Mode for Carrying Out the Invention

[0008] (Findings etc. on which the present disclosure is based) When the inventors arrived at the idea of the present disclosure, in the conventional door configuration having an upper door and a lower door, it was necessary to operate the unlocking operation of the door and the opening and closing operation of the door in different operation directions. Therefore, the inventors discovered problems such as the need to improve operability and also provide a mechanism for preventing the spraying of washing water by unlocking. To solve these problems, the inventors arrived at the constitution of the subject matter of the present disclosure.

[0009] Therefore, the present disclosure provides a dishwasher that can provide a user-friendly door opening and closing mechanism.

[0010] Hereinafter, embodiments will be described in detail with reference to the drawings. However, overly detailed descriptions may be omitted. For example, detailed descriptions of well-known matters or duplicate descriptions of substantially the same configurations may be omitted. This is to avoid making the following description overly redundant and to facilitate the understanding of those skilled in the art.

[0011] Note that the attached drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims thereby.

[0012] (Embodiment) Hereinafter, the best mode of the present embodiment will be described with reference to FIGS. 1 to 14.

[0013] [Overall Configuration] FIG. 1 shows a dishwasher according to Embodiment 1 of the present invention, which is a tabletop dishwasher installed in a built-in manner.

[0014] FIG. 1 is a perspective view of a dishwasher with the door in the closed state. FIG. 2 is a perspective view of the dishwasher with the door in the open state in Embodiment 1. FIG. 3 is a front view of the dishwasher in the state of FIG. 2.

[0015] In Embodiment 1, as shown in the drawings, with the dishwasher facing forward, the front side from the user is defined as the front direction and the back side as the back direction for the description. Also, in a front view, the upper surface side of the washing tub 3 of the dishwasher is defined as the upper side and the opposite side as the lower side, and further, when viewed from the front of the door 4, the right side is defined as the right direction and the left side as the left direction. Hereinafter, the description will be made.

[0016] As shown in FIGS. 1 to 3, the dishwasher 1 has a housing 2, a washing tub 3 provided in the housing 2, and an opening 5 in front of the washing tub 3, and a door 4 that opens and closes the opening 5. The door 4 is composed of a plurality of doors. Specifically, according to this embodiment, it has a first door 4a and a second door 4b.

[0017] The door 4 is configured to be openable and closable by the user gripping the opening and closing operation lever 8. A door lower recess 11 is provided directly below the opening and closing operation lever 8 located at the lower end of the door 4 so that the opening and closing operation lever 8 can be easily gripped. Also, an operation display unit 12 is provided on one side surface of the door lower recess 11.

[0018] By providing the operation display unit 12 directly below the opening and closing operation lever 8, the front surface of the door 4 has a clean design. Various button switches are attached to the operation display unit 12, and by the user touching or pressing a predetermined position of each switch, the door opening operation by the control unit 30 described later is made possible. Also, a panel or LED lamp for displaying the current situation and the pressed button is provided. In addition, it is also possible to set the operation actions such as the washing course and drying time of the dishwasher by operation through the operation display unit 12. Of course, the operation display unit may not be a button switch but an electrostatic touch type such as a touch panel.

[0019] The dishwasher 1 has a water storage tank 13 at the bottom for storing water for washing. The water storage tank 13 has a tank lid 14 on the upper surface of the tank convex portion so that the user can directly pour water into it. Since this tank lid 14 rotates upward, there is no need to pull out the tank when pouring water into the water storage tank 13, and water can be poured simply by opening the tank lid 14.

[0020] Also, the dishwasher 1 is provided with a cleaning nozzle 6 for injecting cleaning water rotatably inside the housing 2, and a dish basket 9 for placing dishes is arranged inside the housing 2.

[0021] The dish basket is provided with a large number of support pins of multiple shapes and is configured to be able to place bowls of various shapes. In this embodiment, the dishwasher 1 has, in addition to the dish basket 9 for placing plates, bowls, cups, etc., a dish basket upper shelf 10 for placing light dishes and small items.

[0022] The cleaning nozzle 6 injects cleaning water onto the objects to be cleaned, such as the dishes placed in the dish basket 9 and the dish basket upper shelf 10, to clean the objects to be cleaned. At this time, the cleaning nozzle 6 is mainly arranged to inject cleaning water from the lower part to the upper part of the housing 2 to clean the objects to be cleaned.

[0023] When the cleaning process is completed, the cleaning water is drained outside the machine by a drainage pump provided at the lower part of the housing 2.

[0024] The housing 2 is supported by a base frame. The cleaning water inside the housing 2 is heated to warm water by a heater 31, sucked in by a cleaning pump 32 from a food residue filter provided at the drainage port, pumped to the cleaning nozzle 6, and ejected from the ejection port toward the dishes for circulation. Thereby, the dishes are cleaned.

[0025] Also, a tower nozzle 7 is provided on the inner surface of the housing 2, particularly on the inner surface close to the back of the dish basket 9 in this embodiment. Similar to the cleaning nozzle 6, it injects cleaning water and enables cleaning of the objects to be cleaned, such as the placed dishes.

[0026] FIG. 4 is a perspective view of the dishwasher 1 when the door 4 is fully opened, as seen from below looking up at the door 4. An opening / closing operation lever 8 is provided at the lower end of the door 4. The door 4 also has a water guide plate 41 extending in the left-right direction on the inner surface of the door 4 on the front side in FIG. 4. The water guide plate 41 has its rear end fixed in FIG. 4 to serve as a shaft, and its front end hanging down due to its own weight. Since the front end is not fixed, it is configured to move freely according to the rotation position of the door 4 and its own weight. The front end forms an inclined surface facing downward on the front side, guiding the water droplets transmitted from the inner surface of the door 4 into the housing 2. Therefore, when the water droplets adhering to the inner surface of the door 4 after washing are transmitted, it prevents the transmitted water droplets from dripping from the tip of the door 4 and falling outside the dishwasher 1.

[0027] The opening 5 is configured to be opened and closed by the door 4. The door 4 has a packing for sealing the opening 5 in a watertight manner. The door 4 is composed of a door body divided into two parts vertically, and includes a first door 4a located above and a second door 4b located below. The door 4 is configured to open and close reversibly by an opening / closing mechanism of the door 4 described later. The first door 4a is in a substantially upright position in the closed state of the door 4 shown in FIG. 6(a), and in a substantially horizontal position in the opened state of the door 4 shown in FIG. 6(b). The second door 4b is in a substantially upright position in the closed state of the door 4 shown in FIG. 6(a), and in a substantially horizontal position in the opened state of the door 4 shown in FIG. 6(b). In the fully opened state where the door 4 is fully open, the first door 4a is located above the second door 4b, and the first door 4a and the second door 4b are substantially horizontal. In the opened state where the door 4 is fully open, the first door 4a is located above the second door 4b, and the first door 4a and the second door 4b are substantially horizontal.

[0028] FIG. 10 shows the functional configuration in the vicinity of the control unit 30 for controlling the dishwasher 1 in the first embodiment. The control unit 30 is realized by hardware such as a microcomputer, a microcontroller, and an integrated circuit.

[0029] The control unit 30 includes a process control unit 33, a door opening / closing detection unit 48, etc. These components are realized, in terms of hardware, by the CPU, memory, and other LSIs of an arbitrary computer, and in terms of software, by a program loaded into the memory, etc. Here, however, functional blocks realized by their cooperation are depicted. Therefore, it is understood by those skilled in the art that these functional blocks can be realized in various forms, such as by hardware alone or a combination of hardware and software.

[0030] [Latch interlocking mechanism when the door opens and closes] The door 4 is configured to be openable by a user gripping the movable opening / closing operation lever 8. The opening / closing operation lever 8 is configured to be interlocked with a latch 42 and an interlocking means 50.

[0031] FIG. 4 is a perspective view of the dishwasher 1 when the door 4 is opened, looking up at the door 4 from below, and FIG. 5 is a perspective view of the lower half of the dishwasher 1 when the door 4 is opened. As shown in FIG. 4, the opening / closing operation lever 8 provided at the lower end of the first door 4a is interlocked with the latches 42 provided at both the left and right ends on the inner surface of the first door 4a.

[0032] When the door 4 is closed as shown in FIG. 1, this latch 42 fits into the latch engagement grooves 43 provided at both ends near the opening 5 of the housing 2 shown in FIG. 5. At this time, the closed state of the door 4 is maintained, the door opening / closing detection unit 48 detects the closed state of the door 4, and the control unit 30 drives the cleaning pump 32 and the heater 31.

[0033] When the door 4 is closed and the opening / closing operation lever 8 is gripped by the user and a force is applied in the forward direction, the latch 42 also rotates in conjunction, and the maintenance of the closed state of the door 4 is released. At this time, the door opening / closing detection unit 48 detects the release of the closed state of the door 4, and the control unit 30 stops the cleaning pump 32 and the heater 31. Also, the operation display unit 12 displays that the door 4 has been opened.

[0034] FIG. 6 is a side view of the dishwasher 1 in which (a) shows the closed state of the door 4 and (b) shows the open state of the door 4. In FIG. 6, the side cover of the housing 2 is removed so that the internal structure of the housing side can be seen. Further, FIG. 7(a) is a simplified side cross-sectional view of the first door 4a in the state of FIG. 6(a), and FIG. 7(b) is a simplified side cross-sectional view of the first door 4a in the state of FIG. 6(b). FIG. 8 is a schematic front view of the first door 4a with the surface cover removed in the open state of the door 4, similar to FIG. 6(a) and FIG. 7(a).

[0035] Hereinafter, following the movement from FIG. 7(a) to FIG. 7(b), the interlocking operation between the opening / closing operation lever 8 and the latch 42 will be described.

[0036] When the user grips the opening / closing operation lever 8 and pulls it forward, the upper tip of the opening / closing operation lever 8 abuts against a lever connecting plate 46 provided at the lower center of the first door 4a directly above the opening / closing operation lever 8, and the lever connecting plate 46 is lifted upward. Subsequently, the upper tip of the lever connecting plate 46 lifted upward pushes up a sheet metal 45 extending in the left-right direction on the first door 4a. At this time, the sheet metal 45 is bent in a direction substantially perpendicular to the first door 4a, and the bent portion is pushed up by the upper tip of the lever connecting plate 46, so that it rotates toward the front side.

[0037] Since latches 42 are respectively attached to both ends of the sheet metal 45, when the sheet metal 45 rotates, the latches 42 rotate toward the front side at the same time, and the tip hook portions 47 formed in a hook shape of the latches 42 are retracted into the first door 4a.

[0038] Here, when the door 4 is in the closed state (FIG. 7(a)), since the tip hook portions 47 formed in a hook shape of the latches 42 are engaged with the latch engagement grooves 43, when the opening / closing operation lever 8 is pulled forward when the door 4 is in the closed state (FIG. 7(b)), the tip hook portions 47 are retracted into the first door 4a and the engagement with the latch engagement grooves 43 is released, so that the maintenance of the closed state of the door 4 is released.

[0039] On the upper tip, which is on the side opposite to the tip hook portion 47 of the latch 42, the lower end of the latch connecting spring 44 is connected. By fixing the upper end of the latch connecting spring 44 inside the first door 4a, the latch 42 is biased inside the first door 4a. When the opening / closing operation lever 8 is pulled, the tip of the latch 42 on the side where the latch connecting spring 44 is connected rotates downward, so the latch connecting spring 44 is pulled downward and is in an extended state (Fig. 7(b)). When the user releases their hand from the extended state of the latch connecting spring 44 like this, an elastic force acts in the direction for the pulled latch connecting spring 44 to return to its original state, and the opening / closing operation lever 8 is configured to return to its original position.

[0040] Specifically, when the user releases their hand from the opening / closing operation lever 8 in the extended state of the latch connecting spring 44 due to the rotation of the latch 42, the latch connecting spring 44 contracts and returns to its original length. As the latch connecting spring 44 contracts, the sheet metal 45 and the latch 42 rotate and return to their original positions, so the lever connecting plate 46 and the opening / closing operation lever 8 are also pushed back to their original positions.

[0041] Also, for example, even during the rotation of the door 4, when the opening / closing operation lever 8 is not being operated, the latch 42 is biased by a spring in an appropriate extended state, and the state where the opening / closing operation lever 8 is pushed downward by the lever connecting plate 46 as shown in (Fig. 7(a)) is maintained. When the door 4 is in the closed state and the opening / closing operation lever 8 is not being operated, the tip hook portion 47 of the latch 42 and the latch engagement groove 43 are engaged, and the closed state of the door 4 is maintained.

[0042] Next, the configuration of the door opening / closing detection unit 48 will be described. The frame X shown in Fig. 6(a), which is the open state of the door 4, is cut out and enlarged in Fig. 9(a). Also, the frame X shown in Fig. 6(b), which is the open state of the door 4, is cut out and enlarged in Fig. 9(b). The portion surrounded by the ellipse shown in Figs. 9(a) and (b) is defined as the door opening / closing detection unit 48.

[0043] The door opening / closing detection unit 48 provided on both end side surfaces inside the housing 2 includes a switch lever 481, a switch lever plate 482, and a microswitch 483.

[0044] The switch lever 481 is provided at a position where the tip hook portion 47 of the latch 42 that fits into the latch engagement groove 43 abuts when the door 4 is in the closed state. The switch lever 481 has a switch lever plate 482 at the tip on the side opposite to the side that abuts the tip hook portion 47. When the tip hook portion 47 of the latch 42 and the latch engagement groove 43 are engaged and the switch lever 481 is pushed up by the abutting tip hook portion 47, the switch lever plate 482 rotates about the switch lever rotation shaft 484. A microswitch 483 is disposed below the switch lever plate 482. When the rotated switch lever plate 482 presses the microswitch 483, the microswitch 483 becomes ON, and the control unit 30 detects that the door 4 has been closed. As shown in Fig. 9(a), the state where the door 4 is closed and the microswitch 483 is pressed is shown.

[0045] When the closed state of the door 4 is detected in this way, as shown in the functional configuration diagram of Fig. 10, an instruction is issued from the control unit 30 to turn on the cleaning pump 32 and the heater 31. When an instruction to start cleaning is given in this state, cleaning water is sent from the cleaning pump 32 to the cleaning nozzles 6 and the tower nozzles 7, and the cleaning water is jetted from each nozzle. At this time, the operation display unit 12 may display or notify that the door 4 is in the closed state and that operation and cleaning are possible.

[0046] Conversely, when the opening / closing operation lever 8 is pulled out with the door 4 in the closed state, the tip hook portion 47 formed in a hook shape of the latch 42 is retracted into the first door 4a. Then, since the tip hook portion 47 separates from the switch lever 481, the rotated switch lever 481 and the switch lever plate 482 return to their original positions about the switch lever rotation shaft 484. Therefore, the microswitch 483 returns to the state before being pressed by the switch lever plate 482, and the microswitch 483 becomes OFF, so the control unit 30 detects that the door 4 has been opened. As shown in Fig. 9(b), the state where the door 4 is open and the microswitch 483 is not pressed is shown.

[0047] When the open state of the door 4 is detected in this way, as shown in the functional configuration diagram of FIG. 10, an instruction is issued from the control unit 30 to turn off the cleaning pump 32 and the heater 31. Then, the supply of cleaning water to the cleaning nozzle 6 and the tower nozzle 7 is stopped, and the injection of cleaning water from each nozzle is interrupted. Therefore, when the user operates the opening / closing operation lever 8 to open the door 4, even if it was in the middle of cleaning, the injection of cleaning water is stopped, so that an accident such as water being sprayed from the opening 5 of the dishwasher 1 and wetting the user can be prevented. Also at this time, the operation display unit 12 may perform a display or notification indicating that the door 4 is in the open state and that operation and cleaning are not possible.

[0048] [Door interlocking mechanism 1 (link) when the door is opened and closed] The door 4 is composed of a door body divided into two parts vertically, and includes a first door 4a located above when closed and a second door 4b located below when closed. When the door starts to open, the first door 4a rotates upward toward the back side. When the door is fully opened, the first door 4a is supported at a position above the upper surface of the housing 2 so that the first door 4a is horizontal. Also when the door starts to open, the second door 4b rotates downward toward the front side. When the door is fully opened, the second door 4b rotates approximately 90° to a position where it is approximately aligned with the dish basket 9 in the housing 2 in a side view, and the second door 4b is supported so that it is horizontal. With such an opening / closing mechanism, the first door 4a and the second door 4b are configured to perform reversible opening and closing operations.

[0049] FIG. 14 is a side view of the dishwasher 1 when the door 4 is fully opened. FIG. 14 shows the internal structure of the side of the housing 2 with the side cover of the housing removed. FIG. 11 is a side view of the dishwasher 1 when the door 4 is fully closed. FIG. 12 is a side view of the dishwasher 1 when the door 4 is in the process of being opened or closed and the degree of opening of the door is small. FIG. 13 is a side view of the dishwasher 1 when the door 4 is in the process of being opened or closed and the degree of opening of the door is large. Also, for FIGS. 11 to 13, similar to FIG. 14, it shows the internal structure of the side of the housing with the side cover of the housing removed. Hereinafter, mainly using FIG. 14, the configuration for realizing the interlocking mechanism when the door 4 is opened and closed will be described.

[0050] The first door 4a is in a substantially horizontal position in the fully opened state of the door 4 as shown in the figure, and is rotatably supported by the first support member 51. The first support member 51 is formed to be curved in a U shape, one end of the U shape is fixed to the first support shaft 55, and the other end is fixed to the inner surface of the first door 4a.

[0051] The second support member 53 is fixed to the housing 2 and remains stationary even when the door 4 rotates. Therefore, the second support member 53 rotatably supports a plurality of support members and biases these support members and the housing 2. The second support member 53 has a shape extending from above to below on both side surfaces of the housing, and curves toward the front side from the middle of the lower part.

[0052] And the first support member 51 is rotatably supported with respect to the second support member 53 by the first support shaft 55 provided at the upper end of the second support member 53.

[0053] The second door 4b is in a substantially horizontal position in the fully opened state of the door 4 as shown in the figure, and is rotatably supported by the third support member 54. The third support member 54 is formed in a substantially fan shape, the central portion is fixed to the fourth support shaft 58, and the arc portion rotates. Also, the front end portion of the arc is fixed to the second door 4b.

[0054] The second support shaft 56 is provided at the curved lower end of the second support member 53 fixed to the housing 2. Therefore, the third support member 54 is also supported by the second support member 53 so as to be rotatable relative to the second support member 53.

[0055] The first support member 51 supporting the first door 4a and the third support member 54 supporting the second door 4b are supported not only by the second support member 53 but also by the link member 52. The link member 52 has a shape extending from above to below on both sides of the housing. A third support shaft 57 is provided at the upper end, and the first support member 51 is supported coaxially. A fourth support shaft 58 is provided at the lower end, and the third support member 54 is supported coaxially. The fourth support shaft 58 supports the rear end of the third support member 54, which is opposite to the end fixed to the second door 4b.

[0056] With this configuration, when a user pulls the opening / closing operation lever 8 to release the closed state and tries to open the first door 4a, the first support member 51 starts to rotate upward together with the first door 4a, starting from the first support shaft 55 (FIG. 12). Then, when the first support member 51 moves upward, the link member 52, which is supported coaxially with the first support member 51 by the third support shaft 57, is lifted upward (FIG. 13). Next, the lower end of the link member 52, which has been lifted upward, lifts the rear end of the third support member 54, which is supported coaxially with the link member 52 by the second support shaft 56, upward. Then, the front end of the third support member 54 is rotated toward the front together with the second door 4b, starting from the fourth support shaft 58 (FIG. 14). In this way, when the first door 4a opens, the second door 4b opens in conjunction with it.

[0057] The side surface of the housing 2 has a second rotation stopper 63, which is a flat plate arranged substantially horizontally at the lower end on the front side in a side view. The second rotation stopper 63 is provided at a position where it comes into contact with the end of the rotated third support member 54 opposite to the end to which the second door 4b is joined when the second door 4b is in a completely open state where the second door 4b is substantially horizontal. When the third support member 54 comes into contact with the second rotation stopper 63, the second rotation stopper 63 serves as a stopper, and the third support member 54 does not rotate any further in the opening direction.

[0058] Conversely, when the door 4 is returned from the open state to the closed state, the second door 4b is closed in conjunction with the first door 4a when the first door 4a is closed. Specifically, when the first door 4a is to be closed, the first support member 51 first starts to rotate downward together with the first door 4a, starting from the first support shaft 55 (FIG. 13). Then, when the first support member 51 moves downward, the link member 52, which is supported coaxially with the first support member 51 by the third support shaft 57, is moved downward (FIG. 13). Then, the lower end of the lowered link member 52 moves downward the rear end of the third support member 54, which is supported coaxially with the link member 52 by the second support shaft 56. Then, the front end of the third support member 54 is rotated toward the rear together with the second door 4b, starting from the fourth support shaft 58 (FIG. 12). In this way, the second door 4b is opened in conjunction with the first door 4a when the first door 4a is opened. It has been done.

[0059] When the first door 4a and the second door 4b rotate to the closed state as shown in FIG. 11, the tip hook portion 47 of the latch 42 and the latch engagement groove 43 fit together, and the door 4 is maintained in the closed state.

[0060] Furthermore, the link member 52 has a first spring 59 and a third spring 61. The link member 52, which extends in the vertical direction, has one protruding portion each in the front direction and the back direction in Fig. 11. The lower end of the first spring 59 is connected to the protruding portion on the back side. The upper end of the first spring 59 is connected to the first support member 51, and in the half-open state as shown in Fig. 13, the elastic force of the first spring 59 is balanced with the weight of the first door 4a, and the first door 4a comes to a stopped state.

[0061] [Door linkage mechanism 2 (spring) when the door is opened and closed] Also, the lower end of the third spring 61 is coupled to the protruding portion on the front side of the link member 52, and the upper end of the third spring 61 is coupled to a part of the side surface of the housing 2. In the semi-open state as shown in FIG. 13, the elastic force of the third spring 61 balances the weight of the first door 4a, and it comes to a stop state.

[0062] With this configuration, when the door 4 is in the closed state, the first spring 59 and the third spring 61 are in the extended state (FIG. 11). Therefore, when the user pulls the opening / closing operation lever 8 in the closed state of the door 4 and the closed state is released, and then opens the first door 4a and releases the hand, a force is applied in the direction in which the two springs contract, and the first door 4a is pulled upward and the upward rotation is started (FIG. 12). When the door rotates to the semi-open state with a large opening as shown in FIG. 13 due to the elastic force of the spring, the elastic forces of the first spring 59 and the third spring 61 balance the weight of the first door 4a and reach a stable state. Therefore, at the position as shown in FIG. 13, the upward rotation of the door stops during the opening of the door 4 (FIG. 13). Further, in order to open the door further, since the assistance by the elastic forces of the first spring 59 and the third spring 61 becomes small, it is necessary for the user to touch the door 4 again and directly apply a force. So when the user lifts the first door 4a from the state shown in FIG. 13, the front end of the rotated third support member 54 abuts against the second rotation stopper 63 provided at the lower end of the second support member 53, whereby the rotation of the link member 52 and the first support member 51 is physically stopped, and the door 4 cannot rotate any further. At this time, the opening 5 is in a completely open state, and the stop position of the door 4 at this time is configured such that the first door 4a and the second door 4b are substantially horizontal (FIG. 14).

[0063] When the door 4 is fully opened, if the upward rotation of the door is immediately carried out to the fully opened state, when the first door 4a has fully rotated upward, the rotation of the door 4 is physically stopped by the second rotation stopper 63. Therefore, the tableware placed in the tableware baskets 9 and 10 is impacted by the stop, the tableware is likely to contact each other and make a rattling sound, and the tableware may be damaged. On the other hand, if the upward rotation of the door is stopped by the elastic force of the spring during the opening of the door 4, the impact applied to the tableware placed in the tableware baskets 9 and 10 is alleviated compared to the former, and the contact between the tableware can be suppressed.

[0064] In addition, when the user pulls the opening / closing operation lever 8 in the closed state of the door 4 and the closed state is released, and then the user does not release the hand that opened the first door 4a and directly rotates the first door 4a upward, it can be immediately rotated to the fully opened state where the door 4 is in a substantially horizontal position as shown in FIG. 14 without stopping the rotation at the position as shown in FIG. 13.

[0065] Conversely, when the door 4 is returned from the opened state to the closed state, it is also configured to close while the elastic force of the spring acts. Specifically, when a force is applied in the direction in which the door 4 closes from the opened state as shown in FIG. 14, the first door 4a rotates downward with the help of its own weight. However, if the user lightly applies a force in the closing direction and then immediately releases the hand, the rotation of the door 4 stops at the position as shown in FIG. 13 It stops. This is because the elastic forces of the first spring 59 and the third spring 61 balance the weight of the first door 4a to reach a stable state. At the position as shown in FIG. 13, the downward rotation of the door stops during the closing process of the door 4. To further close the door, the first door 4a needs to be rotated downward. At this time, since the first support member 51 and the link member 52 pivotally supported coaxially are rotated downward, the first spring 59 and the third spring 61 are also stretched downward. Therefore, since the springs are in an extended state, it is necessary for the user to manually apply force to hold down the door 4 that repels in the opening direction due to the elastic force and close it. When the first door 4a and the second door 4b are rotated downward and reach the closed state as shown in FIG. 11, the tip hook portion 47 of the latch 42 and the latch engagement groove 43 are fitted, and the closed state of the door 4 is maintained. At this time, the opening 5 is in a completely closed state, and the stop position of the door 4 at this time is configured to be at a position where the first door 4a and the second door 4b are substantially vertical.

[0066] When closing the door 4, if the downward rotation of the door is carried out in one go to the completely closed state, when a force acting in the closing direction accidentally acts due to some reason, if the user's hand or finger is under the rotation trajectory of the first door 4a, an accident such as pinching the finger between the first door 4a and the second door 4b may occur. Also, due to the weight of the first door 4a, there is a possibility that the pinched finger may be injured. On the other hand, when the downward rotation of the door stops due to the elastic force of the spring during the closing process of the door 4, first, it is difficult for the door to hit the user's finger, and the impact given when the user's finger hits is also alleviated compared to the former case, and accidents and injuries to the user can be prevented.

[0067] In addition, when the user intentionally closes the door 4 in the open state of the door 4 and rotates the first door 4a downward without releasing the hand, it can be rotated in one go to the completely closed state where the door 4 is in a substantially vertical position as shown in FIG. 11 without stopping the rotation at the position as shown in FIG. 13.

[0068] Also, when the door 4 is stopped while being in the process of opening or closing as shown in FIG. 13, the second door 4b forms an inclined surface upward toward the front side in a side view. According to this structure, water droplets falling from the upper first door 4a or the water guide plate 41 are less likely to bounce outward, and the falling water droplets can be transmitted to the inside of the washing tub. Therefore, even when the door 4 is opened during washing, it is possible to suppress water from leaking outside the machine from the first door 4a.

[0069] [Door interlocking mechanism 3 when the door is opened and closed (maintaining the fully opened state)] FIG. 15 is a side view of the dishwasher 1 with an enlarged view of the vicinity of the first support member when the first door 4a is about to rotate to a substantially horizontal position. However, similar to FIGS. 11 to 14, the side cover of the housing 2 is removed so that the internal configuration of the housing side can be seen. Hereinafter, the rotation configuration for reaching the fully opened state of the door will be described with reference to FIGS. 13 to 15.

[0070] The U-shaped first support member 51 has an arcuate protrusion 64 at the tip of the end fixed to the first support shaft 55. When the first door 4a rotates, the arcuate protrusion 64 rotates together with the first support member 51. Also, above the back side of the side surface of the housing 2, there is a first rotation stopper 62. Since the first rotation stopper 62 is configured in a substantially T-shape, it has two depressions, and the T-shape is arranged in a direction rotated counterclockwise by about 90° as shown in FIG. 14. However, the lower end of the T-shape is pivotally supported by the housing 2 by a fifth support shaft 65, and the first rotation stopper 62 is provided so as to be rotatable about this shaft.

[0071] Also, the upper end of the first rotation stopper 62 is coupled to one end of a second spring 60 extending in the left-right direction. The other end of this second spring 60 is coupled to a part of the side surface of the housing 2. As shown in FIG. 11 and the like, this second spring 60 has a natural length when the first rotation stopper 62 is slightly inclined forward about the fifth support shaft 65, and the first rotation stopper 62 and the second spring 60 are fixed so as to be in a stable stopped state.

[0072] With this configuration, when the first door 4a is further manually rotated from the position of the door 4 in FIG. 13, just before the door 4 reaches the fully opened state as shown in FIG. 14, the tip of the arc of the arcuate projection 64 abuts against the depression above the first rotation stopper 62. When the door is further rotated from here, the tip of the arc of the arcuate projection 64 rotates while abutting against the end of the T-shape of the first rotation stopper 62 that extends in the forward direction (FIG. 15), and finally it gets over the first rotation stopper 62 (FIG. 14). Just before getting over, since the forward-side end of the T-shape of the first rotation stopper 62 is pushed by the arcuate projection 64, it rotates toward the back side with the fifth support shaft 65 as the starting point. FIG. 15 is exactly the figure when the first rotation stopper 62 is being pushed by the arcuate projection 64. When the first rotation stopper 62 is rotated toward the back side, the second spring 60 that was at its natural length is extended. And when the door is further rotated and the arcuate projection 64 gets over the first rotation stopper 62, since the second spring 60 tries to return to its natural length, a force acts in the direction of contraction due to the elastic force, and the first rotation stopper 62 rotates back to its original position where it tilts slightly toward the front side with the fifth support shaft 65 as the starting point, and the second spring 60 returns to its natural length (FIG. 14). The tip of the rotated arcuate projection 64 fits into the depression below the first rotation stopper 62, and the tip of the arcuate projection 64 catches on the forward-side end of the T-shape of the first rotation stopper 62. Here, since the first rotation stopper 62 that has returned to its original position is urged by the second spring 60 that is at its natural length, it is fixed at the position as shown in FIG. 14. Therefore, due to being caught in the lower depression, after the arcuate projection 64 gets over the first rotation stopper 62, the first door 4a maintains a substantially horizontal stopped state in the fully opened state as shown in FIG. 14 even when the user releases the hand.

[0073] In addition, in the fully opened state as shown in FIG. 14, since the U-shaped support member rotates approximately 90° upward, the first door 4a rotates to a substantially horizontal position in the opened state of the door. When the first door 4a rotates to a substantially horizontal position and the stopped state is maintained in this way, when the user opens the door, the door is not left in the opened state on the front side, so the space on the front side can be effectively utilized.

[0074] To fully open the door 4, as described above, the arcuate protrusion 64 at the tip of the first support member 51 needs to overcome the first rotation stopper 62.

[0075] Conversely, when returning the door 4 from the open state to the closed state, similarly, when the user rotates the first door 4a downward, the arcuate protrusion 64 needs to overcome the first rotation stopper 62. Specifically, when manually rotating the first door 4a downward from the position of the door 4 in Fig. 14, the tip of the arc of the arcuate protrusion 64 fitted in the depression below the first rotation stopper 62 rotates while contacting the front-side end of the T-shape of the first rotation stopper 62 (Fig. 15), and finally overcomes the first rotation stopper 62 (Fig. 13). Immediately before overcoming, since the front-side end of the T-shape of the first rotation stopper 62 is pushed by the arcuate protrusion 64, it rotates toward the back side with the fifth support shaft 65 as the starting point. Fig. 15 is exactly the figure when the first rotation stopper 62 is being pushed by the arcuate protrusion 64. When the first rotation stopper 62 is rotated toward the back side, the second spring 60, which was at its natural length, is extended. And when the door is further rotated and the arcuate protrusion 64 overcomes the first rotation stopper 62, since the second spring 60 tries to return to its natural length, a force acts in the contracting direction due to the elastic force. The first rotation stopper 62 rotates back to its original position where it tilts slightly toward the front side with the fifth support shaft 65 as the starting point, and the second spring 60 returns to its natural length (Fig. 13). The tip of the fully rotated arcuate protrusion 64 fits into the depression above the first rotation stopper 62, and the tip of the arcuate protrusion 64 catches on the front-side end of the T-shape of the first rotation stopper 62. Here, since the first rotation stopper 62 that has returned to its original position is biased by the second spring 60 at its natural length, it is fixed at the position as shown in Fig. 14.

[0076] Therefore, due to the first rotation stopper 62 being caught in the upper depression, after the arcuate protrusion 64 overcomes the first rotation stopper 62, the door 4 is in a semi-open state during rotation as shown in Fig. 13. Even if the user releases the hand here, the first door 4a will not return to the fully open state as shown in Fig. 14.

[0077] [Action direction when opening and closing the door] The door 4 is configured to be openable and closable by having the user grip the movable opening and closing operation lever 8. Here, as described above, when the user grips the opening and closing operation lever 8 and pulls it forward, the closed state of the door 4 is released, and the door 4 is configured to rotate and open. At this time, the direction in which the user pulls the opening and closing operation lever 8 is the direction of P shown in FIG. 14, which is a substantially horizontal direction. On the other hand, when the closed state of the door 4 is released, the first door 4a rotates upward and opens, and the rotation direction is the direction of Q shown in FIG. 14, which is a substantially vertically upward direction.

[0078] Therefore, when the user operates the opening and closing operation lever 8 to open the door 4, the direction in which the user releases the closed state and the direction in which the first door 4a opens are configured to be different by approximately 90° or more. As a result, if the user tries to open the door 4 during the cleaning operation of the dishwasher 1, since there is a little time between operating the opening and closing operation lever 8 and the door 4 opening, the door opening and closing detection unit 48 detects the release of the closed state and secures the time to stop the drive of the cleaning pump before the door 4 can be opened. Therefore, an accident such as water sprayed from the nozzle flying outside the machine when the door 4 is opened can be prevented.

[0079] However, on the other hand, when the door 4 is in the closed state, after gripping the opening and closing operation lever 8 and pulling it forward, the user can open the door 4 by rotating it upward without changing the hand that grips the opening and closing operation lever 8. According to this configuration, the user can perform a series of operations from pulling the opening and closing operation lever 8 forward to rotating it upward in a series of actions. Of course, when closing the door 4 in the open state, the user presses a part of the first door 4a and rotates the door 4 downward, and finally applies a force toward the back and pushes it in, then the latch fits and the closed state is achieved. Therefore, a series of operations from rotating downward to making the door 4 in the closed state can also be performed in a series of actions. Thus, according to the configuration of the present embodiment, the user can safely and smoothly perform the opening and closing operation of the door 4.

[0080] [Shape and positional relationship of the door] Subsequently, the detailed shapes of the first door 4a and the second door 4b and the closing method will be described.

[0081] When the opening 5 is closed, the first door 4a is closed so as to cover the second door 4b which is lower in height than the first door 4a. Here, a part of the inner surface of the first door 4a is located above the upper end of the second door 4b. Furthermore, the upper end 16 of the second door 4b is in contact with a part of the inner surface of the first door.

[0082] The first door 4a has an inner closing portion 15 protruding from the inner surface, and when the door 4 is closed, the upper end 16 of the second door 4b is in contact with the inner closing portion 15. At this time, the entire surface of the opening 5 is closed by the second door 4b and the inner closing portion 15.

[0083] When the contact portion between the second door 4b and the inner closing portion 15 is defined as the inner door contact portion, the outer surface of the inner door contact portion is covered by the first door 4a, so that the inner door formed by the second door 4b and the inner closing portion 15 and the outer door formed by the outer surface of the first door 4a close the opening 5 with a double - door structure. However, as shown in FIG. 1, it is formed as a single - door by the first door 4a in appearance.

[0084] With such a double - door structure, it is possible to more reliably prevent the washing water from flowing out of the machine. The washing water jetted from the nozzle during washing first hits the inner closing portion 15 and the inner surface of the second door 4b. At this time, the narrower the width between the inner closing portion 15 and the second door 4b, the lower the probability that the jetted water passes through between the inner closing portion 15 and the second door 4b and hits the first door 4a. Furthermore, when the second door 4b and the inner closing portion 15 are in contact with each other to form the inner door contact portion, the probability that the jetted water passes through and hits the first door 4a becomes even lower.

[0085] According to this configuration, even when the door 4 is in the open state, as shown in FIGS. 12 to 14, mainly the tip of the inner closing portion 15 is located deeper than the second door 4b in a side view. Therefore, even if the water adhering to the inner closing portion 15 after being jetted spreads toward the tip of the inner closing portion 15, the water droplets can be received by the second door 4b, so that it is possible to prevent the water droplets from dripping outside the machine.

[0086] Also, a water guide plate 41 that guides water droplets transmitted from the inner surface of the door 4 into the housing 2 is also located inside the dishwasher tub from the tip of the second door 4b in a side view when the door 4 is in the open state as shown in FIGS. 12 to 14. Specifically, the water guide plate 41 has its rear end fixed to the inner surface of the first door 4a, and its front end hanging down due to its own weight. Since the front end is not fixed, the fixed rear side serves as an axis, and it is configured to move freely according to the rotation position of the door 4 and its own weight. The front end forms an inclined surface downward toward the front side, guiding the water droplets transmitted from the inner surface of the door 4 into the housing 2. And when the water droplets adhering to the inner surface of the door 4 after washing are transmitted, even if the transmitted water droplets drip from the tip of the door 4, the inclined surface on the front side of the water guide plate 41 is located inside the dishwasher tub from the tip of the second door 4b in a side view, so that the water droplets can be prevented from falling outside the dishwasher 1.

[0087] [Water sealing member of the second door 4b] Next, the sealing method near the second door 4b will be described. FIG. 16(a) is a cross-sectional view of the inner door contact part in the closed state of the door 4. FIG. 16(b) is a cross-sectional view of the tip of the second door 4b in the open state of the door 4. Hereinafter, it will be described with reference to FIGS. 4, 5, and 16.

[0088] The tip of the second door 4b has a first water sealing member 17 extending left and right. The first water sealing member 17 is provided to protrude forward with respect to the second door 4b. In the closed state of the door 4, as shown in FIG. 16(a), the first water sealing member 17 contacts and seals the inner closing portion 15 in a substantially vertical direction. By sealing in such a substantially vertical direction, the inner door contact part can be reliably sealed. Also, since only the space between the second door 4b and the inner closing portion 15 is covered by the seal, the amount of water directly sprayed on the water sealing member is small, and the damage to the water sealing member can be suppressed, so that the deterioration of the seal can be delayed.

[0089] Further, the tip of the first water seal member 17 has a substantially uniform V-shape. When the door 4 is opened, as shown in Fig. 16(b), a small amount of water can be received in the V-shaped space portion 18 of the first water seal member. With this configuration, even if a little water drips from the tip of the inner closing portion 15 when the door 4 is opened, the V-shaped space portion 18 can receive the water, so that the water can be prevented from dripping outside the machine.

[0090] Furthermore, the second door 4b has second water seal members 19 shown as ellipses in Fig. 5 at both the left and right ends of the first water seal member 17. The second water seal member 19 has a front portion 21 and a corner portion 20 that extend outward in the left-right direction of the first water seal member 17. Also, the inner closing portion 15 has recesses 22 at both the left and right ends and an inclined surface 23 that slopes downward on the back side in order to be sealed by the water seal member. When the door 4 is closed, the left side surface of the corner portion 20 contacts the inner surface of the housing 2, the upper surface of the corner portion 20 contacts the annular packing 24 provided so as to surround the periphery of the cleaning tank, and the front side surface of the corner portion 20 contacts the inclined surface 23. The width of the corner portion 20 is configured to be the same as the width of the annular packing 24. Furthermore, the front portion 21 is in contact with the recess 22 of the inner closing portion 15, and from these configurations, the corner portion 20 and the front portion 21 of the second water seal member 19 and the inner surface of the housing 2 and the inner closing portion 15 are sealed.

[0091] Also, the second door 4b has third water seal members 25 that extend left and right on a flat plate on the back side opposite to the first water seal member 17. The third water seal member 25 contacts in a substantially vertical state so as to cover the gap between the housing 2 and the bottom surface of the second door 4b when the second door 4b is in the closed state, so that the gap between the housing 2 and the bottom surface of the second door 4b is sealed.

[0092] Due to these configurations, the water droplets hitting the periphery of the second door 4b are surely sealed without leaking outside the machine.

[0093] In the closed state of the door 4, these sealing members of the second door 4b seal the vicinity of the inner closing portion 15 and the second door 4b, and further, the first door 4a is closed so as to cover the second door 4b. Although only the sealing members have low sound insulation performance, in the present embodiment, since it is a double-door structure in which the outer surface of the sealing member provided at the inner door contact portion between the second door 4b and the inner closing portion is further closed by the first door 4a, it is possible to suppress the water hammer sound during cleaning leaking from the inner door contact portion. With this configuration, the dishwasher 1 can achieve cleaning with less noise.

[0094] As described above, the dishwasher of the embodiment is configured.

[0095] [Effects and the like in the present embodiment] According to the cleaning device according to the present embodiment, the following effects can be achieved.

[0096] The dishwasher 1 according to Embodiment 1 of the present disclosure includes a housing, a washing tub provided in the housing for accommodating an object to be cleaned, a door for closing the opening, an opening provided in the washing tub, and a movable opening / closing operation lever for opening and closing the door at a substantially tip position of the door. When the door is in the open state, by gripping the opening / closing operation lever and pulling it forward, the closed state of the door is released, and the door is configured to rotate and open.

[0097] With such a configuration, when the user sets the door 4 to the open state, the release of the closed state and the rotation of the door 4 can be realized only by a series of operations by a single opening / closing operation lever 8, and the operability can be improved.

[0098] The dishwasher 1 according to Embodiment 1 of the present disclosure is configured such that the door rotates upward. When the door is in the closed state, the opening / closing operation lever is provided at the lower tip of the door. The direction when pulling the opening / closing operation lever is substantially horizontal, and the direction in which the door rotates is substantially upward.

[0099] With such a configuration, it is possible to change the direction of releasing the closed state and the direction in which the door 4 opens. As a result, when opening the door 4 during the washing operation, in order to prevent the injected water from splashing outside the machine, the washing operation can be stopped by only operating the release of the closed state, and then a two-step operation of opening the door 4 can be performed. Therefore, it is possible to suppress the occurrence of accidents such as the user being splashed with the injected water.

[0100] The dishwasher according to Embodiment 1 of the present disclosure includes a washing pump that supplies washing water into the washing tub. When the closed state is maintained, the washing pump is driven, and when the closed state is released by the opening / closing operation lever, the driving of the washing pump is stopped.

[0101] With such a configuration, when opening the door 4 during the washing operation, the washing operation can be stopped by only operating the release of the closed state so that the injected water does not splash outside the machine. Therefore, it is possible to suppress the occurrence of accidents such as the user being splashed with the injected water.

[0102] The dishwasher 1 according to Embodiment 1 of the present disclosure has a door composed of a plurality of doors, and the first door is a door that rotates upward to open, the second door is a door that rotates downward to open, and when the first door opens and closes, it is provided with an interlocking means for interlocking the second door. In the closed state of the door, when the opening / closing operation lever is pulled, the first door and the second door have a pattern of stopping during the opening process by the interlocking means.

[0103] With such a configuration, it is possible to reduce the impact on the tableware caused by the door 4 opening all at once. Therefore, it is possible to suppress the generation of noise and damage to the tableware due to the collision between the tableware and the tableware basket 9 or between the tableware.

[0104] The dishwasher 1 according to Embodiment 1 of the present disclosure has a door composed of a plurality of doors. The first door is a door that rotates downward to close, and the second door is a door that rotates upward to close. When the first door opens and closes, it is provided with an interlocking means for interlocking the second door. When the door is in the open state, the first door is configured to be located directly above the upper surface of the housing. In the open state of the door, when a force acting in the closing direction is applied to the first door, the first door and the second door have a pattern of stopping during the closing process.

[0105] With such a configuration, when some force acts on the door 4 and it accidentally rotates in the direction of closing, accidents such as the door falling on the fingers at the opening and the user being injured can be prevented, improving safety. Also, the impact on the tableware caused by the door 4 closing all at once can be reduced. Therefore, it is possible to suppress the generation of noise and damage to the tableware due to the collision between the tableware and the tableware basket 9 or between the tableware.

[0106] In the dishwasher 1 according to Embodiment 1 of the present disclosure, when the first door and the second door are in a state of stopping during the opening or closing process, the second door forms an inclined surface upward toward the front side in a side view.

[0107] With such a configuration, when the door 4 is in a half-open state or an open state, the water dripping from the inner surface of the first door 4a or the water droplets adhering to the second door 4b can be returned to the washing tank. Therefore, there is no worry about water dripping outside the machine, and the usability of the user can be improved.

[0108] The present invention is fully described in connection with preferred embodiments with reference to the accompanying drawings, but various modifications and corrections will be apparent to those skilled in this technology. Such modifications and corrections should be understood to be included therein as long as they do not depart from the scope of the present invention defined by the appended claims.

[0109] Note that the above-described embodiments are for exemplifying the technology in the present disclosure, and thus various changes, replacements, additions, omissions, etc. can be made within the scope of the claims or their equivalents.
