Description

Technical Field

[0001] The utility model belongs to the technical field of frying machines and relates to a frying machine which is easy for food residues to settle. Background Art

[0002] A deep fryer is a device used for high-temperature deep frying of food, which can fry food in batches and accelerate the food cooking process. In order to facilitate the discharge of food residues generated during the frying process, existing deep fryers often add an oil-water separation design to the deep fryer, that is, oil and water are added to the deep fryer so that the oil with a lower density floats on the upper end of the water, and the water in the oil-water is located at the lower layer and keeps a low temperature. The food residues generated during the frying process will settle in the water at the bottom, so that the residues can be discharged with the water without filtering treatment, and at the same time, the adverse effects of food residues on the food are avoided.

[0003] For example, CN202020406923.8 discloses a food fryer, comprising a box body, a workbench connected to the upper end of the box body, a frying pool provided in the workbench, a lifting rod movable up and down is installed on the workbench, a frying basket that can enter the frying pool is connected to the lifting rod, and a driving mechanism that can control the lifting rod to move up and down is also connected to the lifting rod, and the frying pool comprises an oil storage area at the upper end and a water storage area at the lower end.

[0004] The above-mentioned frying machine realizes oil-water separation by setting up an oil storage area and a water storage area in the frying pool. However, in order to ensure uniform frying, the frying machine often needs to turn the food in it, but when turning the food in the frying machine with oil and water added, it is very easy to cause the oil and water in the frying machine to mix. Since the boiling points of oil and water are different, and the boiling point of water is much lower than that of oil, water will boil and vaporize when it contacts the high-temperature oil, and the volume of water will expand rapidly, causing oil and water splashing, which is very easy to scald the user of the frying machine.

[0005] If only oil is used, food residues will not settle easily. The food residues will be in a process of being fried at high temperature all the time, which will easily produce a large amount of harmful substances for a long time and affect human health. In addition, the oil will be contaminated more quickly, making oil replacement more frequent.

[0006] In view of the above problems, a frying machine can be designed which can facilitate the sedimentation of food residues, prevent the food residues from being fried repeatedly, and prevent the oil from splashing. Summary of the invention

[0007] In view of the above problems, the utility model provides a frying machine which is easy for food residues to settle. The frying machine can not only facilitate the sedimentation of food residues in the frying machine, but also prevent oil splashing when food is turned over.

[0008] The purpose of the utility model is achieved in this way:

[0009] A frying machine that is easy for food residues to settle, comprising a machine body, a frying pool for placing oil in the machine body, a heating pipe and a cooling pipe arranged in the frying pool, the cooling pipe being arranged below the heating pipe and spaced a certain distance apart, the heating pipe and the cooling pipe dividing the frying pool into three areas from top to bottom, namely a frying area above the heating pipe, a transition area between the heating pipe and the cooling pipe, and a settling area below the cooling pipe, and a cooling circulation device for controlling the operation of the cooling pipe is arranged in the machine body.

[0010] Furthermore, the cooling circulation device includes a switching power supply, a liquid reservoir, a radiator and a circulation pump. A liquid outlet pipe is connected between the liquid reservoir and the cooling pipe, a liquid inlet pipe is connected between the radiator and the cooling pipe, and the liquid reservoir, radiator and circulation pump are connected through a liquid guide pipe.

[0011] Furthermore, the radiator includes a cold row and a cooling fan blowing air toward the cold row.

[0012] Furthermore, the switching power supply is connected to a power supply fan.

[0013] Furthermore, a temperature detector is provided in the body, and the detection end of the temperature detector is connected to the bottom of the frying pool for measuring the temperature of the bottom of the frying pool. The control end of the temperature detector is connected to the circulation pump. When the temperature reaches the start setting value, the circulation pump is controlled to start working. When the temperature drops to the provisional setting value, the circulation pump is controlled to stop working.

[0014] Furthermore, the start setting value is 50°C, and the pause setting value is 40°C.

[0015] Furthermore, a control panel is formed on the machine body.

[0016] Furthermore, a drain valve communicating with the sedimentation area is formed at the lower end of the frying pool.

[0017] Furthermore, a filter screen is provided in the frying area, and the filter screen is arranged above the heating tube and is arranged at intervals.

[0018] Furthermore, a coolant flows in the cooling pipe.

[0019] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:

[0020] 1. Only oil is added to the fryer, so even if the food is turned over during frying, the oil in the frying pool will not splash out.

[0021] 2. Due to the functions of the heating tube and the cooling tube, the frying pool is divided into a frying zone, a transition zone and a sedimentation zone. The oil temperature in the sedimentation zone is lower than that in the frying zone, and the density of the oil increases as the temperature decreases, so that the oil in the sedimentation zone is in a stable low-temperature state. Therefore, food residues dropped during the frying process will always sink in the oil in the sedimentation zone 12, and even if it is stirred in the middle, it can be quickly precipitated again.

[0022] 3. Since the food residue sinks into the sedimentation area, that is, sinks to the bottom of the frying pool, the convenient discharge of the food residue is effectively realized, and the food residue can be discharged simultaneously with the oil at the bottom.

[0023] 4. The cooling circulation device in the fryer allows the coolant in the cooling tube to be recycled and maintained at a suitable temperature, thereby cooling the oil in the sedimentation area and making the temperature in the sedimentation area much lower than that in the frying area, so that the food residues sink to the bottom. Due to the low temperature in the sedimentation area, the oil will not boil and the food residues will not roll over, and they can sink to the bottom for a long time.

[0024] 5. Since food residues sink to the bottom for a long time, the oil is cleaner, and the oil is only locally hot, and there will be no large-scale oxidation and blackening, which extends the service life of the oil, improves the utilization rate of the oil, and plays a role in saving resources.

[0025] 6. The temperature of the oil in the sedimentation area of ​​the frying pool can be detected by the temperature detector, so as to control the working state of the cooling circulation device, so that the cooling circulation device can adjust the working state according to the temperature of the oil, thereby saving the energy consumption of the cooling circulation device.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0034] The present invention will be further described below with reference to specific embodiments of the invention.

[0035] like Figure 1-3 As shown, a splash-proof fryer includes a body 0, a frying pool 1 for putting oil is installed on the body 0, a heating pipe 5 and a cooling pipe 2 are arranged in the frying pool 1, the cooling pipe 2 is arranged below the heating pipe 5 and is spaced a certain distance apart, the heating pipe 5 and the cooling pipe 2 divide the frying pool into three areas from top to bottom, namely a frying area 11 above the heating pipe, a transition area 14 between the heating pipe 5 and the cooling pipe 2, and a sedimentation area 12 below the cooling pipe, and a cooling circulation device 4 for controlling the operation of the cooling pipe 2 is arranged in the body 0. Specifically, in the fryer, only oil is added to the frying pool 1, and the heating pipe 5 and the cooling pipe 2 are both operated, so that the oil temperatures of the frying area 11, the transition area 14, and the sedimentation area 12 are in different states. The temperature of the frying area 11 above the heating tube 5 is maintained at the temperature required for frying, and the transition area 14 between the heating tube 5 and the cooling tube 2 shows a gradual decrease in oil temperature from top to bottom. The temperature of the precipitation area below the cooling tube 2 is the lowest. The density of the oil increases as the oil temperature decreases, so the oil in the precipitation area is in a stable low-temperature state. Therefore, the food residues dropped during the frying process will always sink in the oil in the precipitation area 12. Compared with repeatedly frying food residues in the frying area (which will produce more harmful substances and make the oil turbid faster), this can better keep the oil clean and extend the use time of the oil. And because the fryer uses only oil, even if the food is turned over during the frying process, there is no water in the oil in the frying pool, so there will be no oil splashing and scalding.

[0036] When cleaning, the user only needs to open the drain valve 13 to drain the oil in the sedimentation area 12, and then drain the food residue therein.

[0037] like Figure 4-5 As shown, the cooling circulation device 4 includes a switching power supply 41, a liquid reservoir 42, a radiator 43 and a circulation pump 44. A liquid outlet pipe 45 is connected between the liquid reservoir 42 and the cooling pipe 2, a liquid inlet pipe 46 is connected between the radiator 43 and the cooling pipe 2, and the liquid reservoir 42, the radiator 43 and the circulation pump 44 are connected by a liquid guide pipe 47. Specifically, in the cooling circulation device 4, the circulating pump 44 can realize the control of the circulation of the coolant. When the coolant passes through the cooling pipe 2 to cool the oil in the sedimentation zone 12 and the transition zone 14, the coolant will cause its own temperature to rise by absorbing the heat in the oil. The circulating pump 44 can extract the coolant in the cooling pipe 2, and the coolant can enter the reservoir 42 after passing through the liquid outlet pipe 45. The reservoir 42 can store the coolant. The circulating pump 44 can also make the coolant in the reservoir 42 flow out through the liquid guide pipe 47, and then the coolant is sent to the radiator 43 for cooling. The cooled coolant leaves the radiator 43 and is sent to the liquid inlet pipe 46 by the circulating pump 44. The coolant is washed back into the cooling pipe 2 after passing through the liquid inlet pipe 46, so that the cooling pipe 2 can continue to cool the oil in the sedimentation zone 12 and the transition zone 14. The cooling circulation device 4 realizes the recycling of the coolant and effectively reduces the temperature of the oil in the sedimentation zone 12 and the transition zone 14 .

[0038] As an improved embodiment, the radiator 43 includes a cold row 431 and a cooling fan 432 blowing air toward the cold row 431. Specifically, the coolant carries heat through the liquid guide pipe to the cold row 431. The cold row 431 is a flat metal heat sink. There are micro-water channels inside the metal heat sink. Multiple lines carry water through a large number of Z-shaped heat sink fins in the middle (existing technology). The water reduces its temperature when flowing through the heat sink, and the cooling fan 432 accelerates the cooling of the coolant.

[0039] As an improved embodiment, a power supply fan 411 is connected to the switching power supply 41. Specifically, the power supply fan 411 blows cold air toward the switching power supply 41, which can achieve a certain cooling effect when the switching power supply 41 is working.

[0040] As an improved embodiment, a temperature detector 6 is provided in the body 0, and the detection end of the temperature detector 6 is connected to the bottom of the frying pool 1 to measure the temperature of the bottom of the frying pool 1. The control end of the temperature detector 6 is connected to the circulation pump 44. When the temperature reaches the set value, the circulation pump 44 is controlled to work. Specifically, the temperature detector can be connected to the bottom of the frying pool 1, and sense the temperature of the bottom of the frying pool 1 through elements such as thermal resistors and thermocouples. Since the sedimentation area 12 is located at the lower end of the frying pool 1, the temperature of the oil in the sedimentation area 12 can be obtained by sensing the bottom of the frying pool 1. When the temperature detector 6 detects that the temperature of the oil in the sedimentation area 12 is higher than the start setting value, the temperature detector 6 controls the circulation pump 44 to work, so that the coolant in the cooling circulation device starts to circulate. When the temperature detected by the temperature detector 6 is lower than the pause setting value, the temperature detector 6 controls the circulation pump 44 to stop working, so as to prevent the cooling circulation device 4 from being in a working state for a long time, and play a role in protecting the device and saving energy.

[0041] As an improved embodiment, the start setting value is 50° C. Specifically, when the temperature detector 6 detects that the temperature of the oil at the bottom of the frying pool 1, that is, in the sedimentation area 12, reaches 50° C., the temperature detector 6 can control the circulation pump 44 to start working. The start setting value can be set according to the specific needs of the user.

[0042] The start setting value is 40°C. When the temperature detector 6 detects that the bottom of the frying pool 1, that is, the oil temperature in the sedimentation area 12 reaches 40°C, the temperature detector 6 can control the circulation pump 44 to stop working. The pause setting value can be set according to the specific needs of the user. The start setting value and the pause setting value are preferably kept at a difference of about 10 degrees.

[0043] like Figure 1 As shown, a control panel 7 is formed on the body 0. Specifically, the user can adjust the temperature, working time and other values ​​of the frying machine through the control panel 7.

[0044] like Figure 2 As shown, a drain valve 13 communicating with the sedimentation area 12 is formed at the lower end of the frying pool 1. Specifically, the oil with food residues deposited in the sedimentation area 12 can be discharged through the drain valve 13.

[0045] like Figure 1-2As shown, a filter screen 3 is provided in the frying area 11, and the filter screen 3 is arranged above the heating tube 5 and is arranged at intervals. Specifically, the filter screen 3 can be used to filter impurities and residues generated when the food is fried in the frying pool 1, allowing fine residues to fall into the sedimentation area 12, and preventing intact food from falling into the sedimentation area 12, and can also prevent the food from directly contacting the heating tube during the frying process.

[0046] As an improved embodiment, a coolant flows in the cooling pipe 2. Specifically, the cooling pipe 2 cools the oil in the precipitation area 12 through the coolant inside the cooling pipe 2. The coolant can be water, alcohol, ethylene glycol, etc., as long as the corresponding effect is achieved.

[0047] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
