Description

Technical Field

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

[0002] Existing ovens primarily use electric heating elements or hot air circulation to bake food at high temperatures, employing a single heating method that relies solely on the conduction of heat through dry, hot air. While this cooking method can achieve the desired doneness, the lack of moisture replenishment leads to rapid evaporation of surface moisture and loss of internal juices, resulting in a dry, hard texture and tough, dry meat, severely impacting the eating experience. Especially when roasting meats, poultry, or baking bread, traditional ovens struggle to balance the need for a crispy exterior with a juicy interior. Users often need to resort to additional steps, such as wrapping the food in aluminum foil or spraying water mid-cooking, to improve the results. This process is not only cumbersome but also results in inconsistent control over the moisture content of the cooked food. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that existing ovens, with their single high-temperature baking method, result in food lacking moisture and having a dry, hard texture, thus affecting the eating experience. The invention provides a steam oven with a steam humidification function.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A steam oven includes a body, a steam generating module, a fan unit, and a heating module. The body has an airflow heating chamber and a cooking chamber arranged adjacent to each other on the inner side, and the airflow heating chamber and the cooking chamber are connected by an airflow inlet. The steam generating module includes a furnace body and a steam generator. The furnace body has an inner furnace cavity and a water inlet pipe connected to the furnace cavity at the bottom. A steam outlet is provided on one side of the upper part of the furnace body. The steam generator is located at the bottom of the furnace cavity, and the steam outlet is connected to the airflow heating chamber. The fan unit includes an impeller and a motor that drives the impeller. The impeller is located in the airflow heating chamber and is arranged corresponding to the airflow inlet. The heating module includes at least one heating element arranged around the outer periphery of the impeller for heating the gas in the airflow heating chamber. The fan unit is used to mix the steam generated by the steam generating module and the heated gas to form a heated airflow that is delivered to the cooking chamber.

[0006] Compared to existing technologies, this steam oven, through the coordinated operation of the steam generation module and the heating module, continuously replenishes an appropriate amount of steam during the baking process. This effectively prevents excessive evaporation of moisture from the food surface, keeping the interior juicy and flavorful. This results in crispy skin and tender, juicy interiors for roasted meats and poultry, significantly improving the taste and quality of the food and solving the problem of dry, hard, and tough food found in traditional ovens. The steam generation module, with its independent oven cavity and steam outlet design, can quickly generate stable steam, which is then evenly mixed with hot air by a fan and delivered to the cooking chamber, avoiding humidity fluctuations and ensuring consistent cooking results. Through structural optimization and system integration, this steam oven perfectly integrates steam moisturizing functions while retaining the efficient heating characteristics of traditional ovens, providing users with a simple, energy-efficient, and high-quality steam oven.

[0007] Furthermore, it also includes a partition baffle installed inside the machine body, which divides the inside of the machine body into the airflow heating chamber and the cooking chamber. The airflow inlet is located on the partition baffle, and the partition baffle is also provided with airflow circulation holes that connect the airflow heating chamber and the cooking chamber respectively. Several heating elements are provided, and the heating elements are heating tubes arranged in a ring. The end of the heating element is provided with a first electrical terminal. With this arrangement, the heating elements are arranged around the outer periphery of the impeller, and the connecting structure of the airflow heating chamber, the cooking chamber and the airflow circulation holes forms a hot air circulation. The steam and hot air mixed airflow flows efficiently under the drive of the fan, which significantly improves the heat utilization rate, shortens the cooking time and reduces energy consumption.

[0008] Furthermore, the steam generating module includes a flow guiding structure located within the furnace cavity. This flow guiding structure comprises a partition plate and a guide plate. The partition plate divides the furnace cavity into a lower steam generating chamber and an upper steam discharge chamber. The steam outlet is located within the steam discharge chamber. The guide plate is vertically connected to one end of the partition plate, forming a flow guiding channel between the guide plate and the furnace cavity sidewall. This allows the steam generated in the steam generating chamber to flow through both the flow guiding channel and the steam discharge chamber before exiting through the steam outlet. This configuration, through the flow guiding structure, achieves efficient steam generation and directional steam delivery. The partition plate divides the furnace cavity into the steam generating chamber and the steam discharge chamber, allowing the steam to be generated at the bottom and naturally rise to the steam discharge chamber, preventing insufficiently vaporized water droplets from directly entering the cooking chamber and ensuring uniform steam drying. Additionally, the flow guiding channel formed by the guide plate and the furnace cavity sidewall guides the steam along a specific path, reducing turbulence and heat loss, and improving steam delivery efficiency. Moreover, the steam needs to flow through the guide channel and steam exhaust chamber before being discharged. During this process, residual water droplets can fall back into the steam generation chamber due to gravity, and only dry steam is discharged from the outlet, avoiding excessive humidity or condensation in the cooking chamber and making the surface moisture of the food more uniform.

[0009] Furthermore, the bottom of the machine body is equipped with a water inlet solenoid valve connected to a water source, and the water inlet solenoid valve is connected to a water inlet pipe. The bottom of the furnace body is also equipped with a drain solenoid valve, which is connected to an external drain pipe. A water level probe is installed inside the furnace body. By setting the water level probe, the amount of water in the furnace cavity can be monitored and controlled in real time, and the water inlet solenoid valve can be triggered in time to replenish the water source, thus avoiding dry burning and damage to the steam generator.

[0010] Furthermore, the heating module includes heating elements located at the bottom of several furnace cavities. Each heating element is a multi-section bent heating tube, and each heating element is provided with a second electrical terminal located on the outside of the furnace body. With this arrangement, multiple heating elements are provided, ensuring sufficient steam generation from the steam generating module.

[0011] Furthermore, the machine body has a first component mounting area located outside the airflow heating chamber and the cooking chamber. A connecting bracket is provided on the outside of the steam generating module, allowing the steam generating module to be detachably mounted within the first component mounting area via the connecting bracket. This design allows manufacturers to select and install a steam generating module according to user needs, thus meeting specific usage requirements.

[0012] Furthermore, the first component mounting area is equipped with several cooling fans; with this arrangement, the cooling fans can cool down the circuits and electrical components in the first component mounting area, preventing high temperatures from damaging the circuits and electrical components.

[0013] Furthermore, a water collection inlet is provided at the bottom of the cooking chamber, and the machine body also has a second component installation area located below the airflow heating chamber and the cooking chamber. The second component installation area has a water receiving trough connected to the water collection inlet, and the water receiving trough is equipped with a drain connector connected to an external drain pipe. The first component installation area has an exhaust pipe connected to the water receiving trough, and the exhaust pipe extends out of the top of the machine body. With this arrangement, the water receiving trough can collect the condensed liquid water in the cooking chamber to avoid water accumulation. In addition, the exhaust pipe can stabilize the air pressure in the cooking chamber and prevent users from being injured by high-pressure steam when opening the steam oven.

[0014] Furthermore, the machine body is provided with a food inlet with a side opening, and the food inlet is equipped with a door for opening or closing the steam oven; a water collection trough is provided below the food inlet, the length of the water collection trough is adapted to the width of the food inlet, and the water collection trough is provided with a water outlet pipe connected to an external drain pipe; with this configuration, the water collection trough can collect the condensate water near the oven door in the cooking chamber, preventing the condensate water from spilling onto the platform when the oven door is opened.

At the bottom of 24, the steam outlet 23 is connected to the airflow heating chamber 11; the fan device 3 includes an impeller 31 and a motor 32 that drives the impeller 31 to rotate. The impeller 31 is located in the airflow heating chamber 11 and is correspondingly arranged with the airflow inlet 142; the heating module includes at least one heating element 4 arranged around the outer periphery of the impeller 31 for heating the gas in the airflow heating chamber 11; the fan device 3 is used to mix the steam generated by the steam generating module 2 and the heated gas to form a heated airflow that is delivered to one side of the cooking chamber 12.

[0026] Compared with existing technologies, this steam oven, through the coordinated operation of the steam generating module 2 and the heating module, continuously replenishes an appropriate amount of steam during the baking process, effectively preventing excessive evaporation of moisture from the food surface and maintaining its internal juiciness. This results in roasted meats and poultry with crispy skin and tender, juicy interiors, significantly improving the taste and quality of the food and solving the problem of dry, hard, and tough food in traditional ovens. The steam generating module 2, with its independent oven cavity 24 and steam outlet 23, can quickly generate stable steam, which is then evenly mixed with hot air by the fan device 3 and delivered to the cooking chamber 12, avoiding humidity fluctuations and ensuring consistent cooking results. Through structural optimization and system integration, this steam oven perfectly integrates steam moisturizing functions while retaining the efficient heating characteristics of traditional ovens, providing users with a steam oven that is easy to operate, energy-efficient, and produces excellent cooking results.

[0027] See Figures 2 to 5 In one embodiment, the system further includes a partition baffle 14 disposed within the body 1, which divides the inner side of the body 1 into the airflow heating chamber 11 and the cooking chamber 12.

With this arrangement, the efficient generation and directional delivery of steam are achieved by setting the flow guiding structure. The partition plate 25 divides the furnace cavity 24 into the steam generating chamber 27 and the steam exhaust chamber 28, so that the steam is generated in a concentrated manner at the bottom and naturally rises to the steam exhaust chamber 28, avoiding the direct entry of insufficiently vaporized water droplets into the cooking chamber 12, and ensuring uniform steam drying. In addition, the guide channel 261 formed by the baffle 26 and the side wall of the furnace cavity 24 guides the steam to flow along a specific path, reducing turbulence and heat loss, and improving steam delivery efficiency. Moreover, before being discharged, the steam must flow through the guide channel 261 and the steam discharge chamber 28.
