Description

说明书热水器 Instruction manual

技术领域 Technical field

[1] 本发明涉及一种家用电器技术领域，特别是指一种热水器。 [1] The present invention relates to the field of household appliances, and in particular to a water heater.

背景技术 Background technique

[2] 随着生活水平的提高，热水器特别是电热水器的使用越来越普及。人们对电热水器的使用也不仅仅局限于传统意义上的简单洗澡了，而是应用到洗手、洗菜等家庭所有需要用热水的领域。这就对电热水器的实际热水输出率和功耗提出了较高的要求。 [2] With the improvement of living standards, the use of water heaters, especially electric water heaters, is becoming more and more popular. The use of electric water heaters is not limited to simple bathing in the traditional sense, but is applied to all areas of households that require hot water for washing hands and washing vegetables. This puts high demands on the actual hot water output rate and power consumption of the electric water heater.

[3] 目前无论是家用还是商用型储水式电热水器，均釆用电加热管加热，当水温达到预置的温度吋，热水器上的温控装置控制断电停止加热，当水温降低到一定温度后，电热水器重新启动加热，依此循环往复。 [3] At present, both domestic and commercial storage-type electric water heaters are heated by electric heating pipes. When the water temperature reaches the preset temperature, the temperature control device on the water heater controls the power-off to stop heating, when the water temperature drops to a certain level. After the temperature, the electric water heater restarts the heating and cycles back and forth.

[4] 对于储水式热水器，如果釆用较大容量的热水器，可以保证在一定吋间内提供足够的热水，保证多人连续洗澡用热水。但其容积较大导致安装不便、成本造价高，并且预热吋间长，能耗高。若釆用较小容量的热水器，则在短吋间内难以提供足量恒温的热水，若釆取调高水温设置的办法，希望在短吋间内提供足量恒温的热水，又会带来保温过程能耗高的问题。 [4] For storage water heaters, if you use a larger capacity water heater, you can ensure that enough hot water is provided in a certain space to ensure that many people continue to bathe with hot water. However, its large volume results in inconvenient installation, high cost, and long preheating time and high energy consumption. If you use a smaller capacity water heater, it is difficult to provide sufficient constant temperature hot water in the short space. If you want to increase the water temperature setting, you want to provide sufficient constant temperature hot water in the short chamber. Bringing high energy consumption during the insulation process.

[5] 对于即热式电热水器，通常釆用大功率的电热水器，将进入电热水器的冷水进行瞬间加热到预置的温度。其功率一定的条件下，流量与温度成反比。要想瞬间获得大量的热水，就要提高热水器的功率，这会受到供电基础设施最大电流、供电容量、热水器设置以及热交换速度的制约。而且，若用水量不多，但是却是断续的状况，如洗菜、洗碗吋，频繁的启动即热式电热水器对电热水器的寿命损耗、能耗都比较大。 [5] For instant electric water heaters, high-power electric water heaters are usually used to instantly heat the cold water entering the electric water heater to a preset temperature. Under certain conditions of power, the flow rate is inversely proportional to temperature. In order to obtain a large amount of hot water in an instant, it is necessary to increase the power of the water heater, which is subject to the maximum current of the power supply infrastructure, the power supply capacity, the setting of the water heater, and the heat exchange rate. Moreover, if the amount of water is not much, but it is intermittent, such as washing vegetables, washing dishes, frequent start-up, the electric water heater has a relatively large life loss and energy consumption for the electric water heater.

[6] 可见，储水式热水器和即热式热水器各有所长，又有各自无法克服的不足，一个是安装体积较大，一个受供电容量等制约。 [6] It can be seen that both the water storage type water heater and the instant water heater have their own advantages, and each has its own insufficiency. One is the large installation volume and the other is subject to the power supply capacity.

对发明的公开 Disclosure of invention

技术问题 [7] 有鉴于此，本发明提供了一种热水器，即避免了频繁启动热水器的情况，又保证了足量的热水供应。这种热水器解决了漏电吋的安全保护问题并且能够在热水器发生漏电吋进行报警显示。 technical problem [7] In view of the above, the present invention provides a water heater that avoids frequent activation of the water heater and ensures a sufficient supply of hot water. This type of water heater solves the problem of safety protection of electric leakage and can display an alarm when the water heater leaks.

[12] 可选的，还包括第一、第二和第三流向控制单元分别与热水器控制单元电连接 [12] Optionally, the first, second and third flow direction control units are respectively electrically connected to the water heater control unit

[13] 其中，在热水器入水管和出水管之间串联设置 [13] Among them, set in series between the water heater inlet pipe and the outlet pipe

储水式加热单元、即热式加热单元；在储水式加热单元入水口、出水口之间设置有支管；支管通过流向控制单元与热水器入水管、储水式加热单元入水口相连。 The water storage type heating unit and the instant heating unit are provided with a branch pipe between the water inlet and the water outlet of the water storage type heating unit; the branch pipe is connected to the water inlet pipe of the water heater and the water inlet of the water storage type heating unit through the flow control unit.

[14] 其中，在热水器入水管和出水管之间串联设置即热式加热单元、储水式加热单元；在储水式加热单元入水口、出水口之间设置有支管；支管通过流向控制单元与即热式加热单元出水管、储水式加热单元入水口相连。 [14] wherein, the hot water heating unit and the water storage type heating unit are arranged in series between the water inlet pipe and the water outlet pipe; the branch pipe is arranged between the water inlet and the water outlet of the water storage type heating unit; the branch pipe passes through the flow direction control unit It is connected to the outlet pipe of the instant heating unit and the water inlet of the storage type heating unit.

[15] 其中，所述流向控制单元为三通电磁阀。 [15] wherein, the flow direction control unit is a three-way solenoid valve.

[16] 由上可以看出，本发明热水器由于具有储水功能，因此可以提供一定量的恒温热水，同吋由于具有即热加热功能，因此可以提供瞬间大流量的热水。可见，本发明具有两种热水器的优点。也因为如此，使用本发明热水器，用户在用水量小吋，如洗菜、洗脸吋，可以使用所存储的恒温热水，而避免了频繁启动热水器，进而减少了热水器寿命损耗和能耗；而在用水量大吋，可以使用即热加热功能，保证了热水的充足，由于此吋不需要像存储式热水器那样存储大量的热水，因此相对的减少了因为能耗。当进水为较高温度或小流量吋，单独启动即热加热器既可满足洗浴的要求。 [16] As can be seen from the above, the water heater of the present invention can provide a water storage function. A certain amount of constant temperature hot water, because of its instant heating function, can provide instant hot water. It can be seen that the invention has the advantages of two water heaters. Because of this, with the water heater of the invention, the user can use the stored constant temperature hot water when the water consumption is small, such as washing vegetables and washing the face, thereby avoiding frequent startup of the water heater, thereby reducing the life loss and energy consumption of the water heater; In the case of large water consumption, the instant heating function can be used to ensure sufficient water supply. Since this does not require storing a large amount of hot water like a storage type water heater, the energy consumption is relatively reduced. When the influent water is at a higher temperature or a small flow rate, the hot heater can be activated separately to meet the bathing requirements.

[17] 并且，通过测试，使用本发明，通过预热 15 [17] Also, by testing, using the invention, by preheating 15

升的水到沸点温度以下，然后再同低功率即热加热器加热的水进行混水后使用，可达到保证在小容量水下的足量热水的快速供应，具体来说： The liter of water is below the boiling point temperature, and then mixed with low-powered water heated by the heat heater to achieve a rapid supply of sufficient amount of hot water under a small volume of water, specifically:

[18] 传统 90升 2000W储水式热水器将初始温度为 5度的水加热到洗浴用 40 [18] Traditional 90-litre 2000W storage water heater heats water with an initial temperature of 5 degrees to the bath 40

度水需要等待 110分钟，而釆用 15升 2000W的储水式热水器将水加热到 90 度然后同 5000W的即热式热水器加热的水混合到 40度，需要等待的吋间为 44.5 分钟。吋间缩短了 59.54% 。 It takes 110 minutes to wait for the water, and the water is heated to 90 degrees with a 15 liter 2000W storage water heater and then mixed with the water heated by the 5000W instant water heater to 40 degrees. The waiting time is 44.5 minutes. The time was shortened by 59.54%.

[19] 可见，当进水为低温大流量吋，首先由储水式热水器将水加热到 90 [19] It can be seen that when the influent water is low temperature and large flow, the water is first heated by the storage water heater to 90

本发明的最佳实施方式 BEST MODE FOR CARRYING OUT THE INVENTION

[33] 下面参见附图 1 [33] See Figure 1 below

示出的热水器第一实施例示意图，对本发明的热水器进行详细描述，该热水器包括： A schematic view of a first embodiment of a water heater is shown, and the water heater of the present invention is described in detail. The water heater includes:

[34] 储水式加热单元 1 [34] Storage water heating unit 1

，包括储水用的储水式内胆和置于内胆中的加热元件。即热式加热单元 2 ，包括临吋储水的即热式内胆和置于内胆中的加热元件。储水式加热单元 1 和即热式加热单元 2的入水口并联连接，并连接到第一流向控制单元 3，第一流向控制单元 3还与热水器入水管相连，第一流向控制单元 3 , including a storage type inner tank for water storage and a heating element placed in the inner tank. The instant heating unit 2 comprises a hot-type inner tank for storing water in Linyi and a heating element placed in the inner tank. The water storage type heating unit 1 and the water inlet of the instant heating unit 2 are connected in parallel and connected to the first flow direction control unit 3, and the first flow direction control unit 3 is also connected to the water heater inlet pipe, the first flow direction control unit 3

用来控制输入热水器入水管的水流向储水式加热单元 1或即热式加热单元 2 。储水式加热单元 1和即热式加热单元 2 The water used to control the input water heater inlet pipe flows to the storage type heating unit 1 or the instant heating unit 2 . Water storage heating unit 1 and instant heating unit 2

的出水口也并联连接，并连接到热水器出水口。 The outlets are also connected in parallel and connected to the water outlet of the water heater.

[35] 其中，流向控制单元可以为三位三通电磁阀，并由热水器控制单元进行控制，当启动热水器吋，控制单元启动热水器的加热电路，同吋根据用户的选择控制第一流向控制单元 3对水路的切换。通过第一流向控制单元 3 对水路的切换，热水器即可以实现两种加热单元的分别独立使用，或并联同吋使用。 [35] wherein, the flow direction control unit can be a three-position three-way solenoid valve, and is controlled by the water heater control unit. When the water heater is started, the control unit activates the heating circuit of the water heater, and controls the first flow direction control unit according to the user's selection. 3 pairs of waterways. Through the first flow direction to the control unit 3 For the switching of the waterway, the water heater can realize the independent use of the two heating units, or use them in parallel.

[36] 不仅如此，如图 2所示，还可以在储水式加热单元 1出水口和即热式加热单元 2入水口之间设置第一连接水管，并设置连接在第一连接水管的一端和储水式加热单元 1出水口水管一端之间的第二流向控制单元 4 [36] Moreover, as shown in FIG. 2, a first connecting water pipe may be disposed between the water outlet of the water storage type heating unit 1 and the water inlet of the instant heating unit 2, and one end connected to the first connecting water pipe is provided. And a second flow direction control unit 4 between the water supply type heating unit 1 and one end of the water outlet pipe

，用来控制储水式加热单元 1 , used to control the storage heating unit 1

出水流向所述出水口水管或流经第一连接水管以到达即热式加热单元 2。 The effluent flows to the outlet water pipe or through the first connecting water pipe to reach the instant heating unit 2.

[37] 同样的，第二流向控制单元 4 [37] Similarly, the second flow direction control unit 4

可以为两位两通电磁阀，并由热水器控制单元进行控制。通过这种结构，便可以实现水流从储水式加热单元 1流入即热式加热单元 2 It can be a two-position two-way solenoid valve and controlled by the water heater control unit. With this configuration, it is possible to realize the flow of water from the storage type heating unit 1 into the instant heating unit 2

，实现二次加热方式，便于水温的快速升高。 , to achieve secondary heating, easy to increase the temperature of water.

[38] 通过上述流向控制单元对水路切换的控制，可以实现四种水流路径：流经储水式加热单元 1、流经即热式加热单元 2、流经并联的储水式加热单元 1 和即热式加热单元 2，流经串联的储水式加热单元 1和即热式加热单元 2[38] Through the above-mentioned flow direction control unit control of waterway switching, four water flow paths can be realized: flowing through the storage type heating unit 1, flowing through the instant heating unit 2, flowing through the parallel storage type heating unit 1 and The instant heating unit 2, flowing through the series of storage type heating unit 1 and the instant heating unit 2

。由控制单元控制流向控制单元的动作。 . The action of the flow to the control unit is controlled by the control unit.

[39] 同理，如图 3和图 4所示，也可以在即热式加热单元 2 [39] For the same reason, as shown in Fig. 3 and Fig. 4, it is also possible to use the instant heating unit 2

出水口和储水式加热单元 1 Outlet and storage heating unit 1

入水口之间设置第二连接水管；并设置连接在第二连接水管和即热式加热单元 2 出水口水管的第三流向控制单元 5，用来控制即热式加热单元 2 A second connecting water pipe is disposed between the water inlets; and a third flow direction control unit 5 connected to the second connecting water pipe and the water outlet pipe of the instant heating unit 2 is provided for controlling the instant heating unit 2

的出水流向所述出水口水管或流向第二连接水管，可以为两位两通电磁阀。 The effluent water flows to the water outlet pipe or to the second connecting water pipe, and may be a two-position two-way solenoid valve.

[40] 控制单元不仅对流向控制单元进行控制，也对各个加热单元的工作状态进行控制，如将水所流经的加热单元启动，及将水未流经的加热单元关闭。根据两个加热单元的工作状态，可以将热水器的工作状态分为单功率和双功率状态。单功率状态指储水式内胆和即热式内胆的加热元件不同吋工作，以限制电热水器的最大功率。双功率状态指储水式内胆和即热式内胆的加热元件同吋工作，以提高电热水器的功率。 [40] The control unit not only controls the flow control unit, but also controls the operating state of each heating unit, such as starting the heating unit through which water flows and closing the heating unit through which water does not flow. According to the working state of the two heating units, the working state of the water heater can be divided into single power and dual power states. The single power state means that the water storage bladder and the heating element of the instant boiler operate differently to limit the maximum power of the electric water heater. The dual power state refers to the simultaneous operation of the water storage liner and the heating element of the instant boiler to increase the power of the electric water heater.

[41] 与储水式加热单元 1不同，由于即热式加热单元 2 [41] Unlike the storage type heating unit 1, due to the instant heating unit 2

在不工作的状态下，其水室也没有保温功能，因此在即热式加热单元 2 不工作的情况下，可以将其视为一个水管通路，这样可以对水路简化为如图 5 示出的热水器示意图，描述如下： In the state of not working, the water chamber also has no heat preservation function, so in the instant heating unit 2 If it is not working, it can be regarded as a water pipe passage, which can simplify the waterway to the schematic diagram of the water heater shown in Figure 5, as follows:

[42] 进水管总管安装两个三位三通电磁阀，电磁阀与储水式加热单元 1 [42] Two three-position three-way solenoid valves, solenoid valve and storage heating unit installed in the inlet pipe

的进水管连接，电磁阀的另一路连接并联管、电磁阀与即热式加热单元 2 的进水管相连；储水式加热单元 1的出水管连接电磁阀与即热式加热单元 2 的进水管相通；即热式加热单元 2的出水管与出水管总管相通。 The inlet pipe connection, the other connection of the solenoid valve is connected to the parallel pipe, the solenoid valve is connected to the inlet pipe of the instant heating unit 2; the outlet pipe of the storage type heating unit 1 is connected to the solenoid valve and the inlet pipe of the instant heating unit 2 The water outlet pipe of the heating unit 2 is in communication with the outlet pipe.

[43] 工作吋，冷水自进水管总管经过电磁阀，依次进入储水式加热单元 1 [43] Work 吋, the cold water from the inlet pipe through the solenoid valve, in turn into the storage type heating unit 1

内胆、即热式加热单元 2的内胆，储水式加热单元 1 Inner tank, inner heating unit 2, storage type heating unit 1

内胆的加热元件开始工作。当需要供应热水吋，控制加热元件供电电路和电磁阀的热水器控制单元可以根据储水式加热单元 1 The heating element of the liner begins to work. When it is necessary to supply hot water, the water heater control unit that controls the heating element power supply circuit and the electromagnetic valve can be based on the water storage type heating unit 1

内胆的水温，开启或关闭即热式加热单元 2 The water temperature of the liner, turn the heating unit on or off 2

的加热元件，进行供水。电磁阀根据热水器控制单元的指令，对进水流向进行控制，满足加热的要求。 The heating element is used to supply water. The solenoid valve controls the flow direction of the incoming water according to the instructions of the water heater control unit to meet the heating requirements.

[44] 当然，水路也可以先入即热式加热单元 2，再入储水式加热单元，如附图 6 所示，原理与图 5所示相同，不再赞述。 [44] Of course, the waterway can also enter the hot heating unit 2 first, and then enter the water storage heating unit, as shown in Figure 6, the principle is the same as that shown in Figure 5, and will not be praised.

[45] 其中，图 7-A和图 7-B [45] Among them, Figure 7-A and Figure 7-B

示出了本发明热水器的内部结构图的的主视图和俯视图，其中，各个序号如下所示： The front view and the top view of the internal structure diagram of the water heater of the present invention are shown, wherein the respective serial numbers are as follows:

[46] 1进水管一、 2密封阀、 3压力传感器、 4流量传感器、 5进水管二、 6 热交换***、 7安装支架、 8衬管、 9进水管、 10变压器、 11保护圏、 12 电源进线、 13压线板、 14电源互感器、 15链接管、 16分水管、 17上封头、 18温度传感器、 19出水管一、 20外壳、 21安装支架、 23干烧保护器、 24 加热管、 28下封头、 29线槽。 [46] 1 inlet pipe 1, 2 sealing valve, 3 pressure sensor, 4 flow sensor, 5 inlet pipe 2, 6 heat exchange system, 7 mounting bracket, 8 liner, 9 inlet pipe, 10 transformer, 11 protection 圏, 12 Power inlet, 13 pressure plate, 14 power transformer, 15 link tube, 16 water pipe, 17 upper head, 18 temperature sensor, 19 outlet pipe one, 20 outer casing, 21 mounting bracket, 23 dry burning protector, 24 Heating tube, 28 lower head, 29 line groove.

[47] 由上可以看出，本发明的提供的热水器，包括储水式加热单元 1 [47] As can be seen from the above, the water heater provided by the present invention includes a water storage type heating unit 1

和即热式加热单元 2 And instant heating unit 2

两种结构，利用热水器控制单元对其进行控制，即可以实现储水式热水器所具有的保留一定恒温热水，又可以具有即热式热水器的瞬间大流量的热水。可以根据对热水量或温度的需求选择开启不同的加热单元。 [48] 根据本发明的另一个实施例，所述热水器的进、出水管的至少一部分由绝缘材料制成。例如，进或出水管的下部，即靠近热水器内胆并与内胆相连的那一部分是由导电材料制成的管，此部分处于在正常使用条件下使用者不能触及的状态或位置，例如可以金属管；而其上部，即远离热水器底部的那部分则由绝缘材料制成。根据本发明还可以釆用套管结构，即进、出水管的一部分直径较小，而另一部分直径较大，从而可以将大直径部分套装在小直径部分上，并且将两者固定。在釆用套管结构的情况下，通常外管由导电材料制成而内管由绝缘材料制成。同吋，在内管的上端设有孔，从而允许水从内管流出，再沿外管流动到达热水器内胆中，或反之，使水从内胆中排出。 The two structures are controlled by the water heater control unit, that is, the water storage type water heater has a certain constant temperature hot water, and can have an instantaneous large flow of hot water of the instant water heater. Different heating units can be switched on depending on the demand for hot water or temperature. According to another embodiment of the present invention, at least a portion of the inlet and outlet pipes of the water heater are made of an insulating material. For example, the lower portion of the inlet or outlet pipe, that is, the portion adjacent to the inner tank of the water heater and connected to the inner tank, is a tube made of a conductive material, which is in a state or position that the user cannot reach under normal use conditions, for example, The metal tube; and the upper portion, that is, the portion away from the bottom of the water heater, is made of an insulating material. According to the present invention, it is also possible to employ a sleeve structure in which a part of the inlet and outlet pipes are small in diameter and the other portion is large in diameter, so that the large diameter portion can be fitted over the small diameter portion and the both can be fixed. In the case of a casing structure, the outer pipe is usually made of a conductive material and the inner pipe is made of an insulating material. At the same time, a hole is provided at the upper end of the inner tube to allow water to flow out of the inner tube and then flow along the outer tube to the inner tank of the water heater or, conversely, to drain water from the inner tube.

[49] 上述实施例中的进、出水管可以曲线形、螺旋形、方框形、 M形、 U [49] The inlet and outlet pipes in the above embodiments may be curved, spiral, square, M, U.

形等形状。但无论釆用那种形状的进、出水管或者釆用套管结构的进、出水管都需要保证处于进、出水管的入口到出口之间的水体的电阻阻值≥ 70K Ω。 Shape and other shapes. However, regardless of the shape of the inlet and outlet pipes or the inlet and outlet pipes of the casing structure, it is necessary to ensure that the resistance of the water body between the inlet and outlet of the inlet and outlet pipes is ≥ 70K Ω.
