Range hood

Abstract

The utility model relates to a range hood which comprises a machine body, the oil cup is detachably mounted on the machine body; the oil cup further comprises a refrigerating device, the refrigerating device is provided with a refrigerating end, the refrigerating end extends into the oil cup, and a distance is formed between the refrigerating end and the bottom wall of the oil cup in the vertical direction. After the refrigeration device is started, the temperature of the middle-upper half layer of oil dirt in the oil cup is reduced, and the oil dirt is in a semi-solidified state, so that the flowability of the oil dirt is reduced, and the oil dirt is not easy to spill when a user moves the oil cup. Particularly, when the oil is poured out from the opening of the oil cup, due to the supporting effect of the solid layer, the oil is not prone to gushing out in a large amount at a time, and therefore the risk of spilling is reduced. And meanwhile, the solid layer can slow down the flow speed of the oil to a certain extent, so that the dumping process is more controllable.

Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a range hood. Background Art

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. An oil cup is often installed at the bottom of the range hood. For example, a close-suction range hood has a long strip of oil cup installed at the bottom rear side of the body to collect oil. When the oil reaches a certain amount, the oil cup is removed for cleaning. However, since the oil has a certain fluidity, it is difficult for the user to keep the oil cup in a horizontal state when removing it, which will cause the oil to flow out and drip onto the table, the ground, etc.

[0003] In order to solve the above technical problems, a Chinese invention patent application with application number CN202310073990.0 (application publication number: CN116123583A) discloses a range hood and a control method thereof, the range hood comprising a body, an exhaust assembly, an oil cup and a condensation assembly, the body having a smoke exhaust passage inside, and the body having a connecting hole connected to the smoke exhaust passage; the exhaust assembly is arranged in the body for sucking the smoke into the smoke exhaust passage; the oil cup is arranged on the body and is located outside the smoke exhaust passage for collecting oil; the condensation assembly is arranged on the body, the condensation assembly comprises a hot end and a cold end, the hot end is located in the smoke exhaust passage, the cold end passes through the connecting hole and extends outside the smoke exhaust passage, the cold end is used to absorb heat in the oil in the oil cup, and the heat on the cold end can be transferred to the hot end. The condensation component can absorb the heat of the oil cup. As the temperature of the oil decreases, the fluidity of the oil becomes worse. In this way, when the user needs to clean the oil in the oil cup and remove the oil cup, the oil can be prevented from spilling, thereby improving the user experience.

[0004] However, the above patent application still has certain shortcomings. The cold end of the condensation component in the above patent application basically cools down the entire oil cup, so that the entire oil in the oil cup may be completely solidified. If the oil as a whole is in a completely solidified state, it is not easy to pour out, and it is very inconvenient to clean.

[0005] Therefore, existing range hoods need further improvement. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a range hood which can avoid the problem of oil spilling when the oil cup is removed and can conveniently clean the oil in the oil cup in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the above technical problems is: a range hood, comprising:

[0008] Body;

[0009] An oil cup, detachably mounted on the machine body;

[0010] It also includes a refrigeration device, which has a refrigeration end. The refrigeration end extends into the oil cup and has a distance from the bottom wall of the oil cup in the up and down directions.

[0011] Considering that the oil cup is in the shape of a long strip, the oil is most likely to spill out at the left and right ends of the oil cup during removal. Therefore, the oil cup is in the shape of a long strip, and the refrigeration end is arranged at least at the end of the oil cup.

[0012] In order to improve the refrigeration efficiency, there are multiple refrigeration ends, which are arranged in sequence along the length direction of the oil cup.

[0013] Preferably, there are three refrigeration ends, which are respectively arranged on the left and right sides of the oil cup and in the middle of the left and right directions.

[0014] The cooling ends are arranged at three locations on the left and right sides and in the middle of the oil cup, which divides the oil cup into two parts and shortens the moving distance of the oil. Refrigeration modules are also arranged at the positions on both sides where the oil is most likely to spill. The cooling areas on both sides are also buffer zones for the movement of the oil in the middle. That is, when the oil in the middle moves to this place, it will first encounter the semi-solidified oil on both sides, causing a collision, thereby reducing the potential energy, and will not overflow directly from the edge of the oil cup.

[0015] Generally, the refrigeration device can be started by manual control of the user. In order to automatically start the refrigeration device when the oil reaches the set liquid level, it also includes a liquid level sensor for identifying the oil level in the oil cup. The liquid level sensor and the refrigeration device are electrically connected to the control system of the range hood. The control system can control the opening and closing of the refrigeration device according to the oil level signal transmitted by the liquid level sensor.

[0016] In order to facilitate users to check the working status of the refrigeration device, a status identification device for displaying the working status information of the refrigeration device is also included.

[0017] As an improvement, the state recognition device adopts at least one of an indicator light and a sound alarm.

[0018] As a further improvement, the machine body is further provided with an operation button for controlling the refrigeration device, and the state identification device is an indicator light arranged in the area where the operation button is located.

[0019] In order to install the refrigeration device, the machine body includes a machine body, the oil cup is installed at the bottom of the machine body, the main body of the refrigeration device is arranged in the machine body, and a through hole is opened on the bottom wall of the machine body for the refrigeration end of the refrigeration device to pass through.

[0020] As an improvement, the refrigeration device adopts a semiconductor refrigeration element. It is conceivable that the refrigeration device can also adopt other existing air-cooling or mixed-cooling devices.

[0021] Compared with the prior art, the utility model has the following advantages: since the refrigeration end of the refrigeration device extends into the oil cup and has a gap with the bottom wall of the oil cup in the vertical direction, after the refrigeration device is started, the temperature of the upper half of the oil stain in the oil cup is reduced and is in a semi-solidified state, thereby reducing the fluidity of the oil stain, and facilitating the user to move the oil cup so that the oil stain is not easy to spill. Especially when pouring out from the mouth of the oil cup, due to the supporting effect of the solid layer, the oil is not easy to gush out in large quantities at one time, thereby reducing the risk of spilling. At the same time, the solid layer can also slow down the flow rate of the oil to a certain extent, making the pouring process more controllable. On the other hand, the oil in the oil cup that is not completely solidified still maintains a certain fluidity, which makes it easier to pour out or wipe off the residual oil during the cleaning process. If the oil is completely solidified, additional heating or dissolving measures may be required to remove it, which undoubtedly increases the difficulty and cost of cleaning.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0027] Figure 1-Figure 3A preferred embodiment of the range hood of the utility model is shown. The range hood includes a body 10 and a centrifugal fan arranged in the body. The body 10 generally includes a fan frame 11 and a fume hood 12 arranged at the bottom of the fan frame 11. The inner cavity of the fan frame 11 is connected to the inner cavity of the fume hood 12. An air inlet is provided on the front side wall of the fume hood 12, and external smoke can enter the fume hood 12 through the air inlet. The centrifugal fan is arranged in the fan frame 11. When the centrifugal fan is running, negative pressure is generated, and external oil smoke can be sucked into the fume hood 12 through the air inlet. An oil net is also provided at the air inlet of the fume hood 12 for filtering oil smoke. An oil cup 13 is provided at the bottom of the fume hood 12. The oil cup 13 is in the shape of a long strip extending left and right, and is used to receive the oil stains flowing down from the fume hood 12. The oil cup 13 can be installed to the rear side of the bottom of the machine body by conventional snap-fit ​​and plug-in matching, so that the oil cup 13 can be removed and the oil in the oil cup 13 can be dumped. The front part of the smoke hood 12 is also provided with a smoke baffle 14 that can be deflected forward and backward relative to the smoke hood 12. The smoke baffle 14 is connected to the main body of the smoke hood 12 through a hinge motion mechanism. Specifically, it can be deflected forward to open the above-mentioned air inlet and deflected backward to block and close the above-mentioned air inlet. The hinge motion mechanism used to drive the deflection of the smoke baffle 14 can adopt a conventional hinge motion mechanism in the prior art, which will not be repeated here.

[0028] The range hood further includes a refrigeration device 20. The refrigeration device 20 of the present embodiment may be a semiconductor refrigeration component having a refrigeration end 21. Three semiconductor refrigeration components may be provided, respectively disposed on the left and right sides of the bottom of the smoke hood 12 and in the middle of the left and right directions. Specifically, the main bodies of the three semiconductor refrigeration components are disposed in the smoke hood 12, and a through hole 120 is provided on the bottom wall of the smoke hood 12 for the refrigeration end 21 of the semiconductor refrigeration component to pass through. The refrigeration ends 21 of the three semiconductor refrigeration components extend into the oil cup 13 after passing through the through hole 120, and are spaced apart from the bottom wall of the oil cup 13 in the up and down directions. Figure 3 As shown, the vertical distance L between the cooling end 21 and the bottom wall of the oil cup 13 can be about half of the overall height of the oil cup 13. The cooling ends 21 of the three semiconductor refrigeration components also correspond to the left and right sides of the oil cup 13 and the middle position in the left and right directions.

[0029] The refrigeration end 21 of the refrigeration device 20 is set at three locations on the left and right sides and the middle of the oil cup 13, which divides the oil cup 13 into two parts, the left and right parts, and shortens the moving distance of the oil. Refrigeration modules are also set at the positions on both sides where the oil is most likely to spill. The refrigeration areas on both sides are also buffer zones for the movement of the middle oil. That is, when the middle oil moves to this place, it will first encounter the semi-solidified oil on both sides, resulting in a collision, thereby reducing the potential energy, and will not directly overflow from the edge of the oil cup 13.

[0030] The range hood of this embodiment further includes a liquid level sensor (not shown) for identifying the oil level of the oil cup 13 and a state recognition device for displaying the working state information of the refrigeration device 20. The liquid level sensor and the refrigeration device 20 are both electrically connected to the control system of the range hood, and the control system can control the opening and closing of the refrigeration device 20 according to the oil level signal transmitted by the liquid level sensor. The state recognition device can be at least one of an indicator light and a sound alarm. Preferably, an operation button 15 for controlling the refrigeration device 20 is also provided on the machine body, and the above-mentioned state recognition device is set as an indicator light 16 arranged in the area where the operation button 15 is located.

[0031] When the depth of the oil stain in the oil cup 13 reaches a certain height, the liquid level sensor recognizes this, the refrigeration module automatically starts, and the "refrigeration" button on the operation button (that is, the indicator light 16) is on for a long time, prompting the user that the oil stain has reached the cleaning height and needs to be cleaned. At this time, the refrigeration device 20 has started refrigeration, and the refrigeration mode runs for a set time (for example, 30s or 1min, depending on the power of the refrigeration module). After the refrigeration is completed, the "refrigeration" button flashes, indicating that the refrigeration has ended. After the user removes the oil cup 13, press the operation button to return to normal.

[0032] Since the refrigeration end 21 of the refrigeration device 20 extends into the oil cup 13 and has a gap with the bottom wall of the oil cup 13 in the vertical direction, after the refrigeration device 20 is started, the temperature of the upper half of the oil stain in the oil cup 13 is reduced and is in a semi-solidified state, thereby reducing the fluidity of the oil stain, which is convenient for the user to move the oil cup 13 and prevent the oil stain from spilling. Especially when pouring out from the mouth of the oil cup 13, due to the supporting effect of the solid layer, the oil is not easy to gush out in large quantities at one time, thereby reducing the risk of spilling. At the same time, the solid layer can also slow down the flow rate of the oil to a certain extent, making the pouring process more controllable. On the other hand, the oil that is not completely solidified in the oil cup 13 still maintains a certain fluidity, which makes it easier to pour out or wipe off the residual oil during the cleaning process. If the oil is completely solidified, additional heating or dissolving measures may be required to remove it, which undoubtedly increases the difficulty and cost of cleaning.

[0033] On the basis of the above embodiments, other embodiments can be obtained by replacing and improving the relevant technical features. For example, in addition to using semiconductor refrigeration components, the refrigeration device 20 can also use other existing air-cooling or mixed-cooling devices, with a heat-conducting plate or heat-conducting column that exchanges heat with the refrigeration element of the air-cooling or mixed-cooling device as the refrigeration end 21 extending into the oil cup 13.
