Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to an electric steamer. Background Technology

[0002] An electric steamer is a household kitchen appliance that uses electric heating to steam food. Electric steamers with a water control function typically have a water control tank located below the main water tank. This tank contains a water control valve that regulates the water level in the steam generator. After use, some water usually remains in the water control tank, requiring the entire steamer to be turned upside down to drain the excess water, which is inconvenient. Utility Model Content

[0003] Therefore, it is necessary to provide an electric steamer that can conveniently treat residual wastewater.

[0004] An electric steamer includes a base, a water tank, and a cooking body. Both the water tank and the cooking body are mounted on the base. The base includes a steam generator, a water control tank, a water collection box, and an operating component. The steam generator produces steam to supply the cooking body. The water control tank is located between the water tank and the steam generator. The water control tank contains a water control valve for controlling the water level in the steam generator. The bottom of the water control tank has a drain outlet with a drain valve. The water collection box is located below the drain outlet. The operating component includes a control for controlling the opening and closing of the drain valve. The water tank is detachably mounted on the base. When the water tank is mounted on the base, it can conceal the control component; when the water tank is removed from the base, the control component is exposed.

[0005] The electric steamer provided in this application allows for easy cleaning of residual wastewater. When residual wastewater remains in the water tank, the drain valve can be opened via a control unit, allowing the wastewater to drain into the water collection box. The collection box can then be removed and the water poured out, completing the cleaning process without needing to invert the base, making it very convenient. Furthermore, when the water tank is installed on the base, it obstructs the control unit, preventing the user from accessing it and avoiding accidental opening of the drain valve during use. After cooking, simply removing the water tank allows operation of the control unit to open the drain valve, making it extremely convenient and easy to use.

[0006] In one embodiment, the water control tank is located below the water storage tank; or, the steam generator, the water control tank, and the water storage tank are arranged side by side in a horizontal direction.

[0007] The water control tank is located below the water storage tank. Thus, when the water control valve is opened, water in the storage tank flows into the water control tank under gravity, and then flows through the water control tank to the steam generator. The structure is relatively simple. The steam generator, water control tank, and water storage tank are arranged side-by-side horizontally, further simplifying the structure and facilitating base assembly.

[0008] In one embodiment, the lowest point of the inner cavity of the water control tank is not higher than the lowest point of the inner cavity of the steam generator and the lowest point of the inner cavity of the water storage tank.

[0009] In this way, the residual wastewater in the steam generator can flow into the water control tank, and similarly, the residual wastewater in the water storage tank can also flow into the water control tank, so that the residual wastewater in the electric steamer can be discharged in a concentrated manner through the drain outlet of the water control tank.

[0010] In one embodiment, the drain outlet is located at the lowest point of the inner cavity of the water control tank.

[0011] In this way, the residual wastewater in the water control tank can automatically flow to the drain outlet under the action of gravity, so that the residual wastewater can be discharged into the water collection box when the drain valve is opened.

[0012] In one embodiment, the base is provided with an installation channel, and the operating component further includes an operating part and a transmission component. The operating part is movably disposed within the installation channel, and the control component can control the up-and-down movement of the operating part. The transmission component is at least partially disposed within the water receiving box, and the operating part controls the opening and closing of the drain valve through the transmission component.

[0013] Thus, the control unit only needs to control the up-and-down movement of the operating part to control the opening and closing of the drain valve 60, making the control method very simple. Furthermore, by incorporating a transmission component, the installation position of the operating part can be set more flexibly.

[0014] In one embodiment, the base has a mounting position, the water tank is detachably mounted on the mounting position, the mounting channel is located below the mounting position and communicates with the mounting position, and the control component is a button, which is integrally formed on the top of the operating part, or the button is connected to the top of the operating part.

[0015] Thus, pressing the button downwards will move the control unit downwards, making operation very simple.

[0016] In one embodiment, the transmission component is rotatably disposed in the water receiving box via a rotating shaft. The transmission component has a first transmission part and a second transmission part on both sides of the rotating shaft, respectively. The operating part corresponds to the first transmission part and is used to control the movement of the first transmission part. The second transmission part corresponds to the drain valve and is used to control the operation of the drain valve.

[0017] Thus, the transmission component is mounted on the water receiving box. When the base is not equipped with the water receiving box, or the water receiving box is not properly installed, the up-and-down movement of the operating part cannot control the movement of the transmission component. This avoids the situation where the drain valve is opened due to accidental operation of the operating part when the water receiving box is not installed or is not properly installed. In this embodiment, the transmission component can transmit the movement of the operating part to the drain valve by rotating around the pivot, thereby controlling the operation of the drain valve. The transmission component has a simple structure and is easy to control.

[0018] In one embodiment, the drain valve includes a valve core that can move up and down and a second elastic member sleeved on the valve core. In its natural state, the valve core closes the drain valve under the action of the second elastic member. When the operating part moves downward and drives the first transmission part to move downward, the second transmission part moves upward and can push the valve core upward to open the drain valve.

[0019] Thus, the drain valve can be opened simply by moving the control unit downwards, making operation very simple. When the second transmission unit moves downwards, the thrust that moves the valve core upwards is removed. Under the elastic force of the second elastic element, the valve core can automatically reset, thereby automatically closing the drain valve and ensuring the reliability of the drain valve opening and closing control.

[0020] In one embodiment, in the natural state, the distance between the highest point of the first transmission part and the bottom wall of the water receiving box is H5, the distance between the highest point of the second transmission part and the bottom wall of the water receiving box is H6, and the distance between the highest point of the water receiving box and the bottom wall of the water receiving box is H, where H6≤H5≤H.

[0021] This ensures that the transmission components will not interfere with the base when installing or removing the water collection box, thus preventing difficulties in placing or removing the water collection box.

[0022] In one embodiment, the inner wall of the drain outlet is provided with a sealing rib, and the valve core includes a rod, a sealing part, and a stop part. The rod passes through the drain outlet, and the sealing part and the stop part are both provided on the outer wall of the rod, and the sealing part and the stop part are respectively located on the upper and lower sides of the sealing rib. When the sealing part abuts against the sealing rib, the drain outlet is closed; when the sealing part disengages from the sealing rib, the drain outlet is opened. The second elastic member is sleeved on the rod, and its two ends abut against the sealing rib and the stop part respectively, so that the sealing part abuts against the sealing rib.

[0023] Thus, the stop part is subjected to the downward elastic force of the second elastic member, causing the sealing part to tend to move downward and abut against the upper side of the sealing baffle, thereby closing the drain valve. When the second transmission part moves upward and pushes against the valve core, the stop part moves upward and compresses the second elastic member, while the sealing part moves upward and disengages from the sealing baffle, thereby opening the drain valve, allowing water in the control tank to flow into the water receiving box through the drain port. When the second transmission part moves downward and away from the valve core, under the elastic force of the second elastic member, the sealing part abuts against the upper side of the sealing baffle again, thereby closing the drain valve again. It can be seen that the drain valve structure of this embodiment is very simple.

[0024] In one embodiment, the drain valve includes a valve core that can move up and down, the up and down movement of the valve core can control the opening and closing of the drain valve, the transmission member is configured as a U-shaped member, one end of the U-shaped member is connected to the bottom end of the operating part, and the other end is used to drive the valve core to move up and down. When the operating part moves down and drives the U-shaped member to move down, the valve core moves down to open the drain valve.

[0025] In this way, the up-and-down movement of the valve core and the up-and-down movement of the operating part are synchronized, making the structure simpler and the control easier.

[0026] In one embodiment, the outer wall of the operating part is provided with a first limiting part, the inner wall of the mounting channel is provided with a limiting rib, the limiting rib is located below the first limiting part, and the operating component is also provided with a first elastic member, the first elastic member abutting between the first limiting part and the limiting rib.

[0027] Thus, when the operating part is pressed down or when the operating part moves downward under the drive of the electric drive member, the first limiting part can compress the first elastic member; when the downward force applied to the operating part is removed, the first elastic member can push the first limiting part upward, thereby causing the operating part to move upward, so that the operating part can achieve automatic reset.

[0028] In one embodiment, the outer wall of the operating part is further provided with a second limiting part, which is located below the limiting rib. When the operating part is in the reset state, the second limiting part abuts against the limiting rib.

[0029] Thus, when the downward force acting on the operating part is removed, under the elastic force of the first elastic member, the first limiting part drives the operating part to move upward, thereby automatically resetting the operating part. At this time, the second limiting part abuts against the lower end of the limiting rib. The setting of the second limiting part can prevent the operating part from falling out of the installation channel. Attached Figure Description

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0048] Please see Figures 1 to 4 This application provides an electric steamer, including a base 10, a water tank 30, and a cooking body 20. Both the water tank 30 and the cooking body 20 are mounted on the base 10. The base 10 includes a steam generator 11, a water control tank 41, a water collection box 70, and operating components. The steam generator 11 generates steam to supply the cooking body 20. The water control tank 41 is located between the water tank 30 and the steam generator 11, and contains a water control valve 42 for controlling the water level in the steam generator 11. The bottom of the water control tank 41 has a drain outlet 411 with a drain valve 60. The water collection box 70 is located below the drain outlet 411. Thus, when the drain valve 60 is opened, water in the water control tank 41 can flow into the water collection box 70. The operating components include a control element 513 for controlling the opening and closing of the drain valve 60. Thus, when there is residual wastewater in the water control tank 41, the drain valve 60 can be opened by controlling the control component 513 of the operating component, so that the residual wastewater in the water control tank 41 can be discharged into the water receiving box 70. Then the water receiving box 70 can be removed and the water poured out. This completes the cleaning of residual wastewater. The entire cleaning process does not require the base 10 to be completely inverted, which is very convenient.

[0049] Furthermore, the water tank 30 is detachably mounted on the base 10. When the water tank 30 is mounted on the base 10, it conceals the control component 513; when the water tank 30 is removed from the base 10, the control component 513 is exposed. Thus, when the water tank 30 is mounted on the base 10, it conceals the control component 513, preventing the user from accessing it and avoiding accidental opening of the drain valve 60 during use. After cooking, simply removing the water tank 30 allows operation of the control component 513 to open the drain valve 60 for drainage, making it very convenient and easy to use.

[0050] It is understandable that the cooking body 20 has a cooking cavity 21, and the steam generator 11 is located below the cooking cavity. The steam generated by the steam generator 11 can enter the cooking cavity 21 to cook food. Figure 2 As shown, in one embodiment, the cooking body 20 includes a pot lid, and a cooking cavity 21 is formed inside the pot lid. A steaming rack can be installed inside the cooking cavity 21 to support the food being steamed. In addition, in other embodiments, the cooking body 20 may also include a steamer, with the cooking cavity 21 formed inside the steamer, or the steamer and the pot lid enclose the cooking cavity 21. This application does not limit this, as long as the cooking body 20 has a cooking cavity 21 that can accommodate food.

[0051] The steam generator 11 may only have a first heat source 12 to heat water and generate steam, which is then directly delivered to the cooking cavity 21 of the cooking body 20. Alternatively, the steam generator 11 may have a second heat source 13 in addition to the first heat source 12 to heat the steam generated from the water to form high-temperature steam before delivering it to the cooking cavity 21 of the cooking body 20. This application does not impose any restrictions on this, as long as the steam generator 11 can generate steam and deliver it to the cooking cavity 21 of the cooking body 20.

[0052] In one embodiment, the steam generator 11 and the water control tank 41 are always connected, and the water control valve 42 can supply water to the steam generator 11 by controlling the water storage tank 30 to supply water to the water control tank 41.

[0053] Furthermore, such as Figure 2 As shown, in one embodiment, the water control tank 41 is located below the water storage tank 30. Thus, when the water control valve 42 is opened, water in the water storage tank 30 flows into the water control tank 41 under gravity, and then flows through the water control tank 41 into the steam generator 11. The structure is relatively simple. Please refer to... Figure 3In one embodiment, the water control valve 42 is configured as a float valve, the water control tank 41 has an inlet 412, and the water storage tank 30 is connected to the water control tank 41 through the inlet 412. The float valve is used to control the opening and closing of the inlet 412. This float valve can control the water level in the steam generator 11 below a preset water level line A. Specifically, when the water level in the steam generator 11 drops below the preset water level line A, the float valve drops to the position of opening the inlet 412, allowing water in the water storage tank 30 to flow into the water control tank 41 and then into the steam generator 11, thereby replenishing water to the steam generator 11 through the water storage tank 30 and causing the water level in the steam generator 11 to rise. When the water level in the steam generator 11 rises above the preset water level line A, the float valve rises to the position of closing the inlet, isolating the water storage tank 30 and the water control tank 41, so that the water storage tank 30 will not replenish water to the steam generator 11. The float valve can directly cooperate with the inlet 412 to open and close the inlet 412; alternatively, the float valve can cooperate with the inlet 412 via a lever structure. The rise and fall of the float valve drives the lever structure to rotate, and the sealing component on the lever structure opens and closes the inlet 412. This application does not limit the cooperation structure between the float valve and the inlet 412, as long as the rise and fall of the float valve can control the opening and closing of the inlet 412. The float valve control method is simple and can keep the water level in the steam generator 11 always below the preset water level line A. Of course, the water control valve 42 can also be a water control valve of other structures, as long as it can achieve water level control and keep the water level in the steam generator 11 always below the preset water level line A. This application does not impose any restrictions on this.

[0054] like Figure 11 As shown, in another embodiment, the steam generator 11, the water control tank 41, and the water storage tank 30 are arranged side by side in a horizontal direction. This results in a simpler structure and easier assembly of the base 10. In this embodiment, the water control valve 42 can be an electrically controlled valve. The amount of water supplied from the water storage tank 30 to the steam generator 11 is controlled by adjusting the opening degree and duration of the water control valve 42. A water level sensor can be installed inside the steam generator 11. The water level sensor detects the water level inside the steam generator 11, thereby controlling the opening and closing of the water control valve 42 to ensure that the water level inside the steam generator 11 is always kept below the preset water level line A. Of course, the water control valve 42 can also be a water control valve of other structures, as long as it can achieve water level control and keep the water level inside the steam generator 11 always below the preset water level line A. This application does not impose any limitations on this.

[0055] Furthermore, the lowest point of the inner cavity of the water control tank 41 is not higher than the lowest point of the inner cavity of the steam generator 11 and the lowest point of the inner cavity of the water storage tank 30. In this way, the residual wastewater in the steam generator 11 can flow into the water control tank 41. Similarly, the residual wastewater in the water storage tank 30 can also flow into the water control tank 41, so that the residual wastewater in the electric steamer can be discharged in a concentrated manner through the drain port 411 of the water control tank 41.

[0056] Furthermore, the drain outlet 411 is located at the lowest point of the inner cavity of the water control tank 41. In this way, the residual wastewater in the water control tank 41 can automatically flow to the drain outlet 411 under the action of gravity, so that the residual wastewater can be discharged into the water receiving box 70 when the drain valve 60 is opened.

[0057] Further, please see Figure 2 and Figure 3 The inner bottom wall of the water control tank 41 is higher than, lower than, or flush with the inner bottom wall of the steam generator 11. When the inner bottom wall of the water control tank 41 is higher than the inner bottom wall of the steam generator 11, the height difference between the inner bottom wall of the water control tank 41 and the inner bottom wall of the steam generator 11 is H1, and H1 ≤ 5mm. This ensures that the water in the water control tank 41 can flow smoothly into the steam generator 11.

[0058] Furthermore, the capacity of the water receiving box 70 is V1, the capacity of the steam generator 11 below the preset water level line A is V2, and the capacity of the water control tank 41 below the preset water level line A is V3, where 1.05(V2+V3)≤V1≤5(V2+V3). It is understood that after cooking, the maximum amount of residual wastewater in the electric steamer is V2+V3. This configuration ensures that the water receiving box 70 can hold all the residual wastewater, and that the wastewater is not easily spilled when the water receiving box 70 is removed.

[0059] Furthermore, the base 10 is provided with an installation channel 15, and the operating components include an operating part 50 and a transmission component 80. The operating part 50 is movably disposed within the installation channel 15, and the control component 513 can control the up-and-down movement of the operating part 50. The transmission component 80 is at least partially disposed within the water receiving box 70, and the operating part 50 controls the opening and closing of the drain valve 60 via the transmission component 80. Thus, the control component 513 only needs to control the up-and-down movement of the operating part 50 to control the opening and closing of the drain valve 60, making the control method very simple. Moreover, by providing the transmission component 80, the installation position of the operating part 50 can be set more flexibly.

[0060] Furthermore, the base 10 is provided with a mounting position 14, and the water storage tank 30 is detachably mounted on the mounting position 14. The mounting channel 15 is located below the mounting position 14 and communicates with the mounting position 14. The control component 513 is set as a button, which is integrally formed on the top of the operating part 50, or the button is connected to the top of the operating part 50. In this way, pressing the button downwards will move the operating part 50 downwards, making the operation very simple. When the button and the operating part 50 are two independent components, the button and the operating part 50 can be detachably connected or non-detachably connected. Furthermore, the button and the operating part 50 can be fixedly connected or movably connected. This application does not limit this, as long as the button is connected to the top of the operating part 50 and pressing the button can control the operating part 50 to move downwards.

[0061] In this embodiment, the control element 513 is configured as a button, which is a mechanical control structure. However, it is not limited to this; the control element 513 can also be configured as a knob or other types of mechanical control structures, as long as the control element 513 can control the up-and-down movement of the operating part 50. Mechanical control structures do not require electricity, are not limited by power on / off conditions, are energy-saving and environmentally friendly, and are easy to operate. However, it is not limited to this; the control element 513 can also be an electronic control structure, such as an electronic switch. It is understood that when the control element 513 is an electronic switch, the operating components also include an electric drive element. The electronic switch is used to control the opening and closing of the electric drive element, and the electric drive element controls the up-and-down movement of the operating part 50. The electric drive element can be a motor or an electromagnet, etc., and this application does not limit this, as long as the electric drive element can control the operation of the operating part under the action of electricity.

[0062] In this embodiment, the operating part 50 is a rod, and the control part 513 is integrally formed on the top of the operating part 50. Please refer to [link / reference]. Figure 3 and Figure 4 The upper end of the mounting channel 15 is provided with a positioning groove 153, the inner diameter of which is larger than the inner diameter of the mounting channel 15. The outer diameter of the control component 513 is smaller than the inner diameter of the positioning groove 153 but larger than the inner diameter of the mounting channel 15. Thus, when the control component 513 is pressed downwards, it can only move to the bottom wall of the positioning groove 153 at most, thereby limiting its travel and preventing it from getting stuck in the mounting channel 15. Furthermore, this design of the control component 513 increases the pressure-bearing area, making it easier to manually press the control component 513.

[0063] In this embodiment, the bottom wall of the water storage tank 30 is provided with a positioning part 31. When the water storage tank 30 is installed on the base 10, the positioning part 31 extends into the positioning groove 153. The cooperation between the positioning part 31 and the positioning groove 153 enables the water storage tank 30 to be quickly positioned, thereby facilitating the quick installation of the water storage tank 30 onto the base 10. The outer diameter of the control component 513 is L3, and the positioning part 31 is an annular rib with an inner diameter of L4, where L4 > L3. Thus, when installing the water storage tank 30, the control component 513 is located inside the positioning part 31, avoiding interference between the positioning part 31 and the control component 513, which would affect the normal installation of the water storage tank 30.

[0064] Please see Figures 3 to 6 In one embodiment, the transmission component 80 is rotatably mounted within the water receiving box 70 via a rotating shaft 83. The transmission component 80 has a first transmission part 81 and a second transmission part 82 on both sides of the rotating shaft 83. An operating part 50 corresponds to the first transmission part 81 and is used to control its movement. The second transmission part 82 corresponds to the drain valve 60 and is used to control its operation. Thus, when the transmission component 80 is mounted on the water receiving box 70, if the base 10 is not equipped with the water receiving box 70, or if the water receiving box 70 is not properly installed, the up-and-down movement of the operating part 50 cannot control the movement of the transmission component 80. This avoids the situation where the drain valve 60 opens due to misoperation when the water receiving box 70 is not installed or is not properly installed. In this embodiment, the transmission component 80 can transmit the movement of the operating part 50 to the drain valve 60 by rotating around the rotating shaft 83, thereby controlling the operation of the drain valve 60. The transmission component 80 has a simple structure and is easy to control.

[0065] Furthermore, the drain valve 60 includes a valve core 61 that can move up and down and a second elastic element 62 sleeved on the valve core 61. In its natural state (i.e., when the transmission member 80 does not apply external force to the valve core 61), the valve core 61 closes the drain valve 60 under the action of the second elastic element 62. When the operating part 50 moves downward and drives the first transmission part 81 to move downward, the second transmission part 82 moves upward and can push the valve core 61 upward to open the drain valve 60. Thus, the drain valve 60 can be opened simply by controlling the operating part 50 to move downward, making the operation very simple. When the second transmission part 82 moves downward, the thrust that caused the valve core 61 to move upward is removed. Under the elastic force of the second elastic element 62, the valve core 61 can automatically reset, thereby the drain valve 60 can automatically close, ensuring the reliability of the opening and closing control of the drain valve 60. In one embodiment, the second elastic element 62 is a spring, which has a simple structure and is easy to install.

[0066] Furthermore, the inner wall of the drain outlet 411 is provided with a sealing rib 4111. The valve core 61 includes a rod portion 611, a sealing portion 612, and a stop portion 613. The rod portion 611 passes through the drain outlet 411. The sealing portion 612 and the stop portion 613 are both located on the outer wall of the rod portion 611, and the sealing portion 612 and the stop portion 613 are located on the upper and lower sides of the sealing rib 4111, respectively. When the sealing portion 612 abuts against the sealing rib 4111, the drain outlet 411 is closed, that is, the drain valve 60 is closed. Figure 4 As shown; when the sealing part 612 disengages from the sealing baffle 4111, the drain port 411 opens, that is, the drain valve 60 opens, as shown. Figure 6 As shown. The second elastic member 62 is sleeved on the rod portion 611, and its two ends abut against the sealing rib 4111 and the stop portion 613 respectively, so that the sealing portion 612 abuts against the sealing rib 4111. In this way, the stop portion 613 is subjected to the downward elastic force of the second elastic member 62, so that the sealing portion 612 has a downward tendency to move and abut against the upper side of the sealing rib 4111, thereby closing the drain valve 60. When the second transmission part 82 moves upward and pushes the valve core 61, the stop portion 613 moves upward and compresses the second elastic member 62, while the sealing portion 612 moves upward and disengages from the sealing rib 4111, thereby opening the drain valve 60, as shown. Figure 6 As shown, the water in the water tank 41 can flow into the water receiving box 70 through the drain port 411. When the second transmission member 80 moves downward away from the valve core 61, under the elastic force of the second elastic member 62, the sealing part 612 abuts against the upper side of the sealing baffle 4111 again, thereby closing the drain valve 60 again. Figure 4 As shown, the drain valve 60 in this embodiment has a very simple structure.

[0067] Please see Figure 4 and Figure 8 Furthermore, the stop portion 613 is a raised rib integrally formed on the rod portion 611, and the sealing portion 612 is a sealing ring installed on the outer wall of the rod portion 611. Thus, the sealing portion 612 is detachable, facilitating the installation of the second elastic element 62 on the outside of the rod portion 611 and the installation of the drain valve 60 on the drain outlet 411. In this embodiment, the outer wall of the rod portion 611 is provided with a groove 6112, and the sealing portion 612 is a silicone sealing ring installed in the groove 6112. This facilitates installation and provides a good sealing effect.

[0068] Further, please see Figure 8 and Figure 9The stop portion 613 has multiple notches 6131 along its circumferential direction. The total flow area of ​​the notches 6131 is S1, and the cross-sectional area of ​​the stop portion 613 in the direction perpendicular to the axial direction of the rod portion 611 is S2, where 30% ≤ S1 / S2 ≤ 80%. This ensures that when the drain outlet 411 is opened, the water in the water control tank 41 can flow smoothly down through the notches 6131 on the stop portion 613, reducing the waiting time for drainage and ensuring that the stop portion 613 has sufficient strength to support the second elastic member 62. It can be understood that the "total flow area of ​​the notches 6131" refers to the sum of the cross-sectional areas of the notches 6131 in the direction perpendicular to the water flow, and the "cross-sectional area of ​​the stop portion 613 in the direction perpendicular to the axial direction of the rod portion 611" includes the total flow area of ​​the notches 6131 and the cross-sectional area of ​​the portion without notches 6131. In this embodiment, the stop portion 613 is a ring structure provided on the outer wall of the rod portion 611, and the "cross-sectional area of ​​the stop portion 613" refers to the area of ​​the ring. Of course, the stop portion 613 can also be other shapes. In this embodiment, the stop portion 613 is provided with four notches 6131, but it is not limited to this, and the number of notches 6131 can also be other numbers.

[0069] Please see Figure 3 and Figure 4 The transmission component 80 is inclined under its own weight, with the end of the transmission component 80 having the first transmission part 81 higher than the end having the second transmission part 82. This ensures that when the operating part 50 moves downward, the first transmission part 81 moves upward, causing the transmission component 80 to rotate around the rotating shaft 83, which in turn causes the second transmission part 82 to move upward, thereby lifting the valve core 61 and opening the drain valve 60. This structural arrangement in this embodiment reduces the travel of the operating part 50, which helps improve the stability of the movement of the transmission component 80 and the valve core 61 of the drain valve 60.

[0070] Assuming the weight of the first transmission component 80 is G1 and the torque length of the first transmission component 80 is L1, and the weight of the second transmission component 80 is G2 and the torque length of the second transmission component 80 is L2, then G1*L1 < G2*L2 is satisfied. In this way, it is ensured that the transmission component 80 is tilted under its own weight, and the end of the transmission component 80 with the first transmission part 81 is higher than the end with the second transmission part 82.

[0071] Please see Figure 3 The effective stroke of the operating part 50 is H3. In its natural state, the distance between the lower end of the operating part 50 and the highest point of the first transmission part 81 is H4, and the distance between the highest point of the second transmission part 82 and the lowest point of the valve core 61 is H7. H3 > H4 + H7, ensuring that the downward movement of the operating part 50 can drive the first transmission part 81 to move downward, thereby causing the transmission member 80 to rotate around the rotating shaft 83. The second transmission part 82 moves upward and can push the valve core 61 to move upward, thereby opening the drain port 411.

[0072] Further, please see Figure 3 In its natural state, the distance between the highest point of the first transmission part 81 and the inner bottom wall of the water receiving box 70 is H5, the distance between the highest point of the second transmission part 82 and the inner bottom wall of the water receiving box 70 is H6, and the distance between the highest point of the water receiving box 70 and the inner bottom wall of the water receiving box 70 is H, where H6≤H5≤H. This ensures that when installing or removing the water receiving box 70, the transmission part 80 will not interfere with the base 10, thus preventing difficulty in placing or removing the water receiving box 70.

[0073] Please combine Figure 7 As shown, in this embodiment, the transmission component 80 is configured as a plate-like structure. Furthermore, through holes can be provided on the transmission component 80 to ensure that water above the transmission component 80 can flow smoothly down, thereby ensuring that the end of the transmission component 80 with the first transmission part 81 remains higher than the end with the second transmission part 82 under its own weight. Please refer to... Figure 4 and Figure 7 The first transmission part 81 is disposed on the edge of the transmission member 80. The first transmission part 81 includes a first protrusion 811 and a first columnar rod 812 disposed above the first protrusion 811. The second transmission part 82 includes a second protrusion 821, a second columnar rod 822 disposed above the second protrusion 821 and a third columnar rod 823 disposed below the second protrusion 821, thereby increasing the weight of the second transmission part 82.

[0074] Furthermore, the transmission component 80 is detachably installed on the water receiving box 70, so that the transmission component 80 can be removed for cleaning.

[0075] Please see Figure 10 In another embodiment, the drain valve 60 includes a valve core 61 that can move up and down. The up-and-down movement of the valve core 61 controls the opening and closing of the drain valve 60. The transmission member 80 is configured as a U-shaped member, one end of which is connected to the bottom end of the operating part 50, and the other end is used to drive the valve core 61 to move up and down. When the operating part 50 moves downward and drives the U-shaped member downward, the valve core 61 moves downward to open the drain valve 60. It can be understood that when the operating part 50 moves upward and drives the U-shaped member upward, the valve core 61 moves upward to close the drain valve 60. Therefore, the up-and-down movement of the valve core 61 and the up-and-down movement of the operating part 50 are synchronized, resulting in a simpler structure and easier control. The structure of the drain valve 60 in this embodiment can be referred to... Figure 4 and Figure 6In the illustrated embodiment, the position of the sealing part and the sealing rib is adjusted so that the drain valve 60 opens when the valve core 61 moves downward and closes when the valve core 61 moves upward. The specific structure of the drain valve 60 is not described in detail here. In this embodiment, the transmission component 80 can be connected to the operating part 50 by means of snap-fit, threaded connection, fastener connection, etc., and this application does not impose any restrictions on this.

[0076] This application controls the opening and closing of the drain valve 60 by the up-and-down movement of the operating part 50. Please see [link / reference]. Figure 4 and Figure 6 Furthermore, the outer wall of the operating part 50 is provided with a first limiting part 511, and the inner wall of the mounting channel 15 is provided with a limiting rib 151. The limiting rib 151 is located below the first limiting part 511. The operating component is also provided with a first elastic member 52, which abuts against the first limiting part 511 and the limiting rib 151. Thus, when the operating part 50 is pressed down or when the operating part 50 moves downward under the drive of the electric drive member, such as Figure 6 As shown, the first limiting part 511 can compress the first elastic member 52; when the downward force applied to the operating part 50 is removed, the first elastic member 52 can push the first limiting part 511 upward, thereby causing the operating part 50 to move upward, thus enabling the operating part 50 to automatically reset, as shown. Figure 4 As shown. In one embodiment, the first elastic element 52 is a spring, which is sleeved on the outside of the operating part 50. The structure is simple and easy to install.

[0077] Please see Figure 4 Furthermore, the outer wall of the operating part 50 is also provided with a second limiting part 512. The second limiting part 512 is located below the limiting rib 151. When the operating part 50 is in the reset state, the second limiting part 512 abuts against the limiting rib 151. Thus, when the downward force acting on the operating part 50 is removed, under the elastic force of the first elastic member 52, the first limiting part 511 drives the operating part 50 to move upward, thereby automatically resetting the operating part 50. Figure 4 As shown, at this time, the second limiting part 512 abuts against the lower end of the limiting rib 151, and the setting of the second limiting part 512 can prevent the operating part 50 from coming out of the installation channel 15.

[0078] In this embodiment, the first limiting part 511 is a protruding rib integrally formed on the outer wall of the operating part 50, and the second limiting part 512 is a sealing ring installed on the outer wall of the operating part 50. Thus, the second limiting part 512 is detachable, which facilitates the installation of the first elastic member 52 on the outside of the operating part 50 and the installation of the operating part 50 in the installation channel 15.

[0079] Please see Figure 3Furthermore, the distance between the lower end face of the operating part 50 and the top surface of the water receiving box 70 is H2, where H2 ≥ 1mm. This ensures that the top surface of the water receiving box 70 will not interfere with the lower end of the operating part 50, guaranteeing that the operating part 50 will not affect the installation and removal of the water receiving box 70.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application.
