Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a commercial dishwasher air knife device for removing water stains. Background Technology

[0002] The air knife in a commercial dishwasher is a device that uses high-speed compressed air to form a uniform air curtain. Installed at the outlet of the drying zone, it quickly and efficiently blows away any residual water droplets as washed dishes pass through, preventing water stains and shortening drying time, thus improving overall machine efficiency. Because of its uniform airflow distribution, the air knife not only ensures effective drying of the dishes but also reduces heating energy consumption.

[0003] However, in actual use, the aforementioned air knife can only effectively reach certain areas due to the large differences in the shape of the tableware. Concave or upright tableware is prone to forming dead corners, making it difficult to dry residual water. If water droplets in certain areas cannot be blown away in time, water stains or water spots will remain, affecting the cleanliness of the tableware and the user experience. In view of this, we propose a commercial dishwasher air knife water stain removal device. Utility Model Content

[0004] The purpose of this invention is to provide a commercial dishwasher air knife device for removing water stains, so as to solve the problems mentioned in the background art.

[0015] Preferably, a cover is fixedly connected to the outer wall of the housing, the inner bottom surface of the cover is movably connected to the bottom end face of the air outlet cover, and a wave groove is provided on the bottom end face of the cover.

[0016] Compared with the prior art, this utility model provides a commercial dishwasher air knife water stain removal device, which has the following beneficial effects:

[0017] 1. This commercial dishwasher's air knife water stain removal device, through its adjustable components, allows the air outlet to swing, greatly increasing the airflow coverage of the air knife. This enables it to reach more angles, significantly reducing dead zones for residual water. The constantly changing airflow direction means that every surface of the tableware is swept by air, making it easier to remove water droplets, accelerating drying speed, and shortening drying time. This improves overall machine efficiency and reduces energy consumption. The reduced residual water, water stains, and water spots are also addressed. A rubber sleeve connects the outer wall of the air outlet to the outer wall of the housing. While the air outlet can move, air only blows out from the air outlet, maximizing airflow utilization efficiency. The airflow is precisely guided to the tableware surface, rather than escaping through gaps. This allows the air knife design to fully perform its function, ensuring that all angles of the tableware are evenly dried, reducing residual water or water stains.

[0018] 2. The air knife water stain removal device of this commercial dishwasher uses a set of wave grooves to allow the airflow to be deflected and diffused laterally along the groove curve, covering more tableware surfaces, avoiding the situation where the airflow is concentrated in a small area and the drying is too strong in some areas and insufficient in other areas, further reducing dead corners and improving drying uniformity.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a commercial dishwasher air knife water stain removal device, including a housing 1, and an adjustment component 2 is provided inside the housing 1. The adjustment component 2 includes a cylinder 201, a rotating rod 202, a blade 203, a turntable 204, a connecting rod 205, a hinge frame 206, an air outlet cover 207, an air outlet 208, and a rubber sleeve 209.

[0026] In one embodiment of this utility model, a cylindrical body 201 is fixedly connected to the side wall of the housing 1. A rotating rod 202 is provided inside the cylindrical body 201. A blade 203 is fixedly connected to the side wall of the rotating rod 202. A fixing frame 4 is fixedly connected to the inner wall of the cylindrical body 201. The fixing frame 4 is rotatably connected to the rotating rod 202. The blade 203 does not contact the inner wall of the cylindrical body 201. The blade 203 is spirally coiled around the outer wall of the rotating rod 202. An air inlet pipe 3 is fixedly connected to the side wall of the cylindrical body 201. Air is blown into the cylindrical body 201 through the air inlet pipe 3.

[0027] The turntable 204 is fixedly connected to the end face of the rotating rod 202. A connecting rod 205 is fixedly connected to the side wall of the turntable 204. The connecting rod 205 is fixedly connected to the turntables 204 on both sides, thereby causing the rotating rod 202 and the hinge frame 206 to move synchronously. The axis of the connecting rod 205 is parallel to that of the rotating rod 202. The rotation of the rotating rod 202 drives the turntable 204 and the connecting rod 205 to rotate.

[0028] The hinge frame 206 is rotatably connected to the inner top surface of the housing 1. The side wall of the hinge frame 206 is provided with a slot 210, which is slidably connected to the connecting rod 205. The bottom of the hinge frame 206 is connected to an air outlet 207, and the bottom of the air outlet 207 is provided with an air outlet 208. The number of air outlets 208 is set in several groups, and the several groups of air outlets 208 are equally spaced at the bottom of the air outlet 207.

[0029] The rubber sleeve 209 is fixedly connected to the outer wall of the housing 1, and the rubber sleeve 209 is fixedly connected to the outer wall of the air outlet hood 207.

[0030] Air is blown into the cylinder 201 through the air inlet pipe 3. The air blows the blades 203 and the rotating rod 202 to rotate, causing the turntable 204 and the connecting rod 205 to rotate. The connecting rod 205 drives the hinge frame 206 to swing back and forth. The connecting rod 205 slides back and forth in the slot 210, which in turn causes the air outlet hood 207 and the air outlet 208 to swing. The air passes through the blades 203 to rotate the rotating rod 202, converting aerodynamic energy into mechanical energy. No additional motor is required, and the structure is simple. By swinging through the air outlet 208, the airflow coverage of the air knife is greatly increased, and it can blow to more angles, significantly reducing dead spots of residual water. The constantly changing air direction means that the surface of each piece of tableware can be swept by air, and water droplets are more easily carried away, thus speeding up the drying speed and shortening the drying time. This can improve the overall working efficiency of the machine, reduce energy consumption, reduce residual water, and reduce water stains and water spots.

[0031] The rubber sleeve 209 connects the outer wall of the air outlet 207 to the outer wall of the housing 1. While the air outlet 207 can move, air is only blown out from the air outlet 208, maximizing the efficiency of airflow utilization. The airflow is precisely guided to the surface of the tableware instead of being lost through gaps. This allows the design effect of the air knife to be fully utilized, and the tableware can be dried evenly from all angles, reducing residual water or water stains.

[0032] In addition, a cover 5 is fixedly connected to the outer wall of the shell 1. The inner bottom surface of the cover 5 is movably connected to the bottom end face of the air outlet 207. A wave groove 6 is provided on the bottom end face of the cover 5. The wave groove 6 guides the air blown out from the air outlet 208. The design of the wave groove 6 allows the airflow to shift and diffuse laterally along the groove curve, covering more tableware surfaces and avoiding the situation where the airflow is concentrated in a small area, resulting in localized excessive drying and insufficient drying in other areas. This further reduces dead corners and improves drying uniformity.

[0033] In this invention, during use, air is blown into the cylinder 201 through the air inlet pipe 3. The air blows the blades 203 and the rotating rod 202 to rotate, causing the turntable 204 and the connecting rod 205 to rotate. The connecting rod 205 drives the hinge frame 206 to swing back and forth. The connecting rod 205 slides back and forth in the slot 210, thereby causing the air outlet hood 207 and the air outlet 208 to swing. The air passes through the blades 203 and rotates the rotating rod 202, converting aerodynamic energy into mechanical energy. No additional motor is required, and the structure is simple. By swinging through the air outlet 208, the airflow coverage of the air knife is greatly increased, and it can blow to more angles, significantly reducing dead corners of residual water. The constantly changing air direction means that the surface of each tableware can be swept by air, and water droplets are more easily carried away, improving the overall working efficiency of the machine.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
