding damage to the PCB board inside the controller due to high temperature.

[0035] In another technical solution, the dehumidification box 4 is attached to the inner wall of the housing 1 along both side walls along the width direction of the housing 1; specifically, the passage hole is elongated, and the length direction of the passage hole is consistent with the width direction of the housing 1. The two ends of the passage hole are open along its length direction, that is, the length of the passage hole is consistent with the width of the operating area. The open ends of the passage hole are directly connected to the inner wall of the housing 1, so that the two side walls of the dehumidification box 4 along the width direction of the housing 1 are attached to the corresponding inner side walls of the housing 1, so that the dehumidification box 4 has a function similar to a partition. The dehumidification box 4 divides the operating area into an installation area and a processing area (e.g., from left to right) arranged sequentially. Figure 1(As shown from left to right), a cooling fan 8 is installed in the installation area, and the air inlet 5 is provided on the side wall of the processing area. This can dehumidify the air entering the housing 1 through the air inlet 5 as much as possible, which is highly practical.

[0036] In another technical solution, the dehumidification chamber 4 is provided with a pair of inclined guide plates 12. The high end of the guide plates 12 is connected to the inner side wall of the dehumidification chamber 4, and the low end is connected to the inner bottom wall of the dehumidification chamber 4 and is tangent to the outlet. Specifically, as shown in the figure, the pair of guide plates 12 are respectively arranged on both sides of the outlet. The guide plates 12 and the inner wall of the shell 1 form a funnel-like shape. The inclination angle of the guide plates 12 can be 45~60 degrees (angle with the horizontal plane). Its low end is tangent to the inner wall of the outlet, ensuring that the desiccant particles are swept towards the outlet along the guide plates under the action of gravity, avoiding particle accumulation. The beneficial effect of adopting this technical solution is that by designing the guide plates 12, it is convenient to guide the desiccant particles 7 to the outlet, which facilitates rapid discharge.

[0037] In another technical solution, the support springs 9 are a pair, and the pair of support springs 9 are respectively located at both ends of the bottom of the dehumidification box 4 along its length direction; the beneficial effect of adopting this technical solution is that by designing a pair of support springs 9, the bottom of the dehumidification box 4 is subjected to uniform force, thereby improving the support effect and the pressing effect.

[0038] In another technical solution, a cover plate is movably provided on the top of the dehumidification box 4; specifically, the cover plate is placed on the top of the dehumidification box 4. When it is necessary to replace the desiccant granules 7, the cover plate is placed on the top of the dehumidification box 4, so that it is convenient for people to manually apply pressure to the cover plate and then press the dehumidification box 4 through the cover plate, which is convenient for operation.

[0039] In another technical solution, the dehumidification box 4 is transparent, and transparent windows (not shown in the figure) are provided on the side walls of the collection area and the operation area. Specifically, the desiccant particles 7 are water-absorbing and color-changing silica gel particles. The transparent window on the operation area is used to observe the degree of water absorption of the desiccant particles 7 in the dehumidification box 4, and the transparent window on the collection area is used to observe the amount of desiccant particles 7 collected in the collection area. When there is too much, the desiccant particles 7 in the collection area can be taken out, dried, and reused.

[0040] This utility model provides a constant temperature and humidity system controller, including a housing 1, a PCB board, and a touch screen 6 connected to the PCB board. The housing 1 has a partition plate 2 to divide it into an operating area and a collection area arranged sequentially from top to bottom. The PCB board is located in the operating area, and the touch screen 6 is embedded in the outer wall of the housing 1 where the operating area is located. The top of the housing 1 has an addition hole arranged along the width direction of the housing 1, and a sealing cover 3 is movably mounted on the addition hole. The partition plate 2 has a passage hole located directly below the addition hole and arranged along the width direction of the housing 1. The system also includes:

[0041] The dehumidification box 4 is vertically slidably disposed at one end within the operating area. The top of the dehumidification box 4 is open and the bottom has an outlet. The dehumidification box 4 contains desiccant particles 7.

[0042] A blocking ball 11 is disposed inside the dehumidification box 4 and corresponds to the outlet. A vertical rod 10 is provided at the bottom of the blocking ball 11. The end of the vertical rod 10 away from the blocking ball 11 passes through the outlet and the passage hole and is connected to the bottom wall of the collection area.

[0043] A support spring 9 is vertically installed at the bottom of the dehumidification box 4. One end of the support spring 9 away from the dehumidification box 4 passes through the passage hole and connects to the bottom wall of the collection area. When the support spring 9 is in its natural state, the lower part of the sealing ball 11 blocks the outlet, and the top of the dehumidification box 4 extends into the adding hole and the bottom is located in the sliding hole. When an external force presses down on the dehumidification box 4, the dehumidification box 4 slides along the passage hole, thereby driving the sealing ball 11 to open the outlet.

[0044] In the above technical solutions, the constant temperature and humidity system and its control method are existing. For example, patent application number 202110677487.7 discloses a control method, controller and constant temperature and humidity system for a constant temperature and humidity system. In actual use, the controller can also be designed according to the required adaptability of the constant temperature and humidity system. For example, the PCB board can refer to the following design:

[0045] The PCB board integrates a power module, a Modbus communication module, a BACnet communication module, an MCU module (microcontroller), a message import interface (i.e., a USB interface), and electrical control interfaces for water valves and water pumps.

[0046] The power module, Modbus communication module, BACnet communication module, USB interface, and electrical control interfaces for water valve and water pump are all connected to the MCU module.

[0047] The system connects to the controlled devices (heating and cooling devices, or indoor temperature and humidity sensors using the Modbus protocol) via a Modbus interface to read Modbus data and transmit it to the MCU module. The MCU module then controls the heating and cooling devices to regulate the indoor temperature based on the received data. The system also imports Excel-formatted Modbus messages into the touchscreen via a USB interface for user viewing. Furthermore, the system connects to the controlled devices (humidifiers / dehumidifiers, such as fresh air systems with humidity control) via a BACnet interface, allowing the MCU module to regulate the indoor humidity. Finally, the system connects to the controlled devices (water valves and pumps on the heating / cooling devices, humidifiers, and dehumidifiers) via electrical control interfaces for MCU module control.

[0048] Furthermore, a networking interface can be integrated on the PCB board. The networking interface is connected to the MCU module and is used to access the network and transmit information to the host computer through the networking interface.

[0049] Furthermore, an outdoor temperature and humidity sensor interface can be integrated on the PCB board. The outdoor temperature and humidity sensor interface is connected to the MCU module. The outdoor temperature and humidity sensor interface is used to connect an outdoor temperature and humidity sensor so as to transmit the monitored outdoor temperature and humidity data to the MCU module. The MCU module automatically adjusts the heating and cooling source equipment and the humidification and dehumidification equipment according to the obtained outdoor temperature and humidity data in order to pre-adjust the indoor temperature and humidity.

[0050] Furthermore, an IoT module can also be integrated on the PCB board. The IoT module is connected to the MCU module and is used for network debugging.

[0051] A touch screen 6 can also be designed as needed, and the touch screen 6 can be installed on the outer wall of the housing 1 for personnel to view and operate;

[0052] The connections between the above modules are all relatively mature technologies. For more specific details in actual use, please refer to the existing technologies, which will not be elaborated here. Using this technical solution has the advantages of high compatibility, real-time monitoring, data parsing, user-friendliness, improved efficiency, and reduced costs, and has wide applicability.

They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
