Description of the invention: ~ [Technical field to which the invention pertains] - The present invention relates to a jacuzzi, and more particularly to a jacuzzi having a function of discharging back water. [Prior Art] - Referring to Fig. 1, a conventional jacuzzi 1 includes a cylinder block 11 and a plurality of return pipes 13 which are respectively assembled and circumferentially embedded in the peripheral wall of the cylinder block 11, the return pipe 13 is connected to a return water motor 12. The cylinder block 11 is provided with a plurality of nozzles 110 connected to the return pipe 13 facing the inner surface, and the water return motor 12 will drive the water flow in the return pipe 13 to make the water flow in the return pipe 13 and the cylinder. The body 11 circulates and the water is flushed out from the nozzle 110 to achieve the massage effect. When the use is completed, the water return motor 12 is stopped, and the water in the return pipe 13 is also stopped. The bottom of the cylinder block 11 is further provided with a water leakage hole (not shown) for discharging the water in the cylinder block 11 after use. At this time, the water located in the return pipe 13 cannot flow 0 Hi due to the loss of the power supplied from the water return motor 12, and is accumulated in the return pipe 13. If the residual water accumulated in the return pipe 13 is not discharged, it will not only smell bad, but also cause foreign matter such as moss or mold to grow in the return pipe 13, and when the user uses the jacuzzi 1 again, the return pipe 13 is not cleaned out. The water is easy to affect the health of the user. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a jacuzzi having a discharge backwater function that can discharge residual water from a return pipe. 5 1287443 Thus, the present invention has a jacuzzi that discharges water back, and includes a body, an air intake unit, and a water return unit. The peripheral wall of the cylinder body faces the inner surface, and the plurality of nozzles and the rolling unit comprise a vent pipe which is embedded around the peripheral wall of the cylinder and has an air inlet opening outside the cylinder body, and an adjustment provided at the air inlet switch. The return water unit includes a return pipe, a water return motor, and a water outlet pipe which are buried in the inner wall of the cylinder body and are sequentially connected. 6. The front end of the return pipe communicates with the inside of the cylinder, so that the water contained in the cylinder flows in, and the return water motor connected at the end thereof pushes the inflowing water to the outlet pipe. The outlet pipe is stacked side by side with the vent pipe and is commonly connected to the nozzles on the peripheral wall of the cylinder block. Therefore, under the operation of the return water motor, the water is sent from the return pipe to the water outlet pipe, which can drive the air into the gas pipe from the intake air π, so that the water and the air are flushed out together by the nozzle. The return pipe is adjacent to the return water motor at a low point of the pipeline, and here a drain branch pipe extending to the outside of the cylinder and a solenoid valve are provided. The drain branch has a downwardly open drain section, the solenoid valve being disposed in the drain section and being controllable to open the drain branch to allow water from the first, outlet water to drain. According to the invention, the drainage branch pipe and the electromagnetic valve installed in the return pipe can discharge the residual water in the pipe after the return water is stopped, so as to keep the jacuzzi clean and hygienic. [Embodiment] The detailed description of the preferred embodiments of the present invention will be apparent from the following description of the preferred embodiments. As shown in FIG. 2, it is a preferred embodiment of the jacuzzi 1284443 having a function of discharging and returning water. The jacuzzi 2 includes a cylinder 21 for holding water, an air intake unit 4, and a water return unit 3. , and a pneumatic switch 5. A plurality of heads 211 are provided on the inner wall surface of the cylinder block 21. The air intake unit 4 includes a vent pipe 41 and an adjustment switch 42. The vent tube 41 is embedded in the peripheral wall of the cylinder block 21 and has an air inlet 410 open to the upper surface of the cylinder block 21; the adjustment switch 42 is disposed at the air inlet 410 for adjusting air in and out The size of the opening. The return water early 3 includes a return water pipe 33, a water return motor 31, a water discharge official 32 that is circumferentially embedded in the peripheral wall of the cylinder block 21 and connected to the water discharge nozzles 211, and a water return pipe 33 is provided in the water return pipe 33. A drain branch 331 and a solenoid valve 332 at the return water motor 31 are adjacent. In this embodiment, the return pipe 33 is connected to the lower position of the return water motor 31, whereby the end section of the return pipe 33 forms a low point of the official road, and the drain branch 331 and the electromagnetic valve 332 are disposed in the pipeline. Low. The air pressure switch 5 is connected through an air tube 6 and is used to activate the water return motor 31. The head end of the return pipe 33 is open to the inner surface of the peripheral wall of the cylinder block 21, and is provided with a 'water-receiving member 333' to thereby filter the impurities in the water flowing into the pipe, and the return water motor 31 connected to the end of the pipe pushes the inflow. The water flows toward the outlet pipe 32, and the outlet pipe 32 is disposed side by side with the vent pipe 41, and is connected to the nozzles 211 on the peripheral wall of the cylinder block 21 in common. Therefore, under the operation of the water return motor 31, the water is sent from the return water pipe 33 to the water outlet pipe 32 via the return water motor 31, and the T-flow air enters the vent pipe 41 from the air inlet 410, so that the water and the air are together by the spray head 211. Rush out. In this embodiment, the drainage branch pipe 331 is a three-way pipe that is inserted into the return pipe 7 1287443 33, and one of the downward extensions is a drainage section 330, and can be connected with a drainage pipe that guides the ground drainage hole (not shown) Show) connection. The solenoid valve 332 is provided at the drain section 330. The solenoid valve 332 can be controlled to switch the drain branch 331 and open the drain branch 331 to allow water to drain from the tube.
在本實施例，該電磁閥332設有一獨立的排水開關（ 圖未示），在一般使用狀態，該電磁閥332封閉該排水支管 331 ;當使用者按下該排水開關，該電磁閥332開放該排水 支管’讓管中的水排出。本發明電磁閥332的設計不以此 為限，也可以是與迴水馬達31共同控制，當馬達31運轉 時，該電磁閥332通電並封閉該排水支管331，而在該馬達 31停止運轉的同時，該電磁閥332斷電並切換為開放該排 水支管331，讓管中的水排出。 歸納上述，藉由此一裝設在該迴水管33鄰接迴水馬達 31處的排水支管331 ,可將管中餘水排出，以保持該按摩 浴缸2之清潔衛生，確實可達到本發明之目的。 准以上所述者，僅為本發明之較佳實施例而已，當不 能以此限定本發明實施之範圍’即大凡依本發明申請專利 範圍及發明說明内容所作之簡單的等效變化與修飾，皆仍 屬本發明專利涵蓋之範圍内。 【圖式簡單說明】 圖1是一習知之按摩浴缸之透視立體圖；及 圖2疋纟發明之具有排放迴水功能之按摩浴缸的較 佳貫施例之透視立體圖。 8 1287443 【主要元件符號說明】 2· · · •按摩浴缸 332 · · •電磁閥 21 · · •缸體 333 · · •濾水件 211 · •喷頭 4 · · · •進氣單元 3 · · · •迴水單元 41· · · •通氣管 31 · · • 迴水馬達 410 · · •進氣口 32 · · •出水管 42· · · •調整開關 33 · · • 迴水管 5 · · · •氣壓開關 330 · •排水段 6 · · · •空氣管 331 · •排水支管In this embodiment, the solenoid valve 332 is provided with a separate drain switch (not shown).
