BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher mainly used for installation at home, such as a system kitchen or a dishwasher.

In the conventional dishwasher, as shown in FIG. 29 and FIG. 30, generally, to-be-cleaned objects, such as tableware, are accommodated in the washing tank in a main body, and the opening part 102 of the washing tank is closed by the door body 103 of the main body 101. FIG. Afterwards, the washing water was sprayed with the washing pump to perform the washing and rinsing process of the object to be washed. In FIG. 29, the opening 102 is formed in the front surface of the main body 101, and the door 103 is rotated downward to open the opening 102. In FIG. 30, the opening 102 is opened in the upper surface. ), And the door body 103 was configured to open by rotating upward.

However, in the conventional dishwasher shown in FIG. 29, since one door 103 is opened downward, the space required for the rotational movement of the door 103 is large, and the floor area and the door body of the main body 101 are large. The installation area of the sum total of the area | region of (103) was needed, and there existed a problem that the installation property of a dishwasher worsened. Moreover, since the protrusion length toward the front of the door body 103 is long, it also had a problem that it was difficult to put in and out the to-be-cleaned object from the front. On the other hand, in the dish washing machine of FIG. 30, since the door body 103 is opened upward, the installation area other than the main body size is hardly required, but since the opening 102 is large, the floor area of the main body 101 itself is increased. This increases, resulting in poor installability. In addition, since the door is largely opened upward, the maximum height due to the opening and closing of the door is increased, and the device (dishwasher device) cannot be installed due to the limitation of the height of the installation place.

In recent years, the dishwasher has become mainstream in order to increase the installability by reducing the floor area of the apparatus itself in order to improve the installability in a narrow kitchen in Japan. Therefore, since the height of the main body 101 must be made high as the floor area is reduced in order to secure the content amount, installation of the door body 103 in many cases cannot be provided due to the height limitation. In other words, it is a problem to provide a device having a small installation area and a low height.

Moreover, as what responded to opening and closing of a high height door body, there exist some which were described in Unexamined-Japanese-Patent No. 50-26356 as shown, for example in FIG. This structure divides the door 103 into two and opens and closes in the up-down direction. For this reason, the length of each door 103a, 103b was shortened, and the installation area and installation height were restrained low. However, since the door body 103b which opens upward is made to rotate as the upper end part of the door body 103b as a point, the height of protrusion upwards becomes large regardless of the division of the door body 103, and the installation height is restricted. The possibility of not being installed increases. In addition, in order to lower the height at the time of opening, it is necessary to stop the door 103b in the state which protruded forward from the upper part of the main body 101, and when this apparatus is installed in the ceiling surface of a mounting stand, The door body 103b is slightly below eye level. For this reason, there is a problem that it is difficult to check the inside of the washing tank, it is difficult to put in and out the object to be washed, and there is a risk of contacting the face or the head, which may lead to danger.

In addition, as shown in FIG. 32, there is an example in which the door body 103 has a structure in which two door bodies 103a and 103b are connected to each other and bent twice. In this case, the protruding length to the outside of the door body 103 becomes small, and the space required for opening and closing the door body 103 can be made small, so that the draining shelf or the like of the upper part does not interfere with the opening and closing of the door body 103. However, in the case of the dishwasher installed on the table, the installability of the apparatus was improved. In addition, since the two door bodies 103 are opened in one direction, the putting in and out of the tableware is not prevented.

However, while one door 103a is directly supported by the main body 101 in rotational motion, while the other door 103b is supported by the door 103a, the door 103a is the main body. Since it does not move uniquely with respect to (101), the opening and closing operation becomes unstable and has a problem that it is difficult to open and close. In addition, in order to operate uniquely, other regulatory means were required separately.

In addition, in the structure of FIG. 31 mentioned above, when two door bodies 103a and 103b are connected by the interlocking link 104, the other door body ( 103 operates uniquely. At this time, there is no problem as long as machining and assembly have been carried out to an ideal dimension, but in reality, there are always errors in parts due to machining and molding, assembly errors in assembling, and the like, which is not ideal. For this reason, even if the waterproofness in the case of opening / closing by the individual door bodies 103a and 103b alone is ensured, if a machining error, an assembly error, or the like exists in the part related to the interlocking link 104, it can be sealed. The doors 103a and 103b cannot be blocked at the correct position. In other words, even when the waterproofing of the doors 103a and 103b alone is secured, a plurality of doors are interlocked with each other so that a gap occurs during closing and water leaks during washing. If some water leaks are allowed, such as for business purposes, there is no problem. However, water leaks should not occur because kitchen counters and floors are flooded at home. In addition, if the processing or assembly error of the parts related to the interlocking device of each door is large, the occlusion operation may become heavy or impossible.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a first object of the present invention is to realize an opening and closing method of a door body by improving the installation property by suppressing the height required for the installation of the dishwasher to a low level and not impairing the convenience of use. do.

Moreover, a 2nd object is to provide the dishwasher which can open a some door body to one direction of an opening part by stable operation, and is easy to install.

Further, a third object is to prevent leakage by closing the door body in a correct position that can be sealed with the dishwasher main body even when a machining error or an assembly error of a component exists.

In order to achieve the first object, the dishwasher of the present invention includes a dishwasher main body (hereinafter referred to as a main body), a washing tank provided in the main body, an opening formed by forming the front surface of the washing tank as a main surface, The door body which opens and closes the said opening part is provided, and the support means which supports the said door body so that a movement to an upper space of the said main body is provided and comprised. As a result, when the door is opened, the door can be moved to the upper space of the main body so as to follow the upper part of the main body. Therefore, even though the door body is opened upward, The maximum height can be made low, and the protruding length of the door body in the open state can be made small. In addition, since the protruding length toward the front of the door body in the open state is also small, it is possible to provide an apparatus which is easy to check the inside of the washing tank and easily puts in and out the object to be cleaned.                         

In addition, the present invention is preferably configured to include a plurality of door bodies, and supporting means for movably supporting one of the door bodies to an upper space of the main body. Since the length of one door can be shortened by dividing, the protruding length of the door can be further reduced according to the opening of the door, or the front of the door can be further reduced. By opening the other door downward, it is possible to prevent the water droplets and dirt from falling out of the washing machine.

Next, in order to achieve the second object, the dishwashing machine of the present invention has a main body, a plurality of door bodies for closing the washing tank and the opening of the washing tank, and a support means for supporting the door body to be movable relative to the main body. It is provided corresponding to each door body, and the said support means is set as the structure which opens all the door bodies to the one direction side of an opening part.

Since the supporting means for supporting the door body divided into a plurality is configured to open all the doors to one side of the opening, opening the doors in a direction that does not interfere with the removal of the object to be cleaned does not impair the convenience of use. Do not. Moreover, if it is set as the structure which closes the other door body after closing one door body, it is not necessary to carry out all sealing simultaneously, and sealing can be performed easily and reliably.

Further, the present invention is preferably such that all the supporting means is configured to support the rotational movement of the door body, and the door body is operated uniquely with respect to the main body, thereby further improving the opening and closing operation of the door body.                         

Next, in order to achieve the third object, the dishwasher of the present invention includes an interlocking means for interlocking an opening / closing operation of the main body, a plurality of door bodies that close the opening of the washing tank and the washing tank, and the door. The area | region which does not cooperate with the area | region which cooperates with the opening / closing operation | movement of the said door body is formed in the opening / closing range of the sieve.

By having an area which interlocks a plurality of door bodies, opening one door can also open another door, so that the opening can be opened and closed by one opening and closing operation. In addition, since there are regions in which the doors do not interlock, the doors can be sealed independently in the closed position, so that the doors can be sealed independently in the closed position. Since it is possible to block at the correct position, water leakage can be reliably prevented even when the door body is interlocked if waterproofing at the time of individual door body opening and closing is ensured. In addition, when the door body is opened and the door body is not interlocked, part of the door body can be opened after opening, and the opening of the washing tank can be opened more widely. Can be easily executed.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described with reference to drawings.

(Example 1)

In addition, the bottom of the washing tank (5) is provided with a temperature sensor (14) for detecting the temperature of the washing tank (5), a drain pump (14a) for discharging the washing water, and a blower (15) for sending air to the washing tank (5). The blower path 16 which guides the air blown by the blower 15 to the washing tank 5 is provided, and the exhaust of the washing tank 5 is discharged | emitted to the exhaust port 17. FIG.

Moreover, the door body 18 which closes the opening part 2 of the washing tank 5 is provided in the front surface of the main body 1, and the door body 18 turns into the space above the main body 1, and the door body 18 It is supported by the support means 19 which consists of the support arm 20 fixed to the support arm 20, and the axis | shaft 21 provided in the main body 1, The door 18 is opened from the top part 30 at the time of opening. It is set as the structure which moves to the space above the main body 1. As shown in FIG. The spindle 21 is provided at a position away from the door 18, and the rotational angle of the door 18 in opening and closing is about 75 degrees. In addition, the front surface of the main body 1 and the door body 18 are the shape in which the upper part inclined rearward, and the maximum height of the opening trace of the door body 18 containing the main body 1 is set to 700 mm or less. Doing.

Moreover, the sealing member 22 is arrange | positioned between the door body 18 and the main body 1, and the sealing member 22 is being fixed to the main body 1 side. In addition, the door body 18 is provided with a handle portion 23 for executing this opening and closing operation, and the locking means and the locking means for locking the door body 18 and the main body 1 at the closed position of the door body 18. Locking detecting means (not shown) for detecting the lock is provided, and pressing means such as a coil spring for pressing the door 18 upward on the support arm 20 of the supporting means 19 (tension, for example). Spring 24 is provided. In addition, the washing basket 7 can be pulled out in the front in the open state of the door 18.

3 is a schematic view of a general kitchen apparatus, the kitchen apparatus is mainly composed of a dishwasher 25 with a sink and the upper cupboard 26 installed near the ceiling, the lower shelf of the upper cupboard 27, etc. Is installed. And, the table-type dishwasher 28 of the above configuration is most convenient when installed on the work table (ceiling surface) 29 of the dishwasher 25 as shown in FIG. Here, the dishwasher 28 makes the maximum height of the largest trace of the door 18 containing the main body 1 into 700 mm or less as mentioned above.

Next, the operation and operation of the above-described configuration will be described. First, the basic operation of the dish washing machine will be described. The to-be-washed matters 6, such as tableware, are set in the washing basket 7 and stored in the washing tank 5, and after the detergent is added, the opening 2 is closed by the door 18 and the dishwasher device (hereinafter, Operation of the device). The operation is performed in the order of a washing step for removing dirt from the to-be-washed material 6, a rinsing step for washing off the attached detergent or residue, and a drying step for drying the water attached to the to-be-washed object 6. 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 sprays it from the washing nozzle 10. At this time, it is energized by heat generating elements 13 such as a sheath heater installed in the washing tank 5, and the washing process is performed while heating the washing water. Moreover, since the temperature sensor 14 detects the temperature of the washing tank 5, when the temperature is over the predetermined temperature, the electricity supply to the heat generating element 13 is stopped.

After the predetermined time washing process, the washing water including the dirt is discharged out of the apparatus by the drain pump 14a and the washing water is newly supplied. By operating the washing pump 9, the washing water is sprayed again from the washing nozzle 10 to rinse the to-be-cleaned object 6 to which a detergent, a residue, etc. are attached. After the operation for a predetermined time, the operation of discharging the washing water and supplying the washing water again is repeated, and this rinsing process is performed about three times continuously. Finally, the wash water is discharged out of the device and the rinsing process is terminated.

Subsequently, a drying process is performed to operate the blower 15, whereby the outside air is blown into the washing tank 5 through the blower path 16 and discharged from the exhaust port 17. At this time, the heat generating element 13 is energized, and the evaporation of the water adhered to the to-be-cleaned object 6 is accelerated by the effect of both blowing and temperature. Their drying process is carried out for a predetermined time and the operation is terminated.

In addition, the door body 18 moves the door body 18 to the upper space of the main body 1 by providing the pivot 21 in the position away from the door body 18. As shown in FIG. When the shaft is installed on the top 30 of the door 18 as shown in FIG. 1, the main body 1 and the door 18 are opened as in A (two dashed lines) to completely open the door 18. You will need as much space as the sum of the heights. In addition, in order to lower the height according to the opening, it is necessary to stop the door 18 in the state which protruded forward from the upper part 32 of the main body 1 like B. FIG. As shown in FIG. 3, the table-type dishwasher 28 is used on the ceiling surface 29 or the exclusive stand of the dishwasher 25, but in any case, it is inclined from the inclined upper side of the dishwasher main body 1. It is the height to see inside the washing tank (5). Therefore, in the state where the door body 18 protrudes forward from the upper part 32 of the main body 1, it is difficult to confirm the inside of the washing tank 5, and it becomes difficult to put in and out the to-be-washed material 6. In addition, a face or a head may come into contact with the protruding door 18, which may lead to danger or damage to the apparatus.

That is, in the conventional one, the installation property and the convenience of use were in conflict. Therefore, the door body 18 moves from the top part 30 toward the upper space of the main body 1 along the upper surface of the main body 1 so that the door body 18 is not erected from the main body 1 without being erected from the main body 1. Since it can move to the upper space (solid line of FIG. 1) of 1), the maximum height of the opening / closing trajectory of the door body 18 can be made low, and the protrusion to the front of the door body 18 in an open state is carried out. The length can be made small, and both installation and operability can be achieved.

In order to cope with the narrow kitchen in Japan, a thin and tall dishwasher has become the mainstream in recent years, and this shape is most advantageous because a large opening can be obtained by opening the front of the main body with the opening 2. . The bottom area of the apparatus can be reduced and the installation height can also be lowered by moving the door 18 provided in the opening 2 on the front surface of the main body 1 to the upper space of the main body 1. The possibility of being able to install a dish washer increases, and it can answer the request not to install even if it wants to install conventionally.

In addition, if the sealing between the door 18 and the main body 1 is axially supporting the one end side (normal part 30) of the door 18 like FIG. 1, the shaft part of four sides to seal will be sealed. Since one side and the other three sides need to have different structures, the sealing structure is complicated to completely seal. However, when all sides of the door 18 are opened and closed away from the main body 1 as in the present embodiment, all sides can be uniquely sealed and the configuration can be simplified.

In addition, although the structure which moves the door 18 to the inside of a main body rather than the upper part of the main body 1 is also considered, in that case, the height of the cover part becomes high and installation property deteriorates.

In addition, since the rotation angle of the shaft 21 according to the opening and closing of the door body 18 is about 75 ° and is suppressed to 90 ° or less, the door to which water droplets or dirt are attached during the opening and closing process of the door body 18. The inner surface 31 of the sieve 18 is not seen from the front. Since the door 18 is opened to the upper space of the main body 1, the door 18 is positioned near the face of the worker at the time of opening, but the inner surface 31 of the door 18 is not visible. I do not feel unpleasant. In addition, when clothing or the like comes into contact with the door body 18, dirt and the like can be prevented from adhering. In addition, when the front surface of the main body 1 is vertical, when the rotation angle is 90 degrees or less, the inside of the door body is not seen from the front, and when the upper front surface of the main body 1 is inclined backward (90 °) Since the inner surface 31 is not exposed in the case of)-(tilt angle), the rotation angle needs to be 90 ° or less.

In addition, the front surface of the main body 1 is a shape in which the upper part 32 was inclined backward, and the angle of the door body 18 and the upper surface of the main body 1 is 90 degrees or more (about 120 degrees in FIG. 4B). ) 4 shows a schematic view of the sealing portion of the front surface of the main body. When the front surface is vertical as shown in FIG. 4A, the vicinity of the top of the door 18 moves in a horizontal direction while contacting the sealing member, but the front surface is inclined. If there is, there is no slipping sideways as shown in Fig. 4B, and the door moves in a direction away from the sealing member 22. When the door body moves as if the sealing member 22 is slid, the operation force increases and there is a possibility that the sealing member 22 may be worn or broken, which is not preferable. In addition, the opening and closing trajectory of the door 18 becomes large in order to remove slippery to the side. The same problem also occurs when occlusion. For this reason, even when the simple axis | shaft 21 is used by inclining the front upper part 32 of a main body backward, it can reliably seal with a small operation force and it can realize the durable sealing structure.

In addition, when the shape of the door 18 is a curved surface, the inclination angle is not clear, but the tangential angle of the top 30 of the door 18 or the upper end 34 and the lower end 33 of the door 18. It can be substituted by the angle to connect.

In addition, although the door body 18 itself was made to incline backward, the door body 18 is vertical, or the shape of the part which contact | connects the door body 18 and the sealing member 22 is inclined backward, or a circular arc. Even in the shape, the same effect can be obtained.

In addition, in the entire opening and closing range of the door 18, the lower end 33 of the inner surface of the door is always positioned below the upper end 34, and since the water droplets always collect downward, the lower end 33 The water droplets and the dirt can be prevented from falling on the ceiling surface of the main body 1. In addition, when the water droplet of the door body 18 is made to fall into the washing tank 5, it can also prevent that a water droplet falls out of an apparatus. Alternatively, the drop of the water drop can be prevented by providing the constitution which receives the water drop only on the lower end portion 33 of the door 18.

In the present embodiment, the maximum height of the opening trajectory of the door 18 including the dishwasher main body 1 is 700 mm or less, so that the dishwasher can be installed in a general kitchen. Assuming that it is a general kitchen set, the height to the ceiling surface 29 of the dishwasher 25 is 850 mm and the height to the top of the upper cupboard 26 is 2350 mm as shown in FIG. 3. The height of the upper side cabinet 26 is 500, 700, 900 mm, etc., and when only the upper side cabinet 26 is installed above a sink, it is common to install the shelf of height 700 mm. In this case, the distance between the ceiling surface 29 and the lower part of the upper cabinet 26 is about 800 mm. In addition, in a multi-family house or a kitchen set of a relatively small size, as shown in FIG. 3, a draining shelf 27 is often installed in the lower part of the upper cupboard 26, and generally, about 300 mm in the upper cupboard having a height of 500 mm. There is a drainage shelf, and the distance between the ceiling surface 29 and the lower part of the drainage shelf 27 becomes about 700 mm. Therefore, by setting the height at the time of opening of the door 18 to 700 mm or less, this dishwasher can be provided if it is a general kitchen regardless of a single house or a collective house. In addition, according to the results of our survey, installation is possible in about 75% of existing homes if the height is 700 mm or less.

Moreover, the said effect can be acquired if it can stop at the position of at least 700 mm in height, such as when the door body 18 can be stopped at the several place within the openable range.

In the present invention, the maximum height of the opening trajectory of the door body 18 including the main body 1 is 700 mm or less. However, when 650 mm or less is used, the upper side cupboard may be used depending on circumstances such as a system or construction having a height of 2300 mm. Even if the installation height of (26) is low, it can cope, and the installation possibility rate increases and can respond to the kitchen of most manufacturers. In this case, our survey will allow the kitchen to be installed in approximately 85% of existing homes. Moreover, if the height is 600 mm or less, even when the upper side cabinet 26 of 900 mm height is installed, the dishwasher 28 can be installed and it can be installed in 95% or more of existing homes.

In addition, although not mentioned separately, it cannot be overemphasized that the value of the minimum side of a height is more than the dimension of the main body 1. As shown in FIG.

In addition, if the washing basket 7 is configured to be taken out in the open state of the door 18, the washing basket 7 can be easily taken in and out of the laundry 6 into the washing basket 7. Even if the door body 18 slightly protrudes forward, the usability is not impaired.

Since the tension spring 24 presses the door 18 upward, the weight of the door 18 is canceled, and the opening / closing operation force of the door 18 becomes small and the operability improves. In addition, the impact force when the door body 18 falls freely due to gravity can be reduced, and the stress applied to the device is reduced, leading to improved durability and miniaturization of the device. Moreover, if the gravity of the door 18 and the pressing force by the tension spring 24 are balanced, it is also possible to stop the door 18 at arbitrary places.

In addition, in this example, although the door body 18 was made into one, the installation property can be improved further by dividing into several and shortening the length of one door body 18. As shown in FIG. In addition, although the support means 19 was made into the rotational movement point by the spindle 21, it is not limited to this, It is good as long as it is a structure which can move to the space above the main body.

Moreover, this invention relates to the opening-closing structure of the door 18, and does not limit a washing | cleaning or a drying method, a structure, an operation mode, etc. Although an example of a dish washing dryer having a drying function is shown in the present embodiment, the door structure of the present invention can be used for other equipment such as a dish washing machine without a drying function, a dish dryer for performing only drying, or a storage device. .

(Example 2)

FIG. 5 is a side view of the dish washing machine according to the second embodiment of the present invention, in which the same components as those in the first embodiment shown in FIG.

As shown in FIG. 5, the support means 19 including the axis 21 and the support arm 20 are provided with a slide portion 35 for moving the axis 21 and the guide groove 36. In the main body 1, a guide portion 37 coupled to the support arm 20 is provided. In addition, the upper surface 38 of the main body 1 has a shape inclined back and forth.

The operation and action will be described. First, when opening the door 18, the pivot 21 slides from C to D by the slide unit 35, and then rotates to E point. At this time, since the guide groove 36 and the guide portion 37 are coupled, the opening and closing operation is performed uniquely. In addition, in the initial stage of the opening operation, as the door body 18 moves in a substantially vertical direction with respect to the main body 1 as the door moves from C to D, the door body 18 is in contact with the sealing member 22. It can be reliably sealed with a small operating force without slipping in the lateral direction while providing high durability. In addition, when the door body 18 is closed, similarly, it can be reliably sealed with a small force. Even when the front surface of the main body 1 is not inclined backward as in FIG. 5, the door body 18 can be moved from the top portion 30 of the door body 18 to the space above the main body 1.

In addition, since the door 18 passes through the upper space of the main body 1, if the door is opened with the article mounted on the upper surface 38 of the main body 1, there is a possibility that the article may fall. By inclining the upper surface 38 of the main body, accidental loading of the article is prevented, and fall or fall of the article is prevented. In addition, in Fig. 5, the configuration is inclined back and forth, but it is impossible to mount the article such as inclining only forward or backward, inclining in the left-right direction, making a curved surface, or providing irregularities, or instability when mounted. It may be a configuration that is reduced. It is also effective to specify in letters.

(Example 3)

6 and 7 are side views and cross-sectional views of the dish washing machine according to the third embodiment of the present invention. The same components as those in the first embodiment shown in FIGS. 1 and 2 are denoted by the same reference numerals, and description thereof will be omitted.

As shown in Fig. 6, in the present embodiment, the door body is divided into two, the lower door body 39 and the upper door body 40, and the support means 19 for movably supporting the upper door body 40. ), Two rotary arms 41 are used. In addition, the support means of the lower door body 39 is the spindle 42. Further, an interlocking means (interlocking link) 43 for interlocking the opening and closing operations of the two upper and lower door bodies 40 and 39 is provided, and the handle portion 23 for opening and closing the door body is provided with a lower door body ( 39).

Next, the operation and the operation will be described. The rotary arm 41 supports the upper door 40 so as to be openable and close, but unlike the case of the axis 21 in Embodiment 1, the upper door 40 ) Is not a simple arc, and in the configuration shown in Fig. 6, the upper door body 40 moves like a dashed line. Immediately after the door 40 is opened, the door 40 moves in a substantially vertical direction from the main body 1, and then moves upward as it follows the upper surface of the main body 1 while turning upwards. Go to the state of. Since the door body 40 moves in a substantially vertical direction with respect to the sealing member 22 provided between the upper door body 40 and the main body 1, the opening and closing operation force is small, and the sealing member 22 is worn out. It is difficult to cause breakage. That is, by using the two rotary arms 41, the upper door body 40 can be moved above the main body 1 while achieving a reliable and durable sealing structure, and the same effect as in the first embodiment can be obtained. .

In addition, since the door body is divided into two and the length of one door body is short, the protruding length toward the front and the front of the main body 1 is further reduced. Moreover, since a clearance is also provided by design, a sealing structure becomes more reliable. In addition, in one door body, the upper door body 40 can be completely stored in the upper space of the main body 1 by at least two divisions even when protruding forward, so that the inside of the washing tank 5 can be seen better. In and out of the washings 6 can be easily performed. Alternatively, when the door body 40 is not opened to the rear portion of the upper surface of the main body, the rear portion of the upper surface 38 can be used as a storage place.

In addition, although the lower door body 39 is a structure which rotates downward, since the length of the lower door body 39 is short, the installation area may be small and it does not interfere with installation. In addition, water droplets and dirt falling from the upper door body 40 and the drawn out washing basket 7 can be received, and the water droplets and dirt can be prevented from falling out of the apparatus. In particular, as shown in FIG. 6, if the opening / closing trajectory of the upper door body 40 is settled from the rear of the lower door body 39, falling of water droplets and the like can be completely prevented. In addition, when storing dishes etc. in the washing | cleaning basket 7, it can also prevent that the remaining soup and remnants fall to the front of the opening part 2. That is, in the main body 1 having a thin front surface opening, the installation property is high, the use of putting in and out is convenient, and it is possible to prevent the drop of water and dirt out of the apparatus.

In addition, as shown in FIG. 7, when the washing basket 7 is configured to be pulled forward in the open state of the door, the washing basket 7 can be easily carried out and taken out of the object to be cleaned 6 into the washing basket 7. Since the washing basket 7 can be pulled out above the lower door 39, it is possible to prevent water droplets and dirt from falling out of the apparatus when the washing basket 7 is taken out.

In addition, the lower door body 39 and the upper door body 40 are provided with interlocking means (linking device) 43 for interlocking these opening and closing operations, and the handle portion 23 provided in the lower door body 39. ), Both doors 39 and 40 can be opened and closed in one operation, which greatly improves the usability of the device. In addition, since the interlocking means 43 can regulate the opening / closing order of the upper and lower door bodies 40 and 39 in a unique manner (one operation), the interlocking means 43 is opened first from the lower door body 39, and the front end portion thereof is opened first. By setting the front side at all times, the water droplets can reliably be prevented from falling out of the apparatus. In addition, the operator does not need to consider the opening and closing order of both doors. Specifically, the point 44 is provided in the position which extended substantially linearly on the opposite side to the axis 42 of the lower door body 39, and the point 45 on the rotating arm 41 and the said point ( By connecting 44 to the interlocking means 43, the lower door 39 can be configured to open first. In addition, even the support means 19 of Example 1 can be interlocked similarly.

In addition, since the interlocking means 43 has a link structure, the interlocking operation can be uniquely regulated both at the time of opening and at the time of closing, so that the interlocking opening / closing 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 with each other, so that any door body may be operated. In addition, the interlocking means 43 is not limited to the link structure, and the same effect can be obtained even with other configurations, such as connecting with a wire or interlocking with a cog wheel, a belt, a chain, or the like.

In addition, with the structure shown in FIG. 6, the interlocking means 43 does not come out of the main body 1, and there is no possibility that a risk of pinching or the like between the linkages 43 may occur, and satisfactory. Appearance can be obtained.

In addition, in FIG. 6, although the support means 19, such as the rotation arm 41, were shown so that it may be provided in the side surface of the main body 1, as shown in FIG. 8, the side wall 46 of the main body 1 is shown. ) Can be stored inside. In the closed state of the upper door body 40, since the support means 19 are not exposed to the outside, a good appearance can be obtained and there is no fear that a finger or the like will be caught at the start.

In addition, even if the upper door body 40 is operated by touching the main body 1 during the opening and closing operation, there is no danger of pinching the fingers as described above. Moreover, as shown in FIG. 8, the sealing member 22 is provided in the inner part rather than the rotating arm 41 which is the support means 19, and the rotating arm 41 is completely sealed with the inside of the washing tank 5. As shown in FIG. Even if the support means 19 (rotary arm 41) is made of metal, durability can be improved, such as being able to prevent rust and corrosion. In addition, in order to ensure the strength of the side wall 46 and to reduce the width, the member entering and exiting from the main body 1 is preferably thin, and if the interlocking means 43 is the above-described configuration that does not come out of the main body 1. Since only the rotation arm 41 is sufficient for the member which enters and exits from the main body 1, it leads to miniaturization of the width direction.

In addition, although the example in the case where the interlocking means 43 is provided in this embodiment was shown, the structure which opens the upper door 40 and the lower door 39 separately, without using the interlocking means 43 is shown. Even if the door is opened or closed, the installability of the device is not impaired.

In addition, the inter-door sealing member 50 is provided at the divided position of the upper door body 40 and the lower door body 39, so that the divided surface can be reliably sealed and the door body is divided by the partition. Since the length can be minimized, the installability of the apparatus can be improved. At this time, the divided positions of the doors become free ends, and are bent well by thermal deformation, pressurization, or the like. For this reason, it is difficult to ensure reliable sealing, but by using the door-to-door sealing member 50 having a rubber elasticity that can absorb this bending, for example, between the upper door body 40 and the lower door body 39. Sealability can be secured to prevent leakage.

In this embodiment, the opening and closing sequence of the upper and lower door bodies 40 and 39 is determined, and the upper door 40 is opened after the lower door 39 is opened. For this reason, since the interdoor sealing member 50 corresponded to the opening-closing procedure suitably, it can pressurize in the substantially vertical direction with respect to the interdoor sealing member 50, and therefore the interdoor sealing member 50 The sealing can be performed reliably with little operation force without damaging the material or the like. In addition, since the door body 39 which opens downward is first opened, water droplets falling due to the opening of the upper door body 40 can be received, thereby preventing the drop of water droplets to the outside of the apparatus.

In addition, although not shown, in the closed position of a door body, when the locking means which hangs and fixes the upper and lower door bodies 40 and 39 and the main body 1 is provided in the vicinity of the divided position of a door body, the vicinity of a divided position will be near. Is the position where the moving distance of the door body according to the opening and closing is the largest, and can lock the door body with the smallest force. Moreover, even when the upper and lower door bodies 40 and 39 are combined, the door body and the main body 1 can be locked, and the interlocking means 43 may also be included, and one place may be hooked with the main body 1.

In addition, although the door body was divided into two, it is also possible to set it as one door body 40, and to make it the structure which rotates upwards by the rotation arm 41. FIG.

In addition, in this embodiment, although the example which has the opening part 2 in the front surface of the main body 1 with the table-type dishwasher is shown, even if the built-in type or the main opening part 2 is formed upward, this invention is The door body of can be applied.

(Example 4)

9 is a side view of the dish washing machine according to the fourth embodiment of the present invention, in which the same components as those in the third embodiment are assigned the same reference numerals.

As shown in FIG. 9, two slide parts 35 are used as a support means which supports the upper door body 40 so that the upper door body 40 can move to the upper space of the main body 1. As shown in FIG. The slide part 35 is comprised from the slide groove 47 and the engaging part 48 provided in the edge part of the support arm 20a couple | bonded with it. In addition, the opening part 2 is comprised so that a part of the ceiling surface 49 of the washing tank 5 may be included.

By using the slide part 35, the movement trajectory of the upper door body 40 can be set arbitrarily, and the protrusion amount from the main body 1 of the door body 40 in the moving direction or the open state immediately after opening is set. Since it can be set, a suitable state can be obtained.

In addition, as shown in FIG. 9, a part of the upper surface portion 49 of the washing tank 5 is used as the opening portion 2, so that a wider and easier opening portion 2 can be obtained, and at the same time, the sealing portion on the front surface of the main body 1 is moved backward. It becomes easy to incline and sealing can also be performed easily. Moreover, a part of the side surface of the main body 1 can also be used as an opening part, and the dishwasher which is easy to put in and out of tableware etc. can also be provided in the side direction.

(Example 5)

10 is a side view of the dish washing machine according to the fifth embodiment of the present invention, in which the same components as those in the fourth embodiment are assigned the same reference numerals.

In the drawing, the dishwasher is provided with two door bodies 18 (lower door body 51 and upper door body 52) for closing the opening 2 of the washing tank 5, and the lower door body ( The shaft 51 is supported by the shaft 53 so as to be rotatable in the main body 1, and the upper door body 52 is equipped with the shafts 56, 57 using two rotating arms 54, 55 provided as support means. ) Is supported by the upper door body 52 and the main body 1 side by the spindles 58 and 59. An interlocking link (interlocking means) 60 is provided as an interlocking means for interlocking the upper and lower doors 52 and 51, and one end side thereof is an axis 61 integrally formed with the lower door 51. ), And the other end side is supported by a shaft 62 on the rotary arm 54 which is a supporting means of the upper door body 52. Here, the hole part 63 of the interlocking link 60 which engages with the spindle 62 has a long hole structure with a margin. In addition, supporting means such as the respective pivots, the rotating arms, the interlocking means 60, and the like are provided on both sides of the door 18, and the handle 64 for opening and closing the door 18 is a lower door. It is installed in the sieve 51.

Next, the operation and action will be described. The upper and lower doors 52 and 51 divided into two are configured to be opened and closed respectively, and the lower door 51 is moved downward by the rotation of the shaft 53. The upper door body 52 moves to the upper space of the main body 1 by the rotational movement and the rotational movement of the two rotary arms 54 and 55. At this time, the lengths of the rotary arms 54 and 55 are different, and the upper door body 52 moves while rotating. In addition, the linkage link 60, which is an interlocking means, connects the lower door body 51 and the rotary arm 54 supporting the upper door body 52, and when one door body is moved, the other door body is also interlocked. To move. For this reason, it is not necessary to open the two door bodies 18, and the two door bodies 18 can be opened at once by one opening operation, which greatly improves the convenience of use.

And the hole part 63 couple | engages with the spindle 62 is a long hole shape, and produces | generates the area | region which does not cooperate with the interlocking link 60. As shown in FIG. FIG. 11 is a middle step diagram when the handle part 64 of the lower door body 51 is pulled out, and the pivot 62 and the long hole 63 are moved even if the lower door body 51 is moved to the position shown in the drawing. Since the axis 62 is moved in the radial direction of the shaft by the allowance, the upper door body 52 does not move at all. Next, when the lower door body 51 is pulled out further, the upper and lower door bodies 52 and 51 interlock with each other by the action of the connecting link 60, and the upper and lower door bodies to the position shown in FIG. 18) open simultaneously. F shown in FIG. 12 is a range in which the lower door body 51 can rotate, and G is a range in which the upper and lower door bodies 18 interlock. In addition, as shown in Fig. 11, since the lower door 51 is opened first, and then the upper door 52 is opened next, water droplets and dirt attached to the upper door 52 are dropped out of the apparatus. You can prevent it.

In addition, from the position shown in FIG. 12 in the open state, within the range of the long hole 63 portion of the interlocking link 60, the upper door body 52 can be moved without interlocking with the lower door body 51. Therefore, as shown in FIG. 13, only the upper door body 52 can be moved further upward. Thereby, since the opening part 2 of the washing tank 5 can be opened more widely, confirmation and putting out of the to-be-cleaned object 6, such as a tableware, can be performed easily. In addition, when the washing basket is taken out as shown in the drawing, the withdrawal of the to-be-washed object becomes easier.

In addition, by increasing the allowance of the long hole 63, the area which is not interlocked can be increased. For example, when the height of the installation place is low, it is used in the state shown in FIG. 12, and when the installation height is high, the upper door It is also possible to use a method such as only opening the sieve 52 upward.

In addition, the maximum height at the time of opening the door body 18 can be adjusted by allowing the clearance amount of the long hole 63 to be adjusted, and the installation height is opened by opening the upper door body 52 to a height corresponding to the height of the actual installation place. It is possible to obtain a state of use utilizing the full. In addition, even in the interlocking means other than the present embodiment in which the hole of the interlocking link 60 is the long hole 63, the non-interlocking area can be adjusted, and the installation height can be maximized.

Next, when closing the door body 18 from the open position shown in FIG. 12, the lower door body 51 is operated and it moves to the position shown in FIG. In this state, since the portion of the shaft 62 has a margin, freedom exists in the movement of the upper door body 52, but a force is applied to the upper door body 52 in the closing direction due to the weight of the upper door body 52. Because of this, the upper door 52 is almost closed at the point in time when the lower door is shown in FIG. Further, when the lower door 51 is returned, the interlocking of the upper and lower doors 52, 51 is released by the long hole 63, so that only the lower door 51 operates, and therefore, FIG. It blocks to the occlusion position shown. In this closed position, the upper and lower door bodies 52 and 51 are not interlocked and exist as independent door bodies, and if the upper and lower door bodies 52 and 51 are individually protected, the water is assured. The opening 2 can be closed in a watertight manner.

Various types of opening and closing with one door body already exist and can be waterproofed relatively easily. However, when the plurality of door bodies 18 are interlocked, and the interlocking by the interlocking means is completely and uniquely performed as in the prior art, both doors are placed in a position where watertightness is maintained without problems if machining and assembly are carried out to an ideal dimension. Although the sieve can be blocked, in practice, there is always an error in parts due to processing or molding, an assembly error in assembling, etc., and therefore, this is not ideal. If the error of the parts is added to the assembly error or the like, the final error may be greatly increased, so that the waterproofing becomes incomplete when the linkage is unique. For example, as shown in FIG. 14, when the position of the axis 62 is slightly shifted | deviated, the upper door body 52 does not close completely and stops with the H part floating. For this reason, the sealing of the upper door body 52 becomes incomplete, and water leaks during washing | cleaning. Contrary to FIG. 14, when the upper door body 52 is excessively occluded, the lower door body 51 to be operated is not completely closed and the occlusion operation becomes heavy or, in severe cases, the occlusion becomes impossible or damaged. There is concern.

Therefore, since the doors can be closed in a sealable position by making the doors 51 and 52 not interlock with each other in the vicinity of the closed position, even if the doors 52 and 51 above and below are interlocked with each other, leaks are ensured. Can be prevented. If locking devices are provided in the upper and lower door bodies 52 and 51, respectively, it can be reliably locked to each predetermined position. In addition, when a part of the upper and lower door bodies 52 and 51 are polymerized, the other door body can be pushed into the outer door body, and the other door is positioned when one door body is positioned at the closed position. You can also run

In addition, the rotary arms 54 and 55 and the interlocking means 60 are provided on opposite sides of the door 18, and the actuation force of the interlocking means 60 acts equally to the left and right sides of the door 18. Therefore, the slave door 18 can be prevented from twisting, and the opening / closing operation of the door 18 can be smoothly executed.

In addition, in this embodiment, in order to provide the area | region which does not interlock with door bodies, the axis | shaft 62 part enables movement to the radial direction of an axis, specifically, the hole 63 of the part of the axis axis 62 is lengthened. In addition to the hole shape, various configurations are considered, such as elliptical shape, a large space in a circular shape, a non-circular shape such as an ellipse, or a different shape between the axial shape and the hole shape. The effect can be obtained.

Moreover, even when the axis 62 is provided in the interlocking link 60 and the elongated hole 63 which engages with the axis 62 is formed in the rotating arm 54, the same effect | action and an effect can be acquired. The same applies to the case where the hole of the axis 61 on the side opposite to the axis 62 is formed into a long hole shape.

Although not shown in particular, a flange portion is provided in order to prevent the long hole 63 inserted into the shaft 62 from being disposed, and a material, oil, and the like can be smoothly moved so as to smoothly move the shaft 62. Consideration is needed.

In addition, the upper door body 52 does not limit the opening / closing method of the door body 18, but the upper door body 52 pivots one support means (support arm) 65 fixed to the upper door body 52 ( 66) The same effect can be obtained for waterproofing in any configuration such as a rotational movement around. The same is true even if the opening and closing direction is left or right or the number of doors is three or more. In addition, although the interlocking means 60 was installed in connection with support means, such as the pivot 61 and the support arm 65 which support the lower door 51 and the upper door 52 movably, the upper and lower door bodies are provided. It may be provided in a place that moves simultaneously with opening and closing of 52 and 51, and the connection location of the interlocking means 60 is not limited to the position shown in FIG. 10 or FIG. 15.

Moreover, the axis | shafts 58 and 59 of the structure shown in FIG. 10 which install the door body 18 and the support means in the main body 1, and the axis 53 and 66 of the structure shown in FIG. 15 are the same base member. By supporting it in any configuration such as the washing tub 5 and other members, the error between the doors 51 and 52 is reduced, and the error of the position of the door 18 due to the assembly error is small. The sealing property of the door body 18 and the opening part 2 can be improved, and the occurrence of water leakage during operation can be prevented.

In addition, although the shafts 53, 58, 59, the rotational arms 54, 55, etc. were shown in the outer side of a wall clearly in the structure etc. shown in FIG. 10, storing in the wall surface of the main body 1 is carried out. It is possible to improve durability, such as preventing rust, deterioration, etc. by distinguishing the inside of the washing tank 5 from the area provided.

In addition, although the opening part 2 was made into the front surface of the main body 1, even if it is a structure which has an opening in a ceiling surface, a side surface, or several surface, it is the same. Moreover, it is applicable not only to a table-type dishwasher but also to the door body of a built-in type dishwasher.

Further, the interlocking means 60 is not limited to the link structure as in the third embodiment, but may be in other configurations, such as connecting with a wire or interlocking with a cog wheel, a belt, a chain, or the like. In addition, the present invention is not limited to mechanical means as in the interlocking link 60 of the present embodiment, and the same effect and effect can be obtained by using the electric means. For example, a drive motor for opening and closing the upper door body 52 and a position sensor for detecting the open / close position of the lower door body 51 are provided, and the upper door body 52 is opened with the drive motor in response to the output of the position sensor. It is also possible to set an area that does not interlock with an interlocking area by adjusting the degree.

(Example 6)

FIG. 16 is a side view of the dishwasher according to the sixth embodiment of the present invention, wherein like components are assigned the same reference numerals as those in the fifth embodiment shown in FIG. 10.

As shown in FIG. 16, the retractable expansion / retraction part 67 is provided in the interlocking link 60 which is an interlocking means, and the upper door body 52 is set as the structure which opens and closes rotational movement about the axis 68. As shown in FIG. . Moreover, the elastic part 67 is provided with the elastic body (compression spring) 69 which acts in the direction which shrinks the elastic part 67. As shown in FIG.

In the closed position of the door 18, each door 18 is independent by the expansion and contraction portion 67, and the lower door 51 and the upper door 52 can be closed in a sealable position. Therefore, despite the interlocking of the upper and lower door bodies 18, it is possible to reliably close and prevent water leakage. It is also possible to further open only the upper door body 52 at the time of opening.

Moreover, since the elastic body 69 provided in the expansion-contraction part 67 acts in the direction which compresses the expansion-contraction part 67, and since the interlocking link 60 is the shortest length, the handle part 64 of the lower door body 51 When closing with), the upper door 52 is closed. In the vicinity of the closed position, the upper door 52 receives a force in the closing direction by the force of closing the lower door 51. In addition, when the lower door 51 is pushed toward the closed position at this time, the pressing force by the compression spring 69 acts in the direction to close the upper door 52, thereby closing the upper door 52. Can be maintained. As a result, first, the upper door 52 is closed, and then the lower door 51 is closed, and in a certain order regardless of whether there are regions in which the doors 18 do not interlock. The door 18 can be closed. Since the order of door closure is not determined, the door bodies 18 can be prevented from coming in contact with each other and broken, and all the door bodies 18 can be closed.

In addition, when the elastic body 69 is made to act, even if the weight of the door (upper door body 52) other than the door body to operate does not act in the closing direction, the door body (upper door body 52) is first used. ] Can be blocked, so that the upper and lower door bodies 18 can be opened and closed by operating the upper door body 52, and the doors that open and close sideways can be coped, and the same effect can be obtained.

In addition, even in the case where a margin is provided such that the axis 62 is in the shape of a long hole 63 as in the fifth embodiment, the effect as shown in the present embodiment can be obtained by operating the elastic body 69 in the compression direction. have. In addition, when a separate elastic body is provided in the direction in which the upper door body 52 is closed, since the force in the closing direction is always applied to the upper door body 52, the upper door body 52 is always closed at the time of closing. Is closed first, and the occlusion order is made constant, so that a smooth and reliable occlusion operation can be performed.

(Example 7)

FIG. 17 is a side view of the dishwasher according to the seventh embodiment of the present invention, wherein like components are assigned the same reference numerals as those in the fifth embodiment shown in FIG. 10.

As shown in FIG. 17, the interlocking means is an interlocking wire 70. The interlocking wire 70 is provided on the lower door 51 by the connecting portion 71 and the upper door 52 by the connecting portion 72. The slide part 73 which enables the connection part 72 of the one end side of the to be moved is provided.

In addition, as shown, since the connection part 72 moves by the slide part 73, each upper door body 52 and the lower door body 51 are independent in the closed position of the door body 18, and each The upper door body 52 and the lower door body 51 can be closed in a sealable position, and the water leakage can be reliably prevented despite the interlocking of the upper and lower door bodies 18.

In addition, in the case of interlocking using the interlocking wire 70, unlike in the case of the link, the interlocking force does not act in the blocking direction, but as the self-weight of the upper door 52 acts in the blocking direction as shown in FIG. When the lower door 51 is moved in the closing direction, the upper door 52 is also blocked, so that the upper and lower doors 18 can be interlocked in both opening and closing directions. In addition, when the elastic body which presses the upper door 52 in the closing direction is actuated, since the upper door 52 is reliably closed, the operation | movement of opening and closing can be interlocked regardless of the presence or absence of the action of self-weight. . In addition, since the pressing force of the elastic body acts in the closing direction in the vicinity of the closed position by the action of the elastic body, the closing order is also constant and can be reliably sealed.

(Example 8)

FIG. 18 is a side view of the dish washing machine according to the eighth embodiment of the present invention, in which the same components as those in the fifth embodiment shown in FIG.

18, although the interlocking means 60 is the same as Example 5, the lower door 51 is superposed | polymerized in one part of the upper door 52 in the closed position, and the door 18 ), A sealing member 75 is provided in the polymerization portion 74 between the opening portion 2 and the upper and lower door bodies 52 and 51. Moreover, the handle part 64 which opens and closes the door body 18 is provided in the lower door body, and the locking means 76 which fixes the door body 18 and the main body 1 is provided in the lower door body 51 ) And the main body 1 are installed.

The basic operations and effects of opening and closing of the door body 18 are the same as those in the fifth embodiment, but a part of the upper and lower door bodies 52 and 51 is polymerized, and the lower door body 51 is closed at the closed position. The upper door body 52 is pushed in, and although the upper door body 52 is not interlocked at the closed position, only the lower door body 51 positioned at the outermost position is positioned in the closed state. It can be kept at a predetermined position. In addition, if the locking means 76 is provided only in the lower door body 51 which is located at the outermost part, it is possible to lock all the door bodies 18, leading to the simplification of the apparatus.

Moreover, since the joint surface of the upper and lower door bodies 52 and 51 is superposed | polymerized, since water is hard to leak to the exterior, sealing property improves. In addition, by using the sealing member 75, it is possible to seal more reliably and at the same time absorb some errors to ensure the sealed state.

In addition, the polymerization of a part of the door bodies can achieve the same effect even if the door body itself is polymerized and also a polymerization member such as a sealing member provided in the door body is polymerized.

(Example 9)

19 and 20 are side views and cross-sectional views of the dish washing machine according to the ninth embodiment of the present invention, in which the same components as those in the first embodiment shown in FIGS. 1 and 2 are given the same reference numerals.

This dish washer is provided with two door bodies 18 (lower door body 77 and upper door body 78) for closing the opening 2 of the washing tank 5, and each of the upper and lower door bodies 78 , 77 is provided as a support means for movably supporting the main body 1 with the support arms 81 provided integrally with the rotation points 79 and 80 and the upper door body 78. Moreover, the sealing member 82 which seals between the door body 18 and the main body 1 is the main body 1 side, The sealing member 83 which seals the divided position of the upper and lower door bodies 78 and 77 is It installs in an upper door body, and opens the lower door 77 first at the time of opening, and closes the upper door 78 first at the time of closure. Further, an interlocking means (interlocking link) 84 for interlocking the opening and closing operations of the two door bodies 18 is provided, and the handle portion 85 for opening and closing the door body 18 includes a lower door body ( 77, a tension spring 86 is provided as a pressing means for pressing the door 18 upward. In addition, in the open state of the door body 18, the uppermost surface of the door body 18 is located below the bottom of the washing basket 7 provided in the washing tank. Although not shown, the locking means which hangs and fixes the door 18 in the closed position of the door 18 is provided.

Next, the operation and action of the door body 18 will be described. The support means 79 and 80 for supporting the two upper and lower door bodies 78 and 77 divided into two upper and lower door bodies 78 and 77 are described. ) Is supported so as to be rotatable with respect to the main body 1, and is supported by the main body 1, so that stable opening and closing operation can be performed without fear of inadvertent movement of the upper and lower door bodies 78 and 77. . In addition, since the upper and lower door bodies 78 and 77 operate uniquely in a rotational motion shape, more stable opening and closing operation can be performed.

In addition, the door body 18 is the structure which set the opening-and-closing order of the upper and lower door bodies 78 and 77, and it is set as the structure which closes the lower door body 77 after closing the upper door body 78, First, an upper door body Sealing of the 78 and the main body 1 is reliably performed by the sealing member 82, and then the entire circumference of the lower door body 77 is sealed with the sealing member 82 and the upper door body 78 on the main body 1. By sealing with the sealing member 83 of the base of (), it can be sealed easily and reliably. In addition, when the front surface of the main body is the opening 2, unlike the case where the upper surface of the main body has an opening, if a small leak occurs, it leaks out of the apparatus, so that the effect of the present invention which can perform a more reliable sealing can be sufficiently exhibited. Can be.

Moreover, the door 18 is a structure which opens only to one direction of the opening part 2, and is convenient by the door 18 when it opens in the direction which does not prevent the removal of the to-be-cleaned thing 6, etc. Sex is not damaged. As shown in Fig. 20, by opening the door 18 downward, it is also possible to prevent the soup and water droplets from falling out of the washing machine when dispensing dishes or the like. Even when the washing basket 7 is pulled forward, there is no worry of spilling the soup, and taking out the to-be-washed object can be easily performed by pulling the washing basket 7 forward. In addition, since the door 18 does not open upward, even if it is installed in the ceiling surface, such as a dishwashing stand, confirmation in the washing tank 5 is not prevented.

In addition, even if it is open upward, it may be a configuration that does not interfere with use. In this case, since the door 18 opened downward does not exist, if the installation area of the floor area of the main body 1 is approximately, the device is installed. It is possible to improve the installability. Moreover, even if it is a structure open | released in the horizontal direction other than a vertical direction, the same effect can be acquired.

In addition, although the thing shown in FIG. 19 was set as the table top mounting type, the opening part 2 is formed in the front surface of the main body 1, and the upper and lower door bodies 78 and 77 are opened downward, and the space above the main body 1 is provided. Since it does not require, it can use for the door structure of the built-in type dishwasher of a front opening. Moreover, even if it is applied to a table-mounted dishwasher, since no space is required above the main body 1, the installation possibility becomes high even in a narrow kitchen space in Japan. Moreover, since the door body 18 is divided and the protrusion length toward the front is small, installation property improves more. In particular, when the lengths of the upper and lower door bodies 78 and 77 are set so that the tip positions of the upper and lower door bodies 78 and 77 substantially coincide in the open state of the door body 18, the door body 18 in the open position. Since the protruding length to the outside can be minimized, the area required for installing the dishwasher is the smallest. In addition, since the installation area is small, it is possible to cope with many installation changes such as vertically or horizontally, and can be suitable for the form of each household.

In addition, as shown in FIG. 19, the opening and closing sequence of the upper and lower door bodies 78 and 77 is determined, and in the opening, the opening and closing sequence of the upper door 78 is opened after the lower door 77 is opened. Since the sealing member 82 is properly configured, the sealing member 82 can be reliably sealed with a small operating force without damaging the sealing member 82 or the like.

In addition, in FIG. 19, when the interlocking means 84 which interlocks the opening / closing operation | movement of the upper and lower door bodies 78 and 77 is provided, and it opens with the handle part 85 provided in the lower door body 77, The doors 78 and 77 can be opened and closed in one operation. As a result, the convenience of use of the device is dramatically improved, and the order of opening and closing of the door body 18 can be regulated uniquely. Therefore, if the lower door body 77 is opened first, the operator It is not necessary to consider the opening and closing order of the door body 18. In addition, even if the lower door 77 is not completely opened first, the movement amount of the lower door 77 may be larger than the movement amount of the upper door 78, and specifically, the lower door 77 is rotated as shown in the drawing. By connecting the point 88a provided in the position extended to the opposite side of the point 79, and the point 88b provided in the position extended to the opposite side to the rotation point 80 by the interlocking means 84, Is realized.

In addition, the opening / closing procedure is not limited to the installation of the interlocking means 84, and the means for providing the handle portion 85 only to the door body 18 to be opened first even when the interlocking means 84 is not used. Can be specified.

In addition, since the interlocking means 84 has a link structure, the interlocking operation can be uniquely regulated both at the time of opening and at the time of closing, so that the interlocking opening and closing operation can be reliably performed for any door body operation. In addition, even when the upper door body 78 is operated, the lower door body 77 may operate in conjunction with any door body by moving in conjunction. In addition, the interlocking means 84 is not limited to the linkage structure, and the same effect can be obtained even with other configurations such as connecting with a wire or interlocking with a cog wheel, a belt, a chain, or the like.

In addition, with the structure shown in FIG. 19, since the interlocking means 84 does not come out of the main body 1, there is no possibility that a risk of pinching a finger between the links does not occur, and thus a good appearance can be obtained. .

In addition, as shown in FIG. 20, in the open state of the door body 18, the top surface 87 of the door body 18 is lower than the bottom portion 88 of the washing basket 7 provided in the washing tank 5. In this configuration, it is possible to pull out the washing basket 7 in the open state of the door 18, and to easily take in and out of the object to be cleaned 6 housed in the washing basket 7. You can run At this time, when the door 18 is opened downward, when the washing basket 7 is taken out, water droplets and the like can be prevented from falling to the front of the apparatus. In addition, if the roller 88c provided in the washing | cleaning basket 7 is a structure which slides the upper surface of the door 18, the washing | cleaning basket 7 can be stabilized in the extracted state, and the Cashiers can also be easily executed.

Moreover, since the tension spring 86 provided as the pressurizing means in FIG. 19 presses the door 18 upward, the opening / closing operation force of the door 18 becomes small and the operability improves. In addition, the impact force when the door body 18 falls freely due to gravity can be reduced, and the stress applied to the device is reduced, which leads to durability improvement and miniaturization of the device. In addition, the door body 18 is naturally closed in the vicinity of the closed position, and the door body 18 is naturally open in the vicinity of the open position, so that more comfortable operability can be obtained. In addition, the same effect can be obtained also by other elastic means, such as a torsion spring.

In addition, although not shown, the locking means which hangs and fixes the door 18 in the closed position of the door 18 is provided, and the door 18 is opened or the sealing part is incompletely in operation | movement by this. This prevents leakage or the like. Moreover, this locking means is the structure which hangs and fixes the door body 18 and the main body 1, or the structure which hangs and fixes the upper and lower door bodies 78 and 77, or the interlocking means 84 and the main body 1 The effect can be obtained in any configuration, such as by hanging. The door 18 may be locked at the same time as the closing operation of the door 18, or may be configured to move a lever or the like separately from the closing operation.

In addition, although the above description showed the example of the dishwasher which has the opening part 2 in the front surface by the table-mounting type, it is not limited to this, The same effect can be acquired even if it is a built-in type dishwasher. In addition, as in the conventional top rod type, as shown in Fig. 21, even if the structure has an opening 2 at the top, the opening and closing operation of the door body can be performed uniquely, so that the stable opening and closing operation can be executed. The same effect can be obtained. Moreover, although the surface containing the long side in the rectangular shape of the horizontal cross section of the main body 1 was made into the opening part 2, it is also possible to make the short side side into the opening part 2. As shown in FIG. Moreover, although the door body 18 was made into the structure which opens and closes in a vertical direction by making into 2 divisions, the structure divided into three or more is also considered. Moreover, even if it is the structure which rotates to the horizontal direction besides an up-down direction, the same effect can be acquired.

In addition, although the support means 79 and 80 were made into the rotational movement point, as shown in FIG. 22, you may have a structure, such as having the slide part 88d.

In addition, in FIG. 19, although the rotary motion points 79 and 80, the interlocking link 84, etc. were shown in the outer side of a wall for easy understanding, it is possible to accommodate in the inside of the wall surface of the main body 1, and it is a washing tank. (5) By distinguishing the inside from the installation area, durability can be improved such as prevention of rust, deterioration, and the like, and a good appearance can be obtained in which the linkage link 84 or the like is not exposed to the outside.

(Example 10)

FIG. 23 is a side view of the dish washing machine according to the tenth embodiment of the present invention, and the same components as in the fifth embodiment shown in FIG. 10 are denoted by the same reference numerals, and description thereof will be omitted.

The present dishwasher shown in FIG. 10 differs from the fifth embodiment shown in FIG. 10 in that the shafts 53, 58, and 59 are installed on the base member 89, and the upper and lower door bodies 18 are divided in their divided surfaces. It is the point which made the structure superpose | polymerize.

That is, the upper and lower door bodies 18 are configured to polymerize into the polymerization section 91 at their divided surfaces, and the door 18 and the opening 2 are sealed and the polymerization section 91 of the door 18 is sealed. The sealing member 92 which has elasticity is provided in this case, and it is set as the rubber material of hollow cross section here, for example.

When the operation and action are described, the upper and lower doors 52 and 51 divided into two are configured to open and close up and down, respectively, and the lower door 51 rotates downward by the rotation of the axis 53. The upper door 52 moves to the upper space of the main body 1 by the rotational movement of the two rotary arms 54 and 55. At this time, the length of the rotary arm 54 and the rotary arm 55 is different, and the upper door body 52 moves while rotating. In addition, the linkage link 60, which is an interlocking means, connects the lower door body 51 and the rotary arm 54 supporting the upper door body 52, and when one door body is moved, the other door body is also interlocked. To move. For this reason, it is not necessary to open the two door bodies 18, and the two door bodies 18 can be opened at once by one opening operation.

However, in the actual apparatus, there is a dimensional error or an assembly error in the door body 18, the rotary arms 54 and 55 or the pivot position or the interlocking means 60, etc., which support and move it, and thus the door body is located at a completely predetermined position. It is impossible to block (18), and a misalignment will necessarily occur. If the assembly error or the like is added to the error of the part, the final error may be greatly increased. For example, as shown in FIG. 24, when the position of the axis 62 is slightly shifted | deviated, since the upper door body 52 does not completely block and stops with the part of J floating, leakage occurs during washing. However, by using the sealing member 92 having elasticity, as shown in FIG. 25, the deviation can be absorbed by the elasticity, so that the sealing property can be secured and leakage can be prevented. In addition, the elasticity of the sealing member 92 also has the effect of bringing the sealing surface into close contact with each other. However, the main purpose here is to absorb the misalignment when the closed position of the door body 18 is shifted to secure the sealing.

On the contrary, when the upper door body 52 is excessively occluded in contrast to FIG. 24, the lower door body 51 to be operated is not completely closed, and in the case where the occlusion operation becomes heavy or severe, the occlusion is impossible or damaged. However, this defect can also be prevented through the sealing member 92 having elasticity.

As shown in Fig. 25, the sealing property can be secured, but since the amount of compression of the sealing member 92 varies depending on the place, the strength and weakness of the sealing exists. Thus, as shown in the partial cross-sectional view of FIG. 26, the rib 93 is provided inside the sealing member 92 to prevent the flow of washing water from directly colliding with the sealing member 92, thereby preventing the sealing member ( The classification is directed at a place where the amount of compression in Fig. 92 is small to prevent leakage. In addition, the shape, installation place, number, etc. of the rib 93 are not limited.

In addition, the door 18 is configured to polymerize the divided surface of the door 18 in a closed state, and the sealing property is improved by the polymerization portion 91 between the doors having a labyrinth structure. . Moreover, by using the sealing member 92 on the divided surface of the door 18, the shift | offset | difference of the door 18 by a dimensional error or an assembly error can be absorbed, and sealing can be performed reliably.

In addition, the spindle 53, which is a support means for the lower door body 51, and the rotary arms 54, 55, which are support means for the upper door body 52, are respectively provided in the main body 1, so that the opening and closing operation is performed. By becoming most stable, the error by opening and closing of the individual door bodies 51 and 52 can be minimized, and the shift | offset | difference by linkage can also be made small, and the sealing property improves.

In addition, the axis | shaft 53, 58, 59 which is the support means connection part which connects a support means (rotary arm 54, 55 and the support arm 53a) to a main body is provided in the single base member 89, The positioning accuracy of the sensor can be improved further when it is installed separately, and the assembly error can be reduced, whereby the shift of the door body 18 can be reduced during closing, and the waterproofness can be further improved. In the drawing, the base member 89 is connected to the main body 1, but the wall surface or other structural parts of the washing tank 5 may be configured as the base member 89.

In addition, by constituting one unit part with the base member 89, the shafts 53, 56, 57, 58, 59 serving as support members, the rotary arms 54, 55, and the interlocking means 60, the product assembly process In the above, only the unit parts united beforehand are attached to the washing tank 5 or the like, so that the assembly efficiency can be improved. At this time, the shafts 53, 58, and 59 of the support means connecting portion mounted on the base member 89 are all unitized to this unit part, so that the unit part is removed from the washing tank 5 or the door body in the assembling process. 18) can be easily installed by filling or screw fixing. In addition, since the machining of the shaft portion on the base member 89 can be performed in the state of the unit parts, it is also possible to fasten permanently, such as caulking, retainer ring, or the like, and to easily tighten the shaft portion without loosening. Since it can be performed easily, the reliability of components can be improved remarkably. In addition, since the positional relationship of the mounting portion of the support member is not shifted by disassembly of the product or the like, maintenance work such as replacement of parts can be performed easily and reliably.

In addition, when the base member 89 is used, the assembling error is small, so that the sealing property can be secured even if a sealing material excellent in elasticity such as the sealing member 92 is not used.

In addition, the rotary arms 54 and 55 and the interlocking means 60 are provided on the base member 89 on the opposite side of the door 18, respectively, and interlocking means equally to the left and right door 18. Since the actuation force of 60 acts, it is possible to prevent the subordinate door 18 from twisting and to reduce the displacement of the closed position of the door 18. In addition, the opening and closing operation of the door body 18 can also be performed smoothly.

In addition, although the rotating arm 54 was made into the curved structure rather than a straight line, it rotates when supporting means, such as rotating arms 54 and 55, are provided in the side surface of the main body 1, as shown in FIG. It is necessary to form the slit 94 in which the arms 54 and 55 move, in the main body 1, in order to shorten the length of this slit 94, and the intensity | strength of the main body 1 by the slit 94. While suppressing a decrease, a good appearance can be obtained. However, the shape of the rotational arms 54 and 55 is not limited, and even if it is any shape, such as linear form, there is no influence on the sealing effect.

In addition, although the sealing member 92 was made into the rubber material of a hollow cross section, the same effect can be acquired even if it is a lip shape or other structures, such as a foamable material.

In addition, the upper door body 52 does not limit the opening / closing method of the door body 18, but the upper door body 52 pivots one support means (support arm) 95 fixed to the upper door body 52 ( 96. The same effect can be obtained for waterproofing in any configuration, such as a rotational movement around the center. In addition, even if the opening / closing direction is left-right opening or the number of door bodies is three or more, it is the same. In addition, although the interlocking means 60 was installed in connection with the support means 95 which supports the door 18 to the door 18 so that opening and closing is possible, it is installed in the place which moves simultaneously with opening and closing of the door 18. The connection location of the interlocking means 60 is not limited to the position shown in FIG. 23 or FIG. 28.

In addition, in each said figure, although the axis, the rotation arm, etc. were shown to be in the outer side of the wall surface so that it may be understood well, it is possible to accommodate in the inside of the wall surface of the main body 1, and the inside of the washing tank 5 and the installation area | region are shown. By providing them separately, it is possible to prevent rust, deterioration, etc. of the pivot and the rotating arm.

In addition, although the opening part 2 was made into the front surface of the main body 1, it is the same even if it is a structure which has an opening surface in the ceiling surface, a side surface, or a some surface like the said Example. Moreover, it is applicable also to the door body of the built-in type dishwasher.

In addition, the interlocking means 60 is not limited to the link structure, and may have other configurations such as interlocking with a wire, a gear wheel, a belt, a chain, or the like as in the above embodiment, and an electrical means other than the mechanical means may be used. The same effect can be obtained.

The dishwasher of the present invention is configured to include a support means for movably supporting the door body to an upper space of the main body. The dish washing machine has a maximum height of the opening and closing trajectory of the door body even though the door body is opened upward. It can be made low and the length of protrusion to the front of the door body in an open state can be made small. Therefore, since the installation floor area is small and the height is also suppressed, the possibility of installing this dishwasher becomes high, and it can answer the request that it cannot install even if it wants to install. In addition, since the protruding length toward the front of the door body in the open state is also small, it is easy to check the inside of the washing tank, and it is possible to easily carry in and out of the object to be cleaned.

In addition, in the case where a plurality of door bodies are provided, the length of one door body is shortened, so that the protruding length of the door body toward the upper side or the front side due to the opening of the door body can be made smaller, thereby providing a more highly installable device. can do.

In addition, the present invention is to provide a support means for supporting the rotational movement of the plurality of door body to open and close the main body corresponding to each door body, each support means is configured to open all the door body to one side of the opening side As a result, each door body is supported not by the door bodies but by the installed main body, so that the door body can perform stable opening and closing operation. Moreover, since the said support means is set so that all the door bodies may open to the one direction side of an opening part, opening in the direction which does not prevent the removal of the to-be-washed object etc. does not impair the convenience of use. Moreover, if it is set as the structure which closes the other door body after closing the said one door body, it is not necessary to carry out all sealing simultaneously, and sealing can be performed easily and reliably.

In addition, when the length of each door is set so that the line unit value of each door in the open state of the door is approximately equal, the protruding length to the outside of the door in the open position can be minimized. As the area required for installation of the dishwasher becomes small, the possibility of installation in a kitchen or the like becomes high.

Further, by providing an interlocking means for interlocking the opening and closing operations of the door body, it is possible to open and close all the door bodies in one operation, and the convenience of using the dishwasher can be dramatically improved.

In addition, the present invention provides an opening and closing operation of a plurality of door bodies by forming an operating region in which the other door bodies do not operate in conjunction with each other in the operating range of opening and closing when one door body of a plurality of door bodies is opened and closed. Even in the case of interlocking with each other, waterproofing of all doors can be reliably performed.

Moreover, when this 1st and 2nd door body is closed, the 1st door body and the 2nd door body will be closed so that the sealing member which has elasticity may be interposed, and when opening / closing operation | movement of several door bodies is interlocked. Also in this case, the waterproofing of the door body can be reliably performed.
