Description

Technical Field

[0001] This utility model relates to the field of disinfection cabinet equipment technology, and more specifically to a steam generating device for a steam disinfection cabinet. Background Technology

[0002] With the continuous development of society, people are paying more and more attention to food safety. Therefore, the disinfection of tableware is particularly important. At present, the disinfection methods of tableware in the market are not uniform. Generally, households use boiling water to scald the tableware, while others use steam to disinfect the tableware. For steam disinfection, a steam generator is usually installed in the cabinet. The existing steam generators generally use water to boil and then discharge steam to disinfect the tableware in the cabinet. However, in the existing steam generators, the exhaust pipe is in contact with the outside space. This makes it easy for water droplets in the air to adhere to the outer wall of the exhaust pipe after it is heated. Over time, the solution will cause corrosion and damage to the pipe wall. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a steam generating device for a steam sterilizer. It is equipped with an outer protective cover on the outside of all vertical pipes. At the same time, it ensures that the temperature inside the outer protective cover is raised, so that the external space comes into contact with the outer protective cover. The condensation of water droplets from the outside air will not enter the interior of the outer protective cover, making it difficult for water droplets to adhere to the internal vertical pipes and ensuring their service life.

[0004] The solution of this utility model to the aforementioned technical problem is:

[0005] A steam generating device for a steam sterilizer includes a water tank body, wherein multiple heating pipes are installed in the lower part of the interior of the water tank body, and the two ends of the heating pipes are fixed to the lower inner sidewalls of the left and right side plates of the water tank body.

[0006] The top plate of the main body of the water tank is connected to multiple vertical pipes extending upwards. The top end of the vertical pipes is fixed with the same top connecting plate. Multiple steam vent holes are formed on the top connecting plate, and each steam vent hole is connected to the corresponding vertical pipe.

[0007] The top surface of the top plate of the water tank body is fixed with an outer protective cover, and all vertical pipes are inside the outer protective cover. Multiple top air jet holes are formed on the top plate of the outer protective cover.

[0008] A water inlet connector is connected to the middle of one side panel of the main body of the water tank.

[0009] A water receiving trough is installed on the top plate of the main body of the water tank. A connecting groove is formed in the middle of the water receiving trough. The outer protective cover is inserted into the connecting groove, and a sealing ring is clamped between its outer side wall and the inner side wall of the connecting groove.

[0010] The outstanding effect of this utility model is:

[0011] Compared with existing technologies, it sets an outer protective cover on the outside of all vertical pipes. At the same time, it ensures that the temperature inside the outer protective cover is raised, so that the external space comes into contact with the outer protective cover. Condensation droplets from the outside air will not enter the interior of the outer protective cover, making it less likely for water droplets to adhere to the internal vertical pipes and ensuring their service life.

[0012] Meanwhile, its water receiving tank can collect condensate droplets from the outer surface of the outer protective cover and return them to the main body of the water tank for continued use, resulting in good water-saving performance. Attached Figure Description

[0014] Figure 2 This is a partial enlarged view of the present invention;

[0015] Figure 3 This is a partial side view of the present invention. Detailed Implementation

[0016] For example, see below. Figures 1 to 3 As shown, a steam generating device for a steam sterilizer includes a water tank body 10. Multiple heating pipes 11 are installed in the lower part of the interior of the water tank body 10. The two ends of the heating pipes 11 are fixed to the lower inner sidewalls of the left and right side plates of the water tank body 10. The electrical connection wires of the heating pipes 11 extend out of one side plate of the water tank body 10 and out of the outer sidewall of the sterilizer body to which they are fixed.

[0017] The top plate of the water tank body 10 is connected to a plurality of vertically extending vertical pipes 12. The top end of the vertical pipes 12 is fixed to the same top connecting plate 13. The top connecting plate 13 is formed with a plurality of steam vent holes 14, and each steam vent hole 14 is connected to the corresponding vertical pipe 12.

[0018] The top surface of the top plate of the water tank body 10 is fixed with an outer protective cover 20 by stainless steel screws. All vertical pipes 12 are located in the outer protective cover 20. Multiple top air jet holes 21 are formed on the top plate of the outer protective cover 20.

[0019] Furthermore, all vertical tubes 12 are inserted into the connecting through holes of multiple heat sinks 1, and the inner sidewall of the connecting through hole is pressed against the outer sidewall of the corresponding vertical tube 12 and welded and fixed. The heat sink 1 is located in the outer protective cover 20.

[0020] In this embodiment, the heat sink 1 allows the overall temperature inside the outer protective cover 20 to rise rapidly, thereby greatly reducing the water content inside the space. This makes it less likely for water droplets to appear on the inner wall of the outer protective cover 20 and the outer wall of the vertical pipe 12. Generally, there will be water on the surface when it is first turned on, but after a long period of operation, the water droplets will evaporate into water vapor and be discharged from the outer protective cover 20.

[0021] Furthermore, a water inlet connector 15 is connected to the middle of one side panel of the water tank body 10. A water inlet pipe can be connected to the water inlet connector 15, which can then be connected to a water pump. The water inlet of the water pump can be connected to an external water tank or other water source to supply water. This is a conventional structure and will not be described in detail here.

[0022] Furthermore, a water receiving trough 30 is installed on the top plate of the water tank body 10. A connecting groove 31 is formed in the middle of the water receiving trough 30. The outer protective cover 20 is inserted into the connecting groove 31. A sealing ring 2 is clamped between its outer side wall and the inner side wall of the connecting groove 31. The bottom surface of the water receiving trough 30 is pressed against the top plate of the water tank body 10.

[0023] A float level sensor 3 is fixed on the upper part of one side plate of the water receiving tank 30. The float of the float level sensor 3 is located in the water receiving tank 30 and close to the bottom plate of the water receiving tank 30.

[0024] A return liquid through hole 16 is formed on the upper part of one side plate of the water tank body 10, and a liquid outlet through hole 310 is formed on the lower side plate of the water receiving tank body 30. The connecting pipe connected to the inlet of the return liquid transfer pump 5 is fixed on the lower side plate of the water receiving tank body 30 and communicates with the liquid outlet through hole 310. The connecting pipe connected to the outlet of the return liquid transfer pump 5 is fixed on one side plate of the water tank body 10 and communicates with the return liquid through hole 16.

[0025] The water tank body 10 is located inside the main disinfection tank, while the return liquid transfer pump 5 is located outside the main disinfection tank. Connecting pipes at the inlet and outlet of the return liquid transfer pump 5 are inserted into through holes on the corresponding side plates of the main disinfection tank, with the outer ends of the connecting pipes extending beyond the corresponding through holes. This location of the return liquid transfer pump 5 outside the main disinfection tank makes it less prone to damage and ensures its service life.

[0026] In this embodiment, the water in the main body 10 of the water tank is heated rapidly by the heating tube 11 until it boils. At this time, the steam is discharged from the steam outlet 14 along the vertical pipe 12, and then discharged from the top jet outlet 21 formed on the top plate of the outer protective cover 20 to sterilize and heat the outside. During this process, a large amount of condensate is easily adhered to the outer wall of the outer protective cover 20, which will flow into the water receiving tank 30. When the float level sensor 3 senses that the water level has reached the set value, it will send the sensing signal to the control host (the electrical components in this embodiment are electrically connected to the control host through the electrical connection line. The control host is a conventional structure and will not be described in detail here. It is not shown in the attached drawings. It can be installed on the casing of the disinfection cabinet). The control host then controls the return liquid transfer pump 5 to run, so that the water in the water receiving tank 30 flows back into the main body 10 of the water tank and can continue to be used, thus achieving a water-saving effect.

[0027] Moreover, due to the protection of the outer protective cover 20, the internal components are not prone to water accumulation, thus ensuring their service life. However, the outer protective cover 20 is prone to water accumulation. If the outer protective cover 20 is damaged after a certain period of use, you only need to pull the water collection tank 30 upwards and then directly disassemble and replace the outer protective cover 20. The replacement is convenient.

[0028] like Figure 3 As shown, this implementation has an overall vertical and flat shape, which makes its installation space occupancy small.

[0029] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
