Description

Technical Field

[0001] The utility model relates to a range hood, in particular to a drainage structure of an air-conditioning type range hood. Background Art

[0002] In order to provide cold air to the kitchen in summer and warm air to the kitchen in winter, people invented the air-conditioning range hood, that is, an air-conditioning component is added to the range hood platform, which can realize all the functions of the range hood and the function of the air conditioner at the same time. Among them, the air-conditioning component includes a compressor, a condenser and an evaporator. When working in the air-conditioning mode, the condensed water generated by the evaporator is generally collected through a water box, and then the condensed water is sprayed to the condenser by a water pump for heat dissipation and evaporation. The excess water in the condenser is returned to the water box through the return pipe for repeated evaporation, that is, a technical solution without an external machine and condensed water discharge is realized. However, in the rainy season, due to low temperature and high humidity, there may be a situation where water cannot be treated completely. Therefore, an overflow hole structure is required on the water storage box. When the water in the water storage box is full, it can be discharged from the overflow hole to prevent water from flowing everywhere. The overflow hole generally guides water into the air inlet channel and flows into the oil cup along the oil path, but the viscosity of water is low. When the water flow is too large, splashing will occur, which seriously affects the user experience. For example, the Chinese utility model patent with patent number 202121879024.0 (authorization announcement number CN 216307898U) discloses "A water storage box structure for air-conditioned range hoods". The water storage box structure can be used to collect condensed water in the air conditioner and in the range hood casing through the first condensed water inlet and the second condensed water inlet provided on the box body. In addition, the condensed water in the water storage box can be discharged out of the box body through a water pump, but the problem of water splashing out of the water box cannot be solved. The current common solution is to add a water retaining cover to the water box, and to design a water retaining cover for the range where the return pipe may splash out. Although it can achieve a certain splash-proof effect, the water retaining cover must ensure that the water flow in the return pipe has a certain channel to flow into the water pump suction port, but the channel is easily splashed under the drive of high-speed airflow. In addition, the problem can be solved by increasing the height of the return pipe. However, increasing the height of the return pipe will reduce the pressure of the airflow on the water storage in the water box, increasing the risk of excess water in the condenser falling into the water box through the return pipe due to wind pressure and causing splashing. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a drainage structure of an air-conditioning type range hood capable of diverting condensed water overflowing from a drainage component to prevent splashing in response to the above-mentioned existing technical status.

[0004] The technical solution adopted by the utility model to solve the above technical problems is: a drainage structure of an air-conditioning type range hood, comprising a fan frame, the fan frame having a fan frame side plate and a fan frame back plate, characterized in that: a drainage component is installed on the outside of the fan frame, the drainage component has an overflow hole, the fan frame side plate is provided with a water inlet hole corresponding to the overflow hole, a bracket is installed on the inner side of the fan frame back plate, a drainage diversion channel is formed at the bottom of the bracket, the drainage diversion channel has a water through hole and at least two equal flow outlets, and the water through hole is fluidically connected with the overflow hole.

[0005] In order to enable the water flowing out of the drainage diversion channel to flow down along the fan frame back plate, the fan frame back plate has an inwardly bent water retaining boss, and the vertical projection of the uniform flow outlet falls on the water retaining boss.

[0006] In order to make the water flowing out of the drainage diversion channel finally flow into the oil cup, the air-conditioning type range hood includes an oil cup, and the water flowing out of the uniform flow outlet can flow into the oil cup along the back plate of the fan frame.

[0007] The drainage assembly can be installed at multiple different positions of the wind rack. Preferably, the wind rack has a wind rack bottom plate, which extends outward to the outside of the wind rack side plate, and the drainage assembly is installed on the wind rack bottom plate outside the wind rack side plate.

[0008] In order to allow the water flowing out of the overflow hole to flow smoothly into the drainage diversion channel, a water flow channel is formed between the water hole of the drainage diversion channel and the overflow hole of the drainage component.

[0009] Further preferably, the space enclosed by the side panels of the fan rack and the side portions of the bracket forms the water flow channel.

[0010] In order to obtain a better flow balancing effect, the flow balancing outlets are arranged at the bottom of the drainage diversion channel and are evenly distributed at intervals.

[0011] Further preferably, the uniform flow outlets are slot holes with the same hole diameter.

[0012] As a preferred embodiment of any of the above schemes, the bracket is a sound-absorbing cotton bracket for installing sound-absorbing cotton.

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 6 As shown, the drainage structure of the air-conditioning range hood of this embodiment includes a fan frame 1, and the fan frame 1 has a fan frame side plate 11, a fan frame back plate 12 and a fan frame bottom plate 13. The fan frame bottom plate 13 extends outward to the outside of the fan frame side plate 11, and a drainage component 2 is installed on the fan frame bottom plate 13 outside the fan frame side plate 11. When the air-conditioning range hood is working, the air-conditioning condensed water generated is stored in the water box of the drainage component 2.

[0022] The drainage assembly 2 has an overflow hole 21, and the fan frame side plate 11 is provided with a water inlet hole 111 corresponding to the overflow hole 21. A bracket 3 is installed on the inner side of the fan frame back plate 12. The bracket 3 of this embodiment is a sound-absorbing cotton bracket 3 for installing sound-absorbing cotton. After the sound-absorbing cotton is installed on the sound-absorbing cotton bracket 3, the fan noise can be reduced and the user experience can be improved.

[0023] A drainage diversion channel 31 is formed at the bottom of the bracket 3. The drainage diversion channel 31 has a water hole 32 and at least two equal flow outlets 33, wherein the water hole 32 is fluidly connected with the overflow hole 21, and the equal flow outlets 33 are arranged at the bottom of the drainage diversion channel 21 and are evenly spaced. In this embodiment, the equal flow outlets 33 are slots, and there are three slots with the same aperture size. The wind frame back plate 12 has an inwardly bent water retaining boss 121, and the vertical projection of the equal flow outlet 33 falls on the water retaining boss 121. The water retaining boss 121 plays the role of water retaining and diverting. The water flowing down from the equal flow outlet 33 first drips behind the water retaining boss 121, and then flows downward along the wind frame back plate 12, and finally flows into the oil cup (not shown in the drawing).

[0024] In this embodiment, the space enclosed by the side panels 11 of the fan frame and the side portions of the bracket 3 forms a water flow channel 4, and the overflow hole 21 of the drainage component 2 is arranged above the water hole 32. When the range hood is working, the condensed water of the air conditioner overflows from the overflow hole 21 of the drainage component 2, hits the side wall of the bracket 3, and then flows downward along the water flow channel 4. The cross-sectional area of ​​the water flow channel 4 is more than twice the cross-sectional area of ​​the overflow hole 21, which facilitates the smooth drainage of the condensed water. After the water flows to the bottom of the bracket 3, it flows downward along the back panel 12 of the fan frame into the oil cup. When the water flow is too large, the condensed water that cannot be drained away in time enters the drainage diversion channel 31 through the water hole 32, and then flows out through the equal flow outlet 33 for diversion, and finally flows into the oil cup to prevent splashing due to excessive water flow.
