Description

Technical Field

[0001] This application relates to the technical field of control boxes, and in particular to an anti-condensation stator. Background Technology

[0002] The control box of a water pump typically operates in a high humidity and low temperature environment. Due to the high temperature inside the control box, the water vapor inside the control box will have its heat absorbed by the metal screws and liquefy into water vapor. Since the screws are connected to the stator, the stator's cold water circulation system will further absorb the heat of the water vapor, causing condensation to form inside the control box. Utility Model Content

[0003] To address the shortcomings of existing technologies, one of the objectives of this application is to provide an anti-condensation stator, which has the advantage of having a metal fastener that is directly connected to the stator without passing through the inside of the housing. This reduces the probability that the water and heat vapor generated by the control components inside the housing in a high-humidity and high-temperature environment will liquefy and form condensate through the fastener (cold water circulates inside the stator, and the fastener is locked to the stator by threads; the overall temperature is low).

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] An anti-condensation stator includes a housing and a stator. The housing is provided with a connecting part and a fixing part. The fixing part connects the housing and the stator through the connecting part. The connecting part is not in communication with the inside of the housing.

[0006] By adopting the above technical solution, the connecting part is not connected to the inside of the box, so that the fixing part is directly connected to the stator without passing through the inside of the box. This reduces the heat transferred from the box to the stator and lowers the probability that the water and heat vapor generated by the control elements inside the box in a high humidity and heat environment will liquefy and form condensate through the fixing part (cold water circulates inside the stator, and the fixing part locks the stator with threads; the overall temperature is low).

[0007] In a preferred embodiment, this application may be further configured such that: the connecting part 1 includes a through hole 1 and a through hole 2, the through hole 1 and the through hole 2 for the fastener 1 to pass through.

[0008] In a preferred embodiment, the present application may be further configured such that: the housing includes an upper cover and a lower cover, the lower cover is in contact with the stator, and a seal is provided between the upper cover and the lower cover.

[0009] By adopting the above technical solution, the sealing component makes the box body more airtight.

[0010] In a preferred embodiment, this application can be further configured such that: the upper cover is provided with a connecting part two and a fixing member two, and the fixing member two mounts the circuit board on the upper cover through the connecting part two.

[0011] In a preferred embodiment, this application may be further configured such that: the upper cover is provided with a through hole three and a fastener three, the fastener three connecting the upper cover and the lower cover through the through hole three.

[0012] By adopting the above technical solution, the fixing component three connects the upper cover and the lower cover through the through hole three, and does not contact the stator, thereby reducing the heat transfer between the stator and the housing.

[0013] In a preferred embodiment, this application may be further configured such that: a grounding fixing member is provided on the circuit board, the grounding fixing member is used to connect to a grounding wire, and one end of the fixing member away from the stator is connected to the grounding wire through the grounding fixing member.

[0014] By adopting the above technical solution, the end of the fixing component away from the stator is connected to the grounding fixing component and the grounding wire, so that the stator can be grounded without direct contact with the grounding fixing component.

[0015] In a preferred embodiment, this application may be further configured such that the stator has a boss, which defines the relative position of the stator and the housing.

[0016] By adopting the above technical solution, the boss defines the relative position of the stator and the housing, so that there is a gap between the stator and the housing, thereby reducing the contact area between the stator housing and the housing.

[0017] In a preferred embodiment, this application may be further configured such that the stator is provided with a contact element for isolating the housing and the stator and reducing vibration between the housing and the stator.

[0018] By adopting the above technical solution, the contact components reduce the vibration between the housing and the stator, making the housing and the stator more stable during operation. Attached Figure Description

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1 to 5 The present application discloses an anti-condensation stator, which includes a housing 1, a circuit board 2 and a stator 3. The housing 1 includes an upper cover 4 and a lower cover 5. A sealing element 6 is provided between the upper cover 4 and the lower cover 5. In this embodiment, the sealing element 6 can be made of flexible materials such as rubber or silicone. The shape of the sealing element 6 can be designed as needed to improve the sealing between the upper cover 4 and the lower cover 5.

[0027] The box body 1 is provided with a connecting part 11, a fixing part 12, a connecting part 2 13, a fixing part 2 14, a through hole 3 15 and a fixing part 3 16. The connecting part 2 13 and the through hole 3 15 are provided on the upper cover 4, and the lower cover 5 is provided with a threaded hole that matches the through hole 3 15.

[0028] Connecting part 11 is provided on both sides of the box body 1. Fixing part 12 connects the box body 1 and the stator 3 through connecting part 11. Connecting part 11 includes through hole 17 and through hole 28. Through hole 17 is provided on the upper cover 4 and through hole 28 is provided on the lower cover 5. Through hole 17 and through hole 28 allow fixing part 12 to pass through and are not connected to the inside of the box body 1. Connecting part 213 is provided with threaded holes that cooperate with fixing part 214. Fixing part 214 installs circuit board 2 on the box body 1 through connecting part 213. There are four sets of through holes 315, which are evenly distributed on the box body 1. Fixing part 316 connects the upper cover 4 and the lower cover 5 through through holes 315.

[0029] The circuit board 2 is provided with a grounding fixing component 21. The grounding fixing component 21 is installed on the upper cover 4 and connected to the fixing component 12. The upper cover 4 is provided with a threaded hole that matches the grounding fixing component 21. The grounding fixing component 21 is used to connect to the grounding wire.

[0030] The stator 3 is provided with a boss 7 and a contact 8. The boss 7 is used to define the relative position of the stator 3 and the housing 1. The boss 7 is provided with a threaded hole connected to the fixing member 12. The contact 8 is used to isolate the housing 1 and the stator 3 and reduce the vibration between the housing 1 and the stator 3. In this embodiment, the number of bosses 7 and contact 8 is set to two sets and symmetrically arranged on the stator 3. The contact 8 can be made of flexible materials such as rubber or silicone, so that the contact 8 can play a certain role in heat insulation for the housing 1.

[0031] In this embodiment, the fixing member 12, fixing member 24, fixing member 316 and grounding fixing member 21 can be screws.

[0032] When connecting circuit board 2, the second fixing member 14 passes through circuit board 2 and connects to the second connecting part 13. The grounding fixing member 21 is installed on circuit board 2 and connected to the grounding wire.

[0033] When installing the upper cover 4 and the lower cover 5, first install the sealing element 6 on the upper cover 4. The fixing element 12 passes through the upper cover 4 and connects to the lead wire of the grounding fixing element 21. The lead wire can be a cable. For ease of description, the lead wire is not shown in the figure. Then, cover the lower cover 5 with the upper cover 4. Then, thread the fixing element 16 through the upper cover 4 and connect it to the connecting part 3, so that the upper cover 4 and the lower cover 5 are installed tightly. Let the fixing element 12 pass through the through hole on the lower cover 5. Rotate the fixing element 12 to fix the housing 1 and the stator 3. The boss 7 contacts the housing 1, reducing the contact area between the stator 3 housing and the housing 1. The contact element 8 abuts against the housing 1, reducing the vibration between the housing 1 and the stator 3 and isolating the housing 1 and the stator 3.

[0034] The implementation principle of this embodiment is as follows: the connecting part 11 is not connected to the inside of the box 1, so that the fixing part 12 is directly connected to the stator 3 without passing through the inside of the box 1, which reduces the heat transferred from the control box to the stator 3, thereby reducing the probability of condensation inside the box 1. Since the upper cover 4 and the stator 3 do not contact each other, the fixing part 14 and the grounding fixing part 21 installed on the upper cover 4 do not contact the stator 3, further reducing the probability of heat transferred from the box 1 to the stator 3.

[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
