Description

  The present invention relates to a dishwasher for cleaning dishes by spraying washing water onto the dishes stored in a washing tank.

  2. Description of the Related Art Conventionally, dishwashers for general households have been used in which washing water is sprayed onto an object to be cleaned such as dishes arranged in a dish basket installed in a washing tank. At this time, the arrangement of the injection unit for injecting the cleaning water is an important element so that the cleaning water is uniformly injected onto the many objects to be cleaned arranged in the tableware basket.

  In particular, when the dishwasher has a rectangular washing tank, etc., and the dish basket is provided in multiple stages so that a large number of objects can be accommodated in the washing tank, The wash water needs to be sprayed evenly. However, the wash water sprayed from below is sufficiently obstructed by the wash object placed in the lower stage for the wash object stored in the upper table. In this case, the washing water does not reach the surface, and the washing ability for the object to be washed contained in the upper stage is lowered. In particular, when mosses and the like are arranged in the lower stage, there is a problem that most of the jets from below are blocked by the shape, and the object to be cleaned accommodated in the upper stage cannot be cleaned.

  In order to solve these problems, there has been known a dishwasher in which a plurality of spraying units are arranged so that cleaning water can be sprayed onto an object to be cleaned from multiple directions in a cleaning tank. However, in order to be able to inject cleaning water from multiple injection units, it is necessary to increase the amount of water supplied to the cleaning tank, which increases the heating time for heating the cleaning water, and increases the operation time and power consumption. This increases the amount of water used, which necessitates an increase in the size of the cleaning pump, leading to an increase in cost and problems such as increased noise and vibration associated with the use of a large amount of cleaning water.

  In addition, if the number of spraying parts is increased unnecessarily, the product becomes larger, and the installation space for a general household dishwasher is limited, for example, between the work top of a kitchen and a hanging cupboard. There is also the problem of losing.

  Thus, a dishwasher has been developed that is configured so that the amount of water supply does not increase even if a plurality of injection units are provided to improve the cleaning performance, and the above-described problems do not occur (see, for example, Patent Document 1). ).

In this type of dishwasher, as shown in FIG. 6, the bottom surface has a rectangular washing tank 102, and a plurality of spraying units are provided below the washing tank 102 on the rotary washing nozzles 103 and 104 and on the side wall of the washing tank 102. A fixed cleaning nozzle 105 is provided. Washing water pressurized by the washing pump 111 is sequentially switched from the water diversion device 115 and supplied to each of the injection units 103 to 105. As described above, the cleaning water is sequentially switched and supplied to each of the injection units 103 to 105, so that the cleaning water is injected to a large number of objects to be cleaned 110 without increasing the amount of water supply.

(Embodiment 1)
1 and 2 show a state in which an object to be cleaned 10 is accommodated in a washing tub 2 of a dishwasher body 1 having a rectangular bottom surface according to Embodiment 1 of the present invention, as viewed from the front side and the side. Thus, in the cleaning tank 2, a lower table basket 8 and an upper table basket 9 for storing the article to be cleaned 10 are arranged so that they can be pulled out in the front-rear direction. The lower table basket 8 has a left side as a space for installing a bowl or the like, and a right side as a space for installing a dish or the like. The upper table basket 9 is arranged in a position that is one step lower than the right side, and the left side has a high space so that various dishes such as dishes and cups can be placed. Since there is no space height on the right side of the car 9, a space for placing cylindrical dishes such as a short cup and a cup of tea is provided.

  A first rotary cleaning nozzle 3 and a second rotary cleaning nozzle 4 are disposed below the cleaning tank 2, and a fixed cleaning for cleaning the right side of the upper table basket 9 on the back of the cleaning tank 2. A nozzle 5 is provided. Further, the water conduit unit 21 is configured with the fixed cleaning nozzle 5, the right cleaning route is configured as the fixed cleaning nozzle 5, and the left channel is configured as a water conduit for the third rotary cleaning nozzle 7 for cleaning the left side of the upper car. As a configuration of the water conduit of the third rotary cleaning nozzle 7, a rotary nozzle water conduit 6b extending forward is connected to the horizontal portion left side 6a of the water conduit unit 21, and further, the tip of the rotary nozzle water conduit 6b. In addition, the third rotary cleaning nozzle 7 is disposed at a position below the left side of the upper table basket 9.

Cleaning water is sprayed from the first rotary cleaning nozzle 3, the second rotary cleaning nozzle 4, the fixed cleaning nozzle 5, and the third rotary cleaning nozzle 7 to the object to be cleaned 10 accommodated in the cleaning tank 2. Thus, the article to be cleaned 10 is cleaned.

  A drainage port 12 communicating with the suction side of the cleaning pump 11 is provided at the bottom of the cleaning tank 2, and a drainage filter 13 for collecting leftovers and a heater 14 for heating the cleaning water are arranged in the drainage port 12. It is installed. The washing water that has passed through the leftover filter 13 is sucked into the washing pump 11 and pressurized, and is supplied from the first, second, and third rotary washing nozzles 3, 4, 7 and the fixed washing nozzle 5 by the water diverting means 15. Wash water is jetted.

  In the dishwasher 1 having the above-described configuration, the lower table basket 8 and the upper table basket 9 in which the door 16 is opened and the object 10 to be cleaned are accommodated are accommodated in the washing tub 2, and the detergent is added to the washing tub 2 by the door 16. When the front opening is closed, the operation is started, and the cleaning process, the rinsing process, and the drying process are executed in this order.

  First, the water supply valve is operated to supply a predetermined amount of cleaning water into the cleaning tank 2. The supplied cleaning water is heated by the heater 14, pressurized by the cleaning pump 11, and selected from the water diverting means 15 to the first, second and third rotary cleaning nozzles 3, 4, 7 and the fixed cleaning nozzle 5. Washing water is sent. Here, the water distribution means 15 switches the supply of cleaning water at predetermined intervals in the order of the first rotary cleaning nozzle 3, the second rotary cleaning nozzle 4, the fixed cleaning nozzle 5, and the third rotary cleaning nozzle 7. To work. The first, second, and third rotary cleaning nozzles 3, 4, and 7 are rotated by a jet flow in which the supplied cleaning water is ejected from the injection port, and the rotating cleaning water is jetted to inject the lower dish basket 8 and the upper stage. The to-be-cleaned object 10 accommodated in the tableware basket 9 is washed. The fixed cleaning nozzle 5 sprays cleaning water mainly from the injection holes arranged horizontally below the upper tableware basket 9 to the right side of the upper tableware basket 9 to accommodate the inner surface of the object to be cleaned 10 stored downward. In addition, the outer surface of the object to be cleaned 10 is cleaned with the cleaning water sprayed in a fan shape in a substantially horizontal direction from the cleaning water injection port 20a opened at the top.

  When the arrangement of the objects to be cleaned 10 on the lower tableware basket 8 is set to the left side such as bowls, and the right side is set to dishes and the like, the capacity of the objects to be cleaned 10 in the upper tableware basket 9 is taken into consideration. Since the installation height of bowls and the like is relatively low compared to dishes and the like, the left side of the upper table basket 9 is set to a position one level lower than the right side. Considering the case where the object to be cleaned 10 accommodated in the upper tableware basket 9 is cleaned using only the fixed nozzle provided on the back of the cleaning tank 2, the left side of the upper tableware basket 9 is set at a low position. Therefore, it is not possible to obtain a spray angle sufficient to clean the object to be cleaned from the fixed nozzle provided on the back surface of the cleaning tank 2. In addition, the supply of washing water from below cannot be expected due to obstacles such as moss arranged below. Furthermore, since the left side has a high space height, it is a space where various shapes of objects to be cleaned 10 can be placed, and the fixed nozzle can inject cleaning water only at a fixed angle within a certain range. Cannot handle various shapes and installation postures.

  Therefore, in order to ensure the cleaning performance of the article to be cleaned 10 accommodated in the upper tableware basket 9, it is necessary to provide the third rotating nozzle 7 below the left side of the upper tableware basket 9.

  On the other hand, when the height of the dishwasher main body 1 is fixed in order to secure the installation property of the dishwasher main body 1, there is a relatively high installation dish or the like on the right side of the upper table basket 9. Since it is installed, there is not enough space to arrange the rotating nozzle, but since the object 10 to be cleaned in the upper table basket 9 is stored at a high position, a sufficient injection angle is set from the fixed nozzle 5 provided on the back surface of the cleaning tank 2. In addition, the supply of washing water from below can be obtained from the shape of the dishes. Furthermore, it is a space for installing cylindrical tableware such as a short cup or a cup of water, and since the installation posture and tableware shape are determined to some extent, the cleaning performance can be ensured even if the fixed nozzle 5 is used.

  Moreover, about the installation property of the to-be-cleaned object 10 by adding the 3rd rotation washing nozzle 7, it extends in the front-back direction by extending the rotation washing nozzle conduit 6 from the rear toward the front toward the center of the washing tank 2. By having the water conduit to the, the installation property of the object to be cleaned 10 is ensured without interfering with the object 10 to be cleaned.

  The cleaning water sprayed from the first, second and third rotary cleaning nozzles 3, 4, 7 and the fixed cleaning nozzle 5 in the cleaning tank 2 cleans the object to be cleaned 10 and flows down to the lower part of the cleaning tank 2. The first, second and third rotary cleaning nozzles 3 are collected at the drainage port 12 and heated again by the heater 14, pass through the leftover filter 13, and again from the cleaning pump 11 through the water distribution means 15. 4 and 7 are fed to the fixed cleaning nozzle 5. The leftovers dropped from the object to be cleaned 10 after the washing water is jetted are collected in the leftover filter 13. Further, the temperature of the cleaning water is detected by the temperature sensor 17, and when the temperature exceeds a predetermined temperature, the energization to the heater 14 is stopped, so that a temperature suitable for cleaning is maintained.

  When the cleaning process for a predetermined time is completed, the cleaning water containing dirt is discharged from the drain pump 18 to the outside of the apparatus, and the cleaning water is newly supplied into the cleaning tank 2. The supplied cleaning water is sprayed from the first, second and third rotary cleaning nozzles 3, 4, 7 and the fixed cleaning nozzle 5 by the operation of the cleaning pump 11, and the detergent and leftovers attached to the object to be cleaned 10. A rinsing step for flushing is performed. In this rinsing process, after a predetermined time of operation, the washing water from which the detergent and the remaining vegetables have been washed out by rinsing is discharged from the drainage pump 18 to the outside of the machine, and new washing water is supplied into the washing tank 2 and rinsed again. The process of performing the operation is executed three times, and the rinsing process is completed by discharging the wash water out of the machine.

  Subsequently, a drying process is executed, and the outside air fed into the cleaning tank 2 from a blower (not shown) is heated by the heater 14, and evaporation of water droplets adhering to the object to be cleaned 10 by both effects of blowing and heating is performed. Promoted. After this drying process is carried out for a predetermined time, the operation is stopped and all the steps of washing the dishes are completed.

  Feeding control of washing water into the washing tank 2 in each of the above processes, driving control of the washing pump 11 and the drainage pump 18, energization control to the heater 14 based on temperature detection by the temperature sensor 17, driving control of the blower in the drying process, etc. Is implemented by a control device (not shown) provided in the dishwasher body 1.

  FIG. 3 shows a state in which the lower table basket 8 and the upper table basket 9 are taken out from the inside of the cleaning tank 2 as viewed from the front side. The forms of the fixed cleaning nozzle 5 and the third rotary cleaning nozzle 7 Is clearly shown. The water conduit unit 21 disposed on the back surface of the cleaning tank 2 is formed in a flat cylindrical shape, and a vertical portion 5 a for the fixed cleaning nozzle 5, a right side portion 5 b for the fixed cleaning nozzle 5, and a horizontal portion left side 6 a for the third rotary cleaning nozzle 7. Is formed in a substantially cross shape. In addition, a partition is provided at a position indicated by a broken line in the drawing, and the route is divided into two. At the lower end of the water conduit unit 21, the left route and the right route are separately connected to the water distribution means 15. Here, the left-side path is configured as a water conduit for the third rotary cleaning nozzle 7 without an injection port. The horizontal part right side 5b and the horizontal part left side 6a have different height positions on the left and right, corresponding to the fact that the upper table basket 9 is formed in a shape having steps with different heights on the left and right.

Further, a rotary washing nozzle conduit 6b extending forward is connected to the left side 6a of the horizontal portion, and further, at the tip of the rotary washing nozzle conduit 6b, near the lower center of the left side of the upper tableware basket 9. 3 rotary cleaning nozzles 7 are arranged. Further, the rotary cleaning nozzle conduit 6b is detachably connected to the horizontal portion left side 6a, and in the case of storing high tableware or the like on the left side of the lower table basket 8, the rotary cleaning nozzle conduit 6b and the third By removing the rotary cleaning nozzle 7, it is possible to improve the installation property of the large object 10 to be cleaned in the lower table basket 8. FIG. 4 shows in detail the connection configuration between the horizontal portion left side 6a of the water conduit unit 21 and the rotary cleaning nozzle water conduit 6b. The rotating nozzle water conduit 6b has a substantially hollow cylindrical shape, and four claw portions 60b are provided on the outer periphery of one end portion every 90 degrees, while the connection portion of the horizontal portion left side 6a of the water conduit unit 21 is provided. Four groove portions 60a corresponding to the claw portions 60b are disposed. After inserting the claw portion 60b and the groove portion 60a with the hole positions aligned from the front, the claw portion 60b and the groove portion 60a are rotated to the right by about 15 degrees and locked by the protrusion 60d getting over the protrusion 60c, and fixed to the rotary cleaning nozzle conduit 6 and fixed cleaning. The nozzle 5 is connected in a watertight manner.

  On the right side 5b of the horizontal portion of the fixed nozzle 5, a plurality of cleaning water injection ports 20b for injecting cleaning water to the object to be cleaned 10 accommodated in the upper tableware basket 9 are opened, and the object to be cleaned accommodated in the upper tableware basket 9 is opened. Washing water is jetted upward toward the inner surface of the object 10. Further, a cleaning water injection port 20a is opened above the vertical portion 5a, and the cleaning water is injected in a fan shape in a substantially horizontal direction. In addition, each of the plurality of cleaning water injection ports 20b provided in the horizontal portion 5b does not necessarily inject the cleaning water upward. For example, the cleaning water outlet near the accommodation place such as chopsticks and a spoon is cleaned sideways. The cleaning water may be sprayed mainly on chopsticks or spoons that are difficult to remove by spraying water. Further, the horizontal part right side 5b and the horizontal part left side 6a of the water conduit unit 21 do not need to be formed in shapes having different height positions on the left and right when the upper table basket 9 has no step.

  The upper surface of the third rotary cleaning nozzle 7 has a plurality of cleaning water injection ports for injecting cleaning water from below into the object stored in the left side of the upper table basket 9 and accommodated in the left side of the upper table basket 9 Cleaning water can be sprayed onto the object to be cleaned 10 from directly below, and even various tableware shapes and installation postures can be cleaned evenly.

  By forming the fixed nozzle 5 in a flat cylindrical shape, the fixed nozzle 5 does not protrude from the back surface of the cleaning tank 2 and does not reduce the storage space for the object to be cleaned. Moreover, since the washing water injection port 20a provided in the upper part of the vertical part 5a injects the washing water in a substantially horizontal fan shape, the washing water can be applied from above the article to be washed contained in the washing tank 2. It is possible to clean the upper surface portion of the object to be cleaned 10 which is difficult to be cleaned with the cleaning water sprayed from below, which is the main body of the cleaning water injection. In particular, an object to be cleaned 10 having a thread bottom, for example, a tableware having a thread bottom such as a cup 10a shown in FIG. 1, is likely to leave fine leftovers in the thread bottom. Fine leftovers are washed out, and the effect of spreading wash water on all surfaces is obtained. Moreover, the rotating nozzle water conduit 6 is made into a cylindrical shape, thereby eliminating the adhesion of water droplets to the upper surface and improving the drying performance.

  In the case of selectively supplying cleaning water to four injection units as in the configuration of the present embodiment, the water distribution means 15 that selectively supplies cleaning water to a plurality of injection units is shown in FIG. The water dividing means 15 can be configured in such a simple structure.

  FIG. 5 schematically shows an example of the configuration of the water distribution means 15. One water supply opening is provided on the peripheral surface of a cylindrical water distribution valve 40 to which the cleaning water is supplied from the cleaning pump 11 at the center. Portion 41 opens, water supply pipe 42 piped to the fixed cleaning nozzle in the clockwise 45 degree direction with 0 degree above the paper surface, water supply pipes 43 and 225 piped to the second rotary cleaning nozzle 4 in the 135 degree direction The water supply pipe 44 piped to the first rotary cleaning nozzle 3 in the direction of the angle and the water supply pipe 45 piped to the third rotary cleaning nozzle 7 in the direction of the 315 degree are arranged to face the peripheral surface of the water diversion valve 40, respectively. Has been.

When the water diversion valve 40 is rotated every 90 degrees by a driving means (not shown) and rotated to the angular position shown in FIG. 5A, the water supply opening 41 opens in the direction of the water supply pipe 44. The cleaning water supplied from the cleaning pump 11 into the diversion valve 40 is supplied to the first rotary cleaning nozzle 3. 5B, the water supply opening 41 opens in the direction of the water supply pipe 43, so that the cleaning water supplied from the cleaning pump 11 into the diversion valve 40 is the second. To the rotary cleaning nozzle 4. 5C, the water supply opening 41 opens in the direction of the water supply pipe 42, so that the cleaning water is supplied to the fixed cleaning nozzle 5. When the water diversion valve 40 is rotated to the angular position shown in FIG. 5 (d), the water supply opening 41 opens in the direction of the water supply pipe 45, so that cleaning water is supplied to the third rotary cleaning nozzle 7. Is done.

  By configuring the water dividing means 15 as in the above configuration example, the cleaning water is supplied only to the first rotary cleaning nozzle 3 described above, and the cleaning water is supplied only to the second rotary cleaning nozzle 4. It is possible to sequentially switch to a state where cleaning water is supplied only to the fixed cleaning nozzle 5 and a state where cleaning water is supplied only to the third rotary cleaning nozzle.

  By supplying the cleaning water selectively to the plurality of jetting units in this way, the amount of water supplied in the cleaning tank 2 is increased when the cleaning water is supplied to all of the plurality of jetting units at the same time. Problems such as an increase in power consumption and an increase in size due to an increase in the amount of water used and an increase in temperature rise time can be solved.

  As described above, the dishwasher according to the present invention can obtain high cleaning performance and washability by effectively combining the rotary cleaning nozzle and the fixed cleaning nozzle. Therefore, it is useful as a dishwasher for cleaning an object to be cleaned.
