Description

Technical Field

[0002] With the development of society, people have higher and higher requirements for comfort, and it is becoming more and more common to add efficient humidification functions to heating and cooling equipment. At present, humidifiers on the market can be divided into three categories according to their working principles: ultrasonic humidifiers, electric heating humidifiers and evaporative humidifiers. Ultrasonic humidifiers need to use pure water. If tap water is used, white powder will occur, and the impurity particles in the water will be deposited indoors; electric heating humidifiers use high temperature heating to evaporate water, and the humidification capacity is large, but the energy consumption is high and there are certain safety risks; the principle of evaporative humidifiers is natural evaporation, and the water on the humidification component is taken away by the fan to achieve the humidification effect. At the same time, the filter can filter impurities in the water and bacteria and dust in the air, which is very friendly to human health and comfort. The disadvantage is that the humidification capacity is low. For the humidification module used in heating and cooling equipment, the evaporative humidification with the best comfort should be given priority. In the face of the gradual miniaturization of heating and cooling equipment, how to effectively use the limited space inside the heating and cooling equipment to achieve a large humidification capacity has become a technical problem that needs to be solved urgently at this stage.

[0017] The beneficial effects of the present application are as follows: evaporative humidification achieves the purpose of humidification by carrying away the moisture in the humidifying component through airflow, and the humidifying component itself has a large resistance, so it is necessary to design the parameters of the humidifying duct composed of a shell, a water receiving component, a humidifying component and an airflow driving component.

[0024] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0025] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it 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. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0027] like Figure 1-Figure 4 As shown, the present embodiment provides a humidification air duct structure, comprising: a shell 1, a humidification component and an airflow driving component 4, the interior of the shell 1 comprising a first inner wall; the humidification component is installed in the interior of the shell 1, and a first air duct 7 is formed between the humidification component and the first inner wall; the humidification component comprises a water receiving part 2 and a humidification component 3, the humidification component 3 is placed in the water receiving part 2, and the upper part of the first air duct 7 is provided with a first air guide portion 9, the first air guide portion 9 comprises a first vertical surface arranged parallel to the end surface of the humidification component 3, and a first air guide inclined surface formed by obliquely extending from the first vertical surface toward the first inner wall surface; the airflow driving component 4 is installed above the humidification component 3.

[0028] Based on the above scheme, the housing 1 serves as the outer frame of the entire humidification air duct structure, providing installation space for the internal components. The first inner wall is a wall surface inside the housing 1, and a first air duct 7 is formed between the housing 1 and the humidification component. The water receiving part 2 is used to hold water and provide the humidification component 3 with the moisture required for humidification. The humidification component 3 is placed in the water receiving part 2 and at least partially extends out of the top of the water receiving part 2 so that it can contact the passing airflow to achieve the humidification effect. The upper part of the first air duct 7 is provided with a first air guide 9. This design is crucial for optimizing the airflow distribution and humidification effect, because the first air guide 9 includes a first vertical surface arranged parallel to the end surface of the humidification component 3, and a first air guide inclined surface extending obliquely from the first vertical surface toward the first inner wall surface. Such a design can guide the airflow to pass through the humidification component 3 more effectively, increase the contact area and time with the humidification component 3, and thus increase the humidification amount. The airflow driving component 4 is installed above the humidification component 3 and is responsible for generating or driving the airflow through the first air duct 7. When the airflow passes through the humidification component 3, it will take away the moisture on the humidification component 3 to achieve the humidification effect. The working principle of the humidification air duct structure is: when the airflow drive component 4 is started, it will generate or drive the airflow through the first air duct 7. The airflow first passes through the first air guide 9, is guided by the first air guide slope and the first vertical surface, and flows to the humidification component 3 more effectively. When the airflow flows through the humidification component 3, it will contact the moisture on the humidification component 3, take away the moisture, and form a humidified airflow. The humidified airflow is then discharged through other air ducts or outlets and enters the space that needs to be humidified. In this solution, the design of the first air guide 9 can optimize the airflow distribution, so that the airflow can contact the humidification component 3 more effectively and increase the humidification amount. At the same time, through a reasonable humidification air duct design, the humidification air duct structure can effectively solve the technical problem of insufficient humidification amount existing in the prior art.

[0029] In addition, the interior of the shell 1 also includes a second inner wall opposite to the first inner wall, a second air duct 8 is formed between the humidification component and the second inner wall, and a second air guide portion 10 is provided at the upper part of the second air duct 8. The second air guide portion 10 includes a second vertical surface arranged parallel to the other end surface of the humidification component 3, and a second air guide inclined surface formed by extending obliquely from the second vertical surface toward the second inner wall surface. As the other wall opposite to the first inner wall in the shell 1, a second air duct 8 is formed between the humidification component and the second inner wall. This symmetrical or quasi-symmetrical design helps to improve the uniformity of airflow distribution, thereby further improving the humidification effect. It is formed between the humidification component and the second inner wall. Similar to the first air duct 7, it also provides a path for the airflow to flow through the humidification component 3. Due to the existence of two air ducts, the airflow can flow through the humidification component 3 from two different directions, further increasing the contact area and contact time between the humidification component 3 and the airflow, which helps to improve the humidification effect. It is located in the upper part of the second air duct 8, and its design principle is similar to that of the first air guide part 9. The second air guide part 10 includes a second vertical surface arranged parallel to the other end face of the humidification component 3, and a second air guide inclined surface formed by extending obliquely from the second vertical surface toward the second inner wall surface. Such a design can guide the airflow to pass through the humidification component 3 more effectively, and work together with the first air guide part 9 to achieve a more uniform and efficient humidification effect. When the airflow driving component 4 is started, it will generate or drive the airflow to pass through the first air duct 7 and the second air duct 8 at the same time. The airflow first passes through the first air guide part 9 and the second air guide part 10 respectively, and is guided to flow toward the humidifier 3. Due to the existence of the two air guide parts, the airflow can flow through the humidifier 3 more evenly, thereby increasing the contact area and time with the humidifier 3. When the airflow flows through the humidifier 3, it will come into contact with the moisture on the humidifier 3, take away the moisture, and form a humidified airflow. The dual air duct design can increase the contact area and contact time between the airflow and the humidifier 3, thereby increasing the humidification amount. The combined action of the first air guide part 9 and the second air guide part 10 can make the airflow flow through the humidifier 3 more evenly, further improving the uniformity of the humidification effect.

[0030] Furthermore, the maximum horizontal spacing of the second air duct 8 is y, and an angle β is formed between the second air guide slope and the vertical plane, and there is a proportional relationship between β and y, wherein 5°≤β≤45°. The maximum horizontal spacing refers to the maximum width or spacing of the second air duct 8 in the horizontal direction. The size of this spacing will affect the flow state of the airflow in the second air duct 8 and the contact area between the airflow and the humidifier 3. The angle β is the angle between the second air guide slope and the vertical plane. The size of this angle determines the direction and intensity of the airflow guided by the air guide slope. The proportional relationship between β and y, when y increases, β also increases accordingly, which means that as the horizontal spacing of the second air duct 8 increases, the inclination angle of the air guide slope will also increase, so as to more effectively guide the airflow through the humidifier 3. This design can ensure that in the second air duct 8 of different widths, the airflow can be effectively guided to the humidifier 3, thereby maintaining the stability and consistency of the humidification effect. The value range of the angle β is 5°≤β≤45°. This range ensures that the air guide slope is neither too flat, resulting in poor guiding effect, nor too steep, resulting in excessive concentration of airflow. Within this range, the second air guide slope can provide a suitable guiding angle so that the airflow can be evenly distributed when passing through the humidifier 3, thereby improving the humidification effect. Considering practical applications, when designing the humidification duct structure, it is necessary to determine the maximum horizontal spacing y of the second air duct 8 according to specific application scenarios and requirements. For example, in a scenario where a larger amount of humidification is required, the value of y can be appropriately increased. At the same time, it is also necessary to adjust the size of the angle β according to the value of y to ensure that the airflow can be effectively guided to the humidifier 3. In the actual manufacturing and installation process, it is also necessary to pay attention to maintaining the smoothness and precision of the air guide slope to ensure that it can achieve the best guiding effect.

[0031] Furthermore, the maximum horizontal spacing of the first air duct 7 is x, and an angle α is formed between the first air guide slope and the vertical plane, α is directly proportional to x, the thickness of the humidifier 3 is t, α is inversely proportional to t, and 20°≤α≤60°. Since the maximum horizontal spacing x of the first air duct 7 is greater than the maximum horizontal spacing y of the second air duct 8, the angle α needs to be designed to be greater than β in order to better guide the airflow to the humidifier 3. In addition, when the heat exchange surface is fixed, that is, the length and height of the humidifier 3 are confirmed, the thickness a of the humidifier 3 is inversely proportional to the angle α. The larger the angle of the first guide slope, the smaller the thickness of the humidifier 3 can be, and the better the diversion effect, the thinner it is, but the transition diversion will cause the wind to be unable to enter the entrance of the airflow drive component 4, so α has a range limit.

[0032] On the other hand, a cooling and heating device is also provided, including a humidification air duct structure as described in any of the above items. In this solution, the humidification air duct structure is mainly used in the cooling mode, because the cold air output in the cooling mode is relatively dry, so it is necessary to set a humidification air duct structure in the unit. Before the cold air is output, the cold air is first humidified by the above-mentioned humidification component 3, and then enters the fan cavity from the second air inlet of the airflow drive component 4, and then is discharged from the first air outlet 5, and then the humidified cold air is output to the indoor space.

[0033] Furthermore, a first air inlet is arranged below the water receiving part 2, and the first air inlet is connected to the first air duct 7 and the second air duct 8. The bottom of the airflow driving component 4 is the second air inlet, and a fan cavity is formed in the airflow driving component 4. The outer wall of the shell 1 is provided with a first air outlet 5, and the fan cavity is connected to the second air inlet and the first air outlet 5. The outer wall of the shell 1 is also provided with a second air outlet 6 spaced apart from the first air outlet 5, and the second air outlet 6 is connected to the first air duct 7 and is higher than the first air inlet in vertical height; the cooling and heating equipment includes a humidification mode and a non-humidification mode. When the humidification mode is operated, the first air inlet is the unit air inlet, the first air outlet 5 is the unit air outlet, and the second air outlet 6 is the unit return air outlet; when the non-humidification mode is operated, the first air inlet is the unit air inlet, and the second air outlet 6 is the unit air outlet.
