Description

dish washer

technical field

The invention relates to a tableware washing machine for washing and drying tableware and the like.

Background technique

A conventional dishwasher is shown in FIG. 3 , and its composition will be described below. In the existing dish washer, the body 1 of the dish washer is provided with a washing tank 3 for loading various kinds of tableware 2 . An opening 4 is provided on the front surface of the washing tank 3, and a door 5 is attached to this opening 4 to cover it. The door 5 is divided into an upper door and a lower door. A rotatable cleaning nozzle 6 for spraying cleaning water is provided at the bottom of the cleaning tank 3 . An example of this existing dishwashing machine is found in Japanese Patent Laid-Open Publication 2001-275915.

Since the basic operation of dishwashers is generally well known, it will only be briefly described below.

First, the user opens the machine door 5, and loads various kinds of dirty tableware 2 into the tableware basket provided in the washing tank 3 in the dish washer body 1 .

Then, close the machine door 5 and start the operation. After the operation starts, the first thing to do is the cleaning process. During the cleaning process, the heater (not shown) arranged at the bottom of the cleaning tank 3 heats the cleaning water, and the cleaning nozzle 6 sprays the heated cleaning water toward various tableware 2; The water rinses all kinds of tableware 2, and finally performs a drying process. At this point, the cleaning operation is also over.

However, in the existing dishwasher, since it is difficult to judge the situation inside the washing tank when the door is closed, it is necessary to show whether the operation stroke is in the washing process or in the rinsing process by some method. In addition, when checking whether all kinds of tableware are fully cleaned during the cleaning process, it is necessary to interrupt the cleaning operation process and open the machine door for verification, so the operation is very troublesome.

In addition, in order to see the internal situation clearly, although it is also conceivable to make the door with a transparent or translucent material, but in such an occasion, the internal situation will be exposed too much, and the user will see it during the cleaning process. There is a problem of giving a bad impression to the user in the state where a large amount of dirt washed from various tableware is mixed and dirty-looking washing water is circulated. Conversely, if the machine door is made translucent in order to prevent sewage from being seen, the internal conditions to be observed may become difficult to see clearly.

For this reason, it is conceivable to use a lighting device to irradiate the interior, and make the lighting device emit light when necessary so as to see the internal situation clearly. Although there is no problem when you want to see the local situation clearly, in order to be able to see the largest possible range in the cleaning tank, the transparent window needs to be enlarged; when the transparent window is enlarged, the lighting is in a direction roughly perpendicular to the window When irradiating, in order to irradiate the entire area you want to observe, you need to install multiple lights at multiple locations, and if you install it at one location, you need to install a high-power lighting that can illuminate the entire space. In this way, there is a problem that not only the manufacturing cost increases, but also the long-term use cost will correspondingly increase.

Detailed ways

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a side sectional view of a dishwasher in one embodiment of the present invention, and Fig. 2 is a front view thereof. As shown in Fig. 1 and Fig. 2, a washing tank 9 for various tableware 8 is provided in the body 7 of the dish washer. An opening portion 10 is formed on the front surface of the cleaning tank 9, and this opening portion 10 is covered by a door 20. As shown in FIG. Moreover, the door 20 is divided up and down, and is comprised by the upper door 11 and the lower door 12. As shown in FIG.

A rotatable cleaning nozzle 13 for spraying cleaning water and an atomizing device 14 for atomizing the cleaning water are provided at the bottom of the cleaning tank 9 . The atomizing device 14 can be constituted by, for example, a vibrating device such as an ultrasonic oscillator. The upper machine door 11 and the lower machine door 12 are horizontally long rectangles. In order to see clearly the internal situation of the cleaning tank 9, the upper door 11 is provided with a horizontally longer rectangular window 15. The window 15 is made of a transparent or translucent material such as flat glass, a plastic plate with excellent heat resistance, and the like.

In this embodiment, a mounting member 16 is provided on the top surface of the cleaning tank 9 and close to the side. The mounting member 16 is provided with an illuminating device 17 for illuminating the inside of the cleaning tank 9. Specifically, the illuminating device 17 is installed in the installation hole on the installation member 16 that is positioned at the top surface of cleaning tank 9. In addition, the illuminating device 17 is provided with a transparent cover 18 protruding into the cleaning tank 9 and an illuminating lamp 19 constituting a light source. The illuminating lamp 19 is provided so as to protrude into the inside of the washing tank 9 , and emits light substantially parallel to the window 15 through the transparent cover 18 . That is, the radiated light is in the longitudinal direction of the window 15, and is irradiated in the left-right direction when viewed from the front. As shown in Figure 2, the lighting device 17 in this embodiment is arranged on the left side of the top surface when viewed from the front, and the light emitted is emitted from the left side to the right, and the inside of the cleaning tank 9 is illuminated. . Certainly, this illuminating device 17 also can be arranged on (when viewed from the front) the right side of the top surface, the light that irradiates is emitted from the right side to the left, and the inside of the cleaning tank 9 is illuminated. In addition, the lighting device 17 may also be provided on or near the side of the body. Here, the illuminating device 17 is preferably arranged near the short side of the rectangular window 15, because after being arranged like this, the entire field of vision in the window 15 can be illuminated efficiently.

The lighting device 17 is linked with the power supply of the atomizing device 14, so that the illuminating lamp 19 can be illuminated only when the atomizing device 14 is working.

The operation and effect in the above constitution will be described below. When the operation starts, the user first opens the machine door 20, and loads all kinds of dirty tableware 8 into the tableware basket arranged in the cleaning tank 9 in the dishwasher body 7. In addition, at least one of the upper door 11 and the lower door 12 of the door 20 is opened according to different usage conditions.

Next, add cleaning agent in the atomizing device 14, then close the machine door 20, and start the operation. After the operation starts, the first thing to do is the atomization stroke. In the atomization process, the cleaning water containing the cleaning agent is atomized by the atomizing device 14, so that the cleaning agent solution is attached to various tableware 8, and the attached cleaning agent solution can make the dirt float from the various tableware 8 rise. After the atomization stroke, the cleaning stroke is performed. During the cleaning process, the heater (not shown) arranged at the bottom of the cleaning tank 9 heats the cleaning water, and the cleaning nozzle 13 sprays the heated cleaning water toward various tableware 8, and the various tableware The dirt on the tableware 8 is washed off. Afterwards, after washing and drying the various tableware 8, the operation is over.

During the atomization process, the lighting device 17 and the operation of the atomization device 14 synchronously light up the lighting lamp 19 to illuminate various tableware 8 . At this time, the light irradiated from the illuminating lamp 19 is irradiated substantially parallel to the laterally long substantially rectangular window 15 provided on the upper door 11 from the vicinity of the side of the washing tank 9, so that the light from the lateral direction of the window 15 can be The longer side-to-side shines from one end to the other. In this way, the inside of the cleaning tank 9 that can be seen from the window 15 can be illuminated with high efficiency with only a minimum of one light source. Therefore, not only the manufacturing cost of the lighting device 17 can be reduced, but also the power consumption of the lighting lamp 19 and the lighting device 17 can be reduced.

In addition, in this embodiment, although the window 15 on the upper machine door 11 is made into a horizontally long rectangle, if the window 15 is made into a different vertically long rectangle, by making the lighting The lamp 19 is irradiated substantially parallel to the longitudinal direction, and the same lighting effect can also be achieved. In addition, by illuminating the inside of the cleaning tank 9 with the illuminating device 17, it is possible to clearly check the atomization of the cleaning solution which is difficult to see when the window 15 is translucent.

In addition, when the window 15 is made transparent, the light from the outside will be reflected by the window 15, and the inside of the cleaning tank 9 will become difficult to see clearly. By illuminating with the illuminating device 17 as in this embodiment, the visibility of the inside of the cleaning tank 9 can be improved.

In addition, in the cleaning tank 9 , the atomizing device 14 is arranged at the bottom, and the lighting device 17 is arranged above the cleaning tank 9 . After adopting such a configuration, it is easier to see that the cleaning liquid mist generated by the atomizing device 14 rises from the inner bottom of the cleaning tank 9 and then fills the inside of the cleaning tank 9 .

In addition, the lighting device 17 is only turned on during the atomization process. In this way, during the cleaning process, the illuminating device 17 can be prevented from being turned on arbitrarily, causing the user to see the very dirty washing water mixed with a large amount of dirt washed from various tableware 8 and causing uncomfortable feeling. In addition, a switch can also be added, so that the user can easily change the on/off state of the lighting device 17, which will be more convenient to use. For example, when the switch is set to "off", it becomes the mode in which the lighting device 17 is only illuminated during the atomization stroke; Of course, it is no problem to set it to the opposite mode. In addition, it is also possible to provide a control unit (not shown) for interlocking the on/off of the lighting device 17 with the operation of the atomizing device 14 .

As described above, the dishwasher of the present embodiment is provided with a washing tank having an opening on the front surface, a door for opening/closing the opening, and a light inside the washing tank for illuminating the inside of the washing tank. In the lighting device, a part of the machine door is provided as a transparent or translucent window through which the inside of the washing tank can be seen, and at the same time, the lighting device emits light substantially parallel to the window. In this way, the interior of the cleaning tank that can be seen from the window can be illuminated with high efficiency by using few light sources, which not only reduces the manufacturing cost of the lighting device, but also reduces the power consumption of the lighting device when it is illuminated.

In addition, by installing the illuminating device on or near the side of the washing tank, the illuminating lamp can be irradiated substantially parallel to the window.

In addition, by installing the atomizing device for atomizing the cleaning solution at the bottom of the cleaning tank, it is easy to confirm the condition of the cleaning solution mist that is difficult to see when it is translucent and without lighting.

In addition, by arranging the lighting device above the atomizing device, it is easier to see clearly that the cleaning liquid mist generated by the atomizing device rises from the bottom of the cleaning tank and fills the cleaning tank.

In addition, by setting the lighting device to be on only during the operation of the atomizing device, it is possible to prevent the washing process from dissolving a large amount of dirt from all kinds of tableware and becoming very dirty during the cleaning process performed after the atomizing process. The washing water is seen by the user, causing discomfort.

To sum up, the dish washing machine of the present invention uses only a few light sources to illuminate the inside of the washing tank that can be seen from the window with high efficiency, so that the inside of the washing tank can be seen clearly when necessary. Therefore, the present invention is very suitable for devices such as dishwashers in which a part of the door is provided with a transparent window through which the inside of the washing tank can be seen clearly.
