Description
Technical Field
[0001] The utility model belongs to the technical field of air ducts, and more specifically relates to a uniform air supply device for a constant temperature room. Background Art
[0002] In a constant temperature room, not only is it necessary to supply warm air of a preset temperature to the interior through air ducts to ensure the internal temperature is stable, but the temperature in each part of the constant temperature room must be similar (with a fluctuation of no more than one degree Celsius). This is because only the temperature of the space near the air duct outlet reaches the preset value, but the temperature of the space farther away from the air duct outlet is greatly different from the preset value.
[0003] In the prior art, a turbulent fan is usually added in the constant temperature room to enhance the temperature uniformity in various places in the room. However, this practice not only increases energy consumption, but also affects the temperature in the entire constant temperature room due to the heat dissipation of the turbulent fan, affecting the normal use of the constant temperature room.

A plurality of air dispersion members 30 are arranged at intervals in the circumferential direction of the mounting platform 20, and an air dispersion gap 31 for heating air to pass through is formed between two adjacent air dispersion members 30; the chassis 40 is arranged below the air dispersion member 30 in the horizontal direction, and the chassis 40 is connected to the lower edge of the air dispersion member 30.
[0020] The embodiment of the present application provides a uniform air supply device for a constant temperature room. During its actual use, the air duct 1 extends downward, and the air guide 10 is connected to the lower end (air outlet end) of the air duct 1. The plate surface of the air guide 10 extends in the up and down direction. After the warm air comes out from the air outlet end of the air duct 1, it enters between the chassis 40 and the mounting platform 20, and enters each air dispersion gap 31 under the separation of the air dispersion member 30, so as to be evenly diffused to the outer periphery of the chassis 40 to various places in the constant temperature room, thereby avoiding unnecessary energy consumption and ensuring the uniformity of temperature in various places in the constant temperature room, so as to use the constant temperature room normally.
[0021] Compared with the prior art, the uniform air supply device for the constant temperature room provided in the present embodiment is that after the warm air comes out from the air outlet end of the air duct 1, it enters between the chassis 40 and the mounting platform 20, and enters each air dispersion gap 31 separated by the air dispersion member 30, so as to be evenly diffused to the periphery of the chassis 40 to various places in the constant temperature room, thereby avoiding unnecessary energy consumption and ensuring the uniformity of temperature in various places in the constant temperature room so as to use the constant temperature room normally.
[0022] In a possible implementation, the wind dissipating member 30 is configured as follows: Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 The wind dispersing member 30 includes a rectangular sleeve 32 and a slide plate 33. The rectangular sleeve 32 is connected to the bottom surface of the mounting platform 20 and has a downward opening. The slide plate 33 is slidably connected in the rectangular sleeve 32. The lower edge of the slide plate 33 is connected to the chassis 40. The slide plate 33 is locked by the adjusting member 50.
[0023] Specifically, by adjusting the sliding fit of the slide plate 33 and the rectangular sleeve 32 and locking the position of the slide plate 33 by the adjusting member 50, the distance between the mounting platform 20 and the chassis 40 can be expanded, thereby adjusting the impact force of the warm air blowing out of the wind dispersion gap 31, that is, adjusting the diffusion area of the warm air, thereby improving practicality.
[0024] In some embodiments, see Figure 1 and Figure 2 The adjusting member 50 includes a connecting seat 51 and an adjusting screw 52. The connecting seat 51 is arranged between the air guide member 10 and the chassis 40, and the connecting seat 51 is connected to the rectangular sleeve 32; the adjusting screw 52 is rotatably connected to the connecting seat 51 and is downwardly penetrated through the chassis 40, and the adjusting screw 52 is threadedly connected to the chassis 40.
[0025] Specifically, by rotating the adjusting screw 52, the chassis 40 can be moved axially along the adjusting screw 52, that is, the extension length of the adjusting slide 33 in the rectangular sleeve 32 is adjusted. After the adjusting screw 52 stops rotating, the axial position of the chassis 40 can be locked, thereby improving the convenience of adjustment.
[0026] In some embodiments, see Figure 1 and Figure 2 A radially extending force rod 521 is provided at the lower end of the adjusting screw 52.
[0027] Specifically, when the adjusting screw 52 needs to be rotated, the staff only needs to hold the force applying rod 521 and rotate it to apply force, thereby improving practicality.
[0028] In a possible implementation, the air guide member 10 is configured as follows: Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 The air guide member 10 includes a connecting tube 11, an air guide tube 12 and a push sleeve 13. The connecting tube 11 is connected to the air outlet end of the air duct 1 and extends downward. A positioning groove 111 extending axially to the lower end of the connecting tube 11 is penetrated on the peripheral wall of the connecting tube 11; the air guide tube 12 is slidably connected in the connecting tube 11, and a positioning block 121 slidingly matched with the positioning groove 111 is provided on the outer peripheral wall of the air guide tube 12; the push sleeve 13 is threadedly sleeved on the outer periphery of the connecting tube 11 and is located on the side of the positioning block 121 close to the open end of the positioning groove 111. The push sleeve 13 can axially push the positioning block 121 to abut against the bottom wall of the positioning groove 111 to lock the axial position of the air guide tube 12.
[0029] Specifically, the upper end of the connecting pipe 11 is welded to the air outlet end of the air duct 1. The required length of the connecting pipe 11 is determined according to actual conditions. When in use, first align the positioning block 121 with the positioning groove 111, align the air guide pipe 12 with the connecting pipe 11, and insert the air guide pipe 12 into the connecting pipe 11, and then rotate the pushing sleeve 13 to push the positioning block 121 along the axial direction of the air guide pipe 12 until the positioning block 121 abuts against the bottom wall of the positioning groove 111, thereby completing the rapid installation of the air supply device and improving the installation efficiency.
[0030] During disassembly, the air supply device can be disassembled by simply rotating the push sleeve 13 and the connecting pipe 11 apart and pulling the air guide pipe 12 toward the lower end of the connecting pipe 11, thereby quickly disassembling the air supply device and improving disassembly efficiency.
[0031] In some embodiments, see Figure 1 and Figure 2 There are two positioning grooves 111 , which are symmetrically arranged on both sides of the central axis of the connecting pipe 11 , and there are two positioning blocks 121 , which are arranged one-to-one corresponding to the two positioning grooves 111 .
[0032] Specifically, the one-to-one corresponding plugging of the two positioning blocks 121 and the two positioning grooves 111 can improve the connection stability between the connecting pipe 11 and the air guide pipe 12 .
[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
