Description

Technical Field

[0001] The present invention relates to the technical field of heating, and in particular to a temperature control device for a heating system. Background Art

[0002] Existing heating systems use hot air sources such as fireplaces and furnaces to heat the air. For example, a fireplace is installed indoors and equipped with a fireplace heating system that draws in and heats the air. This heating system doesn't directly connect to the combustion chamber, but instead utilizes the heat from the combustion chamber to heat the air, which is then heated by a fan. Because the hot air generated by the fireplace can reach temperatures as high as 315°C, this can cause localized overheating in the room, resulting in uneven temperatures and discomfort for people inside.

[0003] For example, Chinese patent publication number CN104329718A, published on February 4, 2015, is entitled "A fireplace heating system for introducing and heating air from the outdoors." It includes an integral fireplace, which in turn includes a combustion chamber made of refractory bricks and a smoke exhaust duct connecting the inner cavity of the combustion chamber with the outdoor atmosphere. Except for part or all of the front surface of the combustion chamber, part or all of the remaining surfaces are wrapped with a fireplace shell made of steel plates, and a gap is left between the shell and the inner wall of the combustion chamber. It is characterized by: a duct for introducing air from the outdoors, an air inlet with a filter connected to the outdoors, and an air outlet leading to the indoors. The introduced air is heated by the back, sides, top or smoke exhaust duct of the fireplace and then delivered to the indoors by a fan.

[0004] The disadvantages of the existing patent are: the existing heating system directly heats the air through the fireplace for heating, and the hot air generated by the fireplace is too hot, causing the local temperature in the room to be too high, resulting in uneven indoor temperature and discomfort to the human body. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that the temperature of the hot air generated by the existing heating system through direct heating of the air by the fireplace is too high, which makes the local temperature in the room too high, causing uneven indoor temperature and human discomfort. The present invention provides a temperature control device for the heating system that can adjust the temperature of the hot air generated by the fireplace heating, so that the indoor heating is uniform and the indoor comfort is improved.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A temperature control device for a heating system includes a hot air source and a temperature control mixing device. The temperature control mixing device includes an air inlet pipe and an air outlet device. One end of the air inlet pipe is connected to the hot air source, and the other end is connected to a cold air pipe connected to the room. The air inlet end of the air outlet device is connected to the side wall of the air inlet pipe, and the air outlet end of the air outlet device is connected to the air outlet pipe connected to the room. A valve plate and a driving mechanism for driving the valve plate to rotate are provided in the air inlet pipe. The valve plate adjusts the air volume ratio of hot air and cold air entering the air outlet device. The temperature control device for a heating system described in this solution adjusts the temperature of the hot air generated by the hot air source through the temperature control mixing device to prevent the hot air source from directly providing too high hot air, causing the local temperature in the room to be too high, causing the human body to feel uncomfortable in the room. The temperature control mixing device is connected to the room through the cold air pipe. Under the action of the air outlet device, the cold air in the room is sucked in and mixed with the hot air generated by the hot air source to control the temperature of the mixed gas actually discharged into the room through the air outlet pipe. The outlet end of the air outlet pipe is arranged at the top of the room. There are one or more outlet ends of the air outlet pipe, so that the hot air discharged by the air outlet pipe can evenly heat the room, making the indoor heating uniform and improving human body comfort.

[0007] Preferably, the driving mechanism includes a rotating shaft, the valve plate rotates according to the rotating shaft, the central axis of the rotating shaft extends along the diameter direction of the air inlet pipe, and the rotating shaft is rotatably arranged on the side wall of the air inlet pipe.

[0008] Preferably, the valve plate is elliptical, the center of the ellipse of the valve plate is on the central axis of the air inlet pipe, the length of the short axis of the ellipse of the valve plate is the same as the diameter of the inner wall of the air inlet pipe, and the length of the long axis of the ellipse of the valve plate is greater than the diameter of the inner wall of the air inlet pipe; when the air inlet end of the air outlet device is only connected to the hot air source or the room, the edge of the valve plate is sealed with the inner wall of the air inlet pipe. Both ends of the long axis of the ellipse of the valve plate rotate in the air inlet pipe. The hot air source includes a hot air temperature sensor, which detects the temperature of the hot air output by the hot air source. According to the temperature of the hot air output by the hot air source and the actual heating temperature, the driving mechanism drives the valve plate to rotate and adjusts the air volume ratio of the hot air and the cold air entering the air outlet device, so as to control the temperature of the hot air and the cold air discharged into the room after mixing, so that the hot air discharged from the air outlet pipe can evenly heat the room, so that the indoor heating is uniform and the human body comfort is improved.

[0009] Preferably, the air inlet end of the air outlet device is connected to the side wall of the air inlet duct through a mixing air duct, the valve plate adjusts the air volume ratio of hot air and cold air entering the mixing air duct, the central axis of the air inlet duct, the central axis of the rotating shaft and the central axis of the mixing air duct have a common point and are arranged perpendicularly in pairs, and the radius of the mixing air duct is equal to the radius of the air inlet duct.

Since the central axis of the air inlet duct, the central axis of the rotating shaft and the central axis of the mixing air duct coexist and are arranged perpendicular to each other, the radius of the mixing air duct is equal to the radius of the air inlet duct, the semi-circular diameter of the valve plate is the same as the inner wall diameter of the air inlet duct, the short axis length of the semi-ellipse of the valve plate is the same as the inner wall diameter of the air inlet duct, the long axis length of the semi-ellipse of the valve plate is greater than the inner wall diameter of the air inlet duct, and the semi-elliptical edge of the valve plate is sealed with the junction of the air inlet duct and the mixing air duct, so that when the semi-ellipse of the valve plate rotates at the junction of the air inlet duct and the mixing air duct, the plug plate expands and contracts in the slot, so that the plug plate always cooperates with the inner wall of the air inlet duct, so that the part where the valve plate is provided in the air inlet duct is separated by the plug plate, and the hot air entering the air inlet duct will not enter the room through the cold air duct, so that the hot air can be better introduced into the air outlet device from the mixing air duct.

When the plug plate is fully retracted into the slot, the outer edge of the plug plate is sealed against the inner wall of the air intake pipe. The flexible layers on the upper and lower sides of the plug plate are compressed and retracted into the slot, allowing the plug plate to adapt to the inner wall of the air intake pipe.

[0012] Preferably, the air outlet device further comprises a temperature sensor for detecting the temperature of the mixture of hot air and cold air in the air outlet device. The temperature sensor detects the temperature of the air outlet device and cooperates with the hot air temperature sensor to control the temperature of the mixed gas in the air outlet device in real time.

[0026] Example 1, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 A temperature control device for a heating system shown in the figure includes a hot air source 1 and a temperature control mixing device. The temperature control mixing device includes an air inlet pipe 2 and an air outlet device 3. One end of the air inlet pipe 2 is connected to the hot air source 1, and the other end is connected to a cold air pipe 4 connected to the room. The air inlet end of the air outlet device 3 is connected to the side wall of the air inlet pipe 2, and the air outlet end of the air outlet device 3 is connected to an air outlet pipe 5 connected to the room.

The valve plate body 6.1 adjusts the air volume ratio of hot air and cold air entering the air outlet device 3.

[0027] The temperature control device for a heating system described in the above embodiment regulates the temperature of the hot air generated by a hot air source 1 through a temperature control mixing device, preventing the hot air source 1 from directly providing excessively hot air, which could result in localized excessively high temperatures in the room and cause discomfort to people inside. The temperature control mixing device connects to the room via a cold air pipe 4. Under the action of an air outlet 3, the device draws in cold air from the room and mixes it with the hot air generated by the hot air source 1 to control the temperature of the mixed air discharged into the room through an outlet pipe 5. The outlet end of the outlet pipe 5 is located at the top of the room, and there are one or more outlet ends of the outlet pipe 5. This allows the hot air discharged from the outlet pipe 5 to uniformly heat the room, ensuring uniform heating and improving human comfort. This device solves the problem of existing heating systems that directly heat air through a fireplace, generating excessively high temperatures in the room, causing localized excessively high temperatures and causing discomfort to people. This device provides a temperature control device for a heating system that can regulate the temperature of the hot air generated by a fireplace, ensuring uniform heating and improving human comfort.

[0028] In this embodiment, Figure 3 、 Figure 4 As shown, the driving mechanism 10 includes a rotating shaft 7, the valve plate body 6.1 rotates according to the rotating shaft 7, and the central axis of the rotating shaft 7 extends along the diameter direction of the air inlet pipe 2. The rotating shaft 7 is rotatably arranged on the side wall of the air inlet pipe 2.

[0029] Specifically, such as Figure 3 、 Figure 4 As shown, the valve plate body 6.1 is elliptical in shape, with the center of the ellipse of the valve plate body 6.1 on the central axis of the air inlet pipe 2. The length of the minor axis of the ellipse of the valve plate body 6.1 is the same as the inner diameter of the air inlet pipe 2, and the length of the major axis of the ellipse of the valve plate body 6.1 is greater than the inner diameter of the air inlet pipe 2.

Both ends of the major axis of the ellipse of the valve plate body 6.1 rotate within the air inlet pipe. The hot air source 1 includes a hot air temperature sensor, which detects the temperature of the hot air output by the hot air source 1. According to the temperature of the hot air output by the hot air source 1 and the actual heating temperature, the driving mechanism 10 drives the valve plate body 6.1 to rotate, and adjusts the air volume ratio of the hot air and the cold air entering the air outlet device 3, so as to control the temperature of the hot air and the cold air after being mixed and discharged into the room, so that the hot air discharged from the air outlet pipe 5 can evenly heat the room, so that the indoor heating is uniform and the human body comfort is improved.

[0030] Furthermore, the air inlet end of the air outlet device 3 is connected to the side wall of the air inlet pipe 2 through the mixing air duct 8, and the valve plate body 6.1 adjusts the air volume ratio of hot air and cold air entering the mixing air duct 8.

[0031] In this embodiment, the air outlet device 3 further includes a temperature sensor, which detects the temperature of the mixture of hot air and cold air in the air outlet device 3. The temperature of the air outlet device 3 is detected by the temperature sensor, and in conjunction with the hot air temperature sensor, the temperature of the mixed gas in the air outlet device 3 is controlled in real time.

[0032] Specifically, such as Figure 3As shown, the air outlet device 3 includes an air outlet housing 3.1 and a fan 3.2 arranged in the air outlet housing 3.1. The air outlet housing 3.1 is connected to the mixing air duct 8 and the room, and the mixing air duct 8 is coaxially arranged with the fan 3.2. The fan 3.2 discharges the mixed air into the room. The temperature control mixing device also includes a shell bracket 9. Both ends of the air inlet pipe 2 are supported on the shell bracket 9. The air outlet device 3 is supported in the shell bracket 9 through a partition. The side wall of the shell bracket 9 is provided with a heat dissipation hole 9.1. The heat dissipation hole 9.1 passes through the inside and outside of the shell bracket 9, and some of the heat dissipation holes 9.1 are located on the shell bracket 9 corresponding to the position of the drive motor.

The temperature control mixing device includes an air inlet pipe 2 and an air outlet device 3. One end of the air inlet pipe 2 is connected to the hot air source 1, and the other end is connected to a cold air pipe 4 connected to the room. The air inlet end of the air outlet device 3 is connected to the side wall of the air inlet pipe 2, and the air outlet end of the air outlet device 3 is connected to an air outlet pipe 5 connected to the room. A valve plate body 6.1 and a driving mechanism 10 for driving the valve plate body 6.1 to rotate are provided in the air inlet pipe 2. The valve plate body 6.1 adjusts the air volume ratio of hot air and cold air entering the air outlet device 3.

[0034] In this embodiment, Figure 3 As shown, the driving mechanism 10 includes a rotating shaft 7, the valve plate body 6.1 rotates according to the rotating shaft 7, and the central axis of the rotating shaft 7 extends along the diameter direction of the air inlet pipe 2. The rotating shaft 7 is rotatably arranged on the side wall of the air inlet pipe 2.

[0035] Specifically, such as Figure 5 、 Figure 6As shown, the valve plate body 6.1 is elliptical in shape, with the center of the ellipse of the valve plate body 6.1 on the central axis of the air inlet pipe 2. The length of the minor axis of the ellipse of the valve plate body 6.1 is the same as the inner diameter of the air inlet pipe 2, and the length of the major axis of the ellipse of the valve plate body 6.1 is greater than the inner diameter of the air inlet pipe 2. When the air inlet end of the air outlet device 3 is connected only to the hot air source 1 or the room, the edge of the valve plate body 6.1 seals against the inner wall of the air inlet pipe 2. Both ends of the major axis of the ellipse of the valve plate body 6.1 rotate within the air inlet pipe. The hot air source 1 includes a hot air temperature sensor, which detects the temperature of the hot air output by the hot air source 1. According to the temperature of the hot air output by the hot air source 1 and the actual heating temperature, the driving mechanism 10 drives the valve plate body 6.1 to rotate, and adjusts the air volume ratio of the hot air and the cold air entering the air outlet device 3, so as to control the temperature of the hot air and the cold air after being mixed and discharged into the room, so that the hot air discharged from the air outlet pipe 5 can evenly heat the room, so that the indoor heating is uniform and the human body comfort is improved.

[0036] In this embodiment, Figure 5 、 Figure 6As shown, the air inlet end of the air outlet device 3 is connected to the side wall of the air inlet pipe 2 through the mixing air duct 8, and the valve plate body 6.1 adjusts the air volume ratio of hot air and cold air entering the mixing air duct 8. The central axis of the air inlet pipe 2, the central axis of the rotating shaft 7 and the central axis of the mixing air duct 8 have a common point and are arranged perpendicularly in pairs. The radius of the mixing air duct 8 is equal to the radius of the air inlet pipe 2. The valve plate body 6.1 includes a valve plate body 6.1 body and an insert plate 6.2 inserted on one side of the valve plate body 6.1 body. A slot 6.1.1 is provided on one side of the valve plate body 6.1 body, and an elastic member 6.3 is provided in the slot 6.1.1. The insert plate 6.2 presses the elastic member 6.3 into the slot 6.1.1; one side of the valve plate body 6.1 body on which the insert plate 6.2 is provided is semicircular, and the other side is semi-elliptical. The diameter of the semicircular shape of the valve plate body 6.1 is the same as the inner wall diameter of the air inlet pipe 2; when the air inlet end of the air outlet device 3 is only connected to the hot air source 1 or the room, the edge of the valve plate body 6.1 is sealed with the junction of the air inlet pipe 2 and the mixing air duct 8. Since the central axis of the air inlet pipe 2, the central axis of the rotating shaft 7 and the central axis of the mixing air pipe 8 are co-pointed and arranged perpendicularly in pairs, the radius of the mixing air pipe 8 is equal to the radius of the air inlet pipe 2, the diameter of the semicircular shape of the valve plate body 6.1 is the same as the inner wall diameter of the air inlet pipe 2, the short axis length of the semi-elliptical shape of the valve plate body 6.1 is the same as the inner wall diameter of the air inlet pipe 2, the long axis length of the semi-elliptical shape of the valve plate body 6.1 is greater than the inner wall diameter of the air inlet pipe 2, and the semi-elliptical shape of the valve plate body 6.1 is equal to the inner wall diameter of the air inlet pipe 2. The edge is sealed and matched with the junction of the air inlet pipe 2 and the mixing air duct 8, so that when the semi-elliptical shape of the valve plate body 6.1 rotates at the junction of the air inlet pipe 2 and the mixing air duct 8, the plug plate 6.2 is extended and retracted in the slot 6.1.1, so that the plug plate 6.2 is always matched with the inner wall of the air inlet pipe 2, so that the part of the air inlet pipe 2 where the valve plate body 6.1 is provided is separated by the plug plate 6.2, and the hot air entering the air inlet pipe 2 will not enter the room through the cold air pipe 4, so that the hot air can be better introduced into the air outlet device 3 from the mixing air duct 8.

When the air volume ratio of hot air and cold air in the air outlet device 3 is 1:1, the elastic member 6.3 is in a compressed state, and the plug plate 6.2 is completely retracted in the slot 6.1.1. The plugboard 6.2 includes a plugboard 6.2 body and a flexible layer wrapped around the outside of the plugboard 6.2 body. The flexible layer allows the upper and lower ends and the outer edge of the plugboard 6.2 to be elastically set. In the actual setting, the outer edge of the plugboard 6.2 is semi-elliptical, and the major axis length of the semi-ellipse is greater than the diameter of the air intake pipe, so that the flexible layer is in a compressed state to achieve a good sealing effect. When the plugboard 6.2 is completely retracted into the slot 6.1.1, the outer edge of the plugboard 6.2 is sealed with the inner wall of the air intake pipe, and the flexible layers on the upper and lower sides of the plugboard 6.2 are compressed and retracted into the slot 6.1.1, so that the plugboard 6.2 adapts to the inner wall of the air intake pipe.

[0038] The temperature control device for a heating system described in the above embodiment regulates the temperature of the hot air generated by a hot air source 1 through a temperature control mixing device, preventing the hot air source 1 from directly providing excessively hot air, which could result in localized excessively high temperatures in the room and cause discomfort to people inside.

Under the action of an air outlet 3, the device draws in cold air from the room and mixes it with the hot air generated by the hot air source 1 to control the temperature of the mixed air discharged into the room through an outlet pipe 5. The outlet end of the outlet pipe 5 is located at the top of the room, and there are one or more outlet ends of the outlet pipe 5. This allows the hot air discharged from the outlet pipe 5 to uniformly heat the room, ensuring uniform heating and improving human comfort. This device solves the problem of existing heating systems that directly heat air through a fireplace, generating excessively high temperatures in the room, causing localized excessively high temperatures and causing discomfort to people. This device provides a temperature control device for a heating system that can regulate the temperature of the hot air generated by a fireplace, ensuring uniform heating and improving human comfort.

[0039] In this embodiment, the air outlet device 3 further includes a temperature sensor, which detects the temperature of the mixture of hot air and cold air in the air outlet device 3.
