Description

Technical Field

[0001] The invention relates to the technical field of water heaters, and in particular to an air source water heater. Background Art

[0002] The current air source water heater, also known as "air source heat pump water heater", "air energy water heater" absorbs low-temperature heat in the air, vaporizes it through fluorine medium, then compresses it through a compressor to increase the pressure and temperature, and then converts it into water heating through a heat exchanger. The compressed high-temperature heat energy is used to heat the water temperature. In the prior art, hot water is often heated and stored through a water tank. Traditional air source water heaters only have one water storage chamber. After the water in the water storage chamber is used up, it needs to be heated for more than an hour before it can be used again, and after the heating is completed, the water in the water storage chamber needs to be continuously insulated.

[0003] After searching, Chinese patent No. CN112066549A discloses an energy-saving air source water heater, including a water heater, wherein a heating chamber and an insulation chamber are provided in the water heater, a partition plate is fixed between the heating chamber and the insulation chamber, the upper end of the heating chamber is connected with a water inlet pipe, the bottom of the insulation chamber is connected with a water outlet pipe, a connecting pipe passes through the dividing plate, an electronic valve No. 1 is installed on the water inlet pipe, an electronic valve No. 2 is installed on the connecting pipe, a temperature monitor is installed on the top surface of the heating chamber, a water pressure detector No. 1 is installed on the bottom of the heating chamber, and a water pressure detector No. 2 is installed on the bottom of the dividing plate surface.

[0004] Although the above-mentioned air source water heater can add water to the heating chamber in time through the mutual cooperation of the electronic valve, the water pressure detector and the PLC controller to ensure that there is always hot water reserve in the insulation chamber; in addition, a temperature monitor is also provided to disconnect the power supply and stop heating after the heating temperature reaches the set temperature to achieve the effect of energy saving and heat preservation, there are still the following shortcomings:

[0005] 1. After the heated hot water is input into the heat preservation chamber, an additional heating mechanism needs to be provided to keep the hot water in the heat preservation chamber warm, which consumes a lot of energy.

[0006] 2. The surface area of ​​the partition of the water tank is large, and the contact area between the insulation chamber and the heating chamber is also large. When cold water is input into the heating chamber, the hot water in the insulation chamber will exchange a lot of heat to the heating chamber, and the insulation effect is poor.

[0007] To this end, an air source water heater is proposed. Summary of the invention

[0008] The object of the present invention is to provide an air source water heater, which solves the problems raised in the above background technology by arranging two upper and lower boxes, with the top box being used for heating and the bottom box being used for heat preservation.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0010] An air source water heater comprises a water heater body, a heat preservation layer is arranged inside the water heater body, a water tank is arranged inside the water heater body, a partition is fixedly installed inside the water tank, the partition divides the water tank into a top box and a bottom box of the same volume, heat exchange pipes are evenly wound on the outer wall of the top box, a compressor and a heat exchanger are connected to the two ends of the top box respectively, a water outlet pipe is connected to the outer wall of the bottom end of the bottom box, a water inlet pipe is connected to the outer wall of the top end of the top box, a motor is installed on the top wall of the water heater body, and the output of the motor A motor shaft is installed at the end, a rotating rod is fixedly connected to the bottom end of the motor shaft, and the bottom end of the rotating rod extends into the top box, a plurality of stirring blades are evenly installed on the outer wall of the rotating rod, a heat preservation mechanism is provided on the outer wall of the bottom box, a pressurizing assembly is connected to the top end of the top box, and the pressurizing assembly is used to quickly press the hot water in the top box into the bottom box, a drain trough is provided in the partition, and a control valve cooperating with the drain trough is installed in the partition, and the control valve opens when the water in the top box is heated to a specified temperature and the water in the bottom box reaches the lowest water level.

[0011] The air-energy water heater absorbs the low-temperature heat in the air, gasifies it through the fluorine medium, then compresses it through the compressor, pressurizes and heats it, and then converts it into water heating through the heat exchanger. The compressed high-temperature heat energy is used to heat the water temperature. The insulation mechanism is to insulate the water in the bottom box through the insulation pipe wound on the bottom box, and then transmit it to the heat exchange pipe connected to the insulation pipe to heat the water in the top box. In order to improve the heating efficiency of the water, a motor and a rotating rod and stirring fan blades connected thereto are installed on the top wall of the water heater body to stir the water in the top box. After heating, the water is heated by the pressurizing group Parts are used to accelerate the flow of heated water from the top box to the bottom box. In order to ensure the normal operation of the pressurizing component, a positioning mechanism needs to be opened on the rotating rod. The positioning mechanism can fix the stirring rotating rod to the position corresponding to the pressure plate to ensure the smooth implementation of the pressurizing component. After the water in the top box is heated, the control valve located in the partition detects that the specified temperature has been reached, and the sealing gate plate pushes into the movable groove, and the heated water can flow to the connecting valve. The connecting valve is controlled by the control component. When it is lower than the specified water level, the circuit is connected, the solenoid valve opens, and the heated hot water can flow from the top box to the bottom box for insulation.

[0012] Preferably, the heat-insulating mechanism comprises a heat-insulating tube evenly wound around the outer wall of the bottom box, and the heat-insulating tube is connected between the compressor and the heat exchange tube.

[0013] After the compressor compresses the air, it increases the pressure and temperature, and the water in the bottom box is insulated by the insulation pipe wound around the bottom box, and then transmitted to the heat exchange pipe connected to the insulation pipe. There is no need to set up additional insulation equipment to insulate the hot water in the bottom box, thereby reducing the manufacturing and use costs of the insulation mechanism and the air source water heater.

[0014] Preferably, the pressurizing assembly includes two cylinders symmetrically installed on the top wall of the top box, and a pressure plate is fixedly installed on the output ends of the two cylinders, and the pressure plate is located inside the top box. A through hole matching the rotating rod and the stirring blades is opened on the pressure plate, and a positioning assembly is connected to the rotating rod to fix the rotating rod and the stirring blades to the bottom end of the through hole.

[0015] The two cylinders installed on the top box press the pressure plate downward to accelerate the flow of hot water from the top box to the bottom box. In order to ensure the normal operation of the pressurizing component, it is necessary to open a positioning mechanism on the rotating rod. Under the premise of ensuring that the through holes on the pressure plate can smoothly pass through the rotating rod and the stirring fan blades, when the water temperature in the top box reaches the set temperature and the lower valve is opened, the hot water is accelerated to be pressed from the top box into the bottom box.

[0016] Preferably, the positioning assembly includes a plurality of slots evenly arranged on the outer wall of the top end of the rotating rod, an electromagnet is fixedly mounted on the inner wall of the top end of the water heater body, and the electromagnet is located on one side of the rotating rod and the slot, an iron block is elastically connected to the side of the electromagnet close to the slot, a block that cooperates with the slot is fixedly mounted on the outer wall of the iron block close to the slot, and the electromagnet is electrically connected to the motor.

[0017] In order to ensure that the pressurizing assembly can operate normally, it is necessary to provide a positioning mechanism on the rotating rod, and a card slot is installed on one side of the rotating rod. When the motor is powered off, the electromagnet electrically connected to the motor is powered off and loses its magnetic force, and the spring begins to recover and pushes the card block to move outward. The card block fits tightly against the outer wall of the rotating rod, and the card block cannot be positioned. Since six card slots are provided on the rotating rod, when the card slot on the rotating rod moves to the card block position, the card block is pushed into the card slot under the action of the spring force to fix the rotating rod, preventing the rotating rod from rotating and stopping it at a position corresponding to the stirring blades, thereby ensuring that the pressurizing assembly can pass through the rotating rod and the stirring blades smoothly. When the motor is powered on, the card block attracts the electromagnet, and the motor starts to drive the motor shaft to rotate, thereby ensuring that the pressurizing mechanism can stop moving at a fixed position, allowing it to work normally.

[0018] Preferably, the control valve includes a cylinder body fixedly mounted on the top wall of the partition, a piston movably mounted inside the cylinder body, a metal memory alloy wire is connected between the piston and the inner wall at one end of the cylinder body, the cylinder body is filled with a heat-conducting liquid that cooperates with the metal memory alloy wire, a push rod is fixedly mounted on the end of the piston away from the cylinder body, and the push rod passes through the cylinder body, and a sealing gate plate for sealing the top of a drain trough is fixedly connected to the end of the push rod away from the cylinder body, a movable groove that cooperates with the sealing gate plate is provided on the inner wall of the drain trough, a solenoid valve is connected to the bottom end of the drain trough, a control component is connected to the solenoid valve, and when the water in the bottom box is at the lowest water level line, the control component controls the solenoid valve to open.

[0019] After the water in the top box is heated, the heat-conducting liquid in the cylinder body that is tightly fitted with the inner wall of the partition absorbs heat and heats up under the action of heat transfer. The cylinder body is filled with heat-conducting liquid, and the metal memory alloy wire is immersed in the heat-conducting liquid. The metal memory alloy wire is in a bent state at room temperature, and its two ends are fixedly connected to the cylinder body and the piston respectively. When the metal memory alloy wire is heated, it becomes a straight metal memory alloy wire, which pushes the push rod to push the sealing gate into the movable groove, ensuring that the sealing gate is opened only when the temperature of the top box reaches a certain temperature, thereby realizing the control of the valve switch by temperature and improving the intelligence of the water heater control.

[0020] Preferably, the control component includes a connecting groove provided on the inner side wall at the bottom end of the water heater body, and the connecting groove is connected with the outer side wall at the bottom end of the bottom box, a guide rod is fixedly installed inside the connecting groove, a floating plate is sleeved on the guide rod, a permanent magnet is fixedly connected to the outer side wall of the floating plate away from the end of the bottom box, an installation groove is provided on the inner side wall at the bottom end of the water heater body, and the installation groove is located on one side of the bottom end of the connecting groove, a first joint is elastically connected on the inner side wall of the installation groove away from the end of the connecting groove, a second joint that cooperates with the first joint is installed on the inner side wall of the installation groove close to the end of the connecting groove, and the first joint and the second joint are electrically connected to the solenoid valve together.

[0021] The connecting valve is controlled by the water level in the bottom tank. When it is lower than the specified water level, the water level in the connecting groove on one side of the bottom tank drops, and the floating plate drops along with the water level. When it drops to the same position as the first joint, the permanent magnet on one side of the floating plate attracts the first joint in the mounting groove to contact the second joint to connect the circuit, thereby ensuring that after the water in the bottom tank is used up and the water temperature in the top tank is heated to the set temperature, the water in the top tank can quickly flow into the bottom tank under the operation of the pressurizing component.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. After the compressor compresses the air, it increases the pressure and temperature. The water in the bottom box is insulated by the insulation pipe wound around the bottom box, and then transmitted to the heat exchange pipe connected to the insulation pipe. There is no need to set up additional insulation equipment to insulate the hot water in the bottom box, thereby reducing the manufacturing and use costs of the insulation mechanism and the air source water heater.

[0024] 2. In order to ensure the normal operation of the pressurizing component, a positioning mechanism needs to be provided on the rotating rod. A card slot is installed on one side of the rotating rod. When the motor is powered off, the electromagnet electrically connected to the motor is powered off and loses its magnetic force. The spring pops out the iron block, and the card block on the iron block enters the card slot, fixing the rotating rod. The card block pops out to prevent the rotating rod from rotating and stops it at a position corresponding to the stirring blades, thereby ensuring that the pressurizing component can pass through the rotating rod and the stirring blades smoothly. When the motor is powered on, the card block attracts the electromagnet, and the motor starts to drive the motor shaft to rotate, thereby ensuring that the pressurizing mechanism can stop moving at a fixed position, allowing the pressure plate to work normally and enhancing the stability of the water heater.

[0025] 3. The connecting valve is controlled by the water level of the bottom box. When it is lower than the specified water level, the water level in the connecting groove on one side of the bottom box drops, and the floating plate drops along with the water level. When it drops to the same position as the first joint, the permanent magnet on one side of the floating plate attracts the first joint in the mounting groove to contact the second joint to connect the circuit, thereby ensuring that after the water in the bottom box is used up and the water temperature in the top box is heated to the set temperature, the water in the top box quickly flows to the bottom box under the operation of the pressurizing component.

A drain trough is provided in the partition 2, and a control valve that cooperates with the drain trough is installed in the partition 2. The control valve opens when the water in the top box is heated to a specified temperature and the water in the bottom box reaches the lowest water level.

[0040] The air energy water heater absorbs the low temperature heat in the air, gasifies it through the fluorine medium, and then compresses it through the compressor to increase the pressure and temperature, and then converts it into water heating through the heat exchanger. The compressed high temperature heat energy is used to heat the water temperature. The insulation mechanism is to insulate the water in the bottom box through the insulation pipe 30 wound on the bottom box, and then transmit it to the heat exchange pipe 29 connected to the insulation pipe 30 to heat the water in the top box. In order to improve the heating efficiency of the water, a motor 5 and a rotating rod 7 and a stirring fan blade 8 connected thereto are installed on the top wall of the water heater body to stir the water in the top box. After heating, the water is heated by the pressurizing group The components are used to accelerate the flow of heated water from the top box to the bottom box. In order to ensure the normal operation of the pressurizing component, a positioning mechanism needs to be provided on the rotating rod 7. The positioning mechanism can fix the stirring rotating rod 7 to the position corresponding to the pressure plate 10 to ensure the smooth implementation of the pressurizing component. After the water in the top box is heated, when the control valve located in the partition 2 detects that the specified temperature has been reached, the sealing gate plate 20 pushes into the movable groove 21, and the heated water can flow to the connecting valve. The connecting valve is controlled by the control component. When it is lower than the specified water level, the circuit is connected, the solenoid valve opens, and the heated hot water can flow from the top box to the bottom box for insulation.

[0041] As an embodiment of the present invention, refer to Figure 1 The insulation mechanism includes an insulation pipe 30 evenly wound on the outer wall of the bottom box, and the insulation pipe 30 is connected between the compressor and the heat exchange pipe 29.

[0042] After the compressor compresses the air, it increases the pressure and temperature, and the water in the bottom box is insulated by the insulation pipe 30 wound around the bottom box, and then transmitted to the heat exchange pipe 29 connected to the insulation pipe 30. There is no need to set up additional insulation equipment to insulate the hot water in the bottom box, thereby reducing the manufacturing and use costs of the insulation mechanism and the air source water heater.

[0043] As an embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The pressurizing component includes two cylinders 9 symmetrically installed on the top wall of the top box, and a pressure plate 10 is fixedly installed on the output ends of the two cylinders 9, and the pressure plate 10 is located in the top box. A through hole matching the rotating rod 7 and the stirring blade 8 is opened on the pressure plate 10, and the rotating rod 7 is connected to a positioning component that fixes the rotating rod 7 and the stirring blade 8 to the bottom end of the through hole.

[0044] The two cylinders 9 installed on the top box press the pressure plate 10 downward to accelerate the flow of hot water from the top box to the bottom box. In order to ensure the normal operation of the pressurizing component, it is necessary to open a positioning mechanism on the rotating rod 7. On the premise that the through hole on the pressure plate 10 can smoothly pass through the rotating rod 7 and the stirring fan blade 8, when the water temperature in the top box reaches the set temperature and the lower end valve is opened, the hot water is accelerated to be pressed from the top box to the bottom box, thereby improving the efficiency of hot water transmission of the water heater.

[0045] As an embodiment of the present invention, refer to Figure 1 , Figure 6 The positioning assembly includes a plurality of slots 11 evenly arranged on the outer side wall of the top end of the rotating rod 7, an electromagnet 12 is fixedly installed on the inner side wall of the top end of the water heater body, and the electromagnet 12 is located on one side of the rotating rod 7 and the slot 11, an iron block 13 is elastically connected to the side of the electromagnet 12 close to the slot 11, and a block 14 that cooperates with the slot 11 is fixedly installed on the outer side wall of the iron block 13 close to the slot 11, and the electromagnet 12 is electrically connected to the motor 5.

[0046] When the motor 5 is powered on, the electromagnet 12 is attracted by the block 14, and the motor 5 starts to drive the motor shaft 6 to rotate, thereby ensuring that the pressure mechanism can stop moving at a fixed position and work normally.

[0047] As an embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 8 The control valve includes a cylinder body 15 fixedly mounted on the top wall of the partition 2, a piston 16 movably mounted inside the cylinder body 15, a metal memory alloy wire 17 connected between the piston 16 and the inner side wall at one end of the cylinder body 15, the cylinder body 15 is filled with a heat transfer fluid 18 that cooperates with the metal memory alloy wire 17, a push rod 19 is fixedly mounted on the end of the piston 16 away from the cylinder body 15, and the push rod 19 runs through the cylinder body 15, and a sealing gate plate 20 for sealing the top of the drain groove is fixedly connected to the end of the push rod 19 away from the cylinder body 15, a movable groove 21 that cooperates with the sealing gate plate 20 is opened on the inner side wall of the drain groove, a solenoid valve is connected to the bottom end of the drain groove, and a control component is connected to the solenoid valve. When the water in the bottom box is at the lowest water level line, the control component controls the solenoid valve to open.

[0048] After the water in the top box is heated, the heat-conducting liquid 18 in the cylinder body 15 that is tightly fitted with the inner wall of the partition 2 absorbs heat and heats up under the action of heat transfer. The cylinder body 15 is filled with the heat-conducting liquid 18, and the metal memory alloy wire 17 is immersed in the heat-conducting liquid 18. The metal memory alloy wire 17 is in a bent state at room temperature, and its two ends are respectively fixedly connected to the cylinder body 15 and the piston 16. When the metal memory alloy wire 17 is heated, it becomes a straight metal memory alloy wire 17, which pushes the push rod 19 to push the sealing gate 20 into the movable groove 21, ensuring that the sealing gate 20 is opened only when the temperature of the top box reaches a certain temperature, thereby realizing the control of the valve switch by temperature, and improving the intelligence of the water heater control.

[0049] As an embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 8The control component includes a connecting groove 22 provided on the inner side wall at the bottom end of the water heater body, and the connecting groove 22 is connected to the outer side wall at the bottom end of the bottom box, a guide rod 23 is fixedly installed inside the connecting groove 22, a floating plate 24 is sleeved on the guide rod 23, and a permanent magnet 25 is fixedly connected to the outer side wall of the floating plate 24 away from the end of the bottom box, a mounting groove 26 is provided on the inner side wall at the bottom end of the water heater body, and the mounting groove 26 is located on one side of the bottom end of the connecting groove 22, a first joint 27 is elastically connected to the inner side wall of the mounting groove 26 away from the end of the connecting groove 22, a second joint 28 that cooperates with the first joint 27 is installed on the inner side wall of the mounting groove 26 close to the end of the connecting groove 22, and the first joint 27 and the second joint 28 are electrically connected to the solenoid valve together.

[0050] The connecting valve is controlled by the water level in the bottom tank. When it is lower than the specified water level, the water level in the connecting groove on one side of the bottom tank drops, and the float plate 24 drops along with the water level. When it drops to the same position as the first joint 27, the permanent magnet 25 on one side of the float plate 24 attracts the first joint 27 in the mounting groove 26 to contact the second joint 28 to connect the circuit. This ensures that after the water in the bottom tank is used up and the water temperature in the top tank is heated to the set temperature, the water in the top tank quickly flows to the bottom tank under the operation of the pressurizing component, thereby improving the automation of the control of the water heater body.

[0051] Working principle: The air-source water heater absorbs low-temperature heat from the air, vaporizes it through the fluorine medium, and then compresses it through a compressor to increase the pressure and temperature, and then converts it into water heating through a heat exchanger. The compressed high-temperature heat energy is used to heat the water temperature. The insulation mechanism insulates the water in the bottom box through the insulation pipe 30 wound around the bottom box, and then transmits it to the heat exchange pipe 29 connected to the insulation pipe 30 to heat the water in the top box. The compressor compresses the air and increases the pressure and temperature, and insulates the water in the bottom box through the insulation pipe 30 wound around the bottom box, and then transmits it to the heat exchange pipe 29 connected to the insulation pipe 30. There is no need to set up additional insulation equipment to insulate the hot water in the bottom box, thereby reducing the manufacturing and use costs of the insulation mechanism and the air source water heater. In order to improve the heating efficiency of water, a motor 5 and a rotating rod 7 and a stirring blade 8 connected thereto are installed on the top wall of the water heater body to stir the water in the top box. After heating, the pressurizing component is used to accelerate the heated water to flow from the top box to the bottom box. In order to ensure that the pressurizing component can operate normally, a positioning mechanism needs to be provided on the rotating rod 7. The two cylinders 9 installed on the top box press down the pressure plate 10 to accelerate the hot water to flow from the top box to the bottom box. In order to ensure that the pressurizing component can operate normally, a positioning mechanism needs to be provided on the rotating rod 7. On the premise that the through hole on the pressure plate 10 can smoothly pass through the rotating rod 7 and the stirring blade 8, when the water temperature in the top box reaches the set temperature and the lower end valve is opened, the hot water is accelerated to be pressed from the top box into the bottom box. The positioning mechanism can fix the stirring rotating rod 7 to the position corresponding to the pressure plate 10 to ensure the smooth implementation of the pressurizing component. After the water in the top box is heated, the control valve located in the partition 2 detects that it has reached the specified temperature, and the sealing gate The plate 20 pushes into the movable groove 21. After the water in the top box is heated, the temperature of the heat-conducting liquid 18 in the cylinder 15 in the partition 2 rises, and the metal memory alloy wire 17 expands due to the heat and pushes the push rod 19 to push the sealing gate plate 20 into the movable groove 21, so that the temperature rise of the top box can be sensitively sensed, and the sealing gate plate 20 is opened, and the heated water can flow to the connecting valve. The connecting valve is controlled by the control component. When it is lower than the specified water level, the circuit is connected, the solenoid valve is opened, and the connecting valve is controlled by the water level of the bottom box. When it is lower than the specified water level, the water level in the connecting groove on one side of the bottom box drops, and the floating plate 24 drops with the water level. When it drops to the same position as the first joint 27, the permanent magnet 25 on one side of the floating plate 24 attracts the first joint 27 in the installation groove 26 to contact the second joint 28 to connect the circuit, so that it can be ensured that after the water in the bottom box is used up and the water temperature in the top box is heated to the set temperature, the water in the top box quickly flows to the bottom box under the operation of the pressurizing component.

In order to ensure that the pressurizing component can operate normally, a positioning mechanism needs to be provided on the rotating rod (7). When the motor (5) is powered off, the electromagnet (12) electrically connected to the motor (5) loses power and loses its magnetic force. The spring begins to recover and pushes the card block (14) to move outward. The card block (14) is tightly fitted with the outer side wall of the rotating rod (7). The card block (14) cannot be positioned. Since a plurality of card slots (11) are provided on the rotating rod (7), when the card slots (11) on the rotating rod (7) move to the card block (1 4), the block (14) is pushed into the card slot (11) under the action of the spring force so that the rotating rod (7) is fixed, the rotating rod (7) is prevented from rotating and stopped at a position corresponding to the stirring blade (8), thereby ensuring that the pressurizing component can smoothly pass through the rotating rod (7) and the stirring blade (8); on the premise that the through hole on the pressing plate (10) can smoothly pass through the rotating rod (7) and the stirring blade (8), when the water temperature in the top box reaches the set temperature and after the lower end valve is opened, the hot water in the top box is quickly pressed into the bottom box through the pressurizing component; the water in the top box is heated up Afterwards, the heat transfer fluid (18) in the cylinder (15) which is in close contact with the inner wall of the partition (2) absorbs heat and rises in temperature under the action of heat transfer. The cylinder (15) is filled with the heat transfer fluid (18), and the metal memory alloy wire (17) is immersed in the heat transfer fluid (18). The metal memory alloy wire (17) is in a bent state at room temperature, and its two ends are respectively fixedly connected to the cylinder (15) and the piston (16). When the metal memory alloy wire (17) is heated, it becomes a straight metal memory alloy wire (17) and pushes the push rod (19) to push the sealing gate plate (20) into the movable groove (21). The sealing gate (20) is opened only when the temperature of the top box reaches the set temperature; when the water level in the bottom box is lower than the specified water level, the water level in the connecting groove on one side of the bottom box drops, and the floating plate (24) drops along with the water level. When it drops to the same position as the first joint (27), the permanent magnet (25) on one side of the floating plate (24) attracts the first joint (27) in the mounting groove (26) to contact the second joint (28) so that the circuit is connected, thereby ensuring that after the water in the bottom box is used up and the water temperature in the top box is heated to the set temperature, the water in the top box quickly flows into the bottom box under the operation of the pressurizing component.
