Description

Technical Field

[0001] This application relates to the technical field of food cooking equipment, and in particular to a deep fryer. Background Technology

[0002] Deep fryers are commonly used equipment in the culinary field. Their main function is to fry food in high-temperature oil to achieve a crispy texture. This equipment generally consists of a heating module, an oil tank, and a control system. It features the ability to quickly heat the frying oil and maintain a constant temperature, making it widely applicable for frying various foods such as French fries, chicken nuggets, and fish fillets.

[0003] In practical use, to achieve the reuse of frying oil and facilitate daily filtering of food residue from the oil in the frying tank, deep fryers with automatic oil filtering functions have appeared on the market. These deep fryers have an automatic oil filtering device installed at the bottom of the oil tank. This device mainly includes an oil drain valve connected to the bottom of the oil tank, an oil pump assembly for pumping the filtered oil back into the oil tank, and a filter barrel. During operation, the oil drain valve directs the frying oil from the oil tank to the filter barrel, where the filter barrel uses a filter screen to filter out food residue from the frying oil. Then, the oil pump pumps the filtered frying oil back into the oil tank, thus achieving automatic filtration and recycling of the frying oil.

[0004] However, frying inevitably produces fumes. To meet environmental regulations, users of fryers with automatic oil filtration functions must install additional fume extraction and purification equipment above the fryer to handle the fumes generated during frying. This not only significantly increases the cost of equipment purchase but also imposes many restrictions on the fryer's location due to the space requirements and installation conditions of the additional equipment, causing inconvenience to users. Utility Model Content

[0005] In order to simultaneously achieve automatic oil filtration and automatic fume extraction and purification functions, this application provides a deep fryer.

[0006] This application provides a deep fryer, which adopts the following technical solution:

[0007] A deep fryer includes an upper cabinet, a lower cabinet, an oil tank and an oil pump located in the upper cabinet, and a purification flue and a filter barrel located in the lower cabinet. The purification flue includes a purification box with a purification module inside and a fan box with a fan inside. A fume hood is provided on the rear side of the platform where the oil tank is fixed in the upper cabinet. The fume hood is connected to the purification box through a rear flue. An exhaust flue is provided on one side of the fume hood, which is connected to the fan box.

[0008] The bottom of the oil tank is connected to an oil drain pipe, which is equipped with an oil drain valve. The outlet of the oil drain pipe is located above the filter barrel. The oil pump is connected to the filter barrel through an oil pump inlet pipe and to the oil tank through an oil pump outlet pipe.

[0009] By adopting the above technical solution, the oil fumes overflowing from the oil tank are sucked into the fume hood, enter the purification box through the rear flue, and are then purified by the purification module before being sent out through the fan box, thus realizing the automatic oil fume suction and purification function. When oil filtration is required, the oil drain valve is opened to send the oil in the oil tank into the filter barrel. After filtration in the filter barrel, the oil is extracted by the oil pump and sent back to the oil tank.

[0010] In one embodiment: the filter barrel and the fan box are located on the same side of the lower cabinet, with the filter barrel in front and the fan box behind.

[0011] By adopting the above technical solution, the structural design is more reasonable, resulting in a compact overall structure.

[0012] In one embodiment: the filter barrel is a movable oil tank with wheels at the bottom and an opening at the top. The bottom of the filter barrel is provided with an oil extraction pipe, and the oil outlet of the oil extraction pipe is connected to the oil pump inlet pipe in a horizontal direction.

[0013] By adopting the above technical solution, the filter barrel is easy to move with wheels, and the upper opening makes it easy to connect the filter barrel directly to the oil drain pipe after installation. At the same time, the connection between the oil suction pipe and the oil pump inlet pipe can be completed immediately after installation.

[0014] In one embodiment: the upper cabinet side panel on the outer side of the filter barrel extends downward to form a positioning guide plate, the front panel of the filter barrel is provided with a positioning pin, and the side wall of the purification box is provided with a positioning hole that cooperates with the positioning pin.

[0015] By adopting the above technical solution, the positioning guide plate positions the filter barrel between the purification box and the positioning guide plate to prevent it from moving left and right, and the positioning pin fixes the filter barrel to prevent it from moving back and forth.

[0016] In one embodiment: the filter barrel is provided with a coarse filter screen, a fine filter screen, a filter paper pressure plate and a filter paper support from top to bottom, and the oil suction port at the lower end of the oil suction pipe is located below the filter paper support.

[0017] By adopting the above technical solution, the oil entering the filter tank from the opening undergoes multiple filtrations from top to bottom, with the filtration process progressing from coarse to fine, and finally being sucked into the oil suction pipe from the oil suction port.

[0018] In one embodiment: the upper cabinet is provided with an oil pump box located above the filter barrel in front of the exhaust flue, the oil pump and the oil drain valve are located in the oil pump box, and the upper cabinet door is provided in front of the oil pump box.

[0019] By adopting the above technical solution, the design of the upper cabinet door facilitates the opening and closing of the oil valve.

[0020] In one embodiment: the purification box is located at the front end of the lower cabinet, and the purification module includes an oil fume microparticle filter and an odor removal filter in sequence along the airflow direction. The oil fume microparticle filter is a high-voltage purification electric field and / or a HEPA filter, and the odor removal filter is one or more of an activated carbon filter, an ultraviolet lamp, and a photocatalyst filter.

[0021] In one embodiment: the air inlet side of the purification box is provided with a positioning guide strip for limiting the purification module. The positioning guide strip enables the air inlet end of the purification module and the air inlet side wall of the purification box to form an air inlet channel that communicates with the rear flue through a gap. The air inlet channel is provided with a flow equalization plate.

[0022] By adopting the above technical solution, an air intake channel is formed between the air intake sidewall of the purification chamber and the air intake sidewall, achieving a connection with the rear flue through the simplest structure. However, since the air intake direction of the air intake channel is perpendicular to the purification module, and the spacing cannot be too large, it is easy to cause uneven air intake to the purification module. The air distribution plate can make the air intake more uniform.

[0023] In one embodiment: the air outlet side of the purification box near the filter barrel is provided with a positioning guide for limiting the purification module. The positioning guide is used to form an air outlet channel between the air outlet side wall of the purification box and the purification module. The rear part of the air outlet side wall is provided with an air outlet that communicates with the fan box.

[0024] By adopting the above technical solution, the air outlet channel formed by the interval is used to achieve communication with the fan box.

[0025] In one embodiment, the hood has an grease filter at its air intake.

[0026] By adopting the above technical solution, grease suspensions and soot in oily fumes are filtered through the grease filter. Attached Figure Description

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] A deep fryer, such as Figure 1 and Figure 2 As shown, it includes an upper cabinet 100, a lower cabinet 200, an oil tank 300, a heater 310 and an oil pump 400 located in the upper cabinet 100, and a purification flue and filter barrel 600 located in the lower cabinet 200. The oil tank 300 is fixed on the table surface of the upper cabinet 100, and the heater 310 is located inside the oil tank 300 or on the bottom surface of the oil tank 300 to heat the frying oil in the oil tank 300.

[0038] Reference Figure 3 The upper cabinet 100 is located behind the oil tank 300 and has a rear flue 140, which connects to the fume hood 120 and the purification flue.

[0039] like Figure 1 and Figure 2 The upper cabinet 100 has an oil pump box 410 located above the filter barrel 600 in front of the exhaust duct 150. The upper cabinet door 110 is located in front of the oil pump box 410. The oil pump box 410 houses an oil pump 400 and an oil drain valve 420. An oil drain hole is located at the bottom of the oil tank 300, connected to an oil drain pipe 430. The oil drain valve 420 is installed on the oil drain pipe 430. The other end of the oil drain pipe 430 extends downwards through the bottom of the oil pump box 410 and down to the top of the filter barrel 600. Simultaneously, the horizontal position of the outlet of the oil drain pipe 430 above the filter barrel 600 is lower than the horizontal position of the oil drain hole. This design ensures that the scalded oil in the oil tank 300 can flow out sufficiently.

[0040] One of the surrounding plates of the oil tank 300 is provided with an oil return hole, which is located above the highest working oil level. The oil pump 400 is connected to the filter barrel 600 through the oil pump inlet pipe 440 and to the oil return hole of the oil tank 300 through the oil pump outlet pipe 450. The oil pump 400 pumps the filtered frying oil back into the oil tank 300.

[0041] See attached document Figure 2 and Figure 3 The upper cabinet 100 has a fume hood 120 on the back side of the fixed oil tank 300. The fume hood 120 has a grease filter screen 130 on the air intake. The grease filter screen 130 filters the oil grease suspension and soot in the oil fume gas.

[0042] The purification flue includes a purification box 210 with a purification module 700 inside and a fan box 220 with a fan 500 inside. The purification box 210 is located at the front end of the lower cabinet 200, and the fan box 220 is located at the rear end of the lower cabinet 200 and on one side of the purification box 210.

[0043] Combined with appendix Figure 4 An air intake channel 230 is formed between the air intake end of the purification module 700 and the air intake side wall 251 of the purification box 210, which is connected to the rear flue 140. The air intake channel 230 is formed between the purification module 700 and the side wall of the lower cabinet 200, and the connection with the rear flue 140 is achieved through the simplest structure.

[0044] Since the air intake direction of the air intake channel 230 is perpendicular to the purification module 700, the spacing cannot be made very large in order to achieve structural compactness, which can easily lead to uneven air intake of the purification module 700. Therefore, a flow equalization plate 240 is provided on the air intake channel 230. The flow equalization plate 240 can make the air intake more uniform.

[0045] The flow equalization plate 240 has an L-shaped cross-section and is vertically arranged. The flow equalization plate 240 divides the intake channel 230 into two channels, from which the air is delivered to the purification module 700.

[0046] The purification module 700 includes, in sequence along the airflow direction, an oil fume particulate filter 710 and an odor removal filter 720. The oil fume particulate filter 710 is a high-voltage purification electric field and / or a HEPA filter, and the odor removal filter 720 is one or more of an activated carbon filter, an ultraviolet lamp, and a photocatalyst filter. In this embodiment, two sets of oil fume particulate filters 710 are provided to improve the filtration effect.

[0047] The side wall of the purification box 210 near the filter barrel 600 is the air outlet side wall 252. The air outlet side wall 252 and the deodorizing mesh 720 are spaced apart to form an air outlet channel 260. The rear part of the air outlet side wall 252 is provided with an air outlet 270 that communicates with the fan box 220.

[0048] Among them, refer to the appendix Figure 5 Two positioning guides 280 are installed at the bottom of the lower cabinet 200. The two positioning guides 280 are respectively located on the air inlet side and the air outlet side of the purification module 700. The positioning guides 280 position the purification module 700 to maintain a distance from the air inlet side wall 251 and the air outlet side wall 252 of the purification box 210. This ensures that there is sufficient space for purified gas to flow between the purification module 700 and the air inlet side wall 251 and the air outlet side wall 252, thereby effectively ensuring that the oil fume gas passes through the entire filter surface of the purification module 700 and improving the purification efficiency of the purification module 700.

[0049] Additionally, please refer to the appendix. Figure 1 and attached Figure 5 The purification box 210 is equipped with a purification box door 290 at the front, which is designed to facilitate the opening of the door to maintain and replace the purification module 700.

[0050] like Figure 1 and Figure 3 As shown, the smoke hood 120 has an exhaust flue 150 connected to the fan box 220 on one side, and the top of the upper cabinet 100 has a smoke outlet 160 of the exhaust flue 150.

[0051] A deep fryer switch panel bracket 170 is fixed on the front panel of the exhaust duct 150, and a control switch is provided on the front surface of the deep fryer switch panel bracket 170.

[0052] like Figure 6 As shown, the filter cartridge 600 and the fan box 220 are located on the same side of the lower cabinet 200, with the filter cartridge 600 in front and the fan box 220 behind.

[0053] The filter canister 600 is a movable oil tank with wheels at the bottom and an open top, which facilitates the removal of the filter canister 600 from the lower cabinet 200 for placing filter paper and cleaning and maintenance. The bottom of the filter canister 600 is equipped with an oil suction pipe 610, and the oil outlet of the oil suction pipe 610 is horizontally connected to the oil pump inlet pipe 440.

[0054] Specifically, the oil pump inlet pipe 440 is provided with a horizontal outward interface that is horizontally connected to the oil outlet end of the oil suction pipe 610 of the filter tank 600. The interface of the oil pump inlet pipe 440 is designed to be slightly larger in diameter than the oil outlet end of the oil suction pipe 610. The oil outlet end of the oil suction pipe 610 is inserted into the interface of the oil pump inlet pipe 440, and the two are tightly connected by a sealing ring.

[0055] See attached document Figure 6 and attached Figure 7 The rear panel 670 of the filter canister 600 is lower than the outlet of the drain pipe 430, while the front panel of the filter canister 600 is higher than the outlet of the drain pipe 430 and is tightly connected to the upper cabinet 100. This design facilitates the removal of the filter canister 600 from the front of the lower cabinet 200 without interfering with the drain pipe 430. Furthermore, it ensures that the outlet of the filter canister 600 and the outlet of the drain pipe 430 are not exposed when the filter canister 600 is not removed from the lower cabinet 200, preventing foreign objects from entering the filter canister 600 and the drain pipe 430.

[0056] See attached document Figure 1 and Figure 7 A positioning guide plate 180 extends downward from the side panel of the upper cabinet 100 on the outer side of the filter cartridge 600. The positioning guide plate 180 positions the filter cartridge 600 between the exhaust side wall 252 of the purification chamber 210 and the positioning guide plate 180. A positioning pin 620 is provided on the front panel of the filter cartridge 600, and a positioning hole that mates with the positioning pin 620 is provided on the side wall of the purification chamber 210. The positioning pin 620 adopts an elastic structure, which allows it to be held inserted into the positioning hole by elastic force when no external force is applied. After the positioning pin 620 is locked, it prevents it from moving left or right, and it fixes the filter cartridge 600 to prevent it from moving back and forth.

[0057] See attached document Figure 6 The filter barrel 600 is provided with a coarse filter screen 630, a fine filter screen 640, a filter paper pressure plate 650 and a filter paper support 660 from top to bottom. Both the coarse filter screen 630 and the fine filter screen 640 are installed in the filter barrel 600 with a detachable structure.

[0058] The filter paper support 660 has a mesh structure, and the filter paper pressure plate 650 is pressed onto the filter paper support 660 by gravity. The filter paper can be pressed onto the filter paper support 660 by the filter paper pressure plate 650, and when the filter paper needs to be replaced, the filter paper pressure plate 650 can be lifted directly, making replacement convenient. The oil suction port at the lower end of the oil suction pipe 610 is located below the filter paper support 660. In this way, the oil entering the filter tank 600 from the opening undergoes multiple filtrations from top to bottom, with the filtration process progressing from coarse to fine, and finally is sucked into the oil suction pipe 610 through the oil suction port.

[0059] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
