Dish cleaning machine 1 particularly resemble shown in the figure be arranged on sink 51 below etc. under the occasion, because it is very low that the position is set, so go into directly to pack in tableware storage unit 5 or take out various tablewares, the user needs with one's back bent, it is very inconvenient to operate.But, allow after tableware storage unit 5 rises, pack into or take out the operation of various tablewares and sweeping operation etc. and will become and be easy to carry out in the rinse bath 3.

In addition, because the lifting position that tableware storage unit lifting drive 2 can make tableware storage unit 5 is set arbitrarily in the scope that can arrive, so the user can rise to arbitrarily on the height and position tableware storage unit 5 according to factors such as the height that height and user are set of dish cleaning machine 1, customs.The structure of tableware storage unit lifting drive 2 as shown in Figure 2, by be arranged on rinse bath 3 about two outside linkages 22 on two lateral surfaces drive be arranged on rinse bath 3 about two inboard linkages 21 on two medial surfaces.In inboard linkage 21, tableware storage unit 5 is taken in mounting or dismounting mode freely and is put on support rails (tableware storage unit supporting arrangement) 23.As shown in Fig. 3 A, the 3B, an end of inboard

pitman arm

24,24 connects mutually with turning cylinder 26, rotates under the driving of above-mentioned outside linkage 22; The other end of inboard

pitman arm

24,24 is provided with roller 25, above-mentioned rollers 25 makes support rails 23 with matching rise (moving) to the raised position shown in Fig. 3 B from the position of falling shown in Fig. 3 A, thereby the tableware storage unit 5 that is bearing on the support rails 23 is also moved up.In other words, inboard

pitman arm

24,24 is the swing arm that an end is driven, rotates, and these two swing arms are done to rotate synchronously; The roller 25 that is arranged on the other end slides along support rails 23.Two

inboard pitman arms

24,24 play the effect of parallel rod, make support rails 23 keep level to carry out the ascending, descending campaign.

One end of two inboard

pitman arms

24,24 is supported on respectively on the turning cylinder 26, turning cylinder 26 passes the sidewall 3a of rinse bath 3 as shown in Figure 5 respectively after installing containment member 30, the 1st, the 2nd outside pitman arm 27a in the outside linkage 22, the end of 27b are supported.

As shown in Fig. 4 A, 4B, in outside linkage 22, the 1st outside pitman arm 27a and the 2nd outside pitman arm 27b are connect by link arm 28, constitute parallel linkage.Drive unit 31 is driving the actuating arm 29 that connects mutually with the other end of the 1st outside pitman arm 27a and is doing to advance and retreat when moving, and outside linkage 22 promptly rotates, and rotates thereby also drive above-mentioned inboard linkage 21.

Drive unit about 31 is arranged on the back side one side of rinse bath 3 in couples, its operating process is: rotatablely moving of motor 32 becomes to make piston 34 to make the rectilinear motion that advance and retreat move in 33 inner conversions of cover bucket, makes the actuating arm 29 that connects mutually with its fore-end make advance and retreat again by piston 34 and moves.By two motors 32 are rotated synchronously, two drive units 31 are synchronized with the movement about making, thereby two outside linkages 22 are done to rotate synchronously about making, two inboard linkages 21 are also made driven in synchronism like this, difference can not occur between the adjustable height of support rails 23 left and right sides in the lifting moving process, thereby can make tableware storage unit 5 stably carry out lifting.In addition, though be to drive left and right two drive units 31 respectively here, also can adopt by 1 motor 32 to make two drive units 31 that the structure of interlock take place with two motors 32.

By resembling in the present embodiment, inboard linkage 21 is arranged on rinse bath 3 about on two medial surfaces, with outside linkage 22 be arranged on rinse bath 3 on the other side about on two lateral surfaces, just there is no need be provided with parts such as rotation washer jet, leftovers slag filter and drainage pipeline etc., on the bottom surface of rinse bath 3 spaceless lowering or hoisting gear be set, thereby can make tableware storage unit 5 realize elevating movements under the prerequisite that the setting of requisite inscape does not impact in to rinse bath 3.In addition, since inboard linkage 21 and outside linkage 22 be set at rinse bath 3 about on the inside and outside wall of two sides and be in mutually on the position that faces, therefore two sidewalls get final product about being used to transmit 26 need of driving shaft that drive power and penetrating, and are used to keep the containment member 30 of the sealing of rinse bath 3 also can realize very simply.In addition, because inboard linkage 21 and outside linkage 22 can be made by sheet material just connects, therefore, occupied volume is little, the minimizing of the dischargeable capacity in the rinse bath 3 can access effective inhibition, utilize seldom be provided with in the rinse bath 3 component parts about two sides just can constitute the lowering or hoisting gear of tableware storage unit 5.

The tableware storage unit 5 that is carried out lifting moving by above-mentioned tableware storage unit lifting drive 2 is inlayed on a plurality of positions with support rails 23 and is closed, and takes in mounting or dismounting mode freely and puts on support rails 23.Owing to when rinse bath 3 inside of leftovers slag filter etc. are swept, tableware storage unit 5 need be pulled down, the bottom surface of rinse bath 3 is exposed, therefore, when reinstalling, only close structure and just can on support rails 23, realize locating by simple edge.

On the support rails 23 that supports tableware storage unit 5, slipper 23a being embedded into like that among the inside groove 25a in the

roller

25,25 on the front end that is separately positioned on two inboard

pitman arms

24,24 as shown in Figure 5,

roller

25,25 can be free to slide.So, though on left and right directions, can realize the location, on fore-and-aft direction the state that slides easily, cause the tableware storage unit 5 that is bearing on the support rails 23 on fore-and-aft direction, to be moved, inwall easy and rinse bath 3 bumps.For this reason, under the occasion that the inwall of tableware storage unit 5 and rinse bath 3 comes in contact, for the contact of occurrence of large-area not, cause resistance, convex shape guide member 16 is set in vertical direction as shown in Fig. 2 and Fig. 3 preferably on the inwall of the front and back of rinse bath 3 to lifting moving.

Like this, even tableware storage unit 5 comes in contact on the inwall that is moved on the fore-and-aft direction with rinse bath 3 because of support rails 23, the contact of small size also only can take place under the effect of guiding to of convex shape guide member 16, can not produce big resistance for lifting moving.In addition, as shown in Figure 3, the contact position between the slipper 23a on two

rollers

25,25 and the support rails 23 can change along with the adjustable height change in location.Because support rails 23 is to be under the state that is arranged on two

rollers

25,25, therefore be placed on a side that has very big deflection or tableware storage unit 5 in the weight of the various tablewares in the tableware storage unit 5 and be coupled with under the occasion of excessive press pressure, support rails 23 exists the possibility that comes off from roller 25,25.In order to prevent such situation, as shown in Figure 5, the below of support rails 23 is provided with the below that reaches

roller

25,25, be coming off of bending-like prevents part 23b.Being provided with comes off prevent part 23b after, even be applied with the strength of tumbling from horizontal direction on support rails 23, coming off prevents that part 23b from will come in contact with roller 25, thereby maintains the bonding state between roller 25 and the support rails 23.

In the above-described configuration, by the descending operation button (lifting operation device) 6 on the upper edge portion that is arranged on rinse bath 3 the place aheads one side shown in Fig. 2 is carried out pressing operation, tableware storage unit lifting drive 2 is operated.But, the rising of tableware storage unit 5 move need rinse bath 3 is pulled out to from body 4 assigned position, promptly need rinse bath 3 is pulled out to make rinse bath 3 above fully open, the tableware storage unit 5 of opening portion above just can carry out when not having complete pull-out location under the state of hindering thing.Therefore, be arranged to like this, promptly only after detecting the pull-out location that rinse bath 3 has been pulled to regulation, just can operate by the action need that descending operation button 6 rises tableware storage unit 5.In addition, be under the rise state at tableware storage unit 5 and just rinse bath 3 pushed in the body 4, be in the tableware storage unit 5 of raised position and be placed on wherein each kind of tableware and will bump with the exterior region and the Kitchen stand 50 of body 4.For fear of such situation occurring, when tableware storage unit 5 is in raised position, the push operation of rinse bath 3 need be set for can not carry out.The formation block diagram of control system has been shown among Fig. 6.As shown in Figure 6, rinse bath is pulled out checkout gear 11 and is used to detect the pull-out location whether rinse bath 3 has pulled into regulation, the detection output that this rinse bath is pulled out checkout gear 11 is imported in the control module 10, and 10 operation inputs according to descending operation button 6 of control module come 2 motors 32 of drive unit 31 are carried out Synchronization Control.When control module 10 does not receive the detection output of pulling out checkout gear 11 from rinse bath, even then do not accept from the operator input signal of descending operation button 6 or the control operation that has operator input signal that motor 32 is started.Particularly, to pull out checkout gear 11 be that the assigned position whether assigned position on the rinse bath 3 has passed through on the body 4 is detected to rinse bath.Therefore, can adopt any switches such as machinery, electric, optics to constitute at an easy rate.

In addition, whether the rising extreme position checkout gear 12 of the rising extreme position by being provided for detecting tableware storage unit 5 and the falling-threshold position detecting device 13 that is used to detect the falling-threshold position can be in the locational state of falling-threshold to tableware storage unit 5 and detect.Then, when the detection output signal of falling-threshold position detecting device 13 was not input in the control module 10, control module 10 made the 14 generation work of rinse bath moving locking device.So, tableware storage unit 5 do not get back to the falling-threshold position, promptly can carry out the position of wash dishes in, can prevent to carry out mistakenly that rinse bath 3 is pushed operation in the body 4.In other words, the possibility that bumps such as tableware storage unit 5 and various tableware and body 4 can be eliminated.

Rising extreme position checkout gear 12 and falling-threshold position detecting device 13 also can adopt the rotational angle to the advance and retreat shift position of actuating arm 29, piston 34 or the 1st and the 2nd outside pitman arm 27a, 27b mode such as to detect, and can constitute simply with any switches such as mechanical, electric, optics.Descending operation button 6 can be by various switch morphosises, and the push type key switch that wherein forms water proof structure easily is optimal selection.This be because, can form like this from the little structure of the protrusion amount on surface, can be arranged on the upper edge portion of rinse bath 3, reduce to be subjected to easily water the influence of splashing, and body 4 between the gap.In addition, rising button 6a and decline button 6b are set respectively preferably in the descending operation button 6, operate like this than being easier to.During rising button 6a and decline button 6b were pinned, tableware storage unit lifting drive 2 drove tableware storage units 5 and rises; Push when removing, the rising of tableware storage unit 5 drives and promptly is stopped.Be arranged to like this tableware storage unit 5 is risen on the desirable arbitrary height position.In addition, even the pressing operation of rising button 6a or decline button 6b is also continuing, when rising extreme position checkout gear 12 or falling-threshold position detecting device 13 detect tableware storage unit 5 and have arrived rising extreme position or falling-threshold position, 10 of control modules are preferentially controlled tableware storage unit 5 and are stopped lifting, and no matter the pressing operation state of rising button 6a or decline button 6b.

In addition, also can be set at like this: only need decline button 6b is carried out pressing operation one time, step-down operation just will be carried out continuously.Like this, owing to monitor before tableware storage unit 5 arrived the falling-threshold position at falling-threshold position detecting device 13, control module 10 makes tableware storage unit lifting drive 2 operate always, therefore, tableware storage unit 5 is promptly turned back on the cleaning positions.After on the upper edge portion that descending operation button 6 is arranged on as described above rinse bath 3, be in beyond the state of pulling out at rinse bath 3, just can not operate descending operation button 6, therefore can prevent maloperation.In addition, the control circuit board etc. that is used for controlling the operation of dish cleaning machine 1 is arranged on the space that forms between the leading flank of rinse bath 3 and the gate on the front surface 7.Like this, control module 10 can just be arranged in the suitable space, is connected also to become with distribution between the descending operation button 6 and carries out easily.

In addition, after the substantial middle of the upper edge portion by descending operation button 6 being arranged on rinse bath 3, no matter the user stands in which side of the left and right sides of the rinse bath 3 that is drawn out, and operating all is easy to.But, if subscriber station under the occasion on the next door of the rinse bath 3 that is drawn out, descending operation button 6 will be positioned at user's oblique rear, not easy-operating situation might occur.In order to address this problem, descending operation button 6 can be located on the most maneuverable position of user.In addition, if be connected bad carrying out, can also adopt the wireless connections mode with distribution between the rinse bath 3.That is, descending operation button 6 is made the remote terminal that constitutes one with transmitter, and on rinse bath 3, receiver is set, the lifting moving of tableware storage unit 5 is carried out remote control, operability can be greatly improved like this.

But no matter descending operation button 6 with which kind of form constitutes, and user unrelated person such as child in addition all might occur and be in joyful and mishandled situation, thereby may make the various tablewares of packing into or taking out cause damage.In order to address this problem, as shown in Figure 6, in descending operation button 6, be provided with locking button 6c.After locking button 6c was pressed, tableware storage unit 5 was locked on the adjustable height position of setting, and the pressing operation that may be controlled to rising button 6a or decline button 6b does not respond.

In addition, the situation that just makes tableware storage unit 5 carry out lifting under user oneself or child's finger rides over state on the rinse bath 3 also might take place.Because tableware storage unit 5 is the clathrate structure, when tableware storage unit 5 was on the raised position, finger was easy to insert, and does not only point, and the situation that sandwiches foreign matter also may take place.In addition, foreign matter falls in the rinse bath 3 and situation that the user does not notice and spoon and fork also may take place in the situation that the lifting moving process of tableware storage unit 5 falls down.Cause under the state of obstacle for the lifting moving of tableware storage unit 5 at such foreign matter etc., tableware storage unit lifting drive 2 is broken down.And, the most importantly, must prevent the danger that might bring to the person.When lifting moving to tableware storage unit 5 taking place cause the state of obstacle, tableware storage unit lifting drive 2 promptly becomes overload, and the electric current that flows through in the motor 32 also will be an overload current.Therefore, as shown in Figure 6, be provided with the overload checkout gear 15 of the load current that is used to detect motor 32 in the present embodiment.

Like this, when load current sharply increase, when detecting overload, it detects output signal and will be imported in the control module 10, control module 10 stops the operation of motor 32 at once, make tableware storage unit 5 stop lifting moving, thereby personal safety is protected, and can trouble-savingly takes place.In addition, the overload detection method of being undertaken by overload checkout gear 15 is not limited to the method that the overload current to motor 32 detects, and adopts by detection to be applied to the pressure on support rails 23 grades and also to be fine from the methods such as pressure detecting that its variation detects overload.

Pull out checkout gear 11 and rinse bath moving locking device 14 when failing operate as normal at rinse bath, overload checkout gear 15 also can play double protection functions.Particularly, pull out checkout gear 11 at rinse bath and fail under the occasion of operate as normal, even do not move at rinse bath 3 under the state of pull-out location of regulation, tableware storage unit 5 also can carry out lifting moving.In addition, under rinse bath moving locking device 14 is failed the occasion of operate as normal, in tableware storage unit 5 descends mobile process, just can carry out pushing rinse bath 3 in the body 4 operation.No matter under above-mentioned which kind of situation, because tableware storage unit 5 or various tableware can be answered back to body 4, tableware storage unit lifting drive 2 will become overload, therefore, can make tableware storage unit 5 stop lifting moving by overload checkout gear 15.

In the embodiment of above explanation constitutes, make tableware storage unit 5 carry out comprising inboard linkage 21 in the tableware storage unit lowering or hoisting gear 2 of lifting moving, making two swing arms in the above-mentioned inboard linkage 21 is that

inboard pitman arm

24,24 combines with support rails 23, forms parallel rod.

In addition, employing makes cam rotate, make the mechanism that lifting moving take place support rails 23 also to be fine by the turning cylinder 26 that outside linkage 22 carries out rotating drive.

The structure that the lifting moving of tableware storage unit 5 can also adopt rack-and-pinion combination and miniature elevator mechanism etc. to drive in vertical direction.But, need on the sidewall of rinse bath 3, cut out the groove of vertical direction like this, the sealing susceptible to of rinse bath 3, and also there is problem the life-span aspect.Therefore, on the result, the structure that makes turning cylinder 26 pass sidewall in the present embodiment is optimal selection.

In addition, though driving the lifting drive of tableware storage unit lowering or hoisting gear has in the present embodiment taked to drive constituting of outside linkage 22 by drive unit 31, but, also can take mode by each turning cylinder 26 of the motor direct-drive that is provided with deceleration device, by making each motor synchronous work, while can make support rails 23 keep level to carry out lifting moving.In addition, on each side of rinse bath 3, respectively install a motor, 2 turning cylinders 26 are carried out interlock drive and also to be fine.In addition, adopt by the advance and retreat tooth bar that drives of drive unit 31 and make and be fixed on the mechanism that the gear on each driving shaft 26 rotates and also be fine.

Adopt words of the present utility model, owing to can make the lifting of tableware storage unit to height and position arbitrarily, even if being provided with under the very low occasion in position of dish cleaning machine, the operation of each dishware of packing in the tableware storage unit/take out also becomes and is easy to carry out, and therefore can provide a kind of dish cleaning machine easy to use.

In addition, installed and be used to make the tableware storage unit to carry out after the tableware storage unit lifting drive of lifting moving, the volume of rinse bath can not dwindle greatly yet, thereby a kind of volume and high dish cleaning machine of ease of use of can not increasing can be provided meaninglessly.
