Description

Technical Field

[0001] This invention belongs to the field of dehumidifier technology, specifically relating to a household rotary molecular sieve dehumidifier. Background Technology

[0002] Dehumidifiers, also known as dehumidifiers, dryers, or dehumidifiers, are generally divided into two main categories: residential dehumidifiers and industrial dehumidifiers. They are a part of air-conditioned homes. Typically, a conventional dehumidifier consists of a compressor, heat exchanger, fan, water tank, casing, and controller. Its working principle is as follows: the fan draws humid air into the machine, where it passes through the heat exchanger. At this point, the water molecules in the air condense into water droplets, and the treated dry air is discharged outside the machine. This cycle continues to maintain the indoor humidity at a suitable relative humidity.

[0003] Among dehumidifiers, there is a type called molecular sieve dehumidifier. Compared with traditional refrigeration dehumidifiers, molecular sieve dehumidifiers do not require a lot of electricity or other energy to achieve dehumidification. Therefore, they have low energy consumption and low operating costs. At the same time, no chemical substances are emitted during the molecular sieve dehumidification process, so there is no pollution to the environment. However, existing molecular sieve dehumidifiers need to be shut down and the molecular sieves replaced after working for a period of time, which affects work efficiency and cannot achieve the self-circulation of molecular sieves.

[0004] The prior art, disclosed in CN210292133U, discloses a molecular sieve rotary dehumidifier and dryer, which includes a dehumidifier and dryer shell, a primary dehumidifier filter cloth fixedly connected inside the dehumidifier inlet pipe and located to the left of the dust filter, a molecular sieve dehumidifier rotary wheel rotatably connected inside the dehumidifier and located to the left of the dehumidifier inlet pipe, a primary filter fixedly connected to the left of the regeneration pipe, a regeneration heater fixedly connected inside the regeneration pipe and located to the right of the primary filter, and a high-pressure air pump fixedly connected to the right of the regeneration pipe. The output end of the high-pressure air pump is connected to the main air pipe and the auxiliary high-pressure pipe respectively. Although this technical solution realizes the self-circulation of molecular sieve, its self-circulation efficiency is not high, the structure is not compact, and the regenerated water vapor discharged from the molecular sieve after self-circulation cannot be condensed inside the dehumidifier but is directly discharged, thus failing to achieve the overall dehumidification effect of the room.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This rotary molecular sieve dehumidifier works by using a dehumidifying drive impeller to generate suction, drawing in humid indoor air. Most of the dust is removed through the outlet. The rotary motor drives the impeller via a small gear, causing the molecular sieve to rotate slowly. The dust-removed air passes through the impeller and enters the molecular sieve, where it absorbs moisture. The dehumidifying drive impeller then discharges the dry air into the room through the dry air outlet, achieving indoor dehumidification and improving dehumidification efficiency.

[0016] 2. In this rotary molecular sieve dehumidifier, during the regeneration process of water circulation in the molecular sieve, the regeneration drive impeller draws regeneration air from the regeneration condenser into the regeneration channel. The air is then heated in the regeneration chamber. The high-temperature air passes through the inside of the molecular sieve, carrying out the water molecules adsorbed in the molecular sieve. The regeneration condenser then condenses the regenerated water molecules carried out by the hot air into water, which is then collected in a condensate collection dish. This achieves the purpose of drying the regenerated molecular sieve and simultaneously enables the regenerated water molecules to self-condense inside the dehumidifier, thereby achieving the purpose of indoor dehumidification and drying.

[0017] 3. By setting a heat dissipation mechanism on the outside of the outer shell and the condensate collection dish, the heat dissipation mechanism, with the cooperation of the first condenser tube, the second condenser tube, and the cooling fan, dissipates heat from the inside of the device. Under the action of the cooling fan, outside air enters the device, and at the same time, the water inside the condensate collection dish is circulated between the first condenser tube, the second condenser tube, and the condensate collection dish by the action of the water pump. With the cooperation of the cooling fan, the interaction of air cooling and water cooling dissipates heat from the inside of the device, preventing the components inside the device from generating too much heat and being damaged during operation, thereby increasing the overall heat dissipation performance of the device.

The upper end of the condenser tube 8 is sealed to the first condenser tube 6.

[0035] The working principle and usage process of this invention: During use, the dehumidifying drive impeller motor (301) is energized, and under its action, the dehumidifying drive impeller (302) begins to work, generating suction. Humid air enters through the air inlet (101) and passes through the dust filter element (102) to remove dust from the air. The rotary motor (200) is energized, driving the rotor (203) to rotate through the pinion gear (201). Under the action of the rotor (203), the molecular sieve (202) also rotates with the rotor. 203) rotate together, so that when the humid air passes through, the moisture contained in it can be adsorbed by the molecular sieve (202). The adsorbed dry air is then drawn in by the dehumidification drive impeller (302), and discharged from the outlet (103) through the dry air outlet channel (300). During regeneration, the regeneration impeller motor (400) is energized, and the regeneration drive impeller (401) starts to work to generate suction. The regeneration air is drawn in through the regeneration impeller inlet (402) which is connected to the condenser outlet (503). The air enters through the regeneration channel (404) and then enters the regeneration chamber (405). The regeneration heater (406) fixed inside the regeneration chamber (405) heats the air. The high-temperature regeneration air passes through the inside of the molecular sieve (202), thereby carrying out the water molecules adsorbed in the molecular sieve (202). The regeneration air is then discharged from the regeneration chamber outlet (403) and enters the lower air chamber (504) of the condenser through the condenser inlet (500). The water molecules contained in the regeneration air condense into condensate when they encounter the condenser (501). The condensate is discharged into the condensate collection dish (104) through the condenser drain (505). When dissipating heat, the condensate inside the condensate collection dish (104) is pumped into the first condenser tube (6) by the water pump (11). The condensate circulates between the first condenser tube (6), the second condenser tube (8), and the condensate collection dish (104). With the help of the cooling fan (10), the heat dissipation effect of the internal components of the device is achieved.
