Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to steam generators and cooking equipment. Background Technology

[0002] In cooking appliances such as microwave ovens and microwave-steam-grill combos, the steam generator is a crucial component. It heats water to produce steam for cooking, preserving nutrients and enhancing flavor. However, in most areas, water quality is poor, containing a large amount of mineral ions. When heated, these ions concentrate and precipitate, forming scale inside the steam generator. Thick scale reduces heat transfer efficiency, increases energy consumption, and affects the uniformity and stability of steam, as well as cooking results. Moreover, steam generators have complex structures with many internal channels and corners, making scale extremely difficult to clean. Long-term accumulation of scale can breed bacteria, threaten food safety, and may also cause steam generator malfunctions and shorten its lifespan, resulting in inconvenience and losses for users. Utility Model Content

[0003] In view of this, the present invention provides a steam generator and cooking equipment to solve the problem of scale accumulation in existing steam generators.

[0004] In a first aspect, this utility model provides a steam generator, comprising:

[0005] The casing has a water inlet at the top;

[0006] A baffle plate, located inside the housing and below the inlet, is used to guide the incoming water to disperse outwards from the inlet and flow down the inner wall of the housing.

[0007] Beneficial effects: The baffle plate installed inside the steam generator serves two purposes. First, it acts as a shield, preventing water from boiling inside the shell and splashing onto the top cover and overflowing. Second, when water enters the shell from the inlet, the baffle plate guides the water flow from the center outwards and down the inner wall of the shell, thereby improving the water flow path, cleaning and rinsing the inner wall of the shell, reducing the possibility of scale adhering and depositing on the inner wall of the shell, facilitating cleaning and maintenance, extending the service life of the steam generator, reducing the failure rate, improving steam quality and cooking effect, and effectively solving the problem of scale accumulation in existing steam generators.

[0008] In one alternative implementation, the baffle is a plate-like structure that is higher in the middle and lower around the edges.

[0009] Beneficial effects: By adopting a design that is high in the middle and low around the edges, the baffle allows water falling into the baffle from the inlet to flow quickly in all directions along the slope of the baffle under the action of gravity. On the one hand, this increases the flow velocity of the water and improves the flushing effect of the incoming water on the inner wall of the shell. On the other hand, it can also effectively avoid the problem of water accumulation on the baffle.

[0010] In one alternative implementation, the baffle includes:

[0011] The main body of the baffle plate is in the shape of an arc plate, with the arc-shaped baffle plate protruding towards the water inlet, and the protruding part in the middle of the baffle plate corresponds to the position of the water inlet.

[0012] Beneficial effects: The baffle plate, with its arc-shaped design, is easy to manufacture. Furthermore, the raised section in the middle of the baffle plate corresponds to the water inlet, ensuring that water can diffuse from the highest raised section in the middle of the baffle plate outwards and then flow downwards from the surrounding areas. This avoids the problem of water not easily overflowing the raised section and spreading outwards if the highest raised section of the baffle plate does not correspond to the water inlet, resulting in uneven rinsing of the inner wall of the casing, and the existence of incomplete rinsing and dead zones.

[0013] In one alternative embodiment, the baffle has downwardly sloping, flared edges around its perimeter.

[0014] Beneficial effects: By setting downward-sloping and extending guide flanges around the baffle, the water flow can be further accelerated, the force of the water flow can be increased, and thus the flushing effect on the inner wall of the shell can be improved.

[0015] In one alternative embodiment, the baffle is fixedly disposed on the top inner side of the housing;

[0016] The shape of the baffle matches the cross-sectional shape of the shell, and there is a water passage gap between the baffle and the inner wall of the shell.

[0017] Beneficial effects: The baffle is positioned at the top of the inner side of the casing, allowing for flushing of the inner wall from a greater height, resulting in a larger flushed area and a better, more thorough flushing effect. Furthermore, by designing the baffle to match the cross-sectional shape of the casing, the fit between the baffle and the casing is improved, further facilitating a comprehensive, all-around flushing effect on the inner circumference of the casing.

[0018] In one alternative embodiment, the housing includes:

[0019] The top cover has a water inlet located on it, and a baffle plate is fixedly connected to the bottom of the top cover with a set interval between them.

[0020] Beneficial effects: By fixing the baffle plate to the bottom of the top cover, it is convenient to assemble and also convenient to remove or put into the housing along with the top cover, simplifying the assembly steps. Moreover, the baffle plate and the top cover are set at a certain interval, which can effectively prevent the baffle plate from sticking to the top cover and blocking the water inlet, thus avoiding the problem of poor water intake.

[0021] In one alternative embodiment, the baffle plate is provided with a first connecting part, and the upper cover is provided with a second connecting part, wherein the first connecting part and the second connecting part are connected by screws or welded together.

[0022] Beneficial effects: The baffle plate is fixed to the top cover by screws or welding, making the baffle plate more secure and stable, effectively ensuring its stability under the impact of water flow. Furthermore, the screw or welding method also effectively ensures the airtightness of the steam generator's interior.

[0023] In one alternative embodiment, the bottom wall of the housing is provided with a water outlet, and the bottom wall of the housing is configured to gradually slope downward from all sides toward the water outlet.

[0024] Beneficial effects: The downward-sloping, tapering design of the shell's bottom wall allows water to collect and drain smoothly through the outlet, preventing water accumulation and improving drainage efficiency. This effectively avoids scale buildup on the bottom wall due to long-term water accumulation. Furthermore, the downward-sloping bottom wall increases water flow velocity, accelerating drainage and effectively flushing the bottom wall, further reducing the likelihood of scale buildup.

[0025] In one alternative embodiment, the housing includes a detachably connected base and a top cover, with the water inlet located at the center of the top cover and the water outlet located at the center of the bottom wall of the base.

[0026] Beneficial effects: The housing's design, featuring a detachable base and top cover, facilitates easy cleaning and maintenance of the interior. Positioning the water inlet at the center of the top cover effectively ensures even water distribution and balanced force distribution on the baffles. Positioning the water outlet at the center of the base effectively ensures drainage and maintains the overall balance and stability of the steam generator.

[0027] Secondly, this utility model also provides a cooking device, including a steam generator according to any of the above embodiments. Attached Figure Description

[0047] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0048] The following is combined Figures 1 to 9 The following describes embodiments of the present invention.

[0049] According to an embodiment of the present invention, in one aspect, the present invention provides a steam generator 10, including a housing 11 and a baffle plate 12. The top of the housing 11 is provided with a water inlet 101, and the baffle plate 12 is disposed inside the housing 11 and located below the water inlet 101, for guiding the water inlet to disperse from the water inlet 101 to the surrounding area and flow down along the inner wall of the housing 11.

[0050] In the above embodiment, the baffle plate 12 installed inside the steam generator 10 serves two purposes: firstly, it acts as a shield to prevent water from boiling inside the housing 11 and splashing onto the upper cover 111 of the housing 11 and overflowing; secondly, when water enters the housing 11 from the inlet 101, the baffle plate 12 guides the water flow from the center outwards and down the inner wall of the housing 11, thereby improving the water flow path, cleaning and rinsing the inner wall of the housing 11, reducing the possibility of scale adhering and depositing on the inner wall of the housing 11, facilitating cleaning and maintenance, extending the service life of the steam generator 10, reducing the failure rate, improving steam quality and cooking effect, and effectively solving the problem of scale accumulation in the existing steam generator 10.

[0051] Specifically, the baffle plate 12 is horizontally positioned below the water inlet 101. The baffle plate 12 extends around its periphery towards the inner peripheral wall of the housing 11, reaching a position where a water passage gap is formed between it and the inner peripheral wall of the housing 11. This design ensures that water entering from the water inlet 101 can be dispersed along the baffle plate 12 and flow down along the inner peripheral wall of the housing 11. Simultaneously, the water passage gap ensures that the generated steam can be discharged through the air outlet 103 at the top of the housing 11.

[0052] In some embodiments, combined with Figures 2 to 6 As shown, the baffle plate 12 is a plate-shaped structure that is high in the middle and low around the edges.

[0053] In the above embodiment, the baffle 12 adopts a design that is high in the middle and low around the edges, which allows the water falling from the inlet 101 onto the baffle 12 to flow rapidly around the edges along the slope of the baffle 12 under the action of gravity. On the one hand, this increases the flow rate of the water and improves the flushing effect of the incoming water on the inner peripheral wall of the housing 11. On the other hand, it can also effectively avoid the problem of residual water on the baffle 12.

[0054] Furthermore, in this embodiment, the highest point in the middle of the baffle plate 12 corresponds to the position of the water inlet 101, thereby ensuring that the water can flow from the highest point in the middle to the surrounding areas. This avoids the situation where the highest point in the middle of the baffle plate 12 does not correspond to the position of the water inlet 101, which would make it difficult for the water to overflow the highest point. This would result in uneven rinsing effect on the inner peripheral wall of the housing 11, and problems such as inadequate rinsing and dead corners.

[0055] It should be noted that in this embodiment, the baffle 12 can be arc-shaped, or it can be umbrella-shaped, cone-shaped, etc.

[0056] In some embodiments, the baffle plate 12 includes a baffle plate body 121, which is arc-shaped. The arc-shaped baffle plate body 121 protrudes towards the water inlet 101, and the protruding part in the middle of the baffle plate body 121 corresponds to the position of the water inlet 101.

[0057] In the above embodiment, the baffle 12 is made of an arc-shaped plate, which facilitates its processing and forming. Furthermore, the protruding portion in the middle of the baffle body 121 corresponds to the position of the water inlet 101, ensuring that the incoming water can diffuse from the highest protruding portion in the middle of the baffle body 121 to the surrounding areas, and then flow downwards from the surrounding areas. This avoids the situation where the highest protruding portion in the middle of the baffle 12 does not correspond to the position of the water inlet 101, causing the water flow to be difficult to overflow the protruding portion and diffuse outwards. This would result in uneven rinsing of the inner peripheral wall of the shell 11, with some areas not being thoroughly rinsed and having dead corners.

[0058] In this embodiment, a baffle plate 12 is installed inside the housing 11 of the steam generator 10. The baffle plate 12 has two functions: First, it prevents water vapor from splashing onto the top cover 111 of the housing 11 when it boils inside, providing a good shielding effect. The generated steam can pass freely through the gap between the baffle plate 12 and the inner wall of the housing 11, while the water vapor is blocked by the baffle plate 12, preventing the water vapor from being sprayed out in a concentrated manner. For example, when water boils, it boils vigorously and will be concentrated and splashed up. The baffle plate 12 can effectively prevent water vapor from overflowing. Second, the baffle plate 12 is arc-shaped. When water enters the housing 11 of the steam generator 10 from the inlet 101, the water will flow from the center to the periphery along the shape of the baffle plate 12 and flow down the inner wall of the housing 11. This process can clean the housing 11, thereby preventing scale from adhering to the housing 11.

[0059] In some embodiments, the baffle plate 12 has downwardly inclined guide flanges 122 around its periphery.

[0060] In the above embodiment, the downwardly inclined guide flanges 122 provided around the baffle 12 can further accelerate the water flow, increase the force of the water flow, and thus improve the flushing effect on the inner wall of the housing 11.

[0061] Specifically, the flow-guiding fold 122 is an inclined fold extending downward from the four edges of the baffle plate 12. The angle between the tangent of the convex vertex of the arc-shaped baffle plate body 121 and the horizontal plane is set to α1, and the angle between the flow-guiding fold 122 and the horizontal plane is set to α2, where α1 < α2 < 90°. Through the above angle design, it can be ensured that the water flow is faster and has a greater impact force when flowing down from all sides, resulting in a better flushing effect on the shell 11. Moreover, α2 < 90° can also guide the water flow to slide down towards the inner wall of the shell 11.

[0062] In some embodiments, the baffle plate 12 is fixedly disposed on the inner top of the housing 11; the shape of the baffle plate 12 matches the shape of the cross section of the housing 11, and there is a water passage gap between the periphery of the baffle plate 12 and the inner wall of the housing 11.

[0063] In the above embodiment, the baffle 12 is disposed at the top of the inner side of the housing 11, thereby enabling the inner wall of the housing 11 to be rinsed from a height as much as possible, resulting in a larger area of ​​the inner wall of the housing 11 being rinsed, and a better and more thorough rinsing effect. Furthermore, by setting the baffle 12 to match the shape of the cross-section of the housing 11, the matching degree between the baffle 12 and the housing 11 can be improved, which is more conducive to forming an all-round, dead-angle-free rinsing effect on the inner peripheral wall of the housing 11.

[0064] In some embodiments, such as Figure 1 and Figure 2 As shown, the housing 11 includes an upper cover 111, the water inlet 101 is opened on the upper cover 111, and the baffle 12 is fixedly connected below the upper cover 111 and has a set interval between it and the upper cover 111.

[0065] In the above embodiment, by fixing the baffle 12 to the bottom of the upper cover 111, it is convenient to assemble and also convenient to remove or put into the housing 11 along with the upper cover 111, simplifying the assembly steps. Moreover, the baffle 12 and the upper cover 111 are set at a certain interval, which can effectively prevent the baffle 12 from sticking to the upper cover 111 and blocking the water inlet 101, thus avoiding the problem of poor water intake.

[0066] Specifically, in this embodiment, the water inlet 101 is located on the upper cover 111 and is connected to an external water pipe. The baffle 12 is detachably and fixedly connected to the lower part of the upper cover 111 or is non-detachably and fixedly connected to the lower part of the upper cover 111 by welding or other means. Specifically, the baffle 12 is provided with a first connecting part 123, and the upper cover 111 is provided with a second connecting part 1111. The upper cover 111 and the baffle 12 are connected through the second connecting part 1111 and the first connecting part 123. The first connecting part 123 and the second connecting part 1111 can be snapped together, screwed together, or welded together.

[0067] In some embodiments, the baffle plate 12 is provided with a first connecting portion 123, and the upper cover 111 is provided with a second connecting portion 1111. The first connecting portion 123 and the second connecting portion 1111 are connected by screws or welded together.

[0068] In the above embodiments, the baffle plate 12 and the upper cover 111 are fixed by means of screw connection or welding, which makes the baffle plate 12 more secure and stable, and can effectively ensure the stability of the baffle plate 12 when subjected to water flow impact. Furthermore, the fixing by screw connection or welding can also effectively ensure the airtightness of the steam generator 10.

[0069] In some alternative embodiments, the first connecting part 123 is a first press-formed part that protrudes upward from the baffle 12, and the second connecting part 1111 is a second press-formed part that is recessed downward from the top cover 111. The first press-formed part and the second press-formed part are fixed by welding or by screws.

[0070] In some alternative embodiments, the first connecting part 123 is a connecting hole opened on the baffle 12, and the second connecting part 1111 is a bolt post provided below the upper cover 111. The first connecting part 123 and the second connecting part 1111 are connected by screws.

[0071] Preferably, in this embodiment, there are multiple first connecting parts 123, which are spaced apart on the baffle 12. There are also multiple second connecting parts 1111, and the multiple first connecting parts 123 and the multiple second connecting parts 1111 are connected one-to-one. This design can further improve the stability of the baffle 12 structure.

[0072] In some embodiments, such as Figure 2 , Figures 7 to 9 As shown, the bottom wall of the housing 11 is provided with a water outlet 102, and the bottom wall of the housing 11 is constructed to be tapered in a shape that gradually slopes downward from all sides toward the water outlet 102.

[0073] In the above embodiment, the bottom wall of the housing 11 adopts a downwardly sloping, converging design, which allows water on the bottom wall of the housing 11 to collect and be smoothly discharged through the outlet 102, preventing water accumulation and improving drainage efficiency. This effectively avoids the problem of scale buildup on the bottom wall of the housing 11 due to long-term water accumulation. Furthermore, the downwardly sloping bottom wall also increases the water flow rate and accelerates water discharge, thereby effectively flushing the bottom wall of the housing 11 and further reducing the possibility of scale buildup.

[0074] Specifically, the outlet 102 is located at the center of the bottom wall, and the bottom wall of the shell 11 slopes inward from the periphery to the center, so that water gathers in the center and is discharged from the outlet 102.

[0075] In some embodiments, the housing 11 includes a detachably connected base 112 and a top cover 111, the water outlet 102 is located at the center of the bottom wall of the base 112, and the water inlet 101 is located at the center of the top cover 111.

[0076] In the above embodiment, the housing 11, with its detachably connected base 112 and top cover 111, facilitates cleaning and maintenance of the interior. By placing the water inlet 101 at the center of the top cover 111, it effectively ensures that the water is evenly distributed to the surrounding area, while also ensuring balanced force on the baffle plate 12. By placing the water outlet 102 at the center of the base 112, it effectively ensures drainage while maintaining the overall balance and stability of the steam generator 10.

[0077] Specifically, the base 112 and the top cover 111 are connected by screws. Multiple sets of screw connection parts are correspondingly arranged circumferentially on both the base 112 and the top cover 111. The connection and fixation of the base 112 and the top cover 111 are achieved by connecting these multiple sets of screw connection parts one-to-one with the screws. Optionally, a sealing ring 18 is also provided between the base 112 and the top cover 111. Specifically, an annular sealing groove is provided on the upper end face of the base 112, and an annular connecting edge is provided on the outer periphery of the top cover 111. The sealing ring 18 is embedded in the annular sealing groove. After the base 112 and the top cover 111 are connected, the annular connecting edge presses against the sealing ring 18 to form a seal.

[0078] Furthermore, the base 112 includes a base bottom wall 1122 and a base peripheral wall 1121. The water outlet 102 is located at the center of the base bottom wall 1122. The baffle plate 12 can guide the incoming water to the base peripheral wall 1121 for rinsing. An annular sealing groove is formed on the upper surface of the base peripheral wall 1121. A water inlet connecting pipe 13 is provided at the water inlet 101, and a water outlet connecting pipe 14 is provided at the water outlet 102. The upper cover 111 also has an air outlet 103, and an air outlet connecting pipe 14 is provided at the air outlet 103. The water inlet connecting pipe 13 and the air outlet connecting pipe 14 are connected to the upper cover 111 by welding or are integrally formed with the upper cover 111. The water outlet connecting pipe is connected to the base 112 by welding or is integrally formed with the base 112.

[0079] In some embodiments, the housing 11 is a rectangular box structure, and the baffle 12 is a strip plate. The baffle 12 has a baffle body 121 and a flow-guiding folded edge 122 disposed around the baffle body 121. The longitudinal section of the baffle body 121 is arc-shaped, and the flow-guiding folded edge 122 is inclined downward. Preferably, the flow-guiding folded edge 122 is an inclined straight edge.

[0080] In this embodiment, the steam generator 10 also includes a sensor 16, a dry-burning tube 15, and a thermal cut-off device 17. The sensor 16, the dry-burning tube 15, and the thermal cut-off device 17 are all installed at the bottom of the base 112.

[0081] The main improvements and advantages of the steam generator 10 provided in this application are as follows:

[0082] 1) The added baffle 12 can act as a shield to prevent water from splashing onto the top cover 111 when it boils at high temperature;

[0083] 2) The added baffle 12 can guide the incoming water to the inner peripheral wall of the housing 11, which can flush the peripheral wall of the base 112 and reduce scale.

[0084] 3) The bottom wall of the base 112 is designed to gradually slope towards the outlet 102 from all sides to collect water and discharge it, preventing the problem of scale buildup due to water accumulation after long-term use.
