Description

Technical Field

[0001] This utility model relates to the field of dehumidifier equipment, specifically a dehumidifier with a condensate gravity detection structure. Background Technology

[0002] As living standards continue to improve, people have higher and higher requirements for quality of life, including air humidity. Dehumidifiers are commonly used to reduce air humidity. Dehumidifiers typically have a water tank to collect water droplets formed during the dehumidification process. To prevent the water tank from overflowing and wetting the internal wiring, a water level detection mechanism is required.

[0003] For example, a Chinese patent application with application number CN201510138125.5 discloses a dehumidifier, which may include: a body forming the exterior and having a water tank chamber formed inside; a heat exchange sensor installed inside the body; and a water tank installed in or separated from the water tank chamber via a side of the body for storing condensate generated from the heat exchange sensor; a moving member installed inside the water tank and moving vertically according to the water level of the condensate stored in the water tank; one or more first sensors installed on the wall forming the water tank chamber for detecting the moving member; and a second sensor installed on the wall at a position higher than the first sensors for detecting the moving member.

[0004] As can be seen from the above patent disclosure, traditional dehumidifiers move up and down with the water tank through internal moving components and detect the water level in the tank through Hall sensors. However, since the equipment is immersed in water for a long time, scale easily adheres to its surface and the moving path. If it is not cleaned in time, the accuracy of its measurement will gradually decrease with the increase of usage time. Therefore, it is necessary to design a new dehumidifier with a condensate gravity detection structure. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0031] Example 1

[0032] like Figure 1-8 As shown, the main principle of a dehumidifier is to draw in moisture-saturated air, condense it, collect the moisture, and then expel the dry air, thereby reducing the humidity of the entire indoor air.

[0033] This embodiment provides a dehumidifier with a condensate gravity detection structure, including a dehumidifier housing 1, a water tank 2 and an equipment bracket 3. The equipment bracket 3 is provided with a base 4, a middle mounting plate 5 and a top display screen 6. The base 4, the middle mounting plate 5 and the equipment bracket 3 surround to form a water storage cavity 30. The water tank 2 is detachably installed in the water storage cavity 30. The base 4 is provided with a weighing component 7.

[0034] like Figure 1-3 As shown, the dehumidifier housing 1 is made of plastic injection molding, and the equipment support 3 is placed inside it. A water tank 2 is snapped into the lower rear side of the dehumidifier housing 1 to store the water accumulated during the dehumidifier condensation process.

[0035] like Figures 1-4As shown, the equipment bracket 3 adopts a layered structure design, with a base 4 with casters at the bottom, a middle mounting plate 5 in the middle, and an integrated touch screen display 6 at the top. The base 4, the middle mounting plate 5, and the side walls of the equipment bracket 3 together form a trapezoidal water storage cavity 30, and the detachable water tank 2 slides into the water storage cavity 30 through the bottom opening.

[0036] The weighing assembly 7 includes multiple weighing sensors 71. Multiple weighing slots 40 are provided on the base 4. Each weighing sensor 71 is fixed in the corresponding weighing slot 40. There are two weighing sensors 71, which are symmetrically arranged on both sides of the base 4. The weighing sensors 71 are one of electromagnetic force sensors, capacitive sensors or resistance strain sensors.

[0037] The weighing assembly 7 includes two high-precision resistance strain gauge load cells 71, symmetrically embedded in the weighing slots 40 on both sides of the base 4. Each weighing slot 40 is equipped with a shock-absorbing rubber pad, and the load cells 71 are fixedly connected to the slots 40 by threaded fasteners. The bottom surface 23 of the water tank is precision machined to form a flat load-bearing surface, which is in direct contact with the detection end face of the load cells 71.

[0038] like Figures 4-7 As shown, to ensure installation and positioning accuracy, two parallel plastic guide rods 41 are provided on the base 4, and a guide groove 230 with a self-lubricating bushing is provided on the corresponding bottom surface 23 of the water tank. During installation, the guide rods 41 and the guide groove 230 form a clearance fit to ensure that the water tank 2 is smoothly seated along the predetermined trajectory.

[0039] Elastic limit buckles 31 are also provided on both sides of the equipment bracket 3, and limit slots 210 are provided on the side wall of the water tank body 21. The elastic limit buckles 31 provided on both sides of the equipment bracket 3 are made of polyurethane material and form an interference fit with the limit slots 210 on the side wall of the water tank body 21 to generate an elastic deformation of 1-3mm to achieve reliable fixation.

[0040] like Figure 8 As shown, the top display screen 6 is equipped with a status display area 61, a control button area 62, and a data processor. The water tank 2 includes a tank body 21, a tank cover 22, and a tank bottom surface 23. The tank bottom surface 23 rests against the weighing component 7. The weighing component 7 sends weight data to the data processor, which calculates and sends water level data to the status display area 61 to display the real-time water level. The top display screen 6 integrates an ARM architecture data processor and communicates with the weighing sensor 71 via an RS485 bus. The status display area 61 adopts a dual-mode display design: the stripe display part 611 intuitively reflects the water percentage through the change in the length of the LED light strip, while the numerical display part 612 uses an LCD screen to accurately display the current weight value with an accuracy of ±10g, and the converted water level height.

[0041] A compressor 51 is also installed on the base 4, and a dehumidification system 8 is installed on the middle mounting plate 5. The dehumidification system 8 includes a motor 81, an air duct assembly 82, a condenser 83, and an evaporator 84.

[0042] The dehumidification system 8 adopts a modular design. The base 4 houses the variable frequency compressor 51, and the intermediate mounting plate 5 is fixed with a centrifugal motor 81. Its output shaft is connected to the air duct assembly 82 via a coupling. The air duct assembly 82 adopts an S-shaped flow channel design and sequentially connects to the copper tube condenser 83 with a hydrophilic surface treatment and the finned evaporator 84 to form a complete dehumidification circuit.

[0043] During operation, the data processor collects the detection values ​​from the two weighing sensors 71 in real time, calculates the total weight of the water tank using a weighted average algorithm, and converts this into real-time water level data by combining it with preset water tank volume parameters. When the water level reaches the set threshold, the dehumidification system 8 automatically shuts down and issues an alarm notification on the display screen 6. It can also send data to cloud storage via built-in Wi-Fi and send it to the user's app, reminding the user to remove the water tank 2 and empty the condensate inside.

[0044] This embodiment effectively eliminates off-center loading errors through a symmetrically arranged dual-sensor structure; the design of the guide rod and elastic buckle ensures both measurement accuracy and ease of user assembly and disassembly; the dual-mode display interface balances intuitiveness and accuracy, significantly improving the user experience.

[0045] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
