DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present utility model.

[0027] 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 the present utility model belongs. The terminology used in the description of the present utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present utility model. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0028] The present utility model provides a disinfection cabinet which adopts the mode of generating high-temperature steam to disinfect tableware, cooking utensils, cups, bottles and other utensils, and the like. Figures 1-2The utility model discloses a sterilizing cabinet, which comprises a cabinet body 10, a steam generator 20, a dispatching pump 30, a water tank 40 and an exhaust and liquid separation chamber 50.

[0029] Referring to Figure 6 The exhaust and liquid separation chamber 50 has a heat absorption channel 51 and a water groove 52. The heat absorption channel 51 comprises an air inlet and an exhaust outlet connected to the sterilizing cavity 11. The air inlet is used for receiving the high-temperature gas mist from the steam generator 20. The inner wall of the heat absorption channel 51 extends in the direction close to the ground and is connected to the inner wall of the water groove 52. Thus, the water groove 52 is formed vertically below the heat absorption channel 51 and is connected to the heat absorption channel 51. The high-temperature gas mist flows in the heat absorption channel 51. Part of the high-temperature gas mist is condensed and liquefied by heat absorption in the heat absorption channel 51. The condensed water generated after liquefaction flows into the water groove 52 by gravity. The steam in the high-temperature gas mist that is not condensed and liquefied enters the sterilizing cavity 11 through the exhaust outlet. Specifically, the steam and droplets with lower temperature in the high-temperature gas mist are cooled and condensed in the heat absorption channel 51. Although the steam with higher temperature in the high-temperature gas mist is also cooled by heat absorption in the heat absorption channel 51, the cooling amplitude is not enough to make this part of the steam condensed and liquefied. The dry steam flowing into the sterilizing cavity 11 can still kill bacteria.

[0030] The dispatching pump 30 can be operated in forward rotation and reverse rotation, and the dispatching pump 30 comprises a first end and a second end. When the dispatching pump 30 is operated in forward rotation, water can enter the dispatching pump 30 from the first end and then flow out of the dispatching pump 30 from the second end. When the dispatching pump 30 is operated in reverse rotation, water can enter the dispatching pump 30 from the second end and then flow out of the dispatching pump 30 from the first end. The water tank 40 comprises an exchange end 41 connected to the first end. The exchange end 41 allows water to pass through and flow out of the water tank 40 and then flow into the dispatching pump 30 from the first end, and also allows water flowing out of the dispatching pump 30 from the first end to pass through and flow into the water tank 40. A supply liquid path is arranged between the second end and the steam generator 20. When the dispatching pump 30 is operated in forward rotation, water entering the dispatching pump 30 from the first end can flow into the supply liquid path from the second end and then flow to the steam generator 20. A supply gas path 84 is arranged between the steam generator 20 and the air inlet, thereby allowing the high-temperature gas mist to flow into the heat-absorbing flow channel 51 along the supply gas path 84. Therefore, the power for water to flow into the steam generator 20 and for the high-temperature gas mist to flow into the heat-absorbing flow channel 51 is provided by the dispatching pump 30 operated in forward rotation. A recovery liquid path is arranged between the water tank 52 and the second end. When the dispatching pump 30 is operated in reverse rotation, the condensed water in the water tank 52 is pumped into the recovery liquid path. The condensed water sequentially passes through the second end, the first end and the exchange end 41 under the driving of the dispatching pump 30 and finally flows back to the water tank 40.

[0031] The disinfection cabinet has the functions of steam high-temperature disinfection, steam drying and dehumidification and condensate water recovery. The functions of steam high-temperature disinfection and steam drying and dehumidification are simultaneously performed and realized based on the forward rotation of the dispatching pump 30. The function of condensate water recovery is realized based on the reverse rotation of the dispatching pump 30. Therefore, the functions of steam high-temperature disinfection and condensate water recovery are not simultaneously performed. When the dispatching pump 30 is operated in forward rotation, the water in the water tank 40 is pumped into the steam generator 20 along the supply liquid path. The water is converted into high-temperature gas mist mixed with liquid drops under the action of the steam generator 20. Then, the high-temperature gas mist is driven and enters the heat-absorbing flow channel 51 along the supply gas path 84 due to the forward rotation of the dispatching pump 30. The steam and liquid drops with lower temperature in the high-temperature gas mist are separated out by being liquefied. The remaining steam with higher temperature is drier than the high-temperature gas mist entering the heat-absorbing flow channel 51 and is more suitable to be discharged into the disinfection cavity 11. When the dispatching pump 30 is operated in reverse rotation, the condensed water in the water tank 52 is pumped into the water tank 40 along the recovery liquid path.

[0032] Referring to Figures 1-3 , Figure 8, the sterilizer further comprises a first three-way pipe 71, a first pipe 81, a second liquid supply pipe 82, a third liquid supply pipe 83, a first control valve 73, a second control valve 74 and a recovery liquid pipe 85. The first three-way pipe 71 comprises a first connecting end, a second connecting end and a third connecting end. The second end is connected to the first connecting end. The liquid supply path is connected to the second connecting end. The recovery liquid path is connected to the third connecting end. Specifically, the two ends of the first pipe 81 are respectively connected to the exchange end 41 of the water tank 40 and the first end of the dispatch pump 30. The two ends of the second liquid supply pipe 82 are respectively directly connected to the second connecting end and the first control valve 73. The two ends of the third liquid supply pipe 83 are respectively directly connected to the first control valve 73 and the steam generator 20. The two ends of the supply gas path 84 are respectively directly connected to the steam generator 20 and the gas inlet. The two ends of the recovery liquid pipe 85 are respectively directly connected to the water tank 52 and the second control valve 74. The second control valve 74 is connected to the third connecting end. The second liquid supply pipe 82, the first control valve 73 and the third liquid supply pipe 83 form a liquid supply path in series with the supply gas path 84. The recovery liquid pipe 85 and the second control valve 74 form a recovery liquid path.

[0033] Referring to Figure 8 When the sterilizer runs the steam high-temperature disinfection function, the dispatch pump 30 rotates forward, the first control valve 73 is opened and the second control valve 74 is closed, the liquid supply path and the supply gas path 84 are unblocked, and the recovery liquid path is blocked. The water in the water tank 40 flows through the exchange end 41, the first pipe 81, the first dispatch pump 30, the first three-way pipe 71, the second liquid supply pipe 82, the first control valve 73, the third liquid supply pipe 83, the steam generator 20 and the supply gas path 84 in turn to enter the heat absorption flow channel 51. When the sterilizer runs the condensate recovery function, the dispatch pump 30 reverses, the first control valve 73 is closed and the second control valve 74 is opened, the liquid supply path is blocked and the recovery liquid path is unblocked. The condensate in the water tank 52 flows through the recovery liquid pipe 85, the second control valve 74, the first three-way pipe 71, the first dispatch pump 30, the first pipe 81 and the exchange end 41 in turn to enter the water tank 40. In actual use, the dispatch pump 30 can alternately rotate forward and reverse, so that the sterilizer alternately performs steam high-temperature disinfection and condensate recovery. It can also continuously rotate forward for a period of time, and then continuously rotate reverse for a period of time, so as to perform steam high-temperature disinfection first and then perform condensate recovery.

[0034] The process of the gas-liquid separation of the high-temperature gas mist by the exhaust mist separating chamber 50 and the principle of the steam drying and dehumidifying function are described in detail below. The exhaust mist separating chamber 50 further comprises a heat exchange wall 54, the inner side of the heat exchange wall 54 is configured to form a cold water cavity 53, and the outer side of the heat exchange wall 54 is configured to form a heat absorption flow channel 51 and a water tank 52. The sterilizing cabinet further comprises an exchange liquid path and a circulating pump 60 arranged between the cold water cavity 53 and the water tank 40. The cold water cavity 53, the exchange liquid path, the circulating pump 60 and the water tank 40 thus form a liquid circulation loop. The cold water cavity 53 can also store water. The above-mentioned liquid circulation loop can exchange the water stored in the cold water cavity 53 and the water tank 40 with each other. In particular, when the sterilizing cabinet operates the steam drying and dehumidifying function, the water tank 40 can supply water with a temperature significantly lower than the high-temperature gas mist (referred to as low-temperature water) to the cold water cavity 53. The heat exchange wall 54 is cooled after obtaining the low-temperature water in the cold water cavity 53, and cools the high-temperature gas mist entering the heat absorption flow channel 51. Therefore, the water in the water tank 40 not only serves as a source of the high-temperature gas mist, but also serves as a heat sink after being obtained by the cold water cavity 53, indirectly cooling and absorbing heat of the high-temperature gas mist by directly reducing the temperature of the heat exchange wall 54.

[0035] The water in the cold water cavity 53 not only reduces the temperature of the heat exchange wall 54, but also slowly increases its own temperature. Therefore, the cooling capacity of the water in the cold water cavity 53 (referred to as heat absorption water) gradually decreases as the steam drying and dehumidifying function continues. In order to ensure that the heat exchange wall 54 can continuously cool the high-temperature gas mist, the heat absorption water in the cold water cavity 53 is returned to the water tank 40 through the above-mentioned liquid circulation loop, and then the water tank 40 provides new low-temperature water for the cold water cavity 53 through the liquid circulation loop. Since the temperature of the heat absorption water obtained by the water tank 40 from the cold water cavity 53 is increased, the heat absorption water requires less heat to be converted into the high-temperature gas mist in the steam generator 20, which helps to reduce the energy consumption of the steam generator 20. In the energy of converting water into high-temperature gas mist in the steam generator 20 each time, a part of the energy comes from the heat absorption of the low-temperature water in the cold water cavity 53 to the earlier high-temperature gas mist.

The first outer plate 551 and the second outer plate 552 are respectively provided with a first through hole 554 and a second through hole 555, the first through hole 554 forms an air inlet to communicate the air supply channel 84 with the first flow channel 511, and the second through hole 555 forms an air outlet to communicate the sterilization cavity 11 with the second flow channel 512, the minimum height of the opening edge of the first through hole 554 from the ground is higher than the height of the back ground side from the ground, the minimum height of the opening edge of the second through hole 555 from the ground is higher than the height of the back ground side from the ground, the depth of the condensed water in the first groove 521 is not higher than the lowest point of the opening of the first through hole 554, and the depth of the condensed water in the second groove 522 is not higher than the lowest point of the opening of the second through hole 555.

[0039] Further, referring to Figure 4 and Figure 5, the distance from the first through hole 554 to the top plate 556 is much greater than the distance from the first through hole 554 to the back side of the bottom plate 553, and the distance from the second through hole 555 to the top plate 556 is also much greater than the distance from the second through hole 555 to the back side of the bottom plate 553, in this way, the length of the first flow channel 511 in the direction of the interval between the top plate 556 and the bottom plate 553 is greater, and the length of the second flow channel 512 in the direction of the interval between the top plate 556 and the bottom plate 553 is greater, the high-temperature gas mist enters the heat-absorbing flow channel 51 from the air inlet closer to the ground, and then enters the sterilization cavity 11 from the air outlet closer to the ground, the initial position of the dry steam entering the sterilization cavity 11 is lower, and then the dry steam can float in the sterilization cavity 11, which helps to eliminate sterilization dead angles and avoid that the bottom area of the sterilization cavity 11 cannot be effectively sterilized and disinfected because it cannot be passed through by dry steam, the high-temperature gas mist flows in the heat-absorbing flow channel 51 for a longer distance, and the steam and liquid droplets with lower temperature can be fully cooled and liquefied, which helps to improve the steam drying and dehumidifying effect.

[0040] Further, referring to Figure 4 , the second through hole 555 is a horizontally extending strip-shaped through hole, in this way, the gas flow beam of the dry steam blown into the sterilization cavity 11 from the air outlet is more flat and fine, the dispersion of the dry steam along the length direction of the second through hole 555 is realized, the blowing range of the dry steam is expanded, and the sterilization dead angles in the sterilization cavity 11 are avoided.

In this way, when the water level in the cold water cavity 53 reaches the overflow end 532, the circulating pump 60 can only pump water into the water tank 40, the water in the cold water cavity 53 can almost fill the cold water cavity 53, the upper limit of the water storage capacity of the cold water cavity 53 is higher, and more low-temperature water can absorb more heat of high-temperature gas mist, so that the heat exchange wall 54 can be kept at a lower temperature for a longer time, thereby avoiding the heat exchange wall 54 from being heated for a long time due to contact with high-temperature gas mist, preventing the heat exchange wall 54 from being weakened in the ability to absorb heat of high-temperature gas mist due to heating, and improving the cooling and heat absorption effect of the heat exchange wall 54 on high-temperature gas mist.

The water feeding pipe 86 and the water returning pipe 87 form the exchange liquid path. Water can flow in a circulating manner through the liquid circulation loop and be exchanged between the cold water cavity 53 and the water tank 40 for multiple times, and a complete exchange process comprises that water flows through the water tank 40, the exchange end 41, the second three-way pipe 72, the circulating pump 60, the water feeding pipe 86, the cold water cavity 53 and the water returning pipe 87 in sequence.

[0044] Referring to Figure 8 , when the disinfection cabinet operates the steam high-temperature disinfection function, the water in the water tank 40 flows through the first pipe 81, the second three-way pipe 72, the dispatching pump 30 and the first three-way pipe 71 in sequence and then enters the supply liquid path; when the disinfection cabinet operates the condensate water recovery function, the water in the water tank 52 flows through the recovery liquid pipe 85, the second control valve 74, the first three-way pipe 71, the dispatching pump 30, the second three-way pipe 72 and the first pipe 81 in sequence and then enters the water tank 40; when the water is exchanged between the cold water cavity 53 and the water tank 40, the water in the water tank 40 flows through the first pipe 81, the second three-way pipe 72, the circulating pump 60, the water feeding pipe 86 and the water injection end 531 in sequence and then enters the cold water cavity 53, and the water in the cold water cavity 53 flows through the overflow end 532, the water returning pipe 87 and the water inlet end 42 in sequence and then enters the water tank 40, and the power for the water to flow from the water tank 40 into the cold water cavity 53 and the water to flow from the cold water cavity 53 into the water tank 40 is provided by the circulating pump 60.

[0045] It is worth mentioning that the dispatch pump 30 and the circulating pump 60 are independently operated and do not affect each other's working state: the dispatch pump 30 and the circulating pump 60 can be operated at the same time or at different time periods; while the circulating pump 60 is running, the dispatch pump 30 can run in forward rotation or reverse rotation.

[0046] The cold water cavity 53 is another water storage area outside the water tank 40, so the volume of the water tank 40 can be reduced compared to the same type of product, and the reduced volume of the water tank 40 is compensated by the cold water cavity 53. Therefore, the disinfection cabinet of the present application can make the water tank 40 more miniaturized and lightened, so as to be more convenient for installation on the cabinet body 10. The water in the cold water cavity 53 is used as a cold source to cool the heat exchange wall 54, and the heat exchange wall 54 further cools the high-temperature gas mist, so that the cooling and liquefaction of the steam and droplets with lower temperature does not need to consume external energy. Using the water in the cold water cavity 53 as a cold source to indirectly heat and cool the high-temperature gas mist can accurately control the cooling amplitude of the high-temperature gas mist, avoid the cooling and liquefaction of the high-temperature gas mist, and ensure that sufficient dry steam enters the disinfection cavity 11.
