Abstract
Description
Technical Field
[0001] This application relates to the field of small household appliances, and in particular to a steam generator and cooking appliance. Background Technology
[0002] Open-type steam generators, due to their low steam temperature (not exceeding 100°C) and lack of temperature adjustment, cannot perform precise cooking of food and require a long steaming time. To address this, some have designed steam generators capable of producing high-temperature steam exceeding 100°C. However, current steam generators capable of producing steam above 100°C typically involve secondary heating of the generated steam. The steam generation chamber of this type of generator is a closed cavity, making internal cleaning difficult. Utility Model Content
[0003] Therefore, it is necessary to provide a steam generator and cooking appliance that can produce high-temperature steam above 100°C and is easy to clean.
[0004] A steam generating device includes: a base, a cover, and a heating element; the cover is detachably connected to the base, and the cover and the base enclose a relatively closed steam generating chamber, the steam generating chamber having an outlet for outputting steam, the outlet being located on the cover; the heating element is used to heat water in the steam generating chamber to generate steam.
[0005] The steam generator provided in this application, because the cover and base enclose a relatively closed steam generating chamber, allows steam generated in the chamber to exit only through the outlet. Therefore, when the steam generation rate exceeds the outlet's exit rate, a large amount of steam remains trapped within the chamber, increasing the pressure and temperature within the chamber, resulting in high-temperature steam exceeding 100°C. Using this high-temperature steam to cook food shortens cooking time and improves efficiency. Since the cover is detachably connected to the base, it can be removed for easy cleaning of the steam generating chamber's interior.
[0006] In one embodiment, the cover is screwed or snapped onto the base.
[0007] In this way, it is very convenient to install and remove the cover and base, making it easy to use and clean.
[0008] In one embodiment, the base includes a first main body that encloses a first chamber and a first connecting portion disposed around the first main body, and the cover includes a second main body that encloses a second chamber and a second connecting portion disposed around the second main body. The first connecting portion and the second connecting portion are connected in a cooperative manner, and the first chamber and the second chamber are connected to each other to form the steam generating chamber.
[0009] In this way, the edge of the base is connected to the edge of the cover, and the inner cavity of the base and the inner cavity of the cover constitute the steam generating chamber, which ensures the capacity of the steam generating chamber and makes it easy to seal the steam generating chamber.
[0010] In one embodiment, the first connecting portion is screwed or snapped into the second connecting portion.
[0011] Thus, the connection method is simple, and it is easy to install or remove the cover, making it convenient to use and easy to clean.
[0012] In one embodiment, the first connecting part is provided with a first thread, and the second connecting part (22) is provided with a second thread. The first thread and the second thread are engaged to achieve a screw-in connection between the first connecting part and the second connecting part; or, the first connecting part is provided with a plurality of first protrusions spaced apart circumferentially, and the second connecting part is provided with a plurality of second protrusions spaced apart circumferentially. The first protrusion or the second protrusion is provided with a slot. By screwing the first connecting part and the second connecting part relative to each other, the second protrusion or the first protrusion can be inserted into the slot to achieve a screw-in connection between the first connecting part and the second connecting part.
[0013] Thus, the cover and base are screwed together using a threaded connection. The threaded structure is simple, the connection is tight, and the threaded connection provides a certain degree of sealing. Alternatively, the cover and base can be screwed together using a protrusion and a groove. This structure is very simple and easy to install and disassemble.
[0014] In one embodiment, a sealing element is further provided between the first connecting portion and the second connecting portion, the sealing element sealing the connection between the first connecting portion and the second connecting portion.
[0015] This ensures that steam does not leak from the connection between the cover and the base.
[0016] In one embodiment, the first connecting portion includes a first axial portion extending axially from the first body along the base and a first radial portion extending radially outward from the first axial portion along the base; the second connecting portion includes a second axial portion extending axially from the second body along the cover and a second radial portion extending radially outward from the second axial portion along the cover; the sealing member is disposed between the first radial portion and the second radial portion; or, the sealing member is disposed between the first axial portion and the second axial portion.
[0017] In this way, the connection between the cover and the base is tight.
[0018] In one embodiment, one or more air outlets are provided, and the total air outlet area is equivalent to the cross-sectional area of a circular hole with a diameter of D, where 0 < D ≤ 10 mm.
[0019] In this way, the steam outlet will not be very large, and by adjusting the input power of the heating element, the steam temperature in the steam generating chamber can be controlled within the range of 100℃ to 120℃.
[0020] In one embodiment, the steam generating device further includes a sensor that extends at least partially into the steam generating chamber to collect temperature or pressure information within the steam generating chamber.
[0021] Thus, the temperature or pressure inside the steam generating chamber can be monitored in a timely manner using sensors. A cooking appliance includes the steam generating device described above, the cooking appliance having a cooking chamber, the steam outlet connecting the steam generating chamber and the cooking chamber; or, the steam generating chamber constitutes the cooking chamber, and the steam outlet connects the cooking chamber to the outside.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0034] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application's specification are for illustrative purposes only and do not represent the only possible implementation.
[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0036] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0037] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0038] Please see Figures 1 to 3 This application provides a steam generating device, including: a base 10, a cover 20, and a heating element 30. The cover 20 is detachably connected to the base 10, and the cover 20 and the base 10 enclose a relatively closed steam generating chamber 101. The steam generating chamber 101 has an outlet 102 for outputting steam, which is opened in the cover 20. The heating element 30 is used to heat the water in the steam generating chamber 101 to generate steam.
[0039] It can be understood that "the cover body 20 and the base 10 enclose a relatively closed steam generation cavity 101" means that the steam generation cavity 101 is a relatively closed chamber, and there will be no gas leakage at the connection between the cover body 20 and the base 10, and the steam in the steam generation cavity 101 can only be discharged from the air outlet 102.
[0040] In the steam generation device provided by the present application, since the cover body 20 and the base 10 enclose a relatively closed steam generation cavity 101, and the steam generated in the steam generation cavity 101 can only be discharged from the air outlet 102. Therefore, when the generation rate of steam is greater than the outlet rate of the air outlet 102, a large amount of steam in the steam generation cavity 101 cannot be discharged in time, which increases the pressure in the steam generation cavity 101, and thus the steam temperature in the steam generation cavity 101 is increased, and high-temperature steam exceeding 100 °C can be formed. Using these high-temperature steams exceeding 100 °C to steam food is beneficial to shortening the cooking time of food and improving cooking efficiency. Since the cover body 20 is detachably connected to the base 10, the cover body 20 can be detached and then the inside of the steam generation cavity 101 can be cleaned, which is convenient for cleaning.
[0041] In one embodiment, the heating element 30 is a heating tube, but it is not limited thereto. In other embodiments, the heating element 30 can also be a heating plate.
[0042] Furthermore, the cover body 20 and the base 10 are screwed or snapped together. In this way, it is very convenient to install and拆卸 the cover body 20 and the base 10, which is convenient for use and cleaning.
[0043] Please refer to Figure 4 , the base 10 includes a first main body 11 that encloses a first chamber 13 and a first connecting portion 12 provided on the periphery of the first main body 11. In this embodiment, the heating element 30 is disposed at the bottom of the first main body 11. The cover body 20 includes a second main body 21 that encloses a second chamber 23 and a second connecting portion 22 provided on the periphery of the second main body 21. The first connecting portion 12 and the second connecting portion 22 are cooperatively connected, and the first chamber 13 and the second chamber 23 are connected and communicate to form the steam generation cavity 101. In this way, it is equivalent to connecting the edge portions of the base 10 and the cover body 20, and the inner cavities of the base 10 and the cover body 20 form the steam generation cavity 101, which ensures the capacity of the steam generation cavity 101 and is easy to seal the steam generation cavity 101. In this embodiment, the cross-section of the second main body 21 is the same as the upper half of the shape of a "convex" character.
[0044] Furthermore, the first connecting part 12 and the second connecting part 22 are screwed together or snapped together, which is a simple connection method and makes it easy to install or remove the cover 20, thus making it convenient to use and easy to clean. Preferably, the first connecting part 12 and the second connecting part 22 are screwed together, which makes it even more convenient to install or remove the cover 20.
[0045] Please see Figure 4 and Figure 5 In one embodiment, the first connecting part 12 is provided with a first thread 121, and the second connecting part 22 is provided with a second thread 221. The first thread 121 and the second thread 221 are engaged to achieve a screw-in connection between the first connecting part 12 and the second connecting part 22. In this embodiment, the screw-in connection between the cover 20 and the base 10 is achieved through a threaded connection. The threaded connection structure is simple and the connection is tight, and the threaded connection can provide a certain sealing effect.
[0046] Please see Figures 6 to 8 In another embodiment, the first connecting portion 12 has a plurality of first protrusions 122 spaced apart circumferentially, and the second connecting portion 22 has a plurality of second protrusions 222 spaced apart circumferentially. The second protrusions 222 have slots 224. By screwing the first connecting portion 12 and the second connecting portion 22 relative to each other, the first protrusions 122 can be engaged into the slots 224, thereby achieving a screw-on connection between the first connecting portion 12 and the second connecting portion 22. For ease of description, the space between two adjacent first protrusions 122 is defined as a first notch 123, and the space between two adjacent second protrusions 222 is defined as a second notch 223. Please refer to... Figure 9 As shown, when installing the cover 20, place the cover 20 on the base 10, align the second protrusion 222 with the first notch 123, and then rotate the cover 20 so that the first protrusion 122 can be engaged in the slot 224. The disassembly process is the reverse. Alternatively, the slot 224 can be provided on the first protrusion 122. Specifically, the first protrusion 122 has a slot 224. By screwing the first connecting part 12 and the second connecting part 22 relative to each other, the second protrusion 222 can be engaged in the slot 224, thereby achieving a screw-on connection between the first connecting part 12 and the second connecting part 22. In this embodiment, the screw-on connection between the cover 20 and the base 10 is achieved by the cooperation of the protrusion and the slot 224. The structure is very simple, and installation and disassembly are very convenient.
[0047] Taking the second protrusion 222 having a slot 224 as an example, the specific method of forming the slot 224 can be as follows: the second protrusion 222 is folded at the middle position in the width direction, and the end of the second protrusion 222 away from the second body 21 is folded downwards towards the second body 21, so that the second protrusion 222 forms two layers, and the slot 224 is formed between the two layers. However, it is not limited to this. In other embodiments, the slot 224 can also be formed on the second protrusion 222 by cutting. For the structure of forming the slot 224 by folding, the thickness of the second protrusion 222 can be set to be thinner, so as to facilitate folding; while for the structure of forming the slot 224 by cutting, the thickness of the second protrusion 222 can be set to be thicker, so as to ensure that the slot 224 is cut out on the inner side of the second protrusion 222. The first protrusion 122 having a slot 224 is similar, and will not be described in detail here.
[0048] Please see Figure 4 and Figure 6 Furthermore, a sealing element 24 is provided between the first connecting portion 12 and the second connecting portion 22, sealing the connection between the first connecting portion 12 and the second connecting portion 22. This ensures that steam does not leak from the connection between the cover 20 and the base 10. Furthermore, the sealing element 24 is a silicone or rubber sealing ring, which facilitates a good seal. Furthermore, the first connecting portion 12 and / or the second connecting portion 22 may have a groove, and the sealing element 24 is disposed within the groove, thus preventing the sealing element 24 from easily falling off and providing a better seal at the connection between the first connecting portion 12 and the second connecting portion 22.
[0049] Please see Figure 5 and Figure 7 Furthermore, the first connecting portion 12 includes a first axial portion 125 extending axially from the first body 11 along the base 10 and a first radial portion 126 extending radially outward from the first axial portion 125 along the base 10. The second connecting portion 22 includes a second axial portion 225 extending axially from the second body 21 along the cover 20 and a second radial portion 226 extending radially outward from the second axial portion 225 along the cover 20. When the cover 20 is installed on the base 10, the second axial portion 225 extends into the inside of the first axial portion 125, and the second radial portion 226 rests on the first radial portion 126; or, the first axial portion 125 extends into the inside of the second axial portion 225, and the second radial portion 226 rests on the first radial portion 126.
[0050] Please see Figure 4 and Figure 5 In this embodiment, the first thread 121 is disposed on the first axial portion 125, the second thread 221 is disposed on the second axial portion 225, and the seal 24 is disposed between the first radial portion 126 and the second radial portion 226.
[0051] Please see Figures 6 to 8 In this embodiment, the first protrusion 122 is disposed outside the first radial portion 126, the second protrusion 222 is disposed outside the second radial portion 226, and the seal 24 is disposed between the first axial portion 125 and the second axial portion 225.
[0052] Please see Figure 4 In this embodiment, the vent 102 is located on the cover 20, thus preventing water in the steam generating chamber 101 from leaking out through the vent 102. Further, one or more vents 102 are provided, and the total venting area of the vents 102 is equivalent to the cross-sectional area of a circular hole with diameter D, where 0 < D ≤ 10 mm. In some specific embodiments, D can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, or 10 mm, etc. That is, the total venting area of the vents 102 is S, where 0 < S ≤ 25π mm. 2 Therefore, the steam outlet 102 will not be very large, and the steam temperature in the steam generating chamber 101 can be controlled within the range of 100℃ to 120℃ by adjusting the input power of the heating element 30. Since higher steam temperature results in higher steam pressure, the walls of the base 10 and the cover 20 need to be thicker, thus increasing costs. Furthermore, when cooking food with steam, higher steam temperatures cause faster protein denaturation, leading to significant food shrinkage and affecting the texture. Considering both cost and cooking requirements, controlling the steam temperature between 100℃ and 120℃ is more suitable. The shape of the steam outlet 102 can be any shape, such as circular, elliptical, square, hexagonal, etc., as long as the total steam outlet area of the steam outlet 102 meets the above requirements.
[0053] In this embodiment, the air outlet 102 is configured as a small hole, which allows steam to be discharged when steam is generated in the steam generating chamber 101. When the steam generation rate is greater than the steam discharge rate through the small hole, high pressure is formed in the steam generating chamber 101, resulting in steam with a temperature higher than 100°C. The higher the input power of the heating element 30, the faster the steam generation rate, resulting in higher steam pressure and higher steam temperature in the steam generating chamber 101.
[0054] Furthermore, a pressure relief valve 60 is provided on the cover 20. The pressure relief valve 60 is used to automatically open to relieve pressure when the steam pressure in the steam generating chamber 101 exceeds a safety threshold. Thus, in the event of an accident causing the steam pressure in the steam generating chamber 101 to exceed the safety threshold, the pressure relief valve 60 can relieve pressure in a timely manner, thereby ensuring the safety performance of the steam generating device. The pressure relief valve 60 can be a pressure relief valve from the prior art; as long as the pressure relief valve 60 can open to relieve pressure when the steam pressure in the steam generating chamber 101 exceeds the safety threshold, further details are omitted here.
[0055] Further, please see Figure 1 The steam generating device also includes a water tank 70 and a water pump 80. The inlet of the water pump 80 is connected to the inner cavity of the water tank 70, and the outlet of the water pump 80 is connected to the steam generating chamber 101. The water pump 80 is used to pump water from the water tank 70 into the steam generating chamber 101. By setting up the water tank 70 and the water pump 80, the steam generating chamber 101 can be actively and promptly replenished with water, so that the steam generating chamber 101 only needs a small amount of water, thereby improving the steam generation efficiency.
[0056] Furthermore, a one-way valve (not shown) is provided in the flow path between the water pump 80 and the steam generating chamber 101. The flow direction of the one-way valve is from the water pump 80 to the steam generating chamber 101. This prevents steam from flowing back into the water pump 80 and damaging it, thus improving operational safety. In this embodiment, the water pump 80 and the steam generating chamber 101 are connected by a pipe 81, and the one-way valve is installed on the pipe 81.
[0057] Furthermore, the steam generating device also includes a sensor 40, which at least partially extends into the steam generating chamber 101 to collect temperature or pressure information within the steam generating chamber 101. It is understood that the sensor 40 is connected to a controller 50, which is electrically connected to the heating element 30. The controller 50 can control the heating element 30 based on the temperature or pressure information collected by the sensor 40, thereby adjusting the input power of the heating element 30. Once the size of the outlet 102 is determined, the steam generation rate mainly depends on the input power of the heating element 30. The higher the input power of the heating element 30, the faster the steam generation rate, and the higher the steam pressure and temperature when the steam generating chamber 101 reaches a dynamic equilibrium state. It is understood that "the steam generating chamber 101 reaching a dynamic equilibrium state" means that the steam generation rate and output rate within the steam generating chamber 101 are the same, at which point the steam pressure and steam temperature remain at a constant value and no longer change. When the steam generating chamber 101 reaches a dynamic equilibrium state, there is a one-to-one correspondence between the steam pressure within the steam generating chamber 101 and the input power of the heating element 30. Since there is also a one-to-one correspondence between steam pressure and steam temperature, there is also a one-to-one correspondence between the steam temperature within the steam generating chamber 101 and the input power of the heating element 30. In other words, one input power corresponds to one steam pressure and one steam temperature. Therefore, the one-to-one correspondence between the pressure or temperature of the steam generating chamber 101 when it reaches a dynamic equilibrium state and the input power of the heating element can be measured and stored in the controller 50. This allows the controller 50 to adjust the input power of the heating element 30 according to the cooking pressure or temperature required for different cooking stages in different cooking menus, or it can adjust the input power of the heating element 30 according to different set target temperatures or pressures. By adjusting the input power of the heating element 30, the steam temperature can be regulated.
[0058] When the steam generator is operating, sensor 40 collects temperature or pressure information in the steam generation chamber 101 in real time. Controller 50 can monitor the temperature or pressure in the steam generation chamber 101 based on this information and adjust the input power of heating element 30 accordingly to ensure the generation of steam at the target temperature or pressure. Furthermore, controller 50 is connected to an alarm device. When the temperature or pressure collected by sensor 40 exceeds a threshold, the alarm device will alert the user.
[0059] In one embodiment, sensor 40 is a temperature sensor that collects temperature information within the steam generating chamber 101. When the water in the steam generating chamber 101 boils and generates steam, the steam temperature is the same as the water temperature. Therefore, sensor 40 can collect both the water temperature and the steam temperature. Figure 1In the illustrated embodiment, sensor 40 is disposed on base 10, and sensor 40 extends at least partially from the bottom wall of base 10 into steam generating chamber 101. However, this is not a limitation. In other embodiments, sensor 40 may also extend at least partially from the side wall of base 10 into steam generating chamber 101. Alternatively, sensor 40 may be disposed on cover 20, and sensor 40 may extend at least partially from the top wall or side wall of cover 20 into steam generating chamber 101. In another embodiment, sensor 40 is a pressure sensor that collects pressure information within steam generating chamber 101.
[0060] Please see Figures 1 to 3 This application also provides a cooking appliance, including the steam generating device as described above. The cooking appliance has a cooking chamber 103, and a steam outlet 102 connects the steam generating chamber 101 and the cooking chamber 103, so that steam is output from the steam outlet 102 for use in the cooking chamber 103. In this embodiment, the cooking appliance also includes a base 91 and a pot body 92. The pot body 92 is provided with the cooking chamber 103. The water tank 70 and the pot body 92 are both disposed above the base 91. The water pump 80, the base 10, and the cover 20 are all disposed inside the base 91. The steam generating chamber 101 is disposed below the cooking chamber 103, but it is not limited to this. In other embodiments, the steam generating chamber 101 can be set to a larger volume, and the steam generating chamber 101 can be directly set as the cooking chamber 103. That is, the steam generating chamber 101 of the steam generating device constitutes the cooking chamber 103 of the cooking appliance. The steam outlet 102 connects the cooking chamber 103 to the outside, so the steam temperature in the steam generating chamber 101 is the steam temperature during cooking.
[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
