[0043] In the related art, the water circuit of the double ice-making refrigerator includes a main water valve, a filter element and a post-water valve. The main water valve, the filter element and the post-water valve are connected in series in sequence. The inlet of the main water valve is connected to the external water source through a pipeline, and the three outlets of the post-water valve are connected to the drinking water pipeline, the refrigerated ice-making pipeline 34 and the frozen ice-making pipeline 33 respectively. Due to the use of such a pipeline structure design, when any of the dispenser drinking water, refrigerated ice-making and frozen ice-making requests water inlet, the main water valve will be opened. According to statistics, the drinking water pipeline is used 10 times a day, the refrigerated ice-making pipeline 34 is used 15 times a day, and the frozen ice-making pipeline 33 is used 13 times a day. In this way, the main water valve needs to be operated 38 times a day. According to the 10-year warranty period, the maximum number of times the valve core of the main water valve is used is 38*365*10=138700 times, and the life of a single valve core is 100,000 times. Therefore, the valve core of the main water valve is easily damaged during the warranty period, which seriously affects the stability of the refrigeration equipment and reduces the user experience.

[0044] Figure 1 The three-dimensional structure diagram of the piping device of the refrigeration equipment provided in the embodiment of the present application is illustrated as follows: Figure 1As shown, the pipeline device of the refrigeration equipment includes a main valve 10, a water circuit connection assembly 20 and a water circuit control assembly 30. The inlet of the main valve 10 is connected to the water inlet pipe, the water inlet pipe is connected to the water source, and the water source supplies water to the water circuit. The main valve 10 has multiple outlets. Specifically, the main valve 10 is a one-inlet and multiple-outlet valve. The water circuit connection assembly 20 has at least two flow channels, and the outlet of the main valve 10 is connected to the flow channels in a one-to-one correspondence. At least two flow channels of the water circuit control assembly 30 are connected to the inlet of the water circuit control assembly 30. The water circuit control assembly 30 is suitable for distributing water in the pipeline device to different pipelines.

[0045] It should be noted here that the specific type of the main valve 10 is not limited to a one-inlet and multiple-outlet valve, and may also be a two-inlet and multiple-outlet valve or a multiple-inlet and multiple-outlet valve.

[0046] According to the piping device of the refrigeration equipment in the embodiment of the present application, a water connection assembly 20 is arranged between the main valve 10 and the water control assembly 30, and a one-inlet and multiple-outlet valve is used in conjunction with the water connection assembly 20, so that each valve core of the main valve 10 controls the opening and closing of the corresponding flow channel, so that the number of actions of each valve core of the main valve 10 will not exceed the maximum life number of the single valve core, effectively solving the problem that the main water valve of the dual ice-making machine type cannot meet the life requirement, eliminating the hidden dangers of failure due to overdue life from the source, and improving the reliability of the whole machine.

[0047] It can also be understood that the water channel connection assembly 20 includes a multi-way piece, and the multi-way piece has multiple flow channels inside, one of which is connected to the remaining flow channels and the inlet of the water channel control assembly 30, and the outlet of the main valve 10 is connected to the remaining flow channels one by one. In this embodiment, the multi-way piece is a three-way piece, and of course it can also be a four-way piece, a five-way piece or other types of multi-way pieces.

[0048] It is also understandable that Figure 2 The schematic diagram of the assembly relationship between the main valve body, the multi-way piece and the one-way valve provided in the embodiment of the present application is illustrated. Figure 3 The exploded schematic diagram of the main valve body, the multi-way piece and the one-way valve provided in the embodiment of the present application is illustrated as follows: Figure 2 and Figure 3 As shown, the main valve 10 is suitable for controlling the water circuit. When the refrigeration equipment is powered off and not in use, the main valve 10 can cut off the water source to prevent the risk of flooding the room due to water valve failure. The main valve 10 is a one-inlet and two-outlet valve, that is, the main valve 10 has one inlet and two outlets, and the two outlets are controlled separately by two valve cores inside the valve, that is, one valve core controls one outlet.

[0049] The multi-way piece is a three-way piece, and the interior of the three-way piece has a first flow channel 21, a second flow channel 22 and a third flow channel 23, and the third flow channel 23 is connected to the first flow channel 21 and the second flow channel 22. The exterior of the three-way piece has a first interface, a second interface and a third interface, the first interface of the three-way piece is connected to the first flow channel 21 and the first outlet of the main valve 10, the second interface of the three-way piece is connected to the second flow channel 22 and the second outlet of the main valve 10, and the third connection port of the three-way piece is connected to the third flow channel 23 and the inlet of the waterway control component 30.

[0050] In this embodiment, the first flow channel 21, the second flow channel 22 and the third flow channel 23 are perpendicular to each other, that is, the first flow channel 21 is perpendicular to the second flow channel 22, the second flow channel 22 is perpendicular to the third flow channel 23, the third flow channel 23 is perpendicular to the first flow channel 21, any two of the first flow channel 21, the second flow channel 22 and the third flow channel 23 are in the same plane, and the remaining flow channel is perpendicular to the plane. Of course, the positional relationship of the three flow channels is not limited to this, and the first flow channel 21, the second flow channel 22 and the third flow channel 23 can also be in the same plane, and the angle between the two adjacent flow channels is equal, that is, the angle between the two adjacent flow channels is 120°, and the three-way piece is a Y-shaped connecting piece.

[0051] It should be noted here that the perpendicularity between the flow channels means that the central axes of the flow channels are perpendicular to the central axes of the flow channels, and the angle between the flow channels means the angle between the central axes of the flow channels.

[0052] It can also be understood that, in order to facilitate the connection between the connection port of the three-way piece and the outlet of the main valve 10, the connection port of the three-way piece is provided with a first mark, and the outlet of the main valve 10 is provided with a second mark, and the first mark corresponds to the second mark one by one. When the first mark and the second mark are both numbers, the corresponding relationship between the first mark and the second mark is that the first mark and the second mark are the same number. For example, the first mark of the second interface of the three-way piece is 2, and the second mark of the second outlet of the main valve 10 is also 2. During the installation process, the staff can connect the second interface of the three-way piece with the second outlet of the main valve 10 according to the corresponding relationship between the first mark and the second mark. Adopting such an assembly method avoids incorrect assembly, effectively shortens the assembly time, and improves work efficiency.

[0053] It should be noted here that the first identifier and the second identifier are not only numbers but also letters. Letters can also play the same role. For example, the first identifier of the second interface of the tee is A, and the second identifier of the second outlet of the main valve is also A; or the first identifier of the second interface of the tee is A, and the second identifier of the second outlet of the main valve is a; or the first identifier of the second interface of the tee is A', and the second identifier of the second outlet of the main valve is A.

[0054] It can also be understood that, since the water output from the first outlet passes through the first flow channel 21, and the water output from the second outlet passes through the second flow channel 22, in order to meet different water needs, the cross-sectional area of ​​the first flow channel 21 can be different from the cross-sectional area of ​​the second flow channel 22, and the size of the flow channel cross-sectional area is specifically determined according to the water consumption corresponding to the flow channel. The flow channel corresponding to the larger water consumption has the larger cross-sectional area. Further, when the cross-sectional area of ​​the first flow channel 21 is different from the cross-sectional area of ​​the second flow channel 22, the cross-sectional area of ​​the third flow channel 23 is the same as the one with the largest cross-sectional area of ​​the first flow channel 21 and the second flow channel 22.

[0055] It is also understandable that Figure 3 As shown, the first outlet of the main valve 10 and the second outlet of the main valve 10 are arranged side by side, and the inlet of the main valve 10 and the first outlet of the main valve 10 and the second outlet of the main valve 10 face the same direction. Since the space inside the refrigeration equipment where the main valve 10 is installed is small, if the various interfaces face different directions, they need to be installed from different angles, which is not only cumbersome to install, but also occupies more space, increases the volume of the refrigeration equipment, and reduces the space utilization rate of the refrigeration equipment. By making the inlet of the main valve 10 and the first outlet of the main valve 10 and the second outlet of the main valve 10 face the same direction, during installation, the staff only needs to connect the pipeline to the various interfaces of the main valve 10 in sequence, and there is no need to change the direction during the installation process, which simplifies the installation process, shortens the installation time, and improves work efficiency.

[0056] It is also understandable that Figure 1 As shown, in order to facilitate the installation of the main valve 10, the main valve 10 is arranged on the mounting seat. The mounting seat is made of metal, the interior of the mounting seat is hollow, and the main valve 10 is located inside the mounting seat. Such an installation method not only plays a fixing role, but also protects the main valve 10. The mounting seat is provided with a connecting part, which is connected to the refrigeration equipment through a fastener. In this embodiment, the fastener is a screw; of course, the fastener can also be a buckle.

[0057] It can also be understood that the water connection assembly 20 further includes a one-way valve 24, the inlet of the one-way valve 24 is connected to the third flow channel 23, and the outlet of the one-way valve 24 is connected to the inlet of the water control assembly 30. The purpose of providing the one-way valve 24 is to prevent water from flowing back to the inside of the three-way piece after flowing out from the third interface of the three-way piece.

[0058] It is also understandable that Figure 3As shown, in order to facilitate the installation of the one-way valve 24, a quick connector is provided at the inlet of the one-way valve 24, and an annular groove is provided on the outer peripheral surface of the third interface of the three-way piece. The tongue of the quick connector is clamped in the annular groove to achieve a quick connection between the inlet of the one-way valve 24 and the third interface of the three-way piece, thereby shortening the assembly time and improving the installation efficiency. The outlet of the one-way valve 24 is connected to the inlet of the waterway control assembly 30 through a water outlet pipe, which is a flexible pipe. Specifically, the material of the water outlet pipe can be plastic, rubber, silicone or other materials.

[0059] In order to simplify the connection between the outlet of the one-way valve 24 and the water outlet pipe, the water outlet pipe is sleeved with a hard pipe, and the hard pipe is plug-connected to the outlet of the one-way valve 24 and sealed by a sealing ring; or, the outlet of the one-way valve 24 is provided with a quick connector, and the outer periphery of the hard pipe is provided with an annular groove, and the tongue of the quick connector is clamped in the annular groove to achieve a quick connection between the outlet of the one-way valve 24 and the water outlet pipe; or the water outlet pipe is directly sleeved on the outlet of the one-way valve 24 and fixed by a clamp to prevent water leakage.

[0060] It is also understandable that Figure 3 As shown, the first outlet of the main valve 10 and the second outlet of the main valve 10 are arranged side by side, and the first flow channel 21 is perpendicular to the second flow channel 22. When the second interface is connected to the second outlet of the main valve 10, since the first interface of the three-way piece and the first outlet of the main valve 10 are not in the same direction, the first flow channel 21 is connected to the first outlet of the main valve 10 through the steering joint 25, that is, the first interface is connected to the first outlet of the main valve 10 through the steering joint 25. The steering joint 25 is an L-shaped pipeline component, and of course it can also be a C-shaped or other shapes of steering joints 25, which is specifically determined according to the positional relationship between the first interface and the first outlet. The present application can facilitate the connection of the first interface and the first outlet in different directions by adopting a steering structure.

[0061] It is also understandable that Figure 3 As shown, in order to facilitate the connection between the steering joint 25 and the first flow channel 21, the steering joint 25 and the first flow channel 21 are connected through a quick connector. Specifically, a quick connector is provided at one end of the steering joint 25, and an annular groove is provided on the outer peripheral surface of the first flow channel 21, that is, an annular groove is provided on the outer peripheral surface of the first interface; or, an annular groove is provided on the outer peripheral surface of one end of the steering joint 25, and a quick connector is provided on the first interface, and the tongue of the quick connector is clamped in the annular groove. Similarly, in order to facilitate the connection between the steering joint 25 and the first outlet of the main valve 10, the steering joint 25 and the first outlet of the main valve 10 can also be connected through a quick connector.

[0062] It can also be understood that the number of outlets of the main valve 10 is greater than or equal to the number of flow channels, so that there will be surplus outlets of the main valve 10, and only some outlets are connected to the flow channels for use, and the remaining outlets are usually idle for use in subsequent functional expansion, or when part of the valve core is damaged, the spare outlet is activated for replacement. For example, when the main valve 10 has three outlets, the first interface is connected to one interface of the main valve 10, the second interface is connected to another interface of the main valve 10, and the remaining interface is idle for use in subsequent functional expansion. The number of outlets of the main valve 10 is determined specifically according to the water demand and the waterway control method.

[0063] Figure 4 The schematic diagram of the principle of the piping device of the refrigeration equipment provided in the embodiment of the present application is illustrated as follows: Figure 4 As shown, the water circuit control mode is determined by the number of water demand types and the number of outlets of the main valve 10. For example, when the main valve 10 is a one-inlet and two-outlet valve, and the water demand is divided into freezing ice-making water, refrigerated ice-making water and drinking water, since the main valve 10 has only two valve cores, it is impossible to realize that one valve core controls one water use mode alone. At this time, one valve core can control one water use mode, and the other valve core can control the other two water use modes, for example, one valve core controls freezing ice-making water, and the other valve core controls refrigerated ice-making water and drinking water; or one valve core controls refrigerated ice-making water, and the other valve core controls freezing ice-making water and drinking water; or one valve core controls drinking water, and the other valve core controls refrigerated ice-making water and freezing ice-making water.

[0064] It can also be understood that the water circuit control component 30 has multiple inlets, that is, the filter element 31 is provided with multiple inlets, the multiple inlets of the filter element 31 are interconnected, the water circuit connection component 20 includes multiple connecting pipes, each connecting pipe has a flow channel inside, and the inlet of the water circuit control component 30 is connected to the outlet of the main valve 10 one-to-one through the connecting pipe. By providing multiple inlets in the filter element 31, and connecting the inlet of the water circuit control component 30 to the outlet of the main valve 10 one-to-one through the connecting pipe, the connection effect of a three-way piece can also be achieved. For example, the filter element 31 is provided with two inlets, the main valve 10 is a one-inlet and two-outlet valve, and the two outlets of the main valve 10 are connected to the two inlets of the filter element 31 one-to-one through the connecting pipe.

[0065] It can also be understood that one end of the connecting pipe is connected to the inlet of the water circuit control assembly 30 through a quick connector, and the other end of the connecting pipe is connected to the outlet of the main valve 10 through a quick connector. By using a quick connector to install the connecting pipe, the installation process of the connecting pipe can be effectively simplified and the production efficiency can be improved.

[0066] It is also understandable that Figure 1As shown, the water circuit control assembly 30 includes a filter element 31 and a post-valve 32, and at least two flow channels are connected to the inlet of the filter element 31. Specifically, the inlet of the filter element 31 is connected to the outlet of the one-way valve 24. Since the existing filter element 31 pursues smaller and smaller volume, in order not to increase the volume of the filter element 31, the filter element 31 only needs to be provided with one inlet and one outlet, and the inlet and outlet of the filter element 31 are arranged symmetrically. The inlet of the post-valve 32 is connected to the outlet of the filter element 31, and the post-valve 32 is also a one-inlet and multiple-outlet valve. The number of outlets of the post-valve 32 is specifically determined according to the water demand. In this embodiment, the water demand is mainly divided into three types, namely, water for freezing ice making, water for refrigerating ice making, and water for drinking.

[0067] It is also understandable that Figure 1 As shown, the rear valve 32 is a one-inlet and three-outlet valve, the first outlet of the rear valve 32 is connected to the freezing ice-making pipeline 33, the second outlet of the rear valve 32 is connected to the refrigeration ice-making pipeline 34, and the third outlet of the one-inlet and three-outlet valve is connected to the drinking water pipeline 35, and the drinking water pipeline is provided with a dispenser.

[0068] A specific embodiment of the present application is described below. The piping device of the refrigeration equipment includes a main valve 10, a water circuit connection assembly 20 and a water circuit control assembly 30. The inlet of the main valve 10 is connected to a water inlet pipe, and the water inlet pipe is connected to a water source. The main valve 10 is a one-inlet and multiple-outlet valve. The first outlet of the main valve 10 and the second outlet of the main valve 10 are arranged side by side, and the inlet of the main valve 10 and the first outlet of the main valve 10 and the second outlet of the main valve 10 face the same direction.

[0069] The water channel connection assembly 20 includes a three-way piece and a one-way valve 24. The interior of the three-way piece has a first flow channel 21, a second flow channel 22 and a third flow channel 23.
