Description

Technical Field

[0001] This utility model relates to the field of electrical technology for chocolate processing, and more specifically, to a drainage structure and a chocolate mixer. Background Technology

[0002] In chocolate mixers, the heating boiler is a key component, and the rationality of its drainage system directly affects production efficiency and operational safety. Currently, most mainstream chocolate mixer heating boilers on the market use a drain valve design with a nut. In actual drainage operations, this type of design requires manually tightening the nut to open the drainage channel, allowing wastewater from inside the boiler to drain naturally from the drain valve port.

[0003] This direct discharge method has significant drawbacks: Firstly, due to the lack of a dedicated wastewater guiding device, the discharged wastewater is discharged irregularly, making it difficult to accurately connect to the collection container. This leads to wastewater overflow and pollution of the production environment, increasing the workload of subsequent cleaning and treatment. Secondly, the wastewater discharged from the boiler is typically 80-100℃. Without any protection, the direct discharge of high-temperature wastewater poses a significant risk of burns to operators, highlighting a serious safety hazard. In other words, the existing structure amplifies the possibility of accidental contact with high-temperature wastewater during nut tightening operations, which is significantly different from the stringent safety requirements in the food processing industry. Utility Model Content

[0004] This application primarily addresses the risk of burns caused by the disorderly discharge of high-temperature wastewater. To overcome the shortcomings of the prior art, this application provides a drainage structure.

[0005] This application provides a drainage structure, including a heating boiler, a water injection tank, and a drainage pipe, wherein the water injection tank and the drainage pipe are both connected to the interior of the heating boiler, and further includes:

[0006] A switching valve includes a valve body and a valve core assembly. The valve body has a water inlet and a water outlet that are perpendicular to each other. The valve core assembly controls the opening and closing between the water inlet and the water outlet. The water inlet is rotatably fitted onto the outlet end of a drain pipe.

[0007] The drain pipe has its inlet end inserted into the outlet hole and connected to the valve housing. The drain pipe can rotate around the axis of the drain pipe through the valve housing. The drain pipe is transparent and its length is greater than the water injection depth in the heating boiler.

[0008] A retaining component, which is installed between the water inlet tank and the drain pipe, is used to position the outlet end of the drain pipe upwards;

[0009] In the draining state, the drain pipe retracts from the retaining assembly and rotates around the axis of the drain pipe, opening the switch valve. Wastewater in the heating boiler passes through the drain pipe and the switch valve in sequence and is guided out by the drain pipe. In the non-draining state, the drain pipe is set with its outlet facing upward by the retaining assembly. The amount of water injected into the heating boiler is determined by observing the water level in the transparent drain pipe.

[0010] Compared with existing technologies, the drainage structure proposed in this application has the following advantages: In drainage mode, wastewater is guided through a drainage conduit, replacing the existing irregular discharge method, preventing wastewater overflow and environmental pollution, reducing cleaning workload, and avoiding direct discharge of high-temperature wastewater, thus reducing the risk of burns to operators and improving operational safety. In non-drainage mode, by maintaining the components, the water outlet of the transparent drainage conduit faces upwards, allowing direct observation of the water level inside the conduit to determine the water injection volume in the heating boiler, eliminating the need for additional observation devices, simplifying the structure and making operation convenient. Furthermore, the drainage conduit can rotate around the axis of the drainage connector, enabling rapid switching between drainage and non-drainage modes in conjunction with a switch valve, combining drainage and water level observation functions, and improving ease of use.

[0011] In one possible implementation, the retaining assembly includes a connecting pipe and a connecting pipe. The connecting pipe has an inlet and an outlet that communicate with each other. The inlet of the connecting pipe is inserted into and communicates with the outlet end of the drain pipe. The outlet of the connecting pipe is detachably connected to the connecting pipe. The connecting pipe is fixed to the outer wall of the water injection tank and communicates with the inside of the water injection tank. Compared with the prior art, the retaining assembly, by connecting the connecting pipe to the drain pipe and fixing the connecting pipe to the water injection tank, and by detachably connecting the connecting pipe to the connecting pipe, ensures the stability of the drain pipe position (outlet end facing upwards) when not draining, and facilitates quick disassembly and switching to the draining state, improving the stability of the structure and ease of operation. The cooperation between the connecting pipe and the connecting pipe ensures a stable connection between the drain pipe and the water injection tank, preventing water leakage when not draining and ensuring the accuracy of water level observation.

[0012] In one possible implementation, the connecting pipe is inserted into the outlet, and the inner wall of the outlet mates with the outer wall of the connecting pipe. Compared with the prior art, the insertion of the connecting pipe into the outlet of the connecting pipe, with the outer and inner walls of both fitting together, enhances the connection strength between the connecting pipe and the connecting pipe in the assembly, preventing the drainage conduit from shifting due to loosening in non-drainage conditions, and ensuring the reliability of the water level observation function; the direct fit between the outer and inner walls reduces additional connecting parts and lowers structural complexity.

[0013] In one possible implementation, an annular groove is provided on the outer wall of the connecting pipe, and a sealing ring is embedded in the annular groove. The outer peripheral wall of the sealing ring fits against the inner wall of the outlet, and the inner peripheral wall of the sealing ring fits against the annular groove. Compared with the prior art, the annular groove and the sealing ring of the connecting pipe cooperate, with the sealing ring fitting against both the inner wall of the outlet and the annular groove, further improving the sealing performance between the connecting pipe and the connecting pipe, preventing water leakage when not draining, and ensuring the accuracy of water level observation.

[0014] In one possible implementation, the drain conduit is a cylindrical conduit, and the inlet of the connecting pipe is rotatably fitted onto the outlet end of the drain conduit. Compared with the prior art, the drain conduit is a cylindrical conduit, and the inlet of the connecting pipe is rotatably fitted onto its outlet end, allowing the connecting pipe to rotate relative to the drain conduit, making it more flexible to adjust the outlet position during drainage.

[0015] In one possible implementation, the valve core assembly includes a rotary valve core and a knob. The rotary valve core is rotatably disposed within the valve housing, and the knob is connected to the rotary valve core and extends outside the valve housing. The rotary valve core has a channel, one end of which communicates with a water outlet, and the other end of which communicates with a water inlet after being driven to rotate by the knob. Compared with the prior art, the valve core assembly achieves channel on / off control by driving the rotary valve core to rotate via a knob, making operation convenient and labor-saving.

[0016] This application also provides a chocolate mixer, including an overflow pipe and a drainage structure as described above. The inlet of the overflow pipe is connected to a heating boiler and located at the top of the heating boiler, and the outlet of the overflow pipe is connected to a water receiving tray of the chocolate mixer. The addition of the overflow pipe allows excess water to be drained to the water receiving tray when there is too much water in the heating boiler, preventing water overflow and contamination of the equipment or the external environment.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] See Figures 1 to 4 This application discloses a drainage structure, mainly composed of a heating boiler 1, a water injection tank 2, a drain pipe 3, a switch valve 4, a drain conduit 5, and a retaining assembly 6. The water injection tank 2 and the drain pipe 3 are both connected to the interior of the heating boiler 1, realizing the functions of water injection and drainage.

[0030] The on / off valve 4, as the core component controlling the flow of water, includes a valve body 41 and a valve core assembly 42. The valve body 41 is designed with mutually perpendicular inlet holes 411 and outlet holes 412. This vertical arrangement can effectively change the direction of water flow. The inlet hole 411 is rotatably fitted onto the outlet end of the drain pipe 3. This rotatable connection provides a basis for the subsequent turning of the drain pipe 5.

[0031] The inlet end of the drain pipe 5 is inserted into the outlet hole 412 of the valve housing 41, maintaining communication with the valve housing 41. Through the rotatable connection between the valve housing 41 and the drain pipe 3, the drain pipe 5 can rotate flexibly around the axis of the drain pipe 3, facilitating adjustment of the drainage direction. The drain pipe 5 is made of a transparent material, such as transparent plastic, and its length is greater than the water filling depth inside the heating boiler 1. This design allows for a direct visual assessment of the water level inside the pipe when not draining, thus determining the amount of water injected into the heating boiler 1.

[0032] The retaining component 6 is installed between the water injection tank 2 and the drain pipe 5. Its main function is to fix the outlet end of the drain pipe 5 upwards when not in the drainage state. In the drainage state, the operator can remove the drain pipe 5 from the retaining component 6, then rotate it around the axis of the drain connector 3 to a suitable angle, and then open the switch valve 4. At this time, the wastewater in the heating boiler 1 will pass through the drain connector 3 and the switch valve 4 in sequence, and finally be guided to the collection container by the drain pipe 5. In the non-drainage state, the outlet end of the drain pipe 5 is set upwards under the action of the retaining component 6. Using the transparent drain pipe 5, the operator can clearly observe the water level in the pipe, and thus accurately determine the amount of water injected into the heating boiler 1.

[0033] In this embodiment, the retaining component 6 includes a connecting pipe 61 and a connecting pipe 62. The connecting pipe 61 is provided with an inlet hole 611 and an outlet hole 612 that are interconnected. The inlet hole 611 of the connecting pipe 61 is inserted into and communicates with the outlet end of the drain pipe 5. The outlet hole 612 of the connecting pipe 61 is detachably connected to the connecting pipe 62. The connecting pipe 62 is fixed to the outer wall of the water injection tank 2 and communicates with the inside of the water injection tank 2.

[0034] Specifically, the connecting pipe 61 has an inlet 611 and an outlet 612 that are interconnected. The inlet 611 is inserted into and connected to the outlet end of the drain pipe 5 to ensure smooth water flow. The outlet 612 of the connecting pipe 61 is detachably connected to the connecting pipe 62, which facilitates the separation of the drain pipe 5 from the retaining assembly 6 during drainage. The connecting pipe 62 is fixed to the outer wall of the water filling tank 2 and communicates with the inside of the water filling tank 2. In this way, when not draining, the air pressure inside the drain pipe 5 is the same as the air pressure inside the heating boiler 1, making it easy to observe the water level.

[0035] In this embodiment, the connecting pipe 62 is inserted into the outlet hole 612, and the inner wall of the outlet hole 612 and the outer wall of the connecting pipe 62 cooperate with each other.

[0036] Specifically, this connection method ensures both the stability of the connection and the ease of pulling the connecting pipe 62 out of the outlet 612 when drainage is needed, making the operation convenient.

[0037] In this embodiment, to further enhance the sealing performance between the connecting pipe 62 and the outlet 612 of the connecting pipe 61, an annular groove is provided on the outer wall of the connecting pipe 62, and a sealing ring 621 is embedded in the annular groove. The outer peripheral wall of the sealing ring 621 fits tightly against the inner wall of the outlet 612, while the inner peripheral wall fits against the annular groove, effectively preventing leakage from the connection between the connecting pipe 62 and the outlet 612 in a non-drainage state, thus ensuring the sealing performance of the structure.

[0038] In this embodiment, the drain pipe 5 is a cylindrical pipe, and the inlet 611 of the connecting pipe 61 is rotatably sleeved on the outlet end of the drain pipe 5.

[0039] Specifically, this rotating connection allows the connecting pipe 61 to rotate freely relative to the drain pipe 5. When the drain pipe 5 rotates around the axis of the drain pipe 3 or the angle is adjusted, the connecting pipe 61 can rotate relative to the drain pipe 5, making it more flexible to adjust the water outlet position during drainage.

[0040] In this embodiment, the valve core assembly 42 includes a rotary valve core 421 and a knob 422. The rotary valve core 421 is rotatably disposed inside the valve housing 41. The knob 422 is connected to the rotary valve core 421 and extends out of the valve housing 41. The rotary valve core 421 is provided with a channel 4211. One end of the channel 4211 is connected to the water outlet 412, and the other end of the channel 4211 is connected to the water inlet 411 after being driven to rotate by the knob 422.

[0041] Specifically, the rotary valve core 421 is rotatably mounted inside the valve housing 41, and the knob 422 is connected to the rotary valve core 421 and extends outside the valve housing 41 for easy operation. The rotary valve core 421 has a channel 4211. In the initial state, one end of the channel 4211 is connected to the outlet hole 412. When the rotary valve core 421 is driven to rotate by the knob 422, the other end of the channel 4211 is connected to the inlet hole 411. At this time, the inlet hole 411 and the outlet hole 412 are connected through the channel 4211. Conversely, rotating the knob 422 disconnects the channel 4211 from the inlet hole 411. This simple rotational operation achieves the control of drainage flow.

[0042] like Figure 5 and Figure 6This application also provides a chocolate mixer, including an overflow pipe 10 and a drainage structure as described above. The inlet of the overflow pipe 10 is connected to a heating boiler 1 and is located at the top of the heating boiler 1. The outlet of the overflow pipe 10 is connected to a water receiving tray 20 of the chocolate mixer. When the water level in the heating boiler 1 exceeds a set height, water will flow out through the overflow pipe 10. The outlet of the overflow pipe 10 is connected to the water receiving tray 20 of the chocolate mixer, so that the overflowing water can be collected by the water receiving tray 20, preventing water from overflowing into other parts of the machine or the external environment, further ensuring environmental cleanliness and normal operation of the equipment.

[0043] The beneficial effects of this application include:

[0044] 1. Safe drainage: High-temperature wastewater is guided through a rotatable transparent drainage pipe 5, avoiding the risk of scalding and environmental pollution caused by irregular discharge, and significantly improving operational safety.

[0045] II. Water Level Visualization: In the non-drainage state, the drain pipe 5 is fixed by the retaining component 6 with the water outlet facing upward. Utilizing its transparency, the water level inside the pipe can be directly observed, and the water injection volume of the heating boiler 1 can be judged simultaneously, eliminating the need for an additional water level monitoring device.

[0046] III. Functional Integration and Convenient Switching: The drainage pipe 5 rotates around the axis of the drainage connector 3, and works with the switch valve 4 to quickly switch between drainage and non-drainage states. It has both drainage guidance and water level monitoring functions, simplifying the operation process.

[0047] IV. Structural stability and expandability: The connecting pipe 61 and the drainage pipe 5 are rotatably connected, which facilitates further adjustment of the drainage angle; an overflow pipe 10 is added to guide excess water from the boiler into the water receiving pan 20, which further prevents overflow water from contaminating the equipment.
