[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0051] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0053] The combination stove will produce oil smoke during use, so the combination stove needs to exhaust the oil smoke. In addition to oil mist particles, the air also contains water vapor and other harmful substances. In the related art, a filter device is set on the air inlet path of the combination stove, and the filter device plays a role of coarse filtering. When the air passes through the filter device, some oil mist particles will adhere to the filter device, and water vapor will also condense on the filter device when encountering the filter device. After long-term use, the filter device will weaken the filtering performance due to filtering dirt, so it is necessary to clean the filter device regularly. In order to facilitate the user to disassemble and assemble the filter device, the filter device will be provided with a handle. When disassembling and assembling the filter device, the user will hold the handle to remove the filter device. Although such a handle is convenient for the user, it will hinder the installation of other components of the combination stove. In order to avoid the handle hindering the installation of other components, the thickness of the combination stove needs to be increased. In order to solve the above-mentioned problems, the present application discloses a filter device, and the filter device will be described in detail in conjunction with the combination stove below.

[0054] Specifically, Figures 1 to 6 ,as well as Figures 11 to 13 As shown, in some embodiments, the combination stove includes a body 1000 , a cover plate 2000 , a fan 3000 and a filter device 6000 .

[0055] The body 1000 serves as a load-bearing frame in the combination stove and is used to install various components to maintain the overall shape of the combination stove.

[0056] The cover plate 2000 is mounted on the body 1000 to form the top surface of the combination stove. When the combination stove is mounted on the cabinet, the cover plate 2000 is exposed, that is, the cover plate 2000 is within the user's field of vision and the body 1000 is hidden in the cabinet. The cover plate 2000 is generally in the shape of a flat plate, and can be made of glass, for example. The cover plate 2000 is provided with an opening 2100, and the opening 2100 passes through the upper surface and the lower surface of the cover plate 2000. The left side of the opening 2100 is the left cooking zone 2210, and the right side of the opening 2100 is the right cooking zone 2220. An electromagnetic heating device is provided in the body 1000 corresponding to the left cooking zone 2210, and an electromagnetic heating device is also provided in the body 1000 corresponding to the right cooking zone 2220 (of course, a burner that uses combustible gas for combustion can also be provided).

[0057] Continue to combine Fig.19 As shown, the fan 3000 includes a volute 3100, an impeller 3400 and a motor. The volute 3100 includes a lower volute 3120 and an upper volute 3110, the motor is mounted on the lower volute 3120, the impeller 3400 is a centrifugal wind wheel and is mounted on the lower volute 3120 and is connected to the motor drive, the upper volute 3110 and the lower volute 3120 are connected to cover the impeller 3400, an air duct 3500 is formed between the upper volute 3110 and the lower volute 3120, the impeller 3400 is located in the air duct 3500, the upper volute 3110 is provided with an air inlet 3111 communicating with the air duct 3500, an air outlet 3121 communicating with the air duct 3500 is formed between the upper volute 3110 and the lower volute 3120, and the fan 3000 is fixed to the fuselage 1000 through the upper volute 3110.

[0058] The motor in the fan 3000 works to drive the impeller 3400 to rotate and form negative pressure. Under the action of pressure, the outside air will enter the fuselage 1000 from the opening 2100 of the cover 2000, and then enter the air duct 3500 through the air inlet 3111, and then be discharged through the air outlet 3121. The path of the air flowing from the opening 2100 of the cover 2000 to the air inlet 3111 of the fan 3000 can be regarded as the air inlet path.

[0059] The filter device 6000 includes a mounting frame 6200, the mounting frame 6200 is provided with a filter 6100, and the filter device 6000 is provided on the air inlet path. When the air flows through the filter device 6000, the oil mist particles in the air will adhere to the filter 6100, and the water vapor in the air will condense when it encounters the filter 6100. In this way, the filter device 6000 will filter various dirt after long-term use, so the filter device 6000 needs to be disassembled for cleaning.

[0060] It is understandable that the filter device 6000 is detachably arranged in the combination stove through the mounting frame 6200, and the user can disassemble the filter device 6000 and take out the filter device 6000 from the opening 2100 to clean the filter device 6000. After cleaning the filter device 6000, the filter device 6000 can be put back to the air inlet path through the opening 2100.

[0061] The detachable setting of the mounting frame 6200 can realize the detachable setting of the entire filter device 6000. When the user disassembles the mounting frame 6200, since the filter 6100 is set on the mounting frame 6200, the filter 6100 can be disassembled and installed along with the mounting frame 6200. The detachable setting of the mounting frame 6200 has multiple ways, such as being fixed on the air inlet path of the fan 3000 by snap fastening, being fixed on the air inlet path of the fan 3000 by magnetic attraction, or being fixed on the air inlet path of the fan 3000 by gravity support. The filter 6100 can be set on the mounting frame 6200 in multiple ways, such as screw connection, snap connection, bonding, etc.

[0062] The mounting frame 6200 is provided with a handle 6300, which is movably connected to the mounting frame 6200, so that the handle 6300 can have a storage state and an unfolded state relative to the mounting frame 6200. The so-called storage state means that the space occupied by the handle 6300 is reduced, and the handle 6300 is as close to the mounting frame 6200 as possible, so that when the filter device 6000 is installed on the combination stove, the handle 6300 will not hinder the installation of other components. The so-called unfolded state means that the handle 6300 will increase the space occupied, and is separated from the mounting frame 6200 as much as possible, and does not fit the mounting frame 6200, so that a gripping space is formed between the handle 6300 and the mounting frame 6200. Since there is no obstruction from the mounting frame 6200, it is convenient for the user to reach into the gripping space and grip the handle 6300, thereby lifting the entire filter device 6000.

[0063] For example, with the state of the combined stove installed in the cabinet as a reference, the grille 5000 will be installed above the filter device 6000. When the filter device 6000 does not need to be removed, the handle 6300 is in the storage state, so that the grille 5000 can be as close to the filter device 6000 as possible, so that the size of the combined stove in the height direction (i.e., the up and down direction when the combined stove is installed in the cabinet) is compressed as much as possible, so that the overall combined stove can be made thinner and reduce the space occupied in the cabinet. When the filter device 6000 needs to be removed, the grille 5000 is first detached from the opening 2100, and then the handle 6300 is controlled to switch from the storage state to the unfolded state. Since the weight of the handle 6300 is much smaller than that of the entire filter device 6000, the user can easily switch the handle 6300 to the unfolded state. When the handle 6300 is in the unfolded state, the user can hold the handle 6300 to lift the filter device 6000 from the opening 2100.

[0064] From the above, it can be seen that by designing the handle 6300 of the filter device 6000 to be movable, the handle 6300 has a storage state and an unfolded state relative to the mounting frame 6200. When the handle 6300 is in the storage state, it can reduce the space occupied, and when it is in the unfolded state, it is convenient for the user to grab it, which can reduce the overall thickness of the combination stove and does not affect the user's separation of the filter device 6000 from the combination stove.

[0065] like Figures 15 to 18 As shown, in some embodiments, the handle 6300 can be moved along the direction of gravity to be in a stored state, and the handle 6300 can be moved in a direction opposite to gravity to be in an expanded state, which makes it convenient for the user to lift and reset the handle 6300.

[0066] Specifically, with the state of the combined stove installed in the cabinet as a reference, the handle 6300 moves in the direction of gravity, that is, from top to bottom, and the handle 6300 moves in the direction against gravity, that is, from bottom to top. Since the mounting frame 6200 needs to install the filter 6100, the mounting frame 6200 needs to occupy a certain height space along the height direction of the filter device 6000 (the up and down direction in the figure), and the handle 6300 is designed to be movable along the up and down direction. When the handle 6300 is in the storage state, the height space occupied by the mounting frame 6200 can be fully utilized, and even hidden in the mounting frame 6200.

[0067] In addition, when the user removes the filter device 6000 from the combination stove, the user needs to stand in front of the cabinet, and the user only needs to lift the handle 6300 from the bottom to the top to switch the handle 6300 from the storage state to the unfolded state, thereby holding the handle 6300, which is convenient and quick, and does not require the user to perform too many operations. When the user installs the filter device 6000 back to the combination stove, the user only needs to install the filter device 6000 in place, and the user can release the handle 6300, and the handle 6300 will move from the top to the bottom under the action of gravity and switch from the unfolded state to the storage state, and the user does not need to operate the handle 6300 to move from the unfolded state to the storage state, thereby improving the user experience.

[0068] like Figures 9 to 14 ,as well as Fig.16 and Fig.18 As shown, in some embodiments, the handle 6300 has a grip portion 6310, which is used for a user to grip. When the handle 6300 is in the stored state, the distance between the grip portion 6310 and the mounting frame 6200 is h1. When the handle 6300 is in the unfolded state, the distance between the grip portion 6310 and the mounting frame 6200 is h2, satisfying that h2 is greater than h1.

[0069] Specifically, the gripping portion 6310 is a portion for the user to hold. When the user disassembles the filter device 6000, the user's hand can hold the gripping portion 6310. For example, the gripping portion 6310 is in the shape of a long rod. With reference to the state in which the combined stove is installed in the cabinet, the gripping portion 6310 is horizontally arranged. Along the height direction of the filter device 6000, that is, the up and down direction shown in the figure, when the handle 6300 is in the storage state, the distance between the gripping portion 6310 and the mounting frame 6200 is h1, for example, h1 can be 0, 0.5 cm, 1 cm, 1.5 cm, etc., and when the handle 6300 is in the unfolded state, the distance between the gripping portion 6310 and the mounting frame 6200 is h2, for example, h2 can be 2 cm, 3 cm, 5 cm, etc. Thus, when the handle 6300 is in the unfolded state, a gripping space can be formed between the handle 6300 and the mounting frame 6200, and the gripping space can be inserted into the user's hand to facilitate the user to grip the gripping portion 6310, so that the user can lift the entire filter device 6000 by lifting the gripping portion 6310. When the handle 6300 is in the stored state, the gripping space becomes smaller or even disappears, reducing the space occupied by the handle 6300.

[0070] The formation and disappearance of the gripping space between the handle 6300 and the mounting frame 6200 can be achieved by moving the handle 6300 in the up-down direction, or by rotating the handle 6300. The movement of the handle 6300 in the up-down direction can be referred to the aforementioned embodiment, and will not be repeated here. For the rotation operation of the handle 6300, for example, the two ends of the extension direction of the handle 6300 and the mounting frame 6200 can be rotatably connected, and when the user rotates the handle 6300 to a vertical state, a gripping space can be formed between the handle 6300 and the mounting frame 6200, and when the user detaches from the handle 6300, the handle 6300 can be rotated under the action of gravity to rest on the mounting frame 6200, thereby reducing or eliminating the gripping space.

[0071] like Fig. 9 and Fig.10 As shown, in some embodiments, the handle 6300 includes a sliding portion 6320 and a gripping portion 6310 , and the handle 6300 is slidably connected to the mounting frame 6200 via the sliding portion 6320 , so that the handle 6300 has an unfolded state and a retracted state relative to the mounting frame 6200 .

[0072] Specifically, the handle 6300 may be an integrally formed structure, for example, the sliding portion 6320 and the gripping portion 6310 are formed by integral injection molding. The handle 6300 may also be a non-integrated structure, for example, the sliding portion 6320 and the gripping portion 6310 are prepared separately, and the sliding portion 6320 and the gripping portion 6310 are fixed together by screwing, bonding, welding, etc. The portion of the handle 6300 for the user to hold is regarded as the gripping portion 6310, and the portion for slidably connecting with the mounting frame 6200 is regarded as the sliding portion 6320. For example, the handle 6300 is integrally formed by injection molding, and the gripping portion 6310 and the sliding portion 6320 are both in the shape of a long rod, the gripping portion 6310 is arranged horizontally, and the sliding portion 6320 is arranged vertically, and a right angle is formed between the gripping portion 6310 and the sliding portion 6320.

[0073] The sliding part 6320 and the mounting frame 6200 are slidably connected, that is, the sliding part 6320 has a certain movable stroke relative to the mounting frame 6200. If the cooperation between the sliding part 6320 and the mounting frame 6200 is not intentionally removed, the sliding part 6320 will not be separated from the mounting frame 6200 within the limit of the movable stroke. The handle 6300 is used to move up and down for illustration. When the user holds the grip 6310, the grip 6310 can drive the sliding part 6320 to move relative to the mounting frame 6200. When the sliding part 6320 moves to the limit, the sliding part 6320 and the mounting frame 6200 are mutually limited and cannot be separated, so that the sliding part 6320 is lifted by the user. When the user does not hold the grip 6310, the grip 6310 is placed on the mounting frame 6200 under the action of gravity.

[0074] Furthermore, if Fig.14 As shown, in some embodiments, in order to more conveniently lift the filter device 6000 , sliding portions 6320 are provided at both ends of the extending direction of the gripping portion 6310 .

[0075] Specifically, the holding portion 6310 is in the shape of a long rod, and sliding portions 6320 are respectively provided at both ends of the length direction of the holding portion 6310. The handle 6300 as a whole forms an "N"-shaped structure. When the user lifts the holding portion 6310, the force is transmitted from the holding portion 6310 to the sliding portion 6320, and then transmitted from the sliding portion 6320 to the mounting frame 6200. Sliding portions 6320 are respectively provided at the opposite ends of the holding portion 6310, so that the force acting on the mounting frame 6200 through the sliding portion 6320 will be more evenly distributed. In this way, the extension range of the holding portion 6310 can be designed to be larger, thereby forming a larger holding space between the mounting frame 6200, making it convenient for the user to reach into the holding space and hold the holding portion 6310. In addition, because the sliding parts 6320 at both ends of the gripping part 6310 generate a more even force on the mounting frame 6200, when the handle 6300 is lifted, the handle 6300 is not easily deflected and deformed relative to the mounting frame 6200, thereby preventing the handle 6300 from breaking during the lifting process.

[0076] Specifically, Fig.10 and Fig.14 As shown, in some embodiments, one of the sliding part 6320 and the mounting frame 6200 is provided with a sliding protrusion 6321, and the other is provided with a sliding groove 6214. The mutual cooperation between the sliding protrusion 6321 and the sliding groove 6214 realizes a slidable connection between the sliding part 6320 and the mounting frame 6200, thereby realizing the storage state and the unfolded state of the handle 6300 relative to the mounting frame 6200.

[0077] The mounting frame 6200 is provided with a slide groove 6214, and the handle 6300 is provided with a slide protrusion 6321 for detailed description. The slide groove 6214 is extended in the up-down direction and has a certain height. When the handle 6300 is mounted on the mounting frame 6200, a force is applied to the handle 6300, so that the handle 6300 undergoes a certain elastic deformation, thereby aligning the slide protrusion 6321 with the slide groove 6214 and embedding it into the slide groove 6214. After the handle 6300 recovers its deformation, the slide protrusion 6321 is stuck in the slide groove 6214 and cannot be separated. In the process of switching the handle 6300 from the storage state to the unfolded state, the slide protrusion 6321 moves along the slide groove 6214 until the slide protrusion 6321 is stuck to the top of the slide groove 6214, so that the mounting frame 6200 can be separated from the combination stove as the handle 6300 is lifted. When the handle 6300 is switched from the unfolded state to the retracted state, the sliding protrusion 6321 moves along the sliding groove 6214 toward the bottom end of the sliding groove 6214 until the sliding protrusion 6321 and the bottom end of the sliding groove 6214 abut against each other or until the gripping portion 6310 is placed on the mounting frame 6200. The sliding groove 6214 and the sliding protrusion 6321 cooperate with each other to achieve sliding cooperation between the handle 6300 and the mounting frame 6200, which is simple in structure, stable and reliable.

[0078] Furthermore, in order to further reduce the space occupied by the grip portion 6310 and make it more convenient for the user to hold the grip. Fig.15 and Fig.16 As shown, in some embodiments, when the handle 6300 is in the storage state, the grip portion 6310 is lower than the upper surface of the mounting frame 6200.

[0079] Specifically, a horizontal plane is defined along the height direction of the filter device 6000, that is, the up-down direction shown in the figure. The horizontal plane moves from top to bottom until it just touches the mounting frame 6200. The corresponding part of the mounting frame 6200 is regarded as the upper surface, even if the corresponding part of the mounting frame 6200 forms a tip. The mounting frame 6200 needs to be used to install the filter 6100, so the mounting frame 6200 has a certain height along the up-down direction. When the handle 6300 is in the storage state, it is lower than the upper surface of the mounting frame 6200, so as to achieve the effect of hiding in the mounting frame 6200. When the grille 5000 is set above the filter device 6000, the grille 5000 can be as close to the filter device 6000 as possible, and even a part of the grille 5000 is embedded in the mounting frame 6200, so that the space of the combined stove can be compressed as much as possible, and the combined stove can be made thin and light.

[0080] In some embodiments, Fig.15 and Fig.16 As shown, when the handle 6300 is in the storage state, the sliding portion 6320 is higher than the lower surface of the mounting frame 6200 .

[0081] Specifically, a horizontal plane is defined along the height direction of the filter device 6000, that is, the up-down direction shown in the figure. The horizontal plane moves from bottom to top until it just touches the mounting frame 6200. The corresponding part of the mounting frame 6200 is regarded as the lower surface, even if the corresponding part of the mounting frame 6200 forms a tip. It can also be regarded as the lower surface. When the filter device 6000 is installed in the combination stove, it will be embedded in the body 1000. When the handle 6300 is in the storage state, the sliding part 6320 is higher than the lower surface of the mounting frame 6200. In this way, the handle 6300 is completely hidden in the mounting frame 6200 when it is in the storage state, that is, it is not exposed from the mounting frame 6200 in the up-down direction. In this way, the up-down space occupied by the mounting frame 6200 is maximized, and the setting of the handle 6300 is reduced to prevent obstacles to other components of the combination stove.

[0082] Furthermore, if Fig.17 and Fig.18 As shown, in some embodiments, when the handle 6300 is in the unfolded state, the grip portion 6310 is higher than the upper surface of the mounting frame 6200. Along the height direction of the filter device 6000, that is, the up-down direction shown in the figure, the grip portion 6310 protrudes from the mounting frame 6200, so that the space between the grip portion 6310 and the mounting frame 6200 can be increased as much as possible, so that the user can hold the grip portion 6310 conveniently.

[0083] like Fig.14 As shown, in some embodiments, the grip portion 6310 is provided with a lifting portion 6311. When the handle 6300 is in the storage state, the grip portion 6310 is as close to the mounting frame 6200 as possible. In order to facilitate the user to lift the grip portion 6310, a lifting portion 6311 is provided on the grip portion 6310. The user can pinch the lifting portion 6311 and lift it upward for a certain distance to form a gripping space between the grip portion 6310 and the mounting frame 6200, so that the user's hand can be inserted into the gripping space.

[0084] like Fig.13 and Fig.16 As shown, in some embodiments, the mounting frame 6200 is provided with a first ventilation hole 6220 , the filter 6100 covers the first ventilation hole 6220 , and the gripping portion 6310 spans across the first ventilation hole 6220 .

[0085] Specifically, when the fan 3000 is working, it can drive air to pass through the filter device 6000. In order to further avoid the obstruction of the air by the mounting frame 6200, a first ventilation hole 6220 is set on the mounting frame 6200. After passing through the filter 6100, the air can then pass through the first ventilation hole 6220 and enter the fan 3000. In this way, there is no need to change the air flow path, and the resistance to air flow is reduced. At the same time, the internal structure of the combination stove can be simplified, reducing the design difficulty.

[0086] The filter 6100 is installed on the portion of the mounting frame 6200 surrounding the first ventilation hole 6220, so that the mounting frame 6200 can better support the filter 6100, so that the filter 6100 covers the first ventilation hole 6220 to prevent air leakage.

[0087] The gripping portion 6310 spans across the first ventilation hole 6220 . When the user lifts the gripping portion 6310 , the force exerted by the gripping portion 6310 on the mounting frame 6200 is more evenly distributed, thereby making the filter device 6000 easier to disassemble.

[0088] Furthermore, if Fig.16 As shown, in some embodiments, in some embodiments, the mounting frame 6200 includes an inner wall 6213 and an outer wall 6211, the inner wall 6213 is arranged to form a first ventilation hole 6220, the handle 6300 is movably connected to the inner wall 6213, the outer wall 6211 is arranged around the inner wall 6213 to form a liquid collecting tank 6210 between the inner wall 6213, and the filter net 6100 is arranged to tilt to guide the filtrate into the liquid collecting tank 6210.

[0089] Specifically, the filter material may be condensed water or an oil-water mixture (detailed description will be given taking condensed water as an example). When the fan 3000 is working, the air will pass through the filter 6100, so that the water vapor in the air will condense into water droplets on the filter 6100, and the water droplets will separate from the filter 6100 and fall into the liquid collecting tank 6210 under the action of the airflow and gravity. The user can hold the handle 6300 to disassemble the filter device 6000, and take out the filter device 6000 from the opening 2100, so as to pour out the condensed water in the liquid collecting tank 6210, and perform deep cleaning on the filter device 6000. After cleaning the filter device 6000, the grip portion 6310 can be held and the filter device 6000 can be placed back on the air inlet path through the opening 2100. Of course, the liquid collecting tank 6210 can also be provided with a drain port to directly discharge the condensed water into the liquid collecting cup of the combined stove.

[0090] The handle 6300 is movably connected to the inner wall 6213 , for example, the handle 6300 can slide with the inner wall 6213 through the sliding part 6320 , thereby avoiding setting the handle 6300 on the outer wall 6211 and affecting other components, that is, the handle 6300 is completely hidden in the mounting frame 6200 .

[0091] Generally speaking, the filter device 6000 is arranged above the air inlet 3111 of the fan 3000. If the filter mesh 6100 is placed horizontally, then in order for the liquid collection tank 6210 to collect condensed water, the liquid collection tank 6210 needs to be arranged directly below the filter mesh 6100 and above the air inlet 3111, and the size needs to be adapted to the filter mesh 6100. In this way, the air flow will be blocked by the liquid collection tank 6210, and the air needs to avoid the liquid collection tank 6210 to enter the air inlet 3111, which will increase the resistance to air flow, increase wind noise and reduce the suction of the fan 3000.

[0092] Therefore, the above problem is solved by setting the filter 6100 in an inclined manner. It can be understood that the inclined setting is based on the state that the combined stove is installed in the cabinet. In this state, the filter 6100 is inclined relative to the horizontal plane, and the arrangement of the filter device 6000 and the fan 3000 mentioned above is also based on the state that the combined stove is installed in the cabinet. By setting the filter 6100 in an inclined manner, the condensed water condensed on the filter 6100 will flow along the filter 6100 from the top of the filter 6100 to the bottom of the filter 6100. The sump 6210 only needs to be set at the corresponding position at the bottom of the filter 6100 to receive the condensed water, and does not need to be set to the same size as the filter 6100 and placed directly below the filter 6100 to receive the condensed water. In this way, most of the air will not encounter the obstruction of the sump 6210. The filter 6100 is set in this way, so that the sump 6210 can both receive the condensed water and not cause excessive obstruction to the flow of air.

[0093] The liquid collecting tank 6210 is designed in an annular shape, that is, the liquid collecting tank 6210 is arranged around the filter screen 6100, and a plurality of filter screens 6100 can be provided accordingly, so that condensed water can be collected from multiple directions, thereby improving the condensation efficiency of water vapor. In addition, since the liquid collecting tank 6210 is connected in an annular shape, the condensed water collected in various places can be gathered together for easy cleaning.

[0094] Combination Fig.16 As shown, the bottom of the filter screen 6100 is located above the bottom of the liquid collecting tank 6210, so as to avoid liquid accumulation on the filter screen 6100, which makes it difficult to clean the filter screen 6100.

[0095] If the bottom of the filter 6100 is connected to the bottom of the liquid collecting tank 6210, when the condensed water on the filter 6100 flows to the liquid collecting tank 6210, the condensed water will soak the bottom of the filter 6100, and will form an enrichment of dirt at the intersection of the filter 6100 and the water surface of the condensed water, that is, the intersection of the filter 6100 and the water surface is easy to accumulate dirt and become difficult to clean. In addition, when the amount of condensed water reaches a certain level, it will cover part of the filter 6100, thereby reducing the condensation area of ​​the filter 6100, thereby making the condensation effect of the filter 6100 worse. Therefore, by positioning the bottom of the filter 6100 above the bottom of the liquid collecting tank 6210, that is, the two are designed not to contact, the condensed water can flow down from the filter 6100 to the liquid collecting tank 6210, avoiding the condensed water soaking the filter 6100 and reducing the condensation area of ​​the filter 6100, and continuously achieving efficient condensation of water vapor in the air.

[0096] Combination Figure 3 and Fig.14 As shown, in some embodiments, the filter nets 6100 include two, and of course may also include three, four, or more. The two filter nets 6100 form an inverted V-shaped structure, which can increase the filtration area and improve the filtration efficiency within a limited lateral space.

[0097] Specifically, the two filters 6100 are respectively the second filter 6120 and the first filter 6110. The second filter 6120 and the first filter 6110 are arranged adjacent to each other to form an inverted V-shaped structure. The adjacent arrangement here means that the two are close to each other, and can be fitted or separated by a certain gap. The second filter 6120 and the first filter 6110 cooperate with each other to form an inverted V-shaped structure arranged side by side in the left and right directions, which can reduce the occupation of the horizontal space of the combination stove and increase the filtration area. In addition, the first filter 6110 and the second filter 6120 have different inclination directions, thereby reducing the occupation of the vertical space while ensuring the same filtration area.

[0098] The first filter 6110 and the second filter 6120 are in an inverted V-shaped structure, so that the first filter 6110 is tilted toward the left cooking zone 2210, and the second filter 6120 is tilted toward the right cooking zone 2220. Generally, the combination stove is provided with a grille 5000, and the grille 5000 guides the air in the left cooking zone 2210 to flow toward the first filter 6110, and the flow direction is as perpendicular to the first filter 6110 as possible, so as to effectively improve the filtration efficiency of the air from the left cooking zone 2210 and reduce the flow resistance; in addition, the grille 5000 can also guide the air in the right cooking zone 2220 to flow toward the second filter 6120, and the flow direction is as perpendicular to the second filter 6120 as possible, so as to improve the filtration efficiency of the air from the right cooking zone 2220 and reduce the flow resistance.

[0099] The holding portion 6310 is disposed between the first filter 6110 and the second filter 6120 , and the air flows mainly through the first filter 6110 and the second filter 6120 , so the setting of the holding portion 6310 does not cause excessive obstruction to the air flow.

[0100] like Figures 5 to 8 As shown, in some embodiments, the combination stove also includes a connecting member 4000, which is disposed on the lower surface of the cover plate 2000 and exposed at the opening 2100, and the filter device 6000 is disposed at the opening 2100 and supported on the connecting member 4000 to achieve a detachable connection of the filter device 6000.

[0101] The filter device 6000 is arranged at the opening 2100, that is, the filter device 6000 can roughly cover the opening 2100 when installed, so that air can pass through the filter device 6000. By arranging the connector 4000 in the cover plate 2000, the connector 4000 is exposed at the opening 2100, and the filter device 6000 is supported in the connector 4000 when it is arranged at the opening 2100. In this way, it is only necessary to ensure that the position of the connector 4000 when it is arranged on the cover plate 2000 is accurate, and the position relationship of the filter device 6000 is not affected by the fuselage 1000. When the filter device 6000 is arranged at the opening 2100 and supported by the connector 4000, the mutual matching between the filter device 6000 and the air inlet path can be ensured, and a gap is not easily formed between the filter device 6000 and the opening 2100, thereby avoiding air leakage.

[0102] If the connecting member 4000 is not arranged on the cover plate 2000 but on the fuselage 1000, then when installing the cover plate 2000 and the fuselage 1000, it is necessary to ensure the precise positioning between the cover plate 2000 and the fuselage 1000 to avoid the displacement of the connecting member 4000 relative to the opening 2100 of the cover plate 2000, resulting in position deviation in the installation of the filter device 6000. It seems that this installation method greatly increases the manufacturing difficulty.

[0103] In addition, the filter device 6000 is supported on the connector 4000, for example, the filter device 6000 directly supports the connector 4000 by gravity, so that the filter device 6000 and the connector 4000 are detachably connected. The filter device 6000 is supported on the connector 4000 by gravity. When the air flows, the force applied by the air to the filter device 6000 tightly presses the filter device 6000 on the connector 4000, and the filter device 6000 will not shake and cause abnormal noise when the air flows. The user inserts the filter device 6000 from the outside of the cover plate 2000 into the opening 2100 by holding the gripping portion 6310, and the filter device 6000 can be supported on the connector 4000 under the action of gravity. Similarly, when disassembling, the user can lift the filter device 6000 from the opening 2100 by holding the gripping portion 6310, so that the user is convenient for disassembly and assembly, and the use experience is improved.

[0104] It can be understood that the connection member 4000 is exposed in the opening 2100 , which means that when the combination stove is installed in the cabinet, when looking down from directly above the combination stove, part of the connection member 4000 can be seen to appear within the range enclosed by the opening 2100 .

[0105] The connector 4000 is disposed on the lower surface of the cover plate 2000 so as to be hidden and not protrude from the upper surface of the cover plate 2000, thereby not damaging the aesthetics of the cover plate 2000. In addition, since the lower surface of the cover plate 2000 can provide sufficient space for the connector 4000 to be fixed, there are more connection methods that can be adopted between the connector 4000 and the lower surface of the cover plate 2000, and the two are easier to fix. It is only necessary to ensure that when the connector 4000 is fixed to the lower surface of the cover plate 2000, part of the connector 4000 is exposed at the opening 2100, so that when the filter device 6000 is inserted into the opening 2100 from the outside of the cover plate 2000 and embedded in the fuselage 1000, the connector 4000 can support the filter device 6000.

[0106] The connector 4000 can be integrally formed by plastic injection molding, and has a first connector 4100 and a second connector 4200. By using plastic material to mold the connector 4000, the connector 4000 has the advantages of light weight and high toughness. When the combination stove is installed in the cabinet, looking from top to bottom, the part hidden in the cover plate 2000 can be regarded as the first connector 4100, and the part exposed in the opening 2100 can be regarded as the second connector 4200.

[0107] The connecting member 4000 can be a separate component and fixed to the lower surface of the cover plate 2000 by an additional connection method. There are various connection methods. For example, the first connecting part 4100 and the lower surface of the cover plate 2000 can be connected by bonding, welding, or screwing. The second connecting part 4200 is used to support the filtering device 6000.

[0108] like Fig.14 As shown, the mounting frame 6200 has an inner wall 6213, an outer wall 6211 and a bottom wall 6212, the bottom wall 6212 is located between the inner wall 6213 and the outer wall 6211, the outer wall 6211, the bottom wall 6212 and the inner wall 6213 are together arranged to form a liquid collecting tank 6210, when the filter device 6000 is mounted to the opening 2100, the outer wall 6211 of the mounting frame 6200 is supported on the connecting member 4000 (the second connecting portion 4200), thus achieving the positioning of the filter device 6000. By providing the mounting frame 6200 with the inner wall 6213 and the outer wall 6211, not only the condensed water is collected, but also the handle 6300 and the mounting frame 6200 can be combined, and the filter device 6000 can be positioned at the opening 2100.

[0109] Furthermore, if Fig.16 As shown, in some embodiments, the outer wall 6211 of the mounting frame 6200 is higher than the inner wall 6213 of the mounting frame 6200, which is not only conducive to the fixation of the bottom of the filter 6100, but also allows the entire mounting frame 6200 to be embedded in the fuselage 1000, that is, most of the filter device 6000 is embedded in the fuselage 1000, thereby compressing the thickness of the combination stove, so that the combination stove can be made thinner.

[0110] Specifically, the bottom of the filter 6100 is supported on the inner wall 6213 of the mounting frame 6200 and abuts against the outer wall 6211 of the mounting frame 6200, thereby achieving the fixation of the bottom of the filter 6100. Moreover, this fixing method enables the bottom of the filter 6100 to be above the bottom of the liquid collecting tank 6210 and not in contact with the bottom of the liquid collecting tank 6210, so that the condensed water on the filter 6100 can be easily dripped into the liquid collecting tank 6210. By designing the outer wall 6211 to be higher, most of the structure of the mounting frame 6200 can be embedded in the fuselage 1000, thereby reducing the thickness of the combined stove and facilitating the installation of other components.

[0111] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
