[0031] For example,Figures 1 to 4 The utility model provides a kind of integrated range hood system, comprising: shell 1, with mutually isolated first cavity 11 and second cavity 12, shell 1 is equipped with oil fume inlet, oil fume outlet, fresh air inlet 13 for being communicated with outdoor and air supply outlet for being communicated with indoor, fresh air inlet 13 and air supply outlet are all communicated with second cavity 12 and form fresh air flow channel;Phase change evaporator 2 is arranged in first cavity 11;Phase change condenser 3 is arranged in second cavity 12, and phase change condenser 3 is higher than phase change evaporator 2 in the height direction of shell 1;Oil fume duct 4 is located in first cavity 11, and it is not communicated with first cavity 11, and oil fume inlet and oil fume outlet are all communicated with oil fume duct 4;Air supply fan 5 is arranged in second cavity 12 and the air outlet end of air supply fan 5 is communicated with air supply outlet;Circulation pipeline group is arranged between phase change evaporator 2 and phase change condenser 3 in shell 1, and circulation pipeline group has first flow channel and second flow channel with opposite flow directions, wherein, first flow channel is used for one-way conduction from phase change evaporator 2 to phase change condenser 3, and second flow channel is used for one-way conduction from phase change condenser 3 to phase change evaporator 2.

[0033] The oil fume duct 4 is arranged in the first cavity 11, and the oil fume in the kitchen can enter the oil fume passage through the oil fume inlet and finally be discharged into the kitchen public flue (an external discharge pipeline can be arranged outside the shell 1 and communicated with the oil fume outlet, and the external discharge pipeline is communicated with the kitchen public flue).The temperature of the oil fume is relatively high, and the heat can be transferred to the air in the first cavity 11 to increase the temperature of the air, and the temperature difference between the heated air and the refrigerant in the phase change evaporator 2 is larger, so that the phase change of the refrigerant in the phase change evaporator 2 is faster, the heat exchange efficiency of the phase change evaporator 2 is improved, the circulation of the refrigerant is accelerated, the heat exchange efficiency of the phase change condenser 3 is improved, and the heat exchange efficiency of the fresh air is improved, so that the heating effect of the fresh air is better.The integrated range hood system provided in the embodiment can use the waste heat of the oil fume to heat the fresh air, avoid adding heating structures such as electric heating, save energy consumption, utilize and recycle the waste heat of the oil fume, and save energy.

[0034] As Figure 2As shown, based on the above embodiment, the circulation pipeline group further includes a first pipeline 6, a second pipeline 7, and a filling pipeline 8; the first pipeline 6 connects the outlet of the phase change evaporator 2 and the phase change condenser 3, and the inner cavity of the first pipeline 6 forms a first flow channel; the second pipeline 7 connects the outlet of the phase change condenser 3 and the inlet of the phase change evaporator 2, and the inner cavity of the second pipeline 7 forms a second flow channel; the filling pipeline 8 is connected to at least one of the first pipeline 6 and the second pipeline 7.

[0035] In this embodiment, the refrigerant in the phase change evaporator 2 can enter the phase change condenser 3 through the first pipe 6, and the refrigerant in the phase change condenser 3 can enter the phase change evaporator 2 through the second pipe 7, thus circulating in this manner. Refrigerant can be added to the circulation pipe group through the charging pipe 8.

[0036] The filling pipe 8 can be connected to the first pipe 6. Alternatively, the filling pipe 8 can be connected to the second pipe 7. Or, the filling pipe 8 can be connected to both the first pipe 6 and the second pipe 7.

[0037] like Figure 3 As shown, based on the above embodiments, the integrated range hood system further includes a circulation pump 9; one of the first pipe 6 and the second pipe 7 includes a first pipe section and a second pipe section, one end of the first pipe section is connected to the phase change condenser 3, the other end of the first pipe section is connected to the inlet of the circulation pump 9, one end of the second pipe section is connected to the outlet of the circulation pump 9, and the other end of the second pipe section is connected to the phase change evaporator 2.

[0038] In this embodiment, the circulation pump 9 can increase the refrigerant circulation power, and the circulation pump 9, as an auxiliary power device, makes the refrigerant circulation smoother.

[0039] The first pipeline 6 can be configured to include a first pipeline segment and a second pipeline segment that are interconnected, in which case the circulation pump 9 is connected to the first pipeline 6. Alternatively, the second pipeline 7 can be configured to include a first pipeline segment and a second pipeline segment that are interconnected, in which case the circulation pump 9 is connected to the second pipeline 7.

[0040] Specifically, the housing 1 is also provided with an exhaust vent and an air inlet for communicating with the interior, both of which are connected to the first cavity 11. An exhaust fan is installed inside the first cavity 11, and the exhaust vent can be connected to the outside through a duct (for example, connected to the kitchen's common flue through a duct). The exhaust fan exhausts the gas in the first cavity 11 to the outside and draws indoor air into the first cavity 11, thus achieving gas circulation.

[0041] like Figure 1As shown, based on the above embodiment, the housing 1 further includes an oil fume extraction chamber 14 that is isolated from both the first chamber 11 and the second chamber 12; an oil fume inlet communicating with the oil fume extraction chamber is provided on the lower front side of the housing 1, and an oil fume outlet is provided on the top of the housing 1; one end of the oil fume extraction pipe is connected to the oil fume extraction chamber, and the other end is connected to the oil fume outlet; an oil fume extraction fan is provided inside the oil fume extraction chamber 14.

[0042] In this embodiment, the fume extraction fan operates to draw the fumes from the kitchen into the fume extraction chamber 14, then sends the fumes into the fume extraction duct 4, and finally discharges them to the outside through the fume extraction outlet.

[0043] like Figure 1 As shown, based on the above embodiment, further, in the height direction of the housing 1, the fume extraction chamber 14 is located below the first chamber 11 and the second chamber 12; in the width direction of the housing 1, the first chamber 11 and the second chamber 12 are arranged side by side.

[0044] In this embodiment, the first cavity 11 and the second cavity 12 are both located above the fume extraction cavity 14. The first cavity 11 and the second cavity 12 are arranged side by side, which can make the thickness of the shell 1 smaller, thereby reducing the space occupied by the integrated range hood system in the thickness direction.

[0045] like Figure 1 As shown, based on the above embodiment, the air outlet is further opened on the front side of the housing 1, and the fresh air inlet 13 is opened on the top of the housing 1, which facilitates the connection of external pipes to the outside. The fresh air inlet is set on the top of the housing 1, so that the external pipes can be set on the top of the housing 1, avoiding occupying the thickness or width space of the integrated range hood system.

[0046] The phase change condenser 3 is located near the fresh air inlet 13, and the projection of the windward side of the phase change condenser 3 onto the plane where the fresh air inlet 13 is located can cover the fresh air inlet 13. Therefore, after the fresh air enters the second chamber 12 from the fresh air inlet 13, it will pass through the phase change condenser 3 more quickly and exchange heat more quickly. Moreover, it is beneficial to enable more fresh air to pass through the phase change condenser 3 and more fresh air to be heated.

[0047] The phase change condenser 3 can be set at an angle, ensuring that the lowest point of the phase change condenser 3 is higher than that of the phase change evaporator 2.

[0048] As an alternative, the windward side of the phase change condenser 3 is positioned directly opposite the fresh air inlet 13, that is, the phase change condenser 3 is set parallel to the fresh air inlet 13 and is set close to the fresh air inlet 13. This allows the fresh air to pass through the phase change condenser 3 immediately and completely after passing through the fresh air inlet 13, so that all the fresh air can be heated by heat exchange, thereby improving the heat exchange efficiency.

[0049] On the basis of the above-mentioned embodiments, further, the fresh air inlet 13 is provided with a filtering structure, the filtering structure can filter the fresh air entering the second cavity 12, and guarantee the cleanliness of the fresh air.

[0050] The filtering device can include a shell, a mounting cavity is formed in the shell, and a filter core is mounted in the mounting cavity, the filter core can include a filter screen, filter cotton and the like. The shell can be embedded in the fresh air inlet 13.

[0051] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and 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 present application.
