Description

Technical Field

[0001] This application relates to an all-air system, and more particularly to an integrated humidifying evaporator device. Background Technology

[0002] A full-air system is a centralized air handling system. Outdoor fresh air and indoor return air are gathered at the full-air system main unit for temperature regulation, humidity regulation, filtration and purification, etc. The treated air is then transported from the main unit to different indoor spaces (such as different bedrooms and studies) through ducts.

[0003] Existing all-air humidification systems have the following drawbacks:

[0004] 1. Independent humidification modules require additional space in the air duct (such as electrode / heater / wet film humidifiers).

[0005] 2. Wet film humidification methods pose a risk of microbial growth;

[0006] 3. Traditional ultrasonic humidification is uneven and requires a separate water tank, increasing the overall thickness of the machine. Summary of the Invention

[0007] The technical problem to be solved by this application is: how to save space and achieve automatic humidification.

[0008] To solve the above-mentioned technical problems, this application provides an integrated humidifying evaporator device, which includes at least a motor, an air intake impeller driven by the motor, and at least one row of evaporator fins. The air intake impeller guides the incoming air to the at least one row of evaporator fins. At least one spray water pipe is arranged parallel above the at least one row of evaporator fins. Several spray nozzles facing the evaporator fins are evenly distributed on the at least one spray water pipe. The spray water pipe is connected to an external water source. The spray water pipe is controlled to open and close by a solenoid valve. The solenoid valve receives an external signal to control the opening and closing of the spray water pipe.

[0009] Furthermore, a housing is provided, with an air inlet window and an air outlet window that are connected at the front and rear. The housing is divided into an air inlet chamber and a condensation chamber by a partition. The motor and the air inlet impeller driven by the motor are placed in the air inlet chamber. The at least one row of evaporator fins, as well as the spray water pipe and spray water nozzle, are located in the condensation chamber. The partition has an air inlet corresponding to the number of air inlet impellers. The air outlet channel for the air inlet impellers is set at the air inlet to ensure that the incoming air is guided to at least one row of evaporator fins.

[0010] Furthermore, the bottom of the condensation chamber is provided with a drainage groove, and the drainage groove is further provided with at least one drainage pipe extending outward from the shell to drain the liquid deposited in the drainage groove.

[0011] Furthermore, the at least one row of evaporator fins and the spray water pipes are mounted on the shell at both ends.

[0012] Furthermore, a metal reinforcing plate is fixed to the outer wall of the shell, and the metal reinforcing plate is provided with an arc-shaped support groove corresponding to the refrigerant pipe of at least one row of evaporator fins. The external refrigerant pipe of at least one row of evaporator fins is placed in the arc-shaped support groove, which serves as a support bracket.

[0013] Furthermore, the angle between the spray nozzle and at least one row of evaporator fins is 30° to 90°.

[0014] Furthermore, the angle between the at least one row of evaporator fins and the extension direction of the air outlet channel of the air inlet impeller is 20° to 70°.

[0015] Furthermore, there is another control unit, which is used to collect indoor humidity data and compare it with preset low and high thresholds. When the humidity is less than or equal to the low threshold, a signal is sent to control the solenoid valve to open the spray pipe, and when the humidity is greater than or equal to the high threshold, a signal is sent to close the spray pipe.

[0016] This patent utilizes the evaporator device built into the all-air system, combined with its own characteristics, and adds a spray water pipe to the air intake. It further achieves condensation through the evaporator fins, and discharges condensed and humidified air. The control unit can monitor the indoor humidity to determine whether to turn on the spray water pipe, which effectively solves the humidification needs, and basically does not require much space or too many pipes. It is a better solution. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] An integrated humidifying evaporator device includes a motor 1, two air inlet impellers 2 driven by the motor 1 on both sides, and a row of evaporator fins 3. The air inlet impellers 2 guide the incoming air to the evaporator fins 3. A spray water pipe 4 is arranged parallel above the evaporator fins 3. Several spray nozzles 41 are evenly distributed on the spray water pipe 4 and face the evaporator fins 3. The spray water pipe 4 is connected to an external water source. The spray water pipe 4 is controlled to open and close by a solenoid valve. The solenoid valve receives an external signal to control the opening and closing of the spray water pipe 4.

[0022] In this embodiment, a housing 5 is provided, as shown in the figure. The housing 5 has an air inlet window 51 and an air outlet window 52 that are connected at the front and rear. The housing 5 is divided into an air inlet chamber 54 and a condensation chamber 55 by a partition 53. The motor 1 and the air inlet impeller 2 driven by the motor 1 are placed in the air inlet chamber 54. The evaporator fins 3, the spray water pipe 4, and the spray water nozzle 41 are located in the condensation chamber 55. The partition 53 has an air inlet 531 corresponding to the number of air inlet impellers 2. The air outlet channel 21 for the air inlet impellers 2 is installed in the air inlet 531 to ensure that the air is guided to the evaporator fins 3.

[0023] The bottom of the condensation chamber 55 is further provided with a drain groove 551, and the drain groove 551 is further provided with a drain pipe 552 extending outward from the shell 5. Most of the time, the spray nozzle 41 is located in the air inlet direction of the evaporator fins 3, that is, outside the air outlet channel 21 of the air inlet impeller 2. When the spray nozzle 41 sprays, it increases the humidity of the air inlet. At the same time, some water flows into the drain groove 551 and is discharged through the drain pipe 552.

[0024] like Figure 1 , 2 As shown, the two ends of the row of evaporator fins 3 and the two ends of the spray water pipes 4 are mounted on the housing 5. A metal reinforcing plate 56 is fixed to the outer wall of the housing 5. The metal reinforcing plate 56 has an arc-shaped support groove 561 corresponding to the refrigerant pipe 31 of the evaporator fins 3. The external refrigerant pipe 31 of the evaporator fins 3 is placed exactly in the arc-shaped support groove 561, which serves as a support bracket. In this embodiment, the solenoid valve is located outside the housing 5 and is further mounted on the upper part of the metal reinforcing plate 56.

[0025] like Figure 5 As shown, the angle between the spray nozzle 41 and at least one row of evaporator fins 3 is 30° to 90°; the angle between the row of evaporator fins 3 and the extension direction of the air outlet channel 21 of the air inlet impeller 2 is 20° to 70°, so that the sprayed water mist can better combine with the fresh air delivered by the air inlet impeller 2 over a large area, thereby improving the humidification effect.

[0026] Another control unit (not shown in the figure) is used to collect indoor humidity data and compare it with preset low and high thresholds. When the humidity is less than or equal to the low threshold, a signal is sent to control the solenoid valve to open the spray water pipe 4, and when the humidity is greater than or equal to the high threshold, a signal is sent to close the spray water pipe 4.

[0027] In some embodiments, if the evaporator fins 3 are in multiple rows, the spray pipe 4 is designed to be at a relatively high height to ensure that the water mist spray from the spray nozzle 41 can cover the multiple rows of evaporator fins 3.

[0028] The above embodiments and illustrations are not intended to limit the product form and style of this utility model. Any appropriate changes and modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
