DETAILED DESCRIPTION

[0024] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, components, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, components, or characteristics in one or more embodiments may be combined in any suitable form.

[0025] The present invention proposes a food processor, which can be specifically manifested as different products (such as a wall-breaking machine, a blender, a food processor, etc.), providing a stirring function to break or stir food, and solving the cross-flow problem by improving the structure of a host 100 and a food processing component 200 that can be separated from the host 100, effectively improving the heat dissipation effect, so as to enhance the user experience.

[0026] Specifically, combined Figures 1 to 5As shown, the food processor comprises a main machine 100 and a food processing assembly 200 which can be separated from the main machine 100, wherein the food processing assembly 200 comprises a base 210 with a functional part 211 (such as a motor and other components) therein, a processing container 220 located on the base 210, and a food processor 221 (such as a stirring blade, etc.) disposed inside the processing container 220 and connected to the functional part 211; the main machine 100 comprises a housing and a cooling fan 120 disposed in the housing, wherein the housing is provided with an air inlet 111 and an air outlet interface 112, wherein the air inlet 111 is connected to the cooling fan 120; An air inlet channel is formed between the cooling fans 120, and an air outlet channel is formed between the cooling fans 120 and the air outlet interface 112; the base 210 is provided with an air inlet interface 212, an air outlet 213 and a heat dissipation channel 210a connected between the air inlet interface 212 and the air outlet 213, and the functional part 211 is located in the heat dissipation channel 210a; when the food processing component 200 is placed on the host 100, the air inlet interface 212 is connected to the air outlet interface 112, and the air outlet 213 and the air inlet 111 are not located on the same side.

[0027] The present invention positions the functional part 211 in the heat dissipation channel 210a. When the food processing component 200 is placed on the host 100, the air inlet interface 212 of the food processing component 200 is connected to the air outlet interface 112 of the host 100, so that the air inlet channel and the air outlet channel in the host 100 are connected to the heat dissipation channel 210a in the food processing component 200. The heat dissipation fan 120 in the host 100 is powered on, so that air is drawn into the host 100 from the air inlet 111, and the air is blown into the heat dissipation channel 210a of the food processing component 200 through the air outlet interface 112 and the air inlet interface 212, thereby performing heat exchange on the functional part 211 in the heat dissipation channel 210a, absorbing the heat emitted by the functional part 211, and discharging the heat through the exhaust port 213, thereby achieving heat dissipation treatment of the functional part 211. The present invention abandons the prior art in which the air inlet 111 and the air outlet of the heat dissipation air duct of the food processor are both arranged on the base 210, and innovatively adopts a structure in which the air outlet 213 and the air inlet 111 are not located on the same side, thereby avoiding the short distance between the air inlet 111 and the air outlet 213 and causing cross flow, effectively improving the heat dissipation effect and enhancing the user experience.

[0028] In one embodiment, the host 100 includes a control circuit board 130 disposed in the housing, and the control circuit board 130 is located in the air inlet channel. The present invention dissipates heat for the control circuit board 130 in the host 100 while dissipating heat for the functional parts 211 of the food processing assembly 200, thereby preventing the electronic components in the control circuit board 130 from failing due to excessive temperature, effectively taking away the heat of the control circuit board 130, and improving the service life.

[0029] Further, the control circuit board 130 is arranged in the air inlet channel close to the air inlet 111, or the control circuit board 130 is arranged in the air inlet channel away from the cooling fan 120. The present invention arranges the control circuit board 130 close to the air inlet 111 so that the cold air entering the air inlet channel through the air inlet 111 can contact the control circuit board 130 in a large area and take away the heat of the control circuit board 130; or the control circuit board 130 is arranged in the air inlet channel away from the cooling fan 120 to avoid the situation where the control circuit board 130 can only contact with a small area of ​​cold air due to being arranged close to the cooling fan 120.

[0030] Furthermore, the air inlets 111 are distributed along the installation direction of the control circuit board 130 , so that the control circuit board 130 can be fully in contact with the cold air entering through the air inlets 111 , thereby improving the heat dissipation effect.

[0031] In one embodiment, the cooling fan 120 is arranged close to the air outlet interface 112, so that the air volume of the air outlet interface 112 is guaranteed, so as to avoid affecting the heat dissipation of the functional parts 211 in the heat dissipation channel 210a due to insufficient air volume, and the noise generated by the cooling fan 120 will pass through the air outlet interface 112 to the exhaust port 213 of the food processing component 200, and the noise reduction effect is achieved by increasing the propagation distance of the noise. Among them, the air outlet channel formed between the cooling fan 120 and the air outlet interface 112 is an air guide duct, one end of which is connected to the air outlet interface 112, and the other end is connected to the air outlet position of the cooling fan 120, so that the wind generated by the cooling fan can be completely transmitted to the air outlet interface 112 through the air guide duct, and sent into the heat dissipation channel in the food processing component through the air outlet interface 112.

[0032] In one embodiment, the position of the cooling fan 120 is higher than the position of the air outlet 112. The present invention raises the position of the cooling fan 120 and makes it higher than the position of the air outlet 112. Even if the host 100 of the present invention encounters an unexpected situation, such as when the user accidentally knocks over a cup on the table and causes water to submerge the bottom of the host 100, the water will not easily enter the host 100 and contact the cooling fan 120, which improves the waterproofness of the cooling fan of the present invention to a certain extent, avoids safety accidents caused by the cooling fan working after contacting water, and increases the safety of the present invention.

[0033] Furthermore, the air inlet 111 and the air outlet 112 are respectively located on different sides of the housing, thereby avoiding cross-flow between the air inlet 111 and the air outlet 112 due to the short distance, and / or the air inlet 212 and the air outlet 213 are not located on the same side of the food processing component 200, thereby avoiding cross-flow between the air inlet 212 and the air outlet 213 due to the short distance. The present invention achieves that the air outlet 213 and the air inlet 111 are not located on the same side in the above manner, thereby solving the cross-flow problem caused by the short distance between the air outlet 213 and the air inlet 111 during the heat dissipation process.

[0034] In one embodiment, the shell includes an outer wall 113 and an inner wall 114; a portion of the outer wall 113 and the inner wall 114 together form a storage chamber 115 for accommodating a control circuit board 130 and a cooling fan 120; another portion of the outer wall 113 and the inner wall 114 together form a receiving chamber 116 for accommodating the food processing component 200, and at least one side of the receiving chamber 116 is provided with an opening for providing the food processing component 200 to be placed or separated relative to the shell; the air inlet 111 is arranged on the outer wall 113 of the shell, and the air outlet interface 112 is located in the receiving chamber 116. The present invention prevents cross-flow by arranging the air inlet 111 and the air outlet interface 112 on different sides of the shell respectively, and the cooling fan 120 is arranged in the receiving chamber 115, and the cooling fan 120 is surrounded by the outer wall 113 and the inner wall 114, which can effectively reduce the noise generated by the cooling fan 120.

[0035] Furthermore, the base 210 is provided with a first electric coupler 214, and the inner wall 114 is provided with a second electric coupler 117 corresponding to the first electric coupler 214. When the food processing component 200 is placed in the accommodating cavity 116 on the main unit 100 through the opening, the first electric coupler 214 is electrically connected to the second electric coupler 117, so that the main unit 100 can supply power to the food processing component 200 and transmit control signals.

[0036] Furthermore, the shell includes a supporting portion arranged in the accommodating cavity. When the food processing component 200 is placed on the main unit 100, the upper end surface of the supporting portion abuts against the lower end surface of the base to support the food processing component 200 while facilitating the docking of the air inlet interface with the air outlet interface, as well as the docking of the first electrical coupler with the second electrical coupler.

[0037] In one embodiment, the exhaust port 213 is arranged on the base 210 so as to face away from the air inlet interface 212; the exhaust port 213 exposes the opening when the food processing component 200 is placed on the main unit 100; the present invention arranges the exhaust port 213 to face away from the air inlet interface 212 (i.e., the air inlet interface 212 and the exhaust port 213 are 180° apart) so that the airflow entering from the air inlet interface 212 has a sufficient movement path, ensuring full contact with the functional part 211, taking away the heat of the functional part 211, facilitating smooth discharge of hot air and improving heat dissipation efficiency, and such an arrangement can also increase the distance between the exhaust port 213 and the air inlet interface 212 to prevent cross-flow.

[0038] In one embodiment, the heat dissipation channel 210a includes a accommodating channel 217, a heat dissipation air inlet channel 215 connected to the air inlet interface 212, and a heat dissipation air outlet channel 216 connected to the exhaust port 213; the functional part 211 is located in the accommodating channel 217; the heat dissipation air inlet channel 215 is connected to the accommodating channel 217 through the heat dissipation air inlet, and the heat dissipation air outlet channel 216 is connected to the accommodating channel 217 through the heat dissipation air outlet. The horizontal height of the heat dissipation air inlet is lower than the horizontal height of the heat dissipation air outlet to ensure that the airflow blows obliquely upward from the heat dissipation air inlet through the functional parts and then goes out from the heat dissipation air outlet, thereby better taking away the hot air.

[0039] In an actual use scenario, when a food processor is used as a household appliance with a wall breaking function or a stirring function, the food processing component is placed in the accommodating cavity of the main unit through the opening, and the first electrical coupler and the second electrical coupler are electrically connected; the functional part (motor) is powered on to drive the food processor (stirring knife) inside the processing container to rotate, and stir or break the food; at the same time, the cooling fan in the main unit is powered on, and the air outside the main unit enters the storage cavity through the air inlet and forms a wind flow under the action of the cooling fan. The wind flow blows through the control circuit board and takes away the heat generated by the control circuit board, thereby cooling the control circuit board; after cooling the control circuit board, the wind flow enters the heat dissipation channel in the base through the air outlet interface and the air inlet interface under the action of the cooling fan, cools the functional parts located in the heat dissipation channel, and is finally discharged through the exhaust port to achieve heat dissipation and cooling of the control circuit board and the functional parts.

[0040] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
