Description

  The present invention relates to a dishwasher that increases the number of dishes.

  In general, it is required that the dish basket provided in the dishwasher can support and arrange as much as possible the dishes to be washed on condition that the dishwasher can be reliably washed. In particular, in a compact type in which a dishwasher is installed on a kitchen sink and used, it is strongly desired that a large number of dishes can be set efficiently while being limited in space. In this background, for example, it is assumed that it can be used by a family of six, and as standard tableware, there are usually combinations of large, medium and small plates, tea bowls, soup bowls, hot water and cups, small bowls, etc. It is considered that cooking utensils such as kitchen knives and pans can be washed as well as small items such as kitchen utensils and spoons. Among them, except for tea bowls and soup bowls, individuals use multiple, and considering the dishes and takeout dishes used for common use, how many dishes can be set in the recent trend toward compactness? One of the important issues.

Therefore, conventionally, for example, a rotatable shelf is provided above one side of the tableware basket, and if necessary, the shelf is expanded to place cups, cups, etc. so that more tableware can be washed (for example, Patent Document 1).
JP 2001-231737 A (4th and 5th pages, FIG. 1)

  However, in the thing of the said patent document 1, in the magnitude | size and shape of shelf itself, the structure which rotates, and space restrictions are received, The number of tableware points which can be accommodated in the tableware basket which is a washing capacity | capacitance which can be washed at once. Is not enough. Therefore, as a countermeasure, for example, it is conceivable to arrange tableware baskets having approximately the same capacity in two upper and lower stages in the cleaning tank. According to this, an increase in the number of dishes can be expected, but in a limited space in the washing tank, it is a big problem whether the original washing performance can be maintained especially for the dishes set in the upper stage. come.

  In order to solve the above-mentioned problems, the present invention provides a dishwasher in which a tableware basket is arranged in two upper and lower stages, and more dishes can be set and desired cleaning performance can be secured. The purpose is to do.

  In order to achieve the above object, the dishwasher according to the present invention accommodates a tableware basket in which tableware is set in a washing tub in two upper and lower stages so that it can be put in and out as an upper basket and a lower basket, respectively. The main feature of the present invention is that a tableware support portion is provided between the upper basket and the lower basket, which can set other tableware in the space over the shoulder of the tableware set in the lower basket.

  According to the tableware washing machine of the present invention, since a large number of tableware can be stored in the upper and lower two stages, and the tableware support unit capable of setting other tableware using the over-the-shoulder space is provided, the cleaning performance is improved. It is possible to provide a dishwasher that is convenient for practical use because it is possible to set a larger number of tableware while maintaining the reduction and compact configuration.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a side view showing a cut-out of important points, FIG. 2 is a front view showing a state in which a door 3 to be described later is removed, and FIG. 3 is a view corresponding to FIG. The overall configuration of the dishwasher will be described. Reference numeral 1 denotes a dishwasher main body, which includes an outer box 2 constituting an outer shell thereof and a door 3 provided on the front surface thereof, a cleaning tank 4 inside, and a cleaning mechanism section 5 and the like below. The configuration is as follows.

  The cleaning tank 4 contains an upper basket 6 and a lower basket 7 that are individually arranged in two upper and lower stages as a tableware basket, as will be described in detail later. As shown, an operation panel 8 is provided, and includes various operation keys 8a for setting the operation course of the dishwasher, starting and stopping the operation, and the like. A control device 11 composed of a microcomputer or the like is provided on the back side of the operation panel 8, which controls the overall operation of the dishwasher based on operation input by the operation panel 8.

  More specifically, the door 3 is composed of a lower door 3a that rotates with a lower end portion as a fulcrum and an upper door 3b that rotates with an upper end portion as a fulcrum, and the lower door 3a includes a door (not shown). The lock release button 9 and the handle 10 are provided in conjunction with the lock mechanism. Accordingly, when the door 3 is opened, if the handle 10 is pulled forward while pressing the unlock button 9, the lower door 3a is pivoted downward and the upper door 3b is pivoted upward in conjunction therewith. Thus, the front opening of the washing tub 4 which is the front surface of the main body 1 can be greatly opened, so that the tableware basket can be easily put in and out.

  Further, the cleaning tank 4 occupying a large space in the outer box 2 has its front opening closed in a watertight manner by the door 3 described above, and the cleaning mechanism 5 described above is disposed at the bottom thereof. The cleaning mechanism unit 5 includes a cleaning pump 12, a pump motor 13 that drives the cleaning pump 12, and an injection body 15 that will be described later. A drainage pump 14 that is arranged coaxially with the cleaning pump 12 is also included in the pump motor. 13 is driven in common. As a drive control means for that purpose, a motor capable of forward / reverse rotation is used as the pump motor 13. For example, the cleaning pump 13 normally functions as a pump during forward rotation in the clockwise direction, while the drainage pump 14 does not function effectively. In some cases, the drain pump 14 can function normally and drain outside the machine, but the washing pump 12 has a pump runner shape or a clutch mechanism so as not to function effectively.

  As described above, the rotatable sprayer 15 is supported in communication with the inner bottom portion of the cleaning tank 4 via the shaft tube portion 16 with respect to the cleaning pump 12 at the outer bottom portion of the cleaning tank 4, and the shaft tube portion 16 is The cleaning pump 12 is connected to the discharge side of the cleaning pump 12 and thus functions as the cleaning mechanism unit 5. The suction side of the cleaning pump 12 is connected to the recess 4a, which is the lowest part of the cleaning tank 4, via the connecting pipe 17, so that, for example, the cleaning mechanism 5 is driven during the cleaning operation. The cleaning water supplied into 4 is pumped from the recess 4 a to the spray body 15 via the cleaning pump 12 and is sprayed upward from the spray body 15 in the cleaning tank 4. Repeat the water cycle. In this case, the ejector 15 is rotated in one direction by utilizing the reaction when the wash water is ejected obliquely in the lateral direction.

Although not described in detail, the inner bottom of the cleaning tank 4 is provided with a heater 18 for heating and warming the outside air taken in during the heating or drying operation of the cleaning water, and a blower for blowing air on the outer wall. 19, a water supply valve 20 for water supply and a float type water level switch 21 for detecting a predetermined water level, for example, are provided in communication with the cleaning tank 4.
Next, the upper basket 6 and the lower basket 7 that are arranged in the upper and lower stages in the washing tub 4 as a tableware basket will be described in detail. These are formed into a rectangular frame shape by assembling wires, and the door as described above. 3 is opened and removed from the front, and both are supported so as to be slidable in the front-rear direction. As the slide support means, the support means for the upper car 6 will be described with reference to FIG. 2. Rail members 22 extending in the front-rear direction are fixedly provided on the left and right side walls of the cleaning tank 4.

  On the other hand, the upper cage 6 is provided with slide members 23 on both right and left sides, and a plurality of, for example, three stages of groove portions 23a, 23b, and 23c are formed on the outer surface of the slide member 23. The rail member 22 is slidably engaged with each of the groove portions 23a to 23c. Accordingly, by selecting any one of these groove portions 23a to 23c and slidably engaging with the rail member 22, the accommodation position of the upper car 6 can be adjusted in three stages.

  Incidentally, in the embodiment shown in FIG. 2, the rail member 22 is engaged with the uppermost groove 23a, and the upper cage 6 is housed in the lowest position. In this case, the space between the upper basket 6 and the ceiling surface of the washing tub 4 is large, which is convenient for setting tall dishes and the like. On the other hand, when the lowermost groove 23c is engaged with the rail member 22, the upper car 6 is accommodated and supported at the highest position, and the lower car space described later is made taller by increasing the space space below. Convenient for setting tableware.

Note that the upper car 6 shown in the present embodiment has a stepped structure in which the left half is in the deep bottom form and the right half is in the shallow bottom form, and this is in combination with the upper car 6 being accommodated in the lowest position. Thus, for example, a large pot 24 can be set on the deep bottom side as tableware, and a plurality of cups 25 can be set on the shallow bottom side.
In contrast to the upper car 6, the lower car 7 is held at a predetermined height which is slightly above the ejector 15 in a state of being housed in the cleaning tank 4, and is formed in a shallow frame shape as a whole. It is supported so as to be slidable in the front-rear direction. As for the slide support means, rail members 26 are fixedly provided on the left and right side walls of the lower portion of the cleaning tank 4, while slide members 27 are attached to both lower portions of the lower car 7, and the slide members 27 are the rail members. The lower car 7 is supported so as to be slidable in the front-rear direction.

  In such a lower basket 7, in particular, as shown in FIG. 2, a plurality of tea bowls 28a and soup bowls 28b (see FIG. 4 to be described later) are arranged in two rows (see FIG. 1) in the lateral direction. Set up side by side, a cylindrical accessory case 31 containing a long spoon 29, chopsticks 30 and the like is erected and held in the right half, and a plurality of dishes 32 are arranged in a row in the center position (see FIG. 3). Set side by side. Among the plates 32, in FIG. 2, a large plate 32a having a large diameter and a medium plate 32b having a slightly large diameter are arranged and set upright.

  As the setting means for easily supporting the tableware in such a tableware basket, the upper basket 6 has a structure in which the pot 24 and the cup 25 are placed and supported on the bottom, and the lower basket 7 On the left side, a relatively short tableware support 33 standing upside down (see FIG. 1) from the bottom is arranged in two rows, and each tableware support 33 is as shown in FIG. The first and second supports 33a and 33b, which are long and short, are configured as a pair. Therefore, the arrangement is supported and set so that the individual tea bowl 28a and the soup bowl 28b are sandwiched between the supports 33a and 33b.

  On the right side, a plurality of long table supports 34 erected in an inverted C shape from the bottom are arranged in a horizontal row, and the dishes 32 are held and set between the table supports 34 in a standing state. ing. In this case, as will be apparent from FIG. 2, in the present embodiment, the upper cage 6 has a stepped bottom structure, and for example, the right side has an upper shallow bottom configuration, so that a large lower space can be secured. This means that on the right side of the lower basket 7 corresponding to the space, a large-sized dish 32, a long spoon 29, and a barley tea teapot, a ladle or chopsticks (not shown) can be set with a margin.

  Thus, although the lower basket 7 having the above configuration has the convenience of being able to efficiently set a wide variety of tableware by combining with the upper basket 6 having a different configuration, the number of tableware is increased. Not necessarily clear. Therefore, in the present embodiment, the lower basket 7 is further provided with a tableware support portion 35, and in particular, a setting means suitable for holding a small plate 36 having a thin shape and a small diameter, for example, a diameter of about 12 cm is provided. Yes. Hereinafter, a specific configuration of the tableware support portion 35 will be described with reference to a plan view showing a main portion of the lower basket 7 of FIG.

  First, as shown in the plan view of FIG. 4, the tableware support portion 35 is disposed in a space area on the left side of the lower basket 7, and has a short length at an intermediate position where the tableware supports 33 are arranged in two rows. A plurality of tableware supports 37 are arranged in a horizontal row. At this intermediate position, the brown basket 28a and the soup bowl 28b are set in two rows on the lower basket 7, and a gap S is secured between them. This gap S is mainly formed so that the water jetted from the jetting body 15 below the lower basket 7 can easily escape upward, and the dishes set in the upper basket 6 can be washed effectively. Yes.

  Thus, the table support 37 is arranged by effectively using the gap S. The size of the gap S is not large enough to arrange the small plate 36 as tableware. Therefore, the tableware support 37 is specifically disposed in the upper space A indicated by a two-dot chain line above the gap S as shown in FIG. Although details of the upper space A will be described later, this is formed above the tea bowl 28a and the soup bowl 28b, which are set on the left side of the lower basket 7, and formed between the bottom of the upper basket 6 and the upper basket 6. Pointing to the designated space.

  Next, the specific structure of the tableware support 35 will be described. As shown in FIGS. 1 and 2, two wires are provided upright in parallel from the bottom of the lower basket 7 using a gap S, and have a predetermined height. It has a bridge-shaped support leg portion 38 which is slightly expanded in the horizontal position and is in a horizontal state, and a long first tableware support 37a and a short second support 37b which are erected almost directly on the horizontal portion. A plurality of tableware supports 37 are provided in a horizontal row. With this, the small plate 36 can be set upright so as to be clamped by the tableware support 37, but the tableware support 37 has a sufficient interval so that there is a gap between the small plates 36. It is arranged so that it can be placed and set.

  However, when the upper space A where the tableware support 37 is located is described, this is roughly between the upper basket 6 and the lower bowl 7 serving as the tea bowl 28a and the soup bowl 28b as described with reference to FIG. Specifically, the upper limit is a horizontal, substantially flat surface shape at the bottom of the upper car 6, whereas the lower limit is an uneven shape along the outer shape of the tableware. . In the background of the upper space A, the wash water sprayed from below is higher when the upper basket 6 faces the tableware set in the lower basket 7 through some space. Based on the fact that it is effective for spraying evenly on tableware, and the tableware of the lower basket 7 is generally overwhelmingly circular, there is a small space recessed over the shoulder of these tableware. There are circumstances that are always formed.

  For example, in the configuration of the lower basket 7 suitable for setting the tea bowl 28a and the soup bowl 28b as in this embodiment, in addition to some space in the vertical direction as shown in FIG. So-called over-the-shoulder spaces A1, A2, A3, and A4 are mainly formed of a plurality of small spaces formed over the shoulders. The aggregate of the over-shoulder spaces A1 to A4 forms the upper space A.

Incidentally, in this embodiment, the tableware support 37 on which the small plate 36 is set uses the widest area corresponding to the gap S between the two shoulder spaces A2 and A3 and other rows of tableware. It is possible to support the arrangement so as not to overlap as much as possible.
Such over-the-shoulder spaces A1 to A4 are not formed only on the left side of the lower car 7. For example, when the right platters 32a are arranged in a row as shown in FIG. The two shoulder spaces B1 and B2 are formed. However, in the case of the platter 32a, the over-shoulder spaces B1 and B2 are divided at the substantially central portion by the platter 32a. Spaces are also added to form continuous shoulder spaces B1 and B2. However, in any case, the vertical space in the over-the-shoulder spaces B1 and B2 does not cause any particular difference regardless of whether it is continuous or discontinuous. 6, it can be said that another upper space B formed for the same purpose as the upper space A is formed.

Next, the operation of the dishwasher having the above configuration will be described.
First, FIG. 1 to FIG. 3 show a state in which predetermined utensils are set in the lower baskets 6 and 7 after being arranged in the upper and lower stages in the washing tank 4, and the operation starts in this state. By doing so, a washing process, a rinsing process, a drying process, and the like are automatically executed in response to a program stored in the control device 11 and an input signal from the water level switch 21 and the like, as is well known.

  In the washing process, the cleaning action of the tableware set in the lower basket 7 provided with the tableware support portion 35 will be described. As the washing operation in this washing process is normally performed, the washing water driven by the washing mechanism unit 5 and pumped from the washing pump 12 is vigorously jetted mainly obliquely upward from the jetting body 15, and The injection body 15 rotates by the injection reaction, and the cleaning water is uniformly injected upward. As a result, not only the dishes normally set in the lower basket 7 immediately above (small items such as tea bowl 28a, soup bowl 28b, dish 32, spoon 29 etc. in the embodiment), but also the washing water that has escaped upward between these dishes. Then, the dishes such as the pot 24 and the cup 25 set in the upper basket 6 are washed.

  However, the tableware set in the tableware support portion 35 attached to the lower basket 7, that is, the so-called small bowl 36 in the embodiment is arranged by effectively utilizing the upper space A between the upper basket 6 and Can be set without overlapping with other adjacent tableware. Specifically, the small plate 36 is located in the middle of the two rows of the tea bowl 28a and the soup bowl 28b, and is located in the upper space A corresponding to the gap S between the dishes, and the shoulder over the shoulder that is the widest area. Arrays are supported in the spaces A2 and A3. Therefore, the spray washing water that has passed through the gap S is easy to escape upward, and can effectively wash the small plate 36 set on the tableware support portion 35, and each small plate 36 is supported by the tableware support 37 at intervals. Therefore, the washing water that has passed through the gap S functions effectively for dish washing on the upper basket 6 side.

  The tableware set in the tableware basket can be taken out by pulling out the upper basket 6 and the lower basket 7 to the required positions, respectively, and in the lower basket 7, a tableware support portion 35 is provided in the middle horizontal row. Therefore, when the rear side soup 28b is put in and out, the lower basket 7 is easily pulled out from the large front opening by pulling out the lower basket 7 appropriately onto the lower door 3a opened from the front opening of the cleaning tank 4 to the horizontal position. Can be operated. In addition, it goes without saying that various kinds of tableware such as different heights can be efficiently set in the upper and lower baskets 6 and 7 in combination with the stepped configuration of the upper basket 6 and can be effectively washed.

As described above, the present embodiment has the following effects.
A table basket is composed of an upper basket 6 and a lower basket 7 that are arranged in two upper and lower stages, so that a large number of tableware can be washed and formed between the upper basket 6 and the upper basket 6. By utilizing the upper space A, a tableware support portion 35 on which another small-sized tableware (small plate 36) can be additionally set is provided. As a result, it can arrange | position without superposing | polymerizing as much as possible with other adjacent tableware, and can aim at the increase in the number of tableware while being able to wash | clean effectively. In addition, the upper space A is a space over the shoulder formed over the shoulder of the tableware because the tableware (tea bowl 28a, soup bowl 28b) set in the lower basket 7 is generally circular. It can be constructed from an assembly of A1 to A4, and is advantageous in that it can be formed and used effectively without increasing the size of the cleaning tank 4 or the main body 1.

  In particular, as shown in the present embodiment, the tableware support portion 35 is located in the middle position of the tableware (tea bowl 28a, soup bowl 28b) arranged in two rows in the lower basket 7 of the upper space A, Since it is arranged in two consecutive shoulder spaces A2 and A3 above the gap S, tableware can be set in a wide area, and the largest tableware, for example, about 12 cm in diameter, in the restricted tank space A small plate 36 can be set. In addition, since it is arranged and supported at intervals in a horizontal row, the flow of the jet cleaning water is good and the dishes in the upper upper basket 6 can be cleaned effectively.

  In the present embodiment, the upper space A is described as being formed above the relatively small bowl 28a or the like set on the left side of the lower basket 7. However, other spaces can be formed. For example, as described above, the upper space A is mainly composed of the space formed over the shoulder of the set tableware, and therefore, in this embodiment, as shown in FIG. The over-shoulder spaces B1 and B2 are also formed over the shoulder of the tall tableware (dish 32), and an upper space B having the same meaning is formed although the so-called form is different. Accordingly, the over-the-shoulder spaces B1 and B2 are portions corresponding to the above-mentioned over-the-shoulder spaces A1 and A4, which are slightly smaller than the continuous over-the-shoulder spaces A2 and A3 in the middle portion. It is possible to provide a tableware support portion for supporting tableware having a diameter of about 10 cm or less, such as a small very small plate, for example, a hand salt plate.

  In addition, since the upper basket 6 in this embodiment employs slide means that can be adjusted in height in addition to the stepped structure, the upper basket 6 may be accommodated and arranged at the upper position depending on the tableware set in the upper basket 6. It is also possible to use the upper space A or B with the car 7 in a larger area, which can improve the cleaning performance in a spare space, or can be used for dishes having a diameter larger than the small plate 36 described above. For example, it is possible to perform cleaning.

(Second Embodiment)
On the other hand, FIG. 5 shows a second embodiment of the present invention. In the following, the same parts as those in the above-mentioned embodiment are denoted by the same reference numerals and the description thereof will be omitted, and only different parts will be described.
This is different from the above-described embodiment only in the configuration of the lower car 38 disposed in the lower stage, and the other is common. More specifically, in the configuration of the tableware support portion 39 of the lower car 38, Only different. 5A is a perspective view showing a main part of the lower car 38, and FIG. 5B is a perspective view showing a state in which tableware is set.

  5A. On the left side, which is the main part of the lower car 38 shown in FIG. 5A, a plurality of short table supports 40 standing upside down from the bottom are arranged in two rows. The support 40 is composed of a pair of first and second supports 40a and 40b which are long and short. Therefore, as shown in FIG. 5 (b), between each of these supports 40a, 40b is arranged and supported in two rows so that the individual tea bowl 28a and soup 28b are sandwiched between them. Such a configuration, such as having a gap S, is substantially the same as the above embodiment.

  However, in the present embodiment, the tableware support portion 39 for setting the small plate 36 is characterized by the following configuration different from the above embodiment. That is, the tableware support portion 39 is formed by bending two parallel wires in the center portion forming the bottom portion of the lower basket 38 from the position where it reaches the left edge of the lower cage 38 and standing substantially vertically. From the combination of the raised first support 41a and the second support 41b having a hook shape so as to face the two extended end portions thereof at a predetermined height position (the region of the upper space A). Thus, the first and second supports 41a and 41b serve as a tableware support for supporting one tableware.

  As can be understood from the above-described configuration, the tableware support portion 39 is erected on the leftmost edge of the lower basket 7 at an intermediate position of the tableware (tea bowl 28a and soup bowl 28b) arranged in two rows. Accordingly, as shown in the figure, the tableware support 39 supports one small plate 36 described above. In other words, it can be said that in this embodiment, the number of dishes corresponding to the normal lower basket 38 is increased by one tableware. In this case, because of the configuration in which one tableware is arranged at the edge, it is possible to set tableware having a diameter larger than that of the small plate 36 described above.

  Thus, according to the present embodiment, for example, one point of the small plate 36 can be additionally set on the tableware support part 39, but the convenience is high. That is, it can be set without particularly hindering the taking in and out of tableware (tea bowl 28a, soup bowl 28b) set on the bottom of the lower basket 38, and the workability is good. The attaching / detaching operation can be easily performed, for example, without the trouble of pulling out the lower basket 38 out of the cleaning tank 4 each time it is set. Moreover, since the tableware support portion 39 is located at the edge at the intermediate position, it is arranged with sufficient space in the upper space A, and thus is effective without interfering with other tableware. The cleaning water sprayed from the gap S at the intermediate position can contribute to the cleaning of the upper tableware with almost no trouble, so that the high cleaning performance for the entire tableware can be maintained.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings. For example, a plurality of spray bodies as cleaning means may be installed to eliminate the blind spot of the spray cleaning water, or If, for example, a fixed spray body mainly composed of a basket is installed, further improvement in cleaning performance can be expected, and a necessary and sufficient cleaning effect can be expected even if the number of dishes increases slightly.
In addition, the tableware support unit is only required to be able to set dishes such as small dishes using the upper space, and various specific configurations are conceivable, and the specific configuration of the tableware basket and the shape of the tableware support that directly supports the tableware Also, various modifications may be made without departing from the scope of the present invention.
