Description

Technical Field

[0001] The present invention relates to the technical field of kitchen equipment, in particular to a steam sterilizing cabinet. Background Art

[0002] A disinfection cabinet is a device that uses ultraviolet light, far infrared light, high-temperature steam, ozone, and other methods to dry, sterilize, and dehumidify items such as tableware, cutlery, towels, clothing, beauty and hairdressing tools, and medical equipment. Steam disinfection uses high-temperature steam to eliminate bacteria and microorganisms. Pure steam has strong penetrating properties, and proteins and protoplasmic colloids readily denature and solidify under hot and humid conditions. Steam enters cells and condenses into water, releasing latent heat, raising the temperature and enhancing its bactericidal power.

[0003] For example, the Chinese invention patent "A Steam Sterilizer" with patent application number CN202122327449.7 (authorization announcement number CN216294742U) discloses a steam sterilizer, comprising an outer shell, an inner liner arranged in the outer shell, and a water inlet box, a water pump, a steam generator, and a steam nozzle arranged between the outer shell and the inner liner. The water inlet end of the water pump is connected to the inner cavity of the water inlet box, the water inlet end of the steam generator is connected to the water outlet end of the water pump, and the first steam outlet end and the second steam outlet end of the steam generator are respectively connected to the steam inlet of the inner liner and the steam inlet end of the steam nozzle. The steam sterilizer has both internal steam sterilization function and external steam cleaning function. However, the air mobility inside the steam sterilizer is poor, resulting in uneven disinfection and low disinfection efficiency. Summary of the Invention

[0043] A sealing ring 534 is provided on the outer wall of the cleaning arm 53. The cleaning arm 53 is lifted by the movable part 54 and has a first height and a second height. When the cleaning arm 53 is at the first height, the sealing ring 534 covers the first annular hole 571 of the connecting shaft 57; when the cleaning arm 53 is at the second height, a ventilation gap is left between the sealing ring 534 and the first annular hole 571 of the connecting shaft 57.

[0044] In this embodiment, a movable member 54 engages with the inner side of the washing arm 53. A movable flow channel 5a is formed within the movable member 54 to lift and lower the washing arm 53. A washing flow channel 5b is formed between the outer wall of the movable member 54 and the inner wall of the rotating shaft 52, communicating with the washing water inlet 531 of the washing arm 53.

The rotary joint 55 has a first water inlet 551 communicating with the movable flow channel 5a and a second water inlet 552 communicating with the washing flow channel 5b.

[0045] In order to input water into the moving flow channel 5a and the cleaning flow channel 5b, the water inlet end of the water pump 7 is connected to the water inlet tank 6, and the water outlet end of the water pump 7 is divided into two paths leading to the rotary joint 55. One path is provided with a first solenoid valve 8 and leads to the first water inlet 551, and the other path is provided with a second solenoid valve 9 and leads to the second water inlet 552.

[0046] like Figure 7-8 As shown, in order to collect cleaned wastewater, a wastewater outlet 21 is provided at the bottom of the inner tank 2, and a collection assembly 10 for collecting cleaned wastewater is provided below the wastewater outlet 21. The collection assembly 10 includes a bracket 101, a collector 102, a switching valve 103, and a wastewater tank 104. The collector 102 is used to collect wastewater and has a wastewater inlet and a wastewater outlet. The wastewater inlet is directly opposite the wastewater outlet 21 at the bottom of the inner tank 2. The switching valve 103 is mounted on the bracket 101 and has a first switching state and a second switching state. When in the first switching state, the wastewater inlet of the collector 102 is connected to the wastewater outlet; when in the second switching state, the connection between the wastewater inlet of the collector 102 and the wastewater outlet is blocked. The wastewater tank 104 has a first wastewater inlet, which is located below the wastewater outlet of the collector 102.

[0047] In this embodiment, the switching valve 103 includes a second motor 1031 and a valve disc 1032 disposed within the collector 102. The valve disc 1032 has a rotating shaft connected to the output end of the second motor 1031. The valve disc 1032 is switched and rotated between a first switching state and a second switching state via the rotating shaft. The wastewater tank 104 has a second wastewater inlet. A third solenoid valve 11 is provided at the first water inlet 551 of the rotary joint 55 and is connected to the second wastewater inlet to output water from the moving flow channel 5a, thereby moving the cleaning arm 53 downward. To facilitate wastewater collection, a silicone strip 58 is provided below the cleaning arm 53. When the movable member 54 moves the cleaning arm 53 downward, the cleaning arm 53 is pressed against the bottom of the inner liner 2 and the heating base 4 via the silicone strip 58. When the cleaning arm 53 rotates, the silicone strip stirs the water flowing on the bottom of the inner liner 2 and the heating base 4, causing the water to flow toward the wastewater outlet 21.

[0048] The working principle of this embodiment is as follows:

[0049] Disinfection mode: First, turn on the water pump 7 and the first solenoid valve 8, and the water will lift the cleaning arm 53 through the moving flow channel 5a, and by controlling the power-on time of the first solenoid valve 8, the cleaning mechanism 5 is controlled to be in the water inlet / rotation mode, that is, the cleaning arm 53 is at the first height, and the sealing ring 534 on the cleaning arm 53 will cover the first annular hole 571 on the connecting shaft 57; then turn on the water pump 7, the second solenoid valve 9 and the first motor 51, and spray water evenly on the bottom of the inner tank 2 and the heating base 4, and then turn on the heating base 4 to convert the water on the heating base 4 and in the inner tank 2 into water vapor for disinfection; then turn on the first motor 51, and ensure that the first motor 51 rotates at a high speed. Due to the presence of the second fan blade 59, the air inlet in the middle of the baffle 12 is formed in the cabinet. The effect of air outlet all around stirs the steam in the cabinet, making the temperature field in the cabinet more uniform; after the disinfection is completed, the power-on time of the first solenoid valve 8 is controlled again to control the cleaning component to be in the air intake mode, that is, the cleaning arm 53 is at the second height, and a ventilation gap is left between the sealing ring 534 on the cleaning arm 53 and the first annular hole 571 on the connecting shaft 57, that is, the hole is completely exposed, and then the first motor 51 is turned on to rotate at high speed. When the first fan blade 510 rotates and negative pressure is formed in the middle area, an air inlet 5c can be formed between the first annular hole 571 on the connecting shaft 57 and the second annular hole 533 of the cleaning arm 53, and air is taken in from the activated carbon net 511, enters the cabinet through the air inlet 5c, and the hot and humid air in the cabinet is discharged out of the cabinet through the exhaust valve 512;

[0050] In-cabinet cleaning mode: first, turn on the water pump 7, the second solenoid valve 9, and the first motor 51, and by controlling the power-on time of the first solenoid valve 8, control the cleaning component to be in water inlet / rotation mode, and water is sprayed from the cleaning arm 53, so that the entire heating chassis 4 is evenly covered with water, thereby improving the cleaning rate; open the third solenoid valve 11 to discharge the water in the top flow component 54. Due to the weight of the cleaning arm 53 itself, the silicone strip 58 is pressed on the bottom plate of the inner tank 2 and the heating chassis 4. The cleaning arm 53 rotates under the drive of the first motor 51, which can deeply clean the bottom of the inner tank 2 and the heating chassis 4; during the cleaning process, the cleaned wastewater slowly passes through the wastewater outlet 21 on the bottom plate of the inner tank 2 under the action of the silicone strip 58 and enters the collection component 10, and then turns on the second motor 1031 to rotate the valve plate 1032, so that the cleaned wastewater enters the wastewater tank 104, eliminating the process of manual wastewater treatment.
