Description

[Technical field]

[0002] The utility model relates to the technical field of drinking water equipment, in particular to the technical field of a heat storage type heating drinking water system. [Background technology]

[0004] With the improvement of living standards, there are now various drinking water equipment and water purification equipment for people with different needs to choose from. Whether it is heating or cooling, whether it is fast heating or constant temperature, various functions and effects can be achieved through technical means.

[0005] The existing heating technology for drinking water equipment generally uses a heating element to heat drinking water and supply it to users. The common ways of heating drinking water are as follows: 1. Electric kettles heat directly inside the kettle, using a heating element as the bottom of the kettle to heat the water in the kettle; 2. Water dispensers heat continuously, and keep heating after being turned on, so that hot water can be supplied at any time; 3. Instant heating devices, which start heating when it is needed, can immediately respond to water needs and provide hot water.

[0006] The above methods of heating water have their own shortcomings and defects. For example, 1. Electric kettle heating generally requires manual water addition and uncontrollable temperature. Generally, it will stop heating automatically after boiling. The amount of water boiled each time is about 1~3L, and it needs to be replenished manually after use. 2. The temperature of the water dispenser that is continuously heated generally does not reach the boiling temperature. It can provide hot water at about 85~90℃. Because it is continuously heated, it is easy to produce thousands of boiling water, and there are safety hazards after scaling. 3. Instant heating is a heating drinking water device that has been favored by consumers and users recently. The required temperature can be set and heating will start when it is needed. Hot water can be supplied after heating. The disadvantage is that the flow rate of instant heating is small. Under the condition of 2200W, the maximum water flow rate is about 400ml / min. The most important thing is that the above methods of boiling water consume electricity when they are used, and if they are used during peak power consumption, the electricity bill is also a fee to pay. [Summary of the invention]

[0008] In view of the shortcomings and problems of the existing drinking water equipment, the utility model proposes a heat storage heating system. The most critical feature of the system is that it can utilize valley electricity to store energy and heat, and then use the stored heat to heat water during peak electricity consumption, which can not only reduce electricity bills, but also overcome the problem of small flow rate of instant heating equipment. Drinking water can be preheated in advance through a heat storage device under rated power, so the instantaneous heating flow rate can be greatly improved.

[0009] The utility model relates to a heat storage heating system, comprising a water inlet, a water pump, a heating body and a water outlet, and is characterized in that the system also comprises a phase change energy storage module, which comprises a shell, a heat exchanger, a phase change material and a heating body, wherein the phase change material is filled between the heat exchanger and the shell, the heating body is arranged on the heat exchanger so as to heat the phase change material, and the water pump draws water from the water inlet and passes through the phase change energy storage module to be connected to the water outlet.

[0010] The phase change energy storage module is provided with a flow channel connected to the heat exchanger, which is connected from the water inlet to the water outlet through the flow channel in the heat exchanger. Water pumped through the heat exchanger by a water pump is heated by heat exchange through the heat exchanger, and the water flow through the heat exchanger is controlled by controlling the flow of the water pump, so as to obtain the expected water outlet temperature.

[0011] The thermometer includes a module thermometer and a water outlet thermometer, wherein the module thermometer is arranged in the shell of the phase change energy storage module, and the water outlet thermometer is arranged at the water outlet.

[0012] The melting point of the phase change material is 100°C.

[0013] Furthermore, if it is necessary to expand the range of the phase change material that can be selected, the melting point range of the phase change material can be selected to be: 25°C~100°C.

[0014] If the melting point of the phase change material is lower than 100°C, a heating body needs to be added to the system for subsequent heating. The thermal storage heating system also includes a water outlet heating body, which is arranged between the phase change energy storage module and the water outlet.

[0015] A water inlet thermometer is provided at the water inlet end of the water outlet heating body, and a water outlet thermometer is provided at the water outlet end of the water outlet heating body.

[0016] The module thermometer, the water outlet thermometer and the water inlet thermometer are infrared thermometers, NTC thermometers or thermocouple thermometers.

[0017] The heat storage heating system involved in the utility model utilizes a phase change energy storage module containing phase change materials configured in the system to store heat during off-peak hours, and when water is needed, heating is performed using the stored heat energy in the phase change energy storage module. This not only rationally utilizes resources to achieve the effect of staggered electricity consumption, but also, with the matching instant heating body, realizes the purpose of supplying instant hot water at a large flow rate.

[Specific implementation method]

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Example 1: Please refer to the attached Figure 1 , which shows a specific implementation of a heat storage heating system involved in the utility model. As shown in the figure, the heat storage heating system includes a water inlet 10, a water pump 20, a heating body 30 and a water outlet 40, and is characterized in that the system also includes a phase change energy storage module 50, which includes a shell 51, a heat exchanger 52, a phase change material (not shown) and a heating body 30, wherein the phase change material is filled between the heat exchanger 52 and the shell 51, and the heating body 30 is arranged on the heat exchanger 52 based on its ability to heat the phase change material. In actual industrial production and manufacturing, the heating body 30 can be covered on the heat exchanger 52 or pasted on the shell 51, as long as the design can heat the phase change material to provide stored heat energy for the phase change material.

[0026] The water pump 20 draws water from the water inlet 10 and passes through the phase change energy storage module 50 to connect to the water outlet 40 .

[0027] The phase change energy storage module 50 is provided with a flow channel connected to the heat exchanger 52, which is connected from the water inlet 10 to the water outlet through the flow channel in the heat exchanger 52. A flow channel for water circulation is provided in the heat exchanger, and heat exchange is performed in the flow channel inside the heat exchanger, that is, the energy storage module 50 uses the stored heat to heat the water passing through the heat exchanger 52. At this time, the temperature of the water after passing through the heat exchanger 52 can be controlled by controlling the flow rate of the water pump.

[0028] The thermometer includes a module thermometer 11 and a water outlet thermometer 12 , wherein the module thermometer 11 is disposed in the housing 51 of the phase change energy storage module 50 , and the water outlet thermometer 12 is disposed at the water outlet 40 .

[0029] The module thermometer, the water outlet thermometer and the water inlet thermometer are infrared thermometers, NTC thermometers or thermocouple thermometers.

[0030] In this embodiment, the phase change material used preferably has a melting point of 100°C, so that the water passing through the phase change energy storage module 50 directly reaches the temperature of boiling water. During valley power, the whole machine does not work, but only uses the added power to store heat. The heating body 30 is heated by electricity, and the phase change material is heated to 100°C by the heating body 30, and then heat is stored. When water is needed, the whole machine starts working, and the raw water / purified water is transported to the phase change energy storage module through the water pump for heating. The outlet water temperature is controlled by controlling the flow rate of the water pump 20.

[0031] Example 2: Please refer to the attached Figure 2 , which shows a specific implementation of the second heat storage heating system. In this embodiment, the melting point range of the phase change material that can be selected can be selected from 25°C to 100°C. Any phase change material suitable for industrial mass production within the above melting point range can be considered for selection. Once a phase change material with a melting point temperature lower than 100°C is selected, it is necessary to add a water outlet heater 60 to the system. The water outlet heater is selected based on the heater set for instant heating. The water outlet heater itself can instantly provide hot water with a quick heating effect, but the flow rate is limited. Therefore, the incremental technology for instant heating is realized in conjunction with the phase change energy storage module 50. Under the condition of the original power limit, a large flow rate instant heating system can be provided. At the same time, the phase change energy storage module 50 uses valley electricity to store heat, and releases heat to heat water during peak electricity consumption, thereby reducing electricity costs.

[0032] The thermal storage heating system further includes a water outlet heater 60 , which is disposed between the phase change energy storage module 50 and the water outlet 40 .

[0033] A water inlet thermometer 13 is provided at the water inlet end of the water outlet heating body 60 , and a water outlet thermometer 12 is provided at the water outlet end of the water outlet heating body 60 .

[0034] During off-peak hours, the whole machine does not work, but only uses electricity to store heat. The heating body 30 heats the phase change material to 100°C and then stores heat. When water is needed, the whole machine starts working, and the raw water / clean water is pumped to the phase change energy storage module for heating. The outlet water temperature is controlled by controlling the flow of the water pump. However, when a large flow of hot water is needed, it cannot meet the demand, and then a water outlet heater is added to realize instant heating technology to achieve a large flow instant heating effect.

[0035] The heat storage heating system involved in the utility model utilizes a phase change energy storage module containing phase change materials configured in the system to store heat during off-peak hours, and when water is needed, heating is performed using the stored heat energy in the phase change energy storage module. This not only rationally utilizes resources to achieve the effect of staggered electricity consumption, but also, with the matching instant heating body, realizes the purpose of supplying instant hot water at a large flow rate.

[0036] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
