Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a cooking utensil. Background Art

[0002] The temperature measuring element is one of the indispensable and important components of cooking appliances. It is used to detect the temperature inside the cooking cavity in real time, and can also reflect the overflow situation through temperature detection. That is, the temperature inside the pot is detected by the temperature measuring element to determine whether the liquid in the pot is boiling. If the liquid boils violently, there is a risk of liquid overflowing from the steam valve. At this time, the temperature measuring element sends a signal to the control unit, and the control unit controls the heating device to stop heating.

[0003] In existing technology, a temperature sensor is typically located in the center of the pot lid and extends downward into the cooking cavity, directly contacting the air within the cooking cavity to detect temperature. However, in actual use, temperature differences exist in different areas of the cooking cavity, and the air distribution within the cooking cavity is relatively uneven. This can result in the temperature being measured in the area where the temperature sensor is located, failing to accurately reflect the temperature within the pot. Furthermore, the temperature sensor's detection sensitivity is affected, and there is a certain degree of lag in detection, making it difficult to accurately and quickly identify the temperature.

[0004] In addition, after the liquid inside the cooking chamber boils, a large amount of liquid flows up to the temperature measuring element, which can easily cause food to stick to the surface of the temperature measuring element, causing the temperature measuring element to be contaminated, seriously affecting the detection accuracy of the temperature measuring element.

[0005] At the same time, there is also a certain lag in using the temperature measuring component to detect the temperature inside the pot to determine the overflow situation. That is, after the liquid in the pot boils violently, foam and liquid rise quickly and overflow occurs, but the temperature measuring probe reacts slowly. Before the control unit stops the heating device, overflow has already occurred at the steam valve, so the anti-overflow effect is poor. Utility Model Content

[0006] The utility model provides a cooking utensil to solve the problems that a temperature measuring element arranged at the center of a pot cover has detection hysteresis, poor detection sensitivity and accuracy, and cannot effectively prevent pot overflow.

[0007] The technical solution adopted by this utility model is:

[0008] A cooking utensil includes a pot body and a pot lid, which cooperate to form a cooking cavity. The pot lid is provided with a steam valve and a temperature measuring element. The steam valve is provided with an air inlet facing the cooking cavity. At least a portion of the temperature measuring element extends into the cooking cavity through the air inlet. An annular bubble-breaking gap is formed between the outer peripheral side of the temperature measuring element and the edge of the air inlet.

[0009] The cooking utensil of the present invention also has the following additional technical features:

[0010] The steam valve has an exhaust cavity inside, and a rib protruding toward the exhaust cavity is provided at the air inlet. The rib surrounds the outer periphery of the air inlet and forms an air inlet channel, and the temperature measuring component extends into the air inlet channel.

[0011] The temperature measuring piece is fixed above the steam valve, and a through opening is provided on the top of the exhaust cavity. The temperature measuring piece extends into the exhaust cavity from the through opening and is sealed with the through opening.

[0012] The cooking appliance also includes an anti-overflow detection component arranged in the steam valve, which includes a first detection electrode and a second detection electrode arranged apart from the first detection electrode. When the first detection electrode and the second detection electrode are conductive, the anti-overflow detection component is triggered.

[0013] The temperature measuring element constitutes a first detection electrode, the second detection electrode is sleeved on the outer periphery of the temperature measuring element, and an insulating layer is provided between the second detection electrode and the temperature measuring element.

[0014] The outer periphery of the air inlet is provided with ribs protruding toward the inside of the steam valve. The lower edge of the insulating layer is higher than the lower edge of the temperature measuring component so that at least part of the insulating layer overlaps with the ribs in the height direction. The horizontal distance between the outer peripheral side of the insulating layer and the ribs is 2mm-6mm.

[0015] A rib protruding toward the inside of the steam valve is provided on the outer periphery of the air inlet, and the lower edge of the second detection electrode is higher than the upper edge of the rib.

[0016] The pot cover comprises a cover body and an inner cover detachably fixed to the cover body. The inner cover and the pot body cooperate to form a cooking cavity. The steam valve is fixed to the inner cover, and the temperature measuring piece is fixed to the cover body.

[0017] The steam valve includes a valve body and a valve cover. The valve body is fixed to the inner cover. The valve cover is detachably connected to the valve body. An air inlet is opened on the valve body. A passage for a temperature measuring component to pass through is provided on the valve cover corresponding to the air inlet.

[0018] The steam valve has an air outlet, an air inlet and an air outlet are staggered up and down, a steam retaining rib is provided between the air inlet and the air outlet, and an air gap is provided between the steam retaining rib and the inner wall of the steam valve.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0020] 1. In the present invention, a temperature measuring element extends from the air inlet of the steam valve into the cooking cavity. First, the temperature measuring element protruding into the cooking cavity can identify the ambient temperature within the cooking cavity, consistent with the function of the temperature measuring elements of existing products, without the need for major adjustments. Furthermore, regardless of the distribution of heat within the cooking cavity, the hot air will flow toward the steam valve and ultimately be discharged through the steam valve. Therefore, placing the temperature measuring element at the steam valve and detecting the temperature near the steam valve can more accurately determine the overall temperature within the pot. At the same time, the airflow at the air inlet is higher in temperature and has a faster flow rate, allowing the ambient temperature to be sensed more quickly by the temperature measuring element, improving detection accuracy and sensitivity.

[0021] Furthermore, the high-temperature, fast-flowing airflow passing through the air inlet flushes the temperature sensor, cleaning it with the hot gas. The impact of the airflow helps remove impurities adhering to the surface of the sensor. This enables the temperature sensor to self-clean during the exhaust process, ensuring a clean surface and ensuring detection accuracy and sensitivity while reducing the cleaning burden on the user.

[0022] Furthermore, the extension of the temperature sensor reduces the size of the air inlet, and an annular bubble-breaking gap is formed between the outer periphery of the temperature sensor and the rim of the air inlet. When airflow carrying bubbles and foam passes through the annular bubble-breaking gap, the temperature sensor and the rim of the air inlet squeeze the bubbles and foam, destroying larger bubbles and helping them burst. This facilitates gas-liquid separation, with airflow flowing upward into the steam valve and out, while the liquid formed by the bubble bursts flows downward back into the cooking chamber. The structural coordination of the temperature sensor and the steam valve allows rising bubbles to be broken, even if there is hysteresis in the overflow prevention detection, significantly reducing the risk of overflow.

[0023] 2. As a preferred embodiment of the present invention, the steam valve has an internal exhaust chamber, and a rib protruding toward the interior of the exhaust chamber is provided at the air inlet. The rib surrounds the outer periphery of the air inlet and forms an air inlet passage, into which a temperature measuring element extends. The rib forms an air inlet passage extending vertically within the exhaust chamber, and the temperature measuring element extends into the air inlet passage. This allows gas from the cooking chamber to enter the steam valve through the air inlet and first flow through the air inlet passage, within the gap between the rib and the temperature measuring element. This gap has a relatively small flow area. Therefore, after entering the air inlet, the airflow does not rapidly diffuse within the exhaust chamber, but instead flows around the temperature measuring element. This prolongs the contact time between the airflow and the temperature measuring element, ensuring sufficient contact between the temperature measuring element and the airflow to detect temperature, thereby improving detection accuracy. Furthermore, as bubbles in the airflow flow through the confined space, they continuously collide with the temperature measuring element and the rib, accelerating their rupture and thereby improving the bubble breaking effect.

[0024] 3. In a preferred embodiment of the present invention, the temperature-measuring element forms the first detection electrode, and the second detection electrode is sheathed around the outer periphery of the temperature-measuring element, with an insulating layer between the second detection electrode and the temperature-measuring element. In this embodiment, the temperature-measuring element is made of metal and forms the first detection electrode, enabling an integrated design of the overflow prevention detector and the temperature-measuring element, simplifying the lid structure and reducing costs.

[0025] 4. As a preferred embodiment of the present invention, the outer periphery of the air inlet is provided with a rib protruding toward the interior of the steam valve, and the lower edge of the second detection electrode is higher than the upper edge of the rib. The rib protrudes toward the interior of the steam valve, thereby forming an air inlet channel extending up and down inside the steam valve. Since the upper end of the air inlet channel is the outlet of the air inlet channel, even if liquid and foam rise into the air inlet channel, the risk of overflow is relatively small. Only when the liquid overflows from the air inlet channel and enters the cavity inside the steam valve does there exist a greater risk of overflow. Therefore, the second detection electrode is set to be higher than the upper edge of the rib, so that the liquid will not contact the second detection electrode until it overflows from the air inlet channel, thereby connecting the first detection electrode and the second detection electrode. At this time, the anti-overflow detection element sends a signal to the control unit to control the heating device to stop heating or reduce the heating power. In this way, on the basis of ensuring the anti-overflow effect, the timing of the anti-overflow detection element being triggered is appropriately delayed, so that the heating device can heat for a longer time and ensure heating efficiency.

[0026] 5. As a preferred embodiment of the present invention, the pot lid includes a lid body and an inner lid detachably fixed to the lid body. The inner lid and the pot body cooperate to form a cooking cavity. The steam valve is fixed to the inner lid, and the temperature measuring element is fixed to the lid body. The inner lid and the pot body cooperate to form a cooking cavity, which is in direct contact with the cooking environment in the pot and is more easily contaminated. The inner lid is detachably designed so that the user can remove the inner lid from the lid body and clean it separately, thereby improving the convenience of cleaning. At the same time, the steam valve is fixed to the inner lid so that it can be removed together with the inner lid, which also makes it convenient for the user to clean the inside of the steam valve and ensure the cleanliness of the steam valve. The temperature measuring element is fixed to the lid body and will not be removed together with the inner lid. Since the temperature measuring element needs to be connected to a wire, it is stably fixed to the lid body. On the one hand, it can prevent the wire from short-circuiting when it comes into contact with water. On the other hand, it can prevent the temperature measuring element from being frequently installed and removed, which may affect the connection stability of the wire, thereby ensuring a reliable and stable electrical connection.

[0042] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0046] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "implementation method", "embodiment", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0047] like Figure 1 、 Figure 2 、 Figure 3 As shown, a cooking utensil includes a pot body and a pot cover 1, the pot cover 1 and the pot body cooperate to form a cooking cavity, the pot cover 1 is provided with a steam valve 3 and a temperature measuring element 2, the steam valve 3 is provided with an air inlet 31 facing the cooking cavity, at least part of the area of ​​the temperature measuring element 2 extends into the cooking cavity through the air inlet 31, and an annular bubble breaking gap 21 is formed between the outer peripheral side of the temperature measuring element 2 and the edge of the air inlet 31.

[0048] In the present invention, the temperature measuring element 2 extends from the air inlet 31 of the steam valve 3 into the cooking cavity. First, the temperature measuring element 2 protruding into the cooking cavity can identify the ambient temperature within the cooking cavity, consistent with the function of the temperature measuring element 2 in existing products, without the need for major adjustments. Furthermore, regardless of the distribution of heat within the cooking cavity, the hot air will flow toward the steam valve 3 and ultimately be discharged through the steam valve 3. Therefore, by placing the temperature measuring element 2 at the steam valve 3 and detecting the temperature near the steam valve 3, the overall temperature within the pot can be more accurately determined. At the same time, the airflow at the air inlet 31 is higher in temperature and faster in flow rate, allowing the ambient temperature to be sensed more quickly by the temperature measuring element 2, thereby improving detection accuracy and sensitivity.

[0049] Specifically, such as Figure 2 As shown, the distance L1 between the lower end of the temperature measuring element 2 and the end surface where the air inlet 31 of the steam valve 3 is located is 4 mm to 8 mm, preferably 6 mm.

[0050] Furthermore, the high-temperature, fast-flowing airflow passing through the air inlet 31 can flush the temperature measuring element 2, thereby utilizing the high-temperature gas to clean the temperature measuring element 2. The impact of the airflow helps to remove impurities adhering to the surface of the temperature measuring element 2. This achieves a self-cleaning function for the temperature measuring element 2 during the exhaust process, ensuring a clean surface for the temperature measuring element 2, while maintaining detection accuracy and sensitivity, and reducing the cleaning burden on the user.

[0051] Furthermore, the extension of the temperature measuring element 2 reduces the size of the air inlet 31, and an annular bubble-breaking gap 21 is formed between the outer periphery of the temperature measuring element 2 and the edge of the air inlet 31. When the airflow carrying bubbles, foam, etc. passes through the annular bubble-breaking gap 21, the temperature measuring element 2 and the edge of the air inlet 31 can squeeze the bubbles and foam, thereby destroying larger bubbles and helping to break them. This facilitates gas-liquid separation, with the airflow upward entering the steam valve 3 and being discharged, while the liquid formed by the bubble breakage flows downward back into the cooking chamber. Thus, by utilizing the structural coordination of the temperature measuring element 2 and the steam valve 3, even if there is hysteresis in the overflow prevention detection, it is possible to break the rising bubbles, greatly reducing the risk of overflow.

[0052] Preferably, if Figure 2 As shown, the lower end of the temperature measuring element 2 is provided with an arc surface to guide the liquid on the surface of the temperature measuring element 2 to drip downwards, so as to avoid the liquid accumulating on the surface of the temperature measuring element 2 for a long time.

[0053] As a preferred embodiment of the present invention, Figure 2 、 Figure 8 As shown, the steam valve 3 has an exhaust cavity 32 inside, and a rib 311 protruding toward the inside of the exhaust cavity 32 is provided at the air inlet 31. The rib 311 surrounds the outer periphery of the air inlet 31 and forms an air inlet channel 312, and the temperature measuring component 2 extends into the air inlet channel 312.

[0054] The ribs 311 form an air inlet channel 312 extending vertically within the exhaust chamber 32, and the temperature measuring element 2 extends into the air inlet channel 312. This allows the gas in the cooking chamber to enter the steam valve 3 from the air inlet 31 and then flow through the gap between the ribs 311 and the temperature measuring element 2 within the air inlet channel 312. This gap has a relatively small flow area. Therefore, after entering the air inlet 31, the airflow does not diffuse rapidly within the exhaust chamber 32, but instead flows around the temperature measuring element 2. This prolongs the contact time between the airflow and the temperature measuring element 2, allowing the temperature measuring element 2 to fully contact the airflow to detect temperature, thereby improving detection accuracy. Furthermore, as bubbles in the airflow flow through the narrow space, they constantly collide with the temperature measuring element 2 and the ribs 311, accelerating their rupture and thus improving the bubble breaking effect.

[0055] Specifically, such as Figure 2 、 Figure 4 As shown, the temperature measuring element 2 is fixed above the steam valve 3 , and a through opening 33 is provided on the top of the exhaust cavity 32 . The temperature measuring element 2 extends into the exhaust cavity 32 from the through opening 33 and is sealed with the through opening 33 .

[0056] The temperature measuring element 2 and the steam valve 3 partially overlap in height. Specifically, during assembly, the temperature measuring element 2 passes through the steam valve 3 from above and exits from the air inlet 31. This makes the assembly of the temperature measuring element 2 and the steam valve 3 more compact, saves lateral size, and optimizes the structural layout of the pot lid 1.

[0057] Specifically, such as Figure 2 As shown, the top of the temperature measuring element 2 is provided with a fixed flange, which is fixed to the cover body 11 through the fixed flange. At the same time, the top of the temperature measuring element 2 is also provided with a sealing element 44. The sealing element 44 abuts against the top of the steam valve 3, thereby sealing the opening 33.

[0058] As a preferred embodiment of the present invention, Figure 2 As shown, the cooking appliance also includes an anti-overflow detection component 4 arranged in the steam valve 3. The anti-overflow detection component 4 includes a first detection electrode 41 and a second detection electrode 42 separated from the first detection electrode 41. When the first detection electrode 41 and the second detection electrode 42 are conductive, the anti-overflow detection component 4 is triggered.

[0059] When liquid or foam rises into the steam valve 3, it simultaneously contacts the first detection electrode 41 and the second detection electrode 42, thereby connecting them. This triggers the overflow prevention detector 4, which sends a signal to the control unit to stop heating or reduce the power of the heating device. This not only achieves overflow prevention detection for the cooking appliance, but also, by placing the overflow prevention detector 4 inside the steam valve 3, it can more accurately determine the overflow situation, thereby controlling the heating device to respond at the appropriate time. This prevents the heating device from stopping prematurely, which would lead to a decrease in heating efficiency, and avoids delayed response, which would lead to overflow.

[0060] In this embodiment, the conductivity of foam and liquid is utilized to make them contact with the first detection electrode 41 and the second detection electrode 42 at the same time to achieve conduction, thereby completing the triggering of the anti-overflow detection element 4. Of course, in other embodiments, the anti-overflow detection element 4 can also be of other structures and adopt other detection methods. For example, the anti-overflow detection element 4 can adopt a capacitance detection method. Specifically, the anti-overflow detection element 4 is a thin film structure, fixed to the inner wall or outer wall of the steam valve 3. The anti-overflow detection element 4 has multiple probe points, and there is an inductive capacitance between the probe points. When only gas passes through the steam valve 3, the inductive capacitance value between the probe points is a preset capacitance value. When bubbles, foam or liquid appear in the steam channel, the inductive capacitance between the probe points changes, which will transmit and convert the signal, and then convert the capacitance signal into a control signal of the control program, thereby achieving the function of controlling the smart device.

[0061] Further, if Figure 2 、 Figure 4 、 Figure 5 As shown, the temperature measuring element 2 forms a first detection electrode 41 , and the second detection electrode 42 is sleeved on the outer periphery of the temperature measuring element 2 , with an insulating layer 43 between the second detection electrode 42 and the temperature measuring element 2 .

[0062] In this embodiment, the temperature measuring element 2 is made of metal and forms the first detection electrode 41, enabling an integrated design of the overflow prevention detection element 4 and the temperature measuring element 2, simplifying the structure of the pot lid 1 and saving costs. Furthermore, the overflow prevention detection element 4 and the temperature measuring element 2 are integrally cylindrical, and their volume is minimal compared to that of the temperature measuring element 2, further contributing to the miniaturization of the overall detection assembly. Furthermore, there is no need to assemble each component separately; the overflow prevention detection element 4 can be first fixed to the temperature measuring element 2 and then assembled to the pot lid 1. This reduces assembly difficulty while also facilitating circuit connection and centralizing wiring locations, facilitating centralized wiring.

[0063] Preferably, the insulating layer 43 extends upward to above the steam valve 3 to extend the creepage distance and prevent the first detection electrode 41 and the second detection electrode 42 from being accidentally connected. Moreover, since there is no display panel blocking the steam valve 3, the insulating layer 43 can be passed upward out of the steam valve 3.

[0064] like Figure 2 As shown, the outer periphery of the air inlet 31 is provided with a rib 311 protruding toward the inside of the steam valve 3, and the lower edge of the insulating layer 43 is higher than the lower edge of the temperature measuring component 2, so that at least part of the insulating layer 43 overlaps with the rib 311 in the height direction, and the horizontal distance L2 between the outer peripheral side of the insulating layer 43 and the rib 311 is 2mm-6mm.

[0065] An annular circulation channel is formed between the outer periphery of the insulating layer 43 and the ribs 311. By limiting the width of the annular circulation channel, the insulating layer 43 and the ribs 311 can effectively squeeze bubbles in the gas while ensuring airflow efficiency, thereby improving bubble breaking. Preferably, the horizontal distance between the outer periphery of the insulating layer 43 and the ribs 311 is 4 mm.

[0066] Further, if Figure 2 As shown, a rib 311 protruding toward the inside of the steam valve 3 is provided on the outer periphery of the air inlet 31 , and the lower edge of the second detection electrode 42 is higher than the upper edge of the rib 311 .

[0067] The ribs 311 protrude toward the interior of the steam valve 3, thereby forming an air inlet channel 312 extending vertically inside the steam valve 3. Since the upper end of the air inlet channel 312 is the outlet of the air inlet channel 312, even if liquid and foam rise into the air inlet channel 312, the risk of overflow is relatively small. Only when the liquid overflows from the air inlet channel 312 and enters the cavity inside the steam valve 3, there is a greater risk of overflow. Therefore, the second detection electrode 42 is set to be higher than the upper edge of the ribs 311, so that the liquid will not contact the second detection electrode 42 until it overflows from the air inlet channel 312, thereby connecting the first detection electrode 41 and the second detection electrode 42. At this time, the anti-overflow detection element 4 sends a signal to the control unit to control the heating device to stop heating or reduce the heating power. In this way, on the basis of ensuring the anti-overflow effect, the timing of the anti-overflow detection element 4 being triggered is appropriately slowed down, so that the heating device can heat for a longer time and ensure heating efficiency.

[0068] As a preferred embodiment of the present invention, Figure 1 、 Figure 4 As shown, the pot cover 1 includes a cover body 11 and an inner cover 12 detachably fixed to the cover body 11 . The inner cover 12 and the pot body cooperate to form a cooking cavity. The steam valve 3 is fixed to the inner cover 12 , and the temperature measuring component 2 is fixed to the cover body 11 .

[0069] The inner lid 12 and the pot body form a cooking cavity, which comes into direct contact with the cooking environment within the pot and is therefore more susceptible to contamination. The inner lid 12 is detachable, allowing the user to remove it from the lid body 11 and clean it separately, improving cleaning convenience. The steam valve 3 is also fixed to the inner lid 12, allowing it to be removed along with the inner lid 12, making it easier for the user to clean the interior of the steam valve 3 and ensuring cleanliness. The temperature measuring element 2 is fixed to the lid body 11 and will not be removed along with the inner lid 12. Since the temperature measuring element 2 requires a wire connection, it is stably fixed to the lid body 11. This prevents the wire from short-circuiting due to water and prevents frequent installation and removal of the temperature measuring element 2, which could affect the stability of the wire connection, ensuring a reliable and stable electrical connection.

[0070] Further, if Figure 4 As shown, the steam valve 3 includes a valve body 35 and a valve cover 36. The valve body 35 is fixed to the inner cover 12. The valve cover 36 is detachably connected to the valve body 35. The air inlet 31 is opened in the valve body 35. The valve cover 36 is provided with a passage 33 for the temperature measuring component 2 to pass through at the position corresponding to the air inlet 31.

[0071] The valve cover 36 is detachably connected to the valve body 35, so that the user can open the steam valve 3 and clean the inside of the steam valve 3 more conveniently. Figure 4 As shown, the valve body 35 is fixed to the upper side of the inner cover 12. During assembly, the valve cover 36 is first fixed to the valve body 35. Then, the opening 33 on the valve cover 36 is aligned with the temperature measuring element 2 on the cover body 11. The temperature measuring element 2 is then passed through the steam valve 3 through the opening 33. During the assembly process, the temperature measuring element 2 and the opening 33 on the valve cover 36 can also be used to position the inner cover 12, thereby reducing installation difficulty and improving assembly efficiency.

[0072] Preferably, if Figure 6 、 Figure 7 As shown, the steam valve 3 has an air outlet 34, the air inlet 31 and the air outlet 34 are staggered up and down, and a steam retaining rib 37 is provided between the air inlet 31 and the air outlet 34, and an air gap 371 is provided between the steam retaining rib 37 and the inner wall of the steam valve 3.

[0073] Specifically, the lower edge of the steam retaining rib 37 is lower than the upper edge of the surrounding rib 311, so that after the air flows out from the upper end of the surrounding rib 311, it is blocked by the steam retaining rib 37 and can only flow downward, and then flows to the air outlet 34 through the air gap 371 below the steam retaining rib 37. This further lengthens the flow path of the air flow inside the steam valve 3, causing bubbles to burst during the flow process, thereby reducing the risk of liquid overflow.

[0074] Specifically, such as Figure 9As shown, the bottom of the steam valve 3 is also provided with a reflux port 39. Liquid generated by the bursting of bubbles within the steam valve 3 drips into the cooking chamber through the reflux port 39. The inner bottom wall of the steam valve 3 is provided with a guide slope 38 that gradually descends toward the reflux port 39, so that the liquid can be discharged in a timely manner without accumulating inside the steam valve 3.

[0075] Anything not described in this utility model can be achieved by adopting or drawing on existing technologies.
