[0001] The present invention relates to the technical field of drying equipment, and particularly relates to a drying device. Background Art

[0002] With the development of the industrialization process and the progress of science and technology, the drying of common items such as intimate clothing, ornaments or children's toys has gradually attracted people's attention, and drying devices for home and business trips have emerged as the times require. The drying devices in the prior art generally include a housing, a heating mechanism and an air outlet mechanism. An air inlet and an air outlet are respectively arranged on the side wall of the housing. The air outlet mechanism can blow air into the housing, and the heating mechanism is arranged between the air outlet mechanism and the air inlet of the housing and can heat the air blown into the housing, so as to dry items such as clothes or ornaments by means of hot air.

[0003] However, after experimental simulation, the applicant found that the air field and temperature field inside such a dryer are uneven, resulting in a high temperature near the air inlet, which is likely to scald clothes or ornaments and make the clothes hard; the temperature in other places is low, and the drying effect is poor. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of uneven air field and temperature field in the drying device in the prior art, so as to provide a drying device that can quickly dry items without damaging them.

[0005] To solve the above problems, the present invention provides a drying device, including: a housing, which forms a drying cavity inside, and the housing is provided with an air inlet, a first air outlet and a second air outlet. The first air outlet is arranged at the upper end of the housing, and the second air outlet is arranged at the lower end of the housing; an air outlet mechanism, which is arranged in the middle of the front side wall of the housing and is adapted to blow air horizontally towards the drying cavity; a heating mechanism, which is arranged inside the housing and is located between the drying cavity and the air outlet mechanism.

[0006] Further, there are a plurality of first air outlets, and the plurality of first air outlets are respectively arranged at the upper ends of the left side wall and the right side wall of the housing.

[0007] Further, there are a plurality of second air outlets, and the plurality of second air outlets are respectively arranged at the lower ends of the left side wall and the right side wall of the housing.

[0008] Further, the air inlet is arranged at the bottom of the housing.

[0009] Further, the drying device further includes a ventilation partition member adapted to separate an assembly cavity and a drying cavity inside the housing. The heating mechanism and the air outlet mechanism are both arranged in the assembly cavity, and the air inlet is communicated with the assembly cavity.

[0010] Further, the ventilation partition protrudes from the middle of the housing, and a diversion slope is formed between the ventilation partition and the side wall of the housing.

[0011] Further, the cross-section of the housing is a rounded rectangle.

[0012] Further, the drying device further includes a first ultraviolet germicidal lamp disposed at the top of the assembly cavity of the housing and a second ultraviolet germicidal lamp disposed at the bottom of the assembly cavity.

[0013] Further, a first receiving convex portion and a second receiving convex portion are respectively formed on the upper side and the lower side of the ventilation partition, and the first ultraviolet germicidal lamp and the second ultraviolet germicidal lamp are respectively disposed in the first receiving convex portion and the second receiving convex portion.

[0014] Further, the drying device further includes an ozone generator disposed in the assembly cavity.

[0015] Further, the air outlet mechanism is disposed on the housing through a fixing bracket, and the ozone generator is disposed between the top wall of the ventilation partition and the top of the fixing bracket.

[0016] Further, the drying device further includes a partition disposed in the housing and above the second air outlet, and the partition is adapted to carry the article to be dried.

[0017] The present invention has the following advantages:

[0018] 1. As can be seen from the above technical solutions, the drying device of the present invention disposes the air outlet mechanism in the middle of the side wall of the housing and enables it to blow air horizontally toward the drying cavity. The air outlets are arranged in two, and are respectively located on the top wall and the bottom wall of the housing. After simulation, when each component is arranged in the above positions, the air blown out from the air outlet mechanism can first blow horizontally to the rear side wall of the housing, and after being blocked by the front side wall, it is dispersed into two equal paths. One path flows leftward along the front wall of the housing, and under the sequential guidance of the front wall, the left side wall and the front side wall of the housing, a vortex air flow is formed on the left side of the drying cavity. The left vortex air flow can be mixed with the newly blown high-temperature fresh air on the left side when passing through the heating mechanism, thereby avoiding local overheating of the temperature in the drying cavity; the upper vortex air flow can flow out through the first air outlet on the top wall of the left side of the housing, and the lower vortex air flow can flow out through the second air outlet on the bottom wall of the left side of the housing;

[0019] The other path flows along the right side of the side wall of the housing, and under the sequential guidance of the right side wall and the front side wall of the housing, a vortex air flow is formed on the right side of the housing. The right vortex air flow can be mixed with the newly blown high-temperature fresh air on the right side when passing through the heating mechanism, thereby avoiding local overheating of the temperature in the drying cavity; the upper vortex air flow can flow out through the first air outlet on the top wall of the right side of the housing, and the lower vortex air flow can flow out through the second air outlet on the bottom wall of the right side of the housing.

[0020] After multiple simulations, the applicant confirmed that during the operation of the drying device of the present invention, the running track of the hot air flow covers the entire drying chamber, with almost no dead corners, and can fully and efficiently dry the clothes, ornaments, etc. placed in the drying chamber. In addition, since the vortex air flow at a lower temperature can continuously mix with the high-temperature new air flow, the temperature field inside the housing can be made more uniform, avoiding local overheating in the drying chamber and scalding the clothes or ornaments. The drying speed of the drying device of the present invention is greatly improved compared with similar products of the same model, and can overcome the defects of uneven air field and temperature field in the drying devices of the prior art.

[0021] 2. The drying device further includes an ultraviolet germicidal lamp. The ultraviolet germicidal lamp can disinfect and sterilize the items in the drying chamber. Since ultraviolet rays can only propagate in a straight line and have limited penetration ability, the housing is preferably provided with a first ultraviolet germicidal lamp and a second ultraviolet germicidal lamp. The first ultraviolet germicidal lamp and the second ultraviolet germicidal lamp are respectively arranged at the top and the bottom of the assembly chamber, and can disinfect and sterilize the items from the upper and lower directions respectively, greatly reducing the dead corners of disinfection and sterilization.

[0022] 3. The drying device preferably further includes an ozone generator arranged in the assembly chamber. The ozone generator can release ozone with strong penetration ability, and the ozone can disinfect and sterilize the items without dead corners under the carrying of the hot air in the drying device. The applicant accidentally found during the experiment that the ozone released by the ozone generator can accelerate the generation of strongly oxidizing hydroxyl radicals under the irradiation of ultraviolet rays, thereby improving the disinfection effect of the drying device. In addition, negative ions such as hydroxyl radicals can also protect the clothes during drying, making the dried clothes not hard and more soft and smooth. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] Figure 1 Side view of the drying device according to an embodiment of the present invention.Figure 2 The Figure 1 cross-sectional view of the drying device shown. Figure 3 The front view of the drying device according to the embodiment of the present invention. Figure 4 The top view of the drying device according to the embodiment of the present invention. As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the present invention relates to a drying device 100, comprising: a housing 1, an air outlet mechanism 3 and a heating mechanism 4. Among them, a drying chamber is formed inside the housing 1. The housing 1 is provided with an air inlet 13, a first air outlet 11 and a second air outlet 12. The first air outlet 11 is arranged at the upper end of the housing 1, and the second air outlet 12 is arranged at the lower end of the housing 1. The air outlet mechanism 3 is arranged in the middle of the front side wall of the housing 1 and is adapted to blow air horizontally towards the drying chamber. The heating mechanism 4 is arranged inside the housing 1 and between the drying chamber and the air outlet mechanism 3. There is no excessive limitation on the position of the air inlet 13. The air inlet 13 can be optionally arranged on the top wall, bottom wall or side wall of the housing 1. For example, in this embodiment, in order to improve the aesthetics of the drying device 100, the air inlet 13 is preferably arranged at the bottom of the housing 1. Among them, the air outlet mechanism 3 is preferably but not limited to a fan. The heating mechanism 4 can be optionally a heating wire or an electromagnetic induction coil, but preferably a PTC heating element with the advantages of small thermal resistance, fast heating, stable temperature and low energy consumption. The PTC heating element has prominent safety performance and will not produce the phenomenon of surface redness of heaters such as electric heating tubes in any application situation, reducing safety hazards such as scalding and fire.

[0036] As can be seen from the above technical solution, the drying device 100 of this embodiment arranges the air outlet mechanism 3 in the middle of the side wall of the housing 1 and enables it to blow air horizontally towards the drying chamber. The air outlets are arranged in two and are respectively located on the top wall and the bottom wall of the housing 1. After simulation, when each component is arranged in the above positions, the air blown out from the air outlet mechanism 3 can first blow horizontally to the rear side wall of the housing 1 and, after being blocked by the front side wall, be dispersed into two equal paths. One path flows leftward along the front wall of the housing 1, and under the sequential guidance of the front wall, left side wall and front side wall of the housing 1, a vortex air flow is formed on the left side of the drying chamber. The left vortex air flow can be mixed with the newly blown high-temperature fresh air on the left when passing through the heating mechanism 4, thus avoiding local overheating of the temperature in the drying chamber; the upper vortex air flow can flow out through the first air outlet 11 at the upper end of the housing 1, and the lower vortex air flow can flow out through the second air outlet 12 at the lower end of the housing 1;

[0037] Another path flows along the right side of the side wall of the housing 1, and successively passes through the right side wall and the front side wall of the housing 1 to form a vortex air flow on the right side of the housing 1. The vortex air flow on the right side can be mixed with the newly blown high-temperature fresh air on the right side when passing through the heating mechanism 4, thus avoiding local overheating of the temperature in the drying cavity. The upper vortex air flow can flow out through the first air outlet 11 at the upper end of the housing 1, and the lower vortex air flow can flow out through the second air outlet 12 at the lower end of the housing 1.

[0038] Therefore, during the operation of the drying device 100 of this embodiment, the running track of the hot air flow covers the entire drying cavity, with almost no dead corners, and can fully and efficiently dry the clothes, ornaments, etc. placed in the drying cavity. In addition, since the relatively low-temperature vortex air flow can continuously mix with the high-temperature fresh air flow, the temperature field in the housing 1 can be made more uniform, avoiding local overheating in the drying cavity and scalding the clothes or ornaments.

[0039] The applicant has confirmed through multiple simulations that the drying speed of the drying device 100 of this embodiment is greatly improved compared with the same type of similar products, and can overcome the defects of uneven air field and temperature field in the existing drying device 100. In order to better verify the drying effect of the drying device 100 of this embodiment, the applicant uses the drying device in the prior art to dry the clothes in the list and compares it with the drying device 100 of this embodiment of the same model, and the recorded data is as follows:

[0040]

[0041] By comparison, the drying device in the prior art works for 6 hours, the weight of the clothes is reduced by 178.9 g, and the drying efficiency is 29.8 g / h. The drying device 100 of this embodiment of the same model works for 4.5 hours, the weight of the clothes is reduced by 174.5 g, and the drying efficiency is 38.7 g / h. In the case of the same model, the drying efficiency of the drying device 100 of this embodiment is increased by 29.9% compared with the drying device in the prior art. It can accelerate the drying speed of the clothes and reduce the energy consumed during the drying process. Among them, the drying efficiency refers to the ratio of the reduced weight of the clothes to the time consumed during the drying process.

[0042] In this embodiment, the first air outlet 11 is preferably multiple. The multiple first air outlets 11 are respectively arranged at the upper ends of the left side wall and the right side wall of the housing 1. This enables the upper vortex air flow on the left side to flow out through the first air outlet 11 at the upper end of the left side wall of the housing 1, and the upper vortex air flow on the right side to flow out through the first air outlet 11 at the upper end of the right side wall of the housing 1.

[0043] There are multiple second air outlets 12. The multiple second air outlets 12 are respectively arranged at the lower ends of the left side wall and the right side wall of the housing 1. The downward vortex air flow on the left can flow out through the second air outlet 12 at the lower end of the left side wall of the housing 1. The downward vortex air flow on the right can flow out through the second air outlet 12 at the lower end of the right side wall of the housing 1. The first air outlet 11 and the second air outlet 12 arranged in this way can lead the air flow to the edge of the drying chamber, avoiding the corners from becoming dead corners and helping to improve the uniformity of the air field in the drying chamber.

[0044] In this embodiment, as Figure 5 shown, the drying device 100 further includes a ventilation partition 5 adapted to separate a drying chamber and an assembly chamber in the housing 1. The heating mechanism 4 and the air outlet mechanism 3 are both arranged in the assembly chamber. The air inlet 13 is preferably communicated with the assembly chamber. The ventilation partition 5 is provided with a wind guide grille, which can separate the heating mechanism 4 from the drying chamber and at the same time guide the air blown out by the air outlet mechanism 3 to flow forward in the horizontal direction, avoiding the items such as clothes and ornaments placed in the drying chamber from contacting the heating mechanism 4 and being scalded. Preferably, mounting ribs are further formed on the ventilation partition 5, and the heating mechanism 4 can be mounted in the housing 1 through the mounting ribs. The ventilation partition 5 can be optionally embedded in the front side wall of the housing 1, but preferably, the ventilation partition 5 is arranged to protrude from the middle of the housing 1 and form a diversion slope 14 between it and the side wall of the housing 1. After simulation, when a diversion slope 14 is formed between the ventilation partition 5 and the side wall of the housing 1, the diversion slope 14 can guide the vortex air flow to flow along the front-back direction of the housing 1 and mix with the high-temperature fresh air blown out by the air outlet mechanism 3. The cross-section of the housing 1 can be rectangular, preferably a rounded rectangle. The rounded corners of the rounded rectangle can more smoothly guide the air flowing along the side wall to form a vortex air flow, avoiding dead corners at the corners and resulting in insufficient drying of the items placed at the corners.

[0045] In this embodiment, the drying device 100 preferably further includes an ultraviolet germicidal lamp. The ultraviolet germicidal lamp can disinfect and sterilize the articles in the drying cavity. Since ultraviolet rays can only propagate in a straight line and have limited penetration ability, therefore, the housing 1 preferably includes a first ultraviolet germicidal lamp 61 and a second ultraviolet germicidal lamp 62. The first ultraviolet germicidal lamp 61 and the second ultraviolet germicidal lamp 62 are respectively arranged at the top and the bottom of the assembly cavity, and can disinfect and sterilize the articles from the upper and lower directions respectively, greatly reducing the dead corners of disinfection and sterilization. The first ultraviolet germicidal lamp 61 and the second ultraviolet germicidal lamp 62 can be optionally arranged in the assembly cavity by means of fasteners, but preferably, in this embodiment, a first receiving convex portion 51 and a second receiving convex portion 52 are respectively formed on the upper side and the lower side of the ventilation partition 5. The first ultraviolet germicidal lamp 61 and the second ultraviolet germicidal lamp 62 are respectively arranged in the first receiving convex portion 51 and the second receiving convex portion 52. This not only reduces the number of parts in the drying device 100, but also improves the assembly strength of the first ultraviolet germicidal lamp 61 and the second ultraviolet germicidal lamp 62, and can make the structure in the assembly cavity more compact.

[0046] Preferably, in order to disinfect and sterilize the articles more thoroughly, the drying device 100 preferably further includes an ozone generator 7 arranged in the assembly cavity. The ozone generator 7 can release ozone with strong penetration ability, and the ozone can disinfect and sterilize the articles without dead corners under the carrying of the hot air in the drying device 100. The applicant unexpectedly found during the experiment that the ozone released by the ozone generator 7 can accelerate the generation of strongly oxidizing hydroxyl groups under the irradiation of ultraviolet rays, thereby improving the disinfection effect of the drying device 100. In addition, negative ions such as hydroxyl groups can also protect the clothes while drying the clothes, making the dried clothes not hard and more soft. The air outlet mechanism 3 is preferably arranged on the housing 1 through a fixing frame 9. In order to facilitate the uniform distribution of the ozone released by the ozone generator 7 throughout the drying cavity, the ozone generator 7 is preferably arranged in the upper part of the assembly cavity, so as to improve the uniformity of the dispersion of ozone in the drying cavity by means of the gravity effect. In order to reduce the number of parts in the drying device 100 and make the structure in the assembly cavity more compact, the ozone generator 7 is preferably arranged between the top wall of the ventilation partition 5 and the top of the fixing frame 9.

[0047] In this embodiment, the drying device 100 preferably further includes a partition plate 8 arranged in the housing 1 and above the second air outlet 12. The partition plate 8 is suitable for carrying the articles to be dried. A plurality of air permeable holes are arranged on the partition plate 8, which can facilitate the hot air to pass through the air permeable holes on the partition plate 8 and penetrate the articles placed on the partition plate 8, so as to take away the moisture in the articles, which helps to improve the drying efficiency of the drying device 100. In order to facilitate the operator to put articles such as clothes or ornaments into the drying cavity, the housing preferably includes an open inner container 1b and an upper cover 1a covering the open container.

[0048] In summary, the drying device 100 of this embodiment can overcome the defect that the air field and temperature field in the drying device 100 in the prior art are uneven. The drying speed of the drying device 100 of this embodiment is greatly improved compared with similar products of the same model, and it can overcome the defect that the air field and temperature field in the drying device 100 in the prior art are uneven.

[0049] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
