Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and in particular to a gas-fired water heater. Background Technology

[0002] Compared to hard water, soft water has many positive effects on the human body. Soft water can better clean the skin and hair, help maintain the skin's moisture and smoothness, reduce discomfort, and bring soothing and relaxation to the mind and body.

[0003] Currently, gas water heaters also incorporate soft water showering functionality, achieving soft water output by periodically adding salt. Existing gas water heaters have the salt tank installed below the casing, with a removable salt tank cover in front. When a salt shortage is detected, the salt tank cover needs to be removed with tools, regenerated salt needs to be added, and then the salt tank cover needs to be reinstalled with tools, which is cumbersome. Summary of the Invention

[0004] This application addresses the shortcomings of existing methods by providing a gas water heater that solves the technical problem of the prior art where, when a salt shortage is detected, the salt tank cover needs to be removed from the salt tank with a tool, then regenerated salt needs to be added to the salt tank, and then the salt tank cover needs to be reinstalled with a tool, which is cumbersome.

[0005] This application provides a gas water heater, comprising: a salt storage container having an installation port; a salt guide having a salt filling port, the salt guide being installed in the installation port and rotating relative to the salt storage container; a movable cover installed on the side of the salt storage container having the installation port, the salt guide abutting against the movable cover; and a movement control component, throttlely connected to the movable cover, for driving the movable cover to move relative to the salt storage container, so that the salt filling port rotation switches between an exposed state and a concealed state.

[0006] As an optional implementation, the movable cover moves between an open state and a closed state; when the movable cover moves to the open state, the salt inlet switches from a hidden state to an exposed state, and the opening of the salt inlet gradually increases. When the movable cover is in the open state, the opening of the salt inlet of the salt guide is at its maximum, used to guide salt into the salt storage container; when the movable cover moves to the closed state, the opening of the salt inlet switches from an exposed state to a hidden state, and the opening of the salt inlet gradually decreases. When the movable cover is in the closed state, the opening of the salt inlet of the salt guide is at its minimum.

[0007] In one optional implementation, the movement control component includes: a drive motor; and a connecting component connected to the drive motor and the movable cover respectively; the drive motor drives the connecting component to move so as to synchronously move the movable cover to an open state, the salt guide flips outward, and the movable cover avoids the salt guide; the drive motor drives the connecting component to move so as to synchronously move the movable cover to a closed state, and the movable cover pushes the salt guide to flip inward.

[0008] As an optional implementation, the movement control component further includes: a guide member disposed on the salt storage container, the guide member being parallel to the movement direction of the movable cover, and the guide member being slidably connected to the connecting component.

[0009] As an optional implementation, the connecting assembly includes: a sliding member connected to a drive motor via a lead screw; and a load-bearing beam, one end of which is connected to the sliding member and the other end of which is connected to the movable cover.

[0010] As an optional implementation, the connecting assembly further includes: a pulley disposed on the load-bearing beam, the pulley having a groove, and the guide member engaging with the groove to achieve connection between the pulley and the guide member.

[0011] As an optional implementation, the sliding member includes: a connecting portion; an extension portion protruding from the connecting portion; and a snap-fit ​​protrusion disposed at an angle to the extension portion at the end of the extension portion away from the connecting portion, for connecting with the load-bearing beam.

[0012] As an optional implementation, the sliding member further includes: a limiting roller, which protrudes from the end of the engaging protrusion away from the extension, the limiting roller and the extension forming a clamping structure, and the load-bearing beam clamped between the limiting roller and the extension.

[0013] As an optional implementation, the load-bearing beam has a structure that is low in the middle and high at both ends. A locking hole is provided in the middle of the load-bearing beam, and the locking protrusion is inserted into the locking hole to realize the detachable connection between the sliding member and the load-bearing beam. The load-bearing beam is provided with pulleys at opposite ends. There are two guide members, which are arranged relatively far apart to be connected to the pulleys at opposite ends of the load-bearing beam respectively.

[0014] As an optional implementation, the gas water heater further includes: a counterweight disposed on the side of the salt guide member facing the movable cover; the salt guide member and the salt storage container are rotatably connected; during the switching phase of the salt guide member from a state where the salt inlet is hidden to a state where the salt inlet is exposed, the salt guide member flips outward under the action of gravity.

[0015] This application provides a gas water heater, and the technical solution provided by the embodiments of this application brings at least the following beneficial effects:

[0016] Once it is determined that the salt storage container is low on salt, the movable cover is moved by the moving control component, causing the salt guide to flip outward and the salt filling port to switch from a hidden state to an exposed state, thus replenishing the salt storage container with salt. After replenishing the salt, the moving control component moves the movable cover again, causing the salt guide to flip inward and the salt filling port to switch from an exposed state to a hidden state. This eliminates the need to disassemble and reassemble the movable cover with tools, achieving the effect of conveniently adding and replenishing salt.

[0039] This application is described in detail below. Examples of embodiments of this application are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. Furthermore, detailed descriptions of known technologies that are unnecessary for the features of this application are omitted. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0040] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0041] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the term “comprising” as used in the specification of this application means the presence of the stated features, elements, and / or components, but does not exclude the presence or addition of one or more other features, elements, components, and / or groups thereof. The term “and / or” as used herein includes all or any units and all combinations thereof of one or more associated listed items.

[0042] like Figure 1-5 As shown in the figure, this application embodiment provides a gas water heater, which mainly includes a salt storage container 1, a salt guide component 2, a movable cover 3, and a movement control component 4. The salt storage container 1 has an installation port; the salt guide component 2 has a salt filling port, and the salt guide component 2 is installed in the installation port and rotates relative to the salt storage container 1; the movable cover 3 is installed on the side of the salt storage container 1 with the installation port, and the salt guide component 2 abuts against the movable cover 2; the movement control component 4 is drivenly connected to the movable cover 3, and is used to drive the movable cover 3 to move relative to the salt storage container 1, so that the rotation of the salt filling port switches between an exposed state and a hidden state.

[0043] In this embodiment, the salt storage container 1 has a cavity for storing salt; optionally, the salt storage container 1 is a box. The salt guide 2 can be flipped outward or inward relative to the salt storage container 1. When the salt guide 2 is flipped outward, it opens the salt filling port, switching the salt filling port from a hidden state to an exposed state. The greater the angle at which the salt guide 2 is flipped outward, the greater the angle at which the salt filling port opens. Conversely, when the salt guide 2 is flipped inward, it closes the salt filling port, switching the salt filling port from an exposed state to a hidden state. The greater the angle at which the salt guide 2 is flipped inward, the smaller the angle at which the salt filling port opens. The flipping angle and direction of the salt guide 2 depend on the moving direction and position of the movable cover 3.

[0044] When the salt inlet is exposed, the salt storage container 1 is connected to the outside through the salt guide 2, and salt can be added to the salt storage container 1 from the outside through the salt inlet; when the salt inlet is hidden, the movable cover 3 covers the salt guide 2, and salt cannot be added to the salt storage container 1 from the outside through the salt inlet.

[0045] The gas water heater provided in this application embodiment, when it is determined that the salt storage container 1 is low on salt, controls the movement of the movable cover 3 through the movement control component 4, causing the salt guide 2 to flip outward and the salt filling port to switch from a hidden state to an exposed state, thus replenishing salt into the salt storage container 1; after replenishing salt, the movement control component 4 controls the movement of the movable cover 3 again, causing the salt guide 2 to flip inward and the salt filling port to switch from an exposed state to a hidden state, so that there is no need to disassemble or assemble the movable cover 3 with tools, achieving the effect of conveniently adding salt.

[0046] like Figure 11-14 As shown, in one optional implementation, the movable cover 3 moves between an open state and a closed state; when the movable cover 3 moves to the open state, the salt inlet switches from a hidden state to an exposed state, and the opening of the salt inlet gradually increases. When the movable cover 3 is in the open state, the opening of the salt inlet of the salt guide 2 is at its maximum, and it is used to guide salt to the salt storage container 1; when the movable cover 3 moves to the closed state, the salt inlet switches from an exposed state to a hidden state, and the opening of the salt inlet gradually decreases. When the movable cover 3 is in the closed state, the opening of the salt inlet of the salt guide 2 is at its minimum.

[0047] Based on the aforementioned embodiments, in this embodiment, the movable cover 3 moves vertically, i.e., upwards or downwards. When the movable cover 3 is in the closed state, at its highest position, it covers the salt guide 2, and the salt inlet of the salt guide 2 is hidden, with the opening of the salt inlet at its minimum. As the movable cover 3 moves downwards, it switches from the closed state to the open state. After the movable cover 3 descends below the salt guide 2, the salt guide 2 flips outwards under gravity, and the salt inlet switches from the hidden state to the exposed state. The salt inlet is exposed, and the opening of the salt inlet gradually increases until the movable cover 3 moves to its lowest position. The top of the movable cover 3 is supported by the salt guide 2. At this time, the movable cover 3 is in the open state, and the opening of the salt inlet of the salt guide 2 is at its maximum.

[0048] The movable cover 3 is in the open state and in the low position. As the movable cover 3 moves upward, it simultaneously pushes the salt guide 2 to flip inward, switching the movable cover 3 from the open state to the closed state. The salt inlet switches from the exposed state to the hidden state, and the opening of the salt inlet of the salt guide 2 gradually decreases until the movable cover 3 rises above the salt guide 2, at which point the opening of the salt inlet of the salt guide 2 reaches its minimum, and the salt inlet is hidden. The movable cover 3 continues to rise, concealing the salt inlet of the salt guide 2, until the movable cover 3 moves to its highest position, at which point the movable cover 3 is in the closed state.

[0049] like Figure 3-5As shown, in one optional implementation, the movement control component 4 includes a drive motor 41 and a connecting component 42. The connecting component 42 is connected to both the drive motor 41 and the movable cover 3. The drive motor 41 drives the connecting component 42 to move, simultaneously causing the movable cover 3 to move to the open state, and the salt guide 2 to flip outward, with the movable cover 3 avoiding the salt guide 2. The drive motor 41 also drives the connecting component 42 to move, simultaneously causing the movable cover 3 to move to the closed state, with the movable cover 3 pushing the salt guide 2 to flip inward.

[0050] Based on the foregoing embodiments, in this embodiment, the drive motor 41 includes a motor and a lead screw. The lead screw is vertically arranged, and the motor can be located above the lead screw. The drive motor 41 is fixed to the salt storage container 1, and correspondingly, the salt storage container 1 has a slot structure for mounting the drive motor 41. The connecting assembly 42 is connected to the lead screw, and the drive motor 41 drives the connecting assembly 42 to move through the lead screw, thereby causing the movable cover 3 to move upward or downward.

[0051] like Figure 5 As shown, as an optional implementation, the movement control component 4 also includes a guide 43, which is disposed on the salt storage container 1. The guide 43 is parallel to the movement direction of the movable cover 3 and is slidably connected to the connecting component 42.

[0052] Based on the aforementioned embodiments, in this embodiment, the guide member 43 is rod-shaped and is vertically fixed to the salt storage container 1. Correspondingly, the salt storage container 1 has a groove structure for installing the guide member 43.

[0053] like Figure 5 As shown, in one optional implementation, the connecting assembly 42 includes a sliding member 421 and a load-bearing beam 422. The sliding member 421 is connected to the drive motor 41 via a lead screw drive; one end of the load-bearing beam 422 is connected to the sliding member 421, and the other end is connected to the movable cover 3.

[0054] Based on the aforementioned embodiments, in this embodiment, the sliding member 421 has a through-hole structure, and the lead screw passes through the through-hole structure to connect the sliding member 421 to the drive motor 41. The load-bearing beam 422 has a certain length, and its two ends are respectively connected to the opposite sides of the movable cover 3. By adopting the above method, the connection stability between the load-bearing beam 422 and the movable cover 3, as well as the movement stability during the movement phase of the movable cover 3, can be guaranteed.

[0055] like Figure 5 As shown, as an optional implementation, the connecting assembly 42 also includes a pulley 423, which is disposed on the load-bearing beam 422. The pulley 423 has a groove, and the guide member 43 is inserted into the groove to realize the connection between the pulley 423 and the guide member 43.

[0056] Based on the aforementioned embodiments, in this embodiment, the pulley 423 has a circular groove arranged circumferentially. The pulley 423 is disposed on the side of the load-bearing beam 422 facing the salt storage container 1 at both ends, and the pulley 423 extends into the groove structure on which the guide member 43 is installed. The guide member 43 is engaged in the circular groove from the outside of the pulley 423, which can prevent the pulley 423 from moving around. At the same time, the pulley 423 itself has very low resistance, which can prevent jamming during the up and down sliding process of the movable cover 3, providing a stable and reliable up and down sliding trajectory guide for the product.

[0057] like Figure 5 and 6 As shown, in one optional embodiment, the slider 421 includes a connecting portion 4211, an extension portion 4212, and a snap-fit ​​protrusion 4213. The extension portion 4212 protrudes from the connecting portion 4211; the snap-fit ​​protrusion 4213 is disposed at an angle to the extension portion 4212 at the end of the extension portion 4212 away from the connecting portion 4211, and is used to connect with the load-bearing beam 422.

[0058] Based on the foregoing embodiments, in this embodiment, the connecting portion 4211 is block-shaped and has the aforementioned through-hole structure, which is vertically oriented axially. The extension portion 4212 extends downward and protrudes from the connecting portion 4211. The snap-fit ​​protrusion 4213 extends horizontally and protrudes from the extension portion 4212.

[0059] Optionally, the connecting part 4211, the extension part 4212 and the snap-fit ​​protrusion 4213 are integrally formed.

[0060] like Figure 6 As shown, in an optional embodiment, the slider 421 further includes a limiting roller 4214, which protrudes from the end of the engaging protrusion 4213 away from the extension 4212. The limiting roller 4214 and the extension 4212 form a clamping structure, and the load-bearing beam 422 is clamped between the limiting roller 4214 and the extension 4212.

[0061] Based on the aforementioned embodiments, in this embodiment, the limiting roller 4214 is rotatably connected to the snap-fit ​​protrusion 4213, the limiting roller 4214 protrudes upward from the snap-fit ​​protrusion 4213, and the limiting roller 4214 and the extension 4212 are spaced apart to form a clamping structure.

[0062] like Figure 5 As shown, in one optional implementation, the load-bearing beam 422 has a structure that is low in the middle and high at both ends. A locking hole 4221 is provided in the middle of the load-bearing beam 422. The locking protrusion 4213 is inserted into the locking hole 4221 to realize the detachable connection between the sliding member 421 and the load-bearing beam 422. Pulleys 423 are provided at opposite ends of the load-bearing beam 422. There are two guide members 43, which are arranged relatively far apart to be connected to the pulleys 423 at opposite ends of the load-bearing beam 422 respectively.

[0063] Based on the aforementioned embodiments, in this embodiment, the gas water heater is equipped with two relatively far-away guide members 43, which can improve the stability of the sliding trajectory guidance. The aforementioned limiting roller 4214 is inserted into the middle locking hole 4221 of the support beam 422, realizing the engagement of the sliding member 421 and the support beam 422. The support beam 422 has a structure that is low in the middle and high at both ends, which is used to adapt to the layout of the low-position movable cover 3 of the drive motor 41 and the high position.

[0064] In one specific embodiment, the load-bearing beam 422 is made of sheet metal, serving as the main load-bearing component. This reduces the rigidity and strength requirements of the movable cover 3, achieving weight reduction and cost reduction. The load-bearing beam 422 includes a beam body 4222 and an adapter frame 4223. The adapter frame 4223 is located at both ends of the beam body 4222, and the two are bolted together. The aforementioned pulleys 423 are fixed at both ends of the beam body 4222. The adapter frame 4223 has mounting holes for connection with the movable cover 3.

[0065] like Figure 7 and 8 As shown, as an optional implementation, the gas water heater also includes a counterweight 5, which is disposed on the side of the salt guide 2 facing the movable cover 3; the salt guide 2 and the salt storage container 1 are rotatably connected; during the switching phase from the state of hiding the salt inlet to the state of exposing the salt inlet, the salt guide 2 flips outward under the action of gravity.

[0066] Based on the aforementioned embodiments, in this embodiment, the counterweight 5 is adhered to the salt guide 2. The counterweight 5 is used to give the salt guide 2 a tendency to flip outward. Under the action of the counterweight 5, the salt guide 2 flips outward, thereby opening the salt inlet.

[0067] like Figure 7-10 As shown, in some embodiments, the salt guiding component 2 includes a salt guiding body 21 and a rotating frame 22. The salt guiding body 21 has a salt guiding channel, the inlet of which serves as a salt filling port; the rotating frame 22 is disposed on the outward side of the salt guiding body 21, the bottom of the rotating frame 22 is rotatably connected to the housing 1, and the top of the rotating frame 22 is rotatably connected to the top of the salt guiding body 21; the counterweight 3 is fixed on the rotating frame 22.

[0068] Based on the aforementioned embodiments, in this embodiment, the rotating frame 22 is used to support the salt-guiding body 21 and enable the salt-guiding body 21 to rotate relative to the box 1. The counterweight 3 is fixed to the side of the rotating frame 22 opposite to the salt-guiding body 21, that is, the outward side, so that the salt-guiding body 21 and the rotating frame 22 can be rotated outward under the action of gravity.

[0069] In some embodiments, the rotating frame 22 includes a crossbeam 221 and two longitudinal beams 222. The crossbeam 221 is centrally located; the two longitudinal beams 222 are respectively located at opposite ends of the crossbeam 221, and each longitudinal beam 222 has a rotating shaft for rotatable connection at opposite ends; wherein, the housing 1 and the salt guide body 21 are both provided with mounting holes that match the rotating shafts.

[0070] Based on the aforementioned embodiments, in this embodiment, the crossbeam 221 is horizontally arranged, the longitudinal beam 222 is perpendicular to the crossbeam 221, and the rotating frame 22 is H-shaped to form a stable support structure. The rotation shafts at the top of the longitudinal beam 222 extend towards each other, and the rotation shafts at the bottom of the longitudinal beam 222 extend away from each other, so as to realize the rotational connection with the box 1 and the salt guiding body 21, respectively.

[0071] In another embodiment, the rotation axes at the top of the longitudinal beam 222 extend in opposite directions; the rotation axes at the bottom of the longitudinal beam 222 extend in opposite directions.

[0072] Optionally, the crossbeam 221 and the longitudinal beam 222 are integrally formed.

[0073] In some embodiments, the salt guiding body 21 includes a salt guiding plate 211 and two surrounding plates 212. The two surrounding plates 212 are angled and disposed opposite to each other at both ends of the salt guiding plate 211 to enclose a groove-shaped salt guiding channel.

[0074] The salt guide plate 211 is used to guide salt. The surrounding plate 212 is triangular, with one side of the surrounding plate 212 connected to the salt guide plate 211, and the surrounding plate 212 is perpendicular to the salt guide plate 211. If the salt guide body 21 is set horizontally, the salt guide plate 211 is located on the horizontal plane, and the salt guide body 21 is U-shaped in the vertical section, that is, the salt guide channel is a U-shaped groove.

[0075] Optionally, the salt guide plate 211 and the two surrounding plates 212 are integrally formed.

[0076] In some embodiments, the salt guide plate 211 includes a plate body 2111 and a first receiving groove 2112. The plate body 2111 has a salt guiding surface on the side away from the rotating frame 22; the first receiving groove 2112 is formed on the side of the salt guide body 21 facing the rotating frame 22, and the first receiving groove 2112 is recessed in a direction away from the rotating frame 22 for accommodating the crossbeam 221 of the rotating frame 22.

[0077] Based on the foregoing embodiments, in this embodiment, the salt-guiding surface is planar to ensure smoothness, reduce resistance, and improve salt-guiding efficiency. The first receiving groove 2112 is adapted to the crossbeam 221 of the rotating frame 22. The first receiving groove 2112 is recessed into the salt-guiding plate 211.

[0078] In some embodiments, the salt guide plate 211 further includes two second receiving grooves 2113, which are formed on the side of the salt guide body 21 facing the rotating frame 22. The second receiving grooves 2113 are recessed in a direction away from the rotating frame 22, and the two second receiving grooves 2113 are relatively far apart, for accommodating the longitudinal beam 222 of the rotating frame 22.

[0079] The second receiving groove 2113 is adapted to the beam of the rotating frame 22. Both second receiving grooves 2113 are connected to the first receiving groove 2112 to adapt to the rotating frame 22. The two second receiving grooves 2113 can be provided at the intersection of the surrounding plate 212 and the salt guide plate 211. The second receiving grooves 2113 are recessed into the surrounding plate 212 and / or the salt guide plate 211.

[0080] In some embodiments, the salt channel protrudes outward from the movable cover 3 and extends inward into the main body of the salt storage container 1.

[0081] By adopting the above solution, the longer salt channel can separate the rotating frame 22 and each component, thereby preventing salt particles from getting stuck in the gaps between the components and fundamentally solving the problem of component jamming and damage.

[0082] In some embodiments, the salt storage container 1 includes a housing 11 and an abutment protrusion 12. The housing 11 has a receiving cavity for containing salt inside, and the housing wall of the housing 11 has an opening communicating with the receiving cavity. The edge of the opening is rotatably connected to the salt guide member 2. The abutment protrusion 12 is disposed in the receiving cavity and close to the edge of the opening. The abutment protrusion 12 extends into the receiving cavity to abut against the side of the salt guide body 21.

[0083] One end of the abutment protrusion 12 is fixed to the inner wall of the box 11, and the other end extends into the box 11 to abut against the side of the salt guiding body 21, so that the salt guiding component 2 is away from the opening and forms a greater inclination. When the movable cover 3 slides down, the salt guiding component 2 flips outward under the action of the counterweight 5. Its flipping angle is limited by the contact positions between the two sides of the rotating frame 22 and the movable cover 3. At this time, the salt guiding body 21 flips open under the drive of the rotating frame 22, and the salt guiding body 21 will rotate along the common axis of both sides. Since the rotation angle is limited by the contact between the side of the salt guiding body 21 and the abutment protrusion 12, the movement posture of the salt guiding body 21 is a compound movement of outward flipping and outward sliding.

[0084] In some embodiments, the gas water heater further includes a voice reminder device, a control unit, and a weight sensor. The control unit connects to and controls the voice reminder device and the weight sensor. The weight sensor can be a pressure sensor. The weight sensor is used to detect the weight of the salt storage container 1, which includes the weight of the salt storage container 1 itself and the weight of the salt inside the salt storage container 1. When the weight data detected by the weight sensor is less than a preset warning weight data, the control unit controls the voice reminder device to emit an audible message to provide a reminder.

[0085] In one specific embodiment, the gas water heater also includes a confirmation button. The control unit acquires data detected by the weight sensor in real time. When the measured weight is less than 300g, corresponding to approximately 50g of salt, the control unit controls the voice reminder device to issue a voice reminder and simultaneously activates the confirmation button. When the user receives the reminder and prepares to add salt to the salt tank, they click the confirmation button, ending the voice reminder. The control unit then controls the drive motor 41 to move the sliding cover 3, exposing the salt filling port to complete the salt addition. During this process, the confirmation button is disabled, and its operation is ineffective. After salt addition is complete, the user clicks the confirmation button again, and the control unit controls the drive motor 41 to move the sliding cover 3, concealing the salt filling port. The control unit then again acquires data detected by the weight sensor in real time.
