[0032] The technical scheme of the utility model will be further illustrated below by combining with the drawings and through specific embodiments.

[0033] With the development of social economy and the gradual improvement of people's living standards, people pay more and more attention to the quality of life and home, especially more and more people pay attention to kitchen health, understand the kitchen fume, and the range hood as one of the indispensable kitchen appliances in modern family, can quickly suck the waste gas produced by the stove combustion and the oil fume produced in the cooking process, and discharge it outside, in order to achieve the purpose of purifying the kitchen environment. But part of the kitchen of the house does not reserve the public flue, and it is not convenient to discharge outside, so the demand of the internal exhaust type range hood is increasing.

[0034] As shown in Figure 1 and Figure 2 The embodiment provides a kind of kitchen appliance, which includes main body 1, main body 1 is equipped with smoke inlet 18 and smoke outlet, the inside of main body 1 is provided with flue gas passage 13 and fan 14, when fan 14 opens, negative pressure is generated in smoke inlet 18, flue gas generated in the cooking process can be sucked into flue gas passage 13 from smoke inlet 18 by fan 14, and the flue gas is discharged from smoke outlet after passing through fan 14.

[0035] In the prior art, in order to avoid the influence of the internal exhaust type range hood on the indoor air quality, the inhaled flue gas needs to be purified. Generally, an oil screen is arranged at the flue gas inlet 18 and the air inlet of the fan 14 to block and adsorb oil fume particles. The unadsorbed oil fume particles are thrown to the inner wall of the shell of the fan 14 by the centrifugal action of the impeller of the fan 14. Generally, the oil fume particles flow downward along the inner wall of the shell to the oil collecting box arranged at the bottom of the fan 14, thereby achieving the purification effect of the flue gas and avoiding the pollution of the indoor air.

[0036] However, after the range hood is used for a period of time, a large amount of oil droplets and particulate matter are deposited on the inside of the range hood, the shell of the fan 14 and the oil screen at the air inlet of the fan 14 to form oil stains. The oil stains have almost no flowability and thus cannot flow to the oil collecting box for collection, which easily affects the passability of the oil screen and also causes the weight of the impeller of the fan 14 to increase, thereby affecting the air volume of the fan 14, lowering the smoke suction effect, causing the indoor air quality to be poor and seriously affecting the user experience.

[0037] As shown in FIG. 1, Figures 2 to 4 To solve the above problems, the kitchen appliance provided by the embodiment further includes a purification assembly 2. The purification assembly 2 includes a purification piece 21 and a liquid storage groove 22. The liquid storage groove 22 is arranged below the flue gas inlet 18. A dissolving agent is arranged in the liquid storage groove 22. The dissolving agent is configured to be able to dissolve oil fume particles. The purification piece 21 is rotationally connected to the main body 1. The purification piece 21 is partially located below the liquid level of the dissolving agent. The highest point of the purification piece 21 is located at the rear side of the flue gas inlet 18.

[0038] When the range hood is turned on, the purification assembly 2 is also started. In the process of rotation of the purification piece 21, the purification piece 21 can dip the dissolving agent in the liquid storage groove 22. When the dissolving agent is rotated to the rear side of the flue gas inlet 18 along with the purification piece 21, the dissolving agent is blown away from the purification piece 21 by the flue gas entering from the flue gas inlet 18, flows along with the flue gas and mixes with the flue gas. Since the dissolving agent can dissolve oil fume particles, the oil fume particles will not deposit to form oil stains but will flow to the oil collecting box along with the dissolving agent, thereby preventing the oil screen from being blocked and avoiding the loss of the air volume of the fan 14 caused by the adhesion of oil stains to the impeller. The range hood can long-term guarantee the smoke suction capacity and can improve the purification effect of oil fume, avoid the pollution of indoor air and improve the user experience.

[0039] It is worth noting that the rear side of the flue gas inlet 18 refers to the downstream of the flue gas inlet 18 along the flue gas flow direction. The rear side of the flue gas inlet 18 can be the same direction as the rear side of the kitchen appliance or can be a different direction. The front side of the kitchen appliance refers to the side close to the user. The rear side of the kitchen appliance generally refers to the side abutting against the installation wall.

[0040] As shown in FIG. 1, Figure 4As shown, the purifying member 21 comprises a support member 211 and a foaming ring 212, one end of the support member 211 is connected with the foaming ring 212, the other end of the support member 211 is rotationally connected with the main body 1, in the rotation process of the support member 211, the foaming ring 212 can pass through the liquid storage groove 22 and dip the dissolving agent, and generate bubbles under the action of the flue gas at the rear side of the smoke inlet 18.

[0041] After the foaming ring 212 is immersed in the dissolving agent, the dissolving agent will form a film on the foaming ring 212, when the foaming ring 212 with the film moves to the rear side of the smoke inlet 18, the flue gas can make the film form bubbles, the bubbles can float and diffuse in the flue gas channel 13, so that the oil fume particles can be attached to the surface of the bubbles and gradually grow from small particles to large particles, which is beneficial to the settlement due to gravity, and realizes the purification effect of the flue gas.

[0042] It is worth noting that the dissolving agent is mixed and prepared by the foaming agent and water in a certain proportion, and the higher the proportion of the foaming agent, the larger the size of the snowflake-shaped foam sprayed, and the better the purification effect.

[0043] Further, the liquid level of the dissolving agent in the liquid storage groove 22 is greater than the diameter of the foaming ring 212, so that the foaming ring 212 can be completely immersed in the dissolving agent. That is, when the foaming ring 212 rotates to the lowest point, the dissolving agent can completely submerge the foaming ring 212, so as to ensure that a complete film can be formed on the foaming ring 212, which facilitates the foaming ring 212 to rotate to the rear side of the smoke inlet 18, and the film can generate bubbles when the flue gas blows through.

[0044] As shown, Figure 4 The purifying member 21 comprises a plurality of foaming rings 212, which are circumferentially spaced apart on the support member 211. When the purifying member 21 rotates, the plurality of foaming rings 212 can dip the dissolving agent in turn through the liquid storage groove 22, while ensuring that there is always a foaming ring 212 at the rear side of the smoke inlet 18, thereby realizing the effect of continuously generating bubbles and improving the purification effect.

[0045] In some embodiments, the rotation of the purifying member 21 can be completed by setting a motor, when the kitchen appliance starts, the motor also starts synchronously, thereby driving the purifying member 21 to rotate; in some embodiments, the rotation of the purifying member 21 can also be completed by the flue gas sucked into the smoke inlet 18, wherein the purifying member 21 is circumferentially spaced apart by a plurality of blades, the blades are inclined, and when the flue gas blows through the purifying member 21, the blades can drive the purifying member 21 to rotate.

[0046] In the embodiment, the dissolving agent flows in the storage tank 22, that is, the dissolving agent drives the purification element 21 to rotate by flowing. In order to facilitate the dissolving agent to drive the purification element 21, the rotation axis of the purification element 21 is perpendicular to the flowing direction of the dissolving agent. The structure can reduce the hardware structure, and avoid that the driving force provided by the flue gas is small and cannot make the purification element 21 overcome the resistance of the dissolving agent, so that the purpose of ensuring the stable rotation of the purification element 21 under the premise of energy saving and cost saving is achieved.

[0047] It can be understood that, in order to facilitate the purification element 21 to generate bubbles, the size of the purification element 21 along the axial direction needs to be designed to be small, which leads to that the flow of the dissolving agent cannot generate enough force on the purification element 21. Figure 4 As shown in the figure, in order to solve the above problem, the purification element 21 is provided with a plurality of baffles 213 which are arranged at intervals along the circumferential direction, the plane where the baffle 213 is located is arranged at an angle with the flowing direction of the dissolving agent, and the angle θ satisfies 0° < θ ≤ 90°.

[0048] The structure can make the dissolving agent generate a pushing force on the purification element 21 through the baffle 213, and ensure that the flow of the dissolving agent can make the purification element 21 rotate. Preferably, the angle θ is 90°, so that the acting direction of the pushing force is perpendicular to the rotation axis of the purification element 21, effectively driving the rotation of the purification element 21, and ensuring that the purification element 21 can continuously generate bubbles.

[0049] In the embodiment, the baffle 213 can be arranged on the foaming ring 212, and each foaming ring 212 is provided with a plurality of baffles 213 at equal intervals, so as to ensure that the driving force of the dissolving agent on the purification element 21 is increased.

[0050] As shown in the figure, Figure 2 and Figure 5 In order to make the dissolving agent flow continuously, in the embodiment, the purification assembly 2 further comprises a liquid storage tank 23 and a pump body 24, the dissolving agent is arranged in the liquid storage tank 23, the liquid outlet and the liquid inlet of the liquid storage tank 23 are communicated with the storage tank 22, and the pump body 24 is configured to drive the dissolving agent to flow circularly in the liquid storage tank 23 and the storage tank 22.

[0051] The pump body 24 can pump the dissolving agent from the liquid storage tank 23 into the storage tank 22, and the dissolving agent in the storage tank 22 can flow back to the liquid storage tank 23, so as to complete the circulation of the dissolving agent, make the dissolving agent in the storage tank 22 flow, and ensure that the liquid level of the dissolving agent in the storage tank 22 is basically unchanged, which can ensure the rotation of the purification element 21 and the continuous generation of bubbles by the purification element 21.

[0052] It is worth mentioning that the kitchen appliance mentioned above can be a range hood or an integrated cooker with a range hood function, both of which can use the purification assembly 2 to purify the smoke inhaled, thereby optimizing the indoor environment.

[0053] In this embodiment, the kitchen appliance is taken as an integrated cooker for illustration.

[0054] As shown in Figure 1 and Figure 2 , the main body 1 of the integrated cooker includes a head 12 and a panel 11, the head 12 is arranged on the panel 11, and a burner (not shown in the figure) is also arranged on the panel 11, which is used for cooking. In order to facilitate the user to inhale the smoke when cooking through the burner, the smoke inlet 18 is opened at the front end of the head 12, and the purification piece 21 is rotationally arranged in the head 12, which can generate bubbles in the head 12 when the smoke enters the head 12.

[0055] In order to improve the efficiency of cooking and enable the user to perform multiple cooking operations at the same time, at least two burners are arranged on the panel 11, and the purification assembly 2 includes a purification piece 21 corresponding to each burner, and along the front-rear direction of the integrated cooker, the purification piece 21 is located behind the corresponding burner.

[0056] Each burner produces smoke when cooking, which is inhaled into the head 12 along the front-rear direction of the integrated cooker through the smoke inlet 18, and at this time the smoke passes through the corresponding purification piece 21 behind the burner, so the purification piece 21 can directly purify the smoke, greatly improving the effect of purifying the smoke.

[0057] It is worth mentioning that the liquid storage tank 22 has two communication ports, one of which communicates with the liquid outlet of the liquid storage tank 23, and the other of which communicates with the liquid inlet of the liquid storage tank 23, and the purification piece 21 is located between the two communication ports of the liquid storage tank 22 to ensure that the flow of the dissolving agent can drive all the purification pieces 21 to rotate.

[0058] It can be understood that since the pump body 24 needs to work continuously, in order to prevent oil smoke particles from adhering to the surface of the oil pump and affecting its normal use, the pump body 24 and the liquid storage tank 23 need to be arranged outside the main body 1. Generally speaking, the integrated cooker needs to be installed against the wall to save space and improve aesthetics.

[0059] As shown in Figure 2As shown, the main body 1 further comprises a first back plate 15, a horizontal plate 16 and a second back plate 17, the first back plate 15 is arranged at the rear end of the horizontal plate 16 and abuts against the installation wall, the second back plate 17 is arranged at the front end of the horizontal plate 16 and is located below the horizontal plate 16, and the fan 14 is arranged in front of the second back plate 17, when the fan 14 is started, the flue gas enters the head 12 and then enters the fan 14 after passing through the first back plate 15 and the horizontal plate 16 in turn, and is then blown out by the fan 14 and discharged through the smoke outlet.

[0060] It can be understood that there is an installation space between the second back plate 17, the horizontal plate 16 and the installation wall, the pump body 24 and the liquid storage tank 23 are arranged in the installation space, so as to ensure that the working environment of the pump body 24 and the liquid storage tank 23 is relatively clean, thereby reducing the number of maintenance and cleaning and prolonging the service life.

[0061] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range can be changed, and the content of the specification should not be understood as a limitation of the present application.
