Description

Technical Field

[0001] The utility model relates to a range hood, in particular to a condensed water circulation system of a refrigeration-type range hood. Background Art

[0002] Various refrigeration-type range hoods are currently available. These add an air conditioning component to the range hood platform, achieving both the functions of a range hood and an air conditioner. When operating in cooling mode, the condenser needs to dissipate heat. Currently, this condenser is typically placed within the fume duct and cooled using a fume extraction fan. Alternatively, condensed water from the air conditioner can be used to dissipate heat. For example, in the Chinese utility model patent application number 202220040537.0 (authorized by the public number CN 217685714U), "A Water Pump Flow Control System and Air-Conditioning Range Hood," when operating in air-conditioning mode (cooling mode), condensed water on the evaporator flows into the water collection tray. The condensed water in the water collection tray flows into the water box through the water inlet pipe. Under the action of the water pump, the condensed water in the water box is transported to the liquid distributor through the outlet pipe, and then flows from the liquid distributor to the surface of the condenser. This, on the one hand, cools the condenser, further improving its heat exchange efficiency and achieving effective utilization of the condensed water. On the other hand, the condensed water is heated and evaporated by the condenser and discharged through the first exhaust channel. The unevaporated condensed water flows into the water collection tray and then returns to the water box through the return pipe for reuse. During use, this refrigerated range hood will accumulate condensed water near the water box inlet in the water circulation system. This condensed water can drip onto the chassis, easily causing rust. In summary, there is a need to further improve the condensed water circulation system of the existing refrigeration-type range hood. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a condensation water circulation system for a refrigeration type range hood in response to the above-mentioned existing technical status, which avoids the generation of condensation water at the water inlet and the back of the water box.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a condensed water circulation system of a refrigeration range hood, comprising a heat dissipation module, an internal machine module and a water storage box, the water outlet of the internal machine module is connected to the water storage box through a water inlet pipe, the condensed water in the water storage box can be transported to the heat dissipation module through the water outlet pipe, and the unconsumed condensed water of the heat dissipation module flows back to the water storage box through the return pipe, and is characterized in that: an inlet pipe column and a return water pipe column are provided in the water storage box, the inlet pipe is connected to the inlet pipe column, the return pipe is connected to the return water pipe column, and the bottom of the inlet pipe column is connected to the bottom of the return water pipe column.

[0005] In order to fully mix the cold water flowing into the water inlet pipe and the hot water flowing into the water return pipe, the water inlet pipe column and the water return pipe column are both provided with grooves and are arranged opposite to each other.

[0006] In order to make the cold water and hot water mix more fully, the bottom of the water inlet pipe column and the bottom of the return water pipe column are connected through a blocking dam.

[0007] The water inlet pipe column and the water return pipe column can have various structures. Preferably, the diameters of the water inlet pipe column and the water return pipe column gradually decrease from the bottom to the head.

[0008] Further preferably, the water inlet pipe column and the water return pipe column are both extended upward from the inner bottom of the water storage box.

[0009] In order to smoothly transport the condensed water in the water storage box to the heat dissipation module, the condensed water circulation system also includes a water pump. Under the action of the water pump, the condensed water in the water storage box can be transported to the heat dissipation module through the water outlet pipe.

[0010] In order to prevent the condensed water dripping into the water storage box from flowing out from the overflow port, the water storage box has an overflow port, and the inner bottom of the water storage box is provided with a water retaining bar that can prevent the condensed water dripping into the water storage box from flowing out from the overflow port.

[0011] More preferably, the water retaining bar is provided between the condensed water dripping area and the overflow outlet, so as to ensure that the water retaining bar can retain the condensed water.

[0012] As a preferred embodiment of any of the above solutions, the heat dissipation module includes a condenser and a heat dissipation fan, and the condensed water in the water storage box is transported to the surface of the condenser through a water outlet pipe.

[0013] As a preferred embodiment of any of the above solutions, the indoor unit module includes an evaporator and an indoor unit fan, and the condensed water condensed on the evaporator flows into the water storage box through a water inlet pipe.

[0014] Compared with the prior art, the advantages of the present invention are that a water inlet pipe column and a return pipe column are provided in the water storage box of the condensation water circulation system of the refrigeration type range hood. The condensed water (cold water) flowing out of the water inlet pipe goes to the water inlet pipe column, and the water (hot water) that has not been completely evaporated and processed flows out of the return pipe goes to the return pipe column. Since the bottom of the water inlet pipe column is connected with the bottom of the return pipe column, the cold water and the hot water are mixed to become warm water. In this way, no condensed water will be generated near the water inlet, especially on the back of the water storage box, and will not drip onto the bottom plate to cause it to rust. In addition, the thermal insulation cotton at the bottom of the water storage box is eliminated, saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0019] Such as 1 and Figure 2 As shown, the condensed water circulation system of the refrigeration-type range hood of this embodiment includes a heat dissipation module 1, an internal unit module 2 and a water storage box 3, wherein the heat dissipation module 1 includes a condenser 11 and a heat dissipation fan 12, and the internal unit module 2 includes an evaporator 21 and an internal unit fan 22. The heat dissipation module 1 and the internal unit module 2 need to be used in conjunction with a compressor (not shown in the figure). The compressor, the heat dissipation module 1 and the internal unit module 2 constitute an air-conditioning component, and its working principle is the same as that of the existing air-conditioning, which will not be described in detail here. When the range hood is working in the cooling mode, condensed water will condense on the surface of the evaporator 21, and the condenser 11 will generate heat, which needs to be dissipated. In this embodiment, the internal unit module 2 has a water outlet, which is connected to the water storage box 3 through the water inlet pipe 4. The condensed water on the surface of the evaporator 21 flows into the water storage box 3 through the water inlet pipe 4. The condensed water in the water storage box 3 can be transported to the condenser 11 of the heat dissipation module 1 via the outlet pipe 5 and a water pump (not shown). The condensed water is used to cool and dissipate heat from the condenser 11. To ensure uniform heat dissipation of the condenser 11, a liquid distributor can be installed on the top of the condenser, through which the condensed water flows and distributes it evenly. The heat dissipation module 1 has a return port, which is connected to the water storage box 3 via a return pipe. Condensed water not consumed by the condenser flows back into the water storage box 3 via the return pipe 6 for recycling.

[0020] Combine Figure 3 As shown, the water storage box 3 is equipped with an inlet pipe 31 and a return pipe 32. Each of these pipes is provided with a slot 33 and is positioned opposite each other. The bottom of the inlet pipe 31 and the bottom of the return pipe 32 are connected by a barrier 34. Both the inlet pipe 31 and the return pipe 32 extend upward from the inner bottom of the water storage box 3, and their diameters gradually decrease from the bottom to the top. The upper end of the inlet pipe 4 is connected to the water outlet of the internal unit module 2, and the lower end is connected to the inlet pipe 31. The upper end of the return pipe 6 is connected to the return outlet of the heat dissipation module 1, and the lower end is connected to the return pipe 32.

[0021] In addition, an overflow port 35 is provided on the side wall of the water storage box 3, and a water retaining bar 36 is provided on the inner bottom of the water storage box 3. The water retaining bar 36 is provided between the condensed water dripping area 37 and the overflow port 35, thereby preventing the condensed water dripping into the water storage box 3 from flowing out of the overflow port. In the refrigeration-type range hood of this embodiment, the condensed water on the capillary tube will drip onto the condensed water dripping area 37.

[0022] During operation, the condensed water (cold water) flowing out of the water inlet pipe 4 enters the water inlet pipe column 31 and then flows from the groove 33 of the water inlet pipe column to the bottom to the blocking bar 34; the water that cannot be completely evaporated and flows out of the return pipe 6 (hot water, heated by the condenser) enters the return pipe column 32 and then flows from the groove 33 of the return pipe column 32 to the bottom to the blocking bar 34; at this time, the cold water and the hot water are mixed to become warm water, so that no condensed water will be generated near the water inlet of the water storage box 3, especially the back of the water storage box 3, and will not drip onto the bottom plate to cause it to rust, and the insulation cotton at the bottom of the water storage box is eliminated, saving costs.
