Description

Technical Field

[0001] The present application relates to the technical field of dehumidifier structural design, and in particular to a novel air inlet structure of a dehumidifier. Background Art

[0002] A humid environment is detrimental to human activity and the storage and use of equipment. Dehumidifiers, however, dry the air, allowing people and equipment to operate in an environment with optimal humidity. Existing dehumidifiers typically consist of an evaporator and a condenser, which together form a refrigeration cycle. During operation, the evaporator achieves an evaporation temperature below the ambient air's dew point. As air passes through the evaporator, once the air temperature drops below the dew point, moisture condenses from the air. This low-temperature, low-humidity air, condensed by the evaporator, then passes through the condenser, where it heats the air with the high-temperature, high-pressure refrigerant gas inside before being transported back to the indoor environment, minimizing the impact of the low-temperature air on the environment.

[0003] For example, the Chinese invention patent with application number CN202211026849.7 is a dehumidifier with an auxiliary condensation structure, which relates to the technical field of dehumidifiers and includes a shell, on which an air inlet and an air outlet are opened; an evaporator, which is arranged at the air inlet; a condensation component, which is arranged on the side of the evaporator away from the air inlet and is in contact with the evaporator; a radiator, which is arranged on the side of the condensation component away from the evaporator and forms a gap between the condensation component and the condensation component; and a compressor, which is connected to the evaporator.

[0004] Among them, although the above solution uses a condensing component to make the dehumidifier produce more water on an existing basis, thereby improving the dehumidifier's energy efficiency, this solution also has certain defects in practice. The main one is that after the air enters the condenser and is discharged from the lower end of the condenser, there is a shielding structure inside the dehumidifier, which creates wind resistance at this location, resulting in unsatisfactory airflow and affecting the dehumidification effect. In addition, after the air enters the condenser, although some of the air contacts the inner wall of the condenser to complete the condensation process, a large amount of air (the air in the middle of the condenser) will not contact the inner wall of the condenser, resulting in poor condensation effect. Utility Model Content

DETAILED DESCRIPTION

[0036] The present application is further described in detail below with reference to the accompanying drawings.

[0037] A novel air inlet structure for a dehumidifier, comprising:

[0038] The fixing frame 1 is arranged inside the dehumidifier, and has an air duct 103 therein, the purpose of which is to improve the air circulation capacity and the air flow effect, and improve the dehumidification effect; there is a concave water collecting tank 104 at the bottom, the purpose of setting the water collecting tank 104 is to allow the condensed water to be collected on the water collecting tank 104, so as to facilitate centralized discharge.

[0039] It also includes a plurality of condensing tubes 2, which are mounted on the fixing frame 1, and whose internal cavities are connected to the air duct 103 inside the fixing frame 1, for contact with hot air to achieve condensation effect. Among them, the condensing tubes 2 are arranged at equal intervals on the fixing frame 1, and the condensing tubes 2 are round tubes, which have better ventilation effect;

[0040] The air can enter the air duct 103 of the fixing frame 1 from the inner cavity of the condensing tube 2 and be discharged along the outlet of the air duct 103 . Meanwhile, the condensed water can be collected in the water collecting tank 104 .

[0041] The dehumidifier includes a casing 9, one side surface of which is provided with an air inlet grille 903, and an air inlet 901 is also provided on the casing 9; in addition, a fan 7 is installed inside the casing 9, and an air outlet grille 904 is provided above the casing 9; wherein, the air inlet grille 903 is used to allow air to enter the interior of the dehumidifier and then pass through the evaporator 3 and the radiator 4 in sequence, an isolation frame 902 connected to the air inlet 901 is installed in the casing 9, and the upper end of the condensation tube 2 is installed on the isolation frame 902, and the air entering the dehumidifier from the air inlet 901 can enter the condensation tube 2 to achieve a condensation effect.

[0042] Specifically, the fixing frame 1 is provided with a plurality of mounting holes 102 arranged at equal intervals, and the mounting holes 102 are connected to the internal air duct 103 of the fixing frame 1, and the condenser 2 is fixed at the position of the mounting hole 102, wherein the mounting hole 102 is the air inlet of the air duct 103 on the fixing frame 1, and is used to connect the condenser 2, so that the air entering the condenser 2 can be further quickly discharged outward along the air duct 103, thereby improving the air flow efficiency.

[0043] There is an air inlet gap a between the upper end of the condenser tube 2 and the top wall of the isolation frame 902; there is an air outlet gap b between the lower end of the condenser tube 2 and the bottom wall of the fixing frame 1, wherein the dimension a>b, such as Figure 9 As shown, since the gap a at the upper end of the air inlet of the condenser 2 is larger than the gap b at the lower end of the air outlet, the air can stay in the condenser 2 for a longer time, fully realizing heat exchange, thereby improving the condensation effect.

[0044] Specifically, the root plane of the water collection tank 104 is an inclined surface, and a downward extending drain pipe 105 is installed at the lowest point of the inclined surface. The drain pipe 105 is connected to the internal cavity of the fixing frame 1 and is mainly used to discharge the condensed and liquid water from the drain pipe 105.

[0045] Specifically, it also includes: a center rod 5, which is coaxially arranged in the internal position of the condenser 2, and a gap is formed between the outer wall of the center rod 5 and the inner wall of the condenser 2. The gap is configured to allow the air entering the condenser 2 to flow along the inner wall of the condenser 2, thereby improving the condensation effect.

[0046] More specifically, a plurality of support blocks 6 are fixed on the outer wall of the center rod 5, and the outer ends of the support blocks 6 are in contact with the inner walls of the condenser 2, so as to place the center rod 5 in the center position of the condenser 2; more specifically, among the plurality of support blocks 6, every four support blocks 6 form a group and are arranged at equal intervals along the length direction of the center rod 5, and the four support blocks 6 in each group are evenly distributed around the center line of the center rod 5. The structure of the center rod 5 and the support blocks 6 are mainly used to achieve the effect of turbulence, forcing the liquid entering the condenser 2 to fit the inner wall of the condenser 2 and flow out, thereby fully realizing the heat exchange process and improving the condensation effect.

[0047] Specifically, it also includes:

[0048] The evaporator 3 is fixed on the fixing frame 1 and is close to the air inlet of the dehumidifier. The evaporator 3 is in contact with the condenser tube 2.

[0049] The radiator 4 is fixed on the fixing frame 1 and is close to one side of the fan 7 , with a gap between the radiator 4 and the condenser tube 2 .

[0050] Specifically, the evaporator 3 and the radiator 4 are both fin-type structures, and U-shaped tubes 8 are installed inside both. Positioning grooves 101 corresponding to the cross-sectional shape of the U-shaped tube 8 and used to position the evaporator 3 and the radiator 4 are provided on both sides of the fixing frame 1.

[0051] The finned structure of the evaporator 3 and radiator 4, as well as the internally mounted U-shaped tube 8, are conventional designs in the prior art and will not be described in detail here. Positioning slots 101 are provided on either side of the mounting bracket 1. These slots facilitate quick installation of the evaporator 3 and radiator 4 onto the mounting bracket 1 and serve as position limits. This allows the evaporator 3, radiator 4, mounting bracket 1, and condenser tube 2 to function as a single, integrated assembly that can be installed within the dehumidifier. This simplifies the installation process and avoids assembly errors and potential issues.

[0052] Specifically, the outlet of the internal air duct 103 of the fixing frame 1 is directed toward the fan 7 inside the dehumidifier. Figure 7 As shown, air enters the condenser 2 from the outside of the dehumidifier. On the one hand, it condenses into water in the condenser 2, falls into the water collection tank 104 below, and is finally discharged from the drain pipe 105. On the other hand, the air that has undergone heat exchange flows to the left in the direction of the arrow from the outlet of the air duct 103, and is finally discharged from the outside of the dehumidifier under the action of the fan 7, so as to make the wind effect more normal and the dehumidification effect better. In addition, the cross-sectional size of the air inlet of the dehumidifier is larger than the cross-sectional size of the air outlet of the air duct 103, so that in the process of air entering the condenser 2, the air duct 103, and being discharged from the air duct 103 from the dehumidifier inlet, resistance is formed at the air outlet of the air duct 103, which slows down the air flow rate in the pipeline, thereby increasing the time that the air stays in the condenser 2, and further improving the condensation effect.

[0053] By changing the dehumidifier's air intake structure and method, the dehumidifier's internal airflow efficiency is significantly improved, thereby enhancing dehumidification performance. Compared to the 15.5L / day dehumidification capacity described in the background art, this solution increases dehumidification capacity by at least 1L / day. This method also offers low cost and high dehumidification performance.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
