Description

Technical Field

[0001] The utility model relates to the technical field related to heaters, in particular to a household heater. Background Art

[0002] As the name suggests, a heater is a device that can emit warm air. It mainly works through the suction component to force the indoor cold air to flow into the heater's air inlet, pass through the internal heating element to be heated, and then blown out from the air outlet, achieving the effect of indoor heating.

[0003] Although the existing heaters can meet the heating needs, they still have certain structural deficiencies. For example, the bottom of a floor-standing heater is generally connected to a support foot, and the longitudinal width of the support foot is greater than the width of the outer shell (such as the electric heater disclosed in patent CN204438312U). Therefore, a relatively large packaging box is required for packaging, resulting in high packaging and transportation costs; in addition, the filter on the heater is not convenient to remove, which makes it inconvenient to clean the filter. Utility Model Content

[0004] In order to overcome the existing technical defects, the purpose of the present invention is to provide a household heater to solve the above technical problems.

[0005] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0006] According to one aspect of the present invention, a household heater is designed, comprising: a shell, an air suction component, a heating element, a filter and a supporting foot, the bottom of the shell is provided with an air inlet, the front side of the upper end is provided with an air outlet, the air suction component and the heating element are arranged in the shell, and the heating element is located above the air suction component, a first socket is provided on the right side of the shell, first plug-in slots are provided on both sides of the first socket, the filter is plugged into the first plug-in slot, and the filter is located below the air suction component, four supporting feet are provided, two of which are hinged to the connecting block on the front side of the bottom of the shell, and the other two supporting feet are hinged to the connecting block on the rear side of the bottom of the shell. Rotating the supporting feet can make them folded to the bottom of the shell, and when the supporting feet are in the supporting state, the limiting parts thereon abut against the shell.

[0007] By adopting the above technical solution, the filter is plugged into the first plug-in slot at the first socket position on the shell, which makes it convenient to remove the filter for cleaning. The supporting foot and the connecting block at the bottom of the shell are hinged so that the supporting foot can rotate. When the supporting foot is unfolded, its upper limit portion contacts the shell to keep the supporting foot in a supporting state. When the supporting foot is rotated, it can be folded to the bottom of the shell for folding. After folding, the longitudinal width and vertical height of the heater are relatively reduced, so that a relatively small packaging box can be used for packaging, which can reduce packaging costs and transportation costs.

[0008] In order to better solve the above technical defects, the present invention also has a better technical solution:

[0009] In some embodiments, the housing includes a shell and a bottom plate. The bottom of the shell is open, and a second socket is provided on the right side of the lower end. Second plug-in slots are provided on both sides of the second socket. The air inlet is provided on the bottom plate, and the bottom plate plugs into and mates with the second plug-in slots. Due to long-term operation of the heater, dust will adhere to the outer and inner walls of the air inlet. Currently, dust on the outer wall of the air inlet is generally wiped with a rag, but dust on the inner wall of the air inlet cannot be wiped, resulting in incomplete cleaning. The present technical solution sets the air inlet on the bottom plate, and the bottom plate is connected to the shell by plugging. This allows the bottom plate to be easily removed to clean the inner and outer walls of the air inlet, resulting in more comprehensive cleaning.

[0010] In some embodiments, a movable shutter is further included, and the movable shutter is detachably connected to the air outlet, thereby facilitating the removal of the movable shutter for cleaning.

[0011] In some embodiments, an installation step is provided at the air outlet position, and the edge of the movable shutter is placed in the installation step and connected to the housing by screws.

[0012] In some embodiments, the two front support legs are staggered with the two rear support legs. If the support legs correspond to each other, the front and rear support legs will overlap when folded, resulting in a relatively high overall height of the heater. Staggering the front and rear support legs can reduce the overall height.

[0013] In some embodiments, an air guide shell is installed in the outer shell, the air suction assembly and the heating element are installed in the air guide shell, the air inlet port at the bottom of the air guide shell corresponds to the filter screen, and the air outlet port corresponds to the air outlet.

[0014] In some embodiments, the right end of the filter screen and the right end of the bottom plate are respectively connected to handles, so as to facilitate the removal of the filter screen and the bottom plate.

[0015] In some embodiments, the edge of the filter screen and the edge of the bottom plate are respectively connected with adhesive strips, which can reduce noise pollution caused by vibration. BRIEF DESCRIPTION OF THE DRAWINGS
