Description
Technical Field
[0001] The utility model relates to the technical field of kitchen appliances, in particular to a machine head and an integrated stove. Background Art
[0002] An integrated stove is a kitchen appliance that integrates multiple functions such as a range hood, a gas stove, a disinfection cabinet, and a storage cabinet, and has the advantages of saving space, good oil fume extraction effect, energy saving, low consumption, and environmental protection.
[0003] As Figure 1 shown, the machine head of the existing integrated stove includes a machine head housing 10 and a blower 40. The machine head housing 10 includes a smoke guide plate 101 and a back plate 102 arranged in sequence along the front-rear direction. The smoke guide plate 101 and the back plate 102 enclose a smoke guide channel 20. The top end of the smoke guide channel 20 communicates with the outside through a smoke inlet 30. The smoke inlet 30 is opened upward. The blower 40 is arranged below the machine head housing 10 and communicates with the smoke guide channel 20. The upper end of the smoke guide plate 101 adopts a straight structure. Under the negative pressure provided by the blower 40, the oil fume generated in the cooking pot needs to first climb vertically upward along the smoke guide plate 101, then turn 90° and flow horizontally, and then turn 90° again and enter the smoke guide channel 20. During this process, the oil fume is not effectively guided when passing over the smoke guide plate 101, and eddy currents are likely to be generated at the turning point, which is likely to cause oil fume escape and waste the power provided by the blower 40, affecting the oil fume extraction effect. Summary of the Utility Model

The first smoke guide surface and the second smoke guide surface are arranged at intervals in the front-rear direction. The two connecting surfaces are symmetrically arranged on the left and right sides of the second smoke guide surface, and both of the two connecting surfaces are connected between the first smoke guide surface and the second smoke guide surface. The first smoke guide surface, the second smoke guide surface and the two connecting surfaces enclose the smoke guide channel.
[0011] As a preferred technical solution of the machine head, the front end of the connecting surface is connected to the first smoke guide surface, and the rear end of the connecting surface is connected to the second smoke guide surface;

[0018] The smoke guide plate of the machine head includes a front end face, a first smoke guide face, and a guiding face.

In the vertical direction, the rear end of the guiding face is higher than the front end of the guiding face. Under the negative pressure provided by the fan, the cooking fume climbs to the top end of the front end face and is then guided to the upper part of the smoke guide channel through the guiding face.

[0036] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0037] Please refer to Figures 2 to 5 , this embodiment provides an integrated stove, which includes a machine head 100, a gas stove 300, and a frame 200. The machine head 100 and the gas stove 300 are both arranged on the frame 200. The gas stove 300 is used for cooking, and the machine head 100 is used for collecting and discharging the oil fume generated during the cooking process. Among them, the integrated stove further includes a fan 500, and the fan 500 is arranged inside the frame 200 and below the machine head 100. The machine head 100 collects the oil fume under the power provided by the fan 500.
[0038] Specifically, the machine head 100 includes a machine head housing. The machine head housing 1 includes a smoke guide plate 11 and a back plate 12 connected to the smoke guide plate 11. The smoke guide plate 11 is located in front of the back plate 12 and close to the gas stove 300. The smoke guide plate 11 and the back plate 12 enclose a smoke guide channel 31. The top end of the smoke guide channel 31 communicates with the outside through a smoke inlet 32, and the smoke inlet 32 is opened upward. The input end of the fan 500 is communicated with the smoke guide channel 31, and the output end of the fan 500 is used to connect to a smoke exhaust pipe. Under the action of the negative pressure provided by the fan 500, the oil fume generated during the cooking process can enter the smoke guide channel 31 through the smoke inlet 32 and then be discharged into the smoke exhaust pipe. Among them, in this embodiment, the front-back direction is as Figure 2 shown by the ab arrow in Figure 2 , the vertical direction is as Figure 2 shown by the cd arrow in
[0039] Optionally, the integrated stove further includes a function module 400 installed on the frame 200. The function module 400 can be a disinfection cabinet, a steaming box, an oven and other functional devices. By integrating different function modules 400 in the integrated stove, the integrated stove can integrate different functions to meet the different needs of users.
[0040] In the existing integrated stove, the upper end of the smoke guide plate adopts a straight structure. Under the action of the negative pressure provided by the fan, the oil fume generated in the cooking pot needs to first climb vertically upward along the smoke guide plate, then turn 90° and flow horizontally, and then turn 90° again and enter the smoke guide channel. During this process, the oil fume is not effectively guided when crossing the smoke guide plate, and eddy currents are likely to be generated at the turning points, which is likely to cause the oil fume to escape and will also waste the power provided by the fan, affecting the oil fume extraction effect.
[0041] In this embodiment, the smoke guide plate 11 includes a front end face 111, a first smoke guide face 112, and a guiding face 113. The front end face 111 and the first smoke guide face 112 are spaced apart in the front-rear direction. The first smoke guide face 112 is used to enclose a part of the smoke guide channel 31. The front end of the guiding face 113 is connected to the top end of the front end face 111, and the rear end of the guiding face 113 is connected to the top end of the first smoke guide face 112. In the vertical direction, the rear end of the guiding face 113 is higher than the front end of the guiding face 113. With such a setting, under the action of the negative pressure provided by the fan 500, the oil fume climbs to the top end of the front end face 111 and is then guided to the upper part of the smoke guide channel 31 through the guiding face 113. Since the rear end of the guiding face 113 is relatively higher than the front end of the guiding face 113, the path between the front end face 111 - the guiding face 113 - the smoke inlet 32 can be made relatively smooth. Compared with the flat structure at the upper end of the existing smoke guide plate 11, the generation of eddy currents can be avoided, and the escape of oil fume can be avoided, thereby saving the power of the fan 500 and ensuring the oil fume suction effect of the integrated stove.
[0042] It should be noted that the top end of the first smoke guide face 112 is used to enclose a part of the smoke inlet 32. Therefore, the guiding face 113 can directly guide the oil fume from the front end face 111 to the upper part of the smoke inlet 32.
[0043] Among them, please refer to Figure 2 and Figure 3 , the guiding face 113 can be set as an arc surface. The arc surface is smoothly transitioned with the top end of the front end face 111. Thus, when the oil fume climbs to the top end of the front end face 111, it can enter the arc surface without obstruction, which can significantly improve the passing efficiency of the oil fume, avoid the generation of eddy currents and the escape of oil fume. In addition, the arc surface also has a relatively large pressure-bearing area, which can reduce the pressure of the oil fume airflow here, and further reduce the power loss of the oil fume airflow, and can further improve the oil fume suction effect of the integrated stove.
[0044] Please refer to Figure 4 , the guiding face 113 can also be set as a plane. At this time, an obtuse angle is formed between the guiding face 113 and the front end face 111. Compared with the 90° turning angle at the upper end of the existing smoke guide plate 11, after the oil fume climbs to the top end of the front end face 111, it can relatively easily cross the turning angle in the form of an obtuse angle and enter the guiding face 113. Similarly, the passing efficiency of the oil fume can be improved, the generation of eddy currents and the escape of oil fume can be reduced, and the oil fume suction effect of the integrated stove can also be improved.
[0045] Optionally, please refer to Figure 3, in this embodiment, the front end face 111 is inclined, and at this time, the front end face 111 forms an angle with the horizontal plane. Specifically, along the front-back direction, the top end of the front end face 111 is located behind the bottom end of the front end face 111. When the cooking fume climbs along the front end face 111, the climbing angle is less than 90°, which is relatively easier and can further improve the fume extraction effect of the integrated stove.
[0046] As an alternative solution, please refer to Figure 4 , the front end face 111 can also be set perpendicular to the horizontal plane. When the cooking fume climbs along the front end face 111, it needs to be in the vertical direction at this time.
[0047] Optionally, please refer to Figure 3 , the input end of the fan 500 is communicated with the bottom end of the smoke guide channel 31; along the vertical direction, the cross-sectional area of the smoke guide channel 31 gradually increases from top to bottom. With such a setting, according to Bernoulli's principle, in the entire smoke guide channel 31, the overall flow velocity of the gas at the smoke inlet 32 is the largest, which can further improve the fume extraction effect of the integrated stove.
[0048] Specifically, please refer to Figure 2 and Figure 5 , in this embodiment, the back plate 12 includes a second smoke guide surface 121 and two connecting surfaces 122: the first smoke guide surface 112 and the second smoke guide surface 121 are arranged at intervals along the front-back direction, and the two connecting surfaces 122 are symmetrically arranged on the left and right sides of the second smoke guide surface 121, and both of the two connecting surfaces 122 are connected between the first smoke guide surface 112 and the second smoke guide surface 121. The first smoke guide surface 112, the second smoke guide surface 121 and the two connecting surfaces 122 enclose the smoke guide channel 31.
[0049] Among them, please continue to refer to Figure 2 and Figure 5 , along the vertical direction, the distance between the first smoke guide surface 112 and the second smoke guide surface 121 gradually increases from top to bottom, and the distance between the two connecting surfaces 122 remains unchanged or gradually increases from top to bottom, so as to realize that the cross-sectional area of the smoke guide channel 31 gradually increases from top to bottom.
[0050] Furthermore, please refer to 3. In this embodiment, the first smoke guide surface 112 is inclined relative to the horizontal plane, and the second smoke guide surface 121 is also inclined relative to the horizontal plane. Specifically, from bottom to top, both the first smoke guide surface 112 and the second smoke guide surface 121 incline towards the middle of the two, so as to realize that the distance between the first smoke guide surface 112 and the second smoke guide surface 121 gradually increases from top to bottom.
[0051] As an alternative solution, the first smoke guide surface 112 can also be inclined relative to the horizontal plane, and the second smoke guide surface 121 can be perpendicular to the horizontal plane. Specifically, the top end of the first smoke guide surface 112 is closer to the second smoke guide surface 121 than the bottom end of the first smoke guide surface 112, which can also make the distance between the first smoke guide surface 112 and the second smoke guide surface 121 gradually increase from top to bottom.
[0052] As an alternative solution, please refer to Figure 4 , it is also possible to make the first smoke guide surface 112 perpendicular to the horizontal plane and the second smoke guide surface 121 inclined relative to the horizontal plane. Specifically, the top end of the second smoke guide surface 121 is closer to the first smoke guide surface 112 than the bottom end of the second smoke guide surface 121, which can also make the distance between the first smoke guide surface 112 and the second smoke guide surface 121 gradually increase from top to bottom.
[0053] Optionally, please refer to Figures 2 to 4 , in this embodiment, the top end of the back plate 12 is higher than the top end of the smoke guide plate 11, and the second smoke guide surface 121 and the two connecting surfaces 122 both partially extend above the air inlet 32. With such a setting, the parts of the second smoke guide surface 121 and the two connecting surfaces 122 extending above the air inlet 32 can guide the oil fume at a high position downward to the air inlet 32 below, so as to further enhance the oil fume extraction effect of the integrated range hood. Of course, in other embodiments, the height of the top end of the back plate 12 can also be set to be the same as the height of the top end of the smoke guide plate 11, and the heights of the top ends of the first smoke guide surface 112, the two connecting surfaces 122, and the second smoke guide surface 121 are all the same.
[0054] Optionally, please refer to Figures 2 to 4 , the machine head 100 further includes a storage plate 2, and the storage plate 2 is arranged at the top end of the back plate 12. With such a setting, items such as tableware and seasonings can be placed on the storage plate 2. Preferably, the rear end of the storage plate 2 is connected to the top end of the back plate 12, and the front end of the storage plate 2 is suspended and located above the gas stove 300. In this way, the upward diffusing oil fume can also be collected by the storage plate 2, so as to further improve the oil fume extraction effect of the integrated range hood.
[0055] In other embodiments, the storage plate 2 can also be replaced with a fume collecting plate. Although the fume collecting plate does not have the function of placing items, it has the function of collecting the upward diffusing oil fume.
[0056] Optionally, please refer to Figure 2 and Figure 5, the front end of the connecting surface 122 is connected to the first smoke guiding surface 112, and the rear end of the connecting surface 122 is connected to the second smoke guiding surface 121. The distance between the rear ends of the two connecting surfaces 122 is less than the distance between the front ends of the two connecting surfaces 122. Along the left-right direction, the air flow dynamic center line of the fan 500 is located between the two connecting surfaces 122. Among them, the air flow dynamic center line of the fan 500 is the line formed after the air flow dynamic center of the fan 500 extends to the smoke guiding channel 31, and the suction at the air flow dynamic center of the fan 500 is greater than the suction at the outer periphery of the air flow of the fan 500; therefore, the suction at the air flow dynamic center line of the fan 500 is relatively strong. Since the distance between the rear ends of the two connecting surfaces 122 is less than the distance between the front ends of the two connecting surfaces 122, the two connecting surfaces 122 are inclined relative to the second smoke guiding surface 121 and are inclined from both the left and right sides towards the middle. Furthermore, both of the two connecting surfaces 122 can guide the oil fume air flow flowing towards them towards the middle, so that the oil fume air flow can approach the air flow dynamic center line of the fan 500 with a shorter flow path, which is convenient for reducing the loss of the oil fume air flow during this process and further improving the oil fume suction effect of the integrated range hood.
[0057] In other embodiments, the two connecting surfaces 122 may also be arranged parallel and spaced apart in the left-right direction, and the two connecting surfaces 122 are respectively perpendicular to the first smoke guiding surface 112 and the second smoke guiding surface 121.
[0058] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here.
