Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a commodity or system that includes the element.
At present, because of the fact that a plurality of barrels of washing machines occupy more space due to the fact that an internal waterway system occupies more space, and the internal waterway pipelines of the plurality of barrels of washing machines are complex, redundant and not easy to install, the problem of water retention exists in the waterway system of the washing machine. The invention provides a new layout method of a multi-barrel washing machine waterway system by improving the waterway system of the multi-barrel washing machine; in addition, the multi-tub washing machine also comprises an integrated water box, a water pipe and a mixing cavity which are connected among a plurality of devices, and the like, wherein a pressure stabilizing airflow valve assembly is additionally arranged on the mixing cavity, so that the external atmosphere forms one-way conduction to the inner side of the water box structure and/or the mixing cavity to achieve air pressure balance. The pressure stabilizing airflow valve component comprises a pressure stabilizing airflow valve with a lower cone and a rear circle and a gland.
To further illustrate the waterway system of the present invention, the following specific embodiments are now provided in conjunction with fig. 1-9.
Example 1
As shown in fig. 1 to 9, the present invention provides a waterway system of a washing machine, the waterway system including: a water box structure 10 and a dispensing device 1. The water box structure 10 is used for providing corresponding water flow channels for a plurality of washing tubs of the washing machine, and the water box structure 10 is arranged between a water inlet main pipe of the washing machine and the plurality of washing tubs; this put in device 1 connects and establishes in the rivers passageway of water box structure 10, includes: a mixing chamber for mixing the washing solution with water; wherein a pressure-stabilizing airflow valve assembly 1004 is arranged on the mixing cavity and/or the water box structure, and the pressure-stabilizing airflow valve assembly 1004 is used for making the external atmosphere form one-way conduction towards the inner side of the water box structure and/or the mixing cavity so as to achieve air pressure balance.
The water path system is additionally provided with the pressure stabilizing airflow valve component 1004, thereby reducing the retention water in the washing machine and prolonging the service life of the washing machine; the one-way conduction of the waterway system and the atmosphere is realized, namely the atmosphere can be conducted to the water box structure and/or the mixing cavity, and the water in the water box structure and/or the mixing cavity can not be conducted to the atmosphere. The pressure-stabilizing airflow valve has small volume and is convenient to use on a water box structure and a mixing cavity; the pressure stabilizing airflow valve 1007 and the gland 1008 can be arranged on a shell of a closed waterway system of the washing machine; the integrated waterway system improves the space utilization rate inside the washing machine.
Preferably: the mixing chamber includes a mixing chamber upper cover 1006 and a mixing chamber lower cover 1005. The mixing chamber upper cover 1006 and the mixing chamber lower cover 1005 are matched to form the mixing chamber, and a mixing chamber upper cover water inlet 1003 and a mixing chamber upper cover water outlet 1002 which are communicated with the inside of the mixing chamber are formed on the mixing chamber upper cover 1006. The mixing chamber upper cover water inlet 1003 may be used as an inlet of the drop device and the mixing chamber upper cover water outlet 1002 may be used as an outlet of the drop device.
Further, the releasing device further comprises: a reservoir and an infusion pump 1001. The liquid storage box is used for storing washing solution and is provided with a liquid storage box inlet and a liquid storage box outlet; the inlet of the aspiration pump 1001 is in communication with the reservoir outlet and the outlet of the aspiration pump 1001 is in communication with the mixing chamber.
When water enters into a plurality of barrels of the multi-barrel washing machine simultaneously, the pressure of the water path system is up to 1MPa, the pressure stabilizing airflow valve which is installed independently is difficult to resist the pressure of the water path system, a gland structure of the pressure stabilizing airflow valve is needed at the moment, the pressure stabilizing airflow valve is installed on the shell through a buckle, and the end face of the pressure stabilizing airflow valve abuts against the pressure stabilizing airflow valve 1007, so that the pressure of the water path system borne by the pressure stabilizing airflow valve is increased. Preferably, the regulated pressure air flow valve assembly 1004 is disposed on the mixing chamber cover 1006. Further, the regulated airflow valve assembly 1004 includes: a surge gas flow valve 1007 and a gland 1008. The pressure-stabilizing airflow valve 1007 is detachably connected to the mixing chamber, preferably: the connection mode is clamping connection; the gland 1008 is provided on the mixing chamber for reinforcing the pressure regulator airflow valve. The pressure stabilizing airflow valve 1007 is additionally provided with the pressing cover 1008, so that the pressure of a waterway system born by the pressure stabilizing airflow valve is increased, and the pressure stabilizing airflow valve is prevented from being flushed out due to overlarge pressure of the waterway system.
Preferably: the pressure stabilizing airflow valve 1007 is in the shape of a lower cone and a rear circle. The pressure stabilizing airflow valve 1007 mainly includes: the rubber buffer and the air flow mouth that forms on the mixing chamber upper cover, rubber buffer and air flow mouth interference fit. It should be noted that the pressure-stabilizing airflow valve 1007 may be disposed on the mixing chamber upper cover 1006, and similarly may also be disposed on the water box structure 10, or may also be disposed on the housing of other closed waterways.
The middle hole on the rubber plug of the pressure stabilizing airflow valve 1007 is a slender through hole, when water enters, because the water pressure exists, the water pressure presses the inclined plane of the pressure stabilizing airflow valve to close the slender hole, thereby achieving the requirement of no water leakage; when water inflow stops, water pressure disappears, the internal pressure of the mixing cavity is smaller than the external pressure, the elongated hole is opened under the action of the atmospheric pressure, the internal and external air pressures of the mixing cavity are balanced, and water flows out under the action of gravity, so that residual water in the mixing cavity is reduced. Similarly, the same principle can be applied to the pressure stabilizing airflow valve installed in the water box structure 10 or other housing of the waterway system to reduce the water retention in the waterway system.
Preferably, a gating structure and a plurality of water box runners are provided on the water box structure 10. The gating structure is communicated with the water inlet main pipe through a gating structure inlet on the gating structure, and is correspondingly communicated with the washing barrels through a plurality of gating structure outlets on the gating structure. A plurality of water box flow channels are arranged in parallel and penetrate through the interior of the water box structure 10. In the multiple water box runners: at least one water box first flow channel 101 connected between the outlet of the gating structure and the washing barrel, and/or at least one water box second flow channel 102 connected between the water inlet main pipe and the washing barrel. Because the existing multi-barrel washing machine has more internal water channel pipelines, the structure is complex, and the installation and layout are not easy; the layout of the water channel pipelines in the multi-barrel washing machine occupies too much internal space, and is not beneficial to the volume control of the whole machine on the premise of originally limited space; the pipeline is too long and is not easy to fix; the pipelines are too many, and after the pipeline is used for a long time, the pipelines are seriously abraded between the pipelines, and between the pipelines and the barrel body or the shell; in addition, the problem of residual water is likely to occur in the water path. The invention integrates the water inlet pipeline by improving the water inlet pipeline in the waterway system, thereby simplifying the arrangement of the water pipes in the waterway system. If the L-shaped integrated water box structure 10 is adopted: the water box structure 10 is provided with a ventilation structure 104, and the water box structure 10 is additionally provided with a three-in three-out (four-way) structure; the water inlet gating mode of the multi-barrel washing machine is realized by combining the arrangement of a water valve.
It should be noted that, when only a plurality of water box first flow channels 101 are adopted, on-off switching of water channels and the like can be realized by the gating structure, so that water can be supplied to different washing tubs; when only the water box second flow passage 102 is adopted and is multiple, a water valve can be arranged between the outlet of the water inlet main pipe and the inlet of the water box second flow passage 102, and the water valve is used for controlling the opening and closing of a communication passage from the water inlet main pipe to the washing barrel through the water box second flow passage 102, in this case, the gating structure is not arranged, or the gating control of other liquid (such as detergent) or other water passages is realized through the gating structure; when the water box first flow passage 101 and the water box second flow passage 102 are arranged, the lengths of the water box first flow passage 101 and the water box second flow passage 102 can be combined, the water box first flow passage and the water box second flow passage are adaptively communicated with the washing barrel, and at the moment, the water inlet of the washing barrel can be realized through the two water box flow passages. It can be understood that when the opening and closing of the waterway channel connected with the second flow channel 102 of the water box are controlled, a single water valve can be arranged. The water valve can adopt a solenoid valve or other electric valves and the like.
In some alternatives, the water box structure 10 includes a box body and a box cover covering the box body.
