Based on the consideration, the air-conditioning range hood and the sprayer thereof are designed, so that the cooling efficiency of the condenser can be effectively improved and the cooling noise can be reduced in the process of cooling the condenser by the sprayer.

Referring to fig. 1, an air-conditioning range hood in an embodiment includes a sprayer 10, a condenser 20, and a pump body 30. The liquid substance is sent to the shower 10 through the pump body 30 and is ejected from the shower 10 to the condenser 20.

Specifically, as shown in fig. 1, the liquid supply device is connected to the liquid inlet end 102a of the sprayer 10 through the liquid supply pipeline 40, the pump body 30 is disposed in the liquid supply pipeline 40 and continuously inputs the liquid substance into the sprayer 10, and the liquid substance in the sprayer 10 is output to the nozzle 300 to be sprayed out, so as to cool the condenser 20 with water.

In the present embodiment, the liquid supply device is a condensed water collection tank 50, and the liquid substance is condensed water. Through the arrangement, the recycling of the condensed water is facilitated, and the energy is saved. In other embodiments, the liquid substance may also be tap water or a cooling liquid.

In the present embodiment, the pump body 30 may be a mechanical pump or an electric pump.

Referring to fig. 1 and 2, a sprayer 10 of an air conditioning type range hood in an embodiment includes a housing 100, a partition 200, and a plurality of nozzles 300. Referring to fig. 3, the housing 100 has an inner cavity 101, and the partition 200 is disposed in the housing 100 and divides the inner cavity 101 into an inlet cavity 102 and an outlet cavity 103 disposed adjacent to each other in a transverse direction. Referring to fig. 5, the partition 200 is provided with a notch 210, the liquid inlet chamber 102 is communicated with the liquid outlet chamber 103 through the notch 210, the bottom wall 104 of the liquid outlet chamber is inclined with respect to the horizontal plane with the notch 210 as a vertex, and the plurality of nozzles 300 are arranged on the bottom wall 104 of the liquid outlet chamber at intervals.

The liquid substance in the liquid inlet chamber 102 flows into the liquid outlet chamber 103 through the gap 210 and is ejected from the nozzle 300.

Through the arrangement, the liquid inlet cavity 102 and the liquid outlet cavity 103 are arranged adjacently, so that the flow speed of the liquid substances in the liquid inlet cavity 102 to the liquid outlet cavity 103 is reduced and stable, and the liquid substances in the liquid outlet cavity 103 are prevented from being distributed unevenly due to overhigh flow speed; the diapire 104 that goes out the sap cavity uses breach 210 position to set up for the horizontal plane slope as the summit, effectively avoids liquid material to concentrate on being close to breach 210 position department, does benefit to each nozzle 300's flow evenly distributed, improves and sprays the cooling effect, prevents simultaneously that the nozzle 300 that is close to breach 210 position department from producing the noise of dripping because of ponding is many, the flow is big. It should be noted here that the inlet chamber 102 and the outlet chamber 103 are disposed laterally adjacent to each other, i.e. the inlet chamber 102 and the outlet chamber 103 share the partition plate 200 as a sidewall and are laterally spatially independent from each other. Here, the lateral direction refers to the X direction shown in fig. 2.

In this embodiment, the liquid inlet chamber 102 is laterally located on the left side of the liquid outlet chamber 103, the liquid inlet chamber 102 and the liquid outlet chamber 103 are spatially independent from each other, and the liquid substance in the liquid inlet chamber 102 can flow to the liquid outlet chamber 103, so that the structure is compact. In other embodiments, the inlet chamber 102 may be laterally positioned to the right of the outlet chamber 103.
