Description

Technical Field

[0001] This utility model belongs to the field of dishwasher technology, specifically relating to a cold air outlet duct and a dishwasher. Background Technology

[0002] Dishwashers or sterilizers are installed in the washing and sterilization room. Since the equipment generates a lot of heat during operation, the heat can be recovered by the waste heat recovery equipment to heat the water, while the fan blows out cold air.

[0003] In existing technologies, cold air is typically discharged outdoors through a duct, and the fan outlet needs to be connected to the duct, which is inconvenient for workers to install on-site, and the cold air is not effectively utilized. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where workers need to connect the air outlet of the fan to the duct on-site and the cold air is not effectively utilized. This invention provides a cold air outlet duct and dishwasher that do not require connection to the cold air duct and can effectively utilize the cold air.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A cold air outlet duct, characterized in that: it includes a horizontal duct and a vertical duct that are interconnected, the horizontal duct is provided with a forward air outlet and an upward air outlet, the side wall of the vertical duct is provided with a side air outlet, the lower end of the vertical duct is a lower air outlet, and an air baffle plate rotatably connected to the inner wall of the vertical duct is provided between the side air outlet and the lower air outlet.

[0007] Furthermore, the baffle plate is installed below the side air outlet, and a magnetic block is provided above the side air outlet. The baffle plate is rotated upward and the magnetic block is used to seal the side air outlet.

[0008] Furthermore, the inner wall of the vertical air duct has a limiting member. When the baffle plate rotates downward to near the horizontal position, the baffle plate overlaps the limiting member, and the baffle plate closes the lower air outlet.

[0009] Furthermore, a first knob is installed at the end of the rotating shaft of the windbreak plate, and the first knob is located on the outside of the vertical air duct.

[0010] Furthermore, at least one row of air blades is installed at the lower air outlet.

[0011] Furthermore, the air knife is rotatably mounted on the side wall of the vertical air duct.

[0012] Furthermore, a second knob is installed at the end of the air knife shaft, and the second knob is located on the outside of the vertical air duct.

[0013] Furthermore, it is equipped with multiple forward air outlets and upward air outlets, each of which is individually controlled to open or close via a switch valve.

[0014] Furthermore, the central axes of a forward air outlet and an upward air outlet intersect, and the upward airflow or forward airflow or both the upward air outlet and the forward air outlet are closed by a reversing valve.

[0015] The present invention also discloses a dishwasher, including a washing and disinfection device and a cold air outlet duct disposed above the washing and disinfection device; the lower air outlet is directed to the tableware at the outlet end of the washing and disinfection device to expedite the drying of the tableware with cold air.

[0016] The beneficial effects of this utility model of a cold air outlet duct and dishwasher are:

[0017] Depending on the height of the washing and disinfection room and other site conditions, the cold air outlet duct can be configured to exhaust air upwards or forwards. Workers only need to adjust the valves at the upward and forward exhaust vents after installation. Adjusting the angle of the baffle plate allows for either side-blowing or downward-blowing. Side-blowing can cool the workers washing dishes, while downward-blowing can accelerate the drying of the clean dishes. Attached Figure Description

[0025] 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.

[0026] like Figures 1-5 The dishwasher of this utility model shown includes a washing and disinfection device 15, a waste heat recovery device 8 disposed above the washing and disinfection device 15, and a cold air outlet duct. The waste heat recovery device 8 absorbs the heat from the inlet and outlet of the dishwasher for heat recovery, and the outlet of the fan 14 of the waste heat recovery device 8 is connected to the cold air outlet duct.

[0027] The cold air duct includes an interconnected horizontal duct 1 and a vertical duct 2. The horizontal duct 1 has a forward air outlet 3 and an upward air outlet 4. The side wall of the vertical duct 2 has a side air outlet 5, and the lower end of the vertical duct 2 has a downward air outlet 6. A baffle plate 7, rotatably connected to the inner wall of the vertical duct 2, is installed between the side air outlet 5 and the downward air outlet 6. The side airflow can cool the workers washing dishes, while the downward airflow can accelerate the drying of the clean dishes.

[0028] The baffle plate 7 is installed below the side air outlet 5, and a magnetic block 9 is provided above the side air outlet 5. By rotating the baffle plate 7 upward, it is magnetically attracted to the magnetic block 9 to close the side air outlet 5. The inner wall of the vertical air duct 2 has a limiting member 10. When the baffle plate 7 is rotated downward to near the horizontal position, the baffle plate 7 overlaps with the limiting member 10, and the baffle plate 7 closes the lower air outlet 6.

[0029] To facilitate the rotation of the air baffle 7, a first knob 11 is installed at the end of the rotating shaft of the air baffle 7. The first knob 11 is located on the outside of the vertical air duct 2.

[0030] To ensure precise airflow to the tableware, at least one row of air blades 12 is installed at the lower air outlet 6. The air blades 12 are rotatably mounted on the side wall of the vertical air duct 2 to adjust the airflow angle. For ease of operation, a knob is installed at the end of the rotating shaft of the air blade 12, and the knob is located on the outside of the vertical air duct 2.

[0031] As a preferred embodiment, multiple forward air outlets 3 and upward air outlets 4 can be provided on the transverse air duct 1 and the longitudinal air duct, and each forward air outlet 3 and upward air outlet 4 can be individually controlled to open or close by a switch valve.

[0032] In another preferred embodiment, the central axes of a forward air outlet 3 and an upward air outlet 4 intersect, and a reversing valve controls the upward or forward airflow, or both the upward air outlet 4 and the forward air outlet 3 to be closed. Of course, the forward air outlet 3 can also be designed as a rearward air outlet, allowing it to blow air forward or backward depending on the site installation convenience, and this should also be within the scope of protection of this patent application.

[0033] This patented cold air outlet duct can be configured to either exhaust air upwards or forwards, depending on the height of the washing and disinfection room and other environmental factors. Workers only need to adjust the valves at the upward and forward exhaust vents after installation. Adjusting the angle of the baffle plate 7 allows for either side-blowing or downward-blowing. Side-blowing cools the workers washing dishes, while downward-blowing dries the clean dishes quickly. This effectively utilizes the recovered heat to cool the room and dry the dishes.

[0034] 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.
