Description

Technical Field

[0001] This invention relates to the field of dishwasher technology, and more specifically to a breather for a cleaning machine, a cleaning machine, and a water tank type cleaning device. Background Technology

[0002] A dishwasher is a household appliance that automatically cleans dishes, plates, pots, and pans, greatly freeing up people's hands. The breather is an important component of the dishwasher, functioning to balance the pressure inside the drum. It releases gases from the drum to balance the high-pressure gas generated during operation, ensuring the dishwasher's normal operation. Especially during the dish drying stage, hot air entering the drum can easily increase the pressure. In other words, the high-temperature gases generated during dishwasher operation cause excessive pressure inside the drum, requiring gas exchange with the outside through the exhaust duct to balance the pressure inside the drum. The high-temperature gases are expelled through the breather.

[0003] To save space, water flow channels are often integrated into the breather. For example, the Chinese utility model patent disclosed in patent number CN201721604429.7 (publication number CN208573650U), entitled "Breather for a Sink Dishwasher and Sink Dishwasher," includes the following water inlet channel: an upward channel section, the lower end of which is connected to the water inlet; an upwardly protruding bent channel section, one end of which is connected to the upper end of the upward channel section; a rotating channel section, which is arranged side by side with the bent channel section, and one end of which is connected to the other end of the bent channel section; and a downward channel section, the upper end of which is connected to the other end of the rotating channel section, and the lower end of which is connected to the water outlet.

[0004] Currently, most water inlet channels designed for respirators are as shown in the aforementioned patent. The rising and falling sections of the water inlet channel are arranged side by side and adjacent to each other. The water inlet and air inlet are connected through a guide section and a connecting port. The arrangement direction of the rising and falling sections is the width direction of the shell. The rising, falling, and guide sections all extend along the width direction of the shell and are arranged sequentially along the width direction of the shell. This results in the respirator occupying a large space in the width direction of the shell. For sink dishwashers, the sink dishwasher is usually set up with a regular sink. The respirator is set on the side wall of the sink dishwasher facing the regular sink. Foam or other materials are usually stuffed between the sink dishwasher and the regular sink to maintain their stability. However, the respirator occupies too much space in width, which means there is no space to stuff foam or other materials. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a respirator for a cleaning machine that occupies little space in the width direction, in light of the current state of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a cleaning machine that applies the above-mentioned respirator, in view of the current state of the prior art.

[0007] The third technical problem to be solved by the present invention is to provide a water tank type cleaning device that applies the above-mentioned cleaning machine, in view of the current state of the prior art.

[0008] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a breather for a cleaning machine, comprising...

[0009] The housing has a communication opening, a first water inlet and a first water outlet, and an internal water flow channel connecting the first water inlet and the first water outlet.

[0010] The first water flow channel includes

[0011] The upstream section extends from bottom to top, with its lower end connected to the first water inlet.

[0012] The downward section extends from top to bottom, and its lower end is connected to the first outlet. The downward section and the upward section are spaced apart along the width direction of the shell.

[0013] A connecting section connects the upper end of the up section and the upper end of the down section, thereby connecting the up section and the down section, and a through hole is provided on the bottom wall of the connecting section as a siphon inlet;

[0014] The feature is that the connecting section is an upwardly arched arc, a partition is provided between the upper section and the lower section, the partition, the upper section, the lower section and the connecting section together form a cavity that communicates with the siphon port, and a water passage is provided on the shell to connect the cavity and the port, and the water passage and the cavity are arranged sequentially along the thickness direction of the shell.

[0015] To detect the flow rate of the first water flow channel, a flow meter is installed on the first water flow channel, located between the upstream and downstream sections. Since the water flowing out of the first water flow channel typically flows into a water softener for further softening, and a large water flow rate is detrimental to softening, the flow meter controls the water flow to achieve a better softening effect.

[0016] For water tank type washing machines, fruits and vegetables can usually also be washed. Therefore, a second water inlet is provided at the bottom of the housing, and a second water flow channel extending from bottom to top and connected to the second water inlet at its lower end is also provided in the housing. The upper end of the second water flow channel is in fluid communication with a connecting port. Water in the second water flow channel enters the washing chamber of the washing machine through the connecting port, which can wash fruits and vegetables.

[0017] To prevent water from the washing chamber from entering the second water flow channel during the washing process, the upper end of the second water flow channel is higher than the connecting opening. The second water flow channel is connected to the connecting opening through a connecting water channel extending from top to bottom. This is equivalent to elevating the second water flow channel, so even if water from the washing chamber enters the connecting water channel, it will flow back into the washing chamber under the action of gravity.

[0018] To drain the fluid exiting the washing chamber from the connecting port, the housing is also provided with a flow channel connected to the connecting port and an outlet for the fluid to flow out of the flow channel. The flow channel is inverted U-shape. The flow channel can serve as an exhaust pipe; when the pressure in the washing chamber is high, airflow exits from the connecting port and then flows out through the flow channel from the outlet. The flow channel can also serve as an overflow pipe; when overflow occurs, because the flow channel is inverted U-shape, a siphon effect can be created, and water in the washing chamber flows out from the connecting port and then is discharged from the outlet through the flow channel.

[0019] To further facilitate the formation of a siphon effect in the flow channel, the cross-sectional area of ​​the flow channel, at least in the section adjacent to the connection port, gradually decreases along the direction of fluid flow.

[0020] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: a cleaning machine using the above-mentioned respirator, characterized in that: it further includes a tank with a washing chamber, the top of the washing chamber is open, an air passage opening connected to the washing chamber is provided on the first side wall of the tank, the housing is installed on the first side wall of the tank, and the communication port of the housing is correspondingly connected to the air passage opening of the tank.

[0021] Typically, airflow needs to be introduced into the washing chamber to dry the dishes, etc. To reduce the number of openings, the housing is also provided with an air duct connected to the connecting port and an air vent connecting the air duct to the outside. The air duct is provided with a first airflow driving component for driving the airflow from the air vent to the connecting port. In this way, the connecting port serves multiple purposes, not only allowing the airflow in the washing chamber to be discharged outwards, but also allowing external airflow to flow into the washing chamber.

[0022] The first airflow drive component can have various structural forms. In the simplest case, the first airflow drive component is a first fan. The air inlet of the first fan is in fluid communication with the air outlet, and the air outlet of the first fan is in fluid communication with the connecting port.

[0023] To improve the drying effect on the tableware in the washing chamber, an air inlet is provided on the second side wall of the tank to allow external airflow into the washing chamber. The first and second side walls of the tank are arranged opposite to or adjacent to each other. The airflow entering the washing chamber from the air inlet and the airflow entering the washing chamber from the air outlet can collide, making the gas flow field distribution in the washing chamber more uniform and the drying effect better.

[0024] To further improve the drying effect, an air inlet duct is provided on the second side wall of the tank. The air outlet of the air inlet duct is fluidly connected to the air inlet of the tank, and the air inlet of the air inlet duct is fluidly connected to the outside. A heating element is provided in the air inlet duct and / or air channel. The air inlet duct serves to collect and guide air, while the heating element heats the airflow, thereby improving the drying effect.

[0025] In order to drive the airflow from the air inlet of the air inlet duct to the air outlet, the air inlet duct is provided with a second airflow driving element for driving the airflow from the air inlet of the air inlet duct to the air outlet.

[0026] The second airflow drive component can have various structural forms. In a simple form, the second airflow drive component is a second fan. The air inlet of the second fan is fluidly connected to the air inlet of the air inlet pipe, and the air outlet of the second fan is fluidly connected to the air outlet of the air inlet pipe.

[0027] To improve the versatility of the respirator, the housing is also provided with an air outlet pipe that communicates with the communication port. The air outlet pipe can be opened or closed by a blocking component. Furthermore, a blocking plate that can open or close the air outlet of the first fan is movably provided in the air duct. When the air outlet pipe is blocked, the blocking plate opens the air outlet of the first fan. When the air outlet pipe is open, the blocking plate closes the air outlet of the first fan.

[0028] For washing machines without a top door mechanism, the air outlet is opened during the drying process. At this time, the hot air flowing out of the washing chamber can be discharged through the air outlet. The baffle plate blocks the air outlet of the first fan to prevent the hot air discharged from the washing chamber from entering the first fan and eventually being discharged into the user's cabinet, forming condensate and causing a bad user experience.

[0029] For washing machines equipped with a top door mechanism, during the drying process, the top door mechanism can lift the door body with the rotating cover on the top of the tank, close the air outlet pipe, and open the air outlet of the first fan with the baffle plate. Airflow is input into the washing chamber from both the air inlet pipe and the air duct, forming a collision flow to dry the tableware. At the same time, the air in the washing chamber can be discharged from the washing chamber through the gap between the door body and the tank body and the flow channel.

[0030] To facilitate the opening and closing of the air outlet of the first fan by the baffle plate, the upper end of the baffle plate is rotatably mounted on the housing via a pivot extending along the thickness direction of the housing. The lower end of the baffle plate is free. In the free state, the baffle plate is vertically positioned and blocks the air outlet of the first fan. When the first fan is working, the airflow blows the baffle plate to open the air outlet of the first fan; when the first fan is not working, the baffle plate is in a vertical state, and the airflow discharged from the connecting port blows the baffle plate toward the air outlet of the first fan, thereby closing the air outlet of the first fan.

[0031] Preferably, the air outlet pipe is connected to the air duct through an air passage hole, the air passage hole is located adjacent to the air outlet hole of the first fan, and a baffle is provided at the air passage hole in the flow path of the airflow from the air outlet hole, the baffle partially blocking the air passage hole. The function of the baffle is to prevent the airflow from the air outlet hole from flowing directly to the air outlet pipe, thereby reducing airflow loss.

[0032] The technical solution adopted by the present invention to solve the third technical problem mentioned above is: a water tank type cleaning device using the above-mentioned cleaning machine, characterized in that: it further includes a water tank, the water tank and the tank body are arranged side by side, and the first side wall of the tank body faces the water tank.

[0033] Compared with the prior art, the advantages of the present invention are: by arranging the water passage and the first water flow passage sequentially along the thickness direction of the shell, the present invention makes full use of the space in the thickness direction of the shell, and can reduce the area occupied by the first water flow passage and the water passage in the width direction of the shell, so as to fill some materials, such as foam, in the space between the tank and the water tank on both sides of the width direction of the shell to stabilize the water tank and the tank.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0044] like Figures 1-9 As shown, the preferred embodiment of the water tank type cleaning device includes a water tank A and a cleaning machine. The cleaning machine includes a tank body 1 and a breather B. The water tank A and the tank body 1 are arranged side by side, and the first side wall 12 of the tank body 1 faces the water tank A. The tank body 1 has a washing chamber 11 with an open top. The top of the tank body 1 is rotatably provided with a door that can open or close the washing chamber 11 (not shown in the figure, this is prior art and will not be described in detail here).

[0045] The respirator B includes a housing 2, which is mounted on the first side wall 12 of the tank 1. The first side wall 12 of the tank 1 has an air passage 13 that communicates with the washing chamber 11. The housing 2 has a connecting port 21, which corresponds to and communicates with the air passage 13 of the tank 1.

[0046] like Figure 6 , 7 As shown, the bottom of the housing 2 is provided with a first water inlet 22 and a first water outlet 23. Of course, the first water inlet 22 and the first water outlet 23 can also be located on the side wall of the housing 2 but near the bottom. The housing 2 has a first water flow channel 24 that connects the first water inlet 22 and the first water outlet 23. The water in the first water flow channel 24 is used to clean the tableware. Therefore, the first water outlet 23 is usually connected to a water softener to soften the water before it is delivered to the washing chamber 11.

[0047] The first water flow channel 24 includes an upward section 241, a downward section 242, and a connecting section 243. The upward section 241 extends from bottom to top and its lower end is connected to the first inlet 22. The downward section 242 extends from top to bottom and its lower end is connected to the first outlet 23. The downward section 242 and the upward section 241 are spaced apart along the width direction of the housing 2. The connecting section 243 connects the upper end of the upward section 241 and the upper end of the downward section 242, thereby connecting the upward section 241 and the downward section 242. A through hole is provided on the bottom wall of section 243 as a siphon port 244. The connecting section 243 is an upwardly arched arc. A partition 247 is provided between the upward section 241 and the downward section 242. The partition 247, the upward section 241, the downward section 242 and the connecting section 243 together form a cavity 245 that is connected to the siphon port 244. A water passage 246 is provided on the shell 2 to connect the cavity 245 and the connecting port 21. The water passage 246 and the cavity 245 are arranged sequentially along the thickness direction of the shell 2.

[0048] The upward segment 241 mentioned above extends from bottom to top, and the downward segment 242 extends from top to bottom. This does not mean that the upward segment 241 and the downward segment 242 are in a straight line. They can also extend in a roundabout way. For example, the upward segment 241 may extend downward in part and then upward again. As long as the upper end of the upward segment 241 is higher than its lower end and the upper end of the downward segment 242 is higher than its lower end, it is acceptable. In order to reduce water loss and prevent a large amount of water from flowing out of the siphon 244, the siphon 244 can be set to a smaller size, or a baffle can be set at the siphon 244 to reduce the water passage area of ​​the siphon 244.

[0049] This makes full use of the space in the thickness direction of the shell 2, which can reduce the area occupied by the first water flow channel 24 and the water passage channel 246 in the width direction of the shell 2, so as to ensure that there is room between the water tank A and the tank body 1 to fill foam or other materials for stabilizing the water tank A and the tank body 1.

[0050] A flow meter 248 is installed on the first water flow channel 24, located between the upstream section 241 and the downstream section 242. Because a large water flow rate is detrimental to water softening, the flow meter 248 is installed to control the water flow rate and achieve a better softening effect. In this embodiment, the flow meter 248 is a turbine flow meter.

[0051] For water tank type washing machines, fruits and vegetables can usually also be washed. Therefore, the bottom of the housing 2 is provided with a second water inlet 25. The housing 2 is also provided with a second water flow channel 251 that extends from bottom to top and whose lower end is connected to the second water inlet 25. The upper end of the second water flow channel 251 is in fluid communication with the connecting port 21.

[0052] To prevent water from the washing chamber 11 from entering the second water flow channel 251 during the washing process, the upper end of the second water flow channel 251 is higher than the connecting port 21. The second water flow channel 251 is connected to the connecting port 21 through a connecting water channel 252 extending from top to bottom. Water in the second water flow channel 251 enters the washing chamber 11 of the washing machine through the connecting port 21 to wash fruits and vegetables. At the same time, the design of the connecting water channel 252 is equivalent to raising the second water flow channel 251, so even if water from the washing chamber 11 enters the connecting water channel 252, it will flow back into the washing chamber 11 under the action of gravity.

[0053] The housing 2 is also provided with a flow channel 26 communicating with the connecting port 21 and an outlet 261 for the fluid to flow out of the flow channel 26. The flow channel 26 is inverted U-shape. The flow channel 26 can serve as an exhaust pipe. When the pressure in the washing chamber 11 is high, the airflow flows out from the connecting port 21 and then flows out from the outlet 261 through the flow channel 26. The flow channel 26 can also serve as an overflow pipe. When overflow occurs, because the flow channel 26 is inverted U-shape, a siphon effect can be generated. The water in the washing chamber 11 flows out from the connecting port 21 and then is discharged from the outlet 261 through the flow channel 26. In this embodiment, the cross-sectional area of ​​the flow channel 26, at least in the section adjacent to the connecting port 21, gradually decreases along the direction of fluid flow, further facilitating the formation of a siphon effect in the flow channel 26.

[0054] like Figures 2-6 As shown, the housing 2 is also provided with an air duct 27 connected to the connecting port 21, and an air outlet 271 connecting the air duct 27 to the outside. The air duct 27 is provided with a first airflow driving component 3 for driving airflow from the air outlet 271 to the connecting port 21. The first airflow driving component 3 is a first fan. The air inlet of the first fan is fluidly connected to the air outlet 271, and the air outlet of the first fan is fluidly connected to the connecting port 21. The connecting port 21 has multiple uses, not only allowing airflow from the washing chamber 11 to be discharged to the outside, but also allowing external airflow to flow into the washing chamber 11.

[0055] The second side wall 14 of the tank body 1 is also provided with an air inlet 15 for external airflow to flow into the washing chamber 11. The first side wall 12 and the second side wall 14 of the tank body 1 are arranged opposite to or adjacent to each other. The second side wall 14 of the tank body 1 is provided with an air inlet pipe 4. The air inlet pipe 4 is provided with an air inlet hole 42 and an air outlet hole 43 that are connected to its interior. The air outlet hole 43 of the air inlet pipe 4 is in fluid communication with the air inlet 15 of the tank body 1, and the air inlet hole 42 of the air inlet pipe 4 is in fluid communication with the outside.

[0056] The air inlet duct 4 is provided with a second airflow drive 5 for driving airflow from the air inlet hole 42 of the air inlet duct 4 to the air outlet hole 43. The second airflow drive 5 is a second fan. The air inlet of the second fan is in fluid communication with the air inlet hole 42 of the air inlet duct 4, and the air outlet of the second fan is in fluid communication with the air outlet hole 43 of the air inlet duct 4.

[0057] A heating element 41 is provided in the air inlet duct 4. Of course, the heating element 41 can also be set in the air duct 27. The heating element 41 can be a PTC heating element.

[0058] The airflow entering the washing chamber 11 from the air inlet 15 and the airflow entering the washing chamber 11 from the air outlet 13 can collide, making the gas flow field distribution in the washing chamber 11 more uniform and the drying effect better.

[0059] like Figure 6 , 8 As shown in Figure 9, in order to improve the versatility of the respirator, the housing 2 is also provided with an air outlet pipe 6 connected to the communication port 21. The air outlet pipe 6 can be opened or closed by a shielding component, and a shielding plate 7 is movably provided in the air duct 27 to open or close the air outlet 31 of the first fan. When the air outlet pipe 6 is blocked, the shielding plate 7 opens the air outlet 31 of the first fan. When the air outlet pipe 6 is open, the shielding plate 7 closes the air outlet 31 of the first fan.

[0060] In this embodiment, the upper end of the baffle plate 7 is rotatably mounted on the housing 2 via a rotating shaft 71 extending along the thickness direction of the housing. The lower end of the baffle plate 7 is a free end. When the baffle plate 7 is in a free state, it is vertically positioned and blocks the air outlet 31 of the first fan. When the first fan is working, the airflow blows the baffle plate 7 to open the air outlet 31 of the first fan. When the first fan is not working, the baffle plate 7 is in a vertical state, and the airflow discharged from the connecting port 21 blows the baffle plate 7 toward the air outlet 31 of the first fan, thereby closing the air outlet 31 of the first fan.

[0061] The air outlet 6 can be opened or closed by manually inserting or removing the blocking block into it.

[0062] In addition, the air outlet pipe 6 is connected to the air duct 27 through the air passage 61. The air passage 61 is located near the air outlet 31 of the first fan, and a baffle 62 is provided at the air passage 61 in the flow path of the airflow from the air outlet 31, partially blocking the air passage 61. The function of the baffle 62 is to prevent the airflow from the air outlet 31 from flowing directly to the air outlet pipe 6, reducing airflow loss, and to direct the airflow from the air outlet 31 toward the connecting port 21.

[0063] For washing machines without a top door mechanism 8, during the drying process, the air outlet pipe 6 is opened. At this time, the hot air flowing out of the washing chamber 11 can be discharged through the air outlet pipe 6 and the flow channel 26. The baffle plate 7 blocks the air outlet 31 of the first fan to prevent the hot air discharged from the washing chamber 11 from entering the first fan and eventually being discharged into the user's cabinet, forming condensate and causing a bad user experience.

[0064] For a washing machine equipped with a top door mechanism 8, during the drying process, the top door mechanism can lift the door body with the rotating cover on the top of the tank body 1, close the air outlet pipe 6 through the shielding component, the first fan works, the shielding plate 7 opens the air outlet 31 of the first fan, and airflow is input into the washing chamber 11 from both the air inlet pipe 4 and the air duct 27, forming a collision flow to dry the tableware. At the same time, the air in the washing chamber 11 can be discharged from the washing chamber 11 through the gap between the door body and the tank body 1 and the flow channel 26.

[0065] The top door mechanism described above can be achieved using existing technologies, and will not be elaborated upon here.

[0066] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this invention can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0067] The term "fluid connectivity" as used in this invention refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. This third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.
