Description

Buffer box for a heating device

The technology to which the present invention pertains provides a water collecting buffer box, and more particularly to a water collecting buffer box for a heating device for drinking water.

Hot water that is ready to use is a must for modern life. The conventional hot water heating device 20' is connected to a water inlet pipe 30' and a water outlet pipe 40', respectively, as shown in FIG. The water inlet line 30' is connected to the water source, and the water outlet line 40' is connected to a faucet 50'. When the user turns on the hot water switch of the faucet 50', the water enters the heating device 20' via the water inlet pipe 30', and is heated into hot water by the heating device 20', and then flows out from the water outlet pipe 40' for supply. User use.

However, the conventional heating device 20' has many drawbacks. For example, when the water in the heating device 20' is heated to hot water, the water volume expands due to the principle of thermal expansion and contraction, so that the thermally expanded water overflows the heating device 20'. Furthermore, the water vapor generated during the heating process often flows along the water outlet pipe 40' to the water outlet of the faucet 50', and is further cooled to form water droplets at the faucet 50', which not only destroys the beauty of the home, but also makes it easier. Dirty environment and increased user confusion.

In view of this, some manufacturers have proposed improved heating equipment, such as the Republic of China Open Patent No. 201207328. The water inlet pipe of the heating device is provided with an energy-saving device. When the water outlet unit of the heating device is turned on, the cold water in the water inlet pipe will quickly pass through the flow channel in the energy-saving device, and at this time, part of the cold water will flow into the cooling device. In the trough, at the same time, a puff The air in the groove of the bulging film will be sucked out to form a vacuum, and then the expansion film will shrink and deform in the direction of a cooling floor. Then, when the water outlet unit is closed, the expansion film will be restored to its original state and sucked into a part of the heating device. The hot water creates a negative pressure in the heating device, which prevents dripping of the water outlet unit and achieves energy saving.

However, the previously disclosed patent mainly controls the output and inflow of water in the energy-saving device through the shrinkage expansion of the expansion membrane. However, after long-term use, the expansion membrane often suffers from elastic fatigue due to the high heat environment, thereby reducing its efficiency and service life. Moreover, since the installation position of the energy-saving device relative to the heating device is not good, it often happens that the water contained in the expansion film has not been completely taken away, and new water enters, which also reduces the energy-saving effect.

The inventors have proposed a water collecting buffer box for a heating device in view of the above-mentioned deficiencies of the prior art, which effectively overcomes the defects of the prior art and can effectively release generated steam and hot expanded water when the heating device performs a heating action. And when the water is moving, the stored hot water is discharged together to achieve the effect of energy saving.

For the above purposes, the water collecting buffer box of the present invention is disposed on a heating device having a water storage tank, and the water storage tanks are respectively connected to a water inlet pipe and a water outlet pipe. The buffer box of the present invention comprises a communicating tube, a water collecting space and a floating element. One of the first ends of the communication tube is in communication with the water inlet conduit, and the second end is in communication with the water collection space. The water collecting space has an overflow opening to communicate with the external environment. The floating element is disposed in the water collecting space and adjacent to the second end of the connecting tube.

Therefore, when the heating device heats the water in the water storage tank, the water expanded by the heating and/or the generated steam passes through the water inlet pipe and the communication pipe, and pushes the floating element away from the second end of the communication pipe to enter the set. In the water space; conversely, when the water inlet pipe enters the water, the water in the water collecting space flows into the water inlet pipe through the connecting pipe due to the pressure difference, and the floating element closes the communicating pipe due to the liquid level in the water collecting space is lowered. At the second end, the communication between the connecting pipe and the water collecting space is closed.

According to another preferred aspect of the present invention, the water collecting space is provided with a limiting portion near the second end of the connecting tube, thereby restricting the floating element from floating in a certain space.

According to another preferred aspect of the invention, the floating element is a float.

According to another preferred aspect of the present invention, when the amount of water in the water collecting space exceeds a predetermined value, excess water can flow out through the overflow port.

According to another preferred aspect of the present invention, the overflow port is connected to an external through hole via a pipe, so that steam and excess water in the water collecting space can flow out through the through hole through the pipe.

According to another preferred aspect of the invention, the second end of the communication tube is not lower than the full water level in the water storage tank.

The invention further provides a heating system comprising a heating device and a buffer box, the heating device having a water storage tank connected to a water inlet pipe and a water outlet pipe. The buffer box includes a connecting tube, a water collecting space, and a floating element. One of the first ends of the communication tube is in communication with the water inlet conduit, and the second end is in communication with the water collection space. The water collecting space has an overflow opening to communicate with the external environment. The floating element is disposed in the water collecting space and adjacent to the second end of the connecting tube. Therefore, when the heating device heats the water in the water storage tank, the water expanded by the heating and/or the generated steam passes through the water inlet pipe and the communication pipe, and pushes the floating element away from the second end of the communication pipe to enter the set. In the water space; conversely, when the water inlet pipe enters the water, the water in the water collecting space flows into the water inlet pipe through the connecting pipe due to the pressure difference, and the floating element closes the communicating pipe due to the liquid level in the water collecting space is lowered. At the second end, the communication between the connecting pipe and the water collecting space is closed.

According to another preferred aspect of the present invention, the water collecting space is provided with a limiting portion near the second end of the connecting tube, thereby restricting the floating element from floating in a certain space.

According to another preferred aspect of the invention, the floating element is a float.

According to another preferred aspect of the present invention, when the amount of water in the water collecting space exceeds a predetermined value, excess water can flow out through the overflow port.

The following examples further illustrate the invention. They are intended to illustrate the invention and to illustrate various advantages of the specific embodiments of the invention, but are not intended to

Referring to Figures 2 to 4, the heating system 1 of the present invention mainly comprises a heating device 20 and a buffer box 10, and the buffer box 10 is applied to a heating device 20, which has a water storage device. The tank 22 is in communication with a water inlet line 30 at the bottom such that fluid (typically water) can enter the water storage tank 22 via the water inlet line 30 for heating. The heating device 20 is simultaneously connected to a water outlet conduit 40 at the top, and the outlet conduit 40 can be connected to a faucet 50 so that the user can turn on the faucet 50 to heat the hot fluid stored in the water storage tank 22 of the heating device 20 (usually It is hot water) and can be sent to the faucet 50 via the water outlet line 40.

The buffer box 10 of the present invention is disposed on the heating device 20 in a preferred embodiment, and the buffer box 10 is formed with a notch 11 on one side, and the water supply and delivery line 40 can pass through the notch 11 (ie, does not enter the buffer box). The port is connected to the water storage tank 22 of the heating device 20. A water collecting space 12 is defined in the buffer box 10, and the water collecting space 12 is opened at a top portion to form an overflow opening 13 through which the water collecting space 12 is electrically connected to the external environment, thereby maintaining the set. The chamber pressure state of the water space 12, the water collecting space 12 is opened at the bottom to form a flow port 14, and the flow port 14 is connected to a communication pipe 15, the communication pipe 15 has a first end 151 and a first The second end 152 has a first end 151 communicating with the water inlet pipe 30, and a second end 152 communicating with the flow port 14 of the water collecting space 12, thereby allowing the water collecting space in the buffer box 10 to pass through the communicating pipe 15. 12 is in fluid communication with the water inlet conduit 30.

The water collecting space 12 has a floating element 16 at the flow opening 14 which is slightly larger than the second end 152 of the connecting pipe 15. In the present embodiment, the floating element 16 is a floating ball, but the invention is not limited to a floating ball, and any conventional element having a floating function can be used as the floating element 16 of the present invention. When there is no water in the water collecting space 12, the floating member 16 is seated at the flow port 14 and closes the second end 152 of the communicating pipe 15 to close the communication between the communicating pipe 15 and the water collecting space 12.

As shown in FIG. 3A, when the heating device 20 heats the water in the water storage tank 22, the heated water expands and the water vapor is generated due to the principle of thermal expansion and contraction. Since the water storage tank 22, the water inlet pipe 30 and the communication pipe 15 are in fluid communication relationship, based on the communication pipe principle, the expanded water and steam enter the communication pipe 15 via the water inlet pipe 30, and push the floating element 16 out of communication. The second end 152 of the tube 15 (even if the floating element 16 floats), thereby returning the communication tube 15 with The communication relationship of the water collecting space 12. At this time, the expanded water and steam can enter the water collecting space 12 via the communication pipe 15, and the floating member 16 floats on the liquid surface in the water collecting space 12.

At this time, if the amount of water flowing into the water collecting space 12 exceeds the capacity of the water collecting space 12, excess water can flow out from the overflow port 13. In addition, in order to prevent the water flowing out from the overflow port 13 from remaining in the vicinity of the buffer box 10 and the heating device 20, a through hole 52 may be further formed in the faucet 50, and the overflow port 13 and the through hole 52 are connected by the pipeline. The water and steam flowing out of the overflow port 13 can be discharged through the through hole 52 of the faucet 50.

When the user turns on the hot water switch 54 of the faucet 50 to take hot water, the fluid in the water inlet pipe 30 enters the water storage tank 22 of the heating device 20 and moves in the direction of the conventional water outlet pipe 40, and the heat in the water storage tank 22 The water is pushed by the fluid entering from the water inlet pipe 30, i.e., flows to the water outlet pipe 40, and finally flows out through the faucet 50.

As shown in FIG. 3B, based on the Bernoulli's Principle, the water flowing in the water inlet pipe 30 generates a negative pressure with respect to the water collecting space 12, so that the water stored in the water collecting space 12 passes through the flow port 14 It flows into the communication pipe 15, enters the water inlet pipe 30, is taken away, and finally flows out through the water storage tank 22 and the water discharge pipe 40. When the water in the water collecting space 12 is flowing, the floating element 16 falls back to the flow port 14 and recloses the second end 152 of the communicating pipe 15 to close the fluid between the water collecting space 12 and the communicating pipe 15. It is connected to avoid air from entering the water inlet pipe 30 to generate air bubbles.

In addition, the buffer box 10 of the present invention can be provided with a limiting portion 17 in the vicinity of the flow opening 14 in the water collecting space 12, so that when the floating member 16 is floated, it can only be in the space defined by the limiting portion 17. Floating, so as to avoid drifting too far to the floating element 16 and failing to fall back smoothly to the flow port 14.

Furthermore, in order to allow the water in the water collecting space 12 to be taken away when the user picks up the hot water, the second end 152 of the connecting pipe 15 can be set at a height not lower than the full water level in the water storage tank 22. . By avoiding the principle of the connected pipe, a part of the residual water remains in the water collecting space 12, thereby affecting the function of the water collecting buffer of the present invention.
