Embodiment 1

[0061] see Picture 1-1 A range hood 1 with a centrifugal fan 1-1.2 structure is used, and a heat exchanger 1-1.1 is installed at the air inlet of the fan, and the heat exchanger 1-1.1 is an evaporator of an air energy water heater.

[0062] The heat exchanger 1-1.1 is located at the suction port of the centrifugal fan 1-1.2. The heat exchanger 1-1.1 is arranged vertically, that is, the height of the heat exchanger is in the up-down direction of the range hood 1, and the width is in the left-right direction. The centrifugal fan 1-1.2 adopts a side suction structure, and the suction port of the centrifugal fan 1-2.2 faces the heat exchanger 1-1.1 on the left. The oily fume first passes through the left side of the evaporator 1-1.1, passes through the right side of the evaporator 1-1.1, then goes to the centrifugal fan 1-1.2, and finally is discharged from the air outlet 1-1.3. In this process, the waste heat of oil fume is transferred to the evaporator 1-1.1, so as to realize ...

Embodiment 2

[0068] see Figure 1-2 , and the difference from Example 1 is that the width of the heat exchanger 1-1.1 is in the front and back direction of the range hood 1, and is arranged in front of the axial flow fan 1-1.2, and the axial flow fan 1-1.2 is arranged in the heat exchanger 1-1.2 1.1 behind. The air suction port of the axial fan 1-1.2 faces the heat exchanger 1-1.1.

[0069] In the above description, viewed from the front of the range hood, the horizontal direction of the range hood is the left and right direction (that is, the length direction of the evaporator), and the vertical direction is the height direction of the range hood.

Embodiment 3

[0071] see Figure 2-1 and Figure 2-2 , the difference from Example 1 is that the heat exchanger 1-2.1 is located at the air outlet position of the centrifugal fan 1-2.2, that is, the heat exchanger 1-2.1 is located in the exhaust cavity 1-2.9 of the range hood 1, and Located on the upper part of the centrifugal fan 1-2.2, the oil fume first passes through the centrifugal fan 1-2.2 and then is discharged to the heat exchanger 1-2.1, after passing through the heat exchanger 1-2.1, it is discharged through the air outlet 1-2.5.

[0072] In this embodiment 3, the heat exchanger 1-2.1 is also the evaporator in the air energy water heater. The centrifugal fan 1-2.2 is vertically arranged, and the suction port of the centrifugal fan 1-2.2 faces the left side.

Abstract

The invention provides a range hood with a heat exchange device, which can solve the problem in the prior art that the residual heat of the lampblack is not fully and effectively utilized. The technical solution of the present invention is a range hood with a heat exchange device, including a casing and a fan inside the casing, and an evaporator of an air energy water heater is arranged in the smoking cavity of the casing. In the invention, the evaporator of the air energy water heater is arranged in the range hood, and the evaporator can absorb a large amount of heat energy in the high-temperature oil fume generated during cooking to produce hot water, thereby improving the heat exchange efficiency and energy efficiency ratio.

Description

technical field [0001] The invention belongs to household appliances, in particular to an improved range hood. Background technique [0002] Existing range hoods produce waste heat such as steam and cooking fumes during cooking, which are sucked and exhausted into the atmosphere by the range hood, and the heat energy is not fully and effectively utilized. [0003] There are some deficiencies in the existing air energy heat pump water heaters: 1. Compared with winter, because air energy is used as energy exchange, only a small amount of heat energy in the ambient air is absorbed, and there is not too much air heat energy to be absorbed and utilized. The efficiency is relatively low. 2. The evaporator needs to be equipped with a special fan, relatively speaking, the cost is slightly higher. Contents of the invention [0004] The invention provides a range hood with a heat exchange device, which can solve the problem in the prior art that the residual heat of the lampblack ...
