Description

Technical Field

[0001] This utility model relates to food processing equipment, specifically to a steam steamer. Background Technology

[0002] Steam cabinets produce condensate during operation, which needs to be drained promptly to avoid wasting heat. However, traditional condensate drain pipes release steam along with the drained water, resulting in wasted heat. Utility Model Content

[0003] The technical problem solved by this utility model is that condensate drain pipes release steam at the same time as draining water, wasting heat.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a condensate drain device for a steam cabinet, including a condensate drain pipe, the condensate drain pipe having a drooping section, a narrow passage in the drooping section, a float ball above the narrow passage, the float ball being located in the drooping section, and the narrow passage being able to be blocked by the float ball.

[0005] When there is no condensate, the float blocks the opening, preventing the condensate drain pipe from flowing and thus preventing steam leakage. When condensate is produced, it collects above the lower section of the opening. As the condensate depth increases, buoyancy increases until the float rises. With the float up, the opening opens, and the condensate drains out. When there is no condensate above the opening, the float, no longer subject to buoyancy, presses against the opening under gravity, sealing it and preventing steam leakage.

[0006] When condensate is drained, the steam in the drain pipe is blocked by the condensate and cannot escape through the obstruction; after the condensate is drained, the float descends and blocks the obstruction, preventing steam from escaping. This avoids heat waste.

[0007] The inner diameter of the obstruction is smaller than the diameter of the buoy, so that the buoy can block the obstruction. The diameter of the buoy is smaller than the inner diameter of the drooping section, so that the buoy can rise and fall freely in the drooping section. As an alternative, the buoy is a hollow sphere.

[0008] As an alternative, the centerline of the pass coincides with the centerline of the descending section.

[0009] The condensate drain pipe includes a first elbow and a second elbow. A partition is provided at the connection between the first elbow and the second elbow, and an opening is made on the partition. The first elbow and the second elbow are spliced ​​together to form the drooping section.

[0010] Alternatively, the partition is bonded between the first elbow pipe and the second elbow pipe. The outer diameter of the partition is equal to the outer diameter of both the first and second elbow pipes. Thus, during bonding, the outer edge of the partition is aligned with the outer walls of the first and second elbow pipes, indicating that the slit at the center of the partition is positioned at the center of the drooping section.

[0011] As an improvement, a step is provided on the inner wall of the drooping section, and a guide plate is fitted inside the drooping section. A guide hole is opened in the center of the guide plate, and the float is located below the guide plate. Condensate flows through the guide hole of the guide plate and then flows downward to the top of the narrow passage. When the water depth reaches a certain depth, the float rises, opening the narrow passage and allowing the condensate to drain out. When there is no condensate, steam acts on the float through the guide hole. Because the guide hole, the narrow passage, and the float sealing the narrow passage are all centered, the steam will not drive the float to the side of the narrow passage and open it. In this way, the narrow passage will not open when there is no condensate.

[0012] The condensate draining device of this invention is applied to a steam cabinet. While draining water, it can prevent steam from being discharged at the same time, thus avoiding heat waste. Attached Figure Description

[0025] Combine Figures 1 to 3 The condensate drain device of the steam cabinet includes a condensate drain pipe with a drooping section 10 and a slit 21 in the drooping section. A float 30 is provided above the slit and is located in the drooping section. The slit can be blocked by the float.

[0026] When there is no condensate, float 30 blocks the obstruction 21, preventing the condensate drain pipe from flowing and thus preventing steam leakage. When condensate is generated, it accumulates above the obstruction 21. As the condensate depth increases, buoyancy increases until float 30 floats. With the float up, obstruction 21 opens, allowing the condensate to drain out. With no condensate above the obstruction, float 30 is not subject to buoyancy and, under the influence of gravity, presses against obstruction 21, sealing it and preventing steam leakage.

[0027] When draining condensate, the steam in the condensate drain pipe is blocked by the condensate and cannot be discharged through the obstruction 21; after the condensate is drained, the float 30 descends to block the obstruction 21, and steam can no longer be discharged. In this way, heat waste is avoided.

[0028] The inner diameter of the obstruction 21 is smaller than the diameter of the float 30, so that the float can block the obstruction 21. The diameter of the float is smaller than the inner diameter of the drooping section 10, so that the float 30 can rise and fall freely in the drooping section 10. Alternatively, the float 30 can be a hollow sphere.

[0029] The centerline of the pass 21 coincides with the centerline of the drooping section 10.

[0030] The condensate drain pipe includes a first elbow pipe 40 and a second elbow pipe 50. A partition 20 is provided at the connection between the first elbow pipe and the second elbow pipe, and a notch 21 is opened on the partition. The first elbow pipe 40 and the second elbow pipe 50 are spliced ​​together to form the drooping section 10.

[0031] The partition 20 is bonded between the first elbow pipe 40 and the second elbow pipe 50. The outer diameter of the partition 20 is equal to the outer diameter of the first elbow pipe 40 and the outer diameter of the second elbow pipe 50. Thus, during bonding, the outer edge of the partition 20 is aligned with the outer side wall of the first elbow pipe and the second elbow pipe, indicating that the notch 21 at the center of the partition 20 is located at the center of the drooping section 10.

[0032] like Figure 4 As an improvement, a step 11 is provided on the inner wall of the drooping section 10, and a guide plate 60 is fitted inside the drooping section. A guide hole 61 is opened in the center of the guide plate, and the float 30 is located below the guide plate. Condensate flows through the guide hole 61 of the guide plate 60 and then flows downward to the top of the narrow passage 21. When the water depth reaches a certain depth, the float 30 floats up, opening the narrow passage 21, and the condensate is discharged. When there is no condensate, steam acts on the float 30 through the guide hole 61. Since the guide hole 61 is centered, the narrow passage 21 is centered, and the float 30 blocking the narrow passage is centered, the steam will not drive the float 30 to move to the side of the narrow passage 21 and open the narrow passage. In this way, it is ensured that the narrow passage 21 will not open when there is no condensate.

[0033] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
