Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
First embodiment, as shown in fig. 1 to 2, the present embodiment provides a water inlet pipe for a water heater, which includes a pipe body 1, a sleeve 2 and a buffer net 3. One end part of the pipe body 1 is provided with a water inlet 11, and the other end part of the pipe body 1 is provided with a water outlet 12; the sleeve 2 is provided with a plurality of water outlet holes 21, the sleeve 2 is sleeved outside the pipe body 1, the water outlet holes 21 are arranged close to the water inlet 11, a water flow channel 10 is formed between the sleeve 2 and the pipe body 1, and the water outlet 12 and the water outlet holes 21 are communicated with the water flow channel 10; the buffer net 3 is sleeved outside the pipe body 1 and shields the water outlet hole 21.
In actual use, the water inlet pipe is assembled on a water tank of the water heater in a conventional mode, the water inlet 11 is exposed outside the water tank, and the water outlet 12, the sleeve 2 and the buffer net 3 are positioned inside the water tank. During the water inlet process through the water inlet 11, external cold water enters the tank body through the pipe body 1, and the cold water output from the water outlet hole 21 flows to the bottom of the tank due to the proximity of the water outlet hole 21 to the bottom of the tank.
In the process that cold water flows out of the water inlet pipe, the cold water is firstly output from the water outlet 12 and enters the water flow channel 10, and the high-speed water flow output from the water outlet 12 can be subjected to primary buffering treatment by utilizing the water flow channel 10 between the sleeve 2 and the pipe body 1. Cold water continues to flow in the water flow channel 10 and will be exported to the inside of the water tank via the apopore 21, and in the process of cold water flowing out via the apopore 21, because the aperture of the apopore 21 is less, can play the effect of buffering the water velocity again. More importantly, utilize the buffering net 3 can be more effective to rivers slow down to ensure that the bottom of water tank can effectual dispersion to the water that flows from the inlet tube, reduce the hot-water influence in water tank upper portion, in order to satisfy the requirement to hot water output rate.
In the actual assembling process, the water inlet pipe is only installed on the water tank in a conventional assembling mode, and the water baffle is not additionally arranged in the water tank, so that the assembling difficulty of the water tank can be effectively simplified, and the assembling efficiency of the water heater is improved.
There are various structural forms for the specific installation position of the buffer net 3. In one embodiment, as shown in fig. 1-2, the buffer net 3 is sleeved outside the sleeve 2, the buffer net 3 is abutted against the outer pipe wall of the sleeve 2, and the buffer net 3 can be sleeved directly outside the sleeve 2 in a net-sleeved manner, in which case, the buffer net 3 can be a hard net or a flexible net.
Alternatively, in another embodiment, as shown in fig. 3-4, the buffer net 3 is disposed between the casing 2 and the tubular body 1, the buffer net 3 is abutted against the inner wall of the casing 2, and the buffer net 3 is installed in the casing 2 in advance; then, the sleeve 2 is sleeved outside the tube body 1, and in this case, the buffer net 3 is preferably a hard net. Preferably, as shown in fig. 5, in the case where the buffer mesh 3 is arranged against the inner pipe wall of the casing 2, the buffer mesh 3 is injection molded integrally with the casing 2.
In some embodiments, the cushioning net 3 will completely cover the outlet holes 21 formed in the casing 2, so that the inlet water can be more effectively cushioned by the cushioning net 3. In some embodiments, the buffering net 3 can only cover part of the water outlet holes 21, so that the requirement of buffering water inflow is met, and meanwhile, the water inflow speed is high, so that the requirement of outputting hot water quickly is met.
As a preferred embodiment, taking the example that the water inlet pipe is vertically arranged in the water tank, the lower edge of the buffer net 3 is lower than the water outlet hole 21 at the lowest position of the sleeve 2; while the upper edge of the cushioning net 3 is below the highest positioned outlet hole 21 of the casing 2. And the number of the water outlet holes 21 in the position is 20-500 meshes, preferably 50-150 meshes.
In some embodiments, in order to facilitate assembly of the water inlet pipe, the water inlet pipe may further include a plug 4, specifically, the water outlet 12 is disposed on a pipe wall of the pipe body 1, and a first pipe orifice of the water inlet pipe forms the water inlet 11; the plug 4 is inserted in the second orifice of the water inlet pipe and the third orifice of the sleeve 2 in a sealing way. Specifically, after the sleeve 2 is sleeved on the pipe body 1, the second nozzle of the water inlet pipe and the third nozzle of the sleeve 2 are in a flush or approximately flush state, so that the second nozzle of the water inlet pipe and the third nozzle of the sleeve 2 can be simultaneously sealed by the plug 4 to form the water flow channel 10 between the sleeve 2 and the pipe body 1. Wherein, for the convenience to install the inlet tube on the water tank, then body 1 is provided with mount pad 13, and the outer periphery of mount pad 13 is provided with external screw thread (unmarked), and mount pad 13 is close to water inlet 11, and the inlet tube links together through the corresponding screw hole of mount pad 13 with the water tank after inserting into the water tank. Correspondingly, the fourth opening of the sleeve 2 abuts against the mounting seat 13, so that the water flow channel 10 forms a relatively closed flow channel, and water can be discharged outwards only through the water outlet hole 21.
An embodiment two, the utility model provides a water heater, including the water tank, then install the inlet tube in above-mentioned embodiment on the water tank.
In the present embodiment, the specific structural form of the water heater is not limited herein, and for the water inlet pipe for the water heater, it can be installed on the water tank to realize water inlet of the water tank.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
