DETAILED DESCRIPTION

[0024] Currently, disinfection cabinets on the market often use a combination of high temperature and ozone ultraviolet and other methods to disinfect. However, high-temperature disinfection will cause plastic tableware to melt, and high-temperature tableware can easily cause burns to users, resulting in complaints and other risks. Ozone ultraviolet disinfection technology will leave ozone residue during and after the disinfection process, polluting the air and affecting the quality of the tableware.

[0025] In order to avoid a series of problems caused by the above-mentioned disinfection methods, some manufacturers also use steam for disinfection. However, steam disinfection also has some problems. For example, due to the limited flow range of steam, the temperature field in various parts of the steam sterilizer is uneven and there are problems of sterilization dead corners. In addition, water stains left by steam are easily left on the tableware, thus affecting the user experience.

[0026] See also Figure 1-Figure 4 In order to simultaneously solve the problems of uneven temperature field and easy residual water stains in steam sterilization, the present application provides a steam sterilization cabinet, which includes a cabinet body 100, a gas-liquid separator 200, a transmission assembly 300, a fan 400, a liquid pump 120, a first solenoid valve 160, a second solenoid valve 170, a steam generator 150, a water tank 140, a control assembly (not shown) and an inner tank 130. The cabinet body 100 is provided with an assembly cavity 110, and the inner tank 130, the gas-liquid separator 200, the fan 400, the liquid pump 120, the first solenoid valve 160, the second solenoid valve 170 and the steam generator 150 are all arranged in the assembly cavity 110.

[0027] The water tank 140 is connected to the steam generator 150 through a pipeline, the steam generator 150 is connected to the gas-liquid separator 200 through a pipeline, the gas-liquid separator 200 is respectively connected to the water tank 140 and the inner tank 130 through pipelines, and the control component is electrically connected to the first solenoid valve 160, the second solenoid valve 170, the steam generator 150 and the liquid pump 120 respectively.

[0028] When the steam sterilizer is turned on to the sterilization mode, the control component controls the liquid pump 120 to rotate forward and the first solenoid valve 160 to open. The liquid pump 120 can pump liquid water into the steam generator 150 and form steam in a gas-liquid mixed form (the steam containing liquid water is called steam). Then, the steam is allowed to enter the gas-liquid separator 200 through a pipeline, so that the liquid water and water vapor (also called gaseous water) are separated in the gas-liquid separator 200, and the water vapor enters the inner tank 130.

[0029] In addition, one end of the fan 400 is connected to the gas-liquid separator 200 through the transmission assembly 300, and the other end is arranged toward the inner tank 130. The steam entering the gas-liquid separator 200 can drive the gas-liquid separator 200 to rotate through the transmission assembly 300, so that the fan 400 can blow air toward the inner tank 130, thereby making the water vapor in the inner tank 130 flow.

[0030] When the steam sterilizer is turned on in dewatering mode, the control component controls the liquid pump 120 to reverse and the second solenoid valve 170 to open, and the liquid pump 120 can pump the liquid water in the gas-liquid separator 200 into the water tank 140, so that the water can be recycled and water resources can be saved.

[0031] Furthermore, in one embodiment, the steam sterilizer further includes a three-way pipe (not shown), and the liquid pump 120 is connected to the first solenoid valve 160 and the second solenoid valve 170 respectively through the three-way pipe.

[0032] Further, in one embodiment, if Figure 2 As shown, the steam sterilizer further includes a baffle 180 , which is disposed between the inner liner 130 and the assembly cavity 110 . The baffle 180 forms a pattern where air enters the middle area and air exits around, which is conducive to stirring the water vapor in the inner liner 130 .

[0033] Specifically, Figure 3 and Figure 4As shown, the gas-liquid separator 200 includes a shell 210, an end cover assembly 220, an air outlet pipe 230 and a blade assembly 240. The shell 210 is provided with a separation chamber 211. The end cover assembly 220 is sealed and installed at the opening of the separation chamber 211. One end of the air outlet pipe 230 is rotatably connected to the end cover assembly 220, and the other end extends toward the bottom of the separation chamber 211 (away from the end cover assembly 220). In addition, the end of the air outlet pipe 230 away from the end cover assembly 220 is connected to the fan 400 through the transmission assembly 300.

[0034] The blade assembly 240 is connected to the outer peripheral side of the air outlet pipe 230. When the steam in the steam generator 150 enters the separation chamber 211 through the inlet at the end cover assembly 220, the steam can drive the blade assembly 240 to drive the air outlet pipe 230 to rotate axially around itself (referring to the air outlet pipe 230). The air outlet pipe 230 can drive the fan 400 to rotate through the transmission assembly 300, so that the fan 400 can deliver airflow toward the inner tank 130.

[0035] The outer walls of the blade assembly 240 and the air outlet pipe 230 are arranged to form a separation channel 244, through which liquid water can enter the separation chamber 211 away from the bottom of the end cover assembly 220. The air outlet pipe 230 is provided with an air inlet 231 at the bottom away from the end cover assembly 220, and water vapor can enter the inner tank 130 through the separation channel 244, the air inlet 231 and the air outlet pipe 230 in sequence.

[0036] The present application cleverly utilizes the steam in the disinfection cabinet itself to provide power, drives the air outlet pipe 230 to rotate through the blade assembly 240, and transmits the torque to the fan 400 through the transmission assembly 300, and finally realizes the flow of water vapor in the inner tank 130 through the rotation of the fan 400.

[0037] Obviously, the product of the steam sterilizer of the present application is only water. Therefore, it can be seen that the steam sterilizer of the present application has the advantages of being green, environmentally friendly, safe and reliable, and having no odor.

[0038] Furthermore, the steam sterilizer can not only separate water vapor and liquid water through the separation channel 244 in the gas-liquid separator 200, so that the liquid water is stored in the gas-liquid separator 200, and the water vapor enters the inner tank 130, so as to avoid residual water stains on tableware and other items, so as to improve the user experience. In addition, the fan 400 can be driven to rotate by the rotation of the air outlet pipe 230 in the gas-liquid separator 200, so as to introduce air flow into the inner tank 130, so as to make the high-temperature water vapor in the inner tank 130 flow, thereby accelerating the high-temperature water vapor to cover every corner in the inner tank 130, so as to achieve the sterilization without dead angles of the steam sterilizer, and the temperature of each part of the inner tank 130 can be made more uniform, that is, the uniformity of the temperature field is improved.

[0039] In one embodiment, if Figure 3 and Figure 4 As shown, the blade assembly 240 includes a spiral guide vane 241 and a drive vane 243. The spiral guide vane 241 is arranged between the outer wall of the outlet pipe 230 and the inner wall of the separation chamber 211. The inner side of the spiral guide vane 241 is spirally wound around the axial direction of the outlet pipe 230 and connected to the outer peripheral side of the outlet pipe 230. The outer side of the spiral guide vane 241 and the inner wall of the separation chamber 211 are rotationally sealed. In this way, steam will not leak from the gap between the spiral guide vane 241 and the inner wall of the separation chamber 211, thereby increasing the thrust of the steam on the blade assembly 240.

[0040] The outer wall of the air outlet pipe 230 , the spiral guide plate 241 and the inner wall of the separation chamber 211 are jointly arranged to form a separation channel 244 , which spirally extends from one end of the separation chamber 211 close to the end cover assembly 220 to the other end of the separation chamber 211 away from the end cover assembly 220 .

[0041] The driving plate 243 is fixedly connected to the spiral guide plate 241 or the outer wall of the air outlet pipe 230, and the driving plate 243 protrudes from the inner wall of the separation channel 244 and partially blocks the separation channel 244 along the cross-sectional direction of the separation channel 244, so that the airflow of the steam can push the air outlet pipe 230 to rotate through the driving plate 243 without affecting the steam from passing through the separation channel 244 into the bottom of the separation chamber 211.

[0042] With such arrangement, on the one hand, the driving plate 243 can effectively drive the blade assembly 240 and the exhaust pipe 230 to rotate, and on the other hand, by setting a spirally extended separation channel 244, the flow path of the steam in the separation chamber 211 can be extended, thereby improving the gas-liquid separation effect.

[0043] But not limited to this, in other embodiments, the blade assembly 240 can also be a fan blade structure.

[0044] Further, in one embodiment, if Figure 3 and Figure 4 As shown, the spiral guide plate 241 is provided with a through hole 242 that penetrates the spiral guide plate 241 along the axial direction of the air outlet pipe 230 , and the separation chamber 211 is located at both ends of the spiral guide plate 241 along the axial direction of the air outlet pipe 230 and can be linearly connected through multiple through holes 242 .

[0045] Such an arrangement can balance the steam pressure. When the steam pressure is too high, the through hole 242 can relieve pressure to a certain extent, thereby preventing the blade assembly 240 and the air outlet pipe 230 from being damaged due to excessive pressure.

[0046] In one embodiment, if Figure 2 and Figure 3As shown, the pipeline between the air outlet pipe 230 and the inner liner 130 is defined as the ventilation pipeline 500, and the gas-liquid separator 200 also includes a bearing 260, and the air outlet pipe 230 is rotatably connected to the end cover assembly 220 through the bearing 260, and the ventilation pipeline 500 is fixedly connected to the end cover assembly 220.

[0047] Such an arrangement can prevent the ventilation line 500 from being driven to rotate by the air outlet pipe 230, causing the ventilation line 500 to twist and tangle.

[0048] It should be noted that if Figure 3 and Figure 4 As shown, the end cover assembly 220 includes a support ring 221 and a connecting cover 222, the air outlet pipe 230 is fixedly inserted into the connecting cover 222 and connected to the support ring 221 through the connecting cover 222, the support ring 221 is sealed at the opening of the separation chamber 211, and the air outlet pipe 230 is rotatably connected to the support ring 221 through a bearing 260.

[0049] Further, in one embodiment, if Figure 3 As shown, the gas-liquid separator 200 also includes a rotating sealing sleeve 250, one end of the rotating sealing sleeve 250 is fixedly connected to the outlet pipe 230, and the other end is rotatably sleeved on the outer peripheral side of the ventilation pipe 500, or, one end of the rotating sealing sleeve 250 is fixedly sleeved on the outer peripheral side of the ventilation pipe 500, and the other end is movably inserted into the outlet pipe 230.

[0050] In this way, the sealing performance between the ventilation line 500 and the air outlet pipe 230 can be improved.

[0051] It should be noted that if Figure 3 As shown, in order to further improve the sealing performance, a sealing ring 270 may be provided between the two relatively rotating parts to prevent water vapor leakage.

[0052] Furthermore, in another embodiment, a flared portion (not shown) is provided at one end of the ventilation duct 500 close to the end cover assembly 220, and the ventilation duct 500 is fixedly connected to the end cover assembly 220 via the flared portion, and the flared portion is sleeved on the outer side of the bearing 260 (it may contact the outer peripheral wall of the shaft side, or it may not contact the outer peripheral wall of the bearing 260).

[0053] In this way, the ventilation pipeline 500 and the gas outlet pipe 230 are not in contact with each other, which further reduces the risk of leakage of the gas-liquid separator 200.

[0054] In one embodiment, if Figure 3 and Figure 4As shown, the transmission assembly 300 includes a first transmission rod 310, a first bevel gear 330, a second bevel gear 340 and a second transmission rod 320, the outlet pipe 230, the first transmission rod 310 and the first bevel gear 330 are connected in sequence and coaxially arranged, the fan 400, the second transmission rod 320 and the second bevel gear 340 are connected in sequence and coaxially arranged, and the first bevel gear 330 and the second bevel gear 340 are meshed and arranged at an angle.

[0055] In this way, it is applicable to the situation that the rotation axis of the fan 400 and the rotation axis of the air outlet pipe 230 do not coincide with each other, which is beneficial to the reversal of the output torque of the air outlet pipe 230.

[0056] Preferably, the rotation axis of the fan 400 and the rotation axis of the air outlet pipe 230 are arranged perpendicularly.

[0057] However, it is not limited thereto. In other embodiments, the transmission assembly 300 may also be a belt transmission structure or a worm gear structure, etc., which are not listed here one by one.

[0058] Further, in one embodiment, if Figure 3 and Figure 4 As shown, the shell 210 includes a sleeve section 212 and a liquid storage section 213. The liquid storage section 213 is connected to one end of the sleeve section 212 away from the end cover assembly 220, and an assembly hole 214 is provided at the connection between the sleeve section 212 and the liquid storage section 213. The second transmission rod 320 is movably inserted into the assembly hole 214.

[0059] It should be noted that the sleeve segment 212 and the support ring 221 of the end cover assembly 220 are connected by fasteners such as screws.

[0060] In this way, the split design of the housing 210 facilitates the assembly of the transmission assembly 300 .

[0061] However, the present invention is not limited thereto. In other embodiments, the housing 210 may also be integrally formed.
