Abstract
The utility model discloses a low-temperature and leak-proof heat-pump water pump water heater water tank. The water tank is composed of a side wall body, an upper cover body and a lower cover body. The upper end and the lower end of the side wall body are respectively blocked by the upper cover body and the lower cover body in an enclosed mode. The water tank is characterized in that buffer grooves used for conveniently buffering deformation stress of expansion of a water tank body are formed in at least one wall face of the side wall body, the upper cover body and the lower cover body.
Description
[technical field]
The utility model relates to heat-pump water-heater water tank, relates in particular to a kind of heat-pump water-heater water tank of low temperature leakproof.
[background technology]
When Teat pump boiler used under low temperature environment, water tank was large because of difference variation, caused expanding with heat and contract with cold of metal iron sheet, and volume becomes that large (0 ° the time, the density of ice is 0.9, and the water freezing volume has increased 1.11 times after the water freezing; Below 0 °, the density of ice can drop to 0.8～0.9, and volume has increased 1.11～1.25 times), the volume of water has become opposite pyrocondensation cold expanding, the water tank of Teat pump boiler creates antagonism under the effect of inside and outside deformation force, and stress has caused the phenomenons such as weld seam drawing crack or shell body drawing crack.
[utility model content]
The utility model provides a kind of simple in structure, convenient processing and manufacture, strengthens casing rigidity, overcomes the heat-pump water-heater water tank of the low temperature leakproof of being out of shape under the cryogenic conditions.
In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
A kind of heat-pump water-heater water tank of low temperature leakproof, this water tank is comprised of sidewall bodies, upper cover body and lower cover, and the upper and lower end section of sidewall bodies is respectively by the upper and lower cover body shutoff; At least one wall of described sidewall bodies, upper cover body and lower cover is provided with the dashpot of being convenient to tank box expansion deformational stress buffering.
Described dashpot adopts beading or folding technology to form on sidewall bodies or upper cover body or the lower cover.
Described dashpot is a plurality of annular concentric grooves that are separately positioned on the upper and lower cover surface.
Described dashpot is cannelure, curvilinear shaped slots, straight shape groove, the elliptical slot that is arranged on the sidewall bodies surface.
Described dashpot is to cave in to be arranged on upper cover body or/and the built-in cannelure on lower cover surface.
The beneficial effects of the utility model are:
The utility model is provided with dashpot at least one wall of sidewall bodies, upper cover body and lower cover of heat-pump water-heater water tank, be convenient to tank box expansion deformational stress buffering, can select various types of dashpots as required, also can severally be used, alleviated effectively that water and casing bring under the low temperature adverse circumstances to resistance to deformation, improve the service life of Teat pump boiler.

[specific embodiment]
A kind of heat-pump water-heater water tank of low temperature leakproof, to shown in Figure 16, this water tank is comprised of sidewall bodies 1, upper cover body 2 and lower cover 3 such as Fig. 1, and the upper and lower end section of sidewall bodies 1 is respectively by upper and lower cover body (2,3) shutoff; Described sidewall bodies 1, upper cover body 2 and lower cover 3 at least one wall are provided with the dashpot 4 of being convenient to tank box expansion deformational stress buffering.
Embodiment one
As depicted in figs. 1 and 2, dashpot 4 is for being separately positioned on a plurality of annular concentric grooves of upper and lower cover surface.
Embodiment two
As shown in Figure 3 and Figure 4, described dashpot 4 is for being arranged on the cannelure on sidewall bodies surface.
Embodiment three
As shown in Figure 5 and Figure 6, described dashpot 4 is for being arranged on the curvilinear shaped slots on sidewall bodies surface.
Embodiment four
As shown in Figure 7 and Figure 8, described dashpot 4 is for being arranged on the straight shape groove on sidewall bodies surface.
Embodiment five
As shown in Figure 9 and Figure 10, described dashpot 4 is for being arranged on the elliptical slot on sidewall bodies surface.
Embodiment six
Such as Figure 11 and shown in Figure 12, described dashpot 4 is arranged on the built-in cannelure on upper cover body surface for caving in.
Embodiment seven
Such as Figure 13 and shown in Figure 14, described dashpot 4 is arranged on the built-in cannelure on lower cover surface for caving in.
Embodiment eight
Such as Figure 15 and shown in Figure 16, described dashpot 4 is arranged on the built-in cannelure of upper and lower cover surface for caving in respectively.
The utility model adopts the tank surface at water tank that cannelure, straight shape groove, curvilinear shaped slots are set, the buffer strips such as built-in shape groove, in the process that water tank is made, can select as required various types of buffer strip shape grooves, also can severally be used, adopt beading or folding technology that cannelure, straight shape groove, curvilinear shaped slots or built-in shape groove are formed on sidewall bodies or upper cover body or the lower cover, roll again welding fabrication, make water tank reserve expansive volume, overcome the distortion under the water tank cryogenic conditions, improved the service life of Teat pump boiler.
