Description

Technical Field

[0001] The invention relates to the technical field of electric water heater accessories, and in particular to an electric shock-proof wall for a water heater. Background Art

[0002] The electric water heater anti-electric wall is a device that uses the water resistance attenuation isolation method to protect the safety of users, which can fully ensure people's bathing safety.

[0003] The water outlet structure of the existing water heater anti-electricity wall is usually formed by a distributed arrangement of several circular holes. For example, the patent document with the announcement number "CN218410315U" discloses an anti-electricity wall, and its description includes "the water outlet portion includes a laminar flow section, and the laminar flow section is provided with a plurality of first water outlets, and the first water outlets are connected to the inner tank of the water heater, and the water outlet areas of the plurality of first water outlets increase in the axial direction of the water inlet component along the direction close to the water heater input port". Combined with the drawings of the comparative document, it can be seen that the water outlet on the water inlet sleeve is in the shape of a circular hole. Therefore, the shape of the cold water discharged from the water outlet is columnar. When the columnar cold water is discharged into the hot water tank, it will produce a more intense collision with the hot water in the hot water tank, which makes the hot water at the bottom of the hot water tank easy to cool down, thereby resulting in a relatively low hot water output rate when the user uses it, that is, the temperature of the hot water is easy to drop during the user's use of hot water, affecting the user's experience.

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] First embodiment: See also Figure 1-Figure 9 The electric shock-proof wall of the water heater includes a joint body 1, a water inlet 11 is arranged on the lower side of the joint body 1, a water inlet sleeve 2 is connected to the upper side of the joint body 1, a water inlet chamber 21 is formed on the inner side of the water inlet sleeve 2, the water inlet chamber 21 is communicated with the water inlet 11, the water inlet chamber 21 is connected with a water outlet, the water in the water inlet chamber 21 can be discharged outward through the water outlet and form a water curtain that spreads out in a planar manner and tilts downward, the planar water flow has a larger contact area with the hot water in the water tank, and the flow rate is relatively slow compared to the columnar water flow, the water flow of cold water entering the water tank sinks relatively smoothly to the bottom of the water tank, so that the cold water in the water tank is slowly raised, and the hot water on the water tank can flow out to the maximum extent, so that the hot water output rate can be relatively improved, thereby improving the user experience.

[0037] Preferably, an anti-electric wall water pipe is provided on the inner side of the water inlet casing 2 .

[0038] Furthermore, the water outlet is arranged at the side wall of the water inlet sleeve 2, and the water outlet includes a plurality of water outlet holes 22 opened in the horizontal direction along the side wall of the water inlet sleeve 2. The water outlet holes 22 are non-circular hole structures in the shape of long holes, so that the water outlet effect is more uniform, avoiding the cold water from being concentrated at the same position to contact the hot water, and further reducing the influence of the cold water on the hot water at the bottom of the water tank.

[0039] In this embodiment, the water outlet hole 22 is in the shape of a long hole. The water outlet area of ​​the long hole 22 is larger than that of the round hole. When the same flow rate of water passes through the water outlet hole 22, the speed at which the water is discharged outward is relatively slow, which can further slow down the speed at which the cold water and the hot water come into contact. The flow of cold water entering the water tank can sink to the bottom of the water tank more smoothly.

[0040] Furthermore, the water outlet portion is arranged at the side wall of the water inlet casing 2 , and the water outlet portion includes a plurality of water outlet holes 22 opened along the side wall of the water inlet casing 2 , and the water outlet holes 22 are non-circular hole shapes.

[0041] Furthermore, the water outlet hole 22 is a long strip hole or an arc hole or a wavy hole or a combination of long strip holes, arc holes and wavy holes, which can be selected and combined according to actual production needs. Of course, as an equivalent transformation, in other different embodiments, the shape of the water outlet hole 22 can also be other shapes that can make the water flow spread out in a planar shape and tilt downward to form a water curtain.

[0042] Furthermore, the water outlet hole 22 is opened circumferentially along the side wall of the water inlet sleeve 2, the circumferential length of the water outlet hole 22 is L1, the circumference of the water inlet sleeve 2 is L2, L1:L2=L, 0.6≤L≤0.8, the length of the water outlet hole 22 is relatively long, which can ensure that a wider surface is formed when the cold water flows out, making it easier to form the required water curtain.

[0043] Furthermore, a plurality of water outlet holes 22 corresponding to the same horizontal height on the water inlet sleeve 2 form a water outlet ring structure, and a plurality of water outlet ring structures are vertically distributed on the side wall of the water inlet sleeve 2. The water outlet holes 22 of adjacent water outlet ring structures are vertically staggered, and the vertical spatial position of the water inlet sleeve 2 can be further utilized so that the cold water can be discharged outward in layers, thereby further reducing the speed at which the cold water contacts the hot water, thereby further reducing the influence of the cold water on the hot water at the bottom of the water tank.

[0044] Moreover, when water is discharged from the water outlet, the pressure of the lower water outlet ring structure is greater than the pressure of the upper water outlet ring structure, so it is easier to form a water curtain that is narrow at the top and wide at the bottom.

[0045] Furthermore, a buffer sleeve 3 is provided on the outer side of the water inlet sleeve 2, and a plurality of buffer water holes 31 are distributed on the side wall of the buffer sleeve 3. The buffer water holes 31 overlap with the water outlet holes 22 at least partially in the horizontal direction. The buffer sleeve 3 can further reduce the speed of cold water discharged from the buffer water holes 31.

[0046] Furthermore, a plurality of buffer water holes 31 corresponding to the same horizontal height on the buffer sleeve 3 form a buffer water ring structure, and a plurality of buffer water ring structures are vertically distributed on the side wall of the buffer sleeve 3. The buffer water holes 31 of adjacent buffer water ring structures are vertically staggered, so that the cold water can be discharged outward in layers, thereby further reducing the speed at which the cold water contacts the hot water, thereby further reducing the influence of the cold water on the hot water at the bottom of the water tank.

[0047] Furthermore, a water injection circumferential surface is formed on the side wall of the water inlet sleeve 2, and the water outlet is arranged on the water injection circumferential surface. The position on the water injection circumferential surface relative to the outside of the water outlet is closed. The surface area of ​​the water outlet is S1, and the closed area of ​​the water injection circumferential surface is S2. S1:S2=S, 0.3≤S≤0.7. The surface area of ​​the water outlet is relatively large. When the same flow rate of water passes through, the speed at which water flows out through the water outlet is relatively slow.

[0048] Second embodiment: See also Figure 10-12The difference between this embodiment and the first embodiment is that a buffer net 4 is provided on the outer side of the water inlet sleeve 2 of the electric shock-proof wall of the water heater, and a plurality of water outlet mesh holes 41 are distributed on the buffer net 4. At least part of the water outlet mesh holes 41 overlap with the water outlet holes 22 in the horizontal direction. The buffer net 4 can further reduce the speed of cold water contacting hot water, thereby further reducing the influence of cold water on the hot water at the bottom of the water tank.

[0049] Furthermore, a radial distance is formed between the buffer net 4 and the water inlet sleeve 2, forming a water outlet gap 42 therebetween. The buffer net 4 can also allow part of the cold water to flow to the hot water tank through the water outlet gap 42, thereby further diverting the cold water.

[0050] Furthermore, a thickened portion 23 is provided on the outer side of the water inlet sleeve 2 at a position above the water outlet hole 22, and the thickened portion 23 is concentrically arranged with the water inlet sleeve 2. The buffer sleeve net 4 part is tightly matched with the thickened portion 23 to form a water outlet gap 42 between the buffer sleeve net 4 and the water inlet sleeve 2. The thickened portion 23 can make the buffer sleeve net 4 and the water inlet sleeve 2 maintain concentricity, so that the structure of the water outlet gap 42 is more stable, and the aperture of the water outlet mesh 41 is relatively small, and it is easy to be blocked by scale after long-term use, affecting the normal discharge of cold water. At this time, the cold water can still be discharged outward from the water outlet gap 42, so as to minimize the adverse effects caused by scale blockage.

[0051] The remaining undescribed parts are the same as those of the first embodiment and will not be repeated here.

[0052] Third embodiment: See also Fig.13 The difference between this embodiment and the second embodiment is that a buffer sleeve net 4 is provided on the outer side of the buffer sleeve 3 of the electric shock-proof wall of the water heater.

[0053] The remaining undescribed parts are the same as those of the first embodiment and will not be repeated here.

[0054] Fourth embodiment: See also Fig.14 The difference between this embodiment and the first embodiment is that the water outlet holes 22 of the electric shock-proof wall of the water heater are vertically opened along the side wall of the water inlet sleeve 2, and a spacing is formed between adjacent water outlet holes 22 along the circumferential direction.

[0055] The remaining undescribed parts are the same as those of the first embodiment and will not be repeated here.

[0056] Fifth embodiment: See also Fig.15The difference between this embodiment and the first embodiment is that: the water inlet sleeve 2 of the electric shock-proof wall of the water heater is provided with a first hole group and a second hole group, the first hole group includes a plurality of water outlet holes 22 circumferentially opened along the side wall of the water inlet sleeve 2, the second hole group includes a plurality of water outlet holes 22 vertically opened along the side wall of the water inlet sleeve 2, the first hole group and the second hole group are arranged adjacent to each other vertically, the water flows generated by the first hole group and the second hole group are respectively called horizontal surface shapes and vertical surface shapes, which can interfere with each other and break up, so that the water flow sinks more smoothly when entering the water tank, reducing the chance of interacting with hot water, thereby further improving the hot water output rate of the water heater.

[0057] The remaining undescribed parts are the same as those in the first embodiment and will not be repeated here.

[0058] The above embodiments are only preferred embodiments of the present invention, and the present invention may have other embodiments. Those skilled in the art may also make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope set by the claims of this application.
