[0001] The present application relates to the technical field of household appliances, and particularly to a main machine assembly and a cooking machine. Background Art

[0002] With the increasing improvement of people's living standards, many different types of cooking machines have emerged on the market. Generally for safety convenience, two switches are usually set on the main machine assembly: a safety switch and a start switch.

[0003] Installing the start switch and the safety switch simultaneously ensures operation safety and avoids accidental start. However, setting the safety switch and the start switch simultaneously results in high costs and a complex internal structure.

[0004] Therefore, it is necessary to design a main machine assembly with a simple structure and low cost. Utility Model Content

[0005] The present application provides a main machine assembly and a cooking machine, which have a simple structure and low cost.

[0006] According to the first aspect of the embodiments of the present specification, a main machine assembly is provided, which includes:

[0007] A housing, in which a motor is installed;

[0008] An upper cover, installed on the housing;

[0010] A connecting rod, which is movably arranged relative to the housing. The connecting rod is assembled with a switch, the switch is correspondingly arranged with the button, and the switch is electrically connected to the motor;

[0011] When the connecting rod is pushed by force, the connecting rod drives the switch to move towards the button to a trigger position, so that when the button is pressed, the switch can be triggered to close, enabling the motor to start working. In this way, the present application cancels the separate safety switch. By assembling the connecting rod and the switch for starting the motor, and by means of the movement of the connecting rod, the switch is synchronously driven to move. Without the need to rely on other structures, the switch can be in the trigger position or the non-trigger position. Only when the switch is in the trigger position can the main machine assembly be started to achieve the safe start and stop of the main machine assembly. The structure is simple, effectively reducing costs and improving the market competitiveness of the product.

[0012] Further, the connecting rod is provided with an installation part, and the switch is assembled on the installation part; the installation part includes a base body, and buckle strips extending outward from the base body are provided at opposite ends of the base body, and buckle parts cooperating with the switch are provided at the ends of the buckle strips.

[0013] Further, the base further includes fixing columns, and the fixing columns and the buckle strip are located on the same side of the base; the switch is provided with mounting holes that cooperate with the fixing columns. In this way, the mounting position of the switch on the connecting rod can be further fixed.

[0014] Further, the main body assembly further includes an upper shock pad. The upper cover is provided with rib positions extending towards the motor, and the upper shock pad is clamped between the top of the motor and the rib positions. In this way, while the motor can be shock-absorbed, it can also play a role in heat insulation and flame retardancy. In addition, the motor is fixed above through the rib positions.

[0015] Further, the main body assembly further includes a lower shock pad. The bottom of the housing is provided with a positioning portion, and the lower shock pad is clamped between the bottom of the motor and the positioning portion. In this way, while the motor can be shock-absorbed, it can also play a role in heat insulation and flame retardancy. In addition, the motor is fixed above through the positioning portion.

[0016] Further, the upper cover is provided with an opening through which the switch passes. A pressing block protruding downward is provided on the button located above the opening; when the switch is in the trigger position, pressing the button can cause the pressing block to trigger the switch. In this way, the movement stroke of the button and the switch can be reduced through the pressing block.

[0017] Further, the upper cover is provided with a limiting portion extending towards the opening, and the connecting rod is correspondingly provided with a stopping portion. When in the trigger position, the limiting portion abuts against the stopping portion. In this way, the movement path of the connecting rod can be restricted, enabling the connecting rod to accurately move to the trigger position and improving the accuracy of the switch.

[0018] Further, a connecting rod hole is provided in the housing. The outer diameter of the upper end of the connecting rod is greater than the inner diameter of the connecting rod hole, and the lower end of the connecting rod is assembled in the connecting rod hole. In this way, the movement path of the connecting rod can be restricted, preventing the connecting rod from sliding out of the connecting rod hole.

[0019] Further, the upper cover is provided with a first snap, and the housing is provided with a second snap. By rotating the upper cover relative to the housing, the first snap and the second snap are snapped together. In this way, the upper cover and the housing are locked through the snaps, and the structure is stable.

[0020] Further, the button is provided with barbs, and the button is installed on the upper cover by hooking the barbs on the upper cover. In this way, it is ensured that the button and the upper cover do not separate, and the button is movably installed on the upper cover.

[0021] Further, the host assembly further includes a positioning post and an elastic member sleeved on the positioning post. Two ends of the elastic member respectively abut against the button and the upper cover. In this way, the up-and-down elastic movement of the button can be ensured, and deviation can be avoided.

[0022] According to the second aspect of the embodiments of the present specification, a cooking machine is provided, which includes the host assembly, a bowl cover, a cooking bowl assembly, and a stirring knife assembly described in the first aspect above.

[0033] Here, the technical solutions in the embodiments (or "embodiment modes") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0034] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and motion conditions between components in a specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be construed as indicating or implying relative importance.

[0035] Next, the embodiments of the present specification will be described in detail.

[0036] Referring to Figure 2 As shown, the present application discloses a main machine assembly 100, which includes a housing 10, an upper cover 20, a key 30, and a connecting rod 40. A motor 50 is installed inside the housing 10. The upper cover 20 is installed on the housing 10. The key 30 is installed on the upper cover 20. The connecting rod 40 is movably arranged relative to the housing 10, and a switch 60 is assembled on the connecting rod 40. The switch 60 is correspondingly arranged with the key 30, and the switch 60 is electrically connected to the motor 50.

[0037] When the connecting rod 40 is pushed under force, the connecting rod 40 drives the switch 60 to move towards the key 30 to a trigger position, so that the key 30 can trigger the switch 60 to close when it is pressed, enabling the motor 50 to start working. In this way, a separate safety switch is cancelled. By assembling the connecting rod 40 and the switch 60 for starting the motor, and by means of the movement of the connecting rod 40 to synchronously drive the switch 60 to move, the switch 60 can be in the trigger position or the non-trigger position without the need for other structures. When the switch 60 moves to the trigger position along with the connecting rod 40, it can be triggered to start the motor 50, thereby realizing the safe start and stop of the main machine assembly 100. The structure is simple, the cost is effectively reduced, and the market competitiveness of the product is improved.

[0038] In this embodiment, by using one switch 60 to realize the safe start and stop of the main machine assembly 100, there is no need to additionally set a safety switch for safety control, effectively reducing the cost and improving the market competitiveness of the product.

[0039] Reference Figure 3 and Figure 7 As shown, a mounting portion 41 is provided at one end of the connecting rod 40, the mounting portion 41 is provided at one end close to the button 30 and is integrally formed with the connecting rod 40, and the switch 60 is assembled on the mounting portion 41. In this way, the connecting rod 40 and the switch 60 move up or down as a whole, and no additional device for driving the switch 60 is required, and the structure is simple.

[0040] The mounting portion 41 includes a base 411, and buckle strips 412 extending outward from the base 411 are provided at opposite ends of the base 411, and a buckle portion 4121 is provided at the end of the buckle strip 412 to cooperate with the switch 60. In this way, the switch 60 can be assembled on the connecting rod 70, and the buckle portion 4121 can stabilize the installation position of the switch 60, thereby reducing the influence of the vibration of the motor 50 on the installation position of the switch 60.

[0041] The buckle portion 4121 is provided with an inclined surface, so that the switch 60 can be installed into the mounting portion 41 from the outside and guided by the inclined surface for installation. The opening size of the front end of the buckle strip 412 is smaller than the opening size of the rear end, and the size of the switch 60 is larger than the size of the front end of the buckle strip 412, and smaller than or equal to the size of the rear end of the buckle strip 412. In this way, when the switch 60 is installed, the buckle strip 412 needs to be opened. When the switch 60 is installed in place, the front end of the buckle strip 412 rebounds and locks, and is locked by the buckle portion 4121 to stabilize the installation position of the switch 60 on the mounting portion 41.

[0042] In addition to fixing the switch 60 by the above-mentioned mounting structure, this embodiment further includes a fixing column 413 extending toward one side, and the fixing column 413 and the buckle strip 412 are located on the same side of the base 411; the switch 60 is provided with a mounting hole 61 that matches the fixing column 413. In this way, the installation position of the switch 60 on the connecting rod 40 can be further fixed.

[0043] Reference Figures 2-4 As shown, the host assembly 100 further includes an upper shock-absorbing pad 71, and the upper cover 20 is provided with a rib 21 extending toward the motor 50, and the upper shock-absorbing pad 71 is clamped between the top of the motor 50 and the rib 21. In this way, the motor 50 can be damped and heat-insulated and flame-retardant.

[0044] The upper damping pad 71 is stepped, and the rib 21 abuts against the step of the upper damping pad 71. In this embodiment, the rib 21 is an annular hole, whose inner diameter is larger than the upper end of the motor 50 and is sleeved on the motor 50 to fix the upper end of the motor 50.

[0045] The main body assembly 100 further includes a lower shock pad 72. A positioning portion 11 is provided at the bottom of the housing 10. The lower shock pad 72 is clamped between the bottom of the motor 50 and the positioning portion 11. In this way, it can play a role in shock absorption of the motor 50 and also play a role in heat insulation and flame retardance. In addition, the motor 50 is fixed below through the positioning portion 11.

[0046] Referring Figures 3-6 As shown, the upper cover 20 is provided with an opening 22 for the switch 60 to pass through. A downwardly protruding pressing block 31 is provided on the button 30 above the opening 22; when the switch 60 is in the trigger position, pressing the button 30 can cause the pressing block 31 to trigger the switch 60. In this way, the movement stroke of the button 30 and the switch 60 can be reduced through the pressing block 31.

[0047] In order to prevent the upward movement path of the connecting rod 40 from being too large, when the operator does not press the button 30, the switch 60 on the connecting rod 40 directly abuts against the pressing block 31 and triggers the switch 60. Therefore, the upper cover 20 is provided with a limiting portion 23 extending towards the opening 22, and the connecting rod 40 is correspondingly provided with a stop portion 414. When in the trigger position, the limiting portion 23 abuts against the stop portion 414. In this way, the movement path of the connecting rod 40 can be restricted, so that the connecting rod 40 accurately moves to the trigger position, improving the accuracy of the switch of the main body assembly 100.

[0048] A connecting rod hole 12 is provided in the housing 10. The outer diameter of the upper end of the connecting rod 40 is greater than the inner diameter of the connecting rod hole 12, and the lower end of the connecting rod 40 is assembled in the connecting rod hole 12. In this way, the movement path of the connecting rod 40 can be restricted, so that the connecting rod 40 cannot slide out of the connecting rod hole 12.

[0049] The upper cover 20 is provided with a first snap 24, and the housing 10 is provided with a second snap 13. By rotating the upper cover 20 relative to the housing 10, the first snap 24 and the second snap 13 are snapped together. In this way, the upper cover 20 and the housing 10 are locked by the snaps, and the structure is stable. Among them, in order to improve the alignment accuracy of the first snap 24 and the second snap 13, in this embodiment, a ring-shaped protrusion is provided at the top of the housing 10, and a groove adapted to the ring-shaped protrusion is provided at the bottom of the corresponding upper cover 20 to ensure that the positions of the upper cover 20 and the housing 10 are aligned before rotational alignment.

[0050] The button 30 is provided with a barb 33, and the upper cover 20 is fastened by the barb 33 to ensure that the button 30 and the upper cover 20 do not come off, so that the button 30 is installed on the upper cover 20.

[0051] The main body assembly 100 further includes a positioning post 32 and an elastic member 80 sleeved on the positioning post 32. The two ends of the elastic member 80 respectively abut against the button 30 and the upper cover 20, and a receiving groove for positioning the elastic member 80 is also provided on the upper cover 20. Among them, the elastic member 80 can be a spring or an elastic rubber member, etc.

[0052] AsFigure 4 As shown, the elastic member 80 is normally extended, that is, when the button 30 is not pressed, the barb 33 abuts against the inner wall of the upper cover 20. As Figure 3 shown, when the button 30 is pressed and moves downward, the elastic member 80 is compressed, the barb 33 moves downward, and there is a gap between the barb 33 and the inner wall of the upper cover 20. In this way, the button 30 and the upper cover 20 achieve elastic contact through the elastic member 80 and the barb 33. At the same time, the elastic member 80 is sleeved on the positioning post 32, which can ensure the elastic up and down movement of the button 30 and avoid deviation.

[0053] Referring to Figure 1 shown, the present application also discloses a cooking machine. The cooking machine includes the above-mentioned main machine assembly 100, the bowl cover 200, the cooking bowl assembly 300 and the stirring knife assembly 400. The stirring knife assembly 400 is located inside the cooking bowl assembly 300, and the bowl cover 200 and the cooking bowl assembly 300 are covered.

[0054] The bowl cover 200 includes a communication hole 201 and an abutting portion 202 for pushing the connecting rod 40. The main machine assembly 100 is placed on the bowl cover 200, and the motor 50 is connected to the rotating shaft 401 of the stirring knife assembly 400 through the communication hole 201. In this way, by pushing the connecting rod 40 upward through the abutting portion 202, the switch 60 on the connecting rod 40 is synchronously driven to move upward. Furthermore, when the button 30 is pressed downward, the switch 60 can be triggered, so that the motor 50 starts to work. Thus, the motor 50 can drive the stirring knife assembly 400 to rotate to process food ingredients.

[0055] The switch 60 and the connecting rod 40 of the present application are assembled integrally and move upward integrally after being pushed by the abutting portion 202 of the bowl cover 200, so that the switch 60 reaches the trigger position. When the button 30 is pressed, the switch 60 is directly triggered and the motor 50 starts. Instead of the original design of two switches, while ensuring the safe start of the motor 50, the cost is saved and the production efficiency is improved.

[0056] In addition, relying on the snap-fit assembly of the upper cover 20 and the housing 10, the motor 50 in the middle is fixed up and down. An upper shock pad 71 is provided between the motor 50 and the upper cover 20, and a lower shock pad 72 is provided between the motor 50 and the housing 10, which can play a role in shock absorption of the motor 50 and also has the functions of heat insulation and flame retardancy. Instead of the original plastic motor bracket, the cost is saved and the assembly efficiency is improved.

[0057] The present application also discloses the assembly method of the host component 100, which is specifically as follows: First, install the lower shock pad 72 at the bottom of the motor 50 and insert it into the housing 10, so that the lower shock pad 72 is clamped between the bottom of the motor 50 and the positioning portion 11 of the housing 10; then align the fixing post 413 with the mounting hole 61 of the switch 60 and insert it, and position the switch 60 through the buckle 412 at the same time; then place the upper shock pad 71 on the top of the motor 50; then align the rib 21 of the upper cover 20 with the upper shock pad 71 and rotate and lock the upper cover 20 and the housing 10 through the first snap 24 and the second snap 13; then place the elastic member 80 on the upper cover 20; finally, the key 30 is snapped into the upper cover 20 through the barb 33, and the elastic member 80 is positioned through the positioning post 32 on the key 30 to complete the assembly.

[0058] The present application also discloses the working method of the host component 100, and the following specifically shows the process of starting the host component 100: First, assemble the host component 100 to the bowl cover 200, and the abutting portion 202 on the bowl cover 200 pushes the connecting rod 40 and the switch 60 to move up integrally; then manually press the key 30, and the pressing block 31 on the key 30 moves down synchronously and presses the switch 60 to control the motor 50 to start working. The motor 50 is connected to the rotating shaft 401 of the stirring blade assembly 400 through the communication hole 201 of the bowl cover 200, so as to drive the stirring blade assembly 400 to rotate.

[0059] The present application also shows the disconnection process of the host component 100: First, release the key 30, and the key 30 is reset under the elastic action of the elastic member 80 to push the key 30 to move up and stop working; finally, the host component 100 leaves the bowl cover 200, and the connecting rod 40 and the switch 60 move down naturally integrally. The switch 60 is in the non-trigger position, and pressing the key 30 cannot trigger the switch 60, so the motor 50 cannot be started.

[0060] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
