Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, specifically to an oil stain cleaning device, an air conditioner range hood, and a method for cleaning oil stains with condensate water. Background Technology

[0002] An air-conditioning range hood is a kitchen appliance that integrates the cooling function of an air conditioner with the fume extraction function of a range hood. It effectively solves the pain points of high temperatures and greasy fumes in the kitchen during summer. As a heat exchange device in the kitchen, an air-conditioning range hood inevitably produces condensation during cooling. Unlike traditional air conditioners, which can drain condensation outdoors via ducts, air-conditioning range hoods, being multifunctional appliances, have a complex internal structure and specific installation requirements. Therefore, they cannot drain condensation outdoors via ducts like traditional air conditioners. Furthermore, the limited internal space of an air-conditioning range hood cannot hold excessive condensation. When too much condensation accumulates, it leaks through gaps in the sheet metal, potentially causing short circuits in electronic components and resulting in a poor user experience.

[0003] Some air conditioner range hood manufacturers use technologies such as atomizers and evaporators to turn condensate into water vapor before discharging it outdoors through flues. However, the layout and length of these flues significantly impact water vapor discharge, causing some condensate to flow back into the range hood, affecting its normal operation. Therefore, effectively and properly handling condensate from air conditioner range hoods is crucial. Summary of the Invention

[0004] In view of this, the present invention provides an oil stain cleaning device, an air conditioner range hood, and a method for cleaning oil stains with condensate water, so as to solve the problem of the inability to properly handle the condensate water generated by the air conditioner range hood.

[0005] In a first aspect, the present invention provides an oil stain cleaning device for an air conditioner range hood, comprising:

[0006] The condensate storage chamber has a condensate inlet, a condensate outlet, and a pressurized airflow inlet, wherein the condensate inlet is adapted to be connected to the condensate drip tray of the air conditioning module of the air conditioning range hood;

[0007] A cleaning pipe, wherein the inlet of the cleaning pipe is connected to the condensate outlet, and the outlet of the cleaning pipe is adapted to be connected to the fan impeller of the range hood module of the air conditioner range hood;

[0008] The pressurization chamber has an air inlet and a pressurized airflow outlet. The air inlet is adapted to communicate with the hot air channel of the air conditioning module of the air conditioning range hood. The pressurized airflow outlet is connected to the pressurized airflow inlet through a pressurization pipe. A pressurization device is provided inside the pressurization chamber.

[0009] Beneficial effects: The condensate storage chamber collects condensate from the air conditioning module of the range hood. The pressurizing device in the pressurizing chamber pressurizes the hot air delivered from the hot air duct of the air conditioning module and connects the pressurized hot air to the condensate in the condensate storage chamber through a pressurizing pipe, forming high-pressure condensate. This high-pressure condensate is then transported through a cleaning pipe to the range hood impeller and sprayed out to wash away grease stains. This grease cleaning device of the present invention, on the one hand, properly handles the condensate from the air conditioning module, avoiding the inconvenience caused by condensate leakage and backflow; on the other hand, it utilizes the condensate and the hot air from the hot air duct of the air conditioning module to clean the range hood impeller, improving the user experience.

[0010] In one optional embodiment, the oil stain cleaning device includes a housing, a condensate storage chamber and a pressurization chamber formed within the housing; the condensate inlet is located at the upper part of the housing, the condensate outlet is located at the bottom of the housing, the air inlet is located at the top of the housing, and the pressurized airflow outlet is correspondingly located at the bottom of the housing.

[0011] Beneficial effects: The condensate inlet is located at the top of the housing, allowing water in the condensate drip tray to flow from the condensate inlet to the condensate storage chamber by gravity; the range hood module is located below the air conditioning module, and the condensate outlet is located at the bottom of the housing, facilitating the transport of condensate and reducing transport resistance; the air inlet is located at the top of the housing, facilitating the guidance of hot air from the hot air channel to the pressurization chamber; the pressurized airflow outlet is located at the bottom of the housing, facilitating the direct exhaust of airflow from the top air inlet from the bottom, resulting in low airflow resistance and energy savings.

[0012] In one optional embodiment, the pressurizing device includes a motor and a pressurizing impeller, the pressurizing impeller being disposed between the air inlet and the pressurized air outlet, and the pressurizing impeller being drivenly connected to the output shaft of the motor.

[0013] Beneficial effects: The pressurized impeller is located between the air inlet and the pressurized air outlet, with air intake at the top and air outlet at the bottom, resulting in low loss and a compact structure.

[0014] In one alternative embodiment, the cleaning pipe is bent to form a horizontal spray section.

[0015] Beneficial effects: The outlet of the horizontal spray section is set towards the smoke machine impeller, which allows the water flow to vertically wash the smoke machine impeller, resulting in a strong impact and thorough cleaning.

[0016] Secondly, the present invention also provides an air conditioning range hood, including an air conditioning module, a range hood module, and any of the above-described oil stain cleaning devices.

[0017] Beneficial effects: Since the air conditioner range hood includes the oil stain cleaning device of the present invention, it has the same effect as the oil stain cleaning device, which will not be described in detail here.

[0018] In one optional embodiment, the air conditioning module includes a condensate drip tray, a cold air passage, and a hot air passage. The condensate drip tray is connected to the condensate storage chamber via a condensate drain pipe. The air inlet of the pressurization chamber is connected to the hot air passage.

[0019] Beneficial effects: The condensate collected in the condensate drip tray is transported to the condensate storage chamber of the oil stain cleaning device through the condensate guide pipe. The hot air introduced into the pressurization chamber through the hot air channel is pressurized and then used as the driving airflow to be transported to the condensate storage chamber. The condensate is pressurized and transported to the range hood impeller for use. The condensate from the air conditioning module is effectively used to flush and clean the range hood impeller, and then carries the oil stains into the oil cup.

[0020] In one alternative implementation, the air inlet is located on one side of the hot air duct.

[0021] Beneficial effects: The air inlet is located on one side of the hot air duct, allowing hot air to be directly introduced into the air inlet without the need for additional delivery pipes.

[0022] In one optional embodiment, the oil stain cleaning device is disposed between the condensate drip tray and the range hood module.

[0023] Beneficial effects: The oil stain cleaning device is located between the condensate water receiving tray and the range hood module, which facilitates the introduction of condensate water into the oil stain cleaning device, which is then pressurized and delivered to the range hood impeller for cleaning, ensuring a smooth connection.

[0024] In one optional embodiment, the range hood module includes a volute, a range hood impeller, and an oil cup, with the water outlet of the cleaning pipe located at the range hood impeller.

[0025] Beneficial effects: After the oil stain cleaning device uses condensate water to clean the range hood impeller, the condensate water carrying the oil stains falls into the oil cup, making it convenient for users to empty.

[0026] Thirdly, the present invention also provides a method for cleaning grease stains from the condensate water of an air conditioner range hood based on any of the above-described methods, the method comprising the following steps:

[0027] When the air conditioning module is activated, condensate enters the condensate storage chamber of the oil stain cleaning device.

[0028] When the oil stain cleaning device is started, the hot air in the hot air duct enters the pressurization chamber through the air inlet, is pressurized, and then connected to the condensate storage chamber through the pressurization pipe. The condensate is transported to the outlet of the cleaning pipe under the action of the pressurized airflow and sprayed out to clean the fan impeller of the range hood.

[0029] Beneficial effects: The condensate from the air conditioning module of the range hood is used to clean the fan impeller of the range hood module. This effectively utilizes the condensate and removes grease, greatly improving the user experience of the range hood and enhancing the product's competitiveness.

[0030] In one alternative implementation, the air conditioning module is activated simultaneously with the activation of the oil stain cleaning device.

[0031] Beneficial effects: The oil stain cleaning device and the air conditioning module are started simultaneously, and the condensate water generated when the air conditioner is working is discharged and utilized in time. Attached Figure Description

[0064] The following is combined with Figures 1 to 10 The following describes embodiments of the present invention.

[0065] According to an embodiment of the present invention, in one aspect, such as Figure 2 , Figure 3 and Figure 5 As shown, an oil stain cleaning device 2 for an air conditioner range hood is provided, comprising:

[0066] The condensate storage chamber 24 has a condensate inlet 28, a condensate outlet and a pressurized airflow inlet 231. The condensate inlet 28 is adapted to be connected to the condensate drip tray 1 of the air conditioning module of the air conditioning range hood.

[0067] Cleaning pipe 21, the inlet of cleaning pipe 21 is connected to the condensate outlet, and the outlet of cleaning pipe 21 is adapted to be connected to the range hood impeller 3 of the range hood module of the air conditioner range hood.

[0068] The pressurized chamber has an air inlet 22 and a pressurized air outlet 25. The air inlet 22 is adapted to be connected to the hot air channel 13 of the air conditioning module of the air conditioning range hood. The pressurized air outlet 25 is connected to the pressurized air inlet 231 through the pressurized pipe 23. A pressurizing device is installed inside the pressurized chamber.

[0069] The condensate storage chamber 24 collects condensate from the air conditioning module of the range hood. The pressurizing device in the pressurizing chamber pressurizes the hot air delivered from the hot air duct 13 of the air conditioning module and connects the pressurized hot air to the condensate storage chamber 24 via the pressurizing pipe 23, forming high-pressure condensate. This high-pressure condensate is then delivered to the range hood impeller 3 via the cleaning pipe 21 and sprayed out to wash away grease on the impeller 3. The grease cleaning device 2 of this invention not only properly handles the condensate from the air conditioning module, avoiding the inconvenience caused by condensate leakage and backflow, but also effectively utilizes the condensate, using both the condensate and the hot air from the hot air duct 13 of the air conditioning module to clean the range hood impeller 3, thus improving the user experience.

[0070] In one alternative implementation, such as Figure 4 As shown, the oil stain cleaning device 2 includes a housing, a condensate storage chamber 24 and a pressurization chamber formed inside the housing, and the condensate storage chamber 24 and the pressurization chamber are two independent chambers; the condensate inlet 28 is located at the upper part of the housing, corresponding to the position of the condensate storage chamber 24, the condensate outlet is located on the housing corresponding to the bottom of the condensate storage chamber 24, the air inlet 22 is located at the top of the housing corresponding to the pressurization chamber, and the pressurized airflow outlet 25 is correspondingly located at the bottom of the housing.

[0071] The condensate inlet 28 is located at the top of the housing, allowing water in the condensate drip tray 1 to flow by gravity from the condensate inlet 28 into the condensate storage chamber 24. The range hood module is located below the air conditioning module, and the condensate outlet is located at the bottom of the housing, facilitating the transport of condensate and reducing transport resistance. The air inlet 22 is located at the top of the housing, facilitating the guidance of hot air in the hot air channel 13 to the pressurization chamber. The pressurized airflow outlet 25 is located at the bottom of the housing, facilitating the direct exhaust of airflow entering from the top air inlet 22 from the bottom, resulting in low airflow resistance and energy savings.

[0072] In one optional embodiment, the pressurizing device includes a motor 27 and a pressurizing impeller 26, the pressurizing impeller 26 being disposed between the air inlet 22 and the pressurized air outlet 25, and the pressurizing impeller 26 being drivenly connected to the output shaft of the motor 27.

[0073] The pressurized impeller 26 is positioned between the air inlet 22 and the pressurized air outlet 25, with air intake at the top and exhaust at the bottom, resulting in low energy loss and a compact structure. A motor 27 drives the pressurized impeller 26 to rotate, generating negative pressure. This pressure conveniently draws hot air from the hot air duct 13 of the air conditioning module into the pressurized chamber, and then delivers it to the condensate storage chamber 24 to pressurize and transport the condensate. This enables high-pressure hot water cleaning of components such as the range hood impeller 3 of the range hood module. The range hood impeller 3 cannot be disassembled, offering high convenience.

[0074] In one alternative implementation, such as Figures 1-3 , Figure 5 and Figure 6 As shown, the cleaning pipe 21 is bent at the bottom to form a horizontal spray section.

[0075] The outlet of the horizontal spray section is set towards the smoke machine impeller 3, which allows the high-pressure water flow to vertically wash the smoke machine impeller 3, resulting in a large impact force and thorough cleaning.

[0076] According to an embodiment of the present invention, in another aspect, the present invention also provides an air conditioning range hood, including an air conditioning module, a range hood module, and an oil stain cleaning device 2.

[0077] Because the air-conditioning range hood includes the oil stain cleaning device 2 of this invention, it can effectively utilize the condensate discharged from the air conditioning module, and in conjunction with the heat dissipation airflow of the air conditioning module, form high-pressure condensate that is delivered to the range hood module for cleaning. This not only eliminates the need for an additional condensate drainage channel, but also achieves oil stain cleaning, improves user satisfaction and product competitiveness, and creates conditions for the widespread promotion of air-conditioning range hoods.

[0078] In one optional embodiment, the air conditioning module includes a condensate collection tray 1 serving as an air conditioning chassis, as well as a cold air passage and a hot air passage 13. The condensate collection point 11 of the condensate collection tray 1 is connected to the condensate storage chamber 24 through a condensate guide pipe 12, and the air inlet 22 of the pressurized chamber is connected to the hot air passage 13.

[0079] The condensate collected in the condensate drip tray 1 is transported to the condensate storage chamber 24 of the oil stain cleaning device 2 through the condensate guide pipe 12. The hot air introduced into the pressurization chamber through the hot air channel 13 is pressurized and then used as the driving airflow to be transported to the condensate storage chamber 24. The condensate is pressurized and transported to the range hood impeller 3 for use. The condensate from the air conditioning module is effectively used to flush and clean the range hood impeller 3, and then carries the oil stains into the oil cup 5.

[0080] It should be noted that oil cup 5 can be emptied when it is full. Multiple tests on the test sample showed that the amount of condensate produced by the air conditioning module in a single use is not large enough to fill oil cup 5 completely in one go; when the air conditioning module is used frequently, it takes about 15 days for oil cup 5 to fill with condensate. When the temperature is low or the air is dry, it will take even longer to empty the condensate.

[0081] In one alternative implementation, such as Figure 7 and Figure 8 As shown, the air inlet 22 of the oil stain cleaning device 2 is located on one side of the hot air channel 13.

[0082] The air inlet 22 is located on one side of the hot air channel 13. Hot air can be directly introduced into the pressurization chamber from the air inlet 22 without the need for additional delivery pipes. The structure is compact and reasonable.

[0083] In one alternative implementation, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 9 As shown, the oil stain cleaning device 2 is installed between the condensate water receiving pan 1 and the flue fan impeller 3.

[0084] The oil stain cleaning device 2 is located between the condensate water receiving pan 1 and the range hood impeller 3, which facilitates the introduction of condensate water into the oil stain cleaning device 2, which is then pressurized and transported to the range hood impeller 3 for cleaning, ensuring a smooth connection. Moreover, the flow of condensate water can also rely on gravity, saving transmission energy.

[0085] In one optional embodiment, the range hood module includes a baffle plate, a volute 4, a range hood impeller 3, and an oil cup 5, with the water outlet of the cleaning pipe 21 located at the range hood impeller 3.

[0086] The outlet of the cleaning pipe 21 is located at the fan impeller 3 of the range hood for easy cleaning; after the oil stain cleaning device 2 cleans the fan impeller 3 with condensate water, the condensate water carrying the oil stains falls into the oil cup 5 for easy emptying by the user.

[0087] In a preferred embodiment of the present invention, the air-conditioning range hood includes an oil stain cleaning device 2, a volute 4, a range hood impeller 3, a condensate drip tray 1, and the entire range hood unit. When the air conditioning module is in cooling mode, the generated condensate drips onto the air conditioning module's drip tray. Under the action of gravity, the condensate collects at the condensate collection point 11, and the collected condensate flows through the condensate guide pipe 12 to the condensate storage chamber 24 of the oil stain cleaning device 2. The hot air generated by the air conditioning range hood during cooling is drawn into the range hood unit by the negative pressure created within the volute 4 of the range hood module. The high-pressure hot air from the air conditioning system enters the interior of the air-conditioning range hood through the hot air channel 13 of the air conditioning module. The air inlet 22 of the oil stain cleaning device 2 is located on one side of the hot air channel 13, which serves as a heat dissipation channel. When the motor 27 inside the oil stain cleaning device 2 drives the pressure impeller 26 to rotate, the hot airflow on the hot air channel 13 is continuously drawn into the oil stain cleaning device 2. The oil stain cleaning device 2 then heats the air... After the airflow is pressurized, it is sent to the condensate storage chamber 24 through the pressurization pipe 23. High pressure and heat are generated inside the condensate storage chamber 24. The pressurized condensate is finally delivered to the range hood impeller 3 through the cleaning pipe 21 and sprayed onto the range hood impeller 3. The pressurized and heated condensate effectively cleans the oil stains accumulated on the range hood impeller 3. The heat of the hot airflow in the hot air passage 13 is effectively transferred to the condensate. The condensate with temperature after absorbing the heat of the hot air effectively melts the oil stains on the range hood impeller 3, reducing the difficulty of cleaning the impeller.

[0088] This invention solves the problems of condensate treatment in air conditioning range hoods and heat dissipation in air conditioning modules. It makes full use of the condensate and the hot airflow generated by the air conditioning module to clean the range hood impeller 3 of the range hood module. The utilization of the hot airflow improves the heat dissipation efficiency of the air conditioning module to a certain extent, and effectively improves the energy exchange efficiency of the air conditioning module.

[0089] According to an embodiment of the present invention, in another aspect, the present invention also provides a method for cleaning grease stains using condensate water from an air conditioner range hood, the method comprising the following steps:

[0090] When the air conditioning module is activated, condensate enters the condensate storage chamber 24 of the oil stain cleaning device 2;

[0091] When the oil stain cleaning device 2 is started, the hot air in the hot air channel 13 enters the pressurization chamber through the air inlet 22, is pressurized, and then connected to the condensate storage chamber 24 through the pressurization pipe 23. The condensate is transported to the outlet of the cleaning pipe 21 and sprayed out under the action of the pressurized airflow to clean the fan impeller 3 of the range hood.

[0092] The range hood impeller 3 is cleaned using the condensate from the air conditioning module of the range hood. This effectively utilizes the condensate and cleans away grease, greatly improving the user experience of the range hood and enhancing the product's competitiveness.

[0093] In one alternative implementation, the air conditioning module is activated while the oil stain cleaning device 2 is activated.

[0094] The oil stain cleaning device 2 is started simultaneously with the air conditioning module. The condensate water generated when the air conditioner is working is discharged and utilized immediately. At the same time, the heat in the hot air duct 13 is also utilized to help the air conditioning module dissipate heat.

[0095] When the air conditioner range hood starts cooling, it will continuously produce condensate. The condensate is collected through the condensate pipe. The heat generated by the air conditioning module and the huge negative pressure generated by the range hood module drive the airflow. The condensate is then pressurized by the oil cleaning device 2 and then formed into a high-pressure water mist through the pressurized pipe 23 to clean the range hood impeller 3 inside the volute 4. Finally, the oil cup 5 collects the cleaned condensate for treatment.

[0096] This solution effectively treats the condensate water produced by the air conditioner range hood while cleaning the range hood impeller 3, effectively preventing excessive condensate water from affecting the electronic components of the range hood and preventing the extremely poor user experience caused by condensate water overflow.

[0097] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
