Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a steam bracket, a steam generator, and a steam sterilizer. Background Technology

[0002] Steam sterilizers utilize the principle of high-temperature steam sterilization. A steam generator heats water to produce high-temperature, high-pressure steam, which effectively eliminates most bacteria and viruses, providing reliable disinfection. Currently, such as Figure 1 As shown, commercially available steam generators typically have a steam support mounted on the heating plate to distribute the steam.

[0003] However, existing steam generators suffer from low heating efficiency, long heating time, and slow steam output due to the large amount of water at the bottom of the steam support during the steam generation process. This makes it difficult to meet the sterilizer's requirements for steam concentration and temperature, resulting in poor sterilization effect. In addition, for ease of assembly, the bottom surface of the steam support is generally in direct contact with the heating surface of the heating plate. Therefore, the steam support needs to be made of high-cost high-temperature resistant materials. However, it will still melt to a certain extent during operation due to the high temperature of the heating plate, affecting structural stability and shortening its service life.

[0009] In a preferred embodiment, at least one second steam outlet is evenly distributed on the top surface of the hollow protrusion, and the top surface edge of the hollow protrusion is provided with an upward flange.

[0010] A steam generating device includes a water tank and a heating plate. The bottom of the water tank has an opening, and the heating plate is located below the opening. The device includes a steam support as described in any of the above technical solutions. The steam support is installed on the opening, and the bottom surface of the steam support does not contact the heating plate. The interior of the cavity is not connected to the water tank.

[0031] Reference Figure 2-8 This invention describes a steam support 101, a steam generator 100, and a steam sterilizer according to an embodiment of the present invention.

[0032] In one embodiment, such as Figure 2-6 As shown, a steam support 101 is used in a steam generator 100. The steam generator 100 includes a water tank and a heating plate 104. The bottom of the water tank is provided with an opening, and the heating plate 104 is located below the opening. The steam support 101 has a cavity 1011 with an upper opening in the middle, and a side cavity 1012 with a lower opening is provided around the cavity 1011. The upper end of the side cavity 1012 is connected to at least one first steam outlet 1014. When the steam support 101 is installed on the opening, the bottom surface of the steam support 101 does not contact the heating plate 104, and the interior of the cavity 1011 is not connected to the water tank.

[0033] The steam support 101 may have a shape that matches the opening, such as a circle, rectangle, polygon or other shape. Correspondingly, the cavity 1011 may also be a circle, rectangle or other shape. The side cavity 1012 is arranged around the cavity 1011 and has an opening at the lower end. When the cavity 1011 is a circular cavity, the side cavity 1012 may be an annular side cavity. Preferably, the steam support 101 is an integrally formed structure.

[0034] When the commercially available steam support 101a is installed on the steam generator 100, the water surface 300a is as follows: Figure 1 As shown, the heating plate 104a heats the water inside the steam support 101a, and the generated steam flows out through the opening at the top of the steam support 101a and the steam outlet at the top side. Throughout the operation, the large volume of water to be heated results in a slow steam output and a long heating time.

[0035] In this embodiment, when the steam support 101 is installed into the steam generator 100, the water is only located between the bottom surface of the concave cavity 1011 and the upper surface of the heating plate 104, and within the side cavity 1012, with the water level 300 as shown. Figure 4As shown, this allows for maximum drainage of water in the middle area above the heating plate 104, significantly reducing the amount of water being heated. This enables the steam generator 100 to produce steam in a shorter time, shortening the heating time. Furthermore, due to the rapid steam discharge and large steam flow rate, higher concentration and temperature steam can be obtained in a short time. In the performance test of the steam generator 100, when the heating power of the heating plate 104 is 1.5 kW, the steam generator 100 with the steam support 101 can generate a large amount of steam within 2 minutes, and the maximum temperature of the steam can reach over 99°C. The concentration and temperature of the steam it produces are far higher than those of similar products currently on the market.

[0036] Meanwhile, the steam support 101 does not directly contact the heating plate 104, that is, the steam support 101 does not directly contact the heating area of ​​the heating plate 104, so as to avoid the steam support 101 being melted by the high temperature of the heating plate 104 during operation and to ensure the structural stability of the steam support 101.

[0037] In this embodiment, the lower part of the outer wall of the steam support 101 is provided with an installation limiting part 1017 that engages with the edge of the opening.

[0038] Furthermore, two inwardly oriented limiting protrusions are symmetrically provided on the edge of the opening at the bottom of the water tank. The maximum outer diameter of the mounting limiting part 1017 is the same as the inner diameter of the opening. The mounting limiting part 1017 includes a snap-fit ​​groove provided on the lower part of the outer wall of the steam support 101, and two limiting recesses are symmetrically provided on both sides of the snap-fit ​​groove.

[0039] In practice, the steam bracket 101 is placed into the opening by aligning the limiting recess with the limiting protrusion at the edge of the opening, and then the steam bracket 101 is rotated so that the limiting protrusion on the opening slides into the snap-fit ​​groove on the steam bracket 101, so that the steam bracket 101 can be detachably installed on the opening.

[0040] In this embodiment, the upper end of the side cavity 1012 is connected to at least two first steam outlets 1014 facing outward. The at least two first steam outlets 1014 can be symmetrically arranged on the top of the steam support 101 and are connected to the upper end of the side cavity 1012.

[0041] It should be noted that this embodiment is only one implementation method of this application. In actual implementation, the first steam outlet 1014 may also be arranged facing inward or upward, depending on the design requirements.

[0042] In this embodiment, the bottom surface of the cavity 1011 is provided with an upward hollow protrusion 1013, the lower end of the hollow protrusion 1013 is open, and the top of the hollow protrusion 1013 is provided with at least one second steam outlet 1015, which serves to exhaust steam and dissipate heat.

[0043] The hollow protrusions 1013 can be one or more; the hollow protrusions 1013 can be hollow cylindrical, conical or other shapes.

[0044] In specific implementation, when the bottom surface of the concave cavity 1011 is provided with only one hollow protrusion 1013, the hollow protrusion 1013 can be provided at the center of the bottom surface of the concave cavity 1011, so that steam flows out from the center of the steam support 101 and ensures that the steam output is evenly distributed.

[0045] In this embodiment, at least one second steam outlet 1015 is evenly distributed on the top surface of the hollow protrusion 1013, and the top edge of the hollow protrusion 1013 is provided with an upward flange 1016. The flange 1016 is arranged around the multiple second steam outlets 1015 to facilitate the concentrated upward movement of steam.

[0046] In another embodiment, such as Figure 4-6 As shown, a steam generating device 100 includes a water tank and a heating plate 104. The bottom of the water tank has an opening, and the heating plate 104 is located below the opening. It includes a steam support 101 as described in any of the above embodiments. The steam support 101 is installed on the opening, and the bottom surface of the steam support 101 does not contact the heating plate 104. The interior of the cavity 1011 is not connected to the water tank.

[0047] When the steam generator 100 is installed in the steam support 101, the water in the middle area above the heating plate 104 can be drained to the maximum extent, which greatly reduces the amount of water to be heated. Therefore, steam can be generated in a shorter time, shortening the heating time. Moreover, due to the fast steam discharge speed and large steam flow rate, steam with higher concentration and higher temperature can be obtained in a short time. At the same time, the steam support 101 does not directly contact the heating plate 104, which can prevent the steam support 101 from being melted by the high temperature of the heating plate 104 during operation, ensuring the structural stability of the steam support 101.

[0048] In this embodiment, the steam generator 100 includes a fixedly connected upper cover 102 and a bottom shell 114. The bottom surface of the upper cover 102 is recessed to form a water tank, and an opening is provided in the middle of the bottom surface of the upper cover 102.

[0049] The upper cover 102 is fixedly connected above the bottom shell 114. The upper cover 102 forms a water tank and an opening. The upper cover 102 and the bottom shell 114 together form the housing of the steam generator 100. The structure is simple and easy to install and disassemble. In specific implementation, the horizontal height of the top of the hollow protrusion 1013 is lower than the horizontal height of the edge of the upper cover 102.

[0050] In this embodiment, a connecting part is provided around the opening on the bottom surface of the upper cover 102, the heating plate 104 is fixedly connected to the connecting part, and the heating plate 104 and the upper cover 102 are sealed by a sealing ring 103 to ensure sealing performance.

[0051] In this embodiment, a hot air outlet 1021 is provided on one side of the top surface of the upper cover 102, and an installation cavity is formed between the upper cover 102 and the bottom shell 114. A hot air assembly is provided in the installation cavity, and the air duct of the hot air assembly is connected to the hot air outlet 1021.

[0052] The hot air assembly includes a fan 111, a guide vane 106, a heater 109, and a temperature sensor 107. The air outlet of the guide vane 106 is hinged with a baffle plate 105. The air inlet of the guide vane 106 is located at the air outlet of the fan 111, and a filter cover 115 is provided at the air inlet of the fan 111. The heater 109 and the temperature sensor 107 are located on the side of the fan 111.

[0053] The hot air generated by the hot air assembly is blown out through the hot air outlet 1021, which can accelerate the upward flow of steam, thereby further increasing the steam output speed.

[0054] In practice, the heater 109 is installed inside the heater bracket 108, and the temperature sensor 107 is installed on the top surface of the heater bracket 108 to detect the temperature of the heater 109 in real time. The heater 109 can be a PTC heater, which consists of a PTC ceramic heating element and an aluminum tube, and has the advantages of low thermal resistance, high heat exchange efficiency, and good safety performance; the temperature sensor 107 can be an NTC thermistor, whose resistance value decreases rapidly as the temperature rises.

[0055] More specifically, the steam generator 100 has an operation panel on its front side, and a control board bracket 113 corresponding to the position of the operation panel is provided in the mounting cavity. A control board 112 is provided on the control board bracket 113, and a circuit board 110 is connected to the control board 112. The circuit board 110 is connected to the heating plate 104, the fan 111, the heater 109 and the temperature sensor 107 respectively.

[0056] The user can control the sterilizer through the operation panel. The control board 112 senses the user's operation on the operation panel and transmits it to the circuit board 110. The circuit board 110 controls the heating plate 104, the fan 111 and the heater 109 to work. When the temperature sensor 107 detects that the temperature exceeds the safety threshold, it actively controls the heater 109 to stop working to ensure safety.

[0057] In yet another embodiment, such as Figure 7-8 As shown, a steam sterilizer includes a sterilization container 200 and a steam generator 100 as described in any of the above embodiments, wherein the sterilization container 200 is detachably placed on the steam generator 100.

[0058] The steam generator 100 heats the water in the water tank through the heating plate 104 to generate steam. The sterilization container 200 is used to place the items to be sterilized, and the bottom of the sterilization container 200 has multiple through holes. The steam output by the steam generator 100 can enter the inner cavity of the sterilization container 200 through these through holes to sterilize the items to be sterilized.

[0059] In practice, the steam generator 100 can simultaneously produce steam above the center and around the steam support 101 through the first steam outlet 1014 and the second steam outlet 1015, so that the steam is directed to the entire area below the disinfection container 200, allowing the steam to fill the entire disinfection container 200 more quickly and reach a higher steam temperature, thereby effectively improving the disinfection effect.

[0060] Other components and operations of the steam support, steam generating device, and steam sterilizer according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
