Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to an exhaust assembly, door structure, and dishwasher for use in a dishwasher. Background Technology

[0002] Dishwashers are devices used to automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, and forks. They can greatly reduce the labor intensity of cooks and improve their work efficiency. With people paying more attention to kitchen hygiene, dishwashers have been widely used in the kitchens of restaurants and ordinary households.

[0003] After cleaning the dishes, the dishwasher needs to expel the moisture from inside the drum to promote the drying of the dishes. Currently, in built-in dishwashers (i.e., front-door dishwashers), the exhaust vent is located on the drum or door. For example, the Chinese utility model patent disclosed in patent application number CN202221536190.5 (publication number CN218074902U) entitled "A Cleaning Machine" includes a housing with a washing chamber inside. The housing has an air inlet and an air outlet that are fluidly connected to the washing chamber. An exhaust pipe has a first end fluidly connected to the air outlet and a second end fluidly connected to the atmosphere, and an air passage is opened in the middle of the exhaust pipe. A pipe body connects the air passage and the air outlet. A baffle is rotatably disposed in the pipe body or the exhaust pipe to connect or block the air passage and the air outlet. The housing includes an inner liner with an open front side and an air inlet on the inner liner. A door is rotatably disposed on the front side of the inner liner. The door can open or close the open side of the inner liner and can form a washing chamber together with the inner liner. An air outlet is opened on the door, and the exhaust pipe extends vertically. In this way, the hot and humid gases in the inner liner will be discharged through the exhaust pipe and flow directly into the atmosphere, rather than remaining between the inner liner and the outer shell. This prevents the condensation generated by the hot and humid gases from contaminating and corroding the cabinet.

[0004] However, as can be seen from the picture, the second end of the exhaust pipe is located on the front side of the box. If the hot air in the washing chamber of the box is directly discharged into the atmosphere, the exhaust port is directly facing the position where the user is standing, which can easily burn the user. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a ventilation component for a dishwasher that can prevent users from being scalded by the exhaust hot airflow, in light of the current state of the technology.

[0006] The second technical problem to be solved by this utility model is to provide a door structure for a dishwasher that uses the above-mentioned exhaust component, in view of the current state of the prior art.

[0007] The third technical problem to be solved by this utility model is to provide a dishwasher that applies the above-mentioned door structure, in view of the current state of the prior art.

[0008] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: an exhaust assembly for a dishwasher, including an exhaust pipe, the exhaust pipe having an air inlet and an air outlet, the air inlet being used to communicate with the washing chamber of the dishwasher, and the air outlet being used to communicate with the outside, characterized in that a component is provided on the exhaust pipe at the air outlet, the component being hollow inside and having an opening, the air outlet of the exhaust pipe extending into the opening, and there being a gap between the exhaust pipe and the opening of the component, and the opening facing the opposite direction to the air outlet.

[0009] Preferably, the component is an arc shape that arches away from the air outlet. The arc shape can guide the airflow from the air outlet to the opening, so as not to affect the exhaust and prevent the user from being burned. In addition, the arc shape can prevent the user from being accidentally scratched or children from bumping into it, thus improving the user's safety.

[0010] Preferably, the component includes a water-absorbing element. Because airflow condenses within the component at low ambient temperatures, and due to the component's arc shape, water droplets accumulate within its curved structure and are ultimately absorbed by the water-absorbing element, preventing condensate from dripping onto the floor and staining it. The dishwasher produces a lot of moisture during hot air expulsion; after the moisture in the subsequent washing chamber is expelled, the hot air further accelerates the drying of condensate. Furthermore, customers typically use the dishwasher again after a period of time, by which time the condensate will have dried, thus achieving a cycle.

[0011] To ensure that the air outlet extends into the component, the air inlet is located near the first end of the exhaust pipe, and a through hole is provided on the side wall of the exhaust pipe near the second end. A flange extends from the periphery of the through hole in a direction away from the exhaust pipe to form the air outlet.

[0012] The two opposite edges of the opening of the component are referred to as the first edge and the second edge, respectively. The first edge can press against the surface of the flange near the first end, and the second edge is located below the second end of the exhaust pipe.

[0013] If the component is only pressed against the flange by the first edge, it may become loose relative to the exhaust pipe. Preferably, the outer wall surface of the side wall opposite the through hole of the exhaust pipe is provided with a rib, and a positioning strip is connected at the second edge. The positioning strip can press against the rib. The positioning strip pressing against the rib, together with the first edge pressing against the flange, makes the component relatively fixed to the exhaust pipe.

[0014] Preferably, the first edge can be detachably pressed against the flange, and the positioning strip can be detachably pressed against the rib. This allows the component to be detachably installed on the exhaust pipe. During installation, the first edge is pressed against the flange first, and then the positioning strip is pressed against the rib. During disassembly, the positioning strip is first removed from the rib, and then the first edge is removed from the flange, making assembly and disassembly convenient.

[0015] In order to allow the positioning strip to be detachably pressed against the rib, the component is a strip extending in the left and right direction, and L-shaped connecting strips are formed at both ends of the second edge. The free ends of the two connecting strips are connected by the positioning strip. When the component is installed on the exhaust pipe, the connecting strip can deflect toward or away from the direction where the flange is located under the action of external force.

[0016] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a door structure for a dishwasher, characterized in that it includes a door and the above-mentioned exhaust assembly, wherein the door is provided with an air inlet for communicating with the washing chamber of the dishwasher, the exhaust pipe is installed on the door, the air inlet of the exhaust pipe is connected to the air inlet of the door, and the air outlet of the exhaust pipe extends out of the door and communicates with the outside.

[0017] The technical solution adopted by this utility model to solve the third technical problem mentioned above is as follows: a dishwasher, characterized in that it includes a cabinet with a front opening and the aforementioned door structure. The door is rotatably disposed at the front opening of the cabinet, thereby opening or closing the door. When the door is closed, the air outlet faces forward and the opening faces backward; when the door is open, the air outlet faces downward and the opening faces upward. When the door is closed, if the user stands in front of the door, the component guides the airflow from the air outlet to the gap between the opening and the exhaust pipe, i.e., the airflow flows backward, preventing burns to the user. When the door is open, condensate in the exhaust pipe flows from the air outlet into the component, preventing it from dripping onto the ground and reducing the risk of slipping on wet surfaces.

[0018] Compared with the prior art, the advantages of this utility model are as follows: By setting a component on the exhaust pipe and inserting the air outlet into the component, the airflow from the air outlet is blocked by the component and will not flow directly onto the user and burn the user. In addition, the opening of the component faces the opposite direction to the air outlet of the exhaust pipe, so the airflow finally flows out from the gap between the opening and the air outlet. That is, the direction of the final airflow is away from the direction of the user, so it will not burn the user. Attached Figure Description

[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0025] like Figures 1-5 As shown, the dishwasher of this preferred embodiment includes a cabinet 1 and a door structure. The cabinet 1 has an open front side, and the door structure includes a door 2 and an exhaust assembly. The door 2 is rotatably disposed at the open front side of the cabinet 1, thereby opening or closing the door 2. The way the door 2 and the cabinet 1 cooperate is the prior art, and will not be described in detail here.

[0026] The exhaust assembly includes an exhaust duct 3 and a component 4. The exhaust duct 3 has an air inlet and an air outlet 31. The air inlet is used to connect with the washing chamber of the dishwasher, and the air outlet 31 is used to connect with the outside. Specifically, the door body 2 is provided with an air inlet hole for connecting with the washing chamber of the dishwasher. The exhaust duct 3 is installed on the door body 2, the air inlet of the exhaust duct 3 is connected with the air inlet hole of the door body 2, and the air outlet 31 of the exhaust duct 3 extends out of the door body 2 to connect with the outside.

[0027] The exhaust pipe 3 has a component 4 at the air outlet 31. The component 4 is hollow inside and has an opening 41. The air outlet 31 of the exhaust pipe 3 extends into the opening 41, and there is a gap between the exhaust pipe 3 and the opening 41 of the component 4 to allow airflow. The opening 41 is opposite to the air outlet 31.

[0028] With door 2 closed, air outlet 31 faces forward and opening 41 faces backward. With door 2 open, air outlet 31 faces downward and opening 41 faces upward. This ensures that when door 2 is closed, if the user stands in front of door 2, component 4 guides the airflow from outlet 31 to the gap between opening 41 and exhaust pipe 3, allowing the airflow to flow backward and preventing burns. When door 2 is open, condensate in exhaust pipe 3 flows from outlet 31 into component 4, preventing dripping onto the ground and reducing the risk of slipping on wet surfaces.

[0029] In this embodiment, component 4 is an arc shape that arches away from the air outlet 31. The arc shape can guide the airflow from the air outlet 31 to the opening 41. This can prevent users from being burned without affecting the exhaust. In addition, the arc shape can prevent users from being accidentally scratched or children from bumping into it, thus improving the safety of users.

[0030] The air inlet of the exhaust pipe 3 is located near the first end of the exhaust pipe 3. A through hole 32 is provided on the side wall of the exhaust pipe 3 near the second end. A flange 33 extends from the through hole 32 in a direction away from the exhaust pipe 3 to form an air outlet 31.

[0031] The two opposite edges at the opening 41 of component 4 are respectively called the first edge 46 and the second edge 42. The first edge 46 can press against the surface of the flange 33 near the first end of the exhaust pipe 3, and the second edge 42 is located below the second end of the exhaust pipe 3.

[0032] The outer wall surface of the side wall opposite to the through hole 32 of the exhaust pipe 3 is provided with a raised rib 43. The second edge 42 is connected to the positioning strip 44, and the positioning strip 44 can press against the raised rib 43. The positioning strip 44 presses against the raised rib 43, and cooperates with the first edge 46 to press against the flange 33, so that the component 4 is relatively fixed on the exhaust pipe 3.

[0033] In addition, the first edge 46 is detachably pressed against the flange 33, and the positioning strip 44 is detachably pressed against the rib 43. In this way, the component 4 can be detachably installed on the exhaust pipe 3. During installation, the first edge 46 is pressed against the flange 33 first, and then the positioning strip 44 is pressed against the rib 43. During disassembly, the positioning strip 44 is first removed from the rib 43, and then the first edge 46 is removed from the flange 33. The assembly and disassembly are convenient.

[0034] In this embodiment, the component 4 is a strip extending in the left and right direction. L-shaped connecting strips 45 are formed at both ends of the second edge 42. The free ends of the two connecting strips 45 are connected by the positioning strip 44. When the component 4 is installed on the exhaust pipe 3, the connecting strips 45 can deflect toward or away from the flange 33 under the action of external force, so that the positioning strip 44 can press against or detach from the rib 43.

[0035] Additionally, component 4 includes a water-absorbing element 5, which can be made of sponge. When the ambient temperature is low, the airflow will condense within component 4. Due to the curved shape of component 4, water droplets will gather within its curved structure and be absorbed by the water-absorbing element 5, preventing condensate from dripping onto the floor and staining it. The dishwasher produces a lot of moisture when expelling hot air; after the moisture in the subsequent washing chamber is expelled, the hot air further accelerates the drying of the condensate. Furthermore, customers typically use the dishwasher again after a period of time, by which time the condensate will have dried, thus achieving a cycle.

[0036] Because the center of gravity of component 4 is at the arc, when door 2 is opened, component 4 will not fall off the exhaust pipe 3, but will hang stably on the exhaust pipe 3. Figure 3 As shown.

[0037] When door 2 is closed, as Figure 4 As shown, the water accumulated in component 4 will flow back to the water-absorbing component 5 and be absorbed, thus entering the next cycle.
