Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioning, and in particular relates to a distributed air duct system, a control method, an air conditioner, a medium and a terminal. Background Art

[0002] At present, with the popularity of air conditioners in households, simple cooling and heating can no longer meet the requirements of consumers. How to make consumers feel more comfortable when using air conditioners has become the focus of research by air conditioner manufacturers. In order to improve heating comfort and solve the problem of hot air not falling to the ground, split floor-standing air conditioners with upper and lower air outlets that simultaneously deliver air have been launched on the market. In heating mode, the air outlet acts as an auxiliary air outlet to blow out part of the hot air from the air outlet, which improves the problem of hot air not falling to the ground to a certain extent, but the design of the upper and lower air outlets also has some disadvantages.

[0003] 1. Since both the upper and lower air vents are blowing out hot air, for a period of time after the machine is turned on, the hot air blown out of the upper air vent will first gather in the upper space of the room, as the density of the hot air flow is smaller and the mass is lighter than that of the cold air in the room. The temperature of the upper space will rise first, and this part of the space is not the area where human activities take place. The area where human activities take place can only be heated up by the hot air from the lower air vent, but the air volume of the lower air vent is limited (at most half of the air volume of the whole machine), resulting in a slow temperature rise in the area where human activities take place. The customer then complained about the poor heating effect of the air conditioner. The after-sales service found that the air outlet temperature was normal when they came to check the air outlet. This problem is particularly obvious in the northern region in winter. The fundamental reason for the customer's complaint is that the air outlet method of the air conditioner is defective. After the air conditioner is turned on, it cannot blow all the hot air to the area where human activities take place, and cannot quickly raise the temperature of the area where human activities take place. The customer's comfort experience is poor, leading to customer complaints.

[0004] 2. Floor-standing air conditioners with upper and lower air vents. Since the lower air vent is designed to solve the problem of hot air not falling to the ground, the air vent is closed by default in the cooling mode, and only the upper air vent blows out cold air. Since the upper air outlet is small, the area where the air outlet is aimed at will be particularly cold, which will be very uncomfortable if it blows towards the human body. The area where the air outlet is not aimed at is relatively hot, so the temperature uniformity of the room is particularly poor, and the human comfort is also poor. In order to solve the problem of poor room temperature uniformity in cooling mode, there are also floor-standing cylindrical cabinets on the market that use cross-flow air ducts and super-large air outlet structure designs. This design of vertical large air outlets covers a large area in the vertical direction, and the temperature uniformity of the room in cooling mode will be better, but there is also the problem of hot air not falling to the ground in heating mode.

[0005] The development of the air duct structure of the cabinet, the first generation has only one upper air outlet, and the comfort experience is poor. The second generation adopts a cross-flow air duct design and an extra-large air outlet. Due to the vertical extra-large air outlet, the cooling and heating comfort experience is improved compared with the first generation, but there is still the problem of hot air not falling to the ground. The third generation adopts the design of two upper and lower air outlets, which focuses on solving the problem of hot air not falling to the ground. However, compared with the second generation structure with vertical extra-large air outlets, the air outlet coverage area is small and the temperature uniformity in the cooling mode is poor. This patent designs 4 groups of distributed air ducts, and corresponds to 4 groups of 4 vertically distributed air outlets. In the heating mode, all the hot air is blown out from the two air outlets below after the machine is turned on, which solves the problem of hot air not falling to the ground. At the same time, the air outlet has a certain thickness, which quickly increases the temperature of the human activity area and improves the human comfort. In the cooling mode, all 4 air outlets are opened after the machine is turned on, forming a vertical extra-large air outlet, which ensures the thickness of the air outlet in the vertical direction, quickly reduces the room temperature, and improves the room comfort.

[0006] Patent number CN104595976B discloses a split floor-standing air conditioner, which has two upper and lower air outlets. The air outlet of the two air outlets is achieved by opening and closing the wind shield. This design can solve the problem of hot air not falling to the ground in heating mode, but in cooling mode, cold air is blown out from the two air outlets. It is impossible to achieve large-scale vertical delivery of cold air like the cross-flow air duct and super-large air outlet structure design, and the cooling comfort experience is poor. The distributed air duct system designed by this patent opens the two lower air outlets in the heating mode to solve the problem of hot air not falling to the ground and ensure the heating comfort experience. In the cooling mode, by opening 4 air outlets, large-scale vertical delivery of cold air is achieved, which also ensures the cooling comfort experience.

[0007] Patent No. CN107965844A discloses an indoor unit of an air conditioner and a control method thereof, and an air conditioner. The air conditioner is designed with three air outlets, namely, upper, middle and lower. The middle air outlet is designed to allow the human body's trunk or thigh to feel hot air in the heating mode. The middle air outlet is spaced apart from the lower air outlet, and the hot air blown out is independent and cannot be closely connected with the hot air blown out of the lower air outlet to form a continuous hot air belt, which will affect the comfort experience of the entire human body. This design can solve the problem of hot air not falling to the ground in the heating mode and the comfort problem of some human bodies, but in the cooling mode, it cannot realize the large-scale vertical delivery of cold air like the cross-flow air duct and the super-large air outlet structure design, and the cooling comfort experience is poor. The distributed air duct system designed by this patent opens the two air outlets at the bottom in the heating mode to solve the problem of hot air not falling to the ground. At the same time, the air blown out of the two air ducts is continuous, which can make the human body feel a complete hot air belt, and the comfort experience is better than opening a single air outlet in the middle of the body. In cooling mode, by opening 4 air vents, cold air can be delivered vertically over a large area, ensuring a comfortable cooling experience.

[0008] Through the above analysis, the problems and defects of the existing technology are as follows: the existing floor-standing cabinet can only focus on solving one of the problems of hot air not falling to the ground in heating mode and small vertical air supply range in cooling mode, and cannot solve both problems of hot air not falling to the ground in heating mode and small vertical air supply range in cooling mode at the same time. Summary of the invention

[0009] In view of the problems existing in the prior art, the present invention provides a distributed air duct system, a control method, an air conditioner, a medium and a terminal. The present invention can solve the two problems of hot air not falling to the ground in the heating mode and the small vertical air supply range in the cooling mode by designing a distributed air duct system and using four independently controlled air outlets.

[0010] The present invention is implemented as follows: a control method with distributed air ducts is applied to an air conditioner, and the control method with distributed air ducts comprises:

[0011] Use multiple independently controlled air outlets on the front panel to control the range of vertical air supply in heating mode and cooling mode.

[0012] Furthermore, the volute wind shield plate and the volute guide plate are driven by a motor to flip, thereby controlling the opening or closing of the volute air outlet, and further controlling the opening or closing of the four air outlets on the front panel.

[0013] Further, when the air conditioner receives the instruction to stop the air outlet of the front panel, the guide plate of the volute air outlet corresponding to the front panel air outlet turns over, and when one side of the guide plate touches the air outlet wall plate, the guide plate stops turning over; then the wind shield plate of the volute air outlet corresponding to the front panel air outlet turns over, and when one side of the wind shield plate touches the edge of the volute air outlet below the guide plate, the wind shield plate stops turning over, and at this time, the wind shield plate completely blocks the volute air outlet, and the front panel air outlet is closed;

[0014] When the air conditioner receives the command to start discharging air from the front panel air outlet, the wind shield of the volute air outlet corresponding to the front panel air outlet flips over, and when the wind shield hits the vertical wall panel of the air outlet, the wind shield stops flipping; then the guide plate is flipped over, and when the guide plate hits the edge of the volute air outlet below the guide plate, the guide plate stops flipping. At this time, the volute air outlet is fully opened, and under the action of the guide plate, the air flow is blown out from the volute, and the front panel air outlet is closed.

[0015] Further, when using the cooling mode or heating mode, the opening and closing of any front panel air outlet is controlled as needed;

[0016] In cooling mode, all four air outlets on the front panel are opened after the machine is turned on. When the room temperature approaches the set temperature, the fourth air outlet on the front panel, the third air outlet on the front panel, and the second air outlet on the front panel are closed in order from bottom to top according to the room temperature.

[0017] When in heating mode, only the third and fourth air outlets on the front panel are opened after power on, and the second and first air outlets on the front panel are closed; when the room temperature approaches the set temperature, the third air outlet on the front panel is closed according to the room temperature.

[0018] Further, closing the fourth air outlet of the front panel, the third air outlet of the front panel, and the second air outlet of the front panel in order from bottom to top according to different room temperatures includes:

[0022] 0℃≤Room temperature-Set target temperature<1℃, open the first air outlet on the front panel, and close the fourth air outlet on the front panel, the third air outlet on the front panel, and the second air outlet on the front panel;

[0023] In the process that the room temperature approaches the set temperature, closing the third air outlet of the front panel at an appropriate time according to the room temperature includes:

[0024] Room temperature - set the target temperature ≥ 2°C, open the fourth and third air outlets on the front panel, and close the first and second air outlets on the front panel;

[0025] 0≤Room temperature-Set the target temperature<2℃, open the fourth air outlet on the front panel, and close the first air outlet, the second air outlet, and the third air outlet on the front panel.

[0026] Another object of the present invention is to provide a distributed air duct system for use in an air conditioner, the distributed air duct system comprising: a plurality of fan volute air outlets, a plurality of independent air ducts and a plurality of independent air outlets on a front panel;

[0027] A volute wind shield and a volute guide plate are provided at each volute air outlet;

[0028] The volute windshield is arc-shaped; a rotating shaft is provided at one end of the edge of the volute windshield, and a motor shaft hole is provided at the other end; the motor shaft hole is rectangular and is used to drive the windshield to flip through the cooperation of the motor shaft and the shaft hole;

[0029] A rotating shaft base is arranged on the wall plate in the vertical direction of the volute air outlet, and a stepping drive motor is fixed on the fan volute on the same horizontal line;

[0030] The volute guide plate is rectangular; one end of the guide plate has a rotating shaft and the other end has a motor shaft hole, and the motor shaft hole is rectangular; the installation position of the volute guide plate is parallel to the intersection line of the volute inner wall plate and the outlet inclined wall plate, and is at a certain distance from the intersection line;

[0031] The air ducts include: a fan volute air outlet and a front panel air outlet that are individually connected to each air duct;

[0032] The multiple air outlets on the front panel are arranged vertically from top to bottom.

[0033] Furthermore, a rotating shaft base is provided on the wall plate in the inclined direction of the volute air outlet, and a stepping drive motor is fixed on the fan volute on the same horizontal line; the installation position of the volute guide plate is parallel to the intersection line of the volute inner wall plate and the air outlet inclined wall plate, and is at a certain distance from the intersection line, so that the volute air outlet can be completely covered after the wind shield is closed;

[0034] There are four air ducts, the top and bottom air ducts of the four air ducts are arranged horizontally, and the middle two air ducts are arranged in an S-shaped staggered manner;

[0035] The distributed air duct system further includes: two sets of fan systems fixed on the fan bracket and arranged symmetrically up and down, used for individually controlling the air outlets of the four air outlets on the front panel;

[0041] Combining all the above-mentioned technical solutions, the advantages and positive effects of the present invention are as follows: in the heating mode of the present invention, opening the two lower air vents can ensure that the hot air falls to the ground (and at the same time can make all the hot air blown to the space where the human body is active), and in the cooling mode, opening all four air vents can realize the large-scale vertical delivery of cold air. The four independently controlled air outlets on the front panel of the present invention can more accurately control the air outlet of the space corresponding to each air outlet, and each air outlet can be opened or closed as needed, so that the air supply range is more precise. The four vertically arranged air outlets of the present invention can ensure the vertical air supply range and the air outlet thickness. The design of the four independent air ducts of the present invention reduces the wind field resistance and improves the air supply efficiency of the fan due to the smooth air ducts. The system evaporator resistance is reduced by 30%, and the heat exchange effect is improved by 50%. BRIEF DESCRIPTION OF THE DRAWINGS

The windshield is fixed to the wall plate in the vertical direction of the volute air outlet by using the windshield rotating shaft and the motor shaft hole.

[0065] Preferably, the volute guide plate is rectangular, and the guide plate will not hit the centrifugal fan blades when it is flipped to guide the air. There is a rotating shaft at one end of the edge of the guide plate and a motor shaft hole at the other end.

[0113] In this embodiment of the present invention, in cooling mode, preferably, after the machine is turned on, all four air outlets on the front panel are opened to ensure a large range of air supply in the vertical direction, thereby improving the temperature uniformity of the entire room. When the room temperature approaches the set temperature, the fourth air outlet 4, the third air outlet 3, and the second air outlet 2 of the front panel are closed from bottom to top in turn according to the room temperature. The specific control method is as follows;

[0114] Room temperature - set the target temperature ≥ 8°C, and open all 4 front panel air outlets;

[0115] 5℃≤room temperature - set the target temperature to <8℃, open the first air outlet 1, the second air outlet 2, and the third air outlet 3 on the front panel, and close the fourth air outlet 4 on the front panel;
