Description

Technical Field

[0001] The invention relates to a bathroom device, in particular to a shower. Background Art

[0002] The shower system is an indispensable device in today's families. The shower system generally has a top spray shower head, a second water outlet device and a water outlet controller. The top spray shower head, the second water outlet device and the water outlet controller are connected by a pipeline to form water outlet or water shutoff. When the top spray shower head or the second water outlet device switches from water outlet to water shutoff, it is inevitable that a part of the residual water between the pipes cannot continue to move toward the shower head and cannot be discharged, forming residual cold water. In the next shower, this part of the residual cold water will flow out first. If this part of the residual cold water flows directly to the user, the user will feel uncomfortable and the shower experience will be greatly affected. In the traditional shower system, there is no special design for this part of the residual cold water. The user can only drain it for a period of time before taking a shower to let the cold water drain. On the one hand, it is a waste of water. On the other hand, once the user forgets to drain the cold water, the cold water will be directly poured on the user, which is a very poor experience. In order to solve this problem, some shower systems are equipped with a separate cold discharge button. The user presses the cold discharge button before taking a shower to drain the cold water first, and then takes a shower. However, a separate cold water outlet needs to be provided on the shower, which makes the structure of the shower more complicated. Summary of the invention

[0003] The main technical problem to be solved by the present invention is to provide a cooling exhaust structure of a shower control panel, which can exhaust cooling from the water outlet terminal of the shower without the need to set up an additional cooling exhaust outlet.

[0004] Another technical problem to be solved by the present invention is to provide a cooling structure for a shower control panel, which can realize cooling of multiple water outlet terminals at the same time.

[0005] In order to solve the above technical problems, the present invention provides a cooling structure of a shower control panel, wherein the control panel has a water inlet channel and at least two water outlets, each of the water outlets is connected to the water inlet channel through a water outlet channel, and a first control switch for connecting or disconnecting the water inlet channel and the water outlet is provided on the water outlet channel;

[0006] It also includes a cooling channel corresponding to part or all of the water outlet channels and arranged in parallel, and the cooling channel and the corresponding water outlet channel share a water outlet; the cooling channel is provided with a second control switch that connects or closes the cooling channel to the water inlet channel.

[0007] In a preferred embodiment: the second control switch is used to control the cooling exhaust channels to be opened or closed simultaneously.

[0008] In a preferred embodiment: the water inlet channel includes a cold water inlet, a hot water inlet and a mixing water valve; the cold water inlet and the hot water inlet are respectively connected to the mixing water valve, and the mixed water outlet of the mixing water valve is connected to the first control switch and the second control switch.

[0009] In a preferred embodiment: a first check valve is provided in the cooling discharge flow channel, and the first check valve allows the residual water in the cooling discharge flow channel to flow unidirectionally toward the water outlet.

[0010] In a preferred embodiment: a third control switch is further provided between the second control switch and the water inlet channel; the third control switch is connected to the water outlet channel via a water replenishment channel.

[0011] In a preferred embodiment: when the second control switch is closed and the third control switch is opened, the water replenishment channel is connected to the water inlet channel; when the second control switch and the third control switch are opened, the cooling channel is connected to the water inlet channel.

[0012] In a preferred embodiment: a second check valve is provided in the water replenishment flow channel, and the second check valve allows the water in the water replenishment flow channel to flow unidirectionally toward the water outlet flow channel.

[0016] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0017] 1. The present invention provides a cooling structure for a shower control panel. By providing a cooling channel connected in parallel with a water outlet channel, the outlet of the water outlet channel can be used as the outlet of residual water, thereby realizing cooling from a water outlet terminal connected to the control panel. In addition, multiple cooling channels can be provided, which are connected in parallel with different water outlet channels, thereby realizing cooling from multiple water outlet terminals at the same time.

[0018] 2. The present invention provides a cooling structure for a shower control panel. Since the cooling channel and the water outlet channel are connected in parallel, the first control switch provided on the water outlet channel can be bypassed.

For example, "connection" can be a wall-mounted 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. It can be the internal connection 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.

[0034] refer to Figure 1-13 This embodiment provides a shower, including: a control panel 1 and a water outlet terminal 2 connected to the control panel 1; there are four water outlet terminals 2 in this embodiment, which are a two-function top spray shower, a lower water outlet terminal and a hand shower. This is just an example of this embodiment. The number of water outlet terminals 2 can be increased or decreased in specific design, which is a simple replacement of this embodiment.

[0035] In order to realize the water outlet of four water outlet terminals 2, the control panel 1 has a water inlet channel composed of a cold water inlet 11, a hot water inlet 12 and a mixing valve 13; it is also provided with water outlet channels 14 corresponding to the four water outlet terminals 2, and each water outlet channel 14 is provided with a water outlet 141 to connect with the corresponding water outlet terminal 2. And each water outlet channel 14 is provided with a first control switch 142 for connecting or disconnecting the water inlet channel and the water outlet 141. The first control switch 142 can be a mechanical switch, an electronic switch, or a control switch that is linked by electronics and mechanics. In this embodiment, the first control switch 142 adopts a mechanical switch, specifically a press switch water rotary regulating flow valve, and four mechanical switches are connected in parallel, and pressing can control whether each water outlet channel 14 outlets water or not.

[0036] Cold water and hot water flow into the mixing valve 13 through the cold water inlet 11 and the hot water inlet 12 respectively, and then mix to form mixed water, which flows out from the mixed water outlet 141 of the mixing valve 13. The function of the mixing valve 13 is to adjust the ratio of cold water and hot water entering the mixing valve 13, thereby adjusting the water temperature of the mixed water.

[0037] The control panel 1 is provided with a temperature detection device 15 and a flow detection device 16 at the rear end of the mixed water outlet 141 of the water mixing valve 13, so that the temperature and flow of the mixed water can be detected in real time, and the control panel 1 is also provided with a display screen 102 for displaying the temperature and flow, and the temperature and flow can be displayed on the display screen 102 by numbers or symbols. The significance of setting the flow detection device 16 is that the temperature detection device 15 is set in the water inlet flow channel and is at a long distance from the water outlet 141; therefore, during the cooling process, the temperature of the water outlet 141 will be lower than the temperature at the position of the temperature detection device 15. That is to say, when the temperature detector detects that the temperature of the mixed water in the channel has reached the preset temperature, the temperature of the water outlet 141 is still lower than the preset temperature. If the cooling is stopped at this time, the user will still feel that the outlet water temperature is too low, so the flow detection device 16 is set. When the temperature detector detects that the water temperature has reached the preset temperature, the control panel 1 starts to record the flow information through the flow detection device 16. When the flow reaches the set value, the cooling ends. This ensures that the outlet water temperature of the water outlet 141 reaches the user's set value when the user takes a shower. The set value of the flow depends on the pipe volume at the rear end of the temperature detection device 15. A flow controller 17, such as a water-saving sheet, is provided at the connection between the water inlet flow channel and the water outlet flow channel 14 to adjust the size of the water flow of each water outlet terminal 2.

[0038] In this way, the conventional function of the control panel 1 is completed, that is, controlling different water outlet terminals 2 to discharge water. The control panel 1 in this embodiment also has a main function, which is to discharge the residual water in the pipeline. The common way to discharge residual water is to discharge residual water through a separate cold discharge outlet. In this way, another cold discharge outlet must be opened on the control panel 1, which has a relatively complex structure and an ugly appearance. Therefore, the cold discharge scheme adopted in this embodiment is to use the existing water outlet terminal 2 for cold discharge. For this reason, the control panel 1 also includes a cold discharge channel 18 corresponding to part or all of the outlet flow channel 14 and arranged in parallel, and the cold discharge channel 18 and the corresponding outlet flow channel 14 share a water outlet 141; the cold discharge flow channel 18 is provided with a second control switch 181 that connects or closes the cold discharge flow channel 18 with the water inlet flow channel. In this embodiment, there are three cold discharge channels 18, corresponding to three of the four outlet flow channels 14. Of course, it can also be set to four cold discharge channels 18, corresponding to the four outlet flow channels 14 one by one. By providing a cooling channel 18 connected in parallel with the water outlet channel 14, the water outlet 141 of the water outlet channel 14 can be used as the water outlet 141 of the residual water, thereby realizing cooling from the water outlet terminal 2 connected to the control panel 1. In addition, multiple cooling channels 18 can be provided, which are respectively connected in parallel with different water outlet channels 14, thereby realizing cooling of multiple water outlet terminals 2 at the same time.

[0039] And because the cooling channel 18 and the water outlet channel 14 are connected in parallel, and the cooling channel 18 is directly connected to the water outlet 141 of the water outlet channel 14, the cooling channel 18 can bypass the first control switch 142 set on the water outlet channel 14. In this way, the user only needs to operate the second control switch 181 to achieve the cooling operation, which is relatively easy to operate.

[0040] In order to increase the efficiency of cooling, the second control switch 181 is used to control the cooling channel 18 to be opened or closed at the same time. As long as the second control switch 181 is turned on, the three water outlet terminals 2 connected to the cooling channel 18 will discharge cooling at the same time, which improves the cooling efficiency compared to the traditional method of discharging cooling from several different water outlets one by one.

[0041] The second control switch 181 preferably adopts a solenoid valve. Before the user enters the shower, the control switch 181 is turned on by remote control wireless control, and the three water outlet terminals 2 connected to the cooling channel 18 will discharge the cooling at the same time, and the residual water in the top spray, handheld and lower water outlet channels will be discharged at one time; of course, other methods can also be used, such as adding a distance sensor to the control panel. When the user is about to approach the shower, the distance sensor is electrically connected to the control main board, and then the control main board controls to open the control switch 181 for full cooling. It is also possible to set the control main board on the control panel 1 to discharge the cooling once at a certain time, and each time the cooling is preset for a certain duration, for example, once every 4 hours, and each time the cooling is discharged for 10 seconds. This can be set in the program on the control main board of the control panel.

[0042] At the same time, in order to prevent the residual water in the cold discharge channel 18 from flowing into the water outlet channel 14, a first check valve 182 is provided in the cold discharge channel 18, and the first check valve 182 allows the residual water in the cold discharge channel 18 to flow unidirectionally toward the water outlet 141. In this way, the residual water in the cold discharge channel 18 can only flow unidirectionally, and there is no need to worry about the residual water entering the water outlet channel 14 and flowing out of the water outlet channel 14 when the user takes a normal shower. On the contrary, it is also possible to prevent the water in the water outlet channel 14 from entering the cold discharge channel 18 and causing water to flow out of other water outlets 141. That is to say, if the first check valve 182 is not provided in the cold discharge channel 18, if the first control switch 142 of the hand-held shower channel is turned on, the water will flow through the cold discharge channel 18 and flow back through other cold discharge channels 18, causing water to flow out of other water outlet terminals 2.

[0043] In order to further increase the functions of the control panel 1 in this embodiment, a third control switch 191 is further provided between the second control switch 181 and the water inlet channel. The third control switch 191 is connected to the water outlet channel 14 through the water replenishment channel 192. In this way, the residual water has two flow modes: Mode 1: When the second control switch 181 is closed and the third control switch 191 is opened, the water replenishment channel 192 is connected to the water inlet channel, and at this time, the residual water enters the water inlet channel for water replenishment, and increases the water output of the water outlet terminal 2 when the water outlet terminal 2 is normally outputting water; Mode 2: When the second control switch 181 and the third control switch 191 are opened at the same time, the cold discharge channel 18 is connected to the water inlet channel, and at this time, the residual water is discharged from the water outlet terminal 2 through the cold discharge channel 18.

[0044] Similarly, in order to prevent the water in the water supply channel 192 from flowing back, a second check valve 193 is provided in the water supply channel 192, and the second check valve 193 allows the water in the water supply channel 192 to flow in a one-way direction toward the water outlet channel 14. At the same time, it can also prevent the mixed water in the water mixing valve from passing through the flow detector to the second control switch 181 and then out through the cold discharge channel 18, because the mixed water in the water mixing valve always has water in the water path passing through the flow detector. If the one-way valve is installed in reverse, when the second control switch is controlled to be opened, the residual water path will be in a water discharge state.

[0045] See also Figure 4 , Figure 5 and Figure 6 , the hot and cold mixed water coming out of the mixing valve passes through the flow controller on one side, then passes through the four first control switches 142, and finally passes through the handheld, top spray or bottom water outlet for the user to take a shower, and the other side passes through the second control switch 181, and then passes through the residual water channel to discharge the residual water from the same outlet of the terminal. As for the setting of the outlet channel 14 and the cold discharge channel 18, in this embodiment, the outlet channel 14 is connected to the water inlet channel through the bypass 143, and the bypass 143 is also connected to the side outlet 145 through the upper water inlet 144, and the side outlet 145 is connected to the cold discharge channel 18; the solenoid valve installation cavity 146 is set at the connection between the bypass 143 and the upper water inlet 144, so that the second control switch 182 is used to control the conduction and closing of the bypass 143 and the upper water inlet 144. Therefore, when the second control switch 182 is turned on, the residual water enters the upper water inlet 144 from the bypass 143, and then enters the cold discharge channel 18 from the side outlet 145.

[0046] After the residual water flows out from the side water outlet 145, it first enters the first row of cold runners 183; the residual water entering the first row of cold runners 183 is divided into two paths, one path flows in from the two water inlets 1835 on the inner side of the first row of cold runners 183, and then flows out from the first outflow hole 1831 and the second outflow hole 1832 respectively after passing through the two check valves of the two runners inside the water channel assembly, the residual water passing through the first outflow hole 1832 passes through the second row of cold runners 184 and is discharged from the first water outlet 1841, the residual water passing through the second outflow hole 1833 passes through the third row of cold runners 185 and is discharged from the second water outlet 1851, and the other path continues to go downward through the first row of cold runners 183, then passes through the third inlet 1833 into the water channel, passes through the internal channel and then comes out from the third water outlet 1834; in this way, the water channel of the entire water channel assembly is arranged compactly, the water flow will not flow in series, and the space is compact.

[0047] refer to Fig.11 The residual water flows in from the third inlet 1833, flows out from the third outlet 1834 through the check valve, and the residual water flows from bottom to top. Fig.11 on the left side.

[0048] refer to Fig.12 The residual water flows out from the first outflow hole 1831 through the check valve and out of the first water outlet 1841. The residual water flows from top to bottom. Fig.12 on the right.

[0049] refer to Fig.13 The residual water flows out of the second outflow hole 1832 through the check valve and is discharged from the second water outlet 1851; the water flows from bottom to top Fig.13 on the left.

[0050] In addition, the shower rod is provided with a human body sensor 103 for sensing the position of the user, and the human body sensor 103 can be a distance sensor such as infrared, microwave, laser, etc. The human body sensor 103 can detect whether the user is within the water outlet coverage of the shower device. In normal use of the shower, if the human body sensor 103 recognizes that the user leaves the coverage of the shower, the flow rate of the current water outlet terminal 2 is automatically reduced, which plays a role in saving water and energy.

[0051] The second control switch 181 is an electric control valve, which is used in conjunction with a wireless remote controller. The wireless remote controller can send a cooling command to the control mainboard 10 of the shower, and the control mainboard 10 controls the second control switch 181 to open after receiving the command, and performs the cooling action.

[0052] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
