Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic cleaning, in particular to a cleaning and brightening device using ultrasonic waves through two frequencies. Background Art

[0002] Ultrasonic waves have excellent cleaning ability in cleaning tableware. When the ultrasonic cleaning device is working, the transducer converts electrical energy into high-frequency mechanical vibration, and then transmits the ultrasonic energy to the surrounding through the cleaning liquid in the cleaning tank. In the cleaning liquid, ultrasonic waves generate tens of thousands of tiny bubbles, which are quickly closed and generate instantaneous high pressure under the action of sound waves. This high-pressure impact can strongly impact the surface of tableware and quickly remove stains and oil stains attached to the tableware. Compared with traditional manual cleaning or mechanical cleaning, ultrasonic cleaning can remove stains and oil stains more thoroughly;

[0003] At present, when using ultrasound to clean tableware, the tableware is basically directly placed in the ultrasonic cleaning tank, and then the cleaned tableware is taken out from the cleaning tank. The above cleaning method has a low degree of automation. When facing a large number of canteen tableware, it is not conducive to realizing automatic loading and cleaning and automatic unloading and drying of a large number of tableware, thereby affecting the cleaning efficiency of the tableware;

[0004] Studies have found that low-frequency ultrasound has strong penetrating power and can penetrate deep into the tiny gaps and dead corners on the surface of tableware to effectively remove stubborn stains. High-frequency ultrasound has higher cleaning accuracy and stronger cleaning power, and can clean the surface of tableware more carefully and remove tiny stains and particles. Currently, most ultrasonic cleaning methods usually use single-frequency sound waves to work, resulting in poor cleaning effects. Utility Model Content

[0008] Further: Two baffle plates one and three baffle plates two are hinged between the tops of the two side plates, and a baffle plate three is detachably fixed between the bottoms of the two side plates.

[0009] Further: A motor for driving the lead screw to rotate is embedded and fixed at the top of one side plate, and a drying box is embedded and fixed at the top of the other side plate, and the drying box is fixedly connected to the air outlet end of an external dryer.

[0010] Further: Rectangular water pipes are fixedly installed at the tops of the slag filtering tank and the rinsing tank, a plurality of spray pipes are fixedly connected at equal intervals on the outside of the rectangular water pipe, a water spray nozzle is fixedly installed inside the spray pipe, and the rectangular water pipe is fixedly connected to the water outlet end of an external water pump through a pipeline.

[0012] Further: A water receiving hopper is fixed at the top of the support frame, two support rods are fixed inside the water receiving hopper, and the support rods are in contact with the bottom of the outer frame.

[0013] Further: Two peripheral rods are sleeved and fixed on the outside of the outer frame, and arc-shaped rods are embedded and fixed at both ends of the C-shaped rod.

[0014] Further: The traction mechanism includes a moving seat screwed to the lead screw, the moving seat is slidably connected to the guide rail, electric push rods are fixed at both ends of the bottom surface of the moving seat, a connecting rod is fixed at the output end of the electric push rod, and hooks are fixed at both ends of the connecting rod.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. By placing the tableware tray to be cleaned into the cleaning frame, then placing the cleaning frame on the trolley, and using the trolley to convey multiple tablewares inside the cleaning frame to one end of the cleaning machine case. The lead screw rotates to drive the traction mechanism to move above the cleaning frame and hang the U-shaped plate on the cleaning frame. Then the lead screw rotates in the reverse direction to make the traction mechanism transfer the cleaning frame and the tableware tray above the slag filtering tank. The output end of the electric push rod on the traction mechanism extends, so that the cleaning frame drives the tableware tray to soak and spray inside the slag filtering tank, which is convenient for washing the slag on the tableware;

[0017] The lead screw rotates to make the traction mechanism transfer the tableware tray inside the cleaning frame above the ultrasonic cleaning tank. The output end of the electric push rod on the traction mechanism extends, so that the cleaning frame drives the tableware tray to move into the ultrasonic cleaning tank. The ultrasonic generator generates ultrasonic waves, and the ultrasonic waves are conducted into the cleaning water through the vibrator. The vibrating ultrasonic waves generate many tiny bubbles per second in the water. When the bubbles collide with the tableware, shock waves are generated when the bubbles burst on the surface of the tableware. The impact force generated by countless bubble shock waves makes the dirt break away from the tableware, realizing full cleaning of the tableware tray;

[0018] The lead screw rotates to make the traction mechanism transfer the tableware tray inside the cleaning frame above the flushing tank. The output end of the electric push rod on the traction mechanism extends, so that the cleaning frame drives the tableware tray to move into the flushing tank. Multiple spray pipes further spray and wash the tableware tray to improve the cleanliness and brightness of the tableware tray;

[0019] Finally, the lead screw rotates to drive the traction mechanism to transfer the tableware tray on the cleaning frame to the outside of the drying box, which is convenient for drying the cleaned tableware tray, and makes the cleaning frame fall on the trolley, which is convenient for the user to take out the cleaned tableware tray, thus realizing the combination of automatic feeding, multi-process cleaning and automatic discharging and drying of the tableware, which is beneficial to improving the cleaning efficiency of the tableware.

[0020] 2. By installing and fixing a low-frequency ultrasonic generator and a high-frequency ultrasonic generator on the inner bottom of the ultrasonic cleaning tank, the tableware tray in the cleaning tank is cleaned by ultrasonic waves of two frequencies at the same time. The ultrasonic waves of two different frequencies can generate cavitation bubbles of different sizes. One frequency may generate larger bubbles, while the other frequency generates smaller bubbles. Bubbles of different sizes can more comprehensively cover and clean the surface of the object, improving the cleaning efficiency;

[0021] Using two frequencies may help reduce redeposition of dirt during the cleaning process. One frequency may be responsible for loosening dirt, while the other frequency helps prevent dirt from reattaching to the surface of the object. The two frequencies of ultrasound can be used at different stages to optimize the cleaning process. For example, one frequency is used in the initial stage to loosen dirt, and then another frequency is used in the final stage to completely remove dirt and improve the brightness of the cutlery plates.

[0022] 3. By placing a small number of cutlery plates that need to be cleaned at one end of the cleaning frame, extending the output end of an electric push rod and shortening the output end of the other electric push rod, the two sets of hooks can be used to tilt the cleaning frame above the filter residue tank, ultrasonic cleaning tank or rinse tank (the various types of tanks are collectively referred to as clean tanks below), so that the cleaning frame can be tilted with the cutlery plates into the clean tank for cleaning. Compared with the traditional vertical cleaning of the cutlery plates, the tilted cleaning achieves the cleaning effect with a small amount of cleaning liquid, which is convenient for effectively saving water when cleaning a small number of cutlery plates.

Detailed implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] Example 1, please refer to Figures 1 to 8 , in the embodiment of the present invention, an ultrasonic two-frequency cleaning and brightening device includes a cleaning chassis 100. The cleaning chassis 100 includes two symmetrically arranged side plates 110. A top plate 120 is fixed between the tops of the two side plates 110. A filter residue tank 200, an ultrasonic cleaning tank 300, and a flushing tank 400 are arranged between the two side plates 110. Two ultrasonic generators 310 are fixedly installed at the inner bottom of the ultrasonic cleaning tank 300. A plurality of vibrators 320 are fixedly installed on both sides of the ultrasonic cleaning tank 300. Trolleys 500 are placed at both ends of the cleaning chassis 100. The trolley 500 includes a support frame. A cleaning frame 600 is detachably placed on the top of the support frame. The cleaning frame 600 includes an outer frame 610. A plurality of cross bars 620 are equidistantly fixed at the bottom of the outer frame 610. A plurality of U-shaped limiting rods 621 for clamping and placing tableware are equidistantly fixed at the top of the cross bar 620. Two C-shaped rods 630 are fixed at the top of the outer frame 610. A guide rail 700 fixedly connected to the side plate 110 is arranged at the bottom of the top plate 120. A lead screw 710 is rotatably connected to the top of the guide rail 700. A traction mechanism 800 for pulling the C-shaped rod 630 is screwed on the outer side of the lead screw 710.

[0034] Specifically, the cleaning frame 600 containing the cutlery plates is placed from one end of the cleaning chassis 100 by means of the trolley 500, the traction mechanism 800 pulls the cutlery plates to adjust their positions in the vertical direction, the screw rod 710 rotates to drive the traction mechanism 800 to move the cutlery plates in the horizontal direction, so that the cutlery plates can be initially rinsed off food residues through the filter residue trough 200, and the stubborn dirt on the cutlery plates can be fully cleaned through two frequencies of ultrasonic waves, and the cleaning efficiency can be further improved by rinsing through the rinsing trough 400, and finally dried by the drying box 111 and output through the trolley 500, so as to achieve the effect of continuous and automatic cleaning of the cutlery plates.

[0035] like Figure 1 As shown, in this embodiment, two baffle plates 1 130 and three baffle plates 2 140 are hinged between the tops of the two side panels 110, and a baffle plate 3 150 is detachably fixed between the bottoms of the two side panels 110. The baffle plates 1 130 and 140 can shield the clean slots at different positions to prevent the cleaning liquid or water from splashing out. The baffle plate 3 150 is convenient for protecting the cleaning auxiliary components such as the water pump and the ultrasonic generator 310 inside the cleaning chassis 100. The cleaning chassis 100 and the cart 500 are both installed with self-locking universal wheels in the prior art at the bottom to facilitate the movement of the cleaning chassis 100 and the cart 500.

[0036] like Figure 2 As shown, in this embodiment, a motor 121 for driving the screw rod 710 to rotate is embedded and fixed on the top of one side panel 110, and a drying box 111 is embedded and fixed on the top of the other side panel 110. The drying box 111 is connected and fixed to the air outlet of an external dryer.

[0037] In this embodiment, the output end of the motor 121 drives the screw rod 710 to rotate forward and reversely so that the traction mechanism 800 screwed together with the screw rod 710 can move back and forth linearly on the guide rail 700, thereby enabling the cleaning frame 600 to transfer the cutlery tray to different clean slots. The external dryer delivers hot air to the drying box 111, and the hot air blows toward the cutlery tray through the mesh holes on the drying box 111, thereby facilitating the drying of the cleaned cutlery tray.

[0038] like Figure 3 As shown, in this embodiment, a rectangular water pipe 210 is installed and fixed on the top of the filter residue tank 200 and the flushing tank 400, and a plurality of spray pipes 211 are fixed and connected to the outside of the rectangular water pipe 210 at equal intervals, and a water nozzle is fixed and installed inside the spray pipe 211. The rectangular water pipe 210 is connected and fixed to the water outlet of an external water pump through a pipeline.

[0039] In this embodiment, the water pump pumps external cleaning liquid or water into the rectangular water pipe 210 through a pipe, and then sprays it onto the cutlery tray inside the cleaning frame 600 through nozzles on multiple spray pipes 211 to achieve a showering effect.

[0040] As Figure 3 shown, in this embodiment, filter screens are detachably and fixedly installed at the inner bottoms of the filter residue tank 200, the ultrasonic cleaning tank 300, and the rinsing tank 400. A water receiving box is fixed to the bottom of the filter screen, and a drain pipe is fixedly connected to the bottom of the water receiving box. Water inlet pipes 220 are fixedly connected to the bottoms of the filter residue tank 200, the ultrasonic cleaning tank 300, and the rinsing tank 400.

[0041] In this embodiment, the water inlet pipes 220 facilitate the delivery of water or cleaning liquid into the tanks. The filter screens can filter food residues, facilitating the removal of the filter residues. The water passing through the filter screens can be collected inside the water receiving box below the filter screens, and then the valve of the drain pipe on the water receiving box is opened to facilitate the discharge of the dirty water after cleaning from the cleaning tank.

[0042] As Figure 8 shown, in this embodiment, a water receiving hopper 510 is fixed to the top of the support frame. Two support rods 520 are fixed inside the water receiving hopper 510. The support rods 520 are in contact with the bottom of the outer frame 610. The water receiving hopper 510 facilitates the collection of water and impurities falling from the tableware tray, and the support rods 520 serve to support the cleaning frame 600.

[0043] As Figure 6 shown, in this embodiment, two peripheral rods 640 are sleeved and fixed on the outside of the outer frame 610. Arc-shaped rods 631 are embedded and fixed at both ends of the U-shaped rod 630. The peripheral rods 640 prevent the tableware tray from falling off the cleaning frame 600, and the arc-shaped rods 631 facilitate the hanging of the U-shaped rod 630 by the hook 831.

[0044] During specific implementation, the tableware tray to be cleaned is placed inside the cleaning frame 600, and the cleaning frame 600 is placed on the trolley 500. The trolley 500 is used to transfer the cleaning frame 600 and the tableware tray into the interior of the cleaning machine case 100. The lead screw 710 rotates to drive the traction mechanism 800 to move to the cleaning frame 600. The electric push rod 820 drives the hook 831 to move downward to one side of the arc-shaped rod 631 on the cleaning frame 600. The lead screw 710 drives a plurality of hooks 831 to move and hook onto the arc-shaped rod 631. The electric push rod 820 contracts in length to longitudinally move the cleaning frame 600, and in cooperation with the rotation of the lead screw 710, the cleaning frame 600 moves horizontally, so that the cleaning frame 600 drives the tableware tray to successively move to the filter residue tank 200 to wash the food residues, move to the ultrasonic cleaning tank 300 to fully clean stubborn dirt with two frequencies of ultrasonic waves, move to the rinsing tank 400 for further rinsing, and finally move to the front side of the drying box 111. The drying box 111 dries the cleaned tableware tray, and the traction mechanism 800 releases the cleaned tableware tray and the cleaning frame 600 onto the trolley 500 for delivery out.

[0045] Embodiment 2, based on Embodiment 1, is to enable the cleaning frame 600 containing the cutlery tray to be pulled into the cleaning tanks at different positions for cleaning.

[0046] like Figure 5 and Figure 6 As shown, in this embodiment, the traction mechanism 800 includes a movable seat 810 screwed together with the screw rod 710, the movable seat 810 is slidably connected to the guide rail 700, electric push rods 820 are fixed at both ends of the bottom surface of the movable seat 810, a connecting rod 830 is fixed at the output end of the electric push rod 820, and hooks 831 are fixed at both ends of the connecting rod 830.

[0047] Specifically, when using the traction mechanism 800 to suspend the cleaning frame 600, the screw rod 710 is first rotated to allow the two electric push rods 820 to move with multiple hooks 831 to the top of the cleaning frame 600, and then the output end of the electric push rod 820 is extended to arrange the hook 831 on one side of the arc rod 631, and then the screw rod 710 continues to move the two electric push rods 820 horizontally to move the hooks 831 at different positions to the bottom of the arc rod 631, and finally the output end of the electric push rod 820 is shortened to move the hook 831 upward to suspend the arc rod 631, thereby suspending the entire cleaning frame 600.

[0048] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0049] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
