Description

Technical Field

[0001] The invention relates to a kitchen air conditioning system. Background Art

[0002] The kitchen is the main place for people to cook, and the quality of the kitchen air environment directly affects the cooking experience. The kitchen is hot in summer and cold in winter, and there is a need for cooling and heating. For this reason, people have invented various kitchen air conditioners to cool the kitchen air in summer and provide warm air to the kitchen in winter to improve cooking comfort.

[0003] The basic form of the existing kitchen air conditioner is not much different from that of ordinary air conditioners. Generally, there are two forms. One is the split type of internal and external units, that is, the external unit is located outdoors and the internal unit is located indoors. The internal and external units each have a motor fan. The connection method of the kitchen air conditioner with split internal and external units needs to be connected through pipes, and holes need to be opened on the wall, which destroys the decoration. An external unit needs to be hung outdoors, which is difficult to install and the structure is not compact enough. The other is the internal and external units are integrated structures. Although the evaporator and condenser of the air conditioner can be installed indoors, a larger area of ​​the wall needs to be destroyed to install the heat exhaust pipe of the condenser, which not only increases the difficulty of installation, but also affects the beauty of the room. In addition, due to the limited space in the kitchen, the volume of the kitchen air conditioner cannot be too large. Therefore, there are major problems in the heat dissipation of the kitchen air conditioner. If the kitchen air conditioner cannot dissipate heat in time during use, the energy efficiency of the air conditioner will be greatly reduced. However, the existing kitchen air conditioner and the range hood work independently of each other, and the two cannot be linked. The heat generated by the kitchen air conditioner cannot be discharged to the outside through the fan of the range hood. Therefore, how to discharge the heat generated by the kitchen air conditioner through the range hood has become a problem that people need to solve urgently.

[0004] Although there are products such as air-conditioning hoods on the market, that is, air-conditioning components are added to the range hood platform, which can realize all the functions of the range hood and the functions of the air conditioner at the same time. However, these air-conditioning hoods often simply merge the functions of the traditional air-conditioning indoor unit and the traditional range hood, and the air-conditioning outdoor unit still needs to be installed separately outdoors. This type of air-conditioning range hood is not integrated enough, and the installation is relatively cumbersome. Moreover, the pipe and line connections between the indoor and outdoor units of the air conditioner will also damage the wall. In addition, during the use of the air-conditioning hood, the evaporator of the air conditioner will produce condensed water, which is currently discharged to the outside through a water pipe. There is no other discharge method, and the condensed water has not been effectively utilized. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a kitchen air conditioning system that can use at least one condenser in the smoke exhaust channel to process air-conditioning condensate and improve the heat exchange efficiency of the condenser in response to the above-mentioned existing technical status.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the kitchen air conditioning system includes an air conditioning component and an oil fume suction component, the air conditioning component includes a compressor, a condenser and an evaporator, the compressor, the condenser and the evaporator are connected by a refrigerant pipeline, the oil fume suction component includes a casing and a smoke exhaust channel arranged in the casing, and is characterized in that: the condenser includes a first condenser and a second condenser connected in series on the refrigerant pipeline in sequence, the first condenser and the second condenser are both arranged in the smoke exhaust channel, an air outlet channel is also provided in the casing, the air outlet of the air outlet channel is fluidly connected to the kitchen room, the evaporator is arranged in the air outlet channel, and a condensate conveying device is also provided in the casing for conveying condensed water generated by the evaporator to the first condenser and / or the second condenser and allowing the condensed water to flow along the surface of the above-mentioned condenser.

[0007] Preferably, the first condenser is connected in series to the refrigerant pipeline between the second condenser and the compressor, and the condensed water generated by the evaporator is transported to the first condenser by the condensed water transport device.

The water distributor is strip-shaped and arranged horizontally along the upper edge of the first condenser. The water distributor has a water inlet and a water outlet. The water inlet is connected to the water outlet of the water pump, and the water outlets are evenly spaced along the length direction of the water distributor.

[0014] In order to make the condensed water flow evenly through each flat tube of the condenser, the water outlet of the water distributor corresponds one by one to the first flat tube of the first condenser.

The water outlet on the side corresponding to the air inlet has the largest diameter, and the water outlet on the side corresponding to the liquid outlet has the smallest diameter. In addition, the diameter of the water outlet gradually decreases from the corresponding side of the air inlet to the corresponding side of the liquid outlet.

[0016] In order to make the water outlet of the water distributor more uniform, there are at least three water inlets and they are evenly spaced along the length direction of the water distributor (34), and the condensed water flowing out of the water pump outlet is evenly distributed to each of the water inlets through a water distribution device.

[0018] In order to collect the condensed water dripping from the second condenser, a water receiving box is provided at the bottom of the second condenser, and the drainage port of the water receiving box is connected to the oil cup through a drainage pipe.

[0019] The smoke exhaust channel and the air outlet channel can be distributed in a variety of ways. Preferably, a fume exhaust fan is installed inside the casing, and the smoke exhaust channel and the air outlet channel are arranged above the range hood and distributed left and right with respect to each other. Along the direction of oil fume flow, the smoke exhaust channel is arranged downstream of the air outlet of the range fume exhaust fan.

[0020] Further preferably, the smoke exhaust channel includes a first smoke exhaust channel and a second smoke exhaust channel, and a duct switching valve is installed at the entrance of the first smoke exhaust channel and the second smoke exhaust channel for switching one of the first smoke exhaust channel and the second smoke exhaust channel to be connected to the air outlet of the range fumes exhaust fan, and the condenser is arranged in the first smoke exhaust channel.

[0037] The present invention is further described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 and Figure 2 As shown, the kitchen air conditioning system of this embodiment includes an air conditioning component and a fume extraction component. The air conditioning component includes a compressor 11, a condenser 12 and an evaporator 13. The compressor 11, the condenser 12 and the evaporator 13 are connected through a refrigerant pipeline 14. A throttling component 15 is installed on the refrigerant pipeline 14 between the condenser 12 and the evaporator 13. A refrigerant flows through the refrigerant pipeline 14. Common refrigerants can be water, ethylene glycol or propylene glycol, etc. The specific working principle of the air conditioning component is the same as that of the existing air conditioner, and will not be described in detail here.

[0039] The oil fume extraction assembly of this embodiment has a housing 20, in which an oil fume extraction fan 21 is arranged. The oil fume extraction fan 21 is installed at the lower part of the housing 20. The upper part of the housing 20 is provided with a mutually isolated smoke exhaust passage 22 and an air outlet passage 23. Along the oil fume flow direction, the smoke exhaust passage 22 is arranged downstream of the air outlet of the oil fume extraction fan 21. Figure 1 The direction indicated by the middle arrow A is right, and the air outlet channel 23 is located on the right side of the smoke exhaust channel 22. In this embodiment, the compressor 11 is integrated on the housing 20, and the compressor 11 is on the right side of the range fumes fan 21 and is located below the air outlet channel 23.

[0040] The smoke exhaust channel 22 of this embodiment includes a first smoke exhaust channel 221 and a second smoke exhaust channel 222. An air channel switching valve 4 is installed at the entrance of the first smoke exhaust channel 221 and the second smoke exhaust channel 222 to switch one of the first smoke exhaust channel 221 and the second smoke exhaust channel 222 to be connected to the air outlet of the oil fume exhaust fan 21. A condenser 12 and an electrostatic purification device 5 are installed in the first smoke exhaust channel 221, and the electrostatic purification device 5 is arranged upstream of the condenser 12 along the oil fume flow direction, so as to prevent the oil fume from contaminating the condenser 12.

[0041] The first smoke exhaust channel 221 of this embodiment has a first smoke exhaust port 223, and the second smoke exhaust channel 222 has a second smoke exhaust port 224. The first smoke exhaust port 223 and the second smoke exhaust port 224 are independent of each other. The first smoke exhaust port 223 and the second smoke exhaust port 224 are connected to the same smoke exhaust pipe 6.

[0042] The housing 20 is provided with an air inlet (not shown in the figure) and an air outlet 24 of the air outlet passage 23. The air inlet can be connected to the kitchen room or to the outside. The air outlet 24 can be arranged on the front of the housing 20 or on the top of the housing 20. When the air outlet is arranged on the front of the housing 20, the air conditioning air is blown directly from the air outlet to the kitchen room. When the air outlet is arranged on the top of the housing 20, the air outlet is connected to the kitchen room through an air duct (not shown in the figure).

[0043] The evaporator 13 and the air outlet fan 25 are installed in the air outlet passage 23. The air outlet fan 25 blows air toward the air outlet 24 to blow the refrigerated air into the kitchen from the air outlet 24.

[0044] like Figure 2 and Figure 3 As shown, the condenser 12 of this embodiment includes a first condenser 121 and a second condenser 122, and the first condenser 121 is connected in series to the refrigerant pipeline 14 between the second condenser 122 and the compressor 11, that is, the refrigerant discharged from the compressor 11 first enters the first condenser 121, and then enters the second condenser 122. In this embodiment, the first condenser 121 and the second condenser 122 are both inclined relative to the vertical plane, and the first condenser 121 is located above the second condenser 122, the vertical projection of the first condenser 121 all falls into the second condenser 122, and the first condenser 121 is located downstream of the second condenser 122 along the flow direction of the oil smoke.

[0045] The first condenser 121 of this embodiment includes a first liquid collecting pipe 1211 and a first flat tube 1212 connected between the first liquid collecting pipes. Figure 5 As shown, the first flat tube 1212 is arranged vertically. The second condenser 122 includes a second liquid collecting pipe 1221 and a second flat tube 1222 connected between the second liquid collecting pipes. Figure 8 As shown, the second flat tubes 1222 are arranged horizontally.

[0046] When the system is working, the evaporator 13 will produce condensed water. In this embodiment, the condensed water is transported to the surface of the first condenser 121 through the condensed water transport device 3, and the condensed water can flow along the surface of the first condenser 121, that is, flow downward along the first flat tube 1212.

[0047] like Figures 4 to 7 As shown, the condensate conveying device 3 of this embodiment includes a water receiving pan 31, a water tank 32, a water pump 33 and a water distributor 34, wherein the water receiving pan 31 is arranged in the air outlet channel 23 and below the evaporator 13, and the condensate received by the water receiving pan 31 flows into the water tank 32 through the water guide pipe 35, and the condensate flowing into the water tank 32 is transported to the inside of the water distributor 34 through the water pump 33. The water distributor 34 is arranged above the first condenser 121, and the water distributor 34 is strip-shaped and arranged horizontally on the upper edge of the first condenser 121. The water distributor 34 has a water inlet 341 and a water outlet 342, and the water inlet 341 is connected to the water outlet of the water pump 33, and the water outlet 342 is evenly spaced along the length direction of the water distributor 34, so that the condensate flowing out of the water distributor 34 can flow evenly downward along the upper surface of the first condenser 121.

[0048] The water distributor 34 of this embodiment has a plurality of water outlets 342 which are evenly spaced along the length direction of the water distributor 34. Specifically, the number of water outlets 342 is equal to the number of flat tubes 123, and the water outlets 342 correspond to the flat tubes 123 one by one. In this embodiment, the caliber of each water outlet 342 is equal, that is, the water output of each water outlet 342 is the same, so that the amount of water flowing through each flat tube 123 is equal, and the flat tubes 123 are evenly cooled.

[0049] like Figure 5 As shown, an air inlet 1213 is provided at one end of the first collecting pipe 1211 located at the bottom, and a liquid outlet 1214 is provided at the other end of the first collecting pipe 1211. Considering that the refrigerant temperature on the air inlet side is higher and the refrigerant temperature on the liquid outlet side is lower, in order to make the water output of each water outlet 342 of the water distributor 34 compatible with the refrigerant temperature flowing through the condenser, the water outlet 342 can be set as follows: the water outlet 342 on the side corresponding to the air inlet 1213 has the largest diameter, and the water outlet 342 on the side corresponding to the liquid outlet 1214 has the smallest diameter, and the diameter of the water outlet 342 gradually decreases from the corresponding side of the air inlet 1213 to the corresponding side of the liquid outlet 1214.

[0050] In addition, a return water box 36 is provided at the bottom of the condenser 12, and the water in the return water box 36 can flow back to the water tank 32 through the return water pipe 37. In this way, the condensed water that is not evaporated by the first condenser 121 can flow into the return water box 36 and then flow back to the water tank 32, realizing the recycling of the condensed water.

[0051] like Fig. 9 As shown, the water distributor 34 has four water inlets 341 and is evenly spaced along the length direction of the water distributor 34. The condensed water flowing out of the outlet of the water pump 33 is evenly distributed to each water inlet 341 through the water distribution device 38, so that the condensed water can flow through the surface of the first condenser 121 more evenly, thereby improving the evaporation efficiency of the condensed water and the heat exchange efficiency of the first condenser 121.

[0052] like Fig.10 As shown, a water receiving box 6 is provided at the bottom of the second condenser 122, and a drain port of the water receiving box 6 is connected to an oil cup 8 through a drain pipe 7. When the system is working, condensed water dripping from the second condenser 122 can eventually flow into the oil cup 8.

[0053] The kitchen air conditioning system works in cooling mode, and its working principle is as follows:

[0054] When the range hood and the air conditioner are both turned on, the oil smoke is discharged through the first smoke exhaust channel 221, and the oil smoke airflow passing over the surface of the condenser 12 can cool down and dissipate the heat of the first condenser 121, thereby reducing the temperature of the refrigerant flowing through the first condenser 121, thereby improving the heat exchange effect of the first condenser 121, and the condensed water of the evaporator 13 is transported to the first condenser 121 by the condensed water conveying device 3 and flows downward along the upper surface of the first condenser 121. On the one hand, the first condenser 121 is further cooled, so that the temperature of the refrigerant flowing into the second condenser 122 is also reduced, thereby further improving the overall heat exchange effect of the condenser, thereby improving the energy efficiency of the air conditioner and realizing the effective use of the condensed water. On the other hand, the condensed water can be heated by the first condenser 121 and evaporated and then discharged from the first smoke exhaust channel 221. Even if the condensed water is not evaporated by the first condenser 121 and drips onto the second condenser 122, it will be evaporated by the second condenser 122 and the heat exchange effect of the second condenser 122 will be improved. At the same time, cold air is sent into the kitchen room from the air outlet 24 of the air outlet channel 23.

[0055] In addition, the oil fume extraction component of the present invention is not limited to the structure of installing the oil fume extraction fan inside the casing. The oil fume extraction component can also adopt a non-powered structure, that is, the oil fume extraction component only retains the smoke collecting shell, and the oil fume extraction fan is placed outside the casing. For example, the oil fume extraction fan can be installed on the top of the public flue of the building.

[0056] The "fluid connection" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part respectively), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
