Description

Technical Field

[0007]

[0001] The present invention relates to a dishwasher and household electrical appliances. More specifically, it is configured such that the handle automatically protrudes forward from the door only when necessary, such as when opening and closing the door, to prevent external foreign objects such as dust from flowing into the inside of the door, thereby preventing the internal space of the door from being contaminated and greatly improving the convenience for the user. The present invention relates to a dishwasher and household electrical appliances.

Background Art

[0002] A dishwasher is a device that sprays cleaning water such as water onto dishes, cooking utensils, etc., which are objects to be cleaned stored inside, for cleaning. At this time, the cleaning water used for cleaning may contain a detergent.

[0003] Generally, a dishwasher is composed of a washing tank that forms a washing space, a storage part that houses objects to be cleaned inside the washing tank, a spraying arm that sprays cleaning water into the storage part, and a sump that stores water and supplies the cleaning water to the spraying arm.

[0004] By using these dishwashers, it is possible to reduce the time and effort required for washing dishes, such as dishes, after a meal, which contributes to the convenience of the user.

[0005] Normally, a dishwasher is configured to be able to perform a washing process for washing objects to be cleaned, a rinsing process for rinsing the objects to be cleaned, and a drying process for drying the objects to be cleaned after washing and rinsing are completed.

[0006] Before performing such processes, and after the processes are completed, in order to store the dishes inside the dishwasher and to take out the dishes that have been washed and dried, the user must perform the process of opening and closing the door.

[0007] ' To facilitate the opening and closing of such doors, they are generally equipped with handles that can be grasped by the user.

[0008] In this regard, European Patent Publication No. 2096360 (Prior Document 1) discloses a dishwasher in which a pop-up handle is provided on the door that protrudes from the front surface of the door when gripped for opening and closing the door. [Prior art documents] [Patent Documents]

[0009] [Patent Document 1] European Patent Registration Publication No. 2096360 [Overview of the Initiative] [Problems that the invention aims to solve]

[0010] The handle disclosed in the aforementioned prior art 1 is configured to manually extend by rotating from an unused position, where the amount of protrusion from the door is minimal, toward a usable position where the user can grasp it.

[0011] Therefore, the handle disclosed in Prior Art 1 may cause some inconvenience to the user because it requires the user to manually move it from the unused position to the used position, and then, once the door is opened or closed, to move it again manually from the used position back to the unused position.

[0012] Furthermore, the handle disclosed in Prior Art 1, while initially protruding in the usage position, remains fixed in the protruding position unless the user moves it further to the non-usage position.

[0013] Therefore, the handle disclosed in Prior Art 1 has the problem of negating the advantages of a pop-up handle because it is essentially always maintained in the same state as a protruding handle.

[0014] Furthermore, when the handle disclosed in Prior Art 1 protrudes to the usage position, it may create a state in which the internal space of the door, which was obstructed in the non-used position, is at least partially exposed to the outside.

[0015] Therefore, the handle disclosed in Prior Art 1 has a structure that allows external foreign matter such as dust to enter and accumulate through the exposed part when the handle is moved to the position of use, which has the problem of potentially causing hygiene problems.

[0016] Furthermore, the handle disclosed in Prior Art 1, when moved to the use position, may expose an opening with a considerably large cross-sectional area corresponding to the size of the handle to the outside. This means that an external object with a considerably large volume may be introduced into the door, which makes it very likely that damage will occur to components placed inside the door.

[0017] Furthermore, the handle disclosed in Prior Art 1 has the problem that, when the handle is moved to the usage position, an opening with a considerably large cross-sectional area corresponding to the size of the handle may be exposed to the outside, thereby creating a situation in which the user can observe the interior space of the door, which may act as an element that hinders the user's aesthetic sensibilities.

[0018] The present invention was devised to solve the problems of the prior art, and its primary objective is to provide a dishwasher and home appliance that are configured so that the handle automatically extends forward from the door only when necessary, such as when opening or closing the door, thereby preventing external foreign matter such as dust from entering the inside of the door, thus preventing contamination of the interior space of the door, and greatly improving user convenience.

[0019] Furthermore, a second objective of the present invention is to provide a dishwasher and home appliances in which the handle drive unit that moves 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 drive unit and improving the usability of the space inside the door.

[0020] Furthermore, a third objective of the present invention is to provide a dishwasher and home appliances that can prevent damage to the handle and an increase in the load on the drive motor due to positional deviation, by configuring the handle drive unit to include a position deviation adjustment unit to adjust the deviation in the amount of movement of both ends of the handle that may occur when the handle is driven by a single drive motor.

[0021] Furthermore, the fourth objective of the present invention is to provide a dishwasher and home appliances that include a blind module that can shield the door opening when the pop-up handle is moved to the deployed position, thereby preventing contamination of the interior space of the door by foreign matter that may enter through the door opening, preventing malfunction and damage to the drive unit due to the influx of foreign matter, and preventing the user's aesthetic sensibilities from being hindered by blocking the observation of the interior space of the door.

[0022] Furthermore, a fifth objective of the present invention is to provide a dishwasher and home appliances that can further enhance the user's aesthetic sensibilities by forming the front end surface of the blind module that shields the door opening to have a sense of unity with the front surface of the door.

[0023] The objectives of the present invention are not limited to those mentioned above. Other objectives and advantages of the present invention not mentioned can be understood from the following description and more clearly from the embodiments of the present invention. Furthermore, it is readily apparent that the objectives and advantages of the present invention can be achieved by the means and combinations thereof described in the claims. [Means for solving the problem]

[0024] The dishwasher according to the present invention includes a tub that forms a washing space with an open front surface, a door that opens and closes the front surface where the tub is open, a handle that is disposed to be reciprocally movable back and forth between a deployed position protruding forward from the door and a retracted position at least partially accommodated inside the door, and a handle driving unit that is disposed inside the door and reciprocates the handle from the retracted position toward the deployed position or from the deployed position toward the retracted position. The handle driving unit may include a driving motor that generates a rotational driving force provided respectively on one end side and the other end side of the handle.

[0025] Further, the driving motor may include a first output shaft extending toward one end of the handle and a second output shaft extending toward the other end of the handle.

[0026] Further, a first interval is formed between the first output shaft and one end of the handle, and a second interval is formed between the second output shaft and the other end of the handle. The first interval and the second interval may be the same as each other.

[0027] Further, the handle driving unit may include a first motion conversion unit that converts the rotational driving force transmitted from the first output shaft into a reciprocating driving force back and forth, and a second motion conversion unit that converts the rotational driving force transmitted from the second output shaft into a reciprocating driving force back and forth.

[0028] Further, the first motion conversion unit and the second motion conversion unit may be arranged at positions symmetric to each other with respect to a vertical plane that equally divides the handle.

[0029] Further, the first motion conversion unit and the second motion conversion unit may be shaped symmetrically with respect to a vertical plane that equally divides the handle.

[0030] A dishwasher further comprising a position deviation adjustment unit that minimizes the position deviation in the front-rear direction that occurs between the front-rear position of one end of the handle and the front-rear position of the other end of the handle during the process in which the handle moves back and forth between the extended position and the retracted position.

[0031] The door may further include a handle frame disposed inside the door and supporting the handle so as to be able to move back and forth, and the position deviation adjustment unit may include a first deviation adjustment unit, one end of which is rotatably connected relative to one end of the handle and the other end of which is rotatably connected relative to the handle frame, and a second deviation adjustment unit, one end of which is rotatably connected relative to the other end of the handle and the other end of which is rotatably connected relative to the handle frame.

[0032] Furthermore, the first deviation adjustment unit can apply a force to one end of the handle that pushes it backward or forward depending on the front-rear position of the handle, and the second deviation adjustment unit can apply a force to the other end of the handle that pushes it backward or forward depending on the front-rear position of the handle.

[0033] Furthermore, when the handle is moved to the retracted position, the first deviation adjustment unit can apply a force pushing backward to one end of the handle, and the second deviation adjustment unit can apply a force pushing backward to the other end of the handle.

[0034] Furthermore, when the handle is moved to the deployed position, the first deviation adjustment unit can apply a forward pushing force to one end of the handle, and the second deviation adjustment unit can apply a forward pushing force to the other end of the handle.

[0035] Furthermore, as the handle passes through an intermediate position formed between the retracted position and the extended position, the force of the first deviation adjustment unit and the force of the second deviation adjustment unit may be switched from a direction of pushing backward to a direction of pushing forward.

[0036] Furthermore, when the handle is moved to the deployed position, the door further includes a blind module that obscures an opening formed through the door for the handle to pass through, the blind module moving forward in conjunction with the movement of the handle while obscuring the opening.

[0037] On the other hand, the dishwasher according to the present invention includes a tab that forms a washing space with an open front surface, a door that opens and closes the front surface of the tab, a handle that is arranged to move horizontally back and forth between an extended position that protrudes forward from the door and a retracted position in which at least a portion is housed inside the door, and a handle drive unit arranged inside the door that moves the handle horizontally from the retracted position toward the extended position or from the extended position toward the retracted position, wherein the handle drive unit includes a drive motor that generates a rotational driving force provided to the end side of the handle.

[0038] Furthermore, the drive motor may include an output shaft that extends horizontally toward the end of the handle.

[0039] Furthermore, the handle drive unit may include a motion conversion unit that converts the rotational driving force transmitted from the output shaft into forward and backward horizontal driving force.

[0040] Furthermore, the handle drive unit may further include a position deviation adjustment unit that minimizes the longitudinal position deviation that occurs between the longitudinal position of one end of the handle and the longitudinal position of the other end of the handle during the process in which the handle moves horizontally back and forth between the extended position and the retracted position.

[0041] The door may further include a handle frame positioned inside the door to support the handle so that it can move horizontally forward and backward, and the position deviation adjustment unit may have one end rotatably connected to one end of the handle and the other end rotatably connected to the handle frame.

[0042] Furthermore, when the handle is moved to the retracted position, the position deviation adjustment unit can apply a force to one end of the handle in a backward direction, and when the handle is moved to the extended position, the position deviation adjustment unit can apply a force to one end of the handle in a forward direction.

[0043] On the other hand, the home appliance according to the present invention includes a case that forms an outer shape, a door that opens and closes an internal space formed inside the case, a handle that is arranged to be reciprocally movable between an extended position that protrudes forward from the door and a retracted position in which at least a part of it is housed inside the door, and a handle drive unit arranged inside the door that reciprocates the handle from the retracted position toward the extended position or from the extended position toward the retracted position, and the handle drive unit may include a drive motor that generates rotational driving force provided to the left end side and the right end side of the handle. [Effects of the Invention]

[0061] The present invention will be described below with reference to drawings showing the configuration according to one embodiment of the present invention.

[0062] [General structure of a dishwasher] The general structure of a dishwasher 1 according to one embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0063] Figure 1 is a front perspective view showing the dishwasher 1 according to the present invention, and Figure 2 is a simplified cross-sectional view showing the internal structure of the dishwasher 1 according to the present invention.

[0064] As shown in Figures 1 and 2, the dishwasher 1 according to the present invention may include a case 10 that forms the outer shape.

[0065] Furthermore, the dishwasher 1 according to the present invention may include a tab 20 installed inside the case 10, forming a washing space 21 in which objects to be washed are washed, and having an open front surface.

[0066] Furthermore, the dishwasher 1 according to the present invention may include a door 30 that opens and closes the front surface on which the tab 20 is open.

[0067] Furthermore, the dishwasher 1 according to the present invention may include a drive unit 40 located at the bottom of the tub 20 that supplies, collects, circulates, and drains washing water for washing objects to be washed.

[0068] Furthermore, the dishwasher 1 according to the present invention may include a storage section 50 that is detachably provided in the internal washing space 21 of the tab 20 and securely holds the items to be washed.

[0069] Furthermore, the dishwasher 1 according to the present invention may include a spray unit 60 installed adjacent to the storage unit 50 for spraying washing water to wash the objects to be washed.

[0070] In this case, the items to be washed that are secured in the storage section 50 may be, for example, dishes, plates, spoons, chopsticks and other tableware, as well as other cooking utensils. Hereafter, unless otherwise specified, the items to be washed will be referred to as tableware.

[0071] The tab 20 may be formed in a box shape with its front surface completely open, which corresponds to a configuration known as a washing tank.

[0072] A cleaning space 21 is formed inside the tab 20, and the open front surface may be opened and closed by the door 30.

[0073] The tab 20 may be formed by press working from a metal sheet material that is resistant to high temperatures and moisture, such as a stainless steel sheet material.

[0074] Furthermore, the inner surface of the tab 20 may be provided with a number of brackets intended to support and install functional components such as the storage section 50 and the spray section 60, which will be described later, inside the tab 20.

[0075] On the other hand, the drive unit 40 may include a sump 41 for storing cleaning water.

[0076] Furthermore, the drive unit 40 may include a sump cover 42 that separates the sump 41 from the tab 20.

[0077] Furthermore, the drive unit 40 may include a water supply unit 43 that supplies cleaning water to the sump 41 from the outside.

[0078] Furthermore, the drive unit 40 may also include a drain unit 44 for discharging the cleaning water from the sump 41 to the outside.

[0079] The drive unit 40 may also include a cleaning pump 45 and a supply channel 46 for supplying cleaning water from the sump 41 to the injection unit 60.

[0080] The sump cover 42 is positioned above the sump 41 and serves to separate the tab 20 from the sump 41.

[0081] Furthermore, the sump cover 42 may be provided with multiple recovery holes to recover the cleaning water sprayed into the cleaning space 21 via the spray unit 60 into the sump 41.

[0082] In other words, the washing water sprayed towards the dishes by the spray unit 60 may fall to the bottom of the washing space 21 and be collected in the sump 41 via the sump cover 42.

[0083] The cleaning pump 45 is provided on one side of the sump 41 and is responsible for pressurizing the cleaning water and supplying it to the spray unit 60.

[0084] One end of the cleaning pump 45 may be connected to the sump 41, and the other end may be connected to the supply channel 46. The cleaning pump 45 may include an impeller 451 and a motor 453, etc. When power is supplied to the motor 453, the impeller 451 rotates, and the cleaning water in the sump 41 is pressurized and then supplied to the spray section 60 via the supply channel 46.

[0085] Although not shown, the washing pump 45 may be equipped with a washing water heater to heat the washing water supplied during the washing or heated rinsing process.

[0086] On the other hand, the supply channel 46 can play a role in selectively supplying the cleaning water supplied from the cleaning pump 45 to the injection section 60.

[0087] As an example, the supply channel 46 may include a first supply channel 461 connected to the lower injection arm 61 and a second supply channel 463 connected to the upper injection arm 62 and the top nozzle 63.

[0088] The supply channel 46 may also be equipped with a supply channel switching valve 465 that selectively opens and closes the supply channels 461 and 463.

[0089] In this case, the supply flow path switching valve 465 may be controlled to open each supply flow path 461, 463 sequentially, or to open them simultaneously.

[0090] Meanwhile, the spray unit 60 performs the function of spraying washing water onto dishes and other items stored in the storage unit 50.

[0091] More specifically, the spray unit 60 may include a lower spray arm 61 located below the tab 20 that sprays cleaning water onto the lower rack 51.

[0092] Furthermore, the spray unit 60 may include an upper spray arm 62 positioned between the lower rack 51 and the upper rack 52, which sprays cleaning water onto the lower rack 51 and the upper rack 52.

[0093] Furthermore, the spray unit 60 may include a top nozzle 63 located above the tab 20 that sprays cleaning water onto the top rack 53 or upper rack 52.

[0094] In particular, the lower spray arm 61 and the upper spray arm 62 are rotatably provided in the washing space 21 of the tab 20, and can spray washing water while rotating toward the dishes in the storage section 50.

[0095] The lower spray arm 61 may be rotatably supported above the sump cover 42 so that it can spray cleaning water toward the lower rack 51 while rotating beneath the lower rack 51.

[0096] Furthermore, the upper spray arm 62 may be rotatably supported by a spray arm holder 467 so that it can spray cleaning water while rotating between the lower rack 51 and the upper rack 52.

[0097] On the other hand, although not shown, the lower surface 25 of the tab 20 may be further provided with means for switching the cleaning water sprayed from the lower spray arm 61 upward (U-direction) in order to improve cleaning efficiency.

[0098] Since the detailed configuration of the injection unit 60 can be based on configurations already known in the industry, a detailed explanation of the specific configuration of the injection unit 60 will be omitted below.

[0099] On the other hand, the washing space 21 may also be equipped with a storage section 50 for storing dishes.

[0100] The storage compartment 50 is provided inside the tab 20 and is retractable through the open front surface of the tab 20.

[0101] As an example, Figure 2 shows an embodiment in which a storage section is provided, including a lower rack 51 located below the tab 20, in which relatively large dishes can be stored; an upper rack 52 located above the lower rack 51, in which medium-sized dishes can be stored; and a top rack 53 located above the tab 20, in which small dishes and the like can be stored. The present invention is not limited thereto, but will be described based on an embodiment of a dishwasher 1 equipped with three storage sections 50 as shown in the figure.

[0102] These lower rack 51, upper rack 52, and top rack 53 may each be configured to be pulled out to the outside through an open front surface with tabs 20.

[0103] Therefore, guide rails (not shown) can be provided on both side walls that form the inner circumferential surface of the tab 20, and as an example, the guide rails may include an upper rail, a lower rail, and a top rail.

[0104] Wheels may be provided at the bottom of the lower rack 51, upper rack 52, and top rack 53. Users can easily store dishes in the lower rack 51, upper rack 52, and top rack 53, or remove washed dishes from them, by pulling them out through the front of the tab 20.

[0105] The guide rail may be a simple rail-shaped fixed guide rail to guide the pulling out and inserting of the storage section 50, or it may be an extendable guide rail that guides the pulling out and inserting of the storage section 50, and the pulling distance increases as the storage section 50 is pulled out.

[0106] On the other hand, the door 30 serves the purpose of opening and closing the front surface through which the aforementioned tab 20 is open.

[0107] A hinge (not shown) may be provided at the lower part of the open front surface as a means for opening and closing the door 30. The door 30 may be opened by rotating around the hinge as an axis of rotation.

[0108] Here, the outer surface of the door 30 may be provided with a handle 31 for opening the door 30 and a control panel 32 for controlling the operation of the dishwasher 1.

[0109] As shown in the figure, the control panel 32 may include a display 33 that visually displays information such as the current operating status of the dishwasher 1, and a button section 34 that includes selection buttons for inputting the user's course selection operation, and a power button for inputting the user's operation to turn the dishwasher on and off.

[0110] On the other hand, the rear panel forming the inner surface of the door 30 forms one surface of the tab 20 when the door 30 is closed, and when the door 30 is fully open, it can form a support surface on which the lower rack 51 of the storage compartment 50 can be supported.

[0111] Therefore, when the door 30 is fully open, it is preferable that the rear panel of the door 30 forms a horizontal plane in the same direction as the guide rail that guides the lower rack 51 extends.

[0112] On the other hand, unlike conventional models, the handle 31 of the dishwasher 1 according to the present invention may be configured to be at least partially housed inside the door 30 when not in use, and to automatically protrude forward from the door 30 when necessary for opening and closing the door 30.

[0113] In this way, since it is provided so as to be able to protrude and move from the inside of the door 30 to the outside of the door 30, it can be called by various names such as pop-up handle, retractable handle, etc.

[0114] Hereinafter, the handle movably provided on the door 30 of a dishwasher 1 according to one embodiment of the present invention will be referred to as the pop-up handle 31.

[0115] The detailed configuration of the pop-up handle 31 will be described later with reference to Figure 3 and subsequent figures.

[0116] On the other hand, although not shown, the rear panel forming the inner surface of the door 30 may further be equipped with a detergent supply device for automatically supplying detergent into the inside of the tub 20.

[0117] Furthermore, a door position sensing unit 36 ​​may be provided on the outer side of the upper surface of the tab 20 to sense whether the door 30 is in a closed or open state. For example, the door position sensing unit 36 ​​may include a door position sensor (S_d) or a latch sensor that senses the position of a door latch, which is not shown.

[0118] On the other hand, the lower part of the tab 20 may be provided with a drying air supply unit 80 to generate and supply high-temperature or low-temperature drying air to the cleaning space 21 inside the tab 20.

[0119] As shown in the figure, the drying air supply unit 80 may include a filter member 883 for filtering outside air, a blower fan 825 for generating a drying airflow, a heater 84 for heating the drying airflow, and an airflow guide 83 disposed inside the tab 20 for guiding the drying airflow.

[0120] The lower surface of the tab 20 may be provided with a drying air supply hole so that the high-temperature drying air generated by the drying air supply unit 80 can be introduced into the interior of the tab 20.

[0121] By supplying high-temperature or low-temperature drying air from these drying air supply units 80 into the interior of the tab 20 during the drying process, the drying efficiency and sterilization effect on tableware can be significantly improved compared to conventional methods.

[0122] On the other hand, the humid airflow supplied to the inside of the tub 20 to dry the dishes may be configured to be discharged to the outside, and the discharge of the airflow can be done by partially opening the door 30 or by a separate exhaust means (not shown).

[0123] [External shape and operating method of the pop-up handle] The external shape and operating method of the pop-up handle 31 provided on the door 30 of a dishwasher 1 according to one embodiment of the present invention will be described in detail below with reference to Figures 3 to 5b.

[0124] In the following description, as an example, we will explain based on an embodiment in which the pop-up handle 31 and the configuration related to the pop-up handle 31 are located inside the door 30 that constitutes the dishwasher 1.

[0125] However, the present invention is not limited thereto, and the pop-up handle 31 and its configuration described below can also be similarly applied to home appliances such as ovens, refrigerators, dryers, washing machines, or clothing management devices, in which the internal space of a case performing a specific function is opened and closed via a door.

[0126] However, these oven appliances, refrigerators, dryers, washing machines, or clothing management appliances have different purposes and functions than the dishwasher 1 according to the present invention, and are configured to operate under different operating conditions and environments.

[0127] In particular, since oven appliances operate in high-temperature environments, the pop-up handle and handle drive mechanism must be made of materials that can withstand high temperatures. Furthermore, although the oven door provides space for the pop-up handle and drive mechanism, some parts use heat-resistant glass material. Therefore, the pop-up handle and drive mechanism must be in harmony with this material, and additional measures may be taken to ensure durability and safety in high-temperature environments.

[0128] On the other hand, refrigerators have shelves, storage space, and insulation inside the door, which can limit how space can be used.

[0129] Therefore, in order to install a pop-up handle and handle drive mechanism, it may be necessary to redesign the internal structure of the door or to secure space that allows for installation without interfering with the existing structure. In the case of a refrigerator, since the pop-up handle is located on a door that is opened and closed many times, durability and waterproof design may be essential.

[0130] With this in mind, the motor and electrical components that drive the pop-up handle may be located in the empty space formed inside the refrigerator door and must be designed to be compatible with the refrigerator's power supply structure. However, the design must ensure that it does not interfere with the internal insulation of the door and the structure of the shelves, and measures to ensure waterproofing and durability may be added.

[0131] On the other hand, dryers are exposed to high temperatures and humidity. The pop-up handle and handle drive mechanism must be made of materials that can withstand high temperatures, and measures must be taken to prevent damage from the internal heat of the dryer.

[0132] On the other hand, in the case of a washing machine, the back of the door contains tubs for water, detergent, and laundry. Therefore, when installing a pop-up handle and handle drive unit on a washing machine door, there is a high possibility of exposure to water and detergent, so waterproof and dustproof design may be essential. In particular, the handle drive unit must be installed in a sealed space so that the electric motor and electrical components are not exposed to water, and measures must be taken to ensure durability through waterproof and dustproof design.

[0133] On the other hand, because garment care machines include a steam function, moisture can penetrate the inside of the door. Therefore, the pop-up handle and handle drive mechanism must be moisture-resistant and designed with a sealed structure to prevent water penetration. Thus, waterproof and moisture-proof measures must be added to ensure durability in a steam environment.

[0134] Considering these operating environments and conditions, in washing machines, stylers, and dryers, where there is a high probability of exposure to water and moisture, a sealed structure may be essential for the pop-up handle and handle drive mechanism.

[0135] Furthermore, since dryers and ovens must operate in high-temperature environments, the pop-up handle and handle drive mechanism must be made from heat-resistant materials.

[0136] Furthermore, the motor and electrical components that drive the handle drive unit must be positioned to efficiently utilize the internal space of the door and may be designed to avoid causing inconvenience to the user. In addition, the pop-up handle and handle drive unit must be equipped with means to ensure the safety and prevent injury to the user, and there must be a means for the user to manually open the door in the event of a malfunction.

[0137] In particular, the following description will be based on a configuration in which the pop-up handle 31 is arranged lengthwise along the left-right direction, aligned with the upper end surface of the door 30, taking into consideration the opening and closing direction of the door 30 of the dishwasher 1. However, in the case of home appliances such as refrigerators and clothing management equipment, where the opening and closing direction of the door 30 varies, the pop-up handle 31 may be arranged on the door so that its length is parallel to the up-down direction.

[0138] As described above, the door 30 of the dishwasher 1 according to one embodiment of the present invention may be equipped with a pop-up handle 31 that can move back and forth.

[0139] In this case, as mentioned above, the door 30 may be rotatably provided via a hinge portion (not shown) connected to the lower end.

[0140] However, the present invention is not limited thereto, and drawer-type doors that are configured to open and close by simply moving horizontally along the front-rear direction (FR direction) are also applicable. In the following description, an embodiment including a door 30 that is rotatable and opens and closes via a hinge connected to the lower end, as shown in the figure, will be described as an example.

[0141] Taking this into consideration, the pop-up handle 31 may be positioned as close as possible to the upper end surface of the door 30, in a position that is easily grasped by the user, as shown in Figures 3 and 4.

[0142] Alternatively, the pop-up handle 31 may be positioned to pass through the front panel 30a that forms the front surface of the door 30, so that the pop-up handle 31 can be retracted.

[0143] Furthermore, to facilitate the user's grip, the pop-up handle 31 may be arranged to align with the upper end surface of the door 30 along the left-right direction.

[0144] Furthermore, the pop-up handle 31 may be formed to have an overall U-shaped outer form to facilitate the user's grip.

[0145] If, instead, the pop-up handle 31 were formed as a simple bar that fills the opening 30e of the front panel 30a, the blind module 37 described later would become unnecessary, but it would likely cause some inconvenience when the user grips it to open the door 30.

[0146] Therefore, in order for the user to apply force to open the door 30, the pop-up handle 31 preferably has a U-shaped outer form that includes a leg area connected to the door 30 and a grip area for the user to grasp.

[0147] As a result, the pop-up handle 31 may have a through-region formed in a shape surrounded by a leg region and a grip region. Therefore, as will be described later, the internal structure of the door 30 will inevitably be exposed to the outside due to the through-region of the pop-up handle 31 and the opening 30e in the front panel 30a of the door 30. The detailed configuration of the blind module 37 for shielding the opening 30e will be described later with reference to Figure 8 and subsequent figures.

[0148] More specifically, as shown in Figure 5b, the pop-up handle 31 may include a first handle body 311 that, when moved forward, protrudes outward from the door 30 as a whole, forming a grip area that can be grasped by the user, so as to form a U-shaped outline.

[0149] Furthermore, the pop-up handle 31 may further include a second handle body 3112 connected to the left end of the first handle body 311, extending rearward and forming a leg area.

[0150] Furthermore, the pop-up handle 31 may further include a third handle body 3113 connected to the right end of the first handle body 311, extending rearward and forming a leg area.

[0151] In this case, the second handle body 3112 and the third handle body 3113 may partially protrude from the outside of the door 30 when they move forward.

[0152] Therefore, based on the illustrated embodiment, the through-region enclosed by the first handle body 311, the second handle body 3112, the third handle body 3113, and the front panel 30a of the door 30 may be formed to allow passage in the vertical direction, so that a user can insert their finger into the through-region, grasp the first handle body 311, and pull to open the door 30.

[0153] However, as mentioned above, if the pop-up handle 31 is arranged on the door so that its longitudinal direction is parallel to the vertical direction (UD direction), the through-area may be formed to allow passage in the left-right direction.

[0154] In other words, the orientation in which the pop-up handle 31 is positioned includes the diagonal direction of the door 30 and may be arranged in any region and along any direction.

[0155] In the illustrated embodiment, the second handle body 3112 and the third handle body 3113 are formed separately and are configured to be forcibly fastened to both ends of the first handle body 311 by separate fastening means such as screw bolts. However, they may also be formed integrally with the first handle body 311.

[0156] Guide blocks 3114 may be provided on the left side of the second handle body 3112 and on the right side of the third handle body 3113, respectively.

[0157] The guide block 3114 is inserted into the guide brackets 30h1 and 30h2 of the handle frame 30d, which will be described later, and plays a role in guiding the back-and-forth movement of the handle frame 30d.

[0158] Furthermore, the guide block 3114 can act as a stopper to prevent the pop-up handle 31 from moving further forward after it has finished moving to the deployed position (Pd).

[0159] Furthermore, after the pop-up handle 31 is moved to the deployed position (Pd), it can also serve to absorb the force or impact from the user acting on the second handle body 3112 and the third handle body 3113 of the pop-up handle 31 in order to open the door 30.

[0160] Taking this into consideration, the guide block 3114 may be formed from an elastic material having a predetermined elasticity.

[0161] To allow the pop-up handle 31 to be extended and retracted, a rectangular opening 30e corresponding to the outer shape of the pop-up handle 31 may be formed through the front panel 30a of the door 30 along the front-rear direction (FR direction).

[0162] The pop-up handle 31 may be arranged to move back and forth along the front-rear direction (FR direction) by the operation of the handle drive unit 35, which will be described later, passing through the opening 30e of the front panel 30a.

[0163] More specifically, the pop-up handle 31 may be arranged to move back and forth between a position moved to the furthest forward and a position moved to the furthest rear by the operation of the handle drive unit 35.

[0164] For convenience, in the following, the position where the pop-up handle 31 is moved to its furthest forward position will be defined as the deployed position (Pd), and the position where the pop-up handle 31 is moved to its furthest rear position will be defined as the retracted position (Pa).

[0165] Figure 3 shows the pop-up handle 31 moved to its rearmost position, the retracted position (Pa), and retracted into the door 30.

[0166] As shown in the figure, when the pop-up handle 31 is moved to the retracted position (Pa), the pop-up handle 31 may be retracted entirely or partially into the interior of the door 30.

[0167] In this case, for example, the pop-up handle 31 may be retracted into the interior of the door 30 by passing through the opening 30e of the door 30 as a whole.

[0168] Furthermore, when the pop-up handle 31 is moved to the retracted position (Pa), the pop-up handle 31 may be in a state where no portion protrudes forward from the front panel 30a of the door 30.

[0169] Furthermore, when the pop-up handle 31 is moved to the retracted position (Pa), the front end surface of the pop-up handle 31 can form a continuous surface with the front panel 30a of the door 30.

[0170] In other words, the front end surface of the pop-up handle 31 in the retracted position (Pa) may be parallel to the front panel 30a.

[0171] Therefore, a condition may be created in which no step is formed between the front panel 30a of the door 30 and the front end surface of the pop-up handle 31.

[0172] As a result, when the pop-up handle 31 is moved to the retracted position (Pa), the opening 30e of the front panel 30a may be completely closed.

[0173] Furthermore, when the pop-up handle 31 is moved to the retracted position (Pa), no step is formed between the front panel 30a and the front end surface of the pop-up handle 31. This fundamentally prevents the accumulation of foreign matter such as dust in the recess formed on the front surface of the door 30 or on the handle itself, as is the case in conventional designs.

[0174] On the other hand, as shown in Figure 5b, the front end surface of the pop-up handle 31 may be formed via a deco panel 315 that is provided separately from the first handle body 311, the second handle body 3112, and the third handle body 3113 that form the outer shape of the pop-up handle 31.

[0175] In this case, the decorative panel 315 may be formed of a material having the same texture and hue as the front panel 30a of the door 30.

[0176] This may create a sense of unity between the decorative panel 315 and the front panel 30a of the door 30.

[0177] Furthermore, the aesthetic appeal of the door 30 is improved, enhancing the user's aesthetic sense.

[0178] Figures 4 and 5a show the pop-up handle 31 moved from the retracted position (Pa) to the forwardmost position, the deployed position (Pd).

[0179] The process of opening and closing the door 30 of the dishwasher 1 is necessary to either place dishes that need to be washed inside or to remove dishes that have finished washing.

[0180] When it is necessary to open or close the door 30, and the user's intention to open the door 30 is confirmed, the pop-up door 30 may be automatically moved horizontally from the retracted position (Pa) to the deployed position (Pd) via the handle drive unit 35.

[0181] Therefore, the dishwasher 1 according to one embodiment of the present invention may further be provided with means for sensing the user's intention to open the door 30.

[0182] As an example, the means for sensing the user's intention to open the door 30 may include a proximity sensor (not shown).

[0183] The proximity sensor may be a sensor that can detect whether or not a user is approaching within a specific range from the door 30.

[0184] For example, the proximity sensor may include a radar sensor, an image sensor, or an infrared sensor.

[0185] To effectively determine whether a user is nearby, the proximity sensor may be positioned at least one of the upper end surface, lower end surface, or front surface of the door 30.

[0186] Furthermore, the means for sensing the user's intention to open the door 30 may include a touch sensor (not shown).

[0187] For example, the touch sensor may include a power-off type, a resistance type, or a pressure type touch sensor.

[0188] To effectively confirm the intention to open or close the door 30, a touch sensor may be placed on the pop-up handle 31.

[0189] As an example, the touch sensor may be mounted on the handle board 313 together with the light source element, as will be described later.

[0190] Once the user's intention is confirmed, the pop-up handle 31 may be automatically moved forward to the deployed position (Pd), as shown in Figures 4 and 5a.

[0191] Thus, once the pop-up handle 31 has completed its movement to the deployed position (Pd), the first handle body 311 of the pop-up handle 31 may be in a state where it is entirely exposed to the outside of the door 30.

[0192] Furthermore, once the pop-up handle 31 has completed its movement to the deployed position (Pd), it may be in a state where it can be grasped by the user.

[0193] In this case, the stroke (Ls) by which the pop-up handle 31 moves from the retracted position (Pa) to the deployed position (Pd) is, for example, 40 mm or more, but may be 50 mm or less.

[0194] Preferably, the stroke (Ls) by which the pop-up handle 31 moves from the retracted position (Pa) to the deployed position (Pd) may be 45 mm.

[0195] The determination of the stroke (Ls) of the pop-up handle 31 takes into consideration that if the stroke (Ls) is too short, such as less than 40 mm, it will be difficult for the user to grasp, and if the stroke (Ls) is too long, such as more than 50 mm, the size of the pop-up handle 31 in the front-to-back direction will be large, which may cause problems as the pop-up handle 31 will not be fully retracted into the interior of the door 30.

[0196] However, the travel stroke (Ls) of such a pop-up handle 31 is merely illustrative and may be set to vary depending on the overall size of the dishwasher 1 and the front-to-back dimensions of the door 30.

[0197] On the other hand, when the pop-up handle 31 is moved to the deployed position (Pd), the first handle body 311 of the pop-up handle 31 may exit the opening 30e of the front panel 30a of the door 30 and be exposed and protruding to the outside of the door 30 in its entirety.

[0198] As a result, the opening 30e of the front panel 30a is at least partially released from the closed state by the pop-up handle 31.

[0199] However, as will be described later, when the pop-up handle 31 is moved to the deployed position (Pd), the blind panel 371 of the blind module 37 is moved forward in conjunction with the first handle body 311.

[0200] Therefore, the opening 30e of the front panel 30a, which is opened by the movement of the pop-up handle 31, can be shielded by the blind panel 371.

[0201] Therefore, even when the pop-up handle 31 is moved to the deployed position (Pd), the opening 30e of the front panel 30a may remain closed or shielded.

[0202] This effectively prevents foreign matter such as dust from passing through the opening 30e and flowing into the interior of the door 30.

[0203] Furthermore, the blind panel 371 makes it impossible to observe the inside of the door 30 through the opening 30e in the front panel 30a.

[0204] This effectively prevents a decline in the user's sense of aesthetics.

[0205] The detailed configuration of the blind module 37, including the blind panel 371, will be described later with reference to Figures 8 to 15.

[0206] On the other hand, the pop-up handle 31 of the dishwasher 1 according to one embodiment of the present invention may be configured in such a way that the user can visually recognize that the pop-up handle 31 is being driven normally.

[0207] As an example, as shown in Figure 5b, the visual recognition means may include a handle substrate 313 positioned in front of the first handle body 311 and on which at least one light source element is mounted.

[0208] Furthermore, the visual recognition means may include a light guide plate 314 positioned in front of the handle substrate 313 to diffuse the visible light (L) generated by the light source element.

[0209] As shown in the figure, the handle substrate 313 and the light guide plate 314 may be arranged between the deco panel 315 and the first handle body 311.

[0210] Although not shown, the light source element can be any means to which power is supplied and which can generate a predetermined visible light (L), and may include, for example, an LED element.

[0211] The light guide plate 314 plays the role of diffusing the visible light (L) generated by the light source element.

[0212] More specifically, the visible light (L) generated by the light source element 3131 is introduced through the front or rear surface of the light guide plate 314, then uniformly dispersed within the light guide plate 314 and diffused toward the outer edge of the light guide plate 314.

[0213] At this time, the decorative panel 315 positioned 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, as described above.

[0214] Therefore, the visible light (L) introduced into the light guide plate 314 cannot pass through the deco panel 315 and can be projected to the outside via the outer edge of the light guide plate 314.

[0215] To project these visible light rays (L) externally, the edges of the light guide plate 314 may be exposed to the outside, as shown in Figure 5a.

[0216] In other words, the light guide plate 314 is positioned sandwiched between the decorative panel 315 and the front surface of the first handle body 311.

[0217] In this case, the outer edge of the light guide plate 314 may be positioned in a way that it is not obstructed by these elements.

[0218] Therefore, as shown in the figure, the visible light (L) generated by the light source element 3131 can be effectively projected to the outside via the outer edge of the light guide plate 314 after passing through the inside of the light guide plate 314.

[0219] Therefore, the user can effectively confirm whether the pop-up handle 31 is operating and its operating status via the visible light (L) projected through the outer edge of the light guide plate 314.

[0220] Furthermore, since visible light (L) is projected only through the outer edge of the light guide plate 314, a lighting effect similar to indirect lighting can be achieved. This enhances the aesthetic sensibility for the user.

[0221] [Detailed configuration of the handle drive unit and handle frame] The following describes in detail the configuration of the handle drive unit 35 that drives the pop-up handle 31 so that the pop-up handle 31 moves back and forth between the deployed position (Pd) and the retracted position (Pa), with reference to Figures 6 to 17.

[0222] Referring to Figures 6 to 8, the handle drive unit 35 may include a drive motor 351 to which power is supplied and which generates rotational driving force.

[0223] In this case, as mentioned above, the drive motor 351 constituting the handle drive unit 35 may be provided as a single unit.

[0224] Therefore, the rotational driving force provided to the left end and the right end of the pop-up handle 31, respectively, may be generated collectively via the drive motor 351.

[0225] Thus, by configuring the handle drive unit 35 to include only a single drive motor 351, the number of components constituting the dishwasher 1 can be reduced.

[0226] Furthermore, the space occupied by the handle drive unit 35 inside the door 30 is effectively reduced, thereby improving the usability of the space inside the door 30.

[0227] The motor body 3511 of the drive motor 351 may be positioned midway between the left end and the right end of the pop-up handle 31, relative to the pop-up handle 31, so that rotational driving force can be generated simultaneously on both the left and right ends of the pop-up handle 31.

[0228] Furthermore, the motor body 3511 may output rotational driving force in both directions so that it can generate rotational driving force all at once.

[0229] More specifically, as shown in the figure, the drive motor 351 may include a first output shaft 3512a that extends horizontally toward a second handle body 3112 which constitutes the left end of the pop-up handle 31.

[0230] Based on the illustrated embodiment, the first output shaft 3512a may extend horizontally through the left side of the motor body 3511 toward the second handle body 3112.

[0231] Furthermore, the drive motor 351 may include a second output shaft 3512b that extends horizontally toward the third handle body 3113, which constitutes the right end of the pop-up handle 31.

[0232] Based on the illustrated embodiment, the second output shaft 3512b may extend horizontally through the right side of the motor body 3511 toward the third handle body 3113.

[0233] In this case, as shown in Figure 12, a first gap (W1) may 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, with reference to the left-right direction (Le-Ri direction).

[0234] Furthermore, as shown in Figure 12, a second gap (W2) may 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, with reference to the left-right direction (Le-Ri direction).

[0235] In this case, the first interval (W1) and the second interval (W2) may be formed identically to each other.

[0236] As will be described later, the rotational driving force of the first output shaft 3512a may be transmitted to the first lead screw 352a via the first coupler 355a.

[0237] Furthermore, the rotational driving force of the second output shaft 3512b may be transmitted to the second lead screw 352b via the second coupler 355a.

[0238] In this way, by setting the first interval (W1) and the second interval (W2) to be the same, it is possible to use a first lead screw 352a and a second lead screw 352b having the same length and shape.

[0239] In other words, the first lead screw 352a and the second lead screw 352b may be arranged to be interchangeable with each other. This allows for the commonality of parts.

[0240] As described above, the pop-up handle 31 of the dishwasher 1 according to one embodiment of the present invention may be configured to repeatedly move forward from the retracted position (Pa) to the extended position (Pd), and backward from the extended position (Pd) to the retracted position (Pa), and to reciprocate between the extended position (Pd) and the retracted position (Pa).

[0241] To easily realize such repeated reciprocating movements, the drive motor 351 constituting the handle drive unit 35 may be configured to generate rotational driving force in both directions.

[0242] Therefore, the drive motor 351 applied to the handle drive unit 35 of the dishwasher 1 according to one embodiment of the present invention can be any type of motor that can generate rotational driving force in both directions.

[0243] In the following, among the rotational driving forces in both directions, the drive in the direction in which the output shaft 3512 of the drive motor 351 rotates in order to move the pop-up handle 31 forward toward the deployed position (Pd) will be referred to as the positive rotational drive or positive rotational driving force.

[0244] Furthermore, of the rotational driving forces in both directions, the drive in the direction in which the output shaft 3512 of the drive motor 351 rotates to move the pop-up handle 31 backward toward the retracted position (Pa) will be referred to as the reverse rotational drive or reverse rotational driving force.

[0245] On the other hand, as shown in Figures 6 and 7, the motor body 3511 of the drive motor 351 may be fixed inside the handle frame 30d.

[0246] More specifically, the motor body 3511 of the drive motor 351 may be housed inside a hollow, box-shaped motor bracket 3511a and forcibly coupled to the rear surface of the front wall 30d11 of the frame body 30d1 of the handle frame 30d by fastening means such as screws.

[0247] To prevent and avoid interference between the first output shaft 3512a and the second output shaft 3512b, which extend along the left-right direction (Le-Ri direction), the upper and lower surfaces of the motor bracket 3511a may be integrally provided with a plurality of fastening tabs having screw holes.

[0248] As will be described later, a number of first screw bosses 30d5 may be integrally formed protruding from the rear surface of the front wall 30d11 of the frame body 30d1, corresponding to the positions of multiple fastening tabs.

[0249] On the other hand, the handle drive unit 35 may further include a pair of lead screws 352a and 352b.

[0250] The pair of lead screws 352a and 352b are responsible for transmitting the rotational driving force generated from the drive motor 351 to the motion conversion units 353a, 354a, 353b, and 354b, which will be described later.

[0251] More specifically, the pair of lead screws 352a, 352b may include a first lead screw 352a that is connected to the first output shaft 3512a of the drive motor 351 and rotates when rotational driving force is transmitted from the first output shaft 3512a.

[0252] As an example, the first lead screw 352a may have a cylindrical shape extending along the left-right direction, similar to the first output shaft 3512a.

[0253] Furthermore, the first lead screw 352a may be connected to the first output shaft 3512a in a state where it is capable of rotation but is unable to move along the front-rear direction (FR direction) or the left-right direction (Le-Ri direction).

[0254] Therefore, the right end of the first lead screw 352a may be connected to the first output shaft 3512a so as to rotate integrally with the first output shaft 3512a.

[0255] Furthermore, the left end of the first lead screw 352a may be rotatably supported by the bushing portion 3722 of the first bracket 372 of the blind module 37, which will be described later.

[0256] On the other hand, a male thread having a predetermined vertical width may be formed on the outer circumferential surface of the left end of the first lead screw 352a.

[0257] As described later, the first nut 353a, which constitutes the first motion conversion section 353a, 354a, may be screw-connected to the male screw thread.

[0258] As described later, the rotation of the first lead screw 352a in the forward or reverse direction causes the first nut 353a to move linearly along the left-right direction (Le-Ri direction), and the rotational driving force of the first lead screw 352a may be converted into a linear driving force in the left-right direction (Le-Ri direction) by the first nut 353a.

[0259] To ensure a predetermined margin of error for the linear movement range of the first nut 353a, the vertical width of the male threads formed on the first lead screw 352a may be formed to be slightly wider than the horizontal linear movement range of the first nut 353a.

[0260] Furthermore, the pair of lead screws may include a second lead screw 352a that is connected to the second output shaft 3512b of the drive motor 351 and rotates when rotational driving force is transmitted from the second output shaft 3512b.

[0261] As an example, the second lead screw 352b may have a cylindrical shape extending along the left-right direction, similar to the second output shaft 3512b.

[0262] Furthermore, the second lead screw 352b may be connected to the second output shaft 3512b in a state where it is capable of rotation but is unable to move along the front-rear direction (FR direction) or the left-right direction (Le-Ri direction).

[0263] Therefore, the left end of the second lead screw 352b may be connected to the second output shaft 3512b so as to rotate integrally with the second output shaft 3512b.

[0264] Furthermore, the right end of the second lead screw 352b may be rotatably supported by the bushing portion 3732 of the second bracket 373 of the blind module 37, which will be described later.

[0265] On the other hand, a male thread having a predetermined vertical width may be formed on the outer circumferential surface of the right end of the second lead screw 352b.

[0266] As described later, the second nut 353b, which constitutes the second motion conversion section 353b, 354b, may be screw-connected to the male screw thread.

[0267] As described later, the rotation of the second lead screw 352b in the forward or reverse direction causes the second nut 353b to move linearly along the left-right direction (Le-Ri direction), and the rotational driving force of the second lead screw 352b may be converted by the second nut 353b into a linear driving force in the left-right direction (Le-Ri direction).

[0268] To ensure a predetermined margin of error for the linear movement range of the second nut 353b, the vertical width of the male threads formed on the second lead screw 352b may be formed to be slightly wider than the horizontal linear movement range of the second nut 353b.

[0269] As mentioned above, the first lead screw 352a and the second lead screw 352b may be configured to have the same length and shape as each other.

[0270] Therefore, the first lead screw 352a and the second lead screw 352b may be arranged to be interchangeable with each other. This allows for the commonality of parts.

[0271] On the other hand, the handle drive unit 35 may further include a pair of couplers 355a and 355b.

[0272] More specifically, the pair of couplers 355a, 355b may include a first coupler 355a that connects the first output shaft 3512a and the first lead screw 352a of the drive motor 351 so that they rotate together as a single unit.

[0273] Furthermore, the pair of couplers 355a, 355b may include a second coupler 355a that connects the second output shaft 3512b and the second lead screw 352b of the drive motor 351 so that they rotate together as a single unit.

[0274] Even if the first output shaft 3512a and the first lead screw 352a of the drive motor 351 are not aligned on the same axis of rotation, the rotational driving force of the first output shaft 3512a can be effectively transmitted to the first lead screw 352a via the first coupler 355a.

[0275] Furthermore, even if the second output shaft 3512b and the second lead screw 352b of the drive motor 351 are not aligned on the same axis of rotation, the rotational driving force of the second output shaft 3512b can be effectively transmitted to the second lead screw 352b via the second coupler 355a.

[0276] Similar to the first lead screw 352a and the second lead screw 352b, the first coupler 355a and the second coupler 355a may be arranged to be interchangeable with each other.

[0277] On the other hand, the handle drive unit 35 may further include a pair of motion conversion units.

[0278] First, as shown in FIG. 8, the pair of motion conversion units may include first motion conversion units 353a and 354a that convert the rotational driving force transmitted from the first lead screw 352a into a linear driving force in the front-rear direction (F-R direction).

[0279] The linear driving force in the front-rear direction (F-R direction) converted through the first motion conversion units 353a and 354a may be transmitted to the second handle body 3112 that forms the left end portion of the popup handle 31.

[0280] More specifically, the first motion conversion units 353a and 354a may include a first nut 353a that is screwed to the male screw portion of the first lead screw 352a described above.

[0281] As an example, the first nut 353a may have an outer shape having an inverted L shape when viewed from above.

[0282] The first lead screw 352a may be screwed to the first part that forms the inverted L shape and extends along the front-rear direction.

[0283] A female screw portion to which the male screw thread of the first lead screw 352a is screwed may be formed to penetrate along the left-right direction in the first part.

[0284] One end portion of a first link portion 354a described later may be connected to the second part of the first nut 353a so as to be relatively rotatable, the second part being formed to extend from the rear end edge of the first part in the leftward direction to form the inverted L shape.

[0285] One end portion of the first link portion 354a may be connected to the second part of the first nut 353a so as to be relatively rotatable via a first moving pin (Pm1).

[0286] Pin insertion holes may be formed to penetrate along the up-down direction (U-D direction) in the second part of the first nut 353a so that the first moving pin (Pm1) is inserted and coupled along the up-down direction (U-D direction).

[0287] On the other hand, the first motion conversion units 353a and 354a may further include a first link unit 354a that converts the linear driving force in the left-right direction (Le-Ri direction) transmitted from the first nut 353a into a linear driving force in the front-rear direction (FR direction).

[0288] As an example, the first link section 354a may consist of a pair of links comprising a first drive link 354a1 and a first driven link 354a2.

[0289] As shown in the figure, the first drive link 354a1 may have one end divided into a fork shape and the other end having a simple plate shape.

[0290] One end of the fork-shaped first drive link 354a1 may be connected to the second part of the first nut 353a via the first movable pin (Pm1) so as to be rotatable relative to it, as described above.

[0291] On the other hand, the other end of the first drive link 354a1, which has a simple plate shape, may be connected to the third handle body 3113 via a second moving pin (Pm2) so as to be rotatable relative to it.

[0292] In this case, the upper and lower ends of the second moving pin (Pm2) may be inserted into the pin guide slit 30h11 formed through the first guide bracket 30h1, which will be described later.

[0293] As will be described later, the pin guide slit 30h11 may be an elongated hole extending along the front-rear direction (FR direction) so as to be able to guide the direction of movement of the pop-up handle 31.

[0294] Therefore, the other end of the first drive link 354a1 and the second handle body 3112 may be guided in a direction of movement by the second moving pin (Pm2) and the pin guide slit 30h11 so as to move linearly along the front-rear direction (FR direction).

[0295] As shown in the figure, the first drive link 354a1 may have one end divided into a fork shape and the other end having a simple plate shape.

[0296] On the other hand, the first driven link 354a2 plays the role of forming the overall rotation center of the first drive link 354a1 between one end and the other end as the first nut 353a moves linearly along the left-right direction (Le-Ri direction), and also plays the role of varying the overall rotation center of the first drive link 354a1.

[0297] Therefore, one end of the first driven link 354a2 may be connected to the third movable pin (Pm3) at an intermediate position between the one end and the other end of the first driven link 354a2 so as to be rotatable relative to it.

[0298] On the other hand, so that the overall rotation center of the first drive link 354a1 can be varied, the other end of the first driven link 354a2 may be connected to the pin hole 30h13 of the first guide bracket 30h1 via a fixing pin (Pf) so as to be rotatable relative to it.

[0299] Unlike the other end of the first drive link 354a1, the other end of the first driven link 354a2 is connected to a pin hole 30h13, which is a simple circular hole, via a fixing pin (Pf). Therefore, the other end of the first driven link 354a2 may be connected inside the first guide bracket 30h1 in a state where it can rotate but cannot move along the front-rear direction (FR direction) or the left-right direction (Le-Ri direction).

[0300] To increase the connection strength to the first guide bracket 30h1, the other end of the first driven link 354a2 may be provided in a hollow cylindrical shape.

[0301] On the other hand, as shown in the figure, the third moving pin (Pm3) may be positioned even closer to the first moving pin (Pm1) than the second moving pin (Pm2).

[0302] Thus, the rotation amount at the other end of the first drive link 354a1 may be formed to be larger than the rotation amount at one end of the first drive link 354a1, with the third moving pin (Pm3) which is the overall rotation center of the first drive link 354a1 as the center.

[0303] Therefore, even if the linear movement amount of the first nut 353a in the left-right direction (Le-Ri direction) is not increased, the stroke (Ls) for the first drive link 354a1 to push or pull the second handle body 312 of the popup handle 31 can be effectively ensured.

[0304] On the other hand, the pair of motion conversion parts may include second motion conversion parts 353b and 354b that convert the rotational driving force transmitted from the second lead screw 352b into a linear driving force in the front-rear direction (F-R direction).

[0305] As described above, the first motion conversion parts 353a and 354a and the second motion conversion parts 353b and 354b are configured to be driven via a single drive motor 351.

[0306] Therefore, the first motion conversion parts 353a and 354a and the second motion conversion parts 353b and 354b may be arranged at positions symmetric to each other with respect to a vertical plane that evenly divides the popup handle 31 in the horizontal direction, so that the rotational driving force is evenly transmitted to the first motion conversion parts 353a and 354a and the second motion conversion parts 353b and 354b.

[0307] Also, for the same reason, the first motion conversion parts 353a and 354a and the second motion conversion parts 353b and 354b may have shapes symmetric to each other with respect to a vertical plane that evenly divides the popup handle 31 in the horizontal direction. [[ID=2I]]

[0308] Therefore, the second nut 353b that constitutes the second motion conversion parts 353b and 354b may be arranged at a position symmetric to the shape symmetric to the first nut 353a of the first motion conversion parts 353a and 354a.

[0309] Furthermore, the detailed configuration of the second link section 354b, which constitutes the second motion conversion sections 353b and 354b and includes the second drive link 354b1 and the second driven link 354b2, may be arranged in a position symmetrical to the first link section 354a of the first motion conversion sections 353a and 354a.

[0310] Since the second motion conversion units 353b and 354b are positioned symmetrically to the first motion conversion units 353a and 354a, any redundant explanations regarding them will be omitted below.

[0311] On the other hand, the present invention is configured to drive the pop-up handle 31 via a single drive motor 351, through first motion conversion units 353a, 354a and second motion conversion units 353b, 354b which are arranged symmetrically in a symmetrical shape.

[0312] Therefore, due to machining tolerances and assembly tolerances of the first motion conversion units 353a, 354a, the second motion conversion units 353b, 354b, and the pop-up handle 31, the stroke (Ls) of the pop-up handle 31, which moves from the retracted position (Pa) to the deployed position (Pd), may be formed to differ from that of the second handle body 3112 and the third handle body 3113, respectively.

[0313] 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.

[0314] If the positional deviation in the front-rear direction (FR direction) between the second handle body 3112 and the third handle body 3113 exceeds a predetermined level, the load on the drive motor 351 may increase rapidly.

[0315] Furthermore, the load on the first motion conversion units 353a, 354a and the second motion conversion units 353b, 354b, which convert and transmit driving force to the second handle body 3112 and the third handle body 3113 respectively, may also increase rapidly, potentially causing damage to the first motion conversion units 353a, 354a and the second motion conversion units 353b, 354b.

[0316] Furthermore, this could also cause damage to the second handle body 3112 and the third handle body 3113 that make up the pop-up handle 31.

[0317] Thus, as a means to minimize 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 drive unit 35 of the pop-up handle 31 of the dishwasher 1 according to one embodiment of the present invention may include positional deviation adjustment units 356a and 356b.

[0318] More specifically, as shown in Figure 7, the position deviation adjustment units 356a and 356b may include a first deviation adjustment unit 356a that adjusts the position of the second handle body 3112 in the front-rear direction (FR direction), and a second deviation adjustment unit 356b that adjusts the position of the third handle body 3113 in the front-rear direction (FR direction).

[0319] The first deviation adjustment unit 356a and the second deviation adjustment unit 356b may be configured to apply a force that pushes the second handle body 3112 forward or the third handle body 3113 backward, respectively, when a deviation occurs between the front-rear (FR) position of the second handle body 3112 and the front-rear (FR) position of the third handle body 3113.

[0320] The first deviation adjustment unit 356a and the second deviation adjustment unit 356b may be arranged symmetrically with respect to a vertical plane that evenly divides the pop-up handle 31 along the horizontal direction, so that a force can be applied to push out the second handle body 3112 and the third handle body 3113 in a direction that minimizes the deviation while a positional deviation occurs.

[0321] For similar reasons, the first deviation adjustment section 356a and the second deviation adjustment section 356b may have shapes that are symmetrical with respect to a vertical plane that evenly divides the pop-up handle 31 along the horizontal direction.

[0322] The detailed configuration of the position deviation adjustment units 356a and 356b, including the first deviation adjustment unit 356a and the second deviation adjustment unit 356b, will be described later with reference to Figures 15 to 17.

[0323] On the other hand, a dishwasher 1 according to one embodiment of the present invention may include a blind module 37 that shields 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).

[0324] As described above, when the pop-up handle 31 is moved to the deployed position (Pd), the opening 30e of the front panel 30a, which is formed to penetrate in the front-rear direction (FR direction) for the pop-up handle 31 to pass through, becomes at least partially open, except for the portion occupied by the second handle body 3112 and the third handle body 3113.

[0325] The blind module 37 plays the role of shielding the opening 30e and the handle opening 30d2 of the handle frame 30d (described later) so that foreign objects from the outside do not enter through the opening 30e, which is thus opened at least partially toward the front, or so that the inside of the door 30 cannot be observed.

[0326] For the time being, as shown in Figures 8 and 9, the blind module 37 may, as an example, include a blind panel 371 that is arranged to be movable along the front-rear direction (FR direction) in conjunction with the reciprocating movement of the pop-up handle 31.

[0327] More specifically, the blind panel 371 may include a plate-shaped panel body 3711 that shields the opening 30e and the handle entrance 30d2.

[0328] The panel body 3711 may have a rectangular shape, corresponding to the shape of the opening 30e and the handle entrance 30d2.

[0329] The width of the panel body 3711 in the left-right direction may be set to be the same as, or slightly smaller than, the width in the left-right direction between the second handle body 3112 and the third handle body 3113, so that the opening 30e and the handle entrance 30d2, which are partially opened after being moved to the deployed position (Pd), can be shielded.

[0330] When the opening 30e and the handle opening 30d2 are shielded by the panel body 3711, the front end surface 3711a of the panel body 3711 is exposed to the outside through the opening 30e and the handle opening 30d2.

[0331] To minimize any sense of incongruity with the front panel 30a, the front end surface 3711a of the panel body 3711 may be surface-treated to have the same texture and hue as the front surface of the front panel 30a.

[0332] Furthermore, when the opening 30e and the handle entrance / exit 30d2 are shielded by the panel body 3711, the front end surface 3711a of the panel body 3711 may form a continuous surface with the front surface of the front panel 30a, or it may protrude slightly from the front panel 30a.

[0333] This prevents foreign matter such as dust from accumulating in the opening 30e and the handle entrance / exit 30d2 by either forming the same surface as the front surface of the front panel 30a or by protruding slightly from the front panel 30a.

[0334] The blind panel 371 may further include flange portions 3712 formed on the upper end surface 3711b and the lower end surface 3711c of the panel body 3711.

[0335] When it reaches the position where it will be shielded, the front end surface 3711a of the panel body 3711 must either form a continuous surface with the front surface of the front panel 30a, or stop with a small protrusion from the front panel 30a.

[0336] The flange portion 3712 thus acts as a stopper, preventing the panel body 3711 from moving further forward after it has reached its foremost position.

[0337] Taking into consideration the shape of the panel body 3711, the flange portion 3712 may extend linearly along the rear end edge of the upper end surface 3711b of the panel body 3711.

[0338] Furthermore, the flange portion 3712 may extend linearly along the rear end edge of the lower end surface 3711c of the panel body 3711.

[0339] Furthermore, the height at which the flange portion 3712 protrudes from the upper end surface 3711b of the panel body 3711, and the height at which it protrudes from the lower end surface 3711c of the panel body 3711, may be maintained substantially constant as it progresses from the left end to the right end of the panel body 3711.

[0340] As described later, when the panel body 3711 moves to its furthest forward position, the flange portion 3712 may come into contact with and collide with the rear end edge of the inlet / outlet rib 30d3 of the handle frame 30d, and the panel body 3711 may stop at its furthest forward position.

[0341] On the other hand, as shown in the illustrated embodiment, the flange portion 3712 may be provided with a number of slits 3712a.

[0342] The numerous slits 3712a may extend along the vertical direction (UD direction) from the upper edge to the lower edge of the flange portion 3712.

[0343] Furthermore, the widths of the numerous slits 3712a in the left-right direction may be set to be approximately the same for each of them.

[0344] Furthermore, numerous reinforcing ribs 30d4, which will be formed inside the handle frame 30d later, may be inserted into the numerous slits 3712a.

[0345] As will be described later, each reinforcing rib 30d4 maintains a nearly constant thickness as it progresses along the front-rear direction (FR direction).

[0346] Furthermore, the width of the numerous slits 3712a in the left-right direction may be the same as, or even greater than, the thickness of the reinforcing rib 30d4 of the handle frame 30d.

[0347] In this way, by positioning the blind panel 371 such that the reinforcing ribs 30d4 of the handle frame 30d are inserted into each slit 3712a, the slits 3712a of the flange portion 3712 and the reinforcing ribs 30d4 of the handle frame 30d can act as guide means to guide the reciprocating movement of the blind panel 371.

[0348] On the other hand, the blind panel 371 may be connected to the first bracket 372 and the second bracket 373, which will be described later, so that the distance between them in the front-rear direction (FR direction) is variable.

[0349] Thus, the rear surface of the panel body 3711 may be provided with at least one first projection 3711d that protrudes toward the first bracket 372 and the second bracket 373, so that it can be connected to the first bracket 372 and the second bracket 373 while a variable spacing is formed.

[0350] The illustrated embodiment shows a configuration in which the first bracket 372 is connected via a total of four first protrusions 3711d, and the second bracket 373 is connected via a total of four first protrusions 3711d.

[0351] However, this is merely an example, and the number of first projections 3711d may be adjusted by the width of the blind panel 371 in the left-right direction or the up-down direction.

[0352] The first projection 3711d may be connected in a telescopic manner so that the distance in the front-rear direction (FR direction) can be variably adjusted.

[0353] To enable connection in a telescopic manner, the first projection 3711d may be a solid rib, and the second projection 3721d into which the first projection 3711d is joined and inserted may be a hollow rib.

[0354] As will be described later, the second projection 3721d may be formed to protrude toward the panel body 3711 from the front surface 3721a of the first bracket 372 and the front surface 3731a of the second bracket 373.

[0355] Furthermore, the blind module 37 may include brackets 372, 373 that support the blind panel 371 in a relative movable manner.

[0356] In this case, in order to prevent interference with the shape of the blind panel 371, where the left-right direction (Le-Ri direction) is the longitudinal direction, and with the drive motor 351 located behind the blind panel 371, the brackets 372 and 373 may, as an example, be provided as a first bracket 372 and a second bracket 373.

[0357] The first bracket 372 supports the left portion of the blind panel 371 so that it is relatively movable, and its role is to prevent the blind panel 371 from detaching backward.

[0358] The front surface 3721a of the bracket body 3721 of the first bracket 372 may be provided with at least one second projection 3721d that protrudes toward the left portion of the blind panel 371, so that the left portion of the blind panel 371 can be supported in a relative movable manner, that is, so that the distance in the front-rear direction (FR direction) can be variably connected.

[0359] As in the embodiment, if a total of four first protrusions 3711d are provided on the rear surface of the blind panel 371, then correspondingly, a total of four second protrusions 3721d may be provided on the front surface 3721a of the bracket body 3721 of the first bracket 372.

[0360] As mentioned above, the second projections 3721d of each first bracket 372 may be hollow ribs so that they can be connected to the first projection 3711d of the blind panel 371 in a telescopic manner.

[0361] The hollow portion formed inside the second projection 3721d of the first bracket 372 may be formed continuously from the front end of the second projection 3721d to the rear surface of the bracket body 3721 of the first bracket 372.

[0362] The first bracket 372 may be fastened to the handle frame 30d, which will be described later.

[0363] For fastening to the handle frame 30d, the first bracket 372 may be provided with a plurality of fastening bosses 3721c, the screw holes of which are formed to penetrate along the front-rear direction (FR direction).

[0364] As an example, the multiple fastening bosses 3721c of the first bracket 372 may be provided in pairs close to the upper surface of the bracket body 3721 of the first bracket 372, or in pairs close to the lower surface of the bracket body 3721 of the first bracket 372.

[0365] Corresponding to the multiple fastening bosses 3721c of the first bracket 372, the handle frame 30d may be integrally provided with two pairs of second screw bosses 30d6 arranged via a handle opening 30d2.

[0366] On the other hand, as mentioned above, the first bracket 372 can also serve the role of supporting the first lead screw 352a so that it can rotate.

[0367] Therefore, a bushing portion 3722 may be integrally provided on the left end surface 3721b of the bracket body 3721 of the first bracket 372.

[0368] The bushing portion 3722 may be provided with a circular hole formed through it in the left-right direction.

[0369] The left end of the first lead screw 352a may be inserted into the circular hole of the bushing portion 3722 of the first bracket 372 and supported by the bushing portion 3722 so as to be able to rotate.

[0370] On the other hand, the second bracket 373, like the first bracket 372, supports the right-side portion of the blind panel 371 so that it can move relative to it, and plays a role in preventing the blind panel 371 from detaching backward.

[0371] Similar to the first bracket 372, the front surface 3731a of the bracket body 3731 of the second bracket 373 may be provided with at least one second projection 3731d that protrudes toward the left portion of the blind panel 371, so that the right portion of the blind panel 371 can be supported in a relative movable manner, that is, so that the distance in the front-rear direction (FR direction) can be variably connected.

[0372] As in the embodiment, if a total of four first protrusions 3711d are provided on the rear surface of the blind panel 371, then correspondingly, a total of four second protrusions 3731d may be provided on the front surface 3731a of the bracket body 3731 of the second bracket 373.

[0373] As mentioned above, the second projections 3731d of each second bracket 373 may be hollow ribs so that they can be connected to the first projection 3711d of the blind panel 371 in a telescopic manner.

[0374] The hollow portion formed inside the second projection 3731d of the second bracket 373 may be formed continuously from the front end of the second projection 3731d of the second bracket 373 to the rear surface of the bracket body 3731 of the second bracket 373.

[0375] Similar to the first bracket 372, the second bracket 373 may be fastened to the handle frame 30d, which will be described later.

[0376] For fastening to the handle frame 30d, the second bracket 373 may be provided with a plurality of fastening bosses 3731c, each having screw holes formed through it in the front-rear direction.

[0377] For example, the multiple fastening bosses 3731c of the second bracket 373 may be provided in pairs close to the upper surface of the bracket body 3731 of the second bracket 373, and in pairs close to the lower surface of the bracket body 3731 of the second bracket 373.

[0378] Corresponding to the multiple fastening bosses 3731c of the second bracket 373, the handle frame 30d may be integrally provided with two pairs of second screw bosses 30d6 arranged via the handle opening 30d2.

[0379] Furthermore, the second bracket 373 can also serve the role of supporting the second lead screw 352b so that it can rotate.

[0380] Therefore, a bushing portion 3732 may be integrally provided on the right end surface 3731b of the bracket body 3731 of the second bracket 373.

[0381] The bushing portion 3732 of the second bracket 373 may be provided with a circular hole formed through it in the left-right direction.

[0382] The right end of the second lead screw 352b may be inserted into the circular hole of the bushing portion 3732 of the second bracket 373 and supported by the bushing portion 3732 so as to be able to rotate.

[0383] On the other hand, the blind module 37 may further include a plurality of compression springs 374, each positioned between the first bracket 372 and the blind panel 371, and between the second bracket 373 and the blind panel 371.

[0384] Multiple compression springs 374 play a role in pushing the blind panel 371 forward so that it moves in conjunction with the reciprocating movement of the pop-up handle 31.

[0385] If the blind panel 371 is supported so as to be relatively movable via a first bracket 372 and a second bracket 373, at least one compression spring 374 may be provided between the first bracket 372 and the left portion of the blind panel 371, and between the second bracket 373 and the right portion of the blind panel 371.

[0386] The illustrated embodiment shows, as an example, a configuration in which the compression spring 374 is provided as a coil spring that is compressed and positioned between the first bracket 372 and the blind panel 371, and between the second bracket 373 and the blind panel 371.

[0387] Although the present invention is not limited thereto, the description will be based on an embodiment in which a coil spring is provided as the compression spring 374.

[0388] The compression spring 374 may be positioned between the first bracket 372 and the left portion of the blind panel 371, such that the first projection 3711d of the blind panel 371 and the second projection 3721d of the first bracket 372 pass through it.

[0389] At this time, the front end of the compression spring 374 contacts the rear surface of the left portion of the blind panel 371.

[0390] Furthermore, the rear end of the compression spring 374 contacts the front surface 3721a of the first bracket 372.

[0391] Thus, when the compression spring 374 is compressed, it may contact the rear surface of the left portion of the blind panel 371 and the front surface 3721a of the first bracket 372, thereby creating a state in which the restoring force of the compression spring 374 constantly pushes the left portion of the blind panel 371 forward.

[0392] Alternatively, the compression spring 374 may be positioned between the second bracket 373 and the right-side portion of the blind panel 371, such that the first projection 3711d of the blind panel 371 and the second projection 3731d of the second bracket 373 pass through its interior.

[0393] At this time, the front end of the compression spring 374 contacts the rear surface of the right-side portion of the blind panel 371.

[0394] Furthermore, the rear end of the compression spring 374 contacts the front surface 3731a of the second bracket 373.

[0395] In this way, when the compression spring 374 is compressed, it may contact the rear surface of the right portion of the blind panel 371 and the front surface 3731a of the second bracket 373, thereby creating a state in which the restoring force of the compression spring 374 constantly pushes the left portion of the blind panel 371 forward.

[0396] The illustrated embodiment shows a configuration in which one compression spring 374 is positioned between the first bracket 372 and the left portion of the blind panel 371, and another compression spring 374 is positioned between the second bracket 373 and the right portion of the blind panel 371.

[0397] The number of compression springs 374 provided may be increased depending on the size and weight of the blind panel 371.

[0398] However, the number of compression springs 374 positioned between the first bracket 372 and the left portion of the blind panel 371, and the number of compression springs 374 positioned between the second bracket 373 and the right portion of the blind panel 371, may be set to be the same so that the same restoring force acts on both sides of the blind panel 371.

[0399] For similar reasons, the spring constant of the compression spring 374 positioned between the first bracket 372 and the left portion of the blind panel 371 and the spring constant of the compression spring 374 positioned between the second bracket 373 and the right portion of the blind panel 371 may be set to be the same as each other.

[0400] The specific process by which the blind panel 371 moves in conjunction with the movement of the pop-up handle 31 will be described later with reference to Figures 12 to 14.

[0401] On the other hand, a dishwasher 1 according to one embodiment of the present invention may include a handle drive unit 35 and a handle frame 30d that houses a pop-up handle 31.

[0402] More specifically, the handle frame 30d may include a frame body 30d1 that houses the pop-up handle 31 and the handle drive unit 35.

[0403] As shown in Figures 6 and 7, the frame body 30d1 may have a hollow box shape so as to be able to house and support the pop-up handle 31 and the handle drive unit 35 entirely inside.

[0404] In this case, the rear surface of the frame body 30d1 may be left completely open so that the pop-up handle 31 and the handle drive unit 35 can be assembled via the rear.

[0405] In this case, in order to prevent water leakage from entering, the upper end wall 30d12 that constitutes the upper surface of the frame body 30d1, the lower end wall 30d13 that constitutes the lower surface, the left side wall 30d14 that constitutes the left side surface, and the right side wall 30d15 that constitutes the right side surface may be formed in a substantially closed state.

[0406] On the other hand, a handle opening 30d2 may be formed through the front wall 30d11 of the frame body 30d1, having a cross-sectional area and shape corresponding to the outer shape of the pop-up handle 31, so that the pop-up handle 31 can enter and exit. In this way, the front wall 30d11 of the frame body 30d1 may be partially open.

[0407] The handle entrance / exit 30d2 may be positioned directly behind the opening 30e of the front panel 30a, and may have substantially the same shape as the opening 30e of the front panel 30a. However, as will be described later, the cross-sectional area of ​​the handle entrance / exit 30d2 may be formed to be slightly larger than the cross-sectional area of ​​the opening 30e so that the opening flange 30e1 formed in the opening 30e of the front panel 30a can pass through the handle entrance / exit 30d2.

[0408] To improve space utilization, a control panel holder 321, which houses the aforementioned control panel 32, may be connected to the upper end wall 30d12 of the frame body 30d1 in a surface contact manner.

[0409] For similar reasons, the left side wall 30d14 of the frame body 30d1 may be formed as close as possible to the left side of the front panel 30a of the door 30, and the right side wall 30d15 of the frame body 30d1 may be formed as close as possible to the right side of the front panel 30a of the door 30.

[0410] Furthermore, the front wall 30d11 of the frame body 30d1 may be positioned in close contact with the rear surface of the front panel 30a of the door 30.

[0411] Therefore, the overall rigidity of the front panel 30a may be reinforced.

[0412] In particular, the rigidity of the front panel 30a in a position where the rigidity may be significantly reduced due to the formation of the opening 30e may be reinforced by the frame body 30d1.

[0413] On the other hand, a circuit board frame 30f that houses and supports a drive unit control board 357 for controlling the handle drive unit 35 may be arranged at the lower part of the handle frame 30d.

[0414] As mentioned above, the upper end wall 30d12 of the frame body 30d1 may be connected to a control panel 32 for controlling the operation of the dishwasher 1, and a control panel holder 321 for housing a control panel circuit board (not shown).

[0415] In other words, as shown in the illustrated embodiment, a drive unit control board 357 may be placed on the board frame 30f to control the handle drive unit 35, separately from the control panel 32 and the control panel board (not shown).

[0416] However, the illustrated embodiment may differ in that it is configured to integrate a single control board that can control both the operation of the dishwasher 1 and the operation of the pop-up handle 31. This has the effect of simplifying the internal structure of the door 30.

[0417] Thus, whether the control panel board and the drive unit control board 357 are provided separately or integrated together, they can both be electrically connected to a main controller (not shown) located in the main body of the dishwasher 1. Therefore, the main controller can control the operation of various detailed components that make up the dishwasher 1, including the pop-up handle 31.

[0418] The substrate frame 30f may be formed separately and coupled to the handle frame 30d, or it may be formed integrally with the handle frame 30d.

[0419] Figure 6 shows, as an example, that the substrate frame 30f is integrally connected to the handle frame 30d and formed as a single unit.

[0420] In this way, when the substrate frame 30f is formed integrally with the handle frame 30d, separate fastening means for fixing the substrate frame 30f to the front panel 30a of the door 30 can be omitted.

[0421] The handle frame 30d and the base plate frame 30f may be fastened directly to the front panel 30a of the door 30, or indirectly to the front panel 30a of the door 30.

[0422] A fixing bracket 30g may be provided as a means for indirectly fastening the handle frame 30d to the front panel 30a of the door 30.

[0423] As shown in Figures 6 and 7, the fixing bracket 30g may extend in a shape that at least partially surrounds the rear end edge of the frame body 30d1 of the handle frame 30d.

[0424] As shown in the figure, the fixed bracket 30g can be provided with a number of fastening holes through which fastening means such as screw bolts can pass.

[0425] Of the numerous fastening holes, some are responsible for fastening the fixing bracket 30g to the front panel 30a of the door 30, while the other fastening holes are responsible for fastening the fixing bracket 30g to the frame body 30d1 of the handle frame 30d.

[0426] As an example, screw bosses may be integrally formed on the left wall 30d14, the right wall 30d15, and the lower end wall 30d13 of the frame body 30d1, allowing screw bolts that pass through the fastening holes of the fixing bracket 30g to be fastened.

[0427] Thus, the handle frame 30d and the base frame 30f may be indirectly fastened to the front panel 30a of the door 30 via the fixing bracket 30g.

[0428] Means for directly fastening the handle frame 30d to the front panel 30a of the door 30 may be provided on the entrance / exit rib 30d3 of the frame body 30d1.

[0429] As shown in Figure 11, the opening 30e of the front panel 30a of the door 30 may be provided with an opening flange 30e1 that extends toward the rear.

[0430] The opening flange 30e1 may be formed by partially bending and plastically deforming the front panel 30a toward the rear.

[0431] The opening flange 30e1 may be formed integrally with the lower end edge and the upper end edge of the opening 30e.

[0432] The opening flange 30e1 formed at the lower end edge of the opening 30e may extend linearly along the lower end edge of the opening 30e.

[0433] Furthermore, the width of the opening flange 30e1 formed at the lower end edge of the opening 30e in the front-rear direction may be maintained substantially constant as it progresses along the lower end edge of the opening 30e.

[0434] The opening flange 30e1 formed on the upper edge of the opening 30e may extend linearly along the upper edge of the opening 30e.

[0435] Furthermore, the width of the opening flange 30e1 formed on the upper edge of the opening 30e in the front-rear direction may be kept substantially constant as it progresses along the upper edge of the opening 30e.

[0436] As shown in Figure 10, the opening flange 30e1 may extend into the interior of the frame body 30d1 by passing through the handle opening 30d2 of the frame body 30d1 of the handle frame 30d.

[0437] Similar to the opening flange 30e1 of the front panel 30a of the door 30, the handle entrance 30d2 of the handle frame 30d may be integrally provided with an entrance rib 30d3 that extends toward the interior of the frame body 30d1.

[0438] The entrance / exit rib 30d3 may be integrally formed with the lower end edge of the handle entrance / exit 30d2 and the upper end edge of the handle entrance / exit 30d2.

[0439] The entrance rib 30d3 formed on the lower end edge of the handle entrance 30d2 may extend linearly along the lower end edge of the handle entrance 30d2.

[0440] Furthermore, the width of the entrance rib 30d3 formed on the lower edge of the handle entrance 30d2 in the front-rear direction may be kept substantially constant as it progresses along the lower edge of the handle entrance 30d2.

[0441] The entrance rib 30d3 formed on the upper edge of the handle entrance 30d2 may extend linearly along the upper edge of the handle entrance 30d2.

[0442] Furthermore, the width of the entrance rib 30d3 formed on the upper edge of the handle entrance 30d2 in the front-rear direction may be kept substantially constant as it progresses along the upper edge of the handle entrance 30d2.

[0443] The front-to-rear width of the entrance rib 30d3 formed in the handle entrance 30d2 may be the same as, or even larger than, the front-to-rear width of the opening flange 30e1 formed in the opening 30e of the door 30.

[0444] In this case, as shown in the figure, a plurality of hook holes 30e2 may be formed in the opening flange 30e1 formed in the opening 30e of the door 30, extending through in the vertical direction.

[0445] Multiple hook portions 30d31, which are detachably connected to the individual hook holes 30e2, may be integrally formed on the entrance / exit rib 30d3 at positions corresponding to the individual hook holes 30e2.

[0446] The individual hook portion 30d31 may be formed integrally with the entrance / exit rib 30d3 by partially cutting open the entrance / exit rib 30d3.

[0447] In this way, by inserting and connecting the individual hook portions 30d31 into the corresponding individual hook holes 30e2, the multiple hook portions 30d31 and the multiple hook holes 30e2 function as means for directly fastening the handle frame 30d to the front panel 30a of the door 30.

[0448] Furthermore, the opening flange 30e1 of the door 30 and the entrance / exit rib 30d3 of the handle frame 30d are configured to be joined to each other in a surface contact state.

[0449] Through this surface contact connection, the opening flange 30e1 of the door 30 and the entrance / exit rib 30d3 of the handle frame 30d can mutually reinforce each other's rigidity.

[0450] On the other hand, as shown in Figure 10, the frame body 30d1 of the handle frame 30d may be integrally provided with a number of reinforcing ribs 30d4.

[0451] As mentioned above, the frame body 30d1 of the handle frame 30d is provided in the shape of a hollow box.

[0452] Furthermore, the rear surface of the frame body 30d1 is generally open, and a handle opening 30d2 corresponding to the outer shape of the pop-up handle 31 is formed through the front wall 30d11 of the frame body 30d1.

[0453] Therefore, in order to prevent deterioration of the rigidity of the frame body 30d1 due to the complete opening of the rear surface and the partial opening of the front wall 30d11, a number of reinforcing ribs 30d4 may be integrally provided.

[0454] Taking into consideration the complete opening of the rear surface and the partial opening of the front wall 30d11, the multiple reinforcing ribs 30d4 may be divided vertically and arranged with respect to the handle opening 30d2.

[0455] The reinforcing rib 30d4, positioned above the handle opening 30d2, may be integrally connected to the front wall 30d11 and the upper end wall 30d12 of the frame body 30d1.

[0456] The reinforcing rib 30d4, positioned below the handle opening 30d2, may be integrally connected to the front wall 30d11 and the lower end wall 30d13 of the frame body 30d1.

[0457] Furthermore, each reinforcing rib 30d4 may extend linearly along the front-to-back direction.

[0458] In this case, the length of each reinforcing rib 30d4 extending from the front wall 30d11 of the frame body 30d1 may be formed to differ from one another depending on the position in which it is positioned.

[0459] However, the thickness of each reinforcing rib 30d4 may be maintained at approximately constant levels as it progresses along the front-rear direction (FR direction).

[0460] As mentioned above, this is because each reinforcing rib 30d4 is configured to be inserted into a slit 3712a formed in the flange portion 3712 of the blind panel 371, so that the slit 3712a of the flange portion 3712 of the blind panel 371 and the reinforcing rib 30d4 of the handle frame 30d can act as guide means to guide the reciprocating movement of the blind panel 371.

[0461] On the other hand, as shown in the figure, a first screw boss 30d5 and a second screw boss 30d6 may be positioned between a pair of adjacent reinforcing ribs 30d4.

[0462] As mentioned above, the first screw boss 30d5 is intended to secure the motor bracket 3511a using a screw bolt.

[0463] Furthermore, as mentioned above, the second screw boss 30d6 is intended to fix the first bracket 372 and the second bracket 373 of the blind module 37 using screw bolts.

[0464] In this case, the first screw boss 30d5 and the adjacent reinforcing rib 30d4, and the second screw boss 30d6 and the adjacent reinforcing rib 30d4 may be integrally connected to each other via further ribs extending in the left-right direction. This further ensures the connection strength and rigidity between the first screw boss 30d5, the second screw boss 30d6, and the reinforcing rib 30d4.

[0465] On the other hand, the handle frame 30d can also serve the role of guiding the forward and backward movement of the pop-up handle 31.

[0466] In other words, as described above, the pop-up handle 31 may be configured to move horizontally along the forward direction (Dfw) or the reverse direction (Drw) by the forward or reverse driving force of the handle drive unit 35.

[0467] Means for realizing these horizontal movements may be provided in the pop-up handle 31 and the handle frame 30d in which the pop-up handle 31 is housed.

[0468] As a means of realizing horizontal movement, the pop-up handle 31 may include a pair of guide blocks 3114.

[0469] As mentioned above, either of the pair of guide blocks 3114 may be fixed to the left side of the second handle body 3112.

[0470] Furthermore, one of the pair of guide blocks 3114 may be fixed to the right side of the third handle body 3113.

[0471] In this case, the thickness of the pair of guide blocks 3114 in the left-right direction (Le-Ri direction) may be kept constant as they advance along the front-back direction (FR direction).

[0472] Furthermore, the vertical height (UD direction) of the pair of guide blocks 3114 may be kept constant as they move along the front-to-back direction (FR direction).

[0473] On the other hand, the handle frame 30d may include guide brackets 30h1 and 30h2 as a means of realizing horizontal movement.

[0474] The guide brackets 30h1 and 30h2 house the second handle body 3112 and the third handle body 3113 of the pop-up handle 31, and play a role in guiding the forward and backward horizontal movement of the second handle body 3112 and the third handle body 3113.

[0475] As an example, the guide brackets 30h1 and 30h2 may include a first guide bracket 30h1 that accommodates a second handle body 3112 and a second guide bracket 30h2 that accommodates a third handle body 3113.

[0476] The first guide bracket 30h1 and the second guide bracket 30h2 may be integrally provided with the frame body 30d1 of the handle frame 30d.

[0477] Furthermore, the first guide bracket 30h1 and the second guide bracket 30h2 may be formed separately from the frame body 30d1 and fastened to the frame body 30d1.

[0478] The illustrated embodiment shows a configuration in which the first guide bracket 30h1 and the second guide bracket 30h2 are formed separately and fastened to the frame body 30d1. The present invention is not limited thereto, but will be described based on the illustrated embodiment.

[0479] For the time being, as shown in Figure 11, the first guide bracket 30h1 may be formed in the shape of a hollow box so that the second handle body 3112 can be movably housed inside.

[0480] In this case, the front and rear surfaces of the first guide bracket 30h1 may be completely open so as to ensure horizontal movement of the second handle body 3112 in the front-rear direction (FR direction).

[0481] Furthermore, in order to prevent interference with the first drive link 354a1 and the first driven link 354a2 that constitute the handle drive unit 35, the right side of the first guide bracket 30h1 may be completely open.

[0482] In this case, a block guide groove 30h12 may be formed on the left side surface of the first guide bracket 30h1, which is convex toward the left direction (Le- direction).

[0483] A guide block 3114, which is attached to the second handle body 3112, may be inserted into the block guide groove 30h12.

[0484] The block guide groove 30h12 may have a cross-sectional shape that corresponds to the outer shape of the guide block 3114 that is attached to the second handle body 3112.

[0485] Furthermore, the block guide groove 30h12 may extend linearly along the front-rear direction (FR direction).

[0486] Therefore, with the guide block 3114 inserted into the block guide groove 30h12, the movement of the second handle body 3112 may guide the horizontal movement of the second handle body 3112 in the front-rear direction (FR direction).

[0487] Furthermore, as mentioned above, pin guide slits 30h11 extending linearly along the front-rear direction (FR direction) may be formed through the upper and lower surfaces of the first guide block 3114 along the vertical direction.

[0488] The upper end of the second movable pin (Pm2) is inserted into and connected to the pin guide slit 30h11 formed on the upper surface of the first guide block 3114.

[0489] Furthermore, the upper end of the second movable pin (Pm2) is inserted into and connected to the pin guide slit 30h11 formed on the lower surface of the first guide block 3114.

[0490] As mentioned above, the other end of the first drive link 354a1 is connected to the second handle body 3112 so as to be rotatable relative to it by the second moving pin (Pm2).

[0491] Since movement is guided with the second moving pin (Pm2) inserted into the pin guide slit 30h11, the other end of the second handle body 3112 and the first drive link 354a1 may be guided to move horizontally along the pin guide slit 30h11 in the front-rear direction (FR direction).

[0492] On the other hand, pin holes 30h13 may be formed through the upper and lower surfaces of the first guide bracket 30h1, respectively, along the vertical direction (UD direction), into which a fixing pin (Pf) is inserted and connected to connect the other end of the first driven link 354a2 to the first guide bracket 30h1 in a relative rotatable manner.

[0493] On the other hand, at least one sensor hole 30h14 may be formed through the lower surface of the first guide bracket 30h1 along the vertical direction (UD direction).

[0494] As shown in Figure 11, a dishwasher 1 according to one embodiment of the present invention may include a handle position sensor module (S_h) as a means for sensing the position of the pop-up handle 31.

[0495] The embodiment shows, as an example, a configuration 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, respectively.

[0496] In this way, when the handle position sensor module (S_h) is composed of a first switch (S_h1) and a second switch (S_h2), the first switch (S_h1) and the second switch (S_h2) may be arranged in a line along the front-rear direction (FR direction).

[0497] For example, the first switch (S_h1) may be placed at the front, and the second switch (S_h2) may be placed at the rear.

[0498] In this case, the levers of the first switch (S_h1) and the second switch (S_h2) may each extend inside through the sensor hole 30h14.

[0499] Therefore, as shown in the figure, when the second handle body 3112 is in the retracted position (Pa), the lever of the first switch (S_h1) and the lever of the second switch (S_h2) are pressed by the lower surface of the second handle body 3112.

[0500] 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) will output an ON signal.

[0501] Furthermore, when the second handle body 3112 begins to move from the retracted position (Pa) towards the extended position (Pd), the output signal of the second switch (S_h2) may be switched to an OFF signal.

[0502] Furthermore, once the second handle body 3112 has completed its movement to the deployed position (Pd), the output signal of the first switch (S_h1) may be switched to an OFF signal.

[0503] By sensing when the output signals of the first switch (S_h1) and the second switch (S_h2) switch from an ON signal to an OFF signal, the current position of the second handle body 3112 and whether or not the second handle body 3112 is moving can be effectively and easily detected.

[0504] On the other hand, the first switch (S_h1) and the second switch (S_h2) may be arranged between the lower end wall 30d13 of the frame body 30d1 and the lower surface of the first guide bracket 30h1, with the first switch (S_h1) and the second switch (S_h2) being fastened together and supported by the sensor holder (S_h3).

[0505] On the other hand, the second guide bracket 30h2 may be arranged symmetrically with respect to a vertical plane that evenly divides the pop-up handle 31 along the horizontal direction, so that the third handle body 3113 can be movably housed inside.

[0506] For similar reasons, the second guide bracket 30h2 may have a shape that is symmetrical with respect to the first guide bracket 30h1 with respect to a vertical plane that evenly divides the pop-up handle 31 along the horizontal direction.

[0507] Since the second guide bracket 30h2 is positioned symmetrically to the first guide bracket 30h1 in a shape that is symmetrical to it, any explanation regarding the redundant aspects of the second guide bracket 30h2 will be omitted below.

[0508] [Movement of the pop-up handle and operation of the blind module due to the operation of the handle drive mechanism] In the following, with reference to Figures 12 to 14, we will explain the process by which the pop-up handle 31 moves forward from the retracted position (Pa) to the deployed position (Pd) by the operation of the handle drive unit 35, and the process by which the opening 30e and the handle entrance / exit 30d2 are shielded by the blind module in conjunction with the movement of the pop-up handle 31.

[0509] For the time being, Figure 12 shows the pop-up handle 31 stopped in the retracted position (Pa).

[0510] When power is supplied to the drive motor 351 from the state shown in Figure 12, the pop-up handle 31 may start moving forward from the retracted position (Pa) towards the deployed position (Pd).

[0511] Referring to Figure 10, when the pop-up handle 31 is moved to the retracted position (Pa) and stopped, power is supplied to the drive motor 351, which then starts operating and generates a rotational driving force in the forward direction.

[0512] This may cause the first output shaft 3512a and the second output shaft 3512b of the drive motor 351 to rotate in the forward direction.

[0513] At this time, when the first output shaft 3512a and the second output shaft 3512b begin to rotate in the positive direction, the first nut 353a, which is screw-connected to the first output shaft 3512a, begins to move linearly to the left, and the second nut 353b, which is screw-connected to the second output shaft 3512b, begins to move linearly to the right.

[0514] 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 moving pin (Pm1), moves to the left.

[0515] Furthermore, as the second nut 353b begins to move linearly to the right, one end of the second drive link 354b1, which is rotatably connected to the second nut 353b via the first moving pin (Pm1), moves to the right.

[0516] At this time, the first drive link 354a1 is connected to one end of the first driven link 354a2 via a third moving pin (Pm3) at an intermediate position.

[0517] Furthermore, the second drive link 354b1 is connected to one end of the second driven link 354b2 via a third moving pin (Pm3) at an intermediate position.

[0518] Therefore, based on the state shown in Figure 12, the first drive link 354a1 will rotate clockwise around the third moving pin (Pm3).

[0519] Furthermore, the second drive link 354b1 rotates counterclockwise as a whole, around the third moving pin (Pm3).

[0520] As the first drive link 354a1 rotates clockwise around the third moving pin (Pm3), the other end of the first drive link 354a1 rotates forward.

[0521] Furthermore, as the second drive link 354b1 rotates counterclockwise around the third moving pin (Pm3), the other end of the second drive link 354b1 rotates forward.

[0522] Since the other end of the first drive link 354a1 is connected to the second handle body 3112 so as to be rotatable relative to it via the second moving pin (Pm2), the rotational force transmitted through the other end of the first drive link 354a1 may be transmitted to the second handle body 3112 via the second moving pin (Pm2).

[0523] Furthermore, since the other end of the second drive link 354b1 is connected to the third handle body 3113 so that the second moving pin (Pm2) can rotate relative to it, the rotational force transmitted through the other end of the second drive link 354b1 may be transmitted to the third handle body 3113 via the second moving pin (Pm2).

[0524] As a result, the second handle body 3112 and the third handle body 3113 may each begin to move forward toward the deployed position (Pd).

[0525] Thus, after the operation of the handle drive unit 35 is started, once the first nut 353a and the second nut 353b have moved to their preset positions, the power supply to the drive motor 351 is interrupted, allowing the pop-up handle 31 to complete its forward movement to the deployed position (Pd).

[0526] Figure 13 shows the state in which the pop-up handle 31 has completed its forward movement to the deployed position (Pd) and stopped.

[0527] Thus, once the pop-up handle 31 has moved forward to its deployed position (Pd), the first handle body 311 can be fully exposed to the outside of the door 30, allowing the user to easily open or close the door 30 while gripping the first handle body 311.

[0528] As shown in Figure 12, a blind panel 371 may be positioned behind the first handle body 311, which moves forward or backward in conjunction with the movement of the first handle body 311.

[0529] As described above, when the pop-up handle 31 is moved to the retracted position (Pa), the opening 30e of the door 30 is closed entirely by the first handle body 311, the second handle body 3112, and the third handle body 3113.

[0530] At this time, when the pop-up handle 31 is moved to the retracted position (Pa), the blind panel 371 is pressurized by the first handle body 311 and can move horizontally to the rearmost position and stop.

[0531] When the vehicle stops in its rearmost position, the compression springs 374 positioned between the blind panel 371 and the first bracket 372, and between the blind panel 371 and the second bracket 373, are in their maximum compressed state, and the maximum restoring force of the compression springs 374 acts on the rear surface of the blind panel 371.

[0532] Therefore, the maximum restoring force of the compression spring 374 may maintain the front end surface 3711a of the blind panel 371 in close contact with the first handle body 311.

[0533] On the other hand, when the pop-up handle 31 begins to move forward from the retracted position (Pa) towards the deployed position (Pd), the restoring force of the compression spring 374 acts, and the blind panel 371 may begin to move horizontally forward from the rearmost position together with the first handle body 311.

[0534] After the pop-up handle 31 begins to move forward from the retracted position (Pa) to the deployed position (Pd), the restoring force of the compression spring 374 causes the blind panel 371 to move together with the pop-up handle 31 until the first handle body 311 passes through the opening 30e of the door 30 and the handle inlet 30d2 of the handle frame 30d, and is completely detached from the opening 30e of the door 30 and the handle inlet 30d2 of the handle frame 30d.

[0535] As the pop-up handle 31 moves further, the first handle body 311 passes through the opening 30e of the door 30 and the handle entrance / exit 30d2 of the handle frame 30d, and moves to a position where it is completely separated from the opening 30e of the door 30 and the handle entrance / exit 30d2 of the handle frame 30d.

[0536] At this time, when the first handle body 311 passes through the opening 30e of the door 30 and the handle entrance / exit 30d2 of the handle frame 30d, and moves to a position where it is completely separated from the opening 30e of the door 30 and the handle entrance / exit 30d2 of the handle frame 30d, the blind panel 371 is moved to the furthest forward position and can stop at the furthest forward position.

[0537] In other words, when the panel body 3711 moves to its furthest forward position, the flange portion 3712, which is integrally formed with the blind panel 371, contacts and collides with the rear end edge of the entrance / exit rib 30d3 of the handle frame 30d, allowing the panel body 3711 to stop at its furthest forward position.

[0538] Thus, the front end surface 3711a of the blind panel 371 in its foremost position may be separated from the first handle body 311 while releasing the state of being in close contact with the first handle body 311.

[0539] Furthermore, when the blind panel 371 stops at its furthest forward position, the compression springs 374 positioned between the blind panel 371 and the first bracket 372, and between the blind panel 371 and the second bracket 373, are in their minimum compressed state, and the minimum restoring force of the compression springs 374 acts on the rear surface of the blind panel 371.

[0540] As mentioned above, when the blind panel 371 is moved to its furthest forward position, the opening 30e of the front panel 30a and the handle entrance / exit 30d2 of the handle frame 30d are obscured by the blind panel 371.

[0541] Furthermore, when the blind panel 371 is moved to its furthest forward position, the front end 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.

[0542] Alternatively, when the blind panel 371 is moved to its furthest forward position, it can stop at a position where it protrudes a predetermined amount from the front surface of the front panel 30a of the door 30.

[0543] Therefore, as shown in Figure 14, the width (Wb) in the front-rear direction (FR direction) between the front end surface 3711a of the blind panel 371 and the flange portion 3712 may be set to be slightly larger than or the same as the width (Wr) in the front-rear direction (FR direction) of the entrance / exit rib 30d3.

[0544] [Detailed configuration and operation of the position deviation adjustment unit] The detailed configuration and operation of the position deviation adjustment units 356a and 356b provided in a dishwasher 1 according to one embodiment of the present invention will be described below with reference to Figures 15 to 17.

[0545] As described above, the present invention generates a rotational driving force for the reciprocating movement of the pop-up handle 31 via a single drive motor 351.

[0546] Therefore, there is a high probability that a positional deviation will occur between the second handle body 3112 and the third handle body 3113 during the reciprocating movement of the pop-up handle 31.

[0547] The position deviation adjustment units 356a and 356b are responsible for minimizing the position deviation between the second handle body 3112 and the third handle body 3113.

[0548] More specifically, as shown in the figure, the position deviation adjustment units 356a and 356b may include a first deviation adjustment unit 356a that adjusts the position of the second handle body 3112 in the front-rear direction (FR direction).

[0549] Furthermore, the position deviation adjustment units 356a and 356b may also include a second deviation adjustment unit 356b that adjusts the position of the third handle body 3113 in the front-rear direction (FR direction).

[0550] As an example, the first deviation adjustment unit 356a may include a first-first shaft 356a1, one end of which is rotatably connected to the second handle body 3112.

[0551] Furthermore, the first deviation adjustment unit 356a may include a first-to-second shaft 356a2, one end of which is connected to the handle frame 30d so as to be rotatable relative to it.

[0552] Furthermore, the first deviation adjustment unit 356a may include a first spring 356a3 that acts as a restoring force to increase the distance between one end of the first-first shaft 356a1 and one end of the first-second shaft 356a2.

[0553] The first-first shaft 356a1 and the first-second shaft 356a2 may be connected to each other in a telescopic manner.

[0554] To enable connection in a telescopic manner, the first-first shaft 356a1 may be a hollow shaft, and the first-second shaft 356a2 into which the first-first shaft 356a1 is joined and inserted may be a hollow rib.

[0555] A first spring 356a3 may be placed inside the first shaft 356a1 in a compressed state.

[0556] In this case, one end of the first shaft 356a1 may be connected to the second handle body 3112 via a movable pin so as to be rotatable relative to it.

[0557] More specifically, one end of the first shaft 356a1 may be connected to the upper end of the aforementioned second moving pin (Pm2) so as to be rotatable relative to the first drive link 354a1.

[0558] Therefore, one end of the first shaft 356a1 can move along the front-rear direction (FR direction) together with the second moving pin (Pm2) when the second handle body 3112 moves.

[0559] Therefore, one end of the first shaft 356a1 may be provided with a ring portion having a circular hole into which the second moving pin (Pm2) is inserted.

[0560] Furthermore, one end of the first-second shaft 356a2 may be connected to the upper end wall 30d12 of the handle frame 30d via a fixing pin (Pf) (not shown) so as to be rotatable relative to it.

[0561] Therefore, one end of the first-to-second shaft 356a2 may be in a state where only relative rotation is possible.

[0562] In this case, if the pop-up handle 31 stops in the retracted position (Pa), one end of the 1-1 shaft 356a1 is positioned further rearward than one end of the 1-2 shaft 356a2 with respect to the front-rear direction (FR direction).

[0563] Therefore, when the pop-up handle 31 stops in the retracted position (Pa), the first deviation adjustment unit 356a will exert a force on the second handle body 3112 that pushes it backward.

[0564] On the other hand, the second deviation adjustment unit 356b may be arranged in a symmetrical shape at a position symmetrical to the first deviation adjustment unit 356a, with respect to a vertical plane that evenly divides the pop-up handle 31 along the horizontal direction.

[0565] Therefore, similar to the first deviation adjustment unit 356a, the second deviation adjustment unit 356b may include a second-first shaft 356b1 and a second-second shaft 356b2 connected to each other in a telescopic manner, and the second spring 356b3 may be arranged inside the second-first shaft 356b1 in a compressed state.

[0566] Furthermore, one end of the second-first shaft 356b1 may be connected to the upper end of the second moving pin (Pm2) described above, together with the second drive link 354b1, so as to be rotatable relative to it.

[0567] Therefore, one end of the second-first shaft 356b1 can move along the front-rear direction (FR direction) together with the second moving pin (Pm2) when the third handle body 3113 moves.

[0568] Therefore, one end of the second-first shaft 356b1 may be provided with a ring portion having a circular hole into which the second moving pin (Pm2) is inserted.

[0569] Furthermore, one end of the second-second shaft 356b2 may be connected to the upper end wall 30d12 of the handle frame 30d via a fixing pin (Pf) (not shown) so as to be rotatable relative to it.

[0570] Therefore, one end of the second-second shaft 356b2 may be in a state where only relative rotation is possible.

[0571] In this case, similar to the first deviation adjustment unit 356a, if the pop-up handle 31 stops in the retracted position (Pa), one end of the second-first shaft 356b1 is positioned further rearward than one end of the second-second shaft 356b2, with reference to the front-rear direction (FR direction).

[0572] Therefore, when the pop-up handle 31 stops in the retracted position (Pa), the second deviation adjustment unit 356b applies a force to the second handle body 3112 that pushes the third handle body 3113 backward.

[0573] However, while one end of the first-1 shaft 356a1 of the first deviation adjustment unit 356a can move along the front-rear direction (FR direction) together with the second handle body 3112, one end of the first-2 shaft 356a2 of the first deviation adjustment unit 356a cannot move along the front-rear direction (FR direction).

[0574] Similarly, one end of the second-first shaft 356b1 of the second deviation adjustment unit 356b is movable along the front-rear direction (FR direction) together with the third handle body 3113, but one end of the second-second shaft 356b2 of the second deviation adjustment unit 356b is immobile along the front-rear direction (FR direction).

[0575] Therefore, the direction of the force acting on the first deviation adjustment unit 356a and the direction of the force acting on the second deviation adjustment unit 356b may differ 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).

[0576] More specifically, the range of movement of the pop-up handle 31 may include a first range of movement formed between the retracted position (Pa) shown in Figures 15 and 16 and intermediate positions where the first deviation adjustment unit 356a and the second deviation adjustment unit 356b are arranged parallel to the extension direction of the first handle body 311.

[0577] Furthermore, the range of movement of the pop-up handle 31 may include a second range of movement formed between the intermediate position and the deployed position (Pd), where the first deviation adjustment unit 356a and the second deviation adjustment unit 356b, shown in Figures 16 and 17, are arranged parallel to the extension direction of the first handle body 311.

[0578] If the position of the pop-up handle 31 falls within the first range of movement, the first deviation adjustment unit 356a will apply a force (F_r) pushing backward to the second handle body 3112, and the second deviation adjustment unit 356b will apply a force (F_r) pushing backward to the third handle body 3113.

[0579] Therefore, if a positional deviation occurs between the second handle body 3112 and the third handle body 3113 within the first range of movement, an even greater force will act on the part of the second handle body 3112 and the third handle body 3113 that has moved further forward, via the first deviation adjustment unit 356a and the second deviation adjustment unit 356b.

[0580] This allows for effective adjustment of the positional deviation between the second handle body 3112 and the third handle body 3113 within the first range of movement.

[0581] At this time, when the pop-up handle 31 moves to the second range of motion while passing through the aforementioned intermediate position, the force of the first deviation adjustment unit 356a and the force of the second deviation adjustment unit 356b are switched from a direction of pushing backward to a direction of pushing forward.

[0582] Therefore, when the position of the pop-up handle 31 falls within the second range of movement, the first deviation adjustment unit 356a applies a forward pushing force (F_f) to the second handle body 3112, and the second deviation adjustment unit 356b applies a forward pushing force (F_f) to the third handle body 3113.

[0583] As a result, if a positional deviation occurs between the second handle body 3112 and the third handle body 3113 in the second range of movement, an even greater force will be applied via the first deviation adjustment unit 356a and the second deviation adjustment unit 356b to the part of the second handle body 3112 and the third handle body 3113 that has been moved insufficiently toward the front.

[0584] This allows for effective adjustment of the positional deviation between the second handle body 3112 and the third handle body 3113 within the first range of movement.

[0585] As described above, the present invention has been explained with reference to the illustrative drawings, but it is clear that the present invention is not limited to the embodiments and drawings disclosed herein, and that various modifications can be made by an ordinary person skilled in the art within the scope of the technical concept of the present invention. Furthermore, even if the effects of the configuration of the present invention are not explicitly described in the embodiments described above, it is natural that the effects that can be predicted by such configuration should also be recognized.
