Technical Field

[0001] This application belongs to the field of air conditioning technology, and in particular relates to an oil fume filtration device and a kitchen air conditioning system. Background Technology

[0002] The kitchen is the main place where people cook, and the quality of the kitchen air environment directly affects the cooking experience. Kitchens are hot in summer and cold in winter, requiring both heating and cooling. To address this, people have invented various kitchen air conditioners to cool the air in summer and provide warm air in winter, thereby improving cooking comfort.

[0003] One type of kitchen air conditioner is linked to a range hood. By combining the kitchen air conditioner with the range hood, a kitchen air conditioning system that can remove grease and adjust the temperature is created. However, the grease exhausted from the range hood in this system can cause dirt and corrosion to the heat exchanger of the kitchen air conditioner after it enters the system. Utility Model Content

[0004] This application provides an oil fume filtration device and a kitchen air conditioning system to solve the problem that the heat exchanger of the existing kitchen air conditioning system is clogged and corroded by oil fumes.

[0005] In a first aspect, embodiments of this application provide an oil fume filtration device, which includes a collection component, a first filter component, and a second filter component. The collection component has a collection chamber for storing oil fumes, and its two ends are respectively provided with an air inlet and an air outlet communicating with the collection chamber. The first filter component is disposed at the air inlet, and the cross-sectional dimension of the first filter component gradually decreases along the direction from the air inlet to the air outlet. The second filter component is disposed at the air outlet, and the cross-sectional dimension of the second filter component gradually decreases along the direction from the air outlet to the air inlet.

[0006] Optionally, the cross-sectional profile of the first filter element is circular, elliptical, or polygonal.

[0007] Optionally, the cross-sectional profile of the second filter element is circular, elliptical, or polygonal.

[0008] Optionally, the collection chamber is provided with an adsorption material for adsorbing oil fumes.

[0009] Optionally, the fume filtration device further includes an exhaust pipe, which is connected to the collection chamber to discharge the fume inside the collection chamber.

[0010] Optionally, both the first filter and the second filter are detachably connected to the collector.

[0011] Secondly, this application also provides a kitchen air conditioning system, which includes a fume extraction device, an air conditioner, and the aforementioned fume filtration device. The exhaust port of the fume extraction device is connected to an exhaust pipe, and the heat exchanger inlet of the air conditioner is connected to a heat exchange pipe. The fume filtration device is disposed between the exhaust pipe and the heat exchange pipe, and the first filter element of the fume filtration device is connected to the exhaust pipe, and the second filter element of the fume filtration device is connected to the heat exchange pipe.

[0012] Optionally, the heat exchanger of the air conditioner includes a condenser and an evaporator, and the heat exchange tube is connected to the inlet of the condenser and the inlet of the evaporator respectively, so that the hot air in the heat exchange tube is introduced into the condenser and the evaporator respectively for heat exchange.

[0013] Optionally, the kitchen air conditioning system further includes a water heater and a heat transfer pipe, with both ends of the heat transfer pipe connected to the water heater and the heat exchange pipe, so that hot air in the heat exchange pipe is introduced into the water heater to heat the water in the water heater.

[0014] Optionally, the heat exchange tube has a first opening, a second opening, and a third opening. The first opening is connected to the second filter element, the second opening is connected to the heat medium pipe, and the third opening is connected to the heat exchanger via a connecting pipe. A valve is provided at the third opening.

[0015] The oil fume filtration device provided in this application embodiment has a first filter element whose cross-sectional size gradually decreases from the air inlet to the air outlet of the collector, and a second filter element whose cross-sectional size gradually decreases from the air outlet to the air inlet of the collector. This makes both the first and second filter elements form a constricted structure, so that the oil fume-containing air is less likely to seep back after passing through the first filter element, and the second filter element will hinder the advancement of the oil fume, allowing the oil fume to fall into the collection chamber of the collector, thereby greatly reducing the oil fume content in the air passing through the oil fume filtration device.

[0016] The kitchen air conditioning system provided in this application embodiment, by setting the above-mentioned oil fume filter device between the exhaust pipe and the heat exchange pipe, can greatly reduce the oil fume content of the air passing through it, so that the air flowing to the heat exchanger is basically oil fume-free air, thereby avoiding the problem of oil fume causing dirt blockage and corrosion to the heat exchanger.

[0025] In this application, the term "exemplary" is used to mean "used as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments.

[0026] This application provides an oil fume filtration device 100, such as... Figures 1-2 As shown, the oil fume filtration device 100 includes a collection component 110, a first filter component 120, and a second filter component 130. The collection component 110 has a collection chamber 111 for storing oil fumes. The two ends of the collection component 110 are respectively provided with an air inlet 112 and an air outlet 113 communicating with the collection chamber 111. The first filter component 120 is disposed at the air inlet 112, and the cross-sectional dimension of the first filter component 120 gradually decreases along the direction from the air inlet 112 of the collection component 110 to the air outlet 113. The second filter component 130 is disposed at the air outlet 113, and the cross-sectional dimension of the second filter component 130 gradually decreases along the direction from the air outlet 113 of the collection component 110 to the air inlet 112.

[0027] The oil fume filtration device 100 provided in this application embodiment has a first filter element 120 whose cross-sectional size gradually decreases along the direction from the air inlet 112 to the air outlet 113 of the collector 110, and a second filter element 130 whose cross-sectional size gradually decreases along the direction from the air outlet 113 to the air inlet 112 of the collector 110. This makes both the first filter element 120 and the second filter element 130 form a constricted structure. As a result, after the oil fume-containing air passes through the first filter element 120, the oil fume is not easy to seep back, and the second filter element 130 will hinder the advancement of the oil fume, so that the oil fume can fall into the collection chamber 111 of the collector 110, thereby greatly reducing the oil fume content of the air passing through the oil fume filtration device 100.

[0028] Understandably, the first filter element 120 is configured such that its cross-sectional size gradually decreases from the air inlet 112 to the air outlet 113 of the collector element 110, which is conducive to the inflow (flowing from the air inlet 112 to the air outlet 113) and collection of oil fumes, while preventing the oil fumes from flowing back (i.e., flowing from the air outlet 113 to the air inlet 112); the second filter element 130 is configured such that its cross-sectional size gradually decreases from the air outlet 113 to the air inlet 112 of the collector element 110, which can prevent the oil fumes in the collection chamber 111 from flowing out (i.e., flowing from the air outlet 113 to the air inlet 112), thus enhancing the oil fume collection effect of the collector element 110.

[0029] Optionally, the cross-sectional profile of the first filter element 120 is circular, elliptical, or polygonal (e.g., square, rectangular, trapezoidal, or triangular). For example, the first filter element 120 has a circular cross-sectional profile, and its cross-sectional dimension (i.e., cross-sectional diameter) gradually decreases from the air inlet 112 to the air outlet 113 of the collector 110, forming a constricted structure so that the oily fumes are less likely to seep back after passing through the first filter element 120. Alternatively, the first filter element 120 has a square cross-sectional profile, and its cross-sectional dimension (i.e., cross-sectional width) gradually decreases from the air inlet 112 to the air outlet 113 of the collector 110, forming a constricted structure so that the oily fumes are less likely to seep back after passing through the first filter element 120.

[0030] Optionally, the cross-sectional profile of the second filter element 130 is circular, elliptical, or polygonal (e.g., square, rectangular, trapezoidal, or triangular). For example, the cross-sectional profile of the second filter element 130 is circular, and the cross-sectional dimension (i.e., cross-sectional diameter) of the second filter element 130 gradually decreases along the direction from the air outlet 113 of the collector 110 towards the air inlet 112, so that the second filter element 130 forms a constricted structure, thereby making it difficult for oil fumes in the collection chamber 111 to pass through the second filter element 130; that is, the second filter element 130 can impede the advance of oil fumes. Alternatively, the cross-sectional profile of the second filter element 130 is square, and the cross-sectional dimension (i.e., cross-sectional width) of the second filter element 130 gradually decreases along the direction from the air outlet 113 of the collector 110 towards the air inlet 112, so that the second filter element 130 forms a constricted structure, thereby making it difficult for oil fumes in the collection chamber 111 to pass through the second filter element 130; that is, the second filter element 130 can impede the advance of oil fumes.

[0031] Optionally, both the first filter element 120 and the second filter element 130 are detachably connected to the collection element 110, so that they can be replaced when the first filter element 120 and the second filter element 130 can no longer be used, in order to ensure the filtration effect.

[0032] In some embodiments of this application, the collection chamber 111 is provided with an adsorbent material 140 for adsorbing oil fumes, thereby improving purification efficiency by adsorbing oil fumes in the air entering the collection chamber 111. Optionally, the adsorbent material 140 can be porous activated carbon, sponge, or other materials that can effectively adsorb oil fumes.

[0033] In some embodiments of this application, the fume filter device 100 further includes an exhaust pipe 150, which is connected to the collection chamber 111 to discharge the fumes in the collection chamber 111. That is, the fumes in the collection chamber 111 are discharged to the outside of the fume filter device 100 through the exhaust pipe 150, so as to prevent the collection chamber 111 from having too much fumes and being unable to continue to be effectively filtered and collected.

[0034] This application also provides a kitchen air conditioning system, such as... Figure 3 As shown, the kitchen air conditioning system includes a fume extraction device, an air conditioner, and a fume filter 100. The specific structure of the fume filter 100 is as described in the above embodiment. The exhaust port of the fume extraction device is connected to an exhaust pipe 210, and the heat exchanger inlet of the air conditioner is connected to a heat exchange pipe 220. The fume filter 100 is disposed between the exhaust pipe 210 and the heat exchange pipe 220, and the first filter element 120 of the fume filter 100 is connected to the exhaust pipe 210, and the second filter element 130 of the fume filter 100 is connected to the heat exchange pipe 220.

[0035] The kitchen air conditioning system provided in this application embodiment uses the aforementioned oil fume filter 100 installed between the exhaust pipe 210 and the heat exchange pipe 220. This allows the oil-fume-laden air discharged from the exhaust pipe 210 to be filtered by the oil fume filter 100 before entering the heat exchange pipe 220. The oil fume filter 100 can greatly reduce the oil fume content of the air passing through it, making the air flowing to the heat exchanger basically oil-fume-free, thereby avoiding the problem of oil fume causing dirt blockage and corrosion to the heat exchanger.

[0036] Since this kitchen air conditioning system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0037] In some embodiments of this application, the heat exchanger of the air conditioner includes a condenser 230 and an evaporator 240, and a heat exchange tube 220 is connected to the inlet of the condenser 230 and the inlet of the evaporator 240 respectively, so that the hot air in the heat exchange tube 220 is passed into the condenser 230 and the evaporator 240 respectively for heat exchange.

[0038] In other embodiments, the heat exchanger of the air conditioner may also include only an evaporator 240, with a heat exchange tube 220 connected to the inlet of the evaporator 240 so that heat exchange occurs in the hot air evaporator 240 within the heat exchange tube 220.

[0039] In some embodiments of this application, the kitchen air conditioning system further includes a water heater 250 and a heat transfer pipe 260. The two ends of the heat transfer pipe 260 are connected to the water heater 250 and a heat exchange pipe 220, allowing hot air from the heat exchange pipe 220 to be introduced into the water heater 250 to heat the water in the water heater 250. The oil fume filter 100 can effectively filter the oil-containing air discharged from the exhaust pipe 210, preventing oil fumes from flowing towards the water heater 250, evaporator 240, and condenser 230, thus avoiding clogging and corrosion.

[0040] Optionally, the heat exchange tube 220 has a first opening, a second opening, and a third opening. The first opening is connected to the second filter element 130, allowing air filtered by the oil fume filter device 100 to enter the heat exchange tube 220 through the first opening. The second opening is connected to the heat medium pipe 260, allowing air in the heat exchange tube 220 to enter the water heater 250 through the heat medium pipe 260 for heat exchange. The third opening is connected to the heat exchanger through a connecting pipe 270. A valve 280 is provided at the third opening, which is used to open or close the third opening. When the valve 280 is open, air in the heat exchange tube 220 can enter the heat exchanger through the connecting pipe 270 for heat exchange. When the valve 280 is closed, air in the heat exchange tube 220 cannot enter the heat exchanger. Specifically, when the heat exchanger includes a condenser 230 and an evaporator 240, the third opening of the heat exchange tube 220 is connected to the evaporator 240 and the condenser 230 respectively through two connecting pipes 270.

[0041] Specifically, the air filtered by the fume filter 100 can flow into the water heater 250, condenser 230, and evaporator 240. When the indoor temperature is low and heating is required, valve 280 is opened to allow the filtered air to simultaneously flow into the evaporator 240, condenser 230, and water heater 250 for heat exchange. This preheats the air inlet temperature of the condenser 230 and increases the outlet temperature of the indoor air vents, thereby improving the heating efficiency of the air conditioning system. Furthermore, as the filtered air flows through the water heater 250, it appropriately heats the water in the water heater 250, thus providing domestic hot water to a certain extent. When the indoor temperature is high and cooling is required, valve 280 is closed to restrict the flow of filtered air into the evaporator 240 and condenser 230, avoiding unnecessary energy consumption. Only the filtered air is allowed to flow into the water heater 250 to appropriately heat the water in the water heater 250 and then promptly discharge it. This kitchen air conditioning system effectively combines a fume extractor, an air conditioner, and a water heater 250. While properly solving the cooling and heating problems in the high-fume environment of the kitchen, it converts the waste heat of the flue air into a heat source for hot water and air conditioning, achieving high efficiency, energy saving, and cleanliness of the kitchen air conditioning system.
