Description

Technical Field

[0001] This utility model relates to the technical field of drying equipment, and in particular to a dishwasher circulating drying device. Background Technology

[0002] Dishwashers are the core equipment for the catering industry to achieve efficient tableware cleaning. As the core module of the dishwasher, the drying mechanism is set in the last stage of the cleaning process. It can accelerate the evaporation of moisture on the tableware through heat energy, ensuring that the tableware reaches a dry state in a short time.

[0003] Currently, existing drying mechanisms typically use fans to draw air and blow it onto heating elements, heating the air before it is blown into the drying chamber. This allows for the removal of moisture through thermal convection, thus drying the tableware. However, during the drying process, the air passes rapidly over the heating elements under the influence of the fan, resulting in insufficient heating time and affecting drying efficiency. Furthermore, the hot air passes quickly over the tableware under the fan's force, making it difficult to fully utilize the air's heat for drying, leading to insufficient heat energy utilization and thus prolonged drying time, which in turn affects drying energy consumption. Utility Model Content

[0004] To address the problems mentioned above, this invention provides a dishwasher circulating drying device that can effectively utilize hot airflow for circulating drying, reducing the working pressure of the heating element, effectively reducing energy consumption, and improving drying efficiency and effect.

[0005] The solution adopted by this utility model to solve its technical problem is: a dishwasher circulating drying device, comprising:

[0006] The drying chamber has an internal cavity, and the top of the drying chamber has an air outlet that runs through the cavity.

[0007] A blower is located at the top of the drying chamber, and the output end of the blower is connected to an air outlet for blowing air into the chamber.

[0008] A heating mechanism, located at the air outlet and connected to the output end of the fan, is used to heat the air output by the fan; and

[0009] A circulation mechanism is provided, wherein the circulation component is located on the drying chamber and communicates with the cavity, and the input end of the fan is connected to the circulation mechanism for circulating and supplying hot air into the cavity.

[0010] Furthermore, the circulation mechanism includes an exhaust hole located on the top or side wall of the drying chamber and extending into the cavity, and an air collection box connected to the outside of the drying chamber and covering the exhaust hole. The air collection box has a connection port, and the input end of the fan is connected to the connection port.

[0011] Furthermore, a flow guide shroud is provided inside the cavity and at the position corresponding to the air collection box. The flow guide shroud is located next to the air extraction hole, and the opening of the flow guide shroud faces the air outlet.

[0012] Furthermore, the heating mechanism includes a heating box covered at the air outlet and a heater installed inside the heating box. The top of the heating box is provided with a communication port, and the output end of the fan is connected to the communication port.

[0013] Furthermore, the cavity is provided with an air guide cover covering the air outlet, and multiple air guide plates are arranged inside the air guide cover. Drying channels for hot air to pass through are formed between two adjacent air guide plates and between the air guide plates located on the side and the air guide cover.

[0014] Furthermore, the cross-section of the air guide plate is an inverted "V" shape.

[0015] Furthermore, the cavity is provided with a transport track for transporting tableware, and below the transport track and at a position corresponding to the air outlet, there is an air concentrator for concentrating hot air.

[0016] Furthermore, the cross-section of the wind-gathering plate is a "V" shaped structure, and a drainage hole is provided at the lowest point in the middle of the wind-gathering plate.

[0017] Furthermore, a drain hole is provided at the bottom of the drying chamber at the position corresponding to the drain hole.

[0018] Furthermore, the drying chamber is provided with transport openings at both ends for tableware to pass through, and the top of the transport openings is connected to an isolation curtain.

[0019] In summary, the beneficial effects of this utility model are as follows: By setting a circulation mechanism connected to the cavity in the drying chamber and connecting the input end of the fan to the circulation mechanism, when the fan draws air, the air that is still hot after drying in the cavity can be drawn through the circulation mechanism and blown to the heating mechanism, thereby reheating the hot air. This fully utilizes the heat of the air, effectively increases the air temperature, and thus improves the drying efficiency and effect. Furthermore, the repeated heating of the hot air by the heating mechanism can effectively reduce the working pressure of the heating mechanism, thereby reducing drying energy consumption.

[0028] To make the content of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

[0029] It should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "inner," and "outer" used herein to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Unless otherwise stated, "a plurality of" means two or more.

[0030] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figures 1 to 4As shown, a dishwasher circulating drying device utilizes hot airflow for circulating heating and drying, reducing the working pressure of the heating element, thereby effectively reducing energy consumption and improving drying efficiency and effect. The drying device in this embodiment includes a drying chamber 1, a fan 2, and a heating mechanism 3 mounted on the drying chamber 1. The drying chamber 1 has a hollow structure with an internal cavity 11 for storing tableware. An air outlet 12 extending through the cavity 11 is located at the top of the drying chamber 1. The heating mechanism 3 is located at the air outlet 12, and the fan 2 is located at the top of the drying chamber 1, with its output end connected to the heating mechanism 3. This allows the fan 2 to draw air into the heating mechanism 3, heat it, and then blow it into the cavity 11, achieving the heating and drying of the tableware inside the cavity 11.

[0032] In order to improve the utilization rate of heat and thus improve the drying efficiency, the drying chamber 1 in this embodiment is also equipped with a circulation mechanism 4. The input end of the circulation mechanism 4 is connected to the cavity 11, and the input end of the fan 2 is connected to the circulation mechanism 4. After the hot air is blown into the cavity 11 by the fan 2 for drying, the fan 2 can continue to draw the air that is still hot after drying through the circulation mechanism 4 and blow it to the heating mechanism 3. Thus, the air is reheated by the heating mechanism 3 and then input into the cavity 11 to dry the tableware. This realizes the circulation supply of hot air, which can increase the temperature of the air and effectively reduce the heating pressure of the heating mechanism 3, making full use of the heat of the air, thereby improving the drying efficiency and drying effect.

[0033] Specifically, such as Figures 3 to 5 As shown, the circulation mechanism 4 in this embodiment includes an exhaust hole 41 on the top or side wall of the drying chamber 1 and an air collection box 42 on the top of the drying chamber 1 and covering the exhaust hole 41. The exhaust hole 41 extends into the cavity 11, and the air collection box 42 is provided with a connection port 421 connected to the input end of the fan 2. After the fan 2, the heating mechanism 3 and the air collection box 42 are connected, a closed-loop air circulation system can be formed. The hot air in the cavity 11 can be drawn into the air collection box 42 through the exhaust hole 41 under the action of the fan 2, and then return to the input end of the fan 2. After mixing with fresh air, it re-enters the heating mechanism 3 for reheating and then enters the cavity 11 for drying. This allows the air with residual heat to be reused, which greatly reduces the working pressure and energy consumption of the heating mechanism 3. At the same time, the temperature can be increased after air circulation, thereby improving the drying efficiency and effect.

[0034] And, as Figures 3 to 5As shown, in this embodiment, a guide hood 43 is also provided inside the cavity 11 and at the position corresponding to the air collection box 42. The guide hood 43 is located next to the exhaust hole 41, and the opening of the guide hood 43 faces the air outlet 12. After the hot air is blown out from the air outlet 12 for drying, it can move towards the exhaust hole 41 under the action of the fan 2. Under the guidance of the guide hood 43, it flows to the exhaust hole 41 and finally enters the air collection box 42 and is blown towards the air outlet for circulating heating. This improves the circulation efficiency of the hot air and avoids the failure of hot air extraction due to airflow turbulence.

[0035] like Figures 4 to 5 As shown, in this embodiment, the output end of the fan 2 is connected to the heating mechanism 3, thereby delivering air to the heating mechanism 3 for heating before it enters the cavity 11 for drying. Specifically, the heating mechanism 3 in this embodiment includes a heating box 31 and a heater 32. The heating box 31 is located on top of the drying chamber 1 and covers the air outlet 12. The top of the heating box 31 has a connecting port 311. The heater 32 is built into the heating box 31. The output end of the fan 2 is connected to the connecting port 311, thereby delivering the extracted air into the heating box 31. At this time, an independent heating space is formed inside the heating box 31, which prolongs the residence time of the air in the heating area after it enters the heating box 31. This allows the heater 32 to fully heat the air, avoiding the problem of insufficient heating caused by the air quickly passing over the heating element, and improving the heating efficiency. The heater 32 can be any one of an electric heating wire, a PTC element, or a heating tube. In this embodiment, the heater is a heating tube, and fins are arranged around the heating tube so that the heat generated when the heating tube heats up can be quickly dissipated by the fins into the heating space formed by the heating box 31, thereby achieving rapid heating of the air.

[0036] And, as Figure 3 As shown, in order to ensure that the heated air can fully cover the tableware and improve the drying effect, this embodiment also provides an air guide hood 5 on the top of the cavity 11. The air guide hood 5 covers the air outlet 12, so that when the air is heated by the heater 32 and blown out from the air outlet 12, it can be diffused to various positions of the cavity 11 under the action of the air guide hood 5, thereby fully covering the tableware and achieving efficient drying.

[0037] Specifically, such as Figure 4 and Figure 6As shown, in this embodiment, multiple air guide plates 51 with an inverted "V" shaped cross-section are arranged inside the air guide hood 5. The adjacent air guide plates 51 are spaced apart, so that a drying channel 52 for hot air passage can be formed between two adjacent air guide plates 51 and between the air guide plates 51 located on the side and the air guide hood 5. When hot air is blown out from the air outlet 12, the top of the air guide plate 51 can divide the hot air into multiple airflows and enter the drying channel 52 along the inclined surface of the air guide plate 51. Thus, the drying channel 52 evenly covers all surfaces of the tableware, achieving all-round drying.

[0038] In practical application, the drying device of this embodiment is typically connected to the end of a dishwasher. After the dishes are cleaned in the washing process at the front end, they can be transported to the drying chamber 1 for drying. Specifically, as shown... Figure 1 and Figure 4 As shown, in order to transport tableware, the cavity 11 of this embodiment is provided with a transport track for transporting tableware. At the same time, the drying chamber 1 is provided with transport openings 14 at both ends for the transport track to pass through, so that the tableware can enter the cavity 11 from one side transport opening 14 under the action of the transport track, and after drying, it can be output from the other side transport opening 14 by the transport track.

[0039] Among them, such as Figures 2 to 4 As shown, in order to further improve the drying efficiency and effect, this embodiment also provides an air concentrator 6 inside the cavity 11 and below the transport track. The air concentrator 6 is set corresponding to the air outlet 12, and the area of ​​the air concentrator 6 is larger than the area of ​​the air guide hood 5. After the hot air is cut by the air guide 51 to form multiple hot air streams to dry the tableware and sink, the sinking hot air can be gathered by the air concentrator 6, thereby drying the bottom and edges of the tableware below the transport track, thus further improving the drying effect of this embodiment.

[0040] And, as Figures 2 to 3 As shown, the cross-section of the air-collecting plate 6 in this embodiment is a "V" shaped structure, and a drain hole 61 is provided at the lowest point in the middle of the air-collecting plate 6, so that water dripping from the surface of the tableware can slide down the inclined surface of the air-collecting plate 6 to the drain hole 61 for discharge. In addition, a drain hole 13 is also provided at the bottom of the drying chamber 1 of this embodiment corresponding to the position of the drain hole 61, so that the water discharged from the drain hole 61 can be discharged out of the chamber 11 through the drain hole 13, avoiding water accumulation and affecting the drying efficiency.

[0041] like Figures 1 to 3As shown, the top of the transport opening 14 in this embodiment is also connected to an isolation curtain 7. The isolation curtain 7 is made of high-temperature resistant silicone or flexible plastic. While ensuring that the tableware passes through smoothly, it minimizes the heat loss in the cavity 11. In addition, it can also effectively prevent the entry of cold air from the outside and maintain the temperature stability inside the cavity 11. At the same time, it can also isolate the water from the previous washing process, thereby ensuring the efficient drying of the tableware.

[0042] In summary, this embodiment, by setting a circulation mechanism 4 connected to the cavity 11 on the drying chamber 1 and connecting the input end of the fan 2 to the circulation mechanism 4, allows the fan 2 to draw air, which still carries heat after drying, through the circulation mechanism 4 and blow it towards the heating mechanism 3, thereby reheating the hot air. This fully utilizes the heat of the air, effectively increasing the air temperature and thus improving drying efficiency and effect. Furthermore, the repeated heating of the air by the heating mechanism 3 effectively reduces the working pressure of the heating mechanism 3, thereby reducing drying energy consumption.

[0043] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
