Description

Technical Field

[0001] This application relates to the field of kitchen air purification equipment technology, and in particular to an air curtain structure that can achieve uniform airflow and an air conditioner having the air curtain structure. Background Technology

[0002] As we all know, the kitchen and cooking are indispensable parts of daily life in people's homes. With the improvement of people's living standards, people have increasingly higher requirements for the kitchen environment. Based on the existing functions and positioning of the kitchen, in addition to daily cleaning and cooking, the kitchen also serves as a garbage disposal area. Combined with the effects of cooking fumes and backflow of odors from the sewers, the inherent air environment in most kitchens is poor, with various odors and particulate matter mixed in, and even dust and bacteria particles. This not only seriously affects the cooking experience and the physical and mental health of the cook, but also sometimes poses a threat of contamination to the food and ingredients. Therefore, considering the special characteristics and functions of the kitchen environment, it is essential to equip the kitchen with air-purifying products.

[0003] Existing research and products address these issues. For example, Chinese utility model patent CN102252357A, entitled "Kitchen Oil Mist and Fume Purifier," discloses a kitchen oil mist and fume purifier that removes kitchen fumes through multiple purification methods. Another example is CN221259080U, which proposes an air conditioning technology using an air guide component and an ion generator to emit ions into the room, achieving air sterilization and purification.

[0004] However, the aforementioned research or design only involves installing ion generators and other devices with air-purifying functions on products or equipment. Existing technologies do not address how to rationally distribute the purifying ions generated by the ion generator within the purified space. Ion purification requires airflow guidance to achieve proper dispersion and effective distribution within the space to achieve better purification results and an improved overall user experience. Based on this issue, it seems necessary to implement overall space air purification by considering the characteristics of ion purification and airflow arrangement. Utility Model Content

[0005] This application provides an air curtain structure that can achieve uniform airflow and an air conditioner with such an air curtain structure, especially a range hood with air conditioning function. The structure or equipment of this solution can achieve uniform mixing of ions emitted by the ion generator with the airflow of the fan and uniform airflow of the ionized air, effectively improving the sterilization effect of the ion generator on the airflow, thereby better purifying the airflow and the ambient air in the space.

[0006] The air curtain structure that enables uniform airflow according to the embodiments of this application includes a fan assembly and an air outlet assembly. The fan assembly includes a purification motor and an impeller. An ion generating device is provided on the air outlet assembly. The ion generating device includes an ion emitting head. The impeller includes multiple sets of blades. The blades extend axially from the near end close to the ion emitting head to the far end away from the ion emitting head, and the blade tip diameter gradually decreases from the near end to the far end.

[0007] In a further alternative, the ion emitter is mounted at the middle of the impeller, with the two ends of the impeller being the furthest points from each other.

[0008] In a further alternative, the ion emitter is mounted at one end of the impeller, while the other end of the impeller is the far end.

[0009] In a further alternative, the blades of the impeller extend from the near end to the far end in a helical rotation manner.

[0010] In a further alternative, the fan assembly includes a duct for fixing the purification motor, and the air outlet assembly includes an air outlet grille, which is matched and installed with the duct.

[0011] In a further alternative, the air outlet grille is provided with a mounting part, and the ion emitter head is limited and installed within the mounting part.

[0012] As a further alternative, the duct is provided with an air inlet.

[0013] As a further alternative, the air vent grille is a directionally adjustable grille.

[0014] Meanwhile, this utility model also discloses an air conditioner, including a device body and an air curtain mounting groove disposed on the device body, wherein the air curtain mounting groove is provided with an air curtain structure of any one of the above-mentioned solutions.

[0015] In a further optional embodiment, the main body is also provided with a control board, which is provided with a main control module and an ion generation module. The main control module controls the start and stop of the purification fan, and the ion generation module controls the start and stop of the ion generation device.

[0016] Beneficial effects:

[0017] 1. The air outlet assembly is equipped with an ion generator, which includes an ion emitter. The blades of the purifier motor impeller have a proximal end near the ion emitter and a distal end away from the ion emitter, with the blades gradually decreasing in diameter from the proximal end to the distal end. This arrangement, when the purifier motor starts rotating, causes a change in airflow due to the change in blade size. The larger blades generate a larger airflow and air pressure, thus carrying the ions generated by the ion generator towards the end with a smaller airflow. This achieves uniform ion dispersion throughout the entire fan blade airflow duct, resulting in a relatively uniform ionized airflow.

[0018] 2. The fan blades of the purification motor extend from the near end to the far end in a spiral rotation pattern. The spiral blade layout can guide the airflow, making better use of the spiral effect to guide ions to the entire air outlet space, so that the airflow carrying purified ions is evenly distributed throughout the air outlet, thereby achieving uniform ion purification in the air outlet.

[0030] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this application are indicated by the following claims.

[0031] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims. Specific implementation method one:

[0033] This application discloses an air conditioner. In this embodiment, "air conditioner" is a broad concept, and all household appliances with wind regulation functions are within the scope of this application, such as range hoods, indoor air conditioners, kitchen air conditioners, exhaust fans, etc., which have air purification effects.

[0034] Specific reference Figures 1-3 As shown, this embodiment takes a range hood as an example. The solution also discloses a range hood 10 with air conditioning and purification effects, including a device body 11 and an air curtain mounting groove 12 disposed on the body 11. The air curtain mounting groove 12 is provided with an air curtain structure and a control board 13. The control board 13 is provided with a main control module 14 and an ion generating module 15. The main control module 14 controls the start and stop of the purification motor 16, and the ion generating module 15 controls the start and stop of the ion generating device 19.

[0035] The specific air curtain structure includes a fan assembly and an air outlet assembly. The fan assembly includes a purification motor 16 and an impeller 18. The air outlet assembly is equipped with an ion generator 19, which includes an ion emitter 20. The impeller 18 includes a rotating shaft and multiple sets of blades mounted on the shaft. The blades extend axially from the end near the ion emitter to the end away from the ion emitter, and the blade tip diameter gradually decreases from the near end to the far end. See details [link / reference needed]. Figure 2 As shown, the blade tip diameter refers to the distance h from the root of the blade connected to the shaft to the tip of the blade. For ease of understanding, this figure shows the tip diameter variation of a conventional blade shape.

[0036] In this embodiment, the ion emitter 20 is installed in the middle of the impeller 18, with the two ends of the impeller 18 being the far ends. The middle can be the midpoint or a central part close to or adjacent to the midpoint. The blades of the impeller 18 extend spirally from the near end to the far end. That is, the blades on the impeller 18 gradually decrease in size from the middle to both ends. Thus, when the impeller rotates, at the same rotation speed, the larger blades in the middle generate a larger airflow, while the smaller blades at both ends generate a relatively smaller airflow, and the corresponding wind pressure may be lower. In this way, the purified ions generated by the ion generator 19 will spread from areas with strong winds to areas with weaker winds, and be blown out from the air outlet of the entire air curtain structure.

[0037] The purification fan assembly includes a duct 17 that fixes the purification motor 16 and surrounds the entire impeller 18. The air outlet assembly includes an air outlet grille 21, which is matched and installed with the duct 18 to form a purification air duct. The air outlet grille 21 has a mounting part, and the ion emitter 20 is limited and installed within the mounting part. The duct has an air inlet. The air outlet grille 21 is a directional adjustable grille. This allows the ion-laden air to oscillate or blow out in a set direction. The purified ions are uniformly mixed inside before exiting through the air outlet grille 21, ensuring that the air exiting the grille contains primarily purified ions. This achieves the technical problem and corresponding technical effect solved by this solution. It achieves uniform ion dispersion throughout the fan blade airflow duct, resulting in a relatively uniform ion airflow and overall purification of the space corresponding to the air outlet. Specific Implementation Method Two:

[0039] See details Figure 4 As shown, the difference between this embodiment and the first specific embodiment is that the ion emitter 20 is installed at one end of the impeller 18, and the other end of the impeller 18 is the far end.

[0040] In other words, the blade size of impeller 18 gradually decreases from one end to the other.

[0041] At this time, the blades on the impeller 18 can be arranged in a uniform extension or in a spiral rotation manner. In this case, the ion emitter 20 is set at the end with the largest blade tip diameter. In this embodiment, it is set at the end closer to the fan. Compared with the case where it is set at the other end, this is beneficial to the torque balance during the rotation of the purification motor 16, ensuring the stability of rotation, thereby ensuring the balance of wind speed and ensuring the uniform distribution of ions.

[0042] This application provides an air curtain structure that can achieve uniform airflow and a kitchen air purification device equipped with the air curtain structure. It can achieve uniform mixing of ions emitted by the ion generator with the airflow of the fan and uniform airflow of the ionized air, effectively improving the sterilization effect of the ion generator on the airflow, thereby better purifying the airflow and the ambient air in the space.
