Description

Technical Field

[0001] This utility model relates to the field of cooking appliance technology, and in particular to a convection component and cooking device that combines microwave leakage prevention with hot air convection. Background Technology

[0002] Microwave ovens, steam ovens, and ovens are widely used in kitchens, but equipping a kitchen with these appliances is not only expensive but also requires sufficient kitchen space. To address this, a microwave-steam-oven combo has emerged, combining the functions of a microwave, steam oven, and oven while offering advantages such as small footprint and low production cost.

[0003] In existing microwave-steam-oven combination appliances, to ensure even heating of food within the inner cavity, a fan blade is typically installed inside the cavity to drive hot air convection. A convection motor is located outside the cavity, and its output shaft passes through the originally sealed cavity and connects to the fan blade to drive its rotation. When microwaves are used to heat food inside the cavity, microwaves can easily leak out through the gap between the cavity and the convection motor's output shaft, potentially harming human health.

[0004] To achieve microwave shielding, some manufacturers install a shielding cover inside the inner liner, which is then placed around the fan blades and welded to the inner wall of the liner. This prevents microwaves from leaking into the motor output shaft at the connection point between the shielding cover and the inner wall of the liner. The shielding cover has several air inlets on its windward side and several air outlets on its exhaust side, with the diameter of both the inlets and outlets being less than or equal to 5mm. This design effectively prevents microwaves from leaking into the motor output shaft through the air inlets and outlets.

[0005] However, when the above-mentioned shielding cover is used, although it can achieve a good microwave shielding effect, the small diameter of the air inlet and outlet holes on the shielding cover restricts the flow of gas, resulting in poor hot air convection and uneven heat distribution inside the inner pot, which in turn affects the cooking effect of food. Utility Model Content

[0006] To overcome at least one of the defects described in the prior art, this utility model provides a convection component that combines microwave leakage prevention with hot air convection. By limiting the diameter of the air inlet and outlet of the shielding cover to a range greater than 5 mm and less than or equal to 8 mm, it can not only shield most microwaves but also ensure the smooth flow of gas inside the inner liner, thereby ensuring its hot air convection effect. In addition, by setting a sealing component at the through hole of the motor mounting plate, when a small amount of microwaves enters the output shaft of the convection motor through the air inlet and outlet, it can be blocked by the sealing component, thereby preventing microwave leakage.

[0007] In addition, this utility model also provides a cooking device with the convection component, which has good hot air convection and microwave shielding effects.

[0023] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] Example 1 Combination Figures 1 to 5As shown, this utility model provides a convection assembly 1 that combines microwave leakage prevention with hot air convection, including an inner plate 11, a fan blade 12, a motor mounting plate 13, and a convection motor 15. The inner plate is configured as part of the inner liner 2, and can be one of the top plate, bottom plate, left and right side plates, or rear plate of the inner liner 2. The fan blade 12 is disposed on one side of the inner plate 11 and located inside the inner liner 2. The motor mounting plate 13 is disposed on the other side of the inner plate 11 and located outside the inner liner 2. The motor mounting plate 13 has a through hole 131, and a sealing assembly 14 for shielding microwaves is provided at the through hole 131. The convection motor 15 is mounted on the motor mounting plate 13. The output shaft 151 of the convection motor 15 passes through the sealing assembly 14 and is connected to the fan blade 12 for driving the fan blade 12 to rotate.

[0027] In addition, it also includes a shielding cover 16, which is located inside the inner liner 2 and covers the outer periphery of the fan blade 12; the shielding cover 16 includes an end face 161 and a side face 162 surrounding the outer edge of the end face 161. The end face 161 is provided with a plurality of air inlets 1611 to form a windward surface, and the side face 162 is provided with a plurality of air outlets 1621 to form an air outlet surface; wherein the diameter of the air inlets 1611 and the air outlets 1621 is greater than 5 mm and less than or equal to 8 mm.

[0028] Therefore, when the convection motor 15 is started, the gas inside the inner liner 2 can enter the shield 16 through several air inlets 1611, and then flow out of the shield 16 through several air outlets 1621, thereby realizing hot air convection inside the inner liner 2.

[0029] Therefore, by limiting the diameter of the air inlet 1611 and air outlet 1621 of the shielding cover 16 to a range greater than 5 mm and less than or equal to 8 mm, it can not only shield most microwaves, but also ensure the smooth flow of gas inside the inner liner 2, thereby ensuring its hot air convection effect. In addition, by setting the sealing component 14 at the through hole 131 of the motor mounting plate 13, when a small amount of microwaves enters the output shaft 151 of the convection motor 15 through the air inlet 1611 and air outlet 1621 on the shielding cover 16, it can be shielded by the sealing component 14, thereby preventing microwave leakage inside the inner liner 2.

[0030] Combination Figure 4 As shown, the shielding cover 16 is a cylindrical structure with one end open. Preferably, the end face 161 and the side face 162 of the shielding cover 16 are integrally formed by stamping or extrusion. This not only saves time and effort in processing and improves processing efficiency, but also eliminates the need for assembly and welding of the integrally formed shielding cover 16, thus preventing the phenomenon of desoldering or incomplete welding caused by welding, thereby reducing the risk of microwave leakage and improving the quality of the parts.

[0031] Of course, in other embodiments, the end face 161 and the side face 162 of the shield 16 can also be set separately, and the two can be connected into one piece by riveting or welding, which is not limited here.

[0032] More specifically, the bottom of the side 162 of the shield 16 is bent outward to form an outward flange 163, and the inner plate 11 has an opening 111 through which the fan blade 12 can pass. The shield 16 is hung on the opening 111 of the inner plate 11 by the outward flange 163. Preferably, the outward flange 163 is welded and fixed to the outer surface of the inner plate 11 at the opening 111.

[0033] Therefore, the shielding cover 16 is welded and fixed to the opening 111 of the inner plate 11 by the outer flange 163, so that microwaves will not leak from the connection between the shielding cover 16 and the inner wall of the inner liner 2, thereby achieving microwave shielding.

[0034] Furthermore, the outer flange 163 of the shield 16 is bent outward to form a mounting groove 164, in which the motor mounting plate 13 is installed. Thus, by creating the mounting groove 164 on the shield 16, when the fan blade 12 needs maintenance or replacement, the motor mounting plate 13 can be directly removed from the shield 16, allowing the convection motor 15 and fan blade 12 to be removed as a whole, making the operation more convenient.

[0035] Combination Figure 3 and Figure 5 As shown, the mounting groove 164 is also equipped with a sealing ring 171 and a copper coil 172. The sealing ring 171 abuts against the inner wall of the mounting groove 164 and the inner surface of the motor mounting plate 13 to form a seal, thereby preventing steam leakage from the inner liner 2. By setting the copper coil 172, when electromagnetic waves encounter the copper coil 172, due to the good conductivity of copper, an induced current will be generated on the surface of the copper coil 172. This induced current will generate a magnetic field opposite to the original electromagnetic wave, thereby canceling or weakening the propagation of the original electromagnetic wave, thus achieving a microwave shielding effect. Therefore, by setting the sealing ring 171 and the copper coil 172, while realizing the convection of hot air, it can prevent microwave leakage from the connection between the shielding cover 16 and the motor mounting plate 13 in the inner liner 2, and at the same time ensure the steam seal in the inner liner 2.

[0036] Combination Figure 3 as well as Figure 5As shown, the convection motor 15 includes a motor body 153, a convection bracket 152 fixedly connected to the motor body 153, and an output shaft 151 disposed on the motor body 153. The convection motor 15 is mounted on the motor mounting plate 13 via the convection bracket 152. The sealing assembly 14 includes a metal sleeve 141 connected to the through hole 131 of the motor mounting plate 13. The output shaft 151 of the convection motor 15 passes through the metal sleeve 141 and is connected to the fan blade 12. The output shaft 151 of the convection motor 15 has a clearance fit with the metal sleeve 141. The bottom end face of the metal sleeve 141 abuts against the convection bracket 152 to form a metal sealing area for shielding microwaves.

[0037] Specifically, the top of the metal sleeve 141 is fixed to the through hole 131 of the motor mounting plate 13 by a flange riveting process to achieve a seal. The convection bracket 152 is also provided with a groove 1521. The metal sleeve 141 extends into the groove 1521 and the bottom end face of the metal sleeve 141 abuts against the inner wall of the groove 1521 to achieve a seal. Thus, a metal sealing area can be formed inside the metal sleeve 141, thereby preventing microwaves from leaking out through the output shaft 151 of the convection motor 15.

[0038] Furthermore, the sealing assembly 14 also includes a sealing sleeve 142 fitted onto the convection bracket 152. The top surface of the sealing sleeve 142 is provided with a first elastic sealing edge 1421, which abuts against the outer surface of the motor mounting plate 13 to form a steam seal. The inner side of the sealing sleeve 142 is provided with a second elastic sealing edge 1422, which abuts against the outer wall of the metal sleeve 141 to form a steam seal.

[0039] Therefore, the General Motors provides a sealing component 14 at the through hole 131 of the motor mounting plate 13, which can prevent microwave leakage from the inner liner 2 between the through hole 131 of the motor mounting plate 13 and the output shaft 151 of the convection motor 15 while realizing the convection of hot air, and at the same time ensure the steam seal inside the inner liner 2.

[0040] Combination Figures 1 to 3 As shown, it also includes an inner heat insulation plate 18 located inside the inner liner 2. An inner heat insulation cavity is formed between the inner plate 11 and the inner heat insulation plate 18. The fan blade 12 and the shield 16 are both disposed in the inner heat insulation cavity. An air intake 181 is provided in the middle of the inner heat insulation plate 18, and an air blowing port 182 is provided around its periphery. When the convection motor 15 drives the fan blade 12 to rotate, the gas in the inner liner 2 flows sequentially through the air intake 181 of the inner heat insulation plate 18, several air inlets 1611 on the end face 161 of the shield 16, several air outlets 1621 on the side face 162 of the shield 16, and the air blowing ports 182 of the inner heat insulation plate 18 to form hot air convection.

[0041] Additionally, it includes a heating element 19 disposed within the inner insulation cavity, which surrounds the outer periphery of the side 162 of the shielding cover 16. Thus, the heating element 19 can reheat the gas within the inner insulation cavity, and the heated gas flows back into the inner liner 2 to heat the food, thereby improving the cooking efficiency.

[0042] In this embodiment, the air intake 181 is composed of multiple air intake holes, and the air outlet 182 is composed of multiple air outlet holes.

[0043] Example 2 Combination Figures 6 to 7 As shown, this utility model also provides a cooking device, including the convection component 1 of the above embodiment and the inner pot 2. The inner pot 2 is composed of an upper inner plate 21, a lower inner plate 22, a left inner plate 23, a right inner plate 24 and a rear inner plate spliced ​​together, and the inner plate 11 is one of the upper inner plate 21, the lower inner plate 22, the left inner plate 23, the right inner plate 24 and the rear inner plate.

[0044] Specifically, the upper inner plate 21, lower inner plate 22, left inner plate 23, and right inner plate 24 are integrally formed to form a rectangular frame with openings at both ends, and the rear inner plate is connected to the rear opening of the rectangular frame. In this embodiment, the inner plate 11 in the convection assembly 1 is the rear inner plate. Thus, when the convection motor 15 drives the fan blade 12 to rotate, the gas in the inner liner 2 can enter the inner insulation cavity through the air intake 181 of the inner insulation plate 18, then enter the shielding cover 16, and after being diffused to the surroundings by the fan blade 12, it flows out through several air outlets 1621 on the shielding cover 16. Then it is heated by the heating tube 19 and diffused to various positions inside the inner liner 2 through the air outlet 182 of the inner insulation plate 18. Furthermore, the cooking device in this application is specifically a microwave steam oven, which also includes a water tank and a steam generator installed on the inner liner 2. The steam generator is connected to the interior of the inner liner 2 to deliver high-temperature steam into the inner liner 2 during operation, thereby cooking the food inside the inner liner 2 and realizing a separate steaming function. In addition, it also includes a heating element placed on the inner liner 2, which can directly heat the food inside the inner liner 2 to realize a separate baking function. Furthermore, it includes a microwave generator placed on the inner liner 2 to generate microwaves and introduce them into the inner liner 2 to heat the food, thereby realizing a separate microwave function. Of course, the above-mentioned microwave, steaming and / or heating functions can also be combined together, for example, the heating element and the steam generator can be combined, or the heating element and the microwave function can be combined, or the heating element, microwave and steam can be combined, all of which are feasible and not limited in this application.

[0045] In summary, the convection component 1 and cooking device provided by this utility model, which combine microwave leakage prevention and hot air convection, have the following technical effects: (i) The convection component 1 of this utility model, by limiting the diameter of the air inlet 1611 and the air outlet 1621 of the shielding cover 16 to a range of greater than 5 mm and less than or equal to 8 mm, can not only shield most microwaves, but also ensure the smooth flow of gas inside the inner liner 2, thereby ensuring its hot air convection effect; in addition, by setting the sealing component 14 at the through hole 131 of the motor mounting plate 13, when a small amount of microwaves enters the output shaft 151 of the convection motor 15 through the air inlet 1611 and the air outlet 1621, it can be shielded by the sealing component 14, thereby preventing microwave leakage inside the inner liner 2.

[0046] (ii) The convection assembly 1 of this utility model is connected to a metal sleeve 141 at the through hole 131 of the motor mounting plate 13. The bottom end face of the metal sleeve 141 abuts against the convection bracket 152 of the convection motor 15 to form a metal sealing area for shielding microwaves. In addition, a sealing sleeve 142 is fitted on the convection bracket 152 of the convection motor 15. The first elastic sealing edge 1421 on the end face of the sealing sleeve 142 abuts against the motor mounting plate 13 to achieve a seal, and the second elastic sealing edge 1422 on the inner side of the sealing sleeve 142 abuts against the outer wall of the metal sleeve 141 to achieve a seal, thereby preventing steam leakage in the inner liner 2.

[0047] (III) The convection component 1 of this utility model, by setting a copper coil 172 in the mounting groove 164 of the shielding cover 16, when the electromagnetic wave encounters the copper coil 172, due to the good conductivity of copper, an induced current will be generated on the surface of the copper coil 172. This induced current will generate a magnetic field opposite to the original electromagnetic wave, thereby canceling or weakening the propagation of the original electromagnetic wave, thereby achieving the shielding effect; by setting a sealing ring 171 in the mounting groove 164, the sealing ring 171 can abut against the motor mounting plate 13 to achieve a seal, thereby preventing the leakage of steam in the inner tank.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
