Description

Technical fields:

[0001] This utility model belongs to the field of fresh air equipment technology, specifically referring to a fresh air dehumidifier integrated machine. Background technology:

[0002] A fresh air system is an effective air purification device that can circulate indoor air. On the one hand, it can circulate polluted indoor air through sterilization, disinfection, and filtration, and on the other hand, it can circulate fresh outdoor air through disinfection and filtration, ensuring that the room is always filled with fresh and clean air.

[0003] Currently, the design focus of fresh air systems is primarily on effectively purifying the air, while indoor dehumidification is handled by dehumidifiers. However, when the fresh air system is in external circulation mode, it continuously draws in outdoor air while simultaneously expelling indoor air, resulting in very rapid airflow. At this time, the dehumidifier cannot effectively dehumidify the air. It can only work effectively to reduce indoor humidity when the fresh air system stops operating or switches to internal circulation. Therefore, the combined use of fresh air systems and dehumidifiers results in low and unsatisfactory indoor dehumidification efficiency. Summary of the Invention:

[0004] The purpose of this utility model is to provide a fresh air dehumidifier integrated machine with a simple structure and reasonable design. The dehumidification component is directly designed into the fresh air unit, and the moisture in the air is filtered during the air purification process to achieve effective control of indoor humidity. It has high dehumidification efficiency and good effect.

[0005] This utility model is implemented as follows:

[0006] A fresh air dehumidifier includes a housing with an inner cavity. The housing has an air inlet and an air outlet communicating with the indoor environment at both ends. There are two air inlets, which communicate with the indoor environment and the outdoor environment respectively. Each air inlet is equipped with a valve assembly that can block or open the corresponding air inlet. The inner cavity of the housing is provided with a pre-filter assembly, a dehumidifier assembly, and a post-filter assembly arranged sequentially from the air inlet to the air outlet. A blower installed in the inner cavity of the housing drives the airflow from one of the air inlets through the pre-filter assembly, the dehumidifier assembly, and the post-filter assembly in sequence and blows it out of the air outlet.

[0007] In the aforementioned integrated fresh air dehumidifier, the valve assembly is a louvered valve installed on the inner side of the corresponding air inlet housing.

[0009] In the aforementioned integrated fresh air dehumidifier, the compressor is mounted on a water receiving tank via a raised bracket, and a water-blocking protective plate is provided on the raised bracket located between the compressor and the bottom surface of the water receiving tank.

[0010] In the aforementioned integrated fresh air dehumidifier, the drainage channel is the inner hole of a drain pipe fixed on the housing, with the outer end of the drain pipe extending outward beyond the housing.

[0012] In the aforementioned integrated fresh air dehumidifier, the inner cavity of the housing is provided with two longitudinal slots along the horizontal direction, which correspond to the opening of the housing and are respectively for the insertion and cooperation of the front filter assembly or the rear filter assembly.

[0013] In the above-mentioned integrated fresh air dehumidifier, the pre-filter component is a pre-filter, and the post-filter component is composed of a medium-efficiency filter and a high-efficiency filter stacked in front and behind.

[0014] Alternatively, the pre-filter assembly may consist of a primary filter and a medium-efficiency filter stacked one after the other, and the post-filter assembly may be a high-efficiency filter.

[0023] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —3:

[0024] A fresh air dehumidifier includes a housing 1 with an inner cavity. Two air inlets 2 and two air outlets 3 communicating with the indoor environment are respectively provided at both ends of the housing 1. Each air inlet 2 is equipped with a valve assembly 4 capable of blocking or opening the corresponding air inlet 2. A pre-filter assembly 5, a dehumidifier assembly, and a post-filter assembly 6 are sequentially arranged on the inner cavity of the housing 1 from the air inlets 2 to the air outlets 3. An airflow driven by a blower 7 located on the inner cavity of the housing 1 flows through one of the air inlets 2, sequentially through the pre-filter assembly 5, the dehumidifier assembly, and the post-filter assembly 6, and then exits through the air outlet 3. That is, by controlling the opening and closing of the two air inlets 2 with the valve assembly 4, it enables internal circulation filtration and dehumidification of indoor air, as well as external circulation filtration and dehumidification of outdoor air between the indoor and outdoor environments. Furthermore, the pre-filter assembly 5 can effectively filter larger particles, while the post-filter assembly 6 can filter bacteria, allergens, and fine particulate matter.

[0025] This utility model has a simple structure, reasonable design, and low cost. By designing the dehumidification component inside the fresh air unit, it filters out moisture in the air during the air purification process, so that the fresh air blown into the room does not have excessive moisture, thus achieving effective control of indoor humidity. It has high dehumidification efficiency and good dehumidification effect.

[0026] In this embodiment, to achieve the switching between internal and external air circulation, the valve assembly 4 is a louvered valve installed on the inner housing 1 of the corresponding air inlet 2. The actuator of the louvered valve is connected to the drive source, and the drive source is electrically connected to the control assembly. The control assembly controls the drive source to drive the corresponding louvered valve, thereby controlling the blocking or opening of the corresponding air inlet 2. Furthermore, the drive source can be a common drive motor or a drive cylinder.

[0027] Furthermore, the dehumidification component can be a commercially available dehumidifier. In this embodiment, the dehumidification component includes a compressor 8, an evaporator 9, and a condenser 10 mounted on the housing 1. The refrigerant outlet of the compressor 8 is connected to the refrigerant inlet of the condenser 10. The refrigerant outlet of the condenser 10 is connected to one end of an expansion valve, and the other end of the expansion valve is connected to the refrigerant inlet of the evaporator 9. The refrigerant outlet of the evaporator 9 is connected to the refrigerant inlet of the compressor 8. The evaporator 9 is located near the air inlet 2, and a water collection tank 11 is provided on the inner cavity of the housing 1 below the evaporator 9. A drainage channel communicating with the outside is provided on the water collection tank 11. The condenser 10 is located between the evaporator 9 and the post-filter assembly 6. That is, by utilizing the heat absorption effect of the evaporator 9, the moisture in the air can be condensed and dripped into the water collection tank 11, and finally discharged outside the housing 1 of the integrated unit through the drainage channel. The heat release effect of the condenser 10 can dry the air after the moisture has been condensed, resulting in a good dehumidification effect.

[0028] Meanwhile, the compressor 8 is specifically positioned inside the housing 1: the compressor 8 is mounted on the water receiving tank 11 via a lifting bracket 12, and to prevent condensate from affecting the compressor 8, a water-blocking protective plate 13 is provided on the lifting bracket 12 located between the compressor 8 and the bottom surface of the water receiving tank 11.

[0029] Furthermore, in order to effectively drain the condensate in the water receiving tank 11, the drainage channel is the inner hole of the drain pipe 14 fixed on the housing 1, and the outer end of the drain pipe 14 extends outward beyond the housing 1.

[0030] Considering that the pre-filter assembly 5 and the post-filter assembly 6 need to be replaced periodically, to facilitate the replacement operation, one side wall of the housing 1 is an open structure covered with a side-opening door 15. One side of the side-opening door 15 is hinged to the housing 1, and the other side of the side-opening door 15 is a free end, which is fixed to the housing 1 by a locking assembly 16. The pre-filter assembly 5 and the post-filter assembly 6 are separate from the housing 1, and the opening of the housing 1 is the access channel for the pre-filter assembly 5 and the post-filter assembly 6 to enter and exit the inner cavity of the housing 1. The locking assembly 16 can adopt a common lock tongue and lock groove cooperation structure, a card block and card box cooperation structure, or a pin and hole cooperation structure, etc.

[0031] Furthermore, in order to enable the pre-filter assembly 5 and the post-filter assembly 6 to be quickly assembled and disassembled from the housing 1, the inner cavity of the housing 1 is provided with two longitudinal slots along the horizontal direction, which correspond to the opening position of the housing 1 and are respectively for the pre-filter assembly 5 or the post-filter assembly 6 to be inserted and engaged.

[0032] Furthermore, in this embodiment, the pre-filter component 5 is a primary filter, and the post-filter component 6 is composed of a medium-efficiency filter and a high-efficiency filter stacked one after the other.

[0033] Of course, depending on the actual design requirements, the pre-filter assembly 5 and the post-filter assembly 6 can also be: the pre-filter assembly 5 is composed of a primary filter and a medium-efficiency filter stacked one after the other, and the post-filter assembly 6 is a high-efficiency filter; or the pre-filter assembly 5 is a primary filter and the post-filter assembly 6 is a high-efficiency filter.

[0034] In addition, in order to enable the blower 7 to effectively drive the air to flow inside the housing 1, the blower 7 is a centrifugal blower, and it is installed on the inner cavity of the housing 1 between the rear filter assembly 6 and the air outlet 3, with the inner end of the air outlet 3 connected to the air outlet end of the blower 7.

[0035] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
