Description

Technical Field

[0001] This invention relates to a household appliance, particularly a wine cabinet, tea cabinet, or cigar cabinet. Background Technology

[0002] In existing technologies, the refrigeration system of a typical storage cabinet includes a fan, a humidifier, and an evaporator. The fan blows air from inside the cabinet over the humidifier to increase the humidity, and then blows the humidified air over the evaporator to cool it down. The cooled air is then blown back into the cabinet through the air outlet, thus forming a circulation. However, common humidifiers include a water tank with a water curtain that comes into contact with water. The fan blows air onto the water curtain, using water evaporation to humidify the air. This type of water curtain humidifies by absorbing water and then evaporating it upon contact with the air. Its humidification capacity depends on the moisture level of the water curtain. On the one hand, its humidification effect is unstable; on the other hand, after a period of use, the water absorption and evaporation efficiency of the water curtain will significantly decrease, which will lead to a decrease in the humidification effect of the refrigeration system. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a humidifying wheel, a humidifying mechanism and a household appliance.

[0004] The technical solution adopted by this invention to solve its technical problem is: A humidifying wheel includes fan blades that rotate by wind power. The outer side of the fan blades is integrally formed with a water-contacting part, and the water-contacting part is provided with a plurality of through holes for forming a water film after contacting water.

[0005] As a further improvement of the present invention, the front and rear sides of the water-contacting part are provided with a number of U-shaped protrusions arranged circumferentially at intervals near the edge.

[0006] A humidification mechanism includes a water tank, in which at least one of the aforementioned humidification wheels is installed. After assembly, the lower part of the water-contacting part contacts the water in the water tank, and a humidifying fan is installed at the air inlet end of the water tank to blow air toward the surface of the humidification wheel.

[0007] Compared with the prior art, this application utilizes wind power to drive the humidifying wheel. During the rotation of the humidifying wheel, the through holes in the water-contacting part are submerged in water and then leave the water surface. Due to the surface tension of the water, a water film is formed on the through holes. The wind blows across the water film, thereby producing a humidifying effect, which can achieve uniform evaporation and stable humidification.

[0008] As a further improvement of the present invention, a rotating shaft is installed in the middle of the inner side of the fan blade, and the rotating shaft is rotatably connected to the water tank through a bearing.

[0009] As a further improvement of the present invention, a drain pipe connector and a water filling pipe connector are installed on the front side of the water tank near the bottom.

[0010] As a further improvement of the present invention, the humidification mechanism is also provided with an electric drive device, which includes a motor. The motor is installed on the rear side of the water tank, and after assembly, the output shaft of the motor is fixedly connected to the fan blade.

[0011] A household appliance includes a cabinet, wherein the humidification mechanism is installed inside the cabinet.

[0012] As a further improvement of the present invention, an air duct plate is installed on the rear side of the cabinet body, the air duct plate divides the cabinet body into a storage cavity and an air conditioning cavity, an evaporator is installed in the air conditioning cavity, a humidification cavity is provided at the bottom of the storage cavity, and the humidification mechanism is installed in the humidification cavity.

[0013] As a further improvement of the present invention, the lower side of the air conditioning cavity is provided with a first air inlet and a first circulating fan is installed at the opening of the first air inlet, and the upper side is provided with a plurality of air outlets arranged at intervals. The top of the humidification cavity is provided with a humidification air outlet at the end near the first air inlet.

[0014] As a further improvement of the present invention, a partition plate is installed inside the air conditioning cavity, which divides the air conditioning cavity into an air duct cavity and a cooling cavity. The first circulating fan is installed at the bottom of the air duct cavity, and the evaporator is installed inside the cooling cavity. A circulating air inlet is provided on the upper side of the partition plate, and a circulating air outlet is provided on the lower side, with a second circulating fan installed at the opening of the circulating air outlet.

[0015] The beneficial effects of this invention are as follows: A humidification mechanism is installed inside the cabinet. The humidification mechanism includes a water tank, and a humidification wheel is installed inside the water tank. The humidification wheel includes fan blades that rotate by wind power and a water-contacting part that contacts the water. A humidifying fan is installed at the air inlet of the water tank to blow air onto the surface of the humidification wheel. The wind power generated by the humidifying fan drives the humidification wheel to rotate as a whole. The lower part of the water-contacting part is immersed in the water in the water tank. Because the water-contacting part has through holes, when the through holes are removed from the water surface during rotation, water adheres to the through holes due to the surface tension of the water, forming a water film on the through holes. After the humidifying fan blows over the water film, the water evaporates, thereby achieving the purpose of humidification. This allows for uniform evaporation and stable humidification, thus improving the humidification effect. Attached Figure Description

[0029] Example 1: Refer to Figures 1 to 4 A humidifying wheel 1 includes a fan blade 12 that rotates by wind power. The outer side of the fan blade 12 is integrally formed with a water-contacting part 13. The water-contacting part 13 is provided with a plurality of through holes 14 for forming a water film after contacting water.

[0030] A humidification mechanism includes a water tank 2, in which at least one humidifying wheel is installed. After assembly, the lower part of the water-contacting part 13 contacts the water in the water tank 2. A humidifying fan 21 is installed at the air inlet of the water tank 2 to blow air onto the surface of the humidifying wheel 1. In this embodiment, the humidifying wheel 1 rotates as a whole by the wind force generated by the humidifying fan 21. The lower part of the water-contacting part 13 is immersed in the water in the water tank 2. Since the water-contacting part 13 is provided with through holes 14, during rotation, water adheres to the through holes 14 of the water-contacting part 13 by the surface tension of the water, forming a water film. After the humidifying fan 21 blows over the water film, the water evaporates, thereby achieving the purpose of humidification. It can achieve uniform evaporation, stable humidification, and improve the humidification effect.

[0031] The front and rear sides of the water-contacting part 13 are provided with several U-shaped protrusions 15 arranged circumferentially at intervals. In this embodiment, when the water level of the water tank 2 is not full, the through hole 14 on the center side of the humidifying wheel 1 cannot be immersed in water, resulting in a decrease in humidification. At this time, the U-shaped protrusions 15 will rotate along the humidifying wheel 1, bringing up some water, and flowing out after reaching the highest point, thereby wetting the entire humidifying wheel 1 and achieving the effect of increasing humidification.

[0032] A rotating shaft 22 is installed in the middle of the inner side of the fan blade 12. The rotating shaft 22 is connected to the water tank 2 through a bearing, so that the humidifying wheel 1 can run more smoothly and steadily under the action of wind.

[0033] The front side of the water tank 2 is equipped with a drain pipe connector 231 and a water filling pipe connector 241 near the bottom. Users can replace the water in the water tank 2 or increase the water volume according to the drain pipe connector 231 and the water filling pipe connector 241 to avoid hardening or mold growth caused by long-term use of the water and to ensure the cleanliness of the water in the water tank.

[0034] Reference Figures 3 to 10 A household appliance includes a cabinet 3, in which the humidification mechanism is installed. Specifically, an air duct plate 4 is installed on the rear side of the cabinet 3, which divides the cabinet 3 into a storage cavity 31 and an air conditioning cavity 41. An evaporator 5 is installed in the air conditioning cavity 41. The humidified air comes into contact with the surface of the evaporator 5. The cool air that is blown over the evaporator 5 to complete the cooling and dehumidification is then mixed with part of the original air in the storage cavity 31. After mixing, the air is blown into the storage cavity 31 from the exhaust port 44 to achieve constant temperature and humidity regulation.

[0035] The humidification mechanism can be installed inside the air conditioning chamber 41, or it can be installed separately. Figure 3 and Figure 4 In the first embodiment of the standalone installation method, a humidification chamber 32 is provided at the bottom of the storage cavity 31, and the humidification mechanism is installed inside the humidification chamber 32. A first air inlet 42 is provided on the lower side of the air conditioning cavity 41, and a first circulating fan 43 is installed at the opening of the first air inlet 42. Several exhaust vents 44 are arranged at intervals on the upper side. A humidification outlet 33 is provided at the top of the humidification chamber 32 near the first air inlet 42. In this embodiment, part of the air in the storage cavity 31 enters the air conditioning cavity 41 from the first air inlet 42, and another part enters the humidification mechanism from the humidification chamber 32. After the humidification mechanism humidifies the air, it is blown out from the humidification outlet 33. Since the humidification outlet 33 is close to the first air inlet 42, after the first circulating fan 43 is started, it will draw the humidified air into the air conditioning cavity 41. This embodiment separates the humidification part and the air mixing part to avoid mutual interference between temperature and humidity regulation.

[0036] A partition plate 45 is installed inside the air conditioning cavity 41, dividing the air conditioning cavity 41 into an air duct cavity and a cooling cavity 46. The first circulating fan 43 is installed at the bottom of the air duct cavity, and the evaporator 5 is installed inside the cooling cavity 46. A cooling air inlet 47 is provided on the upper side of the partition plate 45, and a cooling air outlet is provided on the lower side. A second circulating fan 48 is installed at the opening of the cooling air outlet. In this embodiment, after the humidified air enters the air conditioning cavity 41, it flows upward through the first circulating fan 43. The air in the air duct cavity is blown upward by the second circulating fan 48. Part of the air in the air duct cavity is blown out from the multiple exhaust ports 44, and another part enters the cooling cavity 46 from the cooling air inlet 47. The air blown into the cooling cavity 46 passes over the evaporator 5 for cooling and dehumidification, and then is blown back into the air conditioning cavity 41 from the first air circulating fan 48, forming a complete air circulation.

[0037] Reference Figure 5 and Figure 6 , Figure 5 and Figure 6 This is a schematic diagram of the second embodiment of the humidification mechanism. At least one humidifying wheel 1 is installed in the water tank 2. In this embodiment, two humidifying wheels 1 are installed. Specifically, two humidifying wheels 1 are installed on the left and right sides of the water tank 2 respectively. Two humidifying fans 21 are also provided in the humidification chamber 32 corresponding to the humidifying wheels 1. By increasing the number of humidifying wheels 1 and humidifying fans 21, the humidification effect is improved.

[0038] Reference Figure 7 and Figure 8 , Figure 7 and Figure 8 This is a schematic diagram of the third embodiment. The humidifying mechanism is installed inside the air conditioning cavity 41. Specifically, the humidifying mechanism is fixedly installed at the bottom of the air conditioning cavity 41. Second air inlets 34 are respectively provided on both sides of the air duct plate 4 near the humidifying fan 21. An intake fan 35 is installed on the side of the second air inlet 34 facing the air conditioning cavity 41. In this embodiment, the humidifying mechanism is installed inside the air conditioning cavity 41, so that the air conditioning structure is located on the rear side of the cabinet 3, which facilitates assembly. Moreover, intake fans 35 are respectively provided on both sides of the humidifying mechanism to increase the air intake volume, which greatly increases the total airflow in the air conditioning cavity. Sufficient airflow can push the mixed air to flow more quickly across the surface of the evaporator 5, ensuring more sufficient heat exchange between the air and the evaporator, thereby improving the conditioning efficiency.

[0039] The humidification mechanism is also equipped with an electric drive device, as shown in the reference. Figure 9 and Figure 10 , Figure 9 and Figure 10 The humidification mechanisms are all driven by electric motors. Figure 9The humidification mechanism is installed inside the humidification chamber 32. Figure 10 The humidification mechanism is installed inside the air conditioning chamber 41. In this embodiment, the electric drive device includes a motor 7, which is fixedly installed on the rear side of the water tank 2 by screws. The water tank 2 is provided with a through hole through which the output shaft of the motor 7 passes. After assembly, the output shaft of the motor 7 is inserted into the shaft hole 121 of the fan blade 12, and the humidification wheel 1 is driven to rotate by the motor 7. Compared with the humidification wheel 1 driven by wind power, the motor drive is more stable. When the wind power is insufficient, the electric drive device starts to provide power. However, since the motor is often in a humid environment, its service life is not long. Therefore, it is better to use a motorless structure, which not only simplifies the assembly structure but also improves the service life.

[0040] Example 6: Refer to Figure 11 and Figure 12 A humidifying wheel 1 includes a fan blade 12 that rotates by wind power. The outer side of the fan blade 12 is integrally formed with a water-contacting part 13. The water-contacting part 13 is provided with a plurality of through holes 14 for forming a water film after contacting water.

[0041] A humidification mechanism includes a water tank 2, in which at least one of the aforementioned humidification wheels is installed. After assembly, the lower part of the water-contacting part 13 and the water-contacting plate 16 are in contact with the water in the water tank 2. A humidification fan 21 is installed at the air inlet end of the water tank 2 to blow air toward the surface of the humidification wheel 1.

[0042] In this embodiment, a water-contact plate 16 adapted to the shape of the water-contact part 13 is installed on one side of the water-contact part 13. An insertion interface 131 is provided on one side of the water-contact part 13. The water-contact plate 16 is provided with a plug post 161 corresponding to the insertion interface 131. After assembly, the plug post 161 is inserted into the insertion interface 131. The assembly structure is simple. Moreover, the water-contact plate 16 is also provided with several circumferentially spaced through holes 14, so that when the humidifying wheel 1 rotates, the surfaces of the water-contact plate 16 and the water-contact part 13 simultaneously form a water film, which has a multi-layer water film structure and further improves the humidification effect.

[0043] The front and rear sides of the water-contact plate 16 are provided with several U-shaped protrusions 15 arranged circumferentially. When the water level in the water tank 2 is not full, the through hole 14 on the central side of the humidifying wheel 1 cannot be immersed in water, resulting in a decrease in humidification. At this time, the U-shaped protrusions 15 will rotate along the humidifying wheel 1, carrying some water up and flowing out after reaching the highest point, thereby wetting the entire humidifying wheel 1 and achieving the effect of increasing humidification.

[0044] In this embodiment, a drain pump 23 and a fill pump 24 are installed in the water tank 2. Specifically, the drain pump 23 and the fill pump 24 are fixedly connected to the water tank 2 by screws. One end of the water pipe of the drain pump 23 is in contact with the water in the water tank 2, and the other end extends from the drain pipe connector 231 on the front side of the water tank 2. One end of the water pipe of the fill pump 24 is in contact with the water in the water tank 2, and the other end extends from the fill pipe connector 241 on the front side of the water tank 2. Users can replace the water in the water tank 2 or increase the water volume according to the drain pipe connector 231 and the fill pipe connector 241 to avoid hardening or mold growth caused by long-term use of the water and to ensure the cleanliness of the water in the water tank.

[0045] The above embodiments do not limit the scope of protection of this invention. All equivalent modifications and variations made by those skilled in the art without departing from the overall concept of this invention are still within the scope of this invention.
