Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an air duct component, a base component and a food processor. Background Art

[0002] At present, food processors such as wall breaking machines, soy milk machines, and juicers are very popular among users. Food processors use motors to drive blades to beat food to cook food. The motor that drives the blades to beat food will rotate at a speed of up to tens of thousands of revolutions during operation. The high-speed operation of the motor will generate a lot of heat. In order to dissipate the heat of the motor, a fan will be set at the end of the motor away from the output shaft. At the same time, an air duct component that guides the direction of the wind will be set on the base of the food processor to facilitate the heat dissipation of the motor.

[0003] When assembling the air duct assembly in the prior art, usually only the upper air duct and the lower air duct are stacked together and then fixed with screws. However, if the upper air duct and the lower air duct are misaligned when stacked, fixing them with screws will cause air leakage in the air duct assembly, and the incoming air may be discharged from the air outlet without passing through the motor to dissipate the heat of the motor, which affects the heat dissipation effect of the whole machine and may affect the normal use of the motor in severe cases.

[0071] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0072] In the related art, when assembling the air duct assembly of a food processor, the upper air duct and the lower air duct are usually stacked together and then fixed with screws. Since there is no positioning structure when stacking, or only positioning is performed by setting partial positioning ribs along the circumferential direction at the connection between the upper air duct and the lower air duct, the assembly of the two parts of the upper air duct and the lower air duct will be inaccurately positioned and misaligned. Fixing with screws will cause air leakage in the air duct assembly, and the incoming air may be discharged from the air outlet without passing through the motor to dissipate the heat of the motor, which will affect the heat dissipation effect of the whole machine and may affect the normal use of the motor in severe cases.

[0073] To this end, the present invention provides an air duct assembly, a base assembly and a food processor for a food processor, so as to solve the problem that the upper air duct and the lower air duct are misaligned during assembly, thereby affecting the heat dissipation effect.

[0074] Combine the following Figures 1 to 11 , describing an embodiment of the present invention.

[0075] like Figure 1-Figure 4 As shown, according to an embodiment of the present invention, on the one hand, an air duct assembly of a food processor is provided, including: a first cover plate 2, at least one first positioning structure 201 is provided on the circumference of the first cover plate 2, at least one third positioning structure 202 is provided in the middle of the first cover plate 2, and a first air duct 203 is provided on the first cover plate 2; a second cover plate 3, the second cover plate 3 is connected to the first cover plate 2, a second air duct 303 is provided on the second cover plate 3, and the second air duct 303 is connected to the first air duct 203; at least one second positioning structure 301 is provided on the circumference of the second cover plate 3, the second positioning structure 301 is matched and connected with the first positioning structure 201, and is suitable for positioning the first cover plate 2 and the second cover plate 3 along the circumferential direction; at least one fourth positioning structure 3071 is provided in the middle of the second cover plate 3, the fourth positioning structure 3071 is matched and connected with the third positioning structure 202, and is suitable for positioning the middle of the first cover plate 2 and the second cover plate 3.

[0076] By respectively arranging the first and second air ducts 203 and 303 that are connected on the first cover plate 2 and the second cover plate 3, the circulation of wind in the air duct assembly can be ensured; by arranging the first positioning structure 201 and the second positioning structure 301 that are matched and connected in the circumferential direction of the first cover plate 2 and the second cover plate 3, the first cover plate 2 and the second cover plate 3 can be positioned in the circumferential direction to prevent the first cover plate 2 and the second cover plate 3 from being misplaced outward; by arranging the third positioning structure 202 and the fourth positioning structure 3071 that are matched and connected in the middle part of the first cover plate 2 and the second cover plate 3, it can be suitable for positioning the middle part of the first cover plate 2 and the second cover plate 3 to prevent the first cover plate 2 and the second cover plate 3 from being misplaced toward the middle, thereby ensuring the installation accuracy of the first cover plate 2 and the second cover plate 3, and further ensuring the installation accuracy of the first air duct 203 and the second air duct 303, and ensuring the ventilation and heat dissipation effect of the air duct assembly.

[0077] In one embodiment, the first positioning structure 201 and the second positioning structure 301 are provided in plurality, and the plurality of first positioning structures 201 are arranged at intervals on the first cover plate 2, and the plurality of second positioning structures 301 are arranged at intervals on the second cover plate 3. By providing the first positioning structure 201 and the second positioning structure 301 in plurality, the plurality of parts of the first cover plate 2 and the second cover plate 3 can be better positioned, the installation accuracy of each part of the first cover plate 2 and the second cover plate 3 is ensured, and the misalignment of the first cover plate 2 and the second cover plate 3 is prevented. Of course, in order to achieve a better positioning effect, the plurality of first positioning structures 201 should be arranged at intervals along the circumference of the first cover plate 2, and occupy the entire circumferential space of the first cover plate 2 as much as possible, and the plurality of second positioning structures 301 should be arranged at intervals along the circumference of the second cover plate 3, and occupy the entire circumferential space of the second cover plate 3 as much as possible. As a convertible embodiment, it is also possible that the first positioning structure 201 and the second positioning structure 301 are provided in one each.

[0078] Specifically, Figure 3 and Figure 4 As shown, there are three first positioning structures 201 and three second positioning structures 301, respectively. The three first positioning structures 201 are respectively arranged at the two ends of the first cover plate 2 along the circumferential direction, and the three second positioning structures 301 are respectively arranged at the two ends of the second cover plate 3 along the circumferential direction. That is, the three first positioning structures 201 are arranged in a triangular shape at the two ends of the first cover plate 2, and the three second positioning structures 301 are arranged in a triangular shape at the two ends of the second cover plate 3. By setting the number of first positioning structures 201 and second positioning structures 301 to three, respectively, and the three first positioning structures 201 and second positioning structures 301 are respectively arranged at the two ends of the first cover plate 2 and the second cover plate 3 along the circumferential direction, the number of positioning structures is reduced while the positioning of the first cover plate 2 and the second cover plate 3 along the circumferential direction can be ensured, thereby reducing the cost. As a convertible embodiment, it is also possible that there are two first positioning structures 201 and second positioning structures 301, respectively, and the two first positioning structures 201 and second positioning structures 301 are respectively arranged at the two ends of the first cover plate 2 and the second cover plate 3; or, there are more first positioning structures 201 and second positioning structures 301, respectively.

Specifically, the blocking structure 307 is a panel.

[0080] The second cover plate 3 is provided with a second installation space 302, which is provided on a side of the enclosure structure 307 away from the third through hole 304, and the first mainboard of the food processor is suitable for installation in the second installation space 302.

By providing the first installation space 210 on the first cover plate 2 and providing a plurality of avoidance portions 211 on the side of the second through hole 204 away from the enclosure structure 307, the installation of the second main board in the first installation space 210 can be ensured, and the structure is more compact.

By setting the positioning structure in the form of a positioning hole and a positioning column matching, and a positioning rib and a positioning groove matching, the positioning structure can realize the positioning function while having a relatively simple structure. As a convertible implementation, it is also possible that the first positioning structure 201 is a positioning column, the second positioning structure 301 is a positioning hole; the third positioning structure 202 is a positioning groove, and the fourth positioning structure 3071 is a positioning rib.

[0084] Among them, one third positioning structure 202 is set, and one fourth positioning structure 3071 is set. Of course, more third positioning structures 202 and fourth positioning structures 3071 can be set according to actual needs, and no excessive restrictions are made here.

[0085] After the first cover plate 2 and the second cover plate 3 are precisely positioned, the first cover plate 2 and the second cover plate 3 can also be pre-fixed. Specifically, two first fixing structures 205 can be provided on the first cover plate 2, and two second fixing structures 3051 that are matched and connected with the first fixing structures 205 can be provided on the second cover plate 3. By respectively providing the first fixing structure 205 and the second fixing structure 3051 on the first cover plate 2 and the second cover plate 3, the first cover plate 2 and the second cover plate 3 can be pre-fixed during assembly, and the assembly is simple and efficient. As a convertible embodiment, it is also possible that one or more first fixing structures 205 and the second fixing structures 3051 are provided respectively.

By arranging the fixing block 305 on the second cover plate 3, the fixing block 305 is provided with a second fixing structure 3051, and the circumferential edge of the first cover plate 2 is extended with the first fixing structure 205, and the extension direction of the first fixing structure 205 is perpendicular to the extension direction of the fixing block 305, the first fixing structure 205 is more tightly connected when the first fixing structure 205 is matched with the second fixing structure 3051, and it is prevented from being easily disconnected when shaking. As a convertible embodiment, it can also be that the first fixing structure 205 is a fixing hole and the second fixing structure 3051 is a boss.

[0087] like Figures 5 to 11 As shown, according to an embodiment of the present invention, on the other hand, a base assembly of a food processor is provided, comprising the above-mentioned air duct assembly.

[0088] The base assembly of the food processor includes: a shell 1, which is connected to the first cover plate 2 and the second cover plate 3 respectively, and is provided with a accommodating cavity 1013, a first through hole 10111, an air inlet 1021 and an air outlet 1022. The accommodating cavity 1013 is suitable for placing a motor, the first through hole 10111 is connected with the accommodating cavity 1013 and the first air duct 203, and the air inlet 1021 and the air outlet 1022 are both connected with the outside; the air inlet 1021 is connected with the second air duct 303, and the air outlet 1022 is connected with the accommodating cavity 1013.

[0089] By providing the shell 1 of the base assembly with a first through hole 10111 connected to the first air duct 203, when the motor in the accommodating cavity 1013 of the shell 1 runs at a high speed and generates a large amount of heat, the external incoming air can enter the second air duct 303 through the air inlet 1021, and then enter the first air duct 203 from the second air duct 303, and enter the accommodating cavity 1013 through the first through hole 10111, and then flow out from the air outlet 1022 of the shell 1 after the heat is dissipated to the motor in the accommodating cavity 1013, thereby realizing the heat dissipation of the motor.

[0090] As a convertible implementation, the air inlet 1021 may be communicated with the accommodating chamber 1013, and the air outlet 1022 may be communicated with the second air duct 303. The external air enters the accommodating chamber 1013 through the air inlet 1021, dissipates heat to the motor in the accommodating chamber 1013, and then enters the first air duct 203 through the first through hole 10111, and then enters the second air duct 303 through the first air duct 203, and then flows out from the air outlet 1022 of the housing 1 after sufficient heat dissipation, thereby achieving heat dissipation to the motor.

[0092] like Fig. 9 and Fig.10 As shown, the coupler 4 is provided with a first support structure 401, the second mounting hole 206 is provided with a second support structure 2061, the first support structure 401 and the second support structure 2061 are matched and connected, and the first support structure 401 is provided between the first mounting hole 10121 and the second support structure 2061. By providing the first support structure 401 on the coupler 4, providing the second support structure 2061 at the second mounting hole 206, and the first support structure 401 and the second support structure 2061 are matched and connected, the coupler 4 is clamped between the first cover plate 2 and the housing 1, and the coupler 4 can be pre-fixed, without the need to separately provide special screws to fix the coupler 4 as in the related art, and the assembly is simpler.

[0093] Specifically, the first support structure 401 is a boss extending outward from the coupler 4, and the second support structure 2061 is a boss extending inward from the second mounting hole 206. During assembly, the first support structure 401 of the coupler 4 can be placed on the second support structure 2061 of the first cover plate 2 to achieve pre-fixation of the coupler 4. As a convertible embodiment, the first support structure 401 can also be a buckle, and the second support structure 2061 can be a slot, and the pre-fixation assembly of the coupler 4 can be achieved by the buckle and the slot being connected.

[0094] like Fig.10 As shown, the base assembly includes a sealing device 5, which is arranged on the first support structure 401 and located between the first support structure 401 and the first mounting hole 10121. Specifically, the sealing device 5 is a sealing ring. By arranging the sealing device 5 on the first support structure 401 of the coupler 4, the coupler 4 can be sealed and waterproofed to prevent water in the cup body from leaking to the base assembly when the food processor is working, and the wire of the coupler 4 from contacting water and causing electrical safety problems.

By providing the wire-passing structures 207 on the first cover plate 2, the wires of the coupler 4 can be better fixed without the need to use cable ties and other parts to fix the wires, and the assembly efficiency is high. As a convertible embodiment, one, two, or more wire-passing structures can also be provided on the first cover plate, and no excessive restrictions are made here.

[0096] In order to facilitate assembly and wiring, a plurality of wire-passing structures 207 may be disposed on the outer edge of the first cover plate 2 .

[0097] like Figure 5 As shown, a first rib 103 is provided on one side of the shell 1 close to the first cover plate 2, and a second rib 208 is provided on one side of the first cover plate 2 close to the shell 1, and the second rib 208 is wrapped around the outside of the first rib 103. The first rib 103 extends downward along the circumference of the first through hole 10111, and the second rib 208 extends upward from the circumference of the second through hole 204. By providing the second rib 208 on the first cover plate 2, the first rib 103 is provided on the shell 1, and the second rib 208 is wrapped around the outside of the first rib 103, the sealing performance of the first cover plate 2 and the shell 1 can be ensured, so that the surroundings of the air duct cavity of the entire air duct assembly form a closed state, ensuring the functional effectiveness of the entire air duct cavity, and further preventing wind leakage.

[0098] like Figure 5As shown, the housing 1 includes: an upper shell 101, which is connected to the side of the first cover plate 2 away from the second cover plate 3; a bottom cover 102, which is connected to the upper shell 101 and is arranged on the side of the second cover plate 3 away from the first cover plate 2.

The bottom cover 102 is provided with an air inlet 1021 and an air outlet 1022, and in order to prevent the air inlet and the air outlet from affecting each other, the air inlet 1021 and the air outlet 1022 are arranged at intervals in the circumference of the bottom cover 102.

[0099] During assembly, the sealing device 5 can be firstly sleeved on the first supporting structure 401 of the coupler 4, and then the coupler 4 with the sealing device 5 can be installed from below between the first mounting holes 10121, and then the first cover plate 2 can be installed so that the second supporting structure 2061 is supported on the lower side of the first supporting structure 401, and the first supporting structure 401 is clamped between the first cover plate 2 and the bottom plate 1011 of the upper shell 101 to realize the assembly of the coupler 4.

[0100] like Figure 7 As shown, a plurality of first limiting structures 1014 are provided on the circumference of the upper shell 101, and a second limiting structure 1023 is provided on the circumference of the bottom cover 102 to be matched and connected with the first limiting structures 1014. By providing a plurality of first limiting structures 1014 on the circumference of the upper shell 101, and providing a second limiting structure 1023 on the circumference of the bottom cover 102 to be matched and connected with the first limiting structures 1014, when the upper shell 101 and the bottom cover 102 are assembled together, the upper shell 101 and the bottom cover 102 can be better limited, thereby ensuring the assembly reliability of the upper shell 101 and the bottom cover 102.

[0101] Specifically, a plurality of limiting ribs are provided on the inner wall of the upper shell 101 in the circumferential direction, and a first limiting structure 1014, i.e., a limiting groove, is provided on the limiting rib, and the second limiting structure 1023 is a limiting rib protruding outward along the upper edge of the bottom cover 102. As a convertible implementation, the first limiting structure 1014 may be a limiting rib, and the second limiting structure 1023 may be a limiting groove.

[0102] like Fig.11As shown, in order to facilitate the fixing of the upper shell 101, the first cover plate 2, the second cover plate 3 and the bottom cover 102, a first fixing through hole 1015 is provided on the upper shell 101, a second fixing through hole 209 is provided on the first cover plate 2, a third fixing through hole 306 is provided on the second cover plate 3, and a fourth fixing through hole 1024 is provided on the bottom cover 102; the base assembly includes a fixing member 6, and the fixing member 6 is penetrated through the first fixing through hole 1015, the second fixing through hole 209, the third fixing through hole 306 and the fourth fixing through hole 1024. By respectively providing the first fixing through hole 1015, the second fixing through hole 209, the third fixing through hole 306 and the fourth fixing through hole 1024 on the upper shell 101, the first cover plate 2, the second cover plate 3 and the bottom cover 102, and using a fixing member 6 to penetrate therein, the assembly and fixing effect of the upper shell 101, the first cover plate 2, the second cover plate 3 and the bottom cover 102 can be achieved, and the assembly process is simple and efficient.

[0103] Specifically, the first fixing through hole 1015 , the second fixing through hole 209 , the third fixing through hole 306 and the fourth fixing through hole 1024 are all screw holes, and the fixing member 6 is a screw.

[0104] Since many circuits need to be set on the first cover plate 2 during actual assembly, the load-bearing capacity of the first cover plate 2 will be very large. In order to ensure the load-bearing capacity of the first cover plate 2, screw columns can also be added to the bottom plate 1011 of the base upper shell 101, and screw holes can be added to the first cover plate 2, and then the two can be further fixed with screws.

[0105] The coupler 4 is also provided with two coupler fixing through holes 402, which can be used with screws to fix it together with the upper shell 101, the first cover plate 2, the second cover plate 3 and the bottom cover 102, thereby further improving the assembly efficiency.
