Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of indoor air conditioning integrated device, especially, a kind of humidifying device can be integrated in air duct middle section and is used to output more suitable temperature and humidity air supply to indoor, belong to electromechanical application technical field. BACKGROUND

[0002] Current conventional humidifier, mainly steam humidification, ultrasonic humidification, wet membrane humidification etc., wherein steam humidification has direct steam humidification and the way of humidification using electrode heating municipal water to generate steam. Ultrasonic humidification is through using ultrasonic generator to oscillate liquid water into small droplets, and small droplets are mixed with air to be humidified, and naturally integrated into air to realize humidification. Wet membrane humidification is mainly through hydrophilic paper wet membrane to adsorb water on it, and then evaporate water vapor to the air flowing to realize humidification by natural evaporation.

[0003] The above can be summarized into two types: one is active humidification means, i.e. directly mixing gaseous water (water vapor) into dry air to achieve humidification; the other is relatively passive humidification means, i.e. letting liquid water evaporate naturally in the air, and the liquid water changes phase to become gaseous water, increasing the water content in dry air to achieve humidification.

[0004] The above-mentioned various humidification methods more or less have objective shortcomings. For example: the way of directly mixing gaseous water into dry air has the best humidification efficiency, but it needs a steam source first, and the steam needs to be clean, which is difficult to meet in most scenarios. The passive humidification method of liquid water has relatively low humidification efficiency; especially when the air temperature is low, the humidification efficiency is greatly reduced, which is difficult to meet the actual use demand. Electrode humidification essentially belongs to steam humidification, which solves the problem of humidification in scenarios without steam source, but the electrode barrel itself is a heat water consuming part that needs regular maintenance and replacement; especially for water quality, the water quality needs to have certain conductivity, but the conductivity cannot be too high, the applicable scenarios are also limited, and the energy consumption is high. Ultrasonic humidification also has relatively low efficiency, and is prone to cause water droplets to settle in pipeline or indoor, after the settled water droplets evaporate, the salts and other impurities dissolved in the liquid will leave "white powder" pollution on the surface. In addition to low efficiency, the wet membrane itself is mostly hydrophilic organic material such as paper, which has large wind resistance on one hand, and on the other hand, the surface will accumulate dust, bacteria and other pollutants during the humidification process, becoming a culture medium for microorganisms, causing secondary pollution of ventilation equipment.

[0017] Figure 2 is a side view structural schematic diagram of the preferred embodiment of the humidifying device of the utility model. DETAILED DESCRIPTION

[0018] The specific embodiments of the utility model will be further described in combination with the accompanying drawings, so that the technical scheme of the utility model is easier to understand and master, and the protection scope of the utility model is more clearly defined.

[0019] The designer of the utility model improves the many deficiencies in the implementation mode of the existing humidifying function added to the indoor ventilation equipment, and according to the specific technical improvement direction and performance pursuit, innovatively proposes a warm water type humidifying device, which is suitable for improving the ventilation and humidifying efficiency under the conditions of no steam source and conventional municipal water supply, and is convenient for maintenance and long-term stable operation.

[0020] As Figure 1 and Figure 2As shown in the structure perspective view of different view angles, the humidifying device has a cabinet 1 and two air inlets distributed along the front and rear direction of ventilation. As the technical improvement points, the cabinet 1 is externally connected with an electric control box 2, and the cabinet 1 is internally positioned and connected with a lower water collecting tray 3 and an upper water spraying tray 4. The lower water collecting tray 3 is provided with a stainless steel water guiding wire mesh 5 extending upward and reaching the bottom of the upper water spraying tray. The stainless steel water guiding wire mesh is inserted into the air duct and covers the entire cross section of the air duct. The lower water collecting tray 3 and the upper water spraying tray 4 are connected through a laterally arranged circulating water pipe 61 with a rapid heating hot water module 62 and a high temperature resistant water pump 63 driven by the electric control box. The liquid medium (not marked) in the lower water collecting tray 3 is driven to flow to the upper water spraying tray 4 and is heated by the rapid heating hot water module to warm water (40-65℃ is appropriate) in the middle of the figure. The upper water spraying tray 4 is provided with a plurality of leakage holes 41 distributed at the bottom, and the heated liquid medium is guided from the leakage holes to the stainless steel water guiding wire mesh 5 and backflows to the lower water collecting tray 3. Thus, a closed water circulation system is formed.

[0021] More importantly, the stainless steel water guiding wire mesh 5 is a block-shaped sieve body formed by interlaced welding of stainless steel strips, and the sieve body extends along the air duct for a ventilation stroke L. The ventilation holes formed by the sieve body satisfy the requirement that the airflow volume reduction rate is less than 3%. Based on the illustration, it can be understood that: the stainless steel strip is first curved in a prescribed shape such as wave, wave, spiral, etc. or in a special shape, and then interlaced to form a mesh sieve and welded at the contact points, thereby obtaining a three-dimensional block body with densely distributed ventilation holes and full-directional penetration. According to the specified size of the air duct in the cabinet, the stainless steel water guiding wire mesh is cut into a cylindrical or square cylindrical shape. When the liquid medium flows from the leakage hole to the water guiding wire mesh, the liquid droplets will flow downward along the surface tension of each stainless steel strip encountered. Since the stainless steel strip does not extend straight downward but extends obliquely and returns at the aforementioned multi-angle turning, the flow path of the liquid medium between the upper water spraying tray and the lower water collecting tray is greatly lengthened, thereby increasing the amount of vaporized warm water and reducing the downward flow rate and impact potential energy of the warm water.

[0022] Therefore, the humidifying device can use water sources or R0 water with water supply conditions available in most places for humidification, has a wide range of applications, and uses high temperature water to accelerate the evaporation rate of the liquid medium, thereby having high humidification efficiency. It can also effectively suppress the noise and water pollution caused by humidification operation.

[0023] As the detail optimization of the humidifying device, on one hand, the float ball type water level monitoring sensor 31 is arranged in the lower water accumulation tray 3 and signals are accessed to the electric control box 2, and the humidifying device is further provided with a water supplement port 64 with a solenoid valve, and the water supplement pipeline is externally connected to the municipal water supply. The solenoid valve is switched on and off by the electric control box, and the water supplement port can be supplemented with water facing the lower water accumulation tray. With the continuous humidifying operation, the water level in the lower water accumulation tray will gradually decrease, and when the consumed liquid medium reaches the preset lower limit of the water level, the solenoid valve can be controlled to be opened to supplement water to the lower water accumulation tray; and when the water level exceeds the preset upper limit, the solenoid valve is controlled to be closed. The electric control water supplement of the circulating water system is a common technical means in the field, and is not the main technical improvement point of the present application, so the function is limited as above.

[0024] On the other hand, under the condition that the ventilation and air supply quality is relatively good, the equipment needs to be maintained or reaches the preset water supplement circulation number according to the different water quality in different places, and the humidifying device can be kept idle for a period of time. In the preferred embodiment, the lower water accumulation tray is further provided with a drain port 65 through the circulating water pipeline. In the open state of the drain port, the liquid medium in the lower water accumulation tray is drained and discharged by the high-temperature resistant water pump, so as to avoid the deterioration of the water quality and the breeding of bacteria caused by long-term retention in the lower water accumulation tray. Here, when the high-temperature resistant water pump has the ability of bidirectional pressure drainage, only one high-temperature resistant water pump can be arranged; when it only has the ability of unidirectional pressure drainage, the circulating water supply and drainage need to be respectively arranged with a dedicated high-temperature resistant water pump.

[0025] On the other hand, the above-mentioned machine case 1 is provided with a negative ion sterilization module 7 facing the stainless steel water guide wire mesh 5, which is used to sterilize the stainless steel water guide wire mesh driven by the electric control box in the standby mode of the equipment. The machine case 1 is provided with a temperature and humidity sensor 8 connected to the electric control box on the inner wall close to the side air outlet, which can be used to monitor the real-time air temperature or humidity in front of or behind the air duct in the machine case. In addition, the above-mentioned rapid heating water module is an electric heater (electric heating wire, hot quick, etc.) sleeved outside the circulating water pipeline, and the electric heater is integrated with a display screen for displaying the heated temperature of the liquid medium outside the machine case.

[0026] On the other hand, the lower water accumulation tray 3 and the machine case are short cold bridges, which can avoid the heat transfer of the hot water in the humidifying mode to the machine case, causing energy waste.

[0027] The water type humidifying device can be freely matched with bidirectional flow exchange ventilation equipment or unidirectional flow ventilation equipment for indoor humidification. In order to interconnect with other equipment, the humidifying device is provided with air outlet flanges of external air pipes at two air outlet positions. In the preferred embodiment, when the humidifying device is applied to unidirectional flow ventilation equipment, the left side is defined as the air outlet 11 and the air outlet flange 91 is connected, and the right side is defined as the air inlet 12 and the air inlet flange 92 is connected. The air outlet 11 is further provided with a magnetic check valve 93.

[0028] From the above introduction and embodiment details of the warm water type humidifying device of the present application, it can be seen that it has substantial features and progress, and achieves the following technical effects: 1) the device introduces a stainless steel water guide screen into the air duct and sets a warm water circulation system based on the water guide screen, uses the metal surface to accelerate the vaporization rate of the warm water, and the warm water falls and flows along the water guide screen to the lower water accumulation tray, which can avoid water droplet noise and splashing to the outside of the water accumulation tray to pollute the air duct; 2) the contact area and time of the gaseous water and air are improved in the three-dimensional air duct created by the water guide screen, and the better heat conductivity of the water guide screen makes the heat transfer heat the air, especially for the dry and cold air in winter, thereby improving the capacity of the air to accommodate gaseous water, achieving the goal of rapid humidification and improving the supply air temperature; 3) the water guide screen made of inorganic material reduces the possibility of bacterial growth, and the built-in negative ion sterilization module and emptying the lower water accumulation tray at the time when humidification is not needed can prevent bacterial pollution hazards of the ventilation device in all directions.

[0029] In addition to the above embodiments, the present application can have other implementation manners, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
