Description

Dishwasher {DISHWASHER}

The present invention relates to a dishwasher, and more particularly to a dishwasher suitable for the built-in type.

A household dishwasher generally introduces tap water into the wash basin and stores it at the bottom thereof, and then operates a pump to draw and supply the stored water to the nozzle, and to spray the water vigorously from the nozzle to accommodate the wash basin. It has a configuration to wash one dish. The conventional dishwasher of this type has a structure in which a washing cabinet is disposed inside the housing, and a front door is provided with a door that rotates forward and downward, and withdraws the dish basket horizontally from the washing cabinet with the door open. It is.

Recently, with the spread of the system kitchen, a built-in type dishwasher for assembling in the system kitchen is commercially available. As a dishwasher suitable for a built-in type, what is described in Unexamined-Japanese-Patent No. 2000-139799 etc. is known. That is, this type of dishwasher is a so-called take-out dishwasher, and a washing cabinet having a dish basket for storing dishes is configured to be pulled out forward with a door serving as a front plate. In the state where the wash basin is drawn out, the upper surface of the wash basin is wide open so that dishes can be taken in and out of the upper part. It has a structure to block.

Such draw-out dishwasher requires consideration that is different from the dishwasher in which a conventional washing cabinet is fixed in a housing from the structural feature. Specifically, the following problems are encountered.

(1) In the draw-out dishwasher, since a washing pump, a drying fan motor, or the like is usually provided integrally with the washing machine, the movable part for drawing and storing is very heavy. Withdrawal and storage in the state where a large number of dishes are stored in the washing cabinet are added to the weight of the dishes, which is more heavy. From this point of view, there is a tendency that a large force is required for the withdrawal and storage operation of the washing chamber, and smooth opening and closing may be never performed.

(2) If the cabinet is not in close contact with the top cover when the cabinet is stored in the housing, water sprayed inside the cabinet may leak out of the cabinet to wet the kitchen or cause the dishwasher itself to malfunction.

(3) In the draw-out dishwasher, the top cover remains in the upper space in the housing when the wash cabinet is removed. Therefore, for example, when the washing tank is pulled out during the washing operation and the washing tray is pulled out, the sprayed water is attached to the lower surface of the upper cover, so that this water drop may fall out of the washing cabinet and leak out of the housing.

SUMMARY OF THE INVENTION The present invention has been made to solve such various problems, and an object thereof is to enable the opening and closing of a dishwasher to be smoothly opened and closed without requiring more force than necessary for drawing out and pressing the washing machine. To provide a dishwasher. In addition, another object of the present invention is that when the washing chamber is housed in the housing, the top cover reliably closes the upper opening of the washing chamber with high watertightness, so that no leakage of water out of the washing chamber occurs even during washing operation. To provide a dishwasher. Another object of the present invention is to provide a dishwasher in which water attached to the lower surface of the upper cover does not fall out of the washing cabinet even when the washing cabinet is pulled out during the washing operation.

The dishwasher according to the first aspect of the present invention has been made to solve the above problems, a washing machine having a front surface opened, a washing machine which can be pulled forward from the housing and provided with openings for storing and taking out dishes on the upper surface, and inside the housing. In the dishwasher provided with an upper lid for closing the upper opening of the washing chamber in the upper,

a) holding means for holding the upper lid so as to be movable upward and downward between a position at which the upper lid is closed and a retracted position upward when the washing chamber is housed in the housing;

b) actuating means for imparting force to the top cover to push up or push down the top cover in conjunction with the withdrawal or indentation operation of the wash basin;

c) a pressing means for selectively pressing the top cover in both directions of pushing up and down the top cover according to the position of the top cover.

In addition, "up-and-down movement" by the said holding means is not limited to the movement to a perpendicular up-down direction. Specifically, for example, the holding means may include a parallel link having one end pivoted on the upper cover and the other end pivoted on the housing, and capable of swingably holding the upper cover in a substantially horizontal state. .

In the dishwasher according to the first aspect of the present invention, in a state where the washing chamber is completely stored in the housing, the upper lid is in a position to close the upper opening of the washing cabinet, and the pressing means pushes the upper lid in the direction of pushing down, whereby the upper lid High watertightness between the cover and the wash cabinet is secured. In this state, when the withdrawal operation of the washing chamber is started by the user, the upper cover is pushed up against the pressing force by the pressing means by the actuating means, and when the upper lid is raised to a predetermined position by the pressing means, The pressing force reverses and acts to push up the top cover. For this reason, a certain amount of force is required when starting to take out the washing tub, but the auxiliary force of the pressing force is applied on the way, and the washing tub is pulled out smoothly without requiring a large force. In this way, since the upper lid is pressed in the pushing-up direction by the pushing means in the state where the washing chamber is completely drawn out, it is reliably held in a predetermined retracted position in the housing.

When the press-in operation of the washing chamber is started by the user from this state, the upper cover is pushed down against the pressing force by the pressing means by the actuating means in conjunction with this, and when the upper cover is lowered to a predetermined position, the pressing means The pressing force is reversed and acts to push down the top cover. Therefore, a certain amount of force is required when starting to press the washing chamber, but an auxiliary force of the pressing force is applied on the way, and the washing chamber is smoothly stored in the housing without requiring a large force, and the top cover is the upper surface of the washing chamber. Close the opening.

In this manner, in the dish washing machine according to the first aspect of the present invention, it is possible to smoothly take out and push in the washing machine without applying a large force more than necessary. In addition, since the top cover is pressed so as to be pressed down by the washing chamber in the state in which the washing chamber is completely stored in the housing, the upper lid is surely high in watertightness and closes the upper opening of the washing chamber. For this reason, even if water sprayed in the washing cabinet is applied at the time of washing, it does not leak out of the washing cabinet. In addition, in the state where the washing chamber is completely removed from the housing, the upper lid is reliably held in a predetermined retracted position in the upper portion of the housing by being pushed in the pushing direction, so that the upper lid is not undesirably lowered.

In the dishwasher which concerns on the said 1st invention, as one form of the said press means, it extends most in the middle point of the movement range of an upper cover, and produces the pressing force by compression all from the said intermediate point toward the both end sides of a movement range. It can be set as the structure containing a tension coil spring.

Moreover, as one form of the said operation means, the inclination part inclined toward the other provided in either the upper part or the upper cover of the washing | cleaning chamber, and the active part which contacts or approaches the inclination part in the state in which the washing | cleaning apparatus provided in the other side was accommodated. It includes, and can be configured to push up the upper lid by the active part in contact with the inclined portion and acting along the inclined surface when the washing chamber is taken out from the state stored in the housing.

On the other hand, in order to push down the upper cover, the operation means includes a projection protruding downwardly from the upper cover, and a contact portion in contact with the projection when the washing chamber is press-fitted in the washing chamber, and the washing chamber is pushed in from the withdrawn state At this time, the upper lid can be pushed down by contacting the protrusion with the protruding portion.

In addition, the holding means holds the upper cover with a predetermined margin in the left and right directions, and the upper cover is in contact with the upper edges of both sides of the washing machine during the strong side, both sides of the projection member for correcting the position in the left and right directions It can be set as the structure which it has in. According to this configuration, if the upper lid is lowered as described above when the washing chamber is press-fitted into the housing, the positional shift in the left and right directions is corrected while the two protruding members contact the upper edges of both sides of the washing cabinet. Therefore, since the top cover reliably drops to the position which appropriately closes the upper opening of the washing chamber, high watertightness can be ensured at all times.

The dishwasher according to the second aspect of the present invention has been made in order to solve the above problems, a washing machine having a front face opened, a washing machine which can be pulled forward from the housing and provided with openings for storing and taking out dishes on the upper face, and in the housing. An upper lid for closing the upper opening of the washing chamber, the upper opening being closed with the upper lid when the washing chamber is housed in the housing, and the upper lid being retracted upward in the housing when the washing chamber is withdrawn; In the dishwasher,

The bottom surface of the upper cover is formed in a curved or inclined shape which is inclined downward toward the periphery, and a water receiver is installed at a downwardly inclined end portion around the upper cover, and water flowing into the water receiver flows to a predetermined position. It is characterized by falling.

Here, the predetermined position is a position that is inside the washing chamber even when the washing chamber is pulled out most forward.

In the dishwasher according to the second invention, when water is applied to the lower surface of the upper lid during washing or rinsing, the water flows quickly on the curved surface or the inclined surface and is recovered to the drip tray. Then, it passes down the drip tray and finally flows down into the wash basin. Therefore, it does not remain long in the state attached to the lower surface of the upper cover. Therefore, even when the operation is paused during the washing or rinsing and the washing cabinet is withdrawn, the water attached to the lower surface of the upper cover falls directly onto the bottom surface of the housing, or leaks out of the housing to wet the bottom surface of the kitchen. Can prevent things. In addition, when the housing is made of a metal plate, rust can be prevented.

In the dishwasher which concerns on the said 2nd invention, as one aspect, it can be set as the structure which a water flow part is made into a groove | channel type | mold groove | channel, and water flows down by interrupting the said groove | channel. In addition, the trough can be configured to be integrally provided with a watertight sealing member provided around the lower surface of the upper lid. According to this, the configuration is simple and does not require much cost.

Moreover, it is more preferable if the lower surface of the upper lid is made of a material having hydrophilicity or subjected to processing to increase hydrophilicity. According to this configuration, the water attached to the lower surface of the upper cover spreads thinly, making it difficult to form large water droplets. Therefore, there is little possibility that water will fall directly, and it is possible to more reliably prevent the outside of the washing basin.

The dishwasher according to the third aspect of the present invention has been made in order to solve the above problems, and includes a housing having a front face opened, a washing machine which can be pulled forward from the housing and provided with openings for storing and taking out dishes on the upper face, and in the housing. An upper lid for closing the upper opening of the washing chamber, the upper opening being closed with the upper lid when the washing chamber is housed in the housing, and the upper lid being retracted upward in the housing when the washing chamber is withdrawn; The dishwasher is characterized in that the lower surface of the upper cover is made of a material having hydrophilicity or subjected to processing for increasing hydrophilicity.

That is, according to this structure, since the water attached to the lower surface of the upper cover spreads thinly, and it is difficult to form large water droplets, there is a small possibility that the water directly falls. As a result, even if the operation is paused during washing or rinsing, and the washing cabinet is withdrawn, water attached to the lower surface of the upper cover falls directly to the bottom surface of the housing, or leaks out of the housing and leaks to the kitchen floor. We can alleviate soaking.

EMBODIMENT OF THE INVENTION Hereinafter, the dishwasher which concerns on one Embodiment of this invention is demonstrated with reference to drawings. 1 and 2 are schematic side cross-sectional views showing the overall configuration of the dish washing machine according to the present embodiment, in which FIG. 1 shows a state in which a washing chamber is stored in a housing, and FIG.

First, based on FIG. 1 and FIG. 2, the schematic structure of this dish washing machine is demonstrated. A washing cabinet 2 having an upper opening 3 is disposed inside the housing 1 with the front surface open, and a dish basket not shown for aligning the cutlery is provided inside the washing cabinet 2. . The washing chamber 2 is integrated with the door 4, which also serves as a front plate, which closes the front opening of the housing 1, and according to the rail 5 which is installed approximately horizontally inside the wall on both sides of the housing 1; It is possible to draw out from the front. In the center of the bottom part of the washing | cleaning chamber 2, the rotatable arm 6 in which the some nozzle was formed in the upper surface is provided. At the bottom of the washing tank (2), the water tank (7) is arranged in communication, and under the bottom of the washing tank (2), a washing and drain pump (8) is arranged, and this washing and drain pump (8) When operating as a washing pump, water drawn from the reservoir 7 is sent to the arm 6 and sprayed from the nozzle into the washing tank 2. The rear surface of the washing tank 2 is connected to a flexible water supply pipe 9 having a water supply valve (not shown). When the water supply valve is opened, water supplied from an external faucet or the like is supplied through the water supply pipe 9. (2) It flows into me.

In the housing 1, the upper lid 10 for closing the upper opening 3 of the washing cabinet 2 is provided above the washing cabinet 2. The upper cover 10 is oscillated by a pair of left and right parallel links 20 in which one end is journaled inside the side wall of the housing 1 and the other end is journaled in the side of the upper cover 10. Supported. As shown in Fig. 1, in the state in which the washing compartment 2 is housed in the housing 1, the upper lid 10 comes into close contact with the upper surface of the washing compartment 2 and closes the upper opening 3. Meanwhile, as shown in FIG. 2, in the state where the washing chamber 2 is pulled forward from the housing 1, the upper lid 10 is held in the raised state while being pushed forward. In order to perform the up-and-down movement of the upper lid 10 in conjunction with the withdrawal and press-in operation of the washing chamber 2, the present dish washing machine uses a characteristic configuration. This configuration will be described in detail below.

3 and 4 are views showing the relationship between the upper part of the washing cabinet 2 and the upper cover 10, Figure 3 is a state in which the washing cabinet 2 is housed in the housing 1, and FIG. It is a state when 2) is slightly taken out from the housing 1. 5 and 6 are enlarged views of portions A and B in FIG. 3 and FIG. 4, respectively. FIG. 7 is a state when the parallel link 20 is seen from above in FIG. 3, and only the parallel link 20 is shown in sectional view. 8 is a top view of the upper lid 10, and shows only half as it is symmetrical in shape. FIG. 9 is a cross sectional view taken along the line C-C 'of FIG. 8; FIG. FIG. 10 is an enlarged view of part D of FIG. 9. 11 is a side view of the front portion of the top cover 10. 12 is a top view of the washing chamber 2, and the description of the inside of the washing chamber 2 is omitted.

As shown in FIG. 7, one end of one link 21 constituting the parallel link 20 is connected to the screw 21 and the nut 22 from the inside thereof with respect to the side plate 1a of the housing 1. It is rotatably attached by the other end, and the other end is rotatably attached to the side surface of the upper cover 10 by the screw 23. As shown in FIG. Therefore, as mentioned above, the upper lid 10 is movable up and down by the parallel link 20 in the state which maintained the horizontal state.

3 to 6, a gasket 110 made of a hollow elastic member is provided around the lower surface of the periphery of the upper lid 10. As shown in FIG. When the top cover 10 closes the wash bin 2, the gasket 110 is pressed between the top cover 10 and the periphery 201 of the wash bin 2, as shown in FIG. This ensures high watertightness.

As shown in Fig. 3, Fig. 4 and Fig. 12, protrusions 202 are formed at two positions protruding rearward from the upper end edges of the rear part of the washing chamber 2 (but Fig. 12 is a half face). Only one projection 202 is shown]. As is apparent from Figs. 5 and 6, the projection 202 has an inclined portion 202a curved approximately &lt;-&gt; On the other hand, as shown in Figs. 3, 4 and 8, at the rear end edge of the upper lid 10, the portion corresponding to the protrusion 202 protrudes downward and the horizontal cross section opens forward. A substantially inverted c-shaped support member 104 is formed. Moreover, inside the support member 104, the active part 105 which lightly contacts the said inclination part 202a in the state which the upper cover 10 closed the upper surface opening 3 protrudes downward is installed.

When the washing cabinet 2 is pushed into the housing 1 from the drawn out state, as shown in FIG. 6, the protrusion 202 of the washing cabinet 2 is connected to the opening of the supporting member 104 of the upper lid 10. As shown in FIG. It is inserted and, when the washing chamber 2 is press-fitted, it contacts the supporting member 104 and pushes it backwards. Then, the upper lid 10 descends to the lower rear while rotating about the shaft 21, and closes the upper opening 3 of the washing chamber 2 as shown in Figs. That is, the protrusion 202 and the supporting member 104 act to push down the upper cover 10 when the washing chamber 2 is press-fitted.

As shown in Fig. 5, in the state where the upper lid 10 closes the upper opening 3 of the washing compartment 2, the active part 105 of the upper lid 10 is the inclined portion of the washing compartment 2; It is in light contact with 202a. When the washing chamber 2 is withdrawn from the state completely contained in the housing 1 in this way, the inclined portion 202a also moves forward with the movement of the washing chamber 2, so that the active portion 105 is inclined ( It is pushed up while sliding according to 202a). As a result, the upper cover 10 is pushed up. That is, the inclined portion 202a and the active portion 105 act to push up the upper lid 10 when the washing chamber 2 is withdrawn.

As shown in Figs. 8, 9 and 10, the protruding member 102 is formed on the side of the upper lid 10 to protrude downward. Since both sides of the washing chamber 2 are held by the rails 5, the shaking is hardly generated in the left and right directions. On the other hand, the upper cover 10 is supported by the parallel link 20 so as to be able to swing as described above, it can take a certain amount of clearance in the left and right directions, causing shaking. However, when the upper cover 10 closes the washing compartment 2, the watertightness by the gasket 110 as described above cannot be secured unless the upper cover 10 is lowered to a predetermined position. Therefore, in this dish washing machine, the projection member 102 is provided so that the left and right shakes are corrected when the upper lid 10 is lowered, and the washing chamber 2 is brought into contact with a predetermined position.

In the rear part of the upper cover 10, the press mechanism 30 which presses the upper cover 10 is provided in accordance with the position within the vertical movement range of the upper cover 10. As shown in FIG. 13 and 14 are side views of the main part showing the relationship between the position of the upper lid 10 and the operating state of the pressing mechanism 30, and FIG. 13 shows that the upper lid 10 is the top opening of the washing chamber 2; (3) in the closed state (that is, the state in which the washing compartment 2 is housed in the housing 1), and FIG. 14 shows the state in which the upper lid 10 is pushed up (that is, the washing compartment 2 is in the housing case 1). Withdrawn state]. 15 is an enlarged view of the pressing mechanism 30, in which (a) and (b) correspond to FIGS. 13 and 14, respectively. 16 is a conceptual diagram showing an operating principle of the pressing mechanism 30. As shown in FIG.

As shown in Fig. 15, the pressing mechanism 30 includes a fixed plate 301 fixed to the housing 1, a movable member 310 rotatably supporting the upper lid 10, a fixed plate 301 and a movable member. It consists of a tension coil spring 314 connecting 310. The U-groove bearing 305 is formed in the stationary plate 301, and the bearing 305 supports the shaft 311 of the movable member 310. Thereby, the movable member 310 is rotatable about the shaft 311, but the range of rotation is to the position where the bottom part of the movable member 310 contacts the stopper 303, and the position which contacts the stopper 304. FIG. Each is regulated. The tension coil spring 314 spans between the pin 302 of the stationary plate 301 and the pin 312 of the movable member 310. Moreover, the U-shaped recessed part 313 formed in the upper part of the movable member 310 supports the circumferential rod-shaped pin 106 which protruded laterally from the upper cover 10. As shown in FIG.

As shown in Fig. 16, the movable member 310 is rotatable between the position where the pin 312 comes to R1 and the position to R3 about the support point Q (axis 311). On the other hand, since the tension coil spring 314 has one end fixed to the point P, the rotational trajectory for maintaining the same spring length becomes like a dotted line in the figure. That is, when the movable member 310 rotates as described above, since the rotation trajectory is located on the outside of the circle rather than the rotation trajectory of the same spring length, it is always in a tensioned state, and the pressing force due to the compression against it When the pin 312 is at R2, it is maximized, and it acts to rotate in both directions from that point. That is, when the pin 312 is between R1 and R2, the pressing force of the tension coil spring 314 acts to rotate the movable member 310 upward, and when the pin 312 is between R2 and R3. The pressing force of the tension coil spring 314 acts to rotate the movable member 310 downward. The pressing mechanism 30 presses the upper lid 10 upward or downward by this operation.

As shown in Fig. 13, when the upper lid 10 comes down while the washing chamber 2 is completely stored in the housing 1, the movable member 310 of the pressing mechanism 30 is pressed in the right rotation direction. Since the upper lid 10 is strongly pressed against the washing chamber 2, the adhesiveness is good and high watertightness is achieved. When the user wants to withdraw the washing tank 2, the spring 314 receives a repulsive force. However, the upper cover 10 is driven by the pushing force by the inclined portion 202a and the active portion 105. When it rises to an extent, the rotation direction of the movable member 310 by the pressing force of the spring 314 is reversed, and the upper cover 10 is pushed up by this pressing force. Therefore, even if it does not pull the wash bin 2 with a large force, the wash bin 2 opens smoothly. Then, in the state where the washing chamber 2 is completely pulled out, as shown in FIG. 14, the upper lid 10 is held in an elevated state by the pressing force of the spring 314 of the pressing mechanism 30. As shown in FIG.

When attempting to press the washing chamber 2 into the housing 1 from such a state, it will receive the repulsive force of the tension coil spring 314 initially. When the washing chamber 2 enters the housing 1, the upper lid 10 is lowered by the pushing force of the protrusion 202 and the supporting member 104 as described above, and lowers to some extent. The rotation direction of the movable member 310 by the pressing force of the tension coil spring 314 is reversed, and the upper lid 10 is pushed down by the auxiliary force of this pressing force. Therefore, even if the washing | cleaning container 2 is not pressed with a large force, the washing machine 2 is closed smoothly. Then, in the state where the washing chamber 2 is completely stored, as described above, the upper lid 10 is pressed against the washing chamber 2 by the pressing force of the tension coil spring 314 of the pressing mechanism 30, and the upper surface thereof. The opening 3 is tightly sealed.

In this manner, in the present dishwasher, smooth withdrawal and indentation of the washing compartment 2 can be achieved, and while the washing compartment 2 is stored, the upper lid 10 has a high watertightness to ensure washing ( In the state where the upper surface opening 3 of 2) is closed and the washing | cleaning chamber 2 is pulled out, the upper lid 10 can be reliably hold | maintained in the predetermined position of the upper space in the housing 1.

Next, the other characteristic of the dishwasher of this embodiment is demonstrated. As shown in Fig. 9, the lower surface 101 of the upper lid 10 made of synthetic resin is formed in an arch shape in which the center portion is high and gradually lowers toward both end portions. Moreover, fine unevenness | corrugation (fuzz) is formed in the surface of this lower surface 101, and the wettability (hydrophilicity) of the surface is high. Such fine wrinkle processing can use various conventionally well-known methods, such as sandblasting (method of blowing a fine particle diameter, etc.) with respect to the interior member processed to a predetermined shape by metal mold | die shaping | molding, for example. By such an arch shape and fine wrinkle processing, the water sprayed from the nozzle at the time of washing | cleaning, for example, adhered to the lower surface 101 of the upper lid 10 spreads quickly and thinly without forming a large droplet. When the amount of water attached is large, it flows along the slope in a wide spread state and reaches both ends. Therefore, it does not fall directly from the lower surface 101 of the upper lid 10 in a state of large water droplets.

As shown in Figs. 9 and 10, inside the gasket 110 provided on the lower surface of the periphery of the upper lid 10, a groove part 111 extending in a J shape is integrally provided. However, the trough portion 111 is not provided over the entire circumference, but is provided only at the rear side than the position F shown in Fig. 11, and the trough portion 111 is blocked in the middle at the position F, and the lower portion is lower. Section 112; By this structure, the following operation is achieved.

When the upper lid 10 is closed and washing or rinsing is performed, water sprayed from the nozzle reaches the lower surface 101 of the upper lid 10. As described above, the added water flows to both sides according to its shape and enters into the trough 111. And it flows along the trough part 111, and flows into the washing | cleaning tank 2 from the lower part 112. If, for example, the operation is paused during washing or rinsing and the washing compartment 2 is withdrawn to the housing 1, there is a high possibility that a lot of water is still attached to the lower surface 101 of the upper lid 10. However, the water is once collected into the trough portion 111 without falling directly into water droplets. Therefore, it is possible to avoid the water falling directly from the upper lid 10 and falling to the rear of the washing chamber 2 (out of the washing chamber) taken out. In addition, although the water collected by the trough portion 111 flows down from the lower portion 112 through the trough portion 111, even if the washing tank 2 is pulled out to the maximum, the lower portion 112 is directly below the lower portion 112. It is considered to be inside the wash chamber 2. As a result, no water flows out of the wash basin.
