As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
In an embodiment of the invention, a water dispenser is provided, which comprises a heating device and a splash-proof faucet 1.
According to the water dispenser in the embodiment, the anti-splash faucet 1 is arranged in the water dispenser, so that hot water flows out through the anti-splash faucet 1 after the water is heated by the heating device in the water dispenser, the hot water does not need to splash, and the purpose of preventing the hot water from splashing when the water dispenser releases hot water can be achieved. Meanwhile, the splash-proof faucet 1 is simple in structure, and components are not additionally arranged, so that the fault rate and the cost of the water dispenser are reduced.
Referring to fig. 1 to 4, a splash-proof faucet 1 according to an embodiment of the present invention includes: a housing 10 in which a water inlet pipe 20, a water flow passage 30, and an air flow passage 40 are formed independently of each other, the air flow passage 40 is disposed at one side of the water flow passage 30 and has an air flow inlet 410 and an air flow outlet 420, when hot water flows through the water flow passage 30, the air flow inlet 410 is capable of collecting hot vapor floating upward from the hot water and discharging the hot vapor out of the housing 10 through the air flow outlet 420, the water inlet pipe 20 is used for receiving the hot water and flowing into the water flow passage 30; the flow slowing device 50 is arranged between the water inlet pipe 20 and the water flow channel 30, water flows into the water flow channel 30 after flowing through the flow slowing device 50, and the contact area between hot water and the air flow inlet 410 can be increased.
According to the anti-splash faucet in the above embodiment, referring to fig. 3, since the water inlet pipe 20, the water flow channel 30 and the air flow channel 40 are formed in the housing 10 independently, when the hot water flows into the water flow channel 30, the air flow inlet 410 of the air flow channel 40 starts to collect the hot vapor drifting upward from the hot water and the hot vapor is discharged out of the housing 10 through the air flow outlet 420. The flow delaying device 50 is disposed between the water inlet pipe 20 and the water flow passage 30, and when hot water flows into the water flow passage 30 from the water inlet pipe 20, the contact area between the hot water and the air flow inlet increases after the hot water flows through the flow delaying device 50, and the contact time is prolonged. The increased contact area between the hot water and the airflow channel 40 is beneficial to the collection of the hot vapor by the airflow inlet 410, and the flow slowing device 50 also avoids the backflow caused by the excessive flow velocity of the water flow, so that the hot water flows out of the airflow channel. The water inlet pipe 20, the water flow channel 30 and the air flow channel 40 are all formed by the shell 10, and only certain changes are made to the structure of the cavity of the faucet, so that the use of some components is reduced. The embodiment of the invention can realize the aim of the splash-proof water faucet with simple structure and low failure rate.
In the embodiment of the present invention, the airflow inlet 410 is always located above the water flow channel 30, and the water flow cannot enter the airflow inlet 410 due to the gravity. The aperture of the gas stream inlet 410 is as large as possible to facilitate collection of the hot vapor.
Further, an airflow inlet 410 is formed at a position where water flow cannot reach at an upper end of an inner wall surface of the water flow passage 30, an airflow outlet 420 is formed in an outer wall surface of the casing 10, and water vapor enters the airflow inlet 410 upward and is discharged out of the casing 10 through the airflow outlet 420. Preferably, there may be more than one airflow inlet 410 and airflow inlet 410.
Further, the housing 10 forms a barrier between the water flow path 30 and the air flow path 40, and the water flow path 30 and the air flow path 40 communicate at the upper end of the barrier, which is always higher than the level of the water flow in the water flow path 30. The communication between the water flow channel 30 and the air flow channel 40 at the upper end of the barrier is such that the air flow inlet 410 is maximized to sufficiently collect the hot vapor in the hot water flow.
It should be noted that the barrier has a certain height. On one hand, the water flow can be prevented from splashing into the air flow channel 40 after impacting and blocking. On the other hand, when the water flows, there is enough space above the water in the water passage 30 to prevent the steam from accumulating in a short time and then generating a large pressure.
In some embodiments, the flow slowing device 50 comprises a flow slowing chamber 510, a water baffle 520 and a through hole 530, wherein the through hole 530 is formed at a lower end of the water baffle 520, the water flow entering the flow slowing chamber 510 hits the water baffle 520 and flows out of the through hole 530, a horizontal direction length of the through hole 530 is greater than a diameter of the water inlet pipe 20, and a cross-sectional area of the through hole 530 is greater than a cross-sectional area of the water inlet pipe 20.
In this embodiment, the flow slowing device 50 mainly plays two roles: firstly, the flow rate is reduced under the condition that the flow rate of the water in the water flow channel 20 is kept unchanged, and the reduction of the flow rate can prevent water splash from entering the air flow channel 40. Secondly, the contact area between the water flow in the water flow channel 30 and the air flow channel 40 can be increased, that is, the contact area between the water flow and the air is increased, which facilitates the separation of the water vapor from the water flow.
Specifically, when water flows into the buffer chamber 510 from the water flow channel 20, the cross section of the water flow perpendicular to the water flow increases, and the water flow fills the buffer chamber 510 after impacting the water baffle 520. The through holes 530 are generally formed at the lower end of the water guard 520, and the length of the through holes 530 in the horizontal direction is greater than the diameter of the water flow channel 20, so that the contact area of the water flow and the air in the horizontal direction is increased and the water flow becomes thinner at the time of water flowing into the water flow channel 30, which is advantageous for sufficient separation of steam and hot water. Meanwhile, the cross-sectional area of the through hole 530 is larger than that of the water outlet channel 20, so that the flow rate of the water flow can be reduced, and water drops are prevented from being stirred by the excessive water flow.
It should be noted that the slow flow device 50 may also be implemented by other specific structures. For example, the flow slowing device 50 may be formed by a plurality of flow blocking columns disposed in the water flow channel 20 and the water flow channel 30, and when the water flows through the flow blocking columns, the flow rate is reduced and the water flowing through the flow blocking columns becomes turbulent and disturbs each other, thereby increasing the contact area between the water and the air.
In certain embodiments, the upper opening of the water flow passage 30 is larger than the lower opening. The upper opening of the water flow passage 30 is larger than the lower opening thereof to form a half funnel shape. On one hand, the water flow channel 30 is substantially half funnel-shaped, so that a wide space is provided when the water flow enters the water flow channel 30, and the water flow is guided by the water flow channel 30 which is inclined downwards, thereby further preventing the water flow from splashing when the water flow enters the water flow channel 30. On the other hand, the contact area between the water flow and the air flow channel 40 at the upper end of the half funnel-shaped water flow channel 30 is increased, which is more favorable for the water vapor to enter the air flow channel 40.
In some specific embodiments, the buffer chamber 510, the water guard 520, and the through-hole 530 are formed by the housing 10. In this embodiment, the structure of the splash tap 1 is further simplified by forming the buffer chamber 510, the water guard 520, and the through hole 530 from the housing 10, and the splash tap 1 is formed by injection molding of plastic in one piece.
Specifically, the splash tap 1 is divided into two parts, which are respectively injection molded, and then the two parts are assembled, i.e., the splash tap 1 in this embodiment is formed. The two parts can be respectively injection-molded in an upper-lower structure or in a left-right structure.
In some specific embodiments, the water flow channel 30 includes a water flow outlet 310, and the air flow outlet 420 is disposed around the water flow outlet 310 of the water flow channel 30. In some cases, as the water vapor flows out of the flow passage 40, some of the hot vapor may pre-condense into droplets and flow out of the flow outlet 420. The user can receive water right, and the water vapor condensed beads can be prevented from causing the periphery to be percolated. It is also the case that a small portion of water entering the air flow passage 40 from the water flow passage 30 is just received in the cup when receiving water.
In some embodiments, an insulating sleeve 60 is also provided, and the insulating sleeve 60 is disposed around the gas flow outlet 410. The heat insulation sleeve 60 is arranged to prevent a water receiving person from accidentally touching the water receiving opening or prevent a cup placed at a water receiving money from accidentally touching the water receiving opening to cause scald. The outer wall of the airflow outlet 410 may be provided with external threads, and the heat insulation sleeve 60 is provided with internal threads matching with the external threads.
In this embodiment, the heat insulation sleeve 60 may also be clamped on the outer wall of the airflow outlet 410 or connected by magnetic attraction. The heat insulating sleeve 60 is made of a material with low thermal conductivity, such as rubber, ultra-fine glass wool, high silicon cotton, and the like.
In some embodiments, a valve 70 is further provided, and the valve 70 is provided in the water flow passage 20 for controlling the opening and closing of the water flow passage 20. The valve 70 may control the flow of water and may be a manual wrench valve.
In certain specific embodiments, the valve 70 is a solenoid valve. The electromagnetic valve can be controlled by one key, so that the electrification degree of a product is improved. The solenoid valve is generally disposed in the water flow passage 20, and is convenient for controlling the flow of water.
In some embodiments, the heating device of the water dispenser is an instant heater.
Generally speaking, there are two main types of heating for a water dispenser, one is to store hot water in an insulation box by heating, and the other is to heat a water flow passing through an instant heating type heater. The tankless heater, because it heats the water flow in a short time, cannot heat evenly, resulting in more water vapor. The splash-proof faucet can effectively prevent the phenomenon that hot water of a water heater with an instant heating heater splashes.
In all the above embodiments, the anti-splash faucet 1 is further provided with a screw hole 70, and the screw hole 70 is used for facilitating the fixing with the water dispenser.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
