Description

Technical Field

[0001] This utility model relates to a humidifier. Background Technology

[0002] A humidifier consists of a water distributor and a wet film. The water distributor is located on top of the wet film and sprays water supplied by the water supply system evenly onto the surface of the wet film. Under the action of gravity, the water flows downward along the surface of the wet film, making the entire surface of the wet film layer wet and forming a uniform water film. When dry air passes through the humidifier, it exchanges heat and mass with the water film on the surface of the wet film, thereby achieving the purpose of humidification.

[0003] Traditional water distributors (specifically referring to wet membrane thickness less than 100mm) cannot efficiently and evenly spray water from the water supply system onto the wet membrane surface. When water is being distributed, if the water flow rate is low, some outlet holes will not have water flowing out. When the water flows downwards due to gravity, it is easily affected by the direction of air flow, and the water flows over the wet membrane and out of the wet membrane. In other words, some water does not flow onto the wet membrane and cannot achieve uniform distribution. Utility Model Content

[0004] The purpose of this invention is to provide a humidifier that solves the problem of uneven water distribution during water distribution, thereby improving the uniformity of water distribution and humidification efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A humidifier includes a water distributor and a wet membrane. The water distributor includes a water distribution box and a limiting guide. The water distribution box has a water-containing cavity, which is divided into an inlet cavity and an outlet cavity by a partition. The inlet cavity and the outlet cavity are distributed along the width direction of the water distribution box. The inlet cavity has a water inlet that communicates with a water source. The partition has a connecting hole that allows the inlet cavity and the outlet cavity to communicate with each other. The bottom outer surface of the outlet cavity has a protrusion that protrudes towards the wet membrane. The protrusion and the bottom side of the outlet cavity have corresponding water outlet holes that extend vertically and communicate with the outlet cavity. The wet membrane is located below the protrusion. The limiting guide is disposed below the water distribution box. The limiting guide is used to limit the movement of the wet film. There is a gap between the limiting guide and the upper end of the wet film, and the protrusion is located in the gap.

[0006] According to some embodiments of this utility model, in the length direction of the water distribution box, a plurality of protrusions are provided; and / or, in the width direction of the water distribution box, a plurality of protrusions are provided.

[0007] According to some embodiments of this utility model, the convex portion has a circular cross-section, and the water outlet hole has a circular cross-section.

[0008] According to some embodiments of this utility model, the diameter of the water outlet gradually decreases from top to bottom, or the diameter of the water outlet gradually increases from top to bottom.

[0009] According to some embodiments of this utility model, the partition includes a horizontal plate and a vertical plate, the horizontal plate and the vertical plate are L-shaped, the horizontal plate is connected to the inner bottom surface of the water-containing cavity, the vertical plate extends upward toward the inner top surface of the water-containing cavity, the vertical plate is provided with the connecting hole, and a gap is maintained between the top of the vertical plate and the inner top wall of the water-containing cavity.

[0010] According to some embodiments of this utility model, the partition plate is provided with a plurality of connecting holes, which are distributed along the length direction of the partition plate; the distance between the connecting holes on the partition plate and the bottom of the water-containing cavity is the same.

[0011] According to some embodiments of this utility model, the connecting hole on the partition is elongated and extends along the length of the water distribution box.

[0012] According to some embodiments of this utility model, the limiting guide is provided with a limiting groove with the opening facing downward, the upper end of the wet film is located in the limiting groove, the limiting groove is provided with a through hole for the protrusion to pass through, and the limiting guide has a U-shaped cross section.

[0013] According to some embodiments of this utility model, the limiting guide includes a first limiting member and a second limiting member that are independent of each other. The first limiting member and the second limiting member are respectively disposed on both sides of the wet film. A gap is maintained between the first limiting member and the second limiting member. The protrusion is located in the gap. Both the first limiting member and the second limiting member are L-shaped.

[0014] According to some embodiments of the present invention, the humidifier further includes a baffle, which is located in the gap between the limiting guide and the upper end of the wet film. One end of the baffle is connected to the limiting guide, and the other end extends toward the wet film.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The humidifier provided by this utility model ensures that the water flow is more accurately directed vertically through the protruding water outlet to the relevant area of ​​the wet film, preventing the water flowing out of the water outlet from being carried to the outside of the wet film by the airflow channel.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] See Figures 1 to 6 The humidifier shown includes a water distributor and a wet film 7. The water distributor is located above the wet film 7 and includes a water distribution box and a limiting guide 6, wherein: The water distribution box includes a box body 2 and a cover 1 covering the box body 2. The box body 2 of the water distribution box has a water-containing cavity, which is divided into an inlet cavity 21 and an outlet cavity 22 by a partition 4. The inlet cavity 21 and the outlet cavity 22 are distributed along the width direction of the water distribution box, and the partition 4 extends along the length direction of the water distribution box. The inlet cavity 21 has an inlet that communicates with the water source and is equipped with an inlet valve 3. The partition 4 has a connecting hole 421, which allows the inlet cavity 21 and the outlet cavity 22 to communicate with each other. The bottom outer surface of the outlet cavity 22 has a protrusion 5 that protrudes towards the wet film 7. The protrusion 5 and the bottom side of the outlet cavity 22 have corresponding outlet holes 221 that communicate with the outlet cavity 22. The wet film 7 is located below the protrusion 5.

[0021] A limiting guide 6 is located below the water distribution box and is connected to the bottom of the corresponding water outlet cavity 22 of the water distribution box. The limiting guide 6 is used to limit the movement of the wet membrane 7, restricting its offset. Simultaneously, the wet membrane 7 can move along the limiting guide 6 when it is removed. There is a gap between the limiting guide 6 and the upper end of the wet membrane 7 (this gap forms an airflow channel a), and the protrusion 5 is located in the gap. This gap ranges from 2 to 3 mm, ensuring smooth movement of the wet membrane 7 along the limiting guide 6. If the limiting guide 6 abuts against the upper surface of the wet membrane 7, it will be difficult to remove the wet membrane 7. In addition, the limiting guide 6 also serves to block and change the wind direction, preventing the wind from passing directly through the water distribution box and the upper end of the wet membrane 7, thus avoiding the water exiting the outlet hole from deviating from the wet membrane 7.

[0022] In this example, the humidifier includes a fan. The air blown out by the fan flows out in two directions, namely airflow direction a and airflow direction b. Airflow direction a flows from the bottom of the water inlet chamber 21 of the water distribution box to the top of the wet film 7 and the right side of the wet film 7. Airflow direction b flows from the bottom of the water inlet chamber 21 of the water distribution box and along the thickness direction of the wet film 7 (from the left side of the wet film 7 to the right side of the wet film 7 to penetrate the wet film 7). The function of the air is to carry away the moisture on the wet film 7.

[0023] In this example, the partition 4 divides the water-containing chamber into an inlet chamber 21 and an outlet chamber 22. Only the upper part of the inlet chamber 21 and the outlet chamber 22 are connected. The inlet and outlet are located on the two sides of the partition 4, respectively. Water enters the inlet chamber 21 through the inlet and accumulates in the inlet chamber 21. When the accumulated water level exceeds the lower part of the connecting hole 421 on the partition 4, it enters the outlet chamber 22 through the connecting hole 421 on the partition 4, and then is discharged to the wet membrane 7 through the outlet hole on the protrusion 5. Compared with the previous water-containing chamber, when the water volume in the water-containing chamber is small, it can flow into the outlet chamber 22 through the connecting hole 421 on the partition 4.

[0024] In this example, the advantage of setting up the protrusion 5 is that it avoids the water flow direction deviating from the wet membrane 7 due to the influence of the airflow channel a, thus preventing some water from entering the wet membrane 7 and failing to participate in humidification and prevent equipment leakage. It ensures that the water flow is more accurately directed vertically through the water outlet on the protrusion 5 to the relevant area of ​​the wet membrane 7, preventing water flowing out of the outlet chamber from being carried outside the wet membrane 7 by the airflow channel. This maintains the good operating condition of the equipment and reduces the potential for malfunctions caused by improper distribution of water flowing away from the wet membrane 7 to other components. Without the protrusion 5, the water flowing out of the outlet is far from the wet membrane 7 under the airflow a, failing to flow towards the wet membrane 7 and thus unable to perform humidification. Moreover, the flowing water is likely to cause machine leakage if it flows to other components.

[0025] Preferably, the partition 4 has a plurality of connecting holes 421, which are distributed along the length of the partition 4. The distance between the connecting holes 421 on the partition 4 and the bottom of the water-containing cavity is the same, that is, the lower part (421a) of the plurality of connecting holes 421 is located on the same horizontal plane. This method realizes the uniform and natural spread of water and avoids the water from flowing directly through the nearest water outlet, which would cause uneven flow.

[0026] In some embodiments, a plurality of protrusions 5 are provided along the length direction of the water distribution box; and / or, a plurality of protrusions 5 are provided along the width direction of the water distribution box.

[0027] In a preferred embodiment, the cross-section of the protrusion 5 is circular, and the cross-section of the water outlet is also circular. Alternatively, in some embodiments, the diameter of the water outlet gradually decreases from top to bottom, or gradually increases from top to bottom, increasing the water outlet surface area and facilitating rapid wetting of the wet film 7.

[0028] In some embodiments, the diameter of the protrusion gradually increases from top to bottom, which can better limit water deviation, that is, better allow water to flow directly to the wet film 7.

[0029] In this example, the partition 4 includes a horizontal plate 41 and a vertical plate 42. The horizontal plate 41 and the vertical plate 42 are L-shaped. The horizontal plate 41 is connected to the inner bottom surface of the water-containing cavity, and the vertical plate 42 extends towards the inner top surface of the water-containing cavity. A connecting hole 421 is provided on the vertical plate 42, and a gap is maintained between the top of the vertical plate 42 and the inner top wall of the water-containing cavity.

[0030] In some embodiments, the connecting hole 421 on the partition 4 is elongated and extends along the length of the water distribution box. Preferably, the connecting hole 421 on the partition 4 is an oval hole, which facilitates a larger flow of water to the outlet chamber 22.

[0031] In some embodiments, the limiting guide 6 has a downward-facing limiting groove, the upper end of the wet film 7 is located in the limiting groove, a gap is maintained between the upper end face of the wet film 7 and the inner top surface of the limiting groove, and the limiting groove has a through hole for the protrusion 5 to pass through. See [reference needed] Figure 1-2 The limiting guide 6 has an inverted U-shaped cross section, and the opposite side plates of the limiting groove are respectively set on both sides of the wet film 7.

[0032] In some implementations, see Figure 4-6 The limiting guide 6 includes a first limiting member 61 and a second limiting member 62 that are independent of each other. The first limiting member 61 and the second limiting member 62 are respectively disposed on both sides of the wet film 7. A gap is maintained between the first limiting member 61 and the second limiting member 62. The protrusion 5 is located in the gap. Both the first limiting member 61 and the second limiting member 62 are L-shaped.

[0033] Preferably, the humidifier further includes a baffle 8, which is located in the gap between the limiting guide 6 and the upper end of the wet film 7. One end of the baffle 8 is connected to the limiting guide 6, and the other end extends toward the wet film 7. The baffle 8 can be set on the left and / or right side above the wet film 7. The baffle 8 is located in the channel through which the airflow direction a passes. By setting the baffle 8 to prevent the airflow direction a from passing through the channel, there is no airflow a, only airflow b, which can better prevent the water flowing out of the water outlet of the protrusion 5 from deflecting away from the wet film 7.

[0034] In some embodiments, the baffle 8 is vertically or inclined. When the baffle 8 is inclined, if the baffle 8 is located on the upper left side of the wet film 7, the other end of the baffle 8 is inclined away from the upper right side of the wet film 7; if it is located on the upper right side of the wet film 7, the other end of the baffle 8 is inclined away from the upper left side of the wet film 7. The baffle 8 can abut against the upper surface of the wet film 7 in a straight line contact, so that the removal of the wet film 7 is not affected; or a reduced gap can be maintained between the baffle 8 and the upper surface of the wet film 7.

[0035] In this example, the thickness of the wet membrane 7 is less than 100mm, achieving efficient and uniform water distribution.

[0036] The advantages of the humidifier in this example are: 1. Improved water distribution uniformity: By combining partitions and protrusions, the problem of uneven water distribution in traditional water distributors is solved, ensuring that the evaporation components absorb water evenly throughout the entire area, avoiding fluctuations in humidification efficiency caused by local over-humidification or dryness.

[0037] 2. High resource utilization rate: The raised part prevents water from splashing out, and the water resource utilization rate reaches more than 98%, avoiding waste; at the same time, it protects the internal circuit of the humidifier and reduces the risk of equipment failure.

[0038] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
