Description

Technical Field

[0001] This utility model relates to the field of cutlery baskets, and more particularly to an exhaust structure for a dishwasher. Background Technology

[0002] As an essential appliance in modern kitchens, dishwashers automatically wash, dry, and sanitize tableware, greatly improving kitchen efficiency. The internal structure of a dishwasher typically requires an exhaust vent to balance the pressure between the inner drum and the outside environment during the drying phase. Currently, most dishwashers on the market have their exhaust vents located on the top wall. However, the water tank at the top interferes with the exhaust vent, forcing dishwashers with a top water tank to place the exhaust vent on the side. This necessitates modifications to the side structure of the dishwasher to accommodate the exhaust vent.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide an exhaust structure for a dishwasher that solves the problem of interference between the water tank and the exhaust port.

[0005] To achieve the above objectives, this utility model provides a venting structure for a dishwasher, which includes an inner tub, a water tank, and a water tank cover. The water tank is located at the top and side of the inner tub. The top of the water tank is an open structure. An vent is opened at the upper end of the inner tub. The water tank cover seals the top opening of the water tank and has an vent connector that connects to the vent. The vent connector is sealed to the vent. The water tank cover has an air outlet that communicates with the vent connector.

[0006] In one or more embodiments, the upper part of the inner liner is provided with a surrounding wall around the exhaust port, the inner side of the surrounding wall is provided with a sealing ring and a step for supporting the sealing ring, and the exhaust connector is inserted into the surrounding wall and presses the sealing ring.

[0007] In one or more embodiments, the inner liner is provided with two or more connecting posts around the outer side of the enclosure wall, the connecting posts are provided with threaded holes, the exhaust connector is provided with mounting holes corresponding to the threaded holes, and the mounting holes are provided with first screws that are connected and fixed to the threaded holes.

[0008] In one or more embodiments, the water tank cover is fixed to the water tank by a plurality of second screws, and the water tank cover has a water inlet.

[0009] In one or more embodiments, the water tank and the inner liner are integrally formed.

[0010] In one or more embodiments, the top of the inner liner is provided with a casing cover, and the casing cover is provided with a ventilation grille at the position corresponding to the air outlet.

[0011] In one or more embodiments, the inner liner is provided with an air inlet, which is located away from the exhaust port.

[0012] Compared with the prior art, the advantages of this utility model are: by integrating the water tank cover and the vent, the vent connector on the water tank cover is directly and sealed to the vent of the inner tank, which effectively avoids the structural interference problem between the traditional top water tank and the vent. This allows the vent to be flexibly arranged on the top without having to be moved to the side due to water tank occupation, thus simplifying the overall structural layout.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] See appendix Figure 1-2 This application provides a venting structure for a dishwasher, which includes an inner tank 1, a water tank 2, and a water tank cover 3. The water tank 2 is located at the top and side of the inner tank 1. The top of the water tank 2 is an open structure. The upper end of the inner tank 1 has a vent 4, that is, the vent 4 is located in the water tank 2. The water tank cover 3 seals the top opening of the water tank 2 and has a vent connector 5 that mates with the vent 4. The vent connector 5 is sealed to the vent 4 and connects the inside of the inner tank 1 to the outside through the vent connector. The water tank cover 3 has an air outlet 6 that communicates with the vent connector 5, thereby solving the interference problem between the water tank and the vent. The vent connector 5 is provided with a cross rib, which can strengthen the structural strength of the vent connector 5 and prevent its deformation.

[0016] The upper part of the inner tank 1 is surrounded by a wall 7 around the vent 4. The inner side of the wall 7 is provided with a sealing ring 8 and a step 71 for supporting the sealing ring 8. The vent connector 5 is inserted into the wall 7 and presses the sealing ring 8. The vent connector 5 is connected to the wall 7 by an insertion method, that is, it is connected to the vent 4. The sealing effect is further improved by the sealing ring to prevent water in the water tank from entering the inner tank 1 from the connection between the vent connector 5 and the vent 4.

[0017] The inner liner 1 is provided with two or more connecting posts 9 around the outer side of the enclosure 7. The connecting posts 9 are provided with threaded holes. The exhaust connector 5 is provided with mounting holes 10 corresponding to the threaded holes. The mounting holes 10 are provided with first screws that are connected and fixed to the threaded holes. The connection of the first screws can improve the tightness of the connection between the exhaust connector 5 and the exhaust port 4.

[0018] The water tank cover 3 is fixed to the water tank 2 by several second screws. A sealing gasket can be set between the water tank cover 3 and the water tank 2 to improve the sealing effect. The water tank cover 3 has a water inlet 11 so that the user can add water to the water tank 2 through the water inlet 11.

[0019] To further improve the sealing performance between the water tank 2 and the inner liner 1, the water tank 2 and the inner liner 1 are integrally molded, specifically an injection-molded integral structure, which eliminates the need for sealing treatment at the connection between the water tank 2 and the inner liner 1.

[0020] The inner liner 1 is provided with a cover 12 on the top. The cover 12 is provided with a ventilation grille 13 at the position corresponding to the air outlet 6. The ventilation grille 13 can be used for exhaust and can prevent large foreign objects from entering the inner liner from the air outlet.

[0021] The inner liner 1 is provided with an air inlet 14, which is located away from the exhaust outlet 4. The air inlet 14 is used to input hot air for drying tableware. By setting the air inlet 14 away from the exhaust outlet 4, the time that the hot air stays in the inner liner 1 can be extended, and the hot air will not be directly discharged from the exhaust outlet 4 due to the air inlet 14 being too close to the exhaust outlet 4.

[0022] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
