Description

  The present invention relates to a structure of a drawer type dishwasher, in particular, a left side filter filter outlet, and allows the left side filter to be taken out without pulling out the washing tank, thereby facilitating the removal of the left side filter, and the washing operation. After completion, it is possible to prompt the cleaning of the leftover filter by turning on the leftover filter cleaning lamp.

Built-in type dishwashers can be broadly classified into front-opening and drawer-types, and these have completely different basic structures, so the leftover filter removal structure for removing and cleaning the leftover filter is greatly different.
In the front opening type, the leftover filter is located lower than the lower end of the front door, so there is a leftover filter outlet on the front wall below the front door so that the leftover filter can be taken forward. It has become. And the concrete structure for that is various (for example, Unexamined-Japanese-Patent No. 7-284468, Unexamined-Japanese-Patent No. 2003-144373, Unexamined-Japanese-Patent No. 4-109924, etc.), and a leftover filter is taken out to a front wall There is also an auxiliary door for the purpose, and when the auxiliary door is opened forward, the leftover filter is drawn out forward to make it easy to put in and out (for example, Japanese Utility Model Publication No. 6-81452). ).

  On the other hand, in a drawer type dishwasher, the washing tub is open upward, and is largely pulled out forward. Therefore, the leftover filter is generally taken in and out from the upper opening of the washing tub (for example, a special dishwasher). In such a drawer-type dishwasher, an opening for removing the leftovers filter is provided at the bottom of the dish basket, and from this opening through the dish basket in the wash, the upper opening opens. It is necessary to put in and out, and it is not preferable for hygiene because it is not easy to put in and out the leftover filter, and there is a possibility that drops of leftovers may fall in the dish basket.

  In addition, in order to avoid the above-mentioned problems of the structure for putting in and out the leftover filter of the drawer-type dishwasher, an outlet is provided in the washing tank, and the leftover filter is taken in and out from here. Yes (Japanese Patent Laid-Open No. 2003-24259). This is as shown in FIG. 6, and the outline thereof is as follows. A leftover filter outlet / outlet (round hole) H is provided in the front part of the side wall of the washing tank 2 of the dishwasher body 1, and the washing tank is pulled out and the above-mentioned remaining residue is drawn. The vegetable filter 4 is taken in and out from the vegetable filter outlet H. The front door unit 3 is fixed to the front wall of the cleaning tank 2, and the cleaning tank 2 is put in and out with the handle 7 of the front door unit 3. When the washing tub 2 is pushed into the dishwasher main body 1, the front opening of the dishwasher main body is closed by the front door unit 3, and the upper opening of the washing tub 1 is interlocked with the operation of taking in and out the washing tub 1. And automatically closed with the inner lid in the dishwasher body.

The washing tub 2 is pushed into the main body of the dishwasher and locked, and a preparation is made such as selecting a washing course in the operation unit 5. When the start button 6 is pushed, water supply, washing, draining, rinsing, draining, drying Etc. are sequentially executed. When the predetermined program for the selected course is completed, the cleaning operation is automatically stopped.
When cleaning operation is performed, the leftovers are captured by the leftover filter, and if this is left unattended, there will be problems such as giving off a strange odor. I need to clean it.

[Problems of the prior art]
For the drawer-type dishwasher, the one that allows the leftover filter to be taken in and out from the opening at the bottom of the side wall of the washing tank has solved the above problem by taking in and out the leftover filter from the upper opening of the washing tank. There are other problems, such as:
In other words, in the drawer type dishwasher, there is a leftover filter in the bottom of the wash tank that is open at the top, so the leftovers caught by this are not easily noticeable, and it is not easy to put in and out. Since it is troublesome, as a practical problem, it is often the case that the tableware is not taken out after the cleaning operation is finished. Due to these various circumstances, it is often the case that the leftover filter is not cleaned and left as it is after the cleaning operation.

In order to prevent the above problems, it is necessary to make it easy to put in and out the leftover filter, and it is necessary to call attention to clean the leftover filter after the cleaning operation. To that end, we devised a structure for putting in and out the leftover filter so that the leftover filter can be put in and out with the washing tank pushed in, and this is detected when the leftover filter is left uncleaned. Therefore, some kind of contrivance is required to prompt the user to clean it.
JP-A-7-284468 JP 2003-144373 A JP-A-4-109924 Japanese Utility Model Publication No. 6-81452 JP 2003-520 A JP 2003-24259 A

This invention makes the following matter the subject 1 and the subject 2 for the purpose of eliminating the said problem of a drawer-type dishwasher.
Assignment 1
(1) Devise the removal structure so that the leftover filter can be easily and easily removed without pulling out the washing tank.
Assignment 2
(2) Take some measures to prompt the cleaning of the leftover filter immediately after the end of the cleaning operation.

Means for solving Problem 1 and Problem 2 are based on the following (a) to (e) on the premise of a drawer type dishwasher.
(A) A front door unit is provided at the front door of the cleaning tank so that it can be opened and closed, and a leftover filter outlet is provided at the bottom of the front wall of the cleaning tank.
(B) The front door of the washing tank is provided with an auxiliary door that opens and closes the above-mentioned leftover filter outlet,
(C) Auxiliary door operation detecting means for detecting the opening / closing operation of the auxiliary door is provided,
(D) A leftover filter cleaning lamp is provided on the front door indicator,
(E) The leftover filter cleaning lamp is turned on when the cleaning operation is finished, and the leftover filter cleaning lamp is turned off when the auxiliary door is opened.

In addition, the height position of the leftover filter extraction port may be a position where the leftover filter can be easily removed, and such a position is slightly higher than the leftover filter.
Further, the cleaning operation of the above requirement (e) does not include a cleaning operation in which no leftovers remain (for example, a cleaning operation in which only rinsing and drying are performed).

  By opening the front door unit of the washing tub with the washing tub pushed into the dishwasher body and opening the auxiliary door at the bottom of the front door of the washing tub, you can remove and insert the leftover filter from the leftover filter outlet. In addition, it is easy to put out and put in the leftover filter, and it can interfere with the dishes in the washing tub, the dishes in the dish basket, etc. Because there is no, it is possible to easily and easily take out and put in the leftover filter.

  When the cleaning operation is finished, the leftover filter cleaning lamp is lit on the front door indicator to prompt the user to clean the leftover filter. When the leftover filter is taken out, cleaned, stored again, and the auxiliary door is closed, this is detected by the auxiliary door operation detecting means. The auxiliary door is opened and closed only when removing the leftover filter, and the front door unit is opened and closed only when the auxiliary door is opened and closed. It can be considered that the auxiliary door is opened and closed by the detection signal, and the leftover filter is taken in and out.

  Note that the above-mentioned leftover filter cleaning lamp display is a display that alerts the user that the leftover filter has not been cleaned, so blinking lighting is more effective than continuous lighting, and the lighting time The alerting effect can be further enhanced by devising the lighting display method such as gradually reducing the blinking interval as the time elapses.

 In addition, the structure for opening and closing the auxiliary door and the operation for removing and inserting the leftover filter separately from the front of the dishwasher makes the operation of opening and closing the leftover filter easy. Since it is easy and easy and the above-mentioned take-out port is securely sealed, it is possible to reliably prevent water leakage due to poor mounting or poor sealing.

The leftover filter cleaning lamp is turned off by the auxiliary door operation detection signal.
In addition, when there is a possibility that the front door unit to be opened / closed may be opened / closed for other purposes, it is necessary to use detection means for directly detecting the opening / closing operation of the auxiliary door.
The leftover filter cleaning lamp is one of means for prompting the user to clean the leftover filter. As this means, in addition to a visually appealing display such as a character display and a blinking display, there is an audio display that appeals to hearing. However, since the voice display device may cause discomfort to the user, it is necessary to pay sufficient attention to this point, and it is preferable to use a rhythmical melody sound. This is because such a thing is not so harsh and rarely gives the discomfort of being forced. Since the preference for sound display varies depending on the person, voice display is an option, and those who desire it can select the melody according to their preferences, like the ringtone of a so-called mobile phone. Good.

Further, for example, when an audio display is adopted as an option, it is necessary that the audio display be clearly distinguished from an audio display informing the end of the cleaning operation, and for a while after the end of the cleaning operation. Then, for example (after several seconds), it is preferable to start a sound display prompting cleaning of the leftover filter.
When adopting a sound indicator instead of the leftover filter cleaning lamp, the sound indicator does not need to be provided in the upper part of the front door unit, and can be provided in the interior space of the front door. If it does so, a display will not stand out in appearance, Therefore, the freedom degree of selection of an arrangement position is large.

The front door unit can be opened and closed in the left-right direction with its side edge as a fulcrum, but if the front door unit is opened and closed in the front-rear direction with its lower end as a fulcrum, the front door unit Expanded horizontally in front. Then, when the leftover filter is taken out, even if a drop falls from the leftovers in the leftover filter, this drop will fall on the front door that is opened horizontally, so it will not stain the kitchen floor. .
The vegetable filter cleaning lamp is turned off on the condition that the auxiliary door is opened and closed, but when a predetermined time (for example, 10 minutes) has elapsed since the cleaning operation was finished and the vegetable filter cleaning lamp was turned on. So that it is turned off. For example, if the leftover filter cleaning lamp is not cleaned even after 10 minutes have passed since the leftover filter cleaning lamp illuminates, even if the leftover filter cleaning lamp continues to be lit, no actual effect is expected. Because.

  For example, when the dishwasher is set to automatically start after going to bed, there are cases where it is not possible to clean the leftover filter immediately after the washing operation is finished. In such a case, it is necessary to call attention to clean the leftover filter early in the next morning, because after that time, it is highly likely that the leftover filter will not be cleaned for a long time. Because it becomes. In preparation for such a case, the leftover filter is used for a predetermined time (for example, about 10 minutes) at a predetermined time (for example, about 30 minutes) from a predetermined time (for example, about 6:00 am) for a predetermined time (for example, about 2 hours). The cleaning lamp can be turned on, during which time reminders can be reminded to clean the leftover filter.

In the above case, it is better to use a voice display to call attention (a reminder to clean the leftover filter), but in that case, use a quiet melody sound suitable for the atmosphere in the early morning home. Good. Needless to say, this warning display is based on the condition that the dishwashing operation has been performed before that and the leftover filter has not been cleaned until then.
The “predetermined time” (for example, about 2 hours), the “predetermined interval” (for example, about 30 minutes), the “predetermined time” (for example, about 10 minutes), etc. can be adjusted to meet the user's wishes. It is good to set.

  In addition, the detection signal from the auxiliary door operation detection means is used as a condition for starting the dishwasher washing operation, that is, if the leftover filter is not cleaned, the next washing operation will not start even if the start button is pressed next time. It can also be. However, this is effective, but it forces forced cleaning of the leftover filter and may cause unnecessary trouble, so this should be an option.

  In addition, the auxiliary door that opens and closes the cleaning tank's leftover filter outlet is integrated with the front door unit, and the front door unit opens and closes so that the leftover filter outlet on the front wall of the cleaning tank can be opened and closed simultaneously. You can also. In this way, the open side of the leftover filter opening is opened simply by opening the front door unit, so that the opening and closing operation of the extraction opening is simple and convenient. In addition, when making such a structure, it is necessary to devise the sealing structure of the auxiliary door so that the leftover filter takeout port of the washing tank is securely sealed and the high sealing accuracy is maintained for a long time.

With regard to a drawer type dishwasher that puts and removes the leftover filter from the bottom opening of the tableware basket and the upper opening of the washing tank, by making it possible to put and remove the leftover filter from the front of the washing tank without pulling out the washing tank The leftover filter can be easily and easily cleaned, and after the cleaning operation is finished, the leftover filter cleaning lamp should be lit, and if the auxiliary door is not opened or closed, It is assumed that the leftover filter has been cleaned when the auxiliary door is opened and closed, and the leftover filter cleaning lamp is turned off when the auxiliary door is opened and closed. The vegetable filter will be cleaned.
Accordingly, the leftover filter is prevented from being left uncleaned.

Next, an embodiment will be described with reference to FIGS. Since the front door unit has a structure that opens and closes in the front-rear direction with the lower end as a fulcrum, there are advantages such as ease of use and hygiene, so this embodiment is configured to open and close the front door unit in the front-rear direction It is.
In this embodiment, the auxiliary door operation detecting means has the simplest mechanism and is easy to maintain.

[Example 1]
There are horizontal hinge pins 11, 11 at the front lower end of the front door 3 of the washing tub 2 of the drawer type dishwasher, and the hinge pins 11, 11 pivotally support the lower end of the front door unit 30. Thereby, the front door unit 30 is connected to the lower end of the cleaning tank 2 so as to be opened and closed in the front-rear direction.
There is a magnet locking piece 30m on the back surface of the upper end of the front door unit 30, which is attracted to the upper structure of the front door 3 of the cleaning tank 2 and locks the front door unit 30 in the closed position.

  In the vicinity of the front wall 25 of the washing tank 2, there is a leftover filter housing portion below the horizontal arm 8 a of the washing nozzle 8, in which the leftover filter 4 is housed, and a leftover filter outlet is provided. 10 is provided in the lower part of the front wall of the washing tank. There is a leftover filter at a position slightly lower than the leftover filter take-out port 10, so that a leftover filter removal operation, that is, a hand is inserted through the above-mentioned leftover filter take-out port 10, and a handle 4 a of the leftover filter 4. It is possible to easily carry out the operation of lifting it a little while holding it and removing it from the accommodating portion and pulling it out almost horizontally in that state.

The left side vegetable filter outlet 10 is a square opening having a width of 180 mm and a height of 130 mm. And the auxiliary door 20 which opens and closes this vegetable filter taking-out port 10 from the outer side of a washing tank is attached to the front wall lower part of a washing tank. There are horizontal hinge pins 21, 21 on the front wall 25 of the cleaning tank 2, and the lower part of the auxiliary door 20 is pivotally supported by the hinge pins 21, 21 so that the auxiliary door 20 is opened and closed in the front-rear direction. Two front walls 25 are connected.
A packing 20p is provided on the inner side surface of the auxiliary door 20, and abuts the peripheral vegetable filter outlet 10 periphery of the cleaning tank 2 to seal the contact portion between the auxiliary door 20 and the front wall 25 of the cleaning tank 2.

A leaf spring locking piece 22 is fixed to the outer surface of the front wall 25 of the cleaning tank 2 with a set screw 23, and the auxiliary door 20 is locked in the closed position by the leaf spring locking piece 22. The leaf spring locking piece 22 is made of spring steel having a thickness of 0.8 mm and a width of 50 mm, and has a locking portion 22a bent upwardly. The locking portion 22a has a V at the upper end of the auxiliary door 20. When the shape convex portion 20 a is fitted, the auxiliary door 20 is held in a state of being pressed against the outer surface of the cleaning tank 2 by the leaf spring locking pieces 22. A packing 20 p is attached to the back surface periphery of the auxiliary door 20, and is pressed against the front wall 25 of the cleaning tank 2, and the leftover filter take-out port 10 is sealed by the auxiliary door 20.
When the handle 20b at the upper front of the auxiliary door 20 is pulled with a finger, the V-shaped convex portion 20a is released from the locking piece against the elasticity of the leaf spring locking piece, and the auxiliary door 20 is opened.

  A door switch 40 is fixed to the lower front portion of the auxiliary door 20. This door switch 40 is turned on when pushed by the front door unit 30 when the auxiliary door 20 is closed and the front door unit 30 is further closed, and turned off when the front door unit 30 is opened.

  When a finger is pulled on the handle 31 at the upper front end of the front door unit 30 and the front door unit 30 is unlocked by the magnet locking pieces 30m, the front door unit 30 is opened to the front, and from the floor of the kitchen. Slightly above it becomes almost horizontal. If the front door unit 30 is opened and the auxiliary door 20 is opened, the leftover filter 4 can be taken out from the leftover filter outlet 10.

  When the cleaning operation is finished, the door switch 40 is closed at this time, so the leftover filter cleaning lamp 50 (see FIG. 1) is lit to urge the leftover filter 4 to be cleaned. When the front door unit 30 is opened, the door switch 40 is turned off, so that the leftover filter cleaning lamp 50 is turned off. This lamp display is a blinking display, and if the blinking is made intense as the lighting time elapses, the display effect due to the lighting becomes more remarkable. Further, as the lighting time elapses, the light emission intensity of the lamp may be gradually increased.

  In addition, a timer is interposed in the lighting drive circuit (not shown) of the leftover filter cleaning lamp 50, and when the cleaning operation is finished and the lamp 50 is turned on, 5 to 15 minutes (for example, 10 minutes) have passed. The lighting drive circuit is opened and turned off. When the leftover filter cleaning lamp goes off, the timer is reset.

  That is, as shown in FIG. 4, when the cleaning operation is completed (ST1), the leftover filter cleaning lamp is turned on (ST2). Thereafter, if the door switch 40 is turned off (ST3), the leftover filter cleaning lamp 50 is turned on. Is turned off (ST4). On the other hand, if the door switch 40 is not turned off (ST3), after 10 minutes (ST5), the leftover filter cleaning lamp is turned off (ST6).

In addition, when the display by the leftover filter cleaning lamp is changed to a voice display, it is preferable that the display sound is a melody sound and the melody sound can be selected from a large number. However, if that is done, the drive circuit of the display device becomes more complicated and more expensive than in the case of lamp display. Therefore, in the concrete design, the drive circuit for voice display is designed to be as simple and low-cost as possible. There is a need.
In addition, the warning display for prompting the cleaning of the leftover filter is sufficient for either the lamp display or the voice display, but if this is used together, the warning effect is more remarkable and reliable.

Although the case where the display for alerting is performed immediately after the cleaning operation has been described above, the same applies to the case where the display for alerting is performed at a predetermined time in the early morning (for example, 6 am). However, in this case, the first condition is that the lamp display is turned off after a predetermined time has elapsed since the end of operation, and then the second condition is that a predetermined time (for example, 6:00 am) has been reached. become. Under these two conditions, the leftover filter cleaning lamp lights up for a predetermined time (for example, 10 minutes). About this lighting, it may be made to blink and this may continue for 2 hours, for example, but it may be made to light for 10 minutes at intervals of 30 minutes, for example. And when 2 hours pass, it is good to make it stop with the signal from a timer.
Moreover, if a voice display is used together in the last one minute of the above 10-minute blinking lighting, the alerting effect is further enhanced.

The above is to clean the leftover filter immediately after the cleaning operation is completed, and to clean the leftover filter at the earliest possible time when the cleaning operation is not possible at night. Based on this idea.
However, for example, instead of quickly cleaning the leftover filter at the end of the cleaning operation, it may be desired that the cleaning be performed once a day during a calm time, not in the early morning. In order to respond to such a request, the operating time zone of the drive circuit for the display of the leftover filter cleaning lamp can be set appropriately, and the time zone should be set to suit individual users' wishes. do it. However, in this case, if the cleaning operation is not performed during the set time period, the leftover filter cleaning lamp 50 is not lit. Therefore, if the cleaning operation is performed before the set time period, the cleaning operation is performed during the set time period. Even if it is not, it is necessary to light up the leftover filter cleaning lamp at the end of the time period.

[Example of change]
In the first embodiment, as an auxiliary door operation detecting means for detecting the opening / closing operation of the auxiliary door 20, a door switch 40 is provided in the lower front portion of the auxiliary door 20, and the door switch 40 is turned ON / OFF by opening / closing the front door unit 30. Although it is turned off, the door switch 40 can be turned on / off by opening / closing the auxiliary door 20. In this case, for example, when a non-contact switch is provided on the front wall 25 of the cleaning tank 2 and a magnet is further provided on the auxiliary door, and the auxiliary door is closed and approaches the non-contact switch, the magnetic force of the magnet is increased. So that the switch can be opened.

Moreover, in Example 1, the front door unit 30 of the cleaning tank has an opening / closing door in the most part of the front surface of the cleaning tank, but only the portion overlapping with the auxiliary door 20 is an opening / closing door, and this is opened. Therefore, the auxiliary door 20 can be opened. In terms of cost, the structure having a full-face door as in the embodiment is advantageous, but the structure having a part of the door is advantageous in that the door is small and lightly operated.
In the first embodiment, the auxiliary door 20 may be configured to open and close in the left-right direction with the side edge as a support point, and there is no particular problem in terms of function and usability.

[Example 2]
Next, the auxiliary door that opens and closes the cleaning tank's leftover filter outlet is integrated with the front door unit, and the front door unit opens and closes so that the leftover filter outlet on the front wall of the cleaning tank can be opened and closed simultaneously. An example of the structure (Example 2) will be described with reference to FIG.
In the first embodiment, the auxiliary door 20 is opened and closed separately from the front door unit 30, whereas in the second embodiment, the auxiliary door 201 is integrated with the front door unit 301. Is different.
The auxiliary door 201 is fixed (or integrally formed) to the inner side surface of the front door unit 301, and a packing 201p is attached to the outer periphery thereof.

The front door unit 301 is opened and closed in the front-rear direction with the hinge pin 11 as an axis. When the front door unit 301 is closed, the auxiliary door 201 fits into the leftover filter takeout port of the front door 3 and seals it. When the front door unit 301 is opened, the auxiliary door 201 comes out of the leftover filter removing port of the front door 3, thereby opening the leftover filter removing port 10.
A door switch 401 is arranged on the front surface of the front door 3 and is turned on / off by opening / closing the front door unit 301.
According to the second embodiment, since the leftover filter extraction port 10 is opened simply by opening the front door unit 301, the opening and closing operation of the extraction port 10 is simple and convenient. However, the sealing by the packing 201p is performed for a long time. It is necessary to devise the sealing mechanism so that the resistance to the opening / closing operation of the front door unit 30 does not increase due to the sealing mechanism by the packing 201p. For that purpose, the leftover filter take-out port 10 may be a round hole, and the packing 201p may be a multi-lip seal made of a synthetic resin (for example, polyethylene terephthalate) having high wear resistance.
