TECHNICAL FIELD

[0001] The utility model relates to cooking device technical field, especially to the wind shield and steam baking cooking machine. BACKGROUND

[0002] The heat blower baffle is an important barrier between the back heat blower and the customer, which plays an important role in being beautiful and avoiding the customer from directly contacting the sharp heat blower fan blade. In the heat blower scheme, in order to ensure the smooth flow of air, an air inlet hole is arranged on the heat blower baffle corresponding to the fan, which affects the appearance of the cooking machine. In actual use, the fan blade of the heat blower is easy to be stained with oil, and the cooking machine is not designed to allow the customer to touch the fan blade, which causes the psychological burden of the customer who pursues perfection in daily cleaning. In the existing heat blower scheme, the way of increasing the shelter is used to reduce the amount of air entering as much as possible, so that the customer can see the fan blade and other structures inside the cooking machine through the heat blower baffle, which easily causes the loss of air inlet, resulting in the decline of the cooking performance of the cooking machine. SUMMARY

[0003] Based on the problem that the air inlet is reduced when the opening on the heat blower baffle is shielded by increasing the shelter in the existing heat blower scheme, which easily leads to the decline of the cooking performance of the cooking machine, it is necessary to provide the wind shield and the steam baking cooking machine.

[0004] The wind shield is used for covering the heat blower of the cooking device, which comprises:

[0005] a plate body having a shielding area for shielding the heat blower and an air outlet area located at the periphery of the shielding area and provided with an air outlet; and

[0006] a ring body fixed to the air outlet area of the plate body and arranged around the air outlet, the ring body being provided with a plurality of air inlets; wherein the air outlet area of the plate body is provided with a drainage groove extending from the air inlets to the shielding area.

[0007] In this way, the wind shield shields the heat blower, so that the heat blower is not visible, and the drainage groove provided on the wind shield also ensures the smooth air inlet at the air inlet and the smooth circulation of air flow in the inner container. Due to the shielding of the shielding area of the wind shield to the heat blower, the oil stains are prevented from splashing into the fan blade of the heat blower under high temperature conditions, the accumulation of oil stains on the fan blade of the heat blower is reduced in long-term use, and the user can directly clean the wind shield without worrying about the water droplets splashing into the motor of the heat blower during cleaning, which meets the cleaning needs of the user and the visual aesthetic needs when the door is opened.

[0008] In one of the embodiments, the shielding area of the plate body has a containing groove for containing the fan blade of the heat blower, and the containing groove is communicated with the drainage groove.

[0009] In this way, the accommodating groove is used to converge the air flow introduced by the flow guide groove into the covered area, reduces the air flow escaping, and can also reduce the air flow backflow from the air outlet area to the covered area, and increases the certainty of the air flow path.

[0010] In one of the embodiments, the wind shield further comprises a wind spillage prevention plate arranged on the flow guide groove.

[0011] In this way, the air flow is prevented from spilling from the flow guide groove to the air outlet area, and the uniqueness of the air flow path in the cavity where the fan is located is maintained.

[0012] In one of the embodiments, the wind shield further comprises a separation ring extending from the slot of the accommodating groove.

[0013] In this way, the separation ring forms a buffer space with the side wall and the bottom wall of the accommodating groove, so that the air flow entering the accommodating groove from the flow guide groove can be uniformly diffused from the buffer space, and thus the air flow can be uniformly diffused from the accommodating groove to the air outlet area, which is beneficial to ensure that air can be discharged from multiple air outlets.

[0014] In one of the embodiments, the separation ring gradually moves away from the plate body from the outer ring to the inner ring.

[0015] In this way, the volume of the buffer space in the accommodating groove is further expanded, and the separation ring is also used to position the heating pipe and is in heat transfer connection with the heating pipe. The horn-shaped structure has a large heat exchange area with the heating pipe, and the efficiency of heating the air flow is high.

[0016] In one of the embodiments, the accommodating groove is recessed from the covered area to form a boss protruding from the surface of the plate body on the side of the plate body away from the separation ring.

[0017] In this way, the depth of the accommodating groove is expanded, and the air flow entering the accommodating groove from the flow guide groove can be sufficiently buffered, the flow rate is slowed down, the wind vibration is reduced, and the noise is reduced.

[0018] In one of the embodiments, the width of the flow guide groove gradually decreases from the air inlet to the accommodating groove.

[0019] In this way, the air flow has smaller resistance when entering the air inlet, and at the same time, it is more in line with the flow field distribution at the negative pressure port in the natural state, which is beneficial to reduce the vortex in the flow guide groove and reduce the wind noise.

[0020] In one of the embodiments, the ring body further has a plurality of accommodation grooves, and the wind shield further comprises a positioning body arranged in the accommodation grooves and mounted on the ring body, and the positioning body is provided with a bolt hole.

[0021] In this way, the windshield is fixedly connected with the hot air machine or the inner container, and the structural strength of the windshield is increased.

[0022] The application also provides a steam baking cooking machine, which comprises:

[0023] a box assembly;

[0024] an inner container installed in the box assembly;

[0025] a hot air machine installed on the rear wall of the inner container; and

[0026] a windshield as described above, which is arranged in the inner container and covers the hot air machine.

[0027] In this way, the windshield provided by the application can ensure smooth convection of air flow between the fan cavity and the cooking cavity while meeting the requirement of covering the fan blades of the hot air machine.

[0028] In one of the embodiments, the hot air machine comprises a fan body and a heating pipe surrounding the fan body, the heating pipe is in heat transfer connection with the partition ring of the windshield, and the fan body is installed in the accommodating groove of the windshield.

[0029] In this way, the partition ring can not only position the installation of the heating pipe, but also can be in heat transfer connection with the heating pipe to heat the air in the accommodating groove, thereby improving the heating efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0045] The hot air machine baffle is an important barrier between the back hot air machine and the customer, which plays an important role in being beautiful and avoiding the customer directly contacting the sharp hot air machine fan blade. In order to ensure smooth airflow in the hot air machine scheme, an air inlet hole is arranged on the hot air machine baffle corresponding to the fan, which affects the appearance degree of the inside of the cooking machine. In actual use, the fan blade of the hot air machine is also easy to be stained with oil stains, and the cooking machine does not allow the customer to touch the fan blade in design, which causes psychological burden to the customer who pursues perfection in daily cleaning. In the existing hot air machine scheme, other shielding objects are added to reduce the view of the fan blade and other structures inside the cooking machine through the hot air machine baffle as much as possible, but this way is easy to cause loss of air inlet, which leads to decline of the cooking performance of the cooking machine.

[0046] Based on this, it is necessary to provide a wind shield and a steam baking cooking machine which can cancel the front air inlet while still ensuring normal circulation of airflow in the inner container.

[0047] Please refer toFigures 1 to 5 , Figure 1 The structure diagram of the steam baking cooking machine in one embodiment of the utility model, Figure 2 The Figure 1 The sectional view of the steam baking cooking machine shown in the figure A-A, Figure 3 The Figure 2 The local enlarged view of X in the figure, Figure 4 The Figure 2 The front view of the wind shield 10 in the figure, Figure 5 The Figure 4 The side view of the wind shield 10 shown in the figure, Figure 6 The Figure 4 The rear view of the wind shield 10 shown in the figure. The steam baking cooking machine provided in the application comprises a box assembly 40, an inner container 30 installed on the box assembly 40, a hot air machine 20 and a wind shield 10, the hot air machine 20 is installed on the rear wall of the inner container 30, and the wind shield 10 is arranged in the inner container 30 and covers the hot air machine 20. The wind shield 10 comprises a plate body 11 and a ring body 12, the plate body 11 has a covering area 111 and an air outlet area 112, the covering area 111 is used for shielding the hot air machine 20, the air outlet area 112 is located at the periphery of the covering area 111 and is provided with an air outlet 1101, the ring body 12 is fixedly arranged on the air outlet area 112 of the plate body 11 and surrounds the air outlet 1101, and the ring body 12 is provided with a plurality of air inlets 1201. Wherein the air outlet area 112 of the plate body 11 is provided with a flow guide groove 1202 extending from the air inlet 1201 to the covering area 111, so that the wind shield 10 shields the hot air machine 20, so that the hot air machine 20 is not visible, and the flow guide groove 1202 arranged on the wind shield 10 also ensures that the air inlet 1201 is unobstructed and the airflow in the inner container 30 is unobstructed. Due to the shielding of the covering area 111 of the wind shield 10 to the hot air machine 20, the oil stains are prevented from splashing into the fan blade 221 of the hot air machine 20 under high temperature conditions, the accumulation of oil stains on the fan blade 221 of the hot air machine 20 is reduced in long-term use, and the user can directly clean the wind shield 10 without worrying about the water droplets splashing into the motor of the hot air machine 20 during cleaning, which meets the cleaning needs of the user and the visual aesthetic needs when the door is opened.

[0048] Please refer to Figure 2 And Figure 6Specifically, the hot air machine 20 includes a mounting plate 21 fixedly connected to the box body and a fan body 22 mounted on the mounting plate 21, and the mounting plate 21 abuts against the ring body 12 of the wind shield 10 to form the fan cavity 2 together with the wind shield 10. The ring body 12 further has a plurality of accommodation grooves 1203, and the wind shield 10 further includes a positioning body 16 located in the accommodation grooves 1203 and mounted on the ring body 12. The positioning body 16 is provided with bolt holes 1601, and the plate body 11 and the mounting plate 21 are pre-connected into an integrated structure by fastening bolts. It can be understood that the wind shield 10 and the inner container 30 form the cooking cavity 1. When the fan body 22 rotates, the fan blades 221 push the air in the covered area 111 towards the air outlet area 112 located around the covered area 111, and the air in the fan cavity 2 accumulates in the air outlet area 112 and is discharged from the air outlet 1101 into the cooking cavity 1. At the same time, negative pressure is formed in the drainage groove 1202, and the air in the cooking cavity 1 is sucked into the drainage groove 1202, forming air circulation.

[0049] Please refer to Figure 6 and Figure 7 , Figure 7 for Figure 6 the sectional view of the wind shield 10 at B-B. Optionally, in an embodiment provided in the present application, the covered area 111 of the plate body 11 has an accommodation groove 1102 for accommodating the fan blades 221 of the hot air machine 20. The accommodation groove 1102 is communicated with the drainage groove 1202, so that the accommodation groove 1102 is used to converge the air flow introduced by the drainage groove 1202 into the covered area 111, reducing air flow escape. Under the pushing action of the fan blades 221 of the fan body 22, a stable negative pressure area can be formed in the fan cavity 2 at the accommodation groove 1102. The air flow can only enter the covered area 111 from the drainage groove 1202, but cannot flow back to the covered area 111 from the air outlet area 112, increasing the certainty of the air flow path and improving the efficiency of air circulation between the cooking cavity 1 and the fan cavity 2. It can also avoid the noise problem caused by air backflow. Further, in order to prevent air from overflowing from the drainage groove 1202, in an embodiment provided in the present application, the wind shield 10 further includes an anti-overflow plate 13 covering the drainage groove 1202. Specifically, the shape of the anti-overflow plate 13 matches the shape of the drainage groove 1202, and the anti-overflow plate 13 extends from the ring body 12 towards the accommodation groove 1102. In order to further reduce the air backflow from the air outlet area 112 to the accommodation groove 1102, optionally, in an embodiment provided in the present application, the wind shield 10 further includes a partition ring 14 extending from the slot opening of the accommodation groove 1102. The partition ring 14 forms a buffer space 1103 between the side wall and the bottom wall of the accommodation groove 1102. Thus, after the air flow enters the accommodation groove 1102 from the drainage groove 1202, it can be uniformly diffused from the buffer space 1103. Therefore, the air flow can be uniformly diffused from the accommodation groove 1102 to the air outlet area 112, which is conducive to ensuring that multiple air outlets 1101 can all blow air.

[0050] Please refer to Figure 2 and Figure 7 Optionally, in an embodiment provided in the present application, the partition ring 14 gradually moves away from the plate body 11 from the outer ring to the inner ring, so that the slot opening of the accommodating groove 1102 forms a horn-shaped structure, further expanding the volume of the buffer space 1103 in the accommodating groove 1102. The partition ring 14 is also used to position the heating pipe 23 and is in heat transfer connection with the heating pipe 23. Such a horn-shaped structure has a large heat exchange area with the heating pipe 23, and the efficiency of heating the airflow is high. Optionally, in this embodiment provided in the present application, the number of heating pipes 23 is two and is spaced and stacked, one of the heating pipes 23 is sleeved on the partition ring 14, and the other heating pipe 23 is located on the air outlet side of the fan blade 221. Through this double heating mode, the heating efficiency is further improved.

[0051] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 Optionally, in an embodiment provided in the present application, the accommodating groove 1102 is recessed from the covering area 111 to form a boss 15 protruding from the surface of the plate body 11 on the side of the plate body 11 away from the partition ring 14. In this way, the volume of the accommodating groove 1102 is increased, further ensuring the uniformity of airflow diffusion in the accommodating groove 1102. In addition, the depth of the accommodating groove 1102 is further expanded. After the airflow enters the accommodating groove 1102 from the drainage groove 1202, it can be fully buffered, the flow rate is slowed down, the wind vibration is reduced, and the noise is reduced.

[0052] Please refer to Figure 6 Optionally, in an embodiment provided in the present application, the width of the drainage groove 1202 gradually decreases from the air inlet 1201 to the accommodating groove 1102, in other words, the drainage groove 1202 gradually widens outward from the accommodating groove 1102. In this way, the airflow has smaller resistance when entering the air inlet 1201, and at the same time, it is more in line with the flow field distribution at the negative pressure port in the natural state, which is conducive to reducing the vortex in the drainage groove 1202 and reducing the wind noise.

[0053] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0054] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the concept of the utility model, several modifications and improvements can be made, which belong to the protection range of the utility model.
