Description

Technical Field

[0001] The utility model relates to the field of evaporators, in particular to an instant heating type pressurized evaporator structure. Background Art

[0002] As people's living standards continue to improve, small household cleaning equipment with water tanks, such as steam mops and floor scrubbers, have gradually become popular. In order to improve the cleaning effect, these devices usually use evaporators to heat water to generate steam. However, in the prior art, due to the volume of the cleaning equipment, the volume of the evaporator (evaporation area) is designed to be relatively small, resulting in low evaporation efficiency. After the water enters the evaporator, due to incomplete evaporation, the water content of the ejected steam is relatively large, or water droplets are directly ejected, which affects the cleaning effect and the user experience is poor. In addition, U-shaped heating tubes are generally used for heating in the prior art. Since the heating path of the U-shaped heating tube is not long enough, it is impossible to achieve high power and high efficiency, resulting in a long heating time of the evaporator and low hot sales. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an instant heating type pressurized evaporator structure, which increases the heating area, improves the heating efficiency, and makes the heating path of the heating tube longer and the heat release more uniform.

[0004] The purpose of the utility model is achieved through the following technical solutions: This instant hot pressurized evaporator structure includes:

[0005] A shell, wherein a partition plate with an approximately rectangular outline is provided in the shell, the inner cavity of the shell is divided into a central heating area and an edge heating area surrounded by the central heating area, and the central heating area and the edge heating area are connected through a notch provided on the partition plate;

[0006] A water baffle is arranged on the shell in the central heating area and is used to cooperate with the partition plate to further separate the central heating area;

[0007] An upper cover plate is mounted on the shell and is provided with a water inlet connected to the central heating area;

[0008] The electric heating pipe is integrally formed with the shell and adopts an M-shaped structure so that the heating path of the electric heating pipe covers both the central heating area and the edge heating area; and

[0009] The steam outlet cavity is arranged on the side of the shell inner cavity away from the notch, and the steam outlet cavity is connected with the edge heating area. A plurality of steam outlets connected with the steam outlet cavity are arranged on the outer wall of the shell, and the steam outlets include a central steam outlet and edge steam outlets located on both sides of the central steam outlet.

[0010] As a further technical solution, two central steam outlet baffles are arranged in the steam outlet cavity, and the central steam outlet baffles are arranged on both sides of the central steam outlet.

[0011] As a further technical solution, a plurality of edge steam outlet baffles are further arranged in the steam outlet cavity, and the edge steam outlet baffles are located outside the central steam outlet baffle.

[0012] As a further technical solution, the gap between the central steam outlet baffle and the upper cover plate is smaller than the gap between the edge steam outlet baffle and the upper cover plate.

[0013] As a further technical solution, the central steam outlet baffle and the edge steam outlet baffle are connected between the shell and the partition plate.

[0014] As a further technical solution, the water retaining plate adopts a labyrinth structure, and the water inlet is connected to the center of the labyrinth structure.

[0015] As a further technical solution, a plurality of riveting holes are provided on the tops of the partition plate and the water retaining plate, so that the shell and the upper cover plate are riveted together by riveting nails.

[0016] As a further technical solution, a plurality of heat-conducting protrusions are evenly distributed on the inner wall of the shell corresponding to the central heating area and the edge heating area.

[0017] As a further technical solution, the heat-conducting protrusion adopts a conical structure.

[0018] The beneficial effects of the utility model are:

[0019] 1. A labyrinth-type water baffle is set inside the shell to extend the flow path of water in the central heating area to ensure that the water is fully heated;

[0020] 2. The electric heating tube adopts an M-shaped structure, which has a longer heating path and more uniform heat release than the U-shaped tube, ensuring that the heating path of the electric heating tube covers both the central heating area and the edge heating area. The heating power of the original U-shaped tube is 1000W~1300W, and the heating power reaches 1700W~2000W after changing to the M-shaped heating tube, which greatly improves the heating efficiency and shortens the heating time;

[0021] 3. A steam outlet baffle is set in the steam outlet cavity to ensure the stability of the ejected steam and to separate the residual water to reduce the water content of the ejected steam;

[0022] 4. Conical heat-conducting protrusions are set on the central heating area and the edge heating area, which can expand the contact area with water and steam, fully heat and improve the heat conduction effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The utility model will be described in detail below with reference to the accompanying drawings:

[0031] Example: As attached Figures 1 to 6 As shown, the instantaneous pressurized evaporator structure includes a shell 1, an upper cover plate 2, a water inlet 3, an electric heating tube 4, a rivet pin 5, a central heating area 7, an edge heating area 8, a partition plate 9, a water baffle 10, a notch 11, a steam outlet cavity 12, a heat-conducting protrusion 13, a central steam outlet 14, an edge steam outlet 15, a central steam outlet baffle 16 and an edge steam outlet baffle 17.

[0032] Reference Figure 2 , 3 A partition plate 9 with an approximately rectangular (preferably rounded) outline is provided in the housing 1. The partition plate 9 divides the inner cavity of the housing 1 into a central heating area 7 and an edge heating area 8 surrounding the central heating area 7. A notch 11 is provided at the lower portion of the partition plate 9, and the central heating area 7 and the edge heating area 8 are connected through the notch 11.

[0033] Furthermore, a plurality of water baffles 10 are arranged in the shell 1 corresponding to the central heating area 7. The water baffles 10 adopt a labyrinth structure, which can cooperate with the partition plate 9 to further separate the central heating area 7. At the same time, the water inlet 3 is connected to the center of the labyrinth structure, so that the water flow needs to flow from the innermost side of the labyrinth structure to the outside (extending the flow path of the water flow in the central heating area 7 to ensure that the water flow is fully heated). The flow path of the water flow / steam is as follows: Figure 3 As shown by the dashed arrow. Figure 1 , 2 As shown, the upper cover plate 2 is mounted on the shell 1, and a water inlet 3 connected to the central heating area 7 is provided in the middle of the upper cover plate 2. Preferably, a plurality of riveting holes are provided on the top of the partition plate 9 and the water baffle plate 10, so that the shell 1 and the upper cover plate 2 can be riveted by riveting nails 5. A plurality of conical heat-conducting protrusions 13 are evenly distributed on the inner wall of the shell 1 corresponding to the central heating area 7 and the edge heating area 8, which can expand the contact area with water and steam, fully heat, and improve the heat conduction effect.

[0034] like Figure 5 , 6 As shown, the electric heating tube 4 is integrally formed with the housing 1 and adopts an M-shaped structure, so that the heating path of the electric heating tube 4 covers both the central heating area 7 and the edge heating area 8. Compared with the U-shaped tube, it can achieve the advantages of a longer heating path and more uniform heat release within the same size range. In addition, the heating power of the existing U-shaped tube is 1000W~1300W, and after changing to the M-shaped electric heating tube 4, the heating power reaches 1700W~2000W, which greatly improves the heating efficiency and shortens the heating time.

[0035] Reference Figure 3 , 4 The steam outlet cavity 12 is arranged on the side of the inner cavity of the shell 1 away from the notch 11, and the two ends of the steam outlet cavity 12 are correspondingly connected to the edge heating area 8. A plurality of steam outlets connected to the steam outlet cavity 12 are provided on the outer wall of the shell 1, and the steam outlets include a central steam outlet 14 and edge steam outlets 15 located on both sides of the central steam outlet 14 (four on each side, a total of eight). Two central steam outlet baffles 16 are arranged in the steam outlet cavity 12, and the central steam outlet baffles 16 are arranged on the left and right sides of the central steam outlet 14. Furthermore, two edge steam outlet baffles 17 are also arranged in the steam outlet cavity 12, and the edge steam outlet baffles 17 are located on the outside of the central steam outlet baffle 16, and are symmetrically distributed on the left and right sides. Preferably, the gap between the central steam outlet baffle 16 and the upper cover plate 2 is smaller than the gap between the edge steam outlet baffle 17 and the upper cover plate 2 (i.e., the height of the central steam outlet baffle 16 is greater than the height of the edge steam outlet baffle 17), which can effectively ensure the stability of the ejected steam and at the same time separate the residual water and reduce the water content of the ejected steam. Both the central steam outlet baffle 16 and the edge steam outlet baffle 17 are connected between the housing 1 and the partition plate 9.

[0036] The working process of this utility model:

[0037] like Figure 3 As shown, when the evaporator is working, evaporation water is injected into the inner cavity of the shell 1 (central heating area 7) through the water inlet 3, and steam is generated under the action of the electric heating tube 4 and the heat-conducting protrusion 13. The flow path of the steam is as shown in FIG. Figure 3 As shown by the dashed arrow in the middle, the steam (water) is first fully heated by passing through the maze area surrounded by the water baffle 10, and then flows out from the notch 11 on the partition plate 9 into the edge heating area 8. The steam at the notch 11 is first divided into two paths, flowing along the edge heating areas 8 on the left and right sides of the central heating area 7 and continuing to be heated, and finally converges to the steam outlet cavity 12 and is discharged from the edge steam outlet 15, or is discharged from the central steam outlet 14 after continuously passing through the edge steam outlet baffle 17 and the central steam outlet baffle 16.

[0038] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
