TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to an air outlet device and a household appliance. BACKGROUND

[0002] With the improvement of people's living standards, air heaters, warm air fans, electric fans and other air outlet household appliances have entered people's daily life. However, the air outlet direction of the existing air outlet household appliances is single, limited to front air outlet or upper air outlet, and the air supply range is limited, which cannot meet the use demand of users. SUMMARY

[0003] Therefore, the present application provides an air outlet device to solve the problem of single air outlet direction and limited air supply range of the air outlet device in the prior art.

[0004] The present application provides an air outlet device, comprising:

[0005] a shell, the shell being provided with an air inlet and at least two air outlets, the at least two air outlets being arranged to blow air in different directions;

[0006] an airflow adjusting device arranged in the shell, the airflow adjusting device being capable of generating airflow and delivering the airflow to the at least two air outlets respectively.

[0007] Beneficial effects: the at least two air outlets arranged on the shell can blow air in different directions, expand the air supply range of the air outlet device, make the whole room quickly warm up or cool down, meet the use demand of users to quickly reach the set temperature, and solve the problems of single air outlet direction, limited air supply range and poor use experience of the air outlet device in the prior art.

[0008] In an optional embodiment, the air outlet comprises:

[0009] a first air outlet arranged at the bottom of the side wall of the shell, a first air duct being formed in the shell and communicating the airflow outlet of the airflow adjusting device with the first air outlet;

[0010] a second air outlet arranged at the top wall of the shell, a second air duct being formed in the shell and communicating the airflow outlet of the airflow adjusting device with the second air outlet.

[0011] Beneficial effects: the first air outlet is arranged at the bottom of the side wall of the shell, and the second air outlet is arranged at the top wall of the shell, which can realize the effect of blowing air from the top and the side at the same time, expand the air supply range of the air outlet device, realize the diffusion of larger air volume, and improve the comfort of indoor environment.

[0012] In an optional embodiment, the air outlet device further comprises:

[0013] The splitting structure is provided at the air flow outlet and is used to split the air flowing out of the air flow outlet into two air flows which are respectively connected to the first air duct and the second air duct.

[0014] Beneficial effect: By setting up a diversion structure, the airflow led out from the wind wheel outlet can be diverted into two airflows connected to the first air outlet and the second air outlet respectively, thereby achieving the effect of simultaneous air outlet from both sides with almost no loss of air volume, thereby expanding the air supply range and improving the comfort of the indoor environment.

[0015] In an optional embodiment, the wind coming out of the air outlet is hot air, and the heat of the air flow flowing to the first air outlet after being divided by the diversion structure is set to Q1, and the heat of the air flow flowing to the second air outlet is set to Q2, where 1 / 5<Q2:Q1<1 / 3.

[0016] Beneficial effect: The diversion structure can divide the hot air coming out of the airflow outlet into two directions: horizontal forward and vertical upward. By controlling the heat Q1 of the airflow flowing to the first air outlet and the heat Q2 of the airflow flowing to the second air outlet within the ratio range of 1 / 5<Q2:Q1<1 / 3, a small part of the heat flows out upward through the second air outlet, avoiding a large amount of hot air directly blowing onto the user's face, which causes a poor user experience and improves user comfort. Most of the heat flows forward through the first air outlet, and the hot air flow going out from the front realizes axial air supply to heat the bottom and slowly supplies heat upward through natural convection, realizing carpet-style heat supply, three-dimensional wrapping air supply, and whole-house heating. It greatly improves the comfort of the indoor environment and can meet the user's needs for heating both the feet and the body at the same time.

[0017] In an optional embodiment, the cross-sectional area of ​​the air flow outlet is set to S1, and the cross-sectional area of ​​the inlet of the second air duct is set to S2, wherein 1 / 6<S2:S1<1 / 4.

[0018] Beneficial effect: By setting the cross-sectional area S1 of the air outlet and the cross-sectional area S2 of the inlet of the second air duct within the ratio range of 1 / 6<S2:S1<1 / 4, it can effectively ensure that most of the airflow coming out of the air outlet flows forward through the first air outlet, and a small part flows upward through the second air outlet, so that the heat distribution ratio is more reasonable, avoiding the problem of a large amount of hot air blowing directly on the face of the person. The first air outlet at the bottom of the side transfers heat in the horizontal direction and slowly sends heat upward through natural convection, and will not blow directly on the face of the person. Most of the heat is transported forward, changing the direction of heat flow, which can achieve the effect of three-dimensional heating of the whole house and higher comfort.

[0019] In an optional embodiment, the air outlet area of ​​the second air outlet is larger than the air outlet area of ​​the first air outlet.

[0020] Beneficial effect: By setting the outlet area of ​​the second air outlet on the top to be larger than the outlet area of ​​the first air outlet at the bottom, the heat at the top can be discharged through a larger air outlet area, thereby reducing the amount of heat discharged per unit area on the top, and the temperature of the upper surface of the entire shell is low and relatively uniform, so that the upper surface is not hot to the touch. The first air outlet at the bottom transfers heat in a horizontal direction and is a surface that is not in direct contact with the human body, so there is no problem of being hot to the touch. The heat coming out of the first air outlet is relatively high and is transported forward, changing the direction of heat flow, thereby achieving a three-dimensional heating effect for the entire house.

[0021] In an optional embodiment, the area of ​​the first air outlet is S3, and the area of ​​the second air outlet is S4, wherein 1.0<S4:S3<1.2.

[0022] Beneficial effect: By setting the area S3 of the first air outlet and the area S4 of the second air outlet within the above-mentioned proportional range, the problem of the air outlet area of ​​the second air outlet being too large, thereby affecting the heating effect, can be effectively avoided.

[0023] In an optional embodiment, the housing includes:

[0024] Shell body;

[0025] A first air outlet grille is provided on a side of the housing body close to the air flow outlet, and a grille gap of the first air outlet grille constitutes a first air outlet;

[0026] The diversion structure is fixed to the first air outlet grille.

[0027] Beneficial effect: By fixing the diversion structure and the first air outlet grille together, the step of separately disassembling and assembling the diversion structure can be omitted, the assembly efficiency is higher, and the subsequent disassembly and maintenance is more convenient.

[0028] In an optional embodiment, the first air outlet grille includes one or more grille bars, and the diversion structure is a diversion plate, which is formed by extending the grille bars in a direction close to the airflow adjustment device.

[0029] Beneficial effect: The diverter plate is arranged horizontally at the air flow outlet. The diverter plate is a plate-like structure formed by the grille bars of the first air outlet grille protruding and extending inward, thereby achieving the effect of dividing the air flow drawn out from the air flow outlet into two air flows, the front and the upper air flows.

[0030] In an optional embodiment, the shell body includes a front plate and a rear plate that are arranged opposite to each other, and the first air outlet grille is located below the front plate;

[0031] A plane coplanar with the rear plate is defined as a reference plane, and a distance between the first air outlet grille and the reference plane is smaller than a distance between the front plate and the reference plane.

[0032] Beneficial effects: through the above design, the first air outlet grille provided with the first air outlet is arranged in a recessed manner compared to the front plate, so that the hidden arrangement of the first air outlet at the bottom can be realized, the hidden air outlet of the air outlet device is realized, and the aesthetic degree of the air outlet household appliance is improved.

[0033] In a second aspect, the present application also provides a household appliance comprising the air outlet device described in the above embodiments.

[0034] In an alternative embodiment, the airflow adjusting device comprises a fan wheel assembly, which comprises:

[0035] The fan wheel and the volute tongue and volute shell arranged at the outer circumferential side of the fan wheel in a circumferential interval of the fan wheel, and the intervals on both sides of the volute tongue and volute shell respectively form the airflow inlet and the airflow outlet.

[0036] Beneficial effects: the airflow adjusting device uses the fan wheel as the airflow driving member, the air outlet is continuous and soft, and the intervals on both sides of the volute tongue and volute shell form the airflow inlet and the airflow outlet without the need for separate openings, which simplifies the molding process and is more convenient for demolding.

[0037] In an alternative embodiment, the airflow adjusting device further comprises:

[0038] The heating component is arranged in the shell and located at the air inlet side of the fan wheel, and the projection of the heating component and the fan wheel along the height direction of the shell at least partially overlaps.

[0039] Beneficial effects: the heating component is arranged at the air inlet side of the fan wheel assembly, and the projection of the heating component and the fan wheel along the height direction of the shell at least partially overlaps, so as to effectively ensure the compactness of the air outlet device in the transverse direction, i.e. the width is not too large, improve the compactness of the structure of the air outlet device, and facilitate the miniaturization design of the air outlet household appliance and reduce the floor area.

[0095] The embodiments of the present application will be described below in conjunction with Figures 1 to 23 .

[0096] According to the embodiments of the present application, the present application provides an air outlet device, comprising a shell 10 and an airflow adjusting device 20, the shell 10 is provided with an air inlet 130 and at least two air outlets, the at least two air outlets are arranged to blow air in different directions; the airflow adjusting device 20 is arranged in the shell 10, and the airflow adjusting device 20 can generate airflow and deliver the airflow to the at least two air outlets respectively.

[0097] In the above embodiments, by arranging at least two air outlets on the shell 10, air can be blown in different directions, the air supply range of the air outlet device is expanded, the whole room can be quickly heated or cooled, the use demand of the user to quickly reach the set temperature is met, and the problem of single air outlet direction, limited air supply range and poor use experience of the air outlet device in the prior art is solved.

[0098] In the present embodiment, the air outlet device is applied to air outlet household appliances, including but not limited to a warmer, a fan heater and an electric fan. Preferably, the air outlet device in the present embodiment is applied to a warmer, and more preferably, the air outlet device is applied to a skirting warmer.

[0099] In some embodiments, as shown in Figures 1 to 4 , Figure 10 , the air outlet comprises a first air outlet 101 and a second air outlet 102, the first air outlet 101 is arranged at the bottom of the side wall of the shell 10, a first air duct is formed in the shell 10, the first air duct is communicated with the airflow outlet 202 of the airflow adjusting device 20 and the first air outlet 101; the second air outlet 102 is arranged on the top wall of the shell 10, a second air duct is formed in the shell 10, the second air duct is communicated with the airflow outlet 202 of the airflow adjusting device 20 and the second air outlet 102.

[0100] In the above embodiment, the first air outlet 101 is arranged at the bottom of the side wall of the shell 10, and the second air outlet 102 is arranged at the top wall of the shell 10, so that the air can be blown out from the top and the side at the same time, the air supply range of the air supply device is expanded, and the air is diffused in a larger range, thereby improving the comfort of the indoor environment.

[0101] Preferably, the air flow adjusting device 20 is applied to a warmer, the air blown out from the air flow outlet 202 is hot air, the hot air blown out from the first air outlet 101 on the side realizes axial air supply to heat the bottom and slowly supply heat upward by natural convection, and the hot air blown out from the second air outlet 102 on the top can enhance the upward heat transfer rate, thereby improving the overall heat and expanding the heat dissipation range of the air supply device, so that the heat is diffused in a larger range, the demand of the user for heating the feet and the body at the same time is met, the comfort of the indoor environment is improved, and the demand of heating the whole house is met.

[0102] Specifically, the first air outlet 101 is arranged on the front side wall of the shell 10, and the shell body includes a bottom plate 14, a front plate 11, a rear plate 13 and left and right side plates. The first air outlet 101 is arranged on the front side wall of the shell 10, and the shell body includes a bottom plate 14, a front plate 11, a rear plate 13 and left and right side plates. The bottom of the front plate 11 is provided with a first air outlet grille 111, and the rear plate 13 is provided with an air inlet 130. The air inlet 130 is in communication with the outside space, and is used to introduce the outside air into the shell 10 for heating, and then convey the air to the fan assembly.

[0103] Further, the air flow outlet 202 is located at the bottom of the shell 10, and the air flow outlet 202 faces the first air outlet 101. The projection of the first air outlet 101 in the vertical direction falls into the air flow outlet 202. The second air outlet 102 is arranged on one side of the top wall of the shell 10 close to the first air outlet 101.

[0104] It should be noted that in the present embodiment, the first air outlet 101 and the second air outlet 102 can also be arranged on the opposite two side walls of the shell 10, and the number of air outlets is not limited to two, but can also be three, four or more.

[0105] In some embodiments, the air supply device further comprises a flow dividing structure 100 arranged at the air flow outlet 202, for dividing the air blown out from the air flow outlet 202 into two air flows communicated with the first air duct and the second air duct respectively.

[0106] In the above embodiment, the flow dividing structure 100 is arranged, so that the air flow blown out from the air flow outlet 202 can be divided into two air flows communicated with the first air outlet 101 and the second air outlet 102 respectively, and the air can be blown out from the two sides at the same time under the condition that the air volume is almost not lost, so that the air supply range is expanded, and the comfort of the indoor environment is improved.

[0107] Specifically, the flow splitting structure 100 can be a flow splitting rib or a flow splitting plate. The flow splitting structure 100 is detachably connected to the shell 10 or integrally formed with the shell 10.

[0108] Preferably, the flow splitting structure 100 is integrally formed with the shell 10. The flow splitting structure 100 is integrally formed with the shell 10, which can make the airflow more stable and reduce the vortex effect, thereby significantly reducing the whistling sound and noise, improving the user experience, and avoiding the problem that the assembly of the flow splitting structure 100 and the shell 10 causes the vortex effect in the air duct to be intensified, resulting in a larger noise.

[0109] In some embodiments, the heat of the airflow flowing to the first air outlet 101 after being split by the flow splitting structure 100 is set as Q1, and the heat of the airflow flowing to the second air outlet 102 is set as Q2, where 1 / 5 < Q2:Q1 < 1 / 3.

[0110] In the above embodiments, the flow splitting structure 100 can split the hot air from the airflow outlet 202 into two directions, i.e., horizontally forward and vertically upward. By controlling the heat Q1 of the airflow flowing to the first air outlet 101 and the heat Q2 of the airflow flowing to the second air outlet 102 within the range of 1 / 5 < Q2:Q1 < 1 / 3, a small part of the heat is allowed to flow upward through the second air outlet 102, avoiding the problem that a large amount of hot air directly blows on the user's face, improving the user experience, and improving the user comfort. A large part of the heat flows forward through the first air outlet 101, and the hot airflow flowing forward realizes axial air supply to heat the bottom and slowly send heat upward through natural convection, realizing carpet-type heat supply and three-dimensional wrapping air supply, which greatly improves the comfort of the indoor environment and meets the user's demand for heating the feet and the body at the same time.

[0111] Preferably, Q2:Q1 = 1 / 4, i.e., the ratio of the upward heat to the forward heat is about 1:4, which means that the vertical upward heat accounts for 20%, and the horizontal forward heat accounts for about 80%.

[0112] In some embodiments, the cross-sectional area of the airflow outlet 202 is set as S1, and the cross-sectional area of the inlet of the second air duct is set as S2, where 1 / 6 < S2:S1 < 1 / 4.

[0113] In the above embodiments, by setting the cross-sectional area S1 of the air outlet 202 and the cross-sectional area S2 of the inlet of the second air duct in the ratio range of 1 / 6

[0114] Preferably, S2:S1 = 1 / 5, that is, the ratio of the cross-sectional area of the inlet of the second air duct to the cross-sectional area of the air outlet 202 is about 1:5. By setting S1 and S2 in the above ratio range, the upward and forward heat division ratio can be effectively ensured to be about 1:4, so that the heat distribution ratio is more reasonable.

[0115] In some embodiments, in combination with Figure 4 and Figure 5 As shown, the length of the air outlet 202 is L1 and the width is W1, and the length of the inlet of the second air duct is L2 and the width is W2, wherein L1 = L2, 1 / 6

[0116] In a specific example, the size of the air outlet 202 is 474.8 mm in length and 25.9 mm in width, and the size of the inlet of the second air duct is 474.8 mm in length and 5 mm in width. The air from the air outlet 202 flows in the horizontal and vertical directions after being divided by the flow dividing structure 100, wherein about 20% of the heat is transmitted vertically upward to the second air outlet 102 through the inlet of the second air duct, and the remaining 80% of the heat is transmitted horizontally to the first air outlet 101.

[0117] In some embodiments, the air outlet area of the second air outlet 102 is greater than the air outlet area of the first air outlet 101.

[0118] In the above embodiments, by setting the air outlet area of the top second air outlet 102 to be greater than the air outlet area of the bottom first air outlet 101, the heat at the top can be made to flow out through a larger air outlet area, thereby reducing the heat per unit area at the top, and the temperature of the upper surface of the entire shell 10 is relatively low and uniform, thereby achieving the effect of not being scalding hot on the upper surface. The first air outlet 101 at the bottom is for horizontal heat transfer, and the surface not in direct contact with the human body does not have the problem of being scalding hot, while the heat from the first air outlet 101 is relatively high and is transported forward, changing the direction of heat flow, achieving the effect of three-dimensional temperature rise in the whole house.

[0119] In some embodiments, the area of the first air outlet 101 is S3, and the area of the second air outlet 102 is S4, wherein 1.0 < S4:S3 < 1.2.

[0120] In the above embodiments, by setting the area S3 of the first air outlet 101 and the area S4 of the second air outlet 102 within the above ratio range, the problem of the air outlet area of the second air outlet 102 being too large and affecting the heating effect can be effectively avoided.

[0121] Preferably, S4:S3 is 1.1:1.0.

[0122] In some embodiments, the shell 10 includes a shell body and a first air outlet grille 111, the first air outlet grille 111 is arranged on one side of the shell body close to the air outlet 202, the grille gap of the first air outlet grille 111 constitutes the first air outlet 101; the flow splitting structure 100 is fixedly arranged on the first air outlet grille 111.

[0123] In the above embodiments, by fixing the flow splitting structure 100 and the first air outlet grille 111 integrally, the step of disassembling the flow splitting structure 100 separately can be omitted, the assembly efficiency is higher, and the disassembly and maintenance in the later stage are more convenient.

[0124] Preferably, the flow splitting structure 100 and the first air outlet grille 111 are integrally formed, which is more convenient for processing, forming, disassembly and maintenance than the flow splitting structure 100 and the shell body being integrally formed.

[0125] In some embodiments, the first air outlet grille 111 includes one or more grille bars, and the flow splitting structure 100 is a flow splitting plate, which is formed by the grille bars extending towards the air flow adjusting device 20. The flow splitting plate is arranged transversely at the air outlet 202, and the flow splitting plate is a plate structure formed by the grille bars of the first air outlet grille 111 extending inwardly, so as to achieve the effect of splitting the air flow drawn from the air outlet 202 into front and upper air flows.

[0126] Specifically, the first air outlet grille 111 is detachably mounted on the shell body, which is convenient for cleaning and maintenance. The bottom position of the front plate 11 of the shell body is provided with a mounting opening, and the first air outlet grille 111 is detachably mounted at the mounting opening of the shell body. Optionally, the first air outlet grille 111 is mounted and fixed on the shell body by means of screws, buckles 122, interference fit, etc. The first air outlet grille 111 is integrally injection molded with the flow splitting structure 100. Of course, in alternative embodiments, the flow splitting structure 100 can also be integrally formed with the front plate 11 of the shell body.

[0127] In some preferred embodiments, the first air outlet grille 111 comprises a plurality of grille bars arranged in an up-down direction, and the flow distribution plate is formed by extending the topmost grille bar towards the air flow adjusting device 20; the lowest point of the flow distribution plate is higher than the highest edge of the air outlet 202.

[0128] In the above embodiments, the design of extending the topmost grille bar to form the flow distribution plate makes the first air outlet 101 located below the flow distribution plate as a whole, so that all the air below the flow distribution plate flows to the first air outlet 101 after being distributed by the flow distribution plate, and all the air above the flow distribution plate flows to the second air outlet 102, thereby ensuring the distribution effect, reducing the air volume loss, avoiding the problem of air volume loss caused by the mixing of the distributed air, and achieving the purposes of improving the stability of the air flow and reducing the howling sound.

[0129] In some embodiments, the lowest point of the flow distribution plate is not lower than the highest edge of the air outlet 202. By setting the flow distribution plate to be higher than or equal to the highest edge of the air outlet 202 of the air flow adjusting device 20, compared with setting the flow distribution plate below the highest edge of the air outlet 202, the howling sound is smaller, which can effectively reduce the noise of the air outlet device during operation and provide a better user experience.

[0130] Preferably, the lowest point of the flow distribution plate is higher than the highest edge of the air outlet 202.

[0131] In some embodiments, the shell body comprises a front plate 11 and a rear plate 13 arranged oppositely, and the first air outlet grille 111 is located below the front plate 11; a plane coplanar with the rear plate 13 is defined as a reference plane, and the distance between the first air outlet grille 111 and the reference plane is smaller than the distance between the front plate 11 and the reference plane.

[0132] Through the above design, the first air outlet grille 111 provided with the first air outlet 101 is set to be recessed relative to the front plate 11, which can realize the hidden setting of the first air outlet 101 at the bottom and achieve the hidden air outlet of the air outlet device, thereby improving the aesthetic appearance of the air outlet household appliance.

[0133] In an alternative embodiment, the flow distribution structure 100 comprises a flow blocking part 1001, and the topmost grille bar of the first air outlet grille 111 is extended to form the flow blocking part 1001 which extends horizontally or extends upwardly or extends downwardly. Through the design of the flow blocking part 1001, the flow blocking part 1001 can block the air flow from the air outlet 202, thereby preventing the air flow from flowing to the second air outlet 102 and allowing part of the air flow to flow to the first air outlet 101, thereby achieving the effect of air outlet from the top and front surfaces at the same time.

[0134] In an alternative embodiment, the flow splitting structure 100 comprises a blocking portion 1001 and a supporting portion 1002, the topmost grid bar of the first air outlet grille 111 extends upwardly to form the supporting portion 1002 near the side edge of the airflow adjusting device 20, and the upper end of the supporting portion 1002 extends to form the blocking portion 1001 in the direction close to the airflow adjusting device 20. Through the design of the supporting portion 1002, the supporting portion 1002 can support the blocking portion 1001 at a certain height above the first air outlet 101, so that the blocking portion 1001 has a certain interval distance with the upper edge of the first air outlet 101, avoiding the blocking portion 1001 being close to the upper edge of the first air outlet 101 and affecting the air outlet.

[0135] In this embodiment, the blocking portion 1001 is arranged transversely at the airflow outlet 202, and preferably, the blocking portion 1001 is higher than the airflow outlet 202.

[0136] In some specific examples, the blocking portion 1001 is arranged horizontally and formed by the horizontal extension of the grid bar, the grid bar extends vertically upward to form the supporting portion 1002 near the side edge of the airflow adjusting device 20, and the upper end of the supporting portion 1002 extends horizontally to form the blocking portion 1001 in the direction close to the airflow adjusting device 20, the supporting portion 1002 is a vertical plate structure, the blocking portion 1001 is a horizontal plate structure, and the supporting portion 1002 and the blocking portion 1001 form an L-shaped plate structure. In other alternative embodiments, the blocking portion 1001 is arranged obliquely, the blocking portion 1001 gradually inclines upwardly from the first air outlet 101 to the airflow adjusting device 20, or the blocking portion 1001 gradually inclines downwardly from the first air outlet 101 to the airflow adjusting device 20.

[0137] Preferably, a reinforcing rib is arranged between the supporting portion 1002 and the topmost grid bar, and the reinforcing rib is a plurality of reinforcing ribs arranged at intervals along the length direction of the grid bar. The reinforcing rib can increase the stability of the flow blocking plate structure, thereby ensuring the stability of the airflow and reducing the howling sound.

[0138] In some embodiments, the shell 10 further comprises a second air outlet grille 12 arranged at the top of the shell body, and preferably, the second air outlet grille 12 constitutes the top wall of the shell 10, and part of the grid gaps of the second air outlet grille 12 constitutes the second air outlet 102.

[0139] Further, in combination with Figure 1 , Figure 6 and Figure 7As shown, the first air outlet grille 111 has a first air outlet area a, and the grille gap of the first air outlet area constitutes the first air outlet 101. The second air outlet grille 12 has a second air outlet area b, and the grille gap of the second air outlet area constitutes the second air outlet 102. The area ratio of the second air outlet area b to the first air outlet area a is about 1.1:1.0, that is, the top air outlet area is slightly larger than the bottom air outlet area. This design makes the heat blown out by the grille in two directions of upward and forward after being divided by the shunt structure 100. 20% of the heat at the top is blown out through a larger air outlet area, so that the heat per unit area is less, the temperature of the whole surface is lower and relatively uniform, and the effect of not being scalding hot on the top surface is achieved. The bottom is horizontal heat transfer, and the surface is not directly contacted by the human body. 80% of the heat is transported forward to change the heat flow direction and achieve the effect of three-dimensional temperature rise in the whole house.

[0140] In some embodiments, the air flow adjusting device 20 comprises a fan wheel assembly having an air flow inlet 201 and an air flow outlet 202, the fan wheel assembly comprising a fan wheel 21, and a volute tongue 22 and a volute shell 23 arranged at the outer circumferential side of the fan wheel 21 in a circumferential direction, and the space on both sides of the volute tongue 22 and the volute shell 23 constitutes the air flow inlet 201 and the air flow outlet 202 respectively. The air flow adjusting device 20 adopts the fan wheel 21 as the air flow driving member, so that the air outlet is continuous and soft, and the space on both sides of the volute tongue 22 and the volute shell 23 constitutes the air flow inlet 201 and the air flow outlet 202, so that separate openings are not needed, the molding process is simplified, and the mold is more convenient to remove.

[0141] Further, the volute tongue 22 comprises a volute tongue main body segment 221 and a volute tongue flow guide segment 222.

The volute tongue flow guide segment 222 is formed by extending from the air outlet end of the volute tongue main body segment 221 towards the second air outlet 102, for guiding the air flow to flow in the direction of the second air outlet 102. The shunt structure 100 and the volute tongue flow guide segment 222 have an air passing gap therebetween, which constitutes the inlet of the second air duct.

[0142] In the above embodiments, one side wall of the shunt structure 100 close to the volute tongue flow guide segment 222 and the volute tongue flow guide segment 222 and the outer shell form the second air duct. The cross-sectional area S2 of the inlet of the second air duct in the present application is the cross-sectional area of the air passing gap between the shunt structure 100 and the volute tongue flow guide segment 222. Through the design of the volute tongue flow guide segment 222, the volute tongue 22 can have the function of guiding the air flow, guiding the air flow in the upward branch to flow in the direction of the second air outlet 102, and achieving the effects of one thing serving multiple purposes and simplifying the structure.

[0143] Furthermore, the volute tongue main section 221 is located above the wind wheel 21, and the volute tongue guide section 222 is formed by vertically extending the air outlet end of the volute tongue main section 221. In other modified embodiments, the volute tongue guide section 222 is formed by obliquely extending the air outlet end of the volute tongue main section 221 upward. The volute tongue guide section 222 is inclined toward the direction close to the first air outlet 101 or can also be inclined toward the direction away from the first air outlet 101. The extension direction of the volute tongue guide section 222 is determined according to the relative position of the second air outlet 102 and the air outlet of the wind wheel 21.

[0144] In some embodiments, the projections of the diverter structure 100 and the volute tongue 22 in the housing width direction at least partially overlap. This design allows the diverter structure 100 to at least partially correspond to the volute tongue 22, thereby facilitating the diverter structure 100 and the volute tongue guide section 222 to cooperate to form the second air duct.

[0145] In some embodiments, as Figures 1 to 4 and Figure 10 As shown, the volute 23 includes a volute main section 231 and a volute guide section 232. The volute main section 231 is located below the wind wheel 21, and the volute guide section 232 is arranged at the air outlet end of the volute main section 231. The volute 23 guides the air and extends in the direction close to the first air outlet 101. The volute guide section 232 abuts against the inner wall of the first air outlet grille 111. The volute guide section 232 and the diversion structure 100 are surrounded by the side wall and outer shell of the volute guide section 232 to form a first air duct. The first air duct connects the air outlet of the wind wheel 21 and the first air outlet 101.

[0146] In the above embodiment, the volute 23 adopts the design of the volute guide section 232 so that the volute 23 can also have the function of guiding the air flow to guide the air flow of the front branch to flow in the direction of the first air outlet 101.

[0147] Furthermore, the volute main body section 231 and the volute guide section 232 are integrally formed, the volute main body section 231 is arc-shaped, and the wall surface of the volute guide section 232 facing the diversion structure 100 is a straight guide wall surface, which is used to guide the airflow drawn out from the air outlet of the wind wheel 21 to the first air outlet 101, and the wall surface of the volute guide section 232 facing the first air outlet grille 111 is fitted against the first air outlet grille 111 located below the lowest edge of the first air outlet 101, avoiding the formation of a gap between the volute 23 and the first air outlet grille 111 and causing air leakage. Through the above design, the volute guide section 232 can cooperate with the diversion structure 100 to form a relatively closed first air duct, thereby reducing air volume loss.

[0149] In the above embodiments, the heating component 24 is arranged at the air inlet side of the fan wheel assembly, and the projection of the heating component 24 and the fan wheel 21 along the height direction of the housing at least partially overlaps, so as to effectively ensure the compactness of the air outlet device in the transverse direction, i.e. the width is not too large, improve the compactness of the structure of the air outlet device, and is more conducive to the miniaturization design of the air outlet type household appliance and reduces the floor area.

[0150] Specifically, the heating component 24 is arranged above the fan wheel 21, and an air inlet channel is formed in the housing 10, the air inlet channel is communicated between the air inlet 130 of the housing 10 and the air inlet 201, and the heating component 24 is arranged in the air inlet channel and used for heating the air entering from the air inlet 130.

The large mist groups contact the second-level guide ribs 332 during the upward movement, and the second-level guide ribs 332 further divide the large mist groups into at least two small mist groups. The small mist groups rise along the second-level rising passages to the mist outlet 301. The two-level division and guiding make the mist more evenly distributed along the length direction of the mist outlet 301, and the mist is combed into smaller and more uniform mist groups, so that the mist output effect is good and the user experience is improved.

[0190] In some embodiments, the at least two first-level guide ribs 331 are arranged to be inclined to the direction of the mist inlet 3131.

[0191] The first-level guide ribs 331 are arranged to be inclined to the direction of the mist inlet 3131, so as to facilitate the upward movement trend of the longitudinally diffused mist, so as to guide the mist to change direction to the mist outlet 301 at the top.

[0192] In some embodiments, the lengths of the at least two first-level guide ribs 331 are different.

[0193] The interception of the mist needs to be different along the length direction of the diffusion passage, so the lengths of the at least two first-level guide ribs 331 are different to meet different mist interception requirements.

[0194] In some embodiments, the lengths of the at least two first-level guide ribs 331 gradually decrease from the position close to the mist inlet 3131 to the position far from the mist inlet 3131.

[0195] Since the mist close to the mist inlet 3131 needs to be intercepted with higher intensity, the mist amount can be more uniform in the entire longitudinal extension direction, so the length of the first-level guide rib 331 close to the mist inlet 3131 is set to be longer, which is beneficial to the uniform distribution of the mist.

[0196] In some embodiments, as shown in FIG. 6, the first-level guide ribs 331 are arranged to be inclined to the direction of the mist inlet 3131. Figure 11 and Figure 16As shown, the bottom surface of the reflux groove 313 is formed with a slope extending downwardly in the direction of the mist inlet 3131; and the slope includes a steep slope section 3133 located at the end of the reflux groove 313 away from the mist inlet 3131.

[0197] The mist guide structure further includes:

[0198] The flow guide long rib 333 is correspondingly arranged above the steep slope section 3133 in an oblique manner; and the length of the flow guide long rib 333 is greater than that of the adjacent primary flow guide rib 331.

[0199] The bottom surface of the reflux groove 313 is formed with a slope extending downwardly in the direction of the mist inlet 3131, which can make the collected condensed water reflux to the mist inlet 3131 by gravity, and then to the water tank of the atomization assembly 32 for recycling; the end of the reflux groove 313 away from the mist inlet 3131 is formed with a steep slope section 3133, i.e. a taper structure in the direction away from the mist inlet 3131, which can accelerate the flow of the mist and avoid the situation that the driving force is insufficient near the end portion to affect the mist emission; in order to adapt to the situation that the slope of the bottom surface of the reflux groove 313 is steeper at the end away from the mist inlet 3131, a flow guide long rib 333 with a length greater than that of the primary flow guide rib 331 is correspondingly arranged above the steep slope section 3133 in an oblique manner, which presses the mist downwardly to the steep slope section 3133 on the left side, increases the air pressure on the left side slope, plays a role in accelerating the flow of the mist, and makes the mist flow smoothly into the steep slope section 3133, so that the mist emission is more uniform.

[0200] In some embodiments, as shown in Figure 11 Each secondary flow guide rib 332 is arranged in a bent manner in the direction of the mist inlet 3131.

[0201] The secondary flow guide rib 332 for secondary guiding and shunting is arranged in a bent manner in the direction of the mist inlet 3131, which can further guide the mist after the change of direction of the primary flow guide rib 331, form the mist vertically upward, and discharge the mist along the secondary upward path through the mist outlet 301.

[0202] In some embodiments, as shown in Figure 11 and Figure 14 As shown, the lengths of all the secondary flow guide ribs 332 are equal.

[0203] After being guided by the primary flow guide rib 331, a large and uniform mist group has been formed, so the lengths of the secondary flow guide ribs 332 are equal, which can ensure the uniformity and consistency of the mist emission after the secondary guiding.

[0204] A plurality of first guide ribs 331 are arranged on the air guide cover 3111, and a plurality of second guide ribs 332 are arranged on the backflow groove 313. The upper end surface of the second guide ribs 332 is aligned with the lower end surface of the first guide ribs 331 of the edge of the first guide ribs 331, so that the mist entering from the mist inlet 3131 is divided by the plurality of layers and discharged from the mist outlet 120 at the upper end of the air guide cover 3111, and the mist is discharged more uniformly.

[0205] In some embodiments, as shown in FIGS. 18 and 19, the cross section of the backflow groove 313 is in the shape of a U. Figure 20

[0206] The backflow groove 313 in the shape of a U makes the condensed water flow easily along the two side walls to the bottom surface of the backflow groove 313, which is convenient for recycling.

[0207] In some embodiments, as shown in FIGS. 18 and 19, the bottom surface of the backflow groove 313 has a slope, and the bottom surface extends downwardly to the direction of the mist inlet 3131. Figure 11 Figure 22 The bottom surface of the backflow groove 313 forms a slope extending downwardly to the direction of the mist inlet 3131, so that the condensed water can flow back to the mist inlet 3131 by gravity, and then to the water tank of the atomization assembly 32 for reuse, which prevents the problem of water leakage on the ground and avoids the condensed water in the backflow groove 313 increasing the humidity in the mist outlet assembly 31 to cause the water vapor to enter the lampshade 3122 of the light emitting structure 312. Moreover, the condensed water flows back by gravity without the need for additional pumping devices, which reduces the number of components and improves reliability.

[0208] The bottom surface of the backflow groove 313 includes a steep slope section 3133 and a gentle slope section 3132. In some embodiments, the inclination angle of the gentle slope section 3132 can be selected as 0.5°, which reduces the dripping noise caused by the condensed water flowing back to the water tank of the atomization assembly 32. The inclination angle of the steep slope section 3133 is greater than that of the gentle slope section 3132.

[0209] In some embodiments, the air guide cover 3111 and the backflow groove 313 are detachably connected.

[0210] The air guide cover 3111 and the backflow groove 313 are detachably connected, which is convenient for maintenance and replacement of parts.

[0253] In some preferred embodiments, the household appliance is a warmer.

[0254] The specific structure and working principle of the warmer will be described below in combination with the drawings.

[0255] In this embodiment, the rear plate 13 of the shell 10 is provided with a plurality of small air inlet holes to form an air inlet 130. The heating component 24 is located on the air inlet side of the fan wheel 21. The upper air inlet cover plate 25 and the lower air inlet cover plate 26 are respectively located on the upper and lower sides of the heating component 24, covering the heating component 24, so as to ensure that the air sucked by the fan wheel 21 can effectively take away the heat of the heating component 24.
