Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically to a steam-infused oven. Background Technology

[0002] Ovens are baking equipment used in daily life for processing pasta. Some pasta products have higher requirements for oven baking, requiring steam to be introduced into the oven for auxiliary baking. The most common example is European-style bread. The steam injection in the oven is a special step in bread making. The steam helps to "gelatinize" the dough, resulting in a crispy texture in the finished product.

[0003] However, existing commercial food ovens rely on external steam generators to supply steam for bread processing. These external steam generators suffer from heat loss during steam delivery, require long steam production times and high power (generally over 2KW), resulting in high production costs and inconvenience. Therefore, we urgently need an oven that can generate its own steam internally, offering greater convenience and energy efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a steam-generating oven. This utility model solves the problems of long steaming time, high power consumption, and high manufacturing cost of existing commercial layer food ovens by setting up a high-frequency heating tube, water supply tube, conductive block, detachable fasteners and water receiving tray.

[0005] The technical solution adopted by this utility model to solve its technical problem is a steam-generating oven, which includes an oven body and a steam generator. The oven body is provided with an inner cavity and an oven door that closes the inner cavity. The steam generator is located in the upper part of the inner cavity. The inner cavity is also provided with a heating component and a support bracket.

[0006] The steam generator includes a housing and a cover that form an encapsulated whole. Multiple vent holes are provided on both sides of the housing. A high-frequency heating tube and a water supply pipe are provided inside the housing. A water receiving tray for receiving water output from the water supply pipe is also provided inside the housing. A detachable fastener is provided on the outside of the high-frequency heating tube to tightly connect the high-frequency heating tube and the water receiving tray. Multiple conductive blocks to improve heat conduction are also provided on the water receiving tray.

[0007] When the oven is working, the dough is placed on the corresponding dough tray, supported by a bracket. Baking is achieved through the heating elements within the cavity, aided by steam generated by a steam generator. Removable fasteners secure the high-frequency heating element to the drip tray, ensuring better heat transfer and optimal heating efficiency. The oven's own heating and the high-frequency heating element's heat transfer effectively accelerate the drip tray's heating time. When the drip tray reaches the preset temperature, water is sprayed onto it through a pipe on one side of the oven shell, generating steam within the cavity. This steam is then transported into the cavity through the vent. The high-frequency heating element enables rapid heating, facilitating steam generation and improving baking results. Because it utilizes the oven's own heat transfer, the high-frequency heating element only requires 1kW to produce a good amount of steam, achieving energy savings. Being built-in, no insulation is needed for the steam generator, further reducing costs.

[0008] Preferably, the housing is further provided with a temperature sensor that contacts the water receiving tray and detects the temperature of the water receiving tray.

[0009] When the high-frequency heating tube inside the shell heats the water tray, the temperature sensor outside the shell detects the temperature of the water tray in real time, so that when the predetermined temperature is reached, the water supply pipe can spray water into the water tray in time to generate steam.

[0010] Preferably, the housing is provided with a first fixing member for fixing the water pipe to the housing, and the housing is provided with a second fixing member for fixing the steam generator to the inner cavity.

[0011] The first fixing component positions the water supply pipe to prevent it from shifting and causing water to fail to fall into the receiving tray properly. The second fixing component is used to fix the steam generator to the inner cavity.

[0012] Preferably, the first and second fixing components are mounting flanges.

[0013] Preferably, the oven body is provided with a gas vent area communicating with the inner cavity, and the gas vent area is provided with multiple pressure relief holes.

[0014] The oven body is not a completely sealed environment, and there will be some gaps that allow excess steam to leak out. For pasta that requires a lot of steam to bake, in order to prevent the oven door from being forced open due to excessive steam, a venting area is set up to release the steam and pressure. This can remove excess steam in time and ensure that an appropriate amount of steam remains in the oven to assist in baking.

[0015] Preferably, the output end of the water supply pipe is connected to a nozzle.

[0016] By adjusting the nozzle settings, the water volume can be refined, resulting in faster steam generation.

[0017] Preferably, the heating assembly includes a first heating element disposed in the upper part of the inner cavity and a second heating element disposed in the lower part of the inner cavity.

[0018] Ovens with top and bottom heating elements heat up faster and produce more even baking results.

[0019] Preferably, the inner cavity is further provided with a support bar for mounting the two ends of the support bracket and enabling the support bracket to be pulled out.

[0020] The support frame is supported by support bars, allowing it to be pulled out and moved like a drawer.

[0021] Preferably, the detachable fastener is a fastening plate, and the fastening plate and the conductive block are fixed to the water receiving tray by screw connection, welding or pin connection.

[0022] The use of fastening plates allows for better contact with the outer surface of the high-frequency heating tube due to their deformable properties, making installation convenient and quick.

[0023] Preferably, the temperature sensor and the high-frequency heating element are electrically connected to the oven body.

[0024] Through the integrated circuit design of the oven body, the oven, temperature sensor, and high-frequency heating element are controlled by the same power supply to ensure normal and coordinated operation.

[0025] The beneficial effects of this utility model are:

[0026] This utility model discloses an internally generated steam oven. A detachable fastener secures the high-frequency heating element to the water tray, allowing for better heat transfer to the tray and achieving optimal heating efficiency. Through the oven's own heating and the high-frequency heating element's heat transfer within the steam generator, the water tray's heating time is effectively accelerated. When the tray reaches the predetermined temperature, water is sprayed onto it through a water pipe on one side of the casing, generating steam within the cavity. The steam is then transported into the cavity through the vent. The high-frequency heating element enables rapid heating, which is more conducive to steam generation and improves the baking effect of pasta. Because it utilizes the oven's own heat transfer, the high-frequency heating element only requires 1KW to generate a good amount of steam, achieving energy savings. As it is an internal design, no insulation treatment is needed for the steam generator, thus saving costs. Attached Figure Description

[0035] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0036] To improve energy efficiency and reduce costs, as one embodiment of this utility model, such as Figures 1-6 As shown, the present invention discloses a steam-generating oven, comprising an oven body 1 and a steam generator 2. The oven body 1 has an inner cavity 3 and an oven door 4 that seals the inner cavity 3. The steam generator 2 is located on the upper part of the inner cavity 3. The inner cavity 3 also includes a heating element 5 and a support bracket 6. The oven body 1 also includes a power control switch 7. The heating element 5 includes a first heating element 51 located on the upper part of the inner cavity 3 and a second heating element 52 located on the lower part of the inner cavity 3. The inner cavity 3 also includes support strips 8 for supporting both ends of the support bracket 6 and enabling the support bracket 6 to be pulled out. When baking pasta, the pasta can be placed on a pasta tray, and then the pasta tray can be placed on the support bracket 6. The support bracket 6 is supported by the support strips 8, allowing the support bracket 6 to be pulled out and moved like a drawer. By pushing, the support bracket 6 can be pushed back into the inner cavity 3 of the oven. The first heating element 51 and the first heating element 52 heat the oven from both above and below, resulting in a faster temperature increase and a more uniform baking effect. The first heating element 51 and the first heating element 52 can be implemented using any existing technology, such as an electric heating tube.

[0037] The steam required for baking is provided by the steam generator 2 located in the inner cavity.

[0038] The steam generator 2 includes a housing 9 and a cover 10 forming an encapsulated assembly. The housing 9 is used to house and fix corresponding components, and the cover 10 is used to seal the housing 9 and protect the components inside the housing 9. Multiple vent holes 11 are provided on both sides of the housing 9, through which the steam generated by the steam generator 2 is discharged into the inner cavity 3. A high-frequency heating tube 12 and a water supply pipe 13 are provided inside the housing 9. A water receiving tray 14 is also provided inside the housing 9 to receive the water output from the water supply pipe 13. A detachable fastener 15 is provided on the outside of the high-frequency heating tube 12 to tightly connect the high-frequency heating tube 12 to the water receiving tray 14. Multiple heat conduction blocks 16 are also provided on the water receiving tray 14 to further accelerate steam generation.

[0039] When the oven is working, baking is carried out by the heating element 5 in the inner cavity 3, and steam is generated by the steam generator 2 to assist baking. A removable fastener 15 presses the high-frequency heating element 12 tightly onto the water tray 14, allowing the temperature generated by the high-frequency heating element 12 to be better transferred to the water tray 14, achieving optimal heating transfer efficiency. Through the heating transfer of the oven itself and the high-frequency heating element 12 in the steam generator 2, the heating time of the water tray 14 is effectively accelerated. When the water tray 14 reaches the predetermined temperature, water is sprayed onto the water tray 14 by the water pipe 13 on one side of the shell 9, thereby generating steam in the inner cavity 3. The steam is transported to the inner cavity 3 through the exhaust port 11. The use of the high-frequency heating element 12 enables rapid heating, which is more conducive to steam generation and improves the baking effect of pasta. The conductive block 16 can be made of threaded steel. The function of the conductive block 16 is to increase the contact area with the water, allowing the water tray 14 to generate steam faster and better.

[0040] Because it utilizes the oven's own heat transfer, the high-frequency heating element 12 only requires 1KW to generate a good amount of steam, thus achieving energy savings. Since it is built-in, there is no need for insulation in the steam generator 2, thereby saving costs.

[0041] The housing 9 is also equipped with a temperature sensor 17 that contacts the water receiving tray 14 and detects its temperature. Since the high-frequency heating tube 12 heats the bottom of the water receiving tray 14, the temperature sensor 17 should contact the upper side of the water receiving tray 14 for more accurate temperature detection. When the high-frequency heating tube 12 inside the housing 9 heats the water receiving tray 14, the temperature sensor 17 outside the housing 9 detects the temperature of the water receiving tray 14 in real time. When the water receiving tray 14 reaches the predetermined temperature, the water supply pipe 13 can promptly spray water into the water receiving tray 14 to generate steam. It should be noted that the water supply pipe 13 sprays a small amount of water; if the water volume is too large, it will not be able to generate steam instantly. When the temperature of the water receiving tray 14 drops below the predetermined value, the water supply pipe 13 stops spraying water and waits for the water receiving tray 14 to heat up.

[0042] To address the issue of increased pressure caused by steam generated inside the oven, the oven body 1 is provided with an air vent 18 that connects to the inner cavity 3, and the air vent 18 is provided with multiple pressure relief holes 19.

[0043] The oven body 1 is not a completely sealed environment, and there will be some gaps where excess steam can leak out. Normal baking will not create a high-pressure environment. For pasta that requires a lot of steam to bake, in order to prevent the oven door 4 from being forced open by excessive steam, a venting zone 18 is set up to release pressure and remove excess steam in time, ensuring that an appropriate amount of steam remains in the oven to assist baking.

[0044] Regarding the issue of fixing the water pipe 13, the housing 9 is provided with a first fixing member 20 for fixing the water pipe 13 to the housing 9. The first fixing member 20 is used to position the water pipe 13 to prevent the water from falling into the water receiving tray 14 due to displacement of the water pipe 13.

[0045] Regarding the fixing of the steam generator 2, the housing 9 is provided with a second fixing member 21 for fixing the steam generator 2 to the inner cavity 3. The second fixing member 21 is used to fix the steam generator 2 to the inner cavity 3. The first fixing member 20 and the second fixing member 21 are mounting flanges.

[0046] The output end of the water supply pipe 13 is connected to a nozzle. The nozzle is used to refine the water and generate steam more quickly. The nozzle can be implemented using any existing technology, but it must be ensured that the water from the nozzle can only fall into the water receiving tray. The nozzle is not shown in the figure and will not be described in any further detail. It is only necessary to meet the requirements of the existing technology.

[0047] The detachable fastener 15 is a fastening plate. The fastening plate is designed to better fit the outer surface of the high-frequency heating tube 12 by utilizing its deformable properties, and it is also convenient and quick to install. The fastening plate and the conductive block 16 are fixed to the water receiving tray 14 by screws, welding, or pins.

[0048] The temperature sensor 17 and the high-frequency heating tube 12 are electrically connected to the oven body 1, and the heating component 5 is also electrically connected to the oven body 1. The oven body 1 can be equipped with a control center. Through the integrated circuit design of the oven body 1, the oven body 1, temperature sensor 17, high-frequency heating tube 12 and heating component 5 are controlled by the same power supply and control center to coordinate the normal operation of the oven body 1, temperature sensor 17, high-frequency heating tube 12 and heating component 5. The control center can be implemented using any existing technology, which will not be elaborated here.

[0049] Working principle:

[0050] Place the pasta in the baking pan, open the oven door 4, pull out the support bracket 6, place the pasta pan on the support bracket 6, push the support bracket 6 back in, and close the oven door 4. Turn on the oven; the heating element 5 starts working, baking the pasta evenly from top to bottom. Simultaneously, the steam generator 2 starts working, and the high-frequency heating element 12 drives the water tray 14 to heat up rapidly. The high-frequency heating element 12 transfers heat to the water tray 14 by being in close contact with it. Combined with the heating effect of the heating element 5 on the air in the cavity 3, this more energy-efficiently heats the water tray 14. Once the water tray 14 reaches the predetermined temperature, the water supply pipe 13 delivers an appropriate amount of water to the water tray 14 to generate steam. The steam is released into the cavity 3 through the vent 11 to assist in baking the pasta. When the steam volume is too large, some steam is discharged through the pressure relief hole 19 in the venting area 18 to maintain the air pressure and an appropriate amount of steam in the cavity 3.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
