Description

Technical Field

[0001] The present application belongs to the field of valve technology, and more specifically, relates to an inlet and outlet water valve module. Background Art

[0002] The water inlet and outlet valve module is an important module commonly found in wall-mounted boiler systems and is used to participate in water flow and heat exchange.

[0003] Conventional water inlet and outlet valve modules primarily consist of an inlet valve, an outlet valve, and a heat exchanger. Cold water flows through the inlet valve into the heat exchanger, where it is heated and then sent to the outlet valve. Hot water is then delivered to the heating system and bathrooms through the outlet valve's hot water and heating channels, meeting the household's heating and hot water needs.

[0004] However, since the hot water flowing out of the bathroom hot water channel in the water outlet valve is the hot water generated by the heat exchanger, when the power of the wall-mounted boiler is too high, the temperature of the hot water generated by the heat exchanger tends to increase accordingly, resulting in the hot water temperature flowing out of the bathroom hot water channel of the water outlet valve being too high, which not only affects the user experience but also poses a risk of scalding, and urgently needs improvement. Utility Model Content

[0005] In response to the defects or improvement needs of the existing technology, the present application provides an inlet and outlet water valve module, which aims to improve the problem of excessively high temperature of hot water flowing out of the hot water channel of the bathroom.

[0006] The present application provides a water inlet and outlet valve module, which specifically includes a water inlet valve, a water outlet valve and a heat exchanger, wherein the water inlet valve and the water outlet valve are both connected to the heat exchanger;

[0007] The inlet and outlet valve module also includes a connecting pipe, one end of which is connected to the water inlet channel of the water inlet valve, and the other end is connected to the bathroom hot water channel of the water outlet valve. The cold water flowing into the water inlet channel of the water inlet valve can flow through the detection end of the water flow sensor in the water inlet valve, and then flow into the bathroom hot water channel of the water outlet valve along the connecting pipe to mix with the hot water, and

[0008] The water inlet and outlet valve module also includes a control valve for adjusting the flow rate of cold water flowing into the bathroom hot water channel.

[0009] Through the above technical scheme conceived by the present application, compared with the existing technology, the inlet and outlet valve module is provided with a connecting pipe connecting the water inlet valve and the water outlet valve, so that the cold water in the water inlet valve can directly pass through the connecting pipe to the bathroom hot water channel of the water outlet valve, thereby adjusting the excessively high water temperature in the bathroom hot water outlet water path and realizing temperature readjustment of bathroom water; in addition, since a water flow sensor is provided in the water inlet valve, the flow of cold water flowing to the water outlet valve can be measured by the water flow sensor, which is conducive to accurate control of the cold water supply.

[0010] As a further preference, the connecting pipe and the heat exchanger are arranged on opposite sides of the water outlet valve.

[0011] As a further preferred embodiment, a cold water inlet is provided on the water outlet valve, and the connecting pipe is connected to the bathroom hot water channel of the water outlet valve through the cold water inlet.

[0012] As a further preference, the control valve is connected in series between the outlet of the connecting pipe and the cold water inlet.

[0013] As a further preference, the control valve is a servo regulating valve.

[0014] As a further preferred embodiment, the bathroom hot water channel of the water outlet valve has a temperature regulating section for mixing and regulating the temperature of cold water flowing in from the connecting pipe and hot water flowing in from the heat exchanger.

[0015] As a further preference, a water mixer for mixing cold water and hot water is provided in the temperature adjustment section.

[0016] As a further preferred embodiment, a water mixing channel for water to flow through is formed in the water mixer, and a water mixing structure for stirring the water flow is provided in the water mixing channel.

[0017] As a further preferred embodiment, the water mixing structure is arranged at the water inlet of the water mixing channel, and the inner wall of the water mixing channel cooperates with the water mixing structure to form a multi-channel stirring flow section. The water mixing channel also has a single-channel confluence section, which is connected to the multi-channel stirring flow section.

[0018] As a further preference, the water mixing structure is a spiral guide structure.

[0019] In general, the above technical solutions conceived by this application have the following technical advantages compared with the existing technologies:

[0020] 1. This inlet and outlet valve module is equipped with a connecting pipe, allowing cold water in the water inlet valve to flow directly through the connecting pipe to the bathroom hot water channel of the water outlet valve. The cold water and hot water are evenly mixed through the mixer in the bathroom hot water channel, thereby quickly adjusting the excessively high water temperature in the bathroom hot water outlet waterway and achieving temperature readjustment of the bathroom water.

[0021] 2. The flow rate of cold water flowing into the outlet valve can be measured by a water flow sensor, which is conducive to accurate control of the cold water supply.

[0030] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0032] The embodiment of the present application discloses a water inlet and outlet valve module. Figure 1-Figure 3 The inlet and outlet valve module includes an inlet valve 1, an outlet valve 2 and a heat exchanger 3. The inlet valve 1 and the outlet valve 2 are both connected to the heat exchanger 3. The inlet and outlet valve module also includes a connecting pipe 4. One end of the connecting pipe 4 is connected to the water inlet channel of the inlet valve 1, and the other end of the connecting pipe 4 is connected to the bathroom hot water channel 2-1 of the outlet valve 2. The cold water flowing into the water inlet channel of the inlet valve 1 can flow through the detection end of the water flow sensor in the inlet valve 1, and then flow along the connecting pipe 4 into the bathroom hot water channel 2-1 of the outlet valve 2 to mix with the hot water. In addition, the inlet and outlet valve module also includes a control valve 5 for adjusting the flow rate of cold water flowing into the bathroom hot water channel 2-1.

[0033] Specifically, the water inlet valve 1 is provided with a cold water outlet 1-1, which communicates with the water inlet channel of the water inlet valve 1. The water outlet valve 2 is provided with a cold water inlet 2-2, which communicates with the bathroom hot water channel 2-1 in the water outlet valve 2. A connecting pipe 4 connects the cold water inlet 2-2 and the cold water inlet 2-2, respectively, allowing the cold water in the water inlet valve 1 to flow into the water outlet valve 2.

[0034] It should be clear that in the water inlet valve 1, the detection end of the water flow sensor extends into the water inlet channel, and the detection end of the water flow sensor is located upstream of the cold water outlet 1-1, which allows the flow of cold water flowing to the water outlet valve 2 to be measured by the water flow sensor.

[0035] Further, such as Figure 1 and Figure 2 As shown, in this embodiment, the connecting pipe 4 and the heat exchanger 3 are arranged on opposite sides of the water outlet valve 2. Under this design, the structural layout of the water inlet and outlet valve module is reasonable, and the heat energy dissipated by the heat exchanger 3 has little effect on the connecting pipe 4.

[0036] Furthermore, the installation position of the control valve 5 can be flexibly adjusted and selected based on actual needs. For example, the control valve 5 can be connected in series between the connecting pipe 4 and the cold water inlet 2-2; the control valve 5 can be connected in series between the connecting pipe 4 and the cold water outlet 1-1; or the connecting pipe 4 can be composed of multiple pipe sections connected in series, with the control valve 5 installed in series between two adjacent pipe sections.

[0037] As a preferred Figure 1 and Figure 2 As shown, in this embodiment, the control valve 5 is connected in series between the outlet of the connecting pipe 4 and the cold water inlet 2-2. The control valve 5 includes but is not limited to a servo regulating valve.

[0038] Furthermore, in order to improve the mixing effect of cold water and hot water in the water outlet valve 2, the bathroom hot water channel 2-1 of the water outlet valve 2 has a temperature adjustment section for mixing and adjusting the temperature of the cold water flowing into the connecting pipe 4 and the hot water flowing into the heat exchanger 3.

[0039] Furthermore, in some embodiments, the outlet valve 2 further comprises a water mixer 6 disposed in the temperature adjustment section for mixing cold water and hot water. After the water mixer 6 is provided, the cold water and hot water in the outlet valve 2 can be mixed faster and more evenly.

[0040] Specifically, if Figure 3 and Figure 4As shown, in some specific embodiments, the water mixer 6 includes a shell 6-1, the outer surface of the shell 6-1 is in close contact with the inner wall of the bathroom hot water channel 2-1, and a mixing channel for water flow is formed in the shell 6-1. The mixing channel has a water inlet and a water outlet, and a mixing structure for stirring the water flow is provided in the mixing channel.

[0041] In some embodiments, a water mixing structure is positioned at the water inlet of the mixing channel. The inner wall of the mixing channel and the water mixing structure cooperate to form a multi-channel agitation section. The mixing channel also includes a single-channel converging section that communicates with the multi-channel agitation section. This design achieves both agitation and converging of water flows, promoting mixing of cold and hot water.

[0042] Of course, in some embodiments, the single-channel confluence section may not be provided in the water mixing channel. In some embodiments, the water mixing structure may be provided at other locations in the water mixing channel, such as at the water outlet of the water mixing channel, as long as the location allows the water mixing structure to achieve the effect of disturbing / stirring the water flow.

[0043] Furthermore, in some embodiments, the water mixing structure includes, but is not limited to, a spiral guide structure. For example, it may also be a mesh structure, a porous structure, a staggered water baffle structure, etc. When a spiral guide structure is selected, the water flowing through the spiral guide structure will generate a spiral, thereby stirring the water flow and promoting the mixing of hot and cold water.

[0044] For ease of understanding, Figure 4 and Figure 5 A spiral flow guide structure is shown, which includes a central reinforcement member 6-2 and multiple spiral blades 6-3. The central reinforcement member 6-2 is coaxially arranged within the shell 6-1, and the multiple spiral blades 6-3 are distributed along the circumference of the central reinforcement member 6-2 and connected between the central reinforcement member 6-2 and the shell 6-1 of the water mixer 6.

[0045] The area enclosed by the central reinforcement 6-2, spiral blades 6-3, and the inner wall of the housing 6-1 is the multi-channel agitation section; the section of the housing 6-1 away from the spiral blades 6-3 is the single-channel converging section. Generally speaking, the central reinforcement 6-2 is a rod, and the central reinforcement 6-2, spiral blades 6-3, and housing 6-1 are preferably manufactured using an integral molding process.

[0046] Furthermore, in some embodiments, in order to fully ensure that the water flow in the water mixer 6 can be discharged smoothly, the water mixing channel can be provided with multiple water outlets, and at least one water outlet is connected to the bathroom hot water outlet 2-3 at the end of the bathroom hot water channel 2-1.

[0047] In some embodiments, the water outlets include a plurality of lateral water outlets 6-4 formed on the circumferential surface of the housing 6-1 of the mixer 6, and / or end surface water outlets 6-5 formed on the end surface of the housing 6-1 of the mixer 6. Generally speaking, the form and number of the water outlets can be selected and designed based on the layout of the bathroom hot water outlets 2-3 and the mixer 6.

[0048] For example: In some solutions where the hot water outlet 2-3 of the bathroom is not coaxial with the mixer 6 (e.g. Figure 3 In the illustrated arrangement where the bathroom hot water outlet 2-3 is located on the side of the mixer 6, a lateral outlet 6-4 can be used to communicate with the bathroom hot water outlet 2-3. In some arrangements where the cold water inlet and mixer 6 are coaxially connected in series, an end outlet 6-5 can be used to communicate with the bathroom hot water outlet 2-3.

[0049] Furthermore, in the water mixer 6 used in this embodiment, the water mixer 6 is provided with both a lateral water outlet 6-4 and an end water outlet 6-5. Preferably, the water mixer 6 is detachably connected to the main body of the water outlet valve 2.

[0050] Furthermore, in some embodiments, the water inlet and outlet valve modules also include a temperature sensor for detecting the water temperature at the bathroom hot water outlet 2-3. Preferably, the temperature sensor is installed in the bathroom hot water channel 2-1, close to the bathroom hot water outlet 2-3, to effectively monitor changes in the outlet water temperature. Examples of temperature sensors include, but are not limited to, NTC.
