[0010]
DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 of the present invention is a cleaning pump for pressurizing cleaning water, a plurality of cleaning means having an injection port for injecting cleaning water, and a cleaning means to which cleaning water is supplied from the cleaning pump. The water diverting means includes an inflow portion into which the wash water flows, a casing having a plurality of outflow portions, a valve body provided with an opening through which the wash water passes, and the valve A body and an engaging portion provided on each casing, and the valve body is provided so as to advance and retreat with respect to the outflow portion by intermittent operation of the cleaning pump. When the valve body and the engaging portion of the casing engage with each other, the valve body rotates to sequentially switch the matching portion of the opening portion of the valve body and the outflow portion that supplies the cleaning water. The cleaning means is connected to each of the cleaning paths, and Two or more outlet portions one of said plurality of outlet portions by coupling either two or more cleaning path of the pieces of the cleaning path has been connected to the same cleaning means, certain By spraying the cleaning water multiple times from the cleaning means, the cleaning power can be increased and decreased in the cleaning tank, and it is possible to set highly dirty dishes in a strong place, or it is difficult to remove dirt such as teacups More efficient cleaning corresponding to the strength of dirt can be performed, for example, it is possible to lengthen the spraying time for spraying the region.
[0011]
According to a second aspect of the present invention, in the first aspect of the present invention, the plurality of injections from the specific cleaning means performed during one cycle of switching of the water distribution means are not continuous, but the intervals between the injections. When cleaning progresses due to the swelling action of detergent or cleaning water, such as rice grains, the interval between spraying is shortened and cleaning water is placed around the dirt. It is advantageous to keep an abundant state for a long time, and by performing injection without being continuous in one cycle, the interval between injection and injection can be shortened, and the cleaning performance can be further improved.
[0012]
A third aspect of the present invention is the invention according to the first or second aspect, further comprising a tableware basket in which an object to be cleaned is set, and the number of times of spraying from a cleaning means for spraying cleaning water from below the tableware basket. When spraying wash water from multiple directions, spraying from the bottom of the tableware basket is a short distance from the tableware and enables strong cleaning, so it removes dirt from the tableware. In particular, spraying from the cleaning means disposed above the tableware is an effective cleaning method that is used to wash away the reattached particles, etc., so that the number of sprays from below is maximized. As a result, the energy can be more concentrated and the cleaning can be performed more strongly, the dirt can be removed in a shorter time, and more efficient cleaning can be performed.
[0013]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0014]
Example 1
As shown in FIGS. 1 to 5, the dishwasher main body 20 is provided with a washing tub 22 that can be opened and closed by a door 21, and an object to be cleaned 23 such as tableware is set in a tableware basket 24 and accommodated in the washing tub 22. is doing. A water supply valve (not shown) supplies cleaning water to the cleaning tank 22, and a cleaning pump 26 pressurizes the cleaning water and supplies it to a cleaning means (cleaning nozzle) 27 provided with a plurality of injection holes. Washing water is jetted from the washing means 27. The cleaning means 27 is installed in three places, 27a and 27b sprayed from the lower side of the tableware basket 24, and 27c sprayed from the back surface. Each of the cleaning means 27 is provided with about 4 to 10 injection ports for injecting cleaning water.
[0015]
The bottom of the cleaning tank 22 has a drain port 28 communicating with the suction side of the cleaning pump 26. The drain port 28 is provided with a residue filter 29 for collecting residue and a heating element 30 for heating. A temperature sensor 31 for detecting the temperature of the tank 22 is provided. The drainage pump 32 discharges the cleaning water in the cleaning tank 22. The blower (not shown) sends air to the cleaning tank 22 through a blower path (not shown) and discharges the exhaust from the exhaust port 35.
[0016]
The discharge path 36 of the cleaning pump 26 is provided with a water distribution means 37 for selectively switching the cleaning means 27 for supplying the cleaning water. The water distribution means 37 has the structure shown in FIGS. ing. A casing 40 having an inflow portion 38 into which cleaning water pressurized by the cleaning pump 26 flows, and four outflow portions 39 respectively communicating with the four cleaning means 27, and a valve body movably provided in the casing 40 41, and the valve body 41 is provided with an opening 42 through which washing water passes. A set of upper engaging portions 44 that rotate the valve body 41 by a predetermined angle when the valve body 41 is raised, and a set of lower engaging portions 45 that rotate the valve body 41 by a predetermined angle when the valve body 41 is lowered. Are respectively installed on the casing 40 side and the valve body 41 side.
[0017]
FIG. 5 is a view as seen from the lower side of the valve body 41. The outflow portions 39 are each connected to the cleaning means 27 by the cleaning path 43, and among these, the cleaning path 43 is connected to the outflow portions 39a and 39c. Are connected together and connected to the cleaning means 27a.
[0018]
One cleaning means 27 refers to an assembly of injection ports through which cleaning water that has passed through one outflow portion 39 is jetted, and is not limited to one rotating nozzle or one fixed nozzle. Various configurations are conceivable, such as when there are a plurality of nozzles, a combination of rotating nozzles and fixed nozzles, or when the location of the injection port is remote. In any case, one cleaning means 27 is used. There is no difference.
[0019]
3 is a conceptual diagram of the water diversion means 37. In practice, the casing 40 has a structure in which the casing 40 is divided into two parts in the vertical direction and joined by screwing, fitting, welding, welding, or the like. Further, when the cleaning tank 22 is made of resin, a part of the casing 40 can be formed integrally with the bottom surface of the cleaning tank 22.
[0020]
In the above configuration, first, the basic operation of the dishwasher will be described. An object to be cleaned 23 such as tableware is set in a tableware basket 24 and stored in the washing tub 22, and after the detergent is put in, the door 21 closes the opening of the dishwasher body 20 and starts operation. A cleaning process for removing dirt on the object to be cleaned 23, a rinsing process for pouring the attached detergent and leftovers, and a drying process for drying the water suitable for the object to be cleaned 23 are performed in this order.
[0021]
First, the water supply valve is operated to supply a predetermined amount of cleaning water to the cleaning tank 22, and then the cleaning water is pressurized by the cleaning pump 26, and the cleaning water 27 is jetted from the cleaning means 27. At this time, the heating process is performed while heating the heating water by energizing the heating element 30 such as a sheathed heater provided in the cleaning tank 22. Further, the temperature sensor 31 detects the temperature of the cleaning tank 22 and stops the energization of the heating element 30 when the temperature becomes higher than a predetermined temperature.
[0022]
The washing water passes through the residual filter 29 and is sucked into the washing pump 26, supplied to the washing means 27 provided in the washing tank 22 from the washing pump 26, and sprayed into the washing tank 22 to wash the dishes 23. Then, it circulates along the route of returning to the drain port 28 again. At this time, the residue dropped from the tableware 23 flows into the residue filter 29 together with the washing water, and the residue having a size that cannot pass through the residue filter 29 is collected by the residue filter 29.
[0023]
When the cleaning process for a predetermined time is finished, the cleaning water containing dirt is discharged out of the apparatus by the drain pump 32, and the cleaning water is newly supplied. The washing pump 26 is operated, and washing water is again sprayed from the washing nozzle 27 to rinse the article 23 to be washed, such as detergent and leftovers. After the operation for a predetermined time, the operation of discharging the cleaning water and supplying the cleaning water again is repeated, and this rinsing process is continuously performed about three times. Finally, the washing water is discharged outside the apparatus, and the rinsing process is completed.
[0024]
Subsequently, by performing a drying process and operating the blower, the outside air is blown into the cleaning tank 22 through the blower path and is discharged from the exhaust port 35. At this time, the heating element 30 is energized, and evaporation of water droplets adhering to the object to be cleaned 23 is promoted by the effects of both air blowing and temperature. These drying steps are performed for a predetermined time, and the operation is terminated.
[0025]
Next, the operation and action of the water distribution means 37, which is a characteristic configuration of the present embodiment, will be described. As shown in FIGS. 3 and 4, the casing 40 has a substantially cylindrical shape, the axial direction of which is arranged in a substantially vertical direction, and an inflow portion 38 into which the cleaning water pressurized by the cleaning pump 26 flows is a casing. The outflow part 39 is installed on the upper surface of the casing 40 at the lower end part of 40. The valve body 41 has a substantially planar shape, and the opposing surfaces of the outflow portion 39 and the valve body 41 also have a planar shape.
[0026]
When the cleaning pump 26 is operated, the valve body 41 rises by an operation accompanied by substantially linear motion and rotation according to the inclination of the upper engaging portion 44 due to the pressure of the cleaning water flowing in from the inflow portion 38, and is shown in FIG. 3. As described above, the predetermined outflow portion 39 is fixed at a position where it opens, and the cleaning water is jetted from the cleaning means 27 communicating with the outflow portion 39. When viewed from the lower side of the valve body 41, as shown in FIG. 5, the upper engaging portion 44 so that the opening 42 provided at the position where the washing water passes through the valve body 41 coincides with the predetermined outflow portion 39. (The details of the engaging portion are not shown in the sectional view, see FIG. 8).
[0027]
Subsequently, once the washing pump 26 is stopped, the pressure that has pushed up the valve body 41 from below does not act, so the valve body 41 falls by its own weight, but at this time, according to the inclination of the lower engagement portion 45 The robot descends while rotating and stops at a predetermined position as shown in FIG. When the cleaning pump 26 is operated again, it is engaged with the next inclination of the upper engaging portion 44, the valve body 41 rises while rotating, and communicates with the next outflow portion 39, whereby the next cleaning means 27. The washing water is sprayed from.
[0028]
Since the outflow portions 39a and 39c are both connected to the cleaning means 27a, by operating the cleaning pump 26 intermittently, as shown in FIG. Switching in the order of → 27a → 27c. This is one cycle of switching in which the valve body 41 makes a round, and the injection continues while repeating this injection pattern. That is, one cycle means that the switching of the cleaning means 27 by the water distribution means 37 is completed.
[0029]
By these actions, the cleaning water is not supplied to the three cleaning means 27 at the same time, but the cleaning water is sequentially fed, so that an arbitrary amount of water to be cleaned 23 can be increased from a plurality of directions without increasing the amount of water supply. Wash water can be jetted. Therefore, contaminants attached to the tableware 23 and the like can be cleaned in a short time, and high-efficiency cleaning can be realized.
[0030]
In addition, in comparison with the case where a plurality of cleaning means 27 are simultaneously injected, it is possible to inject only from one cleaning means 27 at a high pressure, and the cleaning power can be further enhanced.
[0031]
Further, the cleaning means 27a jets the cleaning water twice in one cycle, and the cleaning power of the portion hit by the cleaning means 27a is twice as high as the others, and this part is concentrated. Can be washed. In other words, by making a difference in the number of sprays from the cleaning means 27 in one cycle, it is possible to perform optimal cleaning according to the level of dirt, so it is recommended to set dishes with severe dirt on this strong part. Therefore, more efficient cleaning can be performed.
[0032]
Further, in the tableware used as a standard, the tea bowl 23A with the possibility that the rice grains are stuck is most difficult to clean, and as shown in FIG. By increasing the number of times of injection from the cleaning means 27a, the cleaning efficiency is further increased.
[0033]
Thus, if the outflow part 39 and the cleaning path 43 are set arbitrarily, the valve body 41 is injected into the cleaning tank 22 only by switching at regular intervals without using a detection means for detecting the injection position. The cost and space for installing the detection means can be omitted, and the position of the strength is shifted due to erroneous detection by the detection means, and there is no fear that the cleaning performance will be significantly reduced.
[0034]
In addition, it does not limit which cleaning means 27 injects several times, Moreover, the effect is exhibited also in the structure injected in multiple times from several cleaning means 27. FIG.
[0035]
Further, as shown in FIG. 7, a plurality of injections performed during one cycle of switching of the water distribution means 37 are performed without being continuous. When washing progresses due to the swelling action of detergent or washing water, such as rice grains, it is advantageous to shorten the interval between jets and keep the state where there is plenty of wash water around the dirt. , 27a → 27a → 27b → 27c → will not be injected into the bowl 23A during the two steps 27b → 27c, but 27a → 27b → 27a → 27c → By doing so, the interval between injection and injection is only one step, and the cleaning performance can be further improved.
[0036]
In addition, instead of jetting in the order of FIG. 7, the outflow portions 39a and 39b in FIG. 5 are connected and connected to the cleaning means 27a, and even if jetted in the order of 27a → 27a → 27b → 27c →, the cleaning efficiency is improved. It goes without saying that can be achieved.
[0037]
When spraying wash water from multiple directions, the spray from the cleaning means 27a and 27b below the tableware basket is used for peeling dirt from the tableware because the distance from the tableware is short and strong cleaning is possible. The spraying from the cleaning means 27c disposed above the tableware is an effective cleaning method that is used to wash away the reattached particles and the like, so that the number of sprays of the cleaning means 27a sprayed from below is maximized. By doing so, energy can be concentrated and washing | cleaning can be performed strongly, and dirt can be removed in a short time.
[0038]
In addition, the increase in cleaning efficiency means that the detergent or residue adhering to the tableware can be rinsed in a short time, and the number of times of rinsing can be reduced. For example, it is possible to reduce the number of rinsing steps performed four times to three. 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 the heater can be shortened, and energy saving and water saving can be realized.
[0039]
In addition, since the cleaning water can be sprayed from multiple directions to the object to be cleaned 23, the user can set the position of the object to be cleaned 23 on the tableware basket 24 and the setting method such as the vertical placement and the face down placement. Since it can be set freely without choosing, it can be a dishwasher with better setability. Furthermore, sufficient washing performance can be exerted even for tableware such as a bowl, a deep bowl, a dish, etc., in which washing water is not sufficiently delivered by spraying from a single direction.
[0040]
In addition, if the time of spraying from one cleaning means 27 is switched from several seconds to several minutes, efficient cleaning can be performed. However, at least one cleaning means is used at least once during one cleaning or rinsing process. It is desirable to set so that the fuel is ejected from 27. Therefore, it may be set to about 10 seconds to 1 minute.
[0041]
Further, the switching of the cleaning means 27 for injecting the cleaning water is performed by intermittent operation of the cleaning pump 26, which does not require a reduction in the electric drive of a three-way valve, an electric motor or the like, is inexpensive, and has a water distribution means 37. Can be reduced in size.
[0042]
In the case of motor drive, the rotating shaft needs to be installed through the casing 40, and it is necessary to provide a dense sealing means. At the same time, the structure becomes complicated. Although there was a possibility of causing water leakage to the outside, in this configuration, there is no part that operates through the casing 40, and there is no possibility of causing water leakage to the outside.
[0043]
The relationship between the circular upper engaging portion 44 and the lower engaging portion 45 extended to a plane is shown in FIG. 8. By repeating the operation and stop of the cleaning pump 26, the vertical vertical direction is substantially straight. The position of the valve body 41 is sequentially switched while performing an operation combining the movement and the rotational movement. In the present embodiment, the valve body 41 is rotated 90 degrees by one stop and operation in order to switch to the four outflow portions 39.
[0044]
The upper engaging portion 44 and the lower engaging portion 45 are not limited to this configuration, and when the cleaning pump 26 is operated intermittently, the predetermined outflow portion 39 and It is only necessary that the opening 42 of the valve body 41 coincides. For example, the valve body 41 hardly rotates when the valve body 41 is lowered, rotates about 90 degrees when the valve body 41 is lifted, or conversely rotates about 90 degrees when the valve body 41 is lowered. The structure which does not do may be sufficient. Further, instead of the triangular claw portion shape, as shown in FIG. 9, the groove portion 46 may be configured by the shaft portion 47. Further, the same operation can be obtained even if the engaging portion is provided on the outer peripheral portion of the valve body 41.
[0045]
In the case of the engaging portion shown in FIG. 8, the valve body 41 does not come into contact with the outflow portion 39 while rotating, there is almost no wear on the contact surface, and wear-resistant material is used. There is no need, and a general resin molded product such as PP or POM can be used.
[0046]
Also, with this configuration, cleaning water that flows with foreign matter 49 such as residue and toothpicks is circulated, and even when foreign matter 49 enters the gap between the casing 40 and the valve body 41, the cleaning pump 26 is stopped and the valve When the body 41 leaves, the foreign matter 49 can be removed from the gap. For this reason, the foreign object 49 is caught in the gap, and the valve body 41 is not made immovable, and the valve body 41 can be switched reliably.
[0047]
In this embodiment, there are three cleaning means 27 and the spraying is performed in the order of 27a → 27b → 27a → 27c →. However, the number of cleaning means 27 and the spray pattern are not limited, and the arrangement of the dishes is not limited. Various combinations according to the above are conceivable, and the effect can be exhibited.
[0048]
For example, as shown in FIG. 10, when four cleaning means 27 are provided, two on the bottom of the cleaning tank (27a, 27b), one on the left side (27c), and one on the right top (27d) Or when two (27a, 27b) cleaning means are installed on the bottom of the cleaning tank as shown in FIG. 11 and two (27c, 27d) cleaning means are installed on the back, or two upper and lower tableware baskets as shown in FIG. And two cleaning means (27c, 27d) are provided between them, and spraying can be carried out in a pattern such as cleaning means 27a → 27a → 27b → 27c → 27d →. By applying strength, the same effect can be obtained.
[0049]
If the number of the cleaning means 27 is two or more, the effect is exhibited. However, it is important to improve the cleaning performance that the injection from two or more directions with respect to a certain object 23 is obtained. When the tank 22 has a substantially cubic shape, it is desirable to have two or more locations, and when the tank 22 has a rectangular parallelepiped shape, it is desirable to have three or more locations. On the other hand, if the number of branches is too large, the total amount of water sprayed from one cleaning means 27 becomes small and the cleaning effect is diminished, so it is desirable that the number is 10 or less, preferably 6 or less.
[0050]
The cleaning pump 26 is configured to repeat operation and stop. However, when using a pump that can vary the pump output, such as the cleaning pump 26 using an inverter motor, the strength of the pump output is used. Thus, the valve body 41 can be switched. If the output at the time of weakness is set to be equal to or less than the output at which the valve body 41 is separated from the outflow portion 39, the output can be switched, and the number of times of operation and stop of the pump is reduced. It also leads to noise reduction. In addition, by changing the output of the injection for each cleaning means 27 to be injected, it is possible to perform arbitrary injection according to the level of dirt.
[0051]
The present invention relates to a washing water switching method, and does not limit the shape and size of the dishwasher body 20, the door opening / closing method, the arrangement of dishes, the arrangement of individual components, and the like. Moreover, in Example 1, although the example of the dishwasher which has a drying function was shown, the same effect is acquired also in the dishwasher which does not accompany a drying function.
[0052]
(Example 2)
FIG. 13 is a view of the water diversion means 37 having a different configuration, as viewed from the lower side of the valve body 41. The valve body 41 has a cylindrical shape, an opening 42 is provided in the cylindrical portion, and the outflow portion 39 is also provided in the cylindrical portion of the casing 40. There are six outflow portions 39 from the casing 40, and the outflow portions 39a, 39b, 39c and 39c, 39d are connected immediately after exiting the casing 40, and are connected to the three cleaning means 27 as shown in FIG. ing. Other basic configurations are the same as those in the first embodiment.
[0053]
By using the water diversion means 37 as shown in FIG. 13, the injection pattern is 27a → 27a → 27a → 27b → 27b → 27c → as shown in FIG. This is an injection emphasizing the injection from below the cleaning basket 24.
[0054]
Moreover, the injection from 27a and 27b is performed continuously in one cycle. Even if a part of the dirt having adhesiveness to the tableware is peeled off and the washing water enters, if the spraying stops, it comes into close contact again and cannot be completely removed. For this reason, it is effective for the washing to keep washing water until it can be completely peeled off. By continuously spraying from the same washing means, the dirt once removed will come into close contact with the dishes. Before, the probability of removing the dirt becomes high, and it is possible to clean more efficiently and in a short time.
[0055]
Further, the outflow portions 39a, 39b, 39c and 39c, 39d are connected immediately after leaving the casing 40, so that the structure can be simplified and the space around the washing path 43 can be omitted, and the dishwasher itself of the apparatus itself The size can be reduced.
[0056]
Example 3
FIG. 15 shows an example in which the drive motor 54 is used to drive the valve body 41, and the other basic configuration is the same as that of the first embodiment.
[0057]
The valve element 41 shown in FIG. 5 or the like is rotated by the drive motor 54 in the direction of the arrow. If the electric motor 54 is continuously driven at a constant speed, the same cleaning effect as in the first embodiment can be obtained. In the configuration as in the conventional example of FIG. 21, it is necessary to stop the valve body at an arbitrary position in order to use the position detection unit and change the injection time for each cleaning unit, but in this configuration, a sensor or the like is used. Therefore, the cleaning power in the cleaning tank can be increased and decreased to be cleaned efficiently.
[0058]
When the electric motor 54 is used, there is an advantage that the valve body 41 can be reliably rotated even when cleaning water containing foreign matter such as residue flows in.
[0059]
In the case of switching by driving the electric motor 54 continuously, there is a possibility that the two cleaning means simultaneously inject at the intermediate position of rotation, but this is the same condition for all the cleaning means 27, and If the injection in the state where the opening 42 and the outflow portion 39 coincide is considered in the state, the injection performance can be determined in the same manner as in the case where the outflow portion 39 is switched discretely.
[0060]
Example 4
FIG. 16 is a view as seen from the lower side of the valve element 41. The opening 42 of the valve element 41 has a notch shape connected to the outer shape of the valve element 41, and the outflow part 39 from the casing 40 has a substantially fan shape. The opening 42 opens the two outflow portions 39 simultaneously.
[0061]
Moreover, the cleaning means 27 is the same three places (27a, 27b, 27c) as Example 1, and the outflow parts 39a and 39b are connected and connected to one cleaning means 27a. Other basic configurations are the same as those in the first embodiment.
[0062]
Similar to the first embodiment, the valve body 41 is rotated by 90 degrees by the operation / stop operation of the cleaning pump 26, and the opening 42 of the valve body 41 is configured to supply cleaning water to the two outflow portions. Therefore, the injection pattern when the cleaning pump 26 is operating is as shown in FIG. 17, and there are a case where the injection is performed from only one cleaning means 27 and a case where the two cleaning means 27 are simultaneously injected. Even in the case of simultaneous injection at two locations, the amount of water can be reduced as compared with the case of injection from all three cleaning means 27, and the use of the water diversion means 37 can also exhibit advantages.
[0063]
Even in this spray pattern, the number of sprays from each cleaning means 27 is 3 times from 27a, 2 times from 27b, and 2 times from 27c, and there is a difference in the number of sprays. You can wash more efficiently by adding the strength of the jet to the table and installing highly dirty dishes in a specific place, or by increasing the number of injections of the site where you mainly set bad dishes with teapots etc. The same effect as in Example 1 can be obtained.
[0064]
In addition, it is not necessary to change the number of times of spraying from each cleaning means, and the same number of times of spraying cleaning means may exist, and each number of times may be set according to the tableware arrangement or the like.
[0065]
Further, when the shape of the outflow portion 39 is changed as shown in FIG. 18, it can be injected in a pattern as shown in FIG. 19, and each of the three places is injected independently, and the cleaning means 27a and 27b below the tableware basket 24 are used.
