Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, and in particular to a method for discharging cabinet steam of an embedded dishwasher. Background Art

[0002] At present, the drying methods of built-in dishwashers on the market are mainly PTC hot air blowing, natural exhaust or fan exhaust drying. For the PTC hot air blowing method, during the washing process of the dishwasher, the washing water of the dishwasher is usually heated and produces water vapor. Since the PTC hot air blowing channel is connected to the inner cavity of the dishwasher, the water vapor will be discharged into the narrow gap between the top of the dishwasher and the cabinet through the breathing port of the respirator and the PTC hot air blowing channel, forming condensed water on the inner surface of the cabinet, which will seriously cause the cabinet to mold and damage; and for the natural exhaust or fan exhaust drying method, due to the influence of the exhaust port area and the exhaust channel resistance, the exhaust efficiency is relatively low, affecting the drying effect.

[0003] In addition, for front-loading dishwashers, since the washing water is heated during the washing process and produces high-temperature steam, when the door is opened after cleaning, the high-temperature and humid air will rush in, easily causing burns to the user, seriously reducing the user experience. Summary of the invention

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 6 As shown, the cabinet steam exhaust method of the built-in dishwasher of this embodiment is mainly applicable to the built-in front-opening dishwasher. The dishwasher comprises a cabinet 1 and a door 2. The cabinet 1 is embedded in the cabinet 10 and there is a gap 100 between the top of the cabinet 10 and the inner top wall of the cabinet 10. The cabinet 1 has a front opening. The lower edge of the door 2 is rotatably connected to the lower edge of the front side of the cabinet 1, and is used to open or close the front opening of the cabinet 1.

[0027] An exhaust assembly 3 is provided in the gap 100, and the exhaust assembly 3 has an inlet 31 connected to the gap 100 and an outlet 32 ​​located at the front edge of the cabinet 10. The exhaust assembly 3 is provided with a first air suction port 301 arranged corresponding to the top edge of the door body 2. A second air suction port 302 for sucking air at the front edge of the cabinet 10 is provided on the side wall of the exhaust assembly 3. The second air suction port 302 is located in the gap 100 and is arranged near the front end of the gap 100. The first air suction port 301 and the second air suction port 302 clamp the front edge of the top of the box body 1.

[0028] After cleaning, the exhaust assembly 3 is turned on, and the air carrying water vapor in the gap 100 is sucked in through the inlet 31 and discharged through the outlet 32; 3 seconds after the exhaust assembly 3 is turned on, the door body 2 opens the front side to open a top gap 200, and the front-to-back width of the top gap 200 is 10mm to 100mm. The high-temperature steam in the box body 1 is sucked in through the first air suction port 301 and discharged through the outlet 32. At the same time, the steam overflowing to the top edge of the cabinet 10 is sucked in through the second air suction port 302 and discharged through the outlet 32. The first air suction port 301 is mainly used to quickly discharge the mainstream steam at the top gap 200 of the box body 1, and the setting method and position of the second air suction port 302 and the first air suction port 301 can be used to solve the problem that high-temperature and high-humidity steam diffuses quickly and easily condenses at the top edge of the cabinet, avoiding the formation of condensed water at the top edge of the cabinet.

[0029] In this embodiment, when the door body 2 opens the front side to form a top gap 200, the exhaust assembly 3 covers the top gap 200, and the first air suction port 301 is provided on the lower surface of the exhaust assembly 3 and arranged corresponding to the top gap 200. With such a structure, the exhaust assembly 3 can prevent the steam from being transported upward and rushing toward the user or entering the cabinet 10 in large quantities, and quickly and timely suck it out through the first air suction port 301.

[0030] The exhaust assembly 3 includes a centrifugal fan 33 and an exhaust body 34. The centrifugal fan 33 is arranged in the gap 100 and corresponds to the rear of the box body 1. The air inlet of the centrifugal fan 33 constitutes the inlet 31. The exhaust body 34 is located at the front side of the centrifugal fan 33 and is connected to the air outlet of the centrifugal fan 33. The exhaust body 34 is provided with an exhaust duct 341 extending from the back to the front, and the front end of the exhaust duct 34 constitutes the outlet 32. This structure can discharge the water vapor in the assembly gap at the top of the cabinet 10 to prevent the steam from condensing on the top of the cabinet and causing damage to the cabinet.

[0031] The exhaust body 34 includes an air expansion section 342 gradually extending from the front air outlet of the centrifugal fan 33 to both sides, and an air guide section 343 connected to the air expansion section 342 and located in front of the air expansion section 342. The thickness of the front part of the air guide section 343 is less than the thickness of the air expansion section 342. This structure is conducive to improving the suction wind pressure and wind speed, thereby increasing the negative pressure at the first air suction port 301, and further improving the exhaust efficiency of the first air suction port 301 for high-heat and high-humidity steam. The bottom wall of the rear part of the air guide section 343 connected to the air expansion section 342 gradually tilts upward from the back to the front to form an air guide slope 3431. This structure is conducive to increasing the wind speed and reducing noise.

[0032] The air inlet of the centrifugal fan 33 is located on the top wall thereof, and is arranged corresponding to the inner top wall of the corresponding cabinet 10. Arranging the air inlet of the centrifugal fan 33 toward the inner top wall of the cabinet is conducive to quickly sucking away the steam and avoiding condensation of water vapor on the inner top wall of the cabinet.

[0033] The exhaust body 34 is provided with a plurality of partitions 35 arranged at intervals and extending forward and backward, and the partitions 35 divide the exhaust air duct 341 into a plurality of relatively independent ones. The above structure can play a good role in rectifying and guiding the air transported from the back to the front, thereby improving the suction effect of the first suction port 301 and the second suction port 302 to form a negative pressure.

[0034] The first air suction port 301 extends from top to bottom toward the front opening of the cabinet 1. The angle between the air suction direction of the first air suction port 301 and the mainstream exhaust direction in the exhaust assembly 3 is a, and a=20°~60°. The second air suction port 302 extends from back to front along its air suction direction. The angle between the air suction direction of the second air suction port 302 and the mainstream exhaust direction in the exhaust assembly 3 is b, and b=20°~60°. The above structure is conducive to improving the air suction effect; the second air suction port 302 is arranged with the incoming wind direction toward the inside of the cabinet 10, which can avoid interference with the first air suction port 30 and compete for steam suction and exhaust at the top opening.

[0035] In this embodiment, a door lock assembly is provided on the top of the box body 1 for locking the door body 2 and the box body 1 when the door is closed and for pushing the door body 2 open relative to the box body 1 to form a top gap 200 when the door is opened.

[0036] In the present embodiment, an exhaust assembly 3 is arranged in the installation gap 100 between the top of the box body 1 and the cabinet 10. The exhaust assembly 4 can discharge the air with steam in the assembly gap 100 in the cabinet 10 from the back to the front. During the exhaust process, a negative pressure is formed at the first exhaust air intake port 301 and the second exhaust air intake port 302. At this time, the door body 2 is first opened relative to the box body 1 to form a top gap 200. The first air intake port 301 can be used to discharge the high-temperature and high-humidity steam in the box body 1, and the second air intake port 302 can be used to discharge the steam overflowing to the top edge of the cabinet to prevent it from overflowing into the cabinet 10, thereby avoiding cabinet losses and improving user experience.
