However, in the conventional dishwasher / dryer, the washing nozzle can be sprayed only from a fixed spraying direction for various dish shapes used in ordinary households, so that sufficient washing performance can be obtained. Not.
Tableware with a thread bottom, such as a cup of tea or a soup bowl, tends to accumulate fine residue on the thread bottom without spraying from the top of the washing tank, and also tends to cause poor rinsing due to insufficient rinsing water. . And to solve these,
As shown in JP-A-5-305050, it is conceivable to inject washing water from multiple directions using a plurality of washing nozzles. The amount of water supplied to the washing tank must be increased.

[0007] That is, an increase in the amount of supplied water increases the temperature rise time of the washing water, resulting in an increase in operating time, an increase in power consumption, an increase in the amount of water used, and a large washing pump is required. Therefore, various problems such as an increase in cost and an increase in noise and vibration caused by spraying a large amount of cleaning water at a time occur.

As disclosed in Japanese Patent Application Laid-Open No. 5-176875, a solution to these problems has been proposed by using a plurality of washing pumps. However, a washing pump is required for each washing nozzle, and dishwashing and drying are performed. Since the volume of the washing mechanism occupying the entire machine increases, there is a problem that a sufficient volume for dishwashing cannot be secured or the dishwasher body becomes unnecessarily large.

Furthermore, as shown in Japanese Patent Application Laid-Open No. Hei 6-30853, a configuration in which a three-way valve is frequently used to divide water is conceivable. However, a dishwasher that handles cleaning water containing residual vegetables and foreign substances is not applicable. , The operation reliability of the valve mechanism is difficult to ensure, the number of three-way valves increases when the number of diversion channels increases, and it is not possible to cope with the complicated way of discharging cleaning water to each cleaning nozzle. In addition, there are problems such as generation of a peculiar noise at the time of valve operation or an increase in cost.

[0010]

FIG. 9 shows an example of a dishwasher / dryer comprising only a water separating device (not shown) and a plurality of fixed nozzles 58, 59, 60.

The basic operation as a dishwasher / dryer is the same as that of a conventional dishwasher / dryer, and the description is omitted here.

Next, the operation and operation of the water diversion device 35, which is a characteristic configuration of the present embodiment, will be described. Cleaning pump 28
The cleaning water pressurized by the above flows through the water guide section 39 and is discharged from a discharge port 41 provided in the rotary water distribution section 40. At this time, since the rotary water diversion unit 40 is rotated by the driving motor 42, the cleaning water discharged from the discharge ports 41 is sequentially discharged from the five water diversion discharge ports 44 and the respective cleaning nozzles are discharged. Sent to That is, the cleaning water is sent in the order of the cleaning nozzle 29 (lower surface), the right side cleaning nozzle (not shown), the cleaning nozzle 32 (left side), the cleaning nozzle 31 (back surface), and the cleaning nozzle 30 (upper side). is there. As described above, the cleaning water is not supplied to the five cleaning nozzles at the same time, but is sequentially supplied to the cleaning nozzle. Therefore, the cleaning water is supplied to the object to be cleaned from a plurality of directions without increasing the water supply amount. Can be fired.

Therefore, it is possible to realize high-efficiency cleaning in which contaminants adhered to tableware and the like can be cleaned in a short time. In addition, detergents and contaminants adhering to tableware and the like can be rinsed in a short time, so that the number of times of rinsing can be reduced. Furthermore, since the number of times of rinsing can be reduced without increasing the amount of water supplied at one time, the heating time of the cleaning water using a heater can also be shortened. Therefore, energy saving and water saving can be realized.

Further, since the number of washing nozzles can be increased without increasing the amount of water supplied, a washing system in which washing water is sprayed from more directions to an object to be washed such as tableware can be adopted. Therefore, the user can freely set the washing object without selecting the setting position of the washing object in the basket and the setting method such as the vertical setting, the face-down setting, and the like. Furthermore, a dishwasher / dryer that can exhibit sufficient washing performance even for a dish such as a square bowl, a deep small bowl, a square dish, and the like, in which washing water has not been sufficiently supplied by injection from a single direction, can be obtained.

The water diversion device 35 includes a cleaning discharge path 37.
Instead of using a switching valve or the like, a substantially cylindrical rotary water diversion section 40 and a water diversion take-out section 4 which are rotated by a driving motor 42
Since the cleaning and discharging paths 37 are switched between the three, a simple and highly reliable water diversion apparatus that does not cause a malfunction of the switching valve due to the entry of foreign matter in the cleaning water can be realized.

Also, for five water diversion outlets 44,
Since two outlets 41 are provided (water outlet 44
And the discharge port 41 have the same vertical and horizontal dimensions),
The cleaning water is simultaneously supplied to two (up to three) cleaning nozzles. Therefore, the rotary water diversion unit 4
The injection time during which each cleaning nozzle injects the cleaning water during one rotation of 0 is double that of the configuration in which the discharge port 41 is located at one place. At this time, the discharge pressure of the washing water slightly decreases,
Conventionally, the dishes in the upper dish basket (not shown) are washed only by the lower washing nozzle, whereas in the configuration of the present embodiment, the washing water is sprayed from the upper portion of the washing tank 22,
Detergency more than before can be secured. Therefore, it is possible to increase the amount of the jet cleaning water per unit time with respect to the object to be cleaned, and to improve the cleaning performance.

The driving motor 42 includes a control device 38.
Accordingly, the rotation speed of the rotary water diversion unit 40 can be set freely. For example, when the attached dirt is light, such as a cup used for a cup of tea or a salad, it is washed away immediately by spraying the washing water. Therefore, in this case, the rotation water diversion unit 4 is more expensive than the time required for jetting from one washing nozzle.
It can be said that it is a short and more efficient cleaning method to increase the rotation speed of 0 and to spray the cleaning water to the tableware from multiple directions per unit time. In addition, when washing dishes with a large amount of dirt and eggs or oil, contrary to the above, it is better to take a longer spraying time to spray from one washing nozzle while the rotating water diversion unit 40 makes one rotation. It goes without saying that the cleaning performance is higher than otherwise. As described above, by changing the amount of washing water jetted from each washing means in accordance with the amount and quality of contamination attached to washing dishes and the like, improvement of washing performance by optimization of washing performance, shortening of washing time, or Energy saving can be realized.

The drive motor 42 has a discharge port 41 of the rotary water diversion section 40 and five water diversion discharge ports 44 provided by a rotation detection disk 67, a rotation detection sensor 47 and a positioning fixed position sensor 48. Relative positional relationship with the user. So, for example, to reduce the cleaning time,
It is possible to make the injection time from the lower part of the cleaning tank 22 and the injection time from the upper part longer than the injection time from the other cleaning nozzles. In addition, in order to minimize the injection of the cleaning water to the lid, which causes the increase in the cleaning noise, it is possible to perform an operation in which the injection time from the back is shorter than the injection time of the other cleaning nozzles. As described above, it is possible to supply cleaning water to a specific cleaning discharge path for an arbitrary time, and it is possible to input cleaning energy corresponding to the degree of contamination of an object to be cleaned,
The cleaning performance can be improved. Further, washing noise can be reduced.

Further, since the drive motor 42 is controlled by the control device 38 to rotate forward and backward, it can freely rotate clockwise and counterclockwise. Therefore,
For example, in a dishwasher as shown in FIG. 8, when dishes are set only in the right half of the dish basket, washing is most efficiently performed by injecting washing water only from the washing nozzles 62, 64, and 66. be able to. At this time, if the rotary water diversion unit 40 rotates only in a single direction, the cleaning water is also supplied to the cleaning nozzles 61, 63, and 65 for cleaning the left side of the tableware basket in which the tableware is not set. Inefficient. However, in addition to the rotation detection sensor 47 and the positioning fixed position sensor 48, a driving motor
Since the controller 42 is controlled by the control device 38 to rotate forward and backward, the cleaning water can be supplied only to the cleaning nozzles 62, 64, and 66. Therefore, energy can be saved for a short time by efficient cleaning corresponding to the tableware setting position.

In the case of a cleaning system using a plurality of cleaning nozzles, a cleaning discharge path is required for each of them, and an increase in water supply cannot be avoided. Moreover, as shown in FIG. 9, when only the fixed nozzles are used, many injection ports 17 are required to secure a predetermined cleaning performance. However, in this embodiment, at least one of the plurality of cleaning nozzles, or a rotating nozzle that sprays the cleaning water while rotating all of the cleaning nozzles, can be used to reduce the amount of water to be cleaned with a smaller amount of water supply. Since washing water can be sprayed from multiple directions, tableware shape, tableware set position,
Irrespective of the setting method, highly efficient cleaning performance can be exhibited.

Further, the structure and configuration in which the number of discharge ports and the rotation speed and forward / reverse rotation of the driving motor, the rotation angle detecting means, or the washing nozzle is a rotating nozzle described in this embodiment are integrated. There is no necessity to carry out, and each can be carried out independently.

(Embodiment 2) A perspective view showing the structure of another washing means FIG. 10 is a sectional view of a dishwasher / dryer according to Embodiment 2 of the present invention. FIG. 11 is a partial cross-sectional view showing the structure of the water dividing means of the dishwasher and the flow of washing water.

The difference from the first embodiment is that, as shown in FIG. 10, one of the cleaning / discharging paths 37 is connected to a drain path 69, and the other cleaning / discharging path 37 is connected to a garbage collection. It has just communicated with the filter 70 (garbage collecting means). As shown in FIG. 11, a micro switch is provided for the rotation detecting sensor 71 and the positioning fixed position sensor 72 for detecting the fixed position of the rotary water diversion unit 40 and the rotation angle at the time of rotation. This is being realized by the combination of the detection disk 73. As a detection method, a sensor using magnetism can be considered in addition to the methods of the first and second embodiments.

Next, the operation and operation will be described. First, in the first embodiment, a separate drainage pump 33 is required.
9, the washing pump 28 can also serve as a drain pump 33. As the operation, the rotating diversion unit 40 is controlled so that the discharge port 41 does not rotate in the cleaning discharge path 37 communicating with the drain path 69 during the cleaning step, and the drain port 69 can be drained only during the drain step.

Therefore, since the number of drainage pumps can be reduced, it is possible to reduce the size of the product by reducing the volume of the cleaning mechanism, reduce the cost, or increase the cleaning volume in the same product volume. In addition, since a cleaning pump having a high discharge capacity is used, residual water is reduced by improving drainage performance, and accordingly, rinsing performance can be improved. A check valve (not shown) may be provided in the drainage path or a gap between the discharge port 41 and the water discharge port 44 may be provided to prevent the cleaning water from draining out of the apparatus during the cleaning process. −
In some cases, it is necessary to take measures such as

Further, since one of the cleaning discharge paths 37 is connected to a garbage collecting filter 70 (garbage collecting means) for collecting garbage in the cleaning water, the cleaning water is used in the cleaning step. A part can be collected in the garbage collection filter 70 from the above route. Further, by controlling the rotary water diversion unit 40, it is possible to lengthen the time for collecting the garbage, so that the garbage can be reliably collected. Further, in the final rinsing step, a cleaning discharge path 3 for collecting residual vegetables
By controlling the rotary water diversion unit 40 so that the washing water is not supplied to the dish 7, dishes and the like can be washed only with fresh water without washing water passing through the garbage. Therefore, it is possible to prevent reattachment to tableware due to residual vegetables, and to achieve a more hygienic washing finish.

The garbage collection and drainage configurations described in this embodiment need not be implemented integrally, but can be implemented independently.
