Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes drying machines, and in particular to a clothes drying machine air duct structure, an air supply system and a clothes drying machine. BACKGROUND

[0002] Clothes drying machines, as a common household appliance, play an increasingly important role in modern family life. With the improvement of people's living standards and the continuous improvement of the quality of life, the functions and designs of clothes drying machines are also constantly innovating. For example, some smart clothes drying machines have functions such as drying, sterilization, and mite removal, which can effectively remove bacteria and mites on clothes and protect the health of family members.

[0003] Existing clothes drying machines with drying functions can usually only achieve partial area drying. They usually use a flood fan for local drying, and the drying area is small, so they cannot cover the entire area of the clothes drying machine. Therefore, when drying clothes, the clothes need to be hung in a specific location. If you want to increase the drying area, you need to increase the number of fans or use a long air duct for air supply, using the long strip-shaped air outlet at the bottom of the long air duct to achieve large-area air supply. However, if you increase the number of fans, the increase in the number of fans will increase the weight and component cost of the clothes drying machine. If you use a long air duct directly for air guidance, the air outlet direction of the long air duct is single, and the drying area is limited, which can cause the problem of not being able to dry the clothes evenly.

DETAILED DESCRIPTION

[0040] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects reached more clear, the technical solutions of the embodiments of the present application are described in further detail below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0041] In the description of the present application, unless otherwise explicitly specified and limited, the terms “connected”, “connected”, “fixed” should be understood in a broad sense, for example, can be fixedly connected, or can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium, or can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] In the present application, unless specifically stated and limited otherwise, a first feature is "on" or "under" a second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "over" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher in horizontal height than the second feature. The first feature "under", "below" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower in horizontal height than the second feature.

[0043] Clothes drying machine, as a common household appliance, plays an increasingly important role in modern family life. With the improvement of people's living standards and the continuous improvement of the quality of life, the function and design of clothes drying machine are also constantly innovating. For example, some intelligent clothes drying machines have the functions of drying, sterilization, and mite removal, which can effectively remove bacteria and mites on clothes and protect the health of family members.

[0044] The existing clothes drying machine with drying function can usually only realize partial area drying, which usually uses a stream fan for local drying. The drying area is small and cannot cover the entire area of the clothes drying machine. Therefore, when drying clothes, the clothes need to be hung at a specific location. If you want to increase the drying area, you need to increase the number of fans or use long air ducts for air supply. The long air outlet at the bottom of the long air duct realizes large-area air outlet. However, if the fan is increased, the increase of the fan will increase the weight and component cost of the clothes drying machine; if the long air duct is directly used for air guiding, due to the single air outlet direction of the long air duct, the limitation of the drying area is relatively large, which will cause the problem that the clothes cannot be fully and evenly dried.

[0045] In order to overcome the above technical problems, a wind channel structure of a clothes drying machine is provided.

[0046] Specifically, the wind channel structure of the present embodiment is applied to a clothes drying machine with drying function. Referring to Figure 11 , the clothes drying machine includes a main machine 4 and a drying rack 5. When installed, the main machine 4 is installed on the ceiling, and the drying rack 5 is suspended below the main machine 4 by a steel wire rope. The main machine 4 has a winch that winds the steel wire rope, realizing the function of automatically driving the drying rack 5 to rise and fall.

[0047] The main machine 4 is also provided with a drying mechanism. The wind channel structure of the present embodiment is applied to the drying mechanism. The drying mechanism also includes a fan 3 and an electric heater. The fan 3 is started to drive the airflow to pass through the electric heater and then be delivered to the wind channel structure. The wind channel structure then guides the hot airflow downward for delivery, realizing the function of drying the clothes hung on the drying rack 5 below.

[0048] The airing rack 5 generally comprises one or two parallel airing rods 51 arranged on a horizontal plane, the airing rods 51 extend along the X direction, and the direction perpendicular to the airing rods 51 is the Y direction. The air duct structure of the embodiment extends along the X direction, so that the air duct structure can guide the hot air flow downward to dry all the clothes hung on the airing rods 51. When the clothes are hung, a clothes hanger 6 is generally used, the clothes hanger 6 is generally hung vertically on the airing rods 51, and the length direction of the clothes hanger 6 is the Y direction. In addition to enabling the hot air flow to blow out uniformly along the X direction, the air duct structure of the embodiment can also uniformly diffuse along the Y direction to cover the entire width of the clothes hanger 6, so as to achieve the purpose of completely and uniformly drying the clothes hung on the airing rods 51. In actual application, one air duct structure is generally arranged above each airing rod 51, that is, two air duct structures are arranged above the two airing rods 51 of the airing rack 5.

[0049] For the convenience of description and understanding, referring to Figure 12 , the area below the airing rods 51 is set as the airing space, the length direction of the airing rods 51 is long, and the length direction of the clothes hanger 6 is wide. Under the guidance of the air duct structure of the embodiment, the air flow blown downward can cover the first airing area E and the second airing area F at the same time, and then completely cover the entire airing space in the Y direction, so as to achieve the purpose of completely drying each piece of clothes.

[0050] In order to achieve the above-mentioned purpose of completely covering the entire airing space in the Y direction, referring to Figures 1-10 , the air duct structure of the embodiment comprises:

[0051] a ventilation duct 1;

[0052] a wind guide member 2 arranged in the ventilation duct 1, the wind guide member 2 extends along the length direction of the airing rods 51; the wind guide member 2 is provided with a plurality of first air outlets 21 and second air outlets 22 arranged alternately, the first air outlets 21 guide the air flow to blow toward the first airing area E, and the second air outlets 22 guide the air flow to blow toward the second airing area F.

[0053] It can be understood that, in the air duct structure of the embodiment, in addition to the air outlets for air outlet in the first air outlets 21 and the second air outlets 22, the ventilation duct 1 should be arranged in a sealed state at other positions to avoid unnecessary air leakage, Figures 1-10 The structure shown is for the convenience of showing the internal structure, so the cover plate at the top of the ventilation duct 1 is not shown. In actual application, the top side of the ventilation duct 1 should be closed by arranging a cover plate.

[0054] The ventilation duct 1 of the embodiment is applied in a clothes drying machine. When the drying function is turned on, hot air flows into the ventilation duct 1 to fill the entire ventilation duct 1, and is blown downward from the first air outlet duct and the second air outlet duct provided on the air guide 2. Since the air guide 2 extends along the length direction (i.e., the X direction) of the drying rod 51, and the first air outlet channel 21 and the second air outlet channel 22 are arranged alternately along the length direction of the air guide 2, the hot air flow can cover the entire drying space in the X direction under the action of the air guide 2. In addition, the first air outlet channel 21 and the second air outlet channel 22 are respectively arranged to guide the air flow to blow toward the first drying area E and the second drying area F, and the two coverage areas are superimposed, i.e., the hot air flow covers the entire drying space in the Y direction, so that the purpose of uniformly drying the clothes hung below the drying rod 51 is achieved. It should be noted that although the first air outlet channel 21 and the second air outlet channel 22 are arranged alternately, and theoretically extend along the X direction, there will be a certain blind area between adjacent first (second) air outlet channels that cannot be covered by the hot air flow, but in actual situation, the air flow will have a horn-shaped diffusion effect after being blown downward, so that the purpose of completely covering the entire drying space can be basically achieved.

[0055] In summary, based on the air duct structure of the clothes drying machine of the embodiment, the air duct structure includes the ventilation duct 1 and the air guide 2 provided in the ventilation duct 1. The air guide 2 is arranged to extend along the length direction of the drying rod 51, and a plurality of first air outlet channels 21 and second air outlet channels 22 are arranged alternately thereon. When the drying function is operated, the first air outlet channel 21 and the second air outlet channel 22 can respectively guide the air flow to blow toward the first drying area E and the second drying area F, which makes the drying space below the drying rod 51 be covered by the drying air flow, and realizes the function of uniformly drying the clothes in the drying space. Based on the diffusion and air guide functions of the air duct structure, a large air outlet area and a uniform air outlet effect can be ensured based on a small number of air fans 3, which realizes the effect of expanding the drying area at a low cost, while ensuring a high heat utilization rate, improving the drying speed and drying uniformity.

[0056] In an embodiment, the length ratio of the first air outlet channel 21 and the second air outlet channel 22 is equal to the width ratio of the first drying area E and the second drying area F.

[0057] Specifically, the first air outlet channel 21 is used to guide the air flow to the first drying area E, and the second air outlet channel 22 is used to guide the air flow to the second drying area F. The length of the first / second air outlet channel is in a positive proportional relationship with the length of the first / second drying area. This can make the larger the drying area, the more air flow is delivered to the area, and ultimately make the entire drying space each area can obtain relatively uniform air flow distribution, which avoids the problem of uneven drying caused by too strong or too weak air flow in a certain area. In addition, by optimizing the air flow distribution, unnecessary heat waste can be reduced. If the air flow of a certain area is too much, it not only speeds up the drying speed of the area, but also may cause heat loss to the surrounding environment. Uniform air flow distribution can ensure that heat is effectively utilized, thereby saving energy.

[0058] In an embodiment, in combination with Figure 4 and Figure 12 , the first air outlet channel 21 has a first air inlet 213 and a first air outlet 214, the first air outlet 214 is arranged downward, and the first air outlet channel 21 includes an air outlet guide area 212 close to the first air outlet 214, the air outlet guide area 212 guides the air flow to blow out vertically downward.

[0059] Specifically, in combination with Figure 12 , in the actual application of the clothes drying machine, taking the center of the drying rack 5 as the reference, the side close to the center of the drying rack 5 is the inner side, and the side away from the center of the drying rack 5 is the outer side. The drying rod 51 will be biased outward relative to the main machine 4 directly above, that is, the first air outlet channel 21 and the second air outlet channel 22 in the air duct structure at the top will be biased inward relative to the drying rod 51. The first air outlet channel 21 in this structure is provided with an air outlet guide area 212 to guide the air flow to blow out vertically downward. In combination with the biasing structure, it can exactly make the air flow cover the first drying area E on the inner side, and at the same time, the first drying area E can be maximized to achieve the purpose of fully utilizing the air flow guided by the first air outlet channel 21. At the same time, since the air flow blows out to the second drying area F on the outer side, it is difficult to avoid that a part of the heat will be quickly diffused to the environment and wasted. In the case of maximizing the first drying area E, the heat distributed by the first drying area E is the most, which can minimize the second drying area F on the outer side, so that the heat distributed by the second drying area F is less, thereby reducing heat loss.

[0060] In an embodiment, the air outlet guide area 212 is in an expanding state from top to bottom.

[0061] The flared state means that the upper caliber of the air outlet guiding area 212 is relatively small, and the lower caliber gradually increases, which is similar to a cone or inverted funnel structure. The flared design can more effectively guide the airflow to flow from the upper part to the lower part, which is more conducive to the diffusion of the airflow in the first drying area E, achieving more uniform drying function. This design helps to reduce airflow turbulence, improve airflow uniformity and efficiency. In addition, in the flared structure, as the caliber increases, the speed of the airflow gradually decreases, and the static pressure gradually increases. This pressure distribution helps to reduce turbulence and noise of the airflow at the outlet, while improving the stability and controllability of the airflow.

[0062] In an embodiment, the air duct 1 is provided with an air inlet 11 on one side, and the air guide member 2 has a windward side facing the air inlet 11 and a leeward side facing away from the air inlet 11, and the first air inlet 213 is arranged on the leeward side.

[0063] When the air duct structure in the embodiments of the present application is applied in a clothes drying machine, the air inlet 11 on one side of the air duct 1 can be connected to the fan 3, and the air guide member 2 is arranged in the air duct 1. The first air inlet 213 of the first air outlet channel 21 is arranged on the leeward side. When the airflow is blown into the air duct 1 from the air inlet 11, the airflow will blow towards the windward side of the air guide member 2, and under the blocking action of the air guide member 2, the airflow will be evenly diffused, so that the airflow can be evenly spread throughout the air duct 1. When the airflow flows upwards around the air guide member 2, it will blow towards the side of the air duct 1 facing the first air outlet 214, then turn back to blow towards the first air outlet 214, and pass through the first air outlet channel 21 of the air guide member 2, and finally blow downwards from the first air outlet 214 on the bottom side. In this embodiment, the uniform air diffusion function of the air duct structure can be realized to evenly diffuse the hot air, achieving the purpose of large-area air outlet drying.

[0064] In an embodiment, the first air outlet channel 21 includes an air inlet turning area 211 and an air outlet guiding area 212, the air inlet turning area 211 is close to the first air inlet 213, the air inlet turning area 211 guides the airflow flowing into the first air inlet 213 to the air outlet guiding area 212, and the air outlet guiding area 212 guides the airflow to blow downwards.

[0065] In the structure of the first air outlet channel 21, the first air inlet 213 is arranged on the leeward side of the air guide member 2, so the airflow enters the air guide member 2 from the first air inlet 213 is horizontal; and the first air outlet 214 is arranged on the bottom side of the air guide member 2, and the air outlet direction is downward blowing, so this scheme sets the air inlet turning area 211 in the first air outlet channel 21 to turn and guide the horizontally entering airflow into the vertical air outlet guiding area 212, which can effectively improve the smoothness of the airflow in the first air outlet channel 21, reduce wind pressure loss, and reduce impact noise.

[0066] In an embodiment, the first air outlet channel 21 has a portion close to the windward side of the air guide 2 as a windward plate 23, and a portion close to the leeward side of the air guide 2 as a leeward plate 24. The windward surface of the windward plate 23 is arc-shaped.

[0067] The arc-shaped design of the windward plate 23 allows the air flow to flow more smoothly when it contacts the windward plate 23, reducing the air resistance caused by the right-angle or acute-angle turning, which helps to improve the flow efficiency of the hot air, so that more hot air can flow faster over the windward plate 23 into the first air outlet channel 21 and blow evenly to the clothes. The arc-shaped design of the windward plate 23 can also reduce the noise caused by the collision or friction of the air flow, which helps to improve the quietness and comfort of the clothes dryer during use.

[0068] In an embodiment, the windward plate 23 includes a planar plate segment 232 and an arc-shaped plate segment 231. The bottom side of the planar plate segment 232 is connected to the ventilation duct 1, and the top side is connected to the arc-shaped plate segment 231. The region of the first air outlet channel 21 corresponding to the arc-shaped plate segment 231 is the air inlet turning area 211, and the region of the first air outlet channel 21 corresponding to the planar plate segment 232 is the air outlet guiding area 212.

[0069] Specifically, the arc-shaped plate segment 231 is on the top, and the planar plate segment 232 is on the bottom. The air flow enters the first air outlet channel 21 through the first air inlet 213 and first encounters the arc-shaped plate segment 231. The arc-shaped inner wall surface of the arc-shaped plate segment 231 can effectively guide and drain the air flow that enters horizontally or obliquely. This design ensures that the air flow can quickly adjust its direction after entering the first air outlet channel 21 and flow downward along the inner wall surface of the arc-shaped plate segment 231. Subsequently, the air flow passes through the region between the planar plate segment 232 and the leeward plate 24, and is further arranged and evenly distributed, and then blows out smoothly downward.

[0070] The design of the arc-shaped plate segment 231 in this embodiment not only helps to guide the direction of the air flow, but also allows the air flow to be more evenly dispersed during the flow process through its arc-shaped surface. When the air flow passes through the arc-shaped plate segment 231, it is more evenly distributed in the region between the planar plate segment 232 and the leeward plate 24, thereby improving the uniformity of the hot air blown out from the first air outlet 214, and also avoiding the loss of air flow speed to ensure sufficient air outlet speed. In addition, the design of the arc-shaped plate segment 231 helps to reduce the noise and vibration caused by the collision or friction of the air flow during the flow process, which helps to improve the quietness and stability of the clothes dryer during use.

[0071] In an embodiment, the side of the arc-shaped plate segment 231 facing the first air outlet channel 21 is a positive circular arc surface.

[0072] The design of the circular arc surface makes the arc-shaped plate segment 231 more smooth when guiding the airflow, reducing the airflow disturbance caused by shape mutation, which helps to ensure that the airflow can flow smoothly along the inner wall surface of the arc-shaped plate segment 231 after entering the first air outlet channel 21, thereby improving the stability and uniformity of the airflow.

[0073] In an embodiment, the top side edge of the back plate 24 is located at the center of the circular arc surface of the arc-shaped plate segment 231.

[0074] Specifically, referring to Figure 5 , the top side edge of the back plate 24 is located at the center of the circular arc surface of the arc-shaped plate segment 231, that is, the distance from each point on the inner circular arc surface of the arc-shaped plate segment 231 to the top side edge of the back plate 24 is the same, that is Figure 5 L1 = L2 in the structure, after the airflow enters through the first air inlet 213, it will pass through a first air outlet channel 21 with a constant width, which can ensure the uniformity of the flow rate after the airflow enters the first air outlet channel 21.

[0075] In an embodiment, the distance between the top side edge of the back plate 24 and the arc-shaped plate segment 231 is not less than 5mm.

[0076] That is, Figure 5 L1 = L2 ≥ 5mm, providing sufficient width can ensure sufficient air volume, thereby ensuring sufficient heat output to dry clothes in a short time.

[0077] In an embodiment, the planar plate segment 232 is inclined relative to the back plate 24, so that the first air outlet channel 21 extends from the top end of the planar plate segment 232 to the first air outlet 214 in a flared state.

[0078] When the airflow flows from the arc-shaped plate segment 231 to the planar plate segment 232, due to the flared design of the first air outlet channel 21, the airflow can gradually spread between the back plates 24 of the planar plate segment 232, thereby guiding the airflow to spread downward and inward, so that the airflow can be more directly blown to the clothes below, so that the airflow can completely cover the inner side area of the first drying area E.

[0079] In an embodiment, the included angle between the planar plate segment 232 and the back plate 24 is 5-15°.

[0080] That is, Figure 5 5° < ∠α < 15° in the structure. Through the inventor's many experiments along, controlling the included angle within this range can achieve diffused airflow while avoiding the problem of excessive diffusion angle leading to heat waste.

[0081] In an embodiment, the windward plate 23 extends in the width direction above the first air outlet 214 by a distance L3, and the first air inlet 213 has a width L4 in the horizontal direction, wherein L3:L4≥1:1.

[0082] That is, Figure 5 L3:L4≥1:1, which can reduce the influence of the first air inlet 213 on the airflow flowing over the top of the windward plate 23, and also reduce the influence of the inertial flow direction caused by the airflow flowing from one side.

[0083] In an embodiment, the second air outlet channel 22 is inclined, and the angle between the air outlet direction of the second air outlet channel 22 and the vertical direction is 35°-43°.

[0084] That is, Figure 5 35°<∠β<45° in the above formula. Through many experiments by the inventor, it has been verified that the angle controlled within this range can effectively cover the second drying area F, and also avoid the problem of heat waste caused by too large diffusion angle.

[0085] In an embodiment, the second air outlet channel 22 includes a second air inlet 221 and a second air outlet 222, the second air inlet 221 is arranged on the windward side, and the second air outlet 222 is arranged downward.

[0086] The second air outlet channel 22 needs to guide the airflow to blow downward obliquely, and the second air inlet 221 is arranged on the windward side, which can conveniently guide the airflow to enter and pass through the second air outlet channel 22, avoiding the problems of wind pressure loss and noise caused by corner impact in the second air outlet channel 22.

[0087] In an embodiment, the length of the first air outlet channel 21 is more than twice the length of the second air outlet channel 22.

[0088] Specifically, by comparing Figures 12-13 , the width of the first drying area E is more than the width of the second drying area F, and the length of the first air outlet channel 21 is more than twice the length of the second air outlet channel 22, which can meet the requirement of uniformly distributing the airflow in the entire drying space.

[0089] On the other hand, a kind of air supply system is provided, comprising the air duct structure.

[0090] Specifically, the air supply system of the embodiment further includes a fan 3, and the air outlet interface of the fan 3 is connected to the air inlet interface 11 of the ventilation duct 1.

[0091] In the working process of the air supply system, the air is conveyed into the ventilation duct 1 under the driving of the fan 3, and is blown out uniformly downward after being diffused by the air guide member 2, so as to achieve the purpose of large-area air drying. The air supply system can ensure a large enough air output area and a uniform air output effect on the basis of using a small number of fans 3, expand the drying area at a low cost, and ensure a high heat utilization rate, improve the drying speed and drying uniformity.

[0092] Specifically, the heater is arranged at the air inlet 11, and the air blown out by the fan 3 can be heated by the heater.

[0093] Preferably, the heater in the embodiment of the application is a PTC heater. The PTC (Positive Temperature Coefficient) heater is a new type of heating element. The working principle of the PTC heater is based on the positive temperature coefficient characteristic of the PTC ceramic material. When the electric current passes through the PTC ceramic, the resistance will increase with the increase of the temperature. When the temperature reaches a certain specific value (Curie temperature), the resistance will increase sharply, and the electric current will decrease, so that the power of the PTC element is automatically adjusted to maintain a constant temperature. The PTC heater has an overheat protection function. When the temperature is too high, the resistance will automatically increase to limit the electric current, preventing the occurrence of overheating.

[0094] Further, the air supply system in the embodiment of the application further comprises a plasma generator arranged in the ventilation duct 1. The plasma generator is a device capable of generating plasma. Plasma is called the "fourth state of matter" and is a highly ionized gas containing a large number of free electrons, ions and other charged particles. Plasma has strong chemical activity and can react with many substances to produce oxidation, reduction, decomposition and other effects. The high-energy electrons and active oxygen ions in the plasma can effectively kill harmful microorganisms such as bacteria, viruses and mites on the clothes.

[0095] In another aspect, an air drying machine is provided, which comprises the air duct structure described above.

[0096] By arranging two air duct structures in the air drying machine, the air drying machine can output drying air around the whole machine, realize the full-area drying function of the air drying machine, and only use two fans 3. The reduction of the number of fans 3 can reduce the overall weight and the cost of parts of the air drying machine. By arranging the two air duct structures in a central symmetry manner, two air duct structures with the same structure can be used, so as to reduce the types of parts and the installation difficulty, and improve the universality of the air duct structure.
