Description

Technical Field

[0001] This utility model relates to dishwashers, and more specifically, to a dishwasher capable of automatically opening its door. Background Technology

[0002] Currently, many dishwashers use a manual door opening mechanism, requiring the operator to manually trigger the door opening button to unlock the door. A spring-loaded pin positioned between the door and the dishwasher body then uses its elasticity to push the door open, thus completing the opening process. This type of door opening structure is commonly used in countertop double-door dishwashers. For example, Chinese utility model patent CN 217310186U discloses a dishwasher with this door opening structure.

[0003] However, in the above solution, the dishwasher door can only be opened by manual pressing. In some scenarios, pressing may not be possible, making it inconvenient to operate. In particular, since the door opening mechanism requires manual pressing to trigger, it cannot achieve electronic automatic door opening, which has certain limitations.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dishwasher that can open its door automatically.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dishwasher capable of automatically opening its door includes a cabinet and a first door. The first door is rotatably connected to the cabinet via a first hinge. A first limiting part is installed on the side of the first door facing the cabinet. The cabinet is rotatably connected to a first positioning part. When the first door is closed, the position of the first limiting part is opposite to the first positioning part, and the first positioning part can lock the first positioning part.

[0008] The upper part of the housing is rotatably connected to a linkage shaft, and the end of the linkage shaft is fixedly connected to a linkage block. The linkage block and the first positioning part are connected by a transmission mechanism. An unlocking trigger part is fixedly connected to the outside of the linkage shaft. An opening device is installed on the upper part of the housing. The opening device includes a movable drive part, which is used to drive the unlocking trigger part to deflect.

[0009] The present invention is further configured such that the first limiting part has an upward hook and the first positioning part has a downward hook, and the hooks of the first limiting part and the first positioning part can lock each other; the first positioning part can be tilted upward to unlock itself from the first limiting part.

[0010] The present invention is further configured such that the door opening device includes a support frame, a slider and a driver, the slider is slidably connected to the support frame, the driver is installed on the support frame and is used to drive the slider to slide, and a driving part is fixedly connected to the outside of the slider.

[0011] The present invention is further configured such that the driver has a telescopic part, the telescopic part is connected to the slider, and the telescopic direction of the telescopic part is consistent with the sliding direction of the slider.

[0012] The present invention is further configured such that the sliding direction of the slider is set along the front-to-back direction of the dishwasher.

[0013] The present invention is further configured such that a transmission slider is rotatably connected to the upper part of the housing, the transmission slider being located above the unlocking trigger part; an inclined guide part is formed on the side of the transmission slider facing away from the linkage shaft, and the upper side of the inclined guide part is inclined upward toward the linkage shaft.

[0014] The present invention is further configured such that the driving part abuts against the upper side of the inclined guide part, the driver drives the driving part to slide, which can push the transmission slider downward, and the transmission slider can push the unlocking trigger part downward.

[0015] The present invention is further configured such that a torsion spring is installed at the axis of the transmission slider, and the torsion spring is used to drive the transmission slider to elastically reset upward.

[0016] The present invention is further configured such that the upper side of the transmission mechanism is connected to the linkage block, and the lower side of the transmission mechanism is connected to the first positioning part; the unlocking trigger part and the linkage block are respectively located on both sides of the linkage shaft; when the unlocking trigger part deflects downward, the linkage block deflects upward, which can drive the first positioning part to deflect upward.

[0017] The present invention is further configured such that the transmission mechanism includes an upper transmission rod, a transmission block, and a lower transmission rod. The transmission block is slidably connected to the outside of the housing. The upper and lower ends of the upper transmission rod are rotatably connected to the linkage block and the transmission block, respectively. The upper and lower ends of the lower transmission rod are rotatably connected to the transmission block and the first positioning part, respectively.

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

[0019] By incorporating an opening mechanism that works in conjunction with the linkage shaft and unlocking trigger on the upper part of the dishwasher, the opening mechanism pushes down the unlocking trigger during its extension / retraction movement. This causes the linkage shaft to rotate, and the linkage block to deflect upwards. The linkage block then interacts with the first positioning part, causing the first positioning part to deflect upwards and unlock against the first limiting part. This opening mechanism enables the unlocking of the first door, thus achieving automatic door opening. Attached Figure Description

[0026] 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.

[0027] This embodiment discloses a dishwasher capable of automatically opening its door, referring to... Figures 1-5 As shown, it includes a box body 1, a first door 2 and a second door 9. The first door 2 is rotatably connected to the box body 1 via a first hinge 10, and the second door 9 is rotatably connected to the box body 1 via a second hinge 11.

[0028] The first door 2 and the second door 9 are rotatably connected to the housing 1, and together they control the opening and closing of the housing 1. The second door 9 is located above the first door 2. When the first door 2 and the second door 9 are open, they are stacked one on top of the other, and the opening of the housing 1 is open. When the first door 2 and the second door 9 are closed, they together cover and seal the opening of the housing 1.

[0029] Reference Figure 1 As shown, a first limiting part 21 is installed on the side of the first door 2 facing the box 1, and a first positioning part 3 is rotatably connected to the box 1. When the first door 2 is closed, the position of the first limiting part 21 is opposite to the first positioning part 3, and the first positioning part 3 can lock the first positioning part 3.

[0030] The first limiting part 21 has an upward-facing hook, and the first positioning part 3 has a downward-facing hook. When the first positioning part 3 tilts downward, the hooks of the first limiting part 21 and the first positioning part 3 can lock each other. When the first positioning part 3 tilts upward, it can unlock itself from the first limiting part 21.

[0031] Reference Figure 1 , Figure 2 As shown, a linkage shaft 5 is rotatably connected to the upper part of the housing 1, and a linkage block 6 is fixedly connected to the end of the linkage shaft 5. The linkage block 6 and the first positioning part 3 are connected by a transmission mechanism 4, and an unlocking trigger part 51 is fixedly connected to the outer side of the linkage shaft 5. By operating the unlocking trigger part 51, the linkage shaft 5 can be rotated, which causes the linkage block 6 to deflect. The linkage block 6 and the first positioning part 3 can be linked together, causing the first positioning part 3 to deflect upward and unlock the first limiting part 21.

[0032] A torsion spring is installed at the center of the linkage shaft 5. The torsion spring can drive the linkage shaft 5 and the unlocking trigger part 51 to elastically deflect upward to achieve reset.

[0033] Reference Figures 3-5 As shown, an opening device 7 is installed on the upper part of the housing 1. The opening device 7 includes a movable drive unit 74, which is used to drive the unlocking trigger unit 51 to deflect. Specifically, the opening device 7 includes a support frame 71, a slider 72, and a driver 73. The support frame 71 is fixedly installed on the upper side of the housing 1, and the slider 72 is slidably connected to the support frame 71. The driver 73 is installed on the support frame 71 and is used to drive the slider 72 to slide. The drive unit 74 is fixedly connected to the outer side of the slider 72, so that under the driving action of the driver 73, the slider 72 and the drive unit 74 can slide. The drive unit 74 presses the unlocking trigger unit 51 downward, thereby realizing the unlocking action.

[0034] The actuator 73 can specifically be a telescopic wax motor. The actuator 73 has a telescopic part 75, which is capable of telescopic movement. The telescopic part 75 is connected to the slider 72, and the telescopic direction of the telescopic part 75 is consistent with the sliding direction of the slider 72; the actuator 73 can drive both the slider 72 and the drive unit 74. Specifically, the sliding direction of the slider 72 is set along the front-to-back direction of the dishwasher.

[0035] A transmission slider 8 is rotatably connected to the upper part of the housing 1. A rotating shaft 81 is fixedly connected to the axis of the transmission slider 8, and the rotating shaft 81 is rotatably connected to the upper part of the housing 1. A torsion spring is installed at the axis of the transmission slider 8, and the torsion spring can drive the transmission slider 8 to elastically return to its original position.

[0036] The transmission slider 8 is located above the unlocking trigger part 51. An inclined guide part 82 is formed on the side of the transmission slider 8 facing away from the linkage shaft 5, and the upper side of the inclined guide part 82 tilts upwards towards the linkage shaft 5. The drive part 74 abuts against the upper side of the inclined guide part 82. When the telescopic part 75 of the drive 73 extends, it can drive the slider 72 and the drive part 74 to push towards the rear of the dishwasher. During the pushing process, the lower side of the drive part 74 abuts against the inclined guide part 82 of the transmission slider 8. As the telescopic part 75 gradually extends outwards, the drive part 74 will gradually press down the inclined guide part 82 of the transmission slider 8, and the lower side of the transmission slider 8 will abut against the unlocking trigger part 51, causing the unlocking trigger part 51 to deflect downwards. The unlocking trigger part 51 will generate a simulated manual pressing operation, enabling the unlocking operation of the dishwasher door.

[0037] In addition, a protruding structure is fixedly connected to the lower side of the drive unit 74. The protruding structure is adapted to the tilt guide of the tilt guide unit 82, and the two can achieve smooth pressure linkage.

[0038] Reference Figure 1 , Figure 2 As shown, the upper side of the transmission mechanism 4 is connected to the linkage block 6, and the lower side of the transmission mechanism 4 is connected to the first positioning part 3. The unlocking trigger part 51 and the linkage block 6 are located on both sides of the linkage shaft 5, respectively. When the unlocking trigger part 51 deflects downward, the linkage block 6 deflects upward, which can drive the first positioning part 3 to deflect upward, thereby enabling the unlocking operation of the first door body 2.

[0039] Reference Figure 1 , Figure 2 As shown, the first hinge 10 and the second hinge 11 are linked together by the linkage mechanism 12, thereby enabling the first hinge 10 and the second hinge 11, i.e. the first door body 2 and the second door body 9, to achieve synchronous opening and closing actions.

[0040] In addition, a second limiting part and a second positioning part are installed between the second door 9 and the housing 1. The second limiting part and the second positioning part can also be mutually adapted to open and close, enabling the second door 9 to be closed. Specifically, the second limiting part and the second positioning part can adopt a magnetic adsorption structure, allowing the second door 9 to be closed through magnetic adsorption. Alternatively, refer to... Figure 1 , Figure 2 As shown, the second limiting part and the second positioning part can also be locked using a mechanical hook structure.

[0041] Reference Figure 1 , 2 As shown, the transmission mechanism 4 includes an upper transmission rod 41, a transmission block 42, and a lower transmission rod 43. The transmission block 42 is slidably connected to the outside of the housing 1. The upper and lower ends of the upper transmission rod 41 are rotatably connected to the linkage block 6 and the transmission block 42, respectively. The upper and lower ends of the lower transmission rod 43 are rotatably connected to the transmission block 42 and the first positioning part 3, respectively. Alternatively, the transmission mechanism 4 can also use a single transmission rod, which is directly rotatably connected to the linkage block 6 and the first positioning part 3, which can also achieve unlocking linkage.
