Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a door assembly for a cleaning machine and the cleaning machine itself. Background Technology

[0002] After a dishwasher finishes its cycle, it typically needs to expel the high-heat steam generated during the washing process from the washing chamber to dry the dishes and keep the inside of the washing chamber dry.

[0003] Modern built-in dishwashers are installed inside cabinets, with only the front of the door exposed. When expelling hot, humid steam, the exhaust pipe is usually located inside the door and extends downwards to the bottom of the door. The expelled hot, humid steam is located inside the cabinet, which can easily lead to corrosion and damage to the cabinet's wood panels.

[0004] In addition, existing dishwashers have two types of door handles: external handles and hidden handles. External handles can easily cause users to bump into things, while hidden handles disrupt the overall integrity of the front of the dishwasher door and affect the visual experience. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a door assembly for a cleaning machine that can maintain the integrity of the front of the door and facilitate the discharge of steam at a high position to avoid damage to the cabinet, 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 cleaning machine that uses the above-mentioned door components, in view of the current state of the prior art.

[0007] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is as follows:

[0008] A door assembly for a cleaning machine includes a door body and a door handle disposed on the door body. The door handle includes a forearm and a rear arm arranged side by side and extending laterally. The ends of the forearm and the rear arm are connected as one piece by a connecting block. The connecting block is hollow inside to form an air guide chamber that communicates with the washing chamber of the cleaning machine. The bottom wall of the connecting block has an exhaust hole that communicates with the air guide chamber. The door handle is disposed on the door body in a way that allows it to move back and forth. Moving the door handle forward exposes the exhaust hole, and moving it backward conceals the door handle while closing the exhaust hole.

[0009] When venting is needed, move the door handle forward to the front of the door. At this time, the connecting block is exposed in front of the door, thus exposing the vent at the bottom. The hot and humid steam in the washing chamber is discharged through the vent in this high position without damaging the cabinet. After venting is complete, move the door handle backward to hide it, maintaining the integrity of the front of the door and keeping it aesthetically pleasing.

[0010] Preferably, the door body has a horizontally extending and front-to-back through mounting opening, and the door handle is movable and constrained at the mounting opening. When the door handle extends out of the mounting opening, the forearm is located in front of the door body and the rear arm covers the mounting opening.

[0011] In this invention, in the venting state, the forearm is located in front of the door body, the front surface of the rear arm is flush with the front surface of the door body, and the vent holes of the connecting block and its bottom wall are exposed outside the mounting opening; in the non-venting state, the forearm covers the mounting opening and its front surface is flush with the front surface of the door body, and the rear arm, the connecting block and the vent holes on the connecting block are all located inside the door body.

[0012] Preferably, the lower edge of the mounting opening extends rearward to form a support platform. When the door handle is concealed, the bottom wall of the connecting block rests on the support platform, and the vent hole of the bottom wall of the connecting block is sealed by the support platform. With this structure, the vent hole is closed in the non-venting state to prevent steam leakage during washing.

[0013] Preferably, the door body is provided with a drive component capable of driving the door handle to move back and forth, and this drive component is connected to the rear arm of the door handle. This structure facilitates automatic driving of the door handle's back and forth movement.

By pressing the operation key, the user can more precisely control whether the door handle extends or retracts.

[0014] Preferably, the driving component is a push rod motor, the push rod of which extends forward and backward and connects to the rear arm of the door handle. This invention achieves door handle actuation through a push rod motor, resulting in a simple structure and reliable operation.

[0015] Preferably, the connecting block is provided with a slot located inside the air guide chamber and having an open rear end, and the front end of the push rod passes through the open end and is inserted into the slot of the connecting arm. This structure makes the assembly between the drive component and the door handle more compact and stable, thereby improving the reliability of the door handle's forward and backward movement.

[0016] Preferably, the door body is further provided with an exhaust assembly, which includes an exhaust pipe and a fan. The exhaust pipe has an air inlet communicating with the washing chamber of the cleaning machine and an air outlet communicating with the air guide chamber. The fan is located in the exhaust pipe and is used to provide power for exhaust. The above structure is adopted to improve exhaust efficiency.

[0017] Preferably, the exhaust assembly is located below the mounting port, with the exhaust pipe's inlet at the top and its outlet at the bottom. A rear cover is provided on the back of the rear arm to seal the rear end of the air guide chamber. The exhaust pipe's outlet is connected to the air guide chamber via the air guide pipe and the rear cover. A sensor for detecting temperature and humidity is detachably connected to the inner top wall of the rear cover. This structure improves the sealing performance of the exhaust port on the rear arm, preventing steam leakage.

[0018] A cleaning machine includes a housing with an opening, and a door for opening or closing the opening of the housing.

[0019] Preferably, exhaust holes are provided at the bottom of the two connecting blocks between the two ends of the forearm and the rear arm. The air guide tube includes a first part for guiding the airflow and a transverse tube arranged laterally behind the rear arm. The transverse tube is connected to the air guide chamber corresponding to each set of exhaust holes. This structure helps to improve exhaust efficiency.

[0020] Compared with the prior art, the advantages of this utility model are as follows: The door handle of this utility model is provided with a front arm and a rear arm arranged side by side. When venting is required, the door handle is moved forward to the front of the door body.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1-5As shown, the door assembly for the cleaning machine in this embodiment includes a door body 1 and a door handle 2 disposed on the door body 1. The door handle 2 includes a front arm 21 and a rear arm 22 arranged side by side and extending laterally. The ends of the front arm 21 and the rear arm 22 are connected as one unit by a connecting block 23. The connecting block 23 is hollow inside to form an air guide chamber 20 that communicates with the washing chamber of the cleaning machine. The bottom wall of the connecting block 23 is provided with an exhaust hole 200 that communicates with the air guide chamber 20. The door handle 2 is disposed on the door body 1 in a way that allows it to move back and forth. Moving the door handle 2 forward exposes the exhaust hole 200, and moving it backward closes the exhaust hole 200 while hiding the door handle.

[0028] When venting is required, move the door handle 2 forward to the front of the door 1. At this time, the connecting block 23 is exposed in front of the door 1, thus exposing the vent 200 at its bottom. The hot and humid steam in the washing chamber is discharged through the vent 200, which is positioned high, without damaging the cabinet. After venting is completed, move the door handle 2 backward to hide the door handle 2, maintaining the integrity of the front of the door 1 and keeping it aesthetically pleasing.

[0029] The door body 1 has a horizontally extending and front-to-back through mounting opening 11. The door handle 2 is constrained at the mounting opening 11 and can move back and forth. When the door handle 2 extends out of the mounting opening 11, the forearm 21 is in front of the door body 1 and the rear arm 22 covers the mounting opening 11. When the door handle 2 is hidden in the mounting opening 11, the forearm 21 covers the mounting opening 11.

[0030] In this embodiment, in the venting state, the forearm 21 is located in front of the door body 1, the front surface of the rear arm 22 is flush with the front surface of the door body 1, and the vent holes 200 of the connecting block 23 and its bottom wall are exposed outside the mounting opening 11; in the non-venting state, the forearm 21 covers the mounting opening 11 and its front surface is flush with the front surface of the door body 1, and the rear arm 22, the connecting block 23 and the vent holes 200 on the connecting block 23 are all located inside the door body 1.

[0031] The lower edge of the mounting opening 11 extends rearward to form a support platform 12. When the door handle 2 is hidden, the bottom wall of the connecting block 23 is supported on the support platform 12, and the vent 200 of the bottom wall of the connecting block 23 is sealed by the support platform 12. With this structure, the vent 200 is closed in the non-venting state to prevent steam leakage during the washing process.

[0032] The door body 1 is equipped with a drive component 3 that can drive the door handle 2 to move back and forth. This drive component 3 is connected to the rear arm 22 of the door handle 2. This structure facilitates the automatic driving of the door handle 2 to move back and forth. An operation key can also be provided on the outer surface of the forearm 21. This operation key is electrically connected to the drive component 3. By pressing the operation key, the user can more precisely control whether the door handle 2 extends or retracts.

[0033] The driving component 3 is a push rod motor, whose push rod 31 extends forward and backward and connects to the rear arm 22 of the door handle 2. In this embodiment, the door handle 2 is driven by a push rod motor, which has a simple structure and reliable operation.

[0034] The connecting block 23 is provided with a slot 231 located inside the air guide chamber 20 and having a rear end opening. The front end of the push rod 31 passes through the opening and is inserted into the slot 231 of the connecting arm. This structure makes the assembly between the drive component 3 and the door handle 2 more compact and stable, thereby improving the reliability of the door handle 2's forward and backward movement.

[0035] The door body 1 is also equipped with an exhaust assembly 4, which includes an exhaust pipe 41 and a fan 42. The exhaust pipe 41 has an air inlet 411 that communicates with the washing chamber of the cleaning machine and an air outlet that communicates with the air guide chamber 20. The fan 42 is located in the exhaust pipe 41 and is used to provide power for exhaust. The above structure is adopted to improve exhaust efficiency.

[0036] The exhaust assembly 4 is located below the mounting port 11, with the air inlet 411 of the exhaust pipe 41 at the top and the air outlet at the bottom. A rear cover 5 is provided on the back of the rear arm 22 to seal the rear end of the air guide chamber 20. The air outlet of the exhaust pipe 41 is connected to the air guide chamber 20 via the air guide pipe 7 and the rear cover 5. A sensor 6 for detecting temperature and humidity is detachably connected to the inner top wall of the rear cover 5. This structure improves the sealing of the connection at the exhaust port 200 of the rear arm 22, preventing steam leakage.

[0037] Immediately after washing, the temperature and humidity inside the washing chamber are at their highest. Expelling the hot, humid air to a cooler environment at this time easily leads to condensation at the exhaust vents. To reduce condensation, the hot, humid air can be blown at a faster speed to a location farther from the exhaust vent. The temperature drops further away from the vent, allowing the moisture to dissipate into the air, thus reducing the likelihood of condensation. According to Bernoulli's principle, with a constant fan speed, a smaller exhaust vent area allows for a faster airflow, propelling the hot, humid air further. Therefore, in the initial drying stage, a small exhaust vent area minimizes condensation; once the temperature and humidity drop to a certain level, a larger exhaust vent area accelerates drying. The reduced humidity at this stage also prevents condensation. This process is controlled by adjusting the extension distance of the door handle. For example, when the temperature and humidity sensor detects that the temperature and humidity of the exhaust air have reached a threshold, the door handle extends further, increasing the exhaust area and improving the exhaust effect.

[0038] The cleaning machine of this embodiment includes a housing with an opening and a door 1, which is used to open or close the opening of the housing.

[0039] Both connecting blocks 23 between the two ends of the forearm 21 and the rear arm 22 have exhaust holes 200 at their bottoms. The air guide tube 7 includes a first part for guiding the airflow and a transverse tube arranged laterally behind the rear arm 22. The transverse tube is connected to the air guide chamber 20 corresponding to each set of exhaust holes 200. This structure helps to improve exhaust efficiency.

[0040] In this embodiment, the door handle 2 is provided with a front arm 21 and a rear arm 22 arranged side by side. When venting is required, the door handle 2 is moved forward to the front of the door body 1. At this time, the connecting block 23 is exposed in front of the door body 1, and the vent hole 200 at its bottom is exposed. The hot and humid steam in the washing chamber is discharged through the vent hole 200, which is placed in a high position, without damaging the cabinet. After venting is completed, the door handle 2 is moved backward to hide the door handle 2, maintaining the integrity of the front of the door body 1 and keeping it beautiful.
