Description

A food processing machine Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a food processing machine. Background Technology

[0002] In existing food processors, users control the machine by pressing buttons on the control panel. These buttons, such as the membrane buttons disclosed in CN201621082523.X, involve touching a curved touch area to perform touch operations. However, this design leads to fatigue and damage of the membrane buttons after repeated pressing, resulting in poor reliability.

[0003] There are also spring-loaded button structures, such as the one disclosed in CN2010723400.5. In this structure, the rear end of the spring is fixed to the control board, and during installation, the spring is compressed against the inner wall of the housing. The corresponding function is activated by inductive sensing on the outside of the housing. Because the spring needs to be compressed during installation, and a dedicated positioning structure is required to guide the spring and prevent misalignment, the spring-loaded touch-sensing installation structure disclosed in the aforementioned patents is relatively complex and cumbersome, and has a high manufacturing cost. Summary of the Invention

[0004] This application provides a food processing machine to solve the problems of poor reliability of the control panel buttons in existing food processing machines due to multiple triggering, cumbersome installation, and high manufacturing cost.

[0005] This application provides a food processing machine, including a housing and a control panel disposed within the housing. The food processing machine also includes an interface operation area disposed on the housing. A sensor sticker covering the interface operation area is disposed on the inner side of the housing. A wire harness electrically connected to the control panel is disposed on the sensor sticker. In the power-on state, the operation function on the sensor sticker can be triggered remotely from the outside of the interface operation area.

[0006] Compared to existing technologies that require direct contact with external force to press the buttons on the control panel to control the food processor, this application uses a sensor sticker covering the interface operation area on the inside of the housing. By triggering the operation function on the sensor sticker in the air, the food processor can be controlled without physical contact. This avoids the fatigue damage caused by repeated button pressing in existing technologies. Furthermore, the adhesive covering method of the sensor sticker makes the installation of the food processor's control structure simpler and more convenient, effectively solving the problems of poor reliability, cumbersome installation, and high manufacturing cost of the buttons on the control panel of existing food processors.

[0007] As a preferred technical solution, the food processing machine includes a bracket installed inside the housing and corresponding to the interface operation area, and the sensing surface is attached to the bracket and faces the interface operation area.

[0008] By installing a bracket, which serves as a carrier for the sensor patch, the installation stability of the sensor patch is improved.

[0009] As a preferred technical solution, the control panel is mounted on the side of the bracket away from the sensing surface.

[0010] Furthermore, the control panel is placed on the other side of the bracket, which not only achieves fixed installation of the control panel, but also facilitates the electrical connection between the wiring harness of the sensing surface and the control panel.

[0011] As a preferred technical solution, the inner wall of the housing is provided with a plurality of first studs arranged around the interface operation area along the circumferential direction, and the bracket is provided with a first through hole corresponding to the first stud. Screws pass through the first through hole and are fixed to the first stud to fix the bracket to the housing.

[0012] By setting several first studs around the interface operation area, the bracket can be installed on the housing, and the sensing surface on the bracket can be precisely aligned with the interface operation area, making the user's sensing and control more accurate.

[0013] As a preferred technical solution, the sensing surface is attached to the inner surface of the interface operation area located inside the housing.

[0014] As another implementation, the sensor sticker is directly attached to the inner surface of the interface operation area located inside the housing, which simplifies the installation structure of the sensor sticker.

[0015] As a preferred technical solution, the housing includes an outer shell and a panel separately mounted on the outer shell. The interface operation area is formed on the panel. The outer shell is provided with mounting holes, and the panel is sealed and mounted at the mounting holes.

[0016] By setting up a panel, an interface operation area is formed on the panel. Then, the panel is sealed and installed on the mounting hole of the housing, so that the sensing surface and the panel form a component, which is convenient for assembly.

[0017] As a preferred technical solution, a sealing groove is provided around the outer wall edge of the panel, and a sealing ring is provided in the sealing groove. The panel is inserted into the mounting hole from the inside of the outer shell, and the sealing ring is pressed against the inner wall of the outer shell.

[0018] As a preferred technical solution, the sensing surface is provided with a wire harness strip, the wire harness of the sensing surface is integrated on the wire harness strip, and the end of the wire harness strip is integrally formed with a plug-in piece that is electrically connected to the wire harness. The control panel is provided with a plug-in terminal, and the plug-in piece is plugged into the plug-in terminal.

[0019] The wire harness of the sensor patch is integrated together by using a wire harness tape, and inserts are provided at the ends of the wire harness tape. This improves the integration of the sensor patch and makes it easier to manufacture. It also facilitates the assembly of the sensor patch and the control board.

[0020] As a preferred technical solution, the food processing machine includes a light-transmitting bracket with multiple light-transmitting holes, a plurality of sensing elements on the sensing surface, and a plurality of surface-mount lights on the control panel, with the surface-mount lights and sensing elements respectively arranged on both sides of the light-transmitting holes.

[0021] As a preferred technical solution, the food processing machine includes an inner cup, and the housing is a cup body outer shell fitted onto the outside of the inner cup;

[0022] Alternatively, the food processing machine includes a base and a cup body detachably mounted on the base, the housing forming the outer wall of the base. Attached Figure Description

Detailed Implementation

[0040] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0042] Example 1

[0043] In existing food processing machines, users control them by pressing membrane buttons or spring buttons. However, membrane buttons suffer from fatigue damage due to repeated pressing of the touch area, resulting in poor reliability; while spring buttons have a more complex installation structure, a cumbersome installation process, and higher manufacturing costs.

[0044] To address the above-mentioned problems, this application provides a food processing machine, as shown in Figures 1 and 2. Figure 1 is a three-dimensional structural diagram of the food processing machine described in this application embodiment.

[0045] Figure 2 is a schematic diagram of the structure of the food processor display sensor patch 4 and control panel 2 described in this embodiment of the application. The food processor includes a housing 1, within which are arranged structures such as an inner cup, a motor, and a power board. A control panel 2 is also located within the housing 1. An interface operation area 3 is also provided on the housing 1. A sensor patch 4, covering the interface operation area 3, is disposed on the inner side of the housing 1. The sensor patch 4 has a wiring harness electrically connected to the control panel 2. When the food processor is powered on, the user can remotely trigger the operation function on the sensor patch 4. The sensor patch 4 generates a signal, which is transmitted to the control panel 2 via the wiring harness, thereby enabling control of the corresponding function of the food processor through the control panel 2.

[0046] It is understood that the aforementioned sensing surface 4 can consist of two thin films sandwiching several sensing elements 41 (such as electrodes, which form a non-contact capacitive structure with the human body). Each sensing element 41 is connected to the control panel 2 via a wire harness. When the user's finger approaches the sensing element 41, the capacitance of the sensing element 41 changes, thereby generating a signal, which is transmitted to the control panel 2 via the wire harness. The control panel 2 implements corresponding control based on the different signals received, so as to control different functions of the food processing machine.

[0047] Compared to the existing technology that requires direct contact with external force to press the buttons on the control panel to control the food processor, this embodiment achieves control of the food processor by triggering the operation function on the induction surface 4 without physical contact. This avoids the fatigue damage caused by repeated button pressing in the existing technology. Furthermore, the induction surface simplifies the installation of the food processor's control structure and makes assembly more convenient by using an adhesive covering method. This effectively solves the problems of poor reliability due to repeated triggering of buttons on the control panel 12 of the existing food processor, as well as the cumbersome installation and high manufacturing cost.

[0048] As shown in Figure 3, which is a structural schematic diagram of the sensing faceplate 4 according to an embodiment of this application, the sensing faceplate 4 in this embodiment is provided with a wire harness. The wire harnesses of each sensing part 41 on the sensing faceplate 4 are integrated on the wire harness, and the end of the wire harness is integrally formed with a plug 42 that is electrically connected to the wire harness. Correspondingly, as shown in Figure 4, a plug terminal 21 is provided on the control panel 2. The plug 42 is plugged into the plug terminal 21 to realize the electrical connection between the sensing faceplate 4 and the control panel 2. In this embodiment, the wire harness of the sensing faceplate 4 is integrated together by the wire harness, and the plug 42 is provided at the end of the wire harness, which makes the integration of the sensing faceplate 4 better and easier to manufacture. Moreover, the connection method between the plug 42 and the plug terminal 21 also facilitates the assembly of the sensing faceplate 4 and the control panel 2.

[0049] It should be noted that in this embodiment, the plug-in terminal 21 and the sensing surface 4 are respectively located on both sides of the control panel 2. The control panel 2 is also provided with a through hole 22, through which the insert 42 passes and is plugged into the plug-in terminal 21.

[0050] In this embodiment, the interface operation area 3 can be directly integrally formed on the housing 1 (the dotted line in Figure 1 shows the interface operation area 3). At this time, the sensing surface sticker 4 is directly attached to the inner surface of the interface operation area 3 located on the inner side of the housing 1. This structure simplifies the installation structure of the sensing surface sticker 4.

[0051] It is understandable that the control panel 2 is installed inside the housing 1. It can be installed facing the sensing surface 4, or a suitable installation position can be selected according to the size of the internal space of the housing 1, as long as the electrical connection between the control panel 2 and the sensing surface 4 is met.

[0052] Preferably, in this embodiment, the food processing machine can also be provided with a light-transmitting bracket (not shown in the figure), which has multiple light-transmitting holes. These light-transmitting holes correspond one-to-one with the sensing elements 41 on the sensing surface 4. As shown in Figure 5, the control panel 2 has multiple LED patches 23, which are positioned on both sides of the light-transmitting holes, corresponding one-to-one with the sensing elements 41. The sensing surface 4 can also be provided with luminous functional patterns, such as operation icons and digital icons. The operation icons can correspond to each sensing element 41. When the LED patch 23 illuminates, the operation icon and digital icon will be lit, allowing the user to identify the operation.

[0053] It should be noted that the interface operation area 3 in this embodiment is a transparent or semi-transparent light-transmitting structure so that light can be displayed through the interface operation area 3.

[0054] In this embodiment, the food processing machine includes an inner cup, and the housing 1 is a cup shell fitted onto the outside of the inner cup. The interface operation area 3 is directly disposed on the cup shell. Of course, it can be understood that the food processing machine may also include a base and a cup body detachably mounted on the base, with the housing 1 forming the outer wall of the base, in which case the interface operation area 3 is disposed on the outer wall of the base.

[0055] Example 2

[0056] This embodiment provides a food processor, which differs from Embodiment 1 in that it adds a panel 12. Specifically, Figure 6 is a three-dimensional structural diagram of the food processor described in this embodiment; Figure 7 is a structural diagram of the display sensor patch 4, control panel 2, and panel 12 of the food processor described in this embodiment. As shown in Figures 6 and 7, the housing 1 of the food processor in this embodiment includes an outer shell 11 and a panel 12 separately mounted on the outer shell 11. A mounting hole 111 is provided on the outer shell 11, and the panel 12 is sealed and mounted at the mounting hole 111. An interface operation area 3 is provided on the panel 12. The sensor patch 4 is attached to the panel 12 and electrically connected to the control panel 2. When the food processor is powered on, the user can remotely trigger the operation function on the sensor patch 4. The sensor patch 4 generates a signal and transmits it to the control panel 2 through a wiring harness, thereby controlling the corresponding function of the food processor through the control panel 2.

[0057] In this embodiment, by setting the aforementioned panel 12 and forming an interface operation area 3 on the panel 12, and then sealing the panel 12 at the mounting hole 111 of the housing 1, the sensing surface 4 and the panel 12 form an integral component, facilitating assembly. Furthermore, using the panel 12 as a carrier for the interface operation area 3 also facilitates processing. Moreover, it allows for diverse appearances of the food processing machine; for example, the panel 12 can be made of a different material or color than the housing 11, resulting in a more aesthetically pleasing overall appearance.

[0058] As shown in Figure 8, in this embodiment, a sealing groove 121 is provided around the outer edge of the panel 12, and a sealing ring 122 is provided in the sealing groove 121. The panel 12 is inserted into the mounting hole 111 from the inside of the outer shell 11, and the sealing ring 122 is pressed tightly against the inner wall of the outer shell 11, thereby achieving a sealed installation between the panel 12 and the outer shell 11 and preventing dirt from entering the outer shell 11. In addition, in this embodiment, the panel 12 is installed in the mounting hole 111 from the inside out, which also facilitates the assembly of the panel 12.

[0059] The outer surface of the panel 12 is flush with the outer surface of the outer casing 11, which makes the overall appearance of the food processing machine more aesthetically pleasing.

[0060] In this embodiment, the panel 12 can be fixed to the mounting hole 111 by adhesive, or by setting studs on the outer shell 11, with holes circumferentially provided on the panel 12, and screws threaded through the holes to the studs to achieve installation of the panel 12 and the outer shell 11. Alternatively, it can be fixed to the mounting hole 111 of the outer shell 11 by snap-fit. This embodiment does not specifically limit the installation method of the panel 12.

[0061] Other components in this embodiment, such as housing 1, control panel 2, and sensor surface 4, have the same structural principles as in embodiment 1. Furthermore, this embodiment can also be equipped with a light-transmitting bracket, the structural principle of which is also the same as in embodiment 1, and will not be described again.

[0062] Example 3

[0063] This embodiment provides a food processing machine, which differs from Embodiment 2 in that the food processing machine in this embodiment adds a "support 5" structure. Specifically, Figure 9 is a schematic diagram of the structure of the display sensor surface 4, control panel 2, panel 12, and support 5 of the food processing machine described in this embodiment; Figure 10 is a cross-sectional view of the food processing machine described in this embodiment.

[0064] Figure 11 is an assembly diagram of the outer shell, control panel, and support of the food processor according to an embodiment of this application; Figure 12 is an assembly cross-sectional view of the panel 12, sensor sticker 4, and support 5 of the food processor according to an embodiment of this application. In this embodiment, as shown in Figures 9-12, the food processor includes a shell 1, a control panel 2, a sensor sticker 4, a panel 12, and a support 5. The control panel 2 and the support 5 are both disposed inside the shell 1. The panel 12 is partially installed at the mounting hole 111 of the shell 1. The interface operation area 3 is disposed on the panel 12 and is correspondingly disposed on the support 5. The sensor sticker 4 is attached to the support 5 and is located between the support 5 and the panel 12.

[0065] Optionally, in this embodiment, the bracket 5 is provided with a plurality of first through holes 51 along the circumference, and the inner wall of the housing 1 is provided with a plurality of first studs surrounding the interface operation area 3 along the circumference. That is, the aforementioned first studs can be provided on the outer periphery of the mounting holes 111 of the housing 1. The first studs are provided in a one-to-one correspondence with the aforementioned first through holes 51, and screws pass through the first through holes 51 and are fixed to the first studs to fix the bracket 5 to the housing 1. This structure enables the bracket 5 to be installed on the housing 1 while also ensuring that the sensing surface 4 on the bracket 5 is precisely aligned with the interface operation area 3, making the user's sensing and control more precise.

[0066] In this embodiment, as shown in FIG12, a space for accommodating the sensing faceplate 4 is formed between the bracket 5 and the panel 12. For example, the panel 12 protrudes outward from the housing 1 to form a groove, and the bracket 5 correspondingly forms an outwardly protruding protrusion. The sensing faceplate 4 is attached to the outer surface of the protrusion, and then the protrusion is embedded in the groove. Through this structural arrangement, the bracket 5 serves as a carrier for the sensing faceplate 4, thereby improving the installation stability of the sensing faceplate 4.

[0067] Referring to Figure 13, the bracket 5 is provided with a light-transmitting hole 52, and the light-transmitting hole 52 corresponds one-to-one with the sensing part 41 on the sensing surface 4. When the food processing machine is powered on, the control panel 2 controls the patch light 23 to emit light, and the light shines through the light-transmitting hole 52 onto the corresponding sensing part 41, so that the operation icon on the sensing part 41 is lit up so that the user can identify the operation.

[0068] Furthermore, in this embodiment, the control panel 2 is preferably mounted on the bracket 5, and mounted on the side of the bracket 5 away from the sensing surface 4. By setting the control panel 2 on the other side of the bracket 5, the control panel 2 is fixedly mounted, and the electrical connection between the wiring harness of the sensing surface 4 and the control panel 2 is also facilitated.

[0069] For example, a positioning hole and a second through hole can be provided on the control panel 2. A positioning post 53 and a first stud 54 are provided on the side of the bracket 5 away from the sensing surface 4. The positioning post 53 is inserted into the positioning hole, and the screw passes through the second through hole and is threaded to the first stud 54 to fix the control panel 2 to the bracket 5.

[0070] Other structural principles of this embodiment, such as housing 1, control panel 2, and sensor surface 4, are the same as those of Embodiment 1 and will not be described again.

[0071] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0072] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
