Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a purification module for a range hood, a range hood, and a range hood and stove integrated machine. Background Art

[0002] A gas stove is a kitchen appliance used to provide direct fire heating for cooking, and a range hood is a kitchen appliance used to quickly extract the exhaust gas generated by the gas stove and the oil smoke generated during the cooking process and discharge them to the outside to purify the cooking air. As the name suggests, a range hood is a kitchen appliance that integrates a gas stove and a range hood into one and has the functions of direct fire heating and cooking and purifying the cooking environment. A range hood usually includes a stove, a gas stove and a range hood. The gas stove is installed on the countertop of the stove, and the range hood is installed at the end of the stove away from the user. The range hood has a smoke hood, a fan arranged in the smoke hood, and an air duct connected to the exhaust system. The fan is used to allow the oil smoke to enter the smoke hood from the air inlet of the smoke hood and flow from the air duct to the exhaust system.

[0003] When users perform cooking activities such as stir-frying and grilling, a large amount of oil smoke will be generated. After the range hood sucks the oil smoke into the smoke hood, some of the oil stains in the oil smoke will separate from the smoke and accumulate in the smoke hood. The oil stains accumulated in the smoke hood are not only not conducive to subsequent cleaning, but also accumulate on the impeller of the fan for a long time, which can easily affect the normal operation of the fan.

[0044] Figure 1 The schematic diagram of the structure of the smoke and stove integrated machine provided by the present application is shown. Figure 1As shown, the range hood integrated machine includes a stove 300, a gas stove 200, a range hood 100 and a main control system. The gas stove 200 is installed on the table of the stove 300, and the range hood 100 is erected at the end of the stove 300 away from the user. The main control system can be used to control the opening and closing of the range hood 100 and the working mode of the range hood 100 according to user instructions or control the opening and closing of the range hood 100 and the working mode of the range hood 100 according to monitoring data. The gas stove 200 is used to provide direct fire to facilitate user cooking, and the range hood 100 is used to absorb the exhaust gas generated by the gas stove 200 and the fumes generated during cooking and discharge them to other places outside the cooking environment, so as to purify the cooking environment and improve the user's cooking experience.

[0045] It should be noted that in the present application, the specific structure inside the range hood 100, the wind curtain design of the range hood and stove integrated machine, and the control method of the range hood 100 are the main invention points of the present application, while the structure of the gas stove 200 and the assembly method of the gas stove 200 and the stove top 300 can adopt mature technical solutions in the prior art, which will not be repeated here.

[0046] Next, for the sake of ease of understanding, the upper end of the overall smoke and stove integrated machine in the vertical direction is defined as the "upper end" or "above", and the lower end of the overall smoke and stove integrated machine in the vertical direction is defined as the "lower end" or "below"; the end of the overall smoke and stove integrated machine closer to the user is defined as the "front end", and the end of the overall smoke and stove integrated machine away from the user is defined as the "rear end"; the left side of the user when the user is facing the smoke and stove integrated machine is defined as the "left side", and the right side of the user when the user is facing the smoke and stove integrated machine is defined as the "right side".

[0047] Figure 2 Shows Figure 1 A cross-sectional view of a central smoke and stove combination machine. Figure 2 Combination Figure 1 As shown, the smoke hood 100 includes a smoke hood 1, a main fan 2 and a smoke exhaust system (not shown in the figure), the smoke hood 1 includes a front wall plate 11, a rear wall plate 12, a left wall plate, a right wall plate 13 and an upper wall plate, the front wall plate 11 and the rear wall plate 12 are arranged at intervals in the front-to-back direction, the left wall plate and the right wall plate 13 respectively cover the interval between the front wall plate 11 and the rear wall plate 12 in the left-to-right direction, and the upper wall plate covers the interval between the front wall plate 11 and the rear wall plate 12 at the top. The smoke hood 1 has an air guide channel 10, the main fan 2 is installed in the air guide channel 10, the front wall plate 11 of the smoke hood 1 has an air inlet 101 connected to the air guide channel 10, and the lower end of the smoke hood 1 has an exhaust air outlet 102 connected to the air guide channel 10. When the main fan 2 is started, negative pressure will be generated in the air guide channel 10, which will draw the oil smoke into the air guide channel 10 from the air inlet 101, and then make the oil smoke enter the exhaust channel of the exhaust system through the exhaust outlet 102, and finally be discharged to other places under the action of the exhaust system.

[0048] exist Figure 2 In the example, the number of main fans 2 is two, and the two main fans 2 are arranged at intervals along the oil fume flow direction in the air guide channel 10, and the front wall surfaces of the two main fans 2 are in contact with the inner surface of the front wall plate 11 of the smoke hood 1, and the rear wall surfaces of the two main fans 2 are in contact with the inner surface of the rear wall plate 12 of the smoke hood 1. In other embodiments, the number of main fans 2 is not limited to one or two, and can also be three, four, five, etc., and can be specifically designed according to the relationship between the overall size of the range hood 100 and the size of the main fans 2 and the required oil fume suction power, which is not limited here. It can be understood that the more the number of main fans 2, the higher the oil fume suction efficiency of the range hood 100, but the higher the cost of the range hood 100.

[0049] In order to allow more oil smoke to enter the air guide channel 10 in the smoke hood 1 from the air inlet 101 of the smoke hood 1, the upper end of the front wall plate 11 has an arc-shaped air inlet portion that gradually extends forward from bottom to top, and the air inlet 101 is opened in the arc-shaped air inlet portion. When the user is cooking, the main fan 2 is started, and the oil smoke floats upward. When the oil smoke floats to the arc-shaped air inlet portion, it will stagnate and accumulate at the arc-shaped air inlet portion under the blocking effect of the arc-shaped air inlet portion. Since the main fan 2 generates negative pressure in the air guide channel 10, the oil smoke at the arc-shaped air inlet portion quickly enters the air guide channel 10 under the suction effect of the negative pressure, thereby improving the oil smoke suction efficiency of the range hood 100.

[0050] In one embodiment, the air inlet 101 is a long hole extending along the arc surface of the arc-shaped air inlet portion, and a plurality of long holes are arranged at intervals along the left and right directions of the arc-shaped air inlet portion to form a group of air inlet 101. Such an arrangement can not only improve the efficiency of the range hood 100 in absorbing oil fumes, but also prevent larger debris from being sucked into the air guide channel 10, thereby ensuring the normal operation of the air guide channel 10.

[0051] The hood 100 further includes a purification module 5, which is installed in the air guide channel 10 and located upstream of the main fan 2. The purification module 5 is used to purify the oil smoke. This arrangement can reduce the amount of oil pollution in the air guide channel 10, which can not only reduce the impact of oil pollution on the main fan 2 and ensure that the main fan 2 can work stably, but also facilitate the cleaning of the smoke hood 1. In addition, the oil pollution in the oil smoke is removed by the purification module 5. When the oil smoke is discharged to the public exhaust pipeline through the exhaust system, it can also avoid blocking the pipeline of the exhaust system due to excessive oil pollution.

[0052] In one embodiment, the stove 300 has an air curtain channel 301, and the tabletop of the stove 300 has an air curtain outlet 302 arranged along the circumference of the stove 300 and connected to the air curtain channel 301; the lower end of the smoke collecting hood 1 has an inner air outlet 103 connecting the air guide channel 10 and the above-mentioned air curtain channel 301, that is, the oil smoke in the air guide channel 10 can enter the air curtain channel 301 and form an air curtain from the air curtain outlet 302 to reduce the diffusion of oil smoke and improve the efficiency of oil smoke absorption. In addition, through the air curtain design, it is also possible to improve the efficiency of oil smoke absorption without increasing the fan noise, improve the user's cooking comfort, and improve the competitiveness of the product. In actual application, when the user is cooking, the oil smoke floats upward to the air inlet 101 of the smoke hood 1. Under the action of the main fan 2, the oil smoke enters the air guide channel 10 from the air inlet 101 and is purified by the purification module 5. It can then enter the wind curtain channel 301 from the exhaust air outlet 103 and finally be blown out from the wind curtain outlet 302 to form a wind curtain. Using the purified oil smoke to form a wind curtain can not only prevent the cooking oil smoke from spreading, but also allow more oil smoke to enter the smoke hood 1, which can improve the oil smoke absorption efficiency without increasing the noise, and can also reduce the heat damage to the cooks in the high-temperature cooking area, thereby improving the user's cooking experience.

[0053] Figure 3 Shows Figure 2 A schematic cross-sectional view of an example purification module 5 is shown in FIG. Figure 4 Shows Figure 3 The structural diagram of the purification module 5 is shown in FIG. Figure 3 to Figure 4 As shown, the purification module 5 includes a mounting member 51 and a filter member 52. The mounting member 51 includes a panel abutting against the inner wall of the air guide channel 10. A plurality of panels are connected end to end in sequence to form a purification channel with an inlet and an outlet. A plurality of filters 52 are arranged at intervals in the purification channel, and the projections of all filters 52 in the inlet direction fully cover the inlet; and / or the projections of all filters 52 in the outlet direction fully cover the outlet, that is, all filters 52 form a filtering barrier that blocks the oil smoke from flowing to the outlet of the purification channel, and the filter member 52 has a breathable adsorption portion for allowing the oil smoke to flow through and adsorbing oil stains in the oil smoke.

[0054] In this embodiment, the filter element 52 has a plurality of through grooves 520 on its surface facing the inlet or outlet of the purification channel, and the through grooves 520 are filled with air-permeable adsorption materials to form the above-mentioned air-permeable adsorption portion. When the oil smoke flows through the purification channel, it can only flow from the air-permeable adsorption materials in the through grooves 520 of the filter element 52 to the outlet of the purification channel, and the oil in the oil smoke is adsorbed by the adsorption materials to achieve the purpose of purifying the oil smoke.

[0055] All the filters 52 form multiple layers of filter units in the purification channel that are arranged in sequence along the flow direction of the oil smoke, and each layer of the filter unit has at least one filter element 52. The filter elements 52 in two adjacent layers of the filter units are staggered to ensure that the oil smoke at each position in the purification channel can be filtered and purified at least once, thereby improving the purification effect.

[0056] For the convenience of description, the filter elements 52 on the same horizontal plane are defined as a layer of filter units. There can be one or two filter elements 52 in each layer of filter units. All filter elements 52 are arc-shaped, and the openings of the filter elements 52 in two adjacent layers of filter units face in opposite directions. Specifically, there are six layers of filter units in the purification channel. The first layer of filter unit 521 includes two filter elements 52 arranged at intervals, and the arc-shaped opening of the filter element 52 of the first layer of filter unit 521 faces downward; the second layer of filter unit 522 includes a filter element 52, the arc-shaped opening of the filter element 52 faces upward, and the filter element 52 at least partially blocks the interval between the two filter elements 52 of the first layer; the projections of all filter elements 52 in the first layer of filter unit 521 and the second layer of filter unit 522 at the inlet and outlet of the purification channel fully cover the inlet and the outlet; in addition, the third layer of filter unit 523 and the fifth layer of filter unit 525 are the same as the first layer of filter unit 521, and the fourth layer of filter unit 524 and the sixth layer of filter unit 526 are the same as the second layer of filter unit 522. When the oil smoke passes through the purification channel, the oil smoke can be fully filtered and purified under the action of the above-mentioned six-layer filter unit.

[0057] In addition, since the opening of the filter element 52 in the first filter unit 521 is downward, that is, the convex arc surface of the filter element 52 is upward, on the one hand, the contact area between the oil smoke and the filter element 52 can be increased, and the filtering effect on the oil smoke can be improved; on the other hand, the arc surface of the filter element 52 can also have a certain guiding effect on the flow direction of the oil smoke, so that the oil smoke can smoothly flow to the filter element 52 in the second filter unit 522. Since the opening of the filter element 52 in the second filter unit 522 is upward, on the one hand, the concave arc surface of the filter element 52 can store and accumulate a certain amount of oil stains to prevent the oil stains from continuing to flow downward with the oil smoke; on the other hand, the concave arc surface of the filter element 52 can generate a certain force on the oil smoke, so that the oil smoke flows back upward to the lower surface of the filter element 52 of the first filter unit 521. At this time, the filter element 52 of the first filter unit 521 can filter and purify the oil smoke again, and improve the purification effect. Similarly, the working principles of the third filter unit 523, the fourth filter unit 524, the fifth filter unit 525 and the sixth filter unit 526 are similar to those of the first filter unit 521 and the second filter unit 522, and are not described again here.

[0058] In this embodiment, all the filter elements 52 extend in the left-right direction, one end of all the filter elements 52 is connected to the left enclosure 511 of the mounting member 51, and the other end thereof is connected to the right enclosure 51 of the mounting member 51. In other embodiments, all the filter elements 52 may also extend in the front-back direction, one end of all the filter elements 52 is connected to the front enclosure 512 of the mounting member 51, and the other end thereof is connected to the rear enclosure 513 of the mounting member 51; or some of all the filter elements 52 extend in the left-right direction, and some extend in the front-back direction, which is not limited here.

[0059] In this embodiment, the left and right panels 511 and 513 of the mounting member 51 both have an oil groove 514 with an opening facing upwards, and the oil groove 514 is used to collect and store oil in the oil smoke, reduce the probability of the oil in the oil smoke flowing freely in the air guide channel 10, and facilitate the cleaning of the range hood 100. Further, the front panel 512 and the rear panel 513 of the mounting member 51 both have an oil guide groove 515 with an opening facing upwards, and the oil guide groove 515 is connected to the oil groove 514, so that the oil accumulated in the oil guide groove 515 can be concentrated and flowed into the oil groove 514, so as to realize the collection of the oil in the oil groove 514, which is convenient for subsequent cleaning. In addition, in order to facilitate the oil in the oil guide groove 515 to flow into the oil groove 514, the bottom surface of the oil guide groove 515 can be designed to be high in the middle and low on the left and right sides, so that the oil can flow into the oil grooves 514 on the left and right sides under the action of its own gravity.

[0060] In other embodiments, the oil groove 514 may be provided only on the left panel 511 of the mounting member 51, and the oil guide groove 515 may be provided on the front panel 512 and the rear panel 513 of the mounting member 51. Since the overall length of the mounting member 51 in the left-right direction is greater than its length in the front-back direction, the oil groove 514 may be provided on the left panel 511 and / or the right panel of the mounting member 51, and the function of the oil groove 514 may be integrated on the mounting member 51 without affecting the filtering effect of the filter element 52.

[0061] In other embodiments, the oil groove 514 may be provided on the front panel 512 and / or the rear panel 513 of the mounting member 51, and the oil guide groove 515 connected to the oil groove 514 may be provided on the left panel 511 and / or the right panel, so as to achieve the purpose of collecting and storing oil contaminants. It is understandable that as long as the oil groove 514 is provided on one of the panels of the mounting member 51, the purpose of collecting and storing oil contaminants can be achieved, and there is no limitation on the position of providing the oil groove 514.

[0062] Figure 5 Shows Figure 2 FIG. 5 is a cross-sectional view of another example of a purification module 5 . Figure 6 Shows Figure 2 A cross-sectional schematic diagram of another example of a purification module 5 is shown in FIG. Figure 5 to Figure 6 Combined with Figure 3 As shown, the number of filter elements 52 in each filter unit layer can be one, two, three, four, etc. Of course, it is understandable that the number of filter elements 52 in each filter unit layer can also be five, six, seven, eight, etc., which is not limited here.

[0063] like Figure 3 As shown, when there are two filter elements 52 in the filter unit, the two filter elements 52 are arranged in the same direction and in the same posture. Figure 5 As shown, when there are two filter elements 52 in the filter unit, the two filter elements 52 are arranged at intervals in different postures. When the filter element 52 is an arc-shaped filter element, the posture of the filter element 52 opening upward is the positive posture, and the posture of the filter element 52 opening downward is the negative posture, that is, the two filter elements 52 are arranged at intervals in different postures, one positive and one negative. Figure 6 As shown, when the number of filter elements 52 in the filter unit is three or four, when the filter element 52 is an arc-shaped filter element, the filter element 52 with its opening facing upward is a positive posture, and the filter element 52 with its opening facing downward is a negative posture, and the filter element 52 can be arranged regularly in a positive and negative manner. It is understandable that when the number of filter elements 52 in the filter unit is two or more, all the filter elements 52 can be arranged at intervals in different postures, which will not be described one by one here.

[0064] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
