[0002] The air conditioning hood can generate cold air while extracting oil smoke, thus optimizing the cooking environment. At present, the air conditioning hood can use a common flue for heat dissipation, that is, the refrigeration system and the hood share the same flue for heat dissipation.

[0003] The condenser of the refrigeration system is set in the flue, and the heat dissipated by the condenser is discharged into the public flue together with the oil smoke. When a larger cooling capacity is required, the heat dissipation of the condenser needs to be increased, that is, the heat dissipation surface of the condenser needs to be increased, which will cause excessive wind resistance in the flue and affect the efficiency of smoke extraction; and in order to reduce wind resistance, the heat dissipation of the condenser cannot be guaranteed, which leads to poor cooling effect of the refrigeration system. Therefore, it is difficult for the refrigeration system and the range hood to share the same channel to dissipate heat to the public flue to meet both the cooling capacity and the air volume of the range hood.

[0008] The electric refrigeration module is connected to the partition wall, and the heat absorption part of the electric refrigeration module is located in the heat exchange cavity, and the heat dissipation part of the electric refrigeration module is located in the heat dissipation cavity; along the air flow direction of the heat exchange cavity, the heat absorption part is located in front of the condenser, so that the flue gas passes through the heat absorption part first and then passes through the condenser.

[0009] Furthermore, an auxiliary fan is provided in the heat dissipation cavity to generate an airflow from the air inlet to the air outlet.

[0010] Furthermore, the auxiliary fan is arranged at the air inlet; or, along the air flow direction of the heat dissipation cavity, the auxiliary fan is arranged between the air outlet and the electric refrigeration module.

[0013] The heat dissipation portion includes heat dissipation fins.

[0014] Furthermore, the air conditioning refrigeration mechanism includes a shell, the shell is provided with an air inlet, and the air inlet is provided with an oil fume filter and / or an air inlet grille.

[0015] Furthermore, along the airflow direction of the heat dissipation cavity, the number of the electric refrigeration modules is at least two.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1 and Figure 2 As shown, the refrigeration system provided by the utility model includes: a heat exchange chamber 20, an air conditioning refrigeration mechanism 34 and an electric refrigeration module. The lower end of the heat exchange chamber 20 is connected to the smoke hood 10, and the upper end is connected to the fan assembly.

[0043] The heat exchange chamber 20 is provided with a heat exchange chamber 21 and a heat dissipation chamber 22 separated by a partition wall 26. The heat exchange chamber 21 is provided with a smoke inlet and a smoke outlet communicating with the inside and outside thereof. The heat exchange chamber 21 is connected between the smoke hood 10 and the fan assembly, and the three are arranged in sequence along the vertical direction. The oil smoke sucked in by the smoke hood 10 passes through the heat exchange chamber 21 and enters the fan assembly, and then is discharged into the public flue.

[0044] like Figure 3 As shown, the heat dissipation chamber 22 is provided with an air inlet and an air outlet communicating with the inside and the outside thereof, and the smoke outlet and the air outlet are both connected to the fan assembly. The number of heat dissipation chambers 22 can be one or two. In this embodiment, the two heat dissipation chambers 22 are respectively arranged on the left and right sides of the heat exchange chamber 21.

[0045] like Figure 4As shown, the air conditioning refrigeration mechanism 34 may include a shell, a cross-flow fan 341 , an air inlet grille 342 , an oil filter 343 , a compressor 35 , an expansion valve 351 , a condenser 211 and an evaporator 344 , and the condenser 211 is located in the heat exchange chamber 21 .

[0046] Among them, Figure 5 As shown, the compressor 35, the evaporator 344, the expansion valve 351 and the condenser 211 are connected end to end, and the working medium circulates therein. The working medium circulates and refrigerates through the refrigeration medium working pipeline 352, the compressor 35 compresses the refrigerant into high-pressure and high-temperature gas, the fan assembly takes away the high temperature in the condenser 211 and discharges it to the public flue by forced convection, and the condenser 211 is converted into low-temperature and high-pressure liquid, the expansion valve 351 expands the high-pressure liquid and reduces its pressure to convert the refrigerant into low-temperature and low-pressure liquid, the cross-flow fan 341 is used to inhale indoor air for forced convection, take away the cold in the evaporator 344, and input the low-temperature airflow into the cooking environment, thereby providing low-temperature air to the user, and realizing the temperature adjustment of the cooking environment.

[0047] like Figure 4 As shown, the air inlet grille 342 and the oil filter 343 are arranged on the bottom surface of the shell, and the indoor air passes through the air inlet grille 342 and the oil filter 343 in sequence and enters the shell. The air inlet grille 342 is used to rectify the airflow, adjust the airflow angle entering the crossflow fan 341, and optimize the inlet airflow organization; the oil filter 343 is used to purify the oil in the air and prevent the oil from entering the air conditioning refrigeration mechanism 34 to affect the refrigeration efficiency. The crossflow fan 341 is arranged inside the shell, and the front of the shell is provided with an outlet 345. The evaporator 344 is arranged between the crossflow fan 341 and the outlet 345. The crossflow fan 341 blows the airflow out from the outlet 345. The airflow absorbs the airflow temperature through the evaporator 344, and the airflow is changed into a low-temperature cold airflow. The outlet angle is adjusted through the outlet 345 to blow into the room, and the cooking environment is cooled to complete the air conditioning of the kitchen environment.

[0048] The electric refrigeration module is connected to the partition wall 26, and the heat absorption part of the electric refrigeration module is located in the heat exchange cavity 21, and the heat dissipation part of the electric refrigeration module is located in the heat dissipation cavity 22; along the airflow direction of the heat exchange cavity 21, the heat absorption part is located in front of the condenser 211, so that the flue gas passes through the heat absorption part first and then passes through the condenser 211.

[0049] like Figure 1As shown, the heat absorption part in the electric refrigeration module may include a semiconductor refrigeration surface 223, and the heat dissipation part may include a semiconductor heat dissipation fin 224. The semiconductor refrigeration surface 223 is attached to the surface of the heat exchange cavity 21, and the semiconductor heat dissipation fin 224 is parallel to the extension direction of the heat dissipation cavity 22, that is, it is arranged in parallel with the vertical direction according to the direction of the airflow, which minimizes the obstruction to the airflow flowing from bottom to top and facilitates the airflow to pass through the fin. The number of electric refrigeration modules in each heat dissipation cavity 22 is at least one, and two are arranged in this embodiment to further reduce the flue gas temperature.

[0050] like Figure 6 As shown, when the air-conditioning hood is working, under the action of the fan assembly, the oil smoke will pass through the heat exchange chamber 21. At the same time, after the electric refrigeration module is working, the heat absorption part of the electric refrigeration module will reduce the temperature around it. After the smoke passes through the heat absorption part, the temperature drops, and the heat exchange efficiency with the condenser 211 is improved, so the burden of the condenser 211 is reduced. Based on the principle of energy conservation, the smoke temperature is initially cooled by using the electric refrigeration module. After the smoke temperature is reduced, the heat dissipation borne by the condenser 211 is reduced. In this way, during production and preparation, the heat dissipation area of ​​the condenser set in the heat exchange chamber 21 can be set smaller, thereby reducing the influence of the condenser 211 on the air duct resistance; at the same time, through the chamber design, the heat generated by the electric refrigeration is directly transferred to the fan assembly, which not only ensures the smoke-inhaling effect of the hood but also improves the cooling effect of the air-conditioning hood. By coordinating the smoke-inhaling amount and the cooling amount, it can not only meet the user's demand for cooling amount, but also ensure the air volume of the hood, and adjust the smoke-inhaling effect and cooling efficiency to a better state, bringing users a better cooking environment.

[0051] Furthermore, an auxiliary fan 222 is provided in the heat dissipation cavity 22 for generating an air flow from the air inlet to the air outlet.

[0052] Specifically, the auxiliary fan 222 can be arranged at the air inlet of the heat dissipation chamber 22, that is, below the electric refrigeration module. The use of the auxiliary fan 222 can reduce the partial pressure of the fan assembly on the heat dissipation chamber 22, so that the negative pressure is concentrated in the heat exchange chamber 21, which is more conducive to improving the smoking efficiency.

[0053] like Figure 7 As shown, in another possible solution, along the airflow direction of the heat dissipation cavity 22, the auxiliary fan 222 is arranged between the air outlet and the electric cooling module. The auxiliary fan 222 is placed inside the heat dissipation cavity 22, and the auxiliary fan 222 is hidden, which is convenient for the installation and use of the equipment and improves the appearance. At the same time, the auxiliary fan 222 is away from the user to reduce noise. At the same time, a rectifier net 225 can be arranged under the auxiliary fan 222 to optimize the airflow and reduce the flow resistance in the heat dissipation cavity 22.

[0054] The filter 221 is arranged at the air inlet to reduce the oil pollution of the electric refrigeration module. The filter 221 is detachable for replacement or cleaning.

[0055] The air-conditioning hood provided by the utility model includes the above-mentioned refrigeration system. Since the air-conditioning hood provided by the utility model adopts the above-mentioned refrigeration system, the air-conditioning hood provided by the utility model also has the advantages of the refrigeration system.

[0056] The fan assembly may include: a chassis cavity 31, a smoke fan 32, and a smoke fan outlet 345 connector. The upper ports of the heat exchange cavity 21 and the heat dissipation cavity 22 are both connected to the chassis cavity 31, the smoke fan 32 is arranged inside the chassis cavity 31, and the smoke fan outlet 345 connector connects the smoke fan 32 and the common flue.

[0057] The air conditioning refrigeration mechanism 34 is connected to the bottom of the chassis cavity 31 ; the air conditioning refrigeration mechanism 34 includes a compressor 35 , a water system and other refrigeration components, and the compressor 35 , the water system and other refrigeration components are located inside the chassis cavity 31 .

[0058] A cover is provided in the chassis cavity 31, and the cover and the chassis cavity 31 enclose a containing space. The outer wall of the cover is a curved surface, and the cross section includes a guide contour line 36, which is used to reduce the eddy current in the air-conditioning range hood chassis cavity 31, optimize the airflow structure in the cavity, and reduce flow losses.

[0059] A flap mechanism 13 can be rotatably connected to the smoke hood 10, and the flap mechanism 13 can open and close the inlet of the smoke hood 10. When the range hood starts, the flip mechanism operates, flips the smoke chamber panel to a predetermined angle to inhale the smoke generated by the smoke source, and transports the smoke to the heat exchange chamber 21 of the air-conditioning range hood. The function is mainly to inhale the smoke from the smoke source and control or adjust the air intake of the air-conditioning range hood.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
