Description

Technical Field

[0001] This invention belongs to the field of dehumidification equipment design technology, specifically relating to a dehumidifier with independent cold air duct and hot air duct. Background Technology

[0002] Most mainstream dehumidifiers on the market consist of a compressor, heat exchanger, fan blades, water tank, casing, and controller. Their working principle is as follows: the fan blades draw humid air into the machine, and through the low-temperature heat exchanger, the moisture in the air condenses into small water droplets. The treated dry air is then discharged outside the machine, and this cycle is repeated to maintain the indoor humidity at a suitable relative humidity.

[0003] Currently, dehumidifiers primarily regulate room humidity, making their function relatively simple. Furthermore, they are temperature-rising dehumidifiers, causing the room temperature to gradually increase, thus reducing comfort. To overcome these shortcomings, related technologies have provided dehumidifiers capable of blowing both cool and hot air. However, due to considerations of structural compactness, the cool and hot air ducts in these technologies are separated by a guide vane within a single duct housing. This results in heat transfer between the cool air in the cool duct and the hot air in the hot air duct at the guide vane, reducing the dehumidifier's operating efficiency. Summary of the Invention

[0004] Therefore, the present invention provides a dehumidifier with independent cold air duct and hot air duct, which can solve the technical problem in the prior art where a guide plate is used to separate an air duct shell to form a cold air duct and a hot air duct, and the cold air in the cold air duct and the hot air in the hot air duct form heat transfer at the guide plate, which reduces the operating efficiency of the dehumidifier.

[0005] To address the aforementioned problems, this invention provides a dehumidifier with independent cold air ducts and hot air ducts, comprising: a dehumidifier housing, the dehumidifier housing having an accommodating space; the accommodating space housing an evaporator, a condenser, a water tray, and a centrifugal volute, a cross-flow volute, and a motor bracket located above the water tray; the centrifugal volute housing housing a centrifugal fan assembly; the motor bracket having a motor mounting blockage plate that blocks the motor mounting hole of the centrifugal volute; a first drive motor of the centrifugal fan assembly connected to the motor mounting blockage plate; the evaporator located at the air inlet of the centrifugal volute; the condenser spaced apart from the evaporator; and the motor bracket having a sidewall extending toward the condenser, the sidewall forming a blockage on opposite sides of the condenser; the cross-flow volute housing mounted on the top surface of the sidewall; and the bottom surface of the sidewall abutting against the water tray.

[0006] In some embodiments, the motor mounting plate has a heat insulation layer on the side facing the sidewall.

[0007] In some embodiments, the insulation layer is insulation foam.

[0008] In some embodiments, there is a gap between the centrifugal volute and the cross-flow volute.

[0009] In some embodiments, the interval has a connecting structure, one end of which is connected to the centrifugal volute, and the other end of which is connected to the cross-flow volute.

[0010] In some embodiments, the air outlet duct section of the centrifugal volute and the air outlet duct section of the cross-flow volute form a Y-shape in their airflow direction.

[0011] In some embodiments, the dehumidifier housing includes a rear housing, a front housing, a side housing located between the front housing and the rear housing, and a top housing located at the top of the front housing and the rear housing. The top housing is provided with a cold air outlet and a hot air outlet. The rear housing is provided with a cold air inlet corresponding to the evaporator, and the side housing is provided with a hot air inlet corresponding to the condenser.

[0012] In some embodiments, the hot air outlet is provided with an air guide assembly; and / or, the cold air outlet is connected to an exhaust hose assembly.

[0013] In some embodiments, the exhaust hose assembly includes a fitting and a hose connected to a first end of the fitting, the second end of the fitting being snap-fitted to the cold air outlet.

[0014] In some embodiments, a protective net is provided inside the hot air outlet, and the protective net is located on the side of the air guide assembly near the cross-flow volute.

[0015] The present invention provides a dehumidifier with independent cold air duct and hot air duct, which has the following beneficial effects:

[0016] The motor bracket has a motor mounting plate and two side walls. On the one hand, it forms a separation structure between the hot air duct and the cold air duct, and at the same time, it serves as a mounting carrier for the centrifugal volute and the cross-flow volute. This makes the dehumidifier structure design reasonable and compact. On the other hand, the invention utilizes the spatial spacing of the first drive motor to make the distance between the heated airflow in the hot air duct and the cooled airflow in the cold air duct larger, which greatly reduces the heat transfer of the cold airflow at the motor bracket, thereby improving the operating efficiency of the cold air type dehumidifier and reducing the power consumption of the equipment.

[0017] The centrifugal volute and the cross-flow volute do not come into direct contact. With this design, the hot air duct and the cold air duct only have contact at the motor mounting plate. As mentioned earlier, the space occupied by the motor and the design of the heat insulation layer reduce the probability of heat transfer between the hot air and cold air in the corresponding part. The aforementioned spacing further reduces the probability of heat transfer between the hot air in the hot air duct and the cold air in the cold air duct at the cross-flow volute and the centrifugal volute, thereby further improving the operating efficiency of the dehumidifier.

[0018] By setting a connecting structure between the centrifugal volute and the cross-flow volute, the centrifugal volute and the cross-flow volute can be connected into a whole, which improves the positional reliability of the centrifugal volute and the cross-flow volute. At the same time, it can also reduce the vibration noise caused by the excitation of the corresponding volute by the centrifugal fan or the cross-flow fan during operation, thus facilitating the silent design of the dehumidifier.

[0019] The Y-shaped air outlet duct structure design allows two airflows of different temperatures to be guided to larger and different areas, preventing the mixing of the two temperatures and thus reducing the cooling (local cooling) or drying (hot air) effect.

[0020] Both the cold air outlet and the hot air outlet are located on the top casing, thus achieving upward airflow of both hot and cold air. It is worth noting that the purpose of the hot airflow in the dehumidifier is to dry clothes during the dehumidification process. This differs from the purpose of directing hot air downwards in conventional air conditioners to achieve carpet-like airflow. This allows the upward-directed hot air in this invention to match the hanging position of the clothes, facilitating drying. Meanwhile, the upward-directed cold air outlet utilizes the high density of the cold airflow to achieve a shower-like airflow, which improves the user's cooling experience.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0050] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0051] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0052] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0053] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0054] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0055] See also Figure 1 and Figure 12 As shown, according to an embodiment of the present invention, a dehumidifier with independent cold air ducts and hot air ducts is provided, comprising: a dehumidifier housing, wherein the dehumidifier housing has an accommodating space; the accommodating space is provided with an evaporator 101, a condenser 102, a water tray 2, and a centrifugal volute 31, a cross-flow volute 41, and a motor bracket 5 located above the water tray 2; a compressor 103 and a corresponding water tank 104 are assembled in the area below the water tray 2, wherein the water tank 104 is used to store the condensate collected on the water tray 2, and the water tank 104 is preferably assembled in the area below the accommodating space in a push-pull manner. It is understood that the water tray 2 in the present invention will... The accommodating space is divided into an independent upper region and a lower region (i.e., no airflow). The water tray 2 is positioned above the compressor 103, allowing some of the condensate in the water tray 2 to be evaporated using the heat generated by the compressor 103, thus reducing the processing frequency of the water tank 104. A centrifugal fan assembly is installed inside the centrifugal volute 31. The motor bracket 5 has a motor mounting block plate 51 that seals (e.g., by means of a snap-fit ​​structure and bolts) the motor mounting holes of the centrifugal volute 31. The first drive motor 32 of the centrifugal fan assembly is connected to the motor mounting block plate 51. The evaporator 101 is located at the air inlet of the centrifugal volute 31. See details... Figure 6 As shown, the centrifugal fan 33 is installed on the side of the first drive motor 32 away from the motor bracket 5, so that the airflow drawn in by the centrifugal fan 33 from the air inlet of the centrifugal volute 31 can be quickly blown out after heat exchange and cooling in the evaporator 101. The condenser 102 is spaced apart from the evaporator 101, and the motor bracket 5 also has a sidewall 52 extending toward the condenser 102. The sidewall 52 can form a seal on the opposite sides of the condenser 102. The cross-flow volute 4 A bracket is mounted on the top surface of the side wall 52, and the bottom surface of the side wall 52 abuts against the water receiving tray 2. In some embodiments, the bottom surface of the side wall 52 and the water receiving tray 2 are reliably connected by a snap-fit ​​structure. Thus, the motor mounting plate 51 of the aforementioned motor bracket 5, the two side walls 52, and the water receiving tray 2 together form the lower region of the hot air duct, while the cross-flow volute 41 forms the upper region of the hot air duct, and the aforementioned centrifugal volute 31 and the motor mounting plate 51 form the cold air duct.

[0056] In this technical solution, the motor bracket 5 has a motor mounting plate 51 and two side walls 52. On the one hand, it forms a separation structure between the hot air duct and the cold air duct, and at the same time, it serves as a mounting carrier for the centrifugal volute 31 and the cross-flow volute 41. This makes the dehumidifier structure design reasonable and compact. On the other hand, the invention utilizes the spatial spacing of the first drive motor 32 to make the distance between the heated airflow in the hot air duct and the cooled airflow in the cold air duct larger, which greatly reduces the heat transfer of the cold airflow at the motor bracket 5, thereby improving the operating efficiency of the cold air type dehumidifier and reducing the power consumption of the equipment.

[0057] Furthermore, the cross-flow fan assembly and centrifugal fan assembly in this invention are staggered vertically, which further reduces the size of the dehumidifier and occupies less space. The centrifugal fan assembly has a larger air volume and lower noise, and blows out a larger amount of cool air with a stronger feel.

[0058] See Figure 6 As shown, after the indoor air enters the evaporator 101 through the cold air inlet 13 and is cooled by heat exchange, since the centrifugal fan assembly is axially inlet and tangentially outlet, most of this cold airflow will be discharged by the centrifugal volute 31, and only a small portion of the cold airflow will enter the location of the first drive motor 32 and come into contact with the motor mounting plate 51. Therefore, the proportion of heat transfer between the hot airflow in the hot air duct and the motor mounting plate 51 is extremely low, and can even be ignored.

[0059] It should be noted that, from a top-down view of the usage position, the projection of the motor mounting plate 51 and the two side walls 52 forms a U-shape with an opening facing the condenser 102, thus forming the lower part of the hot air duct together with the water tray 2.

[0060] In a more preferred embodiment, the motor mounting plate 51 is provided with a heat insulation layer 53 on the side facing the side wall 52.

[0061] In this technical solution, by setting up a heat insulation layer 53, heat transfer through the motor mounting plate 51 is further isolated, which further reduces the probability of heat exchange between cold air and hot air before they are blown out.

[0062] The aforementioned heat insulation layer 53 can be implemented in various ways. In some embodiments, the heat insulation layer 53 is heat insulation foam, which can be formed by blow molding on the side of the motor mounting plate 51 facing the condenser 102. The forming process is simple, convenient, and has a low cost.

[0063] See further Figure 6 As shown, there is a gap between the centrifugal volute 31 and the cross-flow volute 41.

[0064] In this technical solution, the centrifugal volute 31 and the cross-flow volute 41 do not directly contact each other. With this design, the hot air duct and the cold air duct only have contact at the motor mounting plate 51. As mentioned above, the heat transfer probability between the hot air and cold air at this location is reduced by the motor's occupancy and the design of the insulation layer 53. The aforementioned spacing further reduces the probability of heat transfer between the hot air in the hot air duct and the cold air in the cold air duct at the cross-flow volute 41 and the centrifugal volute 31, thereby further improving the dehumidifier's operating efficiency.

[0065] In some embodiments, the interval has a connecting structure 6, one end of which is connected to the centrifugal volute 31 and the other end of which is connected to the cross-flow volute 41. The connecting structure 6 can be two interlocking snap-fit ​​structures, or it can be two support reinforcement arms that can be bolted together.

[0066] In this technical solution, by setting a connecting structure 6 between the centrifugal volute 31 and the cross-flow volute 41, the centrifugal volute 31 and the cross-flow volute 41 can be connected into a whole, which improves the positional reliability of the centrifugal volute 31 and the cross-flow volute 41. At the same time, it can also reduce the vibration noise caused by the excitation of the corresponding volute by the centrifugal fan or cross-flow fan during operation, thus facilitating the silent design of the dehumidifier.

[0067] In some embodiments, the airflow directions of the outlet section of the centrifugal volute 31 and the outlet section of the cross-flow volute 41 form a Y-shape. That is, as the airflow direction changes, the distance between the outlet sections of the centrifugal volute 31 and the cross-flow volute 41 increases, i.e., the gap width mentioned above increases. It should be noted that the Y-shape formed by the airflow directions of the outlet sections of the centrifugal volute 31 and the cross-flow volute 41 increases the gap between the two outlet sections. This gap forms a heat insulation cavity, further reducing energy loss caused by heat conduction between the hot and cold air ducts. In a more preferred embodiment, heat insulation material is provided within this gap.

[0068] It is understood that the airflow in the centrifugal volute 31 and the cross-flow volute 41 of this invention is cold air and hot air. The Y-shaped air outlet structure design can guide the two airflows of different temperatures to larger and different areas, preventing the mixing of the two temperatures and thus reducing the cooling (local cooling) or drying (hot air) effect.

[0069] In some implementations, see reference Figures 1 to 3As shown, the dehumidifier housing includes a rear shell 151, a front shell 152, a side shell 153 (including the left and right sides) located between the front shell 152 and the rear shell 151, a top shell 154 located at the top of the front shell 152 and the rear shell 151, and a base 155 located at the bottom of the front shell 152 and the rear shell 151. That is, the aforementioned rear shell 151, front shell 152, side shell 153, top shell 154 and base 155 are assembled adjacent to each other to form a roughly cubic structure with the aforementioned accommodating space. Of course, in a more preferred embodiment, the aforementioned rear shell 151, front shell 152, and side shell 153 are integrally formed housings. The top shell 154 is provided with a cold air outlet 11 and a hot air outlet 12. The rear shell 151 is provided with a cold air inlet 13 corresponding to the evaporator 101. The side shell 153 is provided with a hot air inlet 14 corresponding to the condenser 102.

[0070] In this technical solution, both the cold air outlet 11 and the hot air outlet 12 are located on the top shell 154, thereby achieving upward airflow of both hot and cold air. It is worth noting that the purpose of the hot airflow in the dehumidifier is to dry clothes during the dehumidification process. This differs from the purpose of directing hot air downwards in a typical air conditioner to achieve carpet-like airflow. This allows the upward-directed hot air in this invention to match the hanging position of the clothes, facilitating drying. Meanwhile, the upward-directed cold air outlet 11 utilizes the high density of the cold airflow to achieve shower-like airflow, which improves the user's cooling experience.

[0071] In addition, in this invention, the cold air inlet 13 is located at the rear shell 151, while the hot air inlet 14 is located on the side shell 153. Specifically, the side shell 153 includes a left shell and a right shell. There are two hot air inlets 14, located on the left and right shells respectively. The front shell 152 does not have any corresponding air vents, which improves the overall aesthetic appearance of the dehumidifier. The aforementioned cold air inlet 13 contains a cold air filter 131 to filter the air entering the evaporator 101, removing dust and other foreign matter to prevent the evaporator 101 from becoming dirty. The hot air inlet 14 contains a hot air filter 141 to filter the air entering the condenser 102, preventing the condenser 102 from becoming dirty. The aforementioned cold air filter 131 and hot air filter 141 are detachably assembled into their respective inlet structures, for example, by insertion, to facilitate timely cleaning of the filters.

[0072] In order to make necessary adjustments to the drying angle, in some embodiments, the hot air outlet 12 is provided with an air guide assembly 121. The aforementioned air guide assembly 121 includes an air guide plate (not labeled in the figure) and an air guide plate rotation motor (not labeled in the figure) for driving the air guide plate to rotate. Under some working conditions, the air guide plate can also be used for sweeping air, so that the hot air flow can be sent to a larger space, which is beneficial for drying a large number of hanging clothes in a single cycle.

[0073] Understandably, when the dehumidifier is not running, the air guide assembly 121 can also close the hot air outlet 12 to prevent external dust from entering the interior of the cross-flow volute 41 through the hot air outlet 12, thus ensuring the cleanliness of the interior of the cross-flow volute 41 and the cross-flow fan 42 installed inside it, and reducing subsequent maintenance and operation costs.

[0074] In another preferred embodiment, a protective net 122 is provided inside the hot air outlet 12, and the protective net 122 is located on the side of the air guide assembly 121 close to the cross-flow volute 41. The aforementioned protective net 122 can be a metal mesh with a large mesh count or other types of mesh structure. In terms of its setting position, it should not obstruct the opening and closing of the air guide assembly 121, nor should it block the sweeping of the air guide plate.

[0075] In this technical solution, a protective net 122 is installed inside the hot air outlet 12 and on the side of the air guide assembly 121 near the cross-flow volute 41. This can prevent foreign objects such as clothes from falling into the cross-flow volute 41 through the hot air outlet 12 during the drying process, and can also prevent foreign objects from falling into the machine and causing damage.

[0076] In a preferred embodiment, the cold air outlet 11 is connected to an exhaust hose assembly 111, that is, the cold air flow sent out by the cold air outlet 11 is guided to the target area through the exhaust hose assembly 111, thereby achieving cooling of a small area, meeting the user's personalized cooling needs, and improving the user experience.

[0077] In a preferred embodiment, the exhaust hose assembly 111 includes a pipe connector 1111 and a hose 1112 connected to the first end of the pipe connector 1111. The hose 1112 is stretchable and bendable, and adjusting the outlet direction of the hose 1112 can control the direction of the cold air. The second end of the pipe connector 1111 is snap-fitted to the cold air outlet 11. Specifically, see... Figure 7As shown, the first end of the pipe connector 1111 has a circular hole structure with an internal thread 1114 formed on the inner wall of the hole. This threaded connection allows the user to select hoses 1112 of different lengths according to their needs. The second end of the pipe connector 1111 is shaped to match the cold air outlet 11. For example, when the cold air outlet 11 is rectangular, the second end of the pipe connector 1111 has a rectangular opening, ensuring a complete seal between the two. Multiple hooks 1113 extending towards the cold air outlet 11 are provided at the edge of the rectangular opening. These hooks 1113 form a snap-fit ​​connection with the edge of the cold air outlet 11, enabling quick assembly of the exhaust hose assembly 111 and the cold air outlet 11.

[0078] The aforementioned top shell 154 is connected to a handle 105, which facilitates the user to carry and move the dehumidifier by hand; in another preferred embodiment, the aforementioned base 155 is connected to a roller 1551 on the bottom side wall, which allows the user to move the dehumidifier flexibly and conveniently.

[0079] The dehumidifier provided in this invention can blow cold air and hot air simultaneously while dehumidifying. Cold air is delivered from the cold air duct, and hot air is delivered from the hot air duct. Furthermore, the cold and hot air can be blown in different directions. In damp and cold weather, the hot air can be directed towards the human body or the area where clothes are hung, and the air guide plate controls the hot air to blow towards the designated area, achieving functions such as heating or drying clothes. In damp and hot weather, the cold air can be directed towards the human body, and the flexible hose in the exhaust duct assembly adjusts the direction of the cold air, blowing towards the designated area to achieve cooling. This invention can achieve the purpose of localized cooling and heating by controlling the direction of cold and hot air, improving user experience and comfort.

[0080] Figure 11 The airflow principle of the dehumidifier on the cold air side in this embodiment of the invention: see reference [link to relevant documentation]. Figure 6 As shown, the centrifugal fan 33 rotates on one side of the rear shell 151, creating negative pressure in the cold air duct (i.e., the duct space formed by the aforementioned motor mounting plate 51 and centrifugal volute 31). Indoor air enters through the cold air inlet 13 and passes through the evaporator 101. Since the surface of the evaporator 101 is at a low temperature, excess moisture in the indoor air will condense here and become condensate, which enters the water collection tray 2 and flows into the water tank 104, thus achieving dehumidification. After dehumidification, the air becomes dry and cold air, which is blown by the centrifugal fan 33 to the cold air outlet 11 and then blown to the area where the user needs localized cooling through the connected exhaust hose assembly 111.

[0081] Figure 12 The airflow principle of the dehumidifier on the hot air side in this embodiment of the invention is as follows: (Refer to...) Figure 6As shown, the cross-flow fan 42 on one side of the front shell 152 (i.e., the panel) rotates, creating a negative pressure in the hot air duct.
