Description

Technical Field

[0001] The invention relates to a dishwasher. Background Art

[0002] In order to save kitchen space, more and more families choose built-in dishwashers to improve the overall aesthetic effect of the dishwasher in the kitchen. The built-in dishwasher in the prior art includes a door body and a skirting board installed under the door body. The door body is directly installed on the dishwasher body, and the skirting board is directly fixed to the bottom of the dishwasher, or the skirting board of the user's home is borrowed. When installing the door body, there is a certain gap between the door body and the skirting board to avoid the door body and the skirting board from resisting when the dishwasher is opened. However, if the gap between the door body and the skirting board is too large, it will affect the overall aesthetics of the cabinet.

[0003] In response to the above problems, the Chinese invention patent application with patent application number CN201910384561.9 (publication number CN111904351A) discloses "A Embedded Dishwasher", which includes a cabinet, a door assembly installed on the cabinet, and a skirting board. The skirting board is fixed to the cabinet by a connecting mechanism and is linked to the door assembly. The outer side surface of the door assembly in a closed state is flush with the outer side surface of the skirting board, and the door assembly drives the skirting board to flip when it is opened. The door assembly and the skirting board in the present invention are linked. When the door assembly is opened, the skirting board performs the same action as the door assembly, effectively avoiding the problem of interference between the door assembly and the skirting board when it is opened, reducing the matching gap between the door assembly and the skirting board in a closed state, and significantly improving the overall aesthetics of the dishwasher.

[0004] The skirting board and the door assembly of this patent are linked to each other so that when the door assembly is closed, the gap between the skirting board and the door assembly is small, and the skirting board will not interfere with the door assembly when the door is opened. However, an embedded dishwasher usually has an exhaust pipe on the door body to discharge the hot steam in the cabinet during the drying stage from the exhaust pipe, such as the Chinese utility model patent with patent application number CN202321474862.9 (publication number CN220024969U) disclosed in "A sensor installation structure for a dishwasher and a dishwasher". It can be seen from the figure that the exhaust port of the exhaust pipe is located below the door body. If there is no gap between the skirting board and the door body, the skirting board will block the exhaust port of the exhaust pipe, affecting the exhaust of the exhaust pipe. If there is a gap between the skirting board and the door body, the exhausted gas will blow directly to the user, and the high-temperature water vapor can easily scald the user. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a dishwasher capable of preventing the airflow flowing out of the exhaust pipe from directly blowing on the user in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a dishwasher which can reduce the gap between the door body and the skirting board and does not affect the opening and closing of the door body in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a dishwasher, comprising

[0008] A box body, the front side of which is open to form an opening;

[0009] The door body is arranged at the opening of the box body so as to be rotatable forward and backward, thereby opening or closing the opening, and an exhaust hole is arranged on the inner wall surface of the door body;

[0010] An exhaust pipe is arranged on the door body, an air inlet of the exhaust pipe is connected with an exhaust hole of the door body, and an exhaust port of the exhaust pipe faces forward and is located below the door body in a closed state;

[0011] The skirting board is located at the lower part of the box;

[0012] It is characterized in that the skirting board can be in a first position, and the skirting board in the first position has the following positional relationship with the door body in a closed state: the skirting board is located directly in front of the exhaust port of the exhaust pipe, and in addition, the skirting board is located in front of the door body, and the skirting board and the door body form an exhaust gap in the front-to-back direction for connecting the exhaust port with the outside world, and at this time, the skirting board is outside the path of the door body rotating from a closed state to an open state.

[0013] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: the skirting board can also be in a second position, and the skirting board in the second position has the following positional relationship with the door body in a closed state: the skirting board is located below the door body and directly in front of the exhaust port of the exhaust pipe, and at this time the skirting board is located on the path of the door body rotating from a closed state to an open state.

[0014] Preferably, the skirting board in the second position and the door body in the closed state also have the following positional relationship: the top of the skirting board is in contact with the bottom of the door body, and the outer wall surface of the skirting board is flush with the outer wall surface of the door body, further improving the integrity of the dishwasher and improving its aesthetics.

[0015] In order to position the skirting board relative to the box body when the skirting board is in the second position, the skirting board and the guide plate are detachably connected via an insert block and a slot, and the insert block extends in the front-to-back direction. The cooperation of the insert block and the slot can not only realize the positioning of the guide plate of the skirting board, but also will not affect the movement of the skirting board from the second position to the first position.

[0016] The first position of the skirting board is located obliquely above and in front of the second position, so in order to guide the movement trajectory of the skirting board, a guide plate is fixedly provided on the box body, and a guide groove is provided on the guide plate. The guide groove extends from the back to the front and upward, and a guide block that can slide along the guide groove is provided on the skirting board. The guide groove extends obliquely from the back to the front, so that when the skirting board moves, it slides along the trajectory of the guide groove.

[0017] The guide groove may be a straight line segment, or may be an arc-shaped structure arched from back to front and downward.

[0018] In order to drive the skirting board to move so that the skirting board switches between the first position and the second position, the dishwasher further comprises a driving mechanism for driving the skirting board to switch between the first position and the second position, and the driving mechanism is drivingly connected to the skirting board.

[0019] The driving mechanism can have various structural forms. Preferably, the driving mechanism includes a driving member and a top rod driven by the driven member to move along the front-to-back direction. A vertically extending limit groove is provided on the inner wall surface of the skirting board. The front end of the top rod is a limit block. The limit block is constrained in the limit groove and can produce relative displacement with the skirting board in the up and down directions.

[0020] The driving member can be an electric push rod, or it can be a push rod. A plurality of teeth are arranged in sequence along the front-to-back direction on the push rod to form a rack. The output shaft of the driving member is a worm gear, and the worm gear and the rack are connected by a gear transmission. The gear transmission method has a compact structure and occupies little space.

[0021] When the skirting board is in the first position, it will not interfere with the opening of the door body. If the user does not operate in advance to move the skirting board to the first position and suddenly opens the door, the driving member cannot operate because the top rod is locked, causing the door body to interfere with the skirting board when it opens and fail to open normally. To solve this problem, a linkage member is provided between the door body and the skirting board. When the skirting board is in the second position and the door body is driven to open, the door body drives the linkage member to move, and the linkage member pushes the skirting board from the second position toward the first position. In this way, during the opening process of the door body, the linkage member will push the skirting board to the first position to prevent the skirting board from interfering with the door body.

[0022] Because the front end of the push rod is constrained in the limit groove, in order to prevent the skirting board from being unable to move due to the constraint of the push rod when the linkage drives the skirting board, when the skirting board is in the second position, there is a gap between the limit block of the push rod and the rear wall of the limit groove so that the skirting board can move forward to the first position relative to the push rod.

[0023] The linkage member can have a variety of structural forms, and the structure is simple. The linkage member includes a first rod and a second rod. The first end of the first rod is connected to the first end of the second rod, and the connection between the two is installed on a mounting shaft extending in the left-right direction and can rotate around the mounting shaft. The second end of the first rod is located on the moving path of the door body opening, and the skirting board in the second position is located on the moving path of the second end of the second rod. During the door body opening process, the first rod is pushed to rotate the linkage member, so that the second rod pushes the skirting board to move toward the first position.

[0024] Preferably, the dishwasher is provided with a human sensor and a controller, the human sensor is electrically connected to the input end of the controller, the output end of the controller is electrically connected to the driving mechanism, and the driving mechanism can control the movement of the skirting board. In this way, the skirting board can be placed in different positions according to the different positions of the user, so as to minimize the risk of scalding of the user and improve the user experience.

[0025] Preferably, the dishwasher further comprises a door opening signal transmitter, a controller and a door opening mechanism capable of pushing the door body to open, the door opening signal transmitter is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the door opening mechanism and the driving mechanism.

[0026] Compared with the prior art, the advantages of the present invention are as follows: the present invention forms an exhaust gap between the skirting board and the door body in the front-to-rear direction to connect the exhaust port with the outside world, so that the airflow in the exhaust pipe flows out of the exhaust port and flows upward from the exhaust gap, and will not blow directly forward to the user, thereby preventing the user from being scalded. At this time, the skirting board is located outside the path of the door body rotating from the open state to the closed state, and the skirting board will not affect the opening of the door body.

[0027] In addition, the skirting board can also be in the second position. When the door does not need to be opened or the exhaust does not need to be vented, the skirting board can be in the second position. The dishwasher has good integrity and compact structure, and the skirting board prevents the user from kicking the cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention is further described in detail below with reference to the accompanying drawings.

[0037] like Figures 1 to 8 As shown, the dishwasher of this preferred embodiment includes a cabinet 1, a door 2, an exhaust pipe 3, a skirting board 4 and a driving mechanism 6.

[0038] like Figure 1 , 6 As shown, the front side of the box body 1 is open to form an opening 11, and the door body 2 is arranged at the opening 11 of the box body 1 so as to be rotatable forward and backward, thereby opening or closing the opening 11. An exhaust hole 12 is arranged on the inner wall surface of the door body 2, and an exhaust pipe 3 is arranged on the door body 2. The air inlet of the exhaust pipe 3 is connected to the exhaust hole 12 of the door body 2, and the exhaust port 31 of the exhaust pipe 3 faces forward and is located below the door body 2 in the closed state, so as to discharge the hot and humid gas in the box body 1. This is a prior art and will not be described in detail here.

[0039] The skirting board 4 is located at the lower part of the box body 1, and the skirting board 4 can be in a first position and a second position.

[0040] like Figure 8 As shown, the skirting board 4 in the first position and the door body 2 in the closed state have the following positional relationship: the skirting board 4 is located directly in front of the exhaust port 31 of the exhaust pipe 3. In addition, the skirting board 4 is located in front of the door body 2 and the two are partially overlapped in the front-to-back direction, so that the skirting board 4 and the door body 2 form an exhaust gap 41 in the front-to-back direction for connecting the exhaust port 31 with the outside world, so that after the airflow in the exhaust pipe 3 flows out from the exhaust port 31, it flows upward from the exhaust gap 41 and will not blow forward directly to the user, thereby preventing the user from being scalded. At this time, the skirting board 4 is located outside the path of the door body 2 rotating from the closed state to the open state, and will not affect the opening of the door body 2.

[0041] like Figure 1As shown, the skirting board 4 in the second position has the following positional relationship with the door body 2 in the closed state: the skirting board 4 is located below the door body 2 and directly in front of the exhaust port 31 of the exhaust pipe 3, the top of the skirting board 4 is in contact with the bottom of the door body 2 (that is, there is a very small gap or no gap between the two), and the outer wall surface of the skirting board 4 is flush with the outer wall surface of the door body 2, so that the dishwasher has good integrity and aesthetics, and at this time, the skirting board 4 is located on the path of the door body 2 rotating from the closed state to the open state, and the skirting board 4 will interfere with the opening of the door body 2.

[0042] From the above, it can be seen that when the skirting board 4 is in the second position, the opening of the door body 2 will interfere with the skirting board 4, affecting the opening of the door body 2. When the skirting board 4 is moving toward the first position or is in the first position, the opening of the door body 2 will not interfere with the skirting board 4, and the door body 2 can be opened normally.

[0043] The first position of the skirting board 4 is located obliquely above the front side of the second position, so in order to guide the movement trajectory of the skirting board 4, as shown in FIG. Figure 1 , 4 As shown in Figures 1 and 5, a guide plate 5 is fixedly provided on the box body 1, and a guide groove 51 is provided on the guide plate 5. The guide groove 51 extends from the back to the front and upwards. A guide block 42 that can slide along the guide groove 51 is provided on the skirting board 4. In this embodiment, a mounting plate 40 extending in the front-to-back direction is provided on the inner wall surface of the skirting board 4, and the guide block 42 is provided on the mounting plate 40. In this article, the inner wall surface of the skirting board 4 and the inner wall surface of the door body 2 refer to the side facing the opening 11 of the box body 1, and the outer wall surface refers to the side away from the opening 11 of the box body 1.

[0044] The guide groove 51 extends obliquely from the back to the front, so that when the skirting board 4 moves, it slides along the track of the guide groove 51. The guide groove 51 can be a straight line segment. In this embodiment, the guide groove 51 is an arc-shaped structure that arches downward from the back to the front.

[0045] When the skirting board 4 is in the second position, the skirting board 4 and the guide plate 5 are detachably connected via the insert block 43 and the slot 52. The insert block 43 extends in the front-to-back direction. The cooperation between the insert block 43 and the slot 52 can not only realize the positioning of the guide plate 5 of the skirting board 4, but also will not affect the movement of the skirting board 4 from the second position to the first position.

[0046] like Figure 4 , 7As shown, the driving mechanism 6 is connected to the skirting board 4 to drive the skirting board 4 to switch between the first position and the second position. The driving mechanism 6 includes a driving member 61 and a push rod 62 driven by the driving member 61 to move in the front-to-back direction. The push rod 62 is provided with a plurality of teeth in sequence in the front-to-back direction to form a rack 63. The output shaft of the driving member 61 is a worm 64. The worm 64 and the rack 63 are connected by a gear 65. The gear 65 can be one or at least two meshing gears.

[0047] A vertically extending limit groove 44 is provided on the inner wall surface of the skirting board 4, and a limit block 621 is provided at the front end of the push rod 62. The limit block 621 is constrained in the limit groove 44 and can produce relative displacement in the vertical direction with the skirting board 4. The driving member 61 can be a motor, which drives the worm 64 to rotate, and transmits power to the rack 63 through the gear 65, so that the push rod 62 moves forward and backward to push the skirting board 4 forward or pull it backward. Because the skirting board 4 has an upward movement when moving forward, the push rod 62 and the skirting board 4 will be displaced in the vertical direction.

[0048] If the user does not operate in advance to move the skirting board 4 toward the first position, that is, the skirting board 4 is in the second position and the user suddenly opens the door, the driving member 61 locks the top rod 62 and cannot operate, causing the door body 2 to interfere with the skirting board 4 when it is opened and fail to open normally. To solve this problem, a linkage member 7 is provided between the door body 2 and the skirting board 4. When the skirting board 4 is in the second position and the door body 2 is driven to open, the door body 2 drives the linkage member 7 to move, and the linkage member 7 pushes the skirting board 4 to move from the second position toward the first position.

[0049] In this embodiment, the linkage member 7 includes a first rod body 71 and a second rod body 72. The first end of the first rod body 71 is connected to the first end of the second rod body 72, and the connection between the two is installed on the installation shaft 53 extending in the left-right direction and can rotate around the installation shaft 53. The installation shaft 53 is fixedly connected to the guide plate 5. The second end of the first rod body 71 is located on the moving path of the door body 2 when it is opened, and the skirting board 4 in the second position is located on the moving path of the second end of the second rod body 72. The installation shaft 53 can be provided with a limit block 73 that can abut against the first rod body 71 to limit the rotation stroke of the linkage member 7. During the opening process of the door body 2, the first rod body 71 is pushed to rotate the linkage member 7, so that the second rod body 72 pushes the skirting board 4 to move toward the first position to prevent the skirting board 4 from interfering with the door body 2.

[0050] Because the front end of the push rod 62 is constrained in the limiting groove 44, in order to prevent the skirting board 4 from being unable to move due to the constraint of the push rod 62 when the linkage 7 drives the skirting board 4, when the skirting board 4 is in the second position, there is a gap between the limiting block 621 of the push rod 62 and the rear wall of the limiting groove 44 so that the skirting board 4 can move forward to the first position relative to the push rod 62.

[0051] The dishwasher of this embodiment is also provided with a human sensor, a controller, a door opening signal transmitter and a door opening mechanism capable of pushing the door body 2 to open. Of course, these structures may not be provided.

[0052] The human sensing device is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the driving mechanism 6, which can control the movement of the skirting board 4. In this way, the skirting board 4 can be placed in different positions according to the different positions of the user, so as to minimize the risk of scalding of the user and improve the user experience. The human sensing device adopts an existing structure, such as infrared sensing.

[0053] The door opening signal transmitter is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the door opening mechanism and the driving mechanism 6. The door opening signal transmitter can use a knocking module, etc. The cooperation between the door opening signal transmitter, the controller and the door opening mechanism can refer to the "A Dishwasher with Automatic Door Opening by Knocking" disclosed in the Chinese utility model patent with application number CN202321941890.7 (Announcement number CN220675946U). When the user needs to open the door, knock on the door body 2, and the door opening signal transmitter sends a signal to the controller. The controller controls the driving mechanism 6 and the door opening mechanism to work, and the skirting board 4 moves toward the first position, which will not affect the opening of the door body 2. The door body 2 opens under the action of the door opening mechanism. When closing the door, the working process is the same.

[0054] The electrical connections between the above components and the controller all adopt existing electrical connection methods, which will not be repeated here.

[0055] In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom" and "vertical" are used interchangeably.

[0056] The directions or positional relationships indicated by "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for explanation and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
