Description

Technical Field

[0001] This utility model relates to the field of dehumidification equipment technology, specifically to a dehumidifier with an adjustable airflow path. Background Technology

[0002] The outlet air temperature of the rear rotor of a dual-rotor dehumidifier is generally 15~18℃. After passing through the rear surface cooler, the outlet air is cooled to 12~15℃ before being delivered to the target room. The comfortable temperature of the target room is 25℃±3℃, which is usually controlled by the circulating air handling unit and the dehumidifier. This means the dehumidifier's air supply undertakes part of the cooling load. Considering the outlet air temperature of 15~18℃ from the rear rotor of the dehumidifier, this temperature already provides sufficient cooling capacity; the rear surface cooler only undertakes a small portion of the cooling capacity.

[0003] Outdoor temperatures vary with the seasons. In spring, autumn, and winter, outdoor temperatures are low, reducing the cooling load on the target room and eliminating the need for large amounts of cooling. Existing dehumidifiers have fixed surface coolers and a single, unadjustable airflow path; the airflow must pass through the surface cooler regardless of its functionality. When the cooling load on the target room decreases, the cooling function of the subsequent surface cooler weakens or even ceases to function, causing pressure losses ranging from 100 to 300 Pa and increasing the fan's energy consumption.

[0029] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] Please refer to Figure 1 as well as Figure 2 A dehumidifier with an adjustable airflow path includes a fresh air outlet, a movable component and a third surface cooler are provided at the fresh air outlet, the movable component is connected to the third surface cooler to control the third surface cooler to block or move away from the fresh air outlet.

[0031] As described above, the beneficial effects of this utility model are as follows: Installing a third surface cooler at the fresh air outlet allows the third surface cooler to block or move away from the fresh air outlet, altering the airflow path. When the ambient temperature is high (summer), moving the third surface cooler to block the fresh air outlet ensures the airflow is cooled by the third surface cooler before being delivered to the target room, preventing overheating of the target room due to the dehumidifier. When the ambient temperature is low (spring, autumn, winter) and less cooling is needed, moving the third surface cooler away from the fresh air outlet allows the airflow to bypass the third surface cooler, saving pressure loss of 100-300 Pa, reducing fan energy consumption, and achieving energy-saving effects.

[0032] Please refer to Figure 7 Furthermore, the moving component includes a ball screw and a ball slider, the ball screw and the ball slider being connected by a ball thread, and the ball slider being connected to a third surface cooler.

[0033] As can be seen from the above description, the third surface cooler moves axially on the ball screw via a ball slider.

[0034] Furthermore, the axis of the ball screw is perpendicular to the direction of the fresh air outlet.

[0035] Please refer to Figures 3-6 Furthermore, the moving component also includes an electric motor, which is connected in sequence to a connecting rod and a first gear, and one end of a ball screw is connected to a second gear, with the first gear and the second gear meshing.

[0036] As can be seen from the above description, the electric motor sequentially drives the connecting rod, the first gear, the second gear, and the ball screw to provide power for the movement of the third surface cooler.

[0037] Furthermore, one end of the ball screw is connected to the second gear through the first bearing connecting rod, and the first bearing and the first bearing fixing sleeve are sequentially sleeved on the outside of the first bearing connecting rod.

[0038] Furthermore, it also includes a housing, with a fresh air outlet located on the housing. The other end of the ball screw is connected to the housing via a second bearing connecting rod, and a second bearing and a second bearing fixing sleeve are sequentially fitted onto the outside of the second bearing connecting rod.

[0039] As can be seen from the above description, the ball screw is connected by a bearing connecting rod, a bearing, and a bearing retaining sleeve, which improves the stability of the ball screw rotation.

[0040] Furthermore, a first limit switch is provided at the end of the ball screw away from the fresh air outlet.

[0041] Furthermore, a second limiter is provided at the other end of the ball screw.

[0042] Furthermore, a second limiter is provided on the ball screw or the housing.

[0043] As can be seen from the above description, the movement position of the third surface cooler is precisely controlled by the first and second limiters to avoid excessive sliding.

[0044] Furthermore, the moving component also includes a guide rail, the axis of which is parallel to the axis of the ball screw, and a third surface cooler connected to a bearing, which is inserted into the guide rail and slidably connected to it.

[0045] As can be seen from the above description, when the ball screw drives the third surface cooler to move, the bearing on the third surface cooler moves in the guide rail, which improves the stability of the third surface cooler when it moves.

[0046] Furthermore, the third surface cooler is connected to the inlet hose and the outlet hose.

[0047] As can be seen from the above description, the use of flexible hoses to connect the inlet and outlet water outlets ensures that the chilled water circulation can continue even when the third surface cooler is moved.

[0048] Furthermore, a sealing ring is installed on the outer casing of the third surface cooler.

[0049] Furthermore, the shape of the sealing ring is adapted to the fresh air inlet.

[0050] As can be seen from the above description, the sealing ring is installed to prevent the air from leaking out directly from the fresh air outlet without passing through the third surface cooler.

[0051] Furthermore, the housing is equipped with a return air inlet, and a temperature sensor is installed at the return air inlet.

[0052] As described above, the return air temperature is measured by a temperature sensor. When the return air temperature is higher than the target room set temperature, the third surface cooler is controlled to block the fresh air outlet for cooling.

[0056] The moving component 2 includes a motor 21, a ball screw 22, a ball slider 23, and a guide rail 24. The ball screw 22 and the ball slider 23 are threaded together by balls 231. The ball slider 23 is connected to the third surface cooler 102. The axial direction of the ball screw 22 is perpendicular to the air outlet direction of the fresh air.

[0057] The principle of this utility model is as follows:

[0058] When the temperature sensor 106 detects that the return air temperature is higher than the target room set temperature, the motor 21 sequentially drives the connecting rod 211, the first gear 212, the second gear 221, the ball screw 22, and the ball slider 23, driving the third surface cooler 102 to move to the second limiter 27, which blocks the fresh air outlet 12, so that the fresh air passes through the fresh air inlet 11, the fresh air valve 3, the first surface cooler 4, the first filter 5, the first rotor 6, the first air supply fan, the second surface cooler 8, the second filter 9, the second rotor 10, the second air supply fan 101, the third surface cooler 102, the fresh air outlet 12, and the air supply valve 121, thereby achieving cooling of the outlet air.

[0059] When the temperature sensor 106 detects that the return air temperature is less than or equal to the target room set temperature, the motor 21 sequentially drives the connecting rod 211, the first gear 212, the second gear 221, the ball screw 22, and the ball slider 23, driving the third surface cooler 102 to move to the first limit switch 26, moving it away from the fresh air outlet 12.
