Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to an air fryer microwave oven. Background Technology

[0002] As living standards improve, cooking methods are becoming increasingly diverse, and single kitchen appliances can no longer meet consumer needs. Air fryer microwaves, which integrate the functions of an air fryer and a microwave oven, have a promising market prospect due to their ability to rapidly heat, defrost, and cook food using high-temperature air circulation and / or microwave radiation, while also occupying minimal space.

[0003] The applicant's research revealed that existing air fryer microwave ovens typically have a bottom plate. During cooking, heat from the heating cavity radiates to the bottom plate, causing it to overheat. The most severely heated areas are concentrated on the front side and the side furthest from the electrical cavity. Touching these areas not only affects the user experience but also poses a risk of burns.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The problem solved by this invention is that the bottom plate of existing air fryer microwave ovens has a high temperature, which poses a certain safety hazard.

[0006] To address the aforementioned problems, this utility model provides an air fryer microwave oven, including a cooking cavity for cooking food; a base plate is disposed below the bottom of the cooking cavity, and an electrical cavity is disposed on one side of the cooking cavity; the air fryer microwave oven further includes a first heat insulation component and / or a second heat insulation component to prevent the user from touching the base plate, the first heat insulation component being fixedly disposed on the side of the base plate away from the electrical cavity, and the second heat insulation component being fixedly disposed on the front side of the base plate. This design makes it difficult for the user to directly touch the hot base plate; at the same time, it provides visual obstruction of the bottom of the air fryer microwave oven, further improving its aesthetic appearance and providing a better user experience.

[0007] Preferably, the base plate has a reinforcing rib on the side away from the electrical cavity. The reinforcing rib extends in the front-to-back direction and protrudes towards the side away from the cooking cavity. A first mating hole is provided on the reinforcing rib. The first heat insulation member includes a first plate and a second plate connected together. A first mounting hole is provided on the first plate. The first mounting hole and the first mating hole are connected by screws. The second plate is vertically arranged to shield the side of the air fryer microwave oven. This arrangement can shield the side of the air fryer microwave oven with the second plate, reducing the gap between the side and the tabletop to prevent fingers or other objects from reaching through the gap and touching the base plate, thus ensuring high safety. At the same time, the reinforcing rib provides installation space for screws, preventing assembly screws from touching or even affecting the integrity of the cooking cavity.

[0008] Preferably, a mounting platform is provided on the rear side of the base plate for mounting the furnace feet; the second heat insulation component includes a baffle for shielding the base plate from the front, and the second heat insulation component also includes a frustum fixedly connected to the base plate, there are two frustums and they are connected to the baffle through a connecting plate, and the lowest point of the frustum is on the same horizontal plane as the lowest point of the furnace feet.

[0009] This design allows the second heat insulation component to be assembled using the existing oven foot fixing structure, while maintaining the same height as the oven foot to effectively support the air fryer microwave oven. The structure is simple and easy to manufacture.

[0010] Preferably, the connecting plate gradually tapers towards the frustum from the end near the baffle, and reinforcing ribs are provided on the connecting plate and / or the baffle. This arrangement allows for a smooth transition from the baffle to the frustum position, while also giving the second heat insulation component good mechanical strength and a long service life.

[0011] Preferably, the air fryer microwave oven further includes a door assembly, with an opening on the front side of the cooking cavity, and the door assembly can selectively seal the opening; the second heat insulation member is located below the door assembly, and the maximum horizontal distances between the second heat insulation member, the door assembly, and the cooking cavity and its rear sidewall are L1 and L2, respectively, where L1 < L2. This arrangement ensures that the second heat insulation member does not protrude outside the door assembly, resulting in an aesthetically pleasing overall appearance.

[0012] Preferably, the first and second heat insulation components are made of polymer plastic. This design prevents the high-temperature heat from the base plate from being conducted to the first and second heat insulation components; it has a simple structure, saves costs, and effectively improves the user experience.

[0013] Preferably, a hot air structure is provided at the upper part of the cooking cavity for circulating hot air into the cooking cavity; the hot air structure includes an upper heating element, the cooking cavity includes a top plate, and the upper heating element includes a first heating element and a second heating element, which are located on the upper and lower sides of the top plate, respectively. This arrangement can further improve the heating uniformity within the cooking cavity, shorten the cooking time, and improve the final cooking effect on the food; the structure is simple and easy to implement.

[0014] Preferably, a lower heating element is disposed above the bottom of the cooking cavity, and a lower cover plate is disposed above the lower heating element. The lower cover plate is made of borosilicate glass. This arrangement can further ensure that the temperature inside the cooking cavity is uniform and there is no significant temperature difference, resulting in good uniform heating of the food and a short cooking time. Borosilicate glass has a low coefficient of thermal expansion, which can maintain good stability when heated at high temperatures and is not prone to deformation or breakage.

[0015] Preferably, the hot air structure includes a cover and a partition. The cover and the top plate together form a hot air space, and the partition divides the hot air space into two relatively independent hot air chambers. A fan is provided in each of the two hot air chambers to deliver hot airflows in opposite directions to the cooking cavity from the two adjacent hot air chambers.

[0016] This configuration allows two hot air chambers to simultaneously deliver hot air into the cooking cavity, which improves the uniformity of hot air distribution within the cooking cavity, enhancing heating efficiency and speed. The two hot air chambers operate independently with opposite airflow directions, preventing airflow interference and resulting in better airflow performance.

[0017] Preferably, the housing includes a fixed plate and a heat insulation plate stacked together. The heat insulation plate is located on the side of the fixed plate near the top plate. The fan is located between the heat insulation plate and the top plate. The top plate and the hot air space are provided with a plurality of ventilation holes evenly distributed. The top plate is partially recessed to form a clearance portion for accommodating the fan.

[0018] This design reduces the upward conduction of heat generated by the upper heating element to the motor assembly, improving the operational stability and reliability of the motor assembly; at the same time, it increases the overall strength of the hot air structure and enhances the heat insulation effect, preventing the loss of internal heat.

[0019] Compared with the prior art, the air fryer microwave oven described in this utility model embodiment has the following beneficial effects: 1) The air fryer microwave oven can prevent users from directly touching the hot bottom plate, and at the same time, it shields the bottom, improving its appearance; 2) The second plate can shield the side of the air fryer microwave oven, reducing the gap between the side and the tabletop to prevent fingers from sticking in through the gap and touching the bottom plate, thus ensuring high safety; the reinforcing ribs provide installation space for screws, preventing assembly screws from touching or even affecting the integrity of the cooking cavity; 3) The structure is simple and easy to manufacture.

Detailed Implementation

[0028] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Without conflict, the technical features of the embodiments of this utility model can be combined with each other.

[0029] It should be noted that all directional and positional terms used in this utility model, such as "up," "down," "left," "right," "front," "back," "vertical," "horizontal," "inner," "outer," "top," "lower," "lateral," "longitudinal," and "center," are only used to explain the relative positional relationships and connections between components in a specific state (as shown in the accompanying drawings).

[0031] With technological advancements, air fryer microwave ovens are gaining popularity as a new type of cooking appliance. They combine microwave penetrating heating with radiant heating from heating elements, enabling rapid heating, defrosting, and cooking of food while occupying minimal space, thus possessing broad market prospects. However, during cooking, heat from the cooking cavity 1 radiates to the base plate 5, causing it to reach a relatively high temperature. If easily touched by customers, this could negatively impact their experience and even lead to burns. Therefore, the applicant proposes the following technical solution:

[0032] Example 1

[0033] like Figure 1-4 As shown, an air fryer microwave oven includes a cooking cavity 1 for cooking food; a base plate 5 is disposed below the bottom of the cooking cavity 1, and an electrical cavity is disposed on one side of the cooking cavity 1; the air fryer microwave oven also includes a first heat insulation member 6 and / or a second heat insulation member 7, the first heat insulation member 6 is fixedly disposed on the side of the base plate 5 away from the electrical cavity, and the second heat insulation member 7 is fixedly disposed on the front side of the base plate 5 to prevent the user from touching the base plate 5.

[0034] Because the heat radiation from the cooking cavity 1 causes the bottom plate 5 to be at a high temperature, the first heat insulation component 6 and the second heat insulation component 7 prevent the user from directly touching the hot bottom plate 5. At the same time, the first heat insulation component 6 and the second heat insulation component 7 can visually shield the bottom of the air fryer microwave oven, further improving its appearance and providing a better user experience.

[0035] As an example of this utility model, the base plate 5 is provided with a reinforcing rib 51 on the side away from the electrical cavity. The reinforcing rib 51 extends in the front-to-back direction and protrudes towards the side away from the cooking cavity 1. A first mating hole 511 is provided on the reinforcing rib 51. The first heat insulation member 6 includes a first plate and a second plate connected together. A first mounting hole 61 is provided on the first plate. The first mounting hole 61 and the first mating hole 511 are connected by screws. The second plate is vertically arranged on the side away from the electrical cavity from the first plate. This arrangement can use the second plate to shield the side of the air fryer microwave oven, reduce the gap between the side and the tabletop, and prevent fingers or other objects from sticking into the gap and touching the base plate 5, thus ensuring high safety.

[0036] As an example of this utility model, a mounting platform 52 is provided on the rear side of the base plate 5 for mounting the oven legs 8; the second heat insulation member 7 includes a connected baffle 73 for shielding the base plate 5 from the front. The second heat insulation member 7 also includes two frustums 71 fixedly connected to the base plate 5, which are connected to the baffle 73 by a connecting plate 72. The lowest point of the frustum 71 is on the same horizontal plane as the lowest point of the oven legs 8. This arrangement allows the second heat insulation member 7 to be assembled using the existing oven leg 8 fixing structure, while maintaining the same height as the oven legs 8 to effectively support the air fryer microwave oven. The structure is simple and easy to manufacture.

[0037] As a preferred example, the connecting plate 72 gradually tapers towards the frustum 71 from one end near the baffle 73, and reinforcing ribs are provided on the connecting plate 72 and / or the baffle 73. This arrangement allows the baffle 73 to smoothly transition towards the location of the frustum 71, while also giving the second heat insulation member 7 good mechanical strength and a long service life.

[0038] Preferably, the first heat insulation component 6 and the second heat insulation component 7 are made of polymer plastic. This design can prevent the high temperature heat from the base plate 5 from being conducted to the first heat insulation component 6 and the second heat insulation component 7; it has a simple structure, saves costs, and can effectively improve the user experience.

[0039] The air fryer microwave oven also includes a door assembly 10. An opening is provided on the front side of the cooking cavity 1, and the door assembly 10 can selectively seal the opening. A second heat insulation member 7 is located below the door assembly 10. The maximum distances between the second heat insulation member 7, the door assembly 10, and the cooking cavity and the rear sidewall of the cooking cavity 1 on the horizontal plane are L1 and L2, respectively, where L1 < L2. This arrangement ensures that the second heat insulation member 7 is located below the door assembly 10 without protruding from it, resulting in a superior user experience.

[0040] It should be noted that the air fryer microwave oven also includes a control panel 9, which is located on the front side of the electrical cavity and is on the same plane as the door assembly 10. Its specific structure is existing technology. The control panel 9 and the door assembly 10 together constitute the exterior surface of the air fryer microwave oven, resulting in an aesthetically pleasing overall appearance.

[0041] Example 2

[0042] Existing air fryer microwave ovens typically have a heating structure located above the top of the cooking cavity 1 for heating, which has drawbacks such as long cooking time and poor temperature uniformity within the cooking cavity 1. Therefore, the applicant has made the following improvements based on Embodiment 1:

[0043] like Figure 5-6 As shown, an air fryer microwave oven includes a cooking cavity 1 and a hot air structure 2. The hot air structure 2 is located at the upper part of the cooking cavity 1 and is used to circulate hot air into the cooking cavity 1. The hot air structure 2 includes an upper heating element 25, which includes a first heating element 251 located above the top of the cooking cavity 1; the upper heating element 25 also includes a second heating element 252 located below the top of the cooking cavity 1. This configuration can further improve the heating uniformity within the cooking cavity 1, shorten the cooking time, and improve the final cooking effect on the food; the structure is simple and easy to implement.

[0044] Preferably, the first heating element 251 consists of two straight heating tubes, and the second heating element 252 is a U-shaped heating wire. The second heating element 252 has protrusions on both sides parallel to the first heating element 251, with the protrusions converging towards each other at the center. This arrangement increases the heating length of the second heating element 252 and, in conjunction with the first heating element 251, enhances the heating uniformity within the cooking cavity 1, thus improving the food's cooking effect.

[0045] As an example of this utility model, the cooking cavity 1 includes a top plate 101, with the first heating element 251 and the second heating element 252 located on the upper and lower sides of the top plate 101, respectively. This arrangement exposes only the second heating element 252 inside the cooking cavity 1, effectively preventing oil fumes from contaminating the upper heating element 25; at the same time, the second heating element 252 directly generates heat radiation inside the cooking cavity 1, thereby reducing temperature fluctuations within the cooking cavity 1 and improving the final cooking effect of the food.

[0046] Preferably, a lower heating element 3 is disposed above the bottom of the cooking cavity 1, and a lower cover plate 4 is disposed above the lower heating element 3. The lower cover plate 4 is made of borosilicate glass. This arrangement can further ensure that the temperature inside the cooking cavity 1 is uniform and there is no significant temperature difference, the food is heated evenly and the cooking time is short, resulting in a better user experience. Borosilicate glass has a low coefficient of thermal expansion, which can maintain good stability when heated at high temperatures and is not prone to deformation or cracking. Its smooth surface is not easy to be stained with oil and food residue, making it easy to clean.

[0047] As an example of this utility model, the hot air structure 2 includes a cover and a partition 26. The cover is located above the top plate 101 and the two together form a hot air space. The partition 26 divides the hot air space into two relatively independent hot air chambers. The hot air structure 2 also includes a motor assembly 23 and a fan 24. The fan 24 is disposed in the hot air chamber. The drive shaft of the motor assembly 23 passes through the cover and is driven to connect with the fan 24, thereby delivering hot airflows with opposite rotation directions to the cooking cavity 1 from the two adjacent hot air chambers.

[0048] This configuration allows two hot air chambers to simultaneously deliver hot air into the cooking cavity 1, improving the uniformity of hot air distribution within the cooking cavity 1 and enhancing heating efficiency and speed. The two hot air chambers are independent of each other, and the hot airflow rotates in opposite directions, preventing mutual interference and resulting in better airflow. As an example of this invention, the motor assembly 23 includes a first motor and a second motor, which respectively drive the fans 24 in the two relatively independent hot air chambers to rotate.

[0049] Preferably, the housing includes a stacked fixing plate 21 and a heat insulation plate 22. The heat insulation plate 22 is located on the side of the fixing plate 21 near the top plate 101. The fan 24 is disposed between the heat insulation plate 22 and the top plate 101. The motor assembly 23 is fixed on the side of the fixing plate 21 away from the heat insulation plate 22. There is a gap between the mounting surface of the fixing plate 21 and the heat insulation plate 22. This arrangement can reduce the upward conduction of heat generated by the upper heating element 25 to the motor assembly 23, improving the operational stability and reliability of the motor assembly 23; at the same time, it can improve the overall strength of the hot air structure 2 and increase the heat insulation effect, preventing the loss of internal heat.

[0050] As an example of this utility model, a plurality of ventilation holes 1012 are evenly arranged at positions corresponding to the hot air space on the top plate 101, and a portion of the top plate 101 is recessed downward to form a clearance portion 1011 for accommodating the fan 24. This arrangement allows the hot air generated by the fan 24 to enter the cooking cavity 1 more smoothly, while reducing the overall height of the hot air structure 2, making the structure of the air fryer microwave oven more compact.

[0051] Preferably, the top plate 101 is provided with two first ribs 1013 located on opposite sides of the fixing plate 21. This arrangement can increase the overall mechanical strength of the top plate 101, while limiting and constraining the installation positions of the fixing plate 21 and the heat insulation plate 22, thereby improving assembly efficiency and accuracy.

[0052] Preferably, the fixing plate 21 is provided with a first receiving groove 211 for limiting the assembly of the motor assembly 23, and the heat insulation plate 22 is provided with a second receiving groove 221 at a position corresponding to the first receiving groove 211. This arrangement can serve to position the installation between the fixing plate 21 and the heat insulation plate 22, while reducing the overall height of the hot air structure 2, making the structure of the air fryer microwave oven more compact.

[0053] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
