Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to an air guide cover for a cooking utensil and a cooking utensil having the air guide cover. Background Art

[0002] Most of the high-end microwave ovens, microwave ovens, steam ovens and other products in daily use are of the pull-down door type, with the oven door pulled down, and the entire control system and electrical components are placed above the cavity. Since the size of the control box is limited and all electrical components are located here, it is difficult to dissipate heat. Therefore, a heat dissipation system is provided in the control box. Common heat dissipation systems include fan motors, fan blades, fan covers, air guide covers, etc. Among them, the air guide cover covers electrical components that are prone to heat (such as transformers, inverters, magnetrons, etc.), and the cooling fan and the air guide cover are fixed together by bolts, so that the cold intake air is blown into the air guide cover through the fan and flows in the air guide cover. When the cold air flows from the air guide cover, it takes away the heat, and finally blows out the heat through the gap between the control box and the oven door, thereby achieving heat dissipation of the electrical components inside the control box. As product functions become more and more complex, the number of electrical components inside the air duct is increasing, resulting in poor heat dissipation and higher maintenance frequency. In addition, the outside of the air duct is also equipped with a series of other components such as thermostats, light bulbs, computer boards, wiring harnesses, etc., so the air duct currently used has brought great difficulties to after-sales maintenance.

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation of the present invention.

[0036] Reference will be made below Figures 1 - 9 to describe the air guide hood 100 for a cooking appliance according to an embodiment of the first aspect of the present invention.

[0037] The air guide hood 100 for a cooking appliance according to an embodiment of the first aspect of the present invention, as Figure 1 shown, the air guide hood 100 includes: a windshield main body 10 and a cover body 20. The windshield main body 10 defines an electrical appliance accommodation space (such as the first space 11 and the second space 13 described below), the windshield main body 10 has an opening communicating with the electrical appliance accommodation space, and the electrical appliance components of the cooking appliance are adapted to be arranged inside the electrical appliance accommodation space; the cover body 20 is detachably connected to the windshield main body 10 to close the opening.

[0038] Specifically, the electrical appliance accommodating space is used to accommodate the electrical components of the cooking appliance that are prone to heat generation. The electrical appliance accommodating space can be designed according to the electrical components of the cooking appliance, increasing the applicability of the air guide cover 100. The cooling fan is fixedly connected to the hood body 10 to provide cold air cooling for the electrical components arranged in the electrical appliance accommodating space. The hood body 10 provides an air flow channel for the air flow, enabling the air flow to flow along the air flow channel, increasing the heat exchange rate and improving the heat exchange effect. The cover body 20 is used to close the opening of the hood body 10. The cover body 20 is configured according to the opening position and the electrical components arranged in the electrical appliance accommodating space. Different positions and different functions can be provided with different cover body 20 structures and connection forms, thereby increasing the adaptability of the air guide cover 100.

[0039] When the electrical components arranged in the electrical appliance accommodating space are damaged, the cover body 20 at the corresponding position can be disassembled, providing a disassembling space and conditions for the damaged electrical components. Then, the damaged electrical components can be disassembled, repaired, and restored in a targeted manner, reducing the time and difficulty of disassembly, repair, and restoration. After the electrical components are reinstalled to their original positions, the cover body 20 is fixedly connected to the hood body 10 again to complete the repair of the cooking appliance.

[0040] According to the air guide cover 100 for a cooking appliance according to an embodiment of the present invention, the detachable connection between the cover body 20 and the hood body 10 can improve the installation convenience and maintainability of the electrical components in the electrical appliance accommodating space.

[0041] According to some embodiments of the present invention, as Figure 1 shown, the cover body 20 is snap-connected to and / or connected to the hood body 10 through a fastener 16. Among them, the cover body 20 and the hood body 10 can be connected by snap connection, or can be connected by the fastener 16, or can also be connected by using a combination of snap connection and the fastener 16. The connection manner between the cover body 20 and the hood body 10 can be selected according to different connection positions. The snap connection and the connection by the fastener 16 both have relatively simple structures, low costs, and are convenient for installation and disassembly. Thereby, the production cost of the air guide cover 100 can be reduced, and the installation and disassembly convenience between the hood body 10 and the cover body 20 can be improved.

[0042] According to some embodiments of the present invention, as Figures 1 - 2As shown, the number of electrical appliance accommodation spaces, the number of openings, and the number of the cover bodies 20 are all multiple, and the multiple openings, the multiple electrical appliance accommodation spaces, and the multiple cover bodies 20 correspond to each other one by one. The number of electrical appliance accommodation spaces, the number of openings, and the number of the cover bodies 20 can be selected according to the number and positions of the electrical components of the cooking appliance. For example, they can be two, three or more. The cover body 20 is mainly used to close the opening, fix the electrical components in the accommodation space, and form a gas flow channel, so as to ensure the heat dissipation effect of the electrical components arranged in the accommodation space. At the same time, the cover body 20 is detachable, which increases the convenience of repairing the electrical components in the accommodation space.

[0043] According to some embodiments of the present invention, as Figure 2 shown, the multiple electrical appliance accommodation spaces include: the first space 11, and the multiple cover bodies 20 include the first cover body 21. Among them, one side of the first space 11 facing away from the cavity of the cooking appliance (for example Figure 2 the upper side of the first space 11 described in

[0044] According to some embodiments of the present invention, as Figure 2 shown, the wind hood main body 10 includes a bracket part 12, and the bracket part 12 is located on the side of the first space 11 facing the cavity. The frequency converter 200 of the cooking appliance is adapted to be fixed on the bracket part 12. Among them, the bracket part 12 is a plastic bracket. Since the voltage of the frequency converter 200 is very high, it cannot be directly in contact with metal parts, and the upper plate of the cavity is a metal part. Therefore, the frequency converter 200 is fixedly installed by using the bracket part 12 to isolate the frequency converter 200 from the upper plate of the cooking appliance cavity, so as to ensure the normal operation of the frequency converter 200. In addition, the bracket part 12 is arranged on the wind hood main body 10, which can increase the integration of components, and further increase the installation convenience.

[0045] For example Figures 2 - 4As shown, the support part 12 includes a bottom plate 124. A first protrusion 125 is formed along the perimeter of the bottom plate 124. On the side of the support part 12 facing the opening, there are a fixed connection column 121, a buckle 122, and a support plate 123. The fixed connection column 121 is provided on the bottom plate 124 and is located at the rear end of the support part 12. The buckle 122 is provided on the first protrusion 125. There are multiple buckles 122, which are respectively arranged at the front end and the rear end of the support part 12. On the central axis of the bottom plate 124 in the length direction, there is a first support plate 1231 extending left and right, and on the central axis of the bottom plate 124 in the width direction, there is a second support plate 1232 extending front and back. The first support plate 1231 is perpendicular to the second support plate 1232, forming a "cross" structure. On the first support plate 1231, there are a second protrusion 1233 and a first convex block 1234. The second protrusion 1233 is provided at the left end of the first support plate 1231. There are two first convex blocks 1234, which are formed on the left and right sides of the first support plate 1231 and are symmetrically arranged with respect to the second support plate 1232. The first convex block 1234 is a vertical plate extending front and back. The cross-section of the first convex block 1234 is square. The lower end of the first convex block 1234 is connected to the bottom plate 124, and the front end is connected to the first support plate 1231.

[0046] For example Figure 7 As shown, the frequency converter 200 has a bottom mounting plate for carrying the components of the frequency converter 200 and for fixedly installing with the support part 12. The mounting plate is provided with fixed mounting holes and positioning grooves, which respectively correspond one-to-one to the fixed connection column 121 and the second protrusion 1233 and the first convex block 1234. The fixed connection column 121 and the fixed mounting hole can be connected by bolts, which is convenient for disassembly. The inner surface of the first protrusion 125 abuts against the outer surface along the perimeter of the bottom mounting plate of the frequency converter 200. The first support plate 1231 and the second support plate 1232 provide a supporting effect for the frequency converter 200, so as to form a certain installation space between the frequency converter 200 and the bottom plate 124 of the support part 12, which is convenient for the installation of the wiring harness of the frequency converter 200 and the flow of air, and increases the installation aesthetics and heat dissipation of the frequency converter 200. The front and rear ends of the bottom mounting plate are fixed on the support part 12 through the buckle 122 to prevent the frequency converter 200 from moving up and down, and the installation stability between the frequency converter 200 and the support part 12 can be increased.

[0047] According to some embodiments of the present invention, such as Figure 2As shown, a plurality of first fixing holes 211 are formed on the first cover body 21. The plurality of first fixing holes 211 are arranged at intervals along the peripheral edge of the first cover body 21. A plurality of second fixing holes 14 are formed on the wind hood main body 10. The plurality of second fixing holes 14 correspond to the plurality of first fixing holes 211 one by one. The first cover body 21 is fixed to the wind hood main body 10 by a fastener 16 passing through the first fixing holes 211 and the second fixing holes 14. For example, the number of the first fixing holes 211 and the second fixing holes 14 can be two, three or more. Arranging the plurality of fixing holes at intervals along the peripheral edge can increase the installation stability of the first cover body 21 and the wind hood main body 10. At the same time, using the fastener 16 as a connecting member can increase the convenience of installation and disassembly of the first cover body 21 and the wind hood main body 10.

[0048] According to some embodiments of the present invention, as Figure 8 shown, the first cover body 21 is in the shape of a plate body recessed in the direction away from the cavity, so that a certain space can be formed at the upper end of the frequency converter 200, which is convenient for air flow, can effectively cool the frequency converter 200, and improve the cooling effect of the frequency converter 200.

[0049] Specifically, for example Figure 8 shown, the first cover body 21 includes a top plate 212, side plates 213, a front cover plate 214 and a rear cover plate 215. The top plate 212 extends forward and backward. The front end of the top plate 212 is connected to the front cover plate 214 extending forward and downward. The rear end of the top plate 212 is connected to the rear cover plate 215 extending backward and downward. There are two side plates 213, which are respectively connected to the left and right sides of the top plate 212 and extend downward. The upper ends of the side plates 213 are connected to the front cover plate 214, the top plate 212 and the rear cover plate 215.

[0050] According to some embodiments of the present invention, as Figure 2 shown, the plurality of electrical accommodation spaces include a second space 13, and the plurality of cover bodies 20 include a second cover body 22. Among them, the opening communicating with the second space 13 penetrates through one side edge of the wind hood main body 10 (for example Figure 2 the left side edge of the wind hood main body 10 described above), and the second cover body 22 is connected to the opening position of the second space 13. Among them, the opening communicating with the second space 13 penetrates through one side edge of the wind hood main body 10, so that electrical components with larger matching dimensions or partially protruding from the second space 13 can be accommodated in the second space 13. When the electrical components arranged inside the second space 13 are damaged and need to be repaired and replaced, first disassemble the second cover body 22 to make the opening position of the second space 13 in a through state, so that the internal electrical components are exposed, and then disassemble, repair and replace the electrical components. After the replacement is completed, fix the second cover body 22 back to the opening position of the second space 13 to complete the repair.

[0051] Furthermore, the second cover body 22 is used to fixedly place the electrical components in the second space 13, which can improve the installation stability of the electrical components.

[0052] According to some embodiments of the present invention, as Figure 9 shown, a hook 221 extending towards the air duct main body 10 is formed on the second cover body 22, and a slot 15 is formed on the air duct main body 10. The hook portion 2212 of the hook 221 is snapped into the slot 15. By using the structural mode of the hook 221 and the slot 15 to connect the second cover body 22 and the air duct main body 10, the convenience of fixing and disassembling the second cover body 22 can be improved, and the maintainability can be enhanced.

[0053] Furthermore, for example Figure 9 shown, the hook 221 includes a cantilever 2211 and a hook portion 2212. One end of the cantilever 2211 is connected to the second cover body 22, and the other end is connected to the hook portion 2212. The hook portion 2212 includes a first connecting arm, a second connecting arm, and a third connecting arm. The first connecting arm extends horizontally; the second connecting arm and the third connecting arm extend vertically; the left and right ends of the first connecting arm are respectively connected to the upper ends of the second connecting arm and the third connecting arm, and the lower end of the second connecting arm is fixedly connected to the cantilever 2211; the third connecting arm includes an angular region, and the third connecting arm is snap-fitted with the slot 15 on the air duct main body 10 through the angular region. In the direction from top to bottom, the width of the angular region gradually decreases, and in the direction from front to back, the width of the angular region gradually increases until it abuts against the inner wall of the slot 15 and then extends horizontally. By snap-fitting the angular region of the third connecting arm with the slot 15 of the air duct main body 10, the friction between the third connecting arm and the slot 15 can be reduced, making it easier for the third connecting arm to enter and exit the slot 15, thereby increasing the convenience of fixing and disassembling the second cover body 22 and enhancing the maintainability.

[0054] According to some embodiments of the present invention, as Figure 9 shown, the second cover body 22 is formed in a U-shaped frame shape, which has a simple structure, is convenient to manufacture, uses less materials, can reduce the production cost of the second cover body 22, and thus reduce the production cost of the entire air duct 100; in addition, the second cover body 22 is connected to the side wall of the air duct main body 10 and forms a through hole penetrating the side wall of the air duct main body 10, and thus can fix electrical components with larger sizes or electrical components partially protruding from the air duct main body 10, for example, a magnetron.

[0055] Specifically, for example Figure 9As shown, the second cover body 22 includes a first connecting plate 222 and two second connecting plates 223. The first connecting plate 222 extends forward and backward, and the second connecting plates 223 extend upward and downward. The two second connecting plates 223 are respectively connected to both ends of the first connecting plate 222. The upper end surfaces of the second connecting plates 223 are flush with the upper end surface of the first connecting plate 222, forming a U-shaped frame structure with an opening facing downward. The sizes of the first connecting plate 222 and the second connecting plates 223 match the opening position of the second space 13, and the outer surfaces of the second connecting plates 223 are flush with the outer surface of the wind hood main body 10.

[0056] According to some embodiments of the present invention, as Figure 2 shown, an air flow inlet and an air flow outlet are respectively formed at both ends of the electrical appliance accommodation space in the air flow direction, and the central axis of the opening is perpendicular to the central axis of the air flow inlet. Among them, the electrical appliance accommodation space forms an air flow passage, enabling the air flow to circulate in the entire accommodation space and be discharged from the cooking appliance, which can reduce the heat of the electrical appliances inside the accommodation cavity space, thereby ensuring the working safety of the cooking appliance. In addition, the opening is adjacent to the air flow inlet and is not in the same plane, which can not hinder the air flow, enabling the heat dissipation system of the cooking appliance to work properly.

[0057] Specifically, cold air enters the capacitor accommodation space from the air flow inlet, flows in the accommodation space, takes away the heat generated by the operation of the electrical appliances inside the accommodation space, and then is discharged from the air flow outlet.

[0058] For example Figure 2 shown, the air flow inlet is arranged at the rear end of the air guide hood 100, and the air flow direction is from back to front. The openings are respectively arranged on the upper side and the left side of the air guide hood 100, adjacent to the air flow inlet and perpendicular to the plane where the air flow inlet is located.

[0059] According to some embodiments of the present invention, as Figure 2 shown, the wind hood main body 10 is integrally formed and is a plastic part. Among them, the plastic part is inexpensive, and the wind hood main body 10 is an integrally formed part with a simple structure and convenient production, which can improve production efficiency and reduce production costs.

[0060] Furthermore, a plurality of lugs 17 are provided on the periphery of the wind hood main body 10, and connection holes are provided on the lugs 17. The wind hood main body 10 is fixedly connected to the upper plate of the cavity through the connection holes. The lugs 17 can increase the contact area with the upper plate of the cavity, thereby increasing the installation stability of the air guide hood 100.

[0061] The cooking utensil according to the second embodiment of the present invention comprises: a cavity and an air scoop 100 for the cooking utensil according to the first embodiment of the present invention, the air scoop 100 being arranged on one side surface of the cavity, and the air scoop 100 and the cavity cooperating to define a heat dissipation air duct. The air scoop 100 can be arranged on the upper side, the rear side, or one of the left and right sides of the cavity; the air scoop 100 and the cavity cooperating to define the heat dissipation air duct can limit the flow direction of the airflow, thereby increasing the heat dissipation effect of the cooking utensil; in addition, the cooking utensil can be a microwave oven, a microwave oven, or a steam oven.

[0062] According to the cooking appliance of the embodiment of the present invention, the overall performance of the cooking appliance is improved by providing the air guide cover 100 for the cooking appliance of the first embodiment.

[0063] The following will refer to Figures 1 - 9 A cooking appliance according to a specific embodiment of the present invention is described.

[0064] Reference Figures 1 - 2 The cooking appliance includes: a cavity, an air guide cover 100, a cooling fan and electrical components.

[0065] Among them, the air guide cover 100 is arranged on the upper side of the cavity, and the air guide cover 100 is fixedly connected to the upper plate of the cavity to define a heat dissipation duct; the heat dissipation fan is arranged at the rear end of the air guide cover 100 and is fixedly connected to the air guide cover 100 by bolts; the electrical components are arranged on the inner side of the air guide cover 100, and the electrical components include a frequency converter 200 and a magnetron.

[0066] Specifically, Figure 1 As shown, the air guide cover 100 includes an air cover body 10 and a cover body 20. The air cover body 10 is an integrally formed plastic part, and the cover body 20 is detachably connected to the air cover body 10.

[0067] The hood body 10 defines an electrical appliance accommodating space, and the electrical appliance components of the cooking utensil are suitable for being arranged inside the electrical appliance accommodating space. The electrical appliance accommodating space includes a plurality of electrical appliance accommodating spaces, including two detachable accommodating spaces, a first space 11 and a second space 13. Specifically, the hood body 10 is fixedly connected to the cooling fan; the front and rear ends of the first space 11 and the second space 13 are both open to form openings, which serve as airflow outlets and airflow inlets, so that cold air enters the air guide hood 100 from the rear end of the hood body 10 for air cooling, and then is discharged from the airflow outlet to complete heat dissipation. A bracket portion 12 is provided at the bottom of the first space 11 for fixing and installing the frequency converter 200 of the cooking utensil; the upper part of the first space 11 is open to form a first opening; the second space 13 is connected from top to bottom, and the left side is an open side, and a second opening is formed for arranging the magnetron.

[0068] The cover body 20 includes a first cover body 21 and a second cover body 22. The first cover body 21 is in the shape of a plate body that is recessed in the direction away from the cavity, and is connected to the first opening position of the first space 11 through bolts to close the first space 11. The second cover body 22 is formed in the shape of a U-shaped frame with an opening downward. A hook 221 facing the hood body 10 is formed at the upper end of the frame. A card slot 15 is formed on the hood body 10. The hook portion 2212 of the hook 221 is snapped into the card slot 15 to connect the second cover body 22 to the hood body 10 for fixing the magnetron.
