Description

The present invention relates to a dishwasher.

2. Description of the Related Art Conventionally, as shown in FIGS. 10 and 11, a dishwasher of this type is generally used. After being closed by the body 3, the washing pump injects washing water to perform the washing and rinsing steps of the object to be washed. The dishwasher shown in FIG. 10 has a configuration in which an opening 2 is provided on the front surface of the main body 1 and the door body 3 rotates downward to open the opening 2, and the dishwasher shown in FIG. , An opening 2 is provided on the upper surface, and the door 3 is turned upward to open. Further, the dishwasher shown in FIG. 12 has a configuration in which a door body is divided into two and opened and closed in a vertical direction (for example, see Patent Document 1).
JP-A-50-26356

However, in the conventional dishwasher shown in FIG. 10, since one door 3 is opened downward, the space required for the rotation of the door 3 is large, and the floor area of the main body 1 and the area of the door 3 are large. Therefore, there is a problem that the installation area for the total amount of the dishwasher is required, and the installability of the dishwasher is deteriorated. In addition, since the length of the front projection of the door body 3 is long, there is also a problem that it is difficult to take in and out the object to be cleaned from the front. On the other hand, in the dishwasher shown in FIG. 11, since it is opened upward, almost no installation area other than the main body size is required, but since the opening 2 is made large, the floor area of the main body itself becomes large. As a result, the installation property deteriorates. Further, since the opening is largely opened upward, the maximum height due to the opening and closing of the door is increased, and there are cases where the present apparatus cannot be installed due to the limitation of the height of the installation place.

In recent years, in order to improve installation in small kitchens in Japan, the equipment itself has been made smaller by increasing the floor area of the equipment itself, which has become the mainstream. Therefore, it is necessary to increase the height of the main body 1, and depending on the opening and closing method of the door body 3, there are many cases where the main body 1 cannot be installed due to the limitation of the height. That is, an object is to provide a device having a small installation area and a low height.

FIG. 12 shows an example of a structure corresponding to the opening and closing of a high-height door body. The length of each door body 3a, 3b is shortened, and the installation area and installation height are suppressed. Was to be able to do. Further, the door body 3b that opens upward rotates about the upper end of the door body 3b as a fulcrum, and the upward projection height increases regardless of the division of the door body. Because of the restrictions, there is a high possibility that it cannot be installed. Further, in order to lower the height at the time of opening, it is necessary to stop the door body 3b in a state of protruding forward from the top of the main body, and when the apparatus is installed on the top surface of the sink, the door at this opening position Since the body 3b is slightly below eye level, it is difficult to check the inside of the cleaning tank 2, and there is a problem that it is difficult to take in and out the object to be cleaned.

Despite the penetration rate of more than 50% in Europe and the United States, the low penetration rate of less than 10% in Japan is a major factor because the kitchen space is smaller than in Europe and the United States. Very often not possible. Therefore, in order to provide abundance to many consumers, it is necessary to provide a device that is a little compact and has excellent installability.

The present invention, in order to solve the above problems, a main body, a cleaning tank provided in the main body, an opening provided as a main surface of the front surface of the cleaning tank, a door that closes the opening, Supporting means for movably supporting the door body in the space above the main body.

The dishwasher of the present invention can reduce the height of the opening and closing trajectory of the door body, and can be installed in a place where the installation height on a worktop such as a system kitchen or a sink is limited. The length of the door body projecting forward in the opened state can be reduced, the inside of the cleaning tank can be easily checked, and the object to be cleaned can be easily taken in and out.

According to a first aspect of the present invention, there is provided a main body, a cleaning tank provided in the main body, an opening provided with a front surface of the cleaning tank as a main surface, a door closing the opening, and the door being the main body. And the supporting means for movably supporting the upper space of the door, the maximum height of the opening / closing trajectory of the door can be reduced in spite of the configuration in which the door is opened upward, and in the open state. The protruding length can be reduced in front of the door body. Tabletop dishwashers are often installed on worktops such as system kitchens and sinks.However, hanging cupboards and draining shelves are often installed above the space, which limits the height at which they can be installed. There is. In the dishwasher of the present invention, since the height required for installation can be reduced, the possibility that this dishwasher can be installed increases, and it is possible to answer the demand that installation is impossible even if it is desired. Also, since the length of the door body projecting forward in the opened state is small, it is possible to provide a device that makes it easy to check the inside of the cleaning tank and easily puts and removes an object to be cleaned.

A second invention provides a main body, a cleaning tank provided in the main body, an opening provided with a front surface of the cleaning tank as a main surface, a plurality of doors closing the opening, and the door And supporting means for movably supporting one of the doors in the space above the main body. By dividing the door, the length of one door is reduced. It is possible to further reduce the protruding length of the door body upward or forward due to the opening of the body, and to provide a device having higher installation properties. In addition, by opening the other door body downward, it is possible to prevent water drops and dirt from falling outside the apparatus.

According to the third aspect of the present invention, all the doors can be opened and closed by a single operation by providing the interlocking means for interlocking the opening and closing operations of the doors, and the usability of the apparatus is greatly improved. In addition, it is necessary to seal between the door bodies, but in order to perform the sealing securely, it is necessary to regulate the opening and closing order of the door bodies. It can be carried out.

According to a fourth aspect of the present invention, the support means has a structure in which the inner surface of the door body is not visible from the front in the process of opening and closing the door body, so that the inner surface of the door body to which water droplets, dirt, etc. adhere is exposed to the worker side. do not do. Since the door body is opened upward, it is located just near the worker's face at the time of opening. However, since the inner surface of the door body cannot be seen, it does not feel uncomfortable. Also, it is possible to prevent the clothes and the like from getting wet or dirty by contacting the door.

According to a fifth aspect of the present invention, the support means has a configuration in which the lower end of the door is always located below the upper end in the process of opening and closing the door. Can be prevented from dropping on the top surface.

According to a sixth aspect of the present invention, the support means includes a rotation fulcrum, and the rotation fulcrum is installed at a distance from the door, so that the door provided on the front surface has a very simple configuration of the rotation fulcrum, and is provided above the main body. Can be moved into space. Further, since only the rotation is performed, the opening and closing operation can be performed smoothly.

According to the seventh aspect, the rotation angle of the rotation fulcrum associated with opening and closing of the door body is set not to exceed 90 °, so that the inner surface of the door body can be prevented from being exposed to the front.

According to the eighth aspect of the present invention, since the supporting means includes the rotary link, the supporting means does not move on a simple arc trajectory, so that the degree of freedom of the trajectory increases. The door body can be opened upward after moving the door body forward, so that the door body is prevented from sliding on the sealing surface, and the sealing can be reliably performed with a small operating force. Also, wear and breakage of the seal member can be prevented. Further, the height, inclination, and the like of the door body in the opened state can be arbitrarily set.

According to a ninth aspect of the present invention, since the support means includes the slide portion, the door body can be moved in a direction away from the main body in an initial stage of the opening operation, regardless of any configuration such as a rotation fulcrum. And the body can be easily and reliably sealed. In addition, the entire opening / closing trajectory of the door body can be configured by a slide portion, and the opening / closing trajectory can be set freely.

According to the tenth aspect, the front surface of the main body has a shape in which the upper part is inclined rearward, so that the angle between the door body and the main body is larger than in the case of vertical, so that the door body is separated from the main body. In this case, a reliable and highly durable seal structure can be realized even when a simple rotation fulcrum is used.

According to an eleventh aspect of the present invention, the upper surface of the main body is formed to have a shape that cannot be mounted on the upper surface of the main body, such as being inclined in a plane, having a curved shape, or having irregularities, by being inclined. The article is prevented from being loaded on the upper surface of the main body by mistake, and the article is prevented from falling or dropping by opening the door body above the main body.

According to the twelfth aspect, the opening is provided with the front surface as a main surface and includes a part of the upper surface of the cleaning tank, so that the top portion of the main body can be easily sealed and the opening is widened. The inside of the cleaning tank is easy to see, and the object to be cleaned can be easily taken in and out.

According to the thirteenth invention, the tabletop dishwasher is often installed on a worktop such as a system kitchen or a sink by setting the maximum height of the opening locus of the door body including the main body to 700 mm or less. In many cases, a hanging cabinet, a drain cabinet, or the like is installed in the space above the space, and the installation height is limited. Therefore, if the maximum height of the opening locus of the door body is set to 700 mm or less, the dishwasher can be installed in a general kitchen. According to our survey results, if the height is 700 mm or less, it can be installed in about 75% of existing homes.

According to the fourteenth aspect, since the support means is installed inside the side wall of the main body, the support means is not exposed to the outside when the door is closed, so that a good appearance can be obtained. Further, even during the opening and closing operation, it is safe to operate the door while holding the hand on the main body.

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)
FIG. 1 is a side view of a dishwasher according to Embodiment 1 of the present invention, FIG. 2 is a sectional view of the same, and FIG. 3 is a schematic view of the kitchen apparatus.

1 and 2, there is a washing tank 5 provided in the main body 1, and an object 6 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.

Further, a door 18 for closing the opening 2 of the cleaning tank 5 is provided. As a support means 19 for movably supporting the door 18 in the space above the main body 1, a support arm 20 fixed to the door 18 is provided. A rotation fulcrum 21 is provided. The rotation fulcrum 21 is installed at a position distant from the door body 18, and the rotation angle associated with opening and closing is about 75 °. Further, the front surface of the main body 1 and the door body 18 have a shape in which the upper part is inclined rearward, and the maximum height of the opening trajectory of the door body 18 including the main body 1 is set to be 700 mm or less.

シ ー ル A seal member 22 is provided between the door 18 and the main body 1, and the seal member 22 is fixed to the main body 1. In addition, a handle portion 23 for performing a closing operation of the door body 18 is provided, and a lock means for locking the door body 18 and the main body 1 at a closed position of the door body 18 and a lock detecting means for detecting the locking of the lock means ( (Both are not shown), and a tension spring 24 is provided on the supporting means 19 as urging means for urging the door 18 upward. Further, the washing basket 7 can be pulled out forward with the door 18 in the opened state.

FIG. 3 shows a general kitchen apparatus, which is mainly composed of a sink 25 provided with a sink and a hanging cabinet 26 provided near the ceiling, and a drain shelf 27 and the like are provided below the hanging cabinet. ing. The table-top dishwasher 28 is most convenient when installed on the worktop top surface 29 of the sink 25 as shown in FIG. Here, in the dishwasher 28, the maximum height of the maximum trajectory of the door 18 including the main body 1 is 700 mm or less.

Next, the operation and action 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 and then stored in a washing tank 5 and a detergent is added. The opening 2 of the main body 1 is closed by the door 18 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 washing water to the washing tank 5, and then the washing pump 9 pressurizes the washing water and jets it from the washing 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 door 18 can be moved to the space above the main body 1 by installing the rotation fulcrum 21 at a position away from the door 18. When a rotation fulcrum is installed on the top 30 of the door body as shown in FIG. 1, in order to completely open the door body, the height of the main body 1 and the door body 18 as shown by A (two-dot chain line) is required. Space is required. Further, in order to reduce the height due to the opening, it is necessary to stop the door 18 in a state of protruding forward from the top of the main body 1 as shown in B. As shown in FIG. 3, the table-top dishwasher is used by being placed on the top surface of a sink or on a dedicated stand. In any case, the height at which the inside of the washing tank 5 is viewed obliquely from above the main body of the dishwasher. It is. Therefore, when the door 18 protrudes forward from the top of the main body, it is difficult to check the inside of the cleaning tank 5 and it is difficult to put the article 6 to be washed in and out.

In other words, installation and usability were in conflicting relations. Therefore, by moving the door 18 from the top 30 toward the space above the main body 1, the door 18 can be moved to the space above the main body 1 (solid line in FIG. 1) without standing upright from the main body 1. The maximum height of the opening / closing trajectory of the door 18 can be reduced, and the length of the door 18 projecting forward in the opened state can be reduced, so that both installation and operability can be achieved.

In order to cope with small kitchens in Japan, thin and tall type dishwashers have become mainstream, but in this shape, opening the front of the main body with opening 2 allows a larger opening to be obtained. Most advantageous. Then, by moving the 18 door body provided with the front opening 2 to the space above the main body 1, the floor area of the apparatus is small and the installation height can be small, so there is a possibility that the dishwasher can be installed. The price can be raised, and it is possible to answer the request that you can not install it even if you want to install it.

Also, as shown in FIG. 1, when one end of the door 18 is pivotally supported, one of the four sides to be sealed and one of the other three sides are sealed between the door 18 and the main body 1 as shown in FIG. The sides need to have different structures, and the sealing configuration is complicated for complete sealing. However, when all sides of the door 18 open and close apart from the main body as in the present embodiment, all sides can be uniformly sealed, and the configuration can be simplified.

Note that a configuration in which the door 18 is moved to the inside of the main body instead of above the main body 1 is also conceivable, but in that case, the height is increased by the amount of the cover, and the installation property is deteriorated.

In addition, the rotation angle of the rotation fulcrum 21 accompanying opening and closing of the door body 18 is set to about 75 ° and is suppressed to 90 ° or less. The inner surface 31 is not visible from the front. Since the door body 18 is opened above the main body 1, the door body 18 is located near the worker's face at the time of opening. However, since the inner surface 31 of the door body 18 cannot be seen, the user does not feel uncomfortable. In addition, it is possible to prevent dirt and the like from being attached by contact of the clothes and the like with the door body 18. When the front surface has a vertical shape, the inside of the door body is not visible from the front if the rotation angle is 90 ° or less, and the rotation angle is 90 ° or less when the front surface is inclined backward. There is a need.

The front surface of the main body 1 has an upper portion 32 inclined backward, and the angle between the door body 18 and the top surface of the main body 1 is 90 ° or more (about 120 ° in the figure). FIG. 4 is a schematic diagram. When the front surface is vertical as shown in FIG. 4A, the vicinity of the top of the door body 18 moves so as to slide in the lateral direction while contacting the sealing member. In the case where the door is inclined, as shown in FIG. 4B, there is no side slip, and the door moves in a direction away from the seal member 22.

(4) When the door body moves so as to slide on the seal member 22, the operation force is increased, and at the same time, the seal member 22 may be worn or damaged, which is not desirable. In addition, in order to eliminate the side slip, the opening / closing locus of the door body 18 becomes large. In addition, similar problems occur at the time of closing. Therefore, by inclining the upper front portion 32 of the main body backward, even when a simple rotation fulcrum 21 is used, it is possible to reliably seal with a small operating force and to realize a highly durable sealing structure.

In the case where the shape of the door 18 is a curved surface, the inclination angle is not clear, but it can be substituted by the tangent angle of the door top 30 or the angle connecting the upper and lower ends 33 and 34 of the door.

In addition, the door body 18 itself is inclined rearward. However, even if the door body 18 is vertical, the shape of the portion in contact with the door body 18 and the seal member 22 is inclined backward or has an arc shape. Also, the same effect can be obtained.

In addition, the lower end portion 33 of the inner surface of the door is always located below the upper end portion 34 in the entire opening / closing range of the door body 18, and the water droplets always gather downward, so that the water drops collect on the lower end portion 33 side. In addition, it is possible to prevent water drops and dirt from dropping on the top surface of the main body 1. Further, if the configuration is such that the water droplets on the door body 18 fall into the cleaning tank 5, it is possible to prevent the water droplets from falling out of the apparatus. Alternatively, by providing a configuration for receiving the water droplet only at the lower end portion 33 of the door body 18, the water droplet can be prevented from falling.

In addition, in this embodiment, the maximum height of the opening locus of the door body including the main body of the dishwasher is set to 700 mm or less, so that the present dishwasher can be installed in a general kitchen. Assuming a general kitchen set, as shown in FIG. 3, the height of the sink 25 to the top surface 29 is 850 mm, and the height to the upper part of the hanging cabinet 26 is 2350 mm. The height of the hanging cabinet 26 is 500, 700, 900 mm, and the like. When only the hanging cabinet 26 is installed above the sink, a 700-mm-high shelf is almost always installed. In this case, the distance between the sink top surface 29 and the lower part of the hanging cabinet 26 is about 800 mm.

In addition, in an apartment house or a kitchen set of a relatively small size, as shown in FIG. 3, there are many cases where a drain shelf 27 is provided at a lower portion of a hanging cabinet 26, and generally 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 29 of the sink and the lower part of the draining shelf 27 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.

The above effect can be obtained if the door 18 can be stopped at least at a position of 700 mm or less, such as when the door 18 can be stopped at a plurality of positions within the openable range.

Further, in the present invention, the maximum height of the opening trajectory of the door body 18 including the main body 1 is set to 700 mm or less. However, if the maximum height is set to 650 mm or less, the installation height of the hanging closet 26 is increased due to the convenience of a system having a height of 2300 mm or construction. It can be used even when the kitchen is low, increasing the possibility of installation, and can be used with kitchens of most manufacturers. In this case, according to our survey, it can be installed in about 85% of kitchens of existing houses. Furthermore, if the height is 600 mm or less, the dishwasher 43 can be installed even when the hanging cabinet 26 having a height of 900 mm is installed, and it can be installed in 95% or more of existing homes.

Although not particularly described, it is needless to say that the minimum value of the height is equal to or larger than the dimension of the main body 1.

Further, if the cleaning basket 7 is configured to be able to be pulled out forward with the door 18 being opened, the object 6 to be cleaned can be easily taken in and out of the interior of the cleaning basket 7 and the door 18 can be moved forward. Even if it is slightly protruding, the usability is not impaired.

(4) Since the tension spring 24 urges the door 18 upward, the weight of the door 18 is offset, the opening / closing operation force of the door 18 is reduced, and the operability is improved. Further, the impact force when the door body 18 freely descends due to gravity can be reduced, and the stress applied to the device is reduced, which leads to improvement in durability and downsizing of the device. If the urging force of the tension spring 24 of the door body 18 is balanced, the door body 18 can be stopped at an arbitrary place.

In this example, the number of the doors 18 is one, but it is divided into a plurality and the length of one door 18 is shortened, so that the installation property can be further improved. In addition, the support means is the rotation fulcrum 21, but the invention is not limited to this, and any structure may be used as long as it is capable of moving above the main body.

The present invention relates to an opening / closing structure of the door body 18, and does not limit a method and a configuration of cleaning and drying, an operation mode, and the like. In the embodiment, the example of the dishwasher / dryer having the drying function is shown. However, the dishwasher without the drying function, the dishdryer which only performs the drying, or other devices such as a storage device, the door of the present invention, Structures are available. The same applies to other embodiments.

(Embodiment 2)
FIG. 5 is a side view 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, the support means 19 including the rotation fulcrum 21 and the support arm 20 includes a slide portion 35 for moving the rotation fulcrum 21, and further includes a guide groove 36 and a guide portion 37 engaged therewith. It is installed on the main body 1 and the support arm 20. Further, the upper surface 38 of the main body has a shape inclined forward and backward.

Next, the operation and action will be described. When the door 18 is opened, first, the rotation fulcrum 21 slides from C to D by the slide portion 35 and then rotates to the point E. At this time, since the guide groove 36 and the guide portion 35 are engaged, the opening and closing operation is performed uniquely. In the initial stage of the opening operation, the door 18 moves in a direction substantially perpendicular to the main body 1 with the movement from C to D, so that the door 1 slides in the lateral direction while contacting the seal member 22. The sealing can be reliably performed with a small operation force, and high durability can be obtained. Similarly, even when the door 18 is closed, the sealing can be reliably performed with a small force. As shown in the figure, even if the front surface of the main body 1 is not inclined backward, the door 18 can be moved to the space above the main body 1.

In addition, since the door 18 passes through the space above the main body 1, if the door is opened while the article is mounted on the upper surface 38 of the main body 1, the article may drop. By inclining, it is possible to prevent an article from being erroneously placed and to prevent the article from falling or falling. In the drawing, the structure is inclined forward and backward.However, it is not possible to mount an article by inclining only forward or backward, or inclining left and right, or forming a curved surface, or providing unevenness. Any configuration may be used as long as it is unstable when mounted. It is also effective to specify the characters.

(Embodiment 3)
6 and 7 are a side view and a cross-sectional view of a dishwasher according to a third embodiment of the present invention. The same components as those in the first embodiment shown in FIG. 1 are denoted by the same reference numerals. As shown in FIG. 6, in the present embodiment, the door body is divided into two parts, a lower door body 39 and an upper door body 40, and two rotations are used as the support means 19 for supporting the upper door body 40 movably. An arm 41 is used. The support means for the lower door body 39 is a rotation fulcrum 42. Further, an interlocking means 43 for interlocking the opening and closing operations of the two lower door bodies 39 and the upper door body 40 is provided, and the handle portion 23 for opening and closing the door bodies is provided on the lower door body 39.

Next, the operation and the operation will be described. The rotating arm 41 supports the upper door body 40 so as to be openable and closable. However, unlike the case of using the rotation fulcrum, the movement trajectory is not a simple arc. The body 40 moves like a dashed line. Immediately after opening, the upper door body 40 moves from the main body 1 in a substantially vertical direction, then moves while turning upward, and finally moves to the state shown by the solid line in the figure. Since the upper door body 40 moves in a substantially vertical direction with respect to the seal member 22 provided between the upper door body 40 and the main body 1, the opening / closing operation force is small, and the seal member 22 is less likely to be worn or damaged. That is, by using the two rotating arms 41, the upper door body 40 can be moved above the main body 1 while realizing a reliable and highly durable sealing structure, and the same effect as in the first embodiment can be obtained.

The door body is divided into two parts, and the length of one door body is short, so that the length of the main body 1 projecting upward and forward is further reduced. In addition, since there is a margin in design, the sealing structure is more reliable. In addition, even if the upper door body 40 protrudes forward with one door body, it can be completely accommodated in the space above the main body 1 by dividing it into two or more parts. Is easier to see, and the object 6 to be cleaned can be easily taken in and out. Alternatively, when the upper door body 40 is not opened to the rear part of the upper surface of the main body, the rear part of the upper surface 32 can be used as a storage place.

Also, although the lower door body 39 is configured to rotate downward, since the length of the lower door body 39 is short, the installation area is small, and it is hard to hinder the installation. In addition, water drops and dirt falling from the upper door body 40, the drawn washing basket 7, and the like can be received, so that they can be prevented from falling out of the apparatus. In particular, if the opening / closing trajectory of the upper door body 40 is set to fall behind the tip of the lower door body 39 as shown in the figure, falling of water droplets or the like can be completely prevented. Further, when storing tableware and the like in the washing basket 7, it is possible to prevent the residual juice and the residual vegetables from dropping in front of the opening 2. That is, in the thin main body 1 having the front opening, the installability is high, the usability such as taking in and out is good, and it is possible to prevent water drops and dirt from falling out of the apparatus.

Further, as shown in FIG. 7, when the cleaning basket 7 is configured to be able to be pulled out forward with the door body opened, the object 6 to be cleaned can be easily inserted into and removed from the back of the cleaning basket 7. Since the washing basket 7 can be pulled out above the lower door body 39, water drops and dirt can be prevented from falling out of the apparatus when the washing basket 7 is pulled out.

Further, an interlocking means 43 for interlocking the opening / closing operation of the lower door body 39 and the upper door body 40 is provided, and when the lower door body 39 is opened by holding the handle portion 23 provided thereon, the lower door body 39 and the upper door body are opened. 40 can be opened and closed by one operation, and the usability of the device is dramatically improved. Further, since the interlocking means 43 can uniquely regulate the opening / closing order of the lower door body 39 and the upper door body 40, the interlocking means 43 opens first from the lower door body 39, and the tip thereof is always located forward of the upper door body 40. With such a setting, it is possible to reliably prevent water droplets and the like from dropping out of the apparatus.

In addition, the operator does not need to consider the order of opening and closing the doors. Specifically, a fulcrum 44 is provided at a position extending substantially linearly on the opposite side of the rotation fulcrum 42 of the lower door body 39, and the fulcrum 45 on the rotation arm 41 and the fulcrum 44 are connected by the interlocking means 43. Thus, the lower door body 39 can be configured to open first. Further, the support means 19 of the first embodiment can be similarly linked.

Also, since the interlocking means 43 has a link structure, the interlocking operation can be uniquely restricted both when the door is opened and when the door is closed, so that the interlocking operation can be reliably performed for any door operation. Further, even when the upper door body 40 is operated, the lower door body 39 moves in conjunction therewith, so that the door body to be operated does not matter. Note that the interlocking means 43 is not limited to the link structure, and similar effects can be obtained even if the interlocking means 43 has another configuration such as interlocking with a wire or interlocking with a gear, belt, chain or the like. Further, with the configuration shown in the figure, the connecting means 43 does not protrude outside the main body, and a good appearance can be obtained.

In FIG. 6, for easy understanding, the support means 19 such as the rotating arm 41 is shown as being installed on the side surface of the main body 1. However, as shown in FIG. Can be. In the closed state of the upper door body 40, since the support means 19 is not exposed to the outside, a good appearance is obtained.

In addition, the seal member 22 is disposed inside the support means 19 so that the support means 19 is completely sealed from the inside of the cleaning tank 5, and even if it is made of metal, rust and corrosion are prevented. And the durability is improved. Further, in order to secure the strength of the side wall 46 and reduce the width thereof, it is preferable that the members entering and exiting the main body be thin, and if the above-described configuration is such that the connecting means 43 does not protrude outside the main body 1, Since only the rotating arm 41 needs to enter and exit from the main body 1, it is possible to reduce the size in the width direction. The same can be said for the other embodiments.

In the present embodiment, the example in which the interlocking means 43 is provided is shown. However, even if the lower door body 39 and the upper door body 40 can be opened separately without using the interlocking means, the opening 2 Can be opened.

In addition, the inter-door seal member 50 is installed at the dividing position of the lower door body 39 and the upper door body 40, and the length of the door body can be minimized. Can be sealed. The divided position of the door body is a free end, and it becomes easy to bend due to thermal deformation, pressing, or the like, so that reliable sealing becomes difficult. However, by using the door-to-door seal member 50 having elasticity capable of absorbing this bending, the door body is reliably separated. In addition, the sealing property between the lower door body 39 and the upper door body 40 is maintained, and water leakage can be prevented.

Further, in the present embodiment, the opening and closing order of the lower door body 39 and the upper door body 40 is determined, and the upper door body 40 is opened after the lower door body 39 is opened at the time of opening. Since the door-to-door seal member 50 is installed and adapted to the opening / closing order and can be pressed in a substantially vertical direction with respect to the door-to-door seal member 50, the door-to-door seal member 50 is not damaged and small operation is performed. Sealing can be performed reliably with force. In addition, since the lower door body 39 that opens downward is opened first, water drops that fall with the opening of the upper door body 40 can be received, and it is possible to prevent water drops from falling outside the apparatus.

Although not shown, if the locking means for locking the lower door body 39, the upper door body 40, and the main body 1 at the closed position of the door body is provided near the divided position of the door body, The vicinity is a position where the movement distance associated with opening and closing is the largest, and the door body can be locked with the smallest force. Further, even when the lower door body 39 and the upper door body 40 are engaged with each other, the door body and the main body 1 can be locked.

Although the door is divided into two parts, one door 40 may be used, and the door may be rotated upward by the rotating arm 41. Further, although the example of the case of the table-top type with the front opening 2 is shown, the door body of the present invention can be applied to a built-in type or a case where the main opening 2 is provided above. it can.
