Description

Technical Field

[0001] This application relates to the field of kitchen and bathroom equipment technology, and in particular to a cup washer and a kitchen faucet. Background Technology

[0002] Currently, most kitchen cup washer units are installed at the faucet outlet for quick cleaning of cups and other utensils. However, existing cup washer units still have several shortcomings in terms of structural design and user experience: First, the tray assembly and the drain plate often lack a reasonable support structure, resulting in them fitting too tightly or having too small a gap. After washing, the water dripping from the cups cannot flow smoothly between them, easily leading to water accumulation, which may also breed bacteria over time. Second, the drain plates are mostly horizontally set or tilted in only one direction. During the washing process, debris washed out of the cups tends to accumulate around the drain plate, making it difficult to drain with the water flow. This requires frequent manual cleaning, increasing the burden of use. Third, the drain section of the drain plate is often a complete long strip structure. When draining, the water flow is easily concentrated due to surface tension, causing some water to splash onto the countertop, requiring additional wiping of the countertop and affecting ease of use. Furthermore, some cup washer valve core reset structures lack stability, easily leading to problems such as incomplete closure or awkward opening. Additionally, the water distribution between the cup washer and the faucet often experiences switching issues, meaning water may still flow from the faucet while the washer is in use, or the washer may supply insufficient water, failing to meet efficient cleaning needs. Moreover, the rubber pads and support frames of some cup washers are often fixedly connected, making it difficult to disassemble and clean the pads when they become dirty, resulting in poor cleaning convenience. All these problems indicate that the user experience and practicality of existing cup washers need further improvement. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by providing a cup washer and a kitchen faucet.

[0004] The technical solution of this application is implemented as follows: In a first aspect, this application provides a cup washer, the cup washer comprising: The valve seat is fixedly connected to the outlet end of the outlet pipe; The valve core has its lower end movable inside the valve seat and is equipped with an elastic reset member that moves the valve core upward. The upper end of the valve core extends out of the valve seat. The nozzle is installed at the upper end of the valve core; A flow guide plate, which has a connecting part, a flow guide part and a flow guide port. The connecting part is installed on the outside of the nozzle and has a connecting boss on the outside of the connecting part. The connecting boss is fitted onto the top of the valve core. The tray assembly is installed on the outside of the connecting part, and the tray assembly abuts against the upper end of the connecting boss, so that there is a gap between the tray assembly and the guide plate. When the tray assembly moves up and down, the guide plate, nozzle and valve core move up and down together, and the valve core switches between closed and open states by moving up and down.

[0005] The advantages or beneficial effects of the above technical solutions include at least the following: Secondly, this application also provides a kitchen faucet, which further includes: The faucet body is equipped with a water outlet pipe for supplying water to the cup washer; Mixing pipes are used to transport mixed hot and cold water; A cup-washing water pipe is used to supply water to the outlet pipe; The main water pipe supplies water to the kitchen faucets; An automatic water distributor is installed inside the kitchen faucet. The automatic water distributor includes a main inlet, a main outlet, and branch ports. The mixing pipe is connected to the main water inlet, the main water pipe is connected to the main water outlet, and the cup washing water pipe is connected to the branch port.

[0006] The advantages or beneficial effects of the above technical solutions include at least the following: 1. By setting a connecting boss on the outside of the guide plate connection, the support plate assembly is raised using the connecting boss, creating a reasonable gap between the support plate assembly and the guide plate. Water dripping from the cup after cleaning can flow smoothly between the support plate assembly and the bottom surface of the guide plate, avoiding water accumulation and bacterial growth, further ensuring hygiene during use. 2. The guide plate adopts a double-tilted design. On one hand, the overall relative horizontal surface tilts downwards towards the guide port; on the other hand, the inner bottom surface tilts downwards along the perimeter of the connection part towards the perimeter of the guide plate. This design not only guides the water flow to quickly converge and discharge through the guide port, but also carries the debris flushed out of the cup with the water flow to the perimeter of the guide plate, thereby automatically rinsing the area around the guide plate and thoroughly flushing away accumulated debris. This eliminates the need for frequent manual cleaning and significantly reduces the maintenance burden after use. 3. The notches on both sides of the flow guide precisely disrupt the surface tension of the water flow and the drainage tension of the flow guide. During drainage, the water flow does not form a concentrated jet, effectively preventing water from splashing onto the countertop, reducing subsequent countertop wiping work, and making the process more convenient and worry-free. 4. The valve core adopts a hollow structure and is equipped with a compression spring as an elastic reset component. One end of the compression spring abuts against the bottom wall of the valve seat, and the other end abuts against the bottom of the valve core. This structure ensures that the valve core stably closes the cup washer when moving upward and reliably opens when moving downward, with smooth switching between on and off states, avoiding problems such as incomplete closure or difficult opening. At the same time, the nozzle can be installed separately from the valve core or integrally molded, which can adapt to different usage needs and make the structural design more flexible. 5. In the tray assembly, the bottom of the rubber pad is provided with a protrusion that matches the mounting hole of the support frame. The rubber pad is detachably connected by the cooperation of the protrusion and the mounting hole. The rubber pad can be easily removed for cleaning when it is dirty, which further improves the convenience of cleaning. The automatic water distributor in the kitchen faucet can give priority to supplying water to the faucet body when it is turned on. When the cup washer is used and the valve core is opened, the water pressure change at the branch port will drive the piston to move, close the main water outlet and supply water only to the cup washer. This realizes a smooth switch between the faucet body and the cup washer, avoids water supply conflict between the two, ensures sufficient water supply to the cup washer and does not waste water flow to the faucet body. 6. High overall practicality and wide applicability: The cup washer has a compact overall structure, and the fixing methods of the valve seat and water outlet pipe (threaded fixing, snap fixing, etc.) can be adapted to different installation scenarios, making installation convenient; the components work together in a coordinated manner, have a long service life, and can fully meet the kitchen's needs for efficient, convenient and hygienic cup washing, significantly improving overall practicality and user experience.

[0014] Reference Figure 2 and Figure 3 A cup washer, wherein the cup washer 10 is installed at the outlet end of the water outlet pipe 26, and the cup washer 10 includes: Valve seat 11 is fixedly connected to the outlet end of water outlet pipe 26. Specifically, it can be fixed by thread, snap-fit ​​or other methods. The lower end of the valve core 12 is movably disposed inside the valve seat 11 and is equipped with an elastic reset member that allows the valve core 12 to move upward. The upper end of the valve core 12 extends out of the valve seat 11. Figure 6 As shown; when the valve core 12 moves upward, the water inlet of the valve core 12 is blocked, and the cup washer 10 is in the closed state; when the valve core 12 moves downward, the water inlet of the valve core 12 is opened, and the cup washer 10 is in the open state. In the open state, water flows out from the upper end of the valve core 12 to clean the cup. The valve core 12 has a hollow structure with holes near the bottom. Water can enter the valve core 12 through these holes and spray out from the top of the valve core 12, and... Figure 6 As shown in the upper part, when the valve core 12 moves upward, the hole of the valve core 12 is blocked by the inner wall of the valve seat 11, and the water flow cannot enter the valve core 12 through the hole. When the valve core 12 moves downward, the hole opens, and the water flow can enter the valve core 12 through the hole and spray out from the top of the valve core 12.

[0015] The cup washer 10 further includes: The nozzle 13 is installed on the upper end of the valve core 12, and the water flow sprayed from the valve core 12 is sprayed out through the nozzle 13; as another embodiment, the nozzle 13 can also be configured to be integrally formed with the valve core 12. Guide plate 14, such as Figure 2 As shown, the flow guide plate 14 is provided with a connecting part 141, a flow guide part 142, and a flow guide port 143. The connecting part 141 is installed on the outside of the nozzle 13, and a connecting boss 1411 is provided on the outside of the connecting part 141. The connecting boss 1411 is sleeved on the valve core 12, and the valve core 12 is located in the middle of the connecting boss 1411 and can pass through the connecting boss 1411. After the water sprayed from the nozzle 13 washes the cup, the water flows from the inverted cup into the flow guide plate 14 and drains through the flow guide port 143 and the flow guide part 142. Furthermore, such as Figure 8 As shown, the guide plate 14 is inclined downwards relative to the horizontal plane towards the guide port 143, and the axial direction of the connecting boss 1411 is perpendicular to the horizontal plane to ensure that the water can flow towards the guide port 143, which helps with drainage. Figure 8 As shown, the inner bottom surface of the guide plate 14 is inclined downwards along the periphery of the connecting portion 141 towards the periphery of the guide plate 14, as... Figure 7 and Figure 8 As shown, Figure 7 In the middle, the blue dotted arrows indicate the direction of water flow. There may be some debris in the cup. The debris will be washed to the guide plate 14. Due to the inclined setting, the water will flow to the periphery of the guide plate 14, cleaning the surrounding area of ​​the guide plate 14 and rinsing away the debris accumulated around it to avoid debris accumulation.

[0016] The cup washer 10 also includes a tray assembly 15, which is installed on the outside of the connecting part 141, and the tray assembly 15 abuts against the upper end of the connecting boss 1411, so that there is a gap between the tray assembly 15 and the guide plate 14, which is conducive to the flow of water from the tray assembly 15 and the inner bottom surface of the guide plate 14, and facilitates drainage. When the tray assembly 15 moves up and down, the guide plate 14, the nozzle 13, and the valve core 12 move up and down together, and the valve core 12 switches between a closed state and an open state by moving up and down. The guide section 142 extends downstream of the guide port 143, and the portions of the guide section 142 on both sides of the guide port 143 have notches 144. The notches 144 can disrupt the surface tension of the water flow, and the drainage tension of the guide section 142 prevents the drainage from splashing onto the countertop.

[0017] The cup washer 10 further includes: an external threaded section provided above the connecting boss 1411 for the connecting part 1411, and a support plate assembly 15 fixedly installed on the external threaded section.

[0018] Based on a further improvement to the above structure, the elastic reset element includes a compression spring 16, which is installed inside the valve seat 11. One end of the compression spring 16 abuts against the bottom wall of the valve seat 11, and the other end abuts against the bottom of the valve core 12. The compression spring 16 pushes the valve core 12 upward so that the cup washer 10 can remain in the closed state. Figure 6 As shown.

[0019] The pallet assembly 15 includes a support frame 151 and a rubber pad 152. The support frame 151 is installed on the outside of the connecting part 141, and the support frame 151 has a plurality of mounting holes 1511; the bottom of the rubber pad 152 has a plurality of protrusions 1521 that are adapted to the mounting holes 1511, and the protrusions 1521 are disposed in the mounting holes 1511 as follows. Figure 4 As shown, this allows users to more easily remove the rubber pad 152 from the support frame 151 for cleaning.

[0020] When using the cup, place it upside down on the rubber pad 152, ensuring that the nozzle 13 is at the mouth of the cup. Press the cup down, and the entire tray assembly 15 will move the guide plate 14 and the valve core 12 downward together, overcoming the thrust of the compression spring 16. The valve core 12 moves downward, and the water flows into the valve seat 11 through the opening at the bottom of the valve seat 11. The water can also enter the valve core 12 through the hole and be sprayed into the cup from the top of the valve core 12 through the nozzle 13 for cleaning. After cleaning, the user releases the cup. At this time, the compression spring 16 extends and pushes the valve core 12 upward, and the valve core 12 closes, completing the cleaning process.

[0021] like Figure 1 As shown, an embodiment of the present invention also provides a kitchen faucet, including a faucet body 21, on one side of which a cup washer 10 with the structure described above is installed.

[0022] The faucet body 21 contains a mixing valve core, which acts as the switch for the faucet body 21. Turning on the faucet body 21 activates the mixing valve core, which is used to mix hot and cold water. The faucet body 21 also includes: An automatic water distributor 25 is installed inside the faucet body 21. The automatic water distributor 25 includes a main inlet 251, a main outlet 252, and a branch port 253. The cross-section of the upper plug of the piston is larger than that of the lower plug. When the piston moves upward, the lower plug closes the main outlet 252 and opens the branch port 253. When the piston moves downward, the lower plug opens the main outlet 252 and closes the branch port 253. Mixing pipe 22, one end of which is connected to the outlet end of the mixing valve core, and the other end is connected to the main inlet 251; The main water pipe 24 has one end connected to the main water outlet 252 and the other end connected to the water outlet 210 of the faucet body 21. The cup washing water pipe 23 is used to supply water to the outlet water pipe 26; one end of the cup washing water pipe 23 is connected to the branch port 253, and the other end is connected to the outlet water pipe 26. When the mixing valve core is open and valve core 12 is closed (i.e., the tray assembly is not pressed down), the mixing valve core directs water flow from the main inlet 251 into the automatic distributor 25 through the mixing pipe 22, and then out through the main outlet 252, so that water can flow from the outlet head 210; specifically, as shown... Figure 10As shown on the right half, when the faucet body 21 is turned on, water first enters from the main inlet 251 and exits from the main outlet 252, supplying water to the faucet body 21's outlet 210. It should be noted that some water also enters the branch port 253 at this time. However, since the cup washer 10 is not in use, after the cup washer pipe 23 is filled, the water pressure in the branch port 253 is balanced, and the water flow tends to flow towards the main outlet 252, thus pushing downwards the piston in the middle of the automatic water distributor 25, which can move up and down. Figure 10 The right side shows the water supply for the faucet body 21. When the mixing valve core is open and valve core 12 is open (i.e., the tray assembly is pressed down), the mixing valve core directs water flow from the main inlet 251 into the automatic water distributor 25 through the mixing pipe 22, and then water exits from the branch port 253, causing water to flow from the nozzle 13 of the cup washer 10; specifically, as shown... Figure 10 As shown on the left, when the faucet body 21 is turned on and the user uses the cup washer 10, the valve core 12 is turned on, and water can flow through the branch port 253. The water pressure in the branch port 253 decreases, and the water flow can flow towards the branch port 253, thereby impacting the piston upward. Since the cross-section of the upper end of the piston is larger than the cross-section of the lower end of the piston, the water flow will push the piston upward. The lower end of the piston closes the main outlet 252, and the water flow cannot flow out from the main outlet 252, but can only flow out from the branch port 253 to supply water to the cup washer 10. It should be noted that the above-mentioned automatic water distributor 25 is a mature prior art. The content disclosed regarding the automatic water distributor 25 is only one of the many embodiments applicable to the automatic water distributor 25 of this application, and does not mean that only the above-mentioned automatic water distributor 25 can be used.
