Description

[0002] In the related art, the range hood removes the oil fume generated in the cooking process in a relatively simple way, that is, through the oil fume filter screen arranged at the entrance of the flue to filter the oil fume, or through the high-speed rotating range hood fan to throw off the oil fume.

[0003] Generally, in order to filter a sufficient amount of oil fume, the oil fume filter screen generally adopts a design with low porosity, that is, a relatively dense filter screen is used.

If the filter screen is not used, and the high-speed rotating range hood fan is used to throw off the oil fume, part of the oil fume will accumulate in the range hood fan, thereby causing the range hood fan to slow down, the air volume to decrease, and the oil fume pollutants to accumulate in the fan volute and be unable to be cleaned.

[0031] DETAILED DESCRIPTION

[0032] It should be noted that the embodiments in the present application and the technical features in the embodiments can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as the explanation and description of the purpose of the present application, and should not be regarded as improper limitation of the present application.

[0033] An embodiment of the present application provides a condensate collecting device 10 for an extractor hood, please refer to Figure 1 and Figure 2 The condensate collecting device 10 includes an oil-water collecting assembly 11 and a cooling assembly 12; the cooling assembly 12 cools the oil-water collecting assembly 11, so that the airflow flowing through the oil-water collecting assembly 11 is condensed at the oil-water collecting assembly 11.

[0034] Another embodiment of the present application provides an extractor hood, please refer to Figure 1 ​​​​​The oil fume collector comprises a flue 20 and the condensation collecting device 10 of any embodiment of the present application, and the oil-water collecting assembly 11 is arranged on the airflow flow path in the flue 20.

[0035] Specifically, refer to Figure 1 During cooking, the flue fan 50 of the oil fume collector drives the airflow to flow, so that a negative pressure is generated in the flue 20, thereby the airflow can be sucked into the flue 20. Since the temperature above the cooking top is relatively high, a part of the oil fume and water vapor is mixed in the airflow before being sucked into the flue 20. After the airflow mixed with the oil fume and water vapor is sucked into the flue 20, the airflow flows along the airflow flow path in the flue 20. Since the cooling assembly 12 cools the oil-water collecting assembly 11 arranged on the airflow flow path, the temperature of the oil-water collecting assembly 11 is relatively low. When the airflow flows through the oil-water collecting assembly 11, the airflow contacts the oil-water collecting assembly 11 with relatively low temperature and condensation occurs at the oil-water collecting assembly 11. Thus, the oil fume mixed in the airflow can be condensed into grease, and the water vapor can be condensed into condensed water. That is, the condensation collecting device 10 of the present application can rapidly condense the oil fume and water vapor into grease and condensed water by cooling the oil-water collecting assembly 11 with the cooling assembly 12, thereby greatly improving the collection efficiency of the oil fume and water vapor, and further improving the oil fume removal rate of the oil fume collector.

[0036] The condensation collecting device 10 of the present application can not need to arrange a filter screen with high density in the flue 20, thereby avoiding the problems that the filter screen with high density affects the air volume of the oil fume collector, and the filter screen is easily blocked after accumulating the oil fume. Meanwhile, the problems that the oil fume accumulates in the flue fan 50 of the oil fume collector to cause the flue fan 50 to slow down, the air volume to decrease, and the oil fume dirt to accumulate in the fan volute and cannot be cleaned can be greatly avoided.

[0037] The cooling assembly 12 of the embodiment of the present application can be any assembly capable of cooling the oil-water collecting assembly 11. In an embodiment, the cooling assembly 12 can be a cooling coil. The cooling coil is cooled by the coolant flowing into the cooling coil from the inlet of the cooling coil, absorbing the heat of the oil-water collecting assembly 11 in the cooling coil, and then flowing out of the outlet of the cooling coil, thereby cooling the oil-water collecting assembly 11.

[0038] In another embodiment, the cooling assembly 12 can be a semiconductor sheet. The semiconductor sheet mainly absorbs the heat of the oil-water collecting assembly 11 at the cold end of the semiconductor sheet in the electrified state, and releases the heat at the hot end of the semiconductor sheet, thereby cooling the oil-water collecting assembly 11.

[0039] In addition to the cooling coil and the semiconductor sheet, the cooling assembly 12 can be other components capable of achieving the cooling function, and the specific arrangement position of the cooling assembly 12 can be adjusted as needed, as long as the oil-water collecting assembly 11 can be cooled.

[0040] In an embodiment, referring to Figures 1 to 4 , the oil-water collecting assembly 11 comprises a first filter 111 having an airflow outlet 111a, and the airflow flowing through the oil-water collecting assembly 11 collides with the first filter 111, so that the airflow is condensed on the first filter 111.

[0041] Specifically, since the cooling assembly 12 cools the oil-water collecting assembly 11, the temperature of the first filter 111 is relatively low. When the airflow containing oil fume and water vapor flows through the first filter 111, the airflow collides with the first filter 111 which has a relatively low temperature, and the first filter 111 condenses the airflow by using its relatively low temperature, so that the oil fume and water vapor in the airflow can be quickly condensed into grease and condensed water, and the airflow from which the grease and condensed water are condensed and separated flows out from the airflow outlet 111a.

[0042] In addition, the airflow before condensation usually contains some liquid droplets formed by the liquefaction of oil fume and water vapor, so when the airflow collides with the first filter 111, the liquid droplets contained in the airflow are also intercepted by the first filter 111.

[0043] In an embodiment, referring to Figures 1 to 6 , the oil-water collecting assembly 11 further comprises a second filter 112 having an airflow inlet 112a; the second filter 112 and the first filter 111 define an oil-water collecting space 11a therebetween, the airflow inlet 112a and the airflow outlet 111a are both in communication with the oil-water collecting space 11a, and at least part of the airflow inlet 112a is staggered with the airflow outlet 111a.

[0044] Specifically, the second filter 112 and the first filter 111 can be connected with each other or arranged separately, as long as the second filter 112 and the first filter 111 can define the oil-water collecting space 11a therebetween, and at least part of the airflow inlet 112a is staggered with the airflow outlet 111a.

[0045] The airflow enters the oil-water collecting space 11a from the airflow inlet 112a and flows out from the airflow outlet 111a. Since at least part of the airflow inlet 112a is staggered with the airflow outlet 111a, at least part of the airflow entering the oil-water collecting space 11a collides with the first filter 111 before flowing out from the airflow outlet 111a, and is condensed on the first filter 111 to form grease and condensed water, so that the oil fume and water vapor contained in the airflow can be separated.

[0046] The air flow inlet 112a on the second filter 112 can focus the air flow so that the air flow can hit the first filter 111 more accurately. The oil and water collecting space 11a is defined between the second filter 112 and the first filter 111, which can facilitate the collection of the oil and condensed water formed on the first filter 111. In addition, the air flow can hit the second filter 112 and form part of the oil and condensed water on the second filter 112 before entering the oil and water collecting space 11a. That is, the second filter 112 can play a role of primary filtration, thereby improving the oil fume removal rate.

[0047] In an embodiment, referring to Figures 4 to 6 The second filter 112 has a plurality of air flow inlets 112a arranged at intervals, and the first filter 111 has a plurality of air flow outlets 111a arranged at intervals. The plurality of air flow inlets 112a and the plurality of air flow outlets 111a are staggered with each other.

[0048] That is, when the second filter 112 has a plurality of air flow inlets 112a arranged at intervals and the first filter 111 has a plurality of air flow outlets 111a arranged at intervals, each air flow inlet 112a on the second filter 112 can be directed to the interval between each adjacent two air flow outlets 111a on the first filter 111, or each air flow outlet 111a on the first filter 111 can be directed to the interval between each adjacent two air flow inlets 112a on the second filter 112.

[0049] The second filter 112 has a plurality of air flow inlets 112a arranged at intervals, and the first filter 111 has a plurality of air flow outlets 111a arranged at intervals. The plurality of air flow inlets 112a and the plurality of air flow outlets 111a are staggered with each other, which can make the air flow entering the oil and water collecting space 11a hit the first filter 111 as much as possible, thereby improving the air flow rate and further improving the oil fume removal rate.

[0050] In an embodiment, referring to Figure 5, the airflow inlet 112a is long and narrow, so that the airflow hitting the first filter 111 can be more accurately controlled, and in addition, when the liquid droplets mixed in the airflow hit the first filter 111, only part of the liquid droplets can be intercepted by the first filter 111, and a small amount of liquid droplets will still flow out of the airflow outlet 111a on the first filter 111 with the airflow, and by setting the airflow inlet 112a to be long and narrow, the size of the liquid droplets intercepted by the first filter 111 can be controlled, that is, the long and narrow airflow inlet 112a cooperates with the first filter 111 to enable the first filter 111 to intercept a part of the liquid droplets with relatively large particle size, and only allow a part of the liquid droplets with relatively small particle size to flow out of the airflow outlet 111a on the first filter 111 with the airflow, thereby improving the filtering effect of the first filter 111.

[0051] In actual use, the size of the liquid droplets intercepted by the first filter 111 can be controlled by controlling the width of the long and narrow airflow inlet 112a on the second filter 112, for example, please refer to Figure 5 When the width H of the airflow inlet 112a is 5-50mm, the first filter 111 can intercept liquid droplets with a particle size of at least 10 microns.

[0052] In addition, in actual use, the number of airflow inlets 112a on the second filter 112 and the length of each airflow inlet 112a can be determined according to the exhaust flow of the range hood fan 50 and the width of the airflow inlet 112a on the second filter 112, for example, the exhaust flow of the range hood fan 50 can be 800-1800 cubic meters per hour, that is, 800-1800m 3 / h, and the width H of the airflow inlet 112a is 5-50mm, and in design, the number of airflow inlets 112a and the length of each airflow inlet 112a can be further determined according to the selected exhaust flow of the range hood fan 50 and the width of the airflow inlet 112a, for example, when the exhaust flow of the range hood fan 50 is 1200 cubic meters per hour and the width H of the airflow inlet 112a is 10mm, 20 airflow inlets 112a can be provided on the second filter 112, and the length of each airflow inlet 112a can be 198mm.

[0053] In some embodiments, the shape of the airflow inlet 112a can also be waist-shaped, circular, rectangular, triangular, irregular, etc., as long as the airflow can flow into the oil-water collection space 11a from the airflow inlet 112a.

[0054] Similarly, the shape of the airflow outlet 111a on the first filter 111 can also be long and narrow, waist-shaped, circular, rectangular, triangular, irregular, etc., as long as the airflow can flow out of the oil-water collection space 11a from the airflow outlet 111a.

[0055] In addition, it should be noted that the size of the air flow outlet 111a on the first filter 111 is not particularly required, as long as the air flow can flow out of the oil-water collection space 11a from the air flow outlet 111a

[0056] In some embodiments, only the first filter 111 can be provided without the second filter 112.

[0057] In an embodiment, referring to Figures 1 to 3 The cooling assembly 12 is arranged on the side of the first filter 111 away from the second filter 112, so that the cooling assembly 12 can sufficiently cool the first filter 111, thereby improving the condensation effect of the first filter 111 on the air flow.

[0058] In an embodiment, the condensation and collection device 10 further comprises an elastic member, and the cooling assembly 12 is pressed against the first filter 111 under the elastic force of the elastic member.

[0059] Specifically, the elastic member can be a spring, a spring sheet, a buckle with elasticity, or the like. By being pressed against the first filter 111 under the elastic force of the elastic member, the cooling assembly 12 can be in sufficient contact with the first filter 111, thereby enhancing the heat conduction between the cooling assembly 12 and the first filter 111, so that the first filter 111 can be more sufficiently cooled, and the condensation effect of the first filter 111 on the air flow can be further improved.

[0060] In an embodiment, referring to Figures 1 to 3 The oil-water collection assembly 11 is arranged obliquely in the flue 20 to form an oil-water flow path on the oil-water collection assembly 11, that is, the grease and condensed water condensed at the oil-water collection assembly 11 can flow along the oil-water flow path, thereby facilitating the discharge of the grease and condensed water.

[0061] In an embodiment, referring to Figures 1 to 3 The extractor hood further comprises an oil-water collection box 30, which is in communication with the end of the oil-water flow path, that is, the grease and condensed water flowing along the oil-water flow path can flow into the oil-water collection box 30, thereby facilitating the user to clean the grease and condensed water discharged from the oil-water collection assembly 11 in time.

[0062] In an embodiment, the oil-water collection assembly 11 is detachably arranged in the flue 20, thereby facilitating the disassembly and cleaning of the oil-water collection assembly 11.

[0063] Exemplarily, taking the oil-water collection assembly 11 with the first filter 111 and the second filter 112 as an example, the first filter 111 and the second filter 112 can be detachably arranged in the flue 20 respectively, and the first filter 111 and the second filter 112 can also be detachably connected, which is equivalent to that the first filter 111 and the second filter 112 are connected and then arranged in the flue 20 as a whole structure. The first filter 111 and the second filter 112 of the embodiment of the present application are simple in structure and have no dead angle, and can be conveniently cleaned.

[0064] In an embodiment, referring to Figures 1 to 3 , the flue 20 can also be provided with a filter screen 40 on the airflow flow path, and the filter screen 40 is located upstream of the oil-water collection assembly 11 in the airflow flow direction, that is, the airflow can first flow through the filter screen 40 for filtration and then flow through the oil-water collection assembly 11.

[0065] The filter screen 40 can be selected from a filter screen with relatively low density, for example, a filter screen with a resistance less than or equal to 100 Pa, to intercept liquid droplets with a large particle size, so as to improve the filtration effect, avoid affecting the air volume of the range hood, and also avoid the filter screen 40 from being blocked.

[0066] In some embodiments, the filter screen 40 can also not be arranged.

[0067] In an embodiment, referring to Figure 1 , the range hood is an air-conditioning range hood, and the air-conditioning range hood includes an air-conditioning unit 60. The cooling assembly 12 is a cooling coil, and the pipeline in the cooling coil is in communication with the pipeline of the air-conditioning unit 60.

[0068] Specifically, referring to Figure 1 , similar to the structure of the air conditioner, the air-conditioning range hood also has a condenser 61, a compressor 62, an evaporator 63, a throttling valve 64, an air-conditioning fan 65 and other components. During the cooking process, the air-conditioning unit 60 is in a refrigeration mode, so as to reduce the temperature of the surrounding environment, so that the cooking process is more comfortable.

[0069] For example, the oil-water collecting assembly 11 with the first filter 111 and the second filter 112, the cooling coil can be arranged on the side of the first filter 111 away from the second filter 112 and in contact with the first filter 111, and the pipeline in the cooling coil is in communication with the pipeline of the air conditioning unit 60. When the air conditioning unit 60 performs the refrigeration operation, the refrigerant flows from the pipeline of the air conditioning unit 60 into the cooling coil to cool the first filter 111, and the refrigerant absorbing heat at the first filter 111 flows back to the pipeline of the air conditioning unit 60. That is, the cooling coil connected with the air conditioning unit 60 of the air conditioning unit itself can cool the oil-water collecting assembly 11. Therefore, other refrigeration equipment does not need to be arranged for the cooling assembly 12, which saves the cost and is convenient for installation and manufacturing.

[0070] It can be understood that in some embodiments, the cooling coil can also be separately arranged with the refrigeration equipment similar to the function of the air conditioning unit 60.

[0071] The various embodiments / implementation modes provided in the present application can be combined with each other without contradiction.

[0072] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application is included in the protection scope of the present application.
