[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For example, "fixation" can be a fixed 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 elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0030] The utility model proposes a waterway structure, referring to Figure 1 The water channel structure 100 is applied to a heat pump device, which can be a drying equipment, such as a heat pump dryer, a packaging heat pump dryer, a water-based ink printing heat pump drying, a wood drying heat pump equipment, a fruit and vegetable drying equipment, a grain drying heat pump equipment, a tobacco leaf or a pepper drying heat pump equipment, etc. The heat pump device can also be other heat pump equipment with a water channel system, which will not be introduced in detail here.

[0031] Reference Figures 1 to 4 The waterway structure 100 includes a waterway component 1 and a protective component 2. The waterway component 1 is used to transport liquid, and the protective component 2 includes a first protective member 21 and a second protective member 22. The first protective member 21 and the second protective member 22 are detachably connected, and the first protective member 21 and the second protective member 22 are used to wrap the outside of the waterway component 1 together.

[0032] Based on the above-mentioned scheme, the first protective member 21 and the second protective member 22 are used to wrap the outside of the water channel assembly 1. Such a configuration can not only protect the water channel assembly 1, so that the water channel assembly 1 can be kept warm, but also effectively avoid the water channel assembly 1 from colliding with other components of the unit and causing damage to the water channel assembly 1, thereby improving the insulation effect and operating efficiency of the water channel, and can also prevent water from splashing onto other components of the unit when the water channel assembly 1 is damaged and leaks, so as to better protect the internal components of the unit, improve the safety performance of the unit operation, and improve the reliability of the heat pump unit.

[0033] In addition, the first protective member 21 and the second protective member 22 can also seal the various connections of the water channel assembly 1, thereby improving the conveying effect of the water channel assembly 1, reducing water leakage of the water channel assembly 1, and better improving the protective effect of the water channel structure 100.

[0034] The first protective member 21 and the second protective member 22 can be connected by snapping, for example, a plurality of snap protrusions are provided on a side of the first protective member 21 facing the second protective member 22, and a plurality of snap grooves are provided on a side of the second protective member 22 facing the first protective member 21, and the plurality of snap protrusions and the plurality of snap grooves are arranged in one-to-one correspondence, and each snap protrusion is snap-fitted with each snap groove to fix the first protective member 21 and the second protective member 22.

[0035] It is understandable that a plurality of slots may be provided on the side of the first protective member 21 facing the second protective member 22, and a plurality of buckle protrusions may be provided on the side of the first protective member 21 facing the second protective member 22, and the plurality of buckle protrusions are buckled in one-to-one correspondence with the plurality of slots.

[0036] The first protective member 21 and the second protective member 22 may also be connected by screw fixing, or by other fixing methods, which are not listed here one by one.

[0037] The liquid transported by the water channel assembly 1 may be water, a mixed liquid, or other liquids. In the technical solution of the present application, the liquid transported by the water channel assembly 1 is water, which is only an example and not a limitation.

[0038] Reference Figures 1 to 4 The first protective member 21 and the second protective member 22 are enclosed together to form a receiving hole 23. The waterway assembly 1 includes an exhaust member 12, which is arranged in the receiving hole 23. The exhaust end of the exhaust member 12 extends out of the receiving hole 23. The exhaust member 12 is used to discharge the gas in the pipeline out of the waterway system. The waterway structure 100 also includes a waterproof member 3, which is sleeved on the exhaust end of the exhaust member 12 and guides the liquid or gas discharged by the exhaust member 12.

[0039] When the fluorine system leaks inside the heat pump system, the refrigerant gas will mix into the pipeline, and the exhaust component 12 can discharge the refrigerant gas in the pipeline out of the water system to ensure the safe operation of the heat pump unit. If the exhaust component 12 fails and cannot work normally, that is, when the exhaust component 12 fails, the exhaust component 12 will discharge the refrigerant gas outwards and also splash the water in the water system outwards, which may easily cause damage to important components inside the unit and affect the performance of the heat pump unit.

[0040] The waterproof component 3 can not only protect the exhaust component 12, so that when the exhaust component 12 discharges gas, the gas can be diverted to ensure the smoothness of the exhaust of gas from the exhaust component 12 and the exhaust effect, but also can divert the water and gas discharged by the exhaust component 12 when the exhaust component 12 fails, so that the water and gas discharged by the exhaust component 12 are sprayed in a direction avoiding the internal circuit components of the unit, so as to avoid the important components inside the unit, thereby achieving the effect of protecting the important components of the unit when the exhaust component 12 fails, thereby improving the protection effect of the water channel structure 100.

[0041] Continue to refer to Figures 1 to 4 The waterproof member 3 is provided with a receiving groove 31, and the exhaust end of the exhaust member 12 is provided in the receiving groove 31. The waterproof member 3 is also provided with a guide hole 32 connected with the receiving groove 31, and the guide hole 32 is arranged away from the notch of the receiving groove 31. The guide hole 32 can guide the flow of gas discharged from the exhaust member 12 in the receiving groove 31 to avoid the circuit components inside the unit, thereby ensuring the safe operation inside the unit.

[0042] It is understandable that the waterproof component 3 can also be externally connected to a guide pipe, which is connected to the guide hole 32. The guide pipe is used to extend the guide stroke to better guide the gas or liquid discharged from the exhaust component 12, more effectively avoid the influence of water on the internal circuit components of the unit, and enhance the protection effect of the water channel structure 100.

[0043] In actual use, the position angle and direction of the guide hole 32 can be adjusted according to the distribution of the internal structure of the unit to ensure that the gas and liquid discharged by the exhaust member 12 will not splash onto the internal electronic components of the unit to ensure the safe operation of the unit.

[0044] The exhaust component 12 may be an exhaust valve, such as a microbubble exhaust valve, etc. The exhaust component 12 may also be other structural components with exhaust functions, which are not specifically limited here.

[0045] Continue to refer to Figures 1 to 4 The waterproof member 3 is provided with a crimping portion 33, which is crimped and matched with the hole wall of the receiving hole 23 to fix the waterproof member 3. The crimping portion 33 can be arranged near the notch of the receiving slot 31, or can be arranged at the middle of the waterproof member 3 along its own length direction. In the embodiment of the present application, the crimping portion 33 is arranged near the notch of the receiving slot 31 as an example, which is only an example and not limited.

[0046] With such arrangement, the waterproof component 3 can be fixed by the crimping cooperation between the crimping portion 33 and the hole wall of the accommodating hole 23, and the installation method is simple, the disassembly and assembly are convenient, and the subsequent maintenance is also convenient.

[0047] In addition, the crimping portion 33 can also seal the notch of the accommodating groove body 31, reduce the gap between the waterproof component 3 and the exhaust component 12, effectively prevent the gas exhausted by the exhaust component 12 from leaking, and make the gas be discharged from the guide hole 32 in a concentrated manner, thereby improving the exhaust effect.

[0048] It can be understood that the crimping portion 33 can be a crimping flange, which is extended along the circumferential direction of the waterproof component 3. The crimping flange is distributed on the edge of the slot of the accommodating slot body 31. The hole wall of the accommodating hole 23 is provided with a crimping groove, which is extended along the circumferential direction of the accommodating hole 23. That is, a part of the crimping groove is formed on the first protective component 21, and the other part is formed on the second protective component 22. The crimping flange extends into the crimping groove to press and fix the waterproof component 3 when the first protective component 21 and the second protective component 22 are fixed together.

[0049] The crimping portion 33 may also be an annular convex edge or other structural components that are connected to and cooperate with the protective component and fix the waterproof component 3, which are not listed here one by one.

[0050] The waterproof part 3 is a flexible structure, and the waterproof part 3 can be a flexible rubber sleeve or a flexible silicone sleeve so that the waterproof part 3 has good flexibility as a whole. It is arranged in this way to facilitate maintenance personnel to operate the exhaust part 12 through the waterproof part 3 during the later maintenance process, such as twisting operations such as opening or closing, which greatly improves the operating performance of the waterway structure 100.

[0051] Continue to refer to Figures 1 to 4 The water circuit assembly 1 includes a first pipeline 11, an exhaust member 12, a second pipeline 13, a pressure relief member 14, a water pump 15 and a third pipeline 16. The first pipeline 11, the exhaust member 12, the second pipeline 13, the pressure relief member 14, the water pump 15 and the third pipeline 16 are arranged in series and connected in sequence.

[0052] Water can be transported through the first pipeline 11, the exhaust member 12, the second pipeline 13, the pressure relief member 14, the water pump 15 and the third pipeline 16. It can be understood that the connection positions between the first pipeline 11, the exhaust member 12, the second pipeline 13, the pressure relief member 14, the water pump 15 and the third pipeline 16 are all sealed.

[0053] The pressure relief component 14 may be a pressure relief valve or other structural components with a pressure relief function, which is not specifically limited herein.

[0054] The first protective member 21 and the second protective member 22 can fully wrap the water circuit assembly 1, that is, wrap the first pipeline 11, the exhaust member 12, the second pipeline 13, the pressure relief member 14, the water pump 15 and the third pipeline 16, so as to keep the first pipeline 11, the exhaust member 12, the second pipeline 13, the pressure relief member 14, the water pump 15 and the third pipeline 16 warm, and effectively prevent the water in the first pipeline 11, the second pipeline 13 and the third pipeline 16 from freezing; on the other hand, the first protective member 21 and the second protective member 22 can seal the first pipeline 11, the second pipeline 13 and the third pipeline 16 to achieve a waterproof effect.

[0055] Among them, the first protective member 21 and the second protective member 22 are both made of EPP material, that is, polypropylene foam material (Expanded Polypropylene). The EPP material has good thermal insulation performance, so that the first protective member 21 and the second protective member 22 can well insulate the first pipeline 11, the second pipeline 13 and the third pipeline 16.

[0056] It can be understood that the first protective member 21 and the second protective member 22 can both be insulation shells. The first protective member 21 and the second protective member 22 can also be other shell components with insulation properties, as long as they can be compatible with the external contour shape of the first pipeline 11, the exhaust member 12, the second pipeline 13, the pressure relief member 14, the water pump 15 and the third pipeline 16, and no specific limitation is made here.

[0057] Continue to refer to Figures 1 to 4 The first protective member 21 and the second protective member 22 are enclosed together to form a first protective cavity 24. The exhaust member 12 has a first joint 121 and a second joint 122, and the first joint 121 and the second joint 122 are both arranged in the first protective cavity 24. One end of the first pipeline 11 is connected to the external water system, and the other end is connected to the first joint 121. One end of the second pipeline 13 is connected to the second joint 122.

[0058] Such arrangement, on the one hand, can insulate the first pipeline 11 and the exhaust component 12 to effectively avoid the phenomenon of pipeline blockage caused by water freezing in cold weather, which effectively saves the operation of insulation by wrapping with cotton and improves production efficiency. On the other hand, it can also protect the first pipeline 11 and the exhaust component 12, reduce the possibility of the first pipeline 11 and the exhaust component 12 being damaged by foreign objects, and can also block the leaking water flow when damage and water leakage occur at the interface between the first pipeline 11 and the exhaust component 12, effectively preventing water from splashing onto the circuit components inside the unit, so as to protect the unit.

[0059] In addition, the first protective cavity 24 provides an accommodation space for the connection between the first pipeline 11 and the second pipeline 13 and the exhaust component 12 respectively, so that the protective component 2 is not affected by the connection structure between the first pipeline 11 and the second pipeline 13 and the exhaust component 12 respectively, so that the outside of the water channel component 1 can be fully wrapped, thereby improving the protective performance of the protective component 2.

[0060] Among them, the first pipeline 11 can be threadedly connected to the first joint 121 through a nut to fix the first pipeline 11 and the first joint 121. The second pipeline 13 is threadedly connected to the second joint 122 through a nut to fix the second pipeline 13 and the second joint 122. The connection between the first pipeline 11 and the first joint 121, and the second pipeline 13 and the second joint 122 is sealed. The first pipeline 11 and the first joint 121, and the second pipeline 13 and the second joint 122 can also be connected by buckling, and the first pipeline 11 and the first joint 121, and the second pipeline 13 and the second joint 122 can also be connected by other fixing methods, as long as the connection between the first pipeline 11 and the first joint 121, and the second pipeline 13 and the second joint 122 is sealed.

[0061] Continue to refer to Figures 1 to 4 The first protective member 21 and the second protective member 22 cooperate to form an avoidance gap 25 and an operating port 26. The avoidance gap 25 is connected to the operating port 26. The air release end 141 of the pressure relief member 14 extends out of the protective assembly 2 from the avoidance gap 25, and the operating part 142 of the pressure relief member 14 is exposed from the operating port 26.

[0062] With such arrangement, under the premise of not affecting the operation of the pressure relief member 14 , the air release end 141 of the pressure relief member 14 can release air to the outside normally by avoiding the gap, and the operation port 142 provides convenience for the operator to turn the operation part 12 .

[0063] In addition, on the one hand, the second pipeline 13 and the pressure relief component 14 can be insulated to effectively avoid the phenomenon of pipeline blockage caused by water freezing in cold weather, which effectively saves the operation of insulation by wrapping cotton and improves production efficiency. On the other hand, it can also protect the second pipeline 13 and the pressure relief component 14, reduce the possibility of the second pipeline 13 and the pressure relief component 14 being damaged by foreign objects, and can also block the leaking water flow when damage and water leakage occur at the interface between the second pipeline 13 and the pressure relief component 14, effectively preventing water from splashing onto the circuit components inside the unit, so as to protect the unit.

[0064] Continue to refer to Figures 1 to 4The first protective member 21 and the second protective member 22 are enclosed together to form a second protective cavity 27. The water pump 15 has a first connecting pipe 151 and a second connecting pipe 152. The first connecting pipe 151 and the second connecting pipe 152 are both arranged in the second protective cavity 27. One end of the second pipeline 13 away from the exhaust member 12 is connected to the first connecting pipe 151, one end of the third pipeline 16 is connected to the second connecting pipe 152, and the other end is connected to the external water system. The second protective cavity 27 is connected to the first protective cavity 24.

[0065] Such arrangement, on the one hand, can insulate the water pump 15 and the third pipeline 16 to effectively avoid the phenomenon of pipeline blockage caused by water freezing in cold weather, which effectively saves the operation of insulation by wrapping with cotton and improves production efficiency. On the other hand, it can also protect the water pump 15 and the third pipeline 16, reduce the possibility of the water pump 15 and the third pipeline 16 being damaged by foreign objects, and can also block the leaking water flow when damage and water leakage occur at the interface between the water pump 15 and the third pipeline 16, effectively preventing water from splashing onto the circuit components inside the unit, so as to protect the unit.

[0066] In addition, the second protective cavity 27 provides an accommodation space for the connection between the second pipeline 13 and the third pipeline 16 and the water pump 15 respectively, so that the protective component 2 is not affected by the connection structure between the second pipeline 13 and the third pipeline 16 and the water pump 15 respectively. In this way, the outside of the water circuit component 1 can be fully wrapped, thereby improving the protective performance of the protective component 2.

[0067] Among them, the second pipeline 13 can be threadedly connected to the first connecting pipe 151 through a nut to fix the second pipeline 13 and the first connecting pipe 151. The third pipeline 16 is threadedly connected to the second connecting pipe 152 through a nut to fix the third pipeline 16 and the second connecting pipe 152. The connection between the second pipeline 13 and the first connecting pipe 151, and the third pipeline 16 and the second connecting pipe 152 is sealed. The second pipeline 13 and the first connecting pipe 151, and the third pipeline 16 and the second connecting pipe 152 can also be connected by buckling, and the second pipeline 13 and the first connecting pipe 151, and the third pipeline 16 and the second connecting pipe 152 can also be connected by other fixing methods, as long as the connection between the second pipeline 13 and the first connecting pipe 151, and the third pipeline 16 and the second connecting pipe 152 is sealed.
