Description

Technical Field

[0001] This disclosure relates to the field of commercial dishwasher technology, and in particular to a drying mechanism for a commercial dishwasher. Background Technology

[0002] Today, dishwashers are becoming increasingly intelligent. Using a dishwasher saves personal time, as it has strong cleaning power and can thoroughly eliminate bacteria on the surface of dishes. Dishwashers are simple to operate yet feature-rich, meeting multiple needs such as washing, drying, and sterilization, providing great convenience to people's daily lives. Depending on the place of use, dishwashers are divided into household dishwashers and commercial dishwashers. Household dishwashers are only suitable for homes and mainly include cabinet-style, countertop, sink-integrated, and combined models. Commercial dishwashers refer to dishwasher equipment used for commercial purposes and can be divided into four main categories according to their structure: cabinet-style, hood-style, basket-type, and belt-type. They are generally used in hotels, restaurants, and other similar establishments.

[0003] Most existing commercial dishwashers use condensation drying to dry dishes. They can also use hot air drying or ventilation drying. Hot air drying works by drawing in hot air from outside through an air inlet, using the temperature difference to cause moisture to adhere to the cool walls on both sides, thus achieving a drying effect. Ventilation drying works by drawing in hot air from outside through an automatic air inlet, heating it through a hot air outlet, causing moisture to adhere to the inner cavity, and simultaneously expelling air through an exhaust vent, thus achieving a drying effect. Both hot air drying and ventilation drying require additional hot air equipment and may even require ventilation ducts in the installation environment, increasing the cost of equipment manufacturing, installation, and operation. Relatively speaking, condensation drying is the most energy-efficient and is the most commonly used drying method in commercial dishwashers.

[0004] Condensation drying is relatively slow. To speed up the drying process, it is often necessary to add electric heating elements inside the dishwasher for localized drying. The electric heating elements in the existing technology are generally U-shaped, and each U-shaped structure requires wiring at one end. For dishwashers with many electric heating elements, the wiring at the terminals not only looks messy, but is also prone to short circuits between the wires. Utility Model Content

[0005] In view of the shortcomings or problems existing in the prior art, this disclosure provides a drying mechanism for a commercial dishwasher, which is stable in operation and safer to use.

[0006] The technical solution adopted by this disclosure to solve the above-mentioned technical problem is as follows: a drying mechanism for a commercial dishwasher, including a heating component, the heating component including a first heating component and a second heating component arranged horizontally in parallel, the first heating component including at least two first heating tubes arranged longitudinally and spaced apart from each other, the second heating component including at least two second heating tubes arranged longitudinally and spaced apart from each other, the first heating tube including two first terminals, the second heating tube including two second terminals, at least two first terminals located away from the second heating component being connected by a first connecting plate, at least two first terminals located close to the second heating component being connected by a second connecting plate, at least two second terminals located close to the first heating component being respectively connected to the second connecting plate, and at least two second terminals located away from the first heating component being connected by a third connecting plate.

[0007] In a preferred embodiment, both the first heating tube and the second heating tube are U-shaped tubes.

[0008] In a preferred embodiment, the first connecting plate is straight, the second connecting plate is U-shaped, and the third connecting plate is either straight or U-shaped.

[0009] In a preferred embodiment, both the first heating tube and the second heating tube are fitted with a plurality of heat-conducting plates.

[0010] In a preferred embodiment, the heating assembly further includes a third heating assembly disposed on the side of the second heating assembly.

[0011] In a preferred embodiment, the third heating component includes at least two longitudinally arranged and spaced apart third heating tubes. Each third heating tube includes two third terminals. At least two third terminals located near the second heating component are respectively connected to a third connecting plate, and at least two third terminals located away from the second heating component are connected through a fourth connecting plate.

[0012] In a preferred embodiment, the first connecting plate and the fourth connecting plate are connected by a connecting rod.

[0013] In a preferred embodiment, the third connecting plate is U-shaped, and a plurality of heat-conducting plates are fitted on the third heating tube.

[0014] In a preferred embodiment, a drying tank is also included, and the heating component is disposed in the drying tank.

[0015] In a preferred embodiment, the drying tank includes a mounting plate with multiple mounting holes, each mounting hole having a flange installed thereon, and each heating tube being connected to the mounting plate via a flange.

[0016] In a preferred embodiment, a guide plate is provided in the drying tank, the guide plate is located below the heating component, and the guide plate is detachably connected to the drying tank.

[0017] In a preferred embodiment, the air guide plate includes an integrally formed first plate and a second plate, and an air duct is provided between the second plate and the drying tank.

[0018] Compared with existing products, since one of the first terminals of the first heating element is connected through a first connecting plate, and the other first terminal of the first heating element is connected to one of the second terminals of the second heating element through a second connecting plate, and the other second terminal of the second heating element is connected through a third connecting plate, the first and second heating components can be powered simply by connecting wires to the first, second, and third connecting plates. This avoids the messy wiring caused by connecting each terminal separately and the short circuit caused by messy wiring. With the above solution, the first heating component can be equipped with multiple first heating elements, and the second heating component can be equipped with multiple second heating elements, while still keeping the wiring neat and orderly, without worrying about messy and tangled wiring.

[0029] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0030] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, the above terms should not be construed as a limitation of this utility model.

[0031] like Figures 1-3As shown, this disclosure provides a drying mechanism for a commercial dishwasher, including a heating assembly. The heating assembly includes a first heating assembly 1 and a second heating assembly 2 arranged horizontally in parallel. The first heating assembly 1 includes at least two first heating tubes 11 arranged longitudinally and spaced apart from each other. The second heating assembly 2 includes at least two second heating tubes 21 arranged longitudinally and spaced apart from each other. Both the first heating tubes 11 and the second heating tubes 21 are U-shaped tubes. The first heating tube 11 includes two first terminals disposed on its end face. The second heating tube 21 includes two second terminals disposed on its end face. At least two first terminals disposed away from the second heating assembly 2 are connected by a first connecting plate 7. At least two first terminals disposed close to the second heating assembly 2 are connected by a second connecting plate 8. At least two second terminals disposed close to the first heating assembly 1 are respectively connected to the second connecting plate 8. At least two second terminals disposed away from the first heating assembly 1 are connected by a third connecting plate 9. The first connecting plate 7 and the third connecting plate 9 are connected by a connecting rod 30. Since one of the first terminals of the first heating tube 11 is connected through the first connecting plate 7, and the other first terminal of the first heating tube 11 is connected to one of the second terminals of the second heating tube 21 through the second connecting plate 8, and the other second terminal of the second heating tube 21 is connected through the third connecting plate 9, the first heating component 1 and the second heating component 2 can be powered simply by connecting wires to the first connecting plate 7, the second connecting plate 8, and the third connecting plate 9. This avoids the messy wiring caused by connecting each terminal separately and the short circuit caused by messy wiring. With the above solution, the first heating component 1 can be equipped with multiple first heating tubes 11, and the second heating component 2 can be equipped with multiple second heating tubes 21, while still keeping the wiring neat and orderly. There is no need to worry about messy and tangled wiring, making it safer to use. The setting of the connecting rod 30 further saves wiring. Connecting a single wire to the connecting rod 30 can simultaneously connect the first connecting plate 7 and the third connecting plate 9.

[0032] Furthermore, the first connecting plate 7, the second connecting plate 8, the connecting rod 30, and the third connecting plate 9 are all made of conductive material. The first connecting plate 7 is straight, the second connecting plate 8 is U-shaped, and in this embodiment, the third connecting plate 9 is straight.

[0033] Please continue reading. Figure 3As shown, to increase the contact area between air and the heating components and improve the drying effect, several heat-conducting plates 6 are fitted onto both the first heating tube 11 and the second heating tube 21. Specifically, the heat-conducting plates 6 are annular metal pieces welded onto the first heating tube 11 and the second heating tube 21, with an installation angle of approximately 90 degrees between the heat-conducting plates 6 and the heating tubes. After air enters the heating components, it comes into contact with the heated first heating tube 11, the second heating tube 21, and the heat-conducting plates 6. The heat-conducting plates 6 impede airflow to a certain extent, thus prolonging the contact time between the air and the heating components.

[0034] Please refer to Figure 3 and Figure 4 As shown, in one embodiment of this disclosure, the heating assembly further includes a third heating assembly 3, which is disposed on the side of the second heating assembly 2 and parallel to it. Specifically, the third heating assembly 3 includes at least two longitudinally arranged and spaced apart third heating tubes 31. Each third heating tube 31 includes two third terminals. The at least two third terminals located closer to the second heating assembly 2 are respectively connected to a third connecting plate 9, and the at least two third terminals located further away from the second heating assembly 2 are connected via a fourth connecting plate 10. The first connecting plate 7 and the fourth connecting plate 10 are connected via a connecting rod 30. The third connecting plate 9 is U-shaped, and a plurality of heat-conducting plates 6 are sleeved on the third heating tubes 31.

[0035] like Figure 3 and Figure 5 As shown, in one embodiment of this disclosure, a drying tank 40 is also included, and the heating assembly is disposed in the drying tank 40. Specifically, the drying tank 40 includes a mounting plate 4, which has a plurality of mounting holes. A flange 5 is installed at each mounting hole, and each heating tube is connected to the mounting plate 4 through the flange 5 and thus fixed.

[0036] Please refer to Figure 6 and Figure 7As shown, to improve the drying effect, a guide plate 20 is provided in the drying tank 40. Specifically, the guide plate 20 is located below the heating element. The guide plate 20 includes a "V"-shaped first plate 201, with a second plate 202 connected to each side of the first plate 201. The second plate 202 has snap-fit ​​protrusions at both ends along its length, and corresponding slots are provided in the drying tank 40. The snap-fit ​​protrusions and slots engage to snap the guide plate 20 into the drying tank 40. A gap is provided between the second plate 202 and the guide plate 20, which forms an air duct 203. A fan is located above the heating element, blowing air downwards towards the heating element. Hot air flows out through the air duct 203 to dry the tableware. The first plate 201, positioned directly below the drying tank 40, can block some of the airflow, allowing the air to remain at the heating element for a longer time, thus heating the air more effectively and increasing its heat content, thereby improving drying efficiency. Furthermore, the "V"-shaped design of the first plate 201 also serves a guiding function. When the fan blows downwards, the heated air inside the drying chamber 40 flows out along the first plate 201 through the air duct 203 to dry the tableware. In this way, two relatively narrow air ducts 203 are formed on both sides of the drying chamber 40. Combined with the downward blowing of the fan from above, the hot air in the drying chamber 40 flows out of the air ducts 203 at a faster speed. The increased air velocity further accelerates the drying speed of the tableware.

[0037] It should be noted that the heating element in this application can employ existing electric heating element technology, such as internally threading resistance wire and filling with magnesium oxide powder for insulation. The heating assembly may also include a fourth heating element or even more, without specific limitations here.

[0038] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
