Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom appliance technology, and in particular to a disinfection cabinet. Background Technology

[0002] Disinfection cabinets offer various disinfection modes, including high-temperature steam disinfection, ultraviolet irradiation disinfection, and ozone disinfection. Taking high-temperature steam disinfection and ozone disinfection as examples, traditional disinfection cabinets face the problem of disinfection dead zones within the disinfection chamber, where disinfectant gases struggle to diffuse and reach these areas, resulting in unsatisfactory disinfection effects. The main reason for these dead zones is poor diffusion of the disinfectant gases within the chamber. Some existing disinfection cabinets incorporate agitation diffusion functions, such as adding a turbulent fan to agitate the disinfectant gases and improve their uniformity within the chamber. However, this increases the cost of the disinfection cabinet, and the turbulent fan is prone to malfunction in the high-temperature, high-humidity environment of the disinfection chamber. Utility Model Content

[0003] In view of this, the present invention provides a disinfection cabinet that can achieve uniform diffusion of disinfecting gas in the disinfection chamber while taking into account both cost and reliability of gas diffusion function.

[0004] The disinfection cabinet of this utility model includes a cabinet body, a conveying component and a diffuser. The cabinet body has a disinfection chamber, the conveying component has an exhaust port that communicates with the disinfection chamber, and the diffuser is movably disposed on the cabinet body and / or the conveying component. The diffuser includes a windward part that extends to the air outlet side of the exhaust port, and also includes a wind-dispersing part that is movably connected to the windward part.

[0005] This invention utilizes the thrust of disinfectant gas blown from the exhaust port onto the windward section, thereby giving the diffuser kinetic energy and causing the air-dispersing section to agitate the disinfectant gas. Under the agitation of the air-dispersing section, the disinfectant gas changes its flow direction and gradually diffuses into the disinfection chamber. No additional drive component is needed to drive the diffuser. The power for the diffusion of the disinfectant gas comes from the kinetic energy of the disinfectant gas leaving the exhaust port. Therefore, as long as disinfectant gas is generated, this invention's disinfection cabinet can spontaneously achieve the diffusion and uniform distribution of the disinfectant gas in the disinfection chamber to better eliminate disinfection dead zones. Since no drive component is needed to provide energy for the diffuser to agitate the disinfectant gas, the cost of the disinfection cabinet is reduced, the problem of easy failure of the drive component is eliminated, and the reliability of the diffuser in agitating the disinfectant gas is improved.

[0006] In some embodiments, the windward portion covers the exhaust port on the air outlet side and is fixed relative to the wind-disrupting portion.

[0007] In some embodiments, the conveyor is provided with a rotatable rotating member, the diffuser is fixed to the rotating member, and the windward part rotates with the diffuser to cover the exhaust port multiple times.

[0008] In some embodiments, the rotating component is used to rotate around a preset turbulence center, and the maximum radius of the diffuser rotating around the preset turbulence center is not less than the minimum distance from the exhaust port to the preset turbulence center.

[0009] In some embodiments, the diffuser includes a plurality of fan blades arranged around a preset turbulence center on the rotating member, with the side of the fan blades near the conveyor and the other side of the fan blades facing away from the conveyor forming a windward section and a turbulence section, respectively.

[0010] In some implementations, any two adjacent fan blades are spaced apart to form multiple air gaps, which surround a preset turbulence center and are arranged alternately with the fan blades.

[0011] In some embodiments, in the two fan blades that form any air gap, one of the blades is inclined in the same direction relative to the preset turbulence center and the exhaust port on the side closer to the conveyor and the other is inclined on the side away from the conveyor; when both fan blades are rotated to obliquely cover the exhaust port, the air gap between them connects to the exhaust port.

[0012] In some embodiments, the conveying member includes an air outlet cover that has an exhaust port and is perpendicular to a preset turbulence center.

[0013] In some embodiments, the conveyor covers the opening of the disinfection chamber, and the diffuser is movably disposed inside the disinfection chamber.

[0014] In some implementations, the distance from the diffuser to the bottom wall of the sterilization chamber is less than the distance from the diffuser to the top wall of the sterilization chamber. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] This invention provides a disinfection cabinet that disinfects tableware, cooking utensils, cups, bottles, and other utensils by generating disinfecting gas. The disinfecting gas can be high-temperature steam, ozone, or a mixture of high-temperature steam and ozone.

[0023] See Figure 1 The disinfection cabinet includes a cabinet body 10, a disinfection gas generator (not labeled in the figure), a conveying component 20, and a diffuser 30. The cabinet body 10 has a disinfection chamber 11, which serves as a place to store the utensils to be disinfected and to contain the disinfection gas. The disinfection gas generator includes a high-temperature steam generator and / or an ozone generator, and can also generate other disinfection gases. The conveying component 20 is connected to the disinfection gas generator and is used to deliver the disinfection gas to the disinfection chamber 11. The diffuser 30 is used to agitate the disinfection gas to diffuse it within the disinfection chamber 11, ultimately achieving a uniform distribution of the disinfection gas within the disinfection chamber 11.

[0024] See Figure 2 See also Figures 3-4 The conveyor 20 has an exhaust port 21 that communicates with the disinfection chamber 11. The disinfection gas is blown out of the exhaust port 21 and leaves the conveyor 20, and then flows into the disinfection chamber 11. The diffuser 30 is movably disposed on the cabinet 10 and / or the conveyor 20. The diffuser 30 includes a windward part 301 and a wind-disrupting part 302. The windward part 301 extends at least to the air outlet side of the exhaust port 21, and the wind-disrupting part 302 is movably connected to the windward part 301.

[0025] Specifically, a gas flow channel leading to the disinfection gas generator is formed within the conveying member 20. The exhaust port 21 serves as the end outlet of this gas flow channel, with the air outlet side being the side of the exhaust port 21 furthest from the gas flow channel and closer to the disinfection chamber 11. After the disinfection gas is blown out from the exhaust port 21, it first applies a thrust to the windward portion 301 located on the air outlet side. As a result, the diffuser 30 is driven by the disinfection gas and gains kinetic energy. Part of the kinetic energy of the disinfection gas is converted into the kinetic energy of the diffuser 30. Then, the turbulence portion 302 moves along with the windward portion 301 and begins to turbulent the disinfection gas. Under the turbulence of the turbulence portion, the flow direction of the disinfection gas changes, and the flow velocity of the disinfection gas tends to be disordered and constantly changing. Finally, the disinfection gas gradually diffuses into the disinfection chamber 11 until the disinfection gas is evenly distributed within the disinfection chamber 11.

[0026] When existing similar products are in use, the disinfectant gas blown out from the exhaust port 21 has a high flow rate, and the kinetic energy of the disinfectant gas is not efficiently utilized. The disinfection cabinet of this utility model transfers part of the kinetic energy of the disinfectant gas to the diffuser 30. After the disinfectant gas acts on the windward part 301, its kinetic energy is reduced. The reduced kinetic energy is used by the diffuser 30 to disturb the disinfectant gas.

[0027] Therefore, the disinfection cabinet of this utility model does not need to be equipped with a driving component to drive the diffuser 30. The power to promote the diffusion of disinfection gas comes from the kinetic energy of the disinfection gas when it leaves the exhaust port 21. After the disinfection gas acts on the windward part 301, the flow rate decreases. As long as disinfection gas is generated and flows out of the exhaust port 21, the disinfection cabinet can spontaneously achieve the diffusion and uniform distribution of disinfection gas in the disinfection chamber 11, thereby better eliminating disinfection dead corners that are difficult for disinfection gas to reach. Since no driving component is required, the cost of the disinfection cabinet is reduced. The problem of the driving component being prone to failure in the high temperature and high humidity disinfection chamber 11 is no longer present. Therefore, the reliability of disturbing the disinfection gas is improved compared with existing similar products.

[0028] In some embodiments, the diffuser 30 has a hollow plate-like structure and includes an air outlet cover 22 with an exhaust port 21. The disinfection chamber 11 has an opening, which is covered by the air outlet cover 22. One side of the air outlet cover 22 is a gas flow channel, and the other side faces the disinfection chamber 11. The diffuser 30 is movably disposed within the disinfection chamber 11. The windward portion 301 covers a portion of the exhaust port 21 on the air outlet side. The windward portion 301 and the wind-disrupting portion 302 are fixedly disposed relative to each other. The disinfection gas blown out from the covered portion of the exhaust port 21 exerts a thrust on the windward portion 301, thereby driving the windward portion 301 and the wind-disrupting portion 302 to move synchronously. A portion of the disinfection gas disturbed by the wind-disrupting portion 302 flows along the air outlet cover 22 through the wall adhesion effect and is then pushed and diffused by the subsequent disinfection gas.

[0029] Optionally, the diffuser 30 extends vertically, and the exhaust cover 22 is a flat plate perpendicular to the horizontal plane. The plane where the exhaust port 21 opens is the side of the exhaust cover 22 facing the disinfection chamber 11. The overall structure of the disinfection cabinet is more compact, and the distance from the diffuser 30 to the bottom wall of the disinfection chamber 11 is much smaller than the distance from the diffuser 30 to the top wall of the disinfection chamber 11. The distance from the bottom wall of the disinfection chamber 11 to the ground is smaller than the distance from the top wall of the disinfection chamber 11 to the ground. When the disinfection gas is high-temperature steam, the high-temperature steam can automatically rise in the disinfection chamber 11 to move away from the bottom wall and closer to the top wall of the disinfection chamber.

[0030] See Figure 2 and Figure 4 In some embodiments, the disinfection cabinet further includes a rotating member 40 rotatably disposed on the conveying member 20. The rotating member 40 is capable of rotating relative to the conveying member 20 around a preset turbulence center, and the diffuser 30 is fixedly connected to the rotating member 40. When the disinfecting gas applies a thrust to the air intake 301, the diffuser 30 and the rotating member 40 rotate together around the preset turbulence center relative to the conveying member 20. The air intake 301 rotates with the diffuser 30, thereby repeatedly covering the exhaust port 21, and the turbulence part 302 rotates with the diffuser 30, thereby repeatedly turbulenting the disinfecting gas.

[0031] The disinfecting gas pushes the windward section 301, causing the diffuser 30 to gain momentum to rotate around a preset turbulence center. The rotational momentum of the diffuser 30 allows it to return to the position where it was previously pushed by the disinfecting gas with each rotation. Then the windward section 301 is pushed by the disinfecting gas again. This process is repeated multiple times, so the diffuser 30 can continuously disturb the disinfecting gas. As long as the disinfecting gas is generated and blown out of the exhaust port 21, the disturbance and diffusion of the disinfecting gas by the diffuser 30 will not stop.

[0032] Optionally, the rotating component 40 includes a rotating shaft rotatably inserted into the air outlet cover 22. The axis of the rotating shaft forms a preset turbulence center. To ensure that the diffuser 30 can extend to the air outlet side of the exhaust port 21 to cover the exhaust port 21 and thus be pushed by the disinfecting gas during rotation around the preset turbulence center, the maximum radius of the diffuser 30 when rotating around the preset turbulence center is not less than the minimum distance from the exhaust port 21 to the preset turbulence center. Figure 2 and Figure 4 The diffuser 30 includes multiple fan blades 31 arranged around a preset turbulence center on the outer periphery of the rotating shaft. The surface of each fan blade 31 near the air outlet cover 22 forms a front section 301, and the surface of each fan blade 31 opposite the air outlet cover 22 forms a turbulence section 302. The maximum radius of rotation of the diffuser 30 around the preset turbulence center is the distance from the end of the fan blade 31 furthest from the rotating shaft to the axis of rotation. The fan blades 31 are lightweight and thin, easily propelled by the disinfecting gas. The disinfecting gas pushes the front section 301, giving the rotating shaft torque; the torque radius is the distance from the exhaust port 21 to the axis of rotation.

[0033] like Figures 3-4 As shown, in some embodiments, the number of fan blades 31 is at least three. Any two adjacent fan blades 31 are spaced apart, forming an air passage gap 32 between adjacent fan blades 31. The multiple air passage gaps 32 are arranged around a preset turbulence center, and the multiple air passage gaps 32 and the multiple fan blades 31 are arranged alternately along the circumference of the preset turbulence center. With this arrangement, after the disinfecting gas pushes the windward part 301, it can flow along the air passage gap 32 from the end of the diffuser 30 near the air outlet cover 22 to the other end of the diffuser 30 opposite to the air outlet cover 22.

[0034] Specifically, if you observe the conveyor 20 and the diffuser 30 directly facing the air outlet cover 22, when the disinfectant gas drives the diffuser 30 to rotate, the exhaust port 21, which was originally covered by the windward part 301, is connected to the air gap 32 as the fan blade 31 leaves. Then the disinfectant gas blown out through the exhaust port 21 can directly enter the air gap 32. Therefore, the exhaust port 21 is not always covered by the windward part 301, but switches between two states: being covered by the windward part 301 and being connected to the air gap 32.

[0035] See Figures 3-4 The direction of the flow velocity of the disinfectant gas just blown out of the exhaust port 21 is basically the same as the direction of extension of the axis of rotation. The fan blades 31 are thin sheets of uniform thickness. For two adjacent fan blades 31 that form any air gap 32, the side of one fan blade 31 that is close to the conveyor 20 and forms the windward part 301 and the side of the other fan blade 31 that is opposite to the conveyor 20 and forms the turbulent part 302 are inclined relative to the preset turbulence center and the air outlet cover plate 22 in approximately the same direction. When any two adjacent fan blades 31 are rotated to cover the exhaust port 21, these two fan blades 31 and the air gap 32 between them are inclined relative to the air outlet cover plate 22 in approximately the same direction, and the air gap 32 is inclined to connect the exhaust port 21. When the disinfecting gas contacts the air intake 301, the thrust exerted by the disinfecting gas on the fan blades 31 includes a vector perpendicular to the axis of rotation. This vector is used to push the fan blades 31 and the axis of rotation to rotate around a preset turbulence center. The torque of the axis of rotation is the distance from the exhaust port 21 to the axis of rotation. While the disinfecting gas pushes the air intake 301, it also flows along the air gap 32 under the guidance of the air intake 301. At this time, the turbulence section 302 acts on the disinfecting gas flowing through the air gap 32 as the fan blades 31 rotate around the preset turbulence center. The force exerted by the turbulence section 302 on the disinfecting gas includes a vector parallel to the axis of rotation and a vector perpendicular to the axis of rotation. The vector parallel to the axis of rotation causes the disinfecting gas to move away from the conveyor 20 and enter the depth of the disinfection chamber 11. The vector perpendicular to the axis of rotation promotes the diffusion of the disinfecting gas. Compared with the disinfecting gas just blown out from the exhaust port 21, the disinfecting gas flowing along the air gap 32 changes the direction of flow velocity and has a larger blowing range.

[0036] Because the diffuser 30 helps diffuse the disinfecting gas, the opening size of the exhaust port 21 can be reduced. A smaller exhaust port 21 can increase the pressure inside the gas flow channel, thereby increasing the initial velocity of the disinfecting gas when it is blown out of the exhaust port 21. The thrust of the exhaust port 21 on the windward part 301 increases accordingly, and the diffuser 30 can therefore be more easily driven by the disinfecting gas. Figures 3-4 As shown, the exhaust port 21 is a horizontally extending strip-shaped opening perpendicular to the preset turbulence center. The vertical dimension of this strip-shaped opening is much smaller than the maximum radius of the diffuser 30 rotating around the preset turbulence center.

[0037] Optionally, the air outlet cover 22 is perpendicular to the preset turbulence center, forming a horizontally extending axis of rotation of the preset turbulence center, and a gap is formed between the diffuser 30 and the air outlet cover 22. With this configuration, the diffuser 30 will not scrape or interfere with the air outlet cover 22 when it rotates around the preset turbulence center.

[0038] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
