Description

Technical Field

[0001] The present application relates to the technical field of water purification equipment, and in particular to an all-in-one water purification and heating machine. Background Art

[0002] With economic development and the improvement of living standards, consumers are paying more and more attention to healthy water use and drinking water, and their requirements for water use are getting higher and higher. As a water treatment device that can deeply filter and purify water according to water use requirements, water purifiers are recognized and favored by more and more consumers. At present, there is a water purifier and hot water all-in-one machine on the market, which enables consumers to receive both normal temperature purified water and hot water at the same time, thus gradually replacing the old water purifiers with only water purification function.

[0003] However, in areas with high altitudes and low air pressure, the boiling point of water will be lower. When using a heat and air purifier in these areas, the maximum temperature of the instant heating element of the heat and air purifier is generally 95°C, and the water is not really boiled. In addition, because there is a water outlet pipe from the instant heating element to the hot water outlet, the hot water will lose some heat when flowing in the water outlet pipe, causing the hot water temperature to drop, so that the temperature of the boiled water received by the user is often lower than 90°C, which cannot meet the user's demand for high-temperature boiled water. At present, some heat and air purifiers are connected to a flow regulating valve downstream of the instant heating element outlet. The opening of the flow regulating valve is used to pressurize the instant heating element to increase the boiling point of the water flow in the instant heating element, thereby increasing the water temperature of the instant heating element. However, when the flow regulating valve is damaged, it is easy to completely block the waterway, causing the instant heating element to be unable to drain normally, thereby causing pressure buildup or even bursting damage. Utility Model Content

[0004] The present application provides a heat and water purification integrated machine to solve the technical problems that the heat and water purification integrated machine used in areas with high altitude and low air pressure has difficulty in boiling hot water and discharges low hot water.

[0005] The technical solution adopted in this application is:

[0006] A water purification and heating integrated machine is provided with a hot water discharge port, comprising a filter unit, an instant heating body, a water circuit boosting device and a protection device, wherein the filter unit comprises a filter element and a boosting pump connected to the raw water inlet of the filter element, the water inlet of the instant heating body is connected to the clean water outlet of the filter element, the water outlet of the instant heating body is connected to the hot water discharge port, the water circuit boosting device is connected to the fluid path between the instant heating body and the hot water discharge port and can increase the water flow pressure upstream of the water circuit boosting device, and the protection device is arranged on the fluid path downstream of the clean water outlet of the filter element and can limit the water flow pressure upstream of the water circuit boosting device to below a first threshold value.

[0007] The heat and air purifier in this application also has the following additional technical features:

[0008] The water outlet of the instant heating body is connected to the protection device through a first water channel, and is connected to the hot water discharge port through a second water channel. When the water flow pressure in the second water channel reaches a second threshold, the water channel booster device is caused to open the second water channel. When the water flow pressure in the first water channel reaches the first threshold, the protection device is caused to open the first water channel. The first threshold is greater than the second threshold.

[0009] The first threshold is at least twice greater than the second threshold.

[0010] The protection device includes a first shell and a first movable part movably arranged in the first shell, the first shell having a first water inlet and a first water outlet, when the water flow pressure in the first water path is less than the first threshold value, the first movable part cuts off the connection between the first water inlet and the first water outlet, and when the water flow pressure in the first water path is greater than or equal to the first threshold value, the first movable part moves to connect the first water inlet and the first water outlet.

[0011] When the water flow pressure in the first water channel is less than the first threshold value, the first movable part is located at a first position blocking the first water inlet; when the water flow pressure in the first water channel is greater than or equal to the first threshold value, the first movable part moves toward the first water outlet to a second position and is confined to the second position so that the first water inlet and the first water outlet remain connected.

[0012] The protection device includes a temperature detection component and a flow detection component which are electrically connected to the control unit of the air conditioner and heat integrated machine respectively. The temperature detection component is arranged on the fluid path between the instant heating element and the water circuit boosting device, and the flow detection component is arranged on the fluid path between the filter element and the instant heating element. The temperature detection component and the flow detection component synchronously detect the water flow state upstream of the water circuit boosting device and control the water flow state upstream of the water circuit boosting device through the control unit.

[0013] The water channel boosting device includes a second shell and a second movable part movably arranged in the second shell, the second shell has a second water inlet and a second water outlet, an elastic part is arranged between the second movable part and the second shell, the second movable part can overcome the elastic force of the elastic part under the action of upstream water flow pressure and move to a third position that connects the second water inlet with the second water outlet, and can be reset to a fourth position that blocks the second water inlet under the action of the elastic force of the elastic part.

[0014] The water channel booster device is provided with a Tesla valve channel, and the Tesla valve channel is connected to the water outlet of the instant heating body in reverse direction and connected to the hot water discharge port in forward direction.

[0015] It also includes a water vapor separation box provided with a water vapor separation chamber, the water vapor separation box is provided with an exhaust port, and the water channel pressurizing device, the exhaust port and the hot water discharge port are respectively connected to the water vapor separation chamber.

[0016] A normal temperature water outlet connected to the clean water outlet of the filter element is also provided, a first solenoid valve is provided on the fluid path between the filter element and the normal temperature water outlet, and a second solenoid valve and a water pump are provided on the fluid path between the filter element and the instant heating body.

[0017] Due to the adoption of the above technical solution, the technical effects achieved by this application are:

[0018] 1. The integrated heat and air purifier provided in the present application is connected with a water channel booster on the fluid path between the instant heating element and the hot water discharge port, and the water channel booster generates resistance to the upstream water flow by the water channel booster to increase the upstream water flow pressure. Therefore, the water flow pressure in the instant heating element will also increase to a certain extent, so that the pressure in the instant heating element is higher than the normal pressure, and the boiling point of the water flow in the instant heating element is also higher than the boiling point under normal pressure. The boiling point of water also increases with the increase of pressure. Therefore, when the instant heating element heats the water, the water temperature can be heated to not less than 100°C to make the hot water truly boil. Moreover, even if some heat is lost in the process of the boiling water flowing through the water outlet pipe to the hot water discharge port, the water will not be heated when it reaches the hot water discharge port. It can also ensure that the water temperature is above 95°C to meet the user's demand for high-temperature boiled water; in addition, the protection device arranged on the fluid path downstream of the purified water outlet of the filter element plays a role in water channel protection, which can limit the water flow pressure upstream of the water channel booster device to below the first threshold value. When the water channel booster device fails and completely blocks the water channel, the water flow pressure upstream of the water channel booster device continues to rise to the first threshold value. The protection device limits the water flow pressure upstream of the water channel booster device to below the first threshold value by relieving pressure, controlling the filter unit to stop water supply, etc., to prevent the occurrence of pressure holding phenomenon, which may cause the water channel structure such as the instant heating body to expand, burst and be damaged, thereby improving the safety of the integrated heat and water purification machine.

[0019] 2. As a preferred embodiment of the present application, the water outlet of the hot body is connected to the protection device and the hot water discharge port respectively through the first water channel and the second water channel. When the water channel booster device is in normal use, when the pressure of the hot water discharged by the hot body reaches the second threshold value, the water channel booster device connects the second water channel to allow the hot water to be discharged normally to the hot water discharge port. When the water channel booster device fails and completely blocks the second water channel, the water flow pressure of the hot body continues to increase until it increases to the first threshold value, prompting the protection device to connect the first water channel, so that the hot body releases pressure through the first water channel, and the pressure is reduced to normal pressure, thereby effectively protecting the water channel structure.

[0020] 3. As a preferred embodiment of the present application, by making the first threshold value at least twice greater than the second threshold value, on the basis of ensuring that the waterway is safe and in normal use when the water flow pressure is less than the first threshold value, the gap between the first threshold value and the second threshold value is increased as much as possible to ensure that the protective device is in a normally closed state during the normal operation of the waterway booster device.

[0021] 4. As a preferred embodiment of the present application, the protection device includes a first shell and a first movable part movably arranged in the first shell. When the water pressure in the first water circuit is less than a first threshold value, the first movable part cuts off the first water inlet and the first water outlet to cut off the first water circuit, so that the instant heating body can drain water normally to the hot water discharge outlet through the second water circuit. When the water pressure in the first water circuit is greater than or equal to the first threshold value, the first movable part connects the first water inlet and the first water outlet to connect the first water circuit, so that the instant heating body can relieve pressure through the first water circuit. The overall structure of the protection device is simple and easy to install. It is a non-electric structure and only needs to change its own state under the action of changes in water circuit pressure to cut off or connect the first water circuit, which helps to save costs.

[0022] 5. As a preferred embodiment of the present application, when the water flow pressure in the first water circuit is greater than or equal to the first threshold value, the first movable member moves toward the first water outlet to the second position and is confined to the second position so that the first water inlet and the first water outlet remain connected. In other words, after the protection device moves from the first position to the second position, it can no longer be reset from the second position to the first position, that is, the protection device is a non-self-resetting structure, so that when the water flow pressure in the first water circuit is greater than or equal to the first threshold value, the protection device opens and is in a normally open state, so that the pressure in the system quickly returns to normal pressure, effectively ensuring the safety of the entire system.

[0023] 6. As a preferred embodiment of the present application, the protection device is composed of a temperature detection element and a flow detection element. The temperature detection element and the flow detection element synchronously detect the water flow state upstream of the water circuit boosting device and control the water flow state upstream of the water circuit boosting device through the control unit. For example, when the temperature detection element detects that the water temperature continues to rise and exceeds the set value and the flow detection element detects that the water flow is still and not flowing, the control unit can control the system to stop supplying water to the instant heating body, and at the same time control the instant heating body to stop heating, thereby preventing the water pressure from exceeding the first threshold value, thereby effectively protecting the system safety.

[0024] 7. As a preferred embodiment of the present application, the water circuit booster device is composed of a second shell, a second movable part and an elastic part. The second movable part switches its position as the water pressure changes, so that the fluid path between the instant heating element and the hot water discharge port is connected or cut off, and is reset by the elastic part. The overall structure is simple, the installation is convenient and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In the present application, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0039] In the embodiment of the present application, a heat and air purifier is provided. For the convenience of explanation and understanding, the following contents provided in the present application are all explained on the basis of the illustrated product structure. Of course, it can be understood by those skilled in the art that the above structure is only used as a specific example and schematic description, and cannot constitute a specific limitation on the technical solution provided in the present application.

[0040] Reference Figures 1 to 6As shown, a water purification and heating integrated machine provided in the present application is provided with a hot water discharge port 11, including a filtering unit, an instant heating body 14, a water circuit boosting device 15 and a protective device 16, the filtering unit includes a filter element 12 and a boosting pump 13 connected to the raw water inlet of the filter element 12, the water inlet of the instant heating body 14 is connected to the clean water outlet of the filter element 12, the water outlet of the instant heating body 14 is connected to the hot water discharge port 11, the water circuit boosting device 15 is connected to the fluid path between the instant heating body 14 and the hot water discharge port 11 and can increase the water flow pressure upstream of the water circuit boosting device 15, the protective device 16 is arranged on the fluid path downstream of the clean water outlet of the filter element 12 and can limit the water flow pressure upstream of the water circuit boosting device 15 to below a first threshold.

[0041] In the integrated heat and water purification machine provided in the present application, a water channel booster 15 is connected to the fluid path between the instant heating body 14 and the hot water discharge port 11. The water channel booster 15 generates resistance to the upstream water flow to increase the upstream water flow pressure. Therefore, the water flow pressure in the instant heating body 14 will also increase to a certain extent, so that the pressure in the instant heating body 14 is higher than the normal pressure, and the boiling point of the water flow in the instant heating body 14 is also higher than the boiling point under normal pressure. The boiling point of water also increases with the increase in pressure. Therefore, when heating water, the instant heating body 14 can heat the water temperature to not less than 100°C to make the hot water truly boil. Moreover, even if some heat is lost in the process of the boiling water flowing through the water outlet pipe to the hot water discharge port 11, it will not be lost when it reaches the hot water discharge port 11. It can ensure that the water temperature is above 95°C, meeting the user's demand for high-temperature boiled water; in addition, the protection device 16 arranged on the fluid path downstream of the purified water outlet of the filter element 12 plays a role in water channel protection, which can limit the water flow pressure upstream of the water channel booster device 15 to below the first threshold value. When the water channel booster device 15 fails and completely blocks the water channel, the water flow pressure upstream of the water channel booster device 15 continues to rise to the first threshold value. The protection device 16 limits the water flow pressure upstream of the water channel booster device 15 to below the first threshold value by relieving pressure, controlling the filter unit to stop supplying water to the instant heating body, etc., to prevent the occurrence of pressure holding phenomenon, which may cause the water channel structure such as the instant heating body 14 to expand, burst and be damaged, thereby improving the safety of the integrated heat and water purification machine.

[0042] It should be noted that the present application does not limit the specific value of the first threshold value, and the value can be determined in the actual production process according to the actual pressure bearing capacity of the waterway system. The first threshold value should not exceed the upper limit of the actual pressure bearing capacity of the waterway system to ensure the safety of the waterway. Figure 1As shown, the water inlet of the heat and air purifier can be connected to the municipal faucet, and the water passage between the municipal faucet and the booster pump 13 can be controlled by the water inlet solenoid valve 19. The filter element 12 can be a single material filter element such as a PP filter element, an activated carbon filter element, an RO filter element, or a composite filter element composed of multiple materials. When the filter element 12 is an RO filter element or a composite filter element composed of an RO filter element, the wastewater outlet of the filter element 12 can be connected to the municipal sewer, and the water passage can be controlled by the wastewater solenoid valve 21. In addition, in order to realize the instant heating function of the instant heating body 14, the amount of water heated by the instant heating body 14 in the same time period is relatively small, and the clean water discharged from the filter element 12 cannot be heated up completely. Therefore, the clean water outlet of the filter element 12 can be connected to the reflux water path 22, and a flow limiting valve 23 is set on the fluid path from the filter element 12 to the instant heating body 14. The flow limiting valve 23 controls the water inlet flow rate of the instant heating body 14. During specific operation, a part of the clean water discharged from the filter element 12 enters the instant heating body 14 for heating, and the other part flows back to the front of the boosting pump 13 through the reflux water path 22. A one-way valve 221 can be set on the reflux water path 22.

[0043] To improve the functions of the heat and air purifier, Figure 1 As shown, the water purification and heating machine is also provided with a normal temperature water outlet 24 connected to the purified water outlet of the filter element 12, a first solenoid valve 25 is provided on the fluid path between the filter element 12 and the normal temperature water outlet 24, and a second solenoid valve 26 and a water pump 31 are provided on the fluid path between the filter element 12 and the instant heating body 14. The first solenoid valve 25 controls the water passage between the filter element 12 and the normal temperature water outlet 24. When the first solenoid valve 25 is opened, the filter element 12 can discharge normal temperature water to the normal temperature water outlet 24 to provide normal temperature purified water for the user. The second solenoid valve 26 controls the passage between the filter element 12, the instant heating body 14 and the reflux water passage 22. When the second solenoid valve 26 is opened, the water pump 31 can pump water to the instant heating body 14.

[0044] The present application does not limit the structure and location of the protection device 16, and the protection device 16 may adopt any one of the following embodiments:

[0045] Implementation method 1: Figure 1As shown, the water outlet of the instant heating body 14 is connected to the protection device 16 through the first water channel 27, and is connected to the hot water discharge port 11 through the second water channel 28. When the water flow pressure in the second water channel 28 reaches the second threshold, the water channel booster device 15 opens the second water channel 28. When the water flow pressure in the first water channel 27 reaches the first threshold, the protection device 16 opens the first water channel 27. The first threshold is greater than the second threshold. In this embodiment, the water outlet of the instant heating body 14 is connected to the protection device 16 and the hot water discharge port 11 through the first water channel 27 and the second water channel 28 respectively. When the water channel booster device 15 is in normal use, when the pressure of the hot water discharged by the instant heating body 14 reaches the second threshold, the water channel booster device 15 opens the second water channel 28, so that the hot water is normally discharged to the hot water discharge port 11. At this time, although the hot water discharged by the instant heating body 14 also enters a part of the first water channel 27, the protection device 16 is in a state of cutting off the first water channel 27. Therefore, the hot water The hot water cannot be discharged through the first water channel 27. When the water channel booster device 15 completely blocks the second water channel 28 due to a malfunction, the second water channel 28 cannot discharge hot water normally, and the water flow pressure of the heating body 14 continues to increase until it increases to a first threshold value, prompting the protection device 16 to open the first water channel 27, so that the heating body 14 releases pressure through the first water channel 27, and the pressure drops to normal pressure, thereby effectively protecting the water channel structure. When the pressure is released, the hot water discharged by the heating body 14 can be discharged to the outside of the entire machine, or it can flow back into the water tank of the heat and air purifier.

[0046] As a preferred embodiment of this implementation, the first threshold is at least twice greater than the second threshold. By making the first threshold at least twice greater than the second threshold, on the basis of ensuring that the waterway is safe and in normal use when the water flow pressure is less than the first threshold, the gap between the first threshold and the second threshold is increased as much as possible, ensuring that the protection device 16 is in a normally closed state during the normal operation of the waterway booster device 15.

[0047] As a preferred embodiment of this implementation, Figure 2As shown, the protection device 16 includes a first shell 161 and a first movable part 162 movably arranged in the first shell 161, the first shell 161 has a first water inlet 1611 and a first water outlet 1612, when the water flow pressure in the first water channel 27 is less than the first threshold value, the first movable part 162 cuts off the connection between the first water inlet 1611 and the first water outlet 1612, when the water flow pressure in the first water channel 27 is greater than or equal to the first threshold value, the first movable part 162 moves to connect the first water inlet 1611 and the first water outlet 1612. During specific installation, the protection device 16 is in the first water circuit 27, and the first water inlet 1611 corresponds to the water outlet of the instant heating element 14. When the first movable part 162 cuts off the connection between the first water inlet 1611 and the first water outlet 1612, the first water circuit 27 is also cut off at the same time, so that the instant heating element 14 can drain water normally to the hot water discharge port 11 through the second water circuit 28 but cannot drain water through the first water circuit 27. When the first movable part 162 connects the first water inlet 1611 and the first water outlet 1612 because the water pressure in the first water circuit 27 is greater than or equal to the first threshold value, the first water inlet 1611 and the first water outlet 1612 are also connected, and the first water circuit 27 is also connected, so that the instant heating element 14 can release pressure through the first water circuit 27. The overall structure of the protection device 16 is simple and easy to install. It is a non-electric structure and only needs to change its own state under the action of changes in water circuit pressure to cut off or connect the first water circuit 27, which helps to save costs.

[0048] Furthermore, when the water pressure in the first water channel 27 is less than the first threshold, the first movable member 162 is located at the first position blocking the first water inlet 1611; when the water pressure in the first water channel 27 is greater than or equal to the first threshold, the first movable member 162 moves toward the first water outlet 1612 to the second position and is confined to the second position so that the first water inlet 1611 and the first water outlet 1612 remain in a connected state. Figure 2The figure shows the state when the first movable part 162 is in the first position. In specific implementation, a spring 163 can be set between the first housing 161 and the first movable part 162. The elastic force of the spring 163 keeps the first movable part 162 in the first position when subjected to a water pressure less than the first threshold value. When the first movable part 162 is subjected to a water pressure not less than the first threshold value, it overcomes the elastic force of the spring 163 and moves toward the second position and is confined to the second position so that the first water inlet 1611 and the first water outlet 1612 remain in a connected state. In other words, after the protection device 16 moves from the first position to the second position, it can no longer be reset from the second position to the first position, that is, the protection device 16 is a non-self-resetting structure, so that when the water flow pressure in the first water path 27 is greater than or equal to the first threshold value, the protection device 16 opens and is in a normally open state, so that the pressure in the system quickly returns to normal pressure, effectively ensuring the safety of the entire system. Figure 3 The figure shows the state when the first movable member 162 is limited to the second position. Figure 3 The middle arrow indicates the fluid path of the protective device 16 when the first movable part 162 is confined to the second position. The present application does not limit the manner in which the first movable part 162 is confined to the second position. For example, the first movable part 162 may be confined by being snap-fitted with the first housing 161 when moving to the second position. Of course, other methods may also be used to confine the first movable part 162 to the second position.

[0049] Implementation method 2: Figure 4 As shown, the protection device 16 includes a temperature detection component 17 and a flow detection component 18 which are electrically connected to the control unit of the air conditioner and heat integrated machine respectively. The temperature detection component 17 is arranged on the fluid path between the instant heating body 14 and the water circuit boosting device 15, and the flow detection component 18 is arranged on the fluid path between the filter element 12 and the instant heating body 14. The temperature detection component 17 and the flow detection component 18 synchronously detect the water flow state upstream of the water circuit boosting device 15 and control the water flow state upstream of the water circuit boosting device 15 through the control unit. Specifically, the temperature detection element 17 is used to detect the water temperature of the water heated by the instant heating element 14, and the flow detection element 18 is used to detect the flow state of the water flow between the filter element 12 and the instant heating element 14. For example, when the water circuit booster 15 fails and blocks the water circuit, the pressure in the instant heating element 14 will continue to rise due to the pressurization and continuous heating of the water pump. When the temperature detection element 17 detects that the water temperature continues to rise and exceeds the set value and the flow detection element 18 detects that the water flow is still and not flowing, the temperature detection element 17 and the flow detection element 18 will feed back information to the control unit. The control unit can control the system to stop supplying water to the instant heating element 14, and at the same time control the instant heating element 14 to stop heating, so as to prevent the water pressure from exceeding the first threshold value, thereby effectively protecting the safety of the system.

[0050] The present application does not limit the structure of the waterway booster 15, which may adopt any one of the following embodiments:

[0051] Embodiment 1: Figure 5 As shown, the water channel boosting device 15 includes a second shell 151 and a second movable part 152 movably arranged in the second shell 151, the second shell 151 has a second water inlet 1511 and a second water outlet 1512, and an elastic part 153 is arranged between the second movable part 152 and the second shell 151. The second movable part 152 can overcome the elastic force of the elastic part 153 under the action of the upstream water flow pressure and move to the third position that connects the second water inlet 1511 with the second water outlet 1512, and can be reset to the fourth position that blocks the second water inlet 1511 under the action of the elastic force of the elastic part 153. The water circuit booster 15 is composed of a second housing 151, a second movable member 152 and an elastic member 153. Specifically, the water circuit booster 15 is installed between the instant heating body 14 and the hot water discharge port 11. The second water inlet 1511 corresponds to the water outlet of the instant heating body 14. The second movable member 152 switches position as the water pressure changes. When the water pressure discharged by the instant heating body 14 on the second movable member 152 is small (for example, less than the second threshold value mentioned above) and cannot push the second movable member 152 away, the second movable member 152 is located at the fourth position, and the second water inlet 1511 corresponds to the water outlet of the instant heating body 14. 511 and the second water outlet 1512 are not connected, and the heating body 14 and the hot water outlet 11 are also not connected, the water pressure upstream of the waterway booster 15 increases, the boiling point of the water flow rises, and the heating temperature of the heating body 14 is higher; when the water pressure discharged by the heating body 14 on the second movable member 152 is large (for example, greater than or equal to the second threshold value mentioned above), the second movable member 152 is pushed to the third position, and the second water inlet 1511 and the second water outlet 1512 are connected, then the heating body 14 and the hot water outlet 11 are connected, so that water flows out of the hot water outlet 11. When the water stops flowing, the second movable member 152 is reset from the third position to the fourth position by the elastic member 153, and the overall structure is simple, easy to install, and low in cost.

[0052] Embodiment 2: Figure 6As shown, the water circuit boosting device 15 is provided with a Tesla valve channel 154, and the Tesla valve channel 154 is reversely connected to the water outlet of the instant heating body 14, and is forwardly connected to the hot water discharge port 11. Specifically, the Tesla valve channel 154 is reversely connected to the water outlet of the instant heating body 14 through the third water inlet 1541, and is forwardly connected to the hot water discharge port 11 through the third water outlet 1542. When the instant heating body 14 discharges hot water to the hot water discharge port 11, the hot water flows through the Tesla valve channel 154 and is subject to the resistance of the Tesla valve channel 154, thereby achieving upstream water circuit boosting, the boiling point of the upstream water flow rises, the heating temperature of the instant heating body 14 is higher, and the water flow can flow to the hot water discharge port 11 after passing through the Tesla valve channel 154.

[0053] As a preferred implementation of the present application, Figure 1 As shown, the air-conditioning and heating integrated machine further includes a water vapor separation box 29 provided with a water vapor separation chamber, the water vapor separation box 29 is provided with an exhaust port 291, and the water circuit booster device 15, the exhaust port 291 and the hot water discharge port 11 are respectively connected to the water vapor separation chamber. The steam generated by the hot water entering the water vapor separation box 29 can be discharged from the exhaust port 291, and the hot water is discharged from the hot water discharge port 11, so that the water vapor separation is achieved and the jet and water flow splashing caused by the discharge of the hot water entrained with the steam are reduced.
