[0028] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, 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, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0029] Combination Figures 1 to 7As shown, the present invention relates to a self-cleaning food processor (referred to as "food processor") with reliable structure, including a machine base 1 provided with a motor 21, a processing container 22 provided on the machine base 1, a processing device 23 provided in the processing container 22 and driven by the motor 21, and a container cover 4 connected to the processing container 22, wherein the container cover 4 is rotatably connected to the upper end of the machine base 1 through a rotating shaft 49; and also includes a spray device 5 provided on the inner side wall of the container cover 4 and a water supply system connected to the spray device 5, wherein the water supply system supplies water to the spray device 5 so that the spray device 5 provides spray cleaning for the food processor without user intervention.

[0030] Among them, the water supply system includes: a water tank 30 arranged on the machine base 1; an adapter 35, including a first water supply connector 351 and a second water supply connector 352 that are connected to each other, and the central axis O-O' of the first water supply connector 351 is basically coaxial with the central axis of the rotating shaft 49; a first water supply pipe 33 connected between the first water supply connector 351 and the water tank 30 through a water pump 31; a second water supply pipe 34 connected between the spray device 5 and the second water supply connector 352, and the second water supply pipe 34 is arranged on the container cover 4.

[0031] Among them, a rotating portion is provided on one side of the container cover 4, and a rotating hole 48 is provided on the rotating portion; a rotating seat 10 is correspondingly provided at the upper end of the machine base 1, and the end of the rotating shaft 49 passes through the rotating hole 48 and is pivotally connected to the rotating seat 10, so that the container cover 4 can be opened or closed relative to the processing container 22 according to the rotating shaft 49. This is understandable to technicians in the relevant field.

[0032] Since the first water supply connector 351 is substantially coaxial with the rotating shaft 49, this structure allows the first water supply connector 351 to rotate in the same direction as the rotating shaft 49 during the rotation of the container cover 4 to open or close the processing container 22 according to the rotating shaft 49. The adapter 35 substantially provides a buffer for the first water supply pipe 33, thereby reducing the pulling amplitude on the first water supply pipe 33 during the rotation process, thereby ensuring that both ends of the first water supply pipe 33 maintain a stable and reliable connection with the first water supply connector 351 and the water pump 31, respectively.

[0033] Preferably, the central axis PP' of the second water supply connector 352 substantially intersects with the central axis of the rotating shaft 49. This structure can further reduce the pulling amplitude of the second water supply pipe 34 caused by the rotation of the container cover 4 using the rotating shaft 49, especially from Figure 7 The container cover 4 is switched to the open state as shown. Figure 6 In the covered state shown, the pulling amplitude on the second water supply pipe 34 is reduced, thereby facilitating preventing the two ends of the first water supply pipe 34 from being loosened relative to the spray device 5 and the second water supply connector 352 during the frequent rotation operation of the container cover 4.

[0034] The present invention optimizes the structure of the water supply system, adopts a first water supply pipe 33 and a second water supply pipe 34 of segmented design, and the two are connected by an adapter 35. By cleverly designing the angular relationship between the first water supply joint 351 and the second water supply joint 352 of the adapter 35 relative to the rotating shaft 49, when the container cover 4 is rotated relative to the processing container 22 to open or close, the adapter 35 provides a buffer to reduce the pulling on the first water supply pipe 33 and the second water supply pipe 34, ensuring that the first water supply pipe 33 and the second water supply pipe 34 will not get loose during the frequent rotation operation of the container cover 4, thereby improving the structural reliability of the water supply system, which is beneficial to improving the working reliability and service life of the food processing machine, and also provides a prerequisite for providing reliable self-cleaning spray cleaning for the food processing machine.

[0035] Furthermore, the food processor disclosed in the present invention adopts a water supply system to pump water from a water tank to the container cover and provide it to the spray device 5, and the spray device 5 is used to spray toward the upper end of the inner wall of the processing container 22 and / or the inner wall of the container cover 4, thereby providing a thorough cleaning of the food processor without the need for user participation in the cleaning, and the cleaning effect is good.

[0036] The upper end of the first water supply pipe 33 is connected to the first water supply connector 351, and the lower end of the first water supply pipe 33 is connected to the water pump 31. The upper end of the first water supply pipe 33 has a connecting section 331 formed by bending, and the extension direction of the connecting section 331 is substantially consistent with the central axis O-O' of the first water supply connector 351, and the connecting section 331 is connected to the end of the first water supply connector 351 by sleeve connection. This structure makes the connection between the first water supply pipe 33 and the first water supply connector 351 less likely to loosen and more reliable, and is also conducive to using the bending of the connecting section 331 to provide buffering for the pulling of the first water supply pipe 33 when the container cover 4 rotates.

[0037] There is a first bend 332 between the upper and lower ends of the first water supply pipe 33, and a second bend between the two ends of the second water supply pipe 34. This structure has better pulling resistance than a straight pipe, which is conducive to improving the reliability of the water supply system.

[0038] The water tank 30 has a water outlet joint 301, and the water pump 31 is connected to the water outlet joint 301 through the water outlet pipe 32 to extract water from the water tank 30. Specifically, the water outlet joint 301 is arranged at the bottom of the water tank 30, the water inlet end of the water pump 31 is connected to the water outlet joint 301 through the water outlet pipe 32, and the water outlet end of the water pump 31 is connected to the lower end of the first water supply pipe 33. The first water supply pipe 33 is hidden between the water tank 30 and the outer side surface of the machine base 1, so that the first water supply pipe 33 does not affect the overall appearance of the food processor.

[0039] Especially combined with Figures 4 to 7As shown. The container cover 4 includes an outer cover and an inner cover 42 connected to the outer cover. A third water supply connector 38 is provided on the inner cover 42, and the lower end of the third water supply connector 38 is exposed outside the inner cover 42, and the spray device 5 is connected to the lower end of the third water supply connector 38; the two ends of the second water supply pipe 34 are respectively connected between the upper end of the third water supply connector 38 and the upper end of the second water supply connector 352. The spray device 5 and the lower end of the third water supply connector 38 can be detachably assembled so that the spray device 5 is installed on the inner side wall of the container cover 4.

[0040] Preferably, the second water supply pipe 34 is hidden between the outer cover 41 and the inner cover 42 so that the second water supply pipe 34 does not affect the overall appearance of the food processor, while also protecting the second water supply pipe 34 from being damaged by external factors during use.

[0041] Especially see Figure 4 In the preferred embodiment shown, a receiving groove 420 is provided on the side edge of the inner cover 42 of the container cover 4, and the adapter 35 is located in the receiving groove 420, and the adapter 35 is limited in the receiving groove when the outer cover and the inner cover 42 are covered. This structure makes the adapter 35 easy to install and will not fall off, and enables the central axis OO' of the first water supply connector 351 of the adapter 35 to be substantially coaxial with the rotating shaft 49.

[0042] See further Figure 8 In the embodiment shown, a one-way valve 37 is installed on the first water supply pipe 33. Of course, the one-way valve 37 can also be installed on the second water supply pipe 33. Figure 8 The one-way valve 37 shown is installed in the first water supply pipe 33 as an example: when the water pump 31 is started, the pumped water passes through the one-way valve 37 to flush the one-way valve 37 and switch it to the open state, so that the water in the first water supply pipe 33 can be smoothly sent to the spray device 5 through the one-way valve 37; on the contrary, when the water pump 31 stops, the water in the first water supply pipe 33 loses the pumping pressure, and the water cannot flush the one-way valve 37, so that the one-way valve 37 switches to the closed state, and the one-way valve 37 is used to prevent the circulation of air, so that the water remaining between the one-way valve 37 and the second water supply pipe 34 will not flow out. In this way, the problem that when the user removes the container cover 4, the water remaining in the water supply system will not flow out from the spray device 5 to the user's desktop or kitchen stove is solved, which is conducive to further improving the user's use experience.

[0043] Further integration Fig. 9 and Fig.10As shown, the spray device 5 includes a spray body 51 with a water channel, a water inlet joint 53 provided on the spray body 51 and connected to the second water supply pipe 34, a first nozzle 56 for spraying a water column toward the upper end of the inner wall of the processing container 22, and a second nozzle 55 for spraying a water column toward the inner side wall of the container cover 4. The first nozzle 56 and the second nozzle 55 are both provided on the spray body 51 and are both connected to the water channel. The spray device 5 is directly connected to the lower end of the third water supply joint 38 on the inner cover 42 by the water inlet joint 53. After the water in the water tank 30 is pumped to the water channel of the spray device 5 by the water supply system, it is sprayed from the nozzle 55 toward the upper end of the inner wall of the processing container 22 or / and the inner side wall of the container cover 4, thereby providing a thorough cleaning of the food processor with a good cleaning effect.

[0044] The spray body 51 is located on both sides of the central axis of the water inlet joint 53, and any one of the side wings overlaps with the other side wing after rotating 180° around the central axis of the water inlet joint 53. This structure enables a pair of first nozzles 56 of the spray device 5 to generate a driving force couple that drives the spray body 51 to rotate around the central axis of the water inlet joint 53, allowing the spray device 5 to provide a more effective spray cleaning during rotation. Furthermore, the water channel is gradually reduced from the connection with the water inlet joint 53 toward the first and second nozzles, so that the water pressure of the water entering the water channel increases continuously as it flows through the water channel, which is conducive to increasing the strength of the spray water column to improve the spray cleaning effect, and can also generate a larger driving force couple.

[0045] A fixing sleeve 421 surrounds the lower end of the third water supply connector 38 on the inner side wall of the container cover 4 (i.e., the lower side of the inner cover 42), and a limiting ring 422 is provided on the outer side of the fixing sleeve 421; a pair of buckles 54 are provided on the spray body 51, the water inlet connector 53 is sleeved with the lower end of the third water supply connector 38 on the inner cover 42, and the buckle 54 is buckled on the limiting ring 422, so that the spray device 5 can be detachably assembled on the inner side wall of the container cover 4.

[0046] The processor 23 is generally a blender or a crushing blade. When the processor 23 is a blender, it provides a function of blending, stirring and mixing the food in the processing container 22 under the drive of the motor 21. When the processor 23 is a crushing blade, it provides a function of chopping and smashing the food in the processing container 22 under the drive of the motor 21.

[0047] The work of the food processing machine includes a food processing stage and a machine cleaning stage. In the food processing stage, the motor 21 drives the processing processor 23 to process the food in the processing container 22 accordingly. After the food processing stage is completed, after the food is taken out of the processing container 22, the food processing machine can enter the machine cleaning stage as needed. The machine cleaning stage includes a spray cleaning stage and a rotation cleaning stage.

[0048] During the spray cleaning stage, the water pump 31 pumps water from the water tank 30 to the first water supply pipe 33, and the water is pumped to the spray device 5 with a certain water pressure through the first water supply pipe 33 and the second water supply pipe 34. The water channel entering the spray device 5 has a certain pressure. The pressurized water flows in the water channel to the first nozzle 56 and the second nozzle 55 and is sprayed toward the upper end of the inner wall of the processing container 22 and / or various positions of the inner wall of the container cover 4, so as to rinse off the food remaining on the upper end of the inner wall of the processing container 22 and the inner wall of the container cover 4.

[0049] After the spray cleaning stage is completed, the water pump 31 is turned off and the motor 21 is started again to drive the processing unit 23 to rotate rapidly in the processing container 22, so that the processing unit 23 drives the water flow in the processing container 22 to rotate and roll to form a vortex, which will flush and clean the food remaining in the processing unit 23, the lower end of the inner wall of the processing container 22 and the bottom.

[0050] After the machine cleaning stage, the interior of the processing container 22, the inner wall of the container cover 4 and the processing processor 23 can be completely and thoroughly cleaned, which is beneficial to improve the cleaning effect and enhance the user experience. It also effectively prevents bacteria from growing in cleaning dead corners due to the long-term presence of food residues to ensure hygienic and safe use.

[0051] 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.
