Description

Technical Field

[0001] The present invention belongs to the technical field of water purifiers, and in particular relates to a water purifier capable of providing hot water. Background Art

[0002] Current water purifiers generally feature a heating function. Filtered pure water can be delivered at room temperature or heated. This requires a hot water pipe to deliver heated water to the user. However, heated water inevitably contains bubbles, which can cause the hot water to flow unsteadily from the spout, resulting in fan-shaped or scattered water. This can negatively impact the user's appearance and pose a risk of burns.

[0003] To solve this problem, existing technologies often install a water vapor separation box in the hot water pipeline to allow the gas in the hot water to escape and not affect the water flow pattern. The applicant has previously applied for several patents in this area. For example, CN210204462U discloses a water vapor separation box for an instant hot water dispenser, comprising a box body having a cavity structure, a water inlet on one side of the box body, and a water outlet at the lower end of the box body; the bottom surface of the box body has an inverted cone structure, and the water outlet is located at the lowest point of the inverted cone structure; the box body also has an exhaust channel surrounded by a baffle, and the exhaust channel is a columnar structure with an air inlet at the top and an exhaust at the bottom; the air inlet at the top of the exhaust channel is higher than the water inlet. An exhaust channel is set in the water vapor separation box. The exhaust channel is in the form of a full circle, and the incoming hot water and water vapor are separated; the air inlet at the top of the exhaust channel is higher than the water inlet to prevent hot water from directly entering the exhaust channel, and the exhaust pipe can block the impact of incoming water, so that water falls from directly above the water outlet, reducing the water flow path, while water vapor enters the exhaust channel and is discharged from the exhaust port below.

[0004] Another example is CN210582215U, which discloses a jet-type water vapor separation box. The box body is a hollow structure with a cold water inlet and a hot water inlet on one side and a water outlet at the lower end. The bottom surface of the box body is an inverted cone structure, with the water outlet located at the lowest point of the inverted cone structure. The box body is also provided with an exhaust channel, the bottom end of which is an exhaust port. The hot water inlet is tilted downward, with its lowest end connected to the interior of the box body. The inclination angle of the hot water inlet is 8 to 15 degrees, which is the angle between the hot water inlet and the horizontal line. In this structure, the hot water inlet is tilted downward, and the bottom of the box body is an inverted cone structure. This allows gravity to accelerate the rapid fall of excess water in the box, thereby reducing dripping.

[0005] CN216602490U also discloses a water vapor separation box, comprising a box body with a water inlet on one side and a water vapor outlet on the other. The water inlet and the water vapor outlet are connected by a slope, and the water vapor outlet is located at the lowest point of the water vapor separation box. A heating device is located adjacent to the water inlet, and the box body and the heating device are integrally connected. A V-shaped barrier layer is located within the box body, with the endpoints of the V-shaped barrier layer overlapping the center of the circle of the water vapor outlet, and two wings extending backward to intersect with the side walls of the box body. The tip of the V-shaped barrier layer is hollowed out, and its endpoints are aligned with the center of the circle, forming a circular water outlet with a radius smaller than the water vapor outlet. The portion of the water vapor outlet that does not intersect with the V-shaped barrier layer and the water outlet forms a fan-shaped steam exhaust port. This water vapor separation box can fully separate water vapor while ensuring that water flows straight and smoothly at different flow rates, preventing splashing and reducing safety hazards.

[0006] The principles of the aforementioned literature and other existing technologies on the market all rely on allowing the hot water to remain for a certain period of time during its dispensing process, using the specific shape of the steam separation box to allow the gas in the hot water to escape. However, the existing technology suffers from a reduction in the flow rate of the hot water after passing through the steam separation box, as well as the complex structure of the steam separation box and its high manufacturing cost. Summary of the Invention

[0007] The object of the present invention is to provide a water purifier which can provide hot water without using a water vapor separation box.

[0008] The technical solution adopted by the present invention is as follows: a water purifier that can provide hot water, including a hot water pipe with a heating device on the outside of the hot water pipe, and the hot water pipe provides hot water to the user through a water outlet; the characteristic is that at least one section of honeycomb tube is provided in the hot water pipe, which is installed in the hot water pipe by means of a fixing ring that is interference fit with the wall of the hot water pipe; the honeycomb tube body is in the shape of a circular tube, and a plurality of through holes are opened on the tube wall of the honeycomb tube.

[0009] The fixing ring is arranged at one axial end of the honeycomb tube, the center of the fixing ring is provided with a through hole smaller than the diameter of the honeycomb tube, and the edge of the fixing ring that matches the wall of the hot water pipe is provided with several notches.

[0010] The plurality of notches are centrally arranged within a sector range of less than 180° on the edge of the fixing ring.

[0011] Furthermore, the hot water pipe has multiple sections of honeycomb tubes, and the honeycomb tubes are fixedly connected by connecting pieces.

[0012] The connecting piece is provided with a plurality of through holes.

[0013] The diameter of the through hole of the honeycomb tube or the honeycomb tube located most downstream in the water flow direction among the honeycomb tube sections gradually decreases along the water flow direction.

[0014] The present invention can also adopt the following technical solution: the water outlet has a vertical through hole, through which the vertical section of the hot water pipe is passed; the upper part of the water outlet has a protruding upper limit end, the vertical projection of which overlaps with the hot water pipe; the lower part of the water outlet has a lower limit platform, the vertical projection of which also overlaps with the hot water pipe.

[0015] After extensive research, the applicant discovered that gases dissolved in pure water exist as microbubbles. Upon heating, these bubbles aggregate to form larger bubbles. This process doesn't occur suddenly, but rather occurs as microbubbles first aggregate into smaller bubbles, which then further aggregate into larger bubbles. It's the presence of these larger bubbles that affects the morphology of the water output, causing the problems described in the background technology section. Smaller bubbles, on the other hand, don't actually affect the flow pattern. Roughly speaking, a particle size of 0.5 mm can be considered the dividing line; only bubbles larger than 0.5 mm affect the flow pattern.

[0016] The honeycomb tubes in this invention form a grid within the waterway. When water containing bubbles flows through the tubes, larger bubbles are intercepted and absorbed, preventing the exiting water from containing larger bubbles. This effectively separates water vapor. After these larger bubbles settle on the tubes, they are washed away by the subsequent water flow, breaking them into smaller bubbles that then exit the tubes, re-enter the water, and flow out through the outlet.

[0017] The fixed ring of the honeycomb tube is designed with a central through hole and offset edge notches, which can actually be regarded as a turbulent ring, causing the water flow to form a vortex shear force field, thereby improving the effect of breaking larger bubbles; the fixed combination of multiple sections of honeycomb tubes can further improve the adsorption and breaking effect of larger bubbles.

[0018] When the present invention is in operation, the bubbles in the water may not break up all at once. Large bubbles may break into small bubbles, which may then break into even smaller bubbles. Therefore, the present invention has a design where the through-holes gradually decrease in size. That is, the bubbles intercepted and adsorbed become smaller as they go downstream, giving them more opportunities to break up, thereby achieving better results.

[0019] As can be seen from the above description, the hot water of the present invention does not pass through the water vapor separation box during the water discharge process, so the water discharge is not slowed down and the hot water can be provided to the user at a higher flow rate; in fact, high-speed water discharge is more conducive to breaking up larger bubbles adsorbed on the honeycomb tube, which is more in line with the design purpose of the present invention.

[0020] In addition, the present invention retains the gas in the form of smaller bubbles in the water, so that there are still a large number of small bubbles in the hot water flowing out of the water spout. From a visual point of view, it will appear that the hot water is emitting "white smoke", giving the user a psychological feeling that the water temperature is very high, which is more in line with the user's psychological expectations.

[0021] During installation, the honeycomb tube is pre-placed in the hot water pipe; then, the vertical section of the hot water pipe is inserted into the vertical through-hole of the water outlet at an angle perpendicular to its preset position in the horizontal direction, so that the hot water pipe is between the upper limit end and the lower limit platform in the vertical direction, and then rotated 90° in the horizontal direction so that it enters between the upper limit end and the lower limit platform. In this way, when the hot water pipe is installed in place, it is restricted by the upper limit end and the lower limit platform in the vertical direction, so it will not shake up and down; it is restricted by the vertical through-hole of the water outlet in the horizontal direction, so it will not move left and right or forward and backward. As for the swing with the vertical through-hole as the axis, it will not affect its vertical downward posture, so it will not affect its use. Through this set of technical features, it can be ensured that the vertical section of the hot water pipe always remains vertically downward, and the water outlet shape is vertical and stable.

[0022] It can be seen that the present invention does not require the use of a water vapor separation box, and can achieve water vapor separation without damaging the hot water flow rate, so that the water outlet shape is stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] See also Figure 1 、 Figure 6 The hot water tap of this embodiment is installed on the water purifier by the cooperation of the mounting nut 1 and the mounting part 2. The mounting part 2 is vertically arranged, and there is an extension part 3 extending horizontally above it, and the extension part 3 is rotatably connected to the mounting part 2. There is also a display switch 8 above the extension part. It is a prior art that has both display functions and the function of controlling the on and off of each pipeline. It will not be described here. The water in the hot water pipe 6 is heated hot water. The heating body 60 is Figure 6 Shown in.

[0031] The hot water faucet also includes a normal temperature water pipe 5 and a hot water pipe 6, which are laid along the mounting portion 2 and the extension portion 3 and discharge water through a water outlet 4, which is fixedly mounted at the front end of the extension portion 3. The lower housing 7 and the decorative cover 71 cover and conceal the water pipes and the water outlet for decorative purposes.

[0032] See also Figure 2 、 Figure 3 . The water outlet 4 has a water outlet connection part 41, which is fixedly installed on the lower surface of the extension part 3 by screws 00; the hot water pipe 6 has a hot water pipe connection part 61, which is also fixedly installed on the lower surface of the extension part 3 by screws 00. The water outlet 4 has a vertical through hole 42 for the hot water pipe 6 to pass through; it also has a normal temperature water pipe connection end 44 for connecting to the normal temperature water pipe 5, and the other end of the normal temperature water pipe connection end 44 directly discharges normal temperature water through an integrally formed channel. The upper part 43 of the water outlet has a protruding upper limit end 431, and the water outlet also has a lower limit platform 45, and the upper limit end 431 and the lower limit platform 45 overlap in the vertical direction.

[0033] See also Figure 4 The installation method of the hot water pipe and the water outlet is as follows: First, Figure 7 or Figure 8 The honeycomb tube shown is placed in the hot water pipe 6 to Figure 4 As shown in the left figure, the horizontal section 62 of the hot water pipe 6 is kept horizontal, and the vertical section 63 is kept vertical, wherein the horizontal section 62 is perpendicular to the normal temperature water pipe connection end 44 of the water outlet, and the vertical section 63 is aligned with the water outlet through-hole 42. Then press it down to form the posture shown in the middle figure. At this time, the end of the vertical section 63 passes through the water outlet through-hole, and the horizontal section 62 is still perpendicular to the normal temperature water pipe connection end 44 of the water outlet, but is lower than the upper limit end 431 of the upper part 43 of the water outlet. Then rotate the horizontal section 62 horizontally 90° to form the posture shown in the right figure. At this time, the horizontal section 62 is parallel to the normal temperature water pipe connection end 44 of the water outlet, that is, the preset angle, and the hot water pipe is restricted between the upper limit end 431 and the lower limit platform 45, and cannot shake up and down. At this point, the installation of the hot water pipe and the water outlet is completed, and then they are connected in Figure 2 The method shown is to be installed on the extension part 3 of the hot water tap.

[0034] See also Figure 5 The vertical section 63 of the hot water pipe is inserted into the right side of the water outlet 4, and the left side is a channel for the flow of normal temperature water. A filter screen 51 is provided in the channel. The bottom of the filter screen 51 is stuck on the inner step surface 46 of the water outlet on the one hand, and is contacted by the upper part 43 of the water outlet on the other hand, so that it can neither move upward nor downward, thereby maintaining axial stability.

[0035] See also Figure 7 The honeycomb tube 9 includes two symmetrical honeycomb tube units 91. Each honeycomb tube unit 91 has a fixing ring 93 at its axial end. The honeycomb tube connector 92 is connected to the two honeycomb tube fixing rings 93, thereby fixing the two honeycomb tube units 91 into one body. The walls of the honeycomb tube unit 91 and the connector 92 are both provided with a large number of through holes. One end of the honeycomb tube unit 91 is an opening 910, and the fixing ring 93 connected to the other end has a central opening 930. The opening 931 of the fixing ring is smaller than the opening 910 of the honeycomb tube. The edge of the fixing ring 93 is an interference fit with the hot water pipe 6, and its edge also has a plurality of notches 931. These notches 931 are concentrated within a 180° circumference of the fixing ring.

[0036] As can be seen in the figure, the notches 931 on the two retaining rings are out of phase, even exactly 180° apart. That is, the notches on one retaining ring are distributed within one 180° of the circumference, while the notches on the other retaining ring are distributed within the other 180°. Therefore, water flowing through the notches in the first retaining ring must form a vortex in the circumferential direction before entering the edge notches or central through-hole of the second retaining ring.

[0037] See also Figure 8 The figure shows another honeycomb tube unit 91. The through-holes 911 on its tube wall are arranged in a gradient pattern, with a diameter of 0.8-1.2 mm on the right end and gradually decreasing to 0.3-0.5 mm on the left end. This creates a gradient field that gradually increases pressure and breaks up bubbles. When only one of these honeycomb tube units is installed in a hot water pipe, the water flows from right to left. If multiple units are installed, the water flows from the last honeycomb tube unit from right to left.
