Description

Technical Field

[0001] This utility model relates to dishwashers, and more specifically, to a door opening and locking mechanism for a countertop dishwasher. Background Technology

[0002] Current dishwashers typically use a pull-type door opening mechanism. To close the door, a rotation closes it, locking it to the dishwasher's interior. To open it, pulling the door outwards automatically releases the locking mechanism. However, this method, which only locks the door, makes it prone to accidental opening, especially during the high-temperature washing process inside, posing a risk of burns.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a door opening and locking mechanism for a countertop dishwasher.

The mechanism also includes a locking component one, a locking component two, a transmission rod, a transmission shaft, a transmission block, and a pressing block. The locking component one is installed on the side of the first door facing the cabinet, and the locking component two is rotatably connected to the cabinet. When the first door is in the closed position, the locking component two can lock with the locking component one.

[0007] The transmission rod is rotatably connected to the upper part of the housing, and a transmission block is fixedly connected to the end of the transmission rod. The upper and lower ends of the transmission rod are rotatably connected to the transmission block and the locking component, respectively. The pressing block is fixedly connected to the outer periphery of the transmission shaft.

[0008] It also includes a trigger switch and a trigger element. The trigger element includes a rotating connecting part, a first extension part and a second extension part. The rotating connecting part is rotatably connected to the outside of the box body. The first extension part is fixedly connected to the lower side of the rotating connecting part. The second extension part is fixedly connected to the upper side of the rotating connecting part. The first extension part and the trigger switch are adapted to each other. When the first door body is in the closed position, the second locking member can abut against the second extension part, thereby driving the first extension part to trigger the trigger switch.

[0009] The present invention is further configured such that a fixed shaft is fixedly connected to the outer side of the housing, the rotating connecting part is rotatably sleeved on the outside of the fixed shaft, and the trigger switch is located on the lower side of the rotating connecting part.

[0010] The present invention is further configured to include a stop block, which is fixedly connected to the outside of the housing, and the gap formed between the stop block and the outer wall of the housing, wherein the trigger switch and the trigger element are located within the gap.

[0011] The present invention is further configured such that the stop block abuts against the end of the fixed shaft to block and limit the rotational connection.

[0012] The present invention is further configured such that the locking member one has an upward-facing first locking hook; the first end of the locking member two is a rotatable connecting end, which is rotatably connected to the housing, and the second end of the locking member two is fixedly connected to a downward-facing second locking hook; the first locking hook and the second locking hook are mutually locked and adapted.

[0013] The present invention is further configured such that the transmission block and the pressing block are located on both sides of the axial direction of the transmission shaft, the transmission block extends downward at an angle from the outside of the transmission shaft, and the pressing block extends upward at an angle from the outside of the transmission shaft.

[0014] The present invention is further configured such that the upper end of the transmission rod is rotatably connected to the transmission block, and the rotation axis is parallel to the transmission shaft; the lower end of the transmission rod is rotatably connected to the middle of the upper part of the locking member two.

[0015] The present invention is further configured such that a limiting block is fixedly connected to the outside of the box body, the limiting block is located below the second locking member, and is used to block and limit the second locking member; a torsion spring is installed at the rotatable connection between the second locking member and the box body, and the torsion spring is used to elastically drive the second locking member to deflect downward.

[0016] The present invention is further configured such that an outward flange is fixedly connected to the outer side of the opening of the box body, and the outward flange has a notch for a locking member to pass through.

[0017] The present invention is further configured to include a second door, a second hinge, and a linkage mechanism. The second door is rotatably connected to the box body via the second hinge. The second door is located on the upper side of the first door. The first hinge and the second hinge rotate in linkage through the linkage mechanism. The second door and the box body are magnetically attracted to each other.

[0018] In summary, this utility model has the following beneficial effects:

[0019] By employing mutually compatible locking components one and two, which are mutually locked and compatible, the two can lock and cooperate with each other. When the first door is in the closed position, locking component one approaches locking component two, and locking component two can lock with locking component one, thus achieving the closing and locking of the dishwasher door.

[0020] The hooks of locking component one and locking component two can hook and lock each other to ensure that the door is stably closed. When opening, the pressing block needs to be pressed to unlock and open the door, which can prevent the door from opening accidentally.

[0021] A trigger switch and trigger element are also installed on the outside of the cabinet. When the door is closed, the locking element can abut against the trigger element, causing the trigger element to deflect, which can trigger the trigger switch, and then trigger the door closing signal.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This embodiment discloses a door opening and locking mechanism for a countertop dishwasher, referring to... Figures 1-4As shown, the enclosure includes a housing 1, a first door 31, a first hinge 10, a second door 32, a second hinge 11, and a linkage mechanism 12. The second door 32 is located above the first door 31. The first door 31 is rotatably connected to the first hinge 10, and the second door 32 is rotatably connected to the housing 1 via the second hinge 11. The first door 31 and the second door 32 can be combined by rotating together, enabling the opening and closing of the housing 1.

[0029] The first hinge 10 and the second hinge 11 rotate in tandem via a linkage mechanism 12. Through the linkage of the linkage mechanism 12, the first door 31 and the second door 32 can open and close simultaneously. When closed, the first door 31 and the second door 32 together cover and close the opening of the box 1; when opened, the first door 31 and the second door 32 deflect downwards and stack on top of each other.

[0030] The dishwasher in this embodiment also includes a first locking member 4, a second locking member 5, a transmission rod 6, a transmission shaft 7, a transmission block 8, and a pressing block 9. The first locking member 4 is fixedly installed on the side of the first door 31 facing the cabinet 1, and the second locking member 5 is rotatably connected to the cabinet 1; the installation positions of the two are mutually compatible. When the first door 31 is in the closed position, the first locking member 4 is close to the second locking member 5, and the second locking member 5 can lock with the first locking member 4, thus achieving the closing and locking of the dishwasher.

[0031] The transmission rod 6 is rotatably connected to the upper part of the housing 1. A transmission block 8 is fixedly connected to the end of the transmission rod 6. The upper and lower ends of the transmission rod 6 are rotatably connected to the transmission block 8 and the second locking element 5, respectively. A pressing block 9 is fixedly connected to the outer periphery of the transmission shaft 7. By pressing the pressing block 9, the transmission shaft 7 can be rotated, and the transmission block 8 will deflect accordingly. The transmission rod 6 can create a linkage between the transmission block 8 and the second locking element 5, causing the second locking element 5 to deflect, thereby enabling the first locking element 4 and the second locking element 5 to unlock each other.

[0032] In this embodiment, a trigger switch 2 and a trigger element 21 are also installed on the outside of the housing 1. The trigger element 21 includes a rotating connecting part 211, a first extension part 212, and a second extension part 213. The rotating connecting part 211 is rotatably connected to the outside of the housing 1. The first extension part 212 is fixedly connected to the lower side of the rotating connecting part 211, and the second extension part 213 is fixedly connected to the upper side of the rotating connecting part 211. The first extension part 212 is adapted to the trigger switch 2.

[0033] The second extension 213 of the trigger member 21 is positioned opposite the height of the locking member 4. When the first door 31 is in the closed position, the locking member 5 can abut against the second extension 213, causing the first extension 212 to trigger the trigger switch 2. The trigger switch 2 can be a micro switch, and the first extension 212 presses against the button of the micro switch.

[0034] A fixed shaft 105 is fixedly connected to the outside of the housing 1, and a rotating connecting part 211 is rotatably sleeved on the outside of the fixed shaft 105, enabling rotation. A trigger switch 2 is located below the rotating connecting part 211, and the button of the trigger switch 2 is positioned away from the first door 31 and the second door 32.

[0035] A stop block 13 is fixedly connected to the outside of the dishwasher casing 1. The stop block 13 is connected and fixed to the connecting seat 102 on the outside of the casing 1 by screws. The stop block 13 is fixedly connected to the outside of the casing 1, and the trigger switch 2 and the trigger element 21 are located within the gap formed between the stop block 13 and the outer wall of the casing 1. The stop block 13 can block and cover the space between the trigger switch 2 and the trigger element 21, and can play a protective blocking role on the outside.

[0036] The stop 13 abuts against the end of the fixed shaft 105. The stop 13 can form a block at the end of the stop 13, blocking and limiting the rotational connection 211, thereby ensuring that the trigger 21 can be stably limited at the gap position.

[0037] An outward flange 103 is fixedly connected to the outside of the opening of the cabinet 1. The outward flange 103 has a notch 104 for the locking member 4 to pass through. When the first door 31 is closed, it can pass through the notch 104 and extend into the inside of the dishwasher housing, and can press against and link with the second extension 213 of the trigger member 21.

[0038] Reference Figure 2 , Figure 4 As shown, locking component 4 has an upward-facing first locking hook 41. Locking component 5 has a first end that is a rotatable connecting end 51, which is rotatably connected to the housing 1. The second end of locking component 5 is fixedly connected to a downward-facing second locking hook 52. The first locking hook 41 and the second locking hook 52 are mutually locked and adapted. The two hooks interlock, allowing the door to be closed and locked.

[0039] Reference Figure 1 , Figure 3 As shown, the transmission block 8 and the pressing block 9 are located on both sides of the axial direction of the transmission shaft 7. The transmission block 8 extends downwards and outwards from the transmission shaft 7, while the pressing block 9 extends upwards and outwards from the transmission shaft 7. The pressing block 9 extends upwards and outwards towards the door body, while the transmission block 8 extends downwards and outwards towards the direction opposite to the door body.

[0040] Specifically, the upper end of the transmission rod 6 is rotatably connected to the transmission block 8, and its rotation axis is parallel to that of the transmission shaft 7. The lower end of the transmission rod 6 is rotatably connected to the upper middle of the locking member 5. By pressing down on the pressing block 9, the transmission block 8 can be driven to deflect upward, which in turn drives the transmission rod 6 and the locking member 5 to deflect upward.

[0041] A limiting block 101 is fixedly connected to the outside of the housing 1, located below the locking member 5. The limiting block 101 blocks and limits the locking member 5, thus restricting it to a certain angle. A torsion spring is installed at the rotatable connection between the locking member 5 and the housing 1. The torsion spring acts on the locking member 5, causing its second hook 52 to deflect downwards. Inclined guide surfaces are formed on opposite sides of the first hook 41 and the second hook 52. When the first hook 41 and the second hook 52 press against each other, they push the locking member 5 and the second hook 52 upwards. Then, under the action of the spring, the locking member 5 is pushed downwards to elastically deflect and reset, thereby locking the first door 31 and the second hook 52 together.

[0042] In addition, at positions opposite to the second door 32 and the box 1, mutually magnetic components are installed. When the second door 32 is closed, the second door 32 and the box 1 can magnetically attract each other, thus achieving magnetic locking of the second door 32.

[0043] A permanent magnet is installed in the second door 32, and an electromagnet is fixedly installed in the housing 1. The permanent magnet and the electromagnet are magnetically attracted and locked together. When the first door 31 is closed, the locking component 4 triggers the trigger switch 2. The trigger switch 2 is connected, and the electromagnet is energized to generate magnetic attraction, which allows the electromagnet to magnetically attract and lock with the permanent magnet, thereby locking and closing the second door 32.

[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
