Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to an electrical appliance. Background Art

[0002] Appliances such as steam ovens and dishwashers all consist of a main body and a door located on the front of the main body. The door can be opened or closed relative to the main body, thereby exposing or closing the internal space of the appliance. To ensure the stability of the door when closed, the main body is usually equipped with a door lock device, and the door is equipped with a lock component that cooperates with the door lock device. When the door is closed, the door lock device and the lock component cooperate to lock, preventing the door from being opened at will while the appliance is in operation.

[0003] In the prior art, to achieve automatic door opening and closing of a machine door, a door lock device includes a door lock component and a door lock driver. The door lock driver drives the door lock component to switch between a locked position in which it can be locked with the lock component and an unlocked position in which it is unlocked from the lock component, thereby achieving automatic locking and unlocking of the machine door. However, with this arrangement, since the door lock driver drives the door lock component to switch between the unlocked position and the locked position, when opening the door, the user must first send an unlocking instruction to the appliance controller, prompting the controller to control the door lock driver to operate, so that the door lock driver drives the door lock component to the unlocked position. This increases the user's waiting time and reduces the user experience. If the user forgets to send the unlocking instruction to the appliance and directly closes the door, the lock component is likely to collide with the door lock component in the locked position. Multiple collisions can easily cause the door lock component or the lock component to deform, affecting the reliability of opening and closing the door.

[0004] Therefore, there is an urgent need for an electrical appliance to solve the above-mentioned technical problems. Utility Model Content

[0041] Example 1

[0042] This embodiment provides an electrical appliance that can realize automatic door opening and closing operations of the electrical appliance, thereby improving the reliability and convenience of automatic door opening and closing.

[0043] Specifically, if Figures 1 to 3As shown, the appliance includes a body and a door 400 movably mounted on the front side of the body, a lock component 200 is provided on the door 400, and the appliance also includes a door lock 1, which is rotatably mounted on the body and includes a lock hook 11. The door lock 1 can switch between a locked position in which the lock hook 11 cooperates with the lock component 200 and an unlocked position in which the lock hook 11 can disengage the lock component 200. The lock component 200 in the locked position can be pressed and rotated by the lock component 200 during the closing process of the door 400, so that the door lock 1 is rotated to the unlocked position for the lock component 200 to be engaged with the lock hook 11. The door lock 1 in the unlocked position can be restored to the locked position.

[0044] The appliance provided in this embodiment provides a lock component 200 and a door lock component 1 on the machine door 400, so that the locking of the lock component 200 and the door lock component 1 can achieve the locking of the machine door 400 relative to the machine body, thereby ensuring that the machine door 400 is not opened at will and affects the normal operation of the appliance; because the lock component 200 can push the lock hook 11 during the closing process of the machine door 400, the door lock component 1 can be rotated to the unlocked position for the lock component 200 to be engaged with the lock hook 11, and after the door lock component 1 is rotated to the unlocked position, it can automatically reset to the locked position, so that the user can automatically achieve the locking of the lock component 200 and the door lock component 1 after closing the machine door 400, without the need for additional operation, and the automatic door closing operation is convenient and reliable, thereby improving the flexibility of use of the appliance.

[0045] Specifically, if Figure 2 and Figure 5 As shown, the lock hook 11 has a lock slot 111. When the door lock 1 is in the unlocked position, the notch of the lock slot 111 faces forward, so that the lock component 200 can move in and out of the lock slot 111 along the front and rear directions, so that the machine door 400 can be opened relative to the machine body. When the door lock 1 is in the locked position, the notch of the lock slot 111 faces left and right to limit the lock component 200 from moving forward and out of the lock slot 111.

[0046] Furthermore, a guide surface 112 is formed on the front side of the lock hook 11. The guide surface 112 is located on the front side of the lock slot 111 and extends forward from the notch of the lock slot 111 in a direction away from the notch of the lock slot 111. When the user closes the door and the lock hook 11 is in the locked position, the lock component 200 first contacts the guide surface 112. During the process of the user closing the door, the lock component 200 pushes the guide surface 112 from front to back, causing the lock hook 11 to rotate in the direction toward the unlocked position, thereby guiding the lock component 200 to enter the lock slot 111 of the lock hook 11.

[0047] In this embodiment, the lower end of the door 400 is hinged to the machine body via a hinge mechanism 1000. The lock component 200 is mounted in the middle of the upper end of the door 400 in the left-right direction, and the door lock component 1 is mounted in the middle of the machine body in the left-right direction. This improves the force balance during the opening and closing of the door 400. In other embodiments, the door 400 can be hinged to the machine body on one side in the left-right direction, while the lock component 200 is mounted on the other side of the door 400, with the door lock component 1 mounted in a position that matches the lock component 200.

[0048] like Figure 3 and Figure 4 As shown, in order to realize the automatic door opening operation, the appliance also includes a door lock driving mechanism 3 and an elastic reset member 5. The door lock driving mechanism 3 is transmission-connected to the door lock member 1 to drive the door lock member 1 to rotate from the locked position to the unlocked position. The elastic reset member 5 always applies an elastic force to the door lock member 1 to rotate or maintain the door lock member 1 in the locked position.

[0049] That is, when the door lock driving mechanism 3 is not in action, the door lock component 1 is maintained in the locked position under the elastic force of the elastic return component 5, and the machine door 400 is stably closed; when the door needs to be opened, the door lock driving mechanism 3 is operated, so that the door lock driving mechanism 3 drives the door lock component 1 to rotate from the locked position to the unlocked position, the lock component 200 can be disengaged from the lock hook 11, and the user can perform the door opening operation; after the user opens the door, the door lock component 1 returns to the locked position again under the elastic force of the elastic return component 5; when the user closes the door, the door lock component 1 rotates to the unlocked position under the pressure of the lock component 200 so that the lock component 200 is stuck in the lock groove 111 of the lock hook 11; after the machine door 400 is closed, the door lock component 1 returns to the locked position under the elastic force of the elastic return component 5.

[0050] In this embodiment, the door lock drive mechanism 3 includes a drive assembly 31, a slider 32, and a connecting rod 33. The drive assembly 31 drives the slider 32 to slide in a predetermined direction. The first end of the connecting rod 33 is connected to the slider 32, and the second end of the connecting rod 33 is hinged to the door lock component 1 via a hinge shaft 4. The hinge shaft 4 is parallel to and spaced apart from the rotation axis of the door lock component 1. The sliding of the slider 32 drives the connecting rod 33, thereby driving the door lock component 1 to rotate about its axis. This arrangement increases the flexibility of the positioning of the drive assembly 31, thereby improving the installation convenience of the door lock drive mechanism 3. In this embodiment, the slider 32 slides in a left-right direction, the connecting rod 33 is arranged roughly in the left-right direction, and the drive assembly 31 is installed on one side of the top space in the left-right direction.

[0051] However, it is understandable that in other embodiments, the door lock drive mechanism 3 can also adopt other structural forms, as long as the door lock drive mechanism 3 can ensure that the door lock component 1 can rotate around its axis. The present invention does not limit the specific structure of the door lock drive mechanism 3 and its installation structure in the top space.

[0052] It is worth noting that in this embodiment, the lower end of the door 400 is hinged to the main body via a hinge mechanism 1000. The hinge mechanism 1000 constantly applies an elastic force to the closed door 400, causing it to flip outward relative to the main body. Consequently, when the door lock device 100 and the lock component 200 are unlocked, the door 400 automatically flips outward under the elastic force of the hinge mechanism 1000, achieving automatic opening of the door 400. This improves the convenience of opening the cooking device door and enhances the user experience and convenience of the cooking device. In other embodiments, the door 400 may only be opened manually by the user.

[0053] like Figure 5 and Figure 6 As shown, since the lock component 200 needs to push the guide surface 112 of the lock hook 11 to push the door lock component 1 to rotate to the unlocked position when the machine door 400 is closed, if the front end of the lock hook 11 is far back relative to the design position, the lock component 200 may not be able to push the door lock component 1 to rotate, and then the machine door 400 cannot be closed smoothly. Even if the components can be stuck in the lock hook 11, the lock hook 11 may pull the machine door 400 backward, resulting in a large interference fit between the door seal on the front side of the machine body and the machine door 400, which in turn leads to a problem that the force required to close the door increases, affecting the user's door closing experience; if the front end of the lock hook 11 is far forward relative to the design position, the door lock component 1 may squeeze the machine door 400 forward after being locked with the lock component 200, and then the interference fit between the door seal on the front side of the machine body and the door body is too small, resulting in air leakage.

[0054] To address the above-mentioned issues, in this embodiment, the appliance further includes an adjustment assembly 2 for adjusting the front-to-back position of the door lock 1 relative to the appliance body. By providing the adjustment assembly 2, the adjustment assembly 2 can adjust the front-to-back position of the door lock 1, thereby adjusting the position of the front end of the lock hook 11. This prevents the front end of the lock hook 11 from misaligning with the preset installation position due to manufacturing errors or installation errors between the lock component 200 and the door lock 1, thereby ensuring that the lock component 200 and the door lock 1 can cooperate smoothly and reliably, thereby improving the reliability of automatic door opening and closing.

[0055] like Figures 7 to 10As shown, in order to improve the installation and adjustment convenience of the door lock 1, in this embodiment, the adjustment assembly 2 includes an adjustment seat 21 and an adjustment fastener 26. The adjustment seat 21 can be slidably installed on the body in the front-to-back direction, and the door lock 1 is rotatably installed on the adjustment seat 21. The adjustment fastener 26 fastens the adjusted adjustment seat 21 relative to the body. By providing the adjustment seat 21, the door lock 1 can be adjusted by sliding the adjustment seat 21 relative to the body, so that the body and the adjustment seat 21 slide together, while the door lock 1 and the adjustment seat 21 rotate together, simplifying the matching structure and ensuring the installation convenience of the door lock 1. At the same time, by providing the adjustment fastener 26, the adjusted adjustment seat 21 can be fastened relative to the body, preventing the adjustment seat 21 from shifting relative to the body during use of the appliance, thereby ensuring the reliability of the door lock 1 and the appliance.

[0056] In this embodiment, the electrical appliance includes an inner liner 300, a casing 1100 arranged on the outside of the inner liner 300, and a front frame 500 arranged on the outside of the front end of the inner liner 300. A control panel 800 is installed on the upper end of the front frame 500. The control panel 800 is higher than the inner liner 300. A top support plate 600 is provided on the top of the inner liner 300. The door lock 1 and the door lock drive mechanism 3 are installed in the top space formed by the casing 1100, the control panel 800 and the top support plate 600, and the lock hook 11 extends out of the top space to cooperate with the lock component 200.

[0057] Furthermore, the control panel 800 is mounted to the front frame 500 via a panel bracket 801. The panel bracket 801 extends forward from the front side of the inner container 300, allowing the control panel 800 to extend forward from the front side of the inner container 300. When the appliance door 400 is closed, the door 400 is located below the control panel 800, and the front side of the door 400 is roughly flush with the front side of the control panel 800, ensuring the overall aesthetics of the appliance.

[0058] It is worth noting that the specific structural settings of the machine body and the door 400 can be set with reference to the existing technology. This is not the focus of this embodiment, and this embodiment does not limit or elaborate on it.

[0059] In the embodiment, the adjustment seat 21 is rotatably mounted on the panel bracket 801, and the door lock component 1 extends through the lower side of the panel bracket 801. This allows the door lock component 1 and the adjustment seat 21 to be installed forward, thereby ensuring that the lock hook 11 can cooperate with the lock component 200 while reducing the size of the door lock component 1 and the adjustment assembly 2. Specifically, the panel bracket 801 has a front plate portion and side plates perpendicularly arranged around the sides of the front plate portion. The side plate portion located on the lower side is the lower side plate portion 8011. The adjustment seat 21 is mounted on the lower side plate portion 8011, and the lower side plate portion 8011 is provided with a mounting hole 8012. The door lock component 1 extends through the lower side plate portion 8011 through the mounting hole 8012.

[0060] To enhance the ease of installation and adjustment of the door lock 1, an axis through-hole 215 is defined in the adjustment base 21. The door lock 1 also includes a lock shaft 12. A lock hook 11 is fixedly connected to the first section of the lock shaft 12. The lock shaft 12 rotates through the axis through-hole 215 and engages with the axis through-hole 215, thereby radially confining the lock shaft 12 within the axis through-hole 215. This configuration allows the shape of the lock hook 11 to be configured solely to accommodate the lock component 200. While ensuring that the lock hook 11 is positioned outside the housing, it also facilitates the door lock 1 from protruding from the housing, enhancing the ease of installation of the door lock 1. Specifically, the lock shaft 12 is inserted into the mounting hole 8012 on the lower side plate 8011. In other embodiments, the rear end of the lock hook 11 is rotatably connected to the adjustment base 21, so that the lock hook 11 protrudes from the housing and engages with the lock component 200.

[0061] In this embodiment, the lock shaft 12 is vertically arranged to improve the installation convenience of the lock shaft 12. In other embodiments, the lock shaft 12 can also be tilted relative to the vertical direction, such as the lock shaft 12 is tilted forward from top to bottom.

[0062] To improve the installation convenience of the adjustment seat 21, the adjustment assembly 2 also includes a fixed seat 22, which is installed on the machine body and has an avoidance shaft hole 2211. The adjustment seat 21 is slidably installed on the fixed seat 22, and the lock shaft 12 can be movably passed through the avoidance shaft hole 2211 in the front-to-back direction. The adjustment fastener 26 fastens the fixed seat 22 and the adjustment seat 21. By providing the fixed seat 22, the matching structure of the adjustment seat 21 and the machine body can be simplified, which is more conducive to the structural setting of the sliding installation structure of the adjustment seat 21, ensuring the smoothness and reliability of the sliding of the adjustment seat 21. In other embodiments, the adjustment seat 21 can also be directly slidably installed on the machine body. Specifically, the adjustment seat 21 is slidably installed on the lower side plate portion 8011.

[0063] Specifically, in this embodiment, the fixing seat 22 is detachably mounted on the upper side of the lower plate portion 8011, and the adjustment seat 21 is slidably mounted on the upper side of the fixing seat 22. To ensure the stability of the adjustment seat 21 after adjustment, an adjustment fastener 26 is provided on each side of the lock shaft 12.

[0064] In order to improve the sliding reliability of the adjustment seat 21, one of the adjustment seat 21 and the fixed seat 22 is provided with a sliding groove 219, and the other is provided with a sliding protrusion 222. The sliding protrusion 222 is slidably set in the sliding groove 219, and the sliding groove 219 extends along the front and rear directions, thereby providing guidance for the sliding of the adjustment seat 21 along the front and rear directions.

[0065] In this embodiment, the fixed seat 22 includes a main seat portion 221, with a sliding protrusion 222 protruding from the upper side of the main seat portion 221. Two sliding protrusions 222 are provided at intervals along the left-right direction. A sliding groove 219 is defined at the bottom of the adjustable seat 21. The two sliding protrusions 222, with their sides facing away from each other, slide in engagement with the opposing walls of the sliding groove 219. In other embodiments, the sliding protrusions 222 and the sliding grooves 219 may be provided in a one-to-one correspondence, with the left and right side walls of each sliding protrusion 222 sliding in engagement with the opposing side walls of the sliding groove 219.

[0066] Furthermore, the adjustment seat 21 includes a main plate portion 211, which is recessed downward to form a recessed portion 212. Two recessed portions 212 are spaced apart in the left-right direction, with a sliding groove 219 formed between the two recessed portions 212. The bottom of the recessed portion 212 slides in contact with the main seat portion 221. An adjustment fastening hole 2121 is formed through the bottom of the recessed portion 212, and a fixing fastening hole 2213 is formed on the fixed seat 22. At least one of the adjustment fastening hole 2121 and the fixing fastening hole 2213 is an elongated hole. The fixed seat 22 and the adjustment seat 21 are connected by an adjustment fastener 26 that passes through the adjustment fastening hole 2121 and the fixing fastening hole 2213. This facilitates the processing and formation of the sliding groove 219 while improving the connection convenience between the adjustment seat 21 and the fixed seat 22. Furthermore, the adjustment fastening hole 2121 is an elongated hole.

[0067] The four sides of the main plate portion 211 are further connected to the surrounding edge portions 213 . The surrounding edge portions 213 are used to block the gap between the main plate portion 211 and the seat main portion 221 and to improve the overall structural strength and rigidity of the adjustment seat 21 .

[0068] A boss portion 216 is formed on at least one of the upper and lower sides of the main plate portion 211. The shaft through-hole 215 extends through the boss portion 216 and the main plate portion 211. This increases the length of the shaft through-hole 215, thereby increasing the mating length between the adjustment seat 21 and the lock shaft 12, and improving the rotation and installation stability of the lock shaft 12. In this embodiment, boss portions 216 are formed on both the upper and lower sides of the main plate portion 211. The boss portion 216 on the upper side is the upper boss portion 216b, and the boss portion 216 on the lower side is the lower boss portion 216a.

[0069] In this embodiment, the end of the lock shaft 12 away from the lock hook 11 passes through the adjustment seat 21, and the lock shaft 12 is detachably provided with a first shaft limiter 14, which is pressed against the side of the adjustment seat 21 away from the lock hook 11, thereby limiting the lock shaft 12 from moving downward relative to the adjustment seat 21 and escaping from the adjustment seat 21, further ensuring the setting stability and reliability of the lock shaft 12.

[0070] The second end of the lock shaft 12 is detachably connected to a connector 13, which is in transmission connection with the door lock drive mechanism 3 to facilitate the door lock drive mechanism 3 to rotate the door lock member 1. The second end of the lock shaft 12 is detachably connected to a second shaft stopper 15, which is sandwiched between the first shaft stopper 14 and the second shaft stopper 15 to limit the relative position of the connector 13 and the lock shaft 12 in the axial direction. At the same time, the cooperation between the connector 13 and the door lock drive mechanism 3 can further limit the relative position of the lock shaft 12 and the adjustment seat 21 in the upward direction of the lock shaft 12.

[0071] Furthermore, the lock shaft 12 comprises a coaxially connected optical shaft segment and a screw segment. The optical shaft segment is inserted into the shaft through-hole 215, and the end of the optical shaft segment away from the screw segment is connected to the locking hook 11. The screw segment extends upward from the upper side of the adjustment seat 21. The first and second shaft stoppers 14, 15 are nuts that are threaded onto the screw segment. This simplifies the arrangement of the first and second shaft stoppers 14, 15.

[0072] Furthermore, a shaft limiting portion 121 is protruding from the lock shaft 12. The shaft limiting portion 121 is located on the side of the fixing seat 22 away from the adjusting seat 21 and is located outside the machine body. The shaft limiting portion 121 is restricted from passing through the hole on the machine body for installing the lock shaft 12 to restrict the lock shaft 12 from moving upward until the entire body enters the interior of the machine body.

[0073] In this embodiment, the appliance is a steam cooking device, namely, it includes a steam cooking module that provides hot steam into the inner pot 300 to cook the food inside. To facilitate the discharge of steam from the inner pot 300, the appliance body also includes a hood 700 located at the top of the inner pot 300. The hood 700 defines a heat dissipation duct that communicates with the inner pot 300 and has an exhaust port 701. During or after cooking, the steam inside the inner pot 300 is discharged into the heat dissipation duct and then out through the exhaust port 701. Furthermore, a heat dissipation fan 900 is located at the top of the inner pot 300. The heat dissipation fan 900 directs external cooling air into the heat dissipation duct to cool and dissipate the hot steam, thereby preventing the steam from overheating and potentially scalding the user. In other embodiments, the appliance may also be a dishwasher, a disinfection cabinet, or other appliance requiring automatic door opening and closing.

[0074] The front end of the air hood 700 has an exhaust port 701 for the heat dissipation air duct, and the adjustment component 2 is arranged at the front end of the air hood 700. In order to prevent the gas discharged from the exhaust port 701 from entering the top space through the mounting hole 8012 of the lower side plate 8011, in this embodiment, the adjustment component 2 includes a first seal 23, and the first seal 23 is sleeved on the outer side of the lock shaft 12 and fixed relative to the adjustment seat 21. The first seal 23 stops the gas from flowing along the axial direction of the lock shaft 12, and the first seal 23 stops the gas from flowing along the gap between the adjustment seat 21 and the sliding mounting surface for installing the adjustment seat 21.

[0075] The setting of this first sealing member 23 can seal the gap between the adjustment seat 21 and the sliding mounting plane of the adjustment seat 21, thereby preventing the airflow from flowing into the top space along the gap, and can also stop the airflow from entering the top space along the axial direction of the lock shaft 12, with a better sealing effect; thereby preventing steam from corroding the door lock drive mechanism 3 and other structures in the top space, ensuring the safety of the cooking equipment, and improving the installation convenience of the door lock device 100.

[0076] In another embodiment, the first seal 23 may only block airflow along the axial direction of the lock shaft 12, while the clearance between the adjustment seat 21 and its sliding mounting surface is controlled by the fitting clearance therebetween to limit airflow in the clearance. In another embodiment, the first seal 23 may only block airflow along the clearance between the adjustment seat 21 and the sliding mounting surface, while the clearance between the adjustment seat 21 and the lock shaft 12 is set by the fitting clearance to reduce the probability of airflow flowing into the head space through the clearance.

[0077] Specifically, in this embodiment, the upper side of the fixed seat 22 forms the sliding mounting surface for the adjustable seat 21. That is, the first seal 23 is sandwiched between the fixed seat 22 and the adjustable seat 21. To ensure a sealing effect, in this embodiment, the first seal 23 blocks the gap between the wall of the shaft through-hole 215 and the lock shaft 12, and also blocks the gap between the adjustable seat 21 and the fixed seat 22. In other embodiments, the first seal 23 may block only the gap between the shaft through-hole 215 and the lock shaft 12, or only the gap between the adjustable seat 21 and the fixed seat 22.

[0078] In order to better achieve the fixation of the first seal 23 relative to the adjusting seat 21, one of the first seal 23 and the adjusting seat 21 is provided with a plug-in convex ring 233, and the other is provided with a plug-in groove 218. The plug-in convex ring 233 is inserted into the plug-in groove 218 with interference fit. Therefore, through the cooperation of the plug-in convex ring 233 and the plug-in groove 218, the installation positioning and limiting of the first seal 23 on the adjusting seat 21 are achieved, ensuring that the sliding of the adjusting seat 21 relative to the fixed seat 22 drives the first seal 23 to move synchronously, thereby ensuring the sealing effect.

[0079] In this embodiment, the first sealing member 23 is provided with a mounting protrusion 233, and the adjustment seat 21 is provided with a mounting groove 218. In other embodiments, the first sealing member 23 may be provided with a mounting groove 218, and the adjustment seat 21 may be provided with a mounting protrusion 233. Specifically, a rib 217 is provided on the underside of the main plate portion 211. The rib 217 and the lower boss portion 216a together form the mounting groove 218.

[0080] Furthermore, on a horizontal projection plane, the orthographic projection of the avoidance shaft hole 2211 is always located inside the outer contour of the orthographic projection of the first sealing member 23. Therefore, when the adjusting seat 21 slides relative to the fixing seat 22, the first sealing member 23 is always partially sandwiched between the adjusting seat 21 and the fixing seat 22 to seal the gap between the adjusting seat 21 and the fixing seat 22, thereby ensuring a reliable seal.

[0081] The first seal 23 includes a sliding seal portion 231 and a shaft seal portion 232 disposed inside the sliding seal portion 231. The sliding seal portion 231 engages with the fixed seat 22 in a sliding and sealing manner, while the shaft seal portion 232 wraps around the lock shaft 12. Specifically, the sliding seal portion 231 is sandwiched between the fixed seat 22 and the adjustable seat 21, and the aforementioned insertion protrusion ring 233 is protruded from the side of the sliding seal portion 231 facing away from the fixed seat 22.

[0082] The thickness of the shaft sealing portion 232 gradually decreases in the direction away from the sliding sealing portion 231, so as to ensure that the overall thickness of the first seal 23 meets the structural strength of the first seal 23 while enhancing the deformation ability of the inner end of the shaft sealing portion 232. Therefore, while the shaft sealing portion 232 wraps the lock shaft 12, the friction between the two is reduced, thereby avoiding the setting of the shaft sealing portion 232 interfering with the rotation of the lock shaft 12.

[0083] In this embodiment, the sliding seal portion 231 is annular, meaning that the entire first seal 23 is annular. In other embodiments, the length of the first seal 23 in the front-to-back direction is greater than its width in the left-to-right direction. This ensures the sealing effect of the first seal 23 while reducing its left-to-right dimension and reducing costs.

[0084] Furthermore, the adjustment assembly 2 also includes a second seal 24, which is sandwiched between the fixing seat 22 and the lower side plate 8011 to seal the gap between the fixing seat 22 and the lower side plate 8011, thereby further preventing airflow from entering the top space through the gap and improving the blocking effect of the adjustment assembly 2. Specifically, the second seal 24 is sandwiched between the lower side plate 8011 and the fixing seat 22.

[0085] In other embodiments, the adjustment assembly 2 may not include the second sealing member 24, and the tight fit between the fixing seat 22 and the lower side surface can be used to prevent the airflow from passing through the fitting gap between the two.

[0086] To better ensure the installation stability of the second seal 24, one of the fixing seat 22 and the second seal 24 is provided with a convex positioning ring portion 242, and the other is provided with a positioning groove 2212. The convex positioning ring portion 242 is inserted into the positioning groove 2212 to achieve the installation and positioning of the second seal 24 on the fixing seat 22, thereby ensuring the reliability of the installation position of the second seal 24 and the fixing seat 22. In this embodiment, the second seal 24 is provided with a convex positioning ring portion 242, and the fixing seat 22 is provided with a positioning groove 2212.

[0087] That is, the second sealing member 24 includes an annular sealing main portion 241 , which is sandwiched between the bottom structure and the fixing seat 22 , and a positioning protruding ring portion 242 is protruded from a side of the sealing main portion 241 away from the bottom structure.

[0088] Example 2

[0089] This embodiment provides an electrical appliance, and the electrical appliance provided in this embodiment is basically the same as that in the second embodiment, with only the arrangement of the adjustment seat 21 and the first sealing member 23 being different. This embodiment will not repeat the same structure as that in the second embodiment.

[0090] like Figures 11 to 13 As shown, the adjustment base 21 includes a main base body and a fixing portion 214 protruding from the upper side of the main base body. The main base body is provided with a shaft through-hole 215. A pressure plate 25 is detachably provided on the upper end of the fixing portion 214. The second end of the lock shaft 12 passes through the pressure plate 25, and the connecting member 13 is constrained between the pressure plate 25 and the main base body. This prevents the connecting member 13 from moving upward, improving the stability of the door lock 1.

[0091] The main seat body includes a main plate portion 211, and the left and right sides of the main plate portion 211 are recessed downward to form recessed portions 212. The two recessed portions 212 are used to connect to the fixed seat 22. In this embodiment, the main plate portion 211 is arranged in a T-shape, that is, the main plate portion 211 includes a front plate portion and a rear plate portion connected front and back. The width of the front plate portion in the left and right directions is greater than the width of the rear plate portion in the left and right directions, so as to increase the sliding fitting surface between the adjustment seat 21 and the fixed seat 22 and ensure the sliding stability of the adjustment seat 21. Recessed portions 212 are provided on the left and right sides of the front plate portion, and an axis through-hole 215 and a fixing portion 214 are provided on the front plate portion, and the rear plate is provided opposite to the rear side of the axis through-hole 215. A fixing portion 214 is provided on each side of the axis through-hole 215, and each fixing portion 214 is located between the axis through-hole 215 and a recessed portion 212.

[0092] In this embodiment, the adjusting fasteners 26 are not only provided on the left and right sides of the front plate, but the rear plate and the fixing seat 22 are also connected by the adjusting fasteners 26 to better ensure the stability of the adjusting seat 21 after adjustment.

[0093] A boss portion 216 is provided on the side of the adjusting seat 21 facing the fixed seat 22. The boss portion 216 is slidably inserted into the shaft through-hole 215, and the lock shaft 12 rotates through the boss portion 216. That is, in this embodiment, the sliding fit between the boss portion 216 and the shaft through-hole 215 provides a guide for the sliding movement of the adjusting seat 21 relative to the fixed seat 22. This increases the vertical length of the sliding fit between the two, reduces the probability of the adjusting seat 21 falling out of the fixed seat 22, and better ensures the sliding reliability and stability of the adjusting seat 21.

[0094] The first seal 23 is sleeved on the outside of the boss portion 216 and is located between the adjustment seat 21 and the fixed seat 22. The adjustment seat 21 and the fixed seat 22 are slidably and sealed together by the first seal 23. That is, in this embodiment, the first seal 23 does not contact the lock shaft 12, and the first seal 23 blocks the gap between the adjustment seat 21 and the fixed seat 22.

[0095] Furthermore, the first seal 23 is interference-fitted on the boss portion 216 , thereby preventing the airflow at the shaft through-hole 215 from entering between the first seal 23 and the boss portion 216 , thereby ensuring the stopping and sealing effect of the first seal 23 and improving the setting stability of the first seal 23 .

[0096] The main seat body further includes a protruding annular rib 217 extending toward the fixed seat 22. The annular rib 217 and the protruding column 216 form a receiving groove 218. The first seal 23 includes a sliding seal portion 231 and a receiving protruding ring 233 protruding from one side of the sliding seal portion 231. The receiving protruding ring 233 is inserted into the sealing groove, and the sliding seal portion 231 is sandwiched between the fixed seat 22 and the annular rib 217.

[0097] Furthermore, the first seal 23 also includes an outer ring portion 234 connected to the outside of the sliding seal portion 231. The outer ring portion 234 is spaced apart from the insert convex ring 233 and is sleeved on the outside of the annular rib portion 217 to enhance the overall structural strength of the first seal 23.

[0098] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
