Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, and particularly relates to a water heater with an adjustable internal volume. Background Art

[0002] Water heaters can be divided into electric water heaters and steam water heaters according to the heating source. Among them, electric water heaters can be further subdivided into traditional water heaters, boiling water heaters, step-by-step water heaters, instant water heaters, heat-push instant water heaters, and electromagnetic water heaters according to the heating principle. In addition, water heaters can also be divided into storage water type water heaters and instant water heaters according to the working form, and steam water heaters are divided into intermittent steam water heaters and continuous steam water heaters.

[0003] In the prior art, the storage water volume of most water heaters is constant, which is not convenient for adjusting the water storage volume and may cause many inconveniences. Moreover, most water heaters are directly mounted on the mounting rack. However, when the water heater heats the water source, the water heater may vibrate. Since it is directly mounted without limiting and fixing, the mounting stability may be affected.

[0004] Therefore, a water heater with an adjustable internal volume is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a water heater with an adjustable internal volume to solve the problems raised in the above background art.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A water heater with an adjustable internal volume includes a fixed box and a mounting rack. A cold water pipe is arranged on one side of the fixed box, a hot water pipe is arranged on one side of the fixed box, a heater is arranged inside the fixed box, an expansion mechanism for adjusting the volume space is arranged on the fixed box, a control panel is arranged on one side of the fixed box, a mounting mechanism for mounting and hanging the fixed box on the mounting rack is arranged on one side of the mounting rack, and the mounting mechanism is arranged on one side of the fixed box, and a limiting mechanism for locking and limiting is arranged on the mounting mechanism.

[0008] Further, the expansion mechanism includes four fixing plates, which are respectively installed on the left and right sides of the fixed box. A lead screw is rotatably installed between the two fixing plates on the left, a fixed column is installed between the two fixing plates on the right, a connecting plate is threadedly installed on the outer wall of the lead screw, and the connecting plate is slidably installed on the outer wall of the fixed column. A motor is installed at the bottom of the lead screw, and the motor is installed on the surface of the fixing plate.

[0009] Further, a sliding groove is formed in the top of the fixed box. A fixed shell is installed at the bottom of the connecting plate, and the fixed shell is slidably installed inside the sliding groove. A water blocking strip is arranged on the top of the fixed box, and the water blocking strip is in contact with the fixed shell.

[0010] Further, the installation mechanism includes two connecting rods. The two connecting rods are installed on the surface of the mounting frame. Connecting shells are installed on the surfaces of the two connecting rods. T-shaped rods are slidably installed on the inner walls of the two connecting shells, and the T-shaped rods are installed on the surface of the fixed box.

[0011] Further, the limiting mechanism includes a spring. The spring is arranged on the surface of the upper connecting shell. A fixed rod is arranged at the top end of the spring. A cylinder is arranged at the bottom of the fixed rod, and the cylinder is arranged inside the spring. A plugging block is installed at the bottom of the cylinder, and the plugging block is slidably installed on the connecting shell and the T-shaped rod.

[0012] Further, the number of the plugging blocks, the cylinders and the springs is all set to three, and they are arranged in a linear array. The shapes of the three plugging blocks are different from each other.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In the present utility model, through the settings of the spring, the plugging block and the T-shaped rod, etc., during use, first, the mounting frame is fixed on the wall surface by expansion bolts. By pulling the fixed rod, the cylinder and the plugging block are driven to move upward, and the spring is involved. One end of the T-shaped rod slides into the connecting shell. Then, the fixed rod is released. Under the restoring elastic force of the spring, the plugging block, the cylinder and the fixed rod are driven to reset. The plugging block contacts the surface of the T-shaped rod, pushes the fixed box, and drives the T-shaped rod to slide in the connecting shell. When the plugging block meets the insertion opening of the T-shaped rod, under the restoring elastic force of the spring, the plugging block slides into the insertion opening, that is, the installation of the T-shaped rod and the connecting shell is locked. On the contrary, the T-shaped rod can be unlocked and disassembled, so as to facilitate the installation and disassembly of the fixed box, facilitate later maintenance, and have a good mounting stability effect.

[0015] In the present utility model, through the settings of the lead screw, the connecting plate and the fixed shell, etc., by controlling the start of the motor through the control panel, the lead screw is driven to rotate, so that the connecting plate slides longitudinally on the fixed column, and drives the fixed shell to slide longitudinally in the sliding groove.

[0027] As Figures 1-3 shown, the expansion mechanism 4 includes four fixing plates 401, and the four fixing plates 401 are respectively installed on the left and right sides of the fixed box 1. A lead screw 402 is rotatably installed between the two left fixing plates 401, a fixed column 403 is installed between the two right fixing plates 401, a connecting plate 404 is threadedly installed on the outer wall of the lead screw 402, and the connecting plate 404 is slidably installed on the outer wall of the fixed column 403. A motor 408 is installed at the bottom of the lead screw 402, and the motor 408 is installed on the surface of the fixing plate 401. In this embodiment, the motor 408 is started to drive the lead screw 402 to rotate, so that the connecting plate 404 slides longitudinally on the fixed column 403, thereby adjusting the height of the connecting plate 404.

[0028] As Figures 2-3As shown, a sliding groove 406 is formed at the top of the fixed box 1. A fixed shell 405 is installed at the bottom of the connecting plate 404, and the fixed shell 405 is slidably installed inside the sliding groove 406. A water blocking strip 407 is arranged at the top of the fixed box 1, and the water blocking strip 407 is in contact with the fixed shell 405. In this embodiment, through the longitudinal movement of the connecting plate 404, the fixed shell 405 is longitudinally slid inside the sliding groove 406. With the cooperation of the fixed box 1, the connecting plate 404 and the fixed shell 405, the storage volume of water can be expanded.

On the contrary, slide the T-shaped rod 703 into the connecting shell 702, release the fixing rod 804, and under the restoring elastic force of the spring 803, drive the insertion block 801, the cylinder 802 and the fixing rod 804 to reset. The insertion block 801 is inserted into the insertion interfaces on the connecting shell 702 and the T-shaped rod 703 to lock it. By setting the number and orientation of the insertion blocks 801, the cylinders 802 and the springs 803, the locking stability is improved. Moreover, since the shapes of the three insertion blocks 801 are different, it is not necessary to always pull the fixing rod 804. Just misalign the insertion interface of the insertion block 801 and the T-shaped rod 703 to release the fixing rod 804, and then push the T-shaped rod 703, which is convenient for installation and disassembly.
