Description

Technical Field

[0001] This utility model belongs to the field of cooking appliance technology, specifically relating to a steam oven. Background Technology

[0002] Currently, ovens with steam functions typically achieve tender roasting by placing steam jets at the top, back, or side of the cooking cavity. To achieve steam injection, a steam generation system, including a miniature water pump, thin water pipes, and atomizing nozzles, is usually installed inside or outside the oven. During operation, the pump delivers water from the reservoir through the thin water pipes to the high-temperature nozzles, where it is instantly vaporized and sprayed out. This approach has significant drawbacks in practical use: First, the thin water pipes and tiny nozzle orifices are highly susceptible to limescale buildup due to mineral precipitation at high temperatures. Once clogged, not only is the steam supply interrupted, affecting cooking results, but unclogging is also extremely difficult, often requiring professional disassembly and cleaning, resulting in a poor user experience. Second, arranging this piping system requires reserving complex wiring space inside the oven, increasing the complexity of the structural design and the amount of internal space occupied. Furthermore, after long-term use, limescale adhering to the inner walls of the pipes and nozzles is difficult to completely remove, posing a hygiene risk. Utility Model Content

[0003] This invention provides a steam oven that aims to solve the problems of existing technologies that use thin water pipes and tiny nozzles to supply steam, which easily lead to scale buildup, difficulty in cleaning, and complex structures.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A steam oven, comprising:

[0006] An oven body, the oven body including a lower shell, the bottom of the lower shell being provided with a mounting part;

[0007] A steam generator is provided at the mounting part. The steam generator includes a first water box and a heating pipe located in the first water box. A water storage chamber is formed in the first water box. The heating pipe is used to heat the water in the water storage chamber to generate steam.

[0008] A frying drum is disposed within the oven body and located above the first water tank; the frying drum is provided with a cooking cavity; and,

[0009] A steam guide channel is provided between the side wall of the frying bucket and the side wall of the oven body and is used to guide the steam generated by the steam generator into the cooking cavity of the frying bucket.

[0010] A further embodiment: the mounting part is a recessed groove formed by the downward indentation of the bottom wall of the lower housing, and the first water box is detachably disposed in the recessed groove of the lower housing.

[0011] Based on the above technical solution: the recessed design of the lower shell allows the first water box to be embedded in the bottom of the oven body, optimizing space utilization and making the overall structure more compact. At the same time, the first water box is detachably mounted in the recessed lower shell, making it convenient for users to remove it for cleaning.

[0012] A further solution: The first water box is provided with a heating tube mounting groove, and both sides of the heating tube mounting groove are provided to protrude upward from the bottom wall of the first water box;

[0013] The heating tube is located in the heating tube mounting slot, and the heating tube mounting slot is connected to an area inside the water storage cavity and located outside the heating tube mounting slot through at least one water inlet slot.

[0014] Based on the above technical solution: by setting up a heating pipe mounting slot and a water inlet slot, the raised heating pipe mounting slot forms a relatively independent heating area with less water storage within the first water box. This allows the heating pipe to quickly heat the small amount of water stored in this area, thereby rapidly generating initial steam and improving steam generation efficiency. Simultaneously, water from outside the heating pipe mounting slot can be slowly replenished into it through the water inlet slot.

[0015] A further option: the water inlet tank is configured in a bent or curved shape.

[0016] Based on the above technical solution: the bent or curved design allows the water flow from the external area to the heating pipe installation groove to be relatively slow, so that the water can be fully preheated during the flow in the water inlet groove, and then be quickly heated to generate steam after entering the heating pipe installation groove, which is beneficial to improving the thermal energy utilization efficiency.

[0017] A further solution: There are two water inlet tanks, which are respectively set on opposite sides of the heating pipe mounting slot.

[0018] A further embodiment: the heating element can be flipped upwards and installed inside the first water box.

[0019] Based on the above technical solution, users can easily clean the first water box by flipping the heating element upwards out of it.

[0020] A further solution: The first water box is provided with at least one handle.

[0021] Based on the above technical solution: the handle makes it convenient for users to pick up and put in the first water box, thereby facilitating the overall cleaning and water replacement of the first water box.

[0022] A further embodiment: The oven body is further provided with an upper shell, which is located above the frying drum, and the upper shell is provided with a guide part for guiding the steam in the air guide channel from the upper end of the frying drum to the cooking cavity.

[0023] Based on the above technical solution: the aforementioned setup utilizes the relatively large space between the frying drum and the oven body as a steam flow channel, fundamentally eliminating the risk of blockage due to scale buildup. Steam is generated at the bottom and rises naturally along this wide channel, then guided by the guide unit before entering the cooking cavity from the top of the frying drum, ensuring smoother steam replenishment.

[0024] A further embodiment: The frying barrel is also equipped with a second water box and a baking tray. The second water box is located below the baking tray and is equipped with a drain valve or a steam outlet.

[0025] Based on the above technical solution: by setting a second water tank inside the frying drum and located below the baking tray, the heating element can heat the water in the second water tank to generate steam. The steam rises and replenishes the bottom of the food with moisture. The steam generated by the second water tank combines with the main steam flow entering from the top of the frying drum and generated by the first water tank at the bottom, which can more evenly coat the food, achieving more sufficient steam replenishment to both the top and bottom of the food, and improving the tender baking effect.

[0026] A further embodiment: A first channel is provided between the upper end of the second water box and the baking tray; a second channel is provided between the side wall of the water box and the side wall of the frying bucket; a bottom receiving cavity is provided between the bottom wall of the water box and the bottom wall of the frying bucket; the bottom receiving cavity is connected to the second channel; and the second channel is connected to the first channel.

[0027] Based on the above technical solution: the first channel, the second channel, and the bottom receiving cavity form a steam flow path. Water in the second water tank first enters the bottom receiving cavity and is heated into steam. The steam then replenishes the food's moisture through the second and first channels. Furthermore, the design of the second channel allows oil dripping from the food during cooking to be guided downwards along the second channel between the baking pan and the second water tank, ultimately flowing into the bottom receiving cavity and concentrating, preventing oil from adhering to the side walls or the water tank. The oil accumulated at the bottom is continuously softened by the steam within the cavity during cooking, making subsequent cleaning easier and significantly improving the user experience.

[0028] The beneficial effects of this utility model are as follows:

[0029] This invention integrates the first water tank and heating element into the bottom of the oven body, and utilizes the wide gap between the frying drum and the side wall of the oven body as a steam channel. This allows the steam generated by the heating element heating the water in the first water tank to rise directly through the spacious channel and enter the cooking cavity from the top of the frying drum. This invention creatively provides a steam supply method that does not rely on thin water pipes and tiny nozzles, thus avoiding the problem of limescale clogging the nozzles and steam pipes, and greatly simplifying cleaning and maintenance.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0038] like Figures 1 to 4 As shown, this embodiment provides a steam oven, including:

[0039] Oven body 1, the oven body 1 includes a lower shell 12, the bottom of the lower shell 12 is provided with a mounting part;

[0040] A steam generator 3 is provided at the mounting part. The steam generator 3 includes a first water box 31 and a heating pipe 32 located in the first water box 31. A water storage cavity is formed in the first water box 31. The heating pipe 32 is used to heat the water in the water storage cavity to generate steam.

[0041] A frying tub 2 is disposed inside the oven body 1 and located above the first water tank 31; the frying tub 2 has a cooking cavity; specifically, a drawer-type frying tub 2 can be used; and,

[0042] A steam guide channel is provided between the side wall of the frying tub 2 and the side wall of the oven body 1 and is used to guide the steam generated by the steam generator 3 into the cooking cavity of the frying tub 2.

[0043] In this embodiment, as Figures 2 to 4 As shown, to optimize space utilization, the mounting portion is a recessed groove 121 formed by the downward indentation of the bottom wall of the lower housing 12, and the first water box 31 is detachably disposed within the recessed groove 121. The side walls and bottom wall of the recessed groove 121 are preferably integrally formed with the bottom wall of the lower housing 12.

[0044] The lower housing 12 has a protrusion 14 on its bottom wall surrounding the upper edge of the groove 121. The lower end of the frying bucket 2 abuts against the protrusion 14. This facilitates placing the frying bucket 2 inside or removing it from the oven body 1. The air guide channel 13 includes a rear channel between the rear side wall of the frying bucket 2 and the rear side wall of the oven body 1, a left channel between the left side wall of the frying bucket 2 and the left side wall of the oven body 1, and a right channel between the right side wall of the frying bucket 2 and the right side wall of the oven body 1. The lower end of the rear channel communicates with the rear side of the groove 121. The left and right channels are both connected to the rear channel, and the upper ends of the left, right, and rear channels communicate with the cooking cavity.

[0045] In this embodiment, as Figures 2 to 4As shown, to facilitate the installation of the heating tube 32, the first water box 31 is provided with a heating tube mounting groove 311. Both sides of the heating tube mounting groove 311 are raised upward from the bottom wall of the first water box 31. The heating tube 32 is located in the heating tube mounting groove 311. The raised heating tube mounting groove 311 forms a relatively independent heating chamber with a small water storage in the first water box 31, so that the heating tube 32 can quickly heat the small amount of water stored in the chamber, thereby quickly generating initial steam.

[0046] To allow water from outside the heating pipe mounting slot 311 to enter and replenish it, the heating pipe mounting slot 311 is connected to an area inside the water storage chamber located outside the heating pipe mounting slot 311 via at least one water inlet slot 312. Water replenished into the heating pipe mounting slot 311 via the meandering water inlet slot 312 is preheated and then rapidly heated into steam upon entering the heating pipe mounting slot 311. The water inlet slot 312 is bendable or curved. Specifically, it can be designed as a multi-folded line, a U-shape, an S-shape, a Z-shape, etc. Furthermore, the diameter of the water inlet slot 312 can be designed to be relatively narrow, allowing for a slower water flow.

[0047] Preferably, there are two water inlet tanks 312, which are respectively arranged on opposite sides of the heating pipe mounting groove 311.

[0048] In this embodiment, as Figures 2 to 4 As shown, to facilitate cleaning of the first water tank 31, the heating tube 32 is rotatably mounted inside the first water tank 31. Specifically, the two terminals of the heating tube 32 are rotatably connected to the lower housing 12. When the user needs to clean or remove the first water tank 31, the user can rotate the heating tube 32 upwards out of the first water tank 31, for example, by rotating it 90 degrees, thus facilitating cleaning. The main body of the heating tube 32 is shaped to be lower than the two terminals, making it easy to store the main body of the heating tube 32 into the heating tube mounting slot 311.

[0049] To facilitate user access to the first water tank 31, at least one handle is provided on the first water tank 31. Preferably, there are two handles, located on the left and right sides of the first water tank 31 respectively.

[0050] In this embodiment, the oven body 1 is further provided with an upper shell 11, which is located above the frying drum 2. The upper shell 11 is provided with a guide part 111 for guiding the steam in the air guide channel 13 from the upper end of the frying drum 2 to the cooking cavity. Specifically, the upper end of the upper shell 11 is recessed downward to form a concave portion, and the guide part 111 is specifically the outer wall surrounding the concave portion.

[0051] In this embodiment, as Figure 2 As shown, to achieve better steam replenishment of food, the frying drum 2 is also equipped with a second water box 21 and a baking tray 22. The second water box 21 is located below the baking tray 22, and a drain valve or steam outlet is provided on the second water box 21. Preferably, a drain valve is provided, specifically a drain valve of the prior art. The frying drum 2 is also equipped with a retaining part. When the second water box 21 is placed in the frying drum 2, the retaining part abuts against the valve core of the drain valve, thereby driving the drain valve to open, so that the water in the second water box 21 flows to the bottom of the frying drum 2, is heated by the heating tube 32 to generate steam, and the steam rises to replenish the bottom of the food. The steam generated by the second water box 21 combines with the main steam flow that enters from the top of the frying drum 2 and is generated by the first water box 31 at the bottom, which can more evenly coat the food, achieving more sufficient steam replenishment of the food on both the top and bottom sides, and improving the tender baking effect.

[0052] In this embodiment, as Figure 2 As shown, a first channel 23 is provided between the upper end of the second water box 21 and the baking tray 22; a second channel 24 is provided between the side wall of the water box and the side wall of the frying bucket 2; and a bottom receiving cavity 25 is provided between the bottom wall of the water box and the bottom wall of the frying bucket 2. The bottom receiving cavity 25 communicates with the second channel 24, and the second channel 24 communicates with the first channel 23. Specifically, the water in the second water box 21 first enters the bottom receiving cavity 25 and is heated into steam. Then, the steam replenishes the food with water through the second channel 24 and the first channel 23. Furthermore, the design of the second channel 24 allows oil dripping from the food during cooking to be guided downwards along the second channel 24 between the baking tray 22 and the second water box 21, eventually flowing into the bottom receiving cavity 25 and concentrating, thus preventing oil from adhering to the side wall or the water box.

[0053] Working principle explanation:

[0054] In use, the user can remove the first water box 31 via the handle, add an appropriate amount of water to the water storage chamber of the first water box 31, and then put it back into the groove 121 of the lower shell. Water can also be added to the second water box 21 at the same time. When the oven is started for steam roasting, the heating element 32 operates, heating the water in the first water box 31 to generate steam. The steam overflows and rises naturally along the steam guide channel between the frying bucket 2 and the oven body, entering the cooking chamber from the top of the frying bucket 2 to replenish the steam on the baking tray 22. Simultaneously, the heat in the cooking chamber also heats the second water box 21 to generate steam, which diffuses upwards through the second channel 24 and the first channel 23. The combined steam from above and below ensures more even heating and humidification of the food. Oil dripping during cooking will flow along the first channel 23 and the second channel 24 under gravity to collect in the bottom receiving cavity 25. After cooking, users can easily remove the second water tank 21 and baking tray 22 for cleaning. When the frying bucket 2 is removed and the heating tube 32 is flipped upwards, the inside of the first water tank 31 can be thoroughly cleaned and descaled. The walls of the steam guide channel are also easy to wipe after the frying bucket 2 is removed.

[0055] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
