Description
Technical Field
[0001] The utility model relates to the technical field of range hoods, in particular to an air-conditioning type range hood. Background Art
[0002] In order to improve the user's cooking experience, people have invented various air-conditioning hoods to provide cold air to the kitchen in summer and warm air in winter. The air-conditioning hood integrates the air-conditioning component with the range hood, and an air-conditioning outlet is opened on the shell of the range hood. The air-conditioning hood can work in multiple different modes. As long as the air-conditioning mode is turned on, the air-conditioning outlet will blow out cold air or hot air, which can be blown directly to the cook or to the kitchen, thereby effectively improving the cook's cooking experience. For the air-conditioning hood working in the cooling mode, in order to improve the energy efficiency of the air conditioner, people have designed a structure in which the condenser is installed in the exhaust channel. The exhaust channel also constitutes a heat dissipation channel, that is, the heat of the condenser is taken away by the oil smoke, and the condenser is dissipated to improve its heat exchange effect. Since the condenser temperature is high, if it is only dissipated by the oil smoke airflow, the heat dissipation effect is not good. For this reason, people have invented a structure that uses air-conditioning condensed water to dissipate heat from the condenser, that is, the air-conditioning condensed water is transported to the surface of the condenser, and the condensed water is used to reduce the surface temperature of the condenser, thereby improving its heat exchange effect.
[0003] For example, the Chinese utility model patent with patent number CN202320196584.9 (publication number CN219550622U) discloses a refrigeration-type range hood, which includes an upper box and a lower cavity. An air conditioner module is provided outside the upper box. The upper box is divided into a smoke exhaust cavity and a heat dissipation cavity. A smoke exhaust fan is installed in the smoke exhaust cavity. The heat dissipation cavity is connected to the smoke exhaust cavity through a heat dissipation outlet. A condenser is installed in the heat dissipation cavity. The condensed water condensed on the evaporator can drip onto or be transported to the condenser. A heat dissipation fan and a water pump are installed below the condenser. The heat dissipation fan and the water pump are coaxially arranged and rotated under the drive of the same motor. The condensed water that has not been consumed by the condenser is pumped back to the condenser through the water pump or discharged to the outside of the upper box. The condensed water that has not been consumed by the condenser in the refrigeration range hood can be pumped back to the condenser through the water pump, and continue to rely on the high temperature of the condenser surface for heat exchange and evaporation consumption, or it can be discharged to the outside of the upper box through the water pump.
[0004] The structure of the condenser also has a great influence on the condensate processing capacity. If the condensate stays on the condenser for too short a time, the condensate processing capacity will be relatively small, and the heat exchange effect of the condensate on the condenser will also be poor. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide an air-conditioning type range hood capable of prolonging the residence time of condensed water on the condenser in view of the current status of the prior art.
[0006] The technical solution adopted by the utility model to solve the above technical problems is: an air-conditioning type range hood, comprising a body and an air-conditioning module arranged on the body, the air-conditioning module comprising a compressor, a condenser and an evaporator, the compressor, the condenser and the evaporator are connected through a refrigerant pipeline, a water delivery pipe for delivering condensed water condensed by the evaporator to the condenser is arranged between the evaporator and the condenser, and the water outlet end of the water delivery pipe is located above the condenser;
[0007] It is characterized in that the condenser comprises a heat exchange plate and a heat exchange tube at least partially passing through the heat exchange plate, and the heat exchange plate is arranged horizontally and located directly below the water outlet end of the water delivery pipe.
[0008] In order to improve the heat exchange effect of the heat exchange plate on the refrigerant in the heat exchange tube, the heat exchange tube extends in a circuitous manner on the heat exchange plate to increase the extension length of the heat exchange tube in the heat exchange plate.
[0009] In order to allow the heat exchange tube to extend in a circuitous manner on the heat exchange plate, a plurality of sockets are provided on the heat exchange plate. The heat exchange tube includes a straight tube and a U-shaped tube. The ends of two adjacent straight tubes are connected by a U-shaped tube. Each of the straight tubes extends vertically and is inserted in a socket. Among the two straight tubes located at the ends of the heat exchange tube, the end of one of the straight tubes serves as an inlet, which is connected to the compressor through a refrigerant pipeline, and the end of the other straight tube serves as an outlet, which is connected to the evaporator through a refrigerant pipeline.
[0010] In order to further extend the extension length of the heat exchange tube in the heat exchange plate, the inlet and the outlet are located on the same side of the heat exchange plate to further improve the heat exchange effect of the heat exchange plate on the heat exchange tube.
[0011] In order to further extend the extension length of the heat exchange tube in the heat exchange plate, the sockets are arranged in sequence at intervals along the length direction of the heat exchange plate, and the sockets arranged in a row constitute a socket group. There are at least two groups of socket groups and they are arranged in sequence at intervals along the width direction of the heat exchange plate. The straight tubes in the sockets of two adjacent groups of sockets located on the same side are connected by a U-shaped tube.
[0012] In order to further extend the extension length of the heat exchange tube in the heat exchange plate, the straight tube with an inlet and the straight tube with an outlet are inserted in two sockets of different socket groups. Along the length direction of the heat exchange plate, the socket with the straight tube with an inlet is the first socket of the corresponding socket group, and the socket with the straight tube with an outlet is the last socket of the corresponding socket group.
[0013] The heat exchange plate can be provided as a plate with a relatively large thickness. To facilitate processing and manufacturing, the heat exchange plate can be provided in multiple numbers at intervals in the upper and lower directions, and the insertion holes on each of the heat exchange plates correspond to each other in the vertical direction.
[0014] In order to ensure the working performance of the air conditioning module, the condenser needs to be cooled. The body is provided with a cooling cavity, and the body is provided with a cooling air inlet and a cooling air outlet connected to the cooling cavity. The cooling air inlet is connected to the outside world. A cooling fan is provided in the cooling cavity, and the air inlet of the cooling fan is connected to the cooling air inlet, and the air outlet of the cooling fan is connected to the cooling air outlet. The cooling fan draws cold air from the outside into the cooling cavity to cool the condenser.
[0015] Preferably, along the direction of the refrigerant flowing from the inlet to the outlet, the flow direction of the airflow is opposite to the flow direction of the refrigerant. In this way, the flow direction of the airflow is opposite to the flow direction of the refrigerant, forming a countercurrent heat exchange, which is similar to the principle of Tian Ji's horse racing and has a good heat dissipation effect on the condenser.
[0016] Preferably, a smoke exhaust cavity is further provided on the machine body, and the heat dissipation air outlet is communicated with the smoke exhaust cavity, so that the airflow blown out from the heat dissipation fan is finally discharged from the smoke exhaust cavity.
[0017] In order to facilitate the condensed water to flow to the condenser, the condenser is located below the evaporator, so that the condensed water flows downward under the action of gravity, and there is no need to set up power components such as water pumps to drive the water flow.
[0018] Compared with the prior art, the advantages of the utility model are as follows: the utility model arranges the heat exchange plate horizontally, so that after the condensed water drops on the heat exchange plate, it will stay on the heat exchange plate for a longer time and spread over a large area, thereby improving the heat dissipation effect on the condenser; compared with the method of arranging the heat exchange plate vertically, after the condensed water drops on the heat exchange plate, it will quickly slide down under the action of gravity, and the contact time with the heat exchange plate is shorter, so the heat dissipation effect on the condenser is also poor.

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0029] like Figures 1 to 9 As shown, the air-conditioned range hood of this preferred embodiment includes a body 1 and an air-conditioning module arranged on the body 1, the air-conditioning module includes a compressor 2, a condenser 3 and an evaporator 4, the compressor 2, the condenser 3 and the evaporator 4 are connected by a refrigerant pipeline, and the working principle of the air-conditioning module is the same as the working principle of the existing air conditioner. Figure 1 The arrow directions at the condenser 3 and the evaporator 4 are the air inlet directions at the condenser 3 and the evaporator 4, respectively.
[0030] The machine body 1 is provided with a heat dissipation chamber 11 and a smoke exhaust chamber 12. The heat dissipation chamber 11 is provided with a heat dissipation fan 5 and a condenser 3. All of the above are prior arts. The arrangement of the compressor 2 and the evaporator 4 may refer to the prior art.
[0031] A water pipe 41 is provided between the evaporator 4 and the condenser 3 for transporting the condensed water condensed by the evaporator 4 to the condenser 3. The water outlet end of the water pipe 41 is located above the condenser 3, and the condenser 3 is located below the evaporator 4. In this way, the condensed water flows downward under the action of gravity, and there is no need to set up a power component such as a water pump to drive the water flow.
[0032] The condenser 3 includes a heat exchange plate 31 and a heat exchange tube 32 partially passing through the heat exchange plate 31. The heat exchange plate 31 is arranged horizontally and is located directly below the water outlet end of the water pipe 41. In this way, after the condensed water drops onto the heat exchange plate 31, it will stay on the heat exchange plate 31 for a long time and have a large spreading area, so as to improve the heat dissipation effect of the condenser 3.
[0033] In order to improve the heat exchange effect of the heat exchange plate 31 on the refrigerant in the heat exchange tube 32, the heat exchange tube 32 extends in a circuitous manner on the heat exchange plate 31. In this embodiment, a plurality of plug holes 311 are provided on the heat exchange plate 31, and the heat exchange tube 32 includes a straight tube 321 and a U-shaped tube 322. The ends of two adjacent straight tubes 321 are connected by the U-shaped tube 322. Each straight tube 321 extends vertically and is inserted in a plug hole 311. The end of one of the straight tubes 321 at the end of the heat exchange tube 32 is used as an inlet 323, and the inlet 323 is connected to the compressor 2 through the refrigerant pipeline. The end of the other straight tube 321 is used as an outlet 324, and the outlet 324 is connected to the evaporator 4 through the refrigerant pipeline. The inlet 323 and the outlet 324 are located on the same side of the heat exchange plate 31, so as to further improve the heat exchange effect of the heat exchange plate 31 on the heat exchange tube 32.
[0034] The plug holes 311 are arranged at intervals in sequence along the length direction of the heat exchange plate 31. The plug holes 311 arranged in a row constitute a plug hole group. There are at least two plug hole groups and they are arranged at intervals in sequence along the width direction of the heat exchange plate 31. The straight tubes 321 in the plug holes 311 on the same side of two adjacent plug hole groups are connected by U-shaped tubes 322. A convex bump 312 is also provided between two adjacent plug hole groups to increase the spacing between the two adjacent plug hole groups 311, increase the extension length of the heat exchange tube 32 in the heat exchange plate 31, that is, extend the flow path of the refrigerant in the heat exchange plate 31, and improve the heat exchange effect of the refrigerant.
[0035] Similarly, the straight tube 321 with the inlet 323 and the straight tube 321 with the outlet 324 are inserted in two sockets 311 of different socket groups. Along the length direction of the heat exchange plate 31, the socket 311 with the straight tube 321 with the inlet 323 is inserted as the first socket 311 of the corresponding socket 311 group, and the socket 311 with the straight tube 321 with the outlet 324 is inserted as the last socket 311 of the corresponding socket 311 group, so as to increase the extension length of the heat exchange tube 32 in the heat exchange plate 31.
[0036] The heat exchange plate 31 can be provided as a thick plate. To facilitate processing and manufacturing, in this embodiment, a plurality of heat exchange plates 31 are provided at intervals up and down, and the insertion holes 311 on each heat exchange plate 31 correspond to each other in the vertical direction.
[0037] The machine body 1 is provided with a heat dissipation air inlet and a heat dissipation air outlet connected to the heat dissipation cavity 11. The heat dissipation air inlet is connected to the outside, and the heat dissipation air outlet is connected to the smoke exhaust cavity 12. A heat dissipation fan 5 is provided in the heat dissipation cavity 11. The air inlet of the heat dissipation fan 5 is connected to the heat dissipation air inlet, and the air outlet of the heat dissipation fan 5 is connected to the heat dissipation air outlet. The heat dissipation fan 5 draws cold air from the outside into the heat dissipation cavity 11 to dissipate heat for the condenser 3. The airflow blown out from the heat dissipation fan 5 is finally discharged from the smoke exhaust cavity 12.
[0038] Along the direction of the refrigerant flowing from the inlet 323 to the outlet 324, the flow direction of the airflow is opposite to the flow direction of the refrigerant. In this way, the flow direction of the airflow is opposite to the flow direction of the refrigerant, forming a countercurrent heat exchange, which is similar to the principle of Tian Ji's horse racing, and has a good heat dissipation effect on the condenser 3. Figure 5 The arrow in the figure indicates the direction of air flow. Figure 5 The direction of the airflow is described as from bottom to top, and the inlet 323 is located above the outlet 324, that is, the flow direction of the refrigerant is from top to bottom.
