Description

TECHNICAL FIELD

[0001] The utility model relates to life electric appliance technical field especially, relates to a kind of baking cooking equipment. BACKGROUND

[0002] The position of the air outlet hole for blowing hot air flow in the conventional baking equipment is fixed and unchangeable, and the flow trajectory of the hot air flow in the oven is limited, so the area that can be effectively heated by the hot air flow in the oven is limited, and the food material in the area not passed by the hot air flow is prone to uneven heating, and the user needs to open the oven and perform the tray turning operation during the baking and cooking process, i.e., adjusting the position of the tray with food material in the oven, so that the area with insufficient heating of the food material can be blown by the hot air flow after the tray turning operation. Therefore, the baking equipment has low thermal efficiency, and the taste of the baked food material is not good.

[0003] Currently, there is an improved baking cooking equipment that mainly improves the uneven heating of the food material, and the specific improvement means is to increase the number of air outlet holes and increase the distribution area of the air outlet holes on the hot air fan baffle, i.e., further dispersing the distribution of the air outlet holes on the hot air fan baffle based on the conventional baking equipment to increase the range of the hot air flow in the baking cavity, however, the more dispersed air outlet holes will cause the dispersion of the hot air flow, and each air outlet hole blows a small amount of hot air flow, which seriously reduces the initial kinetic energy of the single hot air flow flowing out of each air outlet hole, and finally causes the speed of the hot air flow blowing over the surface of the food material to decrease significantly, which greatly reduces the efficiency of baking the food material to maturity. SUMMARY

[0004] Therefore, the utility model provides a baking cooking equipment that can improve the uniformity of the heating of the food material and improve the baking efficiency and the taste of the food material.

[0032] The utility model provides a kind of baking cooking equipment, the specific type of baking cooking equipment is not limited, can be traditional oven, can be steaming oven. Figures 1-2 、 Figures 4-5The baking cooking equipment includes an oven assembly 10 and a hot air assembly, the oven assembly 10 has a baking cavity 12, and further includes a fan mounting wall 11 for forming an inner wall of the baking cavity 12, one end of the oven assembly 10 and the fan mounting wall 11 oppositely arranged forms a food material taking and placing opening communicated with the baking cavity 12, the oven door closes the food material taking and placing opening and is oppositely arranged with the fan mounting wall 11 when baking food material, the hot air assembly includes a driving member 51, a fan 41 and a heating member 42, the driving member 51 is installed on one side of the fan mounting wall 11 away from the baking cavity 12, the fan 41 is arranged on the other side of the fan mounting wall 11 towards the baking cavity 12 and is connected with the driving member 51, and the heating member 42 is arranged in the baking cavity 12.

[0033] Further, the baking cooking equipment further includes an air exchange baffle 20 and a linkage mechanism, the air exchange baffle 20 is oppositely arranged with the fan mounting wall 11 and is provided with an air outlet hole 21, the air outlet hole 21 penetrates one side of the air exchange baffle 20 towards the fan mounting wall 11 and the other side of the air exchange baffle 20 away from the fan mounting wall 11, the fan 41 is arranged between the fan mounting wall 11 and the air exchange baffle 20, when the driving member 51 drives the fan 41 to rotate, the airflow formed between the fan mounting wall 11 and the air exchange baffle 20 blows to the other side of the air exchange baffle 20 away from the fan mounting wall 11 through the air outlet hole 21, at least part of the heating member 42 is arranged between the fan mounting wall 11 and the air exchange baffle 20 so as to heat the airflow generated by the fan 41, the linkage mechanism includes a driving member 51 connected with the driving member 51 and a driven member 54 rotatably arranged on the fan mounting wall 11, the driven member 54 has the same rotation center as the fan 41, and the air exchange baffle 20 is fixedly arranged on the driven member 54. The driving member 51 drives the fan 41 to rotate and simultaneously outputs power to the driving member 51, the driven member 54 obtains power and drives the air exchange baffle 20 to rotate around the rotation center of the fan 41.

[0034] In this way, the baking cooking equipment has the following beneficial effects:

[0035] The air exchange baffle 20 replaces the hot air baffle in the prior art, the biggest difference between the air exchange baffle 20 and the hot air baffle lies in that the air exchange baffle 20 can rotate relative to the oven assembly 10, the rotation of the air exchange baffle 20 and the fan 41 in the utility model is driven by the same driving member 51, the number of the driving member 51 is reduced, and the internal structure arrangement and the assembly process of the baking cooking equipment are simplified.

[0036] When the food material in the baking cavity 12 is baked, the air exchange baffle 20 rotates around the rotation center of the fan 41, and the air outlet holes 21 on the air exchange baffle 20 rotate around the rotation center of the fan 41, so that the air outlet holes 21 dynamically change positions in real time, and the position of the hot air flow on the side of the air exchange baffle 20 away from the fan mounting wall 11 dynamically changes in real time, so that the hot air flow is no longer limited to a certain position blowing on the food material, and each part of the food material can obtain heat, improving the uniformity of the food material and the taste, and without dispersing the air outlet holes 21, on the contrary, multiple air outlet holes 21 can be combined, so that the air outlet holes 21 on the air exchange baffle 20 are less and more concentrated, thereby reducing the number of air flow beams and realizing the concentration of the air flow beams, which is beneficial to improve the initial kinetic energy of the hot air flow blowing out of the air outlet holes 21, and the hot air flow with greater kinetic energy can improve the heating efficiency of the food material.

[0037] Further, referring to Figure 1 , Figures 4-5 , the air exchange baffle 20 is also provided with air return holes 22, the air return holes 22 pass through the side of the air exchange baffle 20 facing the fan mounting wall 11 and the other side of the air exchange baffle 20 away from the fan mounting wall 11, the air return holes 22 allow the air flow to flow back from the side of the air exchange baffle 20 away from the fan mounting wall 11 to the side of the air exchange baffle 20 facing the fan mounting wall 11, and after the air flow flows back, it can be disturbed and accelerated by the fan 41 again and heated by the heating element 42 to generate hot air flow again, thereby realizing the circulation of the air flow on both sides of the air exchange baffle 20. The number of air return holes 22 can be multiple, and the multiple air return holes 22 are arranged in a dot matrix form, and the maximum distance from the air return holes 22 to the rotation center of the fan 41 is less than the distance from the air outlet holes 21 to the rotation center of the fan 41, wherein the maximum distance refers to the distance from the farthest air return hole 22 to the rotation center of the fan 41.

[0038] Referring to Figure 1 and Figure 3 , in some embodiments, the linkage mechanism is a planetary gear mechanism, the driving member is a sun gear 52, and the driven member 54 is a rim 541 surrounding the radial outer side of the sun gear 52. The outer periphery of the sun gear 52 and the inner periphery of the rim 541 are respectively provided with gear teeth, and the linkage mechanism further includes a planetary gear 53 arranged between the sun gear 52 and the rim 541. The outer periphery of the planetary gear 53 is provided with gear teeth, and the gear teeth on the outer periphery of the planetary gear 53 are respectively arranged in the sun gear 52 and the rim 541. The rotation center of the driven member 54 is the rotation center of the rim 541, and the air exchange baffle 20 is fixedly connected with the rim 541. The driving member 51 drives the fan 41 to rotate and outputs power to the sun gear 52 at the same time. This part of power is transmitted to the rim 541 through the planetary gear 53, and the rim 541 drives the air exchange baffle 20 to rotate around the rotation center of the fan 41. As Figure 3As shown, the fan 41, the sun gear 52, the wheel rim 541 and the air baffle 20 are coaxially arranged, and their common rotation center is represented by a straight line R. In the present application, the rotation center of the fan 41 is the same element as the axis of the fan 41, and the rotation center of the air baffle 20 is the same element as the axis of the air baffle 20.

[0039] Further, referring to Figure 1 and Figure 3 , the baking cooking device further comprises a planet carrier 60 fixedly connected to the fan mounting wall 11, the planet carrier 60 comprises a gear support 61, the gear support 61 is protrusively arranged relative to the side of the fan mounting wall 11 close to the air baffle 20, the planet wheel 53 is rotationally connected to the gear support 61, and the gear support 61 passes through the planet wheel 53 along the axial direction of the planet wheel 53 from the center of the end of the planet wheel 53, so that the axial position of the planet wheel 53 is defined by the gear support 61, and the axial direction of the planet wheel 53 is fixedly arranged relative to the fan mounting wall 11. In this way, after the power of the sun gear 52 is transmitted to the planet wheel 53, the planet wheel 53 rotates under the constraint of the gear support 61 and cannot roll along the outer circumferential side of the sun gear 52, so that the power is efficiently transmitted to the wheel rim 541 to rotate the air baffle 20.

[0040] Optionally, the planet wheel 53 and the gear support 61 are both configured as a plurality of and are connected one by one in a one-to-one correspondence, the plurality of planet wheels 53 are identical in shape, and the outer diameter of each planet wheel 53 is smaller than the outer diameter of the sun gear 52. In this way, the linkage mechanism not only can obtain a part of the power from the driving member 51 to drive the air baffle 20 to rotate, but also can make the fan 41 and the sun gear 52 rotate at a very high speed under the driving of the driving member 51, while the rotation speed of the wheel rim 541 and the air baffle 20 is significantly reduced, so as to realize the low-speed rotation of the air baffle 20, and the change speed of the position of the air outlet hole 21 is thus significantly reduced, which can prevent the hot air flow wind beam from rapidly changing the position in the baking cavity 12, and can avoid the disorder of the hot air flow in the baking cavity 12 to ensure the baking efficiency by changing the wind beam of the hot air flow in a low-speed gradual manner. It can be understood that when the linkage mechanism is a planetary gear mechanism, the rotation direction of the wheel rim 541 and the rotation direction of the sun gear 52 are opposite, that is, the rotation direction of the fan 41 and the rotation direction of the air baffle 20 are opposite.

[0041] Optionally, referring to Figure 1 and Figure 3 , the driving member 51 comprises a driving motor 511 and a driving shaft 512, the driving motor 511 is fixedly installed on the side of the fan mounting wall 11 opposite to the baking cavity 12, the driving shaft 512 rotationally penetrates the fan mounting wall 11, one end of the driving shaft 512 is connected to the output end of the driving motor 511, and the other end is fixedly connected to the sun gear 52 and the fan 41, and the axis of the driving shaft 512 is the rotation center of the fan 41, the sun gear 52, the wheel rim 541 and the air baffle 20.

[0042] Optionally, referring to Figure 3 , the fan 41 comprises a spoiler 411 for disturbing air to form a hot air flow, the spoiler 411 extends outwardly relative to the rotation center of the fan 41 along the radial direction of the fan 41, and the end of the spoiler 411 away from the rotation center of the fan 41 forms a tail of the fan 41, which is the position where air leaves the fan 41, and the air flow has a certain velocity vector along the radial direction of the fan 41 when it leaves the fan 41. In order to make the hot air flow generated by the fan 41 blow out of the air outlet hole 21 with less kinetic energy loss, the air exchange baffle 20 is configured to cover the fan 41, and the fan 41 can be entirely orthogonally projected on the air exchange baffle 20 along the axial direction, and the minimum distance from the air outlet hole 21 to the rotation center of the fan 41 is greater than the distance from the tail of the fan 41 to the rotation center of the fan 41. When the air exchange baffle 20 is driven by the follower 54 to rotate around the rotation center of the fan 41, the inner diameter of the circular track formed by the rotation of the air outlet hole 21 is greater than the diameter of the circular track formed by the rotation of the tail of the fan 41, so as to adapt the position of the air outlet hole 21 to the inertia of the air flow when it leaves the fan 41.

[0043] In some embodiments, the baking cooking device further comprises a cover 30 fixedly connected with the air exchange baffle 20. Referring to Figures 2-3 、 Figure 6 , the cover 30 comprises a side wall and a back cover 35, the back cover 35 is located on the side of the air exchange baffle 20 facing the fan mounting wall 11, the air exchange baffle 20 and the back cover 35 are arranged in the axial direction of the fan 41 and are spaced apart and face each other, the shapes and sizes of the two are matched, the side wall connects the outer edges of the air exchange baffle 20 and the back cover 35, the side of the air exchange baffle 20 facing the fan mounting wall 11, the back cover 35 and the side wall form a wind cavity, the fan 41 and at least part of the heating element 42 are arranged in the wind cavity, and the air outlet hole 21 and the air return hole 22 communicate with the wind cavity. The wind cavity serves as a place for generating a hot air flow and can collect air flowing back from the side of the air exchange baffle 20 away from the fan mounting wall 11. The wind cavity has a certain degree of sealing, so that the air pressure inside can be increased and maintained when the fan 41 rotates, so that the hot air flow has a larger initial speed after blowing out of the air outlet hole 21 to help the hot air flow flow farther.

[0044] Specifically, referring to Figures 2-3The fan 41 and the inner side of the side wall of the cover 30 are spaced apart, and when the driving member 51 drives the fan 41 to rotate, a speed-up channel 36 is formed between the tail of the fan 41 and the inner side of the side wall. The speed-up channel 36 belongs to the air cavity and surrounds the fan 41 in the circumferential direction of the fan 41. The heating member 42 comprises a heating pipe located in the air cavity. The heating pipe is located radially outside the fan 41 and surrounds the fan 41 in the circumferential direction of the fan 41, that is, the heating pipe is located in the speed-up channel 36. As described above, the driving member 51 drives the fan 41 and the driving member, and finally drives the fan 41 and the air exchange baffle 20 to rotate in different directions, respectively. The cover 30 rotates synchronously with the air exchange baffle 20, so that the relative movement between the tail of the fan 41 and the side wall is generated, and the airflow is accelerated in the speed-up channel 36 while being heated. As the flow rate of the hot air flow in the air cavity increases, the initial speed of the hot air flow when blowing out of the air outlet hole 21 increases.

[0045] Further, as shown in Figures 2-3 The side wall comprises an arc-shaped wall 31 located radially outside the fan 41 and a tangential wall 32. The arc-shaped wall 31 is in the shape of an arc-shaped plate and extends around the center of rotation of the fan 41. The end of the arc-shaped wall 31 is connected tangentially to the end of the tangential wall 32. The tangential wall 32 is in the shape of a flat plate and extends along the tangent direction of the arc-shaped wall 31. The tangent direction of the arc-shaped wall 31 is the tangent direction of the end of the arc-shaped wall 31 connected to the tangential wall 32. The air exchange baffle 20 comprises an arc-shaped section 23, an arm section 24 and a hollow plate connected integrally. The hollow plate is circular and has the air return hole 22. The arc-shaped section 23 and the arm section 24 are connected radially outside the hollow plate. The outer edge of the arc-shaped section 23 away from the center of rotation of the fan 41 is connected to the arc-shaped wall 31. The edge of the arm section 24 away from the center of rotation of the fan 41 is connected tangentially to the edge of the arc-shaped section 23 away from the center of rotation of the fan 41. The outer edge of the arm section 24 away from the center of rotation of the fan 41 is connected to the tangential wall 32. The air outlet hole 21 is formed in the arm section 24. The rear cover 35, the arc-shaped section 23 and the arc-shaped wall 31 form an arc-shaped speed-up channel 36 extending in the circumferential direction of the fan 41. In addition, the air cavity further comprises a tangential air channel 37 connecting the speed-up channel 36 and the air outlet hole 21. The tangential air channel 37 is located on the side of the tangential wall 32 relatively close to the fan 41 and is formed by the rear cover 35, the arm section 24 and the tangential wall 32.

[0046] In this way, the hot air flow in the acceleration channel 36 located radially outside the fan 41 can be concentrated into the tangential air duct 37, which is equivalent to the fan 41 throwing the hot air flow into the tangential air duct 37. Since the tangential wall 32 is tangent to the arc-shaped wall 31 and extends along the tangent direction of the arc-shaped wall 31, the hot air flow entering the tangential air duct 37 from the acceleration channel 36 will not have a drop in flow rate. After entering the tangential air duct 37, the hot air flow flows along the tangent direction of the arc-shaped wall 31 under the guidance of the tangential wall 32 and the arm segment 24 and approaches the air outlet hole 21, and is finally blown out from the air outlet hole 21. This improves the concentration of the hot air flow blowing to the side of the air exchange baffle 20 opposite to the fan mounting wall 11, which helps to improve the initial speed of the hot air flow when it is blown out of the air outlet hole 21, and further improves the speed of the hot air flow blowing on the surface of the food material, so that the food material matures faster.

[0047] Optionally, the tangential walls 32 are arranged in an even number and are symmetric about the rotation center of the fan 41, the tangential air ducts 37 are arranged in an even number and are symmetric about the rotation center of the fan 41, and the air outlet holes 21 are arranged in an even number and are symmetric about the rotation center of the fan 41. As shown in Figures 2-3 The number of the tangential walls 32, the arm segments 24, the tangential air ducts 37 and the air outlet holes 21 is two. The two tangential walls 32 are parallel to each other. The length direction of the two tangential air ducts 37 is perpendicular to the rotation center of the fan 41. One air outlet hole 21 is arranged on each arm segment 24. Each air outlet hole 21 is a single rectangular through hole. Compared with the hot air fan baffle in the prior art, the plurality of dot-matrix distributed air outlet holes 21 are concentrated and integrated in the utility model. The area of the single rectangular air outlet hole 21 is larger, and the number of the air outlet holes 21 is smaller. After the hot air is blown out of each air outlet hole 21, a single wind beam with larger kinetic energy and cross-sectional size is formed, which avoids the mutual interference of multiple wind beams and the insufficient kinetic energy of small wind beams, and affects the roasting effect.

[0048] Figures 2-3 In the embodiment shown, the number of the tangential walls 32, the arm segments 24, the tangential air ducts 37 and the air outlet holes 21 is two. In this way, the air exchange baffle 20 and the cover 30 can have better dynamic balance when rotating, thereby improving the stress on the driving member 51 and prolonging the service life of the driving member 51.

[0049] Further, refer to Figure 2 and Figure 3The side wall of the cover 30 further comprises a bent wall 33 arranged at the radial outer side of the fan 41, the bent wall 33 is bently connected with the arc wall 31, the tangential wall 32 is arranged in parallel with the bent wall 33 and is spaced apart from the bent wall 33, and the tangential air duct 37 is formed between the tangential wall 32 and the bent wall 33. In this way, the hollow shell formed by the cover 30 and the air exchange baffle 20 is similar to the volute of the centrifugal fan as a whole, the bent wall 33 and the arc wall 31 form the volute tongue of the volute, and the air cavity between the cover 30 and the air exchange baffle 20 is similar to the volute air duct in the volute, so that the flow rate of the hot air flow can be further increased, and the initial speed of the hot air flow when blowing out of the air outlet hole 21 is larger.

[0050] For the baking cooking equipment shown in Figure 4 , when the driving member 51 drives the fan 41 to rotate clockwise, the air exchange baffle 20 and the cover 30 rotate counterclockwise, and the position of the hot air flow beam in the baking cavity 12 changes in the counterclockwise direction along the circumference of the fan 41; for the baking cooking equipment shown in Figure 5 , when the driving member 51 drives the fan 41 to rotate counterclockwise, the air exchange baffle 20 and the cover 30 rotate clockwise, and the position of the hot air flow beam in the baking cavity 12 changes in the clockwise direction along the circumference of the fan 41.

[0051] Further, as shown in Figure 6 , in some embodiments, the side wall of the cover 30 is a ring wall 34, the ring wall 34 is arranged at the radial outer side of the fan 41 and extends around the rotation center of the fan 41 to form a closed loop structure, the air exchange baffle 20 and the rear cover 35 are both circular plate structures, and the air cavity comprises a ring-shaped acceleration cavity 36 formed between the tail of the fan 41 and the inner side of the ring wall 34, and the air outlet hole 21 communicates with the acceleration cavity 36.
