Description

Technical Field

[0001] The utility model relates to bathroom products, 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, a second water outlet device and a water outlet controller. The top spray shower, the second water outlet device and the water outlet controller are connected by a pipeline to form water outlet or water shutoff. When the shower is over, the shower controller is turned off, and the water between the water heater and the shower controller will slowly cool down. In the next shower, this part of the cold water will flow out first. In some families (especially in central heating areas), the distance between the water heater and the shower controller is far, and it often takes a long time to drain this part of the cold water. Waiting for the drain to be completed will waste time. If people leave, the valve may not be closed in time after the drain is completed, which will waste a lot of hot water. Traditional shower controllers have not made special designs for this, and the experience is very poor. In order to solve this problem, some shower systems have a separate drain button. Users press the drain button before taking a shower to drain the water first, and then take a shower. However, it is difficult for users to judge whether the drain is over, and the structure of this shower controller is relatively complex and difficult to repair. Utility Model Content

[0039] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0041] In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "installed / connected", "connected", etc. should be understood in a broad sense. 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 utility model can be understood according to specific circumstances.

[0042] refer to Figure 1-Figure 17 , this embodiment provides a shower system, including a water outlet terminal and a shower controller 1. In this embodiment, there are two water outlet terminals, namely a hand-held shower 2 and an overhead shower 3. The shower controller 1 is used to control and switch different water outlet terminals to discharge water. It should be noted that the water outlet terminals are not limited to two, nor are they limited to overhead showers 3 and hand-held showers 2. The shower controller 1 in this embodiment is a concealed shower controller 1, and as a simple replacement, it can also be an exposed shower controller 1.

[0043] In this embodiment, the shower controller 1 is a shower controller 1 with a cooling function, comprising: a first valve body 11, a cooling valve 12 and a first water diversion valve 13; the first valve body 11 is provided with a first chamber 111 for installing the cooling valve 12, and a second chamber 112 for installing the first water diversion valve 13;

[0044] The cold discharge valve 12 is provided with a cold discharge water inlet 121, a cold discharge water outlet 122 and a cold discharge flow channel 123 connected therebetween; the cold discharge water outlet 122 is connected to the water outlet channel 113 provided on the first valve body 11; the first valve body 11 is provided with a cold discharge channel 114 between the first chamber 111 and the second chamber 112, the water outlet of the cold discharge channel 114 is connected to the cold discharge water inlet 121; the water inlet of the cold discharge channel 114 is provided on the second chamber 112; that is, when the first water diversion valve 13 is switched to the cold discharge state, the residual water flows into the cold discharge channel 114 through the water inlet of the cold discharge channel 114 on the second chamber 112, and then flows into the cold discharge valve 12 through the cold discharge water inlet 121 to perform the cold discharge operation. When the residual water is discharged, the water temperature flowing into the cold discharge valve 12 rises, and the cold discharge valve 12 closes the cold discharge channel 114 to complete the cold discharge operation.

[0045] After the cooling is finished, the user needs to be informed that the cooling has ended. To this end, the first valve body 11 is also provided with a first flow channel 115 and a second flow channel 116 connected to the water outlet channel 113, wherein the second flow channel 116 is a normally open flow channel, and the water flow area of ​​the second flow channel 116 is smaller than the first flow channel 115; the first water diverter valve 13 is in the first state or the second state under the action of an external force, and when the first water diverter valve 13 is in the first state, the first flow channel 115 is closed and the cooling channel 114 is opened; when the first water diverter valve 13 is in the second state, the first flow channel 115 is opened and the cooling channel 114 is closed. In this way, after the cooling is finished, the first water diverter valve 13 is still in the first state. At this time, since the cooling valve 12 has closed the cooling channel 114, the water can only flow out from the second flow channel 116. Because the water flow area of ​​the second flow channel 116 is relatively small, the water outlet terminal will present a small flow water outlet state to remind the user. This time, the user can operate the first water diversion valve 13 again to switch the first water diversion valve 13 to the second state, and open the first flow channel 115. Water flows out of the first flow channel 115, and is in a normal use state.

[0046] The first water-dividing valve 13 in this embodiment is a key-operated water-dividing valve, which drives the valve stem to move up and down through a ballpoint pen switching mechanism to close or open the first flow channel 115 and open or close the cold exhaust channel 114 at the same time.

[0047] In order to realize that the cold discharge valve 12 is automatically closed after the cold discharge is completed, the cold discharge valve 12 is built with a temperature sensing element 121. The temperature sensing element 121 is affected by the water temperature in the cold discharge channel 123 to drive the sealing element 128 to be located at the first position or the second position; when the sealing element 128 is located at the first position, the cold discharge channel 123 is opened, and when the sealing element 128 is located at the second position, the cold discharge channel 123 is closed. The temperature sensing element 121 is a component that can be extended or shortened by the water temperature. It is widely used in thermostatic valve cores and belongs to the prior art. It is not described in detail in this embodiment.

[0048] In order to realize the function of the cold discharge valve 12, the cold discharge valve 12 also includes a second valve body 124, a valve seat 125 and a reset member 126; the second valve body 124 defines a chamber for installing the temperature sensing element 121, and a cold discharge channel 123 outside the chamber; the bottom of the valve body 11 is provided with the cold discharge water inlet 121, and the side wall is provided with the cold discharge water outlet 122. One end of the temperature sensing valve core is threadedly connected to the chamber for fixation, and the other end is placed in the chamber and connected to the sealing member 128.

[0049] In order to realize that the seal 128 can open or close the cold exhaust channel 123. The cold exhaust channel 123 is divided into a first part and a second part that are connected to each other; the first part is arranged radially outside the second part; when the seal 128 is in the second position, the seal 128 seals the connection between the first part and the second part; when the seal 128 is in the first position, the seal 128 opens the connection between the first part and the second part.

[0050] In this embodiment, the valve seat 125 is arranged outside the bottom of the second valve body 124, and the valve seat 125 abuts against the sealing member 128 through the reset member 126; when the sealing member 128 is in the second position, the reset member 126 is squeezed to accumulate elastic reset force. In this way, after the cooling is discharged, the temperature sensing element 121 contracts, and the reset member 126 releases the elastic reset force to push the sealing member 128 to move to the second position to close the cooling channel 123.

[0051] Specifically, the sealing member 128 includes a valve core and a sealing ring disposed on the valve core; the valve core is connected to the temperature sensing element 121 via a push rod 127; thus, when the temperature sensing element 121 is extended, the push rod 127 drives the valve core to move to the first position.

[0052] In order to reduce the force required for the valve core to move and avoid the situation where the valve core does not move, the valve core is provided with a water pressure balance hole 127 for connecting the chamber and the cold exhaust channel 123. In this way, the water pressure inside and outside the chamber can be balanced, and the valve core is in a water pressure balance state when it is stationary. As long as the force applied by the extension of the temperature sensing element 121 is sufficient to drive the valve core to move.

[0053] One end of the water outlet channel 113 is respectively connected to the cold water outlet 122, the first flow channel 115 and the second flow channel 116. In this way, the water outlets of the first flow channel 115, the second flow channel 116 and the cold water outlet flow channel 123 will eventually flow into the water outlet channel 113, and the other end of the water outlet channel 113 is connected to the water inlet of the second water diversion valve 14. The valve body 11 is provided with a third chamber 117 for installing the second water diversion valve 14.

[0054] The water outlet channel can be connected to the first water outlet terminal channel 118 or the second water outlet terminal channel 119 provided on the valve body 11 through the second water diversion valve, thereby achieving water outlet of the first water outlet terminal or the second water outlet terminal.

[0055] The shower controller with the cooling function is provided with a normally open second flow channel 116, and the flow area of ​​the second flow channel 116 is relatively small. After the cooling is finished, the cooling flow channel of the cooling valve 12 will automatically close. Since the second flow channel 116 remains normally open, the water outlet terminal will be in a small flow state to remind the user that the cooling is finished. The user can operate the first water diversion valve 13 to open the first flow channel 115 to discharge water normally. The cooling valve 12 and the first water diversion valve 13 are each installed separately in the installation cavity, and are not integrated together. The cooling valve 12 is installed in the first chamber 111, and the first water diversion valve 13 is installed in the second chamber 112. The cooling valve 12 has only one cooling flow channel, and the first water diversion valve 13 is used to connect the cooling channel 114, the first flow channel 115 and the water outlet channel 113. The cold discharge channel 114, the first flow channel 115 and the second flow channel 116 are arranged in the valve body 11, and the water inlet of the cold discharge channel, the first flow channel 115 and the second flow channel 116 are arranged on the inner wall of the second chamber 112. When the cold discharge valve 12 or the first water diverter valve 13 is damaged, it is easy to open the cover to replace the cold discharge valve 12 or the first water diverter valve 13 separately. When the cold discharge valve 12 is damaged, it can be switched to normal water outlet to replace the cold discharge valve 12 without affecting normal use, so it has the effect of convenient maintenance. After long-term use, even if the cold discharge valve 12 fails, it will not affect normal use.

[0056] Since the second water diverter valve in this embodiment uses a rotational switching method to select the handheld shower 2 and the overhead shower 3 to discharge water, as a simple replacement for this embodiment, the second water diverter valve can also be eliminated, and a switch valve can be provided in the first water outlet terminal flow channel 118 or the second water outlet terminal flow channel 119 to open the first water outlet terminal flow channel 118 or the second water outlet terminal flow channel 119.

[0057] In addition, the shower controller in this embodiment has cold water and hot water inlet channels, so that cold water and hot water enter the main control valve core respectively and then mix and enter the first water diversion valve 13. The main control valve core can have the functions of temperature adjustment, flow adjustment and water switching. The temperature adjustment function of the main control valve core can be conventional temperature adjustment or temperature adjustment with constant temperature characteristics.

[0058] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
