[0003] The above patent further discloses the following content: multiple partitions are provided to divide the space in the housing 1 into multiple independent cavities. For example, a first partition 103' is provided in the middle of the housing 1 to separate the upper cavity 101' and the lower cavity 102'. The lock 11 is connected to the upper cavity 101'. The lock 4 and the first torsion spring 5' are provided in the upper cavity 101'. The first partition 103' has an opening for the ejector 3 to pass through. The upper part of the ejector 3 is located in the upper cavity 101', and the lower part of the ejector 3 is located in the lower cavity 102'.

[0004] However, existing washing machines using door lock structures, especially sink dishwashers with flush doors, have a great risk of causing the washing water inside the washing machine or the user's own washing water to flow into the upper chamber of the door lock structure. The water entering the upper chamber will flow into the lower chamber through the through hole on the first partition (for the ejector to pass through) and drip directly onto the second elastic member. When the second elastic member is actuated, the water will bounce onto the trigger sheet of the microswitch, causing the microswitch to short-circuit, and then a fault error will occur. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a door lock structure for a cleaning machine that can avoid malfunctions caused by water ingress, with respect to the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a cleaning machine with the above-mentioned door lock structure in view of the prior art.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a door lock structure for a cleaning machine, comprising:

[0008] A shell, wherein the interior space of the shell is divided into an upper chamber and a lower chamber by a first partition;

[0009] An ejector member is vertically inserted into the through hole of the first partition plate and can move up and down relative to the through hole;

[0010] A first elastic member is disposed in the lower chamber and below the ejector member, and enables the ejector member to always maintain an upward trend;

[0011] A micro switch is arranged in the lower chamber and spaced apart from the first elastic member and is used to connect the electrical signal to the main controller of the cleaning machine; it is characterized by further comprising:

[0012] The first air channel is arranged inside the shell, and the first air inlet end thereof is communicated with the outside, while the first air outlet end leads to the micro switch.

[0013] Furthermore, it also includes a second air channel, which is arranged outside the shell, and the second air inlet end of the second air channel is connected to the outside, and the second air outlet end is fluidically connected to the first air inlet end of the first air channel.

[0014] Furthermore, it also includes a fan for blowing outside air into the second air passage and a heating device for heating the gas in the second air passage. In this way, the gas can be efficiently introduced into the first air passage through the second air passage, thereby improving the gas outlet efficiency of the first air passage and thus the drying efficiency. The gas in the second air passage is heated by the heating device, so that the gas entering the first air passage has a certain temperature, which can improve the drying effect compared with direct drying with cold air.

[0015] Furthermore, the second air outlet of the second air channel is also in fluid communication with the air inlet on the washing chamber of the cleaning machine, so that the second air channel can also be used for drying the inside of the washing chamber after cleaning.

[0016] Furthermore, the second air passage is a drying passage of the cleaning machine, so that the original relevant structure of the cleaning machine does not need to be modified, and the gas can be introduced and heated by using the original drying passage.

[0017] Furthermore, the first air channel is located in the lower chamber and above the micro switch, and the triggering piece of the micro switch is arranged upward, and the first air outlet of the first air channel leads to the triggering piece. In this way, the air outlet of the first air channel can directly blow the triggering piece of the micro switch, so as to better dry the triggering piece.

[0018] Furthermore, a second partition and a third partition are provided in the lower chamber to separate the above-mentioned first air channel, so as to facilitate the construction of the first air channel in the lower chamber. The cross-sectional size of the first air channel first increases and then decreases along the air flow direction. On the one hand, it is beneficial to introduce the gas into the first air channel, and on the other hand, it can make the gas in the first air channel discharge at a certain flow rate, thereby further ensuring the drying effect on the trigger sheet.

[0019] Furthermore, the first air inlet end of the first air channel is located at the lower part of the first air channel and extends vertically, while the middle part of the first air channel extends horizontally and is square, a lower air vent in fluid communication with the first air inlet end is provided on one side of the lower end of the middle part, and an upper air vent in fluid communication with the first air outlet end of the first air channel is provided on the other side of the upper end of the middle part, and the upper air vent and the lower air vent are located on the diagonal line of the middle part. Thus, the airflow entering the first air channel can be combed and guided, ensuring that the airflow flows smoothly in the first air channel, thereby ensuring the drying efficiency.

[0020] Furthermore, the trigger piece of the micro switch extends horizontally, the first outlet end of the first air channel extends in an inverted U shape, and the air inlet side of the first outlet end is inclined outward along its own length direction and communicated with the upper air vent, while the air outlet side extends vertically and leads to the trigger piece of the micro switch, and the inner side wall at the first outlet of the first outlet end protrudes downward and outward from its outer side wall and is inclined toward the outer side wall, and the free end of the outer side wall extends horizontally outward. Thus, the air outlet of the first air channel can flow along the trigger piece and better dry the trigger piece.

[0021] Furthermore, a liquid baffle is provided between the first elastic member and the upper micro switch. Water in the upper chamber drips onto the first elastic member through the through hole, and the first elastic member will bounce the water onto the micro switch when deformed. The liquid baffle can block the water that bounces onto the micro switch.

[0022] Furthermore, the liquid baffle plate includes a first baffle plate and a second baffle plate arranged vertically, the first baffle plate and the second baffle plate are arranged opposite to each other and spaced apart and both are metal plates, and the first baffle plate is provided with a first steam hole and the second baffle plate is provided with a second steam hole staggered from the first steam hole. In this way, on the basis of ensuring the water-blocking effect, the water vapor entering from the through hole can enter the gap between the first baffle plate and the second baffle plate when flowing toward the micro switch, and stay in the gap to be condensed, thereby significantly reducing the amount of water vapor flowing to the micro switch.

[0023] Furthermore, the first air channel and the liquid baffle are respectively arranged on both sides of the micro switch, and the air outlet of the first air channel can flow to the liquid baffle, so that the air outlet of the first air channel can dry the condensed water at the liquid baffle, thereby achieving self-cleaning of the condensed water.

[0024] The technical solution adopted to further solve the above second technical problem is: a cleaning machine, characterized in that it includes the door lock structure for the cleaning machine as described above.

[0025] Compared with the prior art, the present invention has the advantages that: the present invention is provided with a first air passage, the first air inlet end of the first air passage is communicated with the outside, and the first air outlet end is connected to the micro switch. In this way, the lower chamber can be dried by the air outlet of the first air passage, especially the micro switch, to prevent the triggering piece of the micro switch from being corroded and rusted, thereby causing a door lock structure failure.

[0037] The door lock structure of this embodiment is used to lock any door body and box body. This embodiment is described by taking a water tank type cleaning machine as an example. Figures 1 to 9 As shown, the cleaning machine in this embodiment includes a housing 1 and a door 3. The housing 1 has a washing chamber 10 and an upper port connected to the top of the washing chamber 10. An edge of the door 3 is rotatably connected to the edge of the upper port of the housing 1.

[0038] Further, the door lock structure 2 for the cleaning machine in this embodiment includes a housing 4, an ejector 5, a first elastic member 6, a micro switch 7 and a lock rod 31. The lock rod 31 is vertically mounted on the lower wall of the door body 3 and arranged close to the edge, while the housing 4, the ejector 5, the first elastic member 6, the micro switch 7, etc. are all mounted on one side of the box body 1 and arranged close to the upper edge of the box body 1, as shown in FIG. Figure 2 As shown. The top wall of the shell 4 is provided with a lock opening 41 which passes through from top to bottom. The lower end of the lock rod 31 has a C-shaped lock hook 311. The lock hook 311 can move up and down through the lock opening 41 on the shell 4, and can penetrate into the lock opening 41 on the shell 4 and be located inside the shell 4 when the door is locked, and can pass out of the lock opening 41 and be located above the shell 4 when the door is unlocked. The ejector 5 is located inside the shell 4 and can be moved up and down below the lock opening 41. A support 11 extending horizontally outward is formed at the edge of the upper port of the box body 1. An opening 111 is formed on the support 11 corresponding to the arrangement of the lock opening 41. When the door is opened, the upper end of the ejector 5 is basically horizontally aligned with the opening 111. Further, as Fig. 9As shown, the shell 4 is divided into an upper chamber 401 and a lower chamber 402 by a first partition 42, and the ejector 5 is vertically arranged in the through hole 420 of the first partition 42 and can move up and down relative to the through hole 420. The first elastic member 6 and the micro switch 7 are both arranged in the lower chamber 402 of the shell 4, and are arranged side by side and spaced from left to right. Specifically, a convex block 52 having a width greater than that of the ejector 5 is provided at the lower part of the ejector 5, and the first elastic member 6 is mounted on the convex block 52, so that the ejector always maintains an upward trend. In this embodiment, the first elastic member 6 is specifically a torsion spring. The micro switch 7 is arranged side by side and spaced from left to right with the first elastic member 6, and is used to connect the electrical signal of the main controller of the cleaning machine. For details, please refer to the applicant's prior application CN201910933576.6 (publication number CN 112576111A).

[0039] Furthermore, the door lock structure 2 further comprises a first air passage 81, which is arranged inside the housing 4, and whose first air inlet end 811 is communicated with the outside, and whose first air outlet end 813 is connected to the micro switch 7. In this way, the present invention can dry the lower chamber 402, especially the micro switch 7, through the air outlet of the first air passage 81, so as to prevent the triggering piece 71 of the micro switch 7 from being corroded and rusted, thereby causing the door lock structure 2 to malfunction.

[0040] Further, it also includes a second air duct 82, which is arranged outside the above-mentioned housing 4, and the second air inlet end 821 of the second air duct 82 is connected to the outside, and the second air outlet end 822 is in fluid communication with the first air inlet end 811 of the above-mentioned first air duct 81. In addition, it also includes a fan 823 for blowing outside air into the second air duct 82 and a heating device 824 for heating the gas in the second air duct 82. In this way, the gas can be efficiently introduced into the first air duct 81 through the second air duct 82, thereby improving the gas outlet efficiency of the first air duct 81, and then the drying efficiency, and the gas in the second air duct 82 is heated by the heating device 824, so that the gas entering the first air duct 81 has a certain temperature, which can improve the drying effect compared with direct drying with cold air. In this embodiment, the second air outlet end 822 of the second air duct 82 is connected to the first air inlet end 811 of the first air duct 81 through the air outlet pipe 83.

[0041] Preferably, the second air outlet end 822 of the second air duct 82 is also fluidically connected to the air inlet 100 on the washing chamber 10 of the cleaning machine. In this way, the second air duct 82 can also be used for drying the inside of the washing chamber 10 after cleaning is completed. Further preferably, the second air duct 82 is a drying channel of the cleaning machine. In this way, there is no need to change the original related structure of the cleaning machine, and the gas can be introduced and heated by using the original drying channel. In this embodiment, the second air duct 82 is arranged on the other side of the box body 1 (specifically, it is formed by the air guide plate 820 being covered on the corresponding side of the box body 1), and the heating device 824 is a PTC heating plate.

[0042] Furthermore, the first air passage 81 is located in the lower chamber 402 and above the micro switch 7, and the trigger piece 71 of the micro switch 7 is arranged upward, and the first air outlet 813 of the first air passage 81 leads to the trigger piece 71. In this way, the air outlet of the first air passage 81 can directly blow the trigger piece 71 of the micro switch 7, so that the trigger piece 71 can be better dried.

[0043] In this embodiment, the second partition plate 43 and the third partition plate 44 are provided in the lower chamber 402 to separate the first air passage 81, so as to facilitate the construction of the first air passage 81 in the lower chamber 402. The cross-sectional size of the first air passage 81 increases first and then decreases along the air flow direction, which is beneficial to the introduction of gas into the first air passage 81 on the one hand, and can make the gas in the first air passage 81 out at a certain flow rate on the other hand, further ensuring the drying effect of the trigger sheet 71. Specifically, the first air inlet end 811 of the first air channel 81 is located at the lower part of the first air channel 81 and extends vertically, while the middle part 812 of the first air channel 81 extends horizontally and is square, and a lower air vent 8122 in fluid communication with the first air inlet end 811 is provided on one side of the lower end of the middle part 812, and an upper air vent 8121 in fluid communication with the first air outlet end 813 of the first air channel 81 is provided on the other side of the upper end of the middle part 812, and the upper air vent 8121 and the lower air vent 8122 are located on the diagonal line of the middle part 812. Thus, the airflow entering the first air channel 81 can be combed and guided to ensure smooth flow of the airflow in the first air channel 81, thereby ensuring the drying efficiency.

[0044] Preferably, the triggering piece 71 of the micro switch 7 extends horizontally, the first air outlet end 813 of the first air channel 81 extends in an inverted U shape, and the air inlet side of the first air outlet end 813 is inclined outward along its own length direction and communicated with the upper air vent 8121, while the air outlet side extends vertically and leads to the triggering piece 71 of the micro switch 7, and the inner side wall at the first air outlet 8130 of the first air outlet end 813 protrudes downward and outward from its outer side wall and is inclined toward the outer side wall, and the free end of the outer side wall extends horizontally outward. Thus, the air outlet of the first air channel 81 can flow along the triggering piece 71 to better dry the triggering piece 71.

[0045] Furthermore, a liquid baffle plate 9 is provided between the first elastic member 6 and the upper micro switch 7. The water in the upper chamber 401 drips onto the first elastic member 6 through the through hole 420. When the first elastic member 6 is deformed, the water will be bounced onto the micro switch 7. The liquid baffle plate 9 can block the water that is bounced onto the micro switch 7. In this embodiment, preferably, the liquid baffle plate 9 is located on the right side of the micro switch 7 (e.g., Figure 5 and Figure 6 As shown), the first air channel 81 is arranged on the upper left side of the micro switch 7, wherein the first air outlet 8130 of the first air channel 81 is vertically opposite to one end of the trigger sheet 71 and faces the liquid baffle plate 9.

[0046] Specifically, the above-mentioned liquid baffle plate 9 includes a first baffle plate 91 and a second baffle plate 92 arranged vertically, and the first baffle plate 91 and the second baffle plate 92 are arranged opposite to each other and are both metal plates (specifically sheet metal plates), and the first baffle plate 91 is provided with a first steam hole 910 and the second baffle plate 92 is provided with a second steam hole 920 staggered from the first steam hole 910. In this way, on the basis of ensuring the water-blocking effect, the water vapor entering from the through hole 420 can enter the gap between the first baffle plate 91 and the second baffle plate 92 when flowing toward the micro switch, and stay in the gap and condense, thereby significantly reducing the amount of water vapor flowing to the micro switch. Further, the above-mentioned first air duct 81 and the liquid baffle plate 9 are respectively arranged on both sides of the above-mentioned micro switch 7, and the outlet air of the first air duct 81 can flow to the above-mentioned liquid baffle plate 9. In this way, the outlet air of the first air duct 81 can dry the condensed water at the liquid baffle plate 9, and realize the self-cleaning of the condensed water. In this embodiment, specifically, an upper mounting seat 93 and a lower mounting seat 94 are respectively arranged in the lower chamber along the thickness direction of the shell 4, wherein the lower mounting seat 93 is located on the inner bottom surface of the lower chamber 401, and the upper mounting seat 93 is directly above the lower mounting seat 94, and the two are arranged at intervals from top to bottom. In addition, upper slots 931 corresponding to each baffle are respectively opened on the upper mounting seat 93, and the two upper slots 931 extend along the length direction of the upper mounting seat 93 and are arranged at intervals from left to right, and both are open downward. At the same time, lower slots 941 corresponding to each baffle are respectively opened on the lower mounting seat 94, and the two lower slots 941 extend along the length direction of the lower mounting seat 94 and are arranged at intervals from left to right, and both are open upward. The upper ends of the first baffle plate 91 and the second baffle plate 92 are respectively inserted into the corresponding upper slots 931 along their own length directions, and the lower ends of the first baffle plate 91 and the second baffle plate 92 are respectively inserted into the corresponding lower slots 941 along their own length directions, thereby realizing the installation of the liquid baffle plate 9 in the lower chamber 402.

The first part and the second part can be directly connected to each other, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
