Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a water level monitoring device and water treatment equipment. Background Technology

[0002] The water level sensor is a connector type to detect the water level in the water tank. The upper and lower water levels in the tank determine the upper and lower positions of the float inside. That is, the higher the water tank, the longer the connector type water level sensor. Common extra-long (greater than 180mm) connector type water level sensors are usually split into two parts and then connected in the middle by a pipe. The increase in connection points brings problems such as water leakage and insufficient overall strength. Utility Model Content

[0003] To address the problems of increased leakage risk and insufficient overall strength caused by numerous connection points in existing technologies, this utility model provides a water level monitoring device and water treatment equipment.

[0004] The water level monitoring device provided in this application is used to monitor the water level in a water tank of a water treatment device, including a water level monitor, a first sensing device, and a second sensing device. The water level monitor has a first communication structure for connecting to the water tank, and has a first cavity and a second cavity respectively arranged vertically and communicating with each other. A float is provided in both the first cavity and the second cavity, and a limiting structure is provided between the first cavity and the second cavity to restrict the passage of the float. The first sensing device and the second sensing device are both connected to the water level monitor and are respectively close to but not connected to the first cavity and the second cavity, so as to sense the float in the first cavity and the second cavity.

[0005] In some embodiments, the water level monitor is an integral tubular structure with a cavity; The water level monitor includes a first end, a second end, and a middle part located between the first end and the second end. The first end is used to connect to the water tank, and the second end is connected to the external environment. The middle part is provided with the limiting structure, which extends radially along the water level monitor to divide the tube into a first cavity near the first end and a second cavity near the second end and communicating with the first cavity.

[0006] In some embodiments, the middle portion has a side hole; The water level monitoring device further includes a limiting member, which includes a first sealing part and a first limiting part connected to the first sealing part. The first sealing part covers the side hole and is sealed to the edge of the side hole. The first limiting part extends a predetermined distance radially toward the cavity of the tubular structure to form the limiting structure.

[0007] In some embodiments, the first end has a first port, and the second end has a second port; The water level monitoring device also includes a cover for sealing the first port, and the second port is used to connect to the water tank; A pressure balance port is provided on the side of the first end along a direction perpendicular to the axial direction of the tubular structure, and the pressure balance port is used to connect to the interior of the ice-making chamber.

[0008] In some embodiments, the first sensing device and the second sensing device are respectively disposed on the outer surfaces of the first end and the second end; The cover includes a second sealing part and a second limiting part connected to the second sealing part. The second sealing part is disposed on the first port and is sealed to the edge of the first port. The second limiting part extends a predetermined distance toward the cavity along the axial direction of the tubular structure. The floats in the first cavity and the second cavity are respectively a first float and a second float. As the first float gradually approaches the first sensing device, when the first float first senses the first sensing device, the first float abuts against the second limiting part.

[0009] In some embodiments, the cover member has the same structure as the limiting member.

[0010] In some embodiments, a third limiting part is provided on the inner wall of the cavity near the second port. As the second float gradually approaches the second sensing device, when the float first senses the second sensing device, the second float abuts against the third limiting part.

[0011] In some embodiments, the tube wall of the middle portion is recessed inward to a predetermined depth to form the limiting structure.

[0012] The water treatment equipment provided in this application includes a water tank and the aforementioned water level monitoring device, wherein the first connecting structure is connected to the water tank.

[0013] In some embodiments, the water treatment equipment further includes an ice-making chamber, which is semi-enclosed; The water level monitor also has a second communication structure for connecting the interior of the ice-making chamber, the second communication structure being connected to the first cavity.

[0014] Compared with the prior art, the water level monitoring device and water treatment equipment provided by this utility model have the following advantages: the floating path of the float is completely confined inside the water level monitor, and the first sensing device and the second sensing device are both set outside the first cavity and the second cavity, which reduces the connection points on the floating path of the float, reduces the risk of water leakage, and improves the mechanical strength of the entire device.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] like Figure 3 , Figure 4 The illustrated water level monitoring device 100 is used to monitor the water level in a water tank 200 of a water treatment device. It includes a water level monitor 11, a first sensing device 14, and a second sensing device 15. The water level monitor 11 has a first communication structure 04 for connecting to the water tank 200, and has a first cavity 061 and a second cavity 062 respectively arranged vertically and communicating with each other. The top of the first cavity 061 is connected to the first communication structure 04. In this way, the water tank 200 and the water level monitor 11 form a communicating vessel, and the water level in the water tank 200 can be displayed through the water levels in the first cavity 061 and the second cavity 062 of the water level monitor 11.

[0024] Please continue reading. Figure 3 , Figure 4A float 13 is provided in both the first cavity 061 and the second cavity 062, and a limiting structure 12 is provided between the first cavity 061 and the second cavity 062 to restrict the passage of the float 13. The two floats 13 are used to float in the first cavity 061 and the second cavity 062 respectively. It should be noted that the float 13 can float on the water surface. When the water level in the water tank 200 changes, the water level in the water level monitoring device 100 will also change, and the float 13 will float in the first cavity 061 and the second cavity 062 following the water level change of the water level monitoring device 100.

[0025] Please continue reading. Figure 3 , Figure 4 The first sensing device 14 and the second sensing device 15 are both connected to the water level monitor 11 and are respectively close to but not connected to the first cavity 061 and the second cavity 062, so as to sense the float 13 in the first cavity 061 and the second cavity 062. When the float 13 in the first cavity 061 floats to the extreme position near the first end 111 of the first cavity 061, the first sensing device 14 senses the float 13 and sends a first signal; when the float 13 in the second cavity 062 floats to the extreme position near the second end 112, the second sensing device 15 senses the float 13 and sends a second signal. It can be understood that, as Figure 3 Figure 4 As shown, when float 13 floats to the extreme position near the first end 111 of the first cavity 061, the water level in the water level monitoring device 100 reaches its maximum value, corresponding to a full water tank 200; when float 13 floats to the extreme position near the second end 112, the water level in the water level monitoring device 100 reaches its minimum value, corresponding to a low water level in the water tank 200. Therefore, the first signal is used to indicate that the water tank 200 is full, and the second signal is used to indicate that the water tank 200 is low. The above design completely restricts the floating path of float 13 inside the water level monitor 11. The first sensing device 14 and the second sensing device 15 are both located outside the first cavity 061 and the second cavity 062, reducing the connection points on the floating path of float 13, reducing the risk of leakage, and improving the mechanical strength of the entire device.

[0026] It should be added that the aforementioned first sensing device 14 and second sensing device 15 are also electrically connected to the MCU module of the water treatment equipment. The first signal and the second signal emitted by the first sensing device 14 and the second sensing device 15 can both be transmitted to the MCU module, thus indicating whether the water tank 200 is low on water or full. Figure 4As shown, when the float 13 rises with the water level monitoring device 100 until it senses the second sensing device 15, it indicates that the water tank 200 is full. The MCU module receives the second signal and controls the water treatment equipment to send a signal that the water tank 200 is full. When the float 13 falls with the water level monitoring device 100 until it senses the first sensing device 14, it indicates that the water tank 200 is short of water. The MCU module receives the first signal and controls the water treatment equipment to send a signal that the water tank 200 is short of water.

[0027] In some implementations, such as Figure 3 , Figure 4 As shown, the water level monitor 11 is an integrated tubular structure with a cavity 06. It has a simple structure and the integrated tubular structure has a low risk of leakage.

[0028] Please continue reading. Figure 3 , Figure 4 The water level monitor 11 includes a first end 111, a second end 112 and an intermediate part 113 located between the first end 111 and the second end 112. The first end 111 is used to connect to the water tank 200, and the second end 112 is connected to the external environment. A limiting structure 12 is provided in the middle part 113. The limiting structure 12 extends radially along the water level monitor 11 to divide the cavity 06 into a first cavity 061 near the first end 111 and a second cavity 062 near the second end 112 and connected to the first cavity 061. The above design is simple. The float 13 floats inside the cavity 06, and there are no joints on the inner wall of the cavity 06, reducing the risk of leakage. The integrated cavity 06 structure also improves the mechanical strength of the entire device.

[0029] In some implementations, such as Figure 3 , Figure 4 As shown, the middle part 113 has a side hole 1131. The water level monitoring device 100 also includes a limiting member 16, which includes a first sealing part 161 and a first limiting part 162 connected to the first sealing part 161. The first sealing part 161 covers the side hole 1131 and is sealed to the edge of the side hole 1131. The first limiting part 162 extends a predetermined distance radially towards the cavity 06 of the tubular structure to form a limiting structure 12. Through the above design, the first limiting part 162 narrows the flow channel of the cavity 06 at its location, thereby confining the two floats 13 in the first cavity 061 and the second cavity 062 respectively. The above design allows the two floats to sense the first sensing device and the second sensing device independently. If one float is stuck, the water treatment equipment using the water level monitoring device 100 can determine whether the water level monitoring device has malfunctioned by sensing the other float.

[0030] In some implementations, such as Figure 3 , Figure 4 As shown, the first end 111 has a first port 01, and the second end 112 has a second port 02. The water level monitoring device 100 also includes a cover 17 for sealing the second port 02, and the first port 01 is used to connect to the water tank 200. A pressure balance port 03 is provided on the side of the first end 111 in a direction perpendicular to the axial direction of the tubular structure, and the pressure balance port 03 is used to connect to the interior of the ice-making chamber 300. In actual production and processing, both ends of the tube 06 have openings. One opening is connected to the water tank 200 of the water treatment equipment via a pipeline, and the other opening is sealed by the cover 17. The water level monitoring device 100 is generally vertically installed (relative to the bottom surface of the water treatment equipment) inside the water treatment equipment, and is usually horizontally opposite to the ice-making chamber 300. Placing the pressure balance port 03 on the side of the first end 111 facilitates the installation of a pipeline to connect the pressure balance port 03 to the ice-making chamber 300.

[0031] Specifically, such as Figure 3 As shown, the water level monitoring device 100 is fitted to the side of the ice-making chamber 300. A connector 114 is provided at the first end 111 opposite the side of the ice-making chamber 300. The connector 114 is inserted horizontally into the ice-making chamber 300, connecting the interior of the ice-making chamber 300 to the air pressure balance port 03. This design enhances the compactness of the internal structure of the water treatment equipment.

[0032] In some implementations, such as Figure 3 , Figure 4 As shown, the first sensing device 14 and the second sensing device 15 are respectively disposed on the outer surfaces of the first end 111 and the second end 112. It can be understood that, relative to the bottom surface of the water treatment equipment, the water level monitoring device 100 is typically vertically mounted, and the water level monitoring is longer along the vertical direction, so the space at its two ends is smaller, while the space on its sides is larger. Therefore, placing the first sensing device 14 and the second sensing device 15 on the sides of the first end 111 and the second end 112 provides more space for operation and also facilitates the installation of the electronic circuitry of the first sensing device 14 and the second sensing device 15.

[0033] Please continue reading. Figure 4The aforementioned cover 17 includes a second sealing part 171 and a second limiting part 172 connected to the second sealing part 171. The second sealing part 171 covers the second port 02 and is sealed to the edge of the second port 02. The second limiting part 172 extends a predetermined distance along the axial direction of the tubular structure toward the cavity 06. The floats 13 in the first cavity 061 and the second cavity 062 are respectively the first float 13 and the second float 13. As the first float 13 gradually approaches the first sensing device 14, when the first float 13 first senses the first sensing device 14, the first float 13 abuts against the second limiting part 172.

[0034] It should be noted that the first sensing device 14 and the second sensing device 15 mentioned above can be reed switches or Hall elements. The float 13 is magnetic. When the float 13 is close to the reed switch or Hall element, the reed switch or Hall element will emit a signal.

[0035] For ease of explanation, the first sensing device 14 and the second sensing device 15 are both described below as Hall elements.

[0036] Understandably, the magnetic float 13 will cause the Hall element to emit a signal when it approaches the Hall element from either side. The aforementioned second limiting part can limit the extreme position of the float 13's floating, so that the float 13 will only sense one side of the Hall element during floating, thus avoiding signal failure during use.

[0037] In some implementations, such as Figure 4 As shown, the cover 17 and the limiting member 16 have the same structure. This design reduces the number of parts required during production and enhances the versatility of the parts.

[0038] In some embodiments, a third limiting part (not shown in the figure) is provided on the inner wall of the cavity 06 near the first port 01. As the second float 13 gradually approaches the second sensing device 15, when the second float 13 first senses the second sensing device 15, the second float 13 abuts against the third limiting part. Similar to the second limiting part 172 mentioned above, the second sensing device 15 can also be a Hall element. The third limiting part is used to limit the extreme position of the second float 13, ensuring that the second float 13 only senses one side of the Hall element, thus avoiding signal failure during use.

[0039] In some embodiments, the wall of the middle portion 113 is recessed inward to a predetermined depth to form the limiting structure 12. This design avoids perforating the wall of the tubular structure, further enhancing the integrity of the water level monitoring device 100 and reducing the risk of leakage. Specifically, in actual production and processing, the tubular water level monitor 11 can be made of plastic. The middle portion 113 of the water level monitor 11 can be softened through heat treatment, and then the softened wall of the middle portion 113 is pressed inward to form a recess. Finally, after cooling, the aforementioned limiting structure 12 is formed.

[0040] As shown in Figure 1, Figure 2 As shown, the water treatment equipment provided in this application includes a water tank 200 and the aforementioned water level monitoring device 100. A first connecting structure 04 is connected to the water tank 200. The direction of water level rise and fall in the water tank 200 is set as a first direction X. The extension directions of the first cavity 061 and the second cavity 062 are parallel to the first direction X, forming a communicating vessel with the water tank 200. The aforementioned water level monitoring device 100 has high overall integrity and low risk of leakage, which is beneficial to improving the product quality of the water treatment equipment.

[0041] In some implementations, such as Figure 1 , Figure 2 As shown, the water treatment equipment can be an ice maker, which includes an ice-making chamber 300. The ice-making chamber 300 is in a semi-enclosed state, and a first end 111 is connected to the ice-making chamber 300. The first end 111 is connected to the ice-making chamber 300 to balance the air pressure, allowing the water level monitoring device 100 and the water tank 200 to form a communicating vessel. The water level monitoring device 11 also has a second communicating structure 05 for connecting the interior of the ice-making chamber 300, and the second communicating structure 05 is connected to the first cavity 061. In practical applications, the interior of the ice-making chamber 300 is usually in a semi-enclosed state, making it difficult for foreign objects to enter, thus protecting the airflow inlet and outlet of the water level monitoring device 100 located at the first end 111.

[0042] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
