Description

Technical Field

[0001] The present invention relates to the technical field of control equipment, and in particular to a liquid stop valve and a dehumidifier. Background Art

[0002] With the continuous improvement of people's living standards, evolving consumer preferences, and increasing awareness of health, dehumidifiers are gradually expanding from commercial use to home use, becoming an indispensable modern household appliance for many families. Dehumidifiers can be categorized by function into general, cooling, thermostatic, and multifunctional types. A general dehumidifier cools and dehumidifies air through an evaporator, then heats it up in a reheater to lower the relative humidity. The refrigerant's heat of condensation is entirely removed by the air flowing through the reheater, and the outlet air temperature cannot be adjusted. This dehumidifier is used solely for heating and dehumidification. A cooling dehumidifier is a dehumidifier that, in addition to a general dehumidifier, removes most of the refrigerant's heat of condensation by a water- or air-cooled condenser, leaving only a small portion used to heat the air after the evaporator. This dehumidifier can be used for cooling and dehumidification. A thermostatic dehumidifier is a dehumidifier that, in addition to a general dehumidifier, removes all or part of the refrigerant's heat of condensation by a water- or air-cooled condenser, leaving the remaining heat used to heat the air after the evaporator. The outlet air temperature can be adjusted. A multifunctional dehumidifier refers to a dehumidifier that integrates three functions: heating dehumidification (general type), cooling dehumidification, and temperature-controlled dehumidification. Even when there is no outdoor unit (air-cooled) or cooling water (water-cooled), the heating dehumidification function can still be selected for dehumidification.

[0003] Currently, most dehumidifiers on the market face a problem: when the water tank assembly is removed, the water in the water tray will flow out through the drain hole and drain nozzle and finally flow onto the floor. Summary of the Invention

[0035] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, the descriptions of "first", "second", etc. in the present invention are for descriptive purposes only and should not 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" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. 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 required by the present invention.

[0039] The present invention proposes a liquid stop valve, which is installed on a preset device and is used to control the opening and closing of the liquid outlet of the preset device, wherein the liquid stop valve includes: a movable part, a fixed part and an elastic part, the movable part is movably arranged on the preset device, and has a sealing part for sealing the liquid outlet and a movable part extending to the bottom of the liquid outlet, and the movable part can drive the sealing part to separate from the liquid outlet under the action of external force; the fixed part is fixedly installed above the movable part to limit the movable part; the elastic part is connected between the fixed part and the movable part, and the elastic part is used to reset the movable part when there is no external force on the movable part.

[0040] See Figure 4-9 The liquid stop valve 600 of the embodiment of the present application includes: a movable part 610, a fixed part 630 and an elastic part 620, wherein the movable part 610 is movably arranged in a preset device, and has a blocking portion for blocking the liquid outlet 511 and a movable part extending to the bottom of the liquid outlet 511, and the movable part can drive the blocking portion to separate from the liquid outlet 511 under the action of an external force; the fixed part 630 is fixedly installed above the movable part 610 to limit the movable part 610; the elastic part 620 is connected between the fixed part 630 and the movable part 610, and the elastic part 620 is used to reset the movable part 610 when there is no external force on the movable part 610. Figure 4 As shown, Figure 4 A schematic diagram shows the liquid stop valve 600 of an embodiment of the present application installed in a preset device state. The liquid stop valve 600 of the embodiment of the present application can control the opening and closing of the liquid outlet 511 of the preset device in the installed state, ensuring the timeliness of the opening and closing of the liquid outlet 511, and avoiding the problem of liquid leakage caused by the liquid outlet 511 not closing in time or not sealing.

[0041] See Figure 7 The movable member 610 includes a movable bracket 611 and an elastic plug 612. The elastic plug 612 is disposed at the bottom of the movable bracket 611. A movable shaft 614 is disposed at each end of the movable bracket 611. The bottom end of the movable shaft 614 is a movable portion that can penetrate the preset device. A movable main shaft 613 is disposed in the middle of the two movable shafts 614. The movable main shaft 613 can penetrate the fixed member 630. The elastic member 620 is sleeved on the outside of the movable main shaft 613 and limited between the movable member 610 and the fixed member 630. Preferably, the two movable shafts 614 and the movable main shaft 613 are both vertically disposed on the movable bracket 611. The elastic plug 612 is the sealing portion for sealing the liquid outlet 511. Due to its elasticity, it can adapt to the outer edge of the liquid outlet 511, so that the liquid stop valve 600 can better seal the liquid outlet 511 when sealing the liquid outlet 511. It can be understood that the number of movable shafts 614 of the movable part 610 in the embodiment of the present application is not limited to two. The movable part 610 in the embodiment of the present application is provided with two to achieve more balanced and uniform force. Those skilled in the art can flexibly adjust the number of movable shafts 614 according to actual applications, and can also provide one or more as needed. No further details will be given here.

[0042] like Figure 8 As shown, the elastic plug 612 is provided with a locking portion at the top, which includes a guide cone section 6121 and a locking column 6122. The outer diameter of the guide cone section 6121 gradually expands from top to bottom, and the locking column 6122 is provided at the bottom of the guide cone section 6121, and the outer diameter of the locking column 6122 is smaller than the outer diameter of the bottom of the guide cone section 6121. The bottom of the movable bracket 611 is provided with a receiving cavity 6111. The bottom of the receiving cavity 6111 is open and is used to accommodate the guide cone section 6121. The open end of the receiving cavity 6111 mates with the outer edge of the locking column 6122. The guide cone section 6121 has a guiding slope for facilitating installation into the receiving cavity 6111 at the bottom of the movable bracket 611. The outer diameter of the locking column 6122 is smaller than the outer diameter of the bottom of the guide cone section 6121, so that the elastic plug 612 is fixed to the movable bracket 611. Preferably, the elastic plug 612 is made of silicone.

[0043] Furthermore, the bottom of the elastic plug 612 has a first fitting bevel 6123, which is an annular bevel with a gradually decreasing inner diameter from top to bottom. The upper edge of the liquid outlet 511 has a second fitting bevel 560 that matches the first fitting bevel 6123. The arrangement of the first fitting bevel 6123 and the second fitting bevel 560 provides the dehumidifier of the present embodiment with a better liquid-stopping effect, effectively preventing liquid leakage.

[0044] Further, see Figure 9 The fixing member 630 includes a fixing bracket 631. A guide hole 6311 is provided in the middle of the fixing bracket 631. The movable main shaft 613 can pass through the guide hole 6311. The fixing bracket 631 has mounting holes 6313 protruding outward at both ends. A detachable connecting member can pass through the mounting holes 6313 to fix the fixing bracket 631 to the preset device. When the movable member 610 moves under the action of an external force, since the fixing member 630 is fixed to the preset device through the mounting holes 6313 and the movable member 610 is set at the bottom of the fixing bracket 631, the fixing bracket 631 can limit the upward movement of the movable member 610. In addition, the movable main shaft 613 of the movable member 610 passes through the guide hole 6311 of the fixing bracket 631 to limit the movement direction of the movable member 610 and prevent it from misalignment.

[0045] In an optional embodiment of the present application, an elastic member 620 is connected between the fixed member 630 and the movable member 610. The elastic member 620 is used to reset the movable member 610 when no external force is applied to the movable member 610. The elastic member 620 is preferably a spring, which is sleeved on the outside of the movable main shaft 613. The lower end of the elastic member 620 abuts against the movable bracket 611, and the upper end of the elastic member 620 abuts against the spring contact surface 6312 of the fixed bracket 631. When the movable member 610 moves upward under the action of an external force, the blocking portion moves away from the liquid outlet 511. At this time, the liquid outlet 511 is opened, and the elastic member 620 is constrained between the movable member 610 and the fixed member 630 and is compressed. When the movable member 610 is not operating under external force, or the external force applied to the movable member is less than the elastic force of the elastic member 620, the elastic member 620 resets and drives the movable member 610 to move downward, thereby causing the blocking portion to block the liquid outlet 511.

[0046] The liquid-stop valve 600 of the embodiment of the present application can be widely used in various pre-set devices and equipment. By way of example, and not limitation, the liquid-stop valve 600 of the embodiment of the present application can be used in a dehumidifier. Dehumidifiers are a preferred application embodiment of the liquid-stop valve 600 of the present application, and their practical applications include, but are not limited to, dehumidifiers. Those skilled in the art can flexibly apply the liquid-stop valve 600 of the present application to other fields, such as liquid pipeline transportation, based on actual circumstances. The liquid-stop valve 600 of the present application has a simple structure and strong practicality.

[0047] The present invention also provides a dehumidifier, see Figure 1-15 The dehumidifier includes a dehumidifier body, a liquid storage tank 400 and a liquid stop valve 600, wherein the specific structure of the liquid stop valve 600 can refer to the above embodiment. Since the dehumidifier of this embodiment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0048] Specifically, the dehumidifier body has a liquid outlet 511, and the liquid storage tank 400 is arranged below the liquid outlet 511 for carrying the liquid flowing out of the liquid outlet 511. The stop valve 600 is arranged at the liquid outlet 511 for controlling the opening and closing of the liquid outlet 511 of the dehumidifier body. When the liquid storage tank 400 is separated from the dehumidifier body, the stop valve 600 blocks the liquid outlet 511; when the liquid storage tank 400 is connected to the dehumidifier body, the liquid storage tank 400 abuts against the movable part 610 of the stop valve 600, causing the movable part 610 to move upward, thereby driving the sealing part to separate from the liquid outlet 511, and forming a gap between each other, so that the liquid can flow into the liquid storage tank 400 through the liquid outlet 511.

[0049] In some optional embodiments, such as Figure 1-3As shown, the dehumidifier body includes a front housing 100, a rear housing 200, an air inlet grille 300, a liquid storage tank 400, a liquid collection tray assembly 500, a bottom pan assembly 700, a compressor, an evaporator, a condenser, a fan, etc. Specifically, the liquid collection tray assembly 500 includes a liquid collection tray 510, which has a liquid outlet 511. A drain nozzle 520 is provided at the bottom of the liquid collection tray 510 and is connected to the liquid outlet 511. The drain nozzle 520 is used to direct liquid flowing out of the liquid outlet 511 to the liquid storage tank 400. Furthermore, a blocking portion 521 is provided at the bottom of the drain nozzle 520 to guide liquid flowing along the lower wall of the drain nozzle 520. The cross-section of the barrier portion 521, perpendicular to the central axis of the drain nozzle, is a quadrilateral. The upper edge of the quadrilateral aligns with the outer wall of the drain nozzle 520, the two sides of the quadrilateral are parallel, and the lower edge of the quadrilateral extends downward from the outer wall of the drain nozzle 520 to form a plate-like structure, forming a barrier. The barrier portion 521 is used to prevent liquid in the liquid collection tray 510 from flowing down the lower wall of the drain nozzle 520 and then along the inner wall of the liquid collection tray 512 to the floor. Some liquid drips along the barrier portion 521 into the liquid storage tank 400 within the liquid receiving area.

[0050] Further, see Figure 11 The liquid storage tank 400 includes a boss 410, which includes a boss slope 411 and a boss top plane 412. The boss top plane 412 is arranged horizontally, with the upper edge of the boss slope 411 connected to the boss top plane 412, and the lower edge of the boss slope 411 is arranged to continuously decrease in the direction closer to the dehumidifier body. The boss slope 411 can abut against the movable part, driving the movable part to move upward, thereby separating the blocking part from the liquid outlet 511. The boss top plane 412 is used to support the movable part so that the blocking part is located above the liquid outlet 511 when separated from the liquid outlet 511. The boss 410 of the liquid storage tank 400 is used to provide external force to the movable part 610 of the liquid stop valve 600. When the force exerted by the boss 410 on the movable bracket 611 of the liquid stop valve 600 is greater than the force exerted by the elastic member 620 on the movable bracket 611, the movable bracket 611 moves upward, driving the elastic plug 612 to move upward synchronously, and the liquid outlet 511 opens; when the force exerted by the elastic member 620 on the movable bracket 611 is greater than the force exerted by the boss 410 on the movable bracket 611 or the movable bracket 611 is not subjected to force, the movable bracket 611 moves downward, driving the elastic plug 612 to move downward synchronously to block the liquid outlet 511.

[0051] In practical applications, such as Figure 12 and Figure 13As shown, during the process of converting the liquid storage tank 400 and the dehumidifier body from a separated state to an installed state, the boss slope 411 on the liquid storage tank 400 guides and slowly lifts the movable shaft 614 on the movable bracket 611 until the movable shaft 614 on the movable bracket 611 is pushed to the boss top plane 412 on the liquid storage tank 400. At this time, the entire movable bracket 611 is no longer pushed up, and the elastic plug 612 is also brought to a certain height by the movable bracket 611. The first fitting slope 6123 on the elastic plug 612 is separated from the second fitting slope 560 on the liquid collection tray 510 and a certain gap is generated. As a result, the liquid received by the liquid collection tray 510 will flow into the liquid storage tank 400 through the liquid outlet 511 and the drain nozzle 520.

[0052] See Figure 14 and 15 When the liquid storage tank 400 is pulled out, the movable bracket 611 and the elastic plug 612 are lowered by the action of the elastic member 620, and the first fitting slope 6123 on the elastic plug 612 is pressed against the second fitting slope 560 on the liquid collection tray 510 to form a seal. Therefore, when the liquid storage tank 400 is pulled out, the liquid in the liquid collection tray 510 will no longer flow out through the liquid outlet 511 and the drain nozzle 520.

[0053] In some optional embodiments, the dehumidifier body further includes a sleeve 530 extending upward from the upper surface of the liquid collection tray 510. The sleeve 530 is disposed around the liquid outlet 511 and has an axial hole 532 therein for the movable portion to pass through. A first liquid retaining rib 531 of a predetermined height is disposed around the outer wall of the sleeve 530. The first liquid retaining rib 531 is used to prevent liquid received by the liquid collection tray 510 from flowing out of the sleeve 530.

[0054] In other optional embodiments, the dehumidifier body further includes a mounting post 540, which extends upward from the upper surface of the liquid collection tray 510. Preferably, the fixing bracket 631 includes two mounting holes 6313, and the number of mounting posts 540 corresponds to the number of mounting holes 6313. The detachable connector is fixed to the mounting post 540 through the mounting hole 6313, thereby fixing the fixing bracket 631 to the dehumidifier body. Preferably, the mounting hole 6313 is a threaded hole, and the mounting post 540 is a threaded post. The mounting post 540 and the sleeve 530 are staggeredly arranged around the liquid outlet 511, and a second liquid retaining rib 550 of a preset height is provided around the outer wall of the mounting post 540. The second liquid retaining rib 550 is used to prevent the liquid received by the liquid collection tray 510 from flowing out of the mounting post 540.

[0055] The following is a detailed description of the process of installing the liquid stop valve 600 in the dehumidifier. In the liquid stop valve 600 of the embodiment of the present application, the movable bracket 611 of the movable part 610 is detachably connected to the elastic plug 612. The elastic plug 612 is installed in the accommodating cavity 6111 on the movable bracket 611 through the guide cone section 6121 on it, and is prevented from falling off by the clamping column 6122 on it. Figure 4 、 6 As shown in Figures 13 and 15, the movable shaft 614 on the movable bracket 611 with the elastic plug 612 installed is inserted into the sleeve 530, and then the elastic member 620 is sleeved onto the movable main shaft 613 on the movable bracket 611. The fixed bracket 631 is then sleeved onto the movable main shaft 613 on the movable bracket 611 through the guide hole 6311. The fixed bracket 631 is then fixed to the liquid collection tray 510 using a detachable connecting member through the mounting hole 6313 on the fixed bracket 631 and the mounting post 540 on the liquid collection tray 510. At this time, the top of the elastic member 620 contacts the spring contact surface 6312 on the fixed bracket 631 and receives force, while the bottom of the elastic member 620 contacts the movable bracket 611 and receives force, thereby completing the installation of the liquid stop valve 600.

[0056] In actual use, when the liquid storage tank 400 is installed in the dehumidifier body, the liquid in the liquid collection tray 510 can flow normally into the liquid storage tank 400. When the liquid storage tank 400 is removed, the liquid in the liquid collection tray 510 will no longer flow out through the liquid outlet 511 and the drain nozzle 520 and onto the floor, effectively improving the user experience.
