In addition, the terms "first", "second" are only used to distinguish in description and have no special meaning.

[0042] As Figures 1 to 4 As shown in the drawings, the embodiment provides a door lock device 100 and an electric appliance comprising the door lock device 100, so as to meet the opening and closing door demand of the electric appliance and the exhaust demand in the use process, improve the use reliability and use experience of the electric appliance.

[0043] Specifically, the electric appliance comprises a body and a door 500 movably mounted on the front side of the body, the body has an inner cavity with an opening on the front side, and the door 500 is capable of rotating relative to the body to open or close the opening of the inner cavity. The top end of the door 500 is provided with a lock shaft 200, and the body is provided with a door lock device 100, which is used to cooperate with the lock shaft 200 to restrict the locking or unlocking of the door 500 relative to the body.

[0044] The door lock device 100 comprises a door lock actuating mechanism 1, a lock seat 3 and a door lock piece 2. The door lock piece 2 comprises a lock hook 21, which is capable of rotating with the first end in the length direction as the axis to swing the second end relative to the first end. The lock hook 21 has a lock groove, which has an access opening 213 between the two ends of the lock hook 21. The groove wall opposite to the access opening 213 is provided with a partition 214, which extends to the access opening 213 and separates the lock groove into a first lock groove 211 and a second lock groove 212 arranged side by side in the length direction, and the first lock groove 211 is arranged close to the first end of the lock groove.

[0045] Specifically, the first end of the lock hook 21 is rotatably mounted on the lock seat 3, and the door lock actuating mechanism 1 drives the door lock piece 2 to rotate from the first position to the second position, or to rotate beyond the second position to the third position. When the door lock piece 2 is in the first position, the second lock groove 212 is arranged side by side with the first lock groove 211 in the front-rear direction, and the second lock groove 212 is located on the front side of the first lock groove 211, and the partition 214 restricts the lock shaft 200 located in the first lock groove 211 from moving forward; when the door lock piece 2 is in the second position, the door lock piece 2 is inclined at a first angle relative to the front-rear direction, so that the lock shaft 200 located in the first lock groove 211 can pass through the partition 214 to the second lock groove 212 and be limited in the second lock groove 212; when the door lock piece 2 is in the third position, the door lock piece 2 is inclined at a second angle relative to the front-rear direction, and the access opening 213 is inclined to be arranged forward, so that the lock shaft 200 can be pulled out of the lock groove forward, and the second angle is greater than the first angle.

[0046] Specifically, when the door lock piece 2 is in the first position (as shown in Figure 4 (a)), the lock hook 21 extends straight from back to front, the access opening 213 of the lock groove faces the left side or the right side, and the lock shaft 200 located in the first lock groove 211 abuts against the back side of the partition 214, so that the partition 214 restricts the lock shaft 200 from moving forward; when the door lock piece 2 is in the second position (as shown in Figure 4(b) shown), the locking hook 21 is deflected by a first angle relative to the front-rear direction, so that the access opening 213 is inclined towards the front, the partition 214 exits the path of the lock shaft 200 moving forward, the lock shaft 200 can be moved from the first lock slot 211 to the second lock slot 212 and abuts against the front slot wall of the second lock slot 212, that is, the machine door 500 can be flipped open by a set angle relative to the machine body and stably maintained in this state, meeting the exhaust demand; after the exhaust is completed, the door lock 2 is rotated from the second position back to the first position, so that the locking hook 21 drives the lock shaft 200 to enter the first lock slot 211 from the second lock slot 212 backwards, so that the machine door 500 returns to the closed door state. When the machine door 500 needs to be opened (for example Figure 4 (a) shown), the locking hook 21 is deflected by a second angle relative to the front-rear direction, the second angle is greater than the first angle, so that the front end of the locking hook 21 and the partition 214 both exit the path of the lock shaft 200 moving forward, and further, the lock shaft 200 in the first lock slot 211 can exit the lock slot forward.

[0047] That is, the door lock 2, the door lock device 100 and the electric appliance provided by the utility model can make the lock shaft 200 be limited in the second lock slot 212 through the partition 214 when the machine door 500 is closed, so that the machine door 500 is stably maintained in the closed state; when the locking hook 21 is rotated and switched to the second position, the lock shaft 200 can move forward to the first lock slot 211 and be limited in the first lock slot 211 by crossing the partition 214, so that on the basis of the locking hook 21 and the lock shaft 200 being maintained in cooperation, the upper end of the machine door 500 can be moved forward by a certain distance relative to the machine body, and further, the machine door 500 can be opened by a preset angle relative to the machine body, meeting the effect of heat dissipation and exhaust in the inner container 300, and at the same time, the cooperation of the lock shaft 200 and the locking hook 21 can avoid the machine door 500 being completely opened, ensuring the stability and reliability of the machine door 500 when being opened by the preset angle; at the same time, through the reset of the locking hook 21 from the second position to the first position, the lock shaft 200 can be returned from the second lock slot 212 to the first lock slot 211, and further, the machine door 500 can be closed relative to the machine body, so that the automatic closing of the machine door 500 after being opened by the preset angle can be realized, the automaticity of the opening and closing control of the electric appliance is improved, and the tightness of the machine door 500 when being closed can be ensured, and the use reliability and use experience of the electric appliance are improved.

[0048] In the embodiment, the lower end of the machine door 500 is rotatably installed on the front side of the machine body by a hinge mechanism, and the hinge mechanism applies an elastic force to the machine door 500 to make the machine door 500 move away from the machine body when the machine door 500 is closed relative to the machine body or the opening angle of the machine door 500 relative to the machine body is less than or equal to a preset angle. Thus, when the machine door 500 is in the closed state and the door lock member 2 is moved from the first position to the second position, the machine door 500 can be automatically flipped forward under the action of the hinge mechanism, thereby driving the lock shaft 200 to move from the first lock groove 211 to the second lock groove 212; when the door lock member 2 is moved to the third position, the machine door 500 can be flipped forward under the force applied by the hinge mechanism, so that the lock shaft 200 is out of the cooperation range of the lock hook 21, and the machine door 500 is flipped open.

[0049] It is worth noting that when the machine door 500 is flipped relative to the machine door 500 by an angle greater than a certain angle, the hinge mechanism applies a force to the machine door 500 to hinder the machine door 500 from being flipped downward, so that the machine door 500 is slowly opened. The specific structure of the hinge mechanism can be set according to the prior art, and the embodiment will not be described here.

[0050] It is worth noting that when the door lock member 2 is in the second position to exhaust, after the exhaust is completed, the door lock actuating mechanism 1 can directly drive the door lock member 2 to rotate from the second position to the third position, so that the lock shaft 200 located in the second lock groove 212 is directly moved forward to escape from the second lock groove 212, and the machine door 500 is opened relative to the machine door 500.

[0051] In the embodiment, the door lock device 100 further comprises a door lock reset member 5, which promotes the door lock member 2 to remain or return to the first position. That is, after the driving force applied by the door lock actuating mechanism 1 to the door lock member 2 is removed, the door lock member 2 is automatically reset to the first position under the action of the door lock reset member 5, which reduces the driving difficulty of the door lock actuating mechanism 1, simplifies the control, and can meet the needs of users to manually close the door, thereby improving the use experience of the electric appliance.

[0052] The second end of the lock hook 21 has a guide surface 215 extending obliquely to the access opening 213 in a direction towards the first end of the lock hook 21. That is, when the door lock member 2 is in the first position, the guide surface 215 extends obliquely from front to back to the access opening 213. When the machine door 500 is opened, the door lock member 2 is in the first position under the action of the door lock reset member 5; during the closing process of the machine door 500, the lock shaft 200 first contacts the guide surface 215, pushes the lock hook 21 to rotate from the first position to the third position, and then the lock shaft 200 can enter the first lock groove 211 backward; and after the lock shaft 200 enters the first lock groove 211, the door lock member 2 returns to the first position under the action of the door lock reset member 5, thereby ensuring that the machine door 500 is in a stable closed state through the stable cooperation of the door lock member 2 and the lock shaft 200.

[0053] The second lock slot 212 is connected with the guide surface 215 by a circular arc, which is beneficial to guide the lock shaft 200 to enter the second lock slot 212 along the guide surface 215, reduce the friction between the lock hook 21 and the lock shaft 200, and improve the smoothness of the manual door closing.

[0054] In order to guide the lock shaft 200 in the second lock slot 212 to enter the first lock slot 211, in the embodiment, the partition 214 extends in a direction close to the first end of the lock hook 21 along the direction of the access opening 213, so that when the lock shaft 200 is in the second lock slot 212, the lock shaft 200 moves relative to the slot wall of the second lock slot 212 and enters the first lock slot 211 under the guidance of the partition 214, ensuring the smoothness of the door 500 after the exhaust. Further, the included angle between the extension direction of the partition 214 and the extension direction of the lock hook 21 is 35°-65°.

[0055] In an embodiment, the maximum width of the lock slot in the width direction of the lock hook 21 is D, the width of the partition 214 in the width direction of the lock hook 21 is d, and 0.3D

[0056] The thickness of the partition 214 in the length direction of the lock hook 21 gradually decreases in the direction of the access opening 213, thereby ensuring the connection stability and reliability between the partition 214 and the main structure of the lock hook 21, avoiding the problem of tearing of the root of the partition 214 under the extrusion of the lock shaft 200, and improving the use safety and reliability of the lock hook 21; at the same time, the width of the partition 214 gradually decreases in the direction of the access opening 213, which can increase the deformation ability of the end of the partition 214, so that the partition 214 can better guide the lock shaft 200 in the second lock slot 212 to enter the first lock slot 211 during the manual closing of the door 500.

[0057] Further, the end of the partition 214 close to the access opening 213 is a circular arc structure, which is smoothly connected with the opposite sides of the partition 214, thereby avoiding scratching the lock shaft 200 when the lock shaft 200 enters and exits the first lock slot 211, improving the smoothness of the lock shaft 200 entering the first lock slot 211, and also reducing the wear of the partition 214 by the door lock 2.

[0058] To improve the stop effect of the first lock groove 211 on the lock shaft 200 when the door lock piece 2 is in the first position, in the embodiment, the side of the separation part 214 away from the second lock groove 212 is connected to the adjacent groove wall of the first lock groove 211 in a circular arc transition, so that the groove bottom of the first lock groove 211 is in a circular arc structure, so that the shape of the groove bottom of the first lock groove 211 is adapted to the shape of the lock shaft 200, and the lock shaft 200 is beneficially clamped on the groove bottom of the first lock groove 211.

[0059] Further, the groove wall of the first lock groove 211 corresponding to the access opening 213 is arranged along the length direction of the lock hook 21 and is connected in a smooth transition with the circular arc surface. When the door lock piece 2 is in the first position, the groove wall abuts against the lock shaft 200, that is, when the lock shaft 200 is limited in the first lock groove 211, the two adjacent groove walls of the first lock groove 211 abut against the lock shaft 200, so as to better ensure the setting stability of the lock shaft 200 in the first lock groove 211.

[0060] In the embodiment, the groove wall of the first lock groove 211 opposite to the separation part 214 is perpendicular to the length direction of the lock hook 21, so as to simplify the structure of the lock hook 21 and reduce the processing difficulty of the lock hook 21.

[0061] Further, the second lock groove 212 is a U-shaped groove, the U-shaped groove has a groove bottom to a groove opening, which is arranged to be inclined to the access opening 213 in the direction close to the first end of the lock hook 21, and the bottom of the U-shaped groove is in a circular arc structure, and the groove wall of the U-shaped groove is arranged in a smooth transition. That is, when the door lock piece 2 is in the first position, the groove opening of the U-shaped groove is arranged to be inclined backward. The arrangement of the U-shaped groove can guide the lock shaft 200 in the second lock groove 212 to enter the first lock groove 211 when the door lock piece 2 is rotated from the second position to the first position, and is beneficial to limit the lock shaft 200 from escaping from the second lock groove 212 when the door lock piece 2 is in the second position, so as to ensure the limiting reliability of the second lock groove 212 on the lock shaft 200.

[0062] In the embodiment, the door lock piece 2 further comprises a lock rotating shaft 22, which is fixedly connected to the first end of the lock hook 21 and perpendicular to the lock hook 21. The lock rotating shaft 22 is rotatably installed on the lock seat 3, and the rotation axis of the lock rotating shaft 22 is the rotation axis of the lock hook 21. The arrangement of the lock rotating shaft 22 is beneficial to the installation of the door lock piece 2.

[0063] In the embodiment, the lock rotating shaft 22 has a certain length, the first end of the lock hook 21 is provided with a shaft connecting hole 216, and the first end of the lock rotating shaft 22 is inserted into the shaft connecting hole 216. The cross section of the first end of the lock rotating shaft 22 is a non-circular cross section, and the shape of the shaft connecting hole 216 is adapted to the shape of the first end of the lock rotating shaft 22, so as to avoid relative rotation between the lock rotating shaft 22 and the lock hook 21, and ensure the synchronization of the rotation of the lock rotating shaft 22 and the lock hook 21. In other embodiments, the lock rotating shaft 22 and the lock hook 21 can be integrally formed or welded.

[0064] In the embodiment, the machine body comprises an inner container 300 with an open front side and a cabinet 400 surrounding the outer side of the inner container 300, the cabinet 400 comprises a front frame 402 surrounding the front side of the inner container 300, a top support plate 403 mounted above the inner container 300 and connected to the front frame 402 at the front end, and a cabinet shell 401 surrounding the outer side of the front frame 402 and the top support plate 403. The machine body further comprises a control panel 600 mounted on the top front side of the front frame 402 through a panel support 601. The control panel 600, the top support plate 403 and the cabinet shell 401 surround a top cavity. The control panel 600 protrudes forward of the front side of the inner container 300.

[0065] The door lock actuating mechanism 1 and the lock seat 3 are installed in the top cavity, and the lock hook 21 at least passes through the panel support 601 out of the top cavity and is located on the lower side of the control panel 600 to cooperate with the lock shaft 200.
