Description

[Technical Field]

[0002] This utility model relates to the field of clothing care equipment technology, and in particular to a clothing care machine with a fan-assisted air supply structure. [Background Technology]

[0004] With the increasing demand for refined clothing care in modern life, garment care machines integrating multiple functions such as drying, wrinkle removal, sterilization, and deodorization have become widely available in homes. These devices are typically vertical cabinets with a built-in care chamber and an air circulation and treatment system that uses circulated airflow at a specific temperature and humidity to care for the garments. The core components of this system usually include a fan, a heat pump, and air ducts. During operation, air is drawn out of the care chamber, its temperature and humidity are regulated by the heat pump, and then the fan returns it to the care chamber.

[0005] However, existing garment care machines still have room for improvement in terms of the efficiency and adaptability of their air circulation systems. First, regarding airflow, traditional designs often provide a relatively fixed or limitedly adjustable airflow. This setting may not achieve optimal efficiency or fully meet the airflow requirements under specific conditions when faced with different care loads (such as differences in the number and thickness of clothes) or specific care programs (such as quick drying versus gentle care), thus limiting the care effect and speed.

[0006] Secondly, in terms of air heating and temperature control, although the heat pump system is the main unit for temperature and humidity regulation, in some scenarios, such as when it is necessary to quickly raise the outlet airflow to a higher temperature or to make immediate and precise temperature adjustments, its response speed and the upper limit of the temperature it can reach may not fully meet the requirements. [Utility Model Content]

[0008] The purpose of this invention is to provide a garment care machine with a fan-assisted air supply structure, which aims to solve the problems of insufficient adaptability of air circulation volume, insufficient heating efficiency and outlet temperature control accuracy of existing garment care machines, as well as the limitations in the overall efficiency and refined control of the fan system.

[0009] This utility model is achieved through the following technical solution:

[0010] A garment care machine with a fan-assisted air supply structure includes a cabinet. The upper part of the cabinet has a care chamber with an air outlet and a return air outlet. A centrifugal fan is located at the bottom of the cabinet below the air outlet. The return air outlet is connected to a return air channel located at the bottom of the cabinet. A heat pump assembly is provided between the centrifugal fan and the return air channel. A heating element is provided at the air outlet of the centrifugal fan. An air supply assembly to increase the air intake volume is provided on the side wall of the casing near its air outlet.

[0011] As described above, a garment care machine with a fan-assisted air supply structure includes an air supply port on the side wall of the centrifugal fan outlet housing. A corresponding air supply plate for controlling the air intake is detachably connected to the air supply port. There is an air supply gap between the air supply plate and the inner wall of the centrifugal fan housing.

[0012] As described above, a garment care machine with a fan-assisted air supply structure is provided at the air outlet to guide the rising airflow from below to the sides to avoid blowing directly onto the garment. The wind deflector includes a wind deflector plate, and multiple connecting parts are evenly arranged around the wind deflector plate. There is a clearance between the wind deflector plate and the bottom of the care chamber to allow the airflow to move laterally from the air outlet.

[0013] In the clothing care machine with a fan-assisted air supply structure described above, the projected area of ​​the baffle plate relative to the bottom of the care chamber is larger than the area of ​​the air outlet.

[0014] As described above, in a garment care machine with a fan-assisted air supply structure, a plurality of first guide ribs are evenly provided on any two opposite sides of one end face of the baffle plate facing the air outlet, and a plurality of second guide ribs are evenly provided on the remaining two opposite sides of the end face.

[0015] In the clothing care machine with a fan-assisted air supply structure described above, the thickness of the baffle plate decreases radially from its center.

[0016] As described above, in a garment care machine with a fan-assisted air supply structure, the wind deflector is provided with multiple pressure relief holes.

[0017] As described above, a garment care machine with a fan-assisted air supply structure has a connecting flange between the centrifugal fan and the air outlet. The shape of the connecting flange is adapted to the air outlet. The connecting flange is detachably fixed to the edge of the air outlet housing of the centrifugal fan and connects the centrifugal fan to the air outlet.

[0018] As described above, in a garment care machine with a fan-assisted air supply structure, the connecting flange is provided with multiple assembly parts that can be disassembled and fixed in conjunction with the connecting part, for installing and fixing the windproof device.

[0019] As described above, in a garment care machine with a fan-assisted air supply structure, the heat pump assembly includes a heat exchange chamber adjacent to the centrifugal fan, a heat exchange base connected below the heat exchange chamber, a condenser and an evaporator mounted on the heat exchange base, the condenser adjacent to the heat exchange chamber, a return air duct adjacent to the evaporator, and a compressor connected to the condenser and evaporator respectively via pipes.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. By installing an air supply component on the side wall of the casing near the centrifugal fan outlet, this invention can directly and effectively increase the total amount of air entering the fan and ultimately delivered into the care chamber. A larger circulating air volume means that the drying, deodorizing, or wrinkle-removing processes for clothing can be completed more quickly, thus significantly improving the working efficiency and overall care performance of the garment care machine.

[0022] 2. By placing the heating element at the outlet of the centrifugal fan, direct, end-point heating of the airflow entering the nursing room is achieved. This layout ensures that heat is rapidly transferred to the airflow, with a fast response time, enabling quick and precise control of the required outlet temperature for nursing care. This is particularly advantageous for nursing procedures that require rapid temperature increases, improving heating efficiency and the accuracy of temperature control. [Attached Image Description]

Detailed Implementation Methods

[0038] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0039] Please see Figures 1 to 12 This embodiment provides a garment care machine with a fan-assisted air supply structure. The garment care machine includes a vertical cabinet 10, with a care chamber 11 on the upper part for accommodating garments. The bottom of the care chamber 11 has an air outlet 12 for blowing out the treated airflow and an air return outlet 13 for recovering the airflow.

[0040] An air circulation and treatment system is installed at the bottom of the cabinet 10. This includes a centrifugal fan 14 located below the air outlet 12, which drives the airflow. The return air outlet 13 is connected to the air handling unit via a return air duct 15, which is also located at the bottom of the cabinet 10.

[0041] Air handling is handled by a heat pump assembly 16, which includes a heat exchange chamber 161 adjacent to the air inlet side of the centrifugal fan 14; a heat exchange base 162 connected below the heat exchange chamber 161; a condenser 163 mounted on the heat exchange base 162 and adjacent to the heat exchange chamber 161; an evaporator 164 also mounted on the heat exchange base 162 but adjacent to the return air duct 15; and a compressor 165 connected to the condenser 163 and the evaporator 164 via pipes, forming a complete cooling / heating cycle. The air circulation path of this system is roughly as follows: air enters the return air duct 15 from the nursing room 11 through the return air inlet 13, flows through the evaporator 164 for cooling and dehumidification, then flows through the condenser 163 for heating, and then enters the heat exchange chamber 161. After being pressurized by the centrifugal fan 14, it is then returned to the nursing room 11 through the air outlet 12. It should be noted that the above-mentioned air circulation and treatment system is existing technology, so it will only be briefly described and will not be elaborated further, as those skilled in the art should know.

[0042] Unlike existing designs, one improvement in this embodiment lies in the deep optimization of the centrifugal fan 14 itself and its operating mode. Specifically, a heating element 19 is installed at the air outlet of the centrifugal fan 14, that is, at the position just before the airflow pressurized by the fan impeller leaves the fan and enters the air outlet 12. This heating element 19 can be a PTC heater or an electric heating wire, and its position is close to the area where the airflow leaves the fan and enters the air outlet 12, enabling it to heat the output airflow.

[0043] Another significant improvement is the addition of a makeup air assembly on the side wall of the centrifugal fan 14 near its outlet end, designed to significantly increase the intake air volume. This makeup air assembly includes a makeup air inlet 20 on the side wall of the centrifugal fan 14 near the outlet port, designed to ensure that the supplementary air can be efficiently mixed with the mainstream air or directly and effectively acted upon by the fan impeller. Crucially, a makeup air plate 21 for precise control of the makeup air volume is detachably connected to the makeup air inlet 20. The connection method can be a snap-fit ​​connection, a screw connection, etc. If a snap-fit ​​connection is used, locking holes can be made around the perimeter of the makeup air inlet 20, and corresponding snaps can be provided on the makeup air plate 21 to achieve a detachable connection.

[0044] There is a certain air supply gap between the air supply plate 21 and the inner wall of the centrifugal fan 14 housing or the periphery of the air supply port 20, to control the actual air supply volume through the air supply port 20. Additionally, in some possible embodiments, the air supply plate 20 itself can also actively adjust the actual air supply volume through the air supply port 20 through specific structural designs such as sliding, rotation, or variable openings. This design allows the equipment to introduce additional supplementary air from the internal space at the bottom of the garment care machine housing according to operational needs.

[0045] Based on the above improvements, the air circulation and processing path of the garment care machine in this embodiment has been further optimized and refined. First, the air in the care chamber 11, as the main circulating airflow, is drawn in through the return air inlet 13 and enters the core area of ​​the heat pump assembly 16 through the return air channel 15. Here, according to the preset care program, the air flows through the evaporator 164 for cooling and dehumidification, then flows through the condenser 163 for heating. The pre-treated air then enters the heat exchange chamber 161, and is subsequently guided to the air intake area of ​​the centrifugal fan 14. Parallel to this main circulation is the activation of the makeup air path. During the above processing of the main circulating airflow, the makeup air assembly located on the side wall of the centrifugal fan 14 housing (near its air outlet) also operates synchronously. Through the setting of the makeup air inlet and makeup air plate 21, an appropriate amount of makeup air can be introduced from the makeup air inlet 20. This newly added airflow is effectively mixed with the main circulating airflow from the heat pump assembly 16 inside the centrifugal fan 14 housing, especially in the area where its impeller is about to do work on the airflow.

[0046] The mixed airflow is then powerfully driven by the impeller of centrifugal fan 14, resulting in significant pressurization. Just before exiting the outlet of centrifugal fan 14 and entering outlet 12, this pressurized mixed airflow undergoes final heating via heating element 19, ensuring it reaches or is maintained at the ideal temperature required for care. Finally, this optimized airflow, precisely temperature-controlled and with adequately replenished airflow, is reintroduced into the interior of the care room 11 through outlet 12, providing comprehensive and gentle care for the hanging garments.

[0047] It is worth emphasizing that although the heat pump assembly 16 itself has the ability to heat the circulating air, the additional heating element 19 installed at the outlet port of the centrifugal fan 14 not only serves as an important supplementary heating method, but also enables rapid response and fine adjustment of the outlet airflow temperature, and can even meet the high-temperature requirements of certain special care procedures. The addition of the make-up air assembly can increase the total circulating air volume, thereby significantly improving the overall care efficiency and user experience.

[0048] However, simply providing the enhanced circulating airflow may result in the airflow being too concentrated and intense, directly upward from the air outlet 12, potentially damaging clothing or causing uneven care. To address this problem, this embodiment further includes a wind deflector 17 at the air outlet 12.

[0049] This air deflector 17 is located on the airflow path rising from the centrifugal fan 14 below through the air outlet 12. Its physical structure can be designed as an upwardly protruding conical cover, a ring-shaped component with guide ribs, or a flat plate at a specific angle, etc., to effectively intercept the vertically upward, concentrated airflow and forcibly guide it to the sides of the air outlet 12 or diffuse it upward at a certain angle, so that it finally enters the nursing room 11 in a more diffuse state.

[0050] By installing the wind deflector 17 at the air outlet 12, the high-speed airflow (whether hot or cold) driven by the centrifugal fan 14 and processed by the heat pump assembly 16 no longer directly and violently impacts the hanging clothes, greatly reducing the risk of physical damage, thermal damage or deformation to delicate or sensitive fabrics such as silk and wool.

[0051] Furthermore, the wind deflector 17 transforms the originally concentrated rising airflow at the air outlet 12 into a more diffused airflow that spreads outwards. This change in airflow pattern directly contributes to a more uniform and seamless airflow distribution throughout the entire care room 11. This allows the heat, dry air, or other care media generated by the heat pump assembly 16 to more evenly cover and penetrate all parts of the garment, significantly improving the uniformity and overall efficiency of the drying, wrinkle removal, sterilization, and deodorization processes.

[0052] Furthermore, as a preferred embodiment of this solution and not a limitation, the wind deflector 17 includes a wind deflector 171. This wind deflector 171 can be designed as circular, square, or other shapes suitable for covering the air outlet 12, and its material can be heat-resistant plastic or metal. To stably fix the wind deflector 171 above the air outlet 12 and to achieve lateral airflow guidance, a plurality of connecting portions 172 are evenly provided on the periphery of the wind deflector 171, i.e., its edge portion. These connecting portions 172 can be short columns, L-shaped brackets, clips, or reinforcing ribs extending from the edge of the wind deflector, etc. One end of them is connected to the edge or lower surface of the wind deflector 171, and the other end is fixed to the bottom surface of the care room 11, or fixed to the structural members around the air outlet 12. Supported by the connecting portions 172, a deliberately reserved clearance of a specific height is formed between the wind deflector 171 and the bottom of the care room 11 or the air outlet structure it covers, throughout the entire periphery of the wind deflector 171. This gap ensures a passage for airflow.

[0053] During operation, the rising airflow from the air outlet 12 first impacts the lower surface of the baffle 171 and is blocked, preventing it from continuing to blow vertically upwards onto the clothing. Because the vertical path is blocked, the airflow is forced to flow laterally along the lower surface of the baffle 171. Finally, the airflow diffuses evenly from the edge of the baffle 171 outwards through the clearance between the periphery of the baffle 171 and the bottom of the care room 11, entering the main space of the care room 11. The even distribution of the connecting parts 172 helps ensure that the clearance is continuous in the circumferential direction and has a substantially uniform height, thus promoting a relatively even airflow from all sides.

[0054] Furthermore, the geometry and size of the baffle 171 are designed such that its projected area on the bottom plane of the nursing room 11 is larger than the opening area of ​​the air outlet 12 directly below it. For example, if the air outlet 12 is a circular opening with a diameter of D, then the baffle 171 can be circular, but its diameter d must be larger than the diameter D of the air outlet 12. Essentially, when viewed vertically downwards from directly above the air outlet 12, the outline of the baffle 171 completely covers and extends beyond the outline of the air outlet 12.

[0055] Because the baffle 171 is larger than the air outlet 12, it ensures that all airflow rising from the entire area of ​​the air outlet 12 is intercepted by the lower surface of the baffle 171. No part of the airflow can escape from the edge of the baffle 171 and continue its vertical upward path. This achieves complete blockage of the direct airflow, maximizing the effect of preventing airflow from directly impacting clothing.

[0056] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, a specific flow-guiding structure is provided on the lower surface of the baffle 171, i.e., the side facing the air outlet 12 and the side where the airflow first impacts. Specifically, on the lower surface of the baffle 171, a plurality of first flow-guiding ribs 173 are evenly distributed along any selected pair of opposite sides, such as the lower surface area corresponding to the front and rear edges. At the same time, on the lower surface of the baffle 171, adjacent to the aforementioned sides, a plurality of second flow-guiding ribs 174 are evenly distributed along the remaining pair of opposite sides, such as the lower surface area corresponding to the left and right edges. It should be noted that, for the sake of clarity in describing the "opposite sides" mentioned above, it is assumed that the baffle 171 in this embodiment has a roughly square or rectangular outline; the definition of two pairs of opposite sides for other shapes of baffles 171 can also be applied according to the actual situation.

[0057] The aforementioned guide ribs are slender strip-shaped structures protruding downwards from the lower surface of the wind deflector 171. They can start from near the center of the wind deflector 171 or a certain specific position and extend in a roughly radial or parallel pattern towards the corresponding edge of the wind deflector 171. Within their respective side regions, the distance between these guide ribs is approximately equal, and they are arranged neatly.

[0058] When airflow rises from the air outlet 12 and impacts the lower surface of the baffle 171, it is forced to flow laterally in all directions, flowing along the channels between these guide ribs. Since the first guide rib 173 and the second guide rib 174 can be designed with different directions or different shapes and structures, they can produce different guiding effects on the airflow passing over them. For example, the first guide rib 173 can be designed to generate a straighter and smoother lateral airflow, while the second guide rib 174 can be designed to introduce a certain rotation, turbulence, or a specific outflow angle. Of course, the second guide rib 174 can also be designed to generate another lateral airflow perpendicular to the direction of the first guide rib 173. By setting first guide ribs 173 and second guide ribs 174 with different structures or functions on different sides of the lower surface of the baffle 171, the basic anti-direct-blow and lateral airflow guidance of the baffle device 17 is further enhanced by adding a means to finely zone and control the characteristics of the lateral outflow airflow, optimizing the airflow organization within the nursing room 11, thereby improving overall nursing performance or achieving specific advanced nursing effects.

[0059] Furthermore, as a preferred embodiment of this solution and not a limitation, the thickness of the wind deflector 171 decreases radially from its center. This means that the wind deflector 171 is thickest in its central region, and its thickness decreases towards its periphery. Compared to a uniformly thick plate with the same center thickness, the thicker central region ensures sufficient structural rigidity to withstand airflow impact, while the thinner edges significantly reduce the amount of material required to manufacture the wind deflector 171, thereby effectively reducing the component's weight and material costs. The gradually thinning shape of the wind deflector 171 from the center to the edge also has a positive impact on airflow guidance. When airflow is forced to turn below the wind deflector 171 and flows out through the surrounding clearances, a gradually thinning, streamlined edge guides the airflow more effectively to smoothly "attach" to the edge surface and turn, compared to a thick, blunt vertical edge. This helps reduce the possibility of severe airflow separation and vortex formation at corners, thereby reducing energy loss and aerodynamic noise. In other words, this thickness distribution facilitates a smooth transition of airflow from vertical ascent to lateral diffusion, helping to form a more ordered and potentially more uniform lateral jet, thereby indirectly enhancing the overall airflow efficiency of the wind deflector 17 and improving the airflow distribution within the nursing room 11.

[0060] Furthermore, as a preferred embodiment of this solution and not a limitation, a plurality of pressure relief holes 175 are formed on the body of the wind deflector 171. These pressure relief holes 175 are channels that penetrate the entire thickness of the wind deflector 171. The location, size, shape, and number of pressure relief holes 175 can be determined according to specific aerodynamic design requirements. For example, they can be concentrated in the area of ​​the wind deflector 171 near the geometric center where the airflow impact pressure is usually the greatest, or they can be evenly distributed on the entire surface of the wind deflector 171, or they can be linearly arranged on one side. The shape of the pressure relief holes 175 can be circular, elongated, or other irregular shapes.

[0061] When a high-speed airflow impacts the lower surface of the baffle 171, a localized high-pressure zone is formed below the baffle. The pressure relief hole 175 allows some gas to "leak" upwards directly from this high-pressure zone, effectively reducing the peak pressure below the baffle 171. This helps reduce the aerodynamic load acting on the baffle 171 and its connecting part 172, improving its structural stability and service life. Simultaneously, the pressure reduction and the avoidance of airflow whistling that might result from complete blockage also help reduce operating noise.

[0062] In addition, although the main purpose of the wind deflector 17 is to prevent strong direct airflow, the pressure relief hole 175 allows a small amount of airflow to flow upward in a dispersed, multi-hole jet form, creating a central upward airflow with a controllable total volume, significantly reduced intensity, and highly diffuse shape. This airflow is relatively gentle, avoiding the impact of the original airflow, but still provides a certain degree of airflow coverage to the central area of ​​the nursing room 11, especially the lower center of the hanging clothes, which helps to initiate and maintain air circulation throughout the nursing room 11 and prevents the formation of a dead zone in the central area.

[0063] Furthermore, to achieve a more regular and reliable connection between the air outlet of the centrifugal fan 14 and the air outlet 12 at the bottom of the nursing room 11, a connecting flange 18 is provided between the two. This connecting flange 18 is a transitional connecting component and can be annular, rectangular, or other shapes that match the contour of the air outlet 12. The lower end of the connecting flange 18 is designed to mate with the edge of the air outlet housing of the centrifugal fan 14 and can be detachably secured by, for example, bolts, clips, or other fasteners.

[0064] Its upper end has a shape and size that precisely matches the air outlet 12 at the bottom of the nursing room 11. It can be inserted into the air outlet 12, flush with it, or cover the edge of the air outlet 12, forming a smooth and well-sealed airflow channel to ensure that the airflow generated by the centrifugal fan 14 can be smoothly introduced into the air outlet 12. In addition, the connecting flange 18 also serves to install and fix the wind deflector 17. The connecting flange 18 has assembly parts 181 corresponding to the number of connecting parts 172 on the wind deflector 17. These assembly parts 181 are used to cooperate with the connecting parts 172 on the wind deflector 17 and achieve detachable fixation. The specific form of the assembly part 181 can be:

[0065] Threaded holes are opened on the inner wall or upper surface of the flange for fixing the connection part 172 by screws;

[0066] The groove or snap-fit ​​structure provided on the flange is used to engage with the corresponding structure on the connecting part 172;

[0067] Locating pins or locating holes provided on the flange are used for precise positioning and to assist in fixing the connection part 172.

[0068] During assembly, the wind deflector 17 is connected to the mounting portion 181 on the connecting flange 18 via its connecting portion 172, thereby being securely and precisely installed and fixed onto the connecting flange 18. Since the connecting flange 18 itself is precisely positioned at the air outlet 12, the wind deflector 17 is stably placed above the air outlet 12, precisely in the path of the rising airflow, effectively performing its functions of preventing direct airflow and guiding airflow.

[0069] Compared to directly fixing the air deflector 17 to the potentially thin or complex floor plate of the nursing room 11, the transition connection via the connecting flange 18 provides stronger support and a more stable fixation, better resisting airflow impact and the effects of long-term use. It also ensures that the center position, height, and angle of the air deflector 17 relative to the air outlet 12 meet design requirements, thereby guaranteeing its optimal airflow guiding performance.

[0070] Working principle of this utility model:

[0071] This embodiment proposes a garment care machine with a fan-assisted air supply structure. A heat pump component provides initial dehumidification and sensible heat gain to the main circulating air. The key innovation lies in the centrifugal fan system: Firstly, an air supply component (including an adjustable air supply inlet and a supply plate) is integrated near the air outlet of the fan casing. This component introduces supplementary airflow from the bottom space of the device, effectively premixing it with the heat pump-treated main airflow before the fan impeller's action zone, aiming to improve the system's total volumetric flow rate and overall heat exchange efficiency. Secondly, an auxiliary heating element (such as a PTC) is connected in series at the centrifugal fan outlet, adjacent to the main air outlet, for rapid final temperature calibration and enhancement of the mixed and pressurized airflow, meeting the needs of different care procedures for precise outlet temperature control or high temperatures.

[0072] Secondly, to address the potential jet impact and uneven distribution issues caused by direct airflow, a special wind deflector was installed at the air outlet at the bottom of the nursing room. This device, through physical interception and aerodynamic guidance, forcibly redirects the high-speed vertical jet output from the centrifugal fan into a diffused flow field that spreads uniformly in all directions. The design details of the wind deflector further enhance its performance: for example, the guide ribs on its lower surface are used to finely control the shape and uniformity of the lateral outflow; the plate adopts a radially decreasing thickness distribution, thicker at the center and thinner at the edges, aiming to optimize structural stiffness, reduce component mass, and improve flow characteristics to reduce aerodynamic losses and noise; the pressure relief holes on the plate help balance the local high pressure below the wind deflector, reduce structural load, and allow a small amount of controllable airflow to penetrate upwards to eliminate the central flow dead zone.

[0073] Finally, the application of the connecting flange ensures an airtight and stable connection between the centrifugal fan outlet and the nursing room outlet, and provides a precise installation reference and support for the wind deflector.

[0074] In summary, this garment care machine achieves synergistic optimization of airflow, temperature, and distribution in the care environment through supplementary airflow enhancement, auxiliary fine heating at the outlet, and airflow reconstruction and diffusion treatment at the outlet. It aims to achieve efficient, uniform care that provides high protection for fabrics.
