Description

Technical Field

[0001] This utility model belongs to the field of water purifier technology, and in particular relates to a water purifier that can provide hot water. Background Technology

[0002] Most modern water purifiers come with a heating function. The filtered water can be dispensed at room temperature or heated. Obviously, a hot water pipe is needed in the water purifier to provide the heated water to the user. However, heated water inevitably contains air bubbles. The presence of air bubbles causes the hot water to flow out of the spout in an unstable pattern, such as a fan-shaped flow or splashing. This not only affects the appearance but also poses a risk of scalding the user.

[0003] To address this issue in existing technologies, a water vapor separator is installed in the hot water pipe to allow gas in the hot water to escape without affecting the water flow pattern. The applicant has previously applied for several patents in this area, such as CN210204462U, which discloses a water vapor separator in an instant hot water dispenser. This separator includes a box body with a hollow structure, an inlet on one side, and an outlet at the bottom. The bottom surface of the box body is an inverted cone shape, with the outlet located at the lowest point of the cone. The box body also includes an exhaust channel formed by a baffle plate. The exhaust channel is cylindrical, with an air inlet at the top and an exhaust outlet at the bottom. The air inlet at the top of the exhaust channel is higher than the water inlet. It has an exhaust channel inside the water vapor separation box. The exhaust channel is in a circular shape, separating the incoming hot water and water vapor. The air inlet at the top of the exhaust channel is higher than the water inlet, which prevents hot water from directly entering the exhaust channel. The exhaust pipe can also block the impact of incoming water, so that the water falls directly above the water outlet, reducing the water flow path. The water vapor enters the exhaust channel and is discharged from the exhaust port below.

[0004] For example, CN210582215U discloses a jet-type water vapor separator, including a box body with a hollow structure. One side of the box body has a cold water inlet and a hot water inlet, and the lower end has an outlet. The bottom surface of the box body is an inverted cone shape, with the outlet located at the lowest point of the inverted cone. The box body also has an exhaust channel with an exhaust port at its bottom. The hot water inlet is inclined downwards, with its lowest point connected to the interior of the box body. The inclination angle of the hot water inlet is 8-15 degrees, which is the angle between the hot water inlet and the horizontal line. This structure, with its downward-sloping hot water inlet and inverted cone bottom, allows excess water to fall quickly due to gravity, thus reducing dripping.

[0005] CN216602490U also discloses a water vapor separator, including a box body with a water inlet on one side and a water vapor outlet on the other side. The water inlet and water vapor outlet are connected by a ramp, with the water vapor outlet located at the lowest point of the water vapor separator. A heating device is located next to the water inlet, and the box body is integrally connected to the heating device. Inside the box body is a V-shaped baffle layer, the endpoint of which overlaps with the center of the water vapor outlet, and the two wings extend backward to intersect with the side wall of the box body. The pointed end of the V-shaped baffle layer is hollowed out, and with its endpoint as the center, it forms a circular water outlet with a radius smaller than that of the water vapor outlet. The portion of the water vapor outlet that does not intersect with the V-shaped baffle layer and the water outlet forms a fan-shaped annular exhaust port. This water vapor separator can fully separate water vapor while ensuring that the water flows straight and smoothly under different flow rates, reducing splashing and minimizing safety hazards.

[0006] The principles behind the aforementioned literature and other existing technologies on the market are all based on allowing hot water to linger during the outflow process, combined with the specific shape design of the water-vapor separator to allow the gas in the hot water to escape. The drawbacks of existing technologies are that the flow rate of the hot water decreases after passing through the water-vapor separator; furthermore, the water-vapor separator has a complex structure and high manufacturing costs. Summary of the Invention

[0007] The purpose of this invention is to provide a water purifier that can provide hot water without the need for a water vapor separator.

[0008] The technical solution adopted by this utility model is as follows: a water purifier that can provide hot water includes 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; characterized in that: at least one section of honeycomb tube is provided inside the hot water pipe, which is installed inside the hot water pipe by interference fit with the wall of the hot water pipe through a fixing ring; the main body of the honeycomb tube is in the shape of a round tube, and several through holes are opened on the wall of the honeycomb tube.

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

[0010] The aforementioned notches are concentrated within a fan-shaped area of ​​less than 180° on the edge of the fixing ring.

[0011] Furthermore, the hot water pipe contains multiple honeycomb tubes, which are fixedly connected to each other by connectors.

[0012] The connector has several through holes.

[0013] In the honeycomb tube or multi-segment honeycomb tube, the downstream segment of the honeycomb tube in the direction of water flow has a through hole diameter that gradually decreases in size along the direction of water flow.

[0014] This utility model can also adopt the following technical solution: the water outlet has a vertical through hole for the vertical section of the hot water pipe to pass through; 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] Through long-term research, the applicant discovered that gases dissolved in pure water exist in the form of microbubbles. Upon heating, these bubbles aggregate to form larger bubbles. This process does not occur suddenly, but rather involves microbubbles first aggregating into smaller bubbles, and then further aggregating into larger bubbles. It is the presence of these larger bubbles that affects the water flow pattern, causing the problems described in the background section; as for the smaller bubbles, they do not actually affect the water flow pattern. Roughly speaking, a particle size of 0.5 mm can be considered a dividing line; only bubbles larger than 0.5 mm affect the water flow pattern.

[0016] The honeycomb tube in this invention is equivalent to forming a grid in the water channel. When water containing air bubbles flows through the honeycomb tube, larger air bubbles in the water are intercepted and adsorbed, thus preventing the water from containing large air bubbles, effectively achieving water vapor separation. After these larger air bubbles remain on the honeycomb tube, they are broken up by the subsequent water flow, becoming smaller air bubbles that can then leave the honeycomb tube, re-enter the water, and flow out through the outlet.

[0017] The fixing ring of the honeycomb tube is designed with a central through hole and an offset edge notch, which can actually be regarded as a turbulence ring, so that the water flow forms a vortex shear force field, which improves the breaking effect of larger air bubbles; the use of multiple honeycomb tubes in a fixed combination can further improve the adsorption and breaking effect of larger air bubbles.

[0018] In operation, the breakup of air bubbles in water may not be a one-time event; large bubbles may break into smaller bubbles, and these smaller bubbles may break into even smaller bubbles. Therefore, this invention features a design with a decreasing gradient in the through-holes, meaning that the bubbles intercepted and adsorbed become smaller as they move downstream, giving them more opportunities to break up and thus achieving better results.

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

[0020] In addition, this invention retains the gas in the form of small bubbles in the water, so that the hot water flowing from the spout still contains a large number of small bubbles. Visually, this makes the hot water appear to be emitting "white smoke," giving users the psychological feeling that the water temperature is very high, which is more in line with users' psychological expectations.

[0021] In this invention, during installation, the honeycomb tube is pre-inserted into 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 predetermined position in the horizontal direction, positioning the hot water pipe vertically between the upper and lower limit plates. It is then rotated 90° horizontally to reposition itself between the upper and lower limit plates. Thus, once the hot water pipe is in place, it is restricted vertically by the upper and lower limit plates, preventing vertical swaying; and horizontally, it is restricted by the vertical through-hole of the water outlet, preventing lateral or forward / backward displacement. Any oscillation around the vertical through-hole does not affect its vertically downward orientation and therefore does not affect its use. This set of technical features ensures that the vertical section of the hot water pipe always remains vertically downward, resulting in a vertical and stable water outlet.

[0022] It is evident that this invention does not require a water vapor separation box and can achieve water vapor separation without damaging the hot water flow rate, resulting in a stable water output pattern. Attached Figure Description

Detailed Implementation

[0030] See Figure 1 , Figure 6 In this embodiment, the hot water faucet is mounted on the water purifier via the cooperation of the mounting nut 1 and the mounting part 2. The mounting part 2 is vertically arranged, with a horizontally extending extension 3 above it, and the extension 3 is rotatably connected to the mounting part 2. Above the extension is a display switch 8, which is existing technology and has both display and control functions for the on / off of various pipes; details are omitted here. The water in the hot water pipe 6 is preheated hot water, and the heating element 60... Figure 6 As shown in the image.

[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 part 2 and the extension part 3, and water flows out through the spout 4, which is fixedly installed at the front end of the extension part 3. The lower housing 7 and the decorative cover 71 cover and hide the water pipes and spout, serving a decorative purpose.

[0032] See Figure 2 , Figure 3 The water outlet 4 has a water outlet connector 41, which is fixedly installed on the lower surface of the extension 3 by screws 00; the hot water pipe 6 has a hot water pipe connector 61, which is also fixedly installed on the lower surface of the extension 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 connector 44 for connecting a normal temperature water pipe 5, and the other end of the normal temperature water pipe connector 44 directly outputs 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, the upper limit end 431 and the lower limit platform 45 overlapping in the vertical direction.

[0033] See Figure 4 The installation method for hot water pipes and faucets is as follows: First, connect... Figure 7 or Figure 8 The honeycomb tube shown is inserted into the hot water pipe 6, so as... Figure 4As shown in the left figure, keep the horizontal section 62 of the hot water pipe 6 horizontal and the vertical section 63 vertical. The horizontal section 62 is perpendicular to the room temperature water pipe connection end 44 of the outlet, and the vertical section 63 is aligned with the 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 outlet through hole, and the horizontal section 62 is still perpendicular to the room temperature water pipe connection end 44 of the outlet, but it is lower than the upper limit end 431 of the upper part 43 of the outlet. Then rotate the horizontal section 62 horizontally by 90° to form the posture shown in the right figure. At this time, the horizontal section 62 is parallel to the room temperature water pipe connection end 44 of the outlet, i.e., the preset angle, and the hot water pipe is restricted between the upper limit end 431 and the lower limit platform 45, and cannot be shaken up and down. The installation of the hot water pipe and the outlet is now complete. Figure 2 Install it onto the extension 3 of the hot water faucet as shown.

[0034] See Figure 5 The right side of the water outlet 4 has a vertical section 63 of hot water pipe inserted, and the left side is a channel for room temperature water to flow out. A filter screen 51 is installed in this channel. The bottom of the filter screen 51 is stuck on the inner stepped surface 46 of the water outlet on one hand, and is pushed against 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 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 unit. The walls of the honeycomb tube unit 91 and the connector 92 have 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 press-fitted with the hot water pipe 6 to form a locking fit. Its edge also has several notches 931, which are concentrated within a 180° circumference of the fixing ring.

[0036] As shown in the diagram, the notches 931 on the two fixed rings are out of phase and even exactly 180° apart. That is, the notches on one fixed ring are distributed within one 180° of the circumference, and the notches on the other fixed ring are distributed within another 180°. Therefore, the water flow passing through the notch of the first fixed ring must form a vortex in the circumferential direction in order to enter the edge notch or the central through hole of the second fixed ring.

[0037] See Figure 8The figure shows another type of honeycomb tube unit 91, whose through holes 911 on the tube wall are arranged in a gradient, with the diameter of the holes at the right end being 0.8-1.2 mm, gradually decreasing to 0.3-0.5 mm at the left end, forming a gradient field for progressively pressurized and broken air bubbles. When this type of honeycomb tube unit is installed in a hot water pipe, if only one is installed, the water flow direction is from right to left; if multiple are installed, the water flow direction of the last honeycomb tube unit is from right to left.
