Technical Field

[0001] The present invention relates to the technical field of disinfection cabinets, and in particular to a mildew-proof disinfection cabinet. Background Art

[0002] The disinfection cabinet is a small household appliance for drying and disinfecting tableware and kitchen utensils. The tableware and kitchen utensils used by people are made of metal, plastic, wood, and even paper. When disinfecting, the existing disinfection cabinet closes the cabinet door and the first cavity is sealed.

[0003] However, in actual use, people put the washed dishes and kitchen utensils in the pull-out basket without wiping them dry, and then start drying and disinfecting. During the heating process of the first cavity, the water stuck to the dishes and kitchen utensils will evaporate due to the heat, and the evaporated water will turn into mist in the cavity. When the temperature in the cabinet cavity reaches the set value or the drying and disinfection time is reached, the work is stopped. The old products have small exhaust holes and no power discharge device. They rely on air pressure discharge, and the steam discharge is not clean, the temperature in the cabinet cavity drops, and the previously evaporated mist condenses and falls on the dishes and kitchen utensils.

[0046] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0047] like Figures 1 to 7 As shown, a mildew-proof disinfection cabinet in one embodiment of the present invention comprises a housing 10 and a heating module 13 and a ventilation module 12 arranged in the housing 10;

[0048] The shell 10 is provided with a first cavity 11; the ventilation module 12 includes a blowing module 30 and a plurality of exhaust sealing grilles 50; the blowing module 30 is arranged in the first cavity 11; the exhaust sealing grille 50 includes an upper sealing block 51 and a lower sealing block 52; and a plurality of sealing slots 53 are formed between the upper sealing block 51 and the lower sealing block 52; the sealing slots 53 separate the first cavity 11 and the external space; the heating module 13 includes a heating element 21, a first motor and a sliding guide rail 20; the first motor is arranged at the heating element 21; the sliding guide rail 20 is arranged in the first cavity 11; the heating element 21 is slidably connected to the sliding guide rail 20.

[0049] The sub-sealed structure formed by the upper sealing block 51 and the lower sealing block 52 allows the gas in the first cavity 11 to flow out from the sealing slot 53 when the heating module 13 is in operation under the influence of the pressure difference between the inside and outside of the device, while the air cannot flow into the first cavity 11 when the heating module 13 is not in operation, thereby achieving the purpose of preventing bacteria in the air from entering the first cavity 11; the provision of the blowing module 30 is helpful to accelerate the flow of high-temperature gas in the first cavity 11, increase the flow rate of gas flowing out of the first cavity 11 through the exhaust sealing grid 50, and at the same time assist in raising the temperature of the dishes and chopsticks placed in the first cavity 11, so as to achieve the purpose of high-temperature disinfection; the combination of the sliding guide rail 20 and the heating element 21 allows the heating element 21 to be moved to the corresponding position of the corresponding dishes and chopsticks, so as to perform targeted heating, thereby achieving the purpose of more effective sterilization, disinfection and mildew prevention.

[0050] In one embodiment, the heating element 21 includes a support seat 22; the sliding guide rail 20 is in a groove shape, and a plurality of teeth are connected to the inner sides of the groove of the sliding guide rail 20; the support seat 22 is provided with a first gear, the first motor is arranged in the support seat 22, and one end of the power output end of the first motor is axially connected to the first gear, and the first gear is meshed with the teeth, based on which the support seat 22 is connected to the sliding guide rail 20. The first motor drives the support seat 22 to move in the length direction of the sliding guide rail 20, so that the heating element 21 can reach the specific position where the dishes and chopsticks are placed, so as to achieve the purpose of targeted heating.

[0051] In one embodiment, the heating element 21 further includes a plurality of supporting claws 24 and a mounting seat 23; one end of the mounting seat 23 is connected to the supporting seat 22, the other end of the power output end of the first motor is axially connected to the mounting seat 23, and the other end of the mounting seat 23 is hinged to the supporting claw 24; the heating element 21 further includes a heating object 29; the heating object 29 is arranged on the mounting seat 23 based on the supporting claw 24. When the first motor is working, it not only drives the first gear to rotate, but also drives the mounting seat 23 to rotate. Through the rotating mounting seat 23, the heating object 29 also rotates, and further, the radiation angle of the heating object 29 also changes, which is conducive to the effective sterilization and mildew prevention of dishes and chopsticks placed in special positions or special shapes.

[0052] In one embodiment, the support claw 24 includes a first body 25, a reset spring 26, a first clamp block 27 and a second clamp block 28; the first body 25 is arranged on the mounting seat 23, and the first clamp block 27 and the second clamp block 28 are symmetrically arranged at the first body 25; the two ends of the reset spring 26 are respectively connected to the first clamp block 27 and the second clamp block 28. Under the action of the reset spring 26, the first clamp block 27 and the second clamp block 28 always maintain a movement trend of approaching each other. When placing a heating object 29, it is only necessary to break the first clamp block 27 and the second clamp block 28 apart, place the heating object 29 between the first clamp block 27 and the second clamp block 28, and release the hand. At this time, the first clamp block 27 and the second clamp block 28 are close to each other under the action of the reset spring 26, so as to clamp the heating object 29. When the heating object 29 is damaged, the user only needs to pull the heating object 29 out from between the first clamp block 27 and the second clamp block 28, and then replace it with a new heating object 29, which is conducive to the user to quickly replace the heating object 29 and improve the maintenance convenience of the device.

[0053] Furthermore, through the cooperation of the support seat 22, the sliding guide rail 20, the first motor and the mounting seat 23, the functions of mobile heating and rotary heating are realized, and the heating uniformity is greatly improved, making the sterilization, disinfection and mildew-proofing of the dishes and chopsticks more thorough and effective.

[0054] Furthermore, the first clamping block 27 and the second clamping block 28 are specifically made of high temperature resistant insulating rubber.

[0055] Furthermore, the heating object 29 can be a far-infrared quartz heating tube, and the far-infrared quartz heating tube is connected to an external power source via an electric wire so as to be powered on and work. The far-infrared quartz heating tube heats the tableware directly or indirectly by heating the air or generating radiant heat, so that the surface temperature of the tableware reaches a certain high temperature value. The high temperature can denature or coagulate the protein and enzyme of the microorganism, causing the protein structure to change and the function to be lost, and the metabolism is hindered and the microorganism dies, thereby achieving the purpose of disinfection. Moreover, the far-infrared quartz heating tube has a low cost and can be easily purchased in the market, so the convenience of maintenance and replacement is greatly improved.

[0056] In one embodiment, the upper sealing block 51 and the lower sealing block 52 are both configured as rack-shaped structures; the rack-shaped structure is specifically a trapezoidal tooth structure, and a top gap is left at the mating position of the tooth top of the trapezoidal tooth structure.

[0057] Furthermore, the exhaust sealing grid 50 separates the first cavity 11 from the external space; the sealing slot 53 is a gap with a width of less than 0.02 mm, and the sealing slot 53 can also be a gap formed by the upper sealing block 51 and the lower sealing block 52 partially pressing against each other. Based on this, the upper sealing block 51 and the lower sealing block 52 form a sub-sealed state, and the sub-sealed state is: the exhaust sealing grid 50 with a certain sealing ability can pass through the air with a certain pressure but cannot penetrate the place of normal pressure gas, and this state is called a sub-sealed state. Based on this, the gas in the first cavity 11 expands due to heat and the air pressure increases, so the gas in the first cavity 11 can flow out to the outside from the gap between the upper sealing block 51 and the lower sealing block 52, while the outside air cannot flow to the first cavity 11 through the gap between the upper sealing block 51 and the lower sealing block 52.

[0058] In one embodiment, the sealing slots 53 are distributed in a linear array. By setting the sealing slots 53 to be distributed in a linear array, a gas discharge situation is formed and external gas can be strictly prevented from entering. When the heating element 21 heats the first cavity 11, the gas in the first cavity 11 is expanded, and the gas pressure rises to a certain pressure. The gas will leak out from the sealing slots 53 in the sub-sealed position. In this way, it can prevent excessive pressure and effectively retain heat in the first cavity 11 to heat the dishes.

[0059] In one embodiment, the blowing module 30 includes a shell 31, a second motor 32, a blade assembly 33, a cover body 36, a magnetic resistance assembly 38 and an air guide cover 41; the second motor 32, the blade assembly 33, the cover body 36, the magnetic resistance assembly 38 and the air guide cover 41 are arranged in the shell 31 in sequence; the power output end of the second motor 32 is axially connected to the blade assembly 33; the blade assembly 33 is axially connected to the air guide cover 41.

[0060] Furthermore, the blade assembly 33 includes an active blade 34 and a driven blade 35, the housing 31 and the cover 36 are combined to form a second cavity, the second motor 32, the active blade 34 and the driven blade 35 are arranged in sequence from top to bottom, and the driven blade 35 is close to the cover 36, the air guide 41 is arranged at the cover plate, and the magnetic resistance assembly 38 is arranged at the air guide 41 and the cover plate. When the second motor 32 is in operation, the second motor 32 drives the active blade 34 to rotate to generate wind force, and when the active blade 34 is running to generate wind force, the driven blade 35 is driven by the wind force to rotate relative to the central axis of the driven blade 35, and drives the air guide hood to rotate.

[0061] Furthermore, the cover body 36 includes a first flow guide structure 37, and the wind guide cover 41 includes a second flow guide structure 42. The first flow guide structure 37 and the second flow guide structure 42 may be shaped but not limited to an annular structure, a sheet structure, a mesh structure, a hollow structure or a rectangular structure, so as to increase the air inlet and outlet areas, or to withstand the wind force generated by the active blades 34, thereby driving the wind guide cover 41 to rotate. The principles of fluid mechanics can be used to provide the air volume required for the operation of the active blades 34, or to partially recover the air volume generated after the operation of the driven blades 35 and the active blades 34 for recirculation, so as to improve the overall efficiency of the gas convection cycle.

[0062] In one embodiment, the magnetic resistance component 38 includes a first magnetic element 39 and a second magnetic element 40; the first magnetic element 39 is arranged on the cover 36 and the wind guide cover 41, and the second magnetic element 40 is arranged on the cover 36 or the wind guide cover 41. Since the magnetic forces of the first magnetic element 39 and the second magnetic element 40 are different, when the wind guide cover 41 is working, the first magnetic element 39 and the second magnetic element 40 cooperate with each other to generate magnetic eddy currents through magnetic force changes and induction, thereby generating magnetic torque on the wind guide cover 41 to slow down or reduce the rotation speed of the wind guide cover 41. Based on this, the magnetic resistance component 38 produces a better damping effect, and the rotation speed of the wind guide cover 41 is adjusted by the magnetic resistance component 38 to optimize the wind guiding effect, thereby achieving the purpose of improving the air circulation efficiency in the first cavity 11 and achieving sufficient heat diffusion.

[0063] In one embodiment, the first magnetic element 39 is a permanent magnet; and / or the second magnetic element 40 is a permanent magnet.

[0064] In one embodiment, the first magnetic element 39 is a magnetic conductor; and / or the second magnetic element 40 is a magnetic conductor.

[0065] In summary: the sub-sealed structure formed by the upper sealing block 51 and the lower sealing block 52 enables the gas in the first cavity 11 to flow out from the sealing slot 53 when the heating module 13 is operating under the influence of the pressure difference between the inside and outside of the device, and when the heating module 13 is not operating, the air cannot flow into the first cavity 11, thereby preventing the bacteria in the air from entering the first cavity 11, so as to achieve the purpose of mildew prevention; by setting the blowing module 30, it is helpful to accelerate the flow of high-temperature gas in the first cavity 11, increase the flow rate of gas flowing out of the first cavity 11 through the exhaust sealing grid 50, and at the same time assist in raising the temperature of the dishes and chopsticks placed in the first cavity 11, so as to achieve the purpose of high-temperature disinfection; through the cooperation of the support seat 22, the sliding guide rail 20, the first motor and the mounting seat 23, the functions of mobile heating and rotary heating are realized, the heating uniformity is greatly improved, and the sterilization, disinfection and mildew prevention of the dishes and chopsticks are more thorough and effective.

[0066] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0067] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
