Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of water dispensers, in particular to a water dispenser and a heating and heat storage module thereof. BACKGROUND
[0002] A water dispenser is a daily drinking device widely used in families, offices and public places, which mainly functions to heat, cool or directly dispense water to meet the drinking water needs of users in different scenarios. A traditional storage type water dispenser stores a certain amount of water in a water tank and repeatedly heats it to maintain the water temperature.
[0003] The water dispenser in the prior art usually uses an electric heating tube or a heating cylinder to heat and repeatedly heat the water in the water tank, which meets the user's hot water demand, but also has many problems. On the one hand, repeatedly heating the water to boiling point will gradually increase the content of nitrite, which may have adverse effects on human health if consumed for a long time; on the other hand, continuous heating consumes a large amount of electricity, which not only increases the cost of household electricity consumption, but also contradicts the current demand for energy saving and environmental protection. CONTENT OF THE INVENTION
[0004] Therefore, the present application provides a water dispenser and a heating and heat storage module thereof to solve the health risks and high energy consumption caused by repeated heating of water in the prior art.
[0005] In order to achieve the above-mentioned purpose, the present application provides the following technical solutions:
[0006] A heating and heat storage module suitable for a water dispenser, comprising a heat storage member and a heating member connected to the heat storage member and used to heat the heat storage member at intervals, the heat storage member comprising a containing cavity for filling a phase change layer, the heat storage member being connected with a hot water pipe located in the containing cavity and embedded in the phase change layer, one end of the hot water pipe penetrating out of the heat storage member and being connected to a water heating part of the water dispenser, the other end of the hot water pipe penetrating out of the heat storage member and being connected to a hot water drain pipe of the water dispenser.
[0007] Optionally, the heat storage member comprises a box body and a box cover connected to the box body, the box body and the box cover enclosing the containing cavity, the hot water pipe comprising a middle section, a water inlet section integrally formed at one end of the middle section and connected to the water heating part of the water dispenser, and a water outlet section integrally formed at the other end of the middle section and connected to the hot water drain pipe of the water dispenser, the box cover being provided with a water inlet hole matched with the water inlet section, the box cover being provided with a water outlet hole matched with the water outlet section, and the middle section being coiled in the phase change layer.
[0008] The heating member is two, and the two heating members are respectively connected to the box cover and the side of the box body away from the box cover.
[0009] Optionally, the heating element is a PTC heating plate, and the heating power of the PTC heating plate is 250 W.
[0010] Optionally, the phase transition point of the phase transition layer is 60℃.
[0011] Optionally, the length of the box body is 384 mm, the width is 164 mm, the height is 21 mm, the volume of the phase transition layer is 1.1 L, the wall thickness of the box body and the thickness of the box cover are both 0.5 mm, and the box body, the box cover and the hot water pipe are all made of stainless steel, and the size of the hot water pipe is Ф5*0.3 mm.
[0012] The application also discloses a water dispenser comprising the heating and heat storage module suitable for the water dispenser.
[0013] Compared with the prior art, the application has at least the following beneficial effects:
[0014] The water heating part of the water dispenser heats water, and the heated water flows into the hot water pipe embedded in the phase transition layer of the heat storage element. The phase transition layer has high heat storage capacity, which can absorb the heat in the hot water pipe and convert it into latent heat of phase transition for heat storage, thereby reducing heat loss. On the other hand, the heating element will heat the heat storage element at intervals, further maintaining the heat storage state of the phase transition layer and keeping it at a constant temperature for a long time. In this way, the water heating part only needs to heat the water once, and the hot water pipe embedded in the phase transition layer can keep the water temperature stable. The phase transition layer can effectively prolong the water temperature maintaining time. Even in a long time interval, the heating element only needs to periodically supplement the heat storage element with heat, avoiding the repeated heating phenomenon of the traditional water dispenser when the water temperature drops, thereby significantly reducing energy consumption.

[0024] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.
[0025] In the description of the present application: unless otherwise specified, the meaning of "a plurality of" is two or more. The terms "first", "second", "third" and the like in the present application are intended to distinguish the objects referred to, and do not have special meanings in the technical connotation aspect (for example, should not be understood as emphasizing importance or order, etc.). The expressions "include", "contain", "have" and the like also mean "not limited to" (certain units, components, materials, steps, etc.).
[0026] Reference Figures 1-6 The present application discloses a heating and heat storage module for a water dispenser, which comprises a heat storage part 1 and a heating part 2 connected to the heat storage part 1 and used for heating the heat storage part 1 at intervals, the heat storage part 1 comprises an accommodating cavity 111 for filling a phase change layer 13, the heat storage part 1 is connected with a hot water pipe 3 located in the accommodating cavity 111 and embedded in the phase change layer 13, one end of the hot water pipe 3 penetrates out of the heat storage part 1 and is connected to a water heating part of the water dispenser, and the other end of the hot water pipe 3 penetrates out of the heat storage part 1 and is connected to a hot water outlet pipe of the water dispenser.
[0027] The water heating part of the water dispenser heats the water, and the heated water flows into the hot water pipe 3 embedded in the phase change layer 13 of the heat storage member 1. The phase change layer 13 has high heat storage capacity, which can absorb the heat in the hot water pipe 3 and convert it into latent heat of phase change for heat storage, thereby reducing heat loss. On the other hand, the heating member 2 will heat the heat storage member 1 at intervals, further maintaining the heat storage state of the phase change layer 13, so that it maintains a constant temperature for a long time. In this way, the water heating part only needs to heat the water once, and the hot water pipe 3 embedded in the phase change layer 13 can maintain the water temperature stable. The phase change layer 13 can effectively prolong the water temperature retention time, and even in a long time interval, the heating member 2 only needs to periodically supplement the heat storage member 1 with heat, avoiding the phenomenon of repeated heating after the water temperature drops in the traditional water dispenser, thereby significantly reducing energy consumption.
[0028] It should be noted that the water heating part can be a heating cylinder, an electric heating pipe or the like of the water dispenser, which functions to quickly heat the water to the target temperature and then deliver it to the hot water pipe 3.
[0029] In some embodiments, the water dispenser can be directly connected to the hot water pipe 3, and the heat storage member 1 is intermittently heated by the heating member 2, while the phase change layer 13 of the heat storage member 1 is used for heat storage and temperature retention. When the water flows through the hot water pipe 3, the heat storage function of the phase change layer 13 can quickly transfer heat to the water, so that the water is heated to a suitable drinking temperature.
[0030] The heat storage member 1 includes a box body 11 and a box cover 12 connected to the box body 11, and the box body 11 and the box cover 12 form a containing cavity 111. The hot water pipe 3 includes a middle section 31, a water inlet section 32 integrally formed at one end of the middle section 31 and connected to the water heating part of the water dispenser, and a water outlet section 33 integrally formed at the other end of the middle section 31 and connected to the hot water outlet pipe of the water dispenser. The box cover 12 is provided with a water inlet hole 121 matched with the water inlet section 32, and the box cover 12 is provided with a water outlet hole 122 matched with the water outlet section 33. The middle section 31 is coiled in the phase change layer 13.
[0031] The heating member 2 is two, and the two heating members 2 are respectively connected to the box cover 12 and the side of the box body 11 away from the box cover 12.
[0032] The box cover 12 can be detached from the box body 11 to replace or maintain the phase change layer 13 and the hot water pipe 3 in the containing cavity 111. The middle section 31 of the hot water pipe 3 is spirally wound in the phase change layer 13, which increases the length of the middle section 31 embedded in the phase change layer 13 and the contact area with the phase change layer 13, thereby improving the heat transfer efficiency. The phase change layer 13 can quickly absorb the heat of the water in the hot water pipe 3 for heat storage and release the heat back to the water in the hot water pipe 3 when needed, keeping the water temperature constant. At the same time, the two heating elements 2 are located on opposite sides of the heat storage element 1 to uniformly heat the phase change layer 13, making the temperature distribution in the phase change layer 13 more stable and avoiding the problems of local overheating or insufficient temperature.
[0033] In some embodiments, the box cover 12 can be connected to the box body 11 by a buckle or a hinge or the like.
[0034] The heating element 2 is a PTC heating plate, and the heating power of the PTC heating plate is 250W.
[0035] The PTC heating plate is a heating element based on the prior art, which has the characteristics of self-limiting temperature and high safety. The heating power of the PTC heating plate is 250W, which can quickly heat up during operation and significantly increase the resistance after reaching the set temperature, thereby automatically reducing the power output and avoiding overheating. Through this characteristic, the PTC heating plate can efficiently and stably heat the phase change layer 13 of the heat storage element 1, while avoiding the problems of dry burning or excessive energy consumption that may be caused by long-time work of traditional electric heating pipes.
[0036] In some embodiments, the PTC heating plate can be controlled by a controller or the like to control the heating time.
[0037] The phase change point of the phase change layer 13 is 60℃.
[0038] In some embodiments, after the phase change is complete, the heat stored by the phase change layer 13 is sufficient to heat 1L of pure water from 25℃ to 60℃.
[0039] The phase change layer 13 can be made of inorganic phase change materials, organic phase change materials or composite phase change materials.
[0040] The length of the box body 11 is 384mm, the width is 164mm, and the height is 21mm. The volume of the phase change layer 13 is 1.1L. The wall thickness of the box body 11 and the thickness of the box cover 12 are both 0.5mm. The box body 11, the box cover 12 and the hot water pipe 3 are all made of stainless steel, and the size of the hot water pipe 3 is Ф5*0.3mm.
[0041] In some embodiments, a copper wire can be wound around the outer wall of the hot water pipe 3 to increase the heat conduction efficiency.
[0042] The application also discloses a water dispenser comprising the heating and heat storage module suitable for the water dispenser.
[0043] The technical features of the above embodiments can be combined in any manner (as long as the combination of the technical features does not exist contradiction), for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described; these embodiments which are not explicitly written should also be considered as the scope of the present application.

It should be understood that, based on the technical concept of the application, some conventional adjustments or further innovations can be made to the specific embodiments; as long as the technical concept of the application is not deviated, the technical solutions obtained by the conventional adjustments or further innovations also fall within the protection scope of the claims of the application.
