Description

Technical Field

[0001] This application relates to the field of kitchenware technology, and in particular to cooking equipment. Background Technology

[0002] In cooking appliances with baking functions (such as ovens, steam ovens, combination steam ovens, and combination microwave-steam-oven appliances), the heating element and the hot air blower are the two core components. The heating element is the heat source of the cooking appliance, responsible for converting electrical energy into heat energy. The appliance uses the heat generated by the heating element to bake food. The hot air blower quickly from near the heating element onto the food, breaking up the unevenness of natural convection and preventing localized overheating or uneven cooking. Because the hot air blower helps improve the flow of hot air, heat can be transferred to the surface of the food more quickly, thus shortening baking time and improving baking efficiency.

[0003] However, in traditional cooking appliances with baking functions, there is usually only one hot air blower. This results in a single flow path for hot air inside the inner pot, which can easily lead to cold spots inside the inner pot. This is not conducive to the even distribution of heat generated by the heating element inside the inner pot, and it is not conducive to improving the baking effect of the cooking appliance. Utility Model Content

[0004] Therefore, it is necessary to provide a cooking device to address the above problems.

[0005] To address the above problems, this application provides the following technical solution:

[0006] A cooking device comprising:

[0007] Box;

[0008] The inner liner is fixedly installed in the box body;

[0009] A heating element is located in the inner liner;

[0010] A first drive motor includes a first base and a first output shaft, the first base being connected to the housing, and the first output shaft being rotatably connected to the first base; and

[0011] A hot air blower includes fan blades and a rotating part. The rotating part is connected to a first output shaft to rotate under the drive of the first output shaft. The fan blades are fixed to the rotating part and located inside the inner liner. Multiple hot air blowers are provided. The fan blades of all the hot air blowers are evenly distributed inside the inner liner and face the same direction. Furthermore, the rotating parts of all the hot air blowers are connected to the same first output shaft to rotate under the drive of the same first output shaft.

[0012] This cooking equipment has at least the following beneficial effects:

[0013] In this cooking equipment, multiple hot air blowers, driven by the same primary drive motor, create multidirectional airflow within the inner liner. This helps prevent cold zones within the liner and ensures even heat distribution from the heating elements, thus improving the baking effect. Furthermore, the even distribution and symmetrical orientation of the fan blades within the inner liner further enhances the even distribution of heat, contributing to improved baking performance.

[0014] In one embodiment, the cooking device further includes a belt, the rotating part being a pulley, the belt being tightly fitted onto the first output shaft and the rotating part of all the hot air blowers.

[0015] With this configuration, even if the first drive motor and the hot air blower are far apart, the output shaft can still drive the rotating part to rotate, which makes it convenient to arrange the drive motor and the hot air blower.

[0016] In one embodiment, the belt is a V-belt, each of the rotating parts is provided with a wheel groove, the wheel groove of each of the rotating parts is adapted to the belt, and the belt is tightly fitted around the wheel grooves of all the rotating parts.

[0017] This design increases the friction between the belt and the rotating part, which helps improve the transmission efficiency between the first output shaft and the rotating part. Furthermore, the belt is less prone to misalignment, ensuring stable transmission between the first output shaft and the rotating part.

[0018] In one embodiment, the cooking device further includes a second drive motor and a mounting plate. The second drive motor includes a second base and a second output shaft. The second base is fixed to the housing, and the second output shaft is rotatably connected to the second base. The mounting plate is fixed to the second output shaft. The first base is fixed to the mounting plate, and all rotating parts of the hot air blower are rotatably connected to the mounting plate.

[0019] With this configuration, each hot air blower revolves around the axis of the second output shaft under its drive. This helps to create multi-directional airflow within the inner liner, prevents cold zones from forming inside the liner, ensures that the heat generated by the heating element is evenly distributed within the liner, and improves the baking effect of the cooking equipment.

[0020] In one embodiment, all the fan blades of the hot air blower are evenly distributed around the axis of the second output shaft.

[0021] This design helps to distribute the heat generated by the heating element evenly within the inner cavity, thus improving the baking effect of the cooking equipment.

[0022] In one embodiment, all the fan blades of the hot air blower are evenly distributed around the axis of the second output shaft.

[0023] This design helps to distribute the heat generated by the heating element evenly within the inner cavity, thus improving the baking effect of the cooking equipment.

[0024] In one embodiment, the reference diameters of any two of the rotating parts are different.

[0025] This design allows each rotating part to operate at a different speed. On one hand, the varying speeds of the fan blades create a turbulent flow effect, which helps prevent cold spots within the inner liner and ensures even heat distribution within the liner, thus improving the baking effect of the cooking equipment. On the other hand, this avoids resonance that might occur when all the hot air blowers operate at the same frequency, reducing noise and mechanical wear, and extending the equipment's lifespan.

[0026] In one embodiment, the cooking device further includes a tensioning wheel rotatably connected to the mounting plate, and the tensioning wheel is provided in multiple manner; all the rotating parts of the hot air blower abut against the belt from one side of the belt, and the tensioning wheel and the first output shaft abut against the belt from the other side of the belt, so as to increase the wrap angle between each of the rotating parts and the belt.

[0027] This design helps prevent belt slippage and improves the transmission efficiency between the first output shaft and each rotating part.

[0028] In one embodiment, the heating tube surrounds a cylindrical space, and all the fan blades of the hot air blower are located within the cylindrical space.

[0029] This design allows the hot air to be evenly diffused from the center to the surroundings when all the fan blades of the hot air blower rotate, helps prevent cold spots from forming inside the inner liner, ensures that the heat generated by the heating element is evenly distributed inside the inner liner, and improves the baking effect of the cooking equipment.

[0030] In one embodiment, the axis of the cylindrical space coincides with the axis of the second output shaft.

[0031] This design allows the hot air to be evenly diffused from the center to the surroundings when all the fan blades of the hot air blower rotate, helps prevent cold spots from forming inside the inner liner, ensures that the heat generated by the heating element is evenly distributed inside the inner liner, and improves the baking effect of the cooking equipment.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] See Figures 1 to 5 This application provides a cooking device, which includes a housing 1, an inner liner 2, a heating element, a first drive motor 3, and a hot air blower 4. The inner liner 2 is fixed to the housing 1, and the heating element is disposed in the inner liner 2. The first drive motor 3 includes a first base 31 and a first output shaft 32. The first base 31 is connected to the housing 1, and the first output shaft 32 is rotatably connected to the first base 31. The hot air blower 4 includes fan blades 41 and a rotating part 42. The rotating part 42 is connected to the first output shaft 32 to rotate under the drive of the first output shaft 32. The fan blades 41 are fixed to the rotating part 42 and located inside the inner liner 2. Multiple hot air blowers 4 are provided. The fan blades 41 of all hot air blowers 4 are evenly distributed inside the inner liner 2 and face the same direction. Furthermore, the rotating parts 42 of all hot air blowers 4 are connected to the same first output shaft 32 to rotate under the drive of the same first output shaft 32.

[0046] In this cooking device, multiple hot air blowers 4, driven by the same first drive motor 3, form a multi-directional airflow within the inner liner 2. This helps prevent cold zones within the inner liner 2 and ensures that the heat generated by the heating element is evenly distributed within the inner liner 2, thereby improving the baking effect of the cooking device. Furthermore, the fan blades 41 of all the hot air blowers 4 are evenly distributed within the inner liner 2 and face the same direction, which also helps to evenly distribute the heat generated by the heating element within the inner liner 2, further enhancing the baking effect of the cooking device.

[0047] For example, the cooking appliance is an oven / steam oven / steam oven / microwave oven / steam oven.

[0048] See Figures 1 to 5 The cooking equipment also includes a belt 5, and the rotating part 42 is a pulley. The belt 5 is tightly fitted onto the first output shaft 32 and the rotating part 42 of all the hot air blowers 4. In this way, even if the first drive motor 3 and the hot air blowers 4 are far apart, the output shaft can still drive the rotating part 42 to rotate, which facilitates the arrangement of the drive motor and the hot air blowers 4.

[0049] See Figure 5 The belt 5 is a V-belt, and each rotating part 42 has a pulley groove 421. The pulley groove 421 of each rotating part 42 is conformally fitted to the belt 5, and the belt 5 is tightly fitted around all the pulley grooves 421 of the rotating parts 42. This increases the friction between the belt 5 and the rotating parts 42, which is beneficial to improving the transmission efficiency between the first output shaft 32 and the rotating parts 42. Furthermore, the belt 5 is less prone to deviation, which helps to ensure stable transmission between the first output shaft 32 and the rotating parts 42.

[0050] In some embodiments, the cooking device further includes a second drive motor and a mounting plate. The second drive motor includes a second base and a second output shaft. The second base is fixed to the housing 1, and the second output shaft is rotatably connected to the second base. The mounting plate is fixed to the second output shaft. A first base 31 is fixed to the mounting plate, and the rotating parts 42 of all the hot air blowers 4 are rotatably connected to the mounting plate. In this way, each hot air blower 4 will revolve around the axis of the second output shaft under its drive. This is beneficial for multiple hot air blowers 4 to form multidirectional airflow within the inner liner 2, which helps to prevent cold zones from appearing within the inner liner 2, and helps to evenly distribute the heat generated by the heating element within the inner liner 2, thereby improving the baking effect of the cooking device.

[0051] Preferably, all the fan blades 41 of the hot air blower 4 are evenly distributed around the axis of the second output shaft. This facilitates the even distribution of heat generated by the heating element within the inner liner 2, thereby improving the baking effect of the cooking equipment.

[0052] In some embodiments, all the fan blades 41 of the hot air blower 4 are evenly distributed around the axis of the second output shaft. This facilitates the even distribution of heat generated by the heating element within the inner liner 2, thereby improving the baking effect of the cooking equipment.

[0053] In other embodiments, the fan blades 41 of all the hot air blowers 4 may also be arranged in a square array.

[0054] See Figure 4 and Figure 5 The reference diameters of any two rotating parts 42 are different. This results in different rotational speeds for each rotating part 42. On one hand, the turbulent flow created by the fan blades 41 rotating at different speeds helps prevent cold zones within the inner liner 2 and ensures even heat distribution within the inner liner 2, thus improving the baking effect of the cooking equipment. On the other hand, this avoids resonance that might occur when all the hot air blowers 4 operate at the same frequency, reducing noise and mechanical wear, and extending the equipment's lifespan.

[0055] See Figure 2 , Figure 3 and Figure 5 The cooking equipment also includes a tensioning pulley 6, which is rotatably connected to the mounting plate. Multiple tensioning pulleys 6 are provided. All rotating parts 42 of the hot air blower 4 abut against the belt 5 from one side, while the tensioning pulleys 6 and the first output shaft 32 abut against the belt 5 from the other side, thereby increasing the wrap angle between each rotating part 42 and the belt 5. This helps prevent belt 5 slippage and improves the transmission efficiency between the first output shaft 32 and each rotating part 42.

[0056] Preferably, the heating element surrounds a cylindrical space, and all the fan blades 41 of the hot air blower 4 are located within this cylindrical space. This facilitates the even diffusion of hot air from the center to the surrounding areas when all the fan blades 41 of the hot air blower 4 rotate, helps prevent cold zones from appearing inside the inner liner 2, ensures that the heat generated by the heating element is evenly distributed within the inner liner 2, and improves the baking effect of the cooking equipment.

[0057] Preferably, the axis of the cylindrical space coincides with the axis of the second output shaft. This facilitates the even diffusion of hot air from the center to the surroundings when all the fan blades 41 of the hot air blower 4 rotate, helps prevent cold spots from appearing inside the inner liner 2, ensures that the heat generated by the heating element is evenly distributed inside the inner liner 2, and improves the baking effect of the cooking equipment.

[0058] In some embodiments, the heating element is located directly in front of all the hot air blowers 4.

[0059] 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.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the appended claims.
