Description

Technical Field

[0001] The present invention relates to a bathtub. Background Art

[0002] With the progress of society, people's life rhythm is getting faster and their work is getting busier. To relieve the pressure in life or work, ordinary people will choose to soak in the bathtub to relax their body or mind.

[0003] In order to enable a person to sit or lie comfortably in the bathtub, the cavity of the bathtub needs to have enough space. Therefore, it takes a long time to fill the cavity with enough water. During the waiting process, a person has already taken off their clothes and sat in the bathtub, and it is very easy to catch a cold due to the influence of the external temperature difference. Therefore, during the waiting process, a bathtub shower can be used to prevent catching a cold. However, the shower head configured on the bathtub itself has only one fixed position. If taking a shower, a person needs to hold the shower head for a long time. In addition, the shower head can only shower a part of the body. If showering other parts of the body, such as the back, a person needs to hold the shower head to rinse. However, for the elderly, due to muscle aging, they may not be able to use it flexibly. Another solution is that before entering a full bathtub, an additional independent shower system can be used to take a shower to keep the body warm. However, it requires additional planning and installation, increasing the cost. Moreover, the external shower system sprays into the bathtub from the outside. The distance increases, and the spraying range is conical, not concentrated, and it will spray outside and directly flow into the sewer and be discharged, causing waste of water resources. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a bathtub with a shower function.

[0005] The technical solution adopted by the present invention to solve its technical problems is:

[0028] Refer to Figures 1 to 10 a bathtub, which includes a bathtub main body 1 and a waterway provided inside the main body. The bathtub main body 1 has a bathing cavity 2, the top of the cavity 2 is a bathtub opening 3, and a spray bar 4 is provided on the bathtub main body 1. The spray bar 4 includes a rod body 41 and a switch valve seat 42. The end of the rod body 41 is hinged on the bathtub main body 1 and a plurality of front nozzles 51 are arranged on the surface. A warm water channel 43 is provided inside it to connect the front nozzles 51. The warm water channel 43 is controlled by the switch valve seat 42 to communicate with the waterway so that warm water is sprayed towards the human body through the front nozzles 51. Without holding by hand, it warms the human body in the bathtub and prevents the human body from getting cold and catching a cold. Since spraying is carried out in the bathtub, the water will directly fall and flow back into the bathtub to add water synchronously with the bathtub faucet, without wasting water resources. The rotated-out spray bar 4 can also be used as a handrail. People in the bathtub can hold the spray bar 4 to stand up or sit down and prevent floating in the bathtub.

[0029] As a preferred solution of the present invention, a rear nozzle 52 for spraying towards the human body is provided on the end face of the bathtub opening 3. When the spray bar 4 rotates out, the rear nozzle 52 is arranged opposite to the front nozzle 5l to achieve an enclosed shower, and the warming effect is better. The rear nozzle 52 is independently controlled to communicate through a switch 8.

[0030] The above-mentioned front and rear nozzles both include a mounting base 53 and a spray nozzle 54. The mounting base 53 is connected and fixed to the rod body 41 or the bathtub opening 3. One end of the spray nozzle 54 is a mist outlet 55, which can convert the water sprayed out of the nozzle into mist-like water vapor to spray the human body with a shower. Since the sprayed mist water is light in weight, it will float around the human body to form a thermal insulation layer, which has a better warming effect; the other end is a ball head 56 movably connected to the mounting base 53. The spray nozzle 54 can be adjusted in multiple dimensions through the ball head, specifically, it can swing 15° in each direction, so that multiple nozzles can independently adjust the spray position on the human body, and form a three-dimensional spray when spraying, thereby expanding the coverage of the thermal insulation layer. The mist outlet 55 passes through the ball head 56 and is connected to the outside. In order to achieve a sealed and movable connection between the spray nozzle 54 and the mounting seat 53, a sealing ring 57 is provided at one end of the ball head 56. The spherical surface of the ball head 56 abuts against the sealing ring 57 to seal the mist outlet 55 and the warm water channel 43. A C-shaped retaining ring 58 is provided at the other end and is clamped between the ball head 56 and the outlet of the mounting seat 53 to perform reliable limit installation to prevent loosening. At the same time, the softness of the silicone enables flexible movement, which is more convenient for adjustment.

[0031] The bathtub body 1 is provided with hot and cold water circuits and a mixed water circuit. A temperature control handle 9 is provided on the bathtub body 1. The hot and cold water circuits merge into the temperature control handle 9. The temperature control handle 9 adjusts the proportion of warm water to be directed to the spray rod 4 and the rear nozzle 52. The temperature control handle 9 can simultaneously control the water outlet temperature of the front and rear nozzles, which is very convenient to use.

[0032] The spray rod 4 is connected to the bathtub opening 3 through the switch valve seat 42 and realizes circular swing with the switch valve seat 42 as the center. The switch valve seat 42 includes a rotating seat body 44, a switch valve body 7, a water inlet fixed seat 6 and a handle for operating the switch valve body 7. The water inlet fixed seat 6 is fixed on the bathtub body 1 and connected to the mixed water channel. A water inlet chamber 61 is provided in the water inlet fixed seat 6. The switch valve body 7 is sealed in the water inlet chamber 61 and closes the opening of the water inlet chamber 61. The water inlet 71 of the switch valve body 7 is connected to the water inlet channel 62 of the water inlet fixed seat 6. A water outlet 72 is provided on the side of the switch valve body 7 to connect to the water inlet chamber 61. The rotating seat body 44 includes a sleeve portion 45 and a water outlet portion 46 connected to the rod body 41. A water through hole 63 is provided on the side of the water inlet fixed seat 6 to connect to the water inlet chamber 61. The sleeve portion 45 is sleeved on the side of the water inlet fixed seat 6 and is sealed with sealing members on the upper and lower parts. The water through hole 63 is located between the two seals and is sealed and connected to the water outlet portion 46, and is connected to the warm water channel 43 of the rod body 41 through the water outlet portion 46.

[0033] Furthermore, the sidewall of the water inlet holder 6 is provided with an inner limiting groove 64, and the inner sidewall of the sleeve portion 45 is provided with a corresponding outer limiting groove 47. A C-shaped ring is mounted on the outer limiting groove 47 and snaps into the inner limiting groove 64, thereby axially positioning the water inlet holder 6 and the sleeve portion 45. This prevents displacement of the rotating seat 44, which could cause the seal between the water hole 63 and the water outlet 46 to fail. A threaded tube 65 is provided at the end of the water inlet holder 6. This threaded tube 65 passes through the wall of the bathtub body 1 and is secured by a locknut 66, connecting to the water path within the bathtub body 1. This threaded connection structure enables simple and reliable installation. A friction washer 48 is sandwiched between the rotating seat 44 and the water inlet holder 6. This friction washer 48 effectively prevents interference between the rotating seat 44 and the surface of the water inlet holder 6 during rotation, preventing uneven rotation or scratches on the surface of the water inlet holder 6.

[0034] To facilitate entry and bathing for the elderly and children, an opening 11 is provided in the side wall of the bathtub body 1. This lowers the height of entry, making it easier for the elderly and children to enter and exit the bathtub. A door 12 is provided in the opening 11. The shape of the door 12 matches that of the opening 11, facilitating its closing and sealing. A handle 13 is provided on the door 12. The handle 13 interacts with a bolt 14 disposed within the door 12, causing the bolt 14 to engage within the frame of the opening 11, thereby locking the door 12 and sealing the opening 11.
