Description

Technical Field

[0001] This invention relates to the field of cooktop technology, and more particularly to a range hood head and an integrated cooktop. Background Technology

[0002] An integrated cooktop is a device that combines cooking and fume extraction functions. The fume extraction function is represented by the range hood head. The range hood head typically has a connected motor and a flap. When fume extraction is needed, the motor pushes the flap open, allowing fumes to enter the air intake channel inside the range hood head through the air inlet until they are completely exhausted or purified. After fume extraction is complete, the motor pulls the flap back to its original position, blocking the air inlet for a more aesthetically pleasing appearance.

[0003] Currently, one or more linkage structures are usually required between the motor and the flap. The force of the motor push rod needs to be transmitted through the linkage structure before it can be applied to the flap, which leads to unstable flap movement and may even cause the flap to jam. It also has poor durability. The connection relationship of the linkage structure is complicated, the disassembly and assembly efficiency is low, and it is prone to loosening and other failures.

[0004] In existing range hoods, the motor is usually installed on the side, and the flap is subjected to force on one side when it opens and closes, making the flap prone to tilting and deformation; the space around the motor is narrow, making maintenance inconvenient. Summary of the Invention

[0005] The purpose of this invention is to provide a range hood head and integrated stove that improves the stability and durability of the smoke baffle.

[0006] To achieve this objective, the present invention employs the following technical solution:

The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are for illustrative purposes only and are not the only embodiment.

[0034] The present embodiment provides a smoke machine head and an integrated stove including the smoke machine head. Specifically, the integrated stove further includes a stove main machine, and the smoke machine head is fixedly connected to the stove main machine. As shown in Figures 1 to 4As shown, the smoke hood head includes a head body 1, a smoke guide plate 2, a smoke baffle 3, and a push rod motor 5. The smoke guide plate 2 and the head body 1 form an air inlet channel 4 for the smoke to pass through. The smoke guide plate 2 has an air inlet 21. The smoke baffle 3, movably connected to the head body 1, can block or open the air inlet 21. The output shaft 51 of the push rod motor 5 is hinged to the inner side of the smoke baffle 3, used to drive the smoke baffle 3 to open or close. The smoke baffle 3 includes a main plate surface 31 and an inclined plate surface 32 extending upwards along the top edge of the main plate surface 31. The horizontal distance between the inclined plate surface 32 and the head body 1 gradually decreases from bottom to top. Correspondingly, the position on the head body 1 that contacts the inclined plate surface 32 is also oblique, designed not to obstruct the opening and closing of the inclined plate surface 32.

[0035] The bottom of the push rod motor 5 is connected to the inner side of the head body 1 at connection point a. The connection point between the output shaft 51 and the smoke baffle 3 is b, and the connection point between the smoke baffle 3 and the head body 1 is c. Throughout the entire movement of the smoke baffle 3, from closing to opening, connection point b is always located in front of the line connecting connection points a and c. It should be noted that "front" refers to the side closer to the smoke guide plate 2, that is, the side facing the user.

[0036] The top of the smoke baffle 3 has reduced the triangular-shaped area ( Figure 3 (The area shown by the dashed line) and the connection point c between the smoke baffle 3 and the main body 1 of the machine head is moved backward, so that the output shaft 51 of the push rod motor 5 can be directly hinged to the inner side of the smoke baffle 3 without the need for a complex connecting transmission mechanism (such as a connecting rod or a slide) for transition connection. The thrust and pull on the output shaft 51 can act directly on the smoke baffle 3, avoiding the failure of the smoke baffle 3 due to the loosening of the connecting rod and other structures, and improving the stability and durability of the smoke baffle 3.

[0037] Based on the above structure, a push rod support seat 33 is provided on the inner side of the end where the inclined plate surface 32 connects to the main plate surface 31, and the output shaft 51 is hinged to the push rod support seat 33. The output shaft 51 pushes and pulls more smoothly, the movement state of the smoke baffle 3 is more stable, and the reaction force from the smoke baffle 3 on the push rod motor 5 is more balanced.

[0038] The smoke baffle 3 is preferably connected to the machine head body 1 via rocker arms 34. In order to improve the stability of the smoke baffle 3, rocker arms 34 are respectively provided at the left and right ends of the inclined plate surface 32. The push rod motor 5 is located in the middle of the machine head body 1, and the two rocker arms 34 are symmetrically arranged about the push rod motor 5.

[0039] That is, the push rod motor 5 is installed in the middle vertical area of ​​the machine head body 1. The central placement of the push rod motor 5 solves the problem of uneven force on the flip plate caused by the single-sided installation of the drive device in the prior art. The push rod motor 5 is easy to install and remove and has a large operating space, which improves the convenience of maintenance.

[0040] On the basis of the above structure, the top of the machine head body 1 is provided with a rocker arm fixing seat 6, as shown in Figure 5 and Figure 6 The rocker arm 34 is hinged on the rocker arm fixing seat 6 through a hinge shaft 61. The mounting structure of the rocker arm 34 is more stable, and it is convenient to disassemble and assemble. When the push rod motor 5 drives the smoke baffle 3 to open and close, the rocker arm 34 swings around the hinge shaft 61, avoiding the movement of the smoke baffle 3 from being stuck.

[0041] As shown in Figure 5 and Figure 6 A groove 62 is formed on the rocker arm fixing seat 6, and one side end of the rocker arm 34 is arranged in the groove 62. The hinge shaft 61 passes through the side wall of the groove 62, the rocker arm 34 and the other side wall of the groove 62 in sequence. The two side walls can fix the rocker arm 34, avoiding the lateral shaking of the rocker arm 34 during swinging, and ensuring the stability and durability of the smoke baffle 3.

[0042] On the basis of the above structure, a limiting portion 63 is arranged on the rocker arm fixing seat 6. When the smoke baffle 3 is opened to a certain angle, the rocker arm 34 abuts against the limiting portion 63, which can effectively prevent the output shaft 51 from overtraveling to cause the smoke baffle 3 to open too large, and ensure the movement of the smoke baffle 3 to be more stable and controllable.

[0043] The specific shape of the inclined plate surface 32 is not limited, and the width of the smoke baffle 3 gradually decreases in the direction from bottom to top. Preferably, as shown in Figure 3 The inclined plate surface 32 is a plane structure, which is convenient to process and has a more beautiful appearance. The included angle α between the inclined plate surface 32 and the vertical surface is ∈ [30°, 40°], and is preferably 35°, which is more convenient to connect the push rod motor 5, the extension of the output shaft 51 is more smooth, and the movement track of the smoke baffle 3 is more reasonable.

[0044] Of course, the arc surface structure is convex outward, and its function and effect are basically the same as those of the plane structure. It is convenient for the user to select the device with the corresponding shape according to the preference, and the application range is wide.

[0045] On the basis of the above structure, a motor fixing seat 7 is arranged on the inner side surface of the machine head body 1, and the bottom of the push rod motor 5 is hinged on the motor fixing seat 7. When the smoke baffle 3 is pushed and pulled, the horizontal position and the vertical position of the connection point b will change to a certain extent. In order to avoid the movement from being stuck, the push rod motor 5 will swing around the hinge shaft on the motor fixing seat 7 to a certain extent, thereby ensuring that the smoke baffle 3 can always move smoothly.

[0046] Note that the above merely describes preferred embodiments of the present application and the applied technical principles. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, and that various obvious changes, modifications and substitutions can be made without departing from the scope of the present application. Therefore, although the present application has been described in detail through the above embodiments, the present application is not limited to the above embodiments, and can include more other equivalent embodiments without departing from the concept of the present application, and the scope of the present application is determined by the scope of the claims.
