[0043] like Figures 1 to 6 As shown, the present application provides a food processing machine with optimized structure, including a main machine 10 and a cup body assembly installed on the main machine 10, the main machine 10 includes a casing 11 and an inner cylinder 12 arranged in the casing 11, the inner cylinder 12 is provided with a notch 121 penetrating in the radial direction, a transparent visual window 13 is installed at the notch 121 to close the notch 121, the casing 11 is provided with a visual part corresponding to the visual window 13, the cup body assembly includes a glass cup, and the glass cup is installed in the inner cylinder 12.

[0044] The food processor of the present application is suitable for the model in which the main unit 10 fully wraps the cup body component (with a crushing chamber formed inside), and the main unit 10 can fully wrap the glass cup in the circumferential direction and the axial direction, which is conducive to reducing the crushing noise transmitted to the outside and improving the noise reduction performance of the product. Of course, the solution in which the cup body component is partially exposed in the axial direction is also included in the protection scope of the present application. In this case, the noise reduction effect can be controlled by reducing the exposed size, or, in some solutions, a soundproof cover can be set for the exposed part to improve the noise reduction effect.

[0045] Specifically, the casing 11 and the inner cylinder 12 form a double-layer structure. The casing 11 and the inner cylinder 12 can be an integral structure or a split structure. When the casing 11 and the inner cylinder 12 are a split structure, the inner cylinder 12 can be taken out separately to facilitate the installation of the visual window 13. At the same time, the integral part formed by the visual window 13 and the inner cylinder 12 is also convenient for installation with the casing 11.

[0046] like Figure 6 As shown, when the casing 11 and the inner cylinder 12 are a split structure, an opening 111 is provided on the top of the casing 11, a mounting portion 112 is provided on the outer edge of the opening 111, the mounting portion 112 is provided with a mounting hole, and a screw column 122 is provided on the top of the inner cylinder 12. After the inner cylinder 12 is inserted into the casing 11, screws can be used to fix it at the position of the mounting hole and the screw column 122 to achieve the installation of the inner cylinder 12.

[0047] As a preferred embodiment of the present application, the visible window 13 includes a transparent window body 131 and a first window frame 132 surrounding the edge of the window body 131, and the inner tube 12 is provided with a second window frame 123 surrounding the notch 121 and protruding outward, and the first window frame 132 is embedded in the inner side of the second window frame 123.

[0048] Specifically, Figure 3 and Figure 4 As shown, the window 131 is arranged in the longitudinal direction to close the gap 121, and the first window frame 132 provides conditions for the installation of the visible window 13. The window 131 can be made of glass or a transparent plastic part, for example. The material and transparency of the first window frame 132 are not required, for example, the first window frame 132 and the window 131 can be an integrated transparent part. The second window frame 123 can be a U-shaped structure or a rectangular structure.

[0049] Furthermore, the front end face of the first window frame 132 is provided with a radially outwardly protruding rib 133, and the rib 133 is provided with a first mounting hole 134. The outer wall of the second window frame 123 is provided with a first mounting column 124 corresponding to the first mounting hole 134, and the first mounting hole 134 and the first mounting column 124 are fixedly connected by a fastener 14.

[0050] like Figure 4 As shown, the fastener 14 is, for example, a screw, and the first mounting column 124 is a screw column. Using screws to fix the viewing window 13 can improve its installation firmness. The ribs 133 can be arranged in one circle or in only two places (using at least two screws to ensure effective installation), such as Figure 4 As shown, two first mounting holes 134 are provided at two opposite sides of the first window frame 132 , and the corresponding second window frame 123 is provided with two first mounting posts 124 , so that the viewing window 13 can be stably installed.

[0051] As a preferred embodiment of the present application, the inner wall surface of the viewing window 13 and the inner wall surface of the inner tube 12 are combined to form a continuous circumferential surface.

[0052] like Figure 4 As shown, the visual window 13 includes a transparent window 131, which adopts a curved surface structure. The inner cylinder 12 is cylindrical, and the curvature formed by the window 131 is just adapted to the curvature at the notch 121, so that the window 131 and the inner cylinder 12 can enclose a continuous circumferential surface. On the one hand, the inner cylinder 12 can have sufficient space for placing cups, which can avoid interference with the visual window 13 when placing or taking cups. On the other hand, the window 131 is an outward convex surface on the outside, which can increase the viewing angle and wide viewing angle, and can increase the user's visual range and improve the visualization effect. Further preferably, the visual window is set in a trumpet shape, which can further expand the visual range.

[0053] As a preferred embodiment of the present application, the visible window 13 includes a transparent window body 131 and a first window frame 132 surrounding the edge of the window body 131 , the first window frame 132 is plugged into the notch 121 and a sealing ring 15 is provided therebetween.

[0054] Since there is a fitting gap between the first window frame 132 and the notch 121, the sealing installation of the viewing window 13 can be achieved by arranging the sealing ring 15, so as to prevent the steam from overflowing from the crushing chamber during the operation of the machine from flowing into the space between the casing 11 and the inner cylinder 12 through the fitting gap, causing the high-temperature steam to increase the temperature of the casing 11, and the service life of the casing 11 may be affected by the high temperature for a long time; further, the sealing of the fitting gap can also prevent the crushing noise from being transmitted from this position, so as to optimize the noise reduction effect.

[0055] In one embodiment, Figure 4 As described above, the sealing ring 15 may be sleeved on the first window frame 132 ; or, in other embodiments, a second window frame 123 is provided at the notch 121 , and the sealing ring 15 may be provided on the inner wall of the second window frame 123 , which is not limited in the present application.

[0056] As a preferred embodiment of the present application, an isolation cavity 16 is formed between the housing 11 and the inner cylinder 12 , and the host 10 is provided with a light guide tube 17 , which is arranged corresponding to the visible window 13 , and the light guide tube 17 extends radially and covers the radial space of the isolation cavity 16 .

[0057] like Figure 2As shown, a circumferential isolation chamber 16 is formed between the housing 11 and the inner cylinder 12 in the radial direction. The isolation chamber 16 can not only enhance the sound insulation effect and effectively prevent the crushing noise from being transmitted, but also enhance the heat preservation effect of the cup body, and prevent the heat of the cup body from being transferred to the operation panel on the front side of the housing 11, which can comprehensively improve the performance of the machine. In the case of an isolation chamber 16, in order to prevent the user from seeing the inside of the isolation chamber 16 when viewing the crushing chamber through the visual window 13, the present application provides a light guide tube 17, which can prevent the light path in the isolation chamber 16 from propagating outward, can effectively block light, and enhance the user's visual experience.

[0058] In one embodiment, Figure 5 As shown, the visible window 13 is an integrated transparent part, and the visible window 13 includes a window body 131 and a peripheral edge 135 protruding outward from the window body 131, and the light guide tube 17 is arranged on the inner side of the peripheral edge 135. In this embodiment, the light guide tube 17 is installed in a set manner, and the installation is firm. The light guide tube 17 can be installed to the visible window 13 first and then the two are installed to the inner tube 12 together, or the light guide tube 17 can be installed after the visible window 13 is installed to the inner tube 12. Both methods are possible and easy to operate. The peripheral edge 135 has a large length in the radial direction. For example, the peripheral edge 135 can cover the radial space of the isolation cavity 16 in the radial direction, and the light guide tube 17 can be completely inserted into the peripheral edge 135, which can make the appearance more concise.

[0059] In another embodiment, Figure 2 and Figure 4 As shown, the light guide tube 17 abuts against the front end surface of the viewing window 13. In this embodiment, the first window frame 132 of the viewing window 13 has a smaller radial dimension, and the light guide tube 17 can be arranged outside the viewing window 13. The light guide tube 17 can cover most of the radial space of the isolation cavity 16, which can also improve the visual effect of the user viewing the pulverizing cavity.

[0060] The light guide tube 17 is a ring-shaped member, and the peripheral wall of the light guide tube 17 is made of an opaque material to effectively block light.

[0061] Furthermore, in a preferred embodiment, the host 10 further includes a display panel 18 mounted on the housing 11 , and the display panel 18 abuts against an end of the light guide tube 17 to sandwich the light guide tube 17 between the display panel 18 and the visible window 13 .

[0062] like Figure 2As shown, in the scheme where the light guide tube 17 is in contact with the visual window 13, the light guide tube 17 and the visual window 13 can be pressed inwardly by the display panel 18 in sequence by the display panel 18, which can improve the reliability and compactness of the installation of the structural parts as a whole. In addition to the clamping function of the display panel 18 and the visual window 13, in this embodiment, the housing 11 is provided with an axial limiting structure so that the top and bottom of the light guide tube 17 are limited by the axial limiting structure to ensure the stability of the light guide tube 17.

[0063] In the scheme where the light guide tube 17 is sleeved with the visual window 13, when the front end of the light guide tube 17 extends out of the surrounding edge 135, the light guide tube 17 is still sandwiched between the display panel 18 and the visual window 13. Alternatively, when the light guide tube 17 is completely surrounded by the surrounding edge 135, the display panel 18 can abut against the end of the visual window 13.

[0064] like Figure 1 As shown, a visible area 19 is formed in the area of ​​the visible window 13 on the front side of the housing 11, and an operating area 20 is provided below the visible area 19. The operating area 20 is usually equipped with a control panel assembly (including a control panel, a liquid crystal screen, etc.). Preferably, the display panel 18 can cover the visible area 19 and the operating area 20 as a whole, which is conducive to the simplicity and beauty of the overall appearance of the host 10. The display panel 18 can be a transparent piece, or the part of the display panel 18 corresponding to the visible area 19 is set to be transparent.

[0065] On the basis of the above scheme, further, the function of the visible part on the housing 11 is to provide conditions for the user to see the visible window 13 through the housing 11. In one embodiment, the housing 11 is provided with a mounting port 21 corresponding to the visible window 13 to form a visible part. Specifically, the visible window 13 can be located on the inner side of the mounting port 21, and a transparent window plate is further installed at the mounting port 21, which is convenient for the user to view the visible window 13 through the window plate (and then view the crushing chamber through the visible window 13), and can also be used to prevent the crushing noise from being transmitted. Alternatively, when the window frame of the visible window 13 is long in radial direction, the window frame can extend through the mounting port 21. Alternatively, in the scheme with a light guide tube 17, the light guide tube 17 can be installed at the mounting port 21.

[0066] In another embodiment, the housing 11 is provided with a transparent window panel corresponding to the visible window 13 to form a visible portion. Specifically, the window panel and the housing 11 can form an integrated structure, and the housing 11 is only set to be transparent at the position of the window panel so that the user can view the visible window 13 through the window panel.
