technical field

The present invention relates to a dish washer which cleans the tableware contained in a washing tank by spraying washing water onto the tableware.

Background technique

Existing household tableware washing machines generally clean objects to be cleaned such as tableware arranged in a tableware basket arranged in a washing tank with washing water by spraying them with washing water. Wherein, in order to allow the washing water to be evenly sprayed onto the many objects to be washed arranged in the tableware basket, the arrangement of the spraying device for spraying the washing water will become very important.

In particular, in a dishwashing machine in which the bottom surface of the washing tank is rectangular, in the case where a multi-layered dish basket is provided in order to load as many items as possible into the washing tank, it is necessary to distribute the washing water evenly. Spray onto the items to be washed in the cutlery baskets in each level. But, the cleaning water sprayed out from below can be blocked by the object to be cleaned in the tableware basket of the lower floor, so the cleaning water cannot be fully sprayed on the object to be cleaned in the tableware basket of the upper floor. As a result, the cleaning performance of the objects to be cleaned contained in the upper tableware basket is reduced. Especially in the case where bowls and other cutlery are arranged in the lower cutlery basket, due to the shape of the bowl cutlery, the spray water from below is almost blocked, and the objects to be cleaned in the upper cutlery basket may not be cleaned. cleaning.

In order to solve this problem, it has been proposed that a plurality of spraying devices are provided in the dishwasher to spray washing water on the object to be cleaned from multiple directions in the washing tank. However, in order to spray washing water from a plurality of spraying devices, the amount of water stored in the washing tank needs to be increased, and the heating time of the washing water becomes longer, and the operating time and power consumption also increase. In addition, when the amount of water increases, a large-scale cleaning pump needs to be installed, which increases the manufacturing cost. In addition, if a large amount of washing water is used, there may be problems such as noise and increased vibration.

In addition, after the number of spray devices increases, the body of the dishwasher will become larger, and the installation space of general household dishwashers, such as between the kitchen console and the wall cabinet, is limited, so it may Compromise the convenience when setting up the product.

For this reason, someone has proposed a dish washer as shown in Japanese Patent Laid-Open Publication 2004-267661. This dish washer is provided with a plurality of injection devices, which can improve the cleaning ability without increasing the The amount of water inflow can prevent the occurrence of the above problems.

The structure of this tableware washing machine is as shown in Figure 6, wherein is provided with the cleaning tank 102 that the bottom surface is rectangular, and is provided with a plurality of injection devices: the bottom in the cleaning tank 102 is provided with rotary cleaning nozzles 103,104, cleaning A fixed cleaning nozzle 105 is provided on the rear wall of the tank 102 . The cleaning water pressurized by the cleaning pump 111 is sequentially switched by the water separating device 115 and sent to the above-mentioned spraying devices 103 , 104 and 105 . In this way, since the washing water is sequentially switched and sent to each of the spraying devices 103, 104 and 105, the washing water can be sprayed on many objects 110 to be cleaned without increasing the water intake.

However, in such existing dishwashers, the upper tableware basket is often set to be left low and right high, that is, the part above the position for setting bowls and other tableware in the lower floor tableware basket (i.e. the upper floor in FIG. 6 The left part of the cutlery basket) is set lower, and the part above the position for setting dishes in the lower cutlery basket (ie, the right part of the upper cutlery basket in FIG. 6) is set higher.

In this case, when the objects to be cleaned 11 installed in the upper tableware basket, especially the objects to be cleaned in the left part of the upper layer tableware basket are cleaned by the fixed cleaning nozzles 105 provided on the rear wall of the cleaning tank 102, When the object to be cleaned 110 is cleaned, a sufficient spray angle cannot be obtained, and sufficient cleaning performance cannot be achieved. At the same time, the fixed cleaning nozzle 105 can only spray cleaning water in a limited range, and the shapes and installation states of the tableware are different, so the cleaning water cannot be evenly sprayed onto the object 110 to be cleaned. As a result, in such conventional dishwashers, there is a problem that sufficient washing performance cannot be achieved.

That is, in addition to the first rotary cleaning nozzle 7, two rotary cleaning nozzles 3 and 4 are provided as the second rotary cleaning nozzle.

In addition, the water conduit unit 21 is provided integrally with the fixed washer nozzle 5 . The right channel in the water guide unit 21 is used as the water guide of the fixed washing nozzle 5, and the left channel is used as the water guide of the first rotating washing nozzle 7 for cleaning the left part of the upper tableware basket 9. In the configuration of the water conduit of the first rotary washer nozzle 7 , the rotary washer nozzle water conduit 6 b extending forward is connected to the horizontal portion left side 6 a of the water conduit unit 21 . In addition, the first rotary cleaning nozzle 7 is provided on the front end portion of the rotary cleaning nozzle water guide pipe 6 b and is located below the left side portion of the upper tableware basket 9 . That is, the first rotary cleaning nozzle 7 is disposed above the object to be cleaned 10 in the lower tableware basket 8 .

In this way, in the dish washer 1 of the embodiment of the present invention, the object to be cleaned 10 installed in the cleaning tank 2 is cleaned from the fixed cleaning nozzle 5, the first rotating cleaning nozzle 7, and the second rotating cleaning nozzle 3,4. Spray cleaning water to clean the object 10 to be cleaned.

As shown in FIG. 2 , a drain port 12 is provided at the bottom of the cleaning tank 2 , and this drain port 12 communicates with the suction side of a cleaning pump 11 that functions as a water pump. The drain port 12 is provided with a leftover filter 13 for collecting leftovers and a heater 14 for heating the washing water. The washing water passing through the leftover residue filter 13 is sucked by the washing pump 11 and pressurized. The pressurized cleaning water is sprayed out from the first rotating cleaning nozzle 7 , the second rotating cleaning nozzle 3 , 4 and the fixed cleaning nozzle 5 through the water distributor 15 .

Next, the operation of the dishwasher 1 having the above-mentioned constitution will be described.

When cleaning the tableware, the user first opens the machine door 16, and loads the object to be cleaned 10 in the lower tableware basket 8 and the upper layer tableware basket 9; Push it into the cleaning tank 2; then, add cleaning agent, and close the machine door 16 on the front opening of the cleaning tank 2. After the machine door 16 is closed, the dishwashing machine 1 starts to work, and performs the cleaning step, the rinsing step and the drying step in sequence.

After the cleaning operation started, the water inlet valve was first operated, and a specified amount of cleaning water was added in the cleaning tank 2, and the added cleaning water was heated by the heater 14. The heated cleaning water is firstly pressurized by the cleaning pump 11, and then sent to the first rotating cleaning nozzle 7, the second rotating cleaning nozzle 3, 4 and the fixed cleaning nozzle 5 through the water dividing device 15. Here, the operation of the water diversion device 15 is to switch the conveying direction of the washing water in the order of the rotating washing nozzle 3 , the rotating washing nozzle 4 , the fixed washing nozzle 5 and the rotating washing nozzle 7 at regular intervals. When each rotating cleaning nozzle 3, 4, 7 sprays the cleaning water from each injection port, it will rotate under the reaction of the jet flow, thereby spraying the cleaning water that moves while rotating, and will be set at The objects to be cleaned 10 in the lower tableware basket 8 and the upper tableware basket 9 are cleaned.

The fixed cleaning nozzle 5 sprays cleaning water from the spray port arranged horizontally below the upper tableware basket 9 to mainly clean the right side of the upper tableware basket 9 . In this way, not only the inner surface of the object to be cleaned 10 disposed downwards on the right side of the upper tableware basket 9 can be cleaned; Under the action of the cleaning water, the outer surface of the object to be cleaned 10 can also be cleaned.

As mentioned above, the arrangement of the objects to be cleaned 10 in the lower tableware basket 8 is that the left part is provided with bowl tableware, and the right part is provided with plate tableware. Since the height of the bowl tableware is lower than that of the plate tableware, When considering the convenience of placing the object to be cleaned 10 in the upper tableware basket 9, the left side part of the upper tableware basket 9 can be arranged at a lower position than the right side part.

Next, the situation when the object to be cleaned 10 contained in the upper tableware basket 9 is cleaned only by the fixed cleaning nozzle 5 arranged on the rear wall of the cleaning tank 2 will be considered. In this case, since the left part of the upper cutlery basket 9 is set at a lower position, it is difficult to obtain a sufficient spray angle when cleaning the object 10 from the fixed cleaning nozzle 5, and the lower part is arranged on the lower level. The bowl cutlery in the cutlery basket 8 will constitute an obstacle, and it is difficult to count on the supply of washing water from below. In addition, the left part of the upper cutlery basket 9 is used as a space for placing miscellaneous objects 10 of different shapes due to the high space height, and the fixed cleaning nozzle 5 can only spray at a predetermined angle within a certain range. Therefore, for the objects to be cleaned 10 having different shapes and installation postures in the left part of the upper tableware basket 9, effective cleaning cannot be performed.

For this reason, in the dish washing machine 1 of the present embodiment, in order to ensure the cleaning performance of the object to be cleaned 10 contained in the upper tableware basket 9, the bottom of the left side of the upper tableware basket 9 or in the lower tableware basket A first rotating cleaning nozzle 7 is arranged above the object to be cleaned 10 in 8 .

When the height of the body of the dishwasher 1 is limited to a certain level in order to ensure the installation of the dishwasher 1, there is no place to install the dishes under the right part of the upper tableware basket 9 because the dishes with a higher installation height are arranged. Space for swivel cleaning nozzles. But, because the object to be cleaned 10 in the tableware basket 9 on the upper level is contained in a higher position, the fixed cleaning nozzle 5 that is located on the rear wall of the cleaning tank 2 can obtain a sufficient spray angle; Depending on the shape of the plate-like tableware on the top, the cleaning water can be sprayed from the bottom. In addition, since the right part of the upper tableware basket 9 is a space for setting cylindrical tableware such as cups and tea bowls with a low height, the installation posture and the shape of the tableware are relatively fixed to a certain extent, so the fixed cleaning nozzle 5 can also be used. Guaranteed cleaning performance.

Next, the impact on the installation of the object 10 to be cleaned after adding the first rotary cleaning nozzle 7 will be described. The rotary cleaning nozzle 7 is provided so as to extend from the water guide pipe provided on the wall surface of the cleaning tank 2 to the center of the cleaning tank 2 . In this way, the first rotary washing nozzle 7 is in a state extending from the rear to the front in the washing tub 2 . With this configuration, by arranging the water guide pipes in the front-rear direction, there is no obstacle when the objects to be cleaned 10 are installed, and the objects to be cleaned 10 are very convenient to install.

The cleaning water sprayed from each rotating cleaning nozzle 3, 4, 7 in the cleaning tank 2 and from the fixed cleaning nozzle 5 flows down to the bottom of the cleaning tank 2 after cleaning the object 10 to be cleaned; It is collected by the drain port 12 and heated again by the heater 14; then, it flows through the leftover residue filter 13, and is sent to each rotary cleaning nozzle 3, 4, 7 and fixed cleaning by the cleaning pump 11 through the water dividing device 15 again. Nozzle 5. When the washing water is sprayed, leftovers falling off from the object 10 to be cleaned are captured/collected by the leftover filter 13 . In addition, the temperature of the washing water is detected by the temperature sensor 17, and when it exceeds a predetermined temperature, the energization of the heater 14 is stopped, so that the washing water can always be maintained at a temperature suitable for washing.

After the cleaning step has been carried out for a specified time, the cleaning water containing dirt is discharged from the drain pump 18 to the outside of the machine, and new cleaning water is added in the cleaning tank 2 . The added cleaning water is sprayed out from the rotating cleaning nozzles 3, 4, 7 and the fixed cleaning nozzles 5 when the cleaning pump 11 is in operation, and the cleaning agent and leftovers etc. attached to the object to be cleaned 10 are washed away. Perform the rinse step. After the rinsing operation for a specified period of time, the cleaning water containing the cleaning agent and leftovers washed out during the rinsing process is discharged from the drain pump 18 to the outside of the machine, and new cleaning water is added to the cleaning tank 2 to perform rinsing again. operate. After such operation is carried out 3 times, the washing water is discharged outside the machine, and the washing step is also finished.

Next comes the drying operation. The outside air is sent into the cleaning tank 2 from a blower not shown in the figure, and the outside air sent in is heated by the heater 14, and the adhesion to the object 10 to be cleaned is promoted by the effects of both blowing and heating. water droplets evaporate. After such a drying step is carried out for a specified time, the drying operation is stopped, and the entire operation process of the dishwashing is also ended.

In the above steps, the control of adding cleaning water to the cleaning tank 2, the driving control of the cleaning pump 11 and the drain pump 18, the power supply control of the heater 14 according to the temperature detection result of the temperature sensor 17, and the drying The driving control of the blower in the steps is performed by a control device (not shown in the figure) provided in the body 1 of the dishwasher.

Fig. 3 shows the state seen from the front side in the cleaning tank 2 after the lower tableware basket 8 and the upper tableware basket 9 are removed, and the fixed cleaning nozzle 5 and the first rotating cleaning nozzle are shown in a very clear manner in Fig. 3 The structure of 7. Wherein, the aqueduct unit 21 that is located on the rear wall surface of the cleaning tank 2 is set in a flat tubular shape, and this aqueduct unit 21 is composed of a vertical part 5a for supplying water to the fixed cleaning nozzle 5, a horizontal part The right side 5b and the left side 6a of the horizontal part for supplying water to the rotary cleaning nozzle 7 are composed of a roughly cross shape. In addition, a partition is provided at the dotted line position in the figure to divide the passage into two. In the aqueduct unit 21 At the lower end, the left channel and the right channel are respectively connected with the water diversion device 15. There is no injection port on the left channel here, but only constitutes the water guide pipe to the rotary cleaning nozzle 7. The right side of the horizontal part 5b and the left side of the horizontal part The left and right height positions of 6a are different, corresponding to the shape of the upper tableware basket 9 with different heights and a drop.

In addition, the water guide pipe 6b of the rotating cleaning nozzle extending forward is connected with the left side 6a of the horizontal part. In addition, the rotary washing nozzle 7 is provided on the front end portion of the above-mentioned rotary washing nozzle water guide pipe 6 b, and is provided near the center portion below the left side portion of the upper tableware basket 9 . In addition, the water guide pipe 6b of the rotary cleaning nozzle is connected to the left side 6a of the horizontal part in a detachable manner. In other words, the rotary cleaning nozzles 7 can be freely assembled and disassembled relative to the water conduit (water conduit unit 21 ) provided on the rear wall of the cleaning tank 2, and the cleaning water can communicate with each other after being connected. After adopting this structure, when intending to load high tableware etc. into the left side part of the lower tableware basket 8, the rotary cleaning nozzle water guide pipe 6b and the rotary cleaning nozzle 7 can also be removed. In this way, it becomes very convenient when a larger object to be cleaned 10 is set in the lower tableware basket 8 .

FIG. 4 shows in detail the connection structure between the left side 6a of the horizontal part of the water pipe unit 21 and the water pipe 6b of the rotary cleaning nozzle. The water guide pipe 6b of the rotary cleaning nozzle is approximately hollow cylindrical, and four claws 60b are provided on the outer peripheral surface of one end thereof at intervals of 90 degrees. On the other hand, four grooves 60a corresponding to the claws 60b are provided on the coupling portion on the left side 6a of the horizontal portion of the water conduit unit 21 . When inserting the claw 60b from the front to the groove 60a and turning it to the right about 15 degrees, the protrusion 60d will slide over the protrusion 60c and be clamped, so that the left side 6a of the horizontal part of the water conduit unit 21 and the rotating cleaning nozzle Water-tight connection is realized between the water guide pipes 6b.

On the right side 5b of the horizontal part of the fixed cleaning nozzle 5, there are a plurality of cleaning water injection ports 20b. Washing water is sprayed upward on the inner surface of the object to be washed 10 in the dish basket 9 . In addition, a washing water injection port 20a is opened above the vertical portion 5a, and this washing water injection port 20a sprays washing water substantially horizontally in a fan shape. In addition, each cleaning water injection port 20b provided on the horizontal portion 5b does not necessarily spray cleaning water upwards, and may also be arranged so that, for example, the cleaning water spray ports near chopsticks and spoons etc. laterally spray cleaning water. Chopsticks, spoons, etc. that are difficult to wash off dirt are sprayed with washing water emphatically.

In addition, when there is no drop in the upper cutlery basket 9, the horizontal part right side 5b and the horizontal part left side 6a of the aqueduct unit 21 need not be provided with different height positions on the left and right.

The upper surface of the first rotating cleaning nozzle 7 is provided with a plurality of cleaning water spray ports for spraying cleaning water from below to the object to be cleaned 10 installed in the left side part of the upper tableware basket 9 . In this way, washing water can be sprayed from directly below the object to be cleaned 10 contained in the left part of the upper tableware basket 9, and even if the shapes and postures of the tableware are different, it can be washed evenly.

In addition, by arranging the fixed cleaning nozzle 5 in a flat cylindrical shape, it can be prevented from protruding from the rear wall surface of the cleaning tank 2 and the space for placing the object 10 to be cleaned can be reduced. In addition, since the cleaning water injection port 20a arranged on the top of the vertical part 5a sprays the cleaning water in a fan shape substantially along the horizontal direction, the cleaning water can be sprayed from above the object to be cleaned 10 installed in the cleaning tank 2, thereby from The upper surface portion of the object to be cleaned 10 which is difficult to be cleaned by the cleaning water sprayed from below (the main part of the sprayed cleaning water) can also be cleaned. Especially in the object to be cleaned 10 with a bottom (such as a teacup 10a shown in FIG. 1 ) and the like, leftovers are easily accumulated inside the bottom. However, by spraying washing water from above, fine leftovers can also be washed away, and the washing water can reach all surfaces. In addition, by forming the water guide pipe 6b of the rotary washing nozzle in a cylindrical shape, it is also possible to prevent water droplets from adhering to the upper surface, thereby improving the drying performance.

The water dividing device 15 is used to selectively supply cleaning water to a plurality of spraying devices. In the case of selectively supplying cleaning water to four spraying devices in this embodiment, the water dividing device 15 can be used as shown in FIG. The simple structure shown.
