[0002] The water heater generally has the function of heat storage, and the heat storage device is used to store heat so that the user can get hot water in time. There are many types of heat storage devices, and the phase change medium is favored due to its high heat storage density, so the phase change medium is used as the heat storage material of the water heater and is applied more and more widely.

[0003] When the phase change medium is used as the heat storage device, the thermal conductivity is low, so the heat exchange between the phase change medium and the heat exchange device is generally realized through the heat exchange fins. The two ends of the heat exchange device are formed with bending sections. The bending sections are not distributed with the heat exchange fins, so the heat charging and discharging rate of the bending sections is very slow, the heat exchange capacity is poor, and the influence on the heat storage and heat discharging capacity of the system is very small. Therefore, the utilization rate of the phase change medium corresponding to the position of the bending section is low. SUMMARY

[0004] The utility model discloses a water heater, to solve the low heat exchange efficiency of the phase change medium in the existing water heater in the prior art, the large filling amount of the phase change medium, the heavy weight of the water heater and other problems.

In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the utility model.

In addition, the utility model provides examples of various specific processes and materials, but those skilled in the art can realize the application of other processes and / or the use of other materials.

[0060] Reference Figures 1-8 In one aspect, the utility model provides a water heater, it includes shell 100, inner bag 200, phase change medium, heat exchange device 500 and barrier 600, the installation inner cavity is formed in shell 100, inner bag 200 is arranged in the installation inner cavity, and the heat preservation gap is formed between inner bag 200 and shell 100, and the heat preservation layer 300 is arranged in the heat preservation gap, for reducing the heat exchange of inner bag 200 and the outside.

[0061] The heat exchange inner cavity is formed in inner bag 200, and the phase change medium is located in the heat exchange inner cavity, and the specific reference Figure 8 Heat exchange device 500 is located in phase change medium, and heat exchange device 500 includes heat storage pipeline 510, heat release pipeline 520 and heat exchange fin, and heat storage pipeline 510 passes through heat exchange fin and transmits the heat of high-temperature water from heat pump, solar energy or gas to phase change medium and stores.

[0062] When the user uses hot water, the phase change medium heats the low-temperature water in heat release pipeline 520 through heat exchange fin and then outputs, for the user to use.

[0063] The specific reference Figure 4 Heat storage pipeline 510 and heat release pipeline 520 all include bending section 502 and straight section 501, and heat exchange fin is arranged between straight section 501.

[0064] The heat exchange device 500 does not set the heat exchange fins at the position corresponding to the bending section 502. The traditional water heater also fills the phase change medium between the bending section 502 of the heat exchange device 500 and the inner container 200. The heat exchange efficiency of the phase change medium and the bending section 502 is very low. When the temperature of the phase change medium filled at the heat exchange fin position rises to the set temperature, the phase change medium at the heat exchange fin position is still slowly exchanged with the phase change medium at the position of the bending section 502, which reduces the heat storage capacity of the phase change medium filled at the heat exchange fin position. In addition, during the heat release process, the heat exchange efficiency of the phase change medium corresponding to the bending section is poor, which causes the phase change medium at the heat exchange fin position to be completely released after the heat release, and even the phase change medium corresponding to the bending section is still at a high temperature. The water temperature output from the output end of the heat release pipeline 520 cannot meet the use requirement.

[0065] In other words, the heat exchange effect of the phase change medium corresponding to the bending section 502 during the heat exchange process is low, which belongs to invalid heat exchange.

[0066] In order to reduce the phase change medium filled in the above invalid heat exchange area, the application sets a barrier piece 600 between the heat exchange device 500 and the inner container 200. The barrier piece 600 is specifically set on at least one side of the heat exchange device 500 corresponding to the bending section, and is used to fill the gap between the corresponding bending section and the inner container 200 on the side, and reduce the filling of the phase change medium at the position.

[0067] Of course, the two sides of the heat exchange device 500 can be respectively provided with a barrier piece 600, which respectively protects and blocks the corresponding bending sections on the two sides.

[0068] Specifically refer to Figure 5 , Figure 6 Specifically, the barrier piece 600 is in a plate structure as a whole. The barrier piece 600 is set between the heat exchange device 500 and the inner container 200. A containing recess 610 is formed on the side of the barrier piece 600 in contact with the heat exchange device 500. The bending section 502 is at least partially located in the containing recess 610.

[0069] In some embodiments of the application, the containing recess 610 is an integral groove structure provided on the barrier piece 600. The peripheral side of the containing recess 610 is a butt joint outer edge. The butt joint outer edge is in butt joint with the side surface of the heat exchange device 500. Each bending section 502 on the side surface of the heat exchange device 500 extends into the containing recess 610.

[0070] The containing recess 610 on the barrier piece 600 is provided as an integral structure, which is convenient for processing and forming, and is convenient and fast for installation and positioning, and has small operation difficulty.

[0071] In other embodiments, the containing recess 610 is a long strip-shaped groove extending along the height direction of the inner container 200. The number of containing recesses 610 can be designed as multiple according to the actual design.

[0072] In addition to being arranged outside the corresponding position of the bending section 502, the heat storage pipeline 510 and the heat release pipeline 520 exposed outside the heat exchange device 500 can also pass through the accommodating recess 610, thereby limiting and protecting the pipeline section.

[0073] In other embodiments, the number of accommodating recesses 610 corresponds to the number of bending sections 502, and the shape of the accommodating recess 610 is matched with the shape of the bending section 502.

[0074] Specifically, the accommodating recess 610 is arranged in an array on the barrier 600, and the number of the accommodating recess 610 corresponds to the number of the bending sections 502. During installation, the barrier 600 is first positioned on the corresponding side of the heat exchange device 500, and then the heat exchange device 500 and the barrier 600 are placed in the phase change medium.

[0075] The above-mentioned forming mode of the accommodating recess 610 is more conducive to the cladding of the bending section 502, and the stability of the connection is stronger.

[0076] In some embodiments of the present application, the bending section 502 is in a circular arc shape, and correspondingly, the shape of each accommodating recess 610 is also a groove shape with an arc-shaped bottom surface matched with the shape of the bending section 502.

[0077] When the bending section 502 is in other shapes, the accommodating recess 610 is also a groove matched with the shape of the bending section 502.

[0078] The barrier 600 is cladded outside the bending section 502, fills the space between the outside of the bending section 502 and the inner container 200, can reduce the filling amount of the phase change medium, is conducive to reducing the cost and reducing the weight of the water heater, reduces the heat exchange inefficient area corresponding to the bending section 502, and improves the heat exchange efficiency between the phase change medium and the heat exchange device 500.

[0079] In addition, the barrier 600 also provides protection between the bending section 502 and the inner container 200. Before the heat exchange device 500 is installed in the inner container 200, the barrier 600 is first fixed on the bending section 502. During the installation process of the heat exchange device 500, the barrier 600 also protects the bending section 502, thereby avoiding collision between the bending section 502 and the inner container 200.

[0080] In some embodiments of the present application, the material of the barrier 600 is plastic, which is arranged on both sides of the heat exchange device 500 and used for cladding the bending section.

[0081] In some embodiments of the present application, the density of the barrier 600 is less than the density of the phase change medium, so as to reduce the weight of the water heater.

[0082] The barrier 600 is made of plastic with a density less than that of the phase change medium, which is conducive to reducing the amount of phase change medium added, and thus reducing the weight of the entire water heater.

[0083] Referring again to Figure 8 In some embodiments of the present application, the heat storage pipeline 510 includes a heat storage input end 511 and a heat storage output end 512, and the heat release pipeline 520 includes a heat release input end 521 and a heat release output end 522. The heat storage input end 511, the heat storage output end 512, the heat release input end 521, and the heat release output end 522 are connected to the shell 100 through the adapter joint 530.

[0084] The heat pump, solar energy, and gas energy transport the high-temperature water heated to the heat storage pipeline 510 through the heat storage input end 511, and the heat is transferred to the phase change medium through the heat exchange fins for storage. When used, the low-temperature water is transported to the heat release pipeline 520 of the heat exchange device 500 through the heat release input end 521, and the heat in the phase change medium is transferred to the heat release pipeline 520 through the heat exchange fins. The low-temperature water in the heat release pipeline 520 is heated and then output to the user terminal through the heat release output end 522.

[0085] Referring specifically to Figure 2 , Figure 3 In some embodiments of the present application, the outer wall of the inner container 200 is further provided with a reinforcing member 400, which is used to improve the structural strength of the inner container 200.

[0086] Because the phase change medium has high latent heat, the heat absorption and heat release processes of the phase change medium are accompanied by volume changes. When the phase change medium changes, it mainly relies on the pressure-bearing capacity of the inner container 200, and the reinforcing member 400 provided outside the inner container 200 is conducive to improving the structural strength of the inner container 200 and reducing the deformation of the inner container 200 during the volume change of the phase change medium.

[0087] In some embodiments of the present application, the reinforcing member 400 includes at least two reinforcing cross frames 410 arranged on the outer wall of the inner container 200 along the height direction of the inner container 200.

[0088] The reinforcing cross frames 410 are arranged at intervals, which can reinforce different positions of the inner container 200, improve the overall structural strength of the inner container 200, and reduce the risk of deformation.

[0089] In some embodiments of the present application, the reinforcing cross frame 410 is a frame structure, and the reinforcing cross frame 410 is arranged around the outer periphery of the inner container 200 along the horizontal direction.

[0090] The reinforcing cross frame 410 is arranged around the outer periphery of the inner container 200, which can reinforce the entire periphery of the inner container 200 and avoid the occurrence of bulging and depression at the unreinforced positions of the periphery of the inner container 200.

[0091] In some embodiments of the present application, specific reference is made to Figure 9 , Figure 10 The bottom of the shell 100 is connected to the fixed base 700 through supports 710, the number of the supports 710 is at least two, each support 710 comprises a support bottom 711, a support vertical portion 712 formed on both sides of the support bottom 711 and perpendicular to the support bottom 711, and a support horizontal portion 713 formed on the support vertical portion 712, the support bottom 711 is detachably connected to the fixed base 700, and the bottom of the shell 100 is detachably connected to the support horizontal portion 713.

[0092] Specifically, the support bottom 711, the support vertical portion 712 and the support horizontal portion 713 are integrally formed, and the support bottom 711 is provided with a connecting hole, which is specifically a long strip-shaped hole to avoid connection errors.

[0093] The fixed base 700 is provided with a fixing hole, and the fixed base 700 and the support bottom 711 are connected through fasteners such as fastening bolts.

[0094] On the other hand, the present application also provides a water heater, which comprises a shell 100, an inner container 200, a phase change medium and a heat exchange device 500.

[0095] The shell 100 is formed with a mounting inner cavity, the inner container 200 is arranged in the mounting inner cavity, the inner container 200 is formed with a heat exchange inner cavity, and the phase change medium is located in the heat exchange inner cavity.

[0096] The heat exchange device 500 is located in the phase change medium and comprises heat storage pipelines 510, heat release pipelines 520 and heat exchange fins, the heat storage pipelines 510 and the heat release pipelines 520 each comprise a bending section 502 and a straight section 501, and the heat exchange fins are arranged between the straight sections 501.

[0097] The heat exchange device 500 is further provided with a blocking structure, which is configured to be wrapped outside the bending section 502 to reduce the filling amount of the phase change medium at the corresponding position.

[0098] The blocking structure can be designed in the following ways or in combination of some of the ways.

[0099] In the first way, the blocking structure comprises a plurality of isolation units, each isolation unit is formed with at least one accommodating recess 610, and the accommodating recess 610 corresponds to the bending section 502 one by one.

[0100] That is, a plurality of isolation units can be arranged on one side of the heat exchange device 500, the isolation units can be connected on the heat exchange device 500 in sequence along the height direction or the thickness direction of the heat exchange device 500, the isolation units are provided with the accommodating recess 610, and one isolation unit is connected with at least one bending section 502.

[0101] In some embodiments, the barrier structure is a plate-shaped barrier 600, and a receiving recess 610 is formed on the side of the barrier 600 in contact with the heat exchange device 500, and the bent section 502 is at least partially located in the receiving recess 610.

[0102] The receiving recess 610 on the barrier 600 is provided as an integral structure, which is convenient for processing and shaping, and is convenient and fast for installation and positioning, and has small operation difficulty.

[0103] In other embodiments, the number of receiving recesses 610 is multiple, which corresponds to the bent section 502 one by one, and the shape of the receiving recess 610 is matched with the bent section 502.

[0104] Specifically, the receiving recess 610 is dispersedly arranged on the barrier 600 in an array manner, and the number thereof corresponds to the bent section 502 one by one. When installing, the barrier 600 is first positioned to the corresponding side of the heat exchange device 500, and then the heat exchange device 500 and the barrier 600 are placed in the phase change medium.

[0105] The above forming mode of the receiving recess 610 is more conducive to the cladding of each bent section 502, and the stability of the connection is stronger.

[0106] The barrier 600 is cladded on the outer side of the bent section 502, fills the space between the outer side of the bent section 502 and the inner container 200, can reduce the filling amount of the phase change medium, is conducive to reducing the cost and reducing the weight of the water heater, reduces the heat exchange inefficient area corresponding to the bent section 502, and improves the heat exchange efficiency between the phase change medium and the heat exchange device 500.

[0107] In addition, the barrier 600 also provides protection between the bent section 502 and the inner container 200. Before the heat exchange device 500 is installed into the inner container 200, the barrier 600 is first fixed on the bent section 502. Then, during the installation process of the heat exchange device 500, the barrier 600 also plays a protective role on the bent section 502, avoiding the collision between the bent section 502 and the inner container 200.

[0108] The third mode, the outer wall of the inner container 200 is also provided with a reinforcing member 400, and the reinforcing member 400 is used to improve the structural strength of the inner container 200.

[0109] Since the phase change medium has high latent heat, the heat absorption and heat release processes of the phase change medium are accompanied by volume change. When the phase change medium changes, it mainly depends on the inner container 200 to bear the pressure, and the reinforcing member 400 provided outside the inner container 200 is conducive to improving the structural strength of the inner container 200 and reducing the deformation of the inner container 200 during the volume change of the phase change medium.

[0110] In some embodiments of the present application, the reinforcing member 400 comprises at least two reinforcing cross frames 410 arranged on the outer wall of the inner container 200 at intervals along the height direction of the inner container 200.

[0111] The reinforcing cross frames 410 are arranged at intervals, so that the inner container 200 can be reinforced at different positions, the overall structural strength of the inner container 200 is improved, and the risk of deformation is reduced.

[0112] In some embodiments of the present application, the reinforcing cross frame 410 is a frame structure, and the reinforcing cross frame 410 is arranged around the outer periphery of the inner container 200 along the horizontal direction.

[0113] The reinforcing cross frame 410 is arranged around the outer periphery of the inner container 200, so that the side of the inner container 200 can be reinforced, and the phenomenon of bulging and depression at the unreinforced position of the side of the inner container 200 can be avoided.

[0114] As long as possible, various aspects and features described and illustrated in the specification can be applied alone, and these individual aspects can be used as the subject of a divisional application.

[0115] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.
