Description

Water tank ventilation structure and dish washer Technical Field The utility model relates to the field of dish washers, in particular to a water tank ventilation structure and a dish washer. Background The water tank of the traditional dish washer generally adopts a closed design, and is mainly used for adjusting the water quantity by means of a mechanical valve or adjusting the air pressure by means of a pressure relief hole communicated with the outside so as to adapt to the situation that the water injection quantity is abnormally increased or the air pressure is abnormally increased. However, the pressure relief mode is easy to cause the problem that excessive water flow and air pressure cannot be released in time due to channel blockage to cause deformation or even burst of the water tank, so that the service life of a product is influenced, and the safety of equipment is also influenced. Disclosure of utility model Based on this, it is necessary to provide a ventilation structure of a water tank and a dishwasher, which are necessary to solve the problem that the water tank is deformed or burst due to the fact that too much water flow and air pressure cannot be released in time because of the blockage of a channel in the pressure release mode of the water tank of the conventional dishwasher. The water tank ventilation structure comprises a liner assembly, a water tank assembly and a locking assembly, wherein the liner assembly is provided with a washing cavity, the water tank assembly is arranged on the liner assembly and is provided with a liquid storage cavity, the water tank assembly is provided with an overflow port communicated with the liquid storage cavity and is provided with a flow passage communicated with the overflow port, the locking assembly is arranged on the liner assembly and/or the water tank assembly and is used for connecting the liner assembly and the water tank assembly, and the locking assembly is provided with an output port, and the flow passage, the output port and the washing cavity are sequentially communicated. The first aspect of the application discloses a ventilation structure of a water tank, which is sequentially communicated with a liquid storage cavity, an overflow port, an overflow channel, an output port and a washing cavity to form a stable pressure relief path, so that compressed air of a water tank assembly when liquid is injected into the washing cavity can be transmitted into the washing cavity through the pressure relief path, the explosion of the water tank assembly caused by overlarge air pressure is avoided, and the pressure relief path is not blocked due to the influence of external dust and other factors. The design can also enable excessive water flow to be conveyed into the washing cavity from the pressure release path, so that the explosion of the water tank assembly caused by excessive liquid quantity is avoided, the service life of a product is effectively prolonged, and the safety performance of equipment is better. The inner container assembly and the water tank assembly can be connected together through the locking assembly, and the stability and the firmness of the inner container assembly and the water tank assembly are good. And the locking component is provided with an output port which enables air flow and liquid to be conveyed into the washing cavity, so that the locking component has the dual functions of fixing the structure and guiding air, and does not need to additionally arrange a part for outputting the liquid, thereby optimizing the space utilization rate. In one embodiment, the liner assembly is provided with an opening, the opening is located in the extending direction of the flow passage, the opening is respectively communicated with the flow passage and the output port, and the locking assembly is arranged on the liner assembly and located at the opening. Through the opening respectively with overflow channel and delivery outlet intercommunication for the liquid in the overflow channel can be smooth and easy pass the casing entering into the washing chamber of inner bag subassembly, guarantees the stability of pressure release process. The opening is positioned in the extending direction of the through-flow channel, so that the conveying distance from the liquid in the liquid storage cavity to the washing cavity is shortened, and the practicality is good. In one embodiment, the water tank assembly is provided with a sealing groove, and further comprises a sealing member, wherein the sealing member is arranged on the liner assembly and/or the water tank assembly and is positioned at the sealing groove, the sealing member is positioned between the liner assembly and the water tank assembly, and the sealing member is used for sealing a gap between the liner assembly and the water tank assembly. Through the setting of sealing member sealed space between inner bag subassembly and the water tank subassembly, avoid liquid to leak from
