Description

Technical Field

[0001] The utility model relates to the field of sterilizers, in particular to a rapid drainage device for a sterilizer. Background Art

[0002] At present, when the sterilizer is in use, the sterilized object needs to be placed in the cavity. The water inside the cavity is treated with high temperature and high pressure to form high temperature and high pressure steam to sterilize the sterilized object. The dirt carried on the surface of the sterilized object will also fall into the tank body to form sewage. The existing sewage discharge from the tank body is controlled by a water pump. However, the water pump will directly contact the sewage during operation, which is prone to blockage and corrosion, and is not conducive to long-term use. In addition, when there is pressure in the sterilization cavity during the sterilization process, the water vapor can be discharged with the help of this pressure. However, since the discharged water vapor is at high temperature and high pressure, it poses a safety hazard and cannot be directly connected to the sewer. In order to avoid the above situation, when discharging during low temperature standby, the user needs to manually open the stop valve to discharge, and the dirty water in the sterilization cavity cannot be automatically and promptly discharged.

[0018] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0019] Please refer to Figure 1 A sterilizer rapid drainage device includes a gas output device 1, a tank body 3, a first solenoid valve 2 and a second solenoid valve 4. The gas output device 1 is connected to the first solenoid valve 2, and the first solenoid valve 2 is connected to the tank body 3; the tank body 3 is connected to the second solenoid valve 4, and the second solenoid valve 4 is connected to the drainage joint assembly 5; the gas output device 1, the first solenoid valve 2 and the second solenoid valve 4 are electrically connected.

[0020] From the above description, it can be seen that the beneficial effect of the present invention is that: when the sewage in the tank body 3 of the sterilizer is discharged, under the control of the controller, the first solenoid valve 2 and the second solenoid valve 4 are opened and a certain pressure of gas is pumped into the tank body 3 through the gas output device 1, and the sewage inside the tank body 3 is squeezed out by the gas and finally discharged by the drainage joint assembly 5; the drainage design of the gas output device 1 avoids the long-term erosion of the traditional water pump by sewage during use, causing blockage or failure; through the control of the first solenoid valve 2 and the second solenoid valve 4, the discharge can be timed, and the discharge is controlled by the system under low temperature conditions, so that the pipeline and corresponding components will not be damaged due to overheating of the discharged sewage and steam.

[0021] Furthermore, a pressure-resistant and high-temperature-resistant pipe is connected between the first solenoid valve 2 and the tank body 3 .

[0022] As can be seen from the above description, high-temperature and high-pressure steam will be generated inside the tank body 3 during sterilization in the sterilizer. The use of pressure-resistant and high-temperature resistant pipes for connection can prevent the high-temperature and high-pressure steam from damaging the pipes.

[0023] Furthermore, a pressure-resistant and high-temperature-resistant pipe is connected between the second solenoid valve 4 and the tank body 3 .

[0024] As can be seen from the above description, high-temperature and high-pressure steam will be generated inside the tank body 3 during sterilization in the sterilizer. Using pressure-resistant and high-temperature resistant pipes to connect them can prevent the high-temperature and high-pressure steam from damaging the pipes.

[0025] Furthermore, the drainage joint assembly 5 is connected to the sewer.

[0026] It can be seen from the above description that sewage is directly discharged into the sewer through the drainage joint assembly 5 .

[0027] Furthermore, a drainage container 6 is included, and the drainage joint assembly 5 is connected to the drainage container 6.

[0028] From the above description, it can be seen that for indoor use scenarios, the sterilizer cannot discharge sewage directly into the sewer, so the discharged sewage can be temporarily collected through the drainage container 6, and then the drainage container 6 can be transferred and discharged later.

[0029] Furthermore, a third connecting pipe is connected between the drainage joint assembly 5 and the drainage container 6 , and the third connecting pipe is connected to the upper end of the drainage container 6 .

[0030] As can be seen from the above description, by connecting the third connecting pipe to the upper end of the drainage container 6, it is avoided that when the connecting pipe penetrates deep into the drainage container 6, the gas pumping of the gas output device 1 causes the discharged sewage to carry air, resulting in the sewage in the drainage container 6 bubbling and rolling due to the injection of air, and the sewage splashing out of the drainage container 6.

[0031] Furthermore, there are multiple gas output devices 1 , and each of the gas output devices 1 is connected to a first solenoid valve 2 and a tank body 3 in sequence.

[0032] It can be seen from the above description that the discharge efficiency of sewage inside the tank body 3 can be improved through the design of multiple gas output devices 1 and the first solenoid valve 2.

[0033] Furthermore, the connection parts between the plurality of first solenoid valves 2 and the tank body 3 are evenly spaced along the circumference of the tank body 3 .

[0034] As can be seen from the above description, the uniform arrangement of the connection parts between the multiple first solenoid valves 2 and the tank body 3 ensures that the gas inside the tank body 3 is pumped evenly without mutual interference or backflow affecting the gas output of a certain connection part.

[0035] Furthermore, it also includes a first manual ball valve, which is arranged between the gas output device 1 and the tank body 3 and is connected to the first solenoid valve 2.

[0036] As can be seen from the above description, by setting the first manual ball valve, when the first solenoid valve 2 fails, the first manual ball valve can be manually closed to avoid leakage of high-temperature and high-pressure steam inside the tank body 3.

[0037] Furthermore, a second manual ball valve is included, which is arranged between the drain joint assembly 5 and the tank body 3 and is connected to the second solenoid valve 4.

[0038] It can be seen from the above description that, by providing the second manual ball valve, when the second solenoid valve 4 fails, the second manual ball valve can be manually closed to avoid sewage leakage.

[0039] Example 1:

[0040] like Figure 1 As shown, the sterilizer rapid drainage device of this embodiment includes a gas output device 1, a tank body 3, a first solenoid valve 2, a second solenoid valve 4, a first manual ball valve and a second manual ball valve.

[0041] The gas output device 1 is connected to the first solenoid valve 2, which is connected to the tank body 3; the tank body 3 is connected to the second solenoid valve 4, which is connected to the drain joint assembly 5; optionally, a condenser is provided between the second solenoid valve 4 and the drain joint assembly 5, and the high-temperature water vapor and sewage in the discharge process are cooled by the condenser to prevent subsequent equipment from being affected by high temperature. The drain joint assembly 5 can be directly connected to the sewer or connected to the built-in drainage container 6 of the sterilizer according to the requirements of the usage scenario. The gas output device 1 can be an air pump, an air compressor or other directly provided gas source. In this embodiment, an air pump is used as the gas output device 1.

[0042] The gas output device 1 , the first solenoid valve 2 and the second solenoid valve 4 are electrically connected.

[0043] Specifically, a pressure-resistant and high-temperature resistant pipe is connected between the first solenoid valve 2 and the tank body 3. A pressure-resistant and high-temperature resistant pipe is connected between the second solenoid valve 4 and the tank body 3. The pressure-resistant and high-temperature resistant pipe can be made of a metal pipe or Teflon tube. A filter structure is provided at the point where the tank body 3 and the second solenoid valve 4 communicate.

[0044] When the drain joint assembly 5 is connected to the drain container 6 , a third communicating pipe is connected therebetween, and the third communicating pipe is connected to the upper end of the drain container 6 .

[0045] The first and second manual ball valves are respectively disposed between the gas output device 1 and the tank body 3 and between the drain joint assembly 5 and the tank body 3. Preferably, the first manual ball valve is disposed between the first solenoid valve 2 and the tank body 3, and the second manual ball valve is disposed between the second solenoid valve 4 and the tank body 3. The connecting pipes between the first and second manual ball valves and the tank body 3 are pressure-resistant and high-temperature-resistant pipes. The first and second manual ball valves are not shown in the drawings of this embodiment.

[0046] During use, the user can set a timed drain timer via the controller, draining wastewater when the sterilizer is not in operation, or directly drain the wastewater by pressing a button on the controller. Furthermore, by controlling the opening and closing of the second solenoid valve 4 during the draining state, two draining modes can be achieved. One is to close the second solenoid valve 4 during the draining state, allowing a certain amount of gas to accumulate inside the tank 3, and then open the second solenoid valve 4, achieving more efficient and faster drainage. The other is to open the second solenoid valve 4 during the draining state, and the gas output device 1 discharges the wastewater inside the tank 3 under stable gas output.

[0047] Example 2:

[0048] The difference between the second embodiment and the first embodiment is that there are multiple gas output devices 1, each of which is sequentially connected to a first solenoid valve 2 and a tank body 3. The connection points between the multiple first solenoid valves 2 and the tank body 3 are evenly spaced along the circumference of the tank body 3.

[0049] To sum up, the sterilizer rapid drainage device provided by the utility model, when discharging the sewage in the tank body of the sterilizer, under the control of the controller, the first solenoid valve and the second solenoid valve are opened and a certain pressure of gas is pumped into the tank body through the gas output device, and the sewage inside the tank body is squeezed out by the gas and finally discharged by the drainage joint assembly; the drainage design of the gas output device avoids the long-term erosion of the traditional water pump by sewage during use, causing blockage or failure; through the control of the first solenoid valve and the second solenoid valve, the discharge can be timed, and the discharge is controlled by the system under low temperature conditions, so that the pipeline and corresponding components will not be damaged due to overheating of the discharged sewage and steam.
