[0001] This application relates to the field of dishwasher technology, and in particular to a door status detection device and a dishwasher. Background Technology

[0002] The opening and closing status of the dishwasher door needs to be detected by a microswitch. Generally, when the user closes the door, a certain amount of force is applied.

[0003] This application aims to at least partially solve one of the technical problems in the related art. To this end, this application proposes a gate state detection device.

[0004] To achieve the above objectives, this application discloses a door state detection device, the door state detection device comprising:

[0007] In some embodiments of this application, at least one of the first arm and the second arm is U-shaped.

[0008] In some embodiments of this application, the transmission member further includes a rotating part, the transmission member is adapted to be rotatably configured via the rotating part, the first support arm is U-shaped, and one end of the first support arm is connected to the rotating part, and the other end is adapted to be pushed by the door body.

[0009] In some embodiments of this application, the second arm is connected to the rotating part, and the maximum distance between the second arm and the rotation axis of the transmission member in the radial direction is greater than the maximum distance between the first arm and the rotation axis of the transmission member. The radial direction passes through the rotation axis of the transmission member and is perpendicular to the rotation axis of the transmission member.

[0010] In some embodiments of this application, the second arm includes a second support section and a second contact section. One end of the second support section is connected to the rotating part, and the second contact section is inclined toward the detection component from the other end of the second support section. The second arm is adapted to touch the contact point through the second contact section.

[0011] In some embodiments of this application, an included angle is formed between the first arm and the second arm, the vertex of the included angle coincides with the rotation axis of the transmission member, and the included angle is an acute angle.

[0012] In some embodiments of this application, the surface of the second arm is provided with a raised portion, and the second arm is adapted to touch the contact point through the raised portion.

[0013] In some embodiments of this application, the transmission member further includes a third arm, which is adapted to elastically deform when the transmission member rotates in the first direction, so as to generate a force on the transmission member that causes the transmission member to rotate in a second direction, which is opposite to the first direction.

[0014] In some embodiments of this application, when the transmission member rotates along the first direction, the third arm first encounters resistance, and then the second arm touches the contact point.

[0015] In some embodiments of this application, the transmission component is a one-piece molded part;

[0016] And / or, the detection component is a micro switch.

[0017] In some embodiments of this application, the door status detection device further includes a housing with an opening, the transmission member being rotatably disposed within the housing, the first support arm protruding from the opening, and the detection component being disposed within the housing.

[0018] In some embodiments of this application, the door status detection device further includes a housing, the housing having a rotating shaft, the rotating part having a shaft hole, and the transmission component being sleeved on the rotating shaft through the shaft hole for rotatable configuration.

[0019] A second aspect of this application discloses a dishwasher, which includes a door and the aforementioned door status detection device.

[0020] In some embodiments of this application, the dishwasher further includes a body, the body having a washing chamber and a first fastener;

[0024] In some embodiments of this application, the door status detection device and the linkage rod are respectively disposed on the machine body, and the transmission component is located between the linkage rod and the detection component.

[0025] The technical solution of this application sets up a transmission component. When the door is closed, the first arm of the transmission component is pushed, causing the transmission component to rotate. The rotation of the transmission component causes the second arm to touch the contact point of the detection component, thereby connecting or disconnecting the circuit and realizing the detection of the door status.

In this way, the impact on the detection component can be reduced at the moment the second arm touches the contact point of the detection component, which helps to extend the service life of the detection component.

If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0044] The first aspect of this application discloses a gate state detection device 1000, combined with... Figures 1 to 8 As shown, the door detection device includes a detection component 1100 and a transmission component 1200. The detection component 1100 includes a contact 1110. The transmission component 1200 is rotatably configured and includes a first arm 1210 and a second arm 1220. The first arm 1210 is adapted to be pushed by the door body 2000 to make the transmission component 1200 rotate in a first direction. The second arm 1220 is adapted to actuate the contact 1110 when the transmission component 1200 rotates in the first direction. At least one of the first arm 1210 and the second arm 1220 is adapted to elastically deform.

[0045] In this embodiment, when the door 2000 is closed, it pushes the first arm 1210 of the transmission member 1200, causing the transmission member 1200 to rotate. The rotation of the transmission member 1200 causes the second arm 1220 to touch the contact point 1110 of the detection member 1100, thereby connecting or disconnecting the circuit and realizing the detection of the state of the door 2000. At least one of the first arm 1210 and the second arm 1220 can be elastically deformed. In this way, the impact on the detection member 1100 can be reduced at the moment when the second arm 1220 touches the contact point 1110 of the detection member 1100, which helps to extend the service life of the detection member 1100.

[0046] The dishwasher door status detection device 1000 will be described in conjunction with the dishwasher. The dishwasher includes a body 3000 and a door 2000. The body 3000 is provided with a washing chamber (not shown in the figure). The door 2000 can move between an open position and a closed position. When the door 2000 moves to the closed position, the washing chamber is closed; when the door 2000 moves to the open position, the washing chamber is open. The washing chamber is used to install a dish rack, which can slide in and out of the washing chamber to facilitate the loading and unloading of tableware. The tableware includes, but is not limited to, washable items such as bowls, plates, cups, pots, knives, forks, and chopsticks.

[0047] In order to detect the status of the door 2000, in this embodiment, a door status detection device 1000 is set up. The door status detection device 1000 includes a detection component 1100 and a transmission component 1200. The detection component 1100 includes a contact 1110. When the contact 1110 is touched (pressed), the corresponding circuit is connected or disconnected (whether it is connected or disconnected depends on the internal structure of the detection component 1100). Correspondingly, when the contact 1110 is reset, the corresponding circuit is disconnected or connected. There are various types of detection components 1100, such as a micro switch. The detection component 1100 needs to cooperate with a rotatably configured transmission component 1200. The transmission component 1200 includes a first arm 1210 and a second arm 1220. At least one of the first arm 1210 and the second arm 1220 is suitable for elastic deformation. It can be that the first arm 1210 is elastically adapted to elastic deformation, or that the second arm 1220 is elastically adapted to elastic deformation, or that both the first arm 1210 and the second arm 1220 can elastically deform. When the door 2000 is closed... When the washing chamber is closed, the door 2000 pushes the first arm 1210. This can be done directly or indirectly, with the closing action of the door 2000 transmitting force to the first arm 1210. This causes the transmission component 1200 to rotate in the first direction, which in turn causes the second arm 1220 to actuate the contact point 1110, connecting or disconnecting the corresponding circuit, thus determining the state of the door 2000. Since at least one of the first arm 1210 and the second arm 1220 can undergo elastic deformation, the impact energy generated at the moment the door 2000 closes is absorbed by the elastically deformed first arm 1210 and / or second arm 1220. This reduces or even prevents the impact from being transmitted to the detection component 1100 and causing damage to the detection component 1100, thus helping to extend the service life of the detection component 1100.

[0048] For example, the transmission component 1200 includes a rotating part 1240, a first support arm 1210 and a second support arm 1220. The first support arm 1210 is fixedly connected to the rotating part 1240, and the second support arm 1220 is fixedly connected to the rotating part 1240. The rotating part 1240 is provided with a shaft hole 1241 or a rotating shaft, and the transmission component 1200 is rotatably connected through the rotating part 1240. The transmission component 1200 can rotate to a first position and a second position. When the door 2000 pushes the first arm 1210, the transmission component 1200 can rotate counterclockwise (in the first direction) from the first position to the second position. When the transmission component 1200 rotates to the second position, the second arm 1220 touches the contact point 1110 (the contact point 1110 is located on the rotation path of the second arm 1220), thus connecting or disconnecting the corresponding circuit to realize the judgment of the state of the door 2000. At least one of the first arm 1210 and the second arm 1220 undergoes elastic deformation to absorb the impact and avoid damage to the detection component 1100.

[0049] Combination Figures 1 to 8 As shown, in some embodiments, at least one of the first arm 1210 and the second arm 1220 is U-shaped. The first arm 1210 may be U-shaped, the second arm 1220 may be U-shaped, or both the first arm 1210 and the second arm 1220 may be U-shaped. With the U-shaped structure, when subjected to force, the two ends of the U-shaped structure will move closer or further apart, which is more conducive to absorbing and buffering the impact energy brought by external forces, effectively reducing the transmission of vibration. Furthermore, the U-shaped structure has better buckling resistance within the elastic deformation range, which helps to improve the stability of the transmission component 1200.

[0050] Taking the first arm 1210 as a U-shape as an example, one end of the first arm 1210 is fixedly connected to the rotating part 1240 of the transmission component 1200, and the other end of the first arm 1210 is suitable to be pushed by the door body 2000. That is, when the door body 2000 is closed, the door body 2000 pushes the other end of the first arm 1210, thereby driving the transmission component 1200 to rotate in the first direction. The two ends of the first arm 1210 approach each other and undergo elastic deformation to absorb the impact.

[0051] Combination Figures 1 to 8 As shown, in some embodiments, the second arm 1220 is fixedly connected to the rotating part 1240 of the transmission member 1200. Along the radial direction, the maximum distance between the second arm 1220 and the rotation axis of the transmission member 1200 is greater than the maximum distance between the first arm 1210 and the rotation axis of the transmission member 1200. The radial direction passes through the rotation axis of the transmission member 1200 and is perpendicular to the rotation axis of the transmission member 1200. The rotation axis of the transmission member 1200 is the rotation axis of the rotating part 1240.

[0052] See Figure 8As shown, measured radially, the maximum distance between the rotation axes of the first arm 1210 and the transmission component 1200 is L1, and the maximum distance between the rotation axes of the second arm 1220 and the transmission component 1200 is L2, satisfying L2 > L1. That is to say, the extension of the second arm 1220 away from the rotation axis of the transmission component 1200 is greater than that of the first arm 1210. Thus, even if the second arm 1220 is not a U-shaped structure, it still has a certain elastic deformation performance. In particular, when the second arm 1220 is not a U-shaped structure, the overall structural arrangement of the transmission component 1200 can be designed to be more compact.

[0053] Optionally, combined Figure 8 As shown, in some embodiments, the second arm 1220 includes a second support section 1221 and a second contact section 1222. The second support section 1221 is fixedly connected to the rotating part 1240. One end of the second support section 1221 is connected to the rotating part 1240. The second contact section 1222 is inclined from the other end of the second support section 1221 toward the detection component 1100 to form a corner space 1224 between the second contact section 1222 and the second support section 1221. The second arm 1220 is adapted to touch the contact point 1110 through the second contact section 1222.

[0054] The second arm 1220 is not straight, but includes a second support section 1221 and a second contact section 1222. The second contact section 1222 is tilted from the second support section 1221, which is equivalent to the intersection of the second support section 1221 and the second contact section 1222. This arrangement takes into account both the elastic deformation and rigidity of the second arm 1220, and also helps to make the structural layout more compact.

[0055] Combination Figure 8 As shown, in some embodiments, an angle is formed between the first arm 1210 and the second arm 1220, the vertex of which coincides with the rotation axis of the transmission member 1200, and the angle is acute. An acute angle between the first arm 1210 and the second arm 1220 means that the first arm 1210 and the second arm 1220 are close to each other, which helps to reduce the space occupied by the transmission member 1200. For example, the angle between the first arm 1210 and the second arm 1220 is α, where α is 15°, 20°, 30°, 40°, 50°, or 60°.

[0056] Given that an angle is formed between the first arm 1210 and the second arm 1220, in order to prevent root fracture when either the first arm 1210 or the second arm 1220 undergoes elastic deformation, combined with... Figure 8As shown, in some embodiments, the transmission member 1200 further includes a reinforcing rib 1250. The first support arm 1210 is fixedly connected to the rotating part 1240 of the transmission member 1200, and the second support arm 1220 is fixedly connected to the rotating part 1240 of the transmission member 1200. The reinforcing rib 1250 is disposed in the rotating part 1240 and between the first support arm 1210 and the second support arm 1220. The side of the reinforcing rib 1250 facing away from the rotating part 1240 is concave arc-shaped. With this arrangement, the reinforcing rib 1250 can effectively support the root of the first support arm 1210 and the root of the second support arm 1220 (the root is the part close to the rotating part 1240) and prevent the root from breaking.

[0057] Combination Figure 8 As shown, the surface of the second arm 1220 is provided with a raised portion 1223, and the second arm 1220 is adapted to touch the contact point 1110 through the raised portion 1223. As can be seen from the above, when the first arm 1210 is pushed by the door body 2000, the entire transmission component 1200 rotates, that is, the second arm 1220 rotates accordingly. The path of the second arm 1200 is arc-shaped. Generally speaking, the contact point 1110 is only slightly raised. This requires the transmission component 1200 and the detection component 1100 to be precisely matched in relative position. Otherwise, the second arm 1220 is prone to abutting against the periphery of the contact point 1110, resulting in poor contact with the contact point 1110. However, with the setting of the raised part 1223, the raised part 1223 is raised relative to its periphery. Even if there is a slight deviation in the relative position of the transmission component 1200 and the detection component 1100, the raised part 1223 can still touch the contact point 1110 to avoid poor contact and reduce the assembly difficulty.

[0058] Combination Figures 1 to 8 As shown, in some embodiments, the transmission member 1200 further includes a third arm 1230, which is adapted to elastically deform when the transmission member 1200 encounters resistance while rotating in a first direction, so as to generate a force on the transmission member 1200 that causes the transmission member 1200 to rotate in a second direction, which is opposite to the first direction.

[0059] When the door 2000 closes the washing chamber, the transmission component 1200 rotates in the first direction, causing the second arm 1220 to touch the contact 1110. When the door 2000 opens the washing chamber, the transmission component 1200 needs to rotate in the second direction to reset, causing the second arm 1220 to leave the contact 1110, thus resetting the contact 1110. In this embodiment, the transmission component 1200 also includes a third arm 1230. When the transmission component 1200 rotates along the first direction, the third arm 1230 encounters resistance and undergoes elastic deformation. This resistance means that the third arm 1230 encounters an obstacle. Thus, the third arm 1230 can undergo elastic deformation to accumulate elastic potential energy, thereby generating a force on the transmission component 1200 that causes the transmission component 1200 to rotate along the second direction. Since the force applied by the door 2000 to the first arm 1210 is greater than the force generated by the elastic deformation of the third arm 1230, the transmission component 1200 can rotate along the first direction until the second arm 1220 touches the contact point 1110. When the door 2000 opens the washing chamber, the force applied by the door 2000 to the first arm 1210 disappears, and the third arm 1230 releases its elastic potential energy, thereby driving the transmission component 1200 to rotate and reset along the second direction, causing the second arm 1220 to leave the contact point 1110, and the contact point 1110 to reset.

[0060] For example, the transmission component 1200 includes a rotating part 1240, a first support arm 1210, a second support arm 1220, and a third support arm 1230. The first support arm 1210 is fixedly connected to the rotating part 1240, the second support arm 1220 is fixedly connected to the rotating part 1240, and the third support arm 1230 is fixedly connected to the rotating part 1240. The rotating part 1240 is provided with a shaft hole 1241 or a rotating shaft. The transmission component 1200 is rotatably connected through the rotating part 1240. The transmission component 1200 can rotate to a first position and a second position. When the door 2000 pushes the first arm 1210, the transmission component 1200 can rotate counterclockwise (in the first direction) from the first position to the second position. When the transmission component 1200 rotates to the second position, the second arm 1220 touches the contact point 1110 (the contact point 1110 is located on the rotation path of the second arm 1220). The third arm 1230 encounters resistance and undergoes elastic deformation, generating a force on the transmission component 1200 that causes the transmission component 1200 to rotate in the second direction. When the door 2000 opens the washing chamber, the force applied to the first arm 1210 by the door 2000 disappears, the third arm 1230 releases its elastic potential energy, causing the transmission component 1200 to rotate clockwise (in the second direction) to reset, and the second arm 1220 moves away from the contact point 1110, causing the contact point 1110 to reset. For example, the third arm 1230 is U-shaped. One end of the third arm 1230 is fixedly connected to the rotating part 1240, and the other end is adapted to be exposed to cause the third arm 1230 to undergo elastic deformation. The U-shaped structure of the third arm 1230 can improve the elastic deformation performance of the third arm 1230.

[0061] It is understandable that when at least one of the first arm 1210 and the second arm 1220 undergoes elastic deformation, it can also generate a force on the transmission component 1200, causing the transmission component 1200 to rotate in the second direction. However, since the second arm 1220 needs to touch the contact point 1110, the elastic force generated by the elastic deformation of at least one of the first arm 1210 and the second arm 1220 should not be too large, otherwise it will damage the detection component 1100. The main function of the third arm 1230 is to undergo elastic deformation upon encountering an obstacle, thereby generating a force on the transmission component 1200 that causes the transmission component 1200 to rotate in the second direction. Obstacles can be set according to actual needs to make the third arm 1230 encounter obstacles. For example, the third arm 1230 may encounter an obstacle on the inner wall of the housing 1300. Therefore, the elastic force generated by the elastic deformation of the third arm 1230 can be designed to be relatively large. The greater the force that causes the transmission component 1200 to rotate in the second direction, the more beneficial it is for the rotation and reset of the transmission component 1200.

[0062] Optionally, in some embodiments, when the transmission member 1200 rotates in the first direction, the third arm 1230 first encounters resistance, and then the second arm 1220 touches the contact point 1110. By having the third arm 1230 first encounter resistance and undergo elastic deformation when the transmission member 1200 rotates in the first direction, and then the second arm 1220 touches the contact point 1110, the third arm 1230 can absorb the impact, further reducing the energy of the impact transmitted to the detection member 1100.

[0063] Optionally, in some embodiments, the transmission component 1200 is a one-piece molded part, that is, the transmission component 1200 is manufactured by a one-piece molding method. In this way, the transmission component 1200 has the rotating part 1240, the first support arm 1210, the second support arm 1220, the third support arm 1230 and the reinforcing rib 1250 mentioned above in one-piece molding, which reduces the number of parts and reduces the structural complexity. For example, the transmission component 1200 is manufactured by one-piece molding of plastic.

[0064] Combination Figures 1 to 9As shown, in some embodiments, the door status detection device 1000 further includes a housing 1300 with an opening 1310. A transmission member 1200 is rotatably disposed within the housing 1300, a first support arm 1210 protrudes from the opening 1310, and a detection component 1100 is disposed within the housing 1300. The housing 1300 provides support for the transmission member 1200 and the detection component 1100, enabling the door status detection device 1000 to be modularized and unitized for easy assembly. When the door 2000 is closed, the first support arm 1210 needs to be pushed through the opening 1310. For example, the first door latch 2110 (described below) passes through the opening 1310 to push the first support arm 1210. Optionally, the housing 1300 is provided with a rotating shaft 1320, and the rotating part 1240 is provided with a shaft hole 1241. The transmission member 1200 is rotatably mounted on the rotating shaft 1320 through the shaft hole 1241.

[0065] The second aspect of this application discloses a dishwasher, combined with Figures 1 to 9 As shown, the dishwasher includes a door body 2000 and the aforementioned door status detection device 1000. The door detection device includes a detection component 1100 and a transmission component 1200. The detection component 1100 includes a contact 1110. The transmission component 1200 is rotatably configured and includes a first arm 1210 and a second arm 1220. The first arm 1210 is adapted to be pushed by the door body 2000 to cause the transmission component 1200 to rotate in a first direction. The second arm 1220 is adapted to actuate the contact 1110 when the transmission component 1200 rotates in the first direction. At least one of the first arm 1210 and the second arm 1220 is adapted to elastically deform.

[0066] When the door 2000 closes, it pushes the first arm 1210 of the transmission component 1200, causing the transmission component 1200 to rotate. This rotation causes the second arm 1220 to contact the contact point 1110 of the detection component 1100, thereby connecting or disconnecting the circuit and detecting the state of the door 2000. At least one of the first arm 1210 and the second arm 1220 can elastically deform. This reduces the impact on the detection component 1100 at the moment the second arm 1220 contacts the contact point 1110, helping to extend the service life of the detection component 1100. It is understood that the dishwasher door state detection device 1000 of this embodiment adopts the technical solution of the above embodiment, and therefore includes at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0067] Optionally, in some embodiments, the dishwasher further includes a body 3000, which has a washing chamber and a first latch 3100; the door 2000 includes a first latch 2110, which is adapted to engage with the first latch 3100 and push the first support arm 1210 when the washing chamber is closed along with the door 2000. In this way, the detection component 1100 can be triggered at the same time as the door is closed to realize the status detection of the door 2000.

[0068] Optionally, in some embodiments, the dishwasher further includes a body 3000, which has a washing chamber, a linkage rod 3300, and a second latch 3200; the door 2000 includes a first door 2100 and a second door 2200 that are linked together, the first door 2100 being adapted to open and close a portion of the washing chamber, and the second door 2200 being adapted to open and close another portion of the washing chamber, the second door 2200 including a second latch 2210; wherein, when the first latch 2110 and the first latch 3100 are engaged, the linkage rod 3300 is pushed, so that the linkage rod 3300 pushes the first support arm 1210 and the second latch 3200, and the second latch 3200 is adapted to engage with the second latch 2210 when pushed by the linkage rod 3300.

[0069] The first door 2100 and the second door 2200 are linked, that is, when the first door 2100 closes part of the washing chamber, it can link the second door 2200 to close the other part of the washing chamber, and when the first door 2100 opens part of the washing chamber, it can link the second door 2200 to open the other part of the washing chamber (the linkage of the first door 2100 and the second door 2200 can be active simultaneously or at different times, and at different times means that one of them can be appropriately delayed by the other). The first latch 2110 is rotatably configured. When the first door 2100 closes part of the washing chamber, the inclined surface of the first latch 2110 encounters the first latch position 3100. Under the stop of the first latch position 3100, the first latch 2110 first rotates to avoid it and then rotates back to engage with the first latch position 3100, thus locking the first door 2100. At the same time, the first latch 2110 pushes the linkage rod 3300, which rotates. This causes the linkage rod 3300 to push the first support arm 1210 and the second latch position 3200. The linkage rod 3300 pushes the first support arm 1210, causing the transmission component 1200 to rotate in the first direction, thereby causing the second support arm 1220 to touch the contact point 1110. The linkage rod 3300 pushes the second latch position 3200, which rotates, thus engaging with the second latch 2210 and locking the second door 2200.

[0070] In some embodiments, the door status detection device 1000 and the linkage rod 3300 are respectively disposed on the body 3000. When closing the door, the first door body 2100 needs to move relative to the body 3000. Distributing the door status detection device 1000 and the linkage rod 3300 on the body 3000 facilitates their cooperation with the first door body 2100. Furthermore, the transmission component 1200 is located between the linkage rod 3300 and the detection component 1100, which not only facilitates the first door latch 2110 to transmit force to the detection component 1100 through the linkage rod 3300, but also makes the structural arrangement more compact.

Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
