Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a door structure for a dishwasher and the dishwasher. Background Art

[0002] At present, dishwashers are widely used in home kitchens. Generally, after the washing process is completed, a large amount of water and water vapor will remain inside the dishwasher cavity (basket, tableware, liner, bottom, etc.). During the drying process, the high-temperature hot air will take out the water vapor and discharge it into the air. The exhaust duct outlet is generally set on the lower side of the door body, facing the front. Due to the lower temperature outside, the high-temperature and high-humidity gas will quickly condense in the duct and the pipe mouth, forming water beads or water droplets. Some of them will evaporate with the hot air, and some will drip onto the ground or cabinets, causing a poor user experience.

[0003] In response to the above problems, the Chinese utility model patent with patent number CN202221126127.4 (publication number CN217852838U) discloses "Exhaust tail pipe for cleaning machine and cleaning machine". The exhaust tail pipe includes a longitudinally extending exhaust pipe, the interior of which is hollow to form an exhaust channel, the lower end of the exhaust pipe is bent horizontally to one side to form a water storage tank for storing condensed water, and the side wall of the exhaust pipe is provided with an exhaust port located above the water storage tank and connected to the exhaust channel and the water storage tank. The utility model sets a water storage tank at the lower end of the exhaust pipe. During the downward transportation of the high-temperature gas with moisture, the condensed water formed is stored in the water storage tank, and other steam is discharged through the exhaust port. The accumulated water temporarily stored in the water storage tank is continuously evaporated and dried under the high temperature of the steam, and there is no need to discharge the accumulated liquid. This not only solves the problem of condensed water dripping at the outlet, but is also very convenient to use.

[0004] This patent requires processing the exhaust end of the exhaust tail pipe and designing a water tank, which is rather troublesome. Moreover, the size of the water tank designed in the exhaust tail pipe is affected by the size of the air flow channel inside the exhaust tail pipe, and the water storage capacity of the water tank is also very limited. If there is a lot of condensed water, it is easy to overflow from the exhaust tail pipe and drip onto the ground. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a door structure for a dishwasher with a large water storage capacity in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a dishwasher using the above-mentioned door structure in view of the current status of the prior art.

[0007] The utility model solves the above-mentioned first technical problem by adopting a technical solution: a door structure for a dishwasher, comprising:

[0008] The door body is used to be connected to the cabinet of the dishwasher so as to be flippable forward and backward, and the door body is provided with an exhaust port;

[0009] An exhaust pipe is installed on the door body, and the exhaust pipe is provided with an air inlet and an air outlet connected to the interior thereof, the air inlet and the air outlet are connected, and the air outlet is connected to the outside;

[0010] It is characterized by that it also includes

[0011] The water absorption box has an open top and is installed on the exhaust pipe. When the door body rotates, a relative displacement occurs between the water absorption box and the exhaust pipe, and the air outlet is always located directly above the water absorption box.

[0012] Preferably, when the door is closed, the air outlet faces forward and discharges the air out of the cabinet; when the door is open, the air outlet faces downward, facing the water absorption box, and the condensed water accumulated in the exhaust pipe can be poured into the water absorption box.

[0013] In order to make the water suction pipe and the exhaust pipe produce relative displacement when the door body is rotating, an arc-shaped hanging ring is provided on the exhaust pipe. When the door body is closed, the two ends of the hanging ring are respectively located at the upper and lower sides of the air outlet, and the hanging ring is an arc-shaped structure that arches away from the air outlet.

[0014] The water absorption box is provided with a hook hung on the hanging ring, and the hook can slide along the hanging ring. When the door is opened, the hook will slide along the hanging ring without affecting the rotation of the door, and the condensed water in the exhaust pipe will also pour into the water absorption box; when the door is closed, the hook will slide freely along the hanging ring and return to the initial state.

[0015] In order to improve the stability of the water absorption box relative to the exhaust pipe, the hanging ring has two spaced apart in the left and right directions, and correspondingly, there are two hooks, which are hung on the hanging rings one by one. In this way, both the left and right sides of the water absorption box are connected to the exhaust pipe, and the stability is good.

[0016] Preferably, the vertical section can be deflected in a direction away from the corresponding hanging ring under the action of an external force, so that the transverse section can be disengaged from the hanging ring. In this way, the water absorption box is detachably connected to the exhaust pipe, and the water absorption box can be removed if the water absorption box needs to be replaced or is no longer needed.

[0017] The hook can have a variety of structural forms, and the structure is simple. The hook is L-shaped, including a vertical section extending vertically and a transverse section connected to the upper end of the vertical section. The lower end of the vertical section is connected to the top wall of the water absorption box, and the transverse section extends in the left and right directions. The transverse section is passed through the hanging ring.

[0018] In order to further increase the water storage capacity of the water absorption box, a water absorption member is provided in the water absorption box. The water storage capacity of the water absorption member is large and can prevent condensed water from spilling out of the water absorption box during the opening and closing of the door. The water absorption member can be detachably laid flat on the bottom wall of the water absorption box and can be replaced, and is highly convenient to use.

[0019] In the above scheme, the exhaust pipe includes a tube body and a convex portion extending from the side wall of the lower part of the tube body, the extension direction of the convex portion is perpendicular to the extension direction of the tube body, the air inlet is opened on the tube body, and the tube body is installed on the door body, and the air outlet is opened on the wall surface of the convex portion facing away from the tube body.

[0020] In order to prevent the water absorption box from shaking and causing water to spill, a limiting groove with an open top and rear side is provided on the rear side wall of the water absorption box. When the door is closed, the portion of the front side wall of the tube body located under the convex portion abuts against the rear wall of the limiting groove, and the water absorption box cannot swing backward.

[0021] In order to make the water absorption box counteract the limiting part, when the door body is closed, the part of the front side wall of the tube body located below the convex part is called the limiting part, and a counterweight block is provided on the water absorption box. When the door body is closed, the water absorption box maintains the state of the limiting groove counteracting the limiting part under the action of the counterweight block.

[0022] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a dishwasher, characterized in that it includes a box body and the above-mentioned door body structure, the front side of the box body is open, the lower part of the door body can be rotatably connected to the box body, so that the door body can be flipped forward and backward relative to the box body, and the exhaust port on the door body is connected to the inside of the box body.

[0023] Compared with the prior art, the utility model has the following advantages: the utility model is provided with a water absorption box, and the water absorption box is located outside the air flow channel of the exhaust pipe, so that the size of the water absorption box is not limited by the size of the air flow channel of the exhaust pipe, and can be made larger, with a large water storage capacity; in addition, relative displacement can occur between the water absorption box and the exhaust pipe, and the water absorption box is always located directly below the air outlet, and condensed water formed at the air outlet can drip into the water absorption box under the action of gravity; in addition, the air outlet is always located directly above the water absorption box. During the drying process of the dishwasher, the hot air discharged from the air outlet is located above the water absorption box, which accelerates the evaporation of water in the water absorption box and circulates all the time without the need for replacement, and is beautiful, safe and reliable.
