Technical Field
[0001] The utility model relates to the technical field of dishwashers, and more particularly to a dishwasher with an inner tank exhaust structure. Background Art
[0002] During operation, the temperature inside a dishwasher's inner tank is high. Furthermore, the hot air system blows air into the dishwasher, potentially causing air leaks and overflows. Therefore, dishwashers require an exhaust mechanism to partially vent the air inside the dishwasher to balance the air pressure inside the tank.
[0003] In current dishwashers, the inner tank is typically made of metal, while the exhaust structure components are typically made of plastic. An exhaust port is pre-installed on the inner tank surface, and the exhaust structure also has an interface. The exhaust port and interface are connected to each other and sealed with a seal. On the inside of the inner tank, a threaded member is connected to the exhaust structure's structural threads. The threads are tightened to secure the connection, and pressure is applied to the seal to achieve a seal. However, this structural connection is relatively complex, necessitating a new solution to address this issue. Utility Model Content
[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a dishwasher with an inner tank exhaust structure.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] This embodiment discloses a dishwasher with an inner tank exhaust structure. Figure 1 、 Figure 2 As shown, the container comprises an inner liner 1, a bottom shell 2, and a cover 4. The bottom shell 2 is located on the outer wall of the inner liner 1 and is integrally injection-molded with the outer wall of the inner liner 1. The bottom shell 2 has a ring-shaped convex structure and is hollow with an opening. The opening of the bottom shell 2 is covered by the cover 4.
[0028] The bottom shell 2 and the cover 4 are sealed by a seal 6 to maintain the sealing of the connection. A sealing groove 41 is provided on the side of the cover 4 facing the bottom shell 2. The contour of the sealing groove 41 is adapted to the contour of the opening of the bottom shell 2, and the contour of the seal 6 is also adapted.
[0029] Assembled type, the seal 6 is embedded in the sealing groove 41, the edge of the open end of the bottom shell 2 is embedded in the sealing groove 41 and abuts against the seal 6, and the seal 6 is used to achieve pressure sealing at the connection between the bottom shell 2 and the cover body 4; the bottom shell 2 and the cover body 4 are locked and fixed by screws 9.
[0030] Reference Figure 2 、 Figure 3As shown, the outer wall of the inner liner 1 is provided with an exhaust hole 3, which connects the bottom shell 2 and the inner liner 1, allowing air to circulate within the inner liner 1. The cover 4 is provided with an opening 5, which connects the inner cavity of the bottom shell 2, thereby forming a passage that connects the inner liner 1 with the external environment. The bottom shell 2 and the cover 4 together form an exhaust cavity 21, with an air inlet end 22 and an air outlet end 23 at the two ends of the exhaust cavity 21, respectively. The exhaust hole 3 is located opposite the air inlet end 22 of the exhaust cavity 21, and the opening 5 is located opposite the air outlet end 23 of the exhaust cavity 21.
[0031] Reference Figure 4 As shown, a number of air baffles 42 are installed within the exhaust cavity 21. These baffles 42 form a barrier within the exhaust cavity 21, creating gaps between the sides of the air baffles 42 and the sidewalls of the exhaust cavity 21. Exhaust is restricted to the narrow gaps, thus extending the exhaust path of the air within the inner container 1. The air within the inner container 1 is sufficiently cooled during exhaust, allowing moisture exhausted from the dishwasher to condense within the exhaust cavity 21, preventing condensation of water mist at the exhaust point outside the dishwasher.
[0032] Specifically, each air baffle 42 is integrally fixedly connected to the cover body 4 , and each air baffle 42 has an arc-shaped structure. After the cover body 4 is installed with the bottom shell 2 , each air baffle 42 of the cover body 4 can be embedded in the exhaust cavity 21 to form multiple barriers in the exhaust cavity 21 .
[0033] To drain condensed water from the exhaust cavity 21, the exhaust cavity 21 is tilted downward from the outlet end 23 toward the inlet end 22. An inclined surface 24 is formed on the underside of the exhaust cavity 21, with the lower sidewall of the bottom housing 2 serving as the inclined surface 24. The exhaust cavity 21 is recessed downward to form a depression corresponding to the inlet end 22, and is recessed upward to form a depression corresponding to the outlet end 23.
[0034] A plurality of exhaust holes 3 are densely distributed at the position of the air inlet end 22. The plurality of exhaust holes 3 are arranged side by side to form a mesh structure, which can prevent large particles of impurities from being exhausted through the exhaust holes 3. In addition, the exhaust holes 3 are located at the lowest position of the exhaust cavity 21, thereby allowing condensed water in the exhaust cavity 21 to be discharged into the inner tank 1, preventing water accumulation in the exhaust cavity.
[0035] Reference Figure 5As shown, the exterior of the dishwasher is further provided with a housing 10, which can enclose the inner container 1 and the exhaust structure of the dishwasher. A plurality of vent holes 101 are provided at positions corresponding to the housing 10 and the opening 5. The vent holes 101 communicate with the outside environment and allow gases to be exhausted from the dishwasher. Furthermore, a sealing ring 51 is installed outside the opening 5. The sealing ring 51 can abut against the inner side of the housing 10. The sealing ring 51 can seal the housing 10 and the opening 5, preventing moist air from escaping from the opening 5 from entering the gap between the housing 10 and the inner container 1.
[0036] The dishwasher in this embodiment further includes a humidity sensor 7 and an odor sensor 8 . The humidity sensor 7 and the odor sensor 8 both include detection ends, and the detection ends of the humidity sensor 7 and the odor sensor 8 are located in the exhaust cavity 21 .
[0037] The humidity sensor 7 and the odor sensor 8 can detect the air state in the exhaust chamber 21, specifically the humidity and odor in the air.
[0038] Specifically, a suitable installation position is pre-processed on the cover body 4, and the humidity sensor 7 and the odor sensor 8 are both installed on the cover body 4. The detection ends of the humidity sensor 7 and the odor sensor 8 extend into the exhaust cavity 21, so as to obtain information on the air state in the exhaust cavity 21.
[0039] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
