Description

Technical Field

[0001] The utility model relates to the field of air conditioners, in particular to a humidity-adjusting and purifying device. Background Technique

[0002] Generally, in basements or indoor areas with high humidity and high temperature all year round, an air circulation device will be installed. This device improves the air quality in the basement by introducing fresh outdoor air and exhausting the dirty indoor air, and at the same time dehumidifying, so as to maintain the dryness and comfort of the indoor air. However, in existing air circulation devices, the air inlet and outlet are usually only set in the horizontal direction. If the air only circulates horizontally without vertical exchange, it may cause indoor temperature stratification, that is, there are differences in air temperature at different heights in the room, and the humidity may also vary due to uneven distribution during horizontal circulation. Some areas may be too humid while other areas may be relatively dry. In this case, to maintain indoor comfort, the operating time of heating or cooling equipment may need to be increased, which will lead to increased energy consumption. Content of the Utility Model

[0003] The purpose of the utility model is to provide a humidity-adjusting and purifying device to overcome the above-mentioned defects in the prior art.

[0004] A humidity-adjusting and purifying device according to the utility model includes a purification air conditioner and a mixed-flow fan. A turbid air inlet pipe for horizontal suction is fixedly connected to the purification air conditioner. An air inlet pipe is connected between the purification air conditioner and the mixed-flow fan. A return air pipe for horizontal suction of turbid air is fixed on the mixed-flow fan. A plurality of air outlet pipes for downward blowing are fixedly connected to the air inlet pipe. One end of the air outlet pipe for exhausting air, one end of the return air pipe for sucking air, and one end of the turbid air inlet pipe for sucking air are all located indoors.

[0005] Through the above technical solution, by arranging the return air pipe, the turbid air inlet pipe and the air outlet pipe in different directions, the overall circulation of indoor air can be promoted, so that the air flow is more evenly distributed in the space, reducing dead corners and improving the air exchange efficiency, thereby improving the indoor air quality, avoiding local overheating or overcooling, and improving the comfort of the indoor environment.

[0006] The utility model is further arranged as follows: return air openings and turbid air openings are respectively communicated at one ends of the return air pipe and the turbid air inlet pipe located indoors.

[0007] Through the above technical solution, the setting of the turbid air opening can intercept the dust in the turbid air, which is beneficial to filtering the turbid air and improving the indoor air quality. The setting of the return air opening is beneficial to absorbing the air discharged in the vertical direction into the mixed-flow fan for multiple recycling of the air.

[0008] The present utility model is further configured such that: the turbid air outlet is located directly below the return air outlet.

[0009] Through the above technical solution, dust in the air will settle downward under the influence of its own weight and is generally distributed in the lower area of the air. The turbid air outlet being located below the return air outlet is conducive to separating clean air and strengthening air circulation.

[0010] The present utility model is further configured such that: the exhaust ends of several of the air outlet pipes are horizontally equidistantly distributed, and several of the air outlet pipes are in the same vertical plane.

[0011] Through the above technical solution, the equidistant distribution of the air outlet pipes can make the air flow distribution in the vertical direction more uniform.

[0012] The present utility model is further configured such that: the exhaust end of the air outlet pipe is vertically downward, and the return air outlet and the intake end of the turbid air inlet are horizontally arranged.

[0013] Through the above technical solution, the exhaust end of the air outlet pipe being vertically downward maintains the air pressure balance in the vertical direction of the room and avoids the formation of concentrated air flow at the pipe orifice of the air outlet pipe. The horizontal arrangement of the return air outlet and the intake end of the turbid air inlet can ensure the horizontal flow of horizontal air and make the horizontal air evenly distributed in the room.

[0014] The present utility model is further configured such that: the inner diameter of the air outlet pipe gradually increases along the air flow direction.

[0015] Through the above technical solution, as the cross-sectional area of the pipe increases, the gas velocity flowing through the pipe decreases, reducing the discomfort caused by the high-speed air flow directly blowing on the human body.

[0016] The present utility model is further configured such that: the turbid air inlet pipe and the air inlet pipe are pipes made of stainless steel, and the return air pipe and the air outlet pipe are aluminum alloy pipes.

[0017] Through the above technical solution, the inner diameter surfaces of the stainless steel and aluminum alloy pipes are smooth and not easily adsorb dust, ensuring the quality of air circulation.

[0018] The beneficial effects of the present utility model are: by providing return air pipes, turbid air inlet pipes and air outlet pipes in different directions, it can promote the overall circulation of indoor air, make the air flow more evenly distributed in space, reduce dead corners, improve the air exchange efficiency, thereby improving the indoor air quality, avoiding local overheating or overcooling, and enhancing the comfort of the indoor environment.

[0027] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present utility model, and does not strictly limit the scope of protection of the specific claims of the present utility model. As used herein, the terms up and down and left and right do not refer to their strict geometric definitions, but include tolerances for machining or human error and inconsistencies. The specific features of the humidity control and purification device will be described in detail below:

[0028] An embodiment of the present utility model:

[0029] Refer to Figures 1-6, the present utility model provides a humidity-adjusting and purifying device, which includes a purification air conditioner 1 and a mixed-flow fan 2. A turbid air inlet pipe 4 for horizontal air suction is fixedly connected to the purification air conditioner 1. An air inlet pipe 5 is connected between the purification air conditioner 1 and the mixed-flow fan 2. The turbid air inlet pipe 4 and the air inlet pipe 5 are L-shaped stainless steel pipes. A return air pipe 3 for horizontal suction of turbid air is fixed on the mixed-flow fan 2. A plurality of air outlet pipes 6 for downward air blowing are fixedly connected to the air inlet pipe 5. The return air pipe 3 and the air outlet pipes 6 are aluminum alloy pipes. One end of the air outlet pipe 6 for exhausting air, one end of the return air pipe 3 for air suction, and one end of the turbid air inlet pipe 4 for air suction are all located indoors.

[0030] Reference Figure 1 , Figure 2 , at the indoor ends of the return air pipe 3 and the turbid air inlet pipe 4, a return air outlet 7 and a turbid air outlet 8 are respectively connected in a communicating manner. The setting of the air outlets increases the contact area between the pipes and the air, increasing the air flow rate in the pipes. The turbid air outlet 8 is conducive to discharging dust and other pollutants in the air outdoors, improving the indoor air quality. The return air outlet 7 absorbs the air discharged in the vertical direction into the mixed-flow fan 3, recycling the air multiple times. At the same time, the turbid air outlet 8 is directly below the return air outlet 7, which can better separate dust from clean air, facilitating the entry of dust into the turbid air outlet 8 and being discharged.

[0031] Reference Figure 2 , one end of the air outlet pipe 6 for exhausting air is vertically downward, and one end of the return air outlet 7 and the turbid air outlet 8 for air intake is horizontally arranged. The exhaust end is perpendicular to the return air outlet 7. This can maintain the air pressure balance in the vertical and horizontal directions indoors, avoiding the formation of concentrated airflows at the pipe orifice, causing air pressure differences and making people feel uncomfortable.

[0032] Reference Figure 3 , the exhaust ends of the air outlet pipes 6 are horizontally equally spaced. A plurality of the air outlet pipes 6 are in the same vertical plane. The equal spacing of the exhaust ends can make the air flow distribution more uniform, avoiding the increase of local air pressure caused by concentrated airflows and unstable air flow.

[0033] Reference Figure 6 , the inner diameter of the air outlet pipe 6 gradually increases along the air flow direction. As the cross-sectional area of the pipe increases, the gas velocity flowing through the pipe decreases, reducing the discomfort caused by the high-speed air flow directly blowing on the human body.

[0034] Outdoor air flows into the mixed-flow fan 2 through the air inlet pipe 5 after being dust-removed by the purification air conditioner 1. The mixed-flow fan 2 compresses the incoming air and transports it to the air outlet pipes 6. Air blows out from the vertically downward end of the air outlet pipes 6, forming a vertical air flow; the return air pipe 3 sucks the fresh air above the air blown out by the air outlet pipes 6 and returns it to the mixed-flow fan 2, forming a horizontal air flow. At the same time, the turbid air inlet pipe 4 sucks the turbid air with dust below and flows it into the purification air conditioner 1 for purification.

[0035] Those skilled in the art can clearly understand that various modifications to the above embodiments can be made without departing from the general spirit and concept of the present utility model. All of them fall within the protection scope of the present utility model. The protection scheme of the present utility model shall be subject to the appended claims of the present utility model.
