Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a dishwasher dispenser and dishwasher. Background Technology
[0002] With the continuous improvement of the functional structure of household dishwashers and the ongoing enhancement of family living standards, dishwashers have gained increasing recognition and acceptance in the market. The more affordable prices have also made them accessible to ordinary families. Currently, the intelligent dispensing unit used in dishwashers is an upgrade from the existing "two-in-one dispenser" to a "three-in-one dispenser" by adding a cavity for holding dishwashing liquid. The dishwashing liquid cavity has a vent and a dispensing hole. The vent serves two purposes: firstly, it releases gas that escapes from the dishwashing liquid cavity due to internal temperature rise, preventing the formation of positive pressure and the cavity from expanding and bulging; secondly, it introduces air to balance the negative pressure created inside and outside the dishwashing liquid cavity during the peristaltic pump's pumping process, which affects the stability of the pumping flow rate.
[0003] The existing dispenser has an internal ventilation channel and a vent next to the liquid inlet on the front, which connects to the ventilation channel. While this solution solves the problem of air pressure balance within the dispenser's cavity, during the dishwasher wash cycle, high-temperature steam enters the dishwashing liquid chamber through this vent on the front and forms condensate through heat exchange. Over time, the accumulated condensate dilutes the dishwashing liquid, affecting the dishwasher's cleaning performance.
[0004] To address the aforementioned technical issues in the industry, some products have added a flap to the outside of the vent to prevent water splashing and steam from entering, but the actual effect is not good. Other products have added two valves, one inlet and one outlet, to the dispenser housing. Although this solution can solve the problem of condensate entering, it requires a high opening pressure for the valve body. The inlet valve needs to open when the peristaltic pump draws liquid and must remain closed under the pressure of the inner cavity during the washing process. The outlet valve, on the other hand, needs to open when the dishwashing liquid cavity is heated and pressurized, overcoming the pressure of the inner cavity. The control system is more complex and increases costs.
[0005] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0035] The dispenser of dish washer provided by the utility model embodiment, it is equipped with air passage 13 in inside and is communicated with the first function cavity 11 for storing dishwashing liquid by air inlet 131, and the air outlet 132 of the air passage 13 is communicated with the air hole 15 in air gap.When dish washer works, can be discharged by the air passage 13, the air hole 15 of the first function cavity 11 due to internal temperature rise escaping gas, avoid forming internal positive pressure, the phenomenon of cavity expansion bulging appears, in addition, can be introduced by the air hole 15 air, to balance the negative pressure formed in the first function cavity 11 in the process of dishwashing liquid being pumped, influence pumping flow stability.The air hole 15 in the utility model embodiment is arranged in the air gap between the second function cavity 12 and cover 14, when dish washer runs, due to liquid inherent tension characteristic, the air gap is closed by liquid film, to prevent dish washer cavity steam from entering the dispenser through the air hole 15, condensation forms condensate, dilutes the dishwashing liquid in the first function cavity 11, to further can guarantee washing effect.The air gap is closed by liquid film, but can allow air to pass through and enter the air hole 15, to further enter the first function cavity 11, high-pressure gas in the first function cavity 11 can also be allowed to pass through the air hole 15 and liquid film and be discharged to the outside, to balance air pressure.In addition, the utility model cancels the air hole in front of existing dish washer dispenser, and the air hole is arranged in the air gap, and the structure is concealed and reliable, and the appearance is simple.
[0036] To avoid steam from entering air hole 15 accidentally, condensation forms condensate and flows into the first function cavity 11 in air hole 15, as Figure 1 、 Figure 2 、 Figure 4As shown, in one embodiment of this utility model, the vent 15 is located within the vent gap at the top of the flip cover 14, and the opening direction of the vent 15 is downward. Thus, even if a small amount of condensate forms, it will flow out of the vent 15 under gravity and will not enter the first functional chamber 11. Preferably, the diameter of the vent 15 is 1mm, which can simultaneously ensure the air intake and exhaust volume while reducing the amount of water vapor condensation. Further, the vent gap is 0.5mm, resulting in a more stable liquid film. Simultaneously, the vent 15 is concealed within this gap, resulting in a simple appearance.
