Abstract
The utility model provides a water heater of nail -free installation backplate, its includes heater shell and locate the water container in its, its characterized in that is installed at the backplate at the back of shell: the back of shell be provided with the draw -in groove, be provided with the buckle on the backplate, the backplate passes through the buckle to be fixed in the draw -in groove of shell. The draw -in groove cross -section be " U " font, by the preparation shaping of buckling of shell panel. The beneficial effects of the utility model are that: 1 the utility model has the advantages of simple structure, equipment convenience, low in production cost, market competition is strong. 2, adopt the buckle installation between backplate and shell, the installation complicacy when consequently avoiding the screw fixation is loaded down with trivial details, has improved production efficiency. 3, buckle formula installation fashion handsome in appearance is avoided producing the indentation because of the installation screw causes the backplate.
Description
Technical field
The utility model relates to a kind of water heater, and specifically a kind of exempting from follows closely the water heater installing backboard.
Background technology
Storage-type electric water heater is high due to technology maturation, security performance, is extensively adopted at present by Chinese family.This electric heater generally includes the inner bag of water storage, is arranged in inner bag to be used for the electrically heated rod of heating water, coated heat-insulation layer outside the tank and shell.Traditional electric heater mainly adopts columniform structure, after therefore it is installed, there is a large amount of space waste between its back and metope.Therefore occurred square water heater on the market, this kind of water heater adopts two water container structure mostly, while increase moisture storage capacity, utilizes square shell that it is coatedly played space-saving effect.Therefore this kind of shell generally comprises front casing and backboard, and backboard uses screw to be fixed on shell usually.Through the calculating of the applicant, each backboard needs the screw of installation 10 to 15 according to its size, and the set-up time is probably effect in 2 to 3 minutes.Therefore Manufacturing Worker needs long-time mechanized operation, while causing production cost higher, brings the injury of arriving also to very the health of Manufacturing Worker.In addition, because backboard generally adopts sheet metal to make, therefore once after screw installation, impression will be formed on the backboard at screw place, also can affect its overall appearance effect time serious.Therefore be necessary to do further to improve to existing water heater back board structure.
Utility model content
The purpose of this utility model is the shortcoming existed to overcome prior art, and provide a kind of structure simple, easy to use, production cost is low, and structural approach is novel, and a kind of exempting from quick and easy for installation follows closely the water heater installing backboard.
The utility model object realizes with the following methods: a kind of exempting from follows closely the water heater installing backboard, it comprises outer cover of water heater and establishes water courage in the inner, the back of shell is arranged on backboard, it is characterized in that: the back side of described shell is provided with draw-in groove, backboard is provided with buckle, and backboard is fixed by snap in the draw-in groove of shell.
Described draw-in groove cross section, in " U " font, bends making by shell sheet material shaping.
Described buckle is the flange that back plate edges bends downwards, and scrap (bridge) is snapped into draw-in groove internal fixtion.
Described flange cross section is vertical bar shape, fixes with draw-in groove interference fit
Described flange cross section is arch shape, and elasticity holding is at draw-in groove internal fixtion.
Described flange cross section is in " ︿ " shape, and elasticity holding is at draw-in groove internal fixtion.
The beneficial effects of the utility model are: 1, to have structure simple, easy to assembly for the utility model, the advantages such as production cost is low, and the market competitiveness is strong.2, adopt buckle to install between backboard and shell, installation complexity when therefore avoiding screw to fix is loaded down with trivial details, improves production efficiency.3, buckle-type installs fashion handsome in appearance, avoids causing backboard to produce impression because installing screw.

Detailed description of the invention
Below in conjunction with accompanying drawing, concrete further instruction is done to the utility model.A kind of exempting from follows closely the water heater installing backboard, it comprises outer cover of water heater 1 and establishes water courage 2 in the inner, and the back of shell 1 is arranged on backboard 3, it is characterized in that: the back side of described shell 1 is provided with draw-in groove 4, backboard 3 is provided with buckle, and backboard is fixed by snap in the draw-in groove 4 of shell 1.
Described draw-in groove 4 cross section, in " U " font, bends making by shell 1 sheet material shaping.
Described buckle is the flange 5 that backboard 3 edge bends downwards, and scrap (bridge) is snapped into draw-in groove 4 internal fixtion.
As described in Figure 5, described flange 5 cross section is vertical bar shape, fixes with draw-in groove 4 interference fit
As described in Figure 6, described flange 5 cross section is arch shape, and elasticity holding is at draw-in groove 4 internal fixtion.
As described in Figure 7, described flange 5 cross section is in " ︿ " shape, and elasticity holding is at draw-in groove 4 internal fixtion.
Operation principle: in this case, is provided with draw-in groove and flange respectively on shell and backboard, when backboard installed by needs, directly the flange on backboard is snapped in draw-in groove and can be fixed.Draw-in groove is utilized to be gripped by flange.Wherein in order to strengthen bonding strength between the two, the flange Cross-section in this case, except using vertical bar shape, also can be set to arch type or " ︿ " shape.The Elastic buckle of flange sheet material self is utilized to be fixed in draw-in groove.Compared with the fixed form using screw with conventional art, in this case, fastening type structure installation effectiveness can promote more than 50%.Also avoid making to be screwed easily on backboard, producing impression simultaneously, ensure that the profile of this water heater is complete attractive in appearance, therefore can extensively promote the use of.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
