Description

Technical Field

[0001] This application relates to the technical field of electromechanical control, and in particular to a water outlet valve body control method based on a three-way motor and a wall-hung boiler. Background Technology

[0002] Currently, existing wall-hung boilers typically use a synchronous motor's outlet valve for three-way switching. In this method, heated water can only flow to either the large circulation heating pipe or the small circulation bathing pipe, not both simultaneously. This results in the heating function failing to activate when the bathing function is turned on, and vice versa. This creates a conflict between the use of bathing and heating functions in the wall-hung boiler. Specifically, when the boiler's zero-cold-water bathing function is activated, the heating function cannot be used, especially if the hot water pipes have poor insulation. This can prevent the heating system from starting, thus affecting indoor comfort. Therefore, improving the compatibility of bathing and heating functions in wall-hung boilers is a pressing technical problem that needs to be solved. Summary of the Invention

[0033] Example 1, see Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of a water outlet valve body control method based on a three-way motor provided in this application, as shown below. Figure 1 As shown, the method includes steps 101-102, as detailed below:

[0034] Step 101: When the currently triggered function state is detected to be a multi-function state, determine the first valve core movement state corresponding to the multi-function state, and control the three-way motor to drive the valve core to move based on the first valve core movement state; wherein, the first valve core movement state includes the valve core and the outlet valve housing being in a non-sealed state, and the valve core and the outlet valve housing forming a first channel and a second channel.

[0035] In one embodiment, the water outlet valve body includes, but is not limited to, a three-way motor 1, a water outlet valve housing 2, a water inlet 3, a small circulation bathing pipe 4, and a large circulation heating pipe 5.

[0036] like Figure 2 As shown, Figure 2This is a schematic diagram of the external structure of the outlet valve body shown in the embodiment of this application. The three-way motor 1 is located at the first end of the outlet valve body; the large circulation heating pipe port 5 is located at the second end of the outlet valve body, and the large circulation heating pipe port 5 is connected to the interior of the outlet valve body. The outlet valve housing 2 is used to enclose the outlet valve body. The water inlet port 3 penetrates the outlet valve housing 2 and is connected to the interior of the outlet valve body. The small circulation bathing pipe port 4 penetrates the outlet valve housing 2 and is connected to the interior of the outlet valve body. The water inlet port 3 is located between the large circulation heating pipe port 5 and the small circulation bathing pipe port 4.

[0037] In one embodiment, the three-way motor 1 is controlled and driven by the main controller 15 of the wall-hung boiler.

[0038] In one embodiment, the outlet valve body further includes a valve core located inside the outlet valve body; the valve core includes, but is not limited to, a first sealing ring 6, a first base 7, a first retaining ring 8, a first spring 10, a second sealing ring 13, a second base 14, a second retaining ring 12, a second spring 9, and a valve core moving shaft 11.

[0039] like Figure 3 As shown, Figure 3 This is a schematic diagram of the valve core structure shown in an embodiment of this application. The valve core moving shaft 11 is located inside the valve core. The first base 7 and the second base 14 are respectively fixed to both sides of the valve core moving shaft 11. The first sealing ring 6 is fixed to the first base 7, and the second sealing ring 13 is fixed to the second base 14. The first retaining ring 8 is fixed to the valve core moving shaft 11, with its first side fitting against the first base 7. The second retaining ring 12 is fixed to the valve core moving shaft 11, with its first side fitting against the second base 14. The first spring 10 is fixed to the valve core moving shaft 11, with its first side fitting against the first base 7. The second spring 9 is fixed to the valve core moving shaft 11, with its first side fitting against the second base 14.

[0040] In one embodiment, the main controller monitors the startup status of the wall-hung boiler in real time. When the wall-hung boiler starts, the function currently being executed by the wall-hung boiler is obtained and the function is used as the detected currently triggered function status. Preferably, the function currently being executed by the wall-hung boiler can be triggered by a physical button on the wall-hung boiler, or it can be automatically triggered based on preset rules.

[0041] In one embodiment, the multi-functional state includes at least one heating function, as well as other functions that the wall-hung boiler can perform besides the heating function; preferably, the multi-functional state includes both heating and bathing heating functions.

[0042] Specifically, the function currently being executed by the wall-hung boiler is obtained. When the function includes heating and bathing heating, the current triggered function state is determined to be a multi-functional state.

[0043] In one embodiment, by pre-setting a first valve core movement state corresponding to the multi-functional state, once the multi-functional state is detected to be triggered, the main controller will determine the first valve core movement state corresponding to the multi-functional state.

[0044] In one embodiment, the first valve core movement state includes the valve core position in the multi-functional state. Preferably, the valve core position is the middle position where the valve core movement shaft 11 is located inside the valve core.

[0045] In one embodiment, the valve core includes a first base 7, a second base 14, and a valve core moving shaft 11; wherein the first base 7 is located on the left side of the valve core, and the second base 14 is located on the right side of the valve core; based on the moving state of the first valve core, the three-way motor 1 is controlled to drive the valve core moving shaft 11 to move towards the center, so that the first base 7 and the inner inclined wall of the outlet valve housing 2 are in a non-sealed state, and the first base 7 and the inner inclined wall of the outlet valve housing 2 form the first channel, and the second base 14 and the inner inclined wall of the outlet valve housing 2 are in a non-sealed state, and the second base 14 and the inner inclined wall of the outlet valve housing 2 form the second channel.

[0046] like Figure 4 As shown, Figure 4 This is a schematic diagram of the valve core's movement in a multi-functional state as shown in the embodiments of this application. In the multi-functional state, the heating and bathing functions of the wall-mounted boiler are performed simultaneously. When the main controller 15 detects that the bathing and heating functions need to be performed simultaneously, it issues a control command to control the three-way motor 1 on the outlet valve body 16 to work. After receiving the control command, the three-way motor 1 starts to rotate and drives the valve core to move through the valve core moving shaft 11. During the movement, the valve core moving shaft 11 is controlled to move towards the middle. At this time, the valve core is in the middle position, and the first base 7 and the second base 14 are separated from the inclined wall inside the outlet valve housing 2, forming a non-sealed state. After the first base 7 is separated from the inclined wall inside the outlet valve housing 2, a first channel is formed between the two. At the same time, after the second base 14 is separated from the inclined wall inside the outlet valve housing 2, a second channel is formed between the two.

[0047] In one embodiment, the cross-sectional area of ​​the first channel is related to the distance between the first base 7 and the inner inclined wall of the outlet valve housing 2, and the cross-sectional area of ​​the second channel is related to the distance between the second base 14 and the inner inclined wall of the outlet valve housing 2. The valve core moving shaft 11 can adjust the distance between the first base 7 and the second base 14 and the inner inclined wall of the outlet valve housing 2 according to actual needs, thereby adjusting the cross-sectional area of ​​the first channel and the second channel respectively.

[0048] Specifically, the cross-sectional area of ​​the first channel is larger than that of the second channel; in this case, more water flowing into the inlet 3 will flow into the small circulation bathing pipe 4 for bathing; preferably, the ratio of the cross-sectional area of ​​the first channel to that of the second channel is 4:1; preferably, the ratio of the cross-sectional area of ​​the first channel to that of the second channel can also be 2:1; by controlling the ratio of the channel cross-sectional areas, the amount of water flowing into the small circulation bathing pipe and the large circulation heating pipe can be optimized, achieving a more reasonable allocation of resources.

[0049] Specifically, when the flow rate of water flowing into the inlet 3 is L0, after being split by the first and second channels in the outlet valve body, the flow rate of water flowing into the first channel is L1, and the flow rate of water flowing into the second channel is L2. The flow rate relationship of the water flow in this process is L0 = L1 + L2.

[0050] Step 102: When water flow is detected flowing into the water inlet, control the water flow to flow out from the small circulation bath pipe outlet through the first channel, and simultaneously control the water flow to flow out from the large circulation heating pipe outlet through the second channel.

[0051] In one embodiment, the first channel allows water to flow in from the water inlet 3 and out through the small circulation bathing pipe 4 for bathing; the second channel allows water to flow in from the water inlet 3 and out through the large circulation heating pipe 5 for heating, thus avoiding the problem that bathing heating and heating functions cannot operate simultaneously in the prior art and improving the user experience.

[0052] In summary, this embodiment detects the currently triggered function status. When the function status is detected to be multi-functional, the main controller adjusts the valve core position based on the three-way motor to form a first channel leading to the small circulation bath pipe and a second channel leading to the large circulation heating pipe. This allows the water flowing through the inlet to flow to the small circulation bath pipe and the large circulation heating pipe respectively through the first and second channels, solving the problem that bathing and heating functions cannot operate simultaneously in the prior art and improving the user experience.

[0053] Example 2, see Figure 5 , Figure 5 This is a flowchart illustrating another embodiment of the water outlet valve body control method based on a three-way motor provided in this application, as shown below. Figure 5 As shown, compared with Example 1, this method further includes steps 501-502, as detailed below:

[0054] Step 501: When the currently triggered functional state is detected to be a non-heating single-function state, determine the second valve core movement state corresponding to the non-heating single-function state, and control the three-way motor to drive the valve core to move based on the second valve core movement state; wherein, the second valve core movement state includes the valve core and the outlet valve housing forming a first single channel.

[0055] In one embodiment, the non-heating single-function state is set to any single function that the wall-hung boiler can perform other than the heating function; preferably, the non-heating single-function state is the bathing heating function.

[0056] Specifically, the function currently being executed by the wall-hung boiler is obtained. When the function is the bathing and heating function, the current triggered function state is determined to be a non-heating single-function state.

[0057] In one embodiment, by pre-setting the second valve core movement state corresponding to the non-heating single-function state, once the non-heating single-function state is detected to be triggered, the main controller will determine the second valve core movement state corresponding to the non-heating single-function state.

[0058] In one embodiment, the second valve core movement state includes the valve core position in the non-heating single-function state. Preferably, the valve core position is the right side position where the valve core movement shaft 11 is located inside the valve core.

[0059] In one embodiment, the valve core includes a first base 7, a second base 14, and a valve core moving shaft 11; wherein the first base 7 is located on the left side of the valve core, and the second base 14 is located on the right side of the valve core; based on the moving state of the second valve core, the three-way motor 1 is controlled to drive the valve core moving shaft 11 to move to the right, so that the first base 7 and the inner inclined wall of the outlet valve housing 2 are in a non-sealed state, the first base 7 and the inner inclined wall of the outlet valve housing 2 form the first single channel, and the second base 14 and the inner inclined wall of the outlet valve housing 2 are in a sealed state.

[0060] like Figure 6 As shown, Figure 6This is a schematic diagram of the valve core's movement in the non-heating single-function state shown in the embodiments of this application. In the non-heating single-function state, the wall-mounted boiler only turns on the bathing heating function. When the main controller 15 detects that the heating function is not needed, it issues a control command to control the three-way motor 1 on the outlet valve body 16 to work. After receiving the control command, the three-way motor 1 starts to rotate and drives the valve core to move through the valve core moving shaft 11. During the movement, the valve core moving shaft 11 is controlled to move to the right. At this time, the valve core is in the right position, and the first base 7 and the inner inclined wall of the outlet valve housing 2 are completely open, forming a first single channel between them. The second base 14 and the inner inclined wall of the outlet valve housing 2 are completely sealed, and no channel can be formed between them. As a result, only a single channel is formed between the water inlet 3 and the small circulation bathing pipe 4, namely the first single channel.

[0061] Step 502: When water is detected flowing into the water inlet, control the water to flow out from the small circulation bath pipe outlet based on the first single channel.

[0062] In one embodiment, when the water inlet 3 detects water flowing in, the water flows out through the first single channel from the small circulation bath pipe 4 to achieve the bathing function.

[0063] In one embodiment, when the flow rate of water flowing into the inlet 3 is L0, since there is only the first single channel in the outlet valve body, the flow rate of water flowing to the first single channel is L3, and the flow rate relationship of the water flow in this process is L0=L3.

[0064] In one embodiment, the duration of the non-heating single-function state is obtained, and when the duration is greater than a preset time threshold, the function state is automatically changed from the non-heating single-function state to the multi-function state.

[0065] Specifically, in the non-heating single-function state, the main controller 15 continuously monitors the duration of the wall-hung boiler in this state. If the duration exceeds a preset time threshold, i.e., the bathing time exceeds the preset time threshold, the main controller 15 will automatically control the three-way motor 1 to work, so that the three-way motor 1 drives the valve core to move, so that the valve core moves from the right side to the middle position. Based on the adjustment of the valve core position, the functional state is changed from the non-heating single-function state to the multi-function state, so as to provide low-load heating while ensuring that the bathing effect is not affected.

[0066] In summary, this embodiment detects the current triggered function status. When the function status is detected to be a non-heating single-function state, it can quickly drive the valve core to move to the corresponding position based on the three-way motor, ensuring that the water flow direction for bathing and heating is correct and improving the efficiency of bathing and heating.

[0067] Example 3, see Figure 7 , Figure 7 This is a flowchart illustrating another embodiment of the water outlet valve body control method based on a three-way motor provided in this application, as shown below. Figure 7 As shown, compared with Example 1, this method further includes steps 701-702, as detailed below:

[0068] Step 701: When the currently triggered function state is detected to be the heating single function state, the third valve core movement state corresponding to the heating single function state is determined, and based on the third valve core movement state, the three-way motor is controlled to drive the valve core to move; wherein, the third valve core movement state includes the valve core and the outlet valve housing forming a second single channel.

[0069] In one embodiment, the heating single-function state is set to heating function.

[0070] Specifically, the function currently being executed by the wall-hung boiler is obtained, and when the function is the heating function, the current triggered function state is determined to be the heating single function state.

[0071] In one embodiment, by pre-setting the third valve core movement state corresponding to the heating single function state, once the heating single function state is detected to be triggered, the main controller will determine the third valve core movement state corresponding to the heating single function state.

[0072] In one embodiment, the third valve core movement state includes the valve core position in the single-function heating state. Preferably, the valve core position is the left position where the valve core movement shaft 11 is located inside the valve core.

[0073] In one embodiment, the valve core includes a first base 7, a second base 14, and a valve core moving shaft 11; wherein the first base 7 is located on the left side of the valve core, and the second base 14 is located on the right side of the valve core; based on the third valve core moving state, the three-way motor 1 is controlled to drive the valve core moving shaft 11 to move to the left, so that the first base 7 and the inner inclined wall of the outlet valve housing 2 are in a sealed state, and the second base 14 and the inner inclined wall of the outlet valve housing 2 are in a non-sealed state, and the second base 14 and the inner inclined wall of the outlet valve housing 2 form the second single channel.

[0074] like Figure 8 As shown, Figure 8This is a schematic diagram of the movement state of the valve core in the single-function heating state shown in the embodiment of this application. In the single-function heating state, the wall-mounted boiler only turns on the heating function. When the main controller 15 detects that the heating function is needed, it issues a control command to control the three-way motor 1 on the outlet valve body 16 to work. After receiving the control command, the three-way motor 1 starts to rotate and drives the valve core to move through the valve core moving shaft 11. During the movement, the valve core moving shaft 11 is controlled to move to the left. At this time, the valve core is in the left position, and the second base 14 and the inner inclined wall of the outlet valve housing 2 are completely opened, forming a second single channel between them. The first base 7 and the inner inclined wall of the outlet valve housing 2 are completely sealed, and no channel can be formed between them. As a result, only a single channel is formed between the inlet 3 and the large circulation heating pipe 5, that is, the second single channel.

[0075] Step 702: When water is detected flowing into the water inlet, control the water to flow out from the large circulation heating pipe outlet through the second single channel.

[0076] In one embodiment, when water flow is detected at the water inlet 3, the water flows out from the large circulation heating pipe outlet 5 through the second single channel to achieve the heating function.

[0077] In one embodiment, when the flow rate of water flowing into the inlet 3 is L0, since there is only a second single channel in the outlet valve body, the flow rate of water flowing to the second single channel is L4, and the flow rate relationship of the water flow in this process is L0=L4.
