The upper part of the coupling 10 is connected to the center point of the rotating shaft 8, the lower part of the coupling 10 is connected to the power shaft of the motor 7, and the motor 7 is connected to the control device 2. When washing dishes, the rotation of the motor 7 directly drives the rotation of the shaft 8 to agitate the water to produce vortex water flows in different directions. The tsunami-like water washes the tableware comprehensively, which accelerates the shedding of greasy adherents on the tableware and makes cleaning more In place. When the angle between the impeller 9 and the rotating shaft is 60°, the vortex flow generated is the largest, and the dishwashing effect is the best.
[0031] A water inlet valve 11, a drain valve 12 and a water level sensor 13 are also installed in the cabinet 1. The water inlet valve 11 is located at the upper part of the washing chamber 3 and is fixedly connected to the water inlet pipe 5, and the drain valve 12 is located at the bottom of the washing chamber 3 and is fixedly connected to the water outlet pipe. 6. The water level sensor 13 is located in the middle of the washing chamber 3, and the water inlet valve 11, the drain valve 12 and the water level sensor 13 are respectively connected to the control device 2. When the water inlet valve 11 is opened to fill water, the water level sensor 13 will monitor the water level in the washing chamber 3 in real time. If the water level reaches the preset height, the control device 2 controls the water inlet valve 11 to close; when the drain valve 12 is opened to discharge water, The sewage in the washing chamber 3 has been completely discharged, and the control device 2 controls the inlet and outlet valves 12 to close.

[0033] A heating device 17 is also provided on the inner wall of the washing chamber 3. The heating device 17 is an “M-shaped” stainless steel tubular electric heating element, and the heating device 17 is connected to the control device 2. The heating device 17 is installed next to the inner tank of the machine and directly contacts the water for heating, so the heat efficiency is high.
[0034] A support 18 is installed at the bottom of the washing cavity 3, and the bowl 4 is fixedly placed on the support 18. This placement structure makes the bowl 4 more stable and will not move due to the impact of strong water flow when washing dishes. The structure of this pulsator dishwasher is relatively simple, so the cost will be relatively cheap, and the price will be more reasonable, so that more domestic families can afford it.
[0035] Refer to image 3 As shown, the working process of the control method of the pulsator dishwasher includes the following steps:
[0036] (a) Water injection: When the cleaning starts, the water inlet valve 11 is opened to inject clean water into the washing chamber 3, and the water level sensor 13 monitors the water level in the washing chamber 3 in real time. When it is monitored that the water is filled to the preset height, the water inlet valve 11 is closed , The water injection is over. There are minimum and maximum water level height lines in the washing chamber 3. The water level height shall not be lower than the minimum water level line or higher than the maximum water level line each time water is filled. The water level height preset in the control device 2 is the minimum water level line and the maximum water level The middle height of the line.
[0037] (b) Heating: The heating device 17 heats the water in the washing chamber 3. When the water temperature reaches the preset value, the heating device 17 stops heating. The preset heating water temperature in the control device 2 is 80℃, which can be effectively softened by increasing the water temperature The oil stains on the tableware can shorten the cleaning time, and can be cleaned more cleanly and more efficiently.
[0038] (c) Soaking: The tableware is soaked in clean water after heating, and the soaking time is a preset time. The preset soaking time in the control device 2 is 10 minutes, which can further soften the oil stains on the tableware and make it easier to wash off.
[0039] (d) Rinse: Rinse the tableware at a preset time, and the preset rinsing time in the control device 2 is 10 minutes. During rinsing, the rotation of the motor 7 directly drives the rotating shaft 8 to rotate, agitating the water to generate vortex water currents in different directions, and the water like a tsunami washes the tableware comprehensively, accelerating the shedding of greasy adherents on the tableware, and making the rinsing more in place. After the rinsing is completed, the sewage is discharged from the washing chamber 3 until completely discharged.
[0040] (e) Cleaning: Open the water inlet valve 11 and inject clean water into the washing chamber 3 to a preset height. The preset water level in the control device 2 is the middle height between the lowest water level and the highest water level. If you are worried that a small amount of residue will remain at the bottom of the washing chamber 3 when draining, you can set the drain valve 12 to remain open for a certain period of time when the water inlet valve 11 is opened to fill water. The control device 2 presets the drain valve 12 in the water inlet valve 11 After opening, keep it open for 2 minutes, so that the injected water washes away the residue, and then close the drain valve 12 after 2 minutes. The motor 7 works at a preset time. When water is poured into the heating device 17, the heating device 17 starts to heat to a preset temperature, and the preset heating temperature in the control device 2 is 40°C. The control device 2 presets each cleaning time of 5 minutes. The motor 7 directly drives the rotating shaft 8 to rotate to agitate the water to produce vortex water flows in different directions. The water washes the tableware completely like a tsunami and removes a small amount of the tableware. Residual stains and a small amount of detergent make cleaning more clean. After the cleaning is completed, the sewage is discharged from the washing chamber (3) until completely discharged, and the step (e) is repeated to perform a second cleaning to make the tableware more in place.
[0041] (d) Drying: After the cleaning is completed, the hot air blower 15 is turned on to send hot air into the washing chamber 3, and at the same time, the exhaust fan 16 is turned on to extract the moisture in the washing chamber 3 to complete the tableware drying process. This method of simultaneously working hot air and dehumidifying can accelerate the drying of tableware, and at the same time, this high-temperature drying process can also achieve the effect of disinfection.
[0042] Before step (a), there is step (a0) to set the time of each step: the operator can set the time of each step of the pulsator dishwasher before washing the dishes according to the number of dishes put into the dishwasher each time Working hours and whether heating is required. For daily dishwashing, the control device 2 is preset to control the working time and heating state of each step, and it can be started directly after turning on the power of the dishwasher. If you want to automatically reset the working time and heating state of each step, you can also set it in the control device 2. If there are more tableware to be cleaned, you can increase the time of step (c) soaking, step (d) rinsing and step (e) cleaning, set the soaking time of step (c) to 15 minutes, and the time of step (d) rinsing It is set to 15 minutes, and the cleaning time of step (e) is set to 10 minutes.
[0043] In steps (d) and (e), the motor 7 rotates clockwise and counterclockwise alternately, so that the motor 7 rotates and agitates the water to generate vortex water flows in different directions, so that the tableware is washed more comprehensively.
[0044] The entire dishwashing process is controlled within 1 hour, plus drying, the whole process does not exceed 1.5 hours, which is more time-saving than traditional dishwashers. The immersion dishwashing method of the pulsator dishwasher saves more water than the jet water jet dishwashing method of the traditional dishwasher. Therefore, the energy consumption of this dishwasher is better than that of the traditional dishwasher.
[0045] The structure of this pulsator dishwasher is relatively simple, and all parts are manufactured in China, so the cost will be relatively cheap, so the price is more reasonable, and the maintenance is convenient, so it is more suitable for ordinary domestic households.
[0046] The specific usage of this embodiment is as follows:
[0047] First clean up the food residues in the tableware to ensure that no large pieces of food adhere to the tableware, then drop a certain amount of ordinary household detergent on the tableware, and then put the tableware in the bowl 4 in turn, put it in the basket, and push it into the washing Cavity 3, close the door of the box 1. If you want to set the time for each step of washing dishes in advance, you can set it in the control device 2 on the upper part of the box 1. After setting, press the start button, the work indicator lights up, and the dishes are washed When the machine starts to work, the control device 2 will clean the tableware according to a preset process until the operation is completed and the dishwashing work is finished.
