Description

The present invention relates to a dishwasher.

Conventionally, this type of dishwasher has a configuration as shown in FIG. 10, in which an object to be washed such as tableware is stored in a washing tank, and an opening 2 provided in a main body 1 is provided with two doors 3a, 3b. After that, the washing pump injects washing water to perform the washing and rinsing steps of the object to be washed. The two doors 3a and 3b are configured to open and close the opening 2 of the washing tank by pivoting vertically to open and close the opening 2 with a simple configuration. The space required for the rotation of the door body is smaller than when the body is rotated and opened and closed, so that the installation of the apparatus is improved. Further, the length of the door body 3a projecting forward at the time of opening is reduced, so that the object to be cleaned can be easily taken in and out from the front (for example, see Patent Document 1).

However, in the above-mentioned dishwasher, the dividing position 4 between the doors is not particularly sealed, and the washing water may leak to the outside of the apparatus. A configuration in which the doors 3a and 3b are overlapped with each other has been considered (for example, see Patent Document 2).
JP-A-50-26356 JP-A-5-103743

However, in order to prevent water leakage, the two doors 3a and 3b are overlapped with each other. However, since the dividing positions 4 of the two doors 3a and 3b are free ends, it is easy to wash and warm water. There is a problem that a gap is easily generated due to thermal deformation, external pressure, or the like due to the use of, and sealing is difficult.

In addition, in order to completely seal by overlapping the doors 3a and 3b, it is necessary to lengthen the overlapping portion, and as a result, the length of one door increases. For this reason, the space required for the rotation of the doors 3a and 3b is increased, and the area required for installing the dishwasher is increased.

The present invention solves the above-mentioned problems, and aims to provide a compact and excellent installation property and to ensure a seal at the time of closing.

In order to solve the conventional problem, the present invention has an upper door body and a lower door body, and when closed, presses the upper door body with the lower door body to move the lower door body and the main body. It is configured to be locked by locking means.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited by the present embodiment.

(Embodiment 1)
1 and 2 are a side view and a sectional view of a dishwasher according to a first embodiment of the present invention. In the figure, there is a washing tank 5 provided in a main body 1, and an object 6 to be washed such as tableware is set in a washing basket 7 and stored in the washing tank 5. There are a water supply valve 8 for supplying cleaning water to the cleaning tank 5 and a cleaning pump 9 for pressurizing the cleaning water. A cleaning nozzle 10 for injecting the cleaning water is provided with a plurality of injection holes 11. The washing tank 5 has a filter 12 for collecting residual vegetables and a heating element 13 for heating, and has a temperature sensor 14 for detecting the temperature of the washing tank. Further, a drain pump 14a for discharging the cleaning water and a blower 15 for sending air to the cleaning tank 5 are provided. A blowing path 16 for guiding the air blown by the blower 15 to the cleaning tank 5 is provided, and the exhaust gas is discharged. An exhaust port 17 is provided in the door 18.

Further, two doors 18 (a lower door 19 and an upper door 20) for closing one opening 2 of the cleaning tank 5 are provided, and each of the doors 19, 20 is moved with respect to the main body 1. Support means 21 and 22 for movably supporting are provided. Further, at the dividing position 4 between the door bodies, a sealing member 23 made of an elastic body such as rubber is installed to seal the dividing position 4 in a watertight manner when the door 18 is closed, and the sealing member 23 is not exposed to the outside. (Protecting means) 24 and a guard member (guard means) 25 for preventing the jet for cleaning from directly hitting the sealing member 23.

Further, a locking means 26 for locking the door body 19 and the main body 1 at the closed position of the door body 18 is provided, so that the door body locking portion 27 is engaged with the main body locking portion 28. Further, a lock detecting means 29 such as a micro switch for detecting the locking of the locking means 26 is provided on the main body locking portion 28. The locking means 26 is configured to be locked simultaneously with the closing operation of the door 18. In addition, the opening and closing order of the doors is determined. When the door is opened, the lower door 19 and the upper door 20 are opened in this order, and when the door is closed, the upper door 20 and the lower door 19 are closed in the reverse order. Further, the lower door body 19 which is opened first is provided with a handle portion 30 for opening and closing the door and an unlocking means 31 for unlocking the locking means 26. Installed nearby.

Each of the support means 21 and 22 is provided with a torsion spring 32 as an urging means for urging the door body upward (not shown for the lower door body 19). In the opened state of 18, it can be pulled out forward.

Next, the operation and operation will be described. First, the basic operation of the dishwasher will be described. An object 6 such as tableware is set in a washing basket 7, stored in a washing tank 5, and a detergent is charged. 2 is closed and the operation of the apparatus is started. The cleaning step is performed in the order of a cleaning step of removing dirt from the article 6 to be washed, a rinsing step of flowing the attached detergent and garbage, and a drying step of drying water adhering to the article 6 to be washed. First, the water supply valve 8 operates to supply a predetermined amount of cleaning water to the cleaning tank 5, and then the cleaning pump 9 pressurizes the cleaning water and jets it from the cleaning nozzle 10. At this time, the heating element 13 such as a sheath heater provided in the cleaning tank 5 is energized, and the cleaning process is performed while heating the cleaning water. Further, the temperature sensor 14 detects the temperature of the cleaning tank 5, and when the temperature reaches a predetermined temperature or more, the power supply to the heating element 13 is stopped.

(4) After the completion of the cleaning process for a predetermined time, the cleaning water containing dirt is discharged out of the machine by the drain pump 14a, and fresh cleaning water is supplied. The cleaning pump 9 is operated, and the cleaning water is injected again from the cleaning nozzle 10 to rinse the object 6 to be cleaned to which the detergent, the residual vegetables, and the like have adhered. 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 step is continuously performed about three times. Finally, the washing water is discharged outside the machine, and the rinsing step is completed.

(4) Subsequently, a drying step is performed, and by operating the blower 15, outside air is blown into the cleaning tank 5 through the blowing path 16 and discharged from the exhaust port 17. At this time, the heating element 13 is energized, and the evaporation of water droplets adhered to the cleaning target 6 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.

The support means 21 and 22 are pivots for pivotally supporting the doors 19 and 20 in the vertical direction, and open the opening 2 as shown in FIG. Since one opening 2 is opened by the two doors 19 and 20, the opening 2 can be enlarged, and the object 6 to be cleaned can be easily taken in and out. Also, large tableware can be stored. Further, since the door body 18 is divided, the space required for the rotation of the door body is smaller and the installation area is smaller than in the case where the door body is rotated and opened by one door body.

シ ー ル Further, the seal member 23 is provided at the dividing position 4 of the plurality of doors 18 so that the divided surfaces can be reliably sealed and the length of the doors can be minimized. In the case of a single door, since the door body and the main body 1 are sealed, a reliable seal can be easily formed. Further, even in the case of a two-door structure, if the structure is a two-fold structure, the doors can be sealed relatively easily because they are pivotally supported. However, when the support member is used for each door body, the divided positions 4 of the door body 18 are free ends, and are easily bent by thermal deformation, pressing, or the like, so that reliable sealing becomes difficult.

Therefore, by using the sealing member 23 having elasticity capable of absorbing the deflection, the sealing property between the doors 19 and 20 can be reliably maintained and water leakage can be prevented. Further, it is not necessary to greatly overlap the doors, and the space required for the rotation of the doors can be made as small as possible. As a result, the ratio of installation in a small kitchen space in Japan is increased, and it is possible to solve the problem that the user wants to install the kitchen but cannot install it.

Since the installation area is small, it can be applied to many installation variations such as vertical installation and horizontal installation, and can be adapted to the form of each home. Further, the length of the door body 19 projecting forward in the opened state can be reduced, and the article 6 to be cleaned can be easily taken in and out. Note that a sealing means is also used between the main body 1 and the door 18.

In addition, since the support means 21 and 22 are provided for each of the doors 19 and 20, and each of the doors 19 and 20 is independently supported by the main body 1, there are cases where the doors are connected to each other. In comparison, the door 18 can be stably opened and closed, the operability is improved, and an easy-to-use device can be provided. In addition, the lengths and stop positions of the doors 19 and 20 can be individually adjusted, and the height of the apparatus can be arbitrarily set.

In addition, the protection member 24 is used to prevent the sealing member 23 from being exposed to the outside, so that a good appearance can be obtained, and the sealing member 23 is deteriorated such as high-temperature oil droplets scattered during cooking. To prevent deterioration or breakage. Further, the dividing surface 4 of the door body 18 is not easily fixed to the main body 1 and thus has a flexible structure. For example, when a foreign object is inserted into the dividing surface 4 from the outside due to mischief or the like, the seal becomes incomplete, and Leakage or high-temperature washing water can be prevented from flowing out of the apparatus. It should be noted that not being exposed does not mean completely obscuring the cover, but may be any condition in which it cannot be seen directly from the front or foreign matter such as chopsticks cannot be inserted.

Further, a guard means 25 for preventing the jet for cleaning from directly hitting the seal member 23 is used. If the jet of the cleaning water directly hits the place where the door body is deformed due to thermal expansion or the like during the washing, Although there is a high possibility of water leakage, the guard means 25 can prevent the jet stream from directly hitting the seal member 23, so that the sealing performance of the divided surface 4 of the flexible door 18 can be further improved. Although it is desirable that the jet can be completely shut off, an effect of improving the sealing property can be obtained even with a configuration in which a part of the jet is shut off.

Further, in the present embodiment, the opening and closing order of the door body is determined, and the upper door body 20 is opened after the lower door body 19 is opened at the time of opening. Further, since the seal member 23 is installed in a configuration adapted to the opening and closing order, and can be pressed in a substantially vertical direction with respect to the seal member 23, the seal member 23 can be reliably sealed with a small operating force without damaging the seal member 23. It is possible to do. Further, since the door body 19 that opens downward is first opened, water drops that fall with the opening of the upper door body 20 can be received, and the water drops that fall outside the apparatus can be prevented.

Further, if the rotation trajectory of the upper door body 20 does not protrude forward from the distal end position of the lower door body 19 as shown by the one-dot chain line in FIG. 2, it is possible to completely prevent water drops from falling outside the apparatus. . The shape of the main body 1 is such that the front surface is inclined rearward toward the top so that the trajectory of the distal end of the upper door body 20 fits in the rear. However, it is not limited to the shape. In addition, by forming the opening 2 on a part of the top surface or side surface of the main body 1, the opening 2 that is wider and easier to use can be obtained.

Further, in the present embodiment, the order of opening and closing the doors is restricted by the configuration of the door 18 and the seal member 23, but the order of opening and closing is 1) for the lower door 19 and 2) for the upper door 20. The description can be used for ordering. Further, providing the handle portion 30 only on the lower door body is one of the measures. Alternatively, the operability is improved by exposing the handle portion of the upper door body 20 after the lower door body 19 is opened, thereby further improving the usability.

The seal member 23 is sandwiched between the doors in the front-rear direction. However, a seal effect can be obtained with a structure in which the end surfaces of the doors 19 and 20 are sealed with each other.

Further, in the present embodiment, the lock means 26 for locking the door body 19 and the main body 1 at the closed position of the door body 18 is provided, and if the lower door body 19 is closed after the upper door body 20 is closed, The door locking portion 27 is configured to automatically engage with the main body locking portion 28. Further, since the lower door body 19 is configured to hold down the upper door body 20, it is possible to lock both the door bodies 19 and 20 only by locking the lower door body 19 and the main body 1. In addition, since the door body 18 and the main body 1 are locked, the locking operation can be performed smoothly without the main body 1 side escaping or bending when the lock is locked. Also, it is easy to maintain a watertight state between the door 18 and the main body 1.

ロ ッ ク Note that a lock means other than the lock means 26 may be used in combination, and a stronger locking state of the door body can be obtained.

The locking means 26 is configured to be locked simultaneously with the closing operation of the door body 19, so that the locking operation can be omitted. Since a plurality of doors 18 are provided, the operation of opening and closing the doors 18 is complicated, and it is important to reduce the number of operations even for one. Also, there is no fear of forgetting to lock and no risk of water leakage.

(5) If the lock state is detected by the lock detection means 29 and control is performed such that the cleaning pump is not operated when the lock state is not locked, a device that is less likely to cause water leakage can be provided.

Further, a handle portion 30 for opening and closing the door body is provided on the door body to be opened first, that is, the lower door body 19, and serves as a mark of the door body to be opened first and is easy to open. The mistake of opening from the door body can be prevented. Therefore, it is possible to prevent the door body 18 and the seal member 23 from being damaged by opening from another door body 20. After the lower door body 19 is opened, the upper door body 20 can be easily opened. Therefore, the handle portion 30 may or may not be provided. Can be opened and closed. In addition, if the operable configuration is such that the handle portion of the upper door body 20 is exposed after the lower door body 19 is opened, the clarification of the opening and closing order and the operability can be achieved.

Further, the door body to be opened first, that is, the lower door body 19 is provided with a lock releasing means 31 for releasing the locking of the locking means 26, and the opening operation of the door body 19 is performed after the locking means 26 is released. Therefore, the lead wire from the release of the lock to the opening of the door body can be shortened, and the opening operation of the door body 18 can be performed smoothly. In addition, it is possible to prevent the door 18 from being opened incorrectly. Moreover, by providing the unlocking means 31 near the handle portion 30, the unlocking means 26 and the operation of the handle portion 30 can be continuously performed with one hand, and the door body can be smoothly opened as one operation. Can be opened and closed. The vicinity is a distance that allows the unlocking means 31 and the handle 30 to be operated with one hand.

Further, since the torsion springs 32 provided as biasing means on the respective support means 21 and 22 bias the doors 19 and 20 upward, the opening / closing operation force of the doors 19 and 20 is reduced, and the operability is reduced. improves. Further, the impact force when the doors 19 and 20 freely descend by gravity can be reduced, and the stress applied to the device is reduced, which leads to improvement in durability and miniaturization of the device. Further, if the gravity of the doors 19 and 20 and the biasing force of the torsion spring 32 are balanced, the doors 19 and 20 can be stopped at an arbitrary place, and the doors 19 and 20 can be stopped depending on the height of the installation space. 18 can be adjusted. The above-described effect and comfortable operability can be obtained even if the upper door body 20 has a structure in which the torsion spring 32 acts so as to rise naturally in the middle of the rotation range.

FIGS. 1 and 2 show an example of a dishwasher having a table-top installation type and having an opening 2 on the front surface. However, the present invention is not limited to this, and may be a built-in dishwasher, or FIG. The same effect can be obtained even if the opening 2 is provided above as shown in FIG. In addition, although the surface including the long side in the rectangular shape of the horizontal cross section of the main body 1 is the opening 2, the short side may be the opening 2. Further, the door body 18 is divided into two parts and is configured to be opened and closed in the vertical direction. However, a structure divided into three or more parts is also conceivable. In addition, the same effect can be obtained by a configuration that rotates in the horizontal direction in addition to the vertical direction.

In addition, the support means 21 and 22 are the rotation fulcrum. However, the support means 21 and 22 may have a slide configuration, a configuration including two rotating links 33 and 34 as shown in FIG. 4, or any configuration. However, this configuration is not limited. 4 is provided with an interlocking means 35 for interlocking the opening and closing operations of the upper and lower doors 19, 20. If the handle 30 provided on the lower door 19 is opened when opened, both the doors 19 are opened. , 20 can be opened and closed by one operation. As a result, the usability of the apparatus is remarkably improved, and the opening / closing order of the door 18 can be uniquely restricted, so that the operator does not need to consider the opening / closing order of the door 18.

Note that the present invention relates to the opening / closing structure of the door body 18, and does not limit a cleaning or drying method or configuration, an operation mode, or the like. In the first embodiment, an example of the dishwasher / dryer having a drying function has been described. However, the door structure of the present invention can also be used in a dishwasher without a drying function, a dishdryer performing only drying, and the like. The same applies to other embodiments.

(Embodiment 2)
FIG. 5 is a sectional view of a door portion of a dishwasher according to a second embodiment of the present invention, and the same reference numerals are given to the same components as those in the first embodiment shown in FIG. As shown in FIG. 5, in the present embodiment, a locking means 26 for locking the door bodies 18 at the closed position of the door body 18 is provided, and the lower door body engaging portion 36 and the upper door body And a joint 37. Further, the unlocking means 31 for unlocking and the handle portion 30 are formed of the same member, and are provided on the lower door body 19.

Next, the operation and action will be described. If the lower door body 19 is closed after the upper door body 20 is closed, the lower door body engaging portion 36 urged by the spring 38 or the like fits into the upper door body engaging portion 37. By doing so, the upper and lower door bodies 19 and 20 are locked. Since each of the doors 19 and 20 is independently supported by the main body 1, the door 18 and the main body 1 can be locked by engaging the doors 19 and 20 with each other.

れ ば If locks are provided on each of the doors 19 and 20, two lock means are required. However, by locking the doors, both doors can be locked by one lock. Further, since the relative position between the doors 19 and 20 in the closed state of the door 18 is fixed by the locking means 26, there is no possibility that a gap is formed in the seal member 23, and the sealing can be reliably performed. .

The unlocking means 31 and the handle 30 are made of the same member, and the door 19 can be opened by one operation following the operation of unlocking.

(Embodiment 3)
FIG. 6 is a front view of a dishwasher according to a third embodiment of the present invention, in which the same components as those in the first embodiment shown in FIG. As shown in FIG. 6, in the present embodiment, a lock lever (lock means) 39 for locking the door 18 at the closed position of the door 18 is provided on the front surface of the door 19.

Next, the operation and function will be described. After the door 18 is closed, the lock lever 39 is moved in the left-right direction to lock the door 18. As shown in the figure, when the doors are locked at the center of the dividing position 4 of the door, since both are free ends, when a force is applied in the pushing direction, the door 18 is bent and locked. The force is not sufficiently transmitted to the means 39. Therefore, there is a possibility that a large force is required for the locking operation or the locking may be incomplete, which is not preferable. Therefore, the locking means 39 can be securely locked without difficulty by applying a force in the lateral direction to lock.

The operation of the lock lever 39 is not limited to the left-right direction, but may be the up-down direction. The same applies to a button type or the like instead of a lever type.

(Embodiment 4)
FIG. 7 is a schematic diagram of a kitchen apparatus according to Embodiment 4 of the present invention, in which the same components as those in Embodiment 1 shown in FIG. FIG. 7 shows a general kitchen apparatus, which is mainly composed of a sink 40 provided with a sink and a hanging cabinet 41 provided near the ceiling, and a drain shelf 42 and the like are provided below the hanging cabinet. . The tabletop dishwasher 43 is most convenient if it is installed on the worktop top surface 44 of the sink 40 as shown in the figure. Here, the dishwasher 43 is provided with a door stopping means 45 (not shown) that can stop the door 20 at a position where the maximum height of the door 20 including at least the main body 1 is 700 mm or less.

Assuming a general kitchen set, the height of the sink 40 to the top surface 44 is 850 mm, and the height to the upper part 46 of the hanging cabinet 41 is 2350 mm as standard. The height of the hanging cabinet 41 is 500, 700, 900 mm, and the like. When only the hanging cabinet 41 is installed above the sink, a 700-mm-high shelf is almost always installed. In this case, the distance between the sink top surface 44 and the lower part of the hanging cabinet 41 is about 800 mm.

In a multi-dwelling house or a kitchen set of a relatively small size, a drain cabinet 42 is often provided below the hanging cabinet 41 as shown in FIG. 7, and in general, a drain cabinet having a height of 500 mm and a hanging cabinet of about 300 mm is provided. The distance between the top surface 44 of the sink and the lower part 47 of the draining shelf is about 700 mm. Therefore, by setting the height when the door 18 is opened to 700 mm or less, the dishwasher can be installed in a general kitchen regardless of whether it is a single-family house or an apartment house. According to our survey results, if the height is 700 mm or less, it can be installed in about 75% of existing homes.

In recent years, devices having a reduced floor area of the apparatus main body and improved installability have become mainstream. In order to secure an internal capacity by reducing the floor area, the height of the main body 1 must be increased. There is a need to. In this case, since the height of the door body 18 is also increased, dividing the door body 18 into a plurality of pieces and shortening the same is very effective for improving the installation property. However, when the door body 18 is opened upward. If this is the case, the installation height will be high, and there is a possibility that installation is not possible due to the height limitation. Therefore, by dividing the door body 18 into a plurality of parts and setting the maximum height of the opening trajectory of the door body 18 including the main body 1 to 700 mm or less, a dishwasher that can be installed in any home can be provided.

Since the door body stopping means 45 can stop the door body 20 at least at a position of 700 mm or less, in addition to the improvement of the installation property as described above, the door body stopping means 45 can be installed at a plurality of places as shown in FIG. If there is room in the space above the apparatus, the door body 20 can be opened to the position A, and the inside of the cleaning tank 5 can be easily checked by opening the opening 2 more widely, and 6 can be easily taken in and out. Further, when the upper space is low, the opening 2 cannot be largely opened (position C), but can be installed and used sufficiently.

Although not specifically shown, the door body stopping means 45 may be configured to stop at any place by applying a frictional force, to stop at a balanced spring force, or to have a structure in which a latch is fitted at a plurality of locations. Various configurations are conceivable, such as a configuration in which the device is installed in any of the above.

In the present invention, the height is set to 700 mm or less. However, if the height is set to 650 mm or less, it is possible to cope with a case where the installation height of the hanging cabinet 41 is low due to a system having a height of 2300 mm, construction, or the like. Increased to accommodate most manufacturers' kitchens. In this case, according to our survey, it can be installed in about 85% of kitchens of existing houses.
