Description

Technical Field

[0001] This disclosure relates to dishwashers and household appliances, and more specifically, to a dishwasher including a blind module capable of covering the opening of the door when the pop-out handle is moved to the extended position, thereby preventing the interior space of the door from being contaminated by foreign objects that may be introduced through the door opening, preventing malfunctions and damage to the actuators caused by the introduction of foreign objects, and preventing the aesthetics perceived by the user from being degraded by obstructing the observation of the interior space of the door. Background Technology

[0002] A dishwasher is a device that washes dishes and cooking utensils stored therein by spraying washing water into it. In this respect, the washing water may contain detergent.

[0003] Dishwashers typically include a tub that defines a washing space therein, a dish rack that houses the objects to be washed inside the tub, spray arms that spray washing water onto the dish rack, and a reservoir that stores water therein and supplies the washing water to the spray arms.

[0004] Using this type of dishwasher can reduce the time and effort required to wash dishes and other laundry items after meals, thus bringing convenience to users.

[0005] Typically, dishwashers are configured to perform a washing cycle for cleaning the washable object, a rinsing cycle for rinsing the washable object, and a drying cycle for drying the washed and rinsed washable object.

[0006] To store dishes inside the dishwasher before the cycle begins and to remove the washed and dried dishes after the cycle is complete, the user should open and close the door.

[0007] In this regard, doors are usually equipped with handles that users can grip, serving as a device to facilitate opening and closing the door.

[0008] In this regard, European Patent No. 2096360 (Prior Document 001) discloses a dishwasher configured such that a pop-out handle is provided on the door, which protrudes from the front surface of the door during the gripping process for opening and closing the door.

[0009] Existing technical documents

[0010] Patent documents

[0011] (Patent Document 001) European Patent No. 2096360 Summary of the Invention

[0012] The handle disclosed in the aforementioned prior art document 001 is configured to: manually protrude from a non-use position toward a use position, wherein the amount of protrusion of the handle from the door is minimized in the non-use position, and wherein the handle can be gripped by the user while rotating in the use position.

[0013] Therefore, the handle disclosed in existing document 001 requires the user to manually move it from the non-use position to the use position, and the user must manually move it from the use position to the non-use position again when the door is opened and closed, which may cause inconvenience to the user.

[0014] Furthermore, the handle disclosed in prior art 001 remains protruding and fixed in the use position once it protrudes to the use position, unless the user performs an operation to move it back to the non-use position.

[0015] Therefore, there is a problem with the handle disclosed in existing document 001, in that the advantages of the pop-up handle are halved because the handle is always kept in a state that is substantially the same as the protruding handle.

[0016] Furthermore, when the handle disclosed in prior art 001 protrudes to the use position, the interior space of the door, which is hidden when the handle is positioned in the non-use position, can be at least partially exposed to the outside.

[0017] Therefore, the handle disclosed in prior art document 001 has a structure in which, when the handle is moved to the use position, external foreign objects such as dust may be introduced and accumulate through the exposed part of the handle, which may lead to hygiene problems.

[0018] Furthermore, when the handle disclosed in prior art 001 is moved to the use position, the opening having a considerably large cross-sectional area corresponding to the size of the handle may be exposed to the outside, so that a large external object may be introduced into the door, and thus, it is very likely to damage the components arranged inside the door.

[0019] Furthermore, when the handle disclosed in prior art 001 is moved to the use position, the opening having a considerably large cross-sectional area corresponding to the size of the handle may be exposed to the outside, allowing the user to see the interior space of the door, which may reduce the aesthetic appearance perceived by the user.

[0020] This disclosure aims to address these problems in the prior art, and a primary objective of this disclosure is to provide a dishwasher and household appliance in which a handle is configured to automatically protrude and move forward from the door only when necessary (e.g., when the door is opened and closed) to prevent external foreign objects such as dust from being introduced into the door, thereby preventing contamination of the interior space of the door and greatly improving user convenience.

[0021] Furthermore, a second object of this disclosure is to provide a dishwasher that includes a blind module capable of covering the door opening (which is opened when the pop-out handle is moved to the extended position), thereby preventing the interior space of the door from being contaminated by foreign objects that can be introduced through the door opening, preventing drive malfunction and damage to the drive due to the introduction of the foreign objects, and preventing the aesthetic experience perceived by the user from being deteriorated by blocking the observation of the interior space of the door.

[0022] Furthermore, a third object of this disclosure is to provide a dishwasher in which the front surface of the blind module for covering the door opening is formed to have an integral feel with the front surface of the door, thereby further enhancing the aesthetic experience perceived by the user.

[0023] Furthermore, a fourth object of this disclosure is to provide a dishwasher in which a handle actuator for moving the door between a retracted position and an extended position is configured to include a single drive motor, thereby reducing the space occupied by the handle actuator and improving the space utilization of the interior space for the door.

[0024] Furthermore, a fifth object of this disclosure is to provide a dishwasher in which the handle driver is configured to include a position deviation adjuster for adjusting the amount of motion deviation between the two ends of the handle (which may occur when the handle driver uses a single drive motor to drive the handle), thereby preventing damage to the handle and increased load on the drive motor due to the occurrence of the position deviation.

[0025] The purpose of this disclosure is not limited to the objectives described above, and other objectives and advantages not mentioned in this disclosure may be understood from the following description, and will become clearer from the embodiments of this disclosure. Furthermore, it will be readily apparent that the objectives and advantages of this disclosure can be achieved by the means and combinations thereof indicated in the claims.

[0026] One aspect of this disclosure provides a dishwasher comprising: a tub defining a washing space having an open front surface therein; a door configured to open and close the open front surface of the tub; a handle configured to move horizontally back and forth between an extended position in which the handle projects forward from the door and a retracted position in which the handle is at least partially received in the door; a handle actuator disposed inside the door and configured to move the handle horizontally from the retracted position toward the extended position, or from the extended position toward the retracted position; and a blind module configured to cover an opening defined by the door to allow the handle to pass through when the handle has been moved to the extended position, wherein the blind module is configured to cover the opening while moving forward in association with the movement of the handle.

[0029] According to some embodiments of the dishwasher, the spring is in a state of maximum compression when the aforementioned blind panel has been moved horizontally to the rearmost position.

[0030] According to some embodiments of the dishwasher, when the blind panel has been moved horizontally to the rearmost position, the blind panel remains in close contact with the first handle body.

[0031] According to some embodiments of the dishwasher, when the handle begins to move from the retracted position toward the extended position, the blind panel, together with the first handle body, moves horizontally forward from the rearmost position due to the restoring force of the spring.

[0032] According to some embodiments of the dishwasher, after the handle begins to move from the retracted position toward the extended position, the opening is partially opened as the first handle body passes through the opening and protrudes fully outward from the door, and the blind panel moves horizontally to the foremost position under the restoring force of the spring, thereby closing the partially opened opening.

[0033] According to some embodiments of the dishwasher, the spring is in a state of minimum compression when the blind panel has been moved horizontally to the foremost position.

[0034] According to some embodiments of the dishwasher, when the blind panel has been moved horizontally to the foremost position, the blind panel separates from the first handle body.

[0035] According to some embodiments of the dishwasher, when the blind panel has been moved to the foremost position, the front surface of the blind panel stops, while forming a continuous surface with the front surface of the door.

[0036] According to some embodiments of the dishwasher, when the blind panel has been moved to the foremost position, the front surface of the blind panel stops at a position protruding from the front surface of the door.

[0037] According to some embodiments of the dishwasher, the blind panel is connected to the bracket such that the spacing between them in the front-to-back direction is variable.

[0038] According to some embodiments of the dishwasher, the blind panel includes a first protrusion formed to project toward the support, wherein the support includes a second protrusion formed to project toward the blind panel, wherein the first protrusion and the second protrusion are telescopically connected to each other.

[0043] The dishwasher according to this disclosure can be configured such that the handle automatically protrudes and moves forward from the door only when necessary (e.g., when opening and closing the door) to prevent external foreign objects such as dust from being introduced into the door, thereby preventing contamination of the interior space of the door and greatly improving user convenience.

[0044] Furthermore, the dishwasher according to this disclosure may configure the handle driver for moving the door between the retracted position and the extended position to include a single drive motor, thereby reducing the space occupied by the handle driver and improving the space utilization of the door's interior space.

[0045] Furthermore, the dishwasher according to this disclosure may include a position deviation adjuster for adjusting the amount of motion deviation between the two ends of the handle (which may occur when the handle driver uses a single drive motor to drive the handle), thereby preventing damage to the handle and increased load on the drive motor due to the occurrence of the position deviation.

[0046] Furthermore, the dishwasher according to this disclosure may include the blind module capable of covering the opening of the door (which is opened when the pop-out handle is moved to the extended position), thereby preventing the interior space of the door from being contaminated by foreign objects that may be introduced through the opening of the door.

[0047] Furthermore, the dishwasher according to this disclosure may include the blind module capable of covering the opening of the door (which is opened when the door pop-out handle is moved to the extended position), thereby preventing the actuator from malfunctioning and being damaged by the introduction of the foreign object.

[0048] Furthermore, the dishwasher according to this disclosure may include a blind module capable of covering the opening of the door (when the door pop-out handle is moved to the extended position, the door is opened), thereby preventing the aesthetic experience perceived by the user from being deteriorated by blocking the observation of the interior space of the door.

[0049] Furthermore, the dishwasher according to this disclosure can form the front surface of the blind module for covering the opening of the door, so as to have a sense of unity with the front surface of the door, thereby further improving the aesthetic experience perceived by the user.

[0050] In addition to the effects described above, specific effects of this disclosure will also be described in conjunction with the description of the specific matters used to implement this disclosure. Attached Figure Description

[0078] [Overall structure of the dishwasher]

[0079] In the following, the overall structure of the dishwasher 1 according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0080] Figure 1 This shows a front perspective view of the dishwasher 1 according to the present disclosure. Figure 2 This is a simplified cross-sectional view showing the internal structure of the dishwasher 1 according to the present disclosure.

[0081] like Figure 1 and Figure 2 As shown, the dishwasher 1 according to this disclosure may include a housing 10 that forms the exterior.

[0082] Furthermore, the dishwasher 1 according to this disclosure may include a tub 20 installed inside the housing 10, which defines a washing space 21 for washing a target therein and has an open front surface.

[0083] Furthermore, the dishwasher 1 according to this disclosure may include a door 30 for opening / closing the open front surface of the tub 20.

[0084] Furthermore, the dishwasher 1 according to this disclosure may include a drive 40 located below the tub 20 to supply, collect, circulate, and discharge washing water for cleaning the washing target.

[0085] Furthermore, the dishwasher 1 according to this disclosure may include a dish rack 50, which is detachably arranged in the internal washing space 21 of the tub 20 and on which washing objects are placed.

[0086] Furthermore, the dishwasher 1 according to this disclosure may include a water sprayer 60, which is mounted adjacent to the dish rack 50 to spray washing water thereon for cleaning the washing target.

[0087] In this regard, for example, the objects to be washed on the cutlery shelf 50 can be cutlery such as bowls, plates, spoons, and chopsticks, as well as other cooking utensils. In the following text, unless otherwise stated, the objects to be washed will be referred to as cutlery.

[0088] The tub 20 can be formed as a box with a fully open front surface, and corresponds to the configuration of a so-called washing tank.

[0089] The washing space 21 can be confined inside the tub 20. The open front surface of the tub 20 can be opened / closed by the door 30.

[0090] Bucket 20 can be formed by pressing a heat-resistant and moisture-proof metal sheet (e.g., stainless steel sheet).

[0091] In addition, multiple supports may be arranged on the inner surface of the bucket 20 for the purpose of installing functional components such as the cutlery shelf 50 and the water sprayer 60, which will be described later, inside the bucket 20.

[0092] In one example, the drive 40 may include a storage tank 41 in which washing water is stored.

[0093] In addition, the drive 40 may include a tank cover 42 that separates the tank 41 from the bucket 20.

[0094] In addition, the drive 40 may include a water supply device 43 that supplies washing water from an external source to the storage tank 41.

[0095] In addition, the drive 40 may include a drain 44 that discharges the washing water from the storage tank 41 to the outside.

[0096] In addition, the drive 40 may include a wash pump 45 and a supply flow path 46 for supplying wash water from the reservoir 41 to the sprayer.

[0097] The tank cover 42 can be placed on top of the tank 41 and can be used to distinguish the bucket 20 and the tank 41 from each other.

[0098] In addition, the storage tank cover 42 may have a plurality of collection holes defined therein for collecting washing water sprayed into the washing space 21 by the water sprayer 60 into the storage tank 41.

[0099] In other words, the washing water sprayed from the sprayer toward the dishes may fall to the bottom of the washing space 21 and can be collected again through the storage tank cover 42 and enter the storage tank 41.

[0100] The washing pump 45 can be arranged on one side of the storage tank 41 and can be used to pressurize the washing water and supply the pressurized washing water to the sprayer 60.

[0101] One end of the washing pump 45 can be connected to the storage tank 41, and the other end can be connected to the supply flow path 46. The washing pump 45 may include an impeller 451 and a motor 453. When the motor 453 is powered, the impeller 451 can rotate, so the washing water in the storage tank 41 can be pressurized and then supplied to the sprayer through the supply flow path 46.

[0102] Although not shown, the wash pump 45 may include a wash water heater for heating the supplied wash water during a wash cycle or a hot rinse cycle.

[0103] In one example, supply path 46 can be used to selectively supply washing water from washing pump 45 to sprayer 60.

[0104] For example, supply flow path 46 may include a first supply flow path 461 connected to the lower injection arm 61 and a second supply flow path 463 connected to the upper injection arm 62 and the top nozzle 63.

[0105] The supply path 46 may be equipped with a supply path switching valve 465, which selectively opens / closes the supply paths 461 and 463.

[0106] In this regard, the supply flow path switching valve 465 can be controlled to open supply flow paths 461 and 463 sequentially or simultaneously.

[0107] In one example, the sprayer 60 can be configured to spray washing water onto the tableware stored on the tableware shelf 50.

[0108] More specifically, the water sprayer 60 may include a lower spray arm 61 located at the lower portion of the tub 20 to spray washing water onto the lower shelf 51.

[0109] In addition, the water sprayer 60 may include an upper spray arm 62 located between the lower shelf 51 and the upper shelf 52 to spray washing water onto the lower shelf 51 and the upper shelf 52.

[0110] In addition, the sprayer 60 may include a top nozzle 63 located on top of the tub 20 to spray washing water onto the top shelf 53 or the upper shelf 52.

[0111] Specifically, the lower spray arm 61 and the upper spray arm 62 can be rotatably arranged in the washing space 21 of the tub 20, and can spray washing water toward the tableware on the dish rack 50 while rotating.

[0112] The lower spray arm 61 can be rotatably supported above the tank cover 42 so as to spray washing water toward the lower shelf 51 while rotating and being arranged below the lower shelf 51.

[0113] In addition, the upper spray arm 62 can be rotatably supported by the spray arm holder 467 so as to spray washing water onto the dishes while rotating and being arranged between the lower shelf 51 and the upper shelf 52.

[0114] In one example, although not shown, in order to improve washing efficiency, an additional device may be provided at the lower surface 25 of the tub 20 for transferring the washing water sprayed from the lower spray arm 61 to the upward direction (along the U direction).

[0115] The detailed configuration of the water sprayer 60 is known in the art. Therefore, a description of the specific configuration of the water sprayer 60 will be omitted below.

[0116] A cutlery shelf 50 for storing cutlery can be arranged in the washing space 21.

[0117] The cutlery shelf 50 can be configured to extend from or retract into the interior space of the bucket 20 through the open front surface of the bucket 20.

[0118] For example, in Figure 2The present invention illustrates one embodiment in which the cutlery rack includes: a lower shelf 51 located at the lower portion of the tub 20 for accommodating relatively large cutlery; an upper shelf 52 located on top of the lower shelf 51 for accommodating medium-sized cutlery; and a top shelf 53 located at the top level of the tub 20 and capable of storing small cutlery, etc. However, embodiments of the present disclosure are not limited thereto. However, an example in which the dishwasher 1 includes three cutlery racks 50 as shown in the figure is described below.

[0119] Each of the lower shelf 51, the upper shelf 52, and the top shelf 53 can be configured to extend to the outside through the open front surface of the barrel 20.

[0120] For this purpose, guide rails (not shown) can be arranged on two opposing inner sidewalls that form the inner surface of the barrel 20. For example, the guide rails may include an upper guide rail, a lower guide rail, and a top guide rail.

[0121] Wheels can be arranged on the bottom of each of the lower shelf 51, upper shelf 52, and top shelf 53. The user can extend the lower shelf 51, upper shelf 52, and top shelf 53 to the outside through the open front surface of the bucket 20, and can place tableware on them or easily remove washed tableware.

[0122] The guide rail (not shown) can be embodied as a simple track-type fixed guide rail to guide the extension or retraction of the shelf 50, or it can be embodied as a telescopic guide rail capable of guiding the extension or retraction of the shelf 50, and simultaneously increasing its extension distance as the shelf 50 extends further from the interior space of the barrel.

[0123] In one example, door 30 is configured to open / close the open front surface of barrel 20 as described above.

[0124] The hinge (not shown) around which the door 30 is closed or opened can typically be located at the bottom of the front surface of the opening. Thus, the door 30 can be opened by pivoting around the hinge, which serves as the pivot axis.

[0125] In this respect, a handle 31 for opening the door 30 and a control panel 32 for controlling the operation of the dishwasher 1 can be arranged on the outer surface of the door 30.

[0126] As shown in the figure, the control panel 32 may include: a display 33, which visually displays information such as the current operating status of the dishwasher 1; and a button unit 34, which includes a selection button and a power button. The selection button is used to input the user's program selection operation, and the power button is used to input the user's operation to start and stop the dishwasher.

[0127] In one example, the rear panel that forms the inner surface of the door 30 can form a surface of the bucket 20 when the door 30 is closed, and can form a mounting surface of the lower shelf 51 on which the cutlery shelf 50 is supported when the door 30 is fully open.

[0128] Therefore, when the door 30 is fully opened downwards, the rear panel of the door 30 can form a horizontal plane that extends in the same direction as the guide rail that guides the displacement of the lower shelf 51.

[0129] In one example, unlike a conventional handle, the handle 31 of the dishwasher 1 according to this disclosure can be configured such that when the handle is not in use, it is at least partially housed inside the door 30, and when the door 30 needs to be opened and closed, it can automatically extend from the door 30 in a forward-projecting manner.

[0130] Since the handle is configured to retract so as to be at least partially accommodated inside the door 30, or to extend outside the door 30 in a forward-projecting manner, the handle 31 can be referred to by various names such as pop-out handle, retractable handle, extendable handle, etc.

[0131] In the following text, according to one embodiment of the invention, a handle 31 configured to retract into or extend from the door 30 of the dishwasher 1 will be referred to as a pop-out handle 31.

[0132] Please refer to later Figure 3 The detailed configuration of the pop-up handle 31 is described in the accompanying diagrams.

[0133] Although not shown, the rear panel defining the interior of the door 30 may also be provided with a detergent supply device for automatically supplying detergent into the interior of the drum 20.

[0134] Furthermore, the door position sensor 36 can be disposed on the outer top surface of the barrel 20 and can be configured to detect whether the door 30 is in a closed or open state. For example, the door position sensor 36 may include a door position sensor S_d or a latch sensor that detects the position of a latch (not shown).

[0135] In one example, a dry air supply device 80 may be arranged at the lower part of the tub 20 and may be configured to generate high-temperature or low-temperature dry air and supply it to the washing space 21 inside the tub 20.

[0136] As shown in the figure, the dry air supply device 80 can be configured to include a filter element 883 for filtering external air, a blower 825 for generating a dry airflow, a heater 84 for heating the dry airflow, and an airflow guide 83 arranged inside the barrel 20 to guide the dry airflow.

[0137] The dry air supply port can be defined in the lower surface of the barrel 20, so that the high-temperature dry air generated by the dry air supply device 80 can be introduced into the interior of the barrel 20 through the dry air supply port.

[0138] Therefore, during the drying cycle, high-temperature or low-temperature drying air can be supplied from the drying air supply device 80 to the interior of the drum 20, thereby significantly improving the drying efficiency and sterilization effect of tableware compared to conventional dishwashers.

[0139] In one example, the dishwasher can be configured such that airflow supplied to the interior of the tub 20 and humidified while drying the dishes can be discharged to the outside, and the discharge of the airflow can be achieved via a partial opening of the door 30 or via a separate air discharge device (not shown).

[0140] [Appearance and operation of the pop-up controller]

[0141] In the following text, refer to Figures 3 to 5b The appearance and operation of the pop-out handle 31 arranged at the door 30 of a dishwasher 1 according to one embodiment of the present disclosure will be described in detail.

[0142] In the following description, one embodiment will be used as an example, wherein, as an example, the pop-out handle 31 and related components of the pop-out handle 31 are arranged inside the door 30 that constitutes the dishwasher 1.

[0143] However, this disclosure is not limited thereto. Furthermore, the pop-out handle 31 and related components of the pop-out handle 31, which will be described later, can be similarly applied to household appliances such as ovens, refrigerators, dryers, washing machines, or laundry management devices, which are configured such that the interior space of the housing performing a specific function can be opened and closed through a door.

[0144] However, such ovens, refrigerators, dryers, washing machines, or laundry management devices are configured to operate under different operating conditions and environments, having different purposes and functions than the dishwasher 1 according to this disclosure.

[0145] Specifically, since the oven operates at high temperatures, the pop-out handle and handle actuator should be made of materials capable of withstanding high temperatures. Furthermore, while the oven door provides sufficient space for the pop-out handle and handle actuator, the use of partially heat-resistant glass necessitates that the pop-out handle and handle actuator be compatible with the glass material. Additionally, a means to ensure durability and safety in high-temperature environments should be added.

[0146] In one example, in a refrigerator, the interior of the door includes shelves, storage space, insulation, etc., which can limit space utilization.

[0147] Therefore, installing the pop-out handle and handle actuator may require redesigning the door's internal structure or ensuring a space that allows for installation without interfering with the existing structure. Furthermore, in the case of refrigerators, where the pop-out handle is located within a door that is frequently opened and closed, durability and water resistance may be essential.

[0148] With this in mind, the motor or electronic components driving the pop-out handle can be housed in the empty space confined within the refrigerator door and need to be designed to be compatible with the refrigerator's power supply. However, a design may be needed to prevent interference with the door's internal insulation and shelving structure, and a method that takes into account waterproofing and durability could be added.

[0149] In one example, the dryer is exposed to a high-temperature and humid environment. The pop-out handle and handle actuator should be made of materials that can withstand high temperatures, and a means of preventing internal heat damage to the dryer is required.

[0150] In one example, in the case of a washing machine, a tub for holding water, detergent, and laundry is located at the rear of the door. Therefore, when the pop-out handle and handle actuator are installed in the washing machine door, a waterproof and dustproof design is likely essential due to the high likelihood of exposure to water and detergent. Specifically, the handle actuator should be installed in a sealed space so that the motor or electronic components are not exposed to water, and a means to enhance durability through a waterproof and dustproof design is required.

[0151] In one example, because the laundry management unit includes a steam function, moisture may seep into the door. Therefore, the pop-out handle and handle actuator should be moisture-proof and designed as a sealed structure to prevent water penetration. Thus, additional waterproof and moisture-proof measures are needed to ensure durability in a steam environment.

[0152] Given the operating environment and conditions, since washing machines, setting machines, and dryers are highly likely to be exposed to water and moisture, a sealing structure may be essential for the pop-up handle and handle actuator.

[0153] In addition, since dryers and ovens need to operate in high-temperature environments, their pop-out handles and handle actuators should be made of heat-resistant materials.

[0154] Furthermore, the motor or electronic components of the drive handle should be arranged to make efficient use of the door's internal space and should be designed to avoid inconvenience to the user. Additionally, the pop-out handle and drive handle need to be equipped with safety and injury prevention devices for the user, and also with a mechanism to allow the user to manually open the door even in the event of a malfunction.

[0155] Specifically, in the following description, the pop-out handle 31 will be arranged to extend parallel to the top surface of the door 30 in the left-right direction, taking into account the opening and closing direction of the dishwasher 1 door 30. However, in the case of different household appliances (e.g., refrigerators and laundry management devices) to which the opening and closing direction of the door 30 is applied, the pop-out handle 31 may be arranged in the door such that the longitudinal direction of the pop-out handle 31 is parallel to the vertical direction.

[0156] As described above, the pop-out handle 31 can be arranged in the door 30 of the dishwasher 1 according to an embodiment of the present disclosure so as to move back and forth in the front-to-back direction.

[0157] In this respect, as described above, door 30 can be configured to pivot about a hinge (not shown) attached to the lower end of the door.

[0158] However, this disclosure is not limited thereto, and drawer doors configured to open and close in a simple horizontal movement along the front-to-back direction (FR direction) are also applicable. In the following description, as illustrated, an embodiment will be based on which the door 30 opens and closes while pivoting about a hinge connected to its lower end.

[0159] Taking this into consideration, such as Figure 3 and Figure 4 As shown, the pop-out handle 31 can be positioned as close as possible to the top surface of the door 30, where the user can easily grip the handle.

[0160] Furthermore, the pop-out handle 31 can be arranged to extend and retract via the front panel 30a that passes through the front surface of the door 30.

[0161] In addition, the pop-out handle 31 can be arranged parallel to the top surface of the door 30 in the left-right direction for easy gripping by the user.

[0162] Furthermore, the pop-out handle 31 can be configured to typically have The shape is designed for easy gripping by users.

[0163] Alternatively, when the pop-out handle 31 is formed as a simple rod that completely fills the opening 30e of the front panel 30a, the blind module 37, which will be described later, is not necessary, but this may cause some inconvenience when the user grips the handle for opening the door 30.

[0164] Therefore, it includes the leg area connected to the door 30 and the gripping area for the user to hold. The shape is adapted to the pop-out handle 31, allowing the user to easily grip the pop-out handle 31 by applying force to fully surround it and open the door 30.

[0165] Therefore, the pop-out handle 31 can have a through area defined by a shape surrounded by a leg area and a gripping area. Thus, as will be described later, due to the through area of ​​the pop-out handle 31 and the opening 30e of the front panel 30a of the door 30, the internal structure of the door 30 is inevitably exposed to the outside. (Referring later...) Figure 8 The following figures describe the detailed configuration of the blind module 37 used to cover the opening 30e.

[0166] More specifically, such as Figure 5b As illustrated in the example, in order to form In terms of appearance, the pop-out handle 31 may include a first handle body 3111, which protrudes completely outside the door 30 when the pop-out handle 31 moves forward and becomes a gripping area that can be grasped by the user.

[0167] In addition, the pop-out handle 31 may also include a second handle body 3112 connected to the left end of the first handle body 3111, which extends rearward and becomes a support leg area.

[0168] In addition, the pop-out handle 31 may also include a third handle body 3113 connected to the right end of the first handle body 3111, which extends rearward and becomes a support leg area.

[0169] In this respect, when the pop-out handle 31 moves forward, the second handle body 3112 and the third handle body 3113 can partially protrude outside the door 30.

[0170] Therefore, based on the illustrated embodiment, the through area surrounded by the first handle body 3111, the second handle body 3112, the third handle body 3113 and the front panel 30a of the door 30 can be defined in the vertical direction, and the user can place his / her fingers in the through area when opening the door 30 to grasp the first handle body 3111 and pull it.

[0171] However, as described above, when the pop-out handle 31 is pointed into the door so that its longitudinal direction is parallel to the vertical direction (UD direction), the through area can be defined along the left and right directions.

[0172] In other words, the pop-out handle 31 can be placed in any area and point in any direction, including the diagonal direction of the door 30.

[0173] In the illustrated embodiment, the second handle body 3112 and the third handle body 3113 are formed separately and are forcibly fastened to both ends of the first handle body 3111 by separate fastening devices (e.g., bolts, etc.), but they can be integrally formed with the first handle body 3111.

[0174] The guide block 3114 can be arranged on the left side surface of the second handle body 3112 and the right side surface of the third handle body 3113, respectively.

[0175] The guide block 3114 is inserted into the guide brackets 30h1 and 30h2 of the handle frame 30d, which will be described later, and is used to guide the back-and-forth reciprocating movement of the handle frame 30d.

[0176] In addition, the guide block 3114 can be used as a stop to prevent the pop-out handle 31 from moving further forward after it has completed its movement to the extended position Pd.

[0177] In addition, after the pop-out handle 31 moves to the extended position Pd, the guide block 3114 can also be used to absorb the force or impact exerted by the user on the second handle body 3112 and the third handle body 3113 of the pop-out handle 31 to open the door 30.

[0178] With this in mind, the guide block 3114 can be made of an elastic material with predetermined elasticity.

[0179] In order to extend and retract the pop-out handle 31, an opening 30e with a rectangular shape corresponding to the appearance of the pop-out handle 31 can be defined by passing through the front panel 30a of the door 30 in the front-rear direction (FR direction).

[0180] As will be described later, the pop-out handle 31 can be configured to reciprocate in the forward and backward (FR) direction through the opening 30e of the front panel 30a under the operation of the handle driver 35.

[0181] More specifically, the pop-out handle 31 can be arranged to move back and forth in the front-rear direction between the foremost position and the rearmost position under the operation of the handle driver 35.

[0182] For convenience, the forwardmost position of the ejector handle 31 is defined as the extended position Pd. The rearmost position of the ejector handle 31 is defined as the retracted position Pa.

[0183] Figure 3 This illustrates a state where the pop-up handle 31 has moved to the rearmost position (i.e., the retracted position Pa) and thus retracted into the interior of the door 30.

[0184] As shown in the figure, when the pop-out handle 31 has moved to the retracted position Pa, the pop-out handle 31 can be in a state where it is fully or partially retracted into the interior of the door 30.

[0185] In this respect, exemplarily, the pop-out handle 31 can pass through the entire opening 30e of the door 30 and retract into the interior of the door 30.

[0186] Furthermore, when the pop-out handle 31 has moved to the retracted position Pa, the pop-out handle 31 can be in a state in which the pop-out handle 31 does not protrude from the front panel 30a of the door 30 in the forward direction.

[0187] Furthermore, when the pop-out handle 31 has moved to the retracted position Pa, the front surface of the pop-out handle 31 can be coplanar with the front surface of the front panel 30a of the door 30, thereby forming a continuous surface.

[0188] In other words, the front surface of the pop-out handle 31 can be parallel to the front panel 30a when it is in the retracted position Pa.

[0189] Therefore, a state in which no step is formed between the front surface of the front panel 30a of the door 30 and the front end surface of the pop-out handle 31 can be formed.

[0190] Therefore, when the pop-out handle 31 has moved to the retracted position Pa, the opening 30e of the front panel 30a may be completely blocked.

[0191] Furthermore, when the pop-out handle 31 has moved to the retracted position Pa, no step is formed between the front surface of the front panel 30a and the front end surface of the pop-out handle 31, thereby fundamentally preventing the accumulation of foreign matter such as dust on the protrusions formed on the front surface of the door 30 or on the handle itself, as in conventional methods.

[0192] In one example, such as Figure 5b As shown, the front surface of the pop-out handle 31 can be the front surface of the decorative panel 315, which is separately disposed from the first handle body 3111, the second handle body 3112 and the third handle body 3113 that constitute the appearance of the pop-out handle 31.

[0193] In this respect, the front surface of the decorative panel 315 may include a material with the same texture and color as the front panel 30a of the door 30.

[0194] Therefore, a sense of unity can be created between the decorative panel 315 and the front panel 30a of the door 30.

[0195] In addition, it can improve the aesthetic appearance of the door 30 and enhance the aesthetic perception of the door by the user.

[0196] Figure 4 and Figure 5a This example illustrates the state in which the pop-up handle 31 has moved from the retracted position Pa to the extended position Pd, which is the foremost position.

[0197] The door 30 of dishwasher 1 should be opened and closed to store dishes that need to be washed in the dishwasher or to remove dishes that have already been washed in dishwasher 1.

[0198] When the user's intention to open the door 30 is recognized when it is necessary to open / close the door 30, the pop-up handle 31 can automatically move from the retracted position Pa to the extended position Pd under the operation of the handle driver 35.

[0199] Therefore, the dishwasher 1 according to the present disclosure may also be provided with a device for detecting the user's intention to open the door 30.

[0200] For example, a device for detecting a user’s intention to open door 30 may include a proximity sensor (not shown).

[0201] A proximity sensor can be a sensor that can detect whether a user is close enough to be within a specific range of 30 degrees from a door.

[0202] For example, proximity sensors may include any of the following: radar sensors, image sensors, or infrared (IR) sensors.

[0203] In order to effectively identify whether a user is nearby, a proximity sensor can be arranged on at least one of the top surface, bottom surface and front surface of the door 30.

[0204] In addition, the device for detecting the user's intention to open the door 30 may include a touch sensor (not shown).

[0205] By way of example, a touch sensor may include any of the following: capacitive, resistive, and pressure-type touch sensors.

[0206] A touch sensor can be arranged in the pop-out handle 31 to effectively recognize the intention to open or close the door 30.

[0207] Example: The touch sensor may be mounted on the handle base plate 313 together with the lighting element, which will be described later.

[0208] like Figure 4 and Figure 5a As shown, when the user's intent is recognized, the pop-up handle 31 can automatically move forward to the extended position Pd.

[0209] When the pop-out handle 31 is moved to the extended position Pd as described above, a state can be formed in which the first handle body 3111 of the pop-out handle 31 is completely exposed to the outside of the door 30.

[0210] Furthermore, once the pop-up handle 31 has moved to the extended position Pd, a state in which the user can grip the handle can be created.

[0211] In this respect, the stroke Ls of the pop-out handle 31 from the retracted position Pa to the extended position Pd can, for example, be equal to or greater than 40 mm and equal to or less than 50 mm.

[0212] Preferably, the stroke Ls of the pop-out handle 31 from the retracted position Pa to the extended position Pd can be 45 mm.

[0213] The stroke Ls of the pop-out handle 31 is determined in this way because if the stroke Ls is too small (e.g., less than 40 mm), it will be difficult for the user to grip the pop-out handle 31, while if the stroke Ls is too large (e.g., more than 50 mm), the size of the pop-out handle 31 in the front-back direction will increase, so that the pop-out handle 31 cannot be fully retracted into the door 30.

[0214] However, the travel Ls of the pop-out handle 31 is only an example and can be set differently depending on the overall size of the dishwasher 1 and the size of the door 30 in the front-to-back direction.

[0215] In one example, when the pop-out handle 31 moves to the extended position Pd, the first handle body 3111 of the pop-out handle 31 can leave the opening 30e of the front panel 30a of the door 30 and be fully exposed and protruding to the outside of the door 30.

[0216] Therefore, the closed state of the opening 30e of the front panel 30a is released at least partially by the pop-out handle 31.

[0217] However, as will be described later, when the pop-out handle 31 is moved to the extended position Pd, the blind panel 371 of the blind module 37 moves forward together with the first handle body 3111 in association.

[0218] Therefore, the opening 30e of the front panel 30a, which opens based on the movement of the pop-out handle 31, can be covered by the blind module 37.

[0219] Therefore, even when the pop-out handle 31 is moved to the extended position Pd, the opening 30e of the front panel 30a can remain closed or covered.

[0220] Therefore, it can effectively prevent foreign objects such as dust from passing through the opening 30e and being introduced into the door 30.

[0221] Furthermore, it is impossible to observe the interior of the door 30 through the opening 30e of the front panel 30a due to the blind module 37.

[0222] Therefore, it can effectively prevent the aesthetic degradation of the door as perceived by the user.

[0223] Please refer to later Figures 8 to 15 The description includes a detailed configuration of the blind module 37 of the blind panel 371.

[0224] In one example, the pop-out handle 31 of the dishwasher 1 according to an embodiment of the present disclosure can be configured to allow the user to visually recognize that the pop-out handle 31 is being driven normally.

[0225] For example, such as Figure 5b As illustrated, a device for visual recognition may include a handle base plate 313 disposed in front of a first handle body 3111, and at least one illumination element mounted thereon.

[0226] In addition, the device for visual recognition may include a light guide plate 314, which is arranged in front of the handle substrate 313 and diffuses the visible light L generated from the illumination element.

[0227] As illustrated, the handle base plate 313 and the light guide plate 314 can be arranged between the decorative panel 315 and the first handle body 3111.

[0228] Although not shown, the lighting element can be used without limitation, as long as it is a device capable of receiving electricity and generating a predetermined visible light L, and can be exemplarily an LED element.

[0229] The light guide plate 314 is used to diffuse the visible light L generated from the lighting element.

[0230] More specifically, the visible light L generated from the lighting element 3131 can be introduced into the front or rear surface of the light guide plate 314, then uniformly dispersed within the light guide plate 314, and then diffused toward the outer edge of the light guide plate 314.

[0231] In this regard, as described above, the decorative panel 315 arranged in front of the light guide plate 314 is surface treated to have the same texture as the front panel 30a of the door 30.

[0232] Therefore, the visible light L introduced into the light guide plate 314 can pass through the decorative panel 315 and can be projected to the outside through the outer edge of the light guide plate 314.

[0233] In order to project visible light L to the outside, such as Figure 5aAs shown, the edge of the light guide plate 314 can be exposed to the outside.

[0234] In other words, the light guide plate 314 is arranged in a state where it is sandwiched between the decorative panel 315 and the front surface of the first handle body 3111.

[0235] In this respect, the outer edges of the light guide plates 314 can be arranged to be uncovered.

[0236] Therefore, as illustrated, the visible light L generated from the lighting element 3131 can be effectively projected to the outside through the outer edge of the light guide plate 314 via the interior of the light guide plate 314.

[0237] Therefore, the user can effectively check whether the pop-up handle 31 is in operation and its operating status, wherein visible light L is projected through the outer edge of the light guide plate 314.

[0238] Furthermore, since visible light L is projected only through the outer edge of the light guide plate 314, an illumination effect similar to indirect light can be achieved. Therefore, the aesthetic appeal perceived by the user can be enhanced.

[0239] [Detailed configuration of the gamepad driver and gamepad frame]

[0240] In the following text, reference will be made to Figures 6 to 17 The detailed configuration of the handle driver 35 is described, which drives the pop-up handle 31 to reciprocate back and forth between the extended position Pd and the retracted position Pa.

[0241] First, refer to Figures 6 to 8 The handle driver 35 may include a drive motor 351 that receives power and generates rotational driving force.

[0242] In this respect, as described above, the drive motor 351 that constitutes the handle driver 35 can be configured as a single unit.

[0243] Therefore, the rotational driving force provided to the left end and the right end of the pop-out handle 31 can be generated by the drive motor 351.

[0244] As described above, since the handle driver 35 is configured to include only a single drive motor 351, the number of components constituting the dishwasher 1 can be reduced.

[0245] In addition, the space occupied by the handle driver 35 inside the door 30 can be effectively reduced, thereby improving the space utilization rate inside the door 30.

[0246] The motor body 3511 of the drive motor 351 can be arranged at a position between the left end of the pop-out handle 31 and the right end of the handle 31 relative to the pop-out handle 31, so as to jointly generate a rotational driving force toward the left end of the pop-out handle 31 and the right end of the handle 31.

[0247] In addition, the motor body 3511 can output rotational driving force in two directions so as to generate rotational driving force together.

[0248] More specifically, as illustrated in the figure, the drive motor 351 may include a first output shaft 3512a that extends horizontally toward a second handle body 3112 that forms the left end of the pop-out handle 31.

[0249] Based on the illustrated embodiment, the first output shaft 3512a can pass through the left side surface of the motor body 3511 and extend horizontally toward the second handle body 3112.

[0250] In addition, the drive motor 351 may include a second output shaft 3512b that extends horizontally toward the third handle body 3113 that forms the right end of the pop-out handle 31.

[0251] Based on the illustrated embodiment, the second output shaft 3512b can pass through the right side surface of the motor body 3511 and extend horizontally toward the third handle body 3113.

[0252] In this regard, such as Figure 12 As illustrated, a first gap W1 can be formed between the first output shaft 3512a of the drive motor 351 and the left end of the second handle body 3112 of the pop-up handle 31 in relation to the left-right direction (Le-Ri direction).

[0253] In addition, such as Figure 12 As illustrated, a second gap W2 can be formed between the second output shaft 3512b of the drive motor 351 and the right end of the third handle body 3113 of the pop-up handle 31 in relation to the left-right direction (Le-Ri direction).

[0254] In this case, the first spacing W1 and the second spacing W2 can be equal to each other.

[0255] As will be described later, the rotational driving force of the first output shaft 3512a can be transmitted to the first lead screw 352a via the first connector 355a.

[0256] Furthermore, the rotational driving force of the second output shaft 3512b can be transmitted to the second lead screw 352a via the second connector 355b.

[0257] Since the first spacing W1 and the second spacing W2 are set to be equal to each other, a first lead screw 352a and a second lead screw 352b having the same length and shape can be used.

[0258] In other words, the first lead screw 352a and the second lead screw 352b can be arranged to be interchangeable. Therefore, the components can be used interchangeably.

[0259] As described above, the pop-out handle 31 of the dishwasher 1 according to the present disclosure can be configured to reciprocate between the extended position Pd and the retracted position Pa as forward movement from the retracted position Pa toward the extended position Pd and backward movement from the extended position Pd toward the retracted position Pa are repeatedly performed.

[0260] To easily achieve this repetitive reciprocating movement, the drive motor 351 constituting the handle driver 35 can be configured to generate bidirectional rotational driving force.

[0261] Therefore, according to embodiments of this disclosure, any type of motor capable of generating the bidirectional rotary driving force as described above can be applied, without limitation, to the handle driver 35 of the dishwasher 1, such as the drive motor 351.

[0262] In the following text, the drive performed between bidirectional rotary drive forces, rotating along the output shaft 3512 of the drive motor 351 to move the pop-up handle 31 forward toward the extended position Pd, will be referred to as forward rotary drive or forward rotary drive force.

[0263] Furthermore, the direction drive between bidirectional rotary drive forces, rotating along the output shaft 3512 of the drive motor 351 to move the pop-up handle 31 forward toward the extended position Pd, will be referred to as reverse rotary drive or reverse rotary force.

[0264] In one example, such as Figure 6 and Figure 7 As illustrated, the motor body 3511 of the drive motor 351 can be fixed inside the handle frame 30d.

[0265] More specifically, the motor body 3511 of the drive motor 351 can be forcibly connected to the rear surface of the front wall 30d11 of the frame body 30d1 of the handle frame 30d by means of a fastening device such as screws, while being housed in a motor bracket 3511a having a hollow box shape.

[0266] To prevent interference with and avoid the first output shaft 3512a and the second output shaft 3512b extending along the left-right direction (Le-Ri direction), a plurality of fastening tabs with screw holes can be integrally formed with the top and bottom surfaces of the motor bracket 3511a.

[0267] As will be described later, a plurality of first screw bosses 30d5 may be integrally formed with the rear surface of the front wall 30d11 of the frame body 30d1 to protrude from therein in accordance with the positions of a plurality of fastening tabs.

[0268] In one example, the handle driver 35 may also include a pair of lead screws 352a and 352b.

[0269] The lead screws 352a and 352b are used to transmit the rotational driving force generated from the drive motor 351 to the motion converters 353a, 354a, 353b and 354b, which will be described later.

[0270] More specifically, a pair of lead screws 352a and 352b may include a first lead screw 352b, which is connected to the first output shaft 3512a of the drive motor 351 and rotates by receiving rotational driving force from the first output shaft 3512a.

[0271] For example, the first lead screw 352a may have a cylindrical shape that extends in the left-right direction, similar to the first output shaft 3512a.

[0272] Furthermore, the first lead screw 352a can be connected to the first output shaft 3512a in a state in which it can rotate but cannot move in the front-back direction (FR direction) or the left-right direction (Le-Ri direction).

[0273] Therefore, the right end of the first lead screw 352a can be connected to the first output shaft 3512a so that it can rotate integrally with the first output shaft 3512a.

[0274] Furthermore, the left end of the first lead screw 352a can be rotatably supported by the bushing 3722 of the first bracket 372 of the blind module 37, which will be described later.

[0275] In one example, an external thread with a predetermined longitudinal width can be formed on the outer circumferential surface of the left end of the first lead screw 352a.

[0276] The first nut 353a, which constitutes the first motion converters 353a and 354a described later, can be threaded onto an external thread.

[0277] As will be described later, when the first nut 353a moves linearly in the left-right direction (Le-Ri direction) by the forward or reverse rotation of the first lead screw 352a, the rotational driving force of the first lead screw 352 can be converted by the first nut 353a into a linear driving force in the left-right direction (Le-Ri direction).

[0278] In order to ensure a predetermined margin for the linear movement range of the first nut 353a, the longitudinal width of the external thread formed on the first lead screw 352a can be slightly larger than the linear movement range of the first nut 353a in the left-right direction.

[0279] In addition, the pair of lead screws may include a second lead screw 352b, which is connected to the second output shaft 3512b of the drive motor 351 and rotates by receiving rotational driving force from the second output shaft 3512b.

[0280] For example, the second lead screw 352b may have a cylindrical shape that extends in the left-right direction, similar to the second output shaft 3512b.

[0281] Furthermore, the second lead screw 352b can be connected to the second output shaft 3512b in a state in which it can rotate but cannot move in the front-back direction (FR direction) or the left-right direction (Le-Ri direction).

[0282] For this purpose, the left end of the second lead screw 352b can be connected to the second output shaft 3512b so that it can rotate integrally with the second output shaft 3512b.

[0283] Furthermore, the right end of the second lead screw 352b can be rotatably supported by the bushing 3732 of the second bracket 373 of the blind module 37, which will be described later.

[0284] In one example, an external thread with a predetermined longitudinal width can be formed on the outer circumferential surface of the right end of the second lead screw 352b.

[0285] The second nut 353b, which constitutes the second motion converters 353b and 354b described later, can be threaded onto the external thread.

[0286] As will be described later, when the second nut 353b moves linearly in the left-right direction (Le-Ri direction) by the forward or reverse rotation of the second lead screw 352b, the rotational driving force of the second lead screw 352b can be converted by the second nut 353b into a linear driving force in the left-right direction (Le-Ri direction).

[0287] To ensure a predetermined margin for the linear movement range of the second nut 353b, the longitudinal width of the external thread formed on the second lead screw 352b can be slightly larger than the linear movement range of the second nut 353b in the left-right direction.

[0288] As described above, the first lead screw 352a and the second lead screw 352b can have the same length and shape.

[0289] Therefore, the first lead screw 352a and the second lead screw 352b can be arranged to be interchangeable. Thus, the components can be used interchangeably.

[0290] In one example, the handle driver 35 may also include a pair of connectors 355a and 355b.

[0291] More specifically, the pair of connectors 355a and 355b may include a first connector 355a that connects the first output shaft 3512a of the drive motor 351 to the first lead screw 352a, such that they rotate integrally with each other.

[0292] In addition, the pair of connectors 355a and 355b may include a second connector 355b that connects the second output shaft 3512b of the drive motor 351 to the second lead screw 352b, such that they rotate integrally with each other.

[0293] Through the first connector 355a, even when the first output shaft 3512a and the first lead screw 352a of the drive motor 351 are not arranged on the same rotating shaft, the rotational driving force of the first output shaft 3512a can be effectively transmitted to the first lead screw 352a.

[0294] Furthermore, through the second connector 355a, even when the second output shaft 3512b and the second lead screw 352b of the drive motor 351 are not arranged on the same rotating shaft, the rotational driving force of the second output shaft 3512b can be effectively transmitted to the second lead screw 352b.

[0295] In the same manner as the first lead screw 352a and the second lead screw 352b, the first connector 355a and the second connector 355b can be arranged to be interchangeable with each other.

[0296] In one example, the handle driver 35 may also include a pair of motion converters.

[0297] First, such as Figure 8 As shown, the pair of motion converters may include first motion converters 353a and 354a, which convert the rotational driving force transmitted from the first lead screw 352a into a linear driving force in the front-rear direction (FR direction).

[0298] The linear driving force in the forward / backward (FR) direction converted by the first motion converters 353a and 354a can be transmitted to the second handle body 3112 forming the left end of the pop-out handle 31.

[0299] More specifically, the first motion converters 353a and 354a may include a first nut 353a that is threaded to the external thread of the first lead screw 352a described above.

[0300] Examplely, when viewed from above, the first nut 353a may have an inverted L-shaped appearance.

[0301] The first lead screw 352a can be threadedly connected to a first component that is formed inverted L-shape and extends in the front-rear direction.

[0302] The external thread of the first lead screw 352a is connected to the internal thread, which can pass through the first component in the left-right direction.

[0303] One end of the first link 354a, which will be described later, can be rotatably connected to a second component that forms an inverted L-shape and extends to the left from the rear edge of the first component.

[0304] One end of the first connecting rod 354a can be rotatably connected to the second component of the first nut 353a via the first movable pin Pm1.

[0305] The pin insertion hole can be defined by the second part of the first nut 353a passing through it in the vertical direction (UD direction), so that the first movable pin Pm1 can be inserted into and connected thereto in the vertical direction (UD direction).

[0306] In one example, the first motion converters 353a and 354a may further include a first link 354a, which converts the linear driving force transmitted from the first nut 353a in the left-right direction (Le-Ri direction) into a linear driving force in the front-back direction (FR direction).

[0307] By way of example, the first link 354a may include a pair of links, the pair of links including a first driving link 354a1 and a first driven link 354a2.

[0308] As illustrated in the figure, one end of the first drive link 354a1 can be forked into a fork shape, while the other end can have a simple plate shape.

[0309] As described above, the forked end of the first drive link 354a1 can be rotatably connected to the second component of the first nut 353a via the first movable pin Pm1.

[0310] In one example, the other end of the first drive link 354a1, which has a simple plate shape, can be rotatably connected to the third handle body 3113 via the second movable pin Pm2.

[0311] In this respect, the upper and lower ends of the second movable pin Pm2 can be inserted into the pin guide slot 30h11 defined by the first guide bracket 30h1, which will be described later.

[0312] As will be described later, the pin guide slot 30h11 may be an elongated hole extending in the front-rear direction (FR direction) to guide the movement direction of the ejector handle 31.

[0313] Therefore, the other end of the first drive link 354a1 and the second handle body 3112 can be guided along the direction of motion by the second movable pin Pm2 and the pin guide slot 30h11 so as to move linearly along the front-rear direction (FR direction).

[0314] As illustrated in the figure, one end of the first drive link 354a1 can be forked into a fork shape, while the other end can have a simple plate shape.

[0315] In one example, the first driven link 354a2 is used to allow the rotation center of the entire first drive link 354a1 to be formed between one end and the other during the linear movement of the first nut 353a in the left-right direction (Le-Ri direction), and is used to change the rotation center of the entire first drive link 354a1.

[0316] Therefore, one end of the first driven link 354a2 can be rotatably connected to the third movable pin Pm3 located at the middle position between one end and the other end of the first driven link 354a2.

[0317] In one example, the other end of the first driven link 354a2 can be rotatably connected to the pin hole 30h13 of the first guide bracket 30h1 via a fixing pin Pf, so that the rotation center of the entire first driven link 354a2 can be changed.

[0318] Unlike the other end of the first drive link 354a1, the other end of the first driven link 354a2 is connected to the pin hole 30h13 (which is a simple round hole) via a fixing pin Pf. Therefore, the other end of the first driven link 354a2 can be connected to the interior of the first guide bracket 30h1 in a state where it can rotate but cannot move in the front-back direction (FR direction) or the left-right direction (Le-Ri direction).

[0319] To increase the connection strength with the first guide bracket 30h1, the other end of the first driven link 354a2 can be formed into a hollow cylinder.

[0320] In one example, as illustrated in the figure, the third movable pin Pm3 can be positioned closer to the first movable pin Pm1 than the second movable pin Pm2.

[0321] Therefore, relative to the third movable pin Pm3, which serves as the rotation center of the entire first drive link 354a1, the amount of rotation at the other end of the first drive link 354a1 can be greater than the amount of rotation at one end of the first drive link 354a1.

[0322] Therefore, even if the linear movement of the first nut 353a in the left-right direction (Le-Ri direction) does not increase, the stroke Ls of the second handle body 3112 in which the first drive link 354a1 pushes or pulls the pop-out handle 31 can be effectively ensured.

[0323] In one example, the pair of motion converters may include second motion converters 353b and 354b that convert the rotational driving force transmitted from the second lead screw 352b into a linear driving force in the forward-backward (FR) direction.

[0324] As described above, the first motion converters 353a and 354a and the second motion converters 353b and 354b are configured to be driven by a single drive motor 351.

[0325] Therefore, the first motion converters 353a and 354a and the second motion converters 353b and 354b can be arranged in positions symmetrical to each other relative to the vertical surface of the ejector handle 31 which is equally divided along the horizontal direction, so that the rotational driving force is equally distributed to the first motion converters 353a and 354a and the second motion converters 353b and 354b.

[0326] Furthermore, for the same reason, the first motion converters 353a and 354a and the second motion converters 353b and 354b may have shapes that are symmetrical to each other relative to the vertical surface of the pop-out handle 31 which is equally divided along the horizontal direction.

[0327] Therefore, the second nut 353b, which constitutes the second motion converters 353b and 354b, can be arranged at a position symmetrical to the position of the first nut 353a of the first motion converters 353a and 354a, and formed into a shape symmetrical to its shape.

[0328] Furthermore, the detailed configuration of the second link 354b, which constitutes the second motion converters 353b and 354b and includes the second drive link 354b1 and the second driven link 354b2, can be arranged at a position symmetrical to the position of the first link 354a of the first motion converters 353a and 354a, and formed into a shape symmetrical to its shape.

[0329] Since the second motion converters 353b and 354b are arranged in positions symmetrical to the positions of the first motion converters 353a and 354a, and are formed in a shape symmetrical to their shapes, the following description of redundant content regarding the second motion converters 353b and 354b will be omitted.

[0330] In one example, as described above, in this disclosure, the pop-out handle 31 is driven by a single drive motor 351 and by first motion converters 353a and 354a and second motion converters 353b and 354b, which are arranged in symmetrical positions and formed in symmetrical shapes.

[0331] Therefore, due to the machining and assembly tolerances of the first motion converters 353a and 354a, the second motion converters 353b and 354b, and the pop-up handle 31, the stroke Ls of the pop-up handle 31 from the retracted position Pa to the extended position Pd may be different at the second handle body 3112 and the third handle body 3113.

[0332] In other words, there is a high probability that a positional deviation in the front-rear direction (FR direction) will occur between the second handle body 3112 and the third handle body 3113.

[0333] When the positional deviation between the second handle body 3112 and the third handle body 3113 in the front-rear direction (FR direction) reaches a predetermined level or higher, the load on the drive motor 351 may increase rapidly.

[0334] Furthermore, the load on the first motion converters 353a and 354a and the second motion converters 353b and 354b, which convert the driving force and transmit the converted driving force to the second handle body 3112 and the third handle body 3113 respectively, may increase rapidly, thus there is a possibility that the first motion converters 353a and 354a and the second motion converters 353b and 354b may be damaged.

[0335] In addition, it may cause damage to the second handle body 3112 and the third handle body 3113 that constitute the pop-out handle 31.

[0336] As a device for minimizing the positional deviation between the second handle body 3112 and the third handle body 3113 that may occur during the reciprocating movement of the pop-up handle 31, the handle driver 35 of the pop-up handle 31 of the dishwasher 1 according to the present disclosure may include positional deviation adjusters 356a and 356b.

[0337] More in detail, such as Figure 7As illustrated, position deviation adjusters 356a and 356b may include a first deviation adjuster 356a that adjusts the position of the second handle body 3112 in the front-rear direction (FR direction) and a second deviation adjuster 356b that adjusts the position of the third handle body 3113 in the front-rear direction (FR direction).

[0338] When a deviation occurs between the position of the second handle body 3112 in the front-rear direction (FR direction) and the position of the third handle body 3113 in the front-rear direction, the first deviation adjuster 356a and the second deviation adjuster 356b can be configured to apply force respectively to push the second handle body 3112 and the third handle body 3113 forward or backward.

[0339] The first deviation adjuster 356a and the second deviation adjuster 356b can be arranged in positions symmetrical to each other relative to the vertical surface of the pop-out handle 31 which is equally divided along the horizontal direction, so as to apply force to push the second handle body 3112 and the third handle body 3113 in the direction that minimizes the positional deviation.

[0340] Furthermore, for the same reason, the first deviation adjuster 356a and the second deviation adjuster 356b may have shapes that are symmetrical to each other relative to the vertical surface of the pop-out handle 31 which is equally divided along the horizontal direction.

[0341] Please refer to later Figures 15 to 17 The description includes detailed configurations of the deviation adjusters 356a and 356b, including the positions of the first deviation adjuster 356a and the second deviation adjuster 356b.

[0342] In one example, the dishwasher 1 according to an embodiment of the present disclosure may include a blind module 37 that covers the opening 30e through which the pop-up handle 31 passes when the pop-up handle 31 moves from the retracted position Pa to the extended position Pd.

[0343] As described above, when the eject handle 31 moves to the extended position Pd, the opening 30e of the front panel 30a, which extends through the front panel 30a in the front-rear direction (FR direction) to allow the eject handle 31 to pass through, is at least partially opened, except for the portion occupied by the second handle body 3112 and the third handle body 3113.

[0344] The blind module 37 is used to cover the opening 30e and the handle inlet 30d2, so that foreign objects are not introduced or the interior of the door 30 is not observed through the opening 30e, which is at least partially open forward, and the handle inlet 30d2 of the handle frame 30d, which will be described later.

[0345] First, such as Figure 8 and Figure 9As illustrated, the blind module 37 may, illustratively, include a blind panel 371 that is movable in the forward-backward (FR) direction in association with the reciprocating motion of the pop-up handle 31.

[0346] More specifically, the blind panel 371 may include a panel body 3711 having a plate-like shape, which covers the opening 30e and the handle inlet 30d2.

[0347] The panel body 3711 may have a rectangular shape corresponding to the shape of the opening 30e and the handle inlet 30d2.

[0348] The width of the panel body 3711 in the left-right direction can be set to be equal to or slightly less than the width of the space between the second handle body 3112 and the third handle body 3113 in the left-right direction, so as to cover the opening 30e and handle inlet 30d2 that are partially opened after the pop-up handle 31 moves to the extended position Pd.

[0349] When the opening 30e and the handle inlet 30d2 are covered by the panel body 3711, the front surface 3711a of the panel body 37111 is exposed to the outside through the opening 30e and the handle inlet 30d2.

[0350] In order to minimize the difference from the front panel 30a, the front surface 3711a of the panel body 3711 can be surface treated to have the same texture and color as the front surface of the front panel 30a.

[0351] Furthermore, when the opening 30e and the handle inlet 30d2 are covered by the panel body 3711, the front surface 3711a of the panel body 3711 can form a continuous surface with the front surface of the front panel 30a, or it can be in a state that protrudes slightly from the front panel 30a.

[0352] Therefore, since the front surface 3711a forms the same surface as the front surface of the front panel 30a and is arranged to protrude slightly from the front panel 30a, foreign objects such as dust can be prevented from accumulating in the opening 30e and the handle inlet 30d2.

[0353] The blind panel 371 may also include flanges 3712 formed on the upper end surface 3711b and the lower end surface 3711c of the panel body 3711.

[0354] When the covering position is reached, the front surface 3711a of the panel body 3711 needs to form a continuous surface with the front surface of the front panel 30a, or stop in a state that protrudes slightly from the front panel 30a.

[0355] Flange 3712 serves as a stop to prevent panel body 3711 from moving further forward from its foremost position after reaching the foremost position.

[0356] Considering the shape of the panel body 3711, the flange 3712 can extend linearly along the rear edge of the upper surface 3711b of the panel body 3711.

[0357] In addition, the flange 3712 can extend linearly along the rear edge of the lower end surface 3711c of the panel body 3711.

[0358] Furthermore, the height at which the flange 3712 protrudes from the upper surface 3711b of the panel body 3711 and the height at which the flange 3712 protrudes from the lower surface 3711c of the panel body 3711 can be maintained evenly from the left end to the right end of the panel body 3711.

[0359] As will be described later, when the panel body 3711 moves to the foremost position, the flange 3712 may come into contact with and collide with the rear edge of the inlet rib 30d3 of the handle frame 30d, so the panel body 3711 may stop at the foremost position.

[0360] In one example, as illustrated in the embodiment, a plurality of slots 3712a may be defined in the flange 3712.

[0361] Multiple slots 3712a can extend from the upper edge to the lower edge of the flange 3712 along the vertical direction (UD direction).

[0362] Furthermore, the widths of the multiple slots 3712a in the left-right direction can be set to be substantially equal to each other.

[0363] Furthermore, a plurality of reinforcing ribs 30d4 formed inside the handle frame 30d, which will be described later, can be inserted into a plurality of slots 3712a.

[0364] As will be described later, the thickness of each reinforcing rib 30d4 is maintained substantially uniformly along the front-to-back direction (FR direction).

[0365] Furthermore, the width of each of the multiple slots 3712a in the left-right direction can be equal to or slightly greater than the thickness of the reinforcing rib 30d4 of the handle frame 30d.

[0366] As described above, since the blind panel 371 is arranged such that the reinforcing rib 30d4 of the handle frame 30d is inserted into the corresponding slot 3712a, the slot 3712a of the flange 3712 and the reinforcing rib 30d4 of the handle frame 30d can be used as guiding devices for guiding the reciprocating motion of the blind panel 371.

[0367] In one example, the blind panel 371 can be connected to the first bracket 372 and the second bracket 373, which will be described later, such that the spacing between them in the front-rear direction (FR direction) is variable.

[0368] At least one first protrusion 3711d protruding toward the first bracket 372 and the second bracket 373 may be arranged on the rear surface of the panel body 3711 so as to be connected to the first bracket 372 and the second bracket 373 in a state that defines such variable spacing.

[0369] In the illustrated embodiment, a configuration is illustrated in which the first support 372 is connected via a total of four first protrusions 3711d and the second support 373 is connected via a total of four first protrusions 3711d.

[0370] However, this is only one example. The number of first protrusions 3711d can be adjusted according to the width of the blind panel 371 in the left-right direction or in the vertical direction.

[0371] The first protrusion 3711d can be connected in a telescopic manner, so that the spacing in the front-rear direction (FR direction) is variable.

[0372] For telescopic connection, the first protrusion 3711d may be a solid rib, and the second protrusion 3721d to which the first protrusion 3711d is connected and inserted may be a hollow rib.

[0373] As will be described later, the second protrusion 3721d can protrude from the front surface 3721a of the first bracket 372 and the front surface 3731a of the second bracket 373 toward the panel body 3711.

[0374] In addition, the blind module 37 may include supports 372 and 373 that support the blind panel 371 so that it can move relative to it.

[0375] In this regard, for the shape of the blind panel 371 changing from the left-right direction (Le-Ri direction) to the longitudinal direction and to prevent interference with the drive motor 351 arranged at the rear of the blind panel 371, illustratively, brackets 372 and 373 can be divided into a first bracket 372 and a second bracket 373.

[0376] The first bracket 372 is used to support the left side portion of the blind panel 371 so that it can be moved relative to the blind panel 371 and prevent the blind panel 371 from shifting backward.

[0377] At least one second protrusion 3721d protruding toward the left portion of the blind panel 371 may be arranged on the front surface 3721a of the support body 3721 of the first support 372 in order to support the blind panel 371 in a relatively movable manner, that is, to allow the spacing between the blind panel 371 and the first support 372 in the front-rear direction (FR direction) to vary.

[0378] As in this embodiment, when a total of four first protrusions 3711d are arranged on the rear surface of the blind panel 371, a total of four second protrusions 3721d can be arranged correspondingly on the front surface 3721a of the support body 3721 of the first support 372.

[0379] As described above, each of the second protrusions 3721d of the first support 372 can be a hollow rib so as to be telescopically connected to the first protrusion 3711d of the blind panel 371.

[0380] The hollow portion confined inside the second protrusion 3721d of the first support 372 can be continuously confined from the front end of the second protrusion 3721d to the rear surface of the support body 3721 of the first support 372.

[0381] The first bracket 372 can be fastened to the handle frame 30d, which will be described later.

[0382] To secure the handle frame 30d, the first bracket 372 may include a plurality of fastening bosses 3721c, through which screw holes are defined in the front-rear direction (FR direction).

[0383] By way of example, a plurality of fastening bosses 3721c of the first bracket 372 may be configured as a pair near the upper surface of the bracket body 3721 of the first bracket 372, and may be configured as a pair near the lower surface of the bracket body 3721 of the first bracket 372.

[0384] Corresponding to the multiple fastening bosses 3721c of the first bracket 372, two pairs of second screw bosses 30d6, with handle inlet 30d2 arranged between the two, can be integrally formed inside the handle frame 30d.

[0385] In one example, as described above, the first bracket 372 can also be used to rotatably support the first lead screw 352a.

[0386] Therefore, the bushing 3722 can be integrally formed with the left end surface 3721b of the support body 3721 of the first support 372.

[0387] Bushing 3722 may include a circular hole defined therethrough in a left-right direction.

[0388] When inserted into the round hole of the bushing 3722 of the first bracket 372, the left end of the first lead screw 352a can be rotatably supported by the bushing 3722.

[0389] In one example, similar to the first bracket 372, the second bracket 373 is used to support the right side portion of the blind panel 371 so as to allow relative movement and prevent the blind panel 371 from shifting backward.

[0390] Similar to the first bracket 372, at least one second protrusion 3731d protruding toward the left side of the blind panel 371 can be arranged on the front surface 3731a of the bracket body 3731 of the second bracket 373 to support the right side of the blind panel 371 in a relatively movable manner, that is, to allow the spacing between the blind panel 371 and the second bracket 373 to vary in the front-rear direction (FR direction).

[0391] As in this embodiment, when a total of four first protrusions 3711d are arranged on the rear surface of the blind panel 371, a total of four second protrusions 3731d can be arranged correspondingly on the front surface 3731a of the support body 3731 of the second bracket 373.

[0392] As described above, each of the second protrusions 3731d of the second support 373 can be a hollow rib so as to be telescopically connected to the first protrusion 3711d of the blind panel 371.

[0393] The hollow portion that is confined inside the second protrusion 3731d of the second support 373 can be continuously confined from the front end of the second protrusion 3731d of the second support 373 to the rear surface of the support body 3731 of the second support 373.

[0394] Like the first bracket 372, the second bracket 373 can be fastened to the handle frame 30d, which will be described later.

[0395] To secure it to the handle frame 30d, the second bracket 373 may include a plurality of fastening bosses 3731c, through which screw holes are defined in the front-to-back direction.

[0396] By way of example, a plurality of fastening bosses 3731c of the second bracket 373 may be configured as a pair near the upper surface of the bracket body 3731 of the second bracket 373, and may be configured as a pair near the lower surface of the bracket body 3731 of the second bracket 373.

[0397] Corresponding to the multiple fastening bosses 3731c of the second bracket 373, two pairs of second screw bosses 30d6, with the handle inlet 30d2 located between the two, can be integrally formed inside the handle frame 30d.

[0398] In addition, the second bracket 373 can also be used to rotatably support the second lead screw 352b.

[0399] Therefore, bushing 3732 can be integrally formed with the right end surface 3731b of the support body 3731 of the second support 373.

[0400] The bushing 3732 of the second bracket 373 may include a circular hole defined therethrough in the left-right direction.

[0401] When inserted into the round hole of the bushing 3722 of the second bracket 373, the right end of the second lead screw 352b can be rotatably supported by the bushing 3722.

[0402] In one example, the blind module 37 may also include a plurality of compression springs 374 arranged between the first bracket 372 and the blind panel 371, and arranged between the second bracket 373 and the blind panel 371.

[0403] Multiple compression springs 374 are used to push the blind panel 371 forward, causing the blind panel 371 to move in association with the reciprocating movement of the pop-up handle 31.

[0404] Therefore, a restoring force can be provided by multiple compression springs 374 to form a continuous surface between the front end surface 3711a of the blind panel 371 and the front panel 30a. In this respect, since the rear side of the front panel 30a is compressed by multiple compression springs 374, the blind panel 371 can be easily pressed backward when the user presses it. Therefore, even when the user's finger or a foreign object is caught between the first handle body 3111 and the blind panel 371, the blind panel 371 can be easily pressed backward, thus ensuring space for the finger or object to escape, thereby improving safety.

[0405] When the blind panel 371 is supported so that it can move relative to the first bracket 372 and the second bracket 373, at least one compression spring 374 can be arranged between the first bracket 372 and the left side portion of the blind panel 371 and between the second bracket 372 and the right side portion of the blind panel 371.

[0406] In the illustrated embodiment, an exemplary configuration is shown in which the compression spring 374 is equipped as a helical spring, which is arranged in a compressed state between the first bracket 372 and the blind panel 371 and between the second bracket 373 and the blind panel 371.

[0407] This disclosure is not limited thereto, but will be described based on an embodiment in which the helical spring is configured as a compression spring 374.

[0408] A compression spring 374 disposed between the first bracket 372 and the left side portion of the blind panel 371 can be arranged such that the first protrusion 3711d of the blind panel 371 and the second protrusion 3721d of the first bracket 372 pass through the space defined therein.

[0409] In this respect, the front end of the compression spring 374 contacts the rear surface of the left side portion of the blind panel 371.

[0410] In addition, the rear end of the compression spring 374 contacts the front surface 3721a of the first bracket 372.

[0411] Thus, since the compression spring 374 is in contact with the rear surface of the left side portion of the blind panel 371 and the front surface 3721a of the first bracket 372 when it is in a compressed state, a state in which the restoring force of the compression spring 374 always pushes the left side portion of the blind panel 371 forward can be formed.

[0412] Furthermore, the compression spring 374 arranged between the second bracket 373 and the right side portion of the blind panel 371 can be arranged such that the first protrusion 3711d of the blind panel 371 and the second protrusion 3731d of the second bracket 373 pass through the space defined therein.

[0413] In this respect, the front end of the compression spring 374 contacts the rear surface of the right side portion of the blind panel 371.

[0414] In addition, the rear end of the compression spring 374 contacts the front surface 3731a of the second bracket 373.

[0415] Since the compression spring 374 is in contact with the rear surface of the right side portion of the blind panel 371 and the front surface 3731a of the second bracket 373 when it is in a compressed state, a state in which the restoring force of the compression spring 374 always pushes the left side portion of the blind panel 371 forward can be formed.

[0416] In the illustrated embodiment, a configuration is shown in which a compression spring 374 is arranged between the first bracket 372 and the left side portion of the blind panel 371, and a compression spring 374 is arranged between the second bracket 373 and the right side portion of the blind panel 371.

[0417] The number of compression springs 374 provided can be increased depending on the size and weight of the blind panel 371.

[0418] However, the number of compression springs 374 arranged between the first bracket 372 and the left side portion of the blind panel 371 and the number of compression springs 374 arranged between the second bracket 373 and the right side portion of the blind panel 371 can be set to be equal to each other, so that equal restoring forces can be applied to both sides of the blind panel 371.

[0419] Furthermore, for the same reason, the spring constant of the compression spring 374 arranged between the first bracket 372 and the left portion of the blind panel 371 and the spring constant of the compression spring 374 arranged between the second bracket 373 and the right portion of the blind panel 371 can be set to be equal to each other.

[0420] Please refer to later Figures 12 to 14h The process of the blind panel 371 moving in relation to the movement of the pop-up handle 31 is described in detail.

[0421] In one example, a dishwasher 1 according to an embodiment of the present disclosure may include a handle frame 30d in which a handle driver 35 and a pop-out handle 31 are received.

[0422] More specifically, the handle frame 30d may include a frame body 30d1 in which the pop-out handle 31 and the handle driver 35 are housed.

[0423] like Figure 6 and Figure 7 As shown, the frame body 30d1 may have a hollow box shape to fully accommodate and support the pop-out handle 31 and the handle driver 35.

[0424] In this respect, the rear surface of the frame body 30d1 can be in an open state, allowing the pop-out handle 31 and handle driver 35 to be assembled from the rear.

[0425] In this regard, to prevent the introduction of water leakage, an upper wall 30d12 constituting the upper surface of the frame body 30d1, a lower wall 30d13 constituting the lower surface, a left wall 30d14 constituting the left side surface, and a right wall 30d15 constituting the right side surface can be formed in a normally blocked state.

[0426] In one example, a handle inlet 30d2 having a cross-sectional area and shape corresponding to the appearance of the pop-out handle 31 can be defined by the front wall 30d11 of the frame body 30d1, allowing the pop-out handle 31 to enter and exit. Therefore, the front wall 30d11 of the frame body 30d1 can be partially opened.

[0427] The handle inlet 30d2 can be directly defined at the rear of the opening 30e in the front panel 30a, and can have a shape substantially the same as the opening 30e in the front panel 30a. However, as will be described later, the cross-sectional area of ​​the handle inlet 30d2 can be slightly larger than the cross-sectional area of ​​the opening 30e, such that the opening flange 30e1 formed in the opening 30e in the front panel 30a can pass through the handle inlet 30d2.

[0428] To improve space utilization, the control panel retainer 321, which houses the aforementioned control panel 32, can be connected to the upper wall 30d12 of the frame body 30d1 in a surface contact state.

[0429] Furthermore, for the same reason, the left wall 30d14 of the frame body 30d1 can be formed as close as possible to the left side surface of the front panel 30a of the door 30, while the right wall 30d15 of the frame body 30p1 can be formed as close as possible to the right side surface of the front panel 30a of the door 30.

[0430] Furthermore, the front wall 30d11 of the frame body 30d1 can be arranged in a state of close contact with the rear surface of the front panel 30a of the door 30 in a surface contact state.

[0431] Therefore, the overall rigidity of the front panel 30a can be enhanced.

[0432] In particular, due to the defined opening 30e, the rigidity of the front panel 30a at locations where its rigidity may be significantly reduced can be enhanced by the frame body 30d1.

[0433] In one example, a baseboard frame 30f that houses and supports the driver control board 35 for controlling the handle driver 35 can be arranged below the handle frame 30d.

[0434] As described above, the control panel holder 321, which houses the control panel 32 for controlling the operation of the dishwasher 1 and the control panel base plate (not shown), can be connected to the upper wall 30d12 of the frame body 30d1.

[0435] In other words, as in the illustrated embodiment, the driver control board 357 for controlling the handle driver 35 can be arranged separately in the board frame 30f from the control panel 32 and the control panel board (not shown).

[0436] However, unlike the illustrated embodiment, the control board can be integrated into a single control board capable of controlling the operation of the dishwasher 1 and the operation of the eject handle 31. Therefore, the internal structure of the door 30 can be simplified.

[0437] Whether the control panel board and the drive control board 357 are provided separately or integrated as described above, all of them can be electrically connected to the main controller (not shown) arranged in the main body of the dishwasher 1. Therefore, the operation of the various detailed components constituting the dishwasher 1, including the pop-out handle 31, can be controlled by the main controller.

[0438] The substrate frame 30f can be formed separately and connected to the handle frame 30d, or it can be formed integrally with the handle frame 30d.

[0439] Figure 6 An exemplary illustration shows a baseboard frame 30f integrally connected to and formed integrally with a handle frame 30d.

[0440] When the base plate frame 30f and the handle frame 30d are integrally formed, the separate fastening device for fixing the base plate frame 30f to the front panel 30a of the door 30 can be omitted.

[0441] The handle frame 30d and the base plate frame 30f can be directly fastened to the front panel 30a of the door 30, or indirectly fastened to the front panel 30a of the door 30.

[0442] The mounting bracket 30g can be arranged as a device for indirectly fastening the handle frame 30d to the front panel 30a of the door 30.

[0443] like Figure 6 and Figure 7 As illustrated, the fixing bracket 30g can extend in a shape that at least partially surrounds the rear edge of the frame body 30d1 of the handle frame 30d.

[0444] As illustrated, the fixing bracket 30g may include multiple fastening holes through which fastening devices such as bolts can pass.

[0445] Some of the multiple fastening holes are used to fasten the fixing bracket 30g to the front panel 30a of the door 30, and the remaining fastening holes are used to fasten the fixing bracket 30g to the frame body 30d1 of the handle frame 30d.

[0446] Examplely, the screw boss for fastening the bolt that has passed through the fastening hole of the fixing bracket 30g can be integrally formed with the left wall 30d14, right wall 30d15 and lower wall 30d13 of the frame body 30d1.

[0447] As described above, the handle frame 30d and the base plate frame 30f can be indirectly fastened to the front panel 30a of the door 30 by means of the fixing bracket 30g.

[0448] A device for directly fastening a handle frame 30d to the front panel 30a of a door 30 can be arranged on the entrance rib 30d3 of the frame body 30d1.

[0449] like Figure 11 As illustrated, a rearwardly extending opening flange 30e1 can be arranged in the opening 30e of the front panel 30a of the door 30.

[0450] The opening flange 30e1 can be formed by bending the front panel 30a portion backward and plastically deforming it.

[0451] The opening flange 30e1 can be integrally formed with the lower and upper edges of the opening 30e.

[0452] The opening flange 30e1 formed at the lower edge of the opening 30e can extend linearly along the lower edge of the opening 30e.

[0453] Furthermore, as the opening flange extends along the lower edge of the opening 30e, the width of the opening flange 30e1 formed at the lower edge of the opening 30e in the front-back direction can remain substantially uniform.

[0454] The opening flange 30e1 formed at the upper edge of the opening 30e can extend linearly along the upper edge of the opening 30e.

[0455] Furthermore, as the opening flange 30e1 extends along the upper edge of the opening 30e, the width of the opening flange 30e1 formed at the upper edge of the opening 30e in the front-back direction can remain substantially uniform.

[0456] like Figure 10 As illustrated, the opening flange 30e1 can pass through the handle inlet 30d2 of the frame body 30d1 of the handle frame 30d and extend into the interior of the frame body 30d1.

[0457] Similar to the opening flange 30e1 of the front panel 30a of the door 30, the handle inlet 30d2 of the handle frame 30d can be integrally formed with the inlet rib 30d3 extending inward to the frame body 30d1.

[0458] The inlet rib 30d3 can be integrally formed with the lower edge of the handle inlet 30d2 and the upper edge of the handle inlet 30d2.

[0459] The inlet rib 30d3 formed at the lower edge of the handle inlet 30d2 can extend linearly along the lower edge of the handle inlet 30d2.

[0460] Furthermore, as the inlet rib 30d3 extends along the lower edge of the handle inlet 30d2, the width of the inlet rib 30d3 formed at the lower edge of the handle inlet 30d2 in the front-back direction can remain generally uniform.

[0461] The inlet rib 30d3 formed at the upper edge of the handle inlet 30d2 can extend linearly along the upper edge of the handle inlet 30d2.

[0462] Furthermore, as the inlet rib 30d3 extends along the upper edge of the handle inlet 30d2, the width of the inlet rib 30d3 formed at the upper edge of the handle inlet 30d2 in the front-back direction can remain generally uniform.

[0463] The width of the inlet rib 30d3 formed at the handle inlet 30d2 in the front-back direction can be set to be equal to or greater than the width of the opening flange 30e1 formed at the opening 30e of the door 30 in the front-back direction.

[0464] In this respect, as illustrated in the figure, a plurality of hook holes 30e2 can be defined to extend vertically through an opening flange 30e1 formed at an opening 30e in the door 30.

[0465] Multiple hooks 30d31 that are detachably connected to each hook hole 30e2 can be integrally formed with the inlet rib 30d3 at positions corresponding to the positions of each hook hole 30e2.

[0466] Each hook 30d31 can be integrally formed with the entrance rib 30d3 by partially cutting the entrance rib 30d3.

[0467] Therefore, when each hook 30d31 is inserted into and connected to its corresponding hook hole 30e2, the multiple hooks 30d31 and the multiple hook holes 30e2 serve as a means for directly fastening the handle frame 30d to the front panel 30a of the door 30.

[0468] Furthermore, the opening flange 30e1 of the door 30 and the entrance rib 30d3 of the handle frame 30d are configured to be connected to each other in a surface contact state.

[0469] Due to this surface contact connection, the opening flange 30e1 of the door 30 and the entrance rib 30d3 of the handle frame 30d can reinforce each other in terms of rigidity.

[0470] In one example, such as Figure 10 As shown, multiple reinforcing ribs 30d4 can be integrally formed with the interior of the frame body 30d1 of the handle frame 30d.

[0471] As described above, the frame body 30d1 of the handle frame 30d is formed as a hollow box shape.

[0472] Furthermore, the rear surface of the frame body 30d1 is completely open, and the handle inlet 30d2, which corresponds to the appearance of the pop-out handle 31, is defined by passing through the front wall 30d11 of the frame body 30d1.

[0473] Therefore, multiple reinforcing ribs 30d4 can be integrally formed to prevent the rigidity of the frame body 30d1 from deteriorating due to the complete opening of the rear surface and the partial opening of the front wall 30d11.

[0474] Considering the complete openness of the rear surface and the partial openness of the front wall 30d11, multiple reinforcing ribs 30d4 can be arranged in a vertically separated manner based on the handle inlet 30d2.

[0475] The reinforcing rib 30d4, which is located above the handle inlet 30d2, can be integrally connected to the front wall 30d11 and the upper wall 30d12 of the frame body 30d1.

[0476] The reinforcing rib 30d4, located below the handle inlet 30d2, can be integrally connected to the front wall 30d11 and the lower wall 30d13 of the frame body 30d1.

[0477] In addition, each reinforcing rib 30d4 can extend linearly in the front-back direction.

[0478] In this respect, the lengths of each reinforcing rib 30d4 extending from the front wall 30d11 of the frame body 30d1 can vary from one another depending on their position.

[0479] However, as the reinforcing ribs 30d4 extend along the front-rear direction (FR direction), the thickness of each reinforcing rib 30d4 can remain generally uniform.

[0480] As described above, each of the reinforcing ribs 30d4 is configured to be inserted into a slot 3712a in the flange 3712 defined in the blind panel 371, such that the slot 3712a of the flange 3712a of the blind panel 371 and the reinforcing ribs 30d4 of the handle frame 30d can be used as guides for guiding the reciprocating motion of the blind panel 371.

[0481] In one example, as illustrated, the first screw boss 30d5 and the second screw boss 30d6 can be arranged between corresponding pairs of adjacent reinforcing ribs 30d4.

[0482] As described above, the first screw boss 30d5 serves the purpose of using bolts to secure the motor bracket 3511a.

[0483] Furthermore, as described above, the second screw boss 30d6 serves the purpose of using bolts to secure the first bracket 372 and the second bracket 373 of the blind module 37.

[0484] In this respect, additional ribs extending in the left-right direction can be arranged between the first screw boss 30d5 and its adjacent reinforcing rib 30d4, and between the second screw boss 30p6 and its adjacent reinforcing rib 30d4, so as to integrally connect them. Therefore, the connection strength and rigidity between the first screw boss 30d5, the second screw boss 30p6 and the reinforcing rib 30d4 can be additionally ensured.

[0485] In one example, the handle frame 30d can also be used to guide the back-and-forth reciprocating motion of the pop-up handle 31.

[0486] In other words, as described above, the pop-out handle 31 can be configured to move horizontally in the forward direction Dfw or the backward direction Drw by the forward or reverse driving force of the handle driver 35.

[0487] A device for achieving this horizontal movement can be arranged on the pop-out handle 31 and the handle frame 30d in which the pop-out handle 31 is housed.

[0488] As a device for achieving horizontal movement, the pop-out handle 31 may include a pair of guide blocks 3114.

[0489] As described above, one of the pair of guide blocks 3114 can be fixed to the left side surface of the second handle body 3112.

[0490] In addition, the other of the pair of guide blocks 3114 can be fixed to the right side surface of the third handle body 3113.

[0491] In this respect, when the guide block 3114 extends along the front-rear direction (FR direction), the thickness of a pair of guide blocks 3114 in the left-right direction (Le-Ri direction) can remain uniform.

[0492] Furthermore, when the guide block 3114 extends along the front-rear direction (FR direction), the height of a pair of guide blocks 3114 in the vertical direction (UD direction) can remain uniform.

[0493] In one example, the handle frame 30d may include guide brackets 30h1 and 30h2 as a means of achieving horizontal movement.

[0494] Guide brackets 30h1 and 30h2 are used to accommodate the second handle body 3112 and the third handle body 3113 of the pop-out handle 31, and to guide the front-back horizontal movement of the second handle body 3112 and the third handle body 3113.

[0495] By way of example, guide brackets 30h1 and 30h2 may include a first guide bracket 30h1 in which a second handle body 3112 is received and a second guide bracket 30h2 in which a third handle body 3113 is received.

[0496] The first guide bracket 30h1 and the second guide bracket 30h2 can be integrally formed with the frame body 30d1 of the handle frame 30d.

[0497] Furthermore, the first guide bracket 30h1 and the second guide bracket 30h2 can be formed separately from the frame body 30d1 and fastened to the frame body 30d1.

[0498] In the illustrated embodiment, a configuration is shown in which the first guide bracket 30h1 and the second guide bracket 30h2 are separately formed and fastened to the frame body 30d1. This disclosure is not limited thereto, but will be described based on the illustrated embodiment.

[0499] First, such as Figure 11 As shown, the first guide bracket 30h1 can be formed as a hollow box shape, so that the second handle body 3112 can be movably accommodated therein.

[0500] In this respect, the front and rear surfaces of the first guide bracket 30h1 can be fully opened to ensure the horizontal movement of the second handle body 3112 in the front-rear direction (FR direction).

[0501] Furthermore, in order to prevent interference with the first drive link 354a1 and the first driven link 354a2 that constitute the handle driver 35, the right side surface of the first guide bracket 30h1 can be completely opened.

[0502] In this respect, a block guide groove 30h12 that protrudes to the left (Le direction) can be formed on the left side surface of the first guide bracket 30h1.

[0503] The guide block 3114 attached to the second handle body 3112 can be inserted into the block guide slot 30h12.

[0504] The block guide groove 30h12 may have a cross-sectional shape corresponding to the appearance of the guide block 3114 attached to the second handle body 3112.

[0505] In addition, the block guide groove 30h12 can extend linearly along the front-rear direction (FR direction).

[0506] Therefore, when the second handle body 3112 moves with the guide block 3114 inserted into the block guide groove 30h12, it can guide the second handle body 3112 to move horizontally in the front-rear direction (FR direction).

[0507] Furthermore, as described above, the pin guide slot 30h11, which extends linearly along the front-rear direction (FR direction), can be vertically defined by passing through the upper and lower surfaces of the first guide block 3114.

[0508] The upper end of the second movable pin Pm2 is inserted into the pin guide groove 30h11 defined in the upper surface of the first guide block 3114 and connected to the pin guide groove.

[0509] Furthermore, the upper end of the second movable pin Pm2 is inserted into the pin guide groove 30h11 defined in the lower surface of the first guide block 3114 and connected to the pin guide groove.

[0510] As described above, the other end of the first drive linkage 354a1 is connected to the second handle body 3112 in a rotatable manner via the second movable pin Pm2.

[0511] Since the movement is guided in the state where the second movable pin Pm2 is inserted into the pin guide slot 30h11, the other end of the second handle body 3112 and the first drive link 354a1 can be guided in this direction of movement, so that they move horizontally along the pin guide slot 30h11 in the front-rear direction (FR direction).

[0512] In one example, the pin hole 30h1 into which the retaining pin Pf for connecting the other end of the first driven link 354a2 to the first guide bracket 30h1 in a relatively rotatable manner is inserted and connected can be defined as extending vertically (UD direction) through the upper and lower surfaces of the first guide bracket 30h1 respectively.

[0513] In one example, at least one sensor hole 30h14 may be defined by passing through the lower surface of the first guide bracket 30h1 in the vertical direction (UD direction).

[0514] like Figure 11 As illustrated, the dishwasher 1 according to an embodiment of the present disclosure may include a handle position sensor module S_h as a means for sensing the position of the pop-out handle 31.

[0515] In this embodiment, as an example, a configuration is illustrated in which the handle position sensor module S_h includes a first switch S_h1 and a second switch S_h2 that output ON-OFF signals.

[0516] When the handle position sensor module S_h is composed of a first switch S_h1 and a second switch S_h2 as described above, the first switch S_h1 and the second switch S_h2 can be arranged in a row along the front-back direction (FR direction).

[0517] Example: The first switch S_h1 can be arranged in front, while the second switch S_h2 can be arranged in the rear.

[0518] In this respect, the lever of the first switch S_h1 and the lever of the second switch S_h2 can pass through the sensor hole 30h14 and extend inward, respectively.

[0519] Therefore, as illustrated in the figure, when the second handle body 3112 is in the retracted position Pa, the levers of the first switch S_h1 and the second switch S_h2 are pressed by the lower surface of the second handle body 3112.

[0520] Therefore, when the second handle body 3112 is in the retracted position Pa, both the first switch S_h1 and the second switch S_h2 output an ON signal.

[0521] Furthermore, when the second handle body 3112 begins to move from the retracted position Pa toward the extended position Pd, the output signal of the second switch S_h2 can be converted into an OFF signal.

[0522] Furthermore, when the second handle body 3112 moves to the extended position Pd, the output signal of the first switch S_h1 can be converted into an OFF signal.

[0523] By detecting the conversion of the output signals of the first switch S_h1 and the second switch S_h2 from ON to OFF signals, the current position of the second handle body 3112 and whether the second handle body 3112 is moving can be detected effectively and easily.

[0524] In one example, the first switch S_h1 and the second switch S_h2 can be arranged between the lower wall 30d13 of the frame body 30d1 and the lower surface of the first guide bracket 30h1, wherein they are jointly fastened to and supported by the sensor holder S_h3.

[0525] In one example, the second guide bracket 30h2 may be positioned symmetrically to the position of the first guide bracket 30h1 relative to a vertical surface that is equally divided along the horizontal direction by the pop-out handle 31 so as to movably accommodate the third handle body 3113 therein.

[0526] Furthermore, for the same reason, the second guide bracket 30h2 may have a shape that is symmetrical to the first guide bracket 30h1 relative to the vertical surface that divides the pop-out handle 31 equally along the horizontal direction.

[0527] Since the second guide bracket 30h2 has a shape and position symmetrical to the first guide bracket 30h1, the redundant description of the second guide bracket 30h2 will be omitted below.

[0528] [The movement of the pop-up controller and the actions of the blind module based on the controller driver]

[0529] In the following text, refer to Figures 12 to 14dThe process in which the pop-up handle 31 moves forward from the retracted position Pa to the extended position Pd based on the operation of the handle driver 35, and the process in which the opening 30e and the handle inlet 30d2 are covered by a blind module associated with the movement of the pop-up handle 31, will be described.

[0530] first, Figure 12 The diagram shows the state in which the pop-up handle 31 is stopped at the retracted position Pa.

[0531] When from Figure 12 When the state illustrated above supplies power to the drive motor 351, the forward movement of the pop-out handle 31 from the retracted position Pa toward the extended position Pd can begin.

[0532] Reference Figure 10 When power is supplied to the drive motor 351 while the pop-out handle 31 is in the retracted position Pa and stops, the operation of the drive motor 351 begins and the drive motor 351 generates a positive rotational driving force.

[0533] Therefore, the first output shaft 3512a and the second output shaft 3512b of the drive motor 351 can be started to rotate in the forward direction.

[0534] In this respect, when the first output shaft 3512a and the second output shaft 3512b begin to rotate in the forward direction, the first nut 353a screwed to the first output shaft 3512a begins to move linearly to the left, while the second nut 353b screwed to the second output shaft 3512b begins to move linearly to the right.

[0535] As the first nut 353a begins to move linearly to the left, one end of the first drive link 354a1, which is rotatably connected to the first nut 353a via the first movable pin Pm1, moves to the left.

[0536] Furthermore, as the second nut 353b begins to move linearly to the right, one end of the second drive link 354b, which is rotatably connected to the second nut 353b via the first movable pin Pm1, moves to the right.

[0537] In this respect, the first drive link 354a1 is connected to one end of the first driven link 354a2 at the middle position via the third movable pin Pm3.

[0538] Furthermore, the second drive link 354b1 is connected to one end of the second driven link 354b2 at the middle position via the third movable pin Pm3.

[0539] Therefore, based on Figure 12 As illustrated, the first drive link 354a1 rotates clockwise completely around the third movable pin Pm3.

[0540] Furthermore, the second drive link 354b1 rotates completely around the third movable pin Pm3 in a counterclockwise direction.

[0541] When the first drive link 354a1 rotates clockwise around the third movable pin Pm3, the other end of the first drive link 354a1 rotates to point forward.

[0542] Furthermore, when the second drive link 354b1 rotates counterclockwise around the third movable pin Pm3, the other end of the second drive link 354b1 rotates to point forward.

[0543] Since the other end of the first drive link 354a1 is connected to the second handle body 3112 through the second movable pin Pm2, and thus can rotate relative to it, the rotational force transmitted through the other end of the first drive link 354 can be transmitted to the second handle body 3112 through the second movable pin Pm2.

[0544] Furthermore, since the other end of the second drive link 354b1 is connected to the third handle body 3113, it can rotate relative to the second movable pin Pm2. Therefore, the rotational force transmitted through the other end of the second drive link 354b1 can be transmitted to the third handle body 3113 through the second movable pin Pm2.

[0545] Therefore, the second handle body 3112 and the third handle body 3113 can each begin to move forward toward the extended position Pd.

[0546] When the first nut 353a and the second nut 353b have moved to the predetermined position after the operation of the handle driver 35 has started, the power supply to the drive motor 351 can be stopped, and the forward movement of the pop-out handle 31 to the extended position Pd can be completed.

[0547] Figure 13 The example illustrates the state where the handle 31 stops after the forward movement to the extended position Pd is completed.

[0548] When the pop-out handle 31 is moved forward to the extended position Pd as described above, the first handle body 3111 can be fully exposed to the outside of the door 30, and the user can easily perform the operation of opening or closing the door 30 while gripping the first handle body 3111.

[0549] like Figure 12 As illustrated, a blind panel 371 that moves forward or backward in association with the movement of the first handle body 3111 can be arranged at the rear of the first handle body 3111.

[0550] As described above, when the pop-out handle 31 moves to the retracted position Pa, the opening 30e of the door 30 is completely closed by the first handle body 3111, the second handle body 3112 and the third handle body 3113.

[0551] In this regard, such as Figure 14a and Figure 14b As shown, when the pop-up handle 31 moves to the retracted position Pa, the blind panel 371 can be pressed by the first handle body 3111, moving horizontally to the rearmost position and stopping.

[0552] When the blind panel 371 stops at its rearmost position, the compression springs 374, which are respectively arranged between the blind panel 371 and the first support 372 and between the blind panel 371 and the second support 373, are compressed to the maximum extent, and the maximum restoring force of the compression springs 374 acts on the rear surface of the blind panel 371.

[0553] Therefore, by compressing the maximum restoring force of the spring 374, the front surface 3711a of the blind panel 371 can be kept in close contact with the first handle body 3111.

[0554] In one example, when the pop-out handle 31 begins to move forward from the retracted position Pa toward the extended position Pd, the restoring force of the compression spring 374 can be applied to cause the blind panel 371 to move forward horizontally together with the first handle body 3111 from the rearmost position.

[0555] After the pop-out handle 31 begins to move forward from the retracted position Pa toward the extended position Pd, the blind panel 371 moves together with the pop-out handle 31 under the restoring force of the compression spring 374 until the first handle body 3111 passes through the opening 30e of the door 30 and the handle inlet 30d2 of the handle frame 30d, and completely leaves the inlet 30d2 of the door 30 and the handle inlet 30d2 of the handle frame 30d.

[0556] like Figure 14c and Figure 14d As shown, when the pop-out handle 31 moves additionally, the first handle body 3111 passes through the opening 30e of the door 30 and the handle inlet 30d2 of the handle frame 30d, and passes through the position where it is completely away from the opening 30e of the door 30 and the handle inlet 30d2 of the handle frame 30d.

[0557] In this respect, when the first handle body 3111 passes through the opening 30e of the door 30 and the handle inlet 30d2 of the handle frame 30d and passes through the position where it is completely away from the opening 30e of the door 30 and the handle inlet 30d2 of the handle frame 30d, the blind panel 371 can move to the foremost position and stop at the foremost position.

[0558] In other words, when the panel body 3711 moves to the foremost position, the flange 3712 integrally formed with the blind panel 371 may come into contact with and collide with the rear edge of the inlet rib 30d3 of the handle frame 30d, so the panel body 3711 may stop at the foremost position.

[0559] As described above, the front surface 3711a of the blind panel 371 can be released from its state of close contact with the first handle body 3111 at the foremost position of the panel body 3711 while separating from the first handle body 3111.

[0560] Furthermore, when the panel body 3711 stops at the foremost position, the compression springs 374 arranged between the blind panel 371 and the first support 372 and between the blind panel 371 and the second support 373 are in a state of minimum compression. Therefore, the minimum restoring force of the compression springs 374 acts on the rear surface of the blind panel 371.

[0561] In other words, the drive load on the drive motor 351 is at its maximum when the pop-out handle 31 is initially driven from the retracted position Pa toward the extended position Pd.

[0562] In this respect, the compression spring 374 helps to push the ejector handle 31 toward the extended position Pd. That is, the pressing force of the compression spring 374 can be transmitted to the ejector handle 31 until... Figure 14b and Figure 14c The state shown. In Figure 14d In the state shown, the pop-up handle 31 moves toward the extended position Pd solely by the driving force of the drive motor 351.

[0563] As described above, when the blind panel 371 is moved to the foremost position, the opening 30e of the front panel 30a and the handle inlet 30d2 of the handle frame 30d are covered by the blind panel 371.

[0564] However, the opening 30e of the front panel 30a and the handle inlet 30d2 of the handle frame 30d are not completely covered by the blind panel 371.

[0565] More specifically, such as Figure 14e As shown, a vertical gap can be formed between the inlet rib 30d3 of the handle frame 30d and the blind panel 371.

[0566] In this respect, as illustrated in the figure, the curved portion of the front panel 30a of the door 30 is inserted into the handle inlet 30d2 of the handle frame 30d.

[0567] Therefore, in order to minimize interference with the curved portion of the front panel 30a, the vertical gap can be formed to have a width greater than the thickness of the front panel 30a.

[0568] Because the vertical gap is formed to the extent that the curved portion of the front panel 30a can be inserted into the vertical gap, friction can be minimized when the pop-out handle 31 and the blind panel 371 move, and when viewed from the outside, a sense of unity can be formed between the front panel 30a and the front end surface 3711a of the blind panel 371.

[0569] In addition, such as Figure 14e As shown, when the blind panel 371 moves to the foremost position, the front surface 3711a of the blind panel 371 can stop, while forming a continuous surface with the front surface of the front panel 30a of the door 30.

[0570] At this point, a state can be formed in which no step is formed between the front panel 30a of the door 30 and the front surface 3711a of the blind panel 371.

[0571] However, alternatively, the shape of the front surface 3711a of the blind panel 371 can be determined such that the front panel 30a of the door 30 and the front surface 3711a of the blind panel 371 form a continuous surface, but a step is formed between the front panel 30a of the door 30 and the front surface 3711a of the blind panel 371.

[0572] More specifically, such as Figure 14f and Figure 14g As shown, the front surface 3711a of the blind panel 371 can be formed as a concave surface that is recessed from the front panel 30a to the rear.

[0573] For example, such as Figure 14f As shown, the front surface 3711a of the blind panel 371 can be formed as a concave surface including an inclined surface and a vertical surface.

[0574] In addition, such as Figure 14g As shown, for example, the front surface 3711a of the blind panel 371 can be formed as a concave surface including a curved surface with a predetermined curvature.

[0575] Since the front surface 3711a of the blind panel 371 is recessed rearward relative to the front panel 30a, the through area of ​​the pop-out handle 31, which is limited to the rear of the first handle body 3111, can be additionally ensured after the pop-out handle 31 moves to the extended position Pd.

[0576] Therefore, additional gripping space can be ensured for the user, thereby improving user convenience and stability.

[0577] Alternatively, when the blind panel 371 is moved to the foremost position, as... Figure 14h As shown, it can stop at a position that protrudes a predetermined amount from the front surface of the front panel 30a of the door 30.

[0578] In the same case, the corner where the front surface 3711a of the blind panel 371 connects to the front panel 30a can be formed with a beveled surface that is curved or inclined. Therefore, a sense of unity or connection can be maintained between the front surface 3711a of the blind panel 371 and the front panel 30a.

[0579] Therefore, such as Figure 14a As illustrated, the width Wb between the front end surface 3711a of the blind panel 371 and the flange 3712 in the front-rear direction (FR direction) can be set to be slightly greater than or equal to the width Wr of the entrance rib 30d3 in the front-rear direction (FR direction).

[0580] [Detailed configuration and operation of the position deviation adjuster]

[0581] In the following text, reference will be made to Figures 15 to 17 The detailed configuration and operation of the position deviation adjusters 356a and 356b arranged in the dishwasher 1 according to an embodiment of the present disclosure are described.

[0582] As described above, in this disclosure, the rotational driving force for the reciprocating motion of the ejector handle 31 is generated by a single drive motor 351.

[0583] Therefore, during the reciprocating motion of the pop-out handle 31, there is a high possibility that the positional deviation between the second handle body 3112 and the third handle body 3113 may occur.

[0584] Position deviation adjusters 356a and 356b are used to minimize the position deviation between the second handle body 3112 and the third handle body 3113.

[0585] More specifically, as illustrated in the figure, the position deviation adjusters 356a and 356b may include a first deviation adjuster 356a that adjusts the position of the second handle body 3112 in the forward / backward (FR) direction.

[0586] In addition, the position deviation adjusters 356a and 356b may include a second deviation adjuster 356b for adjusting the position of the third handle body 3113 in the front-rear direction (FR direction).

[0587] Examplely, the first deviation adjuster 356a may include a first shaft 356a1 having one end connected to the second handle body 3112 in a relatively rotatable manner.

[0588] In addition, the first deviation adjuster 356a may include a first second shaft 356a2, which has one end connected to the handle frame 30d in a relatively rotatable manner.

[0589] In addition, the first deviation adjuster 356a may include a first spring 356a3, which applies a restoring force to increase the distance between one end of the first shaft 356a1 and one end of the first second shaft 356a2.

[0590] The first axis 356a1 and the first second axis 356a2 can be connected to each other in a telescopic manner.

[0591] For telescopic connection, the first shaft 356a1 may be a hollow shaft, and the first second shaft 356a2 for connecting to and inserting into the first shaft 356a1 may be a hollow rib.

[0592] The first spring 356a3 can be arranged inside the first shaft 356a1 in a compressed state.

[0593] In this respect, one end of the first shaft 356a1 can be connected to the second handle body 3112 by a movable pin so that they can rotate relative to each other.

[0594] More specifically, one end of the first shaft 356a1 can be connected to the upper end of the second movable pin Pm2 so as to rotate relative to the first drive link 354a1.

[0595] Therefore, when the second handle body 3112 moves, one end of the first shaft 356a1 can move together with the second movable pin Pm2 in the front-rear direction (FR direction).

[0596] Therefore, a ring having a circular hole defined therein for the second movable pin Pm2 to be inserted into can be arranged at one end of the first shaft 356a1.

[0597] Furthermore, one end of the first and second shafts 356a2 can be connected to the upper wall 30d12 of the handle frame 30d via a fixing pin Pf (not shown) so that they can rotate relative to each other.

[0598] Therefore, one end of the first and second shafts 356a2 can be in a state in which only relative rotation is possible.

[0599] In this respect, when the pop-out handle 31 stops at the retracted position Pa, one end of the first first shaft 356a1 is positioned behind one end of the first second shaft 356a2 in the front-rear direction (FR direction).

[0600] Therefore, when the pop-out handle 31 stops at the retracted position Pa, the first deviation adjuster 356a applies force to push the second handle body 3112 backward.

[0601] In one example, the second deviation adjuster 356b can be arranged at a position symmetrical to the position of the first deviation adjuster 356a relative to the vertical surface of the pop-out handle 31 which is equally divided along the horizontal direction, and is formed in a shape symmetrical to its shape.

[0602] Therefore, similar to the first deviation adjuster 356a, the second deviation adjuster 356b may include a second first shaft 356b1 and a second second shaft 356b2 that are telescopically connected to each other, and the second spring 356b3 may be arranged inside the second first shaft 356b1 in a compressed state.

[0603] Furthermore, one end of the second first shaft 356b1 can be connected to the upper end of the aforementioned second movable pin Pm2 so as to rotate relative to the second drive link 354b1.

[0604] Therefore, when the third handle body 3113 moves, one end of the second first shaft 356b1 can move together with the second movable pin Pm2 in the front-rear direction (FR direction).

[0605] Therefore, a ring having a circular hole into which the second movable pin Pm2 can be inserted can be arranged at one end of the second first shaft 356b1.

[0606] Furthermore, one end of the second shaft 356b2 can be connected to the upper wall 30d12 of the handle frame 30d via a fixing pin Pf (not shown) so that it can rotate relative to the handle frame 30d.

[0607] Therefore, one end of the second shaft 356b2 can be in a state in which only relative rotation is possible.

[0608] In this respect, in the same manner as the first deviation adjuster 356a, when the pop-out handle 31 stops at the retracted position Pa, one end of the second first shaft 356b1 is arranged behind one end of the second second shaft 356b2 in the front-rear direction (FR direction).

[0609] Therefore, when the pop-out handle 31 stops at the retracted position Pa, the second deviation adjuster 356b applies force to push the third handle body 3113 backward toward the second handle body 3112.

[0610] However, one end of the first first shaft 356a1 of the first deviation adjuster 356a can move together with the second handle body 3112 in the front-rear direction (FR direction), but one end of the first second shaft 356a2 of the first deviation adjuster 356a cannot move in the front-rear direction (FR direction).

[0611] Similarly, one end of the second first shaft 356b1 of the second deviation adjuster 356b can move together with the third handle body 3113 in the front-rear direction (FR direction), but one end of the second second shaft 356b2 of the second deviation adjuster 356b cannot move in the front-rear direction (FR direction).

[0612] Therefore, the direction of the force applied by the first deviation adjuster 356a and the direction of the force applied by the second deviation adjuster 356b can vary depending on the position of the second handle body 3112 in the front-rear direction (FR direction) and the position of the third handle body 3113 in the front-rear direction (FR direction).

[0613] More specifically, the range of motion of the pop-up handle 31 may include being limited to Figure 15 and Figure 16 The first range of motion between the retracted position Pa and the intermediate position illustrated in the figure, in which the first deviation adjuster 356a and the second deviation adjuster 356 are arranged parallel to the extension direction of the first handle body 3111.

[0614] Furthermore, the range of motion of the pop-out handle 31 may include being limited to Figure 16 and Figure 17 The second range of motion between the intermediate position and the extended position Pd illustrated herein, wherein the first deviation adjuster 356a and the second deviation adjuster 356b are arranged parallel to the extension direction of the first handle body 3111 in the intermediate position.

[0615] When the pop-out handle 31 is in the first range of motion, the first deviation adjuster 356a applies a backward thrust F_r to the second handle body 3112, and the second deviation adjuster 356b applies a backward thrust F_r to the third handle body 3113.

[0616] Therefore, when a positional deviation occurs between the second handle body 3112 and the third handle body 3113 within the first range of motion, a greater force is applied to either the second handle body 3112 or the third handle body 3113, which has already moved further forward, through the first deviation adjuster 356a and the second deviation adjuster 356b.

[0617] Therefore, the positional deviation between the second handle body 3112 and the third handle body 3113 can be effectively adjusted within the first range of motion.

[0618] In this respect, when the pop-out handle 31 passes through the aforementioned intermediate position and moves into the second range of motion, the force of the first deviation adjuster 356a and the force of the second deviation adjuster 356b change from a backward pushing force to a forward pushing force.

[0619] Therefore, when the pop-out handle 31 is in the second range of motion, the first deviation adjuster 356a applies a forward thrust F_f to the second handle body 3112, and the second deviation adjuster 356b applies a forward thrust F_f to the third handle body 3113.

[0620] As a result, when a positional deviation occurs between the second handle body 3112 and the third handle body 3113 within the second range of motion, a greater force is applied to either the second handle body 3112 or the third handle body 3113, which has already moved forward less, through the first deviation adjuster 356a and the second deviation adjuster 356b.

[0621] Therefore, the positional deviation between the second handle body 3112 and the third handle body 3113 can be effectively adjusted within the first range of motion.

[0622] Although the present disclosure has been described above with reference to the accompanying drawings, it is not limited to the embodiments and drawings disclosed herein, and it will be apparent to those skilled in the art that various modifications can be made within the scope of the technical concept of the present disclosure. Furthermore, even though the effects of configurations according to the present disclosure are not explicitly described or illustrated in the description of embodiments of the present disclosure, it should be naturally understood that the predictable effects of such configurations are to be expected.
