Description

Technical Field

[0001] The invention relates to the field of electrical technology, in particular to an automatic control device for indoor floor heating. Background Art

[0002] Geothermal heating is a new heating method. Geothermal heating uses electric water boilers, gas water boilers or oil water boilers and other thermal energy equipment to heat water first, and then uses a hot water circulation pump to force the hot water in the boiler and the coil under the floor to indirectly heat the floor and achieve radiant heating.

[0003] The design and installation of geothermal heating requires a water supply tank. The water supply tank is mainly used to automatically transport the water stored in the water supply tank to the heater through the water pipe for water supply replenishment when the water pump stops working; to avoid evaporation and side leakage during the operation of the entire indoor geothermal automatic control equipment, resulting in insufficient circulating water;

[0004] At present, the automatic adjustment and control of the water volume inside the water replenishment tank is generally composed of a float, a weight block and a water pump electrically connected to the float through a wire; a float block and a conductive contact piece are arranged inside the float, and the contact state of the float block and the conductive contact piece can be automatically adjusted by the different buoyancy generated by the different water volumes inside the water replenishment tank on the float and the weight block, and then the running state of the water pump is controlled by the corresponding electrical signal to realize the water replenishment operation inside the water replenishment tank;

[0005] However, the problems and defects of this automatic water adjustment method inside the water supply tank are also obvious. For example, for the inside of the float, in order to prevent water from seeping in, causing moisture to accelerate oxidation corrosion between the float block and the conductive contact piece, shortening the service life, it is necessary to ensure the sealing of the float while also ensuring the sealing of the contact position between the float and the wire, and the installation waterproof requirements are high; at the same time, it is also necessary to set up a wire to be electrically connected to the water pump to realize the output of the electrical signal, so the automatic control of the water supply tank also requires energy consumption;

[0006] In view of the problems in the above background technology, the present invention aims to provide an automatic control device for indoor floor heating. Summary of the invention

[0007] The object of the present invention is to provide an automatic control device for indoor floor heating to solve the problems raised in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] An indoor floor heating automation control device, the indoor floor heating automation control device comprising:

[0010] A water storage tank, a heater and a control cabinet, wherein one end of the water storage tank is connected to a water pipe; a water inlet valve is arranged inside the water storage tank, one end of the water inlet valve is connected to one end of the water pipe, a buoyancy component is movably installed at the other end of the water inlet valve, and a notch is opened at the lower end of the water inlet valve;

[0011] The lower end of the water storage tank is connected to a water pipe, and one end of the water pipe is connected to a heater; a one-way valve is installed on the water pipe; one end of the control cabinet is electrically connected to the heater through a wire, and a display panel is installed on the control cabinet; one end of the heater is respectively connected to a water inlet pipe and a drain pipe, a water pump is installed on the water inlet pipe, and an electric proportional valve and a temperature transmitter are respectively installed on the drain pipe.

[0012] As a further solution of the present invention: a heating chamber and a filter chamber are formed inside the heater respectively, the filter chamber is connected to the heating chamber, a heating resistance wire is arranged inside the heating chamber, and a filter is installed inside the filter chamber.

[0013] As a further solution of the present invention: a movable cavity is formed inside the water inlet valve, and the movable cavity formed inside the water inlet valve is in the shape of a cross; the buoyancy assembly includes a piston, a movable rod, a rotating rod and a floating ball, and the number of the pistons is two, and the two pistons are symmetrically distributed and movably installed inside the movable cavity, and the two pistons are connected by a movable rod; a crank is installed on the part of one end of the movable rod after passing through the inner wall of the water inlet valve, and the lower end of the crank is rotatably installed on the water inlet valve; one end of the rotating rod is hinged and movably installed with the lower end of the crank, and a floating ball is installed on the other end of the rotating rod.

[0014] As a further solution of the present invention: a stopper is further provided at one side of the upper end of the rotating rod, and an L shape is formed between the stopper and the rotating rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Compared with the current automatic water replenishment method of the water replenishment tank for geothermal heating, the indoor geothermal automatic control device has the following advantages:

[0017] First, a water inlet valve is provided inside the water storage tank, one end of the water inlet valve is connected to one end of the tap water pipe, a buoyancy component is movably installed on the other end of the water inlet valve, and a notch is provided at the lower end of the water inlet valve; when the water shortage inside the water storage tank reaches a certain volume, so that the buoyancy generated by the water cannot exert enough driving force on the buoyancy component, the buoyancy component is used to open the water inlet valve, so that the tap water transported by the tap water pipe automatically enters the water storage tank through the notch provided at the lower end of the water inlet valve for replenishment; when the water source inside the water storage tank accumulates to a certain volume and exerts a sufficiently large buoyancy on the buoyancy component, the operation of the buoyancy component can cause blockage inside the water inlet valve, so as to prevent the water flow transported by the tap water pipe from continuing to be deposited inside the water storage tank; therefore, the water volume range inside the water storage tank can be always maintained dynamically;

[0018] The buoyancy assembly provided at the same time includes a piston, a movable rod, a rotating rod and a float. Through the cooperation of the float and the rotating rod, the volume of tap water entering the water tank can be automatically controlled within a relatively balanced and stable fluctuation range. There is no need to install other control electronic components such as water pumps, wires, floats and conductive sheets, which not only reduces the energy required for the water tank to maintain a dynamic balance of the water source, but also enables automatic control.

DETAILED DESCRIPTION

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Example

[0026] See also Figure 1 , Figure 2 and Figure 3 , an indoor geothermal automation control device provided in an embodiment of the present invention, the indoor geothermal automation control device comprising:

[0027] A water storage tank 2, a heater 5 and a control cabinet 8, wherein one end of the water storage tank 2 is connected to a water pipe 1, and the connected water pipe 1 is used to add tap water to the water storage tank 2; a water inlet valve 15 is arranged inside the water storage tank 2, one end of the water inlet valve 15 is connected to one end of the water pipe 1, and a buoyancy component is movably installed at the other end of the water inlet valve 15, and a notch is provided at the lower end of the water inlet valve 15; when the water shortage inside the water storage tank 2 reaches a certain volume, so that the buoyancy generated by the water cannot cause enough driving force to the buoyancy component, the buoyancy component is arranged The component is used to open the water inlet valve 15, so that the tap water transported by the water pipe 1 automatically enters the water storage tank 2 through the gap opened at the lower end of the water inlet valve 15 for replenishment; when the water source inside the water storage tank 2 accumulates to a certain volume and creates a sufficiently large buoyancy on the buoyancy component, the operation of the buoyancy component can cause blockage inside the water inlet valve 15 to prevent the water flow transported by the water pipe 1 from continuing to settle inside the water storage tank 2; therefore, the water volume range inside the water storage tank 2 can be dynamically maintained at all times without the need to set up any control electronic devices;

[0028] The lower end of the water storage tank 2 is connected to the water pipe 3, and one end of the water pipe 3 is connected to the heater 5; a one-way valve 4 is installed on the water pipe 3; one end of the control cabinet 8 is electrically connected to the heater 5 through a wire, and a display panel 7 is installed on the control cabinet 8; one end of the heater 5 is respectively connected to the water inlet pipe 10 and the drain pipe 14, a water pump 11 is installed on the water inlet pipe 10, and an electric proportional valve 12 and a temperature transmitter 13 are respectively installed on the drain pipe 14;

[0029] In the embodiment of the present invention, when the indoor floor heating automation control device is used, the operator first controls the control cabinet 8 to control the entire indoor floor heating automation control device to operate normally through the operation display panel 7;

[0030] For example, the water pump 11 is started, and the water pump 11 is operated to transport the water source through the water inlet pipe 10 to the inside of the heater 5 for filtration and heating, and then the water source is discharged from the drain pipe 14 to the inside of the geothermal pipe for heat exchange with the indoor floor, thereby heating the indoor floor; the electric proportional valve 12 installed on the drain pipe 14 is used to control the flow rate of the heat source discharge, and the temperature transmitter 13 installed on the drain pipe 14 is used to adjust the temperature of the heat source discharged from the drain pipe 14 by adjusting the electric proportional valve 12, so as to adjust the flow rate of the heat source discharge;

[0031] At the same time, when the water pump 11 stops operating, the water source stored in the water storage tank 2 is automatically transported to the heater 5 through the water delivery pipe 3 for water replenishment, thereby preventing evaporation and side leakage during the operation of the entire indoor geothermal automation control device, and preventing insufficient circulating water. The one-way valve 4 installed on the water delivery pipe 3 can ensure that the water source stored in the water storage tank 2 flows unidirectionally to the heater 5 without backflow.

[0032] See also Figure 1 In one embodiment of the present invention, a heating chamber and a filter chamber are formed inside the heater 5, the filter chamber is connected to the heating chamber, a heating resistor wire 6 is provided inside the heating chamber, and a filter 9 is installed inside the filter chamber;

[0033] After the water source enters the heater 5, the heating resistor 6 is connected to the power supply to generate resistance heat, which is used to heat the water source entering the heater 5; and the filter 9 can filter and intercept impurities in the incoming water source to prevent the impurities contained in the water from being attached to the inner wall of the geothermal pipe in the later stage, affecting the heat source flow rate and heat exchange efficiency of the geothermal pipe;

[0034] See also Figure 2 and Figure 3 In one embodiment of the present invention, an active cavity 22 is formed inside the water inlet valve 15, and the active cavity 22 formed inside the water inlet valve 15 is in the shape of a cross; the buoyancy assembly includes a piston 21, a movable rod 16, a rotating rod 19 and a floating ball 20, and the number of the pistons 21 is two, and the two pistons 21 are symmetrically distributed and movably installed inside the active cavity 22, and the two pistons 21 are connected by the movable rod 16; a crank 17 is installed on the part of the movable rod 16 that passes through the inner wall of the water inlet valve 15 at one end, and the lower end of the crank 17 is rotatably installed on the water inlet valve 15; one end of the rotating rod 19 is hinged and movably installed with the lower end of the crank 17, and the other end of the rotating rod 19 is installed with a floating ball 20;

[0035] In the embodiment of the present invention, for example, when the volume of water source stored in the water storage tank 2 is small, the buoyancy generated by the water source is smaller than the gravity caused by the float 20; under the action of the gravity of the float 20, the rotating rod 19 is pushed to rotate, and when the rotating rod 19 rotates, the movable rod 16 is pushed to slide horizontally through the crank 17; and when the movable rod 16 slides toward the outside of the water inlet valve 15, the piston 21 is pulled to slide inside the movable chamber 22, causing a gap to appear at the position where the water pipe 1 is connected to the water inlet valve 15, so that the tap water transported by the water pipe 1 enters the movable chamber 22 opened in the water inlet valve 15 and then flows out through the gap opened at the bottom end of the movable chamber 22 to enter the water storage tank 2;

[0036] When the volume of water entering the water storage tank 2 gradually increases, the buoyancy of the float ball 20 is generated, and when the generated buoyancy is getting larger and larger, the float ball 20 is pushed to be lifted. During the lifting process of the float ball 20, the rotating rod 19 is pushed to rotate. During the rotation process of the rotating rod 19, the movable rod 16 is pushed to slide into the water inlet valve 15, so that the piston 21 installed on the movable rod 16 blocks the position where the tap water pipe 1 is connected to the movable chamber 22, and the water source inside the water storage tank 2 is completed.

[0037] By cooperating with the floating ball 20 and the rotating rod 19, the volume of tap water entering the water storage tank 2 can be automatically controlled within a relatively balanced and stable fluctuation range without the need to install other control electronic components such as water pumps, wires, floating balls, and conductive sheets, which not only reduces the energy required for the water storage tank 2 to maintain a dynamic balance of water sources, but also enables automatic control.

[0038] In the embodiment of the present invention, a stopper 18 is further provided on one side of the upper end of the rotating rod 19, and an L shape is formed between the stopper 18 and the rotating rod 19;

[0039] In the embodiment of the present invention, the angle of the rotating rod 19 is limited by the stop rod 18, so as to prevent the floating ball 20 from pushing the rotating rod 19 to rotate due to the buoyancy, causing the rotating rod 19 to swing in two directions, thereby failing to automatically control the opening and closing of the water source of the water inlet valve 15;

[0040] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The above description is only a preferred embodiment of the present invention and is 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.
