Description

A washing method of a dishwasher and a dishwasher using the method

technical field

The invention relates to a dishwasher and a washing method for the dishwasher, in particular to a washing method for a fully automatic dishwasher controlled by a computer board, and a dishwasher using the method.

Background technique

The dishwasher integrates the functions of dishwashing, disinfection, drying and storage. It not only changes the traditional manual washing method, but also has the advantages of beautiful appearance, convenient use, time-saving, labor-saving, clean and hygienic, and no special installation. It is becoming more and more popular. The more favored by the majority of consumers. The working principle of the dishwasher is to drive the washing pump through the motor to make the washing liquid spray out from the shower under a certain pressure to form a three-dimensional dense hot water flow. The shower rotates due to the reaction force of the spray water, so that The washing liquid is evenly sprayed on the tableware in the dishwasher, and the tableware is sprayed and rinsed and brushed in a three-dimensional manner. There are many kinds of spray washing methods for dishwashers, but at present the most concerned are the cleanliness of dishwashers and water and energy saving issues.

Chinese patent 98221424.3 discloses a dishwasher. This kind of dishwasher improves the nozzles and nozzles of traditional dishwashers, avoiding the crossing of water flows from each nozzle and wasting water, saving water to a certain extent. , and improved cleanliness. But this kind of dish washing machine also has problem, and it has only one layer of dishwashing frame, and the amount of water used for each washing is the same, and only a small amount of bowls need to be washed, and this kind of mode still consumes more water.

In view of the above problems, Chinese patent 99221217.0 proposes a layered control type dishwasher, which divides the dishwashing rack into upper and lower layers, and correspondingly sets two upper and lower sprayers and two water delivery pipelines, A solenoid valve was installed in one of the water delivery lines. When the tableware is less, the tableware can only be placed on one layer of tableware rack, only the tableware on this layer of tableware rack is cleaned, and the electromagnetic valve in the output waterway of the other sprayer is closed, and when the upper and lower two When tableware is placed on the layer tableware rack, the electromagnetic valve is opened, and the upper and lower showers work simultaneously. In this way, when there are fewer tableware, the water consumption is relatively less.

But this scheme still has certain problems, because its electromagnetic valve only fixedly controls the waterway of a sprinkler, so also can only be fixed on a certain layer when washing single layer, brings inconvenience to the user, and when both the upper and lower layers need washing , The upper and lower sprinklers work at the same time, and the water consumption is large.

In addition, there is a problem in the above technical solution and other solutions in the prior art, that is, the problem of the decomposition time of the detergent on the oily stains on the tableware is not considered. After the detergent is sprayed onto the tableware, it takes a certain amount of time for the detergent to decompose the oil stains on the tableware. Only when the oil stains are fully decomposed and then rinsed can the oil stains on the tableware be fully cleaned. The washing method in the prior art is to rinse the tableware continuously, so that the detergent has no time to fully decompose the oil stains, thereby reducing the degree of cleanliness; to improve the degree of cleanliness, it is necessary to rinse the tableware for a long time, thus increasing the reduced water consumption. In addition, the degree of cleanliness of the tableware and the amount of water used for washing are also related to the spraying intensity of the shower. The greater the intensity of the spraying, the higher the degree of cleanliness and the relatively less water consumption. However, the existing technology does not take measures to increase the spraying intensity of the sprinkler. Even if a booster pump is used, the water pressure from the water pipe to the nozzle is fixed, and the water spraying intensity of the nozzle cannot be further increased, which also leads to poor cleanliness. decrease and increase in water consumption.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned problems in the prior art and provide a new washing method, which can wash any layer in the dishwasher, so that the detergent can have time to fully decompose the oil stains, and Improve the spraying intensity of the washing water flow, improve the cleaning degree, and save water consumption; another object of the present invention is to provide a dishwasher using the above method.

The washing method of the present invention is as follows: the tableware rack of the dishwasher is divided into upper and lower layers, each layer is equipped with a washing shower, and an external water pipe is divided into two washing waterways through the washing pump, and the two waterways are respectively connected to the washing machine of each layer. The sprinkler is characterized in that: a waterway control mechanism is set in the washing pump, the waterway control mechanism can close any one of the two waterways, or open the two waterways at the same time, and the computer board is used to control the When washing any one layer of the two-layer tableware rack, the computer board controls the water channel control mechanism to open the water path of the layer and close the water path of the other layer of tableware rack.

When only one layer needs to be washed in the two-layer tableware rack, the water path of this layer is opened all the time, and the water path of the other layer of tableware rack is closed all the time until the washing time set.

When the two layers of tableware racks need to be washed, the two waterways can be turned on or off in turn, that is, when the first waterway is opened, the second waterway is closed; after a certain time interval, the second waterway is opened, and the first waterway is closed at the same time, and so on. Alternately, pulse washing is achieved until the set washing time.

When both the two layers of tableware racks need to be washed, the two water channels can also be opened at the same time until the set washing time.

In the washing method of the present invention, the time required for the waterway control mechanism to open the first waterway and the second waterway or to open the two waterways at the same time can be set as T1, T2, and T3 respectively, and T1, T2, and T3 are set to be unequal to each other. According to the time required to open the waterway, the board judges which waterway is connected, or the two waterways are opened at the same time, so as to control the dishwasher to wash the upper layer or the lower layer, or wash the upper and lower layers at the same time, or pulse washing in which the upper and lower layers are washed in turn. .

When the two waterways are all opened, the water pressure in the water pipe is released by the outlet of the two waterways, that is, the nozzle of the shower. According to the method of the present invention, when only one layer is washed, the other layer is closed due to the Therefore, the water pressure in the water pipe is completely concentrated on the outlet of the opened waterway, so the spray intensity is increased, and the cleaning effect on the tableware is also increased accordingly; moreover, since a waterway is closed, the water consumption is reduced. And by increasing the spray intensity of the nozzle, the tableware can be washed in a shorter time, so not only saves water consumption, but also shortens the running time of the dishwasher and saves electricity.

Using the above method, when both layers need to be washed, since the water channels of the two layers are opened alternately, for each layer, when the water channels of this layer are opened, the washing principle is the same as that of the single layer washing above, and can pass Increase the spraying intensity of the nozzle to increase the cleanliness and save water; moreover, when spraying water and detergent on one layer, it will stop spraying water on this layer for a certain period of time, while spraying water and washing on the other layer will stop here. During the time of spraying water, the detergent will fully decompose the oil stains on the tableware. After a certain period of time, spray water on the layer again. At this time, the decomposed oil stains will be easily washed away. This makes it easier to wash the dishes and uses less water than rinsing them continuously. In this way, the two layers are washed alternately, and the result is that the degree of cleanliness is improved, and the total water consumption is greatly reduced.

According to another object of the present invention, there is provided a dishwasher using the above method, which includes a cabinet, an inner tank, upper and lower tableware racks, upper and lower showers, dishwasher filters, drain pumps, and washing pumps , the output of the washing pump has two washing water channels, and the two water channels are respectively connected to the sprinklers on the upper and lower floors. The water sheet can close any one of the two waterways.

The pulsator is controlled by the computer board of the dishwasher. The pulsator includes a casing, a drive motor, a drive gear, a drive shaft, a water separator, and a time control gear. There are also drive end inserts and signal end inserts on the pulsator. 1. Common end insert, where the common end insert is connected to the power supply, the driving end insert and the signal end insert are connected to the computer board; one end of the drive shaft is connected to the water diversion plate, and the other end is connected to the time control gear, which can be driven by the time control gear Rotation; the drive gear meshes with the teeth of the time control gear; the drive motor can drive the drive gear to rotate, the drive gear drives the time control gear to rotate through the meshing between the gears, and the time control gear drives the drive shaft to rotate, thereby driving the water separator to rotate.

The water dividing sheet is located at different positions during the rotation process, so that different waterways can be closed and another waterway can be opened, or two waterways can be opened simultaneously. Set the time required to open different water channels or open two water channels at the same time during the rotation of the water separator.

There is also a pulse switch on the pulser, which is connected with the signal terminal of the pulser. Set the state of the pulse switch to be off when the water diversion plate is in the position of opening one waterway or opening two waterways at the same time, and the state of the pulse switch is closed when the water diversion plate is in other positions. When the water diversion sheet is rotated from the beginning to opening one of the waterways, or when two waterways are opened simultaneously, it will take a certain period of time. During this period of time, the pulse switch is also turned off from the initial state. A pulse switch transmits the timing signal required for this process to the computer board. Since the time required for the water diversion plate to rotate and conduct different waterways is different, the time required for the pulse switch to turn off from the initial state is also different. The computer board can judge the pulse switch from the initial state to the time required to disconnect. Which waterway is turned on, so as to control the dishwasher to wash the upper layer or the lower layer, or wash the upper and lower layers at the same time, or pulse washing.

When it is only necessary to wash one of the tableware racks, the computer board controls the water diversion plate to turn to the position of opening the water channel of this layer and no longer rotates. The water channel of this layer is always open, while the water channel of the other layer is always closed until the setting washing time.

When both layers need to be washed, the computer board can open or close the two waterways in turn according to the above judgment method, that is, when the first waterway is opened, the second waterway is closed; after a certain time interval, the waterway two is opened and closed at the same time Waterway 1, this cycle alternates to realize pulse washing until the set washing time.

Of course, when the two layers of tableware racks need to be washed, the water separator can also be rotated to the position where the two water channels are opened simultaneously, and the upper and lower sides are washed at the same time until the set washing time.

The dishwasher using the above method can not only wash any layer in the dishwasher alone, but also alternately wash the upper and lower layers in a pulsed manner or wash at the same time, and can increase the spraying intensity of the washing water to improve the cleaning efficiency. Clarity, shorten washing time, save water and electricity consumption.

Detailed ways

As shown in Fig. 1, the dishwasher of the present invention comprises a casing 1, an inner container 2, an upper cutlery rack 3, a lower cutlery rack 4, an upper shower 5, a lower shower 6, a dishwasher filter 7, a drain Pump 8, washing pump 9, the water in the external water pipe is pressurized by the washing pump 9 and enters the waterway of the dishwasher. After the external water pipe enters the washing pump 9, it is divided into two washing waterways, i.e. waterway one and waterway two. The first waterway 10 is connected to the upper sprinkler 5 on the upper floor, and the second waterway 11 is connected to the lower shower 6 on the lower floor. In the washing pump 9, a pulser 12 is installed, and the pulser 12 is controlled by a computer board. There is a water dividing sheet on the pulser 12, and any one of the two waterways can be closed by the water dividing sheet.

In order to make the washing more uniform and prevent the blind area of water spraying, the present invention can also set a top sprayer 14 on the top of the dishwasher; and divide the waterway 10 into two paths through a water distribution pipe 13, and connect the top sprayer respectively. Device 14 and upper shower 5.

Above-mentioned pulser 12 is controlled by the computer board of dishwasher. The structure of the pulser 12 is shown in Figure 3. The pulser includes a housing 15, a drive motor 16, a drive gear 17, a drive shaft 18, a water diversion plate 19, and a time control gear 20. The pulser 12 also has a drive end insert 21, a signal End insert 22, public end insert 23, wherein common end insert 23 is connected with power supply, driving end insert 21 and signal end insert 22 are connected with computer board; One end of drive shaft 18 is connected with water diversion plate 19, and the other end is connected with time The control gear 20 is connected and can be driven by the time control gear 20 to rotate; the drive gear 17 meshes with the time control gear teeth 20; the drive motor 16 can drive the drive gear 17 to rotate, and the drive gear 17 drives the time control gear 20 to rotate through the meshing between the gears , the time control gear 20 drives the drive shaft 18 to rotate, thereby driving the water diversion plate 19 to rotate.

The position indicator 24 of the water diversion plate can be set on the pulser shell, and the position of the water diversion plate 19 when opening the waterway one, the waterway two and opening two waterways at the same time corresponds to the positions of A, B and A+B on the indicator respectively.

The water dividing sheet 19 is located in different positions during the rotation, and one waterway can be closed and another waterway can be opened, or two waterways can be opened simultaneously. The time required to open different waterways or to open two waterways simultaneously is different during the rotation process of the setting water dividing plate 19 .

There is also a pulse switch 25 on the pulser, which is connected with the signal terminal 22 of the pulser, so that the signal can be transmitted to the computer board 26 through the signal terminal. Fig. 4 is a schematic diagram of the circuit connection structure of the pulser switch. It is set that when the water diversion plate is in the position where one waterway is opened, or two waterways are opened simultaneously, the state of the pulse switch 25 is off, and when the water diversion plate is in other positions, the state of the pulse switch is closed. When the water diversion sheet is rotated from the beginning to opening one of the waterways, or when two waterways are opened simultaneously, it will take a certain period of time. During this period of time, the pulse switch 25 is also turned off from the initial state (the initial state may be closed or open). Pulse switch 25 transmits the required time signal of this process to computer board 26. Because the water diversion sheet rotates and conducts different waterways, the required time is different, and the pulse switch is also different from the initial state to the time required for disconnection. The computer board 26 can be used according to the pulse switch. Judging which waterway is connected, so as to control the dishwasher to wash the upper layer or the lower layer, or wash the upper and lower layers at the same time, or pulse washing.

As shown in Figure 5, when the water diverter plate is turned to position A, the first water channel of the dishwasher is turned on, and the second water channel is closed; when the water diverter plate is at position B, the second water channel is turned on, and the first water channel is closed; When +B, both waterway 1 and waterway 2 are connected. When the water diverter is rotated to the positions of A, B, and A+B, the time from the initial state to the disconnection of the corresponding pulse switch is T1, T2, and T3 respectively, and the settings of T1, T2, and T3 are not equal to each other. For example, T1, T2, and T3 can be set to any value within 1 to 10 seconds, but T1, T2, and T3 are different. In the embodiment to be described below, T1 = 1.75 seconds, T2 = 3.15 seconds, and T3 = 7.05 seconds are set.

Embodiment 1: top wash

When there is only one layer of tableware on the tableware rack, if only the upper layer has tableware, only this layer should be washed. At this time, the computer board should control the water diversion plate to close the water channel 2, and only open the water channel 1, and the water diversion plate should stay at the A position.

Turn on the power of the dishwasher, select the upper washing button on the control panel, the computer board sends instructions to the driving motor 16 of the pulser, the driving motor 16 drives the driving gear 17 to rotate, and the driving gear 17 drives the time control gear 20 through the meshing between the gears Rotate, thereby drive water diversion piece 19 to rotate. Assuming that the current pulsator water splitter 19 is in any position, the state of the pulse switch 25 may be open or closed. If the pulser needs to stop at the A position now, the drive motor 16 is supplied with power, and the pulsator water splitter 19 is turned on. Rotate, when reaching T (1 or 2 or 3) position for the first time, the state of pulse switch 25 is disconnected, continue to rotate now, the state of pulse switch 25 changes into closing by disconnection, starts counting time now, when switch When the time from closing to opening is T1=1.75 seconds, it can be judged that the water separator is in position A, and stop supplying power to the driving motor; if the time from closing to opening of the switch is not 1.75 seconds, continue to supply power to the driving motor until until this state occurs. At this time, the water diverter of the pulsator is in position A, and the waterway is turned on.

Since one waterway is closed and only one waterway is turned on, the water pressure in the two waterways is basically completely released from the nozzle of the upper sprinkler, so the water spraying intensity at the nozzle is increased, and the cleaning ability of the tableware is enhanced, not only The degree of washing is increased, and the dishes can be washed in a shorter time, shortening the washing time, saving electricity and reducing water consumption. Moreover, since only one waterway is used to discharge water, the amount of water used is further reduced.

It should be noted that the closure of a certain waterway in the present invention may not be completely closed, and a small amount of water may still be allowed to flow through, so as to prevent the heater from running dry. "Close" described in the following embodiments has the same meaning.

Embodiment 2: lower layer washing

When only the lower layer needs to be washed, the computer board controls the pulsator water diversion piece to close waterway 1 and waterway 2 to open, and the waterway piece should stay at position B.

Select the lower floor washing button on the control panel, and the computer board sends instructions to the driving motor of the pulser to rotate the water separator of the pulser. The principle is the same as that described in the above-mentioned embodiment, assuming that the current state of the water separator of the pulsator is in any position, the state of the pulse switch may be open or closed. If the pulsator needs to stop at position B, firstly The water sheet rotates and continues to rotate when it reaches the T (1 or 2 or 3) position. The pulse switch changes from off to on. At this time, the time starts to be counted. When the time from closing to off of the switch is T2 = 3.15 seconds, It can be determined that the water diverter is in position B, then stop supplying power to the driving motor, if the time from closing to opening of the switch is not 3.15 seconds, continue supplying power to the driving motor until this state occurs. At this time, the water diverter of the pulsator is located at position B, and the second water channel is turned on.

The washing principle is the same as in Example 1. Therefore, the present invention can wash any one of the upper and lower layers separately.

Example 3: Pulse Wash

When both layers need to be washed, the dishwasher of the present invention can adopt the pulse washing method, that is, the upper and lower layers are washed in turn, and the upper layer is washed for a certain period of time, then the lower layer is washed for a certain period of time, and then the upper layer is washed for a certain period of time, and so on. to set the washing time.

At this time, the computer board needs to control the water diversion plate of the pulsator to close the waterway one or waterway two in turn according to the set time interval, that is, the water diversion plate should be located at position A or position B in turn. When the water diversion plate is located at A, when the water channel two is closed, the water channel one is opened, and the upper floor shower sprays water and detergent to the tableware on the tableware rack on the upper floor. After a certain period of time, the computer board controls the water diversion plate to rotate to position B, and the first water channel is closed, while the second water channel is opened to spray water on the tableware rack on the lower floor for washing. The way in which the computer board controls the location of the water-distributing sheet at A or B is the same as that of the above-mentioned embodiment 1 and embodiment 2. When the upper shower stops spraying water and starts to wash the lower layer, the detergent on the tableware on the upper layer adheres to the surface of the tableware and decomposes the oil stain on the surface of the tableware. After a certain period of time, the second waterway is closed again. During the interval of being closed, the detergent on the lower tableware has time to fully decompose the oil stains on the lower tableware; It is fully decomposed, and the water sprayed from the upper shower can easily wash away the oil stains and other sundries on the tableware. After a certain period of time, the second water channel is opened again to wash away the oil stains and impurities on the lower tableware. The upper and lower waterways are opened and closed alternately in this way to realize pulse washing. As a result, the spray intensity of each layer of waterway is increased when the waterway is opened. Moreover, this pulse washing method also allows the detergent to have sufficient time to decompose the oil stains on the tableware. Compared with the washing method of continuously rinsing the tableware, it is easier to clean the tableware and consume less water.

The above washing method and the dishwasher adopting this method change the simultaneous washing of the upper and lower layers of the original dishwasher into pulse washing, which can increase the spray intensity of single-layer washing, so that the cleaning rate can be improved, and it can reach European A-level The cleaning rate is high, and at the same time, due to the reduction of water consumption, energy consumption can be reduced, so it can reach European A-level energy consumption.

The time interval of the above-mentioned pulse washing can be set in advance and solidified into the control program of the computer board. Various washing methods and washing times can be set according to the type and degree of oil stains on the tableware. For example, the time interval of pulse washing can be set The total washing time can be set between 30 seconds and 2 minutes, and the total washing time can be set between 4 minutes and 20 minutes, which can be selected by the user during washing according to the needs. As in the above example, if the time interval for washing the upper and lower layers is set to 1 minute, and the total washing time is 8 minutes, after the washing starts, the dishwasher first washes the upper layer for 1 minute, then stops spraying water on the upper layer, and then washes the lower layer for 1 minute. , so that the cycle is alternated until the set washing time is 8 minutes.

Of course, when both the upper and lower layers need to be washed, the dishwasher of the present invention can still open the two waterways simultaneously, and the upper and lower layers can be sprayed and washed simultaneously. At this time, the water splitter needs to stop at the A+B position. The computer board sends instructions to the drive motor of the pulser to rotate the water separator of the pulser. The principle is the same as that described in the above-mentioned embodiments, assuming that the current state of the water separator of the pulsator is in any position, the state of the pulse switch may be open or closed. If the pulsator needs to stop at the A+B position, first pulse The water divider rotates, and when it reaches the T (1 or 2 or 3) position, it starts to count the time. When the time from the state of starting the timing to the disconnection of the switch is T3=7.05 seconds, stop supplying power to the drive motor. If the switch If the time from closing to opening is not 7.05 seconds, continue to supply power to the drive motor until this state occurs. At this time, the water diverter of the pulsator is located at the A+B position, the first water channel and the second water channel are turned on at the same time, and the upper and lower layers are washed at the same time.
