Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a cooking device with a stirring and hot air function. Background Technology

[0002] There are many products in the kitchen appliance industry, and the structural design schemes of various kitchen appliances are also diverse. For example, there are many combination products such as microwave steam oven, steam oven, electric oven, gas oven, and gas stove oven, all of which have hot air convection or air fryer functions.

[0003] Some kitchen appliances use rotating hot air stirring blades to heat air via heating wires to heat food. However, because a single stirring blade rotates in one direction, this design can easily lead to uneven hot air mixing inside the oven cavity, resulting in uneven heating of the food. Installing two hot air stirring blades, with both blades rotating in opposite directions simultaneously, can solve the problem of evenly mixing the hot air to some extent. However, the airflow from two adjacent blades rotating in opposite directions can easily cause mutual turbulence, affecting the uniformity of temperature distribution inside the oven cavity. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a cooking device with a stirring hot air function, which can improve the heat uniformity inside the oven cavity.

[0005] To achieve the above objectives, this utility model provides a cooking device with a stirring hot air function. The cooking device includes a furnace body, a baffle plate, a stirring fan blade, a drive assembly, and a first heating element. The furnace body has a furnace cavity with a first wall surface. The baffle plate is disposed within the furnace cavity, opposite to the first wall surface and spaced apart from the inner wall of the furnace cavity. The stirring fan blade is located between the baffle plate and the first wall surface, spaced apart from both. The stirring fan blade includes a rotating base and a blade assembly. The blade assembly is disposed on the rotating base. Multiple blade assemblies are arranged sequentially and spaced apart around a rotation axis. Each blade assembly includes two blades, which are symmetrically arranged and spaced apart relative to a direction perpendicular to the rotation axis. The drive assembly is connected to the rotating base and can drive the rotating base to rotate alternately clockwise and counterclockwise around the rotation axis. The first heating element is arranged around the periphery of the rotating base.

[0006] Furthermore, the rotating seat is provided with a first port, and multiple first ports are provided and spaced apart around the rotation axis; one end of two blades in the same blade group is respectively connected to the sidewalls of two adjacent first ports that are far apart from each other.

[0007] Furthermore, the width direction of the blade is parallel to the axial direction of the rotation axis.

[0008] Furthermore, an insert block is provided on the first wall surface, and the insert block has a circular cross-section; a slot is provided on the end face of the wind deflector opposite to the first wall surface, the insert block passes through the slot, and the wind deflector is spaced apart from the first wall surface.

[0009] Furthermore, it also includes a hot air mesh cover, and a second opening is provided on the wind deflector plate, which is disposed opposite to the middle of the rotating seat; the hot air mesh cover is disposed at the second opening.

[0010] Furthermore, the furnace body includes a bottom plate and side plates, and multiple side plates are provided and connected end to end in sequence. The bottom plate is connected to one end of the multiple side plates. The furnace cavity is defined between the bottom plate and the multiple side plates. The end face of the bottom plate facing the furnace cavity is the first wall surface. The wind baffle is provided at intervals with the multiple side plates.

[0011] Furthermore, it also includes a second heating element, which is disposed on the base plate or the side plate.

[0012] Furthermore, multiple second heating elements are provided, and the multiple second heating elements are respectively disposed on the base plate and / or the side plate.

[0013] Furthermore, the drive assembly includes a drive component, a rotating shaft, and a fixed bracket; the fixed bracket is connected to the outer side of the furnace body away from the furnace cavity, the drive component is connected to the fixed bracket and to the rotating shaft, and the drive component can drive the rotating shaft to rotate clockwise and counterclockwise alternately around the rotation axis; one end of the rotating shaft passes through the furnace body and is connected to the rotating seat.

[0014] Furthermore, the drive assembly also includes a balancing pad; the blade assembly is disposed on the side of the rotating seat near the wind deflector, and the balancing pad is sleeved on the rotating shaft and abuts against the side end of the rotating seat away from the wind deflector.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] In this embodiment of the invention, food can be placed inside the oven cavity, specifically on the part of the baffle plate away from the stirring blades. The drive assembly drives the rotating seat to rotate, thereby causing the blade assembly on the rotating seat to rotate around the rotation axis. Since the stirring blades are located between the baffle plate and the first wall surface, the air generated when the blade assembly rotates can flow outward from between the baffle plate and the first and inner walls of the oven cavity. The first heating element is arranged around the periphery of the rotating seat, allowing it to heat the air flowing into the oven cavity, thus heating the food inside the oven cavity. Because the blade assembly consists of two blades, and the two blades are symmetrically positioned perpendicular to the rotation axis, the drive assembly can drive the rotating seat to rotate. The rotating seat rotates clockwise around the rotation axis, generating a clockwise whirlwind through one of the blades in the blade assembly. The drive assembly can also drive the rotating seat to rotate counter-clockwise around the rotation axis, generating a counter-clockwise whirlwind through the other blade in the blade assembly. In this embodiment, the cooking device with a stirring hot air function can be driven by the drive assembly to rotate the rotating seat back and forth clockwise and counter-clockwise sequentially, thereby generating clockwise and counter-clockwise whirlwinds through the blade assembly. This achieves uniform heat mixing within the oven cavity, improves the overall temperature uniformity within the oven cavity, and allows for more even heating of the food within the oven cavity, resulting in better cooking performance.

[0027] Please see Figures 1 to 4This utility model provides a cooking device with a stirring and hot air function. The cooking device includes a furnace body 100, a baffle plate 200, a stirring fan blade 300, a drive assembly 400, and a first heating element 500. The furnace body 100 has a furnace cavity 110 with a first wall surface 111. The baffle plate 200 is disposed within the furnace cavity 110, opposite to the first wall surface 111 and spaced apart from the inner wall of the furnace cavity 110. The stirring fan blade 300 is located between the baffle plate 200 and the first wall surface 111, and is positioned between the baffle plate 200 and the first wall surface 111. 111 Interval arrangement; the stirring fan 300 includes a rotating base 310 and a blade assembly 320; the blade assembly 320 is disposed on the rotating base 310; multiple blade assemblies 320 are provided and are arranged alternately around the rotation axis; the blade assembly 320 includes two blades 321, which are symmetrically arranged with respect to the direction perpendicular to the rotation axis and are arranged alternately; the drive assembly 400 is connected to the rotating base 310; the drive assembly 400 can drive the rotating base 310 to rotate clockwise and counterclockwise alternately around the rotation axis; the first heating element 500 is arranged around the periphery of the rotating base 310.

[0028] In this embodiment of the invention, food can be placed inside the oven cavity 110, specifically on the part of the baffle plate 200 away from the stirring fan blade 300. The drive assembly 400 drives the rotating seat 310 to rotate, thereby causing the blade assembly 320 on the rotating seat 310 to rotate around the rotation axis. Since the stirring fan blade 300 is located between the baffle plate 200 and the first wall surface 111, the air generated when the blade assembly 320 rotates can flow outward from between the baffle plate 200 and the first wall surface 111 and the inner wall of the oven cavity 110. The first heating element 500 is arranged around the periphery of the rotating seat 310, allowing it to heat the air flowing into the oven cavity 110, thus heating the food inside the oven cavity 110. The blade assembly 320 consists of two blade assemblies 321, and the two blades 321 are symmetrically oriented perpendicular to the rotation axis. The direction allows the drive assembly 400 to drive the rotating seat 310 to rotate clockwise around the rotation axis, so that one of the blades 321 of the blade assembly 320 can generate a clockwise whirlwind. The drive assembly 400 can also drive the rotating seat 310 to rotate counterclockwise around the rotation axis, so that the other blade 321 of the blade assembly 320 can generate a counterclockwise whirlwind. In this embodiment, the cooking device with a stirring hot air function can drive the rotating seat 310 to rotate clockwise and counterclockwise sequentially via the drive assembly 400, thereby generating clockwise and counterclockwise whirlwinds sequentially via the blade assembly 320. This achieves uniform heat mixing inside the oven cavity 110, improves the overall temperature uniformity inside the oven cavity 110, and allows the food inside the oven cavity 110 to be heated more evenly, resulting in better cooking effects.

[0029] Reference Figure 2 and Figure 3 In some embodiments of this utility model, the rotating seat 310 is provided with a first port 311, and multiple first ports 311 are provided and spaced apart around the rotation axis; one end of two blades 321 of the same blade group 320 is respectively connected to the sidewalls of two adjacent first ports 311 that are far apart from each other.

[0030] Each of the first openings 311 has a blade 321 installed on its inner wall.

[0031] The first opening 311 can increase the air intake, so that the blades 321, driven by the rotating seat 310, can push more airflow, thereby increasing the airflow blown into the furnace cavity 110. Specifically, the first opening 311 is provided through the opposite side of the rotating seat 310, and the first opening 311 is opposite to the first wall surface 111 and the baffle plate 200.

[0032] Among them, two adjacent first openings 311 are located between two blades 321 of the same blade group 320 to ensure the stability of the first air outlet, and can be matched with two blades 321 respectively.

[0033] Specifically, the number of blades 321 is equal to the number of first openings 311; the blades 321 and the rotating seat 310 are integrally formed, and the blades 321 and the first openings 311 can be formed simultaneously by cutting and bending.

[0034] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the width direction of the blade 321 is arranged parallel to the axial direction of the rotation axis, so as to maximize the contact area between the blade 321 and the air during the rotation of the stirring fan 300, thereby improving the effect of blowing air.

[0035] Specifically, the length direction of the blade 321 is perpendicular to the axial direction of the rotation axis.

[0036] Reference Figure 1 and Figure 2 In some embodiments of this utility model, a plug is provided on the first wall surface 111, and the cross-section of the plug is circular; a slot 210 is provided on the end face of the wind baffle 200 opposite to the first wall surface 111, and the plug is disposed in the slot 210.

[0037] After the baffle plate 200 is placed inside the furnace cavity 110, the baffle plate 200 is positioned opposite to the first wall surface 111. An insert is provided on the end face of the first wall surface 111 facing the furnace cavity 110, and a slot 210 is provided on the end face of the baffle plate 200 opposite to the first wall surface 111. The insert is inserted into the slot 210 to fix the position of the baffle plate 200 and to make the distance between the baffle plate 200 and the first wall surface 111 equal.

[0038] Specifically, the cross-section of the insert increases continuously along the direction close to the first wall surface 111 to prevent the insert from being over-inserted into the slot 210, thereby limiting the distance between the baffle plate 200 and the first wall surface 111. The airflow generated by the stirring blade 321 rotating between the baffle plate 200 and the first wall surface 111 will pass through the insert. The insert has a cylindrical structure, making its cross-section circular, so as to reduce the loss of airflow when it passes through and ensure the amount of airflow blown into the furnace cavity 110.

[0039] Specifically, slots 210 are located at the edge of the baffle plate 200 to further reduce the loss of airflow by the inserts; multiple slots 210 are provided and are respectively located at the four corners of the baffle plate 200, and multiple inserts are also provided, with multiple inserts inserted into multiple slots 210 respectively.

[0040] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments of this utility model, a hot air mesh cover 600 is also included. A second opening 220 is provided on the baffle plate 200, and the second opening 220 is disposed opposite to the rotating seat 310. The hot air mesh cover 600 is disposed at the second opening 220.

[0041] The hot air mesh cover 600 has many openings arranged on it. The air blown out by the stirring fan 300 during rotation can be sent into the furnace cavity 110 through the hot air mesh cover 600, so that the air can be blown towards the center of the furnace cavity 110, thereby improving the uniformity of heating of the food in the furnace cavity 110 and the uniformity of heat.

[0042] Specifically, in some other embodiments of this utility model, during the rotation of the stirring fan blade 300, air can return from the second port 220, and by setting the hot air mesh cover 600, food residue can be blocked from being blown toward the stirring fan blade 300.

[0043] Reference Figure 1 and Figure 2In some embodiments of this utility model, the furnace body 100 includes a bottom plate 101 and side plates 102. Multiple side plates 102 are provided and connected end to end in sequence. The bottom plate 101 is connected to one end of the multiple side plates 102. A furnace cavity 110 is formed between the bottom plate 101 and the multiple side plates 102. The end face of the bottom plate 101 facing the furnace cavity 110 is the first wall surface 111. The multiple side plates 102 and the baffle plate 200 are all spaced apart.

[0044] The baffle plate 200 and the stirring fan 300 are located between multiple side plates 102, and the stirring fan 300 is positioned opposite to the first wall surface 111 on the bottom plate 101. The edge of the baffle plate 200 is spaced apart from the multiple side plates 102, forming a first space between the baffle plate 200 and the first wall surface 111. A second space is formed around the periphery of the first space on the bottom plate 101. When the stirring fan 300 rotates clockwise within the furnace cavity 110, it can form a first set of cyclones in the first space and a second set of cyclones in the second space. It can achieve the formation of two clockwise cyclones on the bottom plate 101; while when the stirring fan 300 rotates counterclockwise in the furnace cavity 110, it can form a third set of cyclones in the first space and a fourth cyclone in the second space, so as to achieve the formation of two counterclockwise cyclones on the bottom plate 101. Specifically, four side plates 102 are provided, and the four sides of the baffle plate 200 are spaced apart from the four side plates 102, so that the airflow stirred by the stirring fan 300 can be blown into the furnace cavity 110 from between the baffle plate 200 and the side plates 102.

[0045] In some embodiments of this utility model, a second heating element is also included. The second heating element is disposed on the bottom plate 101 or the side plate 102 so that the bottom plate 101 or the side plate 102 can be heated by the second heating element, thereby heating the food and air in the furnace cavity 110 and improving the heating effect.

[0046] In some embodiments of this utility model, multiple second heating elements are provided.

[0047] By setting up multiple secondary heating elements, the heating effect can be further improved.

[0048] Specifically, multiple second heating elements are respectively arranged at the four side plates 102 to improve the uniform heating effect.

[0050] The fixed bracket 430 fixes the position of the drive component 410 relative to the furnace body 100. The drive component 410 drives the rotating shaft 420 to rotate, thereby enabling the blade assembly 320 to rotate.

[0051] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the drive assembly 400 further includes a balance pad 440; the blade assembly 320 is disposed on the side of the rotating seat 310 near the baffle plate 200, so that the cyclone formed by the stirring fan blade 300 during rotation will be between the rotating seat 310 and the baffle plate 200, so as to limit the cyclone from flowing outward between the rotating seat 310 and the baffle plate 200; the balance pad 440 is sleeved on the rotating shaft 420 and abuts against the side of the rotating seat 310 away from the baffle plate 200.
