Description

Technical Field

[0001] The present invention relates to the technical field of catering cleaning, and in particular to a catering dishwasher. Background Art

[0002] In order to improve the cleaning effect of tableware, dishwashers are usually equipped with water heating devices. By heating the washing water, the high-temperature washing water can wash away the contaminants on the tableware and bring heat to the tableware. As a result, the dishwasher system can achieve higher cleaning and drying rates in a shorter washing time.

[0003] In the prior art, when the heating device and temperature detection circuit in a dishwasher are both operating normally, the water temperature detected by the temperature detection circuit can be used to determine whether the water temperature has reached a preset water temperature value within a preset heating time. If the water temperature reaches the water temperature value within the preset heating time, the heating and washing process is complete, the heating system stops heating, and the dishwasher enters the next wash process. However, if the water temperature does not reach the water temperature value within the preset heating time, it indicates that the heating device and / or the temperature detection circuit have an abnormality, and the dishwasher immediately interrupts the current wash process and issues an alarm to the user to protect other components of the dishwasher from damage. However, because tableware such as dishes and plates are tilted when placed on the dishwashing rack, the dishwasher's spray nozzle cannot spray the wash water directly into the gaps between the dishes.

[0048] The driving motor 36 drives the mounting rod 37 to reciprocate through the screw-nut mechanism, and the mounting rod 37 drives the cleaning pipe 38 to reciprocate. When the dishes to be cleaned are installed in the dishwashing cavity 111 through the dishwashing rack, the dishes can be cleaned through the cleaning pipe 38.

[0049] like Figure 1 、 7As shown in Figures 8 and 9, the direction adjustment mechanism 4 includes a direction adjustment support platform 41 arranged on the side wall of the dishwashing cavity 111, a platform 411 is provided on the upper surface of the direction adjustment support platform 41 close to the interior of the dishwashing cavity 111, a track 412 is provided on the upper surface of the direction adjustment support platform 41 away from the interior of the dishwashing cavity 111, a limiting platform 42 is provided above the direction adjustment support platform 41, and a direction adjustment limiting groove 421 is provided in the middle of the limiting platform 42.

[0050] A steering block 43 is provided between the steering support platform 41 and the limiting platform 42, and a connecting block 431 is provided on the side of the steering block 43. The connecting block 431 is fixedly connected to the cleaning pipe 38, and a connecting rod 432 is connected to the bottom of the connecting block 431. The end of the connecting rod 432 is rotatably connected to the roller 433. The roller 433 and the steering support platform 41 are in rolling contact. A steering limit rod 436 is connected to the top of the steering block 43, and an steering slider 4361 is provided on the upper end of the steering limit rod 436. The steering slider 4361 cooperates with the steering limit groove 421. A spring 434 is provided on the outside of the direction-adjusting limit rod 436. The lower end of the spring 434 is fixedly connected to the direction-adjusting block 43. The upper end of the spring 434 is fixedly connected to the limit plate 435. The limit plate 435 and the direction-adjusting limit rod 436 are slidably connected. A plurality of circumferentially distributed balls 4351 are provided on the upper surface of the limit plate 435. The balls 4351 are in rolling contact with the lower surface of the limit platform 42.

[0051] When the steering mechanism 4 reciprocates with the cleaning pipe 38, the roller 433 always rolls close to the upper surface of the steering support platform 41 under the action of the spring 434. At this time, the steering block 43 will be deflected as a whole, and then the cleaning pipe 38 will be deflected, so that the water spray pipe 383 can adjust the water spraying direction.

[0052] The working steps are as follows:

[0053] S1. Open the first closed door and place the dishwashing rack along the dishwashing rack chute 113 into the dishwashing chamber 111;

[0054] S2, set dishwashing parameters through control key 15;

[0055] S3, start the pump mechanism 2 to deliver cleaning liquid to the mobile cleaning mechanism 3;

[0056] S4, start the drive motor 36 to make the water spray pipe 383 reciprocate;

[0057] S5, the direction adjustment mechanism 4 reciprocates along the direction adjustment support platform 41, driving the water spray pipe 38 to rotate in the direction adjustment;

[0058] S6. The waste liquid after cleaning is filtered through the screen 17 and the filter tube 19 and then discharged from the dishwashing chamber 111.

[0059] Here’s how it works:

[0060] To operate the dishwasher of the present invention, the user first sets the preset parameters using the control keys 15. A dishwashing rack containing dishes to be washed is then placed along the dishwashing rack chute 113 into the dishwashing chamber 111. The elastic clamps 1131 help secure the rack. The first sealing door 12 is then closed, and the dishwasher is started. Dishwashing liquid flows through the pump mechanism 2 into the cleaning liquid infusion pipe 39. After being pressurized by the booster pump 391, it enters the spray pipe 383, where the sprayed liquid washes the dishes. The movable cleaning mechanism 3 is then activated, driving the cleaning pipe 38 in reciprocating motion via the screw-nut mechanism. During this motion, the steering block 43 of the steering mechanism 4 moves along the track 412, causing the connecting rod 432 to move up and down along the track. This drives the connecting block 431 and the cleaning pipe 38 to rotate, adjusting the spray direction of the spray pipe 383. The radial spray holes 3832 allow the cleaning liquid to be sprayed along the inclined gaps of the dishes when washing dishes, enhancing the cleaning effect. When the cleaned liquid falls to the bottom of the dishwashing chamber 111, the water spray pipe 383 at the bottom can clean the bottom of the dishwashing chamber 111, and the waste water flows into the heating filter tank 114 through the screen 17. The heating rod 18 added to the filter tank 114 can ensure that the temperature in the dishwashing chamber 111 is moderately maintained at a preset value. After the waste water is filtered by the filter tube 19, it is discharged from the heating filter tank 114.

[0061] The beneficial effects are as follows:

[0062] The present invention provides a dishwashing dishwasher, which comprises a dishwashing frame 1, a liquid pumping mechanism 2, a movable cleaning mechanism 3 and a direction adjustment mechanism 4.

[0063] The mobile cleaning mechanism 3 is designed to be able to do reciprocating motion, and the spray holes 3832 on the cleaning pipe 38 are radial, which can ensure that the sprayed liquid can spread all over the dishes to be cleaned.

[0064] The design of the adjustment mechanism 4 works in conjunction with the mobile cleaning mechanism 3. The adjustment block 43 reciprocates along the cleaning pipe 38, moving along the track 412. The spring 434 causes the connecting rod 432 to move up and down along the track 412, driving the connecting block 431 and the cleaning pipe 38 to rotate and adjust the direction of water spray from the water spray pipe 383. The adjustment support 41 can be replaced according to actual conditions, so that the water spray direction of the water spray pipe 383 can be aligned with the tilt direction of the dishes, improving the cleaning effect.
