Description of the invention: [Technical field to which the invention pertains] In particular, it relates to a blower which can reduce the noise of a blower and improve the efficiency of use of electric energy. [Prior Art] Referring to Figures 1 and 2, the conventional one is too The central second-level system consists of a water supply main unit 9 (which can be ά p + (J horse ice water main boiler or hot water boiler) and a flash drive for driving cold air or hot air into the room. a fan 8, the water supply main unit 9 has a water outlet battalion 91 and an inlet water pipe 92, and a water heater or a hot water is output from the outlet pipe 91, and the air blower 8 includes a Μ» ^ ^ Fengji Pan 81, a temperature detecting module 82, a parent motor 83, a driving die day ^, a chess group 84, a control module 85 and a three-way valve 86. The tube 81 has a water inlet 811 and a water outlet 812. The two-way valve 86 is connected between the water supply main unit 9 and the fan coil 81. The water supply main unit 9 outputs ice water or hot water to the outlet pipe 91 to the Three-way valve The three-way valve 86 can be used as a water inlet 811 for a forest or hot water guide fan. Or returning to the water inlet pipe 92 of the water supply host 9. The temperature module 82 is installed indoors and detects the temperature in the room, and the module 85 receives the room temperature set by the user, and the driving module is The AC motor 83, the temperature detecting module 82 and the control module 85 are electrically connected, and the AC motor 83 is driven according to the room temperature measured by the temperature detecting module 82 and the room temperature set by the user. One of the three speeds, such as high speed, medium speed and low speed, drives a fan (not shown) to rotate, and the fan rotates to allow air to flow outside the fan coil 81 and enter the room. When the water supply host 9 1307763 When the ice water is turned off, the ice water entering the fan coil 81 lowers the temperature of the entire fan coil 81, and the air flowing outside the fan coil 81 exchanges heat with the fan coil 81. Cold air and cold air flow into the room to achieve the purpose of lowering the room temperature. Conversely, when the water supply host 9 takes out hot water, the purpose of raising the room temperature can be achieved. When the temperature detecting module 82 measures When the room temperature is different from the set room temperature, the driving module 84 is first The AC motor 83 is driven to rotate at a high rotation speed, and the measured room temperature is brought close to the set temperature in a fast-adjusting manner, and then the AC motor 83 is driven at a medium rotation speed or a low rotation speed to be measured in a fine adjustment manner. The room temperature gradually reaches the temperature set by the user. However, when the temperature detected by the temperature detecting module 82 has been lowered or raised to a room temperature of 3, and the driving module 84 has controlled the AC motor. In the state of low speed, (4) the AC motor 83 continuously drives the cold air or the hot air to be blown into the room at a low rotation speed and can no longer reduce the rotation speed. In order to prevent the room temperature from continuing to fall or rise, the blower 8 must utilize the The three-way valve % returns the ice water or hot water outputted from the water supply main unit 9 to the water supply host 9 to prevent the ice water or hot water from continuing to flow into the fan coil 81 and gradually increase the temperature of the fan is 81 or If it falls, it will not become cold air or hot air flowing through the fan coil μ, so that the blower 8 can only perform the air blowing operation in the room only without adjusting the temperature to maintain the room temperature at the set room temperature. m ...but when the measured room temperature reaches the set room temperature, the AC motor 83 is retracted and maintained at a low-speed air supply state, and the rotation speed cannot be reduced to approach the 〇, and the electric energy will continue to be consumed, but it is used for The electric energy for regulating the temperature is very small, and the power consumption of the 1307763 blower 8 is very low, and only about a waste of electric energy.

[The content of the invention is complicated.] The purpose of the present invention is to provide a blower that can reduce the efficiency of use of electrical energy. Monthly fan, suitable for connecting to a water supply host and connecting two "7 hosts out of ice water or hot water to adjust the room temperature, the blower package 3 fortunately, the test module, a control module, a fan coil , always flow and drive modules. The temperature is set to _ room temperature and the measured room temperature is output. The control module receives the set room temperature. The fan coil is connected to the water supply host, and the water flowing out of the water supply host is led back to the water supply host. The DC motor is used to drive air through the fan coil. The driving module is electrically connected to the temperature pre-measuring module, the control module and the DC motor, and adjusts the rotating speed of the DC motor according to the measured room temperature and the set room $ to make the measured room Room temperature at Wenda. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figure 3, a preferred embodiment of the air blower 3 of the present invention is suitable for introducing ice water or hot water of a water supply main unit 4 (which may be an ice water main machine, a machine or a hot water boiler) to adjust the indoor environment. The temperature of the blower 3 includes a fan coil 31, a temperature detecting module 32, a constant flow horse, a drive module 34, and a control module 2. The main unit 4 has an outlet pipe 41 and An inlet pipe 42 is connected to the outlet pipe 41 for discharging ice water or hot water. The fan coil μ has a water inlet 311 and a water outlet 312, and the water inlet 3U and the water outlet σ 312 respectively correspond to the water outlet pipe 41 and the water inlet pipe 42 of the water supply main unit 4. The detection module 32 detects the temperature of the room. The control module receives the set value of the temperature and the set value of the wind speed. The drive module 34 includes a processing unit 341 and a drive unit M2. The driving unit 342 can drive the DC motor 33 to rotate. The processing unit 341 is electrically connected to the temperature detecting module 32 and the g control module 35, and according to the temperature detecting module 32_ to the room temperature and The control module 35 receives the user's setting, and the driving unit 342 controls the speed at which the DC motor 33 drives a fan (not shown) to direct air to the fan coil 31 to become cold gas or Hot air 'and flows into the room to adjust the temperature in the room to the user's set value. In a preferred implementation of the present invention, the control module 35 can receive the user's air temperature and the required room temperature, and the three wind speeds are strong wind 307763, stroke and weak wind, respectively. 33 The speed values corresponding to the three-stage wind speed are 1200 rpm, 600 rpm and 300 rpm, respectively, but not limited thereto. § When the user does not determine the wind speed, the driving module 34 drives the DC motor 33 with a different acceleration within a certain time gate T1, so that the rotation speed reaches the rotation speed corresponding to the user-set wind speed, and is specified in the section. After the time τι, the rotation speed is automatically adjusted to maintain the room temperature at the temperature set by the user. In the preferred embodiment of the present invention, the driving module 34 sets the segment specific time T1 # to 10 minutes, but is not limited thereto. 4 is not corresponding to the change of the rotational speed of the DC motor under strong wind and weak wind, for example, if the right user sets the strong wind, the drive module 34 drives the DC motor 33 to make the rotation speed i fine with a higher acceleration, and at (7) After the minute, the DC motor 33 is driven, and its rotation speed is automatically adjusted to maintain the room temperature at the set value; and if the user sets the weak wind, the driving molds 3 and 34 drive the DC motor to rotate at a lower acceleration. The second motor is driven. After 1 minute, the DC motor 33 is driven, and the rotation speed is from = to maintain the room temperature at the set value. Although the reverse rotation of the DC motor will increase the noise, the user can adjust the temperature required by the hair to meet the needs of the user within a short period of time. When the wind speed is set, the drive module 34 automatically adjusts the rotational speed of the motor 33 to maintain the room temperature at M.

Therefore, the influence of the gas entering the room has adjusted the water supply host. The water, the conventional blower needs to use the three-way valve to guide the outflow machine 3 to the water supply host without the need for hot water. The air supply of the present invention can therefore eliminate the 'blocking, water or hot water flow to the fan coil 31, ^ "The cost and installation of the two-way valve is troublesome. Flowing horses = two__ group 34 is controlled according to the following flow 22, right no, then step 24 is performed. Go to step 3.

Step 29, if otherwise, the processing step 是 乂 24 is the processing unit. If yes, step 25 is performed, if otherwise, step:: is performed. The wind speed is determined by using the step tit unit 341 to determine the wind speed set by the user. If ^ ^ ^ 5 is strong, then step 26 is performed; if the user's wind speed is stroke, the right wind speed is weak. The wind then proceeds to step 28^, if the user sets the step 26^>ν χ. The flow motor 33 is Γ, the processing unit 341 (four) the _ unit 342 causes the straight step 4 = wind' to proceed to step 21. /Processing early 341 controls the driving unit 342 to cause a stroke of the rotational speed of the straight 1307763 flow motor 33, and then proceeds to step 21. In step 28, the processing unit 341 controls the driving unit 342 to generate a weak wind in the rotational speed of the direct current motor 33, and then proceeds to step 21. In step 29, the processing unit 341 automatically adjusts the rotational speed of the DC motor 33 to bring the room temperature to a temperature set by the user, and then proceeds to step 21. Referring to Fig. 6, when the water supply host 4 outputs ice water, step 29 includes the following sub-steps: Sub-step 291 is that the processing unit 341 receives the room temperature set by the user, and then step 292 is performed. Sub-step 292 is that the processing unit 341 receives the measured room temperature, and then proceeds to step 293. Sub-step 293 is that the processing unit 341 calculates the temperature difference between the measured room temperature and the set room temperature, and then proceeds to step 294. Sub-step 294 is that the processing unit 341 determines the magnitude of the temperature difference. If it is less than 0 (indicating too cold), then step 295 is performed; if it is equal to 0, then step 296 is performed; if it is greater than 0 (indicating that it is not cold enough), then step 297 is performed. Sub-step 295 is that the processing unit 341 is proportionally integrated to cause the drive unit 342 to drive the DC motor 33 to decelerate. Sub-step 296 is that the processing unit 341 causes the drive unit 342 to maintain the speed of the DC motor 33 at a constant value. Sub-step 297 is that the processing unit 341 uses a proportional-integral technique to cause the drive unit 342 to drive the DC motor 33 to accelerate. 11 1307763 田》 When the water supply host outputs hot water, the processing step 294 of the generation spear is sub-step 294 corresponding to the change of the temperature difference, 1* ^ +t dragon is less than 0 (indicating that it is not enough) 297; If it is a column of I... illusion (* -,.. ' then proceed to step 296; if it is greater than 〇 (the table is not too hot) then proceed to step 295. It is worth noting that the fan (4) of this hair (4) can also Valve (not shown), and the connection of the two S-doors, the fan coil 31 and the water supply main unit 4, and the conventional central air-conditioning and/or the door-to-door The fan of the SiS is the same, and the hot water output from the water supply main unit 4 is returned to the water supply main unit 4 by the three-way valve, so that the temperature of the fan coil 31 can be lowered. Or the temperature is too low, the speed of the rectus motor 33 can be adjusted to be very low, and the %-μ blower 3 can more accurately maintain the chamber at the set value. Therefore, the =, _ valve is not necessary for the blower of the present invention; When the three-way valve is omitted, the manufacturing cost of the fan 3 is further reduced to reduce the present invention. In addition, since there are many other ways in the industry to drive the speed of the straight motor 33, the driving module 34 can also drive the DC horse 33 to adjust the temperature to a room temperature set by the user. It is not limited to the flow shown in FIGS. 5 and 6, as long as the DC motor 33 can be adjusted to a very low rotational speed in a stepless shifting manner. 'It is worth noting that the drive module 3 of the blower 3 of the present invention According to the above, the blower 3 of the present invention includes the DC motor % and can reduce the rotation speed of the DC stirrup 33 to a low level, thereby improving the use efficiency of electric energy, and since the drive module 34 is in a segmentless manner The DC motor 33 is driven in a shifting manner, so that the noise generated when the DC motor 33 switches the rotational speed is small, 12 1307763 instead: the ice water or the hot water output from the water supply main unit 4 is returned to the eye by eliminating a three-way valve. The drive module 34 can reduce the rotational speed of the DC motor 33 to a low level so that the flow rate of the cold air or hot air can be made low to almost no influence on the temperature in the room. Therefore, the object of the present invention can be achieved. The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention to the extent that it is simple to make the contents of the invention according to the invention. The equivalent change and the cultivation of Buddha are still within the scope of the patent of the present invention.
