Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to a humidifying dual-fan oven. Background Technology

[0002] As people's living standards improve, electric ovens, as kitchen appliances that use radiant heat from electric heating elements to bake food, are widely loved by consumers because they can quickly heat food to create a crispy crust while maintaining sufficient nutrients.

[0003] However, during the baking process, the high temperature of a traditional oven evaporates the moisture inside the food, resulting in poor taste and reduced nutritional value. In particular, if the baking temperature and time are not well controlled, the surface of the food can easily be burnt, which not only affects the visual appearance but also makes the food too dry, seriously affecting the taste.

[0004] To address this issue, most ovens on the market have steam generators installed on the outside of the oven, which spray water vapor generated by the steam generator into the oven through nozzles to humidify the food being baked; however, this often results in uneven humidification and difficulty in controlling the amount of humidification. Utility Model Content

[0005] Therefore, it is necessary to address the problems of uneven humidification and difficulty in controlling the amount of humidification when humidifying baked foods in most ovens on the market. This application provides a humidifying dual-fan oven, which can accurately control the amount of humidification while uniformly humidifying baked foods, thereby improving baking quality and food taste.

[0006] In one embodiment of this application, the present invention provides a humidifying dual-fan oven, comprising:

[0007] Inner liner;

[0008] The fan heating assembly includes two convection fans spaced apart on the rear wall of the inner liner and two back heating pipes spaced apart inside the inner liner and corresponding one-to-one with the convection fans;

[0009] An evaporation chamber is disposed within the inner liner and between the two back heating tubes; and

[0010] A water supply component is located outside the inner tank and connected to the evaporator piping for metering water supply to the evaporator.

[0011] According to one embodiment of this application, the back heating tube is fixed to the rear wall of the inner liner, and the back heating tube is arranged around the impeller of the convection fan.

[0012] According to one embodiment of this application, two convection fans are arranged at intervals along the vertical direction on the rear wall of the inner liner; two back heating pipes are arranged at intervals along the vertical direction on the rear wall of the inner liner.

[0013] According to one embodiment of this application, the fan heating assembly further includes an upper heating pipe disposed on the top wall of the inner liner and a lower heating pipe disposed on the bottom wall of the inner liner.

[0014] According to one embodiment of this application, the upper heating tube is located inside the inner liner; the lower heating tube is located outside the inner liner.

[0015] According to one embodiment of this application, the evaporation box includes a box body fixed to the rear wall of the inner liner and having a top opening, and a cover body covering the box body to close the top opening; the cover body has a plurality of vent holes arranged at intervals.

[0016] According to one embodiment of this application, the evaporation box extends along the left-right direction on the rear wall of the inner liner, and a plurality of the vent holes are arranged in an array along the left-right direction on the cover.

[0017] According to one embodiment of this application, the cover also has a water inlet spaced apart from the vent hole and communicating with the water supply assembly; the water inlet is located in the end region of the cover.

[0018] According to one embodiment of this application, the water supply assembly includes a water tank, a water pump connected to the water tank and the evaporator box via pipeline, and a solenoid valve disposed in the pipeline between the water tank and the water pump.

[0019] According to one embodiment of this application, the humidifying dual-fan oven further includes a control board disposed outside the inner cavity, the control board being communicatively connected to the fan heating assembly and the water supply assembly.

[0020] In summary, when the humidifying dual-fan oven starts its humidifying baking mode, the convection fans and back heating tubes in the fan heating assembly are activated first to evenly heat the inner cavity. At this time, the evaporator box located between the two back heating tubes is also heated to a high temperature. Then, the water supply assembly is activated to supply water to the evaporator box in a metered manner. At this time, the evaporator box, due to its high temperature and large contact surface with water, will generate a large amount of water vapor in the initial stage of water supply, which is discharged between the two convection fans. Then, under the action of the two convection fans, it is directly blown onto the surface of the food inside the inner cavity. The air inside the inner cavity is circulated by the wind force of the dual fans, so that the water vapor fills the entire space inside the inner cavity more quickly and evenly, so as to evenly humidify the baked food.

[0021] Furthermore, unlike traditional ovens that directly supply water vapor into the oven cavity, the humidifying dual-fan oven of this application first supplies liquid water to the evaporation box located inside the inner cavity, and then heats and evaporates it in the evaporation box. This allows for precise control of the humidification amount by controlling the amount of water supplied to the evaporation box, avoiding problems such as food being too wet or too dry due to inaccurate humidification control. This is of great significance for improving the taste of food. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] Traditional ovens, while equipped with external steam generators that spray steam into the oven to humidify the food being baked, often suffer from uneven humidification and difficulty in controlling the amount of moisture. Therefore, this application provides a humidifying dual-fan oven that can evenly humidify the baked food while precisely controlling the amount of moisture, thereby improving baking quality and enhancing the taste of the food.

[0034] Specifically, see the attached document. Figure 1 and Figure 2As shown, one embodiment of this application provides a humidifying dual-fan oven, which may include an inner cavity 10, a fan heating assembly 20, an evaporator box 30, and a water supply assembly 40. The fan heating assembly 20 includes two convection fans 21 spaced apart on the rear wall of the inner cavity 10 and two back heating pipes 22 spaced apart within the inner cavity 10 and corresponding one-to-one with the convection fans 21. The evaporator box 30 is disposed within the inner cavity 10 and located between the two back heating pipes 22. The water supply assembly 40 is disposed outside the inner cavity 10 and connected to the evaporator box 30 via piping, for metering water supply to the evaporator box 30. It is understood that the humidifying dual-fan oven of this application may also include a door assembly (not shown in the figure) covering the inner cavity 10 or other components that assist in achieving the baking function; these will not be elaborated upon further in this application.

[0035] More specifically, when the humidifying dual-fan oven starts the humidifying baking mode, the convection fan 21 and the back heating tube 22 in the fan heating assembly 20 are first activated to evenly heat the inner cavity 10. At this time, the evaporation box 30 located between the two back heating tubes 22 is also heated to a high temperature. Then, the water supply assembly 40 is activated to supply water to the evaporation box 30 in a metered manner. At this time, the evaporation box 30 generates a large amount of water vapor in the initial stage of water supply due to its high temperature and large contact surface with water. This water vapor is discharged between the two convection fans 21 and then blown directly onto the food surface inside the inner cavity 10 under the action of the two convection fans 21. The air inside the inner cavity 10 is circulated by the wind force of the dual fans, so that the water vapor fills the entire space inside the inner cavity 10 more quickly and evenly, so as to evenly humidify the baked food.

[0036] It is worth noting that, unlike traditional ovens that directly supply steam into the oven cavity, the humidifying dual-fan oven of this application first supplies liquid water to the evaporation box 30 located within the inner cavity 10, and then the water is heated and evaporated within the evaporation box 30. This allows for precise control of the humidification level by controlling the amount of water supplied to the evaporation box 30, avoiding problems such as food being too wet or too dry due to inaccurate humidification control. This is extremely important for improving the taste of food. Understandably, the amount of steam supplied directly into the oven cavity by traditional ovens is difficult to measure accurately, making it difficult to control the amount of steam supplied. This can easily lead to food being too wet or too dry due to excessive or insufficient steam supply.

[0037] For example, such as Figure 1 and Figure 2 As shown, the back heating tube 22 is fixed to the rear wall of the inner liner 10, and the back heating tube 22 is arranged around the impeller of the convection fan 21, so that the air driven by the convection fan 21 first flows through the back heating tube 22 to be heated, and then blows onto the food surface inside the inner liner 10 for baking.

[0038] Optionally, such as Figure 1 and Figure 2 As shown, two convection fans 21 are arranged at intervals along the vertical direction on the rear wall of the inner liner 10; similarly, two back heating pipes 22 are arranged at intervals along the vertical direction on the rear wall of the inner liner 10.

[0039] Optionally, such as Figure 3 and Figure 4 As shown, the evaporation box 30 includes a box body 31 fixed to the rear wall of the inner liner 10 and having a top opening 310, and a cover 32 covering the box body 31 to close the top opening 310. The cover 32 has a plurality of vent holes 321 arranged at intervals. In this way, the liquid water flowing into the box body 31 evaporates rapidly under the high temperature of the box body 31 to form a large amount of water vapor. The water vapor formed will first be discharged upward through the vent holes 321 to the back heating tube 22 for reheating to further increase the temperature of the water vapor, and then blown onto the surface of the food by the convection fan 21 to better humidify and bake the food.

[0040] Optionally, such as Figure 4 As shown, the evaporation box 30 extends along the left-right direction on the rear wall of the inner liner 10, and a plurality of vent holes 321 are arranged in an array along the left-right direction on the cover 32, so that the plurality of vent holes 321 are dispersed as much as possible on the rear wall of the inner liner 10, which helps to uniformly vent steam.

[0041] Optionally, such as Figure 4 As shown, the cover 32 further has a water inlet 322 that is spaced apart from the vent 321 and communicates with the water supply assembly 40, so that liquid water supplied by the water supply assembly 40 flows in from the top of the box 31 through the water inlet 322, ensuring that the liquid water supplied by the water supply assembly 40 can be quickly and completely added into the box 31, which is beneficial for quickly generating a large amount of water vapor.

[0042] Optionally, such as Figure 4 As shown, the water inlet 322 is located in the end region of the cover 32 so that the water supply assembly 40 and the water pipe connected to the water inlet 322 are arranged at the corner of the inner tank 10 to avoid structural interference with the convection fan 21 and the back heating pipe 22.

[0043] Optionally, such as Figure 2 As shown, the fan heating assembly 20 also includes an upper heating pipe 23 disposed on the top wall of the inner liner 10 and a lower heating pipe 24 disposed on the bottom wall of the inner liner 10, for heating the air inside the inner liner 10 from the upper and lower parts of the inner liner 10 respectively, which helps to heat the air inside the cavity more evenly and improve the food baking efficiency.

[0044] Optionally, such as Figure 2 As shown, the upper heating element 23 is located inside the inner liner 10, and the lower heating element 24 is located outside the inner liner 10. This allows the upper heating element 23, located inside the inner liner 10, to heat the air inside the cavity more efficiently; while the lower heating element 24, located outside the inner liner 10, ensures that the bottom wall of the inner liner 10 remains smooth while heating the air inside the cavity by heating the bottom wall of the inner liner 10, thus avoiding interference with cleaning the bottom wall of the inner liner 10. It is understood that food residue from baking usually falls and accumulates on the bottom wall of the inner liner 10; placing the lower heating element 24 inside the inner liner 10 would severely hinder residue removal.

[0045] According to the above embodiments of this application, as Figure 1 As shown, the water supply assembly 40 may include a water tank 41, a water pump 42 connected to the water tank 41 and the evaporation box 30 via pipeline, and a solenoid valve 43 disposed in the pipeline between the water tank 41 and the water pump 42, so as to precisely control the water supply to the evaporation box 30 by controlling the opening and closing of the solenoid valve 43, thereby precisely controlling the humidification amount.

[0046] Optionally, such as Figure 1 As shown, the humidifying dual-fan oven also includes a control board 50 disposed outside the inner cavity 10. The control board 50 is communicatively connected to the fan heating assembly 20 and the water supply assembly 40 for program control of the fan heating assembly 20 and the water supply assembly 40 to humidify and bake food.

[0047] For example, the control board 50 is electrically connected to the convection fan 21, the back heating pipe 22, the upper heating pipe 23, the lower heating pipe 24, the water pump 42, and the solenoid valve 43 to control the start and stop of the convection fan 21, the heating power of the back heating pipe 22, the heating power of the upper heating pipe 23, the heating power of the lower heating pipe 24, the start and stop of the water pump 42, and the opening and closing of the solenoid valve 43 according to a preset program.

[0048] 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.

[0049] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
