Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically a cold air drying dishwasher. Background Technology

[0002] Traditional dishwashers typically require a drying section at the dish outlet to dry the washed dishes, increasing efficiency and achieving the goal of drying them immediately after removal. However, this drying section occupies space, increasing the overall footprint of the dishwasher. In confined spaces, this makes installation impossible. Furthermore, the drying section consumes significant energy, requiring high power to operate. If the installation site cannot provide sufficient power, the dishwasher cannot be used. Utility Model Content

[0003] Given that existing technologies have the problem that the drying section occupies a large area and requires a large amount of power to drive the operation, and that dishwashers cannot be installed if the space is small or cannot provide a large amount of power, this utility model provides a cold air drying dishwasher.

[0004] This utility model provides a cold air drying dishwasher, including a washing mechanism, a dish conveying mechanism passing through the washing mechanism, at least one cooling fan disposed in the washing mechanism, and a cold air collection cover covering the at least one cooling fan.

[0005] The cold air collection hood has a cold air circulation channel for circulating the cold air emitted by the cooling fan. The air outlet of the cold air circulation channel is provided with an air knife for controlling the air outlet angle. The air knife is directly facing the bowl on the output side of the bowl conveying mechanism.

[0006] Furthermore, the air knife includes a housing fixedly installed with the air outlet of the cold air circulation channel, an air inlet disposed on the side of the housing near the air outlet of the cold air circulation channel, and a blade lip disposed at the air outlet position of the air knife. The blade lip and the air outlet of the air knife form an air outlet gap for blowing out cold air, and the air blowing through the air outlet gap is directed towards the bowls on the bowl conveying mechanism.

[0007] Furthermore, the blade is tilted away from the washing mechanism, and the tilt angle of the blade is 10 to 15 degrees.

[0008] Furthermore, the cold air collection hood is connected to the outer shell of the dryer, the cooling fan is completely covered inside the cold air collection hood, and the cold air collection hood extends above the dish conveying mechanism.

[0009] Furthermore, the cold air circulation channel is inverted L-shaped, and the cold air circulation channel includes a horizontal section parallel to the cooling fan and a vertical section perpendicular to the dish conveying mechanism; the vertical section is close to the outer wall of the washing mechanism.

[0010] Furthermore, the corners of the cold air circulation channel are provided with rounded corners to facilitate the flow of cold air.

[0011] Furthermore, the air knife is configured to have three units.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model patent is based on the principle that a dishwasher's heat recovery system requires a cooling fan to expel a large amount of cold air to achieve heat exchange, using this high volume of cold air to quickly dry the dishes. By installing a cold air collection hood outside the cooling fan to collect the blown cold air, the cold air blown by the cooling fan flows through a cold air circulation channel within the collection hood. Furthermore, by installing air blades at the air outlet of the cold air circulation channel to control the airflow angle, the cold air is directed directly at the dishes on the dish conveyor mechanism for targeted drying. This structure reuses the cold air emitted by the cooling fan, uses the cold air circulation channel to quickly dry the washed dishes, and then uses the dish conveyor mechanism to continuously dry the dishes. This allows for drying of washed dishes with reduced power consumption, saving energy and achieving energy conservation and emission reduction. In addition, it reduces the dishwasher's footprint, enhancing its practicality. It can also be used to modify existing dishwashers without a dryer to improve the drying effect on dishes.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Example 1:

[0024] Please refer to Figures 1-3 This utility model provides a cold air drying dishwasher, including a washing mechanism 1, a bowl inlet 2 and a bowl outlet 3 disposed on both sides of the washing mechanism 1, a dish conveying mechanism 4 passing through the washing mechanism 1, at least one cooling fan 5 disposed in the washing mechanism 1, and a cold air collection cover 6 covering the at least one cooling fan 5.

[0025] Furthermore, the cold air collection cover 6 has a cold air circulation channel 61 for circulating the cold air dissipated by the cooling fan 5. The outlet of the cold air circulation channel 61 is provided with an air knife 62 for controlling the air outlet angle. The air knife 62 is directly opposite the bowl on the input side of the bowl conveying mechanism 4.

[0026] To further explain, the cold air collection cover 6 is installed in conjunction with the outer shell of the dryer, the cooling fan 5 is completely enclosed inside the cold air collection cover 6, and the cold air collection cover 6 extends above the dish conveying mechanism 4.

[0027] This embodiment features a cold air collection hood 6 outside the cooling fan 5 of the washing mechanism 1, which collects the blown cold air. The cold air from the cooling fan 5 flows through a cold air circulation channel 61 within the hood 6. An air knife 62, with adjustable blowing angle, is installed at the outlet of the cold air circulation channel 61, allowing the cold air to be directed directly at the dishes on the dish conveyor mechanism for targeted drying. This structure reuses the cold air emitted by the cooling fan 5. The cold air circulation channel 61 dries the washed dishes, and the dish conveyor mechanism 4 provides continuous drying. This allows for drying of washed dishes with reduced power consumption, saving energy and achieving energy conservation and emission reduction. Furthermore, it reduces the dishwasher's footprint and enhances its practicality.

[0028] In this embodiment, two cooling fans 5 are provided. A cold air collection cover 6 is installed on the outside of one of the cooling fans 5 near the bowl inlet 2. The cold air collection cover 6 collects the waste cold air emitted by the cooling fan 5, allowing the cold air to circulate in the cold air channel and finally blown out from the air knife 62 to dry the bowls located on the bowl conveying mechanism 4. The bowls on the conveying mechanism 4 are continuously dried by conveying, and the bowls dried by the cold air are sent to the storage tank for storage or direct use by the transmission of the bowl conveying mechanism 4. This structure can save the setting of a drying section, greatly reduce power consumption, and make the dishwasher applicable to places with low power, thus enhancing the performance of the dishwasher.

[0029] Furthermore, the cold air collection cover 6 can collect and reuse the exhaust cold air blown out of the cooling fan 5, thereby enhancing the energy utilization rate, reducing the energy loss rate, and achieving the goal of energy conservation, emission reduction, and full utilization of energy.

[0030] To further explain, the dish conveying mechanism 4 transports the dishes from the inlet 2 into the washing mechanism 1 for washing, and then the clean dishes are conveyed out from the outlet 3. The air outlet of the cold air circulation channel 61 is directed at the washed dishes conveyed on the dish conveying mechanism 4, and the cold air in the cold air circulation channel 61 dries the washed dishes. Cold air drying can significantly reduce the overall power consumption of the dishwasher and reduce the overall footprint of the dishwasher, making it suitable for environments with limited space and expanding the applicability of the dishwasher.

[0031] like Figure 2As shown, the air knife 62 includes a housing 621 fixedly installed with the air outlet of the cold air circulation channel 61, an air inlet 622 disposed on the side of the housing 621 near the air outlet of the cold air circulation channel 61, and a blade lip 623 disposed at the air outlet position of the air knife 62. The blade lip 623 and the air outlet of the air knife 62 form an air outlet gap 624 for blowing out cold air. The air blowing through the air outlet gap 624 is directed towards the bowls on the bowl conveying mechanism 4.

[0032] In this embodiment, cold air flows into the air inlet 622 of the air knife 62 through the cold air circulation channel 61, and then blows out through the air outlet gap 624 to dry the washed bowls on the bowl conveying mechanism 4 with cold air.

[0033] Furthermore, the blade lip 623 can control the angle at which the cold air blows towards the bowl, allowing for targeted drying of the bowl. The air outlet gap 624 can also enhance the intensity of the cold air, thereby accelerating the drying speed of the bowl.

[0034] Furthermore, the blade lip 623 is tilted away from the washing mechanism 1, which increases the range of cold air drying, allowing the cold air to dry more bowls on the dish conveying mechanism 4. The tilt angle of the blade lip 623 is 10 to 15 degrees, which allows for more targeted cold air drying of the bowls.

[0035] To further explain, the air blades 62 are set to 3, which is more economical and practical while still meeting the requirement of rapid drying.

[0036] like Figure 1 As shown, the cold air circulation channel 61 is an inverted L-shape. The cold air circulation channel 61 includes a horizontal section 611 parallel to the cooling fan 5 and a vertical section 612 perpendicular to the dish conveying mechanism 4. The vertical section 612 is close to the outer wall of the dryer casing.

[0037] Furthermore, the corner of the cold air circulation channel 61 is provided with a rounded corner 613 to facilitate the circulation of cold air.

[0038] In this embodiment, the waste cold air is blown out from the diffuser fan and hits the inner wall of the horizontal section 611, flowing into the horizontal section 611. When the cold air flows to the end of the horizontal section 611, since the corner position is set at the rounded corner 613, the cold air can flow smoothly from the horizontal section 611 to the vertical section 612, and then blown out from the air knife 62 set at the end of the cold air flow channel 61 to dry the bowls on the bowl conveying mechanism 4 with cold air.

[0039] Example 2:

[0040] like Figure 2As shown, the difference between Embodiment 2 and Embodiment 1 is that the cold air collection cover 6 is installed outside all the cooling fans 5, which can collect all the waste cold air emitted by the cooling fans 5, so that the dishes can be dried with stronger cold air. Without the traditional dryer, all the waste cold air emitted by the cooling fans 5 is reused, which reduces the overall power consumption of the dishwasher and reduces the footprint of the dishwasher. This makes the dishwasher suitable for various site conditions, enhances the practicality of the dishwasher, and achieves the purpose of energy saving, emission reduction and energy reuse.

[0041] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
