Description

Technical Field

[0001] The present invention relates to the technical field of sanitary ware devices, and particularly relates to a shower device capable of draining the stored water inside. Background Art

[0002] Common shower devices include shower faucets, shower heads, and shower main body kits, etc. After the valve is closed after use, water will remain in the internal cavity and pipeline of the shower device. When in use, the residual cold water inside will flow out first and spray on the user, causing discomfort. Moreover, the water remaining inside for a long time in the pipeline is prone to scale formation, bacteria growth, or corrosion and damage of internal parts. In areas with low temperatures, the accumulated water inside is likely to freeze and cause the pipeline to burst, etc.

[0003] To solve these problems, many peers have made some improvements to the existing shower devices. For example, the patent number is 202010869498.0, and the patent name is a shower faucet with a drainage function. A thermostatic valve core and a water distribution valve core are arranged in the faucet main body. A rotating seat, a fixed valve plate, and a moving valve plate are arranged in the water distribution valve core. At least three water outlet holes are opened on the fixed valve plate. The bathtub water outlet nozzle, the overhead shower assembly, and the handheld shower head assembly are respectively communicated with the corresponding water outlet holes. A communication groove is opened on the lower surface of the moving valve plate. When the shower faucet is closed, the communication groove is connected to the three water outlet holes corresponding to the bathtub water outlet nozzle, the overhead shower assembly, and the handheld shower head assembly. After the shower faucet is closed, the three water outlet holes corresponding to the bathtub water outlet nozzle, the overhead shower assembly, and the handheld shower head assembly are communicated with each other through the communication groove. At this time, the accumulated water in the pipelines corresponding to the shower head and the shower nozzle converges in the communication groove through their respective water outlet holes. The bathtub water outlet nozzle is lower than the shower head and the shower nozzle. The water in the communication groove is discharged outward through the bathtub water outlet nozzle, so that the accumulated water inside the faucet main body and in the pipelines corresponding to the overhead shower assembly and the handheld shower head assembly is discharged outward through the bathtub water outlet nozzle, realizing automatic drainage when the shower faucet is closed.

[0004] The above structure preferably solves the problem that the accumulated water in the shower kit cannot be discharged after the faucet is closed. However, this kind of faucet still uses a relatively traditional rotary-controlled water distribution valve core. When in use, only by rotating the water distribution valve core to different positions through the switching rod can water be supplied or drained to the overhead shower assembly and the handheld shower head assembly, which is inconvenient to operate. Users often rotate to the wrong position, resulting in chaotic water output from the overhead shower or the handheld shower head. Currently, shower main bodies with multiple button valve cores (commonly known as piano keys) have been widely popularized in the market. However, this kind of water distribution valve core in the above structure cannot be modified to be suitable for independent installation of piano keys into the button valve core type shower main body for drainage, and cannot meet the needs of consumers.

[0005] Moreover, this rotary water distribution valve core needs to simultaneously control the connection to the overhead shower, handheld showerhead, bathtub water outlet and drainage. There are too many water outlet holes on its fixed valve plate. This kind of water distribution valve core is usually made with side water inlet (at least three water inlet holes are provided on the side wall of the outer shell) and bottom water outlet mode, resulting in a complex structure of the water distribution valve core. It is easy to have problems with seal failure between the fixed valve plate and the moving valve plate. The sealed connection between the water distribution valve core and the shower main body is also difficult to handle. Poor sealing is likely to cause water to flow between different waterways.

[0006] In addition, in the above structure, the water inlet of the handheld showerhead assembly is arranged downward at the bottom of the faucet main body, and its interface position is lower than the bathtub water outlet nozzle. The accumulated water at the elbow of the connecting pipe of the handheld showerhead assembly cannot be discharged through the bathtub water outlet nozzle, and there will still be a lot of accumulated water in the pipeline of the handheld showerhead assembly. Summary of the Invention

[0007] In order to solve the above problems, the purpose of the present invention is to provide a shower device capable of emptying the internal stored water, with a simple and reliable structural design, suitable for matching with a push-button type shower main body, convenient to use and operate, and capable of effectively emptying the accumulated water in the internal pipeline of the shower device after closing the valve.

[0008] To achieve the above purpose, the present invention adopts the following technical solutions:

[0009] A shower device capable of emptying the internal stored water, comprising a shower main body, an overhead shower, a handheld shower, a temperature control valve and a control valve. The control valve is connected with a control button. There is a valve cavity for installing the control valve in the shower main body. The bottom surface of the shower main body is provided with a downwardly arranged discharge port. Each valve cavity bottom surface is provided with a water inlet hole, a central hole and a drain hole. The central hole is communicated with the water outlet interface on the shower main body. Each drain hole is independently communicated with a discharge port; the control valve is provided with a fixed valve plate, a moving valve plate and an operating rod. The fixed valve plate is provided with a transition hole one, a transition hole two and a transition hole three respectively corresponding to and connected with the water inlet hole, the central hole and the drain hole. The moving valve plate is provided with a communicating concave cavity. The operating rod is used to push the moving valve plate to slide reciprocally so that the communicating concave cavity therein or the transition hole one is communicated with the transition hole two for water supply, or the transition hole two is communicated with the transition hole three for drainage.

[0010] Further, a valve core seat, a mounting cylinder body and a lever seat are provided in the control valve. The valve core seat, the fixed valve plate and the lever seat are fixedly connected to the mounting cylinder body. The valve core seat is used to fix the fixed valve plate. A first core seat hole, a second core seat hole and a third core seat hole are provided in the valve core seat. The first core seat hole, the second core seat hole and the third core seat hole respectively communicate the water inlet hole, the central hole and the drain hole with a first transition hole, a second transition hole and a third transition hole correspondingly. The operating rod is hinged in the lever seat and is used to push the movable valve plate to reciprocate and fit against the fixed valve plate, so that the communicating cavity either communicates the first transition hole with the second transition hole or communicates the second transition hole with the third transition hole.

[0011] Further, a sliding plate is provided between the lever seat and the movable valve plate. The sliding plate is fixedly connected to the movable valve plate. A sliding hole is provided in the sliding plate. The end of the operating rod is movably sleeved in the sliding hole and is used to push the sliding plate to drive the movable valve plate to reciprocate radially relative to the lever seat.

[0012] Further, guide blocks for preventing the sliding plate from rotating relative to the axis are provided between the lever seat and the sliding plate.

[0013] Further, the fixed valve plate and the movable valve plate are processed from ceramic materials.

[0014] Further, at least two positioning holes are provided on the bottom surface of each valve cavity, and positioning posts corresponding to the positioning holes are provided on the valve core seat.

[0015] Further, a sealing ring is provided between the control valve and the bottom surface of the valve cavity.

[0016] Further, the water inlet hole, the central hole and the drain hole are arranged in sequence from top to bottom.

[0017] Further, a water collecting groove is provided on the inner side of the middle part of the water outlet panel in the top spray shower. The top spray water inlet pipe in the top spray shower extends from top to bottom to be close to the bottom surface of the middle groove of the water collecting groove and is used to form a siphon channel during drainage.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the shower body of the present invention, a plurality of push-button control valves are provided, and each control valve independently controls a water-using device, which is convenient for operation and not prone to errors. A plurality of upwardly extending water outlet interfaces are provided on the shower body to facilitate independent connection of the overhead shower and the hand-held shower. The control valve can connect the water inlet hole with the water-using device pipeline for water supply during water use, and connect the water-using device pipeline with the drain hole for drainage when the valve is closed. Each drain hole is independently communicated with a discharge port provided on the bottom surface of the shower body, and can effectively drain the accumulated water in the pipelines of the overhead shower and the hand-held shower inside the shower device after the valve is closed. Each device can drain water independently without water cross-flowing between them.

[0020] 2. In the control valve of the present invention, a fixed valve plate and a movable valve plate are ingeniously arranged. The movable valve plate is pushed by an operating rod to slide relative to the fixed valve plate, so that the communication concave cavity provided in the movable valve plate can either connect the transition hole 1 with the transition hole 2 during water use or connect the transition hole 2 with the transition hole 3 during water shut-off. The independent drainage operation of the overhead shower and the hand-held shower is convenient.

[0021] 3. The overall structure of the control valve of the present invention is reliable. The installation cylinder body, the lever seat, the valve core seat, the fixed valve plate, the movable valve plate, the sliding plate, the operating rod, etc. provided in the control valve are easy to process and assemble, which is convenient for stably and reliably ensuring the product quality. The control valve is reliably installed and connected in the shower body and has good sealing performance; the operating rod is convenient to be connected with a button for operation, and can well meet the market demand.

[0034] The following further elaborates on the present invention in detail in conjunction with the drawings and specific embodiments:

[0035] See Figure 1-9As shown in the figure, a shower device capable of draining the water stored inside includes a shower main body 1, an overhead shower head 2, and a hand-held shower head 3. A temperature control valve 4 and two or more control valves 5 are provided in the shower main body 1. The control valve 5 is connected with a control button. Each control valve 5 respectively controls the on-off of the water circuit connecting the overhead shower head 2 or the hand-held shower head 3. An upwardly extending water outlet interface 11 is provided on the shower main body 1. The water outlet interface 11 is respectively connected to the water inlet at the lower end of the overhead shower head 2 and the hand-held shower head 3. A valve cavity 12 for installing the control valve 5 is provided in the shower main body 1. A downwardly disposed discharge port 13 is provided on the bottom surface of the shower main body 1. An inlet hole 14, a central hole 15, and a drain hole 16 are provided on the bottom surface of each valve cavity 12. The inlet hole 14, the central hole 15, and the drain hole 16 are arranged in sequence from top to bottom, and the drain hole 16 is arranged at the lowermost side for convenient drainage. The inlet hole 14 is connected to the water supply channel inside the shower main body 1, the central hole 15 is communicated with the water outlet interface 11, and each drain hole 16 is independently communicated with a discharge port 13. A sealing ring 6 is provided between the control valve 5 and the bottom surface of the valve cavity 12 for hermetically connecting the bottom surface of the control valve 5 and the bottom surface of the valve cavity 12. The control valve 5 is used to dynamically connect the inlet hole 14 and the central hole 15 for water supply, or dynamically connect the central hole 15 and the drain hole 16 for drainage. When the control valve 5 is closed, the central hole 15 and the drain hole 16 are immediately communicated with each other. After being communicated, the water in the pipeline of the overhead shower head 2 or the hand-held shower head 3 flows through the central hole 15, through the internal channel of the control valve 5, and then discharges towards the drain hole 16, forming a siphon effect during the drainage process, which can smoothly drain the accumulated water in the pipeline of the overhead shower head 2 or the hand-held shower head 3. The internal pipeline channels of the shower main body 1, the overhead shower head 2, or the hand-held shower head 3, especially at the turning points, can be made into a structure without dead ends, which is convenient for smooth drainage without water accumulation.

[0036] The control valve 5 is an independent component that is convenient to install in the shower main body 1 and is convenient for independent control operation through control buttons. A valve core seat 51, a fixed valve plate 52, a movable valve plate 53, an operating rod 54, an installation cylinder 55 and a lever seat 56 are provided in the control valve 5. The valve core seat 51 is hermetically connected to the bottom surface of the valve cavity 12. The valve core seat 51, the fixed valve plate 52 and the lever seat 56 are fixedly connected to the installation cylinder 55. The operating rod 54 is hinged in the lever seat 56 and is used to push the movable valve plate 53 to reciprocate. The fixed valve plate 52 and the movable valve plate 53 are processed from ceramic materials or can be made of reinforced plastic materials. The surface friction coefficients of the two are small and wear-resistant, ensuring that they can be used for a long time. A core seat first hole 511, a core seat second hole 512 and a core seat third hole 513 corresponding to the water inlet hole 14, the central hole 15 and the drain hole 16 are respectively provided in the valve core seat 51. The fixed valve plate 52 is fixedly connected to the valve core seat 51, and a transition first hole 521, a transition second hole 522 and a transition third hole 523 corresponding to the core seat first hole 511, the core seat second hole 512 and the core seat third hole 513 are respectively provided therein. A communication cavity 531 is provided in the movable valve plate 53. The operating rod 54 is used to reciprocally push the movable valve plate 53 to fit against the fixed valve plate 52 for relative sliding, so that the communication cavity 531 either connects the transition first hole 521 and the transition second hole 522 to each other or connects the transition second hole 522 and the transition third hole 523 to each other. During the sliding switching process, the communication cavity 531 will not connect the transition second hole 522 to the transition first hole 521 and the transition third hole 523 at the same time. At least two positioning holes 17 are further provided on the bottom surface of each valve cavity 12, and positioning posts 514 corresponding to the positioning holes 17 are provided on the valve core seat 51.

[0037] In order to better install the movable valve plate 53, a sliding plate 57 is further provided between the lever seat 56 and the movable valve plate 53. The sliding plate 57 is fixedly connected to the movable valve plate 53. A sliding hole 571 (the sliding hole 571 can be designed in a long strip shape) is provided in the sliding plate 57. The end of the operating rod 54 is movably sleeved in the sliding hole 571. When the end on the outer side of the operating rod 54 is pressed, the end (inner end) sleeved in the sliding hole 571 is used to push the sliding plate 57 to drive the movable valve plate 53 to reciprocate radially relative to the lever seat 56. A guiding block 561 for preventing the sliding plate 57 from rotating relative to the axis is provided between the lever seat 56 and the sliding plate 57, ensuring that after the sliding plate 57 and the movable valve plate 53 are combined, they can just fit between the lever seat 56 and the fixed valve plate 52 for smooth sliding. A sealing ring can be added between the valve core seat 51 and the fixed valve plate 52 to ensure sealing.

[0038] On the basis of the foregoing structure, the operating rod 54 can also be set to a structure that pushes the movable valve plate 53 to swing eccentrically relative to the fixed valve plate 52 (the attached drawings are omitted). Another mechanism is used to realize the dynamic switching of the control valve 5, so that the communication cavity 531 in the movable valve plate 53 either dynamically connects the water inlet hole 14 with the central hole 15 for water supply, or dynamically connects the central hole 15 with the drain hole 16 for drainage.

[0039] On the basis of the foregoing structure, in order to better drain the accumulated water in the overhead shower 2, a water collecting groove 211 is provided on the inner side of the middle part of the water outlet panel 21 of the overhead shower 2. The overhead water inlet pipe 22 of the overhead shower 2 extends downward from top to bottom to be close to the bottom surface of the middle groove of the water collecting groove 211 for forming a siphon channel during drainage. The structure is shown in the attached Figure 10 drawing, which is convenient for forming a siphon effect during drainage and smoothly draining the accumulated water in the overhead shower 2.

[0040] When the present invention is in use, by pressing the control button connected to the control valve 5 (corresponding to different buttons for controlling the water outlet devices such as the overhead shower 2 or the hand-held shower 3), the operating rod 54 is pushed to slide the movable valve plate 53 upward, so that the communication cavity 531 connects the transition hole 521 with the transition hole 522. The water in the internal water supply channel of the shower body 1 sequentially passes through the water inlet hole 14, the core seat hole 511, the transition hole 521, the communication cavity 531, the transition hole 522, the core seat hole 512 and the central hole 15 and flows into the water outlet interface 11 and then supplies water to the overhead shower 2 or the hand-held shower 3 for use.

[0041] When turning off the water after use, press the control button to the other side to push the operating rod 54 to slide the movable valve plate 53 downward, so that the communication cavity 531 connects the transition hole 523 with the transition hole 522, and the water in the internal pipeline of the overhead shower 2 or the hand-held shower 3 sequentially passes through the water outlet interface 11, the central hole 15, the core seat hole 512, the transition hole 522, the communication cavity 531, the transition hole 523, the core seat hole 513 and the drain hole 16 and flows to the discharge port 13 for discharge.

[0042] The above are only the specific embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
