[0042] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0043] Reference Figures 1 to 9 As shown, a pot washing pretreatment module of an embodiment of the utility model is used for washing a pot body 100, comprising: a frame 200, a water pool 300, a movable frame 400, a baffle 600, and a cleaning device 700. The water pool 300 is connected to the frame 200; the frame 200 is composed of thin steel plates and steel sections. In order to prevent the frame 200 and the water pool 300 from rusting and corroding, the material of the frame 200 and the water pool 300 is stainless steel. The water pool 300 is used to store water with detergent. The pot body 100 is soaked in the water pool 300 before washing to soften the residue in the pot body 100 for subsequent cleaning. The movable frame 400 is arranged at the front end of the frame 200 in a manner that can be moved forward and backward and adjusted. The frame 200 is connected to a first guide rail extending forward and backward. A roller is rotatably installed at the lower end of the movable frame 400, and the roller moves along the first guide rail to reduce the friction of the movable frame 400 moving forward and backward. A positioning device 500 is provided at the front end of the movable frame 400. The positioning device 500 defines an installation position for vertically positioning the pot body 100. After the staff places the pot body 100 on the installation position, the positioning device 500 plays a role in preliminary positioning of the pot body 100. The movable frame 400 has a working state and an exit state during the process of moving forward and backward adjustment. In the working state, the installation position is located in the upper area of ​​the pool 300, and the oil stains of the pot body 100 located at the installation position will directly fall into the pool 300 after being cleaned. In the exit state, the movable frame 400 at least partially exits the upper area of ​​the pool 300, which is convenient for the staff to clean the inside of the pool 300. The baffle 600 is arranged at the front end of the movable frame 400 so as to be movable and adjustable up and down. The height of the baffle 600 when it is in the first state is greater than the height of the baffle 600 when it is in the second state. The baffle 600 has a first state and a second state during the up and down adjustment process. In the first state, the baffle 600 is located at the front end of the installation position, and the baffle 600 abuts against the front end of the pot body 100 located at the installation position to prevent the pot body 100 from detaching from the installation position. In the second state, the baffle 600 withdraws upward from the installation position. At this time, the staff can remove the pot body 100 from the installation position and transport it to the next cleaning process. The cleaning device 700 is arranged at the front end of the movable frame 400. When the baffle 600 is in the second state, the cleaning device 700 cleans the inside of the pot body 100, removes the oil and residue in the pot body 100, and the cleaned oil flows into the pool 300 under the action of gravity.

[0044] Reference Figure 3As shown, it is understandable that the pot washing pretreatment module also includes a locking assembly 800, which is arranged between the frame 200 and the movable frame 400, and is used to lock the movable frame 400 when the movable frame 400 is in the working state or in the exit state. Since vibration is generated when washing the pot body 100, it is necessary to fix the movable frame 400 in the working state. It is foreseeable that the locking assembly 800 can only fix the movable frame 400 in the working state, and in the exit state, the movable frame 400 does not need to be fixed, and the movable frame 400 is moved to facilitate cleaning the gap between the movable frame 400 and the frame 200.

[0045] Reference Figure 2 and Fig. 9 As shown, it can be understood that the locking assembly 800 includes a clamping portion 810 and a positioning column 820, the positioning column 820 is vertically welded on the frame 200, and the frame 200 is provided with at least two positioning columns 820 along the front-to-back direction, the clamping portion 810 is rotatably connected to the movable frame 400, and a handle is also connected to the clamping portion 810 to facilitate the control of the rotation of the clamping portion 810. The clamping portion 810 is welded with two front-to-back distributed card plates 811, and the spacing between the two card plates 811 is adapted to the size of the positioning column 820 along the front-to-back direction so that the positioning column 820 can just be embedded between the two card plates 811, and the locking assembly 800 is configured as follows: when the clamping portion 810 is aligned with the positioning column 820 along the left-right direction, it can be rotated under the action of external force until the two card plates 811 are respectively located at the front and rear sides of the positioning column 820. When the movable frame 400 is in the working state, the clamping portion 810 is aligned with the positioning column 820 located in the front of the two positioning columns 820 in the left-right direction. When the movable frame 400 is in the withdrawn state, the clamping portion 810 is aligned with the rear positioning column 820 of the two positioning columns 820 in the left-right direction.

[0046] Reference Figure 4 and Figure 8As shown, it can be understood that the positioning device 500 includes a first positioning portion 510 and a second positioning portion 520, and the first positioning portion 510 is provided with a fitting groove with an opening at the lower end, and the fitting groove extends in the left-right direction. The fitting groove is for the edge of the pot body 100 to be embedded, and the size of the fitting groove matches the thickness of the pot body 100 to limit the pot body 100. The second positioning portion 520 is located directly below the first positioning portion 510, and the upper end of the second positioning portion 520 is provided with a horizontally arranged support surface, and the distance between the first positioning portion 510 and the second positioning portion 520 in the vertical direction is adapted to the length or width of the pot body 100. When installing the pot body 100, the staff first inserts the edge of the pot body 100 into the fitting groove from bottom to top, and then rotates the pot body 100 with the fitting groove as a fulcrum until the edge of the pot body 100 is against the support surface, and the support surface provides an upward support force for the pot body 100. At this time, the fitting groove plays a role in limiting the front and rear positions of the edge of the pot body 100. After the pot body 100 is initially fixed by the positioning device 500, it will not move when there is no external force or the external force is small. However, when the cleaning device 700 cleans the pot body 100, the pot body 100 is pushed forward by the cleaning device 700, so the baffle 600 needs to be moved down to the first state to block the front end of the pot body 100 to prevent the pot body 100 from moving when being cleaned.

[0047] Reference Figure 3 As shown, it can be understood that the pot washing pretreatment module includes a locking device 900, which is installed between the movable frame 400 and the baffle 600. The locking device 900 is used to lock the baffle 600 when the baffle 600 is in the second state. After the pot body 100 is cleaned by the cleaning device 700, the pot body 100 needs to be taken out. When taking out the pot body 100, the baffle 600 needs to be moved upward to the second state first, and then the pot body 100 is taken out. Since taking out and putting in the pot body 100 usually requires both hands to operate, the baffle 600 needs to be fixed by the locking device 900 to facilitate the operation of a single staff member.

[0048] Reference Figure 3 and Figure 7As shown, it can be understood that the locking device 900 includes a slider 910, a reset member 920, and a positioning pin 930. A guide box is provided at the upper end of the movable frame 400. The slider 910 is connected to the mounting block. The mounting block is installed in the guide box. The mounting block can be moved and adjusted in the horizontal direction in the guide box. A clearance groove for the positioning pin 930 to pass through is vertically opened on one side of the guide box close to the baffle. A plurality of wheels are rotatably installed at the upper and lower ends of the mounting block to reduce the friction of the mounting block moving in the guide box. The reset member 920 is provided between the mounting block and the movable frame 400, and the reset member 920 is selected from a spring. The reset member 920 is used to keep the mounting block in the middle position under normal conditions. The mounting block in the middle position can overcome the elastic force of the reset member 920 and move in the forward and backward directions. A slider 910 is provided on the side of the mounting block close to the baffle 600. A positioning groove 911 is provided on the slider 910. One end of the positioning groove 911 is open. The opening of the positioning groove 911 is inclined forward and upward, and the other end thereof is inclined downward. The slider 910 is provided with a first guide surface 912 below the positioning groove 911, and a second guide surface 913 above the positioning groove 911. The inclination direction of the first guide surface 912 and the second guide surface 913 is the same as that of the positioning groove 911. A positioning pin 930 is connected to the baffle 600. The outer diameter of the positioning pin 930 is adapted to the width of the positioning groove 911, and the horizontal projection of the slider 910 in the middle position covers the horizontal projection of the positioning pin 930. When the positioning pin 930 rises with the baffle 600, it first contacts the first guide surface 912, pushing the slider 910 and the mounting block to move backward. When the positioning pin 930 rises to the opening of the positioning groove 911, the reset member 920 pushes the mounting block back to the middle position. The positioning pin 930 enters the positioning groove 911, and the positioning groove 911 plays a supporting role to prevent the positioning pin 930 from moving downward. At this time, the baffle 600 is fixed in the second state. When it needs to be contacted and fixed, the baffle 600 is further moved upward, and the positioning pin 930 contacts the second guide surface 913 to push the slider 910 and the mounting block backward until the positioning pin 930 leaves the second guide surface 913, and then the reset member 920 pushes the mounting block forward to the middle position, and then the baffle 600 is moved downward, and the positioning pin 930 moves downward to contact the second guide surface 913, pushing the slider 910 and the mounting block forward until the positioning pin 930 leaves the second guide surface 913, and then the baffle 600 can continue to move downward to the first state.

[0049] Reference Figure 7 As shown, it can be understood that the rear end of the baffle 600 is connected to a clamping frame 610. The clamping frame 610 is bolted to the rear end of the baffle 600, and the clamping frame 610 is used to abut against the front end of the pot body 100 to fix the pot body 100.

[0050] Reference Figures 1 to 9As shown, it can be understood that the cleaning device 700 includes a first driving member 710 and a bracket 720. The bracket 720 is arranged on the movable frame 400 so as to be movable forward and backward. The bracket 720 is connected to the movable frame 400 through a slide rail and a pulley. The connection method between the bracket 720 and the movable frame 400 is a prior art, so it will not be described in detail. A brush 730 is arranged at the front end of the bracket 720, and the first driving member 710 is used to drive the bracket 720 to move forward and backward. The brush 730 is used to clean the burnt scale in the pot body 100, and the cleaning effect is good.

[0051] Reference Figures 1 to 9 As shown, it can be understood that there are multiple brushes 730. It can be foreseen that when the pot body 100 is a four-grid hot pot or a double-flavored hot pot, the pot body 100 is divided into multiple areas, and a brush 730 is set for each area for cleaning. The brush 730 is fixedly mounted on the bracket 720. The shape of each brush 730 is the same as the shape of the pot body 100.

[0052] Reference Figures 1 to 9 As shown, it can be understood that the first driving member 710 includes a first motor 711, a rotating wheel 712 and a transmission plate 713, an eccentric rod 714 is eccentrically mounted on the rotating wheel 712, the rotating wheel 712 is mounted on the output shaft of the first motor 711, the transmission plate 713 is bolted to the bracket 720, a vertically extending waist-shaped hole 715 is opened on the transmission plate 713, the eccentric rod 714 extends into the waist-shaped hole 715, and the eccentric rod 714 is configured as follows: when the eccentric rod 714 rotates with the rotating wheel 712, the eccentric rod 714 can move up and down along the waist-shaped hole 715, thereby driving the waist-shaped hole 715 to move forward and backward. The first motor 711 is a servo motor to control the movement of the eccentric rod 714, so that the first motor 711 can control the bracket 720 to move forward and backward. The brush 730 can be inserted into the pot body 100 to clean the pot body 100.

[0053] It is foreseeable that in some other embodiments of the utility model, a nozzle for spraying water containing detergent to the brush 730 is installed on the bracket 720, and the nozzle is connected to a water pump, and the water pump is used to pump out the water containing detergent in the pool 300. During the cleaning process of the brush 730, the detergent will flush away the oil and dirt cleaned, thereby improving the cleaning effect.

[0054] It is foreseeable that in some other embodiments of the present invention, a bubbling tube is provided at the bottom of the water pool 300. By inputting compressed air into the bubbling tube, bubbles can be generated in the water pool 300 to improve the effect of cleaning the pot body 100. A heater is provided on the side wall of the water pool 300. The heater is used to heat the water with detergent in the water pool 300 to achieve a better effect of removing solidified oil stains.

[0055] Usage steps: move the movable frame 400 to the working state, lock the movable frame 400 with the locking device, insert the edge of the pot body 100 into the fitting groove from bottom to top, then use the fitting groove as a fulcrum to rotate the pot body 100 until the edge of the pot body 100 abuts against the support surface, move the baffle 600 in the second state upward, so that the locking device 900 cancels the fixation of the baffle 600, and then move the baffle 600 downward to the first state, the baffle 600 abuts against the front end of the pot body 100, start the first motor 711, and the eccentric rod 714 drives the transmission plate 713 to move in the front and rear direction, so that the brush 730 repeatedly enters and exits the pot body 100. After cleaning is completed, move the baffle 600 upward until the baffle 600 is fixed in the second state by the locking device 900. Then take out the pot body 100 to complete the pre-cleaning of the pot body 100.

[0056] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
