一种热泵热水器，包括水箱、热泵装置、两个电加热管和控制装置，控制装置包括控制盒以及设于控制盒内的控制板。控制板运行热泵模式，通过热泵装置加热水，此模式节能，水加热时间长，水温上升速度慢；控制板运行电加热模式，通过两个4.5KW的电加热管交替加热水，此模式水加热时间短，水温上升速度快，用于实现热水的快速与连续输出。A heat pump water heater comprises a water tank, a heat pump device, two electric heating tubes and a control device, wherein the control device comprises a control box and a control board arranged in the control box. The control board operates in a heat pump mode, heating water through the heat pump device, which is energy-saving, has a long water heating time and a slow water temperature rise rate; the control board operates in an electric heating mode, heating water alternately through two 4.5KW electric heating tubes, which has a short water heating time and a fast water temperature rise rate, and is used to achieve fast and continuous output of hot water.

因电加热管功率过大，会导致控制板上设置成控制电加热管的继电器发热量特别大，温度特别高，这样持续长期运行很容易造成控制板上设置成控制热泵装置的部件以及设置为控制电加热管的继电器因过热而损坏。Because the power of the electric heating tube is too large, the relay on the control board that is configured to control the electric heating tube will generate extremely large heat and the temperature will be extremely high. Such continuous and long-term operation can easily cause the components on the control board that are configured to control the heat pump device and the relay that is configured to control the electric heating tube to be damaged due to overheating.

该热泵热水器，第二控制装置150设于第一风道内，电加热模式下运行电加热装置10，电加热模式下还运行风机110，第一风束会对第二控制装置150进行风冷散热，使第二控制装置150的温度降低，这样第二控制装置150不容易过热损坏，故此方案提供的热泵热水器更不容易出现故障。In the heat pump water heater, the second control device 150 is arranged in the first air duct. The electric heating device 10 is operated in the electric heating mode. The fan 110 is also operated in the electric heating mode. The first wind beam will perform air cooling and heat dissipation on the second control device 150 to reduce the temperature of the second control device 150. In this way, the second control device 150 is not easily overheated and damaged. Therefore, the heat pump water heater provided by this solution is less prone to failure.

在一些示例中，控制部分还包括第一控制装置140，第一控制装置140与第二控制装置150相间隔，第一控制装置140设置成对热泵装置进行控制，第一控制装置140和第二控制装置150中的至少之一设置成对风机110进行控制。In some examples, the control part also includes a first control device 140, which is separated from a second control device 150, and the first control device 140 is configured to control the heat pump device, and at least one of the first control device 140 and the second control device 150 is configured to control the fan 110.

由于第一控制装置140和第二控制装置15相间隔，这样电加热模式下，第二控制装置150产生的热量更不容易传递至第一控制装置140上，因此第一控制装置140的温度更低，不会出现过热损坏的问题，故此方案提供的热泵热水器更不容易出现故障。Since the first control device 140 and the second control device 15 are spaced apart, in the electric heating mode, the heat generated by the second control device 150 is less likely to be transferred to the first control device 140. Therefore, the temperature of the first control device 140 is lower and there will be no problem of overheating damage. Therefore, the heat pump water heater provided by this solution is less prone to failure.

如图10所示，风机110正向转动，外界空气自第一过风口121依次经第一风道、换热器131、第二风道后，自第二过风口122吹向外界，此过程第一风束会对第二控制装置150进行风冷散热，使第二控制装置150的温度降低；如图11所示，风机110反向转动，外界空气自第二过风口122依次经第二风道、换热器131、第一风道后，自第一过风口121吹向外界，此过程第一风束会对第二控制装置150进行风冷散热，使第二控制装置150的温度降低。其中，如图4至图7所示，第二控制装置150的下部设有过线套环159，机头组件100设于水箱组件200的上部，电加热装置210向上引线、并穿过过线套换159 而接入第二控制装置150内。As shown in FIG10, the fan 110 rotates forward, and the outside air passes through the first air duct, the heat exchanger 131, and the second air duct from the first air outlet 121 in sequence, and then blows to the outside from the second air outlet 122. In this process, the first wind beam will cool the second control device 150, so that the temperature of the second control device 150 is reduced; as shown in FIG11, the fan 110 rotates reversely, and the outside air passes through the second air duct, the heat exchanger 131, and the first air duct from the second air outlet 122 in sequence, and then blows to the outside from the first air outlet 121. In this process, the first wind beam will cool the second control device 150, so that the temperature of the second control device 150 is reduced. As shown in FIG4 to FIG7, a wire collar 159 is provided at the lower part of the second control device 150, the head assembly 100 is provided at the upper part of the water tank assembly 200, and the electric heating device 210 leads upward and passes through the wire collar 159.

本方案防火盒151为钣金件，省去了防火盒151内部的绝缘盒152，由于钣金件的导热性能较好，故第一风束对控制板153的散热效果比较好。In this solution, the fireproof box 151 is a sheet metal part, and the insulating box 152 inside the fireproof box 151 is omitted. Since the sheet metal part has good thermal conductivity, the first air beam has a better heat dissipation effect on the control board 153.

The second wind beam blows out of the fireproof box 151 from the third air outlet and takes away the heat of the control board 153, then passes through the heat exchanger 131 with the first wind beam, and blows to the outside from the second air outlet 122. The fan 110 is operated in the reverse direction. Under the action of the first wind beam, the interior of the fireproof box 151 forms a second wind beam flowing from the third air outlet through the wind compartment to the fourth air outlet. The second wind beam blows out of the fireproof box 151 from the fourth air outlet and takes away the heat of the control board 153, then blows to the outside from the first air outlet 121 with the first wind beam.

The heat generated at the wiring terminal 157 is relatively large, and the wind-passing zone can improve the heat dissipation effect of the wiring terminal 157. It can be that the insulating bracket 154 includes four mounting seats, and the four mounting seats fix the four corner positions of the control board, and the wind-passing zone is formed between adjacent mounting seats.
