[0001] The invention relates to the technical field of dehumidifiers, and in particular to a fresh air system duct dehumidifier for a clean room. Background Art

[0002] In a clean room environment, air quality is crucial to the accuracy and safety of production and experiments. Therefore, fresh air system duct dehumidifiers are widely used in such environments. Their main function is to ensure that the air in the clean room is maintained at an appropriate humidity and cleanliness through dehumidification and filtration.

[0003] However, as the use time increases, the filter inside the fresh air system duct dehumidifier is prone to accumulate dust and bacteria.

[0020] 3. When the control member descends to the lowest position, the rack segment of the control member is temporarily separated from the gear. At this time, under the elastic force of the third elastic member, the control member can be driven to move upward, and the rack segment and the gear are re-engaged. When the gear rotates in the opposite direction, the control member can be driven to rise. When the control member rises to the highest position, under the elastic force of the second elastic member, the rack segment of the control member can be brought into contact with the gear. When the gear rotates, the control member can be driven to descend again, which further improves the convenience and practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] Example 1, reference Figure 1-Figure 10 , which is the first embodiment of the present invention, provides a fresh air system duct dehumidifier for a clean room, including a base plate 1, a first shell 2 fixedly installed on the top surface of the base plate 1, a clamping plate 3 fixedly installed on the top surface of the first shell 2, an outdoor air inlet 8 arranged on the outer wall of the first shell 2, a fan 9 arranged inside the first shell 2, an outdoor air outlet 10 arranged on the outer wall of the first shell 2, an indoor fresh air outlet 11 arranged on the outer wall of the first shell 2, an indoor air outlet 12 arranged on the outer wall of the first shell 2, a filter mounting seat 14 detachably mounted on the inside of the base plate 1, a high-efficiency filter 16 clamped inside the filter mounting seat 14, and a dehumidification mechanism 5 arranged inside the first shell 2, and the top surface of the filter mounting seat 14 is tightly fitted with the bottom surface of the clamping plate 3.

[0035] Specifically, the outdoor air inlet 8, the outdoor air outlet 10, the indoor fresh air outlet 11 and the indoor air outlet 12 are all connected to ventilation ducts on the side away from the first shell 2, and the high-efficiency filter 16 corresponds to the position of the outdoor air inlet 8. In addition, the dehumidification mechanism 5 includes a condenser (evaporator), a compressor, a full heat exchange core, an electric air valve and a drain outlet arranged inside the first shell 2.

[0036] The working principle of the fresh air system duct dehumidifier is as follows: the fresh air system inhales outside air into the first shell 2 through the outdoor air inlet 8 and the connected ventilation duct. The air first flows through the high-efficiency filter 16 arranged in the system to remove dust, particulate matter and some microorganisms in the indoor air to ensure the cleanliness of the air transported to the clean room. After passing through the high-efficiency filter 16, the air enters the core part of the dehumidification mechanism 5, where the air is cooled by the condenser (evaporator). The condenser (evaporator) reduces the air temperature and condenses the water vapor in the air into liquid water to achieve the purpose of dehumidification. The condensed water is collected and discharged from the system through the drain port. In order to avoid the air temperature being too low, the dehumidified and cooled air can be heat recovered through the full heat exchange core. The full heat exchange core exchanges heat with the exhausted air in the building to increase the temperature of the fresh air and maintain suitable temperature conditions in the room. The electric air valve is used to adjust the airflow and control the air volume according to demand to further ensure that the air delivered to the clean room meets the temperature and humidity requirements. The processed air is pushed by the fan 9 and transported to the interior of the clean room through the ventilation duct connected to the indoor fresh air outlet 11. In order to maintain the indoor air flow and positive pressure state, the indoor exhaust air is discharged through the indoor exhaust outlet 12 and released to the external environment through the indoor exhaust outlet 12.

[0037] Reference Figure 2A second shell 6 is fixedly installed on the top surface of the clamping plate 3, a top plate 4 is fixedly installed on the top surface of the second shell 6, a lifting ear 7 is fixedly installed on the outer wall of the second shell 6, a mounting plate 13 is fixedly installed on the top surface of the bottom plate 1, an L-shaped plate 15 is fixedly installed on the top surface of the bottom plate 1, and the inner wall of the L-shaped plate 15 is slidably fitted with the outer wall of the filter mounting seat 14, a sealing plate 32 is fixedly installed on the bottom surface of the filter mounting seat 14, a card slot 31 is opened on the bottom surface of the bottom plate 1, and the outer wall of the sealing plate 32 is slidably fitted with the inner wall of the card slot 31.

[0038] Specifically, by cooperating between the second shell 6, the top plate 4 and the lifting ear 7, an installation space can be provided for the fresh air system duct dehumidifier. When the filter mounting seat 14 and the high-efficiency filter 16 are installed, a sliding seal is formed between the outer wall of the filter mounting seat 14 and the clamping plate 3 and the L-shaped plate 15, and air can pass through the high-efficiency filter 16 smoothly.

[0039] Reference Figure 3-Figure 4 A rotating rod 17 is rotatably installed on the top of the splint 3, and a connecting piece 18 is wrapped around the rod wall of the rotating rod 17. A sealing ring 19 is fixedly connected to the top surface of the splint 3 for the connecting piece 18 to pass through. A through hole is opened on the top surface of the splint 3 for the connecting piece 18 to pass through, and one end of the connecting piece 18 is fixedly connected to the rod wall of the rotating rod 17, and the other end of the connecting piece 18 is connected to the filter mounting seat 14.

[0040] Specifically, the sealing ring 19 can guide the connecting member 18, which is conducive to the rotation of the rotating rod 17 to reel in the connecting member 18. The connecting member 18 can be a connecting rope or connecting chain commonly used in the prior art. The present device uses the connecting member 18 to lift and lower the high-efficiency filter 16. Compared with the use of traditional electric screws or electric telescopic cylinders, the device does not occupy the normal use space of the indoor floor, making the present device more practical.

[0041] Reference Figure 5 The outer wall of the filter mounting seat 14 is fixedly connected with a fixed cover 28, and a J-shaped plate 29 is inserted inside the fixed cover 28, and the outer wall of the J-shaped plate 29 is slidably fitted with the inner wall of the fixed cover 28, and the other end of the connecting piece 18 is fixedly connected with the top surface of the J-shaped plate 29.

[0042] Specifically, through the cooperation between the fixed cover 28 and the J-shaped plate 29, the installation and disassembly between the connecting piece 18 and the filter mounting seat 14 can be realized, further improving the convenience of people in cleaning the high-efficiency filter 16.

[0043] Reference Figure 3-Figure 4The top surface of the splint 3 is fixedly connected to the first fixed seat 20, and the rotating rod 17 is rotatably installed on the outer wall of the first fixed seat 20, the top surface of the splint 3 is fixedly connected to the second fixed seat 30, the outer wall of the second fixed seat 30 is rotatably installed with a worm 22, and the end of the worm 22 away from the second fixed seat 30 is rotatably connected to the inner wall of the second shell 6, the rod wall of the rotating rod 17 is sleeved with a worm wheel 23 that is mutually adapted to the rod wall of the worm 22, and the side of the second fixed seat 30 away from the worm 22 is fixedly installed with a motor 21, and the output shaft of the motor 21 is fixedly connected to the axial end of the worm 22.

[0044] Specifically, the motor 21 can be a common driving motor in the prior art, and its specific model can be determined according to actual usage requirements. No further details will be given here. By controlling the output shaft of the motor 21 to rotate, the worm 22 can be driven to rotate, and the rotation of the worm 22 drives the worm wheel 23 to rotate. Through the unidirectional transmission between the worm 22 and the worm wheel 23, the stability of the device during use can be further improved, and the filter mounting seat 14 can be effectively prevented from accidentally falling. The rotation of the worm wheel 23 drives the rotating rod 17 to rotate, and then the connecting member 18 can be released or reeled up.

[0045] Reference Figure 7 A guide plate 33 for guiding the sealing plate 32 is fixedly connected to the bottom surface of the bottom plate 1 .

[0046] Specifically, the guide plate 33 is provided to effectively correct the rising trajectory of the filter mounting seat 14 , so that the filter mounting seat 14 can smoothly pass through the slot 31 and enter the interior of the first housing 2 .

[0047] Example 2, reference Figure 1-Figure 10 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a control member 25 is slidably installed inside the second shell 6, a first through groove 26 for the control member 25 to pass through is formed on the top surface of the clamping plate 3, a second through groove 27 for the control member 25 to pass through is formed on the top surface of the clamping plate 3, a limiting plate 44 is fixedly connected to the top surface of the clamping plate 3, and the outer wall of the limiting plate 44 is slidably fitted with the outer wall of the control member 25.

[0048] Specifically, through the cooperation between the first through slot 26 , the second through slot 27 and the limiting plate 44 , it can be ensured that the control member 25 only performs lifting movement in the vertical direction.

[0049] Reference Figure 7-Figure 9The bottom of the bottom plate 1 is elastically mounted with a baffle 34 for blocking the sealing plate 32, and the bottom surface of the bottom plate 1 is provided with a slide groove 36 for the baffle 34 to slide. The bottom surface of the baffle 34 is inclined and fits the top surface of the sealing plate 32. The inner wall of the first shell 2 is fixedly connected with a first elastic member 35, and one end of the first elastic member 35 away from the inner wall of the first shell 2 is fixedly connected with the outer wall of the baffle 34.

[0050] Specifically, by controlling the movement of the baffle 34, the installation of the filter mounting seat 14 can be further reinforced and supported, preventing the filter mounting seat 14 and the high-efficiency filter 16 from accidentally falling off, thereby improving the safety and reliability of the equipment.

[0051] When the rotating rod 17 rotates to drive the filter mounting seat 14 to rise, the outer wall of the filter mounting seat 14 squeezes the bottom surface of the baffle 34, which can drive the baffle 34 to slide in the direction away from the filter mounting seat 14. At this time, the baffle 34 squeezes the first elastic member 35. When the filter mounting seat 14 is completely received into the first shell 2, the sealing plate 32 is engaged in the slot 31. The elastic force of the first elastic member 35 can drive the baffle 34 to reset. The baffle 34 can reinforce and support the sealing plate 32, effectively reducing the fatigue of the connecting member 18 and improving the durability of the device.

[0052] Reference Figure 8-Figure 9 The control member 25 includes a driving section 39, a horizontal section 40 and a pushing section 41, and the bottom end of the pushing section 41 corresponds to the top surface position of the filter mounting seat 14, the top surface of the baffle 34 is inclined, the bottom end of the driving section 39 and the top surface of the baffle 34 are adapted to each other, and the bottom surface of the bottom plate 1 is provided with a third through groove 37 for the driving section 39 to pass through.

[0053] Specifically, through the cooperation between the set push section 41 and the second through groove 27, when the high-efficiency filter 16 needs to be cleaned, the filter mounting seat 14 can be assisted in being pushed down, thereby preventing the high-efficiency filter 16 and the filter mounting seat 14 from getting stuck or jammed during descent due to accumulation of dust on the surface. This design enables the filter mounting seat 14 to smoothly detach from the interior of the first shell 2, ensuring the smooth descent of the high-efficiency filter 16. The third through groove 37 provides a descending space for the driving section 39 of the control member 25.

[0054] By controlling the control member 25 to descend, the driving section 39 can push the baffle 34 to move away from the sealing plate 32, so that the baffle 34 no longer blocks the sealing plate 32, and then the two pushing sections 41 can assist in pushing the filter screen mounting seat 14 down, so that the filter screen mounting seat 14 can be smoothly separated from the first housing 2. The rest of the structure is the same as that of Example 1.

[0055] Example 3, reference Figure 1-Figure 10, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the control member 25 also includes a rack segment 38, and two rotating rods 17 are provided. The rod wall of one of the rotating rods 17 is sleeved with a gear 24, and the outer wall of the rack segment 38 is meshed with the outer wall of the gear 24.

[0056] Specifically, when the output shaft of the motor 21 rotates, driving the rotating rod 17 to rotate, the gear 24 rotates to drive the rack segment 38 of the control member 25 to descend, so that the two pushing segments 41 can assist in pushing the filter mounting seat 14 down, so that the filter mounting seat 14 can smoothly detach from the first shell 2. When the output shaft of the motor 21 rotates in the reverse direction, the gear 24 rotates in the reverse direction to drive the rack segment 38 of the control member 25 to rise, driving the control member 25 to reset.

[0057] Reference Figure 8 The top surface of the horizontal section 40 is fixedly connected to a second elastic member 42 , and the bottom surface of the horizontal section 40 is fixedly connected to a third elastic member 43 .

[0058] When the control member 25 is lowered to the lowest position, the rack segment 38 of the control member 25 is temporarily separated from the gear 24. At this time, under the elastic force of the third elastic member 43, the control member 25 can be driven to move upward, and the rack segment 38 and the gear 24 are re-engaged. When the gear 24 rotates in the opposite direction, the control member 25 can be driven to rise. When the control member 25 rises to the highest position, under the elastic force of the second elastic member 42, the rack segment 38 of the control member 25 can be brought into contact with the gear 24. When the gear 24 rotates, the control member 25 can be driven to fall again, further improving the convenience and practicality of the device. The rest of the structure is the same as that of Example 2.

[0059] Based on Example 1 to Example 3, the working principle of the present invention is as follows:

[0060] The fresh air system draws in outside air into the first shell 2 through the outdoor air inlet 8 and the connected ventilation duct. The air first flows through the high-efficiency filter 16 arranged in the system to remove dust, particulate matter and some microorganisms in the indoor air to ensure the cleanliness of the air delivered to the clean room. After passing through the high-efficiency filter 16, the air enters the core part of the dehumidification mechanism 5, where the air is cooled by the condenser (evaporator). The condenser (evaporator) reduces the air temperature and condenses the water vapor in the air into liquid water to achieve the purpose of dehumidification. The condensed water is collected and discharged from the system through the drain port. In order to avoid the air temperature If the temperature is too low, the dehumidified and cooled air can be recovered through the full heat exchange core. The full heat exchange core exchanges heat with the exhausted air in the building to increase the temperature of the fresh air and maintain suitable temperature conditions in the room. The electric air valve is used to adjust the airflow and control the air volume according to demand to further ensure that the air delivered to the clean room meets the temperature and humidity requirements. The treated air is pushed by the fan 9 and transported to the interior of the clean room through the ventilation duct connected to the indoor fresh air outlet 11. In order to maintain the indoor air flow and positive pressure state, the indoor exhaust air is discharged through the indoor exhaust outlet 12 and released to the external environment through the indoor exhaust outlet 12.

[0061] When people need to clean the high-efficiency filter 16, by controlling the output shaft of the motor 21 to rotate, the worm 22 can be driven to rotate, the worm 22 rotates to drive the worm wheel 23 to rotate, the worm wheel 23 rotates to drive the rotating rod 17 to rotate, the gear 24 rotates to drive the rack section 38 of the control member 25 to descend, and the driving section 39 can push the baffle 34 to move away from the sealing plate 32, so that the baffle 34 no longer blocks the sealing plate 32, and then the two pushing sections 41 can assist in pushing the filter mounting seat 14 to descend, so that the filter mounting seat 14 can smoothly detach from the first shell 2, thereby preventing the high-efficiency filter 16 and the filter mounting seat 14 from getting stuck or jammed when descending due to dust accumulation on the surface.

[0062] When the filter mounting seat 14 is lowered to the indoor floor, people can separate the filter mounting seat 14 from the connecting piece 18 and clean the filter mounting seat 14, which further improves the convenience of using the device.

[0063] When the filter is cleaned, the filter mounting seat 14 is reconnected to the connecting member 18, and then the output shaft of the motor 21 is controlled to rotate in the opposite direction to drive the filter mounting seat 14 to rise. At the same time, when the gear 24 rotates in the opposite direction, it can drive the control member 25 to rise and reset. The guide plate 33 is provided to effectively correct the rising trajectory of the filter mounting seat 14.

[0064] When the outer wall of the filter mounting seat 14 squeezes the bottom surface of the baffle 34, the baffle 34 can be driven to slide in the direction away from the filter mounting seat 14, and the filter mounting seat 14 can smoothly pass through the card slot 31 into the interior of the first shell 2. At this time, the baffle 34 squeezes the first elastic member 35. When the filter mounting seat 14 is completely received in the interior of the first shell 2, the sealing plate 32 is engaged in the card slot 31. The elastic force of the first elastic member 35 can drive the baffle 34 to reset. The baffle 34 can reinforce and support the sealing plate 32, effectively reducing the fatigue of the connecting member 18 and improving the durability of the device.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
